This paper studies the impact of foreign labour on the competitiveness of Italian dairy farms relying on the theory of foreign labour in profit functions. Application of an endogenous switching regression model identifies the drivers of adoption of the immigrant workforce. A counterfactual analysis performed on unit labour costs between farms employing and non-employing immigrants suggests the essential role of foreign farmworkers on dairy farms’ competitiveness, which provide a cheaper source of labour. The lower unit labour cost for immigrant workers resembles staunch support to the newly introduced ‘social conditionality’, for a CAP delivering also for farmworkers.

竞争力签证：外国劳动力和意大利奶牛场的表现

本文借助外来劳动力的利润函数理论，研究外来劳动力对意大利奶牛场竞争力的影响。内生转换回归模型的应用确定了采用移民劳动力的驱动因素。对雇佣和非雇佣移民的农场之间的单位劳动力成本进行的反事实分析表明，外国农场工人对奶牛场竞争力的重要作用，这提供了更便宜的劳动力来源。移民工人的较低单位劳动力成本类似于对新引入的“社会条件”的坚定支持，因为 CAP 也为农场工人提供。
