Other Research
2018: Choi, J.Y., & Yu, E.S., Podcast by ADBI Asia's Developing Future Global outsourcing comes with environmental costs. This podcast, edited by Asian Development Bank Institute in Tokyo (Japan), reports the welfare consequences of international outsourcing between North and South in the presence of resulting environmental damages to the South. We suggest that to fully resolve the environmental issue in the South, strengthening regulation or fostering international cooperation is desirable for implementation until the environmental costs of outsourcing are fully accounted for by the outsourcing firms in the North which, however, may react by resorting to insourcing, diversified outsourcing and other strategies.
Basic or Discovery Scholarship
2015: Choi, J.Y. & Yu, E.S., A Public Good Approach to Environmental Economy.
This paper investigates the economic implications of environment in the 2x3 Heckscher-Ohlin model by expounding the multi-dimensional roles of the environment for the economy: (i) as a public input used for production of goods and services, (ii) as a by-product from production of goods and services, and (iii) as a public good directly affecting social utility. It shows that (a) the sectoral environment-output responses play a critical role for determining the environmental effects on factor prices, sectoral outputs and employment, and welfare; (b) the optimal policy is free trade (a specific tax on pollution) under a dynamically stable (unstable) environment.
