We study the effects of the Internet on regional price differences. Comparing two Dutch regions, we find that before the rise of the Internet, price differences of used cars between those regions amounted to some 11–15%, controlling for mileage, age, fuel type and engine volume. These price differences have completely disappeared after the rise of the Internet, in particular a website that allows consumers to make detailed comparisons between almost all used cars for sale in the Netherlands.  相似文献

 Many government and private programs provide incentives for non-industrial private forest (NIPF) owners. Due to the complexity of this web of programs, the incentives of the programs are unclear. We focus on four specific programs that represent different rule structures—a federal cost-share program, a state tax incentive program, a nationwide private stewardship program, and a local private conservation organization. We perform institutional analysis of the formal and informal rules of the programs based on literature review, discussions with officers, and formal guidelines of the programs. We classify different types of rule structures, and explain them in relation to goals and organizational structures of the programs.  相似文献

We explore the conditions under which the “first‐order approach” (FO approach) can be used to characterize profit maximizing contracts in dynamic principal–agent models. The FO approach works when the resulting FO‐optimal contract satisfies a particularly strong form of monotonicity in types, a condition that is satisfied in most of the solved examples studied in the literature. The main result of our paper is to show that except for nongeneric choices of the stochastic process governing the types' evolution, monotonicity and, more generally, incentive compatibility are necessarily violated by the FO‐optimal contract if the frequency of interactions is sufficiently high (or, equivalently, if the discount factor, time horizon, and persistence in types are sufficiently large). This suggests that the applicability of the FO approach is problematic in environments in which expected continuation values are important relative to per period payoffs. We also present conditions under which a class of incentive compatible contracts that can be easily characterized is approximately optimal.  相似文献

Defending Gibrat’s Law as a long-run regularity   总被引:1,自引:0,他引:1  
According to Gibrat’s Law of Proportionate Effect, the growth rate of a given firm is independent of its size at the beginning of the period examined. While earlier studies tended to confirm the Law, more recent research generally rejects it. This article reconciles these two streams of literature, taking into account the role of market selection and learning in reshaping a given population of firms through time. Consistently with previous studies, we find that Gibrat’s Law has to be rejected ex ante, since smaller firms tend to grow faster than their larger counterparts. However, a significant convergence toward Gibrat-like behavior can be detected ex post. This finding is an indication that market selection “cleans” the original population of firms, so that the resulting industrial “core” does not depart from a Gibrat-like pattern of growth. From a theoretical point of view, this result is consistent with those models based on passive and active learning, and can be seen as a defense of the validity of the Law in the long-run.

This work focuses on corporate social responsibility (CSR) disclosure practices of multinational corporations. Based on a longitudinal study of CSR reports of companies operating in the automotive industry, the paper offers a detailed study of how disclosure practices are changing and which principles and approaches influence and drive the development of such disclosure. Based on a four-year report-based study, the findings enable us to identify three main trends in the CSR disclosure strategy of automotive firms. First, in line with the mainstream CSR literature, the present study confirms the trend towards the increasing environmental and social accountability. Second, it adds evidence to the emerging debate regarding the harmonization and standardization of reporting and discusses this aspect by mentioning the standards as exerting some normative pressures within the sector. Finally, it provides evidence on specific links emerging between issues and actors. The implications of this evidence contribute to opening up the debate on CSR disclosure to the possibility of combining the institutional lens with a strategic approach that captures the materiality considerations of CSR disclosure.  相似文献

Summary This paper analyzes empirically the relationship between pay and performance. Economic and psychological theories predict that the design and implementation of a performance measurement and compensation system affect the motivation of employees. Our survey results demonstrate a positive relationship between the perceived characteristics of the complete compensation system and extrinsic motivation. Intrinsic motivation is not affected by the design of monetary compensation, but by promotion opportunities. The compensation system also significantly affects work satisfaction and turnover intent. Our results have both managerial as well as policy implications. We would like to thank the organization and the participants of the 2002 conference of the Performance Measurement Association in Boston for helpful discussions and also seminar participants of the Dutch Labor Market Conference. We are grateful for the comments provided by Bruno S. Frey. The paper has also significantly benefited from the suggestions and comments of two anonymous referees.  相似文献

Empirical research in international trade has shown that exporting firms display higher productivity than their non-exporting competitors. This paper focuses on the relation between export and profitability. Our evidence on Italian exporting firms shows that exporting activity is not systematically associated to higher firm’s profitability. This is shown both by means of non-parametric methods and, with an approach that is more standard within the empirical trade literature, by regression techniques that try to identify an “export premium”.  相似文献

Innovation diffusion theory suggests that consumers differ concerning the number of contacts they have and the degree and the direction to which social influences determine their choice to adopt. To test the impacts of these factors on innovation diffusion, in particular the occurrence of hits and flops, a new agent‐based model for innovation diffusion is introduced. This model departs from existing percolation models by using more realistic agents (both individual preferences and social influence) and more realistic networks (scale free with cost constraints). Furthermore, it allows consumers to weight the links they have, and it allows links to be directional. In this way this agent‐based model tests the effect of VIPs who can have a relatively large impact on many consumers. Results indicate that markets with high social influence are more uncertain concerning the final success of the innovation and that it is more difficult for the innovation to take off. As consumers affect each other to adopt or not at the beginning of the diffusion, the new product has more difficulties to reach the critical mass that is necessary for the product to take off. In addition, results of the simulation experiments show under which conditions highly connected agents (VIPs) determine the final diffusion of the innovation. Although hubs are present in almost any network of consumers, their roles and their effects in different markets can be very different. Using a scale‐free network with a cut‐off parameter for the maximum number of connections a hub can have, the simulation results show that when hubs have limits to the maximum number of connections the innovation diffusion is severely hampered, and it becomes much more uncertain. However, it is found that the effect of VIPs on the diffusion curve is often overestimated. In fact when the influence of VIPs on the decision making of the consumers is strengthened compared with the influence of normal friends, the diffusion of the innovation is not substantially facilitated. It can be concluded that the importance of VIPs resides in their capacity to inform many consumers and not in a stronger persuasive power.  相似文献

Most tourism social impact studies emphasise tangible social impacts such as economic improvement. In developing countries such as South Africa, a small percentage of tangible benefits filter down to community level. This creates a problem as various studies revealed the importance of community support for the sustainability of the tourism industry. Therefore it was important to explore the role of both the tangible and the intangible social impacts of tourism. Communities with established tourism industries (Clarens, Soweto and Jeffreys Bay) formed part of the quantitative research. Through exploratory factor analyses, 31 social impact statements could be categorised into four tangible and two intangible impacts. The tangible factor Economic improvement obtained a low rating, meaning that it was not directly experienced by residents, while the intangible factor Community pride and upliftment obtained the highest rating among all factors. This, together with the fact that community members continue their support for the tourism industry, is a novel find, indicating the significant role of intangible social impacts in fostering community support. This finding shows the importance of incorporating intangible social impacts into tourism planning in developing countries. Contributions are made towards social impact research methodology and literature.  相似文献
