Based on a welfare-maximization model of skilled migration where education generates a positive externality, this paper examines whether the early view regarding brain drain's (BD) negative impact on source countries - and the Bhagwati tax (𝐵𝑇) associated with it - is compatible with the...

Numerous developing economies depend vitally on renewable natural-resource (NR)-based commodities. This study develops a general equilibrium model to examine the steady-state impact of changes in a small economy's NR congestion under open access and optimal regulation. This issue has often been...

Based on a welfare-maximization model of skilled migration where education generates a positive externality, this paper examines whether the early view regarding brain drain's (BD) negative impact on source countries and the Bhagwati tax (BT) associated with it, is compatible with the recent...

Ability drain's (AD) impact on host countries is significant: 30 percent of US Nobel laureates since 1906 are immigrants, and they or their children founded 40 percent of Fortune 500 companies. However, while brain drain (BD) and gain (BG) have been studied extensively, AD has not. I examine...

Many developing countries depend crucially on open-access renewable natural resources (NR). Trade is generally viewed as hurting the long-term health of NR in commodity-exporting countries. I examine whether trade might be beneficial in the case of population growth. Dynamic general equilibrium...

Is ability drain (AD) economically significant? That immigrants or their children founded over 40% of the Fortune 500 US companies suggests it is. Moreover, brain drain (BD) induces a brain gain (BG). This cannot occur with ability. Nonetheless, while BD has been studied extensively, AD drain...

With the 1967 reform, Canada's immigration policy changed from a country-preference system to a points system. The latter provides points according to applicants' education level but abstracts from the quality of their education. This paper considers the points system, the country-preference...
