Illegal immigration: a supply side analysis

"This paper analyzes the supply-side determinants of illegal immigration using a three-sector general equilibrium model of the source country. Agricultural liberalization raises illegal immigration while liberalization of the high tech sector reduces it. In contrast, capital mobility in the source country renders trade policy ineffective for controlling illegal immigration. Paradoxically, increased enforcement (by the host country) may raise source country unskilled wages, although illegal immigration falls. Finally, under capital mobility, a rise in the source country restrictions on capital inflow raises the level of illegal immigration and reduces the effectiveness of border enforcement efforts by the host country."     

U.S. IMMIGRATION REFORM: POLICY ISSUES AND ECONOMIC ANALYSIS

In recent years, legal U. S. immigration has approached historically high levels, and illegal immigration has been thought to be high and perhaps rising. Consequently, the Select Commission on Immigration and Refugee Policy proposed sweeping changes in the nation's immigration laws. During 1984, both the Senate and House passed the Immigration Reform and Control Act (Simpson-Mazzoli Bill). This bill subsequently died in the conference committee that was established to reconcile differences between the bill's two versions. The proposed act has three major provisions: (1) control of illegal immigration, (2) legalization of alienstatus, and (3) reform of legal immigration. Both the House and Senate versions would maintain the present orientation of U.S. immigration policy toward family reunification, but the Senate proposed significant changes in legal immigration restrictions that would shift policy slightly more toward labor considerations. These proposed changes were eliminated in the compromise made in the conference committee. Employer sanctions and legalization of illegal aliens were left as the two most prominent alterations to existing policy. During 1985, the 99th Congress is likely to reconsider the Simpson-Mazzoli Bill, perhaps in a streamlined version which emphasizes employer sanctions, legalization, and a substantial increase in border enforcement.     

Controlling Illegal Immigration: Border Control vs. Domestic Enforcement

This paper presents a two-country general equilibrium model where international mobility of labor is prohibited. Illegal immigration nevertheless occurs. The probability of success at illegal immigration depends on resources allocated to border control and domestic enforcements. We examine the effects of switching resources form border control to domestic enforcement on illegal immigration and on welfare levels. We characterize the allocation of resources between the two methods of immigration control, that minimizes illegal immigration, and find that, starting from this allocation, moving resources from border control to domestic enforcement is unambiguously welfare improving for the destination country.

     

Intentions to Return of Clandestine Migrants: Comment

We take issue with the reasoning of Coniglio et al. ( 2009 ) that whereas better‐skilled illegal migrants will prefer to return‐migrate, lower‐skilled illegal migrants will not. We argue that under asymmetric information, all the illegal migrants are initially paid a wage based on the average productivity of the group of illegal migrants. The better‐skilled illegal migrants thus face two “taxes:” being paid less than if they were legal, and being averaged down. Therefore, better‐skilled illegal migrants can be expected to expend more effort to become legal than lower‐skilled illegal migrants. And once legalized, there is no reason for the better‐skilled illegal migrants to want to return to their country of origin more than the lower‐skilled illegal migrants. Thus, it is the lower‐skilled illegal migrants that are likely to dominate the return migration flow. We argue that in other respects too, the model of Coniglio et al. is not based on reasonable assumptions, and that even under the postulated assumptions, the model suffers from several inconsistencies. In particular, when the rate of return to savings is an increasing function of skill level, we would expect there to be few better‐skilled individuals among illegal migrants in the first place. Also, an obvious distinction between savers and borrowers is ignored.     

Illegal aliens,unemployment and immigration policy

"This paper develops a simple two-country model of illegal immigration in an attempt to examine the interaction among variables such as the stock of migrant labor, the unemployment rates of the two economies, and the rate of spending by the host country on the enforcement of its immigration restrictions. The focus of the analysis is on the dynamics of immigration policy and on its role in determining the nature of the mechanism by which disturbances to the labor market of one country are transmitted to that of the other in the short run and in the long run."     

Government policy under price uncertainty: A source of volatility in illegal immigration

This paper provides an alternative explanation for why illegal immigration can exhibit substantial volatility. We develop a model economy where migrants make decisions in the face of uncertain border enforcement and transfers from the host country. The uncertainty is extrinsic, a sunspot, and arises due to ambiguity regarding government policy; the sunspot manifests itself as uncertainty in the commodity price of money. Immigration volatility stems from both the trade‐off between the marginal benefits and costs (transfers and enforcement) to migrating and the existence of a sunspot. Finally, we examine the impact of changes in government policies on migration levels.     

Illegal immigration in a heterogeneous labor market

This paper examines the effects of illegal immigration in a neoclassical growth model with two groups of workers, skilled and unskilled. We show that although illegal immigration is a boon to a country as a whole, there are distributional effects, whose sign is in general ambiguous. This is because all sources of income of both groups are affected and some of these changes tend to move income in opposite directions. Nevertheless, calibration exercises show that the wealth distribution is likely to become more unequal as the number of illegal immigrants increases. We confirm most of our calibration results analytically in a small open economy version of the basic model. Finally, our results remain robust when we extend the model to allow for endogenous skill acquisition.     

The U.S. immigration crisis

A review of the factors affecting immigration to the United States is presented. The authors develop the argument that present levels of immigration, particularly illegal immigration, are detrimental to U.S. interests, and that current global population trends will make this situation progressively worse. Stricter controls on immigration are considered.     

A theory of permissible illegal immigration

In many countries laws are not enforced against visibly present illegal immigrants. The visibly present illegal immigrants also tend to be concentrated in particular sectors. We explain such permissible illegal immigration in an endogenous-policy model where selective sector-specific illegality transforms illegal immigrants from non-sectorally specialized to sector-specific factors of production. Under initial conditions where no immigrants are present, the median voter opposes immigration. When, however, a population of illegal immigrants has accumulated, ongoing illegal immigration becomes an endogenous equilibrium policy, at the same time that a majority of voters opposes legal immigration and opposes amnesty that would legalize the immigrants' presence. We also establish a basis for domestic voters preferring that illegal immigrants be employed in service rather than traded-goods sectors.     

Efficiency Wages and International Factor Mobility

This paper incorporates efficiency wages into the Heckscher-Ohlin model. The capital intensive sector pays higher wages than the other sector. One result is that tariffs to attract capital increase welfare by increasing the quality, not quantity, of jobs available. However, there are distributional effects among laborers. Some see an increase in wages, others become unemployed. The paper also investigates policies in the presence of illegal immigration. If immigration cannot be limited, a high wage country is best served by a capital outflow that eliminates the incentive for the labor inflow. Again, there are distributional effects among the workers. [F20]     

Immigration vs. outsourcing: Effects on labor markets

Anti-globalizers are concerned, inter alia, with the effects on a developed country's real wage rate of legal or illegal immigration, as well as the outsourcing of labor-intensive activities abroad. Although a lowering of the wage rate may ensue, it is by no means a logical necessity. I show that either immigration or outsourcing of a labor-intensive fragment of production may serve to raise the wage rate of national labor in a developed country. As well, I point out how these two effects differ from each other.     

Illegal immigration in the presence of labor unions

"This paper develops a general equilibrium framework of a two-sector economy which incorporates illegal immigration in the presence of labor unions. It demonstrates that stricter enforcement of immigration laws, by reducing the demand for or supply of illegal aliens, benefits all legal workers in the economy. The model is used to evaluate the impact of these policy changes on national income. Results indicate that national income does not necessarily fall when immigration controls are tightened. The existence of a union mitigates the negative welfare impact of a reduction in the number of illegal immigrants."     

Risk preference,immigration policy and illegal immigration

The paper analyzes the effects of government policy upon illegal immigration. The model used as a vehicle for this analysis is an extension of Ethier's one-small-country model of illegal immigration to a two-country context. We distinguish between the cases of capital immobility and free capital mobility, and consider illegal immigration when there are border patrols by the government and when there are internal enforcement procedures in effect. Unlike previous researchers who have assumed risk neutrality, we examine the impacts of government policy when prospective illegal immigrants exhibit risk averse and risk loving behavior. The relaxation of the risk neutrality assumption leads to the possibility of multiple and unstable equilibria. Moreover, attitudes to risk and the probability of detection are shown to have implications for some equilibrium responses to tighter surveillance.

Illegal Immigration and Second-best Import Tariffs

A version of the small‐union Meade model is presented to analyze the illegal immigration problem in the context of import tariffs. Two possible host nation objectives are considered: (i) to control the level of illegal immigration to a given target; or (ii) to choose an illegal immigration level that maximizes national welfare. Available policy instruments are import tariffs/subsidies, border, and internal enforcement levels. The second‐best tariff on imports from the source nation (for illegal immigration) can be of either sign. It depends on the effect of the tariff on the wage rate and the pattern of substitutability in consumption. In scenario (ii), greater enforcement may be justified if it reduces labor inflow and thereby contracts the protected sector. If enforcement is too costly, tariff policy may substitute for it to exploit monopsony power in the labor market and to counter the distortionary effects of labor flows.     

Auctioning Immigration Visas

Freeman (2006 ) suggested that auctioning immigration visas and redistributing the revenue to native residents in the host country would increase migration from low-income to high-income countries. The effect of the auctioning of immigration visas, in the Ricardian model from Findlay (1982 ), on the optimal level of immigration for the host country is considered. It is shown that auctioning immigration visas will lead to a positive level of immigration only if the initial wage difference between the host country and the source country is substantial. The cost of the immigration visa is more than half the earnings of the immigrant worker.     

Work Effort, Moderation in Expulsion, and Illegal Migration

Illegal migrants supply a valuable productive input: effort. But their status as illegals means that these migrants face a strictly positive probability of expulsion. A return to their country of origin entails reduced earnings when the wage at origin is lower than the wage at destination. This prospect induces illegal migrants to exert more work effort than comparable workers who face no such prospect. The lower the probable, alternative earnings, the harsher the penalty that illegal migrants will be subjected to upon their return, for a given probability of expulsion, and the higher the level of effort they will exert at destination. While the home‐country wage that awaits the illegal migrants upon their return is exogenous to the host country, the probability of their return is not. Given the home‐country wage, a higher probability of expulsion will induce illegal migrants to supply more effort. Hence, different combinations of probabilities of expulsion and home‐country wages yield the same level of effort. Thus, variation in the extent to which receiving countries undertake measures aimed at apprehending and expelling illegal migrants can be attributed not to characteristics of the illegal migrants themselves but to a feature that pertains to the illegal migrants’ country of origin.     

International immigration and economic welfare in an efficiency wage model: The co-existence case of both legal and illegal foreign workers

Abstract. In the developed countries some native workers are unemployed while there exist illegal unskilled (legal skilled) foreign workers who are complementary to (substitutable for) natives and their wages are usually lower than (equal to) that of natives. Reflecting this situation, we introduce two types of immigrant in an efficiency wage model. It is shown that domestic government should exclude illegal foreign workers but welcome legal ones if the total number of illegal immigrants is small enough and well controlled. On the other hand, legal immigration should be restricted if the flood of illegal immigration is out of control.     

Leniency policies and illegal transactions

We study the consequences of leniency—reduced legal sanctions for wrongdoers who spontaneously self-report to law enforcers—on sequential, bilateral, illegal transactions, such as corruption, manager–auditor collusion, or drug deals. It is known that leniency helps deterring illegal relationships sustained by repeated interaction. Here we find that—when not properly designed—leniency may simultaneously provide an effective governance mechanism for occasional sequential illegal transactions that would not be feasible in its absence.     

(In)Effective tax enforcement and demand for cash

Cash holdings have increased worldwide in recent years. It is well known that a higher tax burden is typically an important factor in explaining an increase in cash holdings. However, the role of tax enforcement is less known. To explore the effect of tax enforcement on cash holdings, we study fiscal reform carried out in a large, developing country. In mid-2013, Mexico tried to raise tax revenues by enrolling more taxpayers and introducing electronic invoices to counter a secondary market in illegal invoices. Based on a transaction-based model of money demand, we find an ambiguous effect of tougher tax enforcement on money holdings. If institutions are ineffective, the model predicts an increase in cash holdings after tougher enforcement. To test this issue empirically, we propose a vector error correction (VEC) specification for money demand. The results suggest that a tax enforcement policy implemented under a weak institutional framework can exacerbate cash holdings.
