Despite the impressive development of substantive theories in entrepreneurship, without the development of measurement theories, further advancement of the field is problematic. In particular, the notion of opportunities, central to entrepreneurship research, requires adequate macro-level operationalization. We demonstrate how to employ data envelopment analysis (DEA) to operationalize not only innovative opportunities, but also technological arbitrage opportunities. We provide an illustrative example based on a sample of 66 countries during the period of 1993–2002. We include estimates of innovative and arbitrage opportunities for possible use by other scholars, discuss the promise and limitations of such estimates, demonstrate how both innovative and arbitrage opportunities correlate with the rates of entrepreneurial activity, and suggest several possible directions for future research. 相似文献

Political Stock Markets and Unreliable Polls 总被引:1,自引:0,他引:1
A political stock market (PSM) clearly beat the polls in predicting the outcome of a Swedish referendum on whether or not Sweden should join the European Union. In fact, polls were unable to make such predictions since the number of undecided respondents always far exceeded the observed YES/NO margin. However, an obstacle to PSMs serving as a superior forecasting instrument is that they can be sensitive to price distortions - by interest groups that may wish to effectuate, and pay for, such distortions - or forecast competitions tied to PSM trade gains, the latter of which was tested here. 相似文献

Western theories on creativity emphasize the importance of access to resources and the generation of innovations as a source of sustainable competitive advantage for firms. However, perhaps the emphasis on slack resources and the firm as the level of analysis may be less appropriate for understanding the benefits of individual creative problem solving in resource-poor environments of the east; focusing solely on the firm is not sufficiently inclusive and may underestimate the benefits of creative problem solving under resource scarcity. Through an inductive interpretive case study of 12 problem solvers in the highly resource-poor environment of rural India, we identified the antecedents, dimensions and duality of outcomes for an Indian cultural source of creative problem solving called jugaad. Jugaad relies on assertive defiance, trial-and-error experiential learning and the recombination of available resources to improvise a frugal quick-fix solution. Our inductive framework provides new insights into the dual outcomes of creative problem solving from an eastern perspective; jugaad is unlikely to be a source of competitive advantage for firm growth but represents a source of enhanced wellbeing for inclusive growth. 相似文献

This paper proposes an IV‐based panel unit root test that is general enough to accommodate general error serial and cross‐section dependence, and a potentially nonlinear deterministic trend function. These allowances make the new test one of the most general around. It is also very simple to implement. Indeed, the IV statistic is asymptotically invariant to not only to all nuisance parameters characterizing the dependence of the errors and the true trend function, but also the deterministic specification of the fitted test regression. 相似文献

The study examines whether factors related to customers' perception of employees' behavior in terms of customer perceived role ambiguity, role overload and customer-employee rapport influence the development of brand equity in the professional service context. 632 customers of one of the Big Four auditing companies participated in the study. The results of structural equation modeling show negative effects of role ambiguity and role overload on brand associations, perceived quality and brand loyalty, which constitute brand equity. The findings indicate a positive effect of customer-employee rapport on the enhancement of B2B brand equity. However, the negative influences of role ambiguity and role overload on customer-employee rapport transfer detrimental indirect effects on brand equity. The study contributes to an understanding of how the real interaction between service providers and customers can influence brand equity in the professional service setting. 相似文献

This article makes an analytical study of the effects of the presence of both common and idiosyncratic stochastic trends on the pooled least squares estimator. The results suggest that the usual result of asymptotic normality depends critically on the absence of the common stochastic trend. 相似文献

Crossed and internalized upstairs trades are analysed in a dataset in which institutional investors can be identified. Earlier findings that upstairs trading is uninformed, taps into unexpressed liquidity, and does not affect market quality are revisited. The permanent price effect of crossings and internalized upstairs trades is significantly lower than that of limit order book trades due to the fact that the least informed institutional trades are routed upstairs. Crossed and internalized trades affect the depth and transaction costs in the limit order book and a greater reliance is placed on the upstairs market when liquidity is low and volatility is high. 相似文献

Does the Measurement of Intra-Industry Trade Matter? — This paper discusses different methods of capturing the main aspects of the Chamberlin-Heckscher-Ohlin-Samuelson model. Of particular interest are the distinction between horizontal and vertical intra-industry trade, the adjustment of aggregation biases, and the definition of inter- and intra-industry specialization at product level. The main findings are that it is important to disentangle horizontal and vertical intra-industry trade, and to consider specialization patterns within refined product groups. Moreover, there is a nonlinear relationship between intra-industry trade and economies of scale that may explain contradictory results in the literature. 相似文献
