Host countries have implemented permanent and guest-worker (GW) immigration programs in recent decades, while the temporary movement of service providers under Mode IV of the GATS is one of the issues being negotiated at the Doha Round of the WTO. Though decisions on what programs to adopt have...

This paper examines the relationship between the brain drain and country size, as well as the extent of small states' overall loss of human capital. We find that small states are the main losers because they i) lose a larger proportion of their skilled labor force and ii) exhibit stronger...

Immigration continues to be on the forefront of the policy debate on both sides of the Atlantic. A number of reforms of permanent and guest-worker (GW) immigration programs are being considered, and the temporary movement of service providers under Mode IV (GATS) is being negotiated at the Doha...

This paper establishes a simple theoretical framework which comprises key forces that shape the structure and interrelation of cities to study the interdependencies between urban evolution and the environment. We focus on the potential of the unfettered market forces to economize on emissions. A...

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...

A number of developed countries have implemented guest-worker programs in recent decades. Its basic feature is the temporary presence of the foreign guest-workers. The problem with such programs is that there is little to prevent these guest-workers from entering the illegal job market and...

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...

The core-periphery model by Krugman (1991) has two 'dramatic' implications: catastrophic agglomeration and locational hysteresis. We study this seminal model with CES instead of Cobb-Douglas upper tier preferences. This small generalization suffices to change these stark implications. For a wide...

Models of the new economic geography share a number of common conclusions, but also exhibit notable differences, in particular with respect to the shape of the location pattern and the efficiency of the market equilibrium. This reflects the fact that these models rely heavily on specific...
