Public Education for the Children Left Behind

This paper examines the role of public education in the context of parental migration, and it studies the effects of an expansive income tax policy that is adopted to increase public education expenditure per pupil. It is shown that such a policy may exacerbate income inequality in the long run if for the less skilled dynasties, the benefits of more public spending on education does not make up for the negative effects of increased parental absences. However, if the migration-induced tax base erosion is not severe, an expansive income tax policy indeed enhances future human capital for all dynasties, and moreover, it may help the less skilled households escape from the poverty trap, thus reducing long-run inequality.Human Capital; Income Inequality; Parental Migration; Public Education Expenditure; Tax Base Erosion

Low-skilled Immigration and Education Policy with Endogenous Fertility

This paper studies the impact of low-skilled immigration on the host country’s education policy, which is formulated by the natives via voting and refers to both school funding sources and resources in the public funded schools. When the size of low-skilled immigrants is large, it is found that wealthier natives are likely to opt out from public into private school. Four main effects of immigration are taken into account : (1) greater congestion in public school; (2) lower average tax base for education funding; (3) reduced low-skilled wage and so more low-skilled natives’ dependence on public education; (4) higher skill premium, which induces high-skilled natives to privately invest in their children’ s education and hence weakens their support to finance public school. The theoretical predictions are not at odds with cross-country stylized facts revealed in both micro and macro data. Moreover, with endogenous fertility, the opting-out decision taken by some native parents results in the empirically observed fertility differential between natives and immigrantsvoting, taxes and subsidies, education; fertitlity, migration

Low-Skilled Immigration and the Expansion of Private Schools

This paper provides a political-economic model to study the impact of low-skilled immigration on the host country's education system, which is characterized by sources of school funding, the average expenditure per pupil, and the type of parents who are more likely to send their children to publicly or privately funded schools. Four main effects of immigration are considered: (1) greater congestion in public schools; (2) a lower average tax base for education funding; (3) reduced wages for low-skilled workers and so more dependence by low-skilled locals on public education; (4) a greater skill premium, which makes it easier for high-skilled locals to afford private education for their children, and hence weakens their support for financing public school. It is found that when the size of low-skilled immigrants is large, the education regime tends to become more segregated with wealthier locals more likely to opt out of the public system into private schools. The fertility differential between high and low-skilled locals increases due to a quantity/quality trade-off. The theoretical predictions are consistent with empirical evidence from both the U.S. census data and the OECD Programme for International Student Assessment (2003).voting, taxes and subsidies, education, fertility, migration

Low skilled immigration and the expansion of private schools

A political-economic model is provided to study the impact of low-skilled immigration on the receiving country's education system, in terms of sources of school funding, expenditure per pupil, and type of parents who are more likely to send children to privately funded schools. The education regime results from the interplay between households' choices on fertility and education and the public education provided. No exogenous culturally-based difference is assumed among agents. Low-skilled migrant workers differ from their local counterparts only in voting rights and adjustment costs. The impact of immigration on public school congestion, tax base, wages and skill premium are considered. When the number of low-skilled immigrants is large, the education regime tends to become more segregated, with wealthier locals more likely to opt out of the public system into private schools. The fertility differential between high- and low-skilled locals increases due to a quantity/quality trade-off. The theoretical predictions conform to stylized facts revealed in US census data and OECD PISA (2003).double taxation, education funding, fertility, migration, segregation, voting

Low-Skilled Immigration and th Expansion of Private Schools

This paper studies the impact of low-skilled immigration on the host country’s education system, which is characterized by sources of school funding, expenditres per pupil, and types of parents who are more likely to send children to publicly (privately) funded schools. When the size of low-skilled immigrants is large, it is found that wealthier natives are likely to opt out from public into private schools. Four main effects of immigration are taken into account : (1) greater congestion in public school; (2) lower average tax base for education funding; (3) reduced low-skilled wage and so more low-skilled natives to privately invest in their children’s education and hence weakens their support to finance public school.

Non-vanishing Heterotic Superpotentials on Elliptic Fibrations

We present models of heterotic compactification on Calabi-Yau threefolds and compute the non-perturbative superpotential for vector bundle moduli. The key feature of these models is that the threefolds, which are elliptically fibered over del Pezzo surfaces, have homology classes with a unique holomorphic, isolated genus-zero curve. Using the spectral cover construction, we present vector bundles for which we can explicitly calculate the Pfaffians associated with string instantons on these curves. These are shown to be non-zero, thus leading to a non-vanishing superpotential in the 4D effective action. We discuss, in detail, why such compactifications avoid the Beasley-Witten residue theorem.Comment: 1 + 23 page

Remittances and inequality: A dynamic migration model

We develop a model to study the effects of migration and remittances on inequality in the origin communities. While wealth inequality is shown to be monotonically reduced along the time-span, the short- and the long-run impacts on income inequality may be of opposite signs, suggesting that the dynamic relationship between migration/remittances and inequality may well be characterized by an inverse U-shaped pattern. This is consistent with the findings of the empirical literature, yet offers a different interpretation from the usually assumed migration network effects. With no need to endogenize migration costs through the role of migration networks, we generate the same result via intergenerational wealth accumulation.Migration, remittances, inequality
