Abstract This paper deals with the issue of banking and borrowing in the context of the European Union Emissions Trading Scheme (EU ETS) by attempting to provide a policy‐oriented unifying theoretical framework. After describing the main features of the EU ETS, the core part of the paper consists of variations of an intertemporal continuous time optimization model. Additional elements include flexibility measures currently discussed and proposed in other emissions trading systems (USA, Australia), which include the use of safety valves, minimum price auctioning or offsets from domestic or international projects. 相似文献

Once a patent is found to have been infringed the law generally entitles the patentholder to monetary losses suffered as the result of the illegal conduct. It is shown here that there are important differences between the losses awarded under U.S. case law and those that economic models of competition indicate would allow patentholders to just capture the social value of their innovations and, with that, provide private incentives for efficient levels of innovation. The prevailing case law generally overestimates the harm, providing an incentive for the patentholder to opportunistically claim infringement. In the end this increases the reward to innovation and encourages overinvestment. The record of the widely read State Industries vs. Mor-Flo Manufacturing Co. (883 F.2d 1573, Fed. Cir. 1989, cert. denied, 493 U.S. 1022, 1990) provides a case study. 相似文献

Media effects on image: The Case of Tibet 总被引:7,自引:1,他引:7
Julien 《Annals of Tourism Research》2005,32(4):1039-1055
Using media effects research as a theoretical framework, this paper examines empirically the impact of media representations—such as movies, guidebooks, and magazines—on destination image. Past research has focused on either representations or image, but rarely on both. Based on a systematic comparison of the former with the latter, it is argued that the impact of media representations on image falls between a strong and negotiated influence. The analysis is based on data collected from tourists in Lhasa, Tibet. The paper documents tourism issues in a renowned but little studied destination. 相似文献

We present a competing-auction theory of the labor market, where job candidates auction their labor services to employers. An equilibrium matching function emerges which has many of the features commonly assumed, including constant returns to scale in large economies. The auction mechanism also generates equilibrium wage dispersion among homogeneous workers and constrained-efficient entry of vacancies in large economies. In a dynamic version of the model, we generate implied numerical values for equilibrium unemployment and wage dispersion. The theory makes the novel prediction that wage dispersion is a decreasing function of the discount factor and labor market tightness.

The notion of a natural real rate of interest, due to Wicksell (Interest and prices. Macmillan, London Translation of 1898
edition, 1936), is widely used in current central bank research. The idea is that there exists a level at which the real interest
rate would be compatible with output at its potential level and stationary inflation. Such a concept is of primary concern
for monetary policy because it provides a benchmark for the monetary policy stance. This paper applies the method suggested
by Laubach and Williams (Rev Econ Stat 85(4):1063–1070, 2003) to jointly estimate the natural real interest rate and the output
gap in the euro area using data from 1960 onwards. Our results suggest that the natural real rate of interest has declined
gradually over the past 40 years. They also indicate that monetary policy in the euro area was on average stimulative during
the 1960s and the 1970s, while it contributed to dampen the output gap and inflation in the 1980s and 1990s.

We consider a signaling model where the sender?s continuation value after signaling depends on his type, for instance because the receiver is able to update his posterior belief. As a leading example, we introduce Bayesian learning in a variety of environments ranging from simple two-period to continuous-time models with stochastic production. Signaling equilibria present two major departures from those obtained in models without learning. First, new mixed-strategy equilibria involving multiple pooling are possible. Second, pooling equilibria can survive the Intuitive Criterion when learning is efficient enough. 相似文献

Existing empirical models fail to explain the surge in the accumulation of foreign exchange reserves by emerging countries during the last decade. This paper provides an estimate of the demand for international reserves on a panel of emerging countries using a time‐varying panel smooth transition regression (TV‐PSTR) model to relax the assumption of coefficient stability in the relationship. Evidence is dound that the parameters are not constant. In addition, it is observed that the coefficients remained relatively stable until 2000 and then increased gradually and strongly thereafter. The specification provided here accounts for an acceleration that linear specifications fail to explain. Finally, it is found that mercantilist motives are the major driver of this acceleration. 相似文献

This paper investigates whether the international globalization of financial markets allows for significant cross-country risk-sharing at the business cycle frequency. We find that cross-country risk-sharing is still limited and this is unlikely to be the result of financial frictions that limit state-contingent contracts. Part of the limited international risk sharing could be the consequence of frictions that de-facto reduce the short-term mobility of financial capital. But even with these frictions we find significant divergence between model predictions and the data. 相似文献
