This dissertation consists of two independent studies. The first study belongs to the field of environmental economics and the second is on international trade, with a focus on offshoring.
In the first study, we investigate firm investment in advanced abatement technology under a heterogeneous firms framework. In contrast to existing literature, we find that the optimal level of investment in advanced abatement technology is an inverted U-shaped function of firm productivity. More-productive firms have superior environmental performance, in the sense that they have lower emission per unit of output. Comparative statics shows that in response to a tighter environmental regulation, more-productive firms tend to raise their investment in advanced abatement technology while less-productive firms do the opposite. Key theoretical predictions are confirmed by Chinese data.
The second study analyzes the decision of a multinational firm from a developed country to slice a production chain to allocate different tasks of the production chain globally. The process involves a wide range of tasks that varies from very routine jobs to very research and development (R&D) intensive work. We find that under certain conditions, a drop in offshoring costs (1) leads to more slicing (an increase in the length of production chain) and more offshoring, (2) stimulates R&D, and (3) raises employment in the developed country. / published_or_final_version / Economics and Finance / Doctoral / Doctor of Philosophy
