This study examines the effects of direct work experience, gained through internships and cooperative educational experiences, on subsequent knowledge acquisition. In particular, theoretical and empirical research in education, cognitive psychology and accounting suggests that experienced individuals develop organizational knowledge structures which allow them to better assimilate new information into memory than inexperienced individuals. Consistent with this notion, the research investigates whether the benefits of prior direct work experience on knowledge acquisition is a function of the nature of the learning tasks (structured versus unstructured) used in subsequent educational experiences.As hypothesized, the results indicate that inexperienced subjects were assisted to a greater extent in the knowledge acquisition process by structure oriented tax return preparation tasks than by relatively unstructured tax research assignments. Also consistent with expectations, the opposite was true for experienced subjects. When experienced subjects were provided with instruction supplemented by unstructured tax research assignments, they demonstrated a greater level of tax knowledge than when assigned structured tax return problems. Further, the knowledge level of experienced subjects was found to be greater than that of inexperienced subjects only when unstructured tax research assignments were provided. These findings suggest that all benefits of direct work experience on the knowledge acquisition process cannot be realized without the specific consideration of such experiences on the design of educational and firm training materials. Finally, the study also indicates that the benefits of direct work experience on subsequent knowledge acquisition are generally greater for individuals with low versus high learning aptitudes. 相似文献

This paper investigates the relationship between R&D and corporate performance. The study extends previous research by examining the conditions under which firms benefit from R&D; by incorporating in the analysis the varying costs of R&D inputs; and by employing an opportunity-cost approach that estimates the monetary returns to R&D. The findings indicate that industrial research generates revenues that are significantly higher than the returns that other investments yield. The study also resolves previously conflicting results concerning firm size, and offers new insights on the role of technological opportunities that contradict past studies. Although the potential for innovation is greater in high-tech industries, intense R&D competition prevents technologically dynamic firms from enjoying high returns to R&D. By contrast, the results demonstrate that low-tech firms use R&D successfully as part of their strategies, implying that prior research underestimates the importance of R&D for these firms. 相似文献

The establishment of a new preferential trade agreement (PTA) or the expansion of an existing one alters the incentives of non-members to participate in a PTA. This can lead to a domino effect whereby non-members join an existing PTA. Or it can lead a pair of countries to establish a new PTA. We examine the determinants of why a pair of countries enters a bilateral PTA. Our emphasis is on (a) the impact of pre-existing PTAs and (b) whether this impact is larger when the members of pre-existing PTAs are on average geographically close to the pair of countries. Using data for 145 countries during 1955-2005, we find evidence that pre-existing PTAs increase the probability that a country-pair will enter a bilateral PTA and that this effect diminishes with distance. The analysis makes use of techniques drawn from spatial econometrics. 相似文献

In this paper the economies of scale arising from the acquisition of costly information and their implications for the existence of a competitive equilibrium are investigated. As is known, the existence of economies in the scale of production undermines the possibility of a competitive equilibrium. This paper demonstrates that this kind of problem arises when firms face market uncertainty, i.e. in competitive markets, uncertainty about the price of production factors or about the price of output. It is shown that, under these circumstances, firms have incentives to purchase market information, i.e. information capable of reducing price uncertainty. In turn, the acquisition of costly information generates economies of scale that prevent the occurrence of a competitive equilibrium, unless such increasing returns to scale are tamed by the decreasing utility of uncertain returns due to risk aversion, or—in the short run—by increasing marginal costs of production. 相似文献

This article examines the evolution of social security research from a theoretical and empirical perspective. This is done through an extensive review and analysis of publications from the Journal of International Social Security Review published by Wiley within a 50-year period (1967–2017). It was observed that at a different period in time, the social security research focused on different national and international issues that invoked different social welfare programs and pension systems approach (public or private) to facilitate the explanation of its final socio-economic impact into different social groups in the same country or region respectively. 相似文献

Getting a clear sense of the intensity and dynamics of corruption in a society or country is a critical platform for economic growth and development. This paper sets out to bring clarity to the study of corruption through an alternative approach. It examines and demonstrates how corruption can be evaluated by basically hinging it on the socio-economic development deaccumulation that any country can experience in different historical periods. The paper presents the socio-economic development desgrowth index (Ð-index), a new indicator with a complete set of mathematical tools that capture and calculate all the aspects that encompass corruption within a system or country. The paper successfully applied the (Ð-index) to X-ray the successive administrations of Guatemala from 1986 to year 2016 from where we convincingly observed the highs and lows in the corruption dynamics of Guatemala. 相似文献

Previous research has shown a detrimental effect of low task meaning on individual work output. This paper analyzes whether peer settings are able to counteract this negative effect of low task meaning. First, our results confirm that a low level of task meaning decreases individual output when working alone. However, this effect vanishes completely when working in the presence of a peer. Our analysis implies that organizing work in peer settings might be particularly beneficial in work environments with a low level of task meaning. 相似文献

Since the first commercial cultivation of genetically modified crops in 1994, the rapidly expanding market of genetically modified seeds has given rise to a multibillion dollar industry. This fast growth, fueled by high expectations towards this new commercial technology and shareholder trust in the involved industry, has provided strong incentives for further research and development of new genetically modified plant varieties. Considering, however, the high financial stakes involved, concerns are raised over the influence that conflicts of interest may place upon articles published in peer-reviewed journals that report on health risks or nutritional value of genetically modified food products. In a study involving 94 articles selected through objective criteria, it was found that the existence of either financial or professional conflict of interest was associated to study outcomes that cast genetically modified products in a favorable light (p = 0.005). While financial conflict of interest alone did not correlate with research results (p = 0.631), a strong association was found between author affiliation to industry (professional conflict of interest) and study outcome (p < 0.001). We discuss these results by comparing them to similar studies on conflicts of interest in other areas, such as biomedical sciences, and hypothesize on dynamics that may help explain such connections. 相似文献

The US Department of Agriculture applies a cost-of-illness approach to value reductions in morbidity, which may understate the projected benefits from proposed food-safety improvements by ignoring costs such as pain, suffering and worry. We use a national survey with a hypothetical food-choice experiment to estimate a more comprehensive measure of consumer willingness-to-pay for food-safety improvements. Our approach differs from previous evaluations of food-safety improvements because we: (1) provide the respondent with information about the promised change in the probability of pathogen contamination in retail food packages rather than changes in the probability of becoming ill, (2) elicit changes in respondents’ subjective probability of becoming ill, and (3) elicit predicted changes in the quantity demanded for products that have enhanced food-safety properties. We estimate the consumer’s choice between a safety-enhanced and an existing product, the change in subjective probability of contracting foodborne illness associated with the enhanced product and the change-in-demand for the enhanced product in a manner that recognizes the correlation among unobserved elements. The aggregated results suggest benefit estimates that are significantly larger than previous estimates for similar improvements. 相似文献

In the continuing stagnation of European economies, the persistence of inadequate demand plays a crucial role that deserves greater attention. First and foremost, we are in a context of slower international growth, in which global world trade is growing more slowly than global GDP. This implies that exports are not in the position to be the driver of renewed growth for Europe. 相似文献
