The last several years were very favourable to the development of the Russian economy. While this has partly been the consequence
of favourable conditions on the international markets for raw materials, the economic policy of President Vladimir Putin,
including the tax reforms initiated at the end of the 1990s, also played a major role. Our authors examine in detail the effects
of the tax reforms to date and point out the room for further improvements under Putin’s successor, Medvedev. 相似文献

This study examines the composition of customer order .flow and the execution quality for different types of customer orders in six futures pits of the Chicago Mercantile Exchange (CME). It is shown that off‐exchange customers frequently provide liquidity to other traders by submitting limit orders. The determinants of customers' choice between limit and market orders are examined, and it is found that higher bid—ask spreads increase the limit‐order submission frequency, and increased price volatility makes limit‐order submission less likely. Effective spreads, trading revenues, and turnaround times for customer liquidity‐demanding and limit orders are also documented. Consistent with evidence from equity markets, the results show that limit‐order traders receive better executions than traders using liquidity‐demanding orders, but incur adverse selection costs. © 2005 Wiley Periodicals, Inc.

Dynamic changes in the business environment are significantly impacting supply chain logistics, resulting in unprecedented personnel demands. Organizational theorists suggest that personnel management is associated with better performance. However, relatively little is known about effective human resource practices within the logistics industry. The learning organization concept offers logistics organizations a theoretical rationale for promoting learning environments to better leverage employees' knowledge, skills, and abilities and improve performance. This research examines logistics managers' perceptions of individual level learning behavior within their organizations and its relationship to firm performance. 相似文献

Standard economic models of criminal behavior analyze the criminal's decision in a partial equilibrium context. The standard model does not recognize that the probability of being punished is a function of the total amount of crime that occurs. As the total amount of crime increases, police resources become strained, courts become congested, and prisons become overcrowded. As a result, proportionately fewer criminals are apprehended, convicted, and imprisoned. The feedback effects from one criminal's decision to participate in crime to another criminal's decision can be highly significant. In one parameterization of the model developed here, the individual commits twice as many crimes for a given parameter shift than is implied by the standard model. The model also sheds light on other areas where criminal actions are interdependent such as riots, crime waves, and revolutions. 相似文献

In a static setting, willingness to pay for an environmental improvement is equal to compensating variation. In a dynamic
setting, however, willingness to pay may also contain a commitment cost. In this paper we incorporate the dynamic nature of
the value formation process into a stated preference study designed to test whether there is an important dynamic component
(commitment cost) in stated preference values. The results clearly indicate that stated preference values can contain commitment
costs and that these can be quite large: respondents offered the opportunity to delay their purchasing decisions until more
information became available were willing to pay significantly less for improved water quality than those facing a now-or-never
decision. These results have important consequences for the design and interpretation of stated preference data. 相似文献

This paper studies the use of product development management models. Through an interpretive research approach based on in-depth interviews with 22 middle managers in two product development organizations, five ways of conceiving projects, project management and the role of models are identified – administrative, organizing, sense giving, team building and engineering – all representing different perspectives on – and ways of using models. The findings question essentialist views of models, common in the literature, as either normative guides for action or symbolic tools decoupled from action. Instead, the study indicates a large variety in the use of models mediated by the user's conception of the situation and the model. The study highlights the communicative role of models as boundary objects, enabling coordination of and communication about different conceptions of the development task. Rather than contributing to behavioral standardization (an implicit assumption that underlies most formal models), this study suggests that models support cognitive standardization by providing a common set of concepts and a framework that may be drawn upon in making sense of complex product development projects. 相似文献

All financial transactions in the original Walrasian economy, as written in the édition définitive of the éléments, occur
in the markets for short-term money services (the short-term bond market) and commodity E (the equity market). However, introduction
of the long-term bond and the deposit markets requires only minor surgery to the original and they are now supplied, inspiring
the name mature Walrasian economy. Transactions in numeraire then entail all institutions of the banking system and provide
completely for money and credit. Into this economy the condition of inconvertibility, a discretionary numeraire with reserve
requirements, and a central bank are introduced and clarified. Finally, multiple monetary subsystems in the same global economy
are recognized and reconciled, thus establishing a global economy with a single numeraire commodity. 相似文献

The amended Food, Drug and Cosmetics Act requires efficacy certification for a drug's initial uses (“on‐label”), but does not require certification before physicians may prescribe the drug for subsequent uses (“off‐label”). Does it make sense to require FDA efficacy certification for new drugs but not for new uses of old drugs? Using a sequential online survey, we carried on a “virtual conversation” with some 500 physicians. The survey asked whether efficacy requirements should be imposed on off‐label uses; almost all physicians said no. It asked whether the efficacy requirements for initial uses should be dropped, and most physicians said no. We then asked respondents whether opposing efficacy requirements in one case but not the other involved an inconsistency. In response, we received hundreds of written commentaries. We organize and discuss these commentaries with an eye to understanding how the medical market certifies off‐label drug uses and how this compares to FDA certification. Does off‐label medicine use suggest that efficacy requirements should be placed on new uses of old drugs? Does it suggest that efficacy requirements on new drugs should be lifted? We explore these questions, and ask whether the response of many of the doctors exhibits the familiar behavior bias toward the status quo. 相似文献

Short‐run own‐price response elasticities are estimated from two samples of panel data for specialist dairy farms in the Northwest and Southwest of England. Although these farms are subject to milk marketing quotas, the free tradability of quotas enables them individually to adjust the output quite rapidly. Model specifications have been chosen to test the ability of panel data to directly reveal behavioral responses without the imposition of theoretical restrictions. Significantly, the two independent samples generate quite similar results, especially in terms of supply response measures. Stable and promising estimates are obtained with simultaneous models giving higher elasticities than single equation models. 相似文献
