WAGNER'S LAW: AN ECONOMETRIC TEST FOR SOUTH AFRICA, 1960‐2006

The main objective for this paper is to test Wagner's law by analysing the causal relationships between real government expenditure and real income for South Africa for the period 1960‐2006. The paper tests the long‐run relationship between the two variables using the autoregressive distributive lag approach to cointegration suggested by Pesaran et al. We use the Granger non‐causality test procedure developed by Toda and Yamamoto, which uses a vector autoregression model to test for the causal link between the two. Evidence of cointegration is sufficient to establish a long‐run relationship between government expenditure and income. However, support for Wagner's law would require unidirectional causality from income to government expenditure. Therefore, cointegration should be seen as a necessary condition for Wagner's law, but not sufficient. This research does find a long‐run relationship between real per capita government expenditure and real per capita income. Results for the short‐run causality find bidirectional causality. On the basis of empirical results in this paper, one may tentatively conclude that Wagner's law finds no support in South Africa.     

French Cultural Decentralization and International Expansion.Towards a Geometrically Variable Interculturalism?

For a long time French local and regional authorities were largely excluded from debates on cultural policy, and even more so from international cultural exchanges. Their intervention in this second area, in its most conventional forms to its contemporary networks, occupies a special place in the present issues. Being sustained by large increases in local and national budgets for culture, such an evolution necessarily raised certain strategic issues and debates, which are discussed in the paper. The international element of local cultural policies has only recently appeared as a potential area for local strategy development. It can be seen as the result of the cultural generation of the 1980s, from the point of view of actors in both the public and professional domain. This paper examines the three following aspects: the forms taken by cultural decentralization in its main stages, through the conferral of negotiated powers; the modifications in centre-periphery relations brought about by this decentralization; and the emergence of an international exchange dynamic as a result of these first two processes.     

Ghana's agricultural food policy: Operation feed yourself

Prompted by food shortages, the newly ensconced Ghanaian military regime in 1972 initiated ‘Operation Feed Yourself’, a national programme directed at increased production of food crops. The authors attempt to determine how effective Operation Feed Yourself has been in attaining its goals. The bureaucracy which was set in place to implement the programme is assessed. Building on personal interviews conducted in Ghana with persons responsible for and affected by it, the authors discuss the successes and shortcomings of Operation Feed Yourself and suggest areas in which improvement might be made.     

Labour Demand Adjustment: Does Foreign Ownership Matter?

This paper examines whether multinationals differ in their employment adjustment from domestic companies, using a panel of 5,544 Belgian firms observed between 1998 and 2005. More precisely, we estimate labour adjustment costs by worker and firm types. We propose a new flexible specification that takes into account the role of firm size in adjustment costs. Our results indicate that adjusting white‐collar employment is around half as costly for multinational firms (MNFs) as for domestic firms of the same size. The remaining differential in adjustment costs between MNFs and domestic firms might result, among other things, from multinationals' stronger bargaining power.     

Aid,Aid Volatility and Sectoral Growth in Sub-Saharan Africa: Does Finance Matter?

This article examines the impact of aid and its volatility on sectoral growth by relying on panel dataset of 37 sub-Saharan African (SSA) countries for the period 1983–2014. Findings from the system-generalized methods of moments show that, while foreign aid significantly drives sectoral growth, aid volatility deteriorates sectoral value additions impacting heavily on non-tradable sectors with no apparent effect on the agricultural sector. The deleterious effect of aid volatility on sectoral value additions in SSA is weakened by a well-developed financial system with significant impact on the tradable sector. Evidently, development of domestic financial markets enhances aid effectiveness.     

Subcultural tensions in managing organisational culture: a study of an English Premier League football organisation

In this article, we explore subcultural interaction in the context of attempts by executives to control culture in the unusual organisational setting of football. We present evidence of five tension points in subcultural relations (togetherness or isolation, internal labour market, multiple identification and allegiances, individual and organisational requirements, and competition and cooperation). We examine how these tensions were induced and or exacerbated by the culture management efforts, as well as the ways in which the dynamics of change impacted on the objectives of executives. The article concludes with a discussion of the implications of the findings for theory and practice.     

Mean reversion and long memory in African stock market prices

We examine the behavior of stock market prices in several African countries by means of fractionally integrated techniques. In doing so, we can test for mean reversion in these markets. Our results can be summarized as follows: we cannot find evidence of mean reversion in any single market, and evidence of long memory returns (i.e., orders of integration above 1 in the logged stock prices) is obtained in the cases of Egypt and Nigeria, and, in a lesser extent in Tunisia, Morocco and Kenya. Permitting the existence of a structural change, the break dates take place in the earlier 2000s in the majority of the cases, and evidence of mean reversion seems to have taken place in the periods before the breaks in most of the countries. If we focus on the absolute and squared returns, evidence of long memory is obtained in Nigeria and Egypt. Thus, for these two countries, a long memory model incorporating positive fractional degrees of integration in both the level and the volatility process should be considered.
