Urbanization economies - the effects on productivity and utility created endogenously by larger cities - are a fundamental component of both the economic geography of modern societies and the perpetuation of innovation and economic growth at a national level. Cities account for vast majorities...

A prominent feature of economic geography in America is the positive correlation amongst local incomes, housing costs and city population. This paper embeds a "black box" agglomeration economy within a more neoclassical general equilibrium model of local wages, rents and population to assess the...

Travel restrictions are often imposed to limit the spread of infectious diseases. As uniform restrictions can be inefficient and incur unnecessarily high costs, this paper examines the optimal design of restrictions that target specific travel routes. We propose a model with trade-offs between...

This paper develops a new equilibrium model of two-sided search where ex-ante heterogenous individuals have general payoff functions and vectors of attributes. The analysis applies to a large class of models, from the non-transferable utility case to the collective household case with...

We document the recent phenomenon of uphill flows of capital from nonindustrial toindustrial countries and analyze whether this pattern of capital flows has hurt growth innonindustrial economies that export capital. Surprisingly, we find that there is a positivecorrelation between current...

This paper analyzes the impact on age group wage differentials in a setting of imperfect labor substitution at different ages (years) of working life. We examine the wage prospect of assuming medium, high, and low levels of fertility during the population projection period (2020-2090). Main...

Using a new survey of firms' inflation expectations in France, we provide novel evidence about the measurement and formation of inflation expectations on the part of firms. First, French firms report inflation expectations with a smaller, but still positive, bias than households and display less...

We consider the aggregate and distributional impact of Universal Basic Income (UBI). We develop a model to study a wide range of UBI programs and financing schemes and to highlight the key mechanisms behind their impact. The most crucial channel is the rise in distortionary taxation (required to...

This paper reviews models of marriage, with special emphasis on how the sex ratio (the ratio of marriageable men to women) can help explain measurable outcomes such as marriage formation, intra-marriage distribution of consumption goods, savings, labor supply, leisure, type of relationship,...

Households' and firms' subjective inflation expectations play a central role in macroeconomic and intertemporal microeconomic models. We discuss how subjective inflation expectations are measured, the patterns they display, their determinants, and how they shape households' and firms' economic...
