On technical analysis

Technical analysis, or the use of past prices to infer privateinformation, has value in a model in which prices are not fullyrevealing and traders have rational conjectures about the relationbetween prices and signals. A two-period dynamic model of equilibriumis used to demonstrate that rational investors use historicalprices in forming their demands and to illustrate the sensitivityof the value of technical analysis to changes in the valuesof the exogenous parameters.     

The evolution of competition in U.S. manufacturing

Although four-digit concentration ratios remained roughly constant in the quarter century between 1958 and 1982, they declined significantly when adjusted for imports. The empirical analysis in this paper shows that changes in both types of four-digit concentration ratios were related to the initial level of industrial concentration, barriers to entry, market growth, and to a set of adjustment variables reflecting an interaction of imports and particular structural aspects of the industry. Speculations about the future of competition in the United States are based on the regression equations explaining changes in concentration.I would like to thank John Caskey, Ellen Magenheim, Lee Perlman, Zora Pryor, F. M. Scherer, and participants of the Swarthmore Economics Department's Summer Brown Bag Lunch for comments on an earlier draft. I am also grateful to Chang-Tai Hsieh, who served as a research assistant in the initial stages of research, to the Swarthmore College Faculty Research Fund for financing, to the Brookings Institution where this essay was completed, and to Richard Caves and Lawrence Katz for supplying data classified by four-digit industries to me. Of course, only I am responsible for my conclusions and errors.     

High and low levels of organizational adaptation: An empirical analysis of strategy,structure, and performance

In this study, we have examined high and low levels of organizational adaptation to environmental change by analyzing strategy, structure, and performance relationships. Our results indicate that organizations with particular levels of adaptation tend to have specific strategy-structure arrangements which yield certain performance results. Organizations with an optimum strategy-structure match tend to have higher performances. Implications for future research in organizational adaptation are discussed.     

The Research Assessment Exercise, the state and the dominance of mainstream economics in British universities

In previous research on the impact of the Research AssessmentExercise on heterodox economics and heterodox economists inthe UK, the author concluded that reliance on Diamond List journalsto rank departments would drive economic departments to discriminatepositively in terms of their hiring, promotion and researchstrategies in favour of mainstream economists and their research,in order to maintain or improve their ranking. As a consequence,the author predicted there would be no or only a token presenceof heterodox economists in an increasing number of departments.Whether the conclusions still hold and the predictions materialiseis the subject of the paper.     

The 'New Class': Analysis of the Concept, the Hypothesis and the Idea as a Research Tool

A bstract . The concept of the 'New Class' often is invoked to explain not only why the capitalist countries of the West are drifting leftwards into socialism but also why socialist nations of East Europe have totalitarian governments, tolerate gross economic inefficiencies, and exploit their workers. Certain critical issues underlying such an approach that are relevant to political economists , especially those interested in the changing boundary between the public and private sectors of the economy , are examined. The concept is found to rely on hypotheses which are not (easily) testable and the argument for its existence to be based on premises that are dubious. Special attention is given to hypotheses in public finance employing the concept in an attempt to explain increasing public expenditures ; these are found wanting.     

Culture and Economic Systems

A bstract .   Applying a cluster analysis to the results of the World Value Study, this article shows that the OECD nations have five distinct patterns of cultural characteristics. Moreover, these five cultural systems are almost the same as a classification of economic systems that have been derived from a cluster analysis of their economic institutions. A comparison of the cultural characteristics of East and West Germany suggests that the economic system has relatively little influence on the cultural systems. Instead, in a democracy, where the economic system is not imposed by force, the cultural characteristics are more likely to determine the economic system, rather than the reverse.     

Medicines transparency at the European Medicines Agency (EMA) in the new information age: the perspectives of patients

The concept of transparency has gained widespread appeal in the European pharmaceutical domain, not least at the European Medicines Agency (EMA). Agency policies have two main objectives: (1) to enable the reuse of data (e.g. clinical study reports) and (2) to empower patients to directly and indirectly make more informed decisions on medicines. Past research has almost exclusively focused on the perspectives of external researchers intending to reanalyse data made publically available. Few studies, however, have explored what can be learnt from the perspectives of other actors (e.g. health care professionals, patients, the regulators themselves, industry and others). This empirical study explores the EMA’s transparency policies from the perspectives of patients. After presenting the results of a survey (N = 1010) with a sample of individuals diagnosed with five specific medical conditions (HIV/AIDS, multiple sclerosis, rheumatoid arthritis, osteoporosis and idiopathic pulmonary fibrosis) from four EU countries (Germany, Spain, France and the UK), the authors argue that EMA’s transparency policies do not adequately address the real-world complexities of communicating with patients. In turn, the paper concludes that the perspective of patients provides an essential contribution to understanding the full net effects (positive, negative and/or limited) of EMA’s transparency policies.     

Nonparametric tests of collectively rational consumption behavior: An integer programming procedure

We present an IP-based nonparametric (revealed preference) testing procedure for rational consumption behavior in terms of a general collective model, which includes consumption externalities and public consumption. An empirical application to data drawn from the Russia Longitudinal Monitoring Survey (RLMS) demonstrates the practical usefulness of the procedure. Finally, we present extensions of the testing procedure to evaluate the goodness-of-fit (accounting for optimization error as well as measurement error) of the collective model subject to testing.
