This paper studies the impact of NAFTA on informality and real wages in Mexico. Using a dynamic industry model with firm heterogeneity, it is predicted that import tariff elimination could reduce the incidence of informality by making more profitable to some firms to enter the formal sector,...

This chapter discusses whether and how .new quantitative trade models.(NQTMs) can be fruitfully applied to quantify the welfare effects of trade liberalization, thus shedding light on the trade-related effects of further European integration. On the one hand, it argues that NQTMs have indeed the...

In Brazil, gasoline and ethanol coexist as automotive fuels and are becoming closer substitutes as flex cars become more widely adopted. We employ this source of variation in a large panel of weekly prices at the station level to show that fuel prices have fallen in response to this change. This...

The impacts of choice in public services are controversial. We exploit a reform in the English National Health Service to assess the impact of relaxing constraints on patient choice. We estimate a demand model to evaluate whether increased choice increased demand elasticity faced by hospitals...

Interconnection rates are a key variable in telecommunications markets. Every call that is placed must be terminated by the network of the receiving party, thus the termination end has the characteristic of an economic bottleneck and is subject to regulation in many countries. This paper...

Has the introduction of greater choice and competition in healthcare in England led to improved outcomes for patients? The authors assess changes in the quality of care that hospitals provided for cardiac surgery patients following the mid-2000s reforms.

This paper tests for the importance of cash flow on investment in fixed capital and R&D using firm-level panel data in two countries between 1985 and 1994. For German firms, cash flow is not informative in simple econometric models of fixed investment or R&D. In identical specifications for...

Unilateral minimum quality standards are endogenously determined as the outcome of a non-cooperative standard-setting game between the governments of two countries. Cross-country externalities from the implementation of minimum quality standards are shown to give rise to a Prisoners' Dilemma...

When firms cluster in the same local labor market, they face a trade-off between the benefits of labor pooling (i.e., access to workers whose knowledge help reduce costs) and the costs of labor poaching (i.e., loss of some key workers to competition and the indirect effect of a higher wage bill...

This paper analyzes differences in R&D spending and in the impact of R&D on productivity between German and UK firms. We confirm that German firms spend significantly larger amounts on R&D than their UK counterparts, even after controlling for firm size and industry effects. Using a dynamic...
