We study the optimal monetary policy in a two-country open-economy model under two monetary arrangements: (a) multiple currencies controlled by independent policy makers; (b) common currencies with a centralized policy maker.
Our findings suggest that: (i) monetary policy competition leads to higher long-term inflation and interest rates with large welfare losses; (ii) the inflation bias and the consequent losses are larger when countries are unable to commit to future policies; (iii) the welfare losses from higher long-term inflation dominates the welfare costs of losing the ability to react optimally to shocks. 相似文献

We analyze optimal patent design when innovators can rely on secrecy to protect their innovations. Secrecy has no fixed term but does not preclude accidental disclosure nor independent creation by other inventors. We derive the optimal scope of the rights conferred to such second inventors, showing that if the patent life is set optimally, second inventors should be allowed to patent and to exclude first inventors who have relied on secrecy. We then identify conditions under which it is socially desirable to increase patent life as much as is necessary to induce first inventors to patent. The circumstances in which it is preferable that they rely on secrecy seem rather limited . 相似文献

Reinsurance allows insurance companies to diversify their risks. However, from this original role, insurance companies have developed various reinsurance strategies in order to expand their market share. From the last decades of the nineteenth century to the 1940s, Spanish insurance companies used reinsurance in a largely unregulated context. This article analyses the reinsurance practices and their adaptation to the singularities of the Spanish market, namely: the difficulties for the consolidation of a core of pure reinsurers; the management of reinsurance in the internationalisation process; and the use of reinsurance by mutual societies to overcome their lack of equity capital. 相似文献

In this paper, I study a model in which shocks to asset prices affect the real sector of the economy through a credit channel. As financial markets become internationally integrated, the economy becomes less vulnerable to domestic asset‐price shocks, but more vulnerable to foreign asset‐price shocks. To the extent that monetary policy stabilization is feasible and desirable, the globalization of financial markets shifts the focus of monetary policy from domestic asset prices to worldwide asset prices. 相似文献

Classical put–call symmetry relates the price of puts and calls under a suitable dual market transform. One well‐known application is the semistatic hedging of path‐dependent barrier options with European options. This, however, in its classical form requires the price process to observe rather stringent and unrealistic symmetry properties. In this paper, we develop a general self‐duality theorem to develop valuation schemes for barrier options in stochastic volatility models with correlation. 相似文献

This article examines the merit of the test of the average consumer as a basis for judicial and regulatory action. In the
first part, we describe the origin of the test, its application in the Unfair Commercial Practices Directive and its possible
developments. In the second part, we discuss the theoretical grounds of the average consumer test (i.e., information and rationality),
drawing upon the studies of cognitive psychology and behavioural economics concerning consumers’ behaviour. The result of
our analysis is that we call into serious question the practical workability of the test of the average consumer, which requires
consumers an overly demanding standard of rationality and information without dedicating much attention to the real functioning
of consumer behaviour. The average consumer may be described as an interesting, anti-paternalistic and, to some extent, useful
notion. It is, however, an overly simplistic concept with little correspondence with the real world of individual consumer
behaviour and should be reinterpreted more flexibly, or even abandoned to mirror consumer behaviour more effectively.

This paper examines empirically the relationship between electricity spot and futures prices, by analysing a decade of data for a set of short term-to-maturity futures contracts traded in the Nordic Power Exchange. It is found that, on average, there are significant positive risk premiums in short-term electricity futures prices. The significance and size of the premiums, however, varies seasonally over the year; whereas it is greatest during winter, it is zero in summer. It is also found that time-varying risk premiums are significantly related to unexpectedly low reservoir levels. Furthermore, before the unprecedented supply-shock that hit the market around the end of year 2002, the risk premiums were related to the variance and the skewness of future spot prices. 相似文献

This article presents an intergenerational self‐selection model of migration and education that is capable of explaining the evolution of earnings and education across three generations of immigrants. By structurally estimating the model, it is possible to quantify the sacrifices made by the first generation of Mexican immigrants for the benefits of future generations. In particular, the estimation results suggest that there is a significant one time loss of human capital of immigrants upon migration, that migrants are positively selected from the ability distribution, and that they transmit substantial human capital to their children. Finally, the model is used to evaluate the effects of social policies designed to reduce the “brain drain” from Mexico to the United States. 相似文献

We consider the credit risk model of Collin-Dufresne and Goldstein (2001). According to this model, the price of a defaultable bond can be efficiently computed using a variational formulation that consists of an integral relation and a Volterra integral equation. In Collin-Dufresne and Goldstein (2001) this integral equation is justified by a probabilistic intuition, but is not proven formally. In this paper we analytically derive the variational formulation used in Collin-Dufresne and Goldstein (2001). This analysis allows to give a correct characterization of the solution of the integral equation. Furthermore the approach proposed in this paper could also be employed for other models of credit risk. 相似文献
