This paper investigates the influence of human resource management practices on the likelihood that a firm performs in-house R&D. R&D is broadly interpreted as learning—a mechanism promoting absorptive capacity and supporting technology capability-building. Firms can choose between two learning strategies: they can exploit existing knowledge, or perform more complex explorations and acquire new knowledge. Different knowledge requirements associate with distinct R&D outcomes with varying degrees of novelty for the firm. Findings are supported with evidence from the pharmaceutical industry in Mexico. The analysis reveals positive linkages between human resource management practices and learning at firm level. The relationship is contingent on factors such as expected R&D outcomes, or the novelty of the knowledge required by the firm. The provision of training revealed the more consistent, positive influence on the likelihood that pharmaceuticals firms perform R&D in Mexico.  相似文献

For 15 years, former assistant football coach Jerry Sandusky used his Penn State University perquisites to lure young and fatherless boys by offering them special access to one of the most revered football programs in the country. He repeatedly used the football locker room as a space to groom, molest, and rape his victims. In February 2001, an eye-witness alerted Penn State’s top leaders that Sandusky was caught sexually assaulting a young boy in the showers. Instead of taking swift action against Sandusky, leaders began a cover-up that is considered one of the worst scandals in sports history. While public outcry has focused on the leaders’ silence, we focus on the talk that occurred within the organization by key personnel. Drawing from court documents and internal investigative reports, we examine two euphemism clusters that unfolded in the scandal. The first cluster comprises reporting euphemisms, in which personnel used coded language to report the assault up the chain of command. The second cluster comprises responding euphemisms, in which Penn State’s top leaders relied on an innocuous, but patently false, interpretation of earlier euphemisms as a decision-making framework to chart their course of (in)action. We use this case to demonstrate how euphemistic language impairs ethical decision-making, particularly by framing meaning and visibility of acts, encouraging mindless processing of moral considerations, and providing a shield against psychological and material consequences. Further, we argue that euphemism may serve as a disguised retort to critical upward communication in organizations.  相似文献

Abstract

Following Marglin and Bhaduri (1990 Marglin, S.A., and Bhaduri, A. “Profit Squeeze and Keynesian Theory.” In S.A. Marglin and J. Schor (eds.), The Golden Age of Capitalism. Reinterpreting the Postwar Experience. Oxford: Clarendon, 1990. [Google Scholar]), the purpose of this paper is to investigate empirically the interaction between income distribution and growth of aggregate demand during the 1951–89 period in Brazil. Applying Hein and Vogel’s (2008) methodology we conclude that the Brazilian economy showed a profit-led demand regime. In a context of high inflation, high concentration of markets, and wage control, retained profits were the main source to finance new capital. In this sense, we found a large sensitivity of investment relative to the wage share, a result that is compatible with a consumption pattern based on high income, which supported the growth trend with low wages observed during the period.  相似文献

This study implements a regular vine copula methodology to evaluate the level of contagion among the exchange rates of six Latin American countries (Argentina, Brazil, Chile, Colombia, Mexico, and Peru) from June 2005 to April 2012. We measure contagion in terms of tail dependence coefficients, following Fratzscher's (1999) definition of contagion as interdependence. Our results indicate that these countries are divided into two blocks. The first block consists of Brazil, Colombia, Chile, and Mexico, whose exchange rates exhibit the largest dependence coefficients, and the second block consists of Argentina and Peru, whose exchange rate dependence coefficients with other Latin American countries are low. We also found that most of the Latin American exchange rate pairs exhibit asymmetric behaviors characterized by nonsignificant upper tail dependence and significant lower tail dependence. These results imply that there exists contagion in Latin American exchange rates in periods of large appreciations, whereas there is no evidence of contagion during periods of currency depreciation. This empirical regularity may reflect the “fear of appreciation” in emerging economies identified by Levy‐Yeyati, Sturzenegger, and Gluzmann (2013). (JEL C32, C51, E42)  相似文献

The impact of past gains and losses on international investors' risk aversion is an important factor in the propagation of financial shocks across countries. We first present a stylized model illustrating how changes in investors' risk aversion affect portfolio decisions and stock prices. We then examine empirically the behavior of international mutual funds. When funds' returns are below average, they reduce their exposure to countries in which they were overweight and vice versa. An index of “financial interdependence” that reflects the extent to which countries share overexposed funds helps explain the pattern of stock market comovement across countries and the pattern of contagion during crises.  相似文献

We derive a closed-form solution for the optimal portfolio ofa nonmyopic utility maximizer who has incomplete informationabout the alphas or abnormal returns of risky securities. Weshow that the hedging component induced by learning about theexpected return can be a substantial part of the demand. Usingour methodology, we perform an "ex ante" empirical exercise,which shows that the utility gains resulting from optimal allocationare substantial in general, especially for long horizons, andan "ex post" empirical exercise, which shows that analysts’recommendations are not very useful.

We derive a formal expansion for a distribution in terms of another distribution. As a particular case we get the formal Edgeworth expansion. The heuristic procedure that we present is used to obtain approximations for distribution functions of the Cramér-von Mises and Watson goodness-of-fit statistics. Finally we compare our results with some obtained in the literature.  相似文献

Abstract

The intent of this research is to propose and analyse a set of policies in the construction industry to enhance social development. First, the paper shows the connections between the development of small and medium enterprises (SMEs) and social entrepreneurship (SE), the reduction of the leakage, and then the generation of social value (SV) for sustainable regional development. For that, the article analyses briefly the literatures on SE and leakage, and focuses on the relevance of SME and social entrepreneurs as promoters of SV creation and development. Second, the paper proposes a framework and proposes a set of 20 policies aimed to reduce leakage, reinforce SMEs and entrepreneurship and also to promote SE behaviour by the diverse economic agents in the construction industry, in order to increase the generation of SV and sustainable development. Then, the paper analyses the acceptability, feasibility and viability of these proposed polices, which can be useful for academics and practitioners. For that, the study uses the Delphi methodology, applied to an expert-group of 23 professionals (representatives of the private and public sector) belonging to the Colombian construction industry. The results emphasize the relevance of the development of local incumbents and the social focus of firms to increase the generation of SV. Oppositely, policies interfering economic freedom and free trade receive the lowest rates in the three criteria considered.  相似文献

This paper examines a three-period model of an investment decision in a network industry characterized by demand uncertainty, economies of scale and sunk costs. In the absence of regulation we identify the market conditions under which a monopolist decides to invest early as well as the overall welfare generated by this decision. In a regulated environment, we consider a vertically integrated network provider that is required to provide access to downstream competitors and compare two distinct access pricing methodologies: the Efficient Component Pricing Rule (ECPR) and the Option to Delay Pricing Rule (ODPR). We identify the welfare-maximizing access prices using the unregulated market output as a benchmark and show that optimal access regulation depends on market conditions (that is, the nature of demand) with two possible outcomes: (i) access prices that provide a positive payoff to the incumbent, that is, provide a positive compensation to account for the option to delay; and (ii) access prices that yield a zero payoff to the incumbent. Moreover, unlike the earlier literature that argues in favor of an ECPR-type methodology to account for the interaction between irreversibility and demand uncertainty, we find that, except under very specific conditions, an access price that accounts for the option to delay value is welfare-superior to the ECPR.   相似文献
