This paper introduces a simple, yet rich, measure of efficiency changes based on the revenue-generating-ability (RGA) principle. Using this principle, we explain the connections between efficiency changes and the variables, such as pretax profits, interest expense, non-interest expense, profit margins, loan loss provision, and asset quality. These connections are used to explain earnings differences between small and large commercial banks.  相似文献

This article develops a new method of estimating inefficiencies in joint production and shows that unlike the approaches utilized in the previous studies of inefficiency, this method maintains a consistent relationship between the error term of a profit function and the error terms of its price derivatives. A useful by-product of the method is a proof of a Hotelling-like lemma that relates stochastic input demand and output supply functions to stochastic profit functions. While the previous studies fit a single frontier to data on all firms, this paper estimates a frontier unique to every observed firm to allow each one to have a different potential of achieving maximal levels of profit. The new method is applied in the analysis of annual data, 1984–1989, for U.S. commercial banks. Both the analytical and numerical results of the paper show that the residual that the previous studies attribute to inefficiency includes the effects of excluded variables and of inaccuracies in the specified functional forms. Once accurate estimates of these effects are subtracted from the residual, the distortions in the measured inefficiencies should be considerably reduced. Consequently, this article considers how such estimates might be obtained.  相似文献

Using price data collected in Indianapolis and Lafayette, Indiana, rank order correlations between price and quality were computed. These were compared to correlations based on price data obtained from the publications of consumer product testing organizations. It was found that price-quality correlations based on the price data furnished by consumer product testing organizations may not reflect price-quality correlations for specific markets. A second finding of the study suggests the existence of variability across store types with respect to price-quality correlations.  相似文献

This paper describes a research methodology which assesses the efficiency of consumer decision-making based on the types and amounts of informational cues used. A simple operational method is used to classify consumers into three levels of consumer efficiency based on how well they perform in assessing the optimal choice. The information chosen by perfectly efficient consumers, or those scoring at the maximum level of efficiency, is examined for indicators of optimal information seeking and decision-making techniques.  相似文献

Besides classical journalistic products, media users increasingly tend to read texts on the internet published by other users, as in weblogs. How do users navigate among these offers, how do they evaluate the quality, and which standards in terms of media ethics do they apply when reading weblogs compared to newspaper articles? Two empirical studies address these questions. In a survey, 702 internet users rated their theoretical expectations in terms of journalistic quality and compliance with ethical standards, comparing weblogs and daily newspapers. In a consecutive 2 × 2 experimental design, 120 participants read a journalistic text with varying source information (weblog/daily newspaper) and varying degree of adherence to ethical standards (ethically questionable/neutral). Participants then rated the quality of the text and its ethical standards. Results indicate that daily newspapers more than blogs are expected to deliver journalistic quality. But when read, texts are evaluated according to their content rather than their source. Ethically questionable texts in newspapers are disapproved as much as ethically questionable blog postings.  相似文献
