Economists use partial and general equilibrium trade simulation models to estimate the impact of changes in domestic policies and international trade rules. During the WTO Doha Development Agenda (DDA) negotiations economists have produced many different estimates of the gains that would result...

Applied general and partial equilibrium models are widely used tools for ex ante analysis of trade policy changes. However, simulation results seem to exhibit significant variation across publications, and the often criticised ‘black box’ character of applied trade models makes meaningful...

Recent empirical studies argue that the implementation of quality standards among agricultural exporters has the character of a fixed cost. However, this can be misleading if fixed costs are only understood in terms of required investments. Instead, we argue that standard adoption is the result...

In most post-socialist economies, private farming has re-emerged after regime change, although even today this sector most often accounts for only a minor proportion of national production. Russian private farmers are reported to dislike formal cooperatives, so this study investigated whether...

Quantitative partielle- oder allgemeine Gleichgewichtsmodelle stellen in der angewandten Ökonomie ein wichtiges Instrument zur Politikfolgenabschätzung dar. Aus wissenschaftlicher Sicht wird an diesen Modellen ihre mangelnde Transparenz sowie ihre Abhängigkeit von empirisch wenig gesicherten...

Quantification of welfare changes due to trade liberalisation play a crucial role for political decision making. However, meaningful comparisons of simulation results from different sources are difficult. Often significant differences in simulated gains from liberalisation do not serve to...

The global trend of industrializing agriculture increasingly transforms farms and firms into specialized component suppliers within a multi-stage food processing chain, which creates intraindustry trade between- and within geographical regions. This can be analyzed within the framework of a...

Due to the complexity of general and partialequilibrium models, conventional sensitivity analysis,qualitative reviews or literature-based meta-analyses donot allow for detailed assessments of the role ofindividual parameters and policy shocks across differentmodels. Therefore, the partial...
