Supplier development and the relationship life-cycle

The mainstream view holds that over time buyer–supplier relationships evolve through a number of phases. As a consequence, supplier development as a buyer–supplier relationship management practice should also be adapted to the life-cycle phase. Supplier development activities matching the buyer–supplier relationship life-cycle phase will lead to more favorable performance improvements. However, prior studies have neglected the relationship life-cycle perspective. This empirical study shows how the length of the buyer–supplier relationship can be used to improve the explanatory power of models investigating the performance outcomes of supplier development activities. The results show that supplier development is more effective in mature as opposed to initial and declining life-cycles phases.     

Productivity-Wage Gaps Among Age Groups: Does the ICT Environment Matter?

This paper disentangles the age-productivity-wage nexus by estimating productivity and wage equations with longitudinal employer-employee panel data for Belgium. Results indicate that workers above 49 years are significantly less productive than their younger colleagues. Moreover, while relative productivities across age groups are not found to differ significantly between ICT and non ICT firms, the upward sloping age-wage profile appears to be somewhat steeper in ICT firms. Yet, whatever the ICT environment, findings show that young workers are paid below and older workers above their marginal productivity. This pattern is in line with the deferred payment model developed by Lazear (J Polit Econ 87:1261–1284, 1979).     

Are Occupations Paid What They are Worth? An Econometric Study of Occupational Wage Inequality and Productivity

Labour economists typically assume that pay differences between occupations can be explained with variations in productivity. The empirical evidence on the validity of this assumption is surprisingly thin and subject to various potential biases. The authors use matched employer-employee panel data from Belgium for the years 1999–2006 to examine occupational productivity-wage gaps. They find that occupations play distinct roles for remuneration and productivity: while the estimations indicate a significant upward-sloping occupational wage-profile, the hypothesis of a flat productivity-profile cannot be rejected. The corresponding pattern of over- and underpayment stands up to a series of robustness tests.     

Union absorptions in times of restructuring: the importance of attitude towards merger in predicting post‐merger attachment levels

Unions frequently restructure through merger, most often in the form of absorptions involving one bigger union absorbing a smaller one. However, the individual‐level effects of merger resulting in big amorphous organisations remain unclear. In this article, we highlight the role of the individual member in union absorptions, and investigate the relative importance of being a member of a large absorbing union or a small absorbed union, as well as the attitude of members towards merger in predicting post‐merger member attachment. The results from longitudinal data before and after absorption showed that members' attitude towards merger significantly predicted the members' attachment levels after absorption—this was, however, not the case for union commitment. We also uncovered a significant interaction indicating that the effect of members' attitude towards merger was more strongly related to perceptions of union support and instrumentality among members of the absorbed union.     

(Finding) Pathways out of homelessness: An engaged,trans-disciplinary collaborative in the City of Tshwane

ABSTRACT

Street homelessness in the City of Tshwane was brought to public attention in the winter of 2014. This led to a composite research project involving different constituencies, including homeless people, to reflect on ways of addressing street homelessness in the city. This article serves as a conceptual and epistemological introduction to this collaborative research project entitled Pathways Out of Homelessness. The article argues for the use of a broad working definition of street homelessness that allows for complexities of homelessness to emerge, in order to discern diverse and appropriate alternatives.     

The mover’s advantage: The superior performance of migrant scientists

Migrant scientists outperform domestic scientists. The result persists after instrumenting migration for reasons of work or study with migration in childhood to minimize the effect of selection. The results are consistent with theories of knowledge recombination and specialty matching.
