The author develops a bilateral Nash bargaining model under value uncertainty and private/asymmetric information, combining ideas from axiomatic and strategic bargaining theory. The solution to the model leads organically to a two-tier stochastic frontier (2TSF) setup with intra-error dependence. The author presents two different statistical specifications to estimate the model, one that accounts for regressor endogeneity using copulas, the other able to identify separately the bargaining power from the private information effects at the individual level. An empirical application using a matched employer–employee data set (MEEDS) from Zambia and a second using another one from Ghana showcase the applied potential of the approach.

Competitiveness is an individual difference variable that incorporates factors generally associated with the desire to excel in comparison to others and the enjoyment of competition. There is still much debate on whether it is helpful or harmful, which may stem from the scattered ways in which it is studied. Thereby, this study aims to properly synthesize the literature concerning the prevailing correlates, underlying theory and frequent applications of competitiveness and to set forth an outline of domains in need of further research and exploration.

The authors do so by using two methods of analysis on a representative sample of 546 peer-reviewed publications.

The authors find that competitiveness research has and will continue to grow expeditiously, but its complexity and cloudiness have not yet been attenuated.

The study uncovers opportunities for pertinent future research on competitiveness to grow more productively and collaboratively by highlighting salient works and identifying the fragmentations that have led the literature into a state of disarray.
