Has the CSR engagement of electrical companies had an effect on their performance? A closer look at the environment

Even though electrical companies attain a top ranking in the publication of CSR reports, they are often accused of 'green‐washing' due to their bad environmental reputation. The current economic crisis is testing their real CSR commitment more than ever, especially when this goes beyond its economic consequences. Based on a worldwide sample of electrical companies, we are going to study why companies are being socially responsible. We wish to know if it is due to the impact on the firms' performance or whether there are other motives (legitimation, improving their reputation) that lead companies to carry out these practices. We will also consider if it changes across the kind of CSR action considered. The results show that there is an economic justification beyond the socially responsible behaviour of the electrical companies. Additionally, most kinds of CSR action (community, diversity, corporate governance, product responsibility) are also carried out looking for economic rewards. However, the CSR actions oriented to the environment are mainly motivated by their need to improve their image and reverse their negative impact.

Ranking Crop Yield Models: A Comment

This comment discusses key specification issues that may have affected the performance and, therefore, the ranking of parametric models that were compared in a recent AJAE article. A procedure to obtain the most flexible parametric model specification possible, given the particular probability distribution function on which the model is based is presented. These specifications also allow for standardized and, therefore, more valid comparisons across parametric models that are based on different probability distributions. Finally, the comment cautions against generalization of the rankings in that AJAE article and recommends that these more flexible specifications be adopted in future comparisons and applications.     

Proof of nonparticipation in a price fixing conspiracy

When a group of firms colludes on price, the industry price will rise even when there are some firms that do not participate in the conspiracy. If the government or private parties file antitrust suits, the noncolluders face the problem of establishing their innocence since their prices rise along with those of the colluders. We propose a simple output test. Under various models of oligopoly pricing—Bertrand, Cournot, and Stackelberg—we show that the colluders restrict their output while the noncolluders take advantage of the higher price by expanding their outputs. Thus, distinguishing between colluders and noncolluders involves simply observing the output behavior of the industry members.The authors appreciate the support of the Public Policy Research Center at the University of Florida. We regret that B&R Associates is purely imaginary as is the industry.     

Exploring costs and benefits of compliance with HACCP regulation in the European meat and dairy sectors

A Hazard Analysis and Critical Control Point (HACCP) Program was introduced as a mandatory measure in the EU in the 1990s. Despite its impact on the food industry, only limited literature addresses the issue of cost and benefits of HACCP at the firm level in Europe. This paper illustrates the results of a pilot study on case studies in Italy, UK and The Netherlands, providing a first assessment of the order of magnitude of costs of compliance and a qualitative illustration of the main benefits perceived by producers.     

An estimation of the pattern of diffusion of mobile phones: The case of Colombia

This paper examines the diffusion pattern of mobile telephony in Colombia. The empirical modelling approach adopted in the paper starts off by choosing between the two functional forms that are most frequently used in the literature, namely the Gompertz and the Logistic models. After applying a formal statistical test to choose the preferred functional form, the evidence suggests that the pattern of diffusion can be best characterised as following a Logistic model. The findings also suggest that despite the fact that in recent years the rate of growth of mobile phone subscribers has started to slow down, there still appears to be room for further expansion as the saturation level is expected to be reached in 2013. The estimated saturation level is consistent with some individuals possessing more than one mobile device.     

Collective Choice and Voluntary Provision of Public Goods*

Some public goods are provided entirely with private contributions, others with a mixture of public and private funding, and still others are entirely publicly funded. In order to study this variation, a model of dual provision is developed that endogenizes public and private funding. Households vote over an income tax that finances public supply of the good and on whether to permit private contributions. While permitting private contributions may lead to a reduction in total provision, a majority always favors permitting private contributions. Results are developed for small and large economies, and the relevance of nonexcludability and noncongestion are investigated.     

Drug‐related violence and the decline in the number of Mexican cross‐border workers

This study examines how variations in homicide rates in Mexico are associated with the likelihood of participating in cross‐border work, that is, living in Mexico but working in the U.S. Based on Mexican census data from 2000, 2010, and 2015, and information on homicides, a series of ordinary least squares models are estimated to analyze the relationship between cross‐border commuting and homicide rates at the individual level. Fixed effects models are also estimated to study this relationship at the municipal level. The results show that from 2000 to 2010 the increase in homicide rates in northern border municipalities in Mexico reduced the likelihood of being a cross‐border worker, while from 2010 to 2015 the decrease in the homicide rate increased the probability that workers engage in cross‐border work. The decline in the number of cross‐border workers is likely in part a result of the escalation in drug‐related violence that may have led them to change their country of residence.
