This empirical application investigates the eventual presence of credit constraints using a panel of French farmers. The credit-constrained profit maximization model proposed by Färe, Grosskopf, and Lee is extended in three ways. First, we rephrase the model in terms of directional distance functions to allow duality with the profit function. Second, we model credit constraints in the short-run and investment constraints in the long-run using short- and long-run profit functions. Third, we lag the expenditure constraint one year to account for the separation between planning and production. We find empirical evidence of credit and investment constraints. Financially unconstrained farmers are larger, perform better, and seem to benefit from a virtuous circle where access to financial markets allows better productive choices. 相似文献

Trends in the literature on socially responsible investment: looking for the keys under the lamppost
In this paper, we use online search engines and archive collections to examine the popularity of socially responsible investing (SRI) in newspapers and academic journals. A simple content analysis suggests that most of the papers on SRI focus on financial performance. This profusion of research is somewhat puzzling as most of the studies used roughly the same methodology and obtained very similar results. So, why are there so many studies on SRI financial performance? We argue that the academic literature on SRI is mostly data driven: the famous ‘looking for the keys under the lamppost’ syndrome. The question of the financial performance of the SRI funds is certainly relevant but maybe too much attention has been paid to this issue, whereas more research is needed on a conceptual and theoretical ground, in particular the aspirations of SRI investors, the relationship between regulation and SRI as well as the assessment of extra‐financial performances. 相似文献
