Keynesian economics in the twenty-first century1

The Keynesian theory as set out by Keynes embodied an Achilles heel which he himself half understood but chose to ignore. It is also ignored by “post-Keynesians” and “New Keynesians”. The trouble is not in the labour market but in the goods market, where The General Theory, at least up to Chapter 19, definitely assumes perfect competition. But on that assumption the possibility of a Keynesian recession requires that employers behave with highly inconsistent expectations. Once, however, the assumption of perfect competition in the goods market is replaced by imperfect competition or oligopoly, the Keynesian theory re-emerges not only as robust, but also totally relevant to the 21st century.     

Redistribution with Unobservable Bequests: A Case for Taxing Capital Income

This paper addresses the question of the optimal taxation of labour and interest income in an overlapping generations model with two unobservable characteristics, ability and inheritance. We assume realistically that saving can only be taxed anonymously, whereas the tax on labour earnings can be individualized and made non-linear. In such a setting, we show that a withholding tax on interest income along with a non-linear tax on labour income is desirable. The role of interest income taxation is to indirectly tax inherited wealth.

Competition in Communication Networks: Pricing and Regulation

By any measure, the communication sector is important. It isno surprise, then, that the communication sector has attractedthe attention of both policy-makers and economists. In thispaper, we argue that four characteristics of the networks thatdeliver communication services make this area of particularinterest. We analyse the implications of networks' cost structures;the strong complementarity between their components; the demand-sideexternalities that arise from consumption of their services;and the social obligations attached to them. Despite the attentionthat the communication sector has received, many aspects ofcompetition between networks are still poorly understood. Weidentify some of the key issues that will continue to troubleregulators and interest academics.     

Differences between Black and White South Africans in product failure attributions,anger and complaint behaviour

The purpose of this research is to extend an understanding of how Black and White South African consumers’ causal attributions for major household appliance performance failures impact on their anger and subsequent complaint behaviour. A survey was administered to Black and White South African consumers who were dissatisfied with the performance of a major household appliance item. Respondents resided in a major metropolitan area. The findings showed that, compared to Whites, the Black South Africans felt a low but significantly higher external locus of causality and lower control, and experienced a higher level of anger regarding product failure. The level of anger determined the decision to take complaint action, but racial group determined the type of action taken. Blacks complained more actively to retailers and engaged more in private complaint action than Whites. These findings may show that Black South Africans are developing a more individualistic orientation as consumers. Therefore, researchers should consider the effect of cultural swapping when researching consumer behaviour in multicultural countries. Implications for retailers in terms of complaint handling are indicated.     

‘Learning by importing’ in global value chains: upgrading and South–South strategies in the Ugandan pharmaceutical industry

Drawing on global value chain analysis, this article discusses the possibilities for upgrading in a domestically oriented import-dependent industry. The pharmaceutical industry in Uganda consists of a large number of importers, nine of which have upgraded into assembly and four a step further into manufacturing. The industry upgrades by a process of ‘learning by importing’. Although not engaged with global buyers, pharmaceutical producers in Uganda are tied into the global pharmaceutical value chain by international linkages with their suppliers, mainly in India, from whom they access technology and intermediates for production. Hence, this industry is based on South–South networks for production of low-value pharmaceutical products. With the globalisation of the pharmaceutical industry, an increasing number of global lead firms are ceasing to manufacture these products. This study illustrates an alternative form of industrialisation and upgrading that has not been adequately considered in the development of the African pharmaceutical industry.
