Random parameters demand system estimates can generate upward sloping demands and imply margins outside of the theoretical bounds for profit maximization. If such violations are numerous enough, they can confound merger simulation exercises. Using Lerner indices for multiproduct firms playing static Bertrand games, we find that up to 35 per cent of implied margins for beer are outside the bounds. We characterize downward sloping demand and the theoretical bounds for profit maximization as prior information and extend the GMM objective function, incorporating inequality moments for product‐level own‐elasticities and brand level or product level Lerner indices. Very few violations remain when an inequality constrained estimator is used. 相似文献

Measuring rural consumers’ willingness to pay for quality labels using experimental auctions: the case of aflatoxin‐free maize in Kenya 下载免费PDF全文

Aflatoxins are a common health hazard in tropical countries, especially in rural areas. New methods to reduce aflatoxin levels in food staples, as well as cheaper test methods, are being developed, but consumers’ willingness to pay (WTP) for these improvements is unknown. A survey was conducted with a representative sample of rural consumers (1,344 in total, 63% women) in all major maize‐production zones of Kenya. The survey included an experimental auction with maize products of different qualities. The results showed that many rural consumers were aware of aflatoxins, but few understood their health risks. Respondents were willing to pay a premium for maize tested for aflatoxins and labeled, but asked a high discount for maize that was visibly contaminated with moldy grain. The premium was higher for respondents with education and in regions with aflatoxicosis outbreaks. Knowledge of aflatoxins substantially reduced the overall WTP, but did not increase the WTP for tested maize. Welfare analysis indicates that mandatory testing would result in substantial benefits if the cost of testing can be lowered to below the premium. 相似文献

The aim of this article is to examine the impact of stock exchange mergers on the degree of informational efficiency. For this purpose, we apply the generalized spectral shape test for the martingale difference hypothesis to the stock returns before and after the 31 domestic and cross-border mergers completed from 1997 to 2011. The test is conducted with moving subsample windows, allowing us to detect the periods of (in)efficiency, and thus to conduct a comparative analysis for pre-merger and post-merger periods. We find that higher levels of efficiency are less frequent than lower levels of efficiency after a stock exchange merger. We also find that the impact on the level of efficiency depends on a range of merger characteristics such as the level of development, size, geographical diversification and industrial diversification of stock exchange. 相似文献

In this paper, we analyze the determinants of corporate saving in the form of changes in cash holdings for 11 Asian economies using firm‐level data from the Oriana Database for the 2002–2011 period. We find some evidence that cash flow has a positive impact on the change in cash holdings (i.e. that the cash flow sensitivity of cash is positive) and that the positive impact of cash flow on the change in cash holdings is larger and more significant in the case of smaller and presumably more constrained firms than in the case of larger and presumably less constrained firms in both developed and developing economies. Both of these findings corroborate the importance of financial constraints in Asian firms. In addition, we find that the cash flow sensitivity of cash declined after the global financial crisis and that Tobin's q has a positive impact on the change in cash holdings, especially in the case of larger and presumably unconstrained firms. 相似文献

The authors investigate institutional productivity in business and management education (BME) research based on the analysis of 4,464 articles published by 7,210 authors across 17 BME journals over a 10-year period, involving approximately 1,900 schools worldwide. Departing from traditional disciplinary silos, they examine the BME research field as a whole by including all traditional business disciplinary areas and producing two top 100 rankings, one based on raw number of author publications and the other based on weighted scores reflecting journal quality and coauthorship. 相似文献

Portrayals of women and minorities advertising have long been of interest to advertising scholars. While research has found that the overall representation of these groups has increased, some stereotypes persist, and so do questions about the quality and prominence of portrayals. This study examines portrayals of minorities and women in Super Bowl advertising, the main “pop culture” showcase for US advertising. A content analysis of 10 years of Super Bowl ads is conducted and a multinomial logit regression model is employed to delve deeper into the content analysis results. Findings show that while the overall representation of women and various minority groups is strong, a deeper analysis shows that these groups are seldom depicted as primary characters by themselves and that some subtle stereotypes persist. We also find that ads featuring female principal characters are more likely to feature home settings, sexual appeals, emotional messages, and music as a major element and that it is less likely for female (vs. male) celebrities to be used. Minority principal characters are more likely to be celebrities and be included in ads with music or for technical products but are less likely to be included in ads featuring corporate social responsibility messages. 相似文献
