Wage inequality between and within groups: trade-induced or skill-bias technical change? Alternative age models for the UK

According to recent econometric studies, technical progress is the main source of the increasing skill premium in the UK and the US. However, it is not yet clear if technical progress is skill-bias or sector-bias and, most importantly, if the use of foreign technology has a role to play. By using alternative AGE models for the UK economy, I show that both trade-induced sector-bias technical change and skill-bias technical change can explain the stylised facts of the UK economy: tertiarisation; deindustrialisation; openness to foreign markets; increased skill premium; rise in wage inequality within the skilled; and unskilled labour groups. However, the model with sector-bias technical change due to trade performs better, because it can also explain two other important stylised facts: the decline of the wage rate of unskilled workers; and the large increase of imported capital goods.     

The relationship between HRM avenues of political influence and perceived organizational performance

This article explores the relationship between the human resource management function's access to avenues of political influence and perceived organizational performance. We examine responses from 441 Australian senior HRM managers who participated in an online survey of a national HRM professional association. Drawing from political influence theory, we develop a model and related hypotheses to investigate the impact of opportunities for the HRM function to manage and control the shared meaning of HRM on perceived organizational performance. Although there was no evidence of a moderating effect of avenues of HRM political influence, CEO support and organizational support for HRM predicted perceived organizational performance. HRM representation on the board of directors appears to serve a symbolic function only. Theoretical and practical implications are discussed in response to the identified importance of CEO and organizational support. © 2007 Wiley Periodicals, Inc.     

Distribution-free test procedures in two-way layouts; a concept of rank-interaction

Summary  In this paper the concept of 'rank-interaction' is introduced and a distribution-free method for testing against the presence of 'rank-interaction' is suggested in the case of a two-way layout (classification) with m (> 1) observations per cell. Roughly speaking rank-interaction can be understood as the phenomenon at which the ranks of the levels of some relevant variable are different for different classes of the other factor. The exact null distribution of the test statistic has been computed in some cases. The asymptotic distribution under the null hypothesis has been derived. A test suggested by J.V. B radley in his book 'Distribution-free Statistical Tests' [2] is discussed. In the opinion of the authors it is doubtful whether the asymptotic distribution of the test statistic under the null hypothesis, as given by B radley , is correct. The test of B radley was intended to be sensitive to the presence of interactions defined in the usual way and hence not only to 'rank-interaction'. The same applies to methods proposed by some other authors. We claim that situations exist where one should test against rank-interaction and not against the usual more general alternative.     

School, images of the futures and social processes in classrooms

Futures studies express a deep concern for the negative effect school education has on young people's images of the future and their proactive attitude to the future. Here, images are regarded as cultural maps and the article attempts to outline a model of interaction in the classroom, which may be useful for understanding how school practices affect images.Given the cultural perspective on images, the analysis focuses on the social processes that organise the creation, negotiation, and distribution of cultural inventories in the classroom, including the meanings and meaningful expressions about future.

Whenever a culture is understood to be a collective phenomenon, it needs a sociology. When this sociology is left implicit, the danger is greater than it is a weak sociology.Ulf Hannerz

     

Die Versicherungsnachfrage von Unternehmen: Eine Empirische Untersuchung der Sachversicherungsnachfrage deutscher Unternehmen

This article presents the results of an empirical analysis regarding the corporate demand for insurance. As several studies before tested the theoretical arguments for the corporate motivation to purchase insurance, this article provides the fist empirical analysis focussing on the insurance demand of German corporations. The empirical evidence, found in the data of corporate clients of a German insurance company, supports the hypotheses regarding the relation between the demand for insurance and the size of the corporation, insolvency costs and real services of the insurer as well as the influence of the ownership structure of a stock corporation. Conflicting results were found regarding regulation.     

Corporate governance quality: Trends and real effects

This paper constructs a composite index of corporate governance quality, documents its evolution during the 1994–2003 period in selected emerging and developed economies, and assesses its impact on growth and productivity of the economy and its corporate sector. Our investigation yields three main findings. First, corporate governance quality in most countries has overall improved, although in varying degrees and with a few notable exceptions. Second, the data exhibit cross-country convergence in corporate governance quality with countries that score poorly initially catching up with countries with high corporate governance scores. Third, the impact of improvements in corporate governance quality on traditional measures of real economic activity—GDP growth, productivity growth, and the ratio of investment to GDP—is positive, significant and quantitatively relevant, and the growth effect is particularly pronounced for industries that are most dependent on external finance.     

Optimal public funding for research: a theoretical analysis

This article studies how a government should distribute funds among research institutions and how it should allocate them to basic and applied research. Institutions differ in reputation and efficiency and have an information advantage. The government should award funding for basic research to induce the most productive institutions to carry out more applied research than they would like. Institutions with better reputation a do more research than otherwise identical ones, and applied research is inefficiently concentrated in the most efficient high‐reputation institutions. The article provides theoretical support for a dual‐channel funding mechanism but not for full economic costing.     

The Impact of Economic Shocks in the Rest of the World on South Africa: Evidence from a Global VAR

The substantial change in South Africa’s trade patterns over the past two decades has affected the impact of economic shocks in major world economies on South Africa. To investigate the effect, we use a global vector autoregression (GVAR) model with time-varying trade weights to account for changing international trade linkages. We show that the long-term impact of a shock to Chinese GDP on South African GDP is much stronger in 2009 than in 1995, due to the substantial increase in South Africa’s trade with China since the mid-1990s. At the same time, the importance of the U.S. economy to South Africa diminished considerably. The results indicate one of the possible reasons why the recent global crisis did not affect South Africa as much as it affected developed economies. It also stresses the increased risk, to the South African and other economies, should China experience slower GDP growth.
