This paper examines the relationships amongst volatility, total trading volume (TVOL) and total open interest (TOI) for three Taiwan stock index futures markets as well as the role of the latter two variables in the dynamics of GARCH modeling and forecasting. From both ex-post and ex-ante perspectives, we study this issue by using the VAR model and augmented GARCH-type models, respectively. For the GARCH-type models, we employ both symmetric and asymmetric models augmented with lagged logs in TOI and/or TVOL. We find that whether addition of these two variables helps the basic GARCH models predict future volatility depends upon the sample period examined for all three sets of futures. Nonetheless, the best three models for out-of-sample volatility forecasting in the MSE sense are generally the augmented models for all sub-intervals and all three futures contracts.  相似文献

This paper is concerned with the ownership structure of corporate debt from an institutional perspective. An attempt is made to identify the factors affecting bank debt use from an international sample of companies from Austria, Germany, Japan, Belgium, France, Italy, Holland, Spain, Portugal, Finland, Sweden and the USA. The results show that bank debt depends both on factors specific to each company and on institutional features of each country. More exactly, it is found that bank loans are related to firm size, to the quality and risk of the projects, and to the collateral. It is also found that a number of legal-institutional factors are impacting on the source of firms’ debt, such as creditor protection, firm disclosure requirements and law enforcement.  相似文献

An innovation which bypasses the need for instruments when estimating endogenous treatment effects is identification via conditional second moments. The most general of these approaches is Klein and Vella (J Econom 154:154–164, 2010), which models the conditional variances semiparametrically. While this is attractive, as identification is not reliant on parametric assumptions for variances, the nonparametric aspect of the estimation may discourage practitioners from its use. This paper outlines how the estimator can be implemented parametrically. The use of parametric assumptions is accompanied by a large reduction in computational and programming demands. We illustrate the approach by estimating the return to education using a sample drawn from the National Longitudinal Survey of Youth 1979. Accounting for endogeneity increases the estimate of the return to education from 6.8 to 11.2%.  相似文献

This paper is organized as follows: first, we show that the reference to the notion of group selection is coherent with the other parts of Hayek’s thought. Second, we develop the idea that recent works in terms of the emergence and evolution of social norms corroborate in part Hayek’s theses in this domain. Finally, we put to the fore some drawbacks in Hayek’s approach and propose means to solve them.

The effects of relationship quality on customer retaliation   总被引:2,自引:0,他引:2  
This research examines the effects of relationship quality (RQ) on customers' desires to retaliate after service failures. We posit that the effects of RQ are contingent upon the attributions customers make about the firm’s controllability over a service failure. Two competing hypotheses are examined and reconciled. The “love is blind” hypothesis posits that when low controllability is inferred, high RQ customers experience a lesser desire for retaliation than low RQ customers. On the other hand, the “love becomes hate” hypothesis specifies that when high controllability is inferred, high RQ customers experience a greater desire for retaliation than low RQ customers. The hypotheses are tested with a survey-based design and a partial least squares (PLS) model that incorporates a multiplicative latent construct.  相似文献

Until recently, risk-taking in investment decisions has been explained by cognitive biases and emotional urges. I would like to propose an alternative explanation, based on the work of Pierre Bourdieu, who links cultural capital to risk-taking. His concept of cultural capital has a very broad meaning, as it encompasses technical skills, aesthetic preferences, verbal facility, general cultural awareness, educational credentials, and artistic competencies. On theoretical grounds, one can assume that a high level of cultural capital enables the taming of uncertainty and allows for temporal horizons that cover longer terms. I test this hypothesis by conducting and analyzing a survey of 307 entrepreneurs. I define risk-taking in two ways: (i) in a somewhat mainstream way, on the basis of expected utility, and (ii) in a heterodox way, in a qualitative, context-dependent setting. I find that, in both cases, there seems to be a link between cultural capital and risk-taking. Furthermore, it seems to make financing issues more salient. I conclude by opening a discussion about the heterogeneity of entrepreneurs and their animal spirits.  相似文献
