    Abstract: The level of ethnic diversity is believed to have significant consequences for economic and political development within countries. In this article, we provide a theoretical and empirical analysis of the determinants of ethnic diversity in the world. We introduce a model of cultural and ge- netic drift where new ethnic groups endogenously emerge among periph- eral populations as a response to an insufficient supply of public goods. In line with our model, we find that the duration of human settlements has a strong positive association with ethnic diversity. Ethnic diversity decreases with the length of modern state experience and with distance from the equator. Both "primordial" and "constructivist" hypotheses of ethnic fractionalization thus receive some support by our analysis.<p>

    Abstract: In this paper, we examine net emigration from Mexico over the period 1960 to 2000. The data are consistent with labor-supply shocks having made a substantial contribution to Mexican emigration, accounting for one third of Mexican labor flows to the U.S. over the last 25 years of the 20th century. Net emigration rates by Mexican state birth-year cohort display a strong positive correlation with the initial size of the Mexican cohort, relative to the corresponding U.S. cohort. Labor-demand shocks also contribute to emigration, but the state-specific component of these is muted relative to labor supply. In states with long histories of emigration, the effects of cohort size on emigration are relatively strong, consistent with the existence pre-existing networks. In states without a history of emigration, the effects of cohort size on emigration accelerate as a cohort ages, consistent with the creation of new networks.

    Abstract: This short paper proposes a non-parametric method of accounting for the distribution of background characteristics when testing for segregation in empirical studies. It is shown and exemplified—using data on workplace segregation between immigrants and natives in Sweden—how the method can be applied to correct any measure of segregation for differences between groups in the distribution of covariates by means of simulation, and how analytical results can be used when studying segregation by means of peer group exposure.

    Abstract: The Phillips curve has flattened in Spain over 1995-2006: unemployment has fallen by 15 percentage points, with roughly constant inflation. This change has been more pronounced than elsewhere. We argue that this stems from the immigration boom in Spain over this period. We show that the New Keynesian Phillips curve is shifted by immigration if natives’ and immigrants’ labour supply or bargaining power differ. Estimation of the curve for Spain indicates that the fall in unemployment since 1995 would have led to an annual increase in inflation of 2.5 percentage points if it had not been largely offset by immigration.

    Abstract: Migrant remittances are an increasingly important type of international financial flow for providing both additional resources for development as well as consumption expenditures for poverty alleviation. One geographical area where these flows are quite significant is in the CIS economies both in terms of their sheer size as well as their economic importance in providing a source of external finance for the recipient countries. Data on remittances generally, but especially in this region, are often of poor reliability due to the fact that these flows often move through unofficial and unmonitored channels. Data for the CIS are limited in that several countries do not provide this information in their balance of payment statistics and in those that do, it is often only partially reported and poorly collected or estimated. In this paper the characteristics, trends, and importance of remittances in the CIS are discussed and a new approach for estimating remittance flows in the CIS is developed based upon a new set of financial data recently released by the Central Bank of Russia and unpublished data obtained from the central banks of Kazakhstan, Moldova and Ukraine.
