Explaining the puzzling persistence of restrictions on seasonal farm labour in Germany
研究了德国季节性外国农业劳动力监管的持续原因，发现失业等政治敏感因素导致媒体话语的结构性断裂，从而解释了该限制的持久性。
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 unemployment and related issues in Germany. To reach these conclusions, we propose a new method for the analysis of discourse data based on a Poisson change point model, and demonstrate that exogenous factors such as unemployment in Germany can explain structural breaks in the media discourse on SFFL in Germany. , Oxford University Press.
