In this paper, we look for asymmetries in the Spanish business cycle. To that end, we firstly propose an easy nonparametric
testing procedure to test for symmetry based on a Pearson's chi-squared statistic, which we call P-test. Then, we test for two popular forms of asymmetry, deepness and steepness, using a battery of nonparametric tests. In
addition, we analyse possible complementarities between the tests used in this paper, and we compute p-value adjustments for multiple tests. 相似文献

Summary. In this paper, I study the existence of Sunspot Equilibria in a general framework whose dynamics allow for the presence of
predetermined variables in the system. The main motivation for this research comes from the fact that previous studies did
not allow for such predetermined variables which, nevertheless, appear quite naturally in economic models. I show, for a non-negligible
subset of dynamics with predetermined variables verifying usual assumptions, the existence of Stationary Sunspot Equilibria
fluctuating between an arbitrary finite number of states arbitrarily close to a steady state.

Abstract. This paper contributes to the growing literature that analyses the Spanish publishing performance in Economics throughout
the 1990s. Several bibliometric indicators are used in order to provide Spanish rankings (of both institutions and individual
authors) based on Econlit journals. Further, lists of the ten most influential authors and articles over that period, in terms of citations, are reported.
We are grateful to many colleagues who made very useful remarks to preliminary versions of this paper, as well as to two anonymous
referees. We are particularly indebted to Xavier Sala-i-Martín, without whose invaluable help this work would not have been
possible. All errors or omissions are of our exclusive responsibility. 相似文献

国有企业民营化的均衡模型 总被引:39,自引:1,他引:39
本文是来自于中国近年来实行民营化改制实践的一个理论结晶。该研究在中国特定的渐进改革基础上 ,讨论了民营化发生的原因和阻力 ,以及国有企业的利益相关者在改制过程中的利益权衡行为 ,并根据它们的相互关系和目标行为建立了民营化的均衡模型。模型的核心是企业家的最优目标函数 ,这是关系到企业能否实现成功改制的关键。模型的约束条件反映了利益相关者的基本利益保障 ,不会由于改制而受到损害。因此 ,均衡条件的满足表明了最优化改制的实现。通过对模型的分析发现 ,能够满足民营化最优均衡的退出条件 ,就是国有企业退出的最佳时机选择。企业净资本价值、企业家对股权的收购值与职工补偿值之间的合理比例的区间 ,是形成民营化均衡模型的最优解的取值范围。模型的政策含义在于纠偏作用 ,尤其是政府实际的退出时机与改制均衡的最佳退出时机的不一致 ,对于职工利益的损害或缺乏企业家最优目标行为的改制 ,都是脱离了最优轨道的结果 ,需要进行纠正 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.

We analyze the impact of product diversification on performance. This topic has been discussed in the literature, and there
is no consensus so far as to the significance or the direction of the impact. Performance is measured using Tobin's q for
a sample of 103 large, non-financial Spanish firms (1992–1995). Diversification is measured by means of a categorical variable,
as suggested by Varadarajan. The principal results indicate that the firms with intermediate levels of product diversification
have the highest performance, while the firms with low and high levels of diversification show significantly lower performance,
which performance is not significantly different between them. 相似文献

This paper presents a methodology for the formulation and testing of economic growth models. The model selected includes
two production sectors with physical and human capital accumulation. These capital stocks are associated with spillover effects
in the production of the physical good and in the accumulation of both factors. 相似文献

The objective of this paper is to adjust a traditional total factor productivity (TFP) measure for the direct effect of environmental regulation on material and capital input. For this purpose we consider the fact that part of material input and pollution abatement capital have not been used to increase output but to cover the cost of using the environment as a factor of production. Therefore TFP growth rates are lower if part of the material input is allocated to abatement activities instead of producing output. We propose to treat compliance with environmental regulation as an unproductive input linked to the use of productive material input. Our aim is to answer and discuss two questions: How to measure the effect of environmental regulation on TFP, and does the effect matter. We examine data from 1975–1991 for ten pollution intensive German industries.We would like to thank Cornelia Oßwald for valuable research assistance. We are especially grateful to two anonymous referees for many helpful comments. 相似文献

This paper analyses the effects of partially revocable endogenous commitments of a seller in a negotiation with a deadline.
In particular, we examine when commitment is a source of strength, a source of inefficiency and when it does not affect the
bargaining outcome at all. We show that when commitment possesses a minimum amount of irrevocability this crucially determines
the bargaining outcome. In the bilateral bargaining case, commitment becomes a source of inefficiency since it causes a deadline
effect. In the choice of partner framework, however, the deadline effect disappears and there is an immediate agreement and,
moreover, commitment becomes a source of strength since it increases the seller's equilibrium payoff by triggering off competition
between the buyers. 相似文献
