The interactions between natural and physical capitals in the tourist lifecycle model

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.     

Learning by doing,spillovers and shakeouts

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: L11, L13, O31Correspondence to: Michael TroegeWe would like to thank Hans Mewis, Christophe Moussu and an anonymous referee for valuable comments and suggestions.

Reinforcing the Link Between Contributions and Pensions: The Effect of the Population Aging

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.     

中美审计结果公告制度实施环境的比较及启示

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。     

A complete characterization of Pareto optimality for general OLG economies

In the context of general pure exchange OLG economies where agents can have heterogeneous longevities, we provide both sufficient and necessary conditions for Pareto optimality of competitive equilibria. For the case in which all agents live for the same number of periods, we find that these conditions are equivalent. We also find this equivalence when agents can have different lifetimes, but in this case we need to impose particular restrictions on relative equilibrium prices. Moreover, we show that without these conditions on prices the equivalence, and hence a full characterization, is not necessarily obtained.     

Cultural Inertia and Uniformity in Organizations

We analyze aspects of the structure of organizational culture.We show that old and culturally uniform organizations are proneto cultural inertia, that is, they are reluctant to adopt adifferent culture in response to a change in the environment.Cultural uniformity can be beneficial because the associatedinertia ex post protects and therefore ex ante encourages culture-specificinvestments by agents. We also explore the model's implicationsfor such issues as cultural uniformity within an organization,cultural heterogeneity across organizations, the destabilizingeffect of growth and mergers, and the conflicts arising in themanagement of culture.

我国制造业西移的成因和对策建议

实施西部大开发战略以来,西部地区的制造业出现了崛起的新迹象。但如果对西部大开发战略实施过程中的一些步骤、政策的设计或处理失当,尤其是对刚刚出现的制造业西移的现象关注不够,就会在实施中产生一些消极的影响,还会阻碍西部大开发战略的顺利实施。因此,加强对我国制造业西移现象的研究将成为一个迫切的任务。     

Strategic Environmental Standards, Wage Incomes and the Location of Polluting Firms

The purpose of this paper is tostudy how the choice of environmental standardsby governments is affected by the existence ofwage incomes when firms locations areendogenous. In developed countries labor isunionized, which allows positive wage incomesto arise. Thus, each government has incentivesto persuade firms to locate in its countrysince social welfare depends on suchincomes. But, as pollution damages theenvironment, each government will only try toattract polluting firms to thecountry, to obtain the wage incomes, whenthe valuation of environmental damage showsthat it is low.
