The reforms led to productivity growth and helped China to pursue its self-sufficiency goal especially in the grain sector. In order to analyze whether observable productivity growth stems from technologically induced components or from the market induced parts, a multi-input–multi-output model is derived by using an econometric distance function framework. A decomposition allows to distinguish allocative effects, scale effects, technological change, and technical efficiency change. Data on farms in Zhejiang from 1986 to 2000 are used to analyze the impact of policy reform."],["dc.identifier.doi","10.1016/j.jdeveco.2005.04.009"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/11907"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.relation.doi","10.1016/j.jdeveco.2005.04.009"],["dc.title","Policy reform and productivity change in Chinese agriculture: A distance function approach"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dspace.entity.type","Publication"]]

This paper analyses the domestic market impact of wheat export controls in Russia and Ukraine during the 2007/2008 global food crisis within a spatial price transmission approach. Using a Markov-switching vector error-correction model, we contrast our estimation for Russia and Ukraine with Germany and the USA, two countries that did not intervene in their wheat export markets. An explicit “crisis” regime during times of export controls is exclusively identified for Russia and Ukraine. We find that export restrictions temporarily reduced the degree of integration of Russian and Ukrainian domestic markets in world wheat markets, which pushed the growers prices below their long-run equilibrium level. Further, domestic markets were disconnected from their equilibrium and market instability increased. These effects were even more pronounced and long lasting in Ukraine (export quota) than in Russia (export tax). The negative market effects discouraged private investors, thereby preventing Russia and Ukraine from maximizing their grain potential and contributing to global food security. Highlights ► We focus on export controls and the price link between domestic and world markets. ► We contrast our estimation for Russia and Ukraine with Germany and the USA. ► Export controls reduced integration of domestic in world wheat markets temporarily. ► Growers prices decreased below the long-run equilibrium and instability increased. ► Our results suggest long-lasting effects in the case of Ukraine."],["dc.identifier.doi","10.1016/j.foodpol.2012.12.001"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/11560"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.title","Wheat export restrictions and domestic market effects in Russia and Ukraine during the food crisis"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dspace.entity.type","Publication"]]
