The recent impetus of tougher immigration-related measures passed at the state level raises concerns about the impact of such measures on the migration experience, trajectory, and future plans of unauthorized immigrants. In a recent and unique survey of Mexican unauthorized immigrants interviewed upon their voluntary return or deportation to Mexico, almost a third reported experiencing difficulties in obtaining social or government services, finding legal assistance, or obtaining health care services. Additionally, half of these unauthorized immigrants reported fearing deportation. When we assess how the enactment of punitive measures against unauthorized immigrants, such as E-Verify mandates, has affected their migration experience, we find no evidence of a statistically significant association between these measures and the difficulties reported by unauthorized immigrants in accessing a variety of services. However, the enactment of these mandates infuses deportation fear, reduces interstate mobility among voluntary returnees during their last migration spell, and helps curb deportees’ intent to return to the United States in the near future.

In this collection, distinguished economists, political scientists, and legal experts discuss the implications of the ever more globalized protection of intellectual property rights for the ability of countries to provide their citizens with such important public goods as basic research, education, public health, and sound environmental policies. Such items increasingly depend on the exercise of private rights over technical inputs and information goods, which could usher in a brave new world of accelerating technological innovation. However, higher and more harmonized levels of international intellectual property rights could also throw up high roadblocks in the path of follow-on innovation, competition, and the attainment of other social objectives. It is at best unclear who represents the public interest in negotiating forums dominated by powerful knowledge cartels. This is the first book to assess the public processes and inputs that an emerging transnational system of innovation will need to promote technical progress, economic growth, and welfare for all participants.

Given the unprecedented increase in the flow of migrants from El Salvador, Guatemala, and Honduras to the United States, this article analyzes the impact of U.S. interior enforcement on parent-child separations among Central American deportees, along with its implications for deportees' intentions to remigrate to the United States. Using the EMIF sur survey data, we find that interior enforcement raises the likelihood of parent-child separations as well as the likelihood that parents forcedly separated from their young children report the intention to return to the United States, presumably without documents. By increasing parent-child separations, interior enforcement could prove counterproductive in deterring repetitive unauthorized crossings among Central American deportees.
