We use a version of the small-union Meade model to consider the effects of interdependent import tariffs in the presence illegal immigration. First, we analyze the condition under which illegal immigration is likely to increase (or decrease) in response to reciprocal trade liberalization between...

We use a version of the Meade model to consider the effects of interdependent import tariffs in the presence illegal immigration. First, we consider the small union case and derive the Nash tariff equilibrium for two potential members of a Preferential Trade Agreement (PTA). We analyze...

This paper estimates the causal effect of the prospect of legal status on the employment outcomes of undocumented immigrants. Our identification strategy exploits a natural experiment provided by the 2002 amnesty program in Italy that introduced an exogenous discontinuity in eligibility based on...

Barriers to immigration of low-skilled workers from developing countries into the advanced countries prevent many potential migrants from leaving their countries of origin. With very low home-country wages in relation to the cost of undocumented migration, the opportunity to migrate often hinges...

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 debate on the immigration policies in OECD countries has turned its attention towards illegal migrants. Given that migration flows are determined by immigration laws, the probability of potential detection, penalties for unauthorised migrants and their employers, and on income differences...

This paper looks at the situation of legal immigrants who employ illegal immigrants to provide them with various services. This enables the legal immigrants to allocate more time to other work, thereby increasing their earnings. Illegal immigrants employed by legal immigrants may specialize in...
