Are EU spatial ex ante coexistence regulations proportional?
No full textThe EU is currently struggling to implement coherent coexistence regulations on genetically modified (GM) and non-GM crops in all member states. While it stresses that any approach needs to be “proportionate to the aim of achieving coexistence”, very few studies have actually attempted to assess whether the proposed spatial ex ante coexistence regulations (SEACERs) satisfy this proportionality condition. In this article, we define proportionality as a functional relationship which is weakly increasing in the incentives for coexistence. We propose a spatial framework based on an existing landscape and introduce the new concept of shadow factor as a measure for the opportunity costs induced by SEACERs. This enables comparing the proportionality of (i) rigid SEACERs which are based on large isolation distances imposed on GM farmers versus (ii) flexible SEACERs based on pollen barrier agreements between neighboring farmers. Our theoretical and empirical findings argue for flexibility as rigid SEACERs violate the proportionality condition and, hence, are not consistent with the objectives of the EU.policy analysis, GIS, shadow factor, Agricultural and Food Policy, Crop Production/Industries,
Risk and De-Collectivisation: Evidence from the Czech Republic
No full textThe replacement of wage-labour farms by family farms in Central and Eastern Europe during the transformation has been more limited than was initially expected. In this paper a formal framework is developed in order to analyse the behaviour of family farms and socialist-style farms in the presence of risk, given the typical post-socialist environment. Management incentives, ownership structure, lump-sum transfers and consumption choices are shown to have the potential to limit the size of family farms relative to socialist-style farms. The hypotheses are tested with survey data collected by the author in the Czech Republic.transition, agriculture, structural change, risk, survey data, Risk and Uncertainty, D21, D81, O18, Q12,
Option Predictability and Corporate Events: Origins of the Information Advantage on Stock Prices
No full textTo be awarded, or Not to Be Awarded. Is that the Question?:Theoretical and Methodological Aspects of the Study of Literary and Translation Prizes in the Context of Cultural Transfer
No full textTo be awarded the Nobel Prize in Literature or not to be awarded. Is that the question? Is not every author overwhelmed by the mere thought of being awarded the Noble Prize in Literature? After all, it means more translations, a broader audience, honour, money and fame. One good example of a writer who benefitted from the prize is the Icelandic author Halldór Laxness (1902-1998). A hitherto unknown poet and novelist, he became world famous after receiving the award in 1955, after which his works were translated into more than 25 languages.1 There have also been authors, however, who were anything but honoured to be nominated. Undoubtedly, the most famous example is Jean-Paul Sartre (1905-1980), who refused the Nobel Prize in 1964 to maintain his intellectual credibility as an anti-bourgeois philosopher and activist
