This article is concerned with the measurement of jobless recoveries and the elements that may explain their emergence. We first introduce a measure that maps the various elements that define a jobless recovery into a single number that we label the jobless recovery depth. We then construct a database of 389 state‐level observations and study the cross‐sectional variations that emerge. We find that jobless recoveries in the United States are not a nation‐wide phenomena, but a local event confined within a cluster of states that expands slowly between 1975 and 2015. We find the state‐level evidence to be consistent with theories that link jobless recoveries to unusually long expansionary periods, less dynamic labor markets, and the advent of the great moderation. The evidence is not consistent with theories that link them to decreases in union power, increases in income inequality, or increases in health care costs.  相似文献

The Performance Effects of Business Groups in Russia   总被引:1,自引:0,他引:1  
This study analyses the impact of business group affiliation on firm performance during a time when business groups are newly formed, when the economic and institutional environment is changing, and when group survival is uncertain. Based primarily on a transaction cost approach, we develop two hypotheses, concerning profitability and risk sharing (redistribution) respectively. The positive profitability hypothesis proposes that company affiliation with a business group directly and positively affects the profitability of each affiliate. A positive direct effect emerges when each affiliate benefits from access to group resources. The redistribution hypothesis considers the simultaneous possibility that inter-affiliate transfers of resources through internal markets are designed to redistribute profits among group members. We argue that variance-reducing redistribution from strong to weak group members is linked to group survival in times of institutional change. Our empirical approach focuses on testing these two linked hypotheses (and their alternatives) using a relatively large, contemporary and time varying database of Russian firms. We also develop a framework that distinguishes among the four possible empirical outcomes associated with the hypotheses. Our results provide unambiguous support for the case where the impact of group membership on profitability is positive and redistribution is variance-reducing. We term this outcome Business Group Robustness, and contrast it with other possible empirical outcomes.  相似文献

'Distance' between organizational contexts has been a prime concern of scholarly research into international business strategies. We extend this research by exploring the complementary roles of institutional and human resource distances on foreign investors' entry strategies. Combining institutional and resource-based theories suggests that: (1) human resource differences complement institutional differences; (2) the effects of some aspects of distance are curvilinear; and (3) the impact of distance differs between first and subsequent entries. We find empirical support for these arguments on a unique dataset of foreign direct investment in six emerging economies that incorporates multiple host as well as multiple home countries.  相似文献

This article applies the testing procedures for measurement invariance using multigroup confirmatory factor analysis (MGCFA). It illustrates these procedures by investigating the factorial structure and invariance of the Portraits Value Questionnaire (PVQ, Schwartz et al.: J. Cross Cult. Psychol. 32(5), 519–542 (2001)) across three education groups in a population sample (N  =  1,677). The PVQ measures 10 basic values that Schwartz postulates to comprehensively describe the human values recognized in all societies (achievement, hedonism, self-direction, benevolence, conformity, security, stimulation, power, tradition and universalism). We also estimate and compare the latent means of the three education groups. The analyses show partial invariance for most of the 10 values and parameters. As expected, the latent means show that less educated respondents attribute more importance to security, tradition, and conformity values.  相似文献

We use a least squares metric to match the return pattern of a target stock with that of an out‐of‐sample‐twin. The twin with the smallest metric is found by a comprehensive period‐by‐period search of stocks in the Center for Research in Security Prices data set extending back to 1926. If technical analysis has value, targets of twins producing the highest returns in the twin postperiod should also have the highest performance in the target postperiod. Using a randomly selected sample of 66,000 return patterns, we find higher means for targets corresponding to the highest returning twin quintile. We also use regressions to risk adjust target returns and find that twin returns in the postmatch period significantly predict risk‐adjusted target returns.  相似文献

Contest rules are set up by administrators who frequently have discretionary power in specifying the details of these rules, i.e., they can bias the contest rules toward specific contestants in order to further their prime objective. We derive the optimal bias of the contest rule for a contest administrator, who is interested in maximizing the total efforts expended in the contest. The solution is obtained in closed form for a widely used class of n-person contest games. Setting the optimal bias has important implications: (i) there is never exclusion of strong players, instead there is (endogenously induced) inclusion of weak contestants; (ii) the contest administrator will optimally level the playing field by encouraging weak contestants, but he will not equalize the contestants’ chances unless they are identical; and (iii) at least three contestants will be active in equilibrium of the optimal contest, irrespective of heterogeneity.  相似文献

The Federal Communications Commission (FCC) spectrum auctions use a simultaneous ascending auction design. Bidders bid on numerous communication licenses simultaneously, with bidding remaining open on all licenses until no bidder is willing to bid higher on any license. With full revelation of bidding information, simultaneous open bidding allows bidders to send messages to their rivals, telling them on which licenses to bid and which to avoid. These strategies can help bidders coordinate a division of the licenses, and enforce the proposed division by directed punishments. We examine solutions to mitigate collusive bidding in the spectrum auctions, and then apply these ideas to the design of daily electricity auctions.  相似文献

Unlike other aspects of the American health experience, there is a current void of information on expensive illness experiences. This paper is designed to fill this void and prrsents an analysis of the incidence and cost of catastrophic illness in the United States. Catastrophic illness is defined as an illness episode for which a person incurs $5,000 or more of medical expenses in a calendar year. This information is used to provide a framework for focusing the debate about catastrophic and national health insurance.  相似文献
