This paper presents a model of trade that explains why firms wait to export and why many exporters fail. Firms face uncertain demands that are only realized after the firm enters the destination. The model retools the timing of the resolution of uncertainty found in models with heterogeneity of firm productivity. This retooling addresses several shortcomings. First, the imperfect correlation of demands reconciles the sales variation observed in and across destinations. Second, since demands for the firm's output are correlated across destinations, a firm can use previously realized demands to forecast unknown demands in untested destinations. The option to forecast demands causes firms to delay exporting in order to gather more information about foreign demand. Third, since uncertainty is resolved after entry, many firms enter a destination and then exit after learning that they cannot profit. This prediction reconciles the high rate of exit seen in the first years of exporting. Finally, when faced with multiple destinations to which they can export, many firms will choose to sequentially export in order to slowly learn more about its chances for success in untested markets. 相似文献

The study is based on the hypothesis that there is a link between corruption and underdevelopment and that corruption is responsible for the shortcomings and poor performance of the Nigerian political economy. In addition to examining the historical trajectory of corruption in Nigeria, this paper delves into the underlying causes of corruption as well as its cumulative impact on national development in the country. Lastly, the paper assesses some public and private sector initiatives that have been taken and that might stem the tide of corruption. 相似文献

The Tipping Point of Design: How Product Design and Brands Interact to Affect Consumers’ Preferences
Existing research on product design has demonstrated the importance of aesthetics in generating favorable consumer responses. However, the literature has only recently begun to explore if and to what extent the impact of product design is influenced by brand strength. Whereas some research indicates that strong brands may benefit less strongly from aesthetically attractive designs, other research suggests that attractive designs are more persuasive when they are paired with a strong brand. In this research, these two competing predictions were tested through three studies with German car buyers. In Study 1, participants were exposed to a fictitious car that was paired with a randomly chosen brand name. In Study 2, participants were presented with a set of existing cars and were asked to choose one. Both studies yield converging evidence and show that product design and brands interact in a positive fashion, suggesting that attractive designs exert a greater influence on consumers’ decision processes when they are accompanied by a strong brand. Study 3 extended these findings by demonstrating that strong brands only increase the impact of attractive designs when perceived risk is high but not when it is low. 相似文献

The food sector has taken on an unprecedented dynamism in recent years. The processing and distribution of food, although heavily influenced by tradition, have seen intensive innovations, leading to changes in the way individuals consume. One of these changes is the consistent growth of the habit of eating outside the home. Consuming food outside the home involves a number of practices such as eating at commercial establishments that specialize in food (restaurants, fast food restaurants and snack bars) and those that offer food as a part of their services (hotels, in‐flight meals), and non‐commercial alternatives such as the homes of family and friends. In order to describe the eating habits of consumers in the town of Lavras in Minas Gerais State, Brazil, especially when it comes to eating outside the home, a quantitative study was conducted, with 413 questionnaires being distributed by convenience sampling. Among the main results are: (a) a search for variety as a motivator for eating outside the home; (b) convenience as an important element on many occasions of consumption; (c) more intensive consumption and more favourable attitudes towards eating out on the part of younger people, people with higher incomes, no children and a higher degree of schooling; (d) importance of paying for food by the kilo. When compared with a study conducted in England, important similarities were identified in socio‐demographic influences, although the cultural factors are notable when it comes to dishes and the types of eating establishment. The growing habit of eating out has therefore become a worldwide phenomenon, but with cultural and regional differences that have led to different rhythms in terms of change and the way food is supplied. The recovery of embedded cultural habits, with increased value being given to slow food, traditional dishes and tradition itself, appears to co‐exist with a productivity model of food courts, pasteurization and accessible prices. The occasion for consumption, which may be understood as the dichotomies of ‘weekday versus weekend’ or ‘convenience versus leisure’, is an important element that influences consumer behaviours. The undertaking of a cross‐cultural comparative study can be seen as an important step in this field of research. 相似文献

Though most traditional HR performance metrics don't predict organizational performance, alternatives simply have not existed--until now. During the past ten years, researchers Laurie Bassi and Daniel McMurrer have worked to develop a system that allows executives to assess human capital management (HCM) and to use those metrics both to predict organizational performance and to guide organizations' investments in people. The new framework is based on a core set of HCM drivers that fall into five major categories: leadership practices, employee engagement, knowledge accessibility, workforce optimization, and organizational learning capacity. By employing rigorously designed surveys to score a company on the range of HCM practices across the five categories, it's possible to benchmark organizational HCM capabilities, identify HCM strengths and weaknesses, and link improvements or back-sliding in specific HCM practices with improvements or shortcomings in organizational performance. The process requires determining a "maturity" score for each practice, based on a scale of 1 (low) to 5 (high). Over time, evolving maturity scores from multiple surveys can reveal progress in each of the HCM practices and help a company decide where to focus improvement efforts that will have a direct impact on performance. The authors draw from their work with American Standard, South Carolina's Beaufort County School District, and a bevy of financial firms to show how improving HCM scores led to increased sales, safety, academic test scores, and stock returns. Bassi and McMurrer urge HR departments to move beyond the usual metrics and begin using HCM measurement tools to gauge how well people are managed and developed throughout the organization. In this new role, according to the authors, HR can take on strategic responsibility and ensure that superior human capital management becomes central to the organization's culture. 相似文献

Ventilator-associated pneumonia (VAP) accounts for the majority of nosocomial pneumonias, which may increase intensive care and prolonged hospital stays. Endotracheal tubes allowing continuous subglottic suctioning may reduce VAP; however, they are more expensive than standard endotracheal tubes not allowing continuous suctioning. he objective of this study was to measure the comparative costs associated with continuous subglottic suctioning endotracheal tubes (CSS-ETT) versus standard endotracheal tubes (S-ETT) among intubated patients and whether cost differential is offset by the occurrence of VAP in patients receiving either type of intubation. A retrospective chart review was conducted for 154 intubated adult patients (77 = S-ETT; 77 = CSS-ETT). The S-ETT group had one case of VAP; the CSS-ETT group had none. The mean total hospital charges were higher for the S-ETT group ($103,600; CSS-ETT= $88,500) (p = 0.3). Although the average number of intubation days and ICU days were greater for the CSS-ETT group, there were no cases of VAP compared to the S-ETT group. ased upon the one S-ETT VAP case and the VAP attributable costs, it is cost effective to use the CSS-ETT. 相似文献
