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.

Collateral constraints and the amplification mechanism 总被引:1,自引:0,他引:1
Arvind Krishnamurthy 《Journal of Economic Theory》2003,111(2):277-292
Kiyotaki and Moore (J. Polit. Economy 105 (1997) 211) have offered a theory for how common shocks to credit-constrained firms are amplified through changes in collateral values and transmitted as fluctuations in output. I clarify and extend their model by showing that their collateral amplification mechanism is not robust to the introduction of markets that allow these firms to hedge against common shocks. A theory of incomplete hedging is proposed in which the supply of hedging available in the economy is constrained by the aggregate value of collateral. I illustrate how the constraint reinstates amplification effects and discuss empirical implications of this new mechanism. 相似文献

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

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

We analyze a class of ‘large group’ Chamberlinian monopolistic competition models by applying different concepts of functional separability to the same set of first-order conditions for utility maximization. We show that multiplicatively quasi-separable (MQS) functions yield ‘constant relative risk aversion’ (CRRA), and, therefore ‘constant elasticity of substitution’ (CES), functions, whereas additively quasi-separable (AQS) functions yield ‘constant absolute risk aversion’ (CARA) functions. We then show that the CARA specification sheds new light on: (i) pro-competitive effects, i.e., profit-maximizing prices are decreasing in the mass of competing firms; and (ii) a competitive limit, i.e., profit-maximizing prices converge to marginal costs when the mass of competing firms becomes arbitrarily large. 相似文献

We study the effects of EU antidumping policy when foreign firms can ‘jump’ antidumping duties through foreign direct investment (FDI) in the EU. We show that duty jumping or duty pre-empting FDI occurs if the EU administration has broader objectives than protecting EU industry's profitability and if cost advantages of foreign firms are transferable abroad. The (expectation of) price undertakings reduces the incentives to engage in FDI and may even discourage FDI as long as products are not too differentiated. The results are consistent with recent empirical findings on antidumping jumping FDI. 相似文献

In this paper production, trade and welfare effects of European integration are discussed, with particular emphasis on the effects for the EC and EFTA. Insights from previous partial and general equilibrium analyses of the internal market are reviewed, and new model simulations are presented. In addition to the standard experiments of 1992 — as reduced trade costs and as full market integration — for the EC alone, and for the European Economic Area (EEA), an intermediate case, with full integration in the EC but only lower trade costs between the EC and EFTA, is analysed. All cases show that EFTA will benefit significantly from freer trade and closer integration with the EC. With regard to non-European regions, the simulations of European integration show some degree of trade diversion, but stylized model experiments indicate that a successful outcome of the Uruguay-round may more than offset the trade-diverting effects of 1992. 相似文献

We consider general economies in which rational agents interact locally. The local aspect of the interactions is designed to represent in a simple abstract way social interactions, that is, socioeconomic environments in which markets do not mediate all of agents’ choices, which might be in part determined, for instance, by family, peer group, or ethnic group effects. We study static as well as dynamic infinite horizon economies; we allow for economies with incomplete information, and we consider jointly global and local interactions, to integrate e.g., global externalities and markets with peer and group effects. We provide conditions under which such economies have rational expectations equilibria. We illustrate the effects of local interactions when agents are rational by studying in detail the equilibrium properties of a simple economy with quadratic preferences which captures, in turn, local preferences for conformity, habit persistence, and preferences for status or adherence to aggregate norms of behavior. 相似文献

The 1990s was a decade of increased economic integration. The decade also witnessed a sharp increase in cross-border mergers and acquisitions. From a theoretical perspective, the increase in international mergers in more integrated economies is rather puzzling. It is a well-established result that due to the “business stealing effect”, mergers in integrated markets are not likely to be profitable. A reasonable conjecture would therefore be that closer integration of markets would reduce the attractiveness of cross-border mergers and acquisitions. The present paper demonstrates that this is not necessarily the case: Economic integration may trigger cross-border acquisitions by reducing the business stealing effect and by reducing the reservation price of the target firm. The paper thus provides explanations to the observed increase in cross-border mergers in a world of more integrated economies. 相似文献
