Si danno limitazioni inferiori e superiori per il valor medio del tasso implicito di operazioni finanziarie aleatorie di una classe determinata. Per l’ottenimento di alcune disuguaglianze si fa uso di una versione generalizzata della ben nota disuguaglianza di ?eby?ev tra medie con diverse ponderazioni che viene dimostrata in appendice e che vale anche per distribuzioni di probabilitá con componenti discreta e continua congiuntamente. 相似文献

Recent literature on competition in regulation concludes that the iterative adjustment that may start with mutual recognition
is an open-ended process. This paper shows that, even without acceptance of reciprocal minimum standards, a process of iterative
adjustment may be triggered by the coexistence of foreign goods with high standard levels and domestic goods with relatively
low standard levels. Focusing on the case of international heterogeneity of levels of a specific standard, the paper offers
an intuitive counter-argument to the fear that free trade necessarily implies a “race to the bottom“ of standard levels. 相似文献

THE PREDICTABILITY OF AGGREGATE CONSUMPTION GROWTH IN OECD COUNTRIES: A PANEL DATA ANALYSIS 下载免费PDF全文
We examine aggregate consumption growth predictability. We derive a dynamic consumption equation which encompasses relevant predictability factors: habit formation, intertemporal substitution, current income consumption and non‐separabilities between private consumption and both hours worked and government consumption. We estimate this equation for a panel of 15 OECD countries over the period 1972–2007, taking into account parameter heterogeneity, endogeneity and error cross‐sectional dependence using a GMM version of the common correlated effects mean group estimator. Small‐sample properties are demonstrated using Monte Carlo simulations. The estimation results support income growth as the only variable with significant predictive power for aggregate consumption growth. Copyright © 2013 John Wiley & Sons, Ltd. 相似文献

In this study, we examine the effect of mutual fund connections, through managerial sharing, on performance and stock holding commonalities. Our analysis of return correlations and portfolio holdings indicates that more interconnected funds tend to buy and sell similar stocks, hence increasing the similarity of portfolio holdings and undermining the distinctiveness of their investment strategy. Our results also indicate that highly connected funds significantly underperform weakly connected funds by about 1.4% on a yearly risk‐adjusted basis. We show that fund family performance is unaffected by the intensity of fund connections, and that greater fund connections could significantly enhance family‐level profit margins. 相似文献

By comparing siblings attending the same school at different points in time, we investigate whether the effect of peer quality on long-term labor market outcomes varies with parental background. We find that exposure to better peers—who have higher mean parental education—increases lifetime earnings of disadvantaged students, coming from families with low parental education, but penalizes privileged students from better educated families. These results suggest that desegregation policies that allocate disadvantaged students to schools with better peers produce long-term benefits. We discuss mechanisms and show that human capital accumulation, ordinal rank and network effects contribute to explain our findings. 相似文献

ABSTRACT Considering the recent improvements in services innovation and productivity performance, the aim of the article is to analyze if they can act as a new growth driver for Latin American countries. For that, we review the literature on services and structural change in two stages. First, we apply a bibliometric methodology to identify the main trends in literature. Second, we analyze in-depth a smaller set of papers in order to extract the main lessons regarding three aspects of our question: (i) services and productivity growth, (ii) new opportunities for innovation in services and (iii) relation between services and manufacturing through servitization process. The results show that productivity and innovation growth in services are concentrated in only a few branches. Besides this, services performance depends on their links with manufacturing activities. We conclude that the current Latin American servitization process clausure opportunities for developing instead of opening them. 相似文献

We study the effect of tenure on earnings instability in Italy using the reforms of temporary employment contracts, which affected the average tenure of workers differentially across cohorts. We develop a model of earnings dynamics, and we exploit the variation of tenure and instability over time and across birth cohorts to estimate policy‐relevant parameters. Our results indicate that each year of tenure on the job reduces earnings instability by 11 percent; the drop is faster in the first three years of the match. Workers on a temporary contract have an earnings instability up to 100 percent higher than workers on a permanent contract. 相似文献

In the context of univariate GARCH models we show how analytic first and second derivatives of the log-likelihood can be successfully employed for estimation purposes. Maximum likelihood GARCH estimation usually relies on the numerical approximation to the log-likelihood derivatives, on the grounds that an exact analytic differentiation is much too burdensome. We argue that this is not the case and that the computational benefit of using the analytic derivatives (first and second) may be substantial. Furthermore, we make a comparison of various gradient algorithms that are used for the maximization of the GARCH Gaussian likelihood. We suggest the implementation of a globally efficient computation algorithm that is obtained by suitably combining the use of the estimated information matrix with that of the exact Hessian during the maximization process. As this would appear a straightforward extension, we then study the finite sample performance of the exact Hessian and its approximations (that is, the estimated information, outer products and misspecification robust matrices) in inference. 相似文献
