Location of industry, market size, and imperfect international capital mobility

This paper examines the impact of imperfect international capital mobility on an industrial location when increasing returns are present. When the international capital mobility is perfect, agglomeration of manufacturing firms progresses with a decline in transportation costs of manufactured goods, and full-agglomeration in a large-market country is observed at low transportation costs. In contrast, when international capital mobility is imperfect, agglomeration in a large-market country progresses with capital trade integration. When the transportation costs of manufactured goods are low, all capital holders in two countries invest their capital into a home market.

Market size and seasonalities: The case of the UK investment trust industry

The particular characteristics of the UK mutual funds industry provide ideal ground for examining the pertinence of the ‘Small-size effect’ and the ‘tax-loss-selling’ hypothesis. The evidence indicates the presence of a modest-size premium for smaller investment trusts, but, rather surprisingly, size in general does not appear to be a determining factor of market performance. Moreover, in spite of some variation in the rates of return around the turn of the tax year, the evidence as a whole does not unambiguously support the tax-loss-selling hypothesis. However, there is ground to believe that the overall poor performance of the UK investment trust industry could be due to the tax regimen governing the industry's operations during the period 1965–80.     

Vertical integration and first-mover advantages in environmental taxes

This paper analyzes whether vertical integration between firms and suppliers encourages governments to behave as leaders in environmental policies. To study this issue, we consider transboundary pollution and two countries, with one firm in each country. We find that whether governments prefer to be leaders or followers in environmental taxes depends on two factors: whether firms are vertically integrated or not and the degree to which environmental pollution spills over to trading partners. When this overspill takes an intermediate value, taxes are set sequentially under vertical integration, but they are set simultaneously without it.

The causes of mergers: tests based on the gains to acquiring firms' shareholders and the size of premia

Despite the large number of event studies of mergers that have been undertaken, considerable disagreement still exists over whether mergers increase the value of the merging firms, and if so why. Most event studies measure the average returns to the acquired and acquiring companies' shareholders separately, and based on these averages conclude either that mergers increase wealth, or that they reduce it. From this the authors go on to claim support either for a hypothesis about how mergers increase efficiency, or for one that claims they do not. This paper develops a methodology that uses the distribution of gains and losses across the two samples of firms, and their relationship to one another to test four hypotheses about why mergers occur: (1) the market‐for‐corporate‐control hypothesis, (2) the synergy hypothesis, (3) the managerial discretion hypothesis, and (4) the hubris hypothesis. The hypotheses are tested with data for 168 mergers between large companies from 1978 through 1990. Considerable support is found for the managerial discretion and hubris hypotheses, and some support is found for the market‐for‐corporate‐control hypothesis. Little or no support is found for the hypothesis that mergers create synergies and that shareholders of both the acquiring and acquired firms share gains from these synergies.

Production Chains and Linkage Indicators

This paper uses a framework of production chains, which emerge from the vertical integration processes, in order to propose a general definition of linkage indicators. This definition is based on blocks of sectors and offers, among others, the following advantages. A reduction in the aggregation requirement, the resolution of the problems associated with the so-called distribution matrices, an easier analysis of the linkage components and, finally, the possibility to shed light on the links between Hypothetical Extraction Methods and sectoral analyses. Moreover, because of its general form, it helps to identify analogies between different types of indicators.

Relevance and advantages of using the item response theory

The item response theory (IRT) also known as latent trait theory, is used for the development, evaluation and administration of standardized measurements; it is widely used in the areas of psychology and education. This theory was developed and expanded for over 50 years and has contributed to the development of measurement scales of latent traits. This paper presents the basic and fundamental concepts of this IRT and a practical example of the construction of scales is proposed to illustrate the feasibility, advantages and validity of IRT through a known measurement, the height. The results obtained with the practical application of IRT confirm its effectiveness in the evaluation of latent traits.
