Contradictions in fsQCA

The lack of support for contradictions in fsQCA limits the method’s usefulness for conducting inductive research. In this paper, I describe how to extend fsQCA to accommodate contradictory conditions. I review kirq (Reichert and Rubinson 2011), a new software package for QCA that includes support for fuzzy-set contradictions. For researchers using software that does not support fuzzy-set contradictions, I describe how to identify them by hand.     

Contextualized Project Management Practice: A Cluster Analysis of Practices and Best Practices

The specificity of project management in different contexts and industries is recognized, but little empirical research encompasses a sufficiently broad range of contexts and project types to precisely identify these specificities. This article adopts such a wide perspective based on a large sample of data from an ongoing empirical investigation of project management practice. Contextual archetypes are identified (i.e., clusters of experienced practitioners that share similar organizational and project contexts). Archetypes of contextualized practice are then investigated through the study of the extent of use of empirically identified toolsets in each cluster. The results empirically confirm some well‐known assumptions about practice but also sharpen the knowledge and understanding of practice in real complex multidimensional contexts. A new concept of “performing‐maturity” emerged from the data. This concept sheds light on the entangled imbrications of maturity, competence, and success. Practices are regressed against performing‐maturity to reveal best contextualized practices.     

Closed-skew normality in stochastic frontiers with individual effects and long/short-run efficiency

This paper considers the estimation of Kumbhakar et al. (J Prod Anal. doi:10.1007/s11123-012-0303-1, 2012) (KLH) four random components stochastic frontier (SF) model using MLE techniques. We derive the log-likelihood function of the model using results from the closed-skew normal distribution. Our Monte Carlo analysis shows that MLE is more efficient and less biased than the multi-step KLH estimator. Moreover, we obtain closed-form expressions for the posterior expected values of the random effects, used to estimate short-run and long-run (in)efficiency as well as random-firm effects. The model is general enough to nest most of the currently used panel SF models; hence, its appropriateness can be tested. This is exemplified by analyzing empirical results from three different applications.     

Are Intellectual Property Rights Detrimental to Innovation?

Intellectual property rights are legal constraints that limit conditions of entry in industries where incumbents are innovators. The set of legal constraints is the same for all industries, and there is no consideration of the possibility that the externalities created by entry in a given industry may not necessarily be negative for the incumbent, or that the incumbent's R&D expenditures might actually be detrimental to new entrants. We show that one unique set of legal rules can foster innovation in some industries and be detrimental in others. Our model is illustrated by case studies from the Information and Communication Technologies industry.     

Subcontracting chain and workers’ participation in continuing vocational training: findings from the French,quantitative, linked employer–employee survey of training and career paths

This article discusses the correlation between cascading subcontracting and employees' participation in continuing vocational training. Based on a capability approach, it uses the French quantitative linked employer–employee survey on training and career paths (DEFIS) to question to what degree inter‐firm relations influence their employees’ training opportunities and processes. The results suggest cascading effects in training participation, considered from the angle of taking part both in training and training decision making. It addresses public policy issues arising from inequalities in employee participation with respect to the subcontracting relationship and thereby questions the liability of pure principal contractors.     

Does tick size influence price discovery? Evidence from the Toronto Stock Exchange

We investigate the price discovery role of an exchange‐traded fund and the futures contract for the same market index. We find that the fund predicts the index in the subperiod after but not in the subperiod before a substantial decrease in the minimum tick size. The futures predict the index in both subperiods. The results are consistent with the view that the factors leading to successful price discovery do not depend on zero investment, as in futures markets, but do depend on a small tick size. © 2003 Wiley Periodicals, Inc.
