Explaining the size differences of exporter premia: theory and evidence

Two decades of research have established pronounced exporter productivity premia (EPP) and exporter size premia (ESP). Yet, we do not know why such exporter premia differ so widely in magnitude across countries or sectors? We take this question to the theory and to the data. We derive the sectoral EPP and ESP in a standard heterogeneous firms trade model and apply the insights from the model to guide our empirical investigation of detailed Danish firm-level data. We show that a significant share of the observed variation in EPP and ESP across sectors can be accounted for by sector differences in the underlying variation in productivity dispersion, variable trade costs, the ratio of fixed export costs to fixed costs of production, and the elasticity of demand.     

Können Fiskalräte die europäische Schuldenkrise lösen?

This article analyses the role of independent fiscal institutions (IFIs) in dealing with the debt crisis in Europe. IFIs take the role of a fiscal watchdog by producing their own (or assessing the government’s) budget and macroeconomic forecast and have recently spread across many industrialized countries. Empirical evidence suggests that IFIs can contribute to solid public finances in conjunction with fiscal rules if these institutions are truly independent, have a clear mandate and access to sufficient resources, as well as a strong media impact.     

The IMF and the countries of the Council for Mutual Economic Assistance

In November 1981 Hungary and, one week later, Poland applied for membership of the International Monetary Fund (IMF) and the International Bank for Reconstruction and Development (World Bank). These applications have highlighted a subject which had been neglected for quite some time. This analysis deals with the problems and consequences which arise from the membership of countries of the Council for Mutual Economic Assistance (Comecon)—the economies of which largely conform to principles of central economic planning—in IMF, an institution organized according to market principles.     

Firm exit,technological progress and trade

The dynamics of export market exit and firm closure have found limited attention in the new heterogeneous-firms trade literature. In fact, several of the predictions on firm survival and exit stemming from this new class of models are at odds with the stylized facts. Empirically, higher productivity firms survive longer, most firm closures are young firms, higher productivity exporters are more likely to continue to export compared to less productive exporters and market exits as well as firm closures are typically preceded by periods of contracting market shares. The present paper shows that the simple inclusion of exogenous economy wide technological progress into the standard Melitz (2003) model generates a tractable dynamic framework that generates endogenous exit decisions of firms in line with the stylized facts. Furthermore, we derive the effects of faster technological progress and trade liberalization on export market exit and firm closure.
