The study examines economic and environmental impacts of mass tourism on regional tourism destinations, particularly the establishment of "Ten New Bali", in Indonesia. The sample is restricted to the period of time in which annual data is available and comparable among variables from 1980 to 2015 (36 observations). All of the time series data was collected and retrieved from the World Development Indicator database published by the World Bank. This study applies cointegrating regression analysis using the fully modified OLS, canonical cointegrating regression, and dynamic OLS. The results of the study suggest that 1) there is a long-run equilibrium relationship between tourism receipts, environmental degradation and economic growth in Indonesia, 2) tourism growth and agriculture land growth are positively related to an increase of total output in the short-run in Indonesia, and 3) arable land is significant at the 0.01 level, but forest rents and CO2 from transport are not significant in the short-run in Indonesia. The results confirm that arable land is negatively related to an increase of total output in Indonesia. That is, when tourism growth in the economy is getting realized it shows that the environmental degradation increases greatly in inverse in the model, eventually negative impacts to the environment.

Purpose - The objective of the paper is to explain both the price sensitivity of international tourists to South Korea and the price sensitivity of Korean tourists to international travel. The study examines long-run equilibrium relationships and Granger causal relationships between foreign exchange rates and inbound and outbound tourism demand in South Korea. Research design/ data / methodology - The study employs monthly time series data from January 1990 to September 2010. The paper examines the long-run equilibrium relationship using the Johansen cointegration test approach after unit root tests. The short-run Granger causality was tested using the vector error correction model with the Wald test. Results - Hypothesis 1 testing whether there is a long-run equilibrium relationship between exchange rates, inbound and outbound tourism demand is supported. Hypothesis 2 testing whether exchange rates lead to a change in touristarrivals and expenditure is not supported. Hypothesis 3 testing whether exchange rates lead to a change in tourist departures and expenditure is supported. Conclusions - The findings of this study show that the impacts of tourism price competitiveness are changing quite significantly with regard to destination competitiveness. In other words, the elasticity of tourism price over tourism demand has been moderated.

This research aims to investigate the determinants of real effective exchange rate in emerging ASEAN countries, including Indonesia, Malaysia, Philippines, Thailand, and Vietnam. The research was conducted by using quarterly time series data set from 1980Q1 to 2020Q3. Cointegration and the error correction model (ECM) methods were applied to test the long run and short run relationship of the real effective exchange rate and its determinants. The results indicate that the ratio of foreign direct investment to GDP and the government spending have significantly positive impact on real effective exchange rate in the Emerging ASEAN countries. The trade opening had influencing real effective exchange rate in most the Emerging ASEAN countries, except Vietnam. In addition, the international reserve (INR) had significant long-run impacts variables on real effective exchange rate in Malaysia, Thailand and Vietnam. In the short run equilibrium, the error collection term suggest that Indonesia and Malaysia are the fastest speed adjustment to equilibrium. In addition, the term of trade influence the real effective exchange rate in Indonesia, Malaysia, and the Philippines but it is not in Thailand and Vietnam. However, FDI is a major factor of the real effective exchange rate in Vietnam, but not for other countries.

The paper aims to examine the association between information and communication technology (ICT), economic growth and population health based on health production model in Malaysia. This theoretical health production function is represented as follows: where the output is an individual health outcome, and the inputs are determinants of health, such as income, education, health care costs, medical facilities, the environment, and lifestyle. The development of information and communication technologies are represented as of mobile cellular subscriptions (per 100) and fixed telephone subscriptions (100) using time series data from 1993-2017 from the World Bank database. Using the bound testing technique of cointegration, this study finds that ICT affects population health significantly and positively in the long- and short-run. This is because ICT inclusion improves human health and longevity. Whereas, economic growth has no significant impact on the population's health both in the short- and long-run. The findings indicate that a weak global economy affects Malaysia's economic growth and reduces the health expenditure per capita. The results of this study suggest that policymakers must develop policies that improves public health by increasing health literacy, disseminating health information and facilitating medical facilities. This study also suggests that health care systems should to concentrate on digital inclusion.

2차 에너지인 전력은 다양한 연료를 발전원으로 하고 있기 때문에, 전력에 대한 수요는 에너지 각 부문에 적지 않은 영향을 미친다. 이에 본 논문에서는 전력수요함수를 추정하여 가격탄력성 및 소득탄력성에 대한 정량적 정보를 도출하고자 한다. 이를 위해 1991년부터 2014년까지의 연간 시계열 자료를 이용하되, 탄력성을 단기와 장기를 구분하여 추정할 수 있는 내생시차변수모형을 적용한다. 종속변수로는 연간 전력수요, 독립변수로는 상수항, 전력실질가격, 실질 국내총생산의 3가지를 이용한다. 분석결과 단기 가격탄력성 및 소득탄력성은 각각 -0.142 및 0.866으로 추정되었으며 유의수준 5%에서 통계적으로 유의하다. 즉 전력수요는 단기적인 관점에서 가격 변화에 대해 비탄력적임과 동시에 소득 변화에 대해서도 비탄력적이다. 장기 가격탄력성 및 소득탄력성을 추정한 결과를 살펴보면 각각 -0.210 및 1.287이며 이 값은 유의수준 5%에서 통계적으로 유의하다. 장기적인 관점에서 보더라도 전력수요는 가격 변화에 대해 여전히 비탄력적인 반면에, 소득 변화에 대해서는 전력수요가 탄력적으로 변한다. 따라서 가격정책 위주의 수요관리정책은 단기 및 장기 모두 효과가 제한적이며, 향후 예상되는 소득 증가에 기인하는 전력수요의 증가는 단기보다는 장기에 보다 두드러질 것으로 예상된다.

Purpose - This research examines the short-run and long-run effect of external shocks (oil price and exchange rate) on domestic food price in Indonesia. Research design, data, and methodology - Three variables are used in this research. The variables are food price index, Rupiah's exchange rate of Indonesia, and crude oil price from 1998 until 2015 using Vector Error Correction Model (VECM). Results - The increasing of oil price and the depreciation of Rupiah's rate push the domestic food price in long-run, but do not impact significantly in short- term. The response of food price to oil prices shock and exchange rate shock are positive and persistent throughout the entire sample period. The exchange rate and oil price shocks have a small proportion explaining for the fluctuations of food price index but increasing over time. Conclusions - The policymaker should concern on solving the problem of oil price increase and depreciation of exchange rate on Indonesia's food price as they are important factors that can affect the price stability. The government should not rely on food imports because the price is strongly influenced by the movements in the exchange rate.

We in the Korea Institute for Advanced Study are preparing the fifth Horizon Run in a series of large-scale cosmological simulations. For the first time we will include full hydrodynamics and astrophysical processes using a RAMSES code. I will discuss the impact of large-scale structures on smaller scale properties in cosmological hydrodynamic simulation to justify our choice of simulation boxsize, whose one side length is up to 1 Gpc.

Objectives: Environmental pollution is a negative consequence of the development process, and many countries are grappling with this phenomenon. As a developing country, Iran is not exempt from this rule, and Iran pays huge expenditures for the consequences of pollution. The aim of this study was to analyze the long- and short-run impact of air pollution, along with other health indicators, on private and public health expenditures. Methods: This study was an applied and developmental study. Autoregressive distributed lag estimating models were used for the period of 1972 to 2014. In order to determine the co-integration between health expenditures and the infant mortality rate, fertility rate, per capita income, and pollution, we used the Wald test in Microfit version 4.1. We then used Eviews version 8 to evaluate the stationarity of the variables and to estimate the long- and short-run relationships. Results: Long-run air pollution had a positive and significant effect on health expenditures, so that a 1.00% increase in the index of carbon dioxide led to an increase of 3.32% and 1.16% in public and private health expenditures, respectively. Air pollution also had a greater impact on health expenditures in the long term than in the short term. Conclusions: The findings of this study indicate that among the factors affecting health expenditures, environmental quality and contaminants played the most important role. Therefore, in order to reduce the financial burden of health expenditures in Iran, it is essential to reduce air pollution by enacting and implementing laws that protect the environment.

본 연구는 최초 기업공개(IPO) 이후 발생하는 공모가격의 저가발행(underpricing) 현상 및 투자자 관심(investor attention)과의 상호 작용 분석을 통해, 정보기술(IT) 기업의 IPO 이후 장·단기 성과를 분석하였다. IPO 시점의 구글 검색량으로 투자자의 관심을 측정하였을 때, 기타 제조업 또는 서비스 기업 대비 IT 기업에 대한 투자자의 관심도 증분이 상대적으로 컸으며 IT 기업에 대한 저가발행 현상도 더 심하게 나타났다. IPO 이후의 단기간 성과 분석 결과, IPO 기업에 대한 투자자 관심의 증가는 IT 및 비IT 기업의 성과에 정(+)의 영향을 줄 뿐 아니라 IPO 시점의 저가발행 정도가 클수록 투자자 관심의 효과가 증가하는 것으로 나타났다. 장기적 관점에서 볼 때, 비IT 기업의 저가발행 및 이에 동반된 투자자 관심의 증가 효과는 점차적으로 약화되는 반면 IT 기업에 대한 효과는 장기간 지속되었다. 비IT 기업과 달리, 네트워크 효과 등 산업 구조적 특성의 영향을 받는 IT 기업의 경우 저가발행 및 이와 더불어 향상된 초기 투자자 관심효과가 장기적으로 기업의 실질적 가치에 영향을 준 것으로 나타났다.
