Recently gravity trade models are applied to disaggregated trade data. Here manyzeros are characteristic. In the presence of excess zeros usual Poisson Pseudo MaximumLikelihood (PPML) is still consistent, the variance covariance matrix howeveris invalid. Correct economic interpretation however...

This paper investigates the impacts of export controls in Russia and Ukraine on wheat world market price transmission during the 2007/2008 global food crisis. Russia and Ukraine aimed to reduce wheat exports induced by extraordinarily high world market prices to secure sufficient wheat supply on...

One of the most important targets ofthe Common Agricultural Policy (CAP) is to facilitatethe spatial integration of agricultural markets within theindividual member states as well as within the Community.On a spatially integrated market, price informationshould freely flow between member states....

Against the background of the Middle East conflict we study the role of social embeddedness of economic actors belonging to both conflicting parties for their perceptions of transaction problems and capabilities to solve them. Our analysis is based on a quantitative survey among Israeli food...

Over the last decade, major shifts have occurred in international wheat trade. On the supply side, Russia, Ukraine and Kazakhstan emerged as important wheat exporters and Russia is even projected to displace the United States as the leading exporter by 2021. We analyze the pricing behavior of...

The field of price transmission is dominated by econometric time-series analysis (PTA) and rather disconnected from analyses based on CGE models. This paper addresses how a certain degree of empirically determined price transmission can be met in a single country CGE model. We examine and...
