This article shows that mark‐ups are significantly higher in South African manufacturing industries than they are in corresponding industries worldwide. We test for the consequences of this low‐level of product market competition on productivity growth. The results of the paper are that high mark‐ups have a large negative impact on productivity growth in South African manufacturing industry. Our results are robust to three different data sources, two alternative measures of productivity growth, and three distinct measures of the mark‐up. Controlling for potential endogeneity of regressors does not eliminate the findings. 相似文献

It is generally accepted that moving from an unfunded to a funded social security system implies a welfare loss for the transition generation—that is, the generation that has to pay twice: first, saving for its own retirement and, second, contributing to the pensions of the then retired generation. This article shows that in a setting of endogenous growth with positive externality such a transition can be Pareto improving. But it argues also that social security reform is more a pretext than a requirement for internalizing such a positive externality. 相似文献

During the last decade economic literature explored the presence of and reasons for what became known as “the great moderation” in the US and other G7 countries. “The great moderation” describes the decrease in economic volatility experienced in many of the G7 countries. This paper finds that in South Africa volatility is also not constant (it even finds that there are autoregressive conditional heteroskedastic effects present) and that volatility also decreased, particularly since 1994. Following the literature, the paper explores several reasons for this decrease and finds that smaller shocks, better monetary policy and improvements in the financial sector that place less liquidity constraints on individuals and allow them to manage their debt better are some of the main reasons for the reduction in the volatility of the South African economy. The literature on the G7 also suggests that better inventory management contributed to the lower volatility. However, this seems not to be true for South Africa. 相似文献

It is shown that a differentiable market game remains generically inefficient when its strategic outcome function is perturbed smoothly. The proof is based on Thom's transversality theorem and removes any restriction regarding the dimension of the strategy spaces. A converse result is that almost all efficient market games that are competitive are characterized by Bertrand-like non-differentiabilities. Finally a synthesis between the Cournot-and-Bertrand-type approaches to Walrasian equilibrium, as recently developed in the literature, is suggested. 相似文献

In this paper we present some reflections on the development and state of research in marketing in Europe. After briefly putting European research in a historical perspective, we devote a major section to discussing the institutional setting in which research takes place. We believe that the institutional setting is a crucial determinant of research. We then discuss numumber of European research accomplishments. We essentially limit ourselves to marketing models and industrial marketing, our own major areas of interest. In the final section we list some challenges for the future and discuss how they could be turned into opportunities. 相似文献
