Firms face competing needs to expand product variety and reduce production costs. Trade policy affects firm investments … recapture these lost markups. I provide a theory detailing this conflicting impact of trade policy and address welfare gains … from trade. Accounting for firm heterogeneity, I show support for the theoretical predictions with firm-level innovation …

Competing for Contacts: Network Competition, Trade Intermediation and Fragmented Duopoly

Petropoulou, Dimitra - Centre for Economic Performance, LSE - 2008

A two-sided, pair-wise matching model is developed to analyse the strategic interaction between two information intermediaries who compete in commission rates and network size, giving rise to a fragmented duopoly market structure. The model suggests that network competition between information...

Intra-Industry Foreign Direct Investment

Alfaro, Laura; Charlton, Andrew - Centre for Economic Performance, LSE - 2007

We use a new firm level data set that establishes the location, ownership, and activity of 650,000 multinational subsidiaries—close to a comprehensive picture of global multinational activity. A number of patterns emerge from the data. Most foreign direct investment (FDI) occurs between rich...

Further Simulation Evidence on the Performance of the Poisson Pseudo-Maximum Likelihood Estimator

Silva, J. M. C. Santos; Tenreyro, Silvana - Centre for Economic Performance, LSE - 2009

We extend the simulation results given in Santos-Silva and Tenreyro (2006, 'The Log of Gravity', The Review of Economics and Statistics, 88, pp.641-658) by considering data generated as a finite mixture of gamma variates. Data generated in this way can naturally have a large proportion of zeros...

Convergence of Firm-Level Productivity, Globalisation, Information Technology and Competition: Evidence from France

Chevalier, Paul-Antoine; Lecat, Rémy; Oulton, Nicholas - Centre for Economic Performance, LSE - 2009

Studies of firm-level data have shown that there is a huge dispersion of productivity across firms even when industries are narrowly defined. So there is a significant opportunity for the least productive firms to catch up to the most productive. The formers' convergence could therefore...

On the Existence of the Maximum Likelihood Estimates for Poisson Regression

Silva, J. M. C. Santos; Tenreyro, Silvana - Centre for Economic Performance, LSE - 2009

We note that the existence of the maximum likelihood estimates for Poisson regression depends on the data configuration. Because standard software does not check for this problem, the practitioner may be surprised to find that in some applications estimation of the Poisson regression is...
