Dominance solvable approval voting games

This work provides necessary and sufficient conditions for the dominance solvability of approval voting games. Our conditions are very simple since they depend just on the number of possible winners when voters play weakly undominated strategies. If there are at most two possible winners, then the game is dominance‐solvable and the outcome coincides with the Condorcet winner. If every candidate is a possible winner, the game is not dominance‐solvable. If none of the previous conditions holds, then the game need not be dominance‐solvable, and the outcome need not coincide with the Condorcet winner.     

International trade and unionization: Evidence from India

We exploit exogenous variation in tariffs to examine the impact of import competition on unionization and union wages in a developing country. Using a combination of nationally representative household data (National Sample Survey Organization) and nationally representative industry‐level data (Annual Survey of Industries) from India, we find that net‐import industries that experienced larger cuts in tariffs also experienced larger declines in unionization. In addition, we find that these industries also experienced larger increases in union wages. These results are consistent with the predictions of an efficient bargaining framework that we extend to endogenize the union formation decision by allowing for a fixed cost of union formation. We also conduct a back‐of‐the‐envelope calculation to show that the total wage gains to unionized workers marginally exceed the total wage losses to deunionized workers.

Ethical Attitudes of Accounting Practitioners: Are Rank and Ethical Attitudes Related?

We address a previous finding in the business ethics literature in which accounting professionals in higher rank levels, i.e., “manager” or “partner” of auditing firms, appear to have lower moral reasoning ability than their junior counterparts. Prior investigations have relied upon a similar methodology for estimating ethical beliefs, namely testing “moral reasoning ability” using either the Moral Judgment Interview or Defining Issues Test. In the present study, we use a multiple vignettes approach to test for the existence of the inverse rank-ethical beliefs effect. With only 2 of the 30 vignettes resulting in both managers and partners being more accepting of the ethically charged behaviors, the results presented here using this alternative methodology are generally not supportive of the inverse rank-ethical beliefs phenomenon. We also use a multivariate analysis in order to control for demographic characteristics. Our results suggest that the most robust predictor of ethical attitudes among accounting practitioners is age, not rank within a firm.

Dynamic capabilities through continuous improvement infrastructure

We examine the content of continuous improvement strategies and identify infrastructure decision areas that are important for continuous improvement initiatives. We present a framework of infrastructure based on the idea that continuous improvement can serve as a dynamic capability when it includes a comprehensive organizational context. Further, we study continuous improvement initiatives in five companies to investigate the practices used by them in each of the decision areas of our framework. This research adds to the conceptual understanding of continuous improvement and results in grounded propositions about critical areas of infrastructure for continuous improvement.

Bringing science to market: commercializing from NIH SBIR awards

We offer empirical information on the correlates of commercialization activity for research projects funded through the US National Institutes of Health's (NIH's) Small Business Innovation Research (SBIR) award program. Based on this analysis we suggest possible recommendations for improving this aspect of the performance of NIH's SBIR program. Specifically, we estimate a model of the probability of commercialization as a function of the project's ability to attract additional developmental funding, along with other control variables. We find that additional developmental funding from non-SBIR federal sources and from own internal sources are important predictors of commercialization success, relatively more so than additional developmental funding from venture capitalists. We also find, among other things, that university involvement in the underlying research increases the probability of commercialization. Thus, these factors should be considered by NIH when making awards, if increased commercialization is an objective.
