Creative destruction through innovation bursts

In theories of creative destruction, product innovation is a key driver of aggregate growth. In this paper, we confront the predictions of these theories about product dynamics with empirical patterns in product-level da...Read more...

Lobbying for globalisation

Using detailed information from lobbying reports filed under the Lobbying Disclosure Act, we construct a unique dataset that allows us to identify which firms lobby on Free Trade Agreements (FTAs) negotiated by the Unite...Read more...

Labor unions and the electoral consequences of trade liberalization

We show that the Brazilian trade liberalization in the early 1990s led to a permanent relative decline in the vote share of left-wing presidential candidates in the regions more affected by the tariff cuts. This happened...Read more...

Political competition and the strategic adoption of free trade agreements

I study how political competition affects the feasibility of free trade agreements (FTAs). I show that the possibility of political turnover creates strategic motivations for the formation of FTAs. Specifically, a govern...Read more...

All aboard: the effects of port development

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...

When tariffs disrupt global supply chains

We study unanticipated tariffs in a setting with firm-to-firm supply relationships. Firms conduct costly searches and negotiate with potential suppliers that pass a reservation level of match productivity. Global supply ...Read more...

Formation of college plans: expected returns, preferences and adjustment process

We exploit a large exogenous shock to study the formation, and updating, of educational plans, and to examine how these plans ultimately impact later educational attainment. Using novel, longitudinal, microdata on cohort...Read more...

How polarised are citizens? Measuring ideology from the ground-up

We investigate whether the ideological polarisation of citizens has increased in Western democracies. We propose a novel methodology to identify individual ideologies by applying Latent Dirichlet Allocation to political ...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...

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...

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...

Revolving Door Lobbyists

Washington's 'revolving door' - the movement from government service into the lobbying industry- is regarded as a major concern for policy-making. We study how ex-government staffers benefit from the personal connections...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...

Entry and Asymmetric Lobbying: Why Governments Pick Losers

Governments frequently intervene to support domestic industries, but a surprising amount of this support goes to ailing sectors. We explain this with a lobbying model that allows for entry and sunk costs. Specifically, p...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...

Information and Communication Technologies in a Multi-Sector Endogenous Growth Model

Trade and Growth with Heterogeneous Firms

This paper explores the impact of trade on growth when firms are heterogeneous. We find that greater openness produces anti-and pro-growth effects. The Melitz-model selection effects raises the expected cost of introduci...Read more...
