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

In this paper we use a large dataset to explore whether the liberalization of trade in services is beneficial for the international trade in goods. We find empirical evidence supporting this notion. We investigate which types of trade in services are more important for the international trade in goods and find that trade in transportation and communication services generate the largest impacts on trade in goods. We also investigate which types of trade in goods are likely to benefit from the liberalization of trade in services and find that, under the 2‐digit ISTC classification, all the categories are likely to exhibit a positive impact. 相似文献

A new framework is presented for the study of the existence and uniqueness of solutions to the Koopmans’ equation in the unbounded
case, that is based on the contraction mapping approach. In the bounded below case with bounded consumption streams, uniqueness
of the solution in the whole class of weak-star continuous utility functions is obtained. When the aggregator is unbounded
below and/or consumption streams are unbounded, existence of a weak-star continuous solution is shown, and a simple criterium
to check the sufficient conditions for existence is provided.

This paper presents a model of the interactions between natural resources and physical capital in the evolution of a tourist destination. The projected trajectory of the number of tourists approaches the classical lifecycle pattern. The post-stagnation phase is analyzed within the model, obtaining different patterns which depend on the impacts of physical capital on both demand and environmental degradation. The magnitudes of these impacts are determined by the type of tourism. An empirical application to the case of the tourist industry in the Canary Islands (Spain) is presented, showing that the model can represent the general characteristics of the post-stagnation phase of a tourist destination. 相似文献

This paper studies industry evolution driven by non strategic learning by doing and spillovers. We characterize a dynamic process of cost and output changes and its effect on welfare and industry profits. The paper gives conditions for shakeouts to occur and analyzes the key factors affecting these conditions. Since shakeouts could lead to a long-run social loss due to higher market concentration, there is a role for a government to play in limiting unnecessary shakeouts. The most effective way to do so is to enhance spillovers.JEL Classification:

Reinforcing the Link Between Contributions and Pensions: The Effect of the Population Aging 总被引:1,自引:0,他引:1
In this paper, we analyze a majority voting process on the earnings-related part of pension benefits in a Social Security system with flexible retirement. We show that the aging of the population may make it easier to implement one of the proposed reforms to achieve a delay in the average retirement age of workers, to reinforce the link between contributions and pensions. 相似文献

审计结果公告在发达国家是一种通行做法,近年来我国也颁布了相关的法律法规,但完整的审计结果公告制度尚未建立。审计结果公告制度的建立是一个系统工程,受政府信息公开程度、审计模式、审计规范体系等环境因素的影响和制约。文章从以上环境因素着手,分析比较了中美审计结果公告制度的异同,以期对我国审计结果公告制度建立和健全提供参考。 相似文献
