This article explores the existence of seasonality in the tails of stock returns. We use a parametric model to describe the returns, and obtain a proxy of the innovation distribution via a pre-processing model. Then, we develop a change-point algorithm capturing changes in the tails of the innovations. We confirm the good performance of the procedure through extensive Monte Carlo experiments. An empirical investigation using US stocks data shows that while the lower tail of the innovations is approximately constant over the year, the upper tail is larger in Winter than in Summer, in 9 out of 12 industries.  相似文献

This paper discusses the occurrence of skill‐enhancing technology import, namely, the relationship between imports of embodied technology and widening skill‐based employment differentials in low‐ and middle‐income countries. Generalized method of moments (GMM) techniques are applied to an original panel dataset comprising 28 manufacturing sectors for 23 countries over a decade. Econometric results provide robust evidence of the determinants of widening employment differentials in low‐ and middle‐income countries. In particular, the proposed empirical evidence indicates capital–skill complementarity as a possible source of skill bias, while imported skill‐enhancing technology emerges as an additional driver of increasing demand for the skilled workers in these countries.  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

We develop a theory’ and empirical test of how the legal system affects the relationship between venture capitalists and entrepreneurs. The theory uses a double moral hazard framework to show how optimal contracts and investor actions depend on the quality of the legal system. The empirical evidence is based on a sample of European venture capital deals. The main results are that with better legal protection, investors give more non-contractible support and demand more downside protection. These predictions are supported by the empirical analysis. Using a new empirical approach of comparing two sets of fixed-effect regressions, we also find that the investor’s legal system is more important than that of the company in determining investor behavior.  相似文献

Sorry Winners   总被引:1,自引:0,他引:1  
Bidders who receive both “common-value” and “private-value” signals about the value of an auction prize cannot fully infer their opponents’ information from the bidding. So bidders may overestimate the value of the prize and, subsequently, regret winning. When multiple objects are on sale, bidding in an auction provides information relevant to the other auctions, and sequential auctions are more vulnerable to overpayment and winners’ regret than are simultaneous auctions. With information inequality among bidders, the seller’s revenue is influenced by two contrasting effects. On the one hand, simultaneous auctions reduce the winner’s curse of less informed bidders and allow them to bid more aggressively. On the other hand, sequential auctions induce less informed bidders to bid more aggressively in early auctions to acquire information.   相似文献

Technology does not have intrinsic value: obtaining competitive advantage from it and transforming it into profits requires a business model based on the application of competencies and dynamic capabilities, and the ability to select and apply appropriate resources. Innovative 3-D printing technology appears to be dependent on a new business model based on the ability to structure and integrate creative inputs, crowdsourcing processes, and market distribution networks. This new business model is being used by design enterprises that employ 3-D printing technology in order to enrich their service portfolio or to inaugurate completely new business lines. This paper analyzes how the use of new 3-D printing technology in design enterprises is coupled with proper business model components. Through a qualitative analysis of three cases - Quirky, i.materialise and Fab-Lab - the authors develop four propositions on a number of factors that contribute to business model effectiveness in design ventures using 3-D printing technology.  相似文献

This paper discusses the effects of the existence of natural and/or exogenously imposed thresholds in firm size distributions on estimations of the relation between firm size and the variance in firm growth rates. We argue that these estimations are upwardly biased whenever the threshold operates on the same proxy that is used to calculate the growth rates. We show the potential impact of the bias on simulated data, suggest a methodology to improve these estimations, and present an empirical analysis on Dutch firms. The only stable relation that emerges is the negative relationship between firm size and growth rate variance.  相似文献
