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...

Quantification of welfare changes due to trade liberalization plays a crucial role for political decision making. However, significant differences in simulated gains from liberalization do not serve to increase confidence in quantitative assessments based on trade models. A meta-analysis of...

Model-based simulation of welfare effects is commonly used to make a case for trade liberalisation and to inform participants and stakeholders in trade negotiations. However, the simulated welfare effects of trade liberalisation vary greatly, even across studies that model similar liberalisation...

Analysis of price transmission in transition countries is often complicated by unstable policy environments. We use a Markov-switching vector error-correction model (MSVECM) to model multiple regime shifts in the relationship between wheat and wheat flour prices in Ukraine from June 2000 to...

Since the late 1980s, agriculture in Central and Eastern European Countries (CEECs) has been under considerable adjustment pressure due to changing political, economic and institutional environments. These changes have been linked to the transition process, as well as the ongoing integration...

We analyse topics and authorship networks in articles on agricultural transition that were published in 16 subject-related peer-review journals between 1989 and 2008. Increasingly, articles on transition are written by authors from the European Union-15 in collaboration with authors from Central...

It is reasonable to expect that price transmission for perishable products will display seasonal variation, especially in low-income country settings. To date, however, few studies have explicitly tested for seasonal variation in price transmission. We apply a vector error correction model with...

The regulation of seasonal foreign farm labour (SFFL) in Germany distorts market outcomes and produces no significant benefits for any of the affected groups. Analysis of the media discourse on this regulation indicates that its persistence can be attributed to the political sensitivity of...

Estimation of threshold parameters in (generalized) threshold regression models is typically performed by maximizing the corresponding profile likelihood function. Also, certain Bayesian techniques based on non-informative priors are developed and widely used. This article draws attention to...
