Research summary : Research demonstrates that foreign firms from institutionally distant countries imitate the practices of domestic firms (i.e., adopt an isomorphism strategy). The conjecture has been that pursuing such a strategy can help foreign firms counteract the deleterious performance consequences associated with institutional distance; yet there is scant evidence of such. This study treats isomorphism as an endogenously selected strategy influenced by institutional distance to examine its performance consequences. Using a dataset of 80 foreign banks from 25 countries operating in the United States, we find that foreign firms from institutionally distant home countries benefit initially from selecting an isomorphism strategy. However, the benefits diminish with experience. Managerial summary : Multinational companies experience great difficulty in managing institutional distance, and research suggests that one way to overcome distance‐related constraints is to imitate the strategies of local companies. Unfortunately, we do not know enough about the performance‐related consequences of engaging in such imitative behavior. This study examines whether imitating local firms improves performance for multinational companies from institutionally distant markets. We find that imitation improves a firm's performance at first; however, with experience those same strategies result in performance decrements. Managers of multinationals should therefore be careful not to get locked into imitative strategies that provide performance benefits upon entry, but that fail to provide benefits over time.

Research shows that, under certain circumstances, people using GSS can be substantially more productive than people who do not. However GSS has been slow to transition into the workplace. This paper argues that the Technology Transition Model (TTM) may be a useful way to explain this seeming paradox. The paper presents a case study of GSS transition in two organizations – one where a self-sustaining and growing community of users emerged, and one where it did not. Following TTM, it explores the frequency with which users perceived cognitive, economic, affective, political, social, and physical value from using the system. Comparison of the cases reveals differences in perceptions of value along several of these dimensions that are consistent with TTM. The findings suggest the model may be a useful way to explain the transition of collaboration technology, but more research will be required to test the model more rigorously.  相似文献

This paper presents an economic interpretation of the optimal “stopping” of perpetual project opportunities under both certainty and uncertainty. Prior to stopping, the expected rate of return from delay exceeds the rate of interest. The expected rate of return from delay is the sum of the expected rate of change in project value and the expected rate of change in the option premium associated with waiting. At stopping the expected rate of return from delay has fallen to the rate of interest. Viewing stopping in this way unifies the theoretical and practical insights of the theory of stopping under certainty and uncertainty.  相似文献

Abstract

In the present study two recreational activities, deer hunting and goose hunting, both similar in form, are compared. The study shows that the activity with the fewest perceived substitutes, deer hunting, also showed higher mean ratings on items measuring the importance of various elements of the experience, such as the process of participation, the goal of the activity, and the social interaction that accompanies the activity by the participants. Deer hunters also reported greater participation in the activity by peers and were more likely to be introduced to the activity by a family member. It is argued that these differences in the importance of the elements of the experiences influence the perceived substitutability of a recreational activity.  相似文献

Although the Industrial Relations Act marks the most significant break with the traditional “abstentionist” role of the law in British labour relations, it is true to say that during the last ten years the development of public policy has entailed a growing involvement of lawyers and the law in the world of work. As Professor Kahn-Freund has written:  相似文献

This paper integrates the theory of demand for publicly provided goods in a democracy with the theory of bureaucratic supply in order to develop a model of benefit share and tax share discrimination by a monopoly bureau. The demand side of the political market is based on a utility maximizing model of voter behavior with voters' demands aggregated through a majority voting process. The supply side of the political market is based on a budget maximizing model of bureaucratic behavior. The bureau is assumed to possess monopoly power as a result of either its control over benefit shares or tax shares and, hence, implicit tax prices or its control over budget proposals placed on the agenda. Different degrees of discrimination are examined and in each case the equilibrium of the model yields a total budget for the bureau as well as distributions of benefit shares or tax shares across voters.  相似文献

The firm dynamics literature has stressed productivity, size, and age effects in firm duration. Understanding the implications of financial state has largely been unexplored because of the lack of quality data on private entrant firms. This paper investigates the role of start‐up financial conditions (debt‐to‐asset ratio) on the duration of entrant manufacturing firms using a unique administrative firm‐level database called T2LEAP. The debt‐to‐asset ratio has an economically and statistically significant effect on firm hazard after controlling for usual covariates and unobserved heterogeneity. Further, a non‐monotonic relationship between firm hazard and leverage appears. Firm hazard varies positively with leverage for firms in the top two leverage quintiles, whereas hazard rates fall with leverage in the lower quintiles.

This paper estimates the revenue potential of a financial transaction tax (FTT) for US financial markets. We focus on analyzing the revenue potential of the Inclusive Prosperity Act that was introduced in the US House of Representatives in 2012 and the US Senate in 2015. The tax rates stipulated in this Act include 0.5% (50 basis points (bps)) for all stock transactions, 0.1% (10 bps) for all bond transactions and 0.005% (0.5 bps) on the notional value of all derivative trades. We examine three sets of evidence to generate potential revenue estimates: 1) the levels of transaction costs in US financial markets over time and within the range of financial market segments; 2) the extent of trading elasticities under various trading conditions; and 3) the current level of trading activity in US financial markets. Based on this evidence, we conclude that a US FTT operating at the tax rates stated above would generate about $220 billion per year, equal to about 1.2% of the current US GDP.  相似文献
