Does Collateral Help Mitigate Adverse Selection? A Cross-Country Analysis

In this paper, we empirically investigate whether collateral mitigates adverse selection problems in a loan market. Theory predicts a negative relation between the presence of collateral and the interest spread of a loan. However, bankers??view and most empirical evidence contradict this prediction and support the observed-risk hypothesis instead. We provide new evidence from a sample of 4,940 bank loans from 31 countries. We test whether the degree of information asymmetry affects the positive link between collateral and the loan spread and find that a greater degree of information asymmetry reduces this positive relation. This finding provides support for both the adverse selection and observed-risk hypotheses.     

On the law of one price

We consider the standard discrete-time model of a frictionless financial market and show that the law of one price holds if and only if there exists a martingale density process with strictly positive initial value. In contrast to the classical no-arbitrage criteria, this density process may change its sign. We also give an application to the CAPM.Received: November 2003, Mathematics Subject Classification (2000): 60G44JEL Classification: G13, G11Freddy Delbaen: This research was done during the stay of the author at Université de Franche-Comté.     

Robust desmoothed real estate returns

This research starts from the observation that common desmoothing models are likely to generate some extreme returns that will distort risk measurement and hence can lead to investment decisions that are suboptimal relative to those that would be made if a transaction‐based index were available. Thus, we propose to improve the desmoothing models by incorporating a robust filter into the procedure. We report that in addition to properly treating for smoothing, the method prevents the occurrence of extreme values. As shown with U.S. data, our method leads to desmoothed series whose characteristics are akin to those of transaction‐based indices.     

Do Leveraged Firms Underinvest in Corporate Social Responsibility? Evidence from Health and Safety Programs in U.S. Firms

The explosion of health-related costs in U.S. firms over more than a decade is a huge concern for managers. The initiation of Health and Safety (H&;S) programs at the firm level is an adequate Corporate Social Responsibility (CSR) initiative to contain this evolution. However, in spite of their documented efficiency, firms underinvest in those programs. This appears as a puzzle for health economists. In this paper, we uncover a strong negative relation of financial leverage to the implementation of H&;S programs. The negative impact of debt on investment and CSR activities is generally interpreted as an efficient disciplinary effect of debt on managers. H&;S are particularly well suited to revisit this evidence, given their strong profitability and homogeneity across firms. Very interestingly, the negative effect is stronger for firms with high free cash flows, for which debt is used to prevent overinvestment. This strongly suggests that debt, while disciplining managers, also discourages investments which are valuable both for firms and society.     

International financial integration and real exchange rate long-run dynamics in emerging countries: Some panel evidence

The aim of this article is to provide new empirical evidence on the impact of international financial integration on the long-run Real Exchange Rate (RER) in 39 developing countries belonging to three different geographical regions (Latin America, Asia and MENA). It covers the period 1979–2004, and carries out ‘second-generation’ tests for non-stationary panels. Several factors, including international financial integration, are shown to drive the long-run RER in emerging countries. It is found that the new financial environment characterised by international financial integration leads to a depreciation of the RER in the long run. Further, RER misalignments take the form of an under-valuation in most MENA countries and an over-valuation in most Latin American and Asian countries.     

Syndicated loans in emerging markets

There has been a considerable expansion of the volume of syndicated loans in emerging markets in the recent years. We provide the first analysis of the determinants of the decision of banks to syndicate a loan on a sample of loan facilities from 50 emerging countries. We show the significant role of loan characteristics and of financial development, banking regulation, and legal institutions, in the decision to syndicate a loan. We support the efforts of authorities to increase banking competition and efficiency, and to implement binding banking regulation on capital requirement to promote the expansion of syndicated loans.     

High-Tech Corporatism: Management-Employee Relations in U.S. Electronics Firms, 1920s-1960s

In this article I examine corporative management practices inelectronics firms in Boston and in Silicon Valley from the 1920sto the 1960s. Managers in several key firms developed thesepractices in response to political and professional ideologiesand as a way to address the problems of hiring, using, and retaininga highly skilled work force. They did this independently ofthe welfare capitalism plans of corporations such as EastmanKodak and before the guru theorists and work empowerment programsof the 1960s. The corporatist methods first developed in Bostonand further refined in Silicon Valley later diffused to mostU.S. firms in the software, computer, Internet, and biotechnologyindustries.     

Existence of Nash networks in one-way flow models

This paper addresses the existence of Nash equilibria in one-way flow models in a number of different settings. In these models players form costly links with other players and obtain resources from them through the directed path connecting them. We find that heterogeneity in the costs of establishing links plays a crucial role for the existence of Nash networks. The paper also provides conditions for the existence of Nash networks in models where costs and values of links are heterogeneous. We would like to thank an anonymous referee for useful suggestions. We would also like to thank Hans Haller and participants at the AEA Meetings 2007 for helpful comments.

Semiparametric hedonic price models: assessing the effects of agricultural nonpoint source pollution

In the area of environmental analysis using hedonic price models, we investigate the performance of various nonparametric and semiparametric specifications. The proposed model specifications are made up of two parts: a linear component for house characteristics and a non‐(semi)parametric component representing the nonlinear influence of environmental indicators on house prices. We adopt a general‐to‐specific search procedure, based on recent specification tests comparing the proposed specifications with a fully nonparametric benchmark model, to select the best model specification. An application of these semiparametric models to rural districts indicates that pollution resulting from intensive livestock farming has a significant nonlinear impact on house prices.
