This paper constructs a general equilibrium model of North-South tradein which the North continually introduces new goods. The rate at whichtechnology diffuses to the South is a function of differences in the cost of production in the two regions. The key result of the model is that labor force...

This paper uses a new database on foreign aid to examine the relationships among foreign aid, economic policies, and growth per capita GDP. We find that aid has a positive impact on growth in developing countries with good fiscal, monetary, and trade policies but has little effect in the...

We collect a new dataset on capital punishment in the US and we propose a test of racial bias based upon patterns of sentence reversals. We model the courts as minimizing type I and II errors. If trial courts were unbiased, conditional on defendants race the error rate should be independent of...

This paper investigates the normative criteria that guide the allocation of a policy task to an elected politician versus an independent bureaucrat. The bureaucrat is preferable for technical tasks for which ability is more important than effort, or if there is great uncertainty about whether...

We provide a new compilation of data on ethnic, linguistic, and religious composition at the subnational level for a large number of countries. Using these data, we measure segregation of groups within the country. To overcome the endogeneity problem that arises because of mobility and...

This paper responds to the comment of Di Tella and Dubra (2013). We first clarify that the model of Alesina and Angeletos (2005) admits two distinct types of multiplicity: one that is at the core of their contribution, and a separate one that is at work in Di Tella and Dubra's example. We then...

Preferences for redistribution, as well as the generosity of welfare states, differ significantly across countries. This paper tests whether there exists a feedback process of the economic regime on individual preferences. We exploit the experiment of German separation and reunification to...

In a world of trade restrictions, large countries enjoy economic benefits, because political boundaries determine the size of the market. Under free trade and global markets even relatively small cultural, linguistic or ethnic groups can benefit from forming small, homogeneous political...
