This paper evaluates two well-known models of growth with inequality that have explicit micro underpinnings related to household choice. With incomplete markets or transactions costs, wealth can constrain investment in business and the choice of occupation and also constrain the timing of entry into the formal financial sector. Using the Thai Socio-Economic Survey (SES), we estimate the distribution of wealth and the key parameters that best fit cross-sectional data on household choices and weal

We identify a key role of factor supply, driven by demographic changes, in shaping several empirical regularities that are a focus of active research in macro and labor economics. In particular, demographic changes alone can account for the large movements of the return to experience over the last four decades, for the differential dynamics of the age premium across education groups emphasized by Katz and Murphy (1992), for the differential dynamics of the college premium across age groups empha

This paper shows that growth and income distribution dynamics are closely linked through occupation, financial intermediation, and education. We use micro data from Thailand for 1976–1996. The compositional changes across these characteristics account for half of the Thai inequality increase and 40% of the Thai growth and poverty reduction. Financial deepening and educational expansion contributed to increasing inequality, whereas occupational transformation contributed to poverty alleviation. T

The Kuznets curve postulates a dynamic relationship between growth and income inequality for a given economy. These two aggregate phenomena are linked through compositional changes in individual characteristics when self-selection is constrained by personal wealth. This paper attempts to identify the crucial characteristics associated with this dynamic relationship, by studying the evolution of the income distribution in Thailand between 1976 and 1996, during which the economy experienced strong

This study analyzes the relationship among financial development, economic growth, and income inequality using cross-country panel VAR models. Most...

This paper analyzes the Republic of Korea's rapid and sustained growth experience for the past six decades from the perspective of the neoclassical growth model (the workhorse model of the World Bank’s Long Term Growth Model (LTGM) project). Overall, the sources of Korea's growth were balanced among labor market and demographic factors, capital investment, human capital accumulation, and productivity growth. However, the main engine of growth evolved sequentially, e.g., labor and human capital f

본 실험에서 메탄올을 추출 용매로 한 인삼, 쑥, 그리고 솔잎 추출물을 수동분무기를 이용하여 호흡을 통해 직접 실험 동물에게 투여하였을 경우 그 효과가 폐의 구조를 유지하는데 도움을 줄뿐만 아니라 항산화 효소에도 길항적인 효과를 나타냄을 알 수 있었다. 즉, 추출물을 흡입시킴으로서 세포막의 지질과산화를 억제하여 세포의 구조와 기능을 유지함으로써 흡연으로 인한 세포의 파괴 및 불규칙적인 구조 이상을 줄일 뿐만 아니라 추출물에 포함되어 있는 인삼의 saponin, 쑥의 sesquiterpene과 cineol, 솔잎의 rutin 등의 항산화제의 작용에 의해 흡연으로 생긴 유해 라디칼의 분해를 촉진시키거나 항산화 효소의 활성을 증가시킴으로써 폐의 정상적인 기능에 도움을 주는 것으로 생각된다. 특히, 지금까지 연구되어진 in vitro나 in vivo에서의 경구투여나 주사를 통한 방법이 아니라 호흡을 통해 직접 폐에 투입함으로써 그 결과가 빠르게 나타날 수 있을 것으로 생각된다.

Most of air pollution in a metropolis is the result of exhaust gas emissions from automotive vehicles, and the world-wide regulation against environmental pollution is becoming stricter. Hereupon the demand on development and supply of an environment-friendly automobile is increasing and the market of it is expected to grow rapidly in this time of high oil price. Therefore this research aims at developing the techniques of safety and performance evaluation for Hybrid Electric vehicles. Possible

This paper explains and measures the sources of TFP by developing a method of growth accounting based on an integrated use of transitional growth models and micro data. We decompose total factor productivity (TFP) growth into the occupational-shift effect, financial-deepening effect, capital-heterogeneity effect, and sectoral-Solow-residuals. Applying this method to Thailand, which experienced rapid growth with enormous structural changes between 1976 and 1996, we find that 73 percent of TFP gro
