초록

This study examines the nonlinear relationship between financial development and economic growth in Pakistan using the threshold regression model for the period 1980-2017. We also employed quantile regression with 0.25, 0.50, and 0.75 quantiles of conditional distribution. The quantile regression is based on minimizing of sum of squared residuals. The result indicates that economic growth responds positively to financial development when the level of financial development surpasses the threshold value of 0.151. However, when financial development lies below the threshold value (that is, 0.151), its impact on economic growth is negative. Thus, when financial development of Pakistan surpasses the threshold level, it contributes more towards economic growth since greater level of financial development contributes more to boosts economic growth. This finding reveals that economic growth reacts differently to financial development, and the relationship between financial development and economic growth is U-shaped in Pakistan. Among the other variables, physical capital, labor force, and government expenditure exert a positive effect on economic growth. Furthermore, inflation rate and trade openness have an insignificant impact on economic growth. The results of quantile regression also confirm the non-linear relationship between financial development and economic growth in Pakistan. The finding of this study suggests revamping of financial sector policies in Pakistan.

1. Introduction

Financial development deals with the policies, processes, and strategies to enhance the financial access, depth, and efficiency of the financial institutions and financial markets. A well-developed financial system enhances economic efficiency by channeling scarce resources to the most efficient uses that lead to sustainable growth (Slesman, Baharumshah, & Azman-Saini, 2019). The impact of finance on growth has been at the center of most policy debates among the researchers over the past few decades (Ang & McKibbin, 2007; Seven & Yetkiner, 2016). Theoretical literature suggests that financial development can promote economic growth through the pooling of savings, risk reduction and risk management, facilitation of exchange via reduction of transaction costs, information sharing about investment opportunities, improvement of capital allocation, and the increase of investor’s willingness to finance new projects through monitoring corporate governance (King & Levine, 1993; Levine, 2005).

Most of the empirical literature (for example, King & Levine, 1993; Levine, 1998) concluded that there is a positive relationship between finance and growth, while Fisman and Love (2002) and Demirgus-Kunt and Maksimovic (2002) documented similar relationship at industry and firm-levels, respectively. Notwithstanding, finance-growth literature predicted four possible directions. First, finance is an engine of economic growth (Schumpeter, 1912; McKinnon, 1973; Shaw, 1973; Levine, 2005). They considered savings and investments, and allocation of funds to productive sectors as important channels through which efficiency of capital increases, which in turn enhances economic growth (AlYousif, 2002; King & Levine, 1993; Masten, Coricelli, & Masten, 2008). Second, economic growth drives the demand for financial services, which in turn positively impacts financial development (Robinson, 1952; Demetriades & Hussein, 1996; Panizza, 2012). Third, causality in the finance-growth nexus is bi-directional. The majority of studies (for example, Greenwood & Smith, 1997; Luintel & Khan, 1999; Al-Yousif, 2002) revealed bi-directional relationship between financial development and economic growth. Fourth, no causal relationship between financial development and economic growth is found.

Most previous studies (for instance, Schumpeter, 1912; Robinson, 1960; Greenwood & Jovanovic, 1990; King & Levine, 1993; Greenwood & Smith, 1997; Levine, 2005) predicted a linear relationship between finance and growth. However, few studies (for example, Berthelemy & Varoudakis, 1996; Deidda & Fattouh, 2002; Deidda, 2006) argued that financial development occurs endogenously as the economy reaches a critical threshold of economic development. If the economy is below the threshold level of financial development, then there is no effect on economic growth, while a sizeable effect occurs above the specific threshold level (Huang & Lin, 2009).

The threshold effect may either relate to the level of economic development or with financial development across countries (Bose & Cothren, 1997; Law & Singh, 2014; Samargandi, Fidrmuc, & Ghosh, 2015; Zhu, Asimakopoulos, & Kim, 2020). In particular, higher financial development may not exert a positive impact on economic growth unless a certain level of financial development is reached. Recent studies (such as Law, Azman-Saini, & Ibrahim, 2013; Arcand, Berkes, & Panizza, 2015; and Samargandi, Fidrmuc & Ghosh, 2015) detected that non-linear relationships between financial development and economic growth is dependent on mediating structural factors, including economic institutions.i Likewise, Swami (2017) discovered that the association of financial development with economic growth was moderated by the negative impacts of inflation, interest rate, population dependence, and positive mediated effect of trade openness. Ibrahim and Alagidede (2018) found that the finance-growth relationship is a non-linear and inverted U-shaped. Similarly, Swamy and Dharani (2020) discovered inverted U-shaped relationship between financial development and economic growth with estimated tripping point was at 141% of GDP. They found that surpassing the threshold level results deceleration in economic growth.

Keeping the importance of finance-growth nexus, the Government of Pakistan embarked on a series of financial sector reforms in the early 1990s. The objective of these reforms was to create a level-playing field for the financial institution by eliminating entry barriers and accelerating competition among the financial institutions, removing distortions and financial market’s segmentation, eliminating direct and subsidized credit programs and strengthening the supervisory role of the State Bank of Pakistan (Khan & Khan, 2011; Naveed & Mahmood, 2019). These reforms have changed the financial spectrum. These structural shifts may distort the linear relationship between financial development and economic growth and justify the use of the non-linear methodology to analyze finance-growth nexus. The non-linear relationship suggests that economic growth may respond differently to the level of financial development when it remains below or above the certain threshold level. In other words, changes in financial development policies might influence the level of financial development and economic growth differently in a different state of policy intervention (Deidda & Fattouh, 2002; Demetriades & Law, 2006; Tran & Nguyen, 2020).

Several studies on finance-growth nexus are available in Pakistan (for instance, Khan, Qayyum, & Sheikh, 2005; Naveed & Mahmood, 2019). However, to the best of our knowledge, no study employed the threshold regression approach to examine the impact of financial development on economic growth. The majority of previous studies provided strong positive evidence of linear relationship on finance-growth nexus. However, the proposition of linear relationship between financial development and economic growth is restrictive, especially when policy intervention occurs in the economy (Ibrahim, 2015). Recent empirical literature highlighted the importance of non-linear relationships between financial development and economic growth (Deidda & Fattouh, 2002; Kumar & Paramanik, 2020; Rahman, Khan, & Charfeddine, 2020). However, empirical research on non-linear relationship between financial development and economic growth with respect to Pakistan is scant. Thus, the present study attempts to examine the impact of financial development on economic growth in Pakistan under the threshold modeling framework.

Against the above backdrop, this study contributes to the existing literature by focusing on finance-growth nexus using the threshold model. This model is useful to determine whether too much finance is beneficial (harmful) for economic growth? This question entails much importance for countries like Pakistan where resources are scarce. Secondly, the present study uses broad-based financial development index (FDI) constructed by the International Monetary Fund (2018) as a proxy of financial development, which covers both aspects of the financial development, that is, financial institutions and financial markets. Most importantly, this index captures the financial depth, financial access and financial efficiency of financial institutions and markets. Thus, FDI is the most comprehensive index that captures banks, pension funds, mutual funds, insurance market, debt and securities market and equity market. The findings have potentially important implications for the financial managers and regulators for devising prudent investment and economic growth strategies. Previous studies on Pakistan mainly focused on banking sector variable(s). But this study overcomes the issue of financial structure and focuses on both the financial institutions and financial markets as financial development indicators. We used time-series data to formulate the country-specific policies rather than general information about finance-growth nexus. Besides, this study also provides non-linear estimations of finance-growth nexus in Pakistan to examine the effects of high-level (low-level) financial development on economic growth.

The rest paper is organized as Section 2 reviews relevant literature on finance-growth nexus. Section 3 deals with the model, data, and methodology. Section 4 discusses empirical results, while section 5 recapitulates concluding remarks and outlines policy implications.

2. Literature Review

The academic discussion on finance-growth nexus was started when Schumpeter (1912) recognized the role of finance in economic growth process. He argued that financial development contributes to economic growth through capital accumulation and technological innovations. Afterward, McKinnon (1973) and Shaw (1973) asserted the positive role of financial development in economic growth process. In relation to the finance-growth nexus, Patrick (1966) proposed “stages of development” hypothesis that considers supply-leading and demand-following hypotheses. The supply-leading hypothesis stated that financial development plays an important role to sustain economic growth through pooling of resources, risk management and intermediary functions (Levine, 1997). This hypothesis was tested by several researchers using the panel, cross-sectional and timeseries data and found mixed results. For instance, Luintel and Khan (1999) found significant support for the validity of the supply-leading hypothesis in 10 developing countries. De-Gregorio and Guidotti (1995) detected a positive relationship between financial development and economic growth in cross-sectional data and a negative relationship in panel data for Latin American countries.

High level of financial liberalization and poor banking regulations were the main reason behind the negative relationship. On the other hand, the demand-following hypothesis advocated the unidirectional causality from economic growth to financial development. Robinson (1952) argued that financial development followed the enterprise at the initial stage of financial development. Kuznets (1955) supported this argument and found that the nature of economic cycle significantly affected financial development. Considering the endogenous growth framework, Romer (1986) and Lucas (1988) also argued that financial sector significantly contributed to economic growth through mobilizing savings, efficient allocation of capital resources, minimizing information, monitoring and transaction costs, facilitating exchange of goods and services and diversifying risks. The demand-following hypothesis was acknowledged by many researchers (for example. Khan, Qayyum, & Sheikh, 2005; Ang & McKibbin, 2007; Rehman & Cheema, 2013; Khan, Ahmed, & Bibi, 2018). They concluded that financial development acts as a main engine of economic growth.

One strand of literature identified a bi-directional relationship between finance and growth. For instance, Greenwood and Jovanovic (1990) argued that financial development promotes investment and economic growth, which in turn spurs financial development.

Few studies emphasized bank credit channel and concluded that financial development can boost or deteriorate economic growth depending on the type of bank credit extended (Arestis & Demetriades, 1997; Beck, Buyukkarabacak, Rioja, & Valev, 2012; Sassi & Gasmi, 2014). In particular, Beck, Buyukkarabacak, Rioja, and Valev (2012) argued that positive impact of financial development on economic growth is mainly determined by enterprise credit rather than consumer credit. Another strand of the literature concluded no relationship between financial development and economic growth. For example, Lucas (1988) argued that financial development is not a determinant of economic growth because as the economy reached a steady-state level, excess capital has no significant impact on economic growth. Many researchers (for example, Kar, Nazlıoglu, & Agir, 2011; Ali, 2014; Ibrahim & Alagidede, 2018) concluded that the impact of financial development on economic growth in developing countries is inconclusive.

The empirical literature provides mixed delineation with respect to the impact of financial development on economic growth. For instance, Herwartz and Walle (2014) and Pradhan, Arvin, and Bahmani (2018) found positive relationship between financial development and economic growth. On the other hand, Narayan and Narayan (2013) and Ductor and Grechyna (2015) detected a weak or negative relationship between financial development and economic growth. Chong, Mody and Sandoval (2017) observed that negative relationship between financial development and economic growth has become stronger since 1990 in Europe, which was consistent with the fact that growth of financial system declined economic growth. Findings by Demetriades and Rousseau (2017) indicated that bank regulations and banking supervision exerted a significant effect on financegrowth relationship. Naveed and Mahmood (2019) found a positive and significant impact of internal financial liberalization on economic growth in the long-run, while said relationship turned to be negative in the short-run.

Recent studies indicated that higher financial development may strengthen economic growth before a certain threshold of financial development is reached (Samargandi, Fidrmuc, & Ghosh, 2015). Law and Singh (2014) concluded that finance is good for economic growth only up to a certain limit, and more finance beyond a limit may not be good for the economy. In the same vein, few concluded (Deidda & Fattouh, 2002; Arcand, Berkes, & Panizza, 2015) that finance exerted a negative impact on economic growth when the level of financial development remains below a certain threshold level. Samargandi, Fidrmuc, and Ghosh (2015) detected an inverted U-shaped relationship between financial development and economic growth in 52 middle-income countries. Alaabed and Masih (2016) investigated the finance-growth threshold for the Malaysian economy and found that expansion of credit has negative impact on economic growth. More recently, Zhu, Asimakopoulos, and Kim (2020) investigated 50 countries to address the question of whether too much finance is effective in finance and innovation-led growth nexus. They found small or even insignificant impact of innovation in the countries having higher level of financial development. Besides, marginal effect of innovation on economic growth is found negatively related to financial development. Similarly, Aluko and Ibrahim (2020) investigated 28 SubSaharan African countries to find the threshold between institutions and finance-growth nexus. They found distinct behavior of institutions in finance-growth relationship. They used different institutional proxies as threshold variable and found that when International Country Risk Guide (ICRG) dataset was used the financial development does not spur economic growth below the optimal level of institutions and vice-versa. Surprisingly, they found that growth spurring effects of finance are higher for such countries having low institutional quality than high institutional quality.

With respect to Pakistan, the majority of studies (for instance, Khan, Qayyum, & Sheikh, 2005; Tahir, 2008; Khan, 2008; Jalil & Ma, 2008; Rehman & Cheema, 2013; Naveed & Mahmood, 2019) used linear modeling technique to investigate finance-growth nexus. However, these studies ignored the asymmetric relationship, while investigating finance-growth nexus. Only Rahman, Khan, and Charfeddine (2020) confirmed that the behavior of financial development is heterogeneous in pre-and post-reforms periods. However, they ignored the possibility of threshold existence in financegrowth relationship.

From the above literature survey, we deduced that most of the empirical work used linear models to predict the finance-growth relationship in Pakistan. However, Maki (2008) showed that using linear models to interpret nonlinear relationships may lead to poor inferences. Since the financial sector of Pakistan adopted financial reforms in the 1990s, it is expected that economic growth does not respond monotonically in the pre-and post-reform periods. Therefore, this study considers non-linear aspect of finance-growth nexus in Pakistan using the threshold modeling approach.

3. Model, Data, And Methodology

The theoretical framework of this study stems from endogenous growth theory. Several empirical studies highlighted that financial development affects economic growth through capital accumulation and technological innovations. Our modeling approach is based on endogenous growth theories propounded by Lucas (1988), Romer (1986) and Pagano (1993). Following Ang (2011) and Chong, Mody, and Sandoval (2017), we consider following aggregate production function:

\(Y_{t}=A_{t} K_{t}^{\alpha 1} L_{t}^{\alpha 2} e^{s t}\)       (1)

Where, Yt is real GDP at time t proxied for economic growth, At is total factor productivity (TFP) at time t, Kt is physical capital at time t, Lt is employed labor force at time t, α1 and α2 are production elasticities with respect to physical capital and employed labor force respectively, while εt is error term. The log-linear form of equation (1) can be written as:

\(\operatorname{LnY}_{t}=\operatorname{LnA}_{t}+\alpha 1 \ln K_{t}+\alpha 2 \operatorname{LnL}_{t}+\varepsilon_{t}\)       (2)

Assume that total factor of production (At) is determined by financial sector development, consumer price index, government expenditure as a percentage of GDP and trade openness. Following Anwar and Sun (2011), we specify TFP determinants as follows:

\(\begin{aligned} L n A_{t} &=\gamma_{0}+\gamma_{1} L n F D_{t}+\gamma_{2} L n C P I_{t} \\ &+\gamma_{3} L n G E X_{t}+\gamma_{4} L n T O_{t} \end{aligned}\)       (3)

Substituting equation (3) into equation (2), we get the following equation.

\(\begin{aligned} \operatorname{Ln} Y_{t}=& \beta_{0}+\beta_{1} \operatorname{Ln} F D_{t}+\beta_{2} \operatorname{Ln} K_{t}+\beta_{3} \operatorname{Ln} L_{t} \\ &+\beta_{4} \operatorname{LnT} O_{t}+\beta_{5} \operatorname{Ln} G E X_{t}+\beta_{6} I N F_{t}+\varepsilon_{t} \end{aligned}\)       (4)

Where FDt measures financial development at time t, CPIt is inflation rate at time t, GEXt is government expenditures relative to GDP at time t and TOt is trade openness relative to GDP at time t.

In equation (5), FD  is likely to have a positive effect on economic growth since it facilitates saving and investment decisions. Besides, financial sector also facilitates investment opportunities in equity market. Other sectors such as insurance sector, mutual fund and debt and securities market also contribute to the financial sector development. Trade openness (TOt) which is measured by the sum of exports and imports as a percentage of GDP is expected to exert positive impact on TFP and hence economic growth. However, there is also possibility of negative effect of trade openness on TFP and economic growth in case of developing countries. Trade openness is expected to behave negatively with economic growth in Pakistan owing to major share of exports relative to imports. The impact of GEXt on economic growth in developing countries is generally negative due to bureaucratic inefficiency. Durham (2004) argued that public spending financed through tax increase can deteriorate economic performance due to input costs increase, which in turn exerted a negative impact on economic growth. However, we expect positive signs of government expenditures due to bureaucratic reforms in Pakistan. An increase in INFt rises macroeconomic uncertainty, which is expected to exert a negative impact on TFP, and hence economic growth. Following Ibrahim and Alagidede (2018), we can rewrite equation (4) as:

\(\ln Y_{t}=\beta_{0}+\beta_{1} L n F D_{t}+\delta_{i} \operatorname{Ln} X_{t}+\varepsilon_{t}\)       (5)

Where Xt is a vector of non-financial variables such as physical capital proxied by the gross fixed capital formation relative to GDP, labor force, inflation rate, trade openness and government consumption expenditure relative to GDP. The main objective of this study is to examine the non-linear impact of finance on growth using the threshold model. In non-linear setup, the response of financial development to economic growth is expected to be different in different regimes.

3.1. Data

The present study uses annual data for the period 1980- 2017. The World Bank’s World Development Indicators (WDI) and International Monetary Fund (IMF) are the main data sources. In this study, we used the FDI developed by Svirydzenka (2016) and updated by IMF since Adu, Marbuah and Mensah (2013) argued that a single proxy of financial development is not enough to capture the whole impact of financial development on macroeconomic variables. The FDI captures the access, depth, and efficiency of the financial institutions and financial markets. Financial institutions include banking and insurance sector, while financial markets include equity and bond markets, and other nonbanking financial institutions. Thus, FDI is broader in extent that captures wide-ranging aspects of financial sector. Figure 1 depicts the trend of FDI along with its two components, that is, financial institution index (FII) and financial market index (FMI) over the period 1980 to 2017.

Figure 1: Trend of Financial development index

It is evident from Figure 1 that the contribution of FMI towards FDI was negligible till 1996, while FII was main contributor from 1980-1996. However, this trend reversed after 1996 when financial markets in Pakistan were operating under liberal macroeconomic environment. After 1996, FMI surpassed FII and peaked in 2007, thereafter contribution of FMI followed declining trend and reached its minimum level in 2014. The spurts and reversals were observed in FDI due to the adoption of financial liberalization policies. After 2007, the FDI is showing decreasing trend which indicating backtrack of financial sector reforms due to global financial crisis of 2007-08 and European debt crisis of 2011. This indicates that the role of FMI in enhancing FDI is crucial, therefore, more liberalization of financial markets may boost overall financial development in Pakistan.

The real GDP (Yt) is used as a proxy of economic growth following Samargandi, Fidrmuc, and Ghosh (2015). Physical capital (Kt) is used to measure domestic investment level by utilizing the information on gross fixed capital formation as a percentage of GDP. The employed labor force is used as proxy of labor. Inflation (INFt) is calculated as the annual percentage change in the consumer price index and it captures macroeconomic stability. Trade openness represents the significance of international factors in affecting economic activities (Huchet-Bourdon, Mouel & Vijil, 2018). Trade openness TOt is calculated as the sum of exports and imports as a percentage of GDP. Government expenditure as a percentage of GDP (GEX) is used to measure the size of government and bureaucratic efficiency. It also accounts for investment in physical capital, which may significantly affect economic growth.

Table 1 reports summary statistics of the variables. The mean value of real GDP was 29.37. The average value of FDI was 0.22, indicating that financial development contributes positively to economic growth. Similarly, mean values of other variables are also found positive. The mean value of the labor force is relatively higher than physical capital showing that Pakistan is a labor-intensive country and the role of labor is relatively larger than physical capital. Statistics also indicate that the standard deviation of inflation was 3.89, indicating high volatility in consumer prices, which in turn increases macroeconomic uncertainty. Additionally, standard deviation of financial development was observed to be 0.08, which reveals that financial development is least volatile than other variables under investigation. The trade openness and inflation rate have relatively heavier tails as compared to other variables.

Table 1: Summary statistics

OTGHEU_2020_v7n8_161_t0001.png 이미지

Table 2 gives pair-wise correlation among the variables. The real GDP has negative correlation with physical capital, trade openness and government expenditures, whereas all other variables have positive correlation with real GDP. Interestingly, FDI has positive correlation with real GDP, which reveals that better quality financial system enhances economic growth. Labor force and physical capital have highest correlation with real GDP, while FDI has negative correlation with physical capital, trade openness, government expenditures and inflation rate.

Note: ***, ** and * indicates significant at 1%, 5% and 10% level of significance based on t-statistics.​​​​​​​

To examine the non-linearity between finance and growth, we employed the BDS (Brock, Dechert, & Scheinkman, 1987) test (see Table 3). The BDS test is useful in detecting non-linearity under the null hypothesis that residuals are independent and identically distributed (iid).

Table 3: Results of BDS Test

OTGHEU_2020_v7n8_161_t0003.png 이미지

Note: ***indicates significance at 1% level of significance. P-values based on bootstrap (100,000 replications).​​​​​​​

BDS test confirms that finance-growth nexus is nonlinear since selected dimensions are significant at 1% level of significance. Therefore, data suggest that the use of linear statistical techniques may provide spurious results. Hence, non-linear technique may provide better estimates as compared to linear estimation method. To this end, threshold regression model provides useful information with respect to the impact of low-FD and high-FD on economic growth.

3.2. Threshold Model

The vast literature on finance-growth nexus can be characterized by the inconclusiveness of empirical findings. This inconclusiveness may arise from non-linear relationship between finance and growth. This study hypothesizes that repressive and liberal financial sector may have differing effects on economic growth depending on whether financial development surpasses a critical threshold level. For this reason, threshold model developed by Hansen (1999) is employed, which allows non-linear relationship between dependent and independent variables, which are determined by the threshold level (Bilman & Karaoglan, 2020). The threshold model is superior as compared to other models because it not only computes nonlinear function but also facilitates estimation of threshold value rather than fixing them at any arbitrary value (Swamy & Dharani, 2020). Following Hansen and Seo (2002), functional form of equation (5) in terms of threshold regression model can be expressed as:

\(Y_{t}, q_{t}, X_{t} ; 1 \leq t \leq T\)       (6)

Where Yt is dependent variable at time t, qt is a threshold variable, and Xt is a set of variables hypothesized to affect economic growth. The structural form of equation (6) for a single threshold can be written as:

\(Y_{t}=\left\{\begin{array}{l} \beta_{0}+\beta_{1} F D_{t}+\delta_{i} X_{t}+u_{t} \text { if } F D_{t} \leq \lambda \\ \beta_{0}+\beta_{2} F D_{t}+\delta_{i} X_{t}+u_{t} \text { if } F D_{t}>\lambda \end{array}\right.\)       (7)

Where β0 is intercept term, ut is error term which is assumed to be independent and identically distributed (iid), λ is threshold value, while FDt is regime-dependent regressor. Since the focus of this study is to examine the effects of FDt on economic growth conditional on FDt. Therefore, the effect of FDt on economic growth can be investigated under two possible cases: when FDt is below or above the estimated threshold parameter (λ), an estimated value of FDt that splits sample into low-FDt and high-FDt regimes. After estimating threshold parameter ˆ λ, we estimated regimedependent coefficients β1 and β2, which coincides with lowFDt and high-FDt regimes, respectively (Tran, 2018). Once threshold value is identified, we can test significance of threshold effect under null hypothesis of no threshold effect (H0 : β1 = β2) against alternative hypothesis of one threshold (H1 : β1 ≠ β2) using Likelihood ratio test. If F-statistic is greater than critical value, the null of no threshold is rejected. To check robustness of threshold regression model, we employed quantile regression model.

3.3. Quantile Regression

The quantile regression is popular approach for conditional distribution instead of conditional mean distribution, which was presented by Koenker and Bassett (1978). We employed quantile regression with 0.25, 0.50, and 0.75 quantiles of conditional distribution. The quantile regression is based on minimizing of sum of squared residuals which estimate conditional mean function.

The quantile regression is useful for robustness as compared to other methods. Andini and Andini (2014) argued that quantile regression is useful to examine the changing shape and shifting location of conditional distribution. Additionally, estimates of quantile regression are more robust in the presence of outliers. Likewise, Mello and Perrelli (2003) argued that quantile regression provides useful information that how macroeconomic variables react to changes in policy variables. This study uses three different quantiles of financial development index to examine how economic growth responds to various quantiles of financial development. Furthermore, we examine the way by which finance-growth nexus differs at tail of conditional distribution by considering graphs corresponding to different quantile between 10th and the 90th.

4. Empirical Results

We consider FDt as regime-dependent variable, while rest variables are treated as regime-independent. Because of small sample size, we assume only two-regime threshold model that coincides with the low-FDt and high-FDt regime. Intuitively, two-regime model based on single threshold may perform better and easy to elaborate empirical findings. We have running several regressions using Ordinary Least Squares (OLS) on equation (7) to estimate threshold parameter. Afterward, we obtained the sum of squares residuals S(λ) and choose that threshold value which makes the S(λ) smallest, that is, . λˆ = arg min (λ). Thus, there exists a single threshold and the computed threshold parameter λ ˆ is 0.151. The computed threshold value (0.151) will split the financial development data into two subsamples. The computed F-statistic is 22.29 which is higher than critical value of 8.58, indicating the rejection of null hypothesis of no threshold.

The results of finance-growth nexus based on the threshold estimation are reported in Table 4. It can be seen from results that in low-FDt regime financial development has a negative and statistically significant effect on economic growth if it is less than the threshold value of 0.151. The estimated threshold value of 0.151 is fairly low in finance-growth literature as compared to earlier studies. The previous studies have estimated finance-growth threshold value between 0.53 and 1.00. To this end, using a panel of 87 countries Law and Singh (2014) estimated threshold value of 0.88 and 0.91 respectively for private sector credit to GDP and liquid liabilities to GDP. Likewise, Samargandi, , Fidrmuc, and Ghosh (2015) investigated 52 middle-income counties and found 0.92 as financial development threshold value. Whereas Zhu, Asimakopoulos, and Kim (2020) found the values of threshold as 0.39 when used domestic credit variable, 0.44 for private credit and banking credit, and 0.61 when used liquidity as proxy for financial development. The lower value of threshold in our case may be due to a single country estimation, small size of financial as well as real sector and relatively low quality institutions.

Note: ***, ** and * denotes significant at %, 5% and 10% level of significance. Figure in [.] are p-values.​​​​​​​

The coefficient of financial development in low-FDt regime is -0.74 which suggests that a unit-percentage point increase in financial development would reduce economic growth by 0.74%. On the other hand, the impact of financial development on economic growth is turned to be positive and statistically significant when it surpasses threshold value of 0.151 in high-FDt regime. The result reveals that economic growth increases by 0.38% in response to a unit-percentage point increase in the level of financial development in high-FDt regime. Thus, differential impact of finance on growth in both regimes confirms U-shaped impact of financial development on economic growth in Pakistan. The magnitude associated with FDt pinpoints that negative impact of financial development in low-FDt regime is more severe than benefit of high-FDt regime. This suggests that Pakistan must attain the financial development above the threshold level for an effective role in economic growth.

These findings are in line with empirical literature that as level of financial sector deteriorates, economies of scale benefit from the lower costs and higher return of capital, thereby slowing economic growth. On the other hand, greater level of financial development boosts economic growth. These results are inconsistent with Khan, Qayyum, and Sheikh (2005), Khan (2008), and Naveed and Mahmood (2019) in case of Pakistan. Our results also differ from Law and Singh (2014), Arcand, Berkes, and Panizza (2015), and Ibrahim and Alagidede (2018). However, our findings are consistent with Deidda and Fattouh (2002), Henderson, Papageorgiou, and Parmeter (2013), Ruiz (2018), and Rahman, Khan, and Charfeddine (2020). These studies reported a higher impact of financial development on economic growth according to the income levels in various economies. The main reason could be that financial development directed towards investment activities promotes economic growth, but consumption loans move towards opposite direction (Hung, 2009).

Among non-threshold variables, physical capital, labor force and government expenditure exerts positive and significant impact on economic growth. The results indicate that real GDP would increase by 0.28% and 1.56% in response to a 1% increase in physical capital and labor force. Particularly, increase in physical capital may increases productive capacity of goods and services at lower cost, which leads higher production hence higher economic growth. Likewise, government expenditure also exerts positive effect on economic growth. The result indicates that a 1% increase in government spending would increase real GDP by 0.26%. This implies that government expenditure on public services and investment in infrastructure significantly enhances economic growth. Although, government expenditures are enhancing economic growth, but small magnitude (0.26) signals bureaucrats for better and productive use of government expenditures. With efficient bureaucratic role, government expenditures can further contribute to economic growth in Pakistan. The result also indicates that inflation rate and trade openness exert insignificant negative impact on real GDP.

4.1. The Quantile Regression

To check the robustness of threshold results and to further understand behavior of finance-growth relationship, we employed quantile regression technique to examine the response of economic growth to variant levels of financial development. To this end, we used 0.25th, 0.50th and 0.75th quantile of real GDP distribution. Table 5 reports results of the whole period, 25th and 75th quantiles. The 25th quantile of real GDP distribution representing low-growth regime, while 75th quantile showing high-growth regime.

Note: ***, ** and * indicates significant at 1%, 5% and 10% level of significance. Sparsity function is computed using kernel method. Results are robust to other methods such as bootstrap or Siddiqui.​​​​​​​

Table 5 shows that impact of FDI on economic growth is quite different between low-growth and high-growth regime. This can be seen from coefficient magnitude, sign and significance of each variables. For example, estimated 25th quantile coefficient of FDI is eight times higher than that of the 75th quantile. The result indicates that economic growth would increases by 0.80% in response to a unit percentage point increase in FDI when 25th quantile is considered, whereas a one-percentage-point increase in FDI leads to a 0.10% increase in economic growth when the 75th quantile is considered. Besides, the major difference in coefficient of FDI is observed for 25th, 50th and 75th quantiles. The reason may be sensitivity of financial sector with respect to level of economic growth. This heterogeneous response of economic growth to FDI confirms the findings of the threshold regression model. The values of Pseudo R2 confirm that quantile model best fits the data. The effect of FDI on economic growth at different quantiles is depicted in Figure 2.

Figure 2: Impact of FDI on real GDP (95% confidence interval)​​​​​​​

Figure 2 shows that the impact of FDI on economic growth remains constant up to 60th quantile. Afterward, impact of FDI dropped sharply by about 10% until the 75th quantile. Thereafter, the impact falls slowly as economic growth increases. Interestingly, we observed that decline in the impact of FDI on real GDP is lesser for highest quantile than lowest quantile. This means that the impact of FDI on economic growth is higher in low-growth regime than that of high growth regime.

The physical capital and labor force appeared to be important variables in influencing economic growth in the 75th quantile. Inflation rate and trade openness exerts insignificant impact on economic growth across all the quantiles. However, government expenditures observed to be significant in 25th quantile.

5. Conclusion and Policy Implication

This study provides new insights on the non-linear finance-growth relationship in Pakistan using threshold model during 1980-2017. The result reveals two-regime dependent effects of financial development on economic growth. The said impact is found to be negative when financial development lies below the threshold value of 0.151 in the low-FDt regime. However, financial development significantly contributes to economic growth when level of financial development surpasses the threshold level of 0.151 in the high-FDt regime. This finding indicates that financial development is ineffective in promoting economic growth if it is less than the threshold value. However, when financial development is above the threshold value, economic growth reacts positively to financial development. These findings support the hypothesis that the relationship between finance and growth is inverted U-shaped. The negative impact of FD in low-FD regime is more harmful than benefits of positive impact in high-FD regime. Therefore, Pakistan may maintain minimum threshold level of financial development for its positive contribution in economic growth. Additionally, quantile regression results also confirms heterogeneous response of economic growth to financial development between the 25th and 75th quantiles. The physical capital, labor force and government expenditure appear as important factors enhancing economic growth.
​​​​​​​

The key policy implications are: financial development exerts asymmetric impact on economic growth. This implies that financial development partially spurs economic growth. It is well documented in the literature that underdeveloped financial sector may be associated with high transaction costs, rigidities, and sub-optimal allocation of resources, which in turn adversely affects overall economic growth. However, as financial development surges above the threshold level, economic growth increases. It means that countries with high financial development may enjoy higher economic growth. In Pakistan, our results reveal that financial development behaves negatively in lowfinancial development regime, therefore, revamping of financial sector policies are required. In order to improve the efficiency of financial sector, policymakers may design strategies to enhance credit allocation, strengthen regulatory and institutional frameworks to make it possible for the financial sector to generate positive impacts on economic growth. Besides financial development, physical capital, labor force, and government expenditure are key variables contributing to economic growth.

Although this study provides important insights on finance-growth nexus using the threshold model. However, it would be more insightful to investigate region-specific thresholds in the finance-growth nexus. It would also be more interesting to investigate the responses of economic growth to domestic financial development using the regimeswitching model. We leave this possibility for future research.
