The expectation of products of quadratic forms in normal variables: the practice

Summary  A table is presented to simplify the computation of the expectation of a product of quadratic forms in normal variables. Some peculiarities of the table are discussed.     

Regional Industrial Renewal: The Growth of 'Antenna Technology' in West Sweden

The article analyses how a technical knowledge field ('antenna technology') is developed and exploited in a region (West Sweden). To identify regional actors, the paper outlines a way of delineating a technical knowledge field and its changes over time. Drawing on this, an historical account is given of the international and the regional development, focusing on the changing and expanding nature of industries and markets (from military to civilian applications) and technologies. The paper emphasizes the long regional history, providing experience, which together with a number of diversifications, has given regional actors a platform from which to exploit the growing economic utility of the technical knowledge. It is also shown why some applications have not been exploited in the region.     

The Geography and Concentration of Authorship in the Top Five: Implications For European Economics

We study to what degree authors who publish in the five most prestigious journals in economics have previously published there and in which world region they are based. Although still high, the concentration of United States‐based and previously published top‐five authors has decreased. This trend is driven by increased co‐authorship between USA and non‐USA scholars and between scholars with and without previous top‐five articles. Only around 5% of all articles each year are written solely by first‐time authors from outside the United States, and this share has not increased since the mid‐1990s. Against this background, we argue that European institutions should be wary of putting too much emphasis on publishing in these five journals. Both the advancement and diversity of the economics discipline may otherwise suffer.     

Students’ attitudes toward technology: exploring the relationship among affective,cognitive and behavioral components of the attitude construct

Attracting private sector participation in infrastructure investment: the UK case

This article examines the potential for private sector organizations to contribute to public sector innovation. Specifically, the study explores how partnering with the private sector can go beyond delivery and extend to development of new services and new markets. The term ‘commercialization partnership’ is coined for such partnerships and the article describes an exploratory investigation of this emerging form of innovation.     

Corruption in public service delivery: An experimental analysis

To improve our understanding of corruption in service delivery, we use a newly designed game that allows us to investigate the effects of the institutional environment on the behavior of service providers and their monitors. We focus on the effect of four different factors: whether monitors are accountable to the service recipients, the degree of observability of service providers’ effort, the providers’ wages and the providers’ professional norms. In accordance with theory, we find that service providers perform better when monitors are elected by service recipients and when their effort is more easily observed. However, there is only weak evidence that service providers perform better when paid more. Monitors are more vigilant when elected and when service providers are paid more. Playing the game with Ethiopian nursing students, we also find that those with greater exposure to the Ethiopian public health sector perform less well, either as provider or as monitor, when the experiment is framed as a public health provision scenario, suggesting that experience and norms affect behavior.     

Welfare Capitalism in Post-Industrial Times: Trilemma or Power Over Rents?

The structure of ‘post-industrial’ economies is widely held to be problematic for welfare capitalism, because of inherent limits to productivity growth in services compared to manufacturing. The so-called post-industrial trilemma is suggested to allow only two of relative earnings equality, high levels of employment and fiscal balance, and has resulted in the widespread policy belief that greater earnings inequality and welfare state retrenchment are unavoidable. This article challenges the micro foundations of this understanding, that the production of economic value is technologically determined by the physical properties inherent in goods and services. In contrast, we argue theoretically, and demonstrate empirically, that production, allocation and distribution are contingent processes better conceived in terms of ‘power over rents’ with associated externalities between sectors. Our analysis suggests that the post-industrial trilemma thesis may have unduly distracted research from the potential for redistributive politics to achieve sustainable levels of productivity growth, fiscal balance and higher levels of earnings equality.     

Son Preference,Number of Children,Education and Occupational Choice in Rural Nepal

A unique family survey was conducted in Nepal to investigate the economic consequences of having a first‐born girl. Women have more children, but we find no causal effect of number of children on economic outcomes, but independently of the number of children there is a positive effect on boys’ education of having a first‐born sister, who presumably takes care of household work so the boys can focus on school. This indicates a stronger son preference in Nepal than that found in studies from neighboring countries.     

Institutional Effects on the Evolution of the Size Distribution of Firms

In this paper it is argued that the size distribution of firms may largely be determined by institutional factors. This hypothesis is tested in an exploratory fashion by studying the evolution of the size distribution of firms over time in Sweden for a period spanning from the late 1960s to the early 1990s. The data used are divided into finer size classes compared to most previous studies. This gives more scope for investigating the impact of institutions. Moreover, we use a unique data set, starting in 1984, to take account of corporate groups and government ownership. The analysis shows a poor development for intermediate-sized (10–199 employees) firms. This is likely to reflect the existence of a threshold that many firms are either unwilling or unable to cross. The analysis of the institutions and rules of the game determining the entrepreneurial and business conditions in Sweden indicate that the conditions have been unfavorable for small firms, and hence that too few small firms have managed to grow out of the smallest size classes. The conclusion is supported by an international comparison of the number of firms in different size classes. Data indicate that Sweden has fewer small (10–99 employees), and more large (500+) firms per capita than other European countries.     

Reviewing Proposals for a World Environmental Organisation

Since the Earth Summit in Rio 1992, several calls have been made for a world environmental organisation (WEO), and only during the last year, in the run‐up to Rio+10, five more have been added. In total, we have found 17 proposals for a WEO. We review, compare, and briefly discuss rationales, models, tasks, organisational set‐up, relations to multilateral environmental agreements (MEAs) and organisations such as UNEP and the WTO, as well as the role of principles, compliance and the interest of developing countries. We conclude that a majority of proposers is in favour of an autonomous coordinating agency, that is, a medium level of integration. Frequently the WTO is mentioned as a precursor agency on which a WEO should be based. We question the effectiveness of a ‘WTO for the environment’ and suggest that other models ought to be considered.
