I constructed the 2003 Korean 'social accounting matrix'(SAM) to analyze the multipliers of total demand for each economic activity. I find that the relative magnitude of the influence of the welfare policy to the national economy measured by input-output production multipliers tends to be underestimated compared to SAM multipliers. This is because the total demand multipliers of SAM include the private sector effects, which is not considered in the input-output model. The result also support that income inflows in public service areas including education, health and social work, generate gains in the relative income of households.

This study derived production-production multipliers using a regional input-output table and estimated the induced effect of aggregates through the non-metallic minerals sector and the concrete products sector. In deriving the induced effect of aggregates, it is difficult to use the regional input-output table due to the sector classification problem. This study analyzed the non-metallic mineral sector, including aggregates, as aggregates sector, and the concrete products sector, which uses most of the aggregate production. By analyzing this, we attempted to alleviate difficulties caused by sector classification restrictions. In the process of estimating the induced effect, it was assumed that there was a decrease in aggregate production, and in the process of analyzing the concrete products sector, the effect of the decrease in concrete product production due to the decrease in aggregate production, that is, the decrease in production of one unit of aggregate was 0.8511 in the concrete product sector. The analysis was conducted on the premise of a decrease in unit production. Inducing effects within and between regions were calculated for the 17 metropolitan cities and provinces classified by the regional input-output table. The employment effect was also calculated, assuming a 10% production decrease to show differences according to the size of the aggregate and concrete product sectors in each region.

The purpose of this study is to establish evaluation model that can explain marginal effects of baseball players of Korean Baseball Organization (KBO) on their team winnings in terms of productivity. We proposed econometric model with using variables that are provided from official homepage of KBO to overcome the complexity of mainly used productivity index: wins above replacement (WAR). Also, compare to the previous studies such as Scully(1974) or Krautmann(1999) that using limited indices of baseball stats, this study included 61 indices that are provided from official homepage of KBO. We estimated regression based WAR(RBWAR) by conducting panel regression with each team's statistics data of 2002 to 2014. As a results, RBWAR shows 0.869 correlation coefficient for batters and 0.882 for pitchers with WAR in 2014 that can be concluded that two indices shows similar results. From the results of estimation, we analyze the relationship between productivity and actual contract of free agent players in 2015 and it showed that teams have contracted reasonably.

This study aimed to estimate the economic impact of the '2011 Seoul Motor Show' using a direct survey-based regional input-output(I-O) model. Based on the regional I-O table, Exhibition multipliers were derived with respect to output, income, employment, value-added and indirect tax. Attendees' survey was conducted to estimate per capita expenditure. The results of this study indicated that all attendees of '2011 Seoul Motor Show' generated 53.1 billion Won of output impact, 11.7 billion Won of income impact, 24.1 billion Won of Value-added impact, 2.6 billion Won of tax impact, and 1,030 part-time and full-time jobs throughout direct and indirect effects. Another result of this study was that output multiplier of the exhibition industry was similar with other industries, however, income, employment and value-added multipliers were relatively larger than those of other industries.

Input-output(I-O) analysis is now widely used to examine the economic impact of tourism. The study aims to demonstrate the impact of agri-tourism development project on local development in terms of income and employment. Based on the I-O transactions tables developed by Bank of Korea (2011), rural tourism related sectoral multipliers were derived with respect to output, income, employment, and value-added tax. The results of the I-O model indicate that in 2011, rural tourism development generated 1,387 billion Won of output impact, 287 billion Won of income impact, 275 billion Won of value-added impact, and 41,127 full-time jobs, respectively throughout direct, indirect, and induced effects. In particular, the restaurant sector had relative higher output and employment multipliers as compared to other industries, whereas they had lower multipliers of income and value-added than any other industries. The findings imply that the restaurant sector was relatively labor-intensive industry, generating high impact of employment effects.

Utilization of cultural contents is more and more increasing as it is believed to improve local problems and provide historical values. This kind of business is positive in terms of the fact that it attracts visitors into local areas and activate local commercial areas. Under this trend, the construction of specialized streets is required to be approached with first priority to solve problems of cities. So to speak, it's more important to solve intrinsic problems found in local communities and then approach cultural contents step-by-step rather than constructing new spaces with first priority. Moreover, cultural contents should accompany economic aspects which result in local community-friendly and sympathetically concentrated values. Under this sentiment, the efforts to suggest economic ripple effects for government local government's businesses using cultural contents are very important. This study analyzed how much economic ripple effects is yielded by reflecting cultural contents. As the result of analysis, specialized street with cultural contents applied are proved to be more concentrated on multiplier of expediting employment, income and tax and tourism industry than service industry. On the contrary to this, service industry showed more concentrated multiplier of expediting production, income, added values and chain reaction effect (coefficients for influence and sensitivity for front and rear side of tourism industry. Based on these results, construction of specialized streets with cultural contents applied is proved to help synergy effects for local economy.

The inter-industrial inducement effects of the Korean railway services on the output, value-added, and imports of 383 industrial sectors of the Korean economy have been computed by the input-output analysis technique utilizing the '2013 Input-Output Statistics', which was published most recently in December 2015 by the Bank of Korea. The research results are, then, compared and contrasted with the former research results with the '2003 Input-0utput Statistics', which were published in the Journal of the Korean Society for Railway, August, 2008. The economic inducement effects computed in this study are as follows. The Korean railway service industry produced \5,841 billion worth of passenger and freight railroad services in the year 2013, and it induced \8,511 billion worth of output, \84 billion worth of value-added, and \1,050 billion worth of imports for Korean industry as a whole.; the production inducement multiplier, value-added multiplier, and imports inducement multiplier of 2013 results are shown to be quite different from 2003 multipliers.; it has been shown that it is necessary to utilize the most recent Input-Output Statistics for the computation of the most recent inter-industrial analysis.

The paper is basically designed to investigate how regional consumption affects to regional income in Korea by introducing a model with panel cointegration, rational expectation and FM-OLS cointegration methodology. Empirical evidence reveals that the regional income could be stimulated by manipulating the regional consumption due to the fact that current regional consumption and first-lagged regional income are positively related to the level of regional income. Although there exists a possibility to increase the regional income which is associated with a spending multiplier in the group of regions with highly calculated MPC, but not in the groups of regions with middle and low calculated MPCs. To this end, it could be tentatively concluded that market-oriented system should be implemented elaborately to enable that the spending multipliers are appropriately operated in these two groups.

원자력 발전 산업의 산업연관분석 결과에 의하면, 원자력 발전의 운영을 통하여 1993년에 국내총산출액 및 국내총생산의 0.5%를 생산하고 있는 것으로 나타났다 원자력 발전 산업의 생산물인 전력은 다른 산업의 생산활동을 위한 중간재로서 활발히 이용되고 있는 바, 이에 대한 지표인 중간수요비 즉 전방연관효과가 전체 산업평균 보다 높은 것으로 나타났다. 반면에 원자력 발전 산업 자체의 생산활동에서 필요로 하는 중간재에 대한 수요 즉, 후방연관효과는 전체 산업평균 보다 상당히 낮은 것으로 나타났다. 한편 원자력 발전 산업의 부가가치율은 다른 발전 산업 중에서 가장 높아서 경쟁관계에 있는 화력 발전산업에 비해 2배 이상의 부가가치를 창출하는 것으로 분석되었다. 원자력 건설 산업의 경제활동이 국민경제에 미치는 파급효과를 살펴보면 생산유발계수가 정부투자와 민간투자에 비해 높아 생산파급효과가 상대적으로 더 큰 것을 알 수 있다 그러나 수입유발계수는 정부투자와 민간투자에 비해 다소 높은 것으로 나타났다.

자원 및 환경이 경제에 미치는 영향이 큼에도 불구하고 경제-환경의 상관관계를 분석하는 방법은 아직 초보 단계에 있다. 본 연구에서는 UN, 세계은행, 멕시코 정부가 구축한 환경계정(環境計定)을 한 국가의 경제상태를 사회계정에 도입한 후, 환경(環境)-사회계정(社會計定)(ESAM) 행렬을 구축하고, Pyatt와 Round의 분할 행렬 방법에 의해서 직 간접 파급승수 효과를 측정하여, 환경관련 외생변수가 경제변수에 미치는 효과를 분석하였다. 분할 행렬 분석 결과, 농업관련 외생변수에 변화가 있으면 제조업 부문과 상업부문, 민간 서비스부문(금융, 보험, 부동산)이 가장 크게 영향을 받는 것으로 나타났다. 또한 레온티에프의 승수효과와 유사한 전이효과(轉移效果)는 순수한 간접효과인 순환효과의 상쇄로 인해 기존의 산업 연관분석에 의존한 분석은 경제와 환경의 관계를 과대추정할 수 도 있다는 것이다. 자본 투자가 5% 감소할 경우, 경제 전 부문에 상당한 영향을 준 것으로 나타났으며 생산부문에서는 임업, 건설업이 가장 영향을 받으며, 환경부문에서는 토양의 침식으로 인한 환경서비스의 감소가 가장 크게 영향을 받는 것으로 추정되었고 수산자원 또한 많은 영향을 받는 것으로 나타났다.
