In this paper we document a strong positive correlation of immigration flows with changes in average wages and average house rents for native residents across U.S. states. Instrumental variables estimates reveal that the correlations are compatible with a causal interpretation from immigration to wages and rents of natives. Separating the effects of immigrants on natives of different schooling levels we find positive effects on the wages and rents of highly educated and small effects on the wages (negative) and rents (positive) of less educated. We propose a model where natives and immigrants of three different education levels interact in production in a central district and live in the surrounding region. In equilibrium the inflow of immigrants has a positive productive effect on natives due to complementarieties in production as well as a positive competition effect on rents. The model calibrated and simulated with U.S.-states data matches most of the estimated effects of immigrants on wages and rents of natives in the period 1990-2005. This validation suggests the proposed model as a useful tool to evaluate the impacts of alternative immigration scenarios on U.S. wages and rents.

In the wake of falling trade costs, two central consequences in the importing economy are, first, that stronger competition through increased imports can lead to market share reallocations among domestic firms with different productivity levels (selection). Second, the increase in imports might improve domestic technologies through learning externalities (spillovers). Each of these channels may have a major impact on aggregate productivity. This paper presents comparative evidence from a sample of OECD countries. We find that the average long run effect of an increase in imports on domestic productivity is close to zero. If the scope for technological learning is limited, the selection effect dominates and imports lead to lower productivity. If, however, imports are relatively technology-intensive, imports also generate learning that can on net raise domestic productivity. Moreover, there is somewhat less selection when the typical domestic firm is large. The results support models in which trade triggers both substantial selection and technological learning.

Does productivity increase with density? We revisit the issue usingFrench wage and TFP data. To deal with the ‘endogenous quantity of labour' bias (i.e., urban agglomeration is consequence of high local productivity rather than a cause), we take an instrumental variable approach and introduce a new set of geological instruments in addition to standard historical instruments. To dealwith the ‘endogenous quality of labour' bias (i.e., cities attract skilled workers so that the effects of skills and urban agglomeration are confounded), we take a worker fixed-effect approach with wage data. We find modest evidence about theendogenous quantity of labour bias and both sets of instruments give a similar answer. We find that the endogenous quality of labour bias is quantitatively more important.

We estimate the effects of major roads and public transit on the growth of major cities in the US between 1980 and 2000. We find that a 10% increase in a city’s stock of roads causes about a 2% increase in its population and employment and a small decrease in its share of poor households over this 20 year period. We also find that a 10% increase in a city’s stock of large buses causes about a 0.8% population increase and a small increase in the share of poor households over this period. To estimate these effects we rely on an instrumental variables estimation which uses a 1947 plan of the interstate highway system and an 1898 map of railroads as instruments for 1980 roads.

With preferential trade agreements on the rise worldwide rules of origin which are necessary to prevent trade deflection are attracting increasing attention. At the same time, preference erosion for Generalized System of Preferences (GSP) recipients is increasing resistance to further multilateral negotiations. Drawing on different approaches, this article shows that the current system of rules of origin that is used by the European Union and the United States in preferential trade agreements (including the GSP) and that is similar to systems used by other Organization for Economic Co-operation and Development (OECD) countries should be drastically simplified if developed economies really want to help developing economies integrate into the world trading system. In addition to diverting resources for administrative tasks, current rules of origin carry significant compliance costs. More fundamentally, it is becoming increasingly clear that they are often been designed to force developing economies to buy inefficient intermediate products from developed economies to pay for preferential access for the final product. The evidence also suggests that a significant share of the rents associated with market access (net of rules of origin compliance costs) is captured by developed economies. Finally, the restrictiveness of rules of origin is found to be beyond the levels that would be justified to prevent trade deflection, suggesting a capture by special interest groups. The article outlines some alternative paths to reforms.

This paper reviews alternative approaches to measuring an economy's cost competitiveness and proposes some new measures inspired by the economic theory of index numbers. The indices provide a theoretical benchmark for estimated real effective exchange rates, but differ from standard measures in that they are based on marginal rather than average sectoral shares in GDP or employment. The use of the new indices is illustrated by some simple calculations which highlight the potential exposure of the Irish economy to fluctuations in the euro-sterling exchange rate.
