This paper studies why illegal immigration is widespread. We develop a political agency model in which a politician decides on an immigration target and its enforcement, facing uncertainty on the supply of migrants. Illegal immigration can arise for two reasons: the policy maker may be unable to...

We build a general equilibrium model in which both illegal immigration and the size of the informal sector are endogenously determined. In this framework, we show that indirect policy measures such as tax reduction and detection of informal activities can be used as substitutes for border...

This paper develops a model of optimizing behavior of asylum seekers whose objective is to reach an advanced country. Their personal characteristics and the challenges anticipated along the way determine whether they try to reach the ultimate destination with the aid of human smugglers or by...

The movement of people differs from the movement of goods and services because people create attachments with those with whom they share social capital, including norms, language, customs, values and culture. South-North migration affects social capital in both places. Four types of...

This paper examines the role of immigrant networks on trade, particularly through the demand effect. First, we examine the effect of immigration on trade when the immigrants consume more of the goods that are abundant in their home country than the natives in a standard Heckscher-Ohlin model and...

We investigate the consequences of redistribution policy on migration and trade in a Standard two-good Heckscher-Ohlin framework. With free trade and factor price equalization, abolishing migration barriers is redundant. With the introduction of government activity, matters change drastically....

Goods trade and international mobility of labor are typically analyzed separately. While there is excellent research in both fields, far less is known about the interrelationships between international migration and international trade. This paper provides a first structurally estimable model of...

This article focuses on an apparent conflict between the standard trade theory and available empirical evidence on factor flows. Theoretically, labor and capital flows must be substitutes. However, empirical papers find migration and FDI to be either substitutes or complements, depending upon...

This paper analyzes the effect of immigration on the terms of trade between the home country and the host country of the immigrants, when immigrants and natives have different demand patterns in a two country and two good Heckscher-Ohlin model

This study adopts a GNP function approach in order to examine the impact of migrant labour on domestic factors of production in the United Kingdom. We also examine the relationship between imports and migrants, which are two different facets of globalisation. We find that an increase in the...
