Stabilisation of the monetary system

The devaluation of the British Pound and the most speculation in gold and the dollar have lead to a hectic activity on the part of the monetary authorities in the industrial countries of the West. It is unlikely that anybody should have regarded the splitting up of the gold market—necessary though it was as a counter-measure—as a panacea which would prove efficacious in the long run. At the meeting in Stockholm of the Club of Ten the attempt was therefore made to parry the diminshing importance of gold within the monetary system by a speedier activation of the Special Drawing Rights—“the paper gold”. This constituted without doubt a decisive step towards rationalising and stabilising the international monetary system.     

Grazing into the future: Policy making for South African communal rangelands

This article reports on a symposium held at Fort Hare University in July 1998. Its objective was to assess the current state of knowledge on communal rangelands and identify issues important for policy making. This was done in the light of concerns about recent policy reform. Uncontrolled access to resources and the lack of services were identified as the main constraints on socio‐economic development in the communal rangelands, and inadequate forage during the dry season was recognised as a general constraint on livestock production, irrespective of mean annual rainfall. Government policies must recognise these issues and the social and ecological heterogeneity of communal rangelands in South Africa. The conclusion with the most far‐reaching implications, however, was that degradation has occurred in some, but not all, communal rangelands and is most likely to occur in arid areas. This finding is in direct contrast to the current base for agricultural policies in South Africa, which assumes that livestock have little impact on rangelands.     

On the relationship between cost and service models for general inventory systems

In this paper, we present a systematic overview of possible relations between cost and service models for fairly general single- and multi-stage inventory systems. In particular, we relate various types of penalty costs in pure cost models to equivalent types of service measures in service models. We show how an optimal policy for a service model may be obtained from cost-optimal policies in a related pure cost model. Pure cost models have been studied extensively in the literature. By our results it seems possible to transform many of the known optimal solutions for pure cost models to service models, which are more appropriate from a practical point of view. A number of examples are discussed to show the generality and the possibly far reaching consequences of the results.     

Economic Impacts of Inbound Tourism under Different Assumptions Regarding the Macroeconomy

On what is taken to be the 'Standard View', increased tourism expenditure from inbound markets has direct, indirect and induced effects on a host destination, leading to increased production, income and employment. Strong links between tourism and other sectors of business reduce import leakages from tourism expenditure thereby enhancing the multiplier effects of the injected expenditure on domestic output, value added and employment. The usual technique for analysing these effects is input-output analysis. This paper argues that economy-wide effects must be taken into account in determining the impacts of increased tourism expenditure on a destination, and that the 'Standard View' is superficial and very often misleading. An expanding tourism industry tends to 'crowd out' other sectors of economic activity, reducing the demand for traditional exports and import competing industries. The extent of these 'crowding out' effects depends, in turn, on the workings of labour markets, changes in prices and the real exchange rate, and the macroeconomic policy context. It is argued that these mechanisms can only properly be taken into account using Computable General Equilibrium (CGE) models rather than input-output modelling. The paper then looks at applications of CGE modelling to tourism growth in both nations and regions, classifying the various studies according to assumptions made about labour markets and government policies. The discussion has relevance for estimating the economic contribution of tourism in all destinations. The paper concludes with some observations regarding the use of CGE modelling in tourism contexts internationally and issues for further research.     

Product quality selection: Contractual agreements and supplier competition in an assemble-to-order environment

We consider a multi-supplier, single-manufacturer supply chain where each supplier sells a different component at varying quality levels. The manufacturer has to decide on which quality level to choose for each component, trading-off the total cost and total quality. Each supplier decides on a price per unit quality level for its component. We characterize the strategic interaction among the suppliers and analyze the inefficiencies. We find that the inefficiencies due to such quality competition can be quite significant. We then propose and analyze several mechanisms, such as quality-price schedules and revenue sharing, that restore efficiency.     

Is Busy Really Busy? Board Governance Revisited

We investigate the relationship between firm governance and the board's position in the social network of directors. Using a sample of 133 German firms over the four‐year period from 2003 to 2006, we find that firms with intensely connected supervisory boards are (1) associated with lower firm performance, and (2) pay their executives significantly more. We interpret these results as evidence of poor monitoring in firms with directors who are more embedded in the social network. In both cases, simple measures for busy directors that were used by other studies in the past fail to show any significant pattern. The findings suggest that the quality and structural position of additional board seats may play a bigger role than simply the number of board appointments.
