One of the central problems in migration measurement arises as a consequence of the different sources of migration data. Most information regarding migration is obtained from population censuses or population registers that report migration data for a given time interval. Another source of migration data is the sample survey which may be designed to provide information about both migrants and...

Technology spillover from trade channel is important. Absorbing foreign technology by the channel of importation and using the latent technology in those products create export development, increase the quality and quantity of manufactured goods, and modify management, technology improvements and production of goods with high added value; this might favorise optimal allocation of resources. Imp...

This paper presents a monopolistic competition model of trade and multinational production that incorporates asymmetric trade barriers and international differences in production costs. The model predicts the functional form for the dependence of U.S. exports and multinational production on tariffs, distance, and production costs. To deal with simultaneity, we estimate the nonlinear equations o...

We ask whether the threat of carbon tariffs might lower the cost of reductions in world carbon emissions by inducing unregulated regions to adopt emission controls. We use a calibrated simulation model to generate the payoffs of a game in which a coalition regulates its own emissions and chooses whether or not to employ carbon tariffs against unregulated regions. Unregulated regions respond by ...

In our paper on "Revenue Seeking: A Generalization of the Theory of Tariffs" (1980), we extended the theory of tariffs to include revenue seeking. We also compared tariffs with quotas, under seeking activities associated with the revenues from the former and with the rents (i.e., license premia) from the latter. We argued, among other propositions, that: (1) Revenue seeking was a zero-output ac...

Unilateral carbon policies are inefficient due to the fact that they generally involve emission reductions in countries with high marginal abatement costs and because they are subject to carbon leakage. In this paper, we ask whether the use of carbon tariffs — tariffs on the carbon embodied in imported goods — might lower the cost of achieving a given reduction in world emissions. Specifically,...

Unilateral carbon policies are inefficient due to the fact that they generally mean that abatement takes place in high-cost countries and because they are subject to carbon leakage. In this paper, we ask whether the use of carbon tariffs — tariffs on the carbon embodied in imported goods — might lower the cost of achieving a given reduction in world emissions. Specifically, we explore the role ...
