Seaports facilitate the fast flow of goods across space, but ports also entail local costs borne by host cities. We use the introduction of containerized shipping to explore the effects of port development. At the local ...Read more...

Endogenous mobility in pandemics: theory and evidence from the United States

We study infectious diseases in a spatial epidemiology model with forward-looking individuals who weigh disease environments against economic opportunities when moving across regions. This endogenous mobility allows regi...Read more...

Endogenous cross-region human mobility and pandemics

We study infectious diseases using a Susceptible-Infected-Recovered-Deceased model with endogenous cross-region human mobility. Individuals weigh the risk of infection against economic opportunities when moving across re...Read more...

Technology, market structure and the gains from trade

We study the gains from trade in a model with oligopolistic competition, heterogeneous firms and innovation. Our key finding is that a trade-induced increase in market concentration can be an important source of the gain...Read more...

Global banking: endogenous competition and risk taking

When banks expand abroad, their riskiness decreases if foreign expansion happens in destination countries that are more competitive than their origin countries. We reach this conclusion in three steps. First, we develop ...Read more...

Technology, market structure and the gains from trade

We study the gains from trade in a new model with oligopolistic competition, firm heterogeneity, and innovation. Lowering trade costs reduces markups on domestic sales but increases markups on export sales, as firms do n...Read more...

Smart but unhappy: independent-school competition and the wellbeing-efficiency trade-off in education

We study whether independent-school competition involves a trade-off between pupil wellbeing and academic performance. To test this hypothesis, we analyse data covering pupils across the OECD, exploiting historical Catho...Read more...

Global banking: risk taking and competition

Direct involvement of global banks in local retail activities can reduce risk-taking by promoting local competition. We develop this argument through a model in which multinational banks operate simultaneously in differe...Read more...

Stagnation traps

We provide a Keynesian growth theory in which pessimistic expectations can lead to very persistent, or even permanent, slumps characterized by unemployment and weak growth. We refer to these episodes as stagnation traps,...Read more...

Dynamic selection: an idea flows theory of entry, trade and growth

This paper develops an idea flows theory of trade and growth with heterogeneous firms. New firms learn from incumbent firms, but the diffusion technology ensures entrants learn not only from frontier technologies, but fr...Read more...

Trapped factors and China's impact on global growth

When China?s accession to the WTO exposed European firms to import competition, they responded by increasing their investment in innovation. This response was stronger in industries and firms where factors of production ...Read more...

The financial resource curse

This paper presents a model of financial resource curse, i.e. episodes of abundant access to foreign capital coupled with weak productivity growth. We study a two-sector, tradable and non-tradable, small open economy. Th...Read more...

Selection Effects with Heterogeneous Firms

We provide a general characterization of which firms will select alternative ways of serving a market. If and only if firms' maximum profits are supermodular in production and marketaccess costs, more efficient firms wil...Read more...

Where is the Economics in Spatial Econometrics?

Spatial econometrics has been criticized by some economists because some model specifications have been driven by data-analytic considerations rather than having a firm foundation in economic theory. In particular this a...Read more...

Efficiency Wages and the Economic Effects of the Minimum Wage: Evidence from a Low-Wage Labour Market

We exploit a natural experiment provided by the 1990 introduction of the UK National Minimum Wage (NMW) to investigate the relationship between wages and monitoring and to test for Efficiency Wages considerations in a lo...Read more...

Technological Diversification

Economies at early stages of development are often shaken by abrupt changes in growth rates, whereas in advanced economies growth rates tend to be relatively stable. To explain this pattern, we propose a theory of techno...Read more...

An R&D-Based Model of Multi-Sector Growth

We develop a multi-sector general equilibrium model in which productivity growth is driven by the production of sector-specific knowledge. In the model, we find that long run differences in total factor productivity grow...Read more...
