This article studies the ability of an N‐factor Gaussian model to explain the stochastic behavior of oil futures prices when estimated with the use of all available price information, as opposed to traditional approaches of aggregating data for a set of maturities. A Kalman filter estimation procedure that allows for a time‐dependent number of daily observations is used to calibrate the model. When applied to all daily oil futures price transactions from 1992 to 2001, the model performs very well, requiring at least three factors to explain the term structure of futures prices, but four factors to fit the volatility term structure. The model also performs very well for daily copper futures transactions from 1992 to 2001 and for out‐of‐sample daily oil futures transactions from 2002 to 2004. © 2006 Wiley Periodicals, Inc.

Abstract. This paper studies the effects of crises on human capital formation. Theoretically, a crisis undermines total factor productivity, which reduces the return to working and to accumulating physical capital. If the crisis is temporary, young agents will study now and work later. Human capital rises. To test our model we rely on inflation crises as our main empirical proxy. Using GMM panel procedures, our analysis for 86 countries in 1970–2000 confirms the positive effects of crises on human capital. Our main findings survive several robustness tests.

This paper studies the use of supplier's trade credit by firms in financial distress. Trade credit represents a large portion of firms’ short‐term financing and plays an important role in financial distress. We find that firms in financial distress use a significantly larger amount of trade credit to substitute for alternative sources of financing. Firms that are smaller, with less market power, and with more unique products tend to use more trade credit financing when in distress. We also find that firms that significantly increase their trade payables when in financial distress, experience an additional drop of at least 11% in sales and profitability growth over the previously documented 21% average drop for financially troubled firms. 相似文献

We consider the competition among quantity setting players in a linear evolutionary environment. To set their outputs, players adopt, alternatively, the best response rule having perfect foresight or an imitative rule. Players are allowed to change their behavior through an evolutionary mechanism according to which the rule with better performance will attract more followers. The relevant stationary state of the model describes a scenario where players produce at the Cournot‐Nash level. Due to the presence of imitative behavior, we find that the number of players and implementation costs, needed to the best response exploitation, have an ambiguous role in determining the stability properties of the equilibrium and double stability thresholds can be observed. Differently, the role of the intensity of choice, representing the evolutionary propensity to switch to the most profitable rule, has a destabilizing role, in line with the common occurrence in evolutionary models. The global analysis of the model reveals that increasing values of the intensity of choice parameter determine increasing dynamic complexities for the internal attractor representing a population where both decision mechanisms coexist. 相似文献

The present paper investigates the relationship between the involvement of family firms in R&D collaborations aimed at developing green solutions and the value of resulting innovations. To dig into this relationship, the moderating effects of two proximity dimensions (i.e., geographical distance and technological relatedness) are also assessed. Analyses are based on a sample of 156 joint patents classified into the “Alternative energy production” field, as defined by the International Patent Classification Green Inventory and successfully filed at the United States Patent and Trademark Office in the period 1997–2010 by publicly listed companies. According to our conjectures, results reveal a positive relationship between the involvement of family firms and green innovation value. Moreover, our findings show that this relationship is hindered when partners are geographically distant or technologically proximate. Eventually, we contribute to the literature on green innovation by unveiling under which conditions inter‐firm R&D collaborations lead to more valuable innovations. 相似文献

This research aims to contribute to the scientific debate about the lack of interlinkages between mandatory non-financial reporting and sustainable business models. For our purposes, a counter-accounting analysis was conducted on the non-financial reports of a sample of 145 Italian firms interested by the Directive 2014/95/EU effects. Specifically, the study adopts an empirical approach to evaluate environmental information transparency, which represents one of the main critical issues concerning the non-financial declarations prepared by European Italian Public Interest Entities (PIEs) to comply with Directive 2014/95/EU. The results highlight that corporate governance and report characteristics affect environmental transparency. Furthermore, the results confirm the overall attitude to avoid the disclosure of unfavourable or unavailable environmental information through impression management strategies. Finally, the analysis underlines the opportunities for policymakers to rethink mandatory non-financial reporting to sustain the ecological transition of European PIEs. 相似文献

The observed racial/ethnic gap in bank account ownership among older adults is substantial. We investigate socioeconomic, cognitive, and cultural barriers underling it. As additional potential barriers are accounted for, the residual gaps in financial inclusion with respect to Whites are reduced by 19% for blacks and 46% for Hispanics. We find that citizenship and “taste for privacy” play a limited role for both minority groups, while real asset ownership, health, cognitive ability, and cultural hurdles contribute substantially to the gap. For Hispanics, language barriers explain most of the gap, while neighborhood‐level socioeconomic characteristics are more salient for blacks. We also examine how the racial/ethnic composition of couples influences financial decisions. We estimate a significantly smaller residual gap between “mixed” and white couples than between minority and white couples. We provide empirical evidence suggesting that, other things equal, mixed couples are less concerned with the cultural/psychological barriers facing minority couples. 相似文献

We survey and assess the empirical literature on the sources of corruption Thanks to the improved availability of data, we
are able to produce an improved cross-country econometric model to test well-established and more recent hypotheses jointly.
We do not find that the common law system, or a past as a British colony predicts corruption. Our results support cultural
theories on the causes of corruption, and suggest that a medium-long exposure to uninterrupted democracy is associated with
lower corruption levels, while political instability tends to raise corruption. Our results also suggest that the diffusion
of newspapers helps to lower corruption levels.

Does Protestantism favour entrepreneurship more than Catholicism does? We provide a novel way to answer this question by comparing Protestant and Catholic minorities using Swiss census data. Exploiting the strong adhesion of religious minorities to their denomination’ ethical principles and the historical determination of the geographical distribution of denominations across Swiss cantons, we find that Protestantism is associated with a significantly higher propensity for entrepreneurship. The estimated difference ranges between 1.5 and 3.2 % points, it is larger the smaller the size of the religious minority, it is mainly driven by prime age male entrepreneurs and it stands up to a number of robustness checks. No effects are found when comparing religious majorities, suggesting that the implications of religious ethical norms on economic outcomes emerge only when such norms are fully internalized. 相似文献

This paper studies the trade receivables policy of distressed firms as the trade-off between the firm's willingness to gain sales and the firm's need for cash. We find that firms increase trade receivables when they have profitability problems, but reduce trade receivables when they have cash flow problems. We also find that a firm that significantly cuts its trade receivables when in financial distress will experience an additional drop of at least 13% in sales and stock returns over the previously documented 20% average drop for financially troubled firms. Moreover, the performance decline of a firm in financial distress is significantly higher if the firm cuts trade receivables than if it does not. 相似文献
