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

Abstract. Researchers have used stylized facts on asset prices and trading volume in stock markets (in particular, the mean reversion of asset returns and the correlations between trading volume, price changes and price levels) to support theories where agents are not rational expected utility maximizers. This paper shows that this empirical evidence is in fact consistent with a standard infinite horizon – perfect information – expected utility economy where some agents face leverage constraints similar to those found in todays financial markets. In addition, and in sharp contrast to the theories above, we explain some qualitative differences that are observed in the price-volume relation on stock and on futures markets. We consider a continuous-time economy where agents maximize the integral of their discounted utility from consumption under both budget and leverage constraints. Building on the work by Vila and Zariphopoulou (1997), we find a closed form solution, up to a negative constant, for the equilibrium prices and demands in the region of the state space where the constraint is non-binding. We show that, at the equilibrium, stock holdings volatility as well as its ratio to stock price volatility are increasing functions of the stock price and interpret this finding in terms of the price-volume relation.

The present paper considers some new models for the analysis of multidimensional contigency tables. Although the theoretical background used here appeared already in Haberman (1974), prescribed conditional interaction (PCIN) models were introduced by Rudas (1987) and their mathematical properties were worked out by Leimer and Rudas (1988). These models are defined by prescribing the values of certain conditional interactions in the contingency table. Conditional interaction is defined here as the logarithm of an appropriately defined conditional odds ratio. This conditional odds ratio is a conditional version of a generalization of the well known odds ratio of a 2×2 table and that of the three factor interaction term of a 2×2×2 table and applies to any number of dimensions and any number of categories of the variables. The well known log-linear (LL) models are special PCIN models. Estimated frequencies under PCIN models and tests of fit can be computed using existing statistical software (e.g. BMDP). The paper describes the class of PCIN models and compares it to the class of association models of Goodman (1981). As LL models are widely used in the analysis of social mobility tables, application of more general PCIN models is illustrated.  相似文献

A bstract . The actions of government fall into two types: taxes (the taking of property ) and expenditures (the awarding of gifts ). Politicians profit as long as the value of resources raised from taxation exceeds the cost of expenditures. From their point of view, fiscal efficiency consists in maximizing the support obtained by spending and minimizing the opposition generated by taxing. This is accomplished by spending on well-organized groups and taxing the uninformed public. This results in the "iron law of political redistribution" in which income and wealth are transferred from the latter to the former. In a hierarchical State , it is usually profitable for those at the top to centralize control over taxing and spending, if for no other reason than to make it difficult for politicians at lower levels to compete against them. This gives rise to the "law of hierarchical centralization "—in a hierarchical State, power becomes centralized over time. The greater the power of government, the faster this process takes place. In order to avoid this problem, one could design constitutions which are non-hierarchical in nature, in which each unit of government is completely autonomous from the others, as firms are in a free market.  相似文献

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.  相似文献

In this paper we examine a number of issues that arise in investigating labor force dynamics using the Spanish Labor Force Survey (EPA). These issues are by no means specific to the Spanish case and apply to most European-style labor force surveys. Our main conclusions may be summarized as follows. First, survey nonresponse cannot be neglected. Second, the EPA tends to underestimate employment and participation of high-educated young people, and to overestimate those of the low-educated elderly. Finally, we find little evidence that attrition causes important selection biases in estimating quarterly transition probabilities.  相似文献

The theme is Arrow's requirement in his theorem of 1951 on methods for group choice, that the choice be independent of irrelevant alternatives. The attention is drawn to (1) his own explanation of this requirement in 1972, which is a quite different understanding than has been discussed in the voluminous literature on the theorem, (2) that Arrow, in fact, in 1985 showed an understanding for how irrelevant alternatives might in a meaningful way influence the group choice, (3) that admittedly the border-line between irrelevant and relevant alternatives in Arrow's original statement is arbitrary, and (4) that Arrow, if he had observed the final thought in the origin of the group theory by Borda, which he admittedly did not, might have realized that Borda's method stringently estimates the relevance of each alternative for the result.The author expresses his surprise that a theoretical conclusion based on an arbitrary fundament has been admired so long.  相似文献

The impressive and spontaneous build-up of the private small and medium-sized enterprises (SMEs) in the Czech Republic in 1990–93 coincided with the similarly dramatic changes in the public administration and in the whole environment for decision-making. The resulting problems of SMEs in the Czech Republic seem to be common to all economies in transition. A lot of the problems are caused by the macroeconomic policy for which this sector is not the most important part of the national economy. The paper shows some conflicts between macroeconomic anti-inflationary (monetary and fiscal) policies, and interests of small businesses. The authors stress the importance of SMEs during the period of transition. Informal aspects of the functioning of small firms are discussed, especially their relation with banks and public administration. The paper offers some empirical evidence and available statistics on SMEs developments during 1990–94 focusing particularly on manufacturing.  相似文献

This paper analyses the influence exerted by compulsory mechanisms and cognitive and social factors on the adoption and implementation of double-entry bookkeeping. The study focuses on a small, commercial and family owned company located in Spain in the period 1829-1852. As our main conclusion we suggest that the adoption of double-entry bookkeeping in 1851 was influenced more by the managers' self-perception as traders, and the belief (internal and environmental) that the company must employ an accounting method appropriate to its new commercial status, than by State pressures derived from the enactment of a new accounting regulation in 1829.  相似文献
