The Interaction between a Most-Favored-Customer Clause and Price Dispersion: An Empirical Examination of the Medicaid Rebate Rules of 1990

This paper examines the effect of the MFC rules adopted by Medicaid on both price dispersion and price levels in the wholesale pharmaceutical market. Theory suggests that the regulations should reduce price dispersion and increase the average price for those products with a high initial level of price dispersion. Using data which can only measure some dimensions of price discrimination, I find that discrimination falls for products sold to hospitals, but not drugstores. Branded drugs facing generic competition have the most dispersion ex ante . Prices of these brands rise with dispersion at the implementation of the new rules. The last two results are consistent with Scott Morton (1997), where I look only at price changes due to the law. The results of this paper confirm that part of the mechanism of action for the price increase is the high level of price dispersion for some products combined with the MFC.     

Toward High Reliability Project Organizing in Safety‐Critical Projects

High reliability organizations claim to be special organizations that have consistently demonstrated safe performance in operating environments, which are simultaneously of high technical complexity, high consequence, and high tempo. This article argues that the literature on high reliability organizing, which emerged through studying day‐to‐day operations in the nuclear industry, air traffic control industry, and U.S. navy aircraft carriers, might hold important lessons for how the project management community can approach the management of safety‐critical projects—projects in which safety is of paramount importance. Its aim is to consider how high reliability organizing might be realized in these safety‐critical projects.     

The specificity of manufacturing in Marx's economic thought

Abstract

This article examines Marx's approach to manufacturing and the extent to which manufacturing could be considered to have a special place in Marx's economic thought, especially in relation to accumulation and growth. The important ‘progressive’ features of manufacturing that can be found in Marx's writings and which are discussed here include: division of labour; socialisation of labour; mechanisation; increasing returns to scale; learning-by-doing; technological advancement; and overall, superior potential for cumulative productivity increases. These insights anticipate some of the thinking around the specificity of manufacturing found in twentieth-century structuralist development economics and some heterodox schools of thought such as Kaldorian approaches. This article suggests an interpretation of Marx as having a two-dimensional conceptualisation of activity specificity, with not only sectoral but also ‘technological–organisational’ dimensions, where these two dimensions are not fully independent of each other.     

Earnings inequality and unemployment in South Africa

Unemployment and earnings inequality have moved together remarkably closely in South Africa in recent years. This article explores the relationship between unemployment and earnings inequality in South Africa, investigating the extent to which changes in unemployment can account for changes in earnings inequality. Static and dynamic decompositions of earnings inequality by employment status reveal the centrality of unemployment in accounting for the both level and trend of earnings inequality. The distribution of employment in the formal and informal sectors is found to be of lesser importance in explaining earnings inequality, as is wage dispersion within each of these categories. The findings point to the central importance of reducing unemployment in South Africa if the extremely high levels of inequality are to be reduced.     

Equality and diversity in the public services: moving forward on lesbian,gay and bisexual equality?

A key change for lesbian, gay and bisexual (LGB) people in the European Union has been the prohibition by the Employment Equality Directive (2000) of discrimination in employment on grounds of sexual orientation. This article focuses on the UK, which in 2003 introduced legislation making it unlawful to discriminate on these grounds. It explores the factors encouraging ‘good practice’ in sexual orientation equality work. It considers progress within the public services that have ‘pioneered’ sexual orientation equalities work, drawing on the views of LGB employees, management and trade union stakeholders. The recent legislation is considered to have provided a major impetus for change; however, an emerging ‘business case’ within the public service modernisation agenda is considered to have provided both opportunities and barriers to progress. A challenge for HR practitioners is getting organisational commitment to sexual orientation work, which is still perceived within organisations as a ‘sensitive’ area.     

On the export-led growth hypothesis for the little dragons: An empirical reinvestigation

The export-led growth hypothesis is tested using quarterly time series data for Hong Kong, Korea, and Taiwan and by constructing a vector autoregression (VAR) model. The Granger no-causality procedure developed by Toda and Yamamoto [1995] was applied to test the causal link between real export growth and real industrial output growth. Three distinct features in this paper stand out against earlier studies on the Little Dragon countries of Asia. First, going beyond the traditional two-variable relationship, a VAR model is built in the production function context to avoid a possible specification bias. Second, Riezman et al. [1996] are followed to test the export-led growth hypothesis while controlling for the growth of imports to avoid producing a spurious causality result. Third, the sensitivity of causality test results under different lag structures is tested along with the choice of optimal lags. In particular, the methodology developed by Toda and Yamamoto is expected to improve the standard F-statistics in the causality test process. The principal result from this research cannot offer support for the export-led growth hypothesis.
