This paper demonstrates that a pollution tax with a fixed cost component may lead, by itself, to segregation between clean and dirty firms without heterogeneous preferences or increasing returns. We construct a simple model with two locations and two industries (clean and dirty) where pollution...

What are the effects of the WTO’s TRIPS Agreement on growth, welfare and income inequality? To analyze this question, we develop an open-economy R&D-growth model with wealth heterogeneity. Under TRIPS, the North experiences higher growth and welfare at the expense of higher income inequality....

What are the effects of strengthening developing countries' protection for intellectual property rights on economic growth, social welfare and income inequality in the global economy? To analyze this question, we develop a two-country R&D-based growth model with wealth heterogeneity. We find...

What are the effects of the WTO's TRIPS Agreement on growth, welfare and income inequality? To analyze this question, we develop an open-economy R&D-driven endogenous-growth model with wealth heterogeneity. Under TRIPS, the North experiences higher growth and welfare at the expense of higher...

This paper construct a two-sector model of two-period lived overlapping generations with endogenous occupational choice where ability-heterogeneous agents choose whether to become educated when young and henceforth to become skilled when old. We show that endogenous occupational choice in this...

The long-term trends of urbanization suggest: not only have more cities formed, but the leading metropolises have grown larger, with a number of peripheral subcenters developing over time. Conventional models of urban growth are limited, in that commuting cost and congestion eventually result in...

This paper studies the patterns and key determinants of staged economic development. We construct a two-sector dynamic general equilibrium model populated with one-period lived non-overlapping generations, featuring endogenous enhancement in modern technology and endogenous accumulation of labor...

We construct a staged development framework with multi-period discrete choices to study the colonization of Hong Kong, which facilitated the trade of several agricultural and manufactured products, including opium, between Britain and China. The model is particularly designed based on historical...
