A large class of models with CES utility and iceberg trade costs are now known to generate isomorphic “gravity equations.” Economic interpretations of these gravity equations vary in terms of two basic elements: the exporter's “mass” variable and the elasticity of trade with respect to...

The large reduction in tariff rates worldwide under several rounds of the GATT is commonly credited with being one of the most notable economic policy accomplishments since World War II. However, the remarkable progress towards free trade of goods is unparalleled in trade with services where...

This paper develops a structural empirical general equilibrium model of aggregate bilateral trade with path dependence of country-pair level exporter status. Such path dependence is motivated through informational costs about serving a foreign market for first-time entry of (firms in) an export...

Heterogeneous firms invest in R&D and expansion investment. Venture capital specializes in R&D financing where problems are largest. Marginal firms get funded by venture capital, while firms with larger debt capacity obtain cheaper bank financing. In the latestage, cash-rich firms invest at an...

Structural new trade theory models have never been used to evaluate and quantify the role of preferential trade agreement (PTA) membership for trade in a way which is consistent with general equilibrium. Apart from filling this gap, the present paper aims at delivering an empirical model which...

This article presents first insights into the role of international outsourcing on the productivity of low-skilled workers in EU manufacturing. Whereas in the short run international outsourcing exhibits a negative marginal effect on real value added per low-skilled worker, the long-run...

We argue that the proper specification of a panel gravity model should include main (exporter, importer, and time) as well as time invariant exporter-by-importer (bilateral) interaction effects. In a panel of 11 APEC countries, the latter are highly significant and account for the largest part...

The measurement of trade costs and their effects on outcome is at the heart of a large quantitative literature in international economics. The majority of the recent significant contributions on the matter assumes that trade consists of a product of exporter-time-specific factors,...

Many empirical gravity models are now based on generalized linear models (GLM), of which the Poisson pseudo-maximum likelihood estimator is a prominent example and the most-frequently used estimator. Previous literature on the performance of these estimators has primarily focussed on the role of...
