The paper distinguishes between the impact of the EMU on nominal wage flexibility and on equilibrium real wage and unemployment levels. A perceived need to increase nominal wage flexibility as a substitute for domestic monetary policy and a tendency to less real wage moderation in the EMU are likely to promote informal bargaining coordination and social pacts in the medium run. But such coordination is not likely to be sustainable in the long run, as it conflicts with other forces working in the direction of decentralization and deunionization. This could lead to more government intervention in wage setting during a transitional period. Although monetary unification will strengthen the incentives for higher-level transnational coordination of wage bargaining, such a development is improbable in view of the coordination costs involved. If transnational coordination develops, it is most likely to occur within multinational firms.  相似文献

This study describes a process in which a firm relies on an external consumer community for innovation. While it has been recognized that users may sometimes innovate, little is known about what commercial firms can do to motivate and capture such innovations and their related benefits. We contribute to strategy literature by suggesting that learning and innovation efforts from which a firm may benefit need not necessarily be located within the organization, but may well reside in the consumer environment. We also contribute to the existing theory on "user- driven innovation' by showing what firms purposively can do to generate consumer innovation efforts. An explorative case study shows that consumer innovation can be structured, motivated, and partly organized by a commercial firm that organizes the infrastructure for consumers' interactive learning in a public online domain.  相似文献

We document that analysts cater to short-term investors by issuing optimistic target prices. Catering dominates among analysts at brokers without an investment banking arm as they face lower reputational cost. The market does not see through the analyst catering activity and their forecasts lead to temporary stock overpricing that short-term institutional investors exploit to offload their holdings to retail traders. We also report evidence consistent with catering brokers being rewarded with more future trades channelled through them. Our study identifies a new source of conflicts of interest in analyst research originating from the ownership composition of a stock.  相似文献

This paper examines the role of the environment in Central and Eastern European states by pursuing the incompatibility between the economic development needed to maintain the democratic institutions already in place, and the crisis levels of environmental degradation in so many areas of Eastern and Central Europe. It is believed that costs of reversing environmental damages in these areas, and the implementation of sustainable development policies and technologies, are so great that the Eastern European states will be unable to meet them, which may lead to a further decline in the environmental quality in both CEE and the EU. This ability to impact the EU's environment could be the major factor in a decision by the EU to implement environmental taxes against these states. As a result, the possibility is raised that Russia may provide an alternative to the EU in the formation of a economically based bloc, with implications for trade, environment and security issues.  相似文献

An employer that sets up a defined benefit pension plan promises to periodically pay a certain sum to each participant starting at some future date and continuing until death. Although both the future beneficiary and the employer can be asked to finance the plan throughout the beneficiary's career, any shortcoming of funds in the future is often the employer's responsibility. It is therefore essential for the employer to be able to predict with a high degree of confidence the total amount that will be required to cover its future pension obligations. Applying mortality forecasting models to the case of the Royal Canadian Mounted Police pension plan, we illustrate the importance of mortality forecasting to value a pension fund's actuarial liabilities. As future survival rates are uncertain, pensioners may live longer than expected. We find that such longevity risk represents approximately 2.8 percent of the total liability ascribable to retired pensioners (as measured by the relative value at risk at the 95th percentile) and 2.5 percent of the total liabilities ascribable to current regular contributors. Longevity risk compounds the model risk associated with not knowing what is the true mortality model, and we estimate that model risk represents approximately 3.2 percent of total liabilities. The compounded longevity risk therefore represents almost 6 percent of the pension plan's total liabilities.  相似文献

This paper develops the fundamental aspects of the theory of martingale pricing of derivative securites in a setting where the cumulative gains processes are Itô processes while the cumulative dividend processes of both the underliers and the derivative securities are general enough to cover all cases encountered in practical applications. A key ingredient is a general formula for how to change the unit of account of a cumulative dividend process. The formula is inconsistent with parts of the earlier literature. It obeys a unit-invariance rule for trading strategies, satisfies a consistency property when the unit is changed twice in a row, gives the correct results in well-known and uncontroversial special cases, and fits perfectly into a generalization of the martingale valuation theory. Using that generalized theory, we show that the value of a dividend process equals the value of a claim to the nominal amount of dividends yet to be accumulated plus the value of a flow of interest on the cumulative dividends at each point in time.  相似文献
