Summary. We analyze an infinite horizon model where a seller who owns an indivisible unit of a good for sale has incomplete information
about the state of the world that determines not only the demand she faces but also her own valuation for the good. Over time,
she randomly meets potential buyers who may have incentives to manipulate her learning process strategically. We show that
i) the seller's incentives to post a high price and to experiment are not necessarily monotonic in the information conveyed
by a buyer's rejection; and ii) as the discount factors tend to one, there are equilibria where the seller always ends up
selling the good at an ex-post individually rational price.

Altruism is a type of non-use value which can have different definitions depending on the type of goods entering the utility function of the altruists and their expectations about the contributions of others. The purpose of this paper is to measure the trade-offs between different types of altruist values originating from social and environmental policies. Environmental policies are concerned with reducing health effects from a power plant while social policies involve both the attainment of public facilities for education and leisure and an increase in the income of the affected population. The empirical application utilizes a choice experiment technique which allows for valuation of multiple goods. Health effects are decomposed into the values of the risk of becoming ill, the duration of the episodes and the limitations imposed by illness. Altruist values are elicited from a population that is not affected by pollution. Results show that altruism is significant for policies directed to reducing health effects and improving the income level of the affected population, whereas there is egoism for a policy aimed at improving public facilities in the polluted suburb. The value of altruism is significantly influenced by the expectations of net benefits to be received by the affected population. 相似文献

Abstract. The aim of this paper is to estimate the effect of fertility on the decision of labour force participation of married females
in Spain, allowing for the existence of unobserved characteristics that affect both fertility and participation. We use a
pooling of five waves of the European Household Panel for Spain (1994–1998). Results indicate that not taking into account
the unobserved characteristics that affect both variables imposes on average a strong downward bias on the true effect of
fertility on participation. This bias is especially strong for highly educated females.

Long memory in volatilities of German stock returns 总被引:3,自引:0,他引:3
We show that there is strong evidence of long-range dependence in the volatilities of several German stock returns. This will be done by applying a method using the difference of the classical log-periodogram regression estimator for the memory parameter and of the tapered periodogram based estimator. Both estimators give similar values for the memory parameter for each series and this indicates long memory. To support our findings we apply also a methodology using the sample variance and a wavelet based estimator to the data. Also these two methods show clear evidence of long-range dependence in the volatilities of German stock returns.First version received: December 2001/Final version received: March 2003The computational assistance of Eleni Mitropoulou and Björn Stollenwerck as well as the helpful comments of two unknown referees are gratefully acknowledged.

In this paper the stability of an International Environmental Agreement (IEA) among N identical countries that emit a pollutant are studied using a two-stage game. In the first stage each country decides noncooperatively whether or not to join an IEA, and in the second stage signatories jointly against nonsignatories determine their emissions in a dynamic setting defined in continuous time. A numerical simulation shows that a bilateral coalition is the unique self-enforcing IEA independently of the gains coming from cooperation and the kind of strategies played by the agents (open-loop or feedback strategies). We have also studied the effects of a minimum participation clause finding that for this case a self-enforcing IEA just consists of the number of countries established in the clause.JEL Classification:

Seven computerprograms for non-linear regression or curve fitting problems are compared. The comparison of the programs, running in different computing centra, is restricted to the fit performance. Six model functions are fitted according to the least squares criterion to data series, arising from practical work. The special least squares minimization programs turned out to be better suited for these problems than general optimizing programs. 相似文献

The aim of this paper is to analyze the economic and social cohesion in the European Union. There are different factors to
explain the convergence process and besides, empirical findings are not conclusive. To the European Union, GDP per head interregional
differences have decreased for certain periods but it has remained unchanged or even increased for others periods. The second
report on the economic and social cohesion indicates that some decades are necessary to eliminate regional differences. These
differences in regional GDP are mainly explained by differences in their productive structures, degree of innovate activity,
communications structures, which depend on the relative level of transport infrastructures, and manpower qualifications. This
analysis allows us to obtain some conclusions to the economic policies and the social cohesion.

This article investigates the role of taxation when public goods are privately provided. Externalities between consumers via the public good are shown to cause kinks in social indifference curves. As a result, a government restricted to income taxation should engineer enough inequality to ensure there are some non-contributors to the public good. Whether commodity taxation changes this conclusion depends on the extent to which consumers "see through" the government budget constraint. If they can, inequality should still be sought. When they cannot, in contrast to the case of an economy with only private goods, commodity taxation can be used in conjunction with income transfers to achieve the first-best. 相似文献

Summary. Given a production economy, we define union games by considering strategic behavior of the suppliers of factors. We refer to the Nash equilibria of this game as union equilibria. We analyze situations where the unemployment of factors is supported as a union equilibrium. The degree of unemployment depends on technological conditions. This allows us to model a source of unemployment which differs from the usual sources provided in the literature. We state a limit result that demonstrates that, as the market power of unions decreases, the corresponding sequence of union equilibria converges to the Walrasian equilibrium, that is, to full employment of factors. We also provide some examples that illustrate the main results.Received: 21 October 2004, Revised: 14 December 2004, JEL Classification Numbers:

Technology-forcing through environmental regulation 总被引:1,自引:0,他引:1

This paper analyzes the demand characteristics of innovation in pollution abatement and the interaction between a regulator and a polluter under a technology-forcing policy. Important demand-driven determinants of innovation in pollution control are examined, such as uncertainties surrounding unexplored technologies, the length of the compliance period and the maximum abatement costs the regulator is willing to accept. We derive the formal condition that the regulator balances the marginal utility of emissions reduction against the marginal disutilities of a longer compliance time and the increased uncertainty about the feasibility of a more stringent standard. 相似文献
