Can a Wealthy Economy Gain from an EU Membership? Adjustment Costs and Long Term Welfare Effects of Full Integration—The Norwegian Case

We employ a large scale macroeconometric model to study adjustment problems and long term welfare effects of a Norwegian EU-membership. Accession costs depend significantly on the country's level of GDP, the size of its agricultural sector and tariff and VAT revenues as these elements determine the net membership contribution. Without the transfers, integrating the economy into EU generates a small welfare gain. This result is strongly affected by a long period with under-utilisation of resources. With the net contribution included, we identify a welfare loss. This is especially so if fiscal policy is changed to maintain the public sector budgetary balance.     

The effect of unemployment insurance on the riskiness of occupational choice

This paper examines the effect of unemployment insurance on the riskiness of occupational choice by postulating a model of job search in which job offers have two characteristics; their wage and their security of tenure. Two versions are considered: a general case in which the unemployment benefit is earnings-related, and a special case in which the benefit is of a flat-rate form. Of particular interest in the paper is the individual's desired trade-off between wage and security of tenure, and how this trade-off is affected by the type of insurance scheme in operation. Perhaps surprisingly, we find that an earnings-related scheme encourages risk-taking behaviour by the poor, and risk-avoiding behaviour by the rich; in contrast, a flat-rate scheme neither encourages nor discourages risk-taking.     

Mapping accessibility in Belgium: a tool for land-use and transport planning?

This paper compares the spatial structure of car accessibility to towns and to railway stations during peak and off-peak hours in Belgium for the country’s 2616 municipalities. A clustering method is applied. It is shown that in a highly urbanised country, the situation is far from being spatially equitable in terms of accessibility, and some areas are more favoured than others. Congestion increases spatial inequalities, differently according to absolute or relative measures of change. By means of examples, this paper shows that even simple accessibility indicators could be useful to support decisions taken by planners and politicians (e.g. as regards the development of residential, industrial and business park areas). Maps indicate the spatial inequalities in terms of accessibility to urban centres and transport nodes, and the impact of congestion on these inequalities. The absolute and relative time losses due to congestion affect different areas in different ways. The location of new developments further increases the congestion problem and the spatial disparities. This paper also insists on the caution that should be adopted when measuring and interpreting “accessibility”, its measurements, its inputs, its temporal changes in absolute and relative terms as well as the need for spatially disaggregated data.     

Managing international supply: The balance between total costs and customer service

Many trading companies have taken a global approach to their supply markets, sourcing from low-cost foreign countries in order to achieve cost reductions. There remains, however, a lack of evidence that sourcing internationally actually leads to improved economic performance. This can be explained by two key challenges in terms of how to achieve a balance between: (1) purchasing and logistics costs, and (2) customer service. The purpose of this paper is to examine the organisation and management of international supply from a total cost perspective, taking into account both purchasing and logistics costs, as well as customer service and agility. Previous research into a number of Norwegian companies that have sourced from China has identified four configurations for managing international supply. This paper utilises the supply management literature and an example of a Norwegian retail and wholesale company to analyse and discuss these configurations and their effects on total costs and customer service. The paper's theoretical contribution is the conceptualisation of a total cost perspective on international supply management and the discussion of such costs in relation to customer service. This contribution may, in turn, aid companies that source from foreign, low-cost countries.     

The Dynamics of Self-Esteem and Physical Self: Between Preservation and Adaptation

The aim of this study was to model and characterize the psychologicalprocesses that underlie the dynamics of global self-esteem and physicalself over time. Twice a day for 228 consecutive days, seven participantscompleted a short inventory (PSI-6, Ninot et al., 2001) measuring sixsubjective dimensions: global self-esteem, physical self-worth, physicalcondition, sport competence, physical strength, and attractive body.Each series was modeled by means of ARIMA procedures. The resultsshowed that a simple moving average model provided a satisfactoryaccount for the dynamics of all series. This model suggests that acombination of two opposite processes underlies the dynamics ofself-concept: preservation, which tends to restore the previousvalue after a disturbance, and adaptation, which tends to inflectthe series in the direction of the perturbation.     

The Valuation of Structured Products: Empirical Findings for the Swiss Market

This article analyses the valuation of 192 structured products without a capital guarantee. In contrast to similar studies, this investigation takes in both the primary and the secondary market. Its central element is a comparison of the implied volatilities of the options contained in the structured products with those of comparable EUREX options. Generally speaking, the results may well come as a surprise both concerning the scale of the phenomenon detected and its significance. Taken as a whole, the results provide grounds for assuming that certain inefficiencies exist on the Swiss market for structured products and that lead managers manage to exploit their quasi-monopolistic position in a rational manner.
