This paper investigates the dynamics between the financial freedom counterparts of the economic freedom index drawn from the Heritage Foundation database and bank efficiency levels. We rely on a large sample of commercial banks operating in the 27 European Union member states over the 2000s. After estimating bank-specific efficiency scores using Data Envelopment Analysis (DEA), we develop a truncated regression model combined with bootstrapped confidence intervals to test our main hypotheses. Results suggest that the higher the degree of an economy’s financial freedom, the higher the benefits for banks in terms of cost advantages and overall efficiency. Our results also show that the effects of financial freedom on bank efficiency tend to be more pronounced in countries with freer political systems in which governments formulate and implement sound policies and higher quality governance.  相似文献

This paper provides a comprehensive study of the syndicate structure and its relationship to information asymmetry and loan spread by using principal component analysis on a large set of 40 structure-related variables. A total of six structure components are identified and related to syndicate quality, syndicate members’ heterogeneity or share concentration, lead arranger’s characteristics, lead lender’s or syndicate’s location, lender–borrower relationships, and lead institution type. In multivariate settings, all six components are significant determinants of loan spread, either directly or indirectly through their impact on other components. Lead share retention, previous lender–borrower relationships and syndicate quality are shown to be bilaterally related to loan spread. Structure components differ regionally, which can provide an explanation for the European pricing discount observed in the literature. An Asian discount is observed and cannot be explained by structure differences.  相似文献

This paper provides a review and evaluation of different food‐risk prioritization and management frameworks that have been developed by governmental food‐safety authorities, regulatory agencies and non‐governmental institutions worldwide. It emphasizes the need for a new science‐ and risk‐based system approach to microbial risk prioritization. We find that most studies and projects argue for a systematic and multi‐disciplinary approach to risk prioritization but nevertheless lack it. Human and public health issues have constituted the core focus of food‐risk analysis in food‐borne risk prioritization studies, where the majority of studies use the concept of disease burden. Even though it is widely recognized that economic and market‐level impacts of microbial hazards and preventive interventions to reduce food‐borne risks are crucial to the performance of industries and markets, they are almost never accounted for in risk prioritization frameworks.  相似文献

Changes in labor market institutions and the increasing integration of the world economy may affect the volatility of capital and labor incomes. This article documents and analyzes changes in income volatility using data for 11 industrialized countries, 22 industries and 35 years (1970–2004). The article has four main findings. First, the unconditional volatility of labor income has declined in parallel to the decline in macroeconomic volatility. Second, the industry‐specific, idiosyncratic component of labor income volatility has hardly changed. Third, cross‐sectional heterogeneity is substantial. If anything, the labor incomes of high‐ and low‐skilled workers have become more volatile relative to the volatility of capital incomes. Fourth, the volatility of labor income relative to the volatility of capital income declines in the labor share. Trade openness has no clear‐cut impact.  相似文献

Conditional Cooperation and Voluntary Contributions to Public Goods   总被引:10,自引:0,他引:10  
We compare a partners condition , where the same small group of subjects plays a repeated public good game, to a strangers condition , where subjects play this game in changing group formations. From the first period onward, subjects in the partners condition contribute significantly more to the public good than subjects in the strangers condition. Strangers' contributions show continual decay, while partners' contributions fluctuate on a high level prior to decreasing in the final periods. We interpret subjects' behaviour in terms of conditional cooperation which is characterized by both future-oriented and reactive behaviour.

There is some concern that the unobserved preference heterogeneity in random utility maximization theory-based discrete choice experiment modelling is an important source of error variability. The randomness in utility is often interpreted as interpersonal preference heterogeneity but it can also be intrapersonal random variation in preferences. We compare utility maximization and regret minimization-based choice models’ sensitivity to individual heterogeneity, examine differences between two consecrated models and validate with empirical illustrations. We use frequency of category (public, semi-private, and private) of bed chosen from Swiss cross-sectional datasets (2007–2012) to compare two approaches – utility maximization and regret minimization by applying multinomial logit (MNL) models in regard to the variances in utility (regret) function, goodness-of-fit and predicted marginal effects (pseudo-elasticity) of additional payment. We find parameters with the same sign and estimates with almost same order of magnitude in both the approaches. The statistical significance of attribute effects is consistent in all variants of utility -based MNL models while effects of different attributes are significant only in heteroskedastic extreme value (HEV) variant of regret-based MNL models. This empirical illustration suggests that HEV variant of regret-based models perform better in capturing attribute effects in choice behaviour.  相似文献

Developing adaptation strategies for deltaic and coastal regions is a major challenge, due to future uncertainties of climate change and complexity of the social–ecological systems to be managed. This paper investigates how desirable futures or normative scenarios approaches, in particular backcasting, can be used to develop more robust climate strategies in coastal regions. The paper develops a methodology in which participatory backcasting and adaptive management are combined, and its applicability is demonstrated for the Breede–Overberg coastal region in South Africa where a catchment management strategy has been developed. It is concluded that the methodology offers an adequate framework for developing and implementing long-term climate adaptation strategies and policies, including a transition management scheme for intermediate assessments.  相似文献

When modelling rating transitions as continuous-time Markov processes, in practice, time-homogeneity is a common assumption, yet restrictive, in order to reduce the complexity of the model. This paper investigates whether rating transition probabilities change after the origination of debt. Accordingly, we develop a likelihood-ratio test for the hypothesis of time-homogeneity. The alternative is a step function of transition intensities. The test rejects time-homogeneity for rating transitions observed over 7 years in a real corporate portfolio. Especially 1-year transition probabilities increase over the first year after origination. This time effect suggests that banks should manage their credit portfolios with respect to the age of debt.   相似文献

Recently, German insurers are becoming increasingly interested in assessing and modelling risks related to new business and lapses. The final report of a DAV (German actuarial association) working party on stochastic models for German life insurance companies, released end of 2005, includes some basic approaches for this purpose. However, so far no systematic empirical research has been carried out which provides evidence for an appropriate calibration of such models. This article contributes to closing the gap. It presents the main results of an empirical analysis on the influence of policyholders’ profit participation on new business and lapses based on data about 87 German life insurance companies from 1995—2004. Analyses of regression and correlation were performed for various definitions of the explanatory variable ?profit participation“ (more precisely: the spread to some average value) and with diverse reference parameters for new business and lapses, also considering different types of life insurance. Ultimately, the exploration scarcely yielded evidence for a significant general correlation between policyholders’ profit participation and new business or lapses. However, because of the individuality of life insurance business such an evaluation of historical data can certainly only be regarded as a building block for the overall picture, as is also explained in the paper in some more detail.  相似文献

This paper deals with Joan Robinson's contributions to the issue of technical progress and her attempts at treating this subject in accordance with the Keynesian theory of employment and income distribution, mainly in the long run. The paper aims to review this aspect of her work and to establish a systematisation and a formalisation of her approach. At the same time, the paper exposes the problems she faced—but did not always solve. Looking through her main contributions, the paper concludes that she used different criteria for the classification of innovations and that they depended on the specific situations described by the models in which she used the classification.  相似文献
