This article studies the determinants of box-office revenues in the motion picture industry. We first adopt an approach that takes into account quality signals (e.g. talent concentration, movie budget and Oscar awards, among others) to analyse the empirical relationship between category-specific parenthood ratings (R-ratings) and box-office revenues. Then, by matching movie contents with economic performance records, our original approach reveals that offensive contents like profanity or nudity may be a hindrance to achieve economic returns, while violent contents seems to enhance box-office revenues. Further research is needed to clarify the interaction in this regard between production budget and movie contents.  相似文献

Genetically modified (GM) crops are popular in many regions of the world, but their deployment in Africa is hindered by safety concerns and regulatory issues, although the continent is in dire need of boosting its food production. Although consumers' acceptance of GM food has been analyzed in many continents, no such studies have been conducted in Africa. Therefore, a survey of 604 consumers was conducted in Nairobi, Kenya, in 2003, to gauge consumers' awareness of GM crops, their willingness to pay (WTP) for GM food, and the factors that influence their WTP. Consumers' knowledge of GM crops was limited and only 38% of the 604 respondents were aware of GM crops. People in higher education and income groups were more aware than others. Regardless, people were generally appreciative of the technology, and a large majority (68%) would be willing to buy GM maize meal at the same price as their favorite brand. Consumers were, however, concerned about possible side effects, especially on the environment and biodiversity. WTP was estimated using a double‐bounded dichotomous choice model, and the mean WTP was found to be 13.8% higher than the average price of non‐GM maize meal. Perceptions of health risk, and ethical and equity concerns had a negative influence on the likelihood of purchasing GM maize meal, whereas trust in government to ensure food quality had a positive influence on WTP. People with at least some secondary education and those in the high‐income category were more likely to purchase GM maize meal at the same price. The study concludes that, because awareness is still low, appropriate communications are needed to involve the consumer in the debate. Consumers' acceptance in this study was high, but the research needs to be expanded to rural areas, where most consumers live, and other survey methods need to be explored.  相似文献

Viagra can rather obviously be termed "techno-romantic"--literally it is a technology to make sex possible. But technoromanticism is also a philosophical term referring to the belief that advances in technology serve "truth" "unity" and "wholeness" according to Coyne (1999). Surprisingly many pharmaceutical companies seem to have developed "Viagra" or at least substances that were very similar, but to have ignored and/or rejected commercializing them. This article assumes that the primary activity of research and development in pharmaceutical companies is to produce texts that interpret chemicals as "meaningful." Assumptions of what constitutes (medical) meaning within prevailing technoromanticism have seen R and D as a form of "production" that demands rejection of "consumption." This technoromanticism succeeded in rebuffing the sexual "techno-romanticism" of Viagra in the company studied, but Viagra's enormous commercial success has reversed priorities. R and D's meaning system has proven to be no match for Viagra-ization--the article examines the resulting crisis in meaning systems.  相似文献

The conceptualization of assets and liabilities is fundamental to an understanding of financial accounting. It is often maintained that assets and liabilities represent economic resources and economic obligations, respectively, but that not all economic resources are assets and not all economic obligations are liabilities — a somewhat confusing state of affairs. This paper presents a schema for distinguishing assets from economic resources and liabilities from economic obligations based on the authoritative literature in the United States, Australia, Canada and Great Britain. The schema should be useful for clarifying certain financial accounting controversies concerning income taxes, leases, pension benefit payments and executory contracts.  相似文献

A new measure of factor intensity and abundance from trade theory is utilized to predict potential trade and income redistribution between traditional and modern economies in the Gulf Cooperation Council. Differences in labor skill intensity and abundance suggest there will be substantial trade between the modern (Bahrain, Qatar, UAE) and traditional (Kuwait, Oman, Saudi Arabia) economies in the GCC. Due to the limited data, the UAE and Kuwait are taken to represent the modern and traditional economies.  相似文献

In Mexico, the low participation of insurance activity in national production, in contrast to similar Latin American economies, is a concern. Industry’s regulator promoted more intense competition at the dawn of the century. Was deregulation followed by improvements in the financial and economic performance of Mexican insurance firms? The purpose of this paper is to answer this question through a comprehensive analysis of cost variations in an intertemporal manner, by breaking them down into the economic sources that produce them, including productivity. Cost frontier estimation was grounded in a joint production technology of desirable and undesirable outputs, modeled in an input-oriented fashion. Our results demonstrate that even though some companies achieved cost reductions from technological progress or improvements in efficiency, the Mexican insurance market does not show signs of significant productivity gains.  相似文献

Cai and Shintani (2006, Econometric Theory, 22, 347–372) considered the impact of introducing an inconsistent long‐run variance estimator when constructing a class of kernel‐based ratio tests for testing non‐stationarity in the series. They found that the quotient of two estimators with different rates of convergence under the null and the alternative hypotheses may lead to a test having an interesting size and power trade‐off. This paper develops modified versions of this test, presents new asymptotic results and tabulates critical values. The finite sample performance is explored through Monte Carlo simulations. The results show that the modifications proposed lead to more powerful unit root tests.  相似文献
