Future fall-out from the genetic revolution

It is argued that the genetic engineering revolution now under way is fundamentally different from other industrial revolutions in that humans are developing the technological power to change themselves. This article begins with an overview of the technology involved, discusses the Human Genome Initiative (HGI) programme and gene therapy research, and then uses several possible future scenarios to discuss potential legal and ethical issues.

Airline networks as joint goods: Implications for competition policy

This article derives a model of airline services as joint goods. Using this model, the article shows how the existence of higher fares in certain hub routes may imply the market has generated a solution to the problem of covering joint costs by having a larger proportion of those costs come from hub routes, rather than the existence of any general market failure. The model is then used to make recommendations for competition policy.     

Operational Research and the environment

The discipline of Operational Research (OR) is primarily concerned with improving the effectiveness and efficiency of decision processes. These processes take place everywhere in society: industry, banking, agriculture, government, politics. Frequent use of mathematical optimization models is typical of OR. Since the early '80s these models are increasingly packaged in a user-friendly way, as Decision Support Systems. In the following we will illustrate how OR can be used to describe and solve a number of environmental problems.     

Policies for economic growth

Summary The old growth theory of the 1950s led to certain conclusions about the sorts of economic policies that would promote economic growth, and also about their limitations. The new growth theory of the 1980s makes much stronger assumptions and leads to correspondingly stronger conclusions about the scope of growth-promoting policy. This article argues that: (1) empirical work so far has neither confirmed nor denied the strong assumptions underlying the new theory; (2) the theory is worth pursuing because of its intrinsic interest and the possibilities it opens up; (3) whatever the final verdict on the new theory, both theory and evidence support the belief that significant long-run gains, even if not permanent changes in the growth rate, can be achieved by increased investment in the broadest sense, including human capital, technological knowledge, and industrial plant and equipment.Fifth Tinbergen Lecture delivered on October 4, 1991, in Amersfoort for the Royal Netherlands Economic Association     

Price as a signal of quality: Canada in the international context

Studies have shown that price is very poorly correlated with quality. This paper discusses the methodological criticisms of the earlier work, concluding that the original results remain robust. Examination of 91 sets of Canadian products containing 1020 items reinforces the conclusions of earlier work for the United States and Japan. These international studies contradict the conventional wisdom that price is an adequate signal of quality. We also test the hypotheses that price is a better signal of quality (a) after product tests have been published, and (b) for higher priced items which presumably justify larger investments in search. Canadian data do not support either hypothesis. Some theoretical explanations are outlined and a conclusion briefly presents implications for policy.

Der Preis als Qualitätsindikator: Kanadische und internationale Befunde

Zusammenfassung Zahlreiche Untersuchungsergebnisse haben gezeigt, daß Preis und Qualität in einem nur sehr dürftigen Zusammenhang stehen. Diese Befunde sind unter methodischem Gesichtspunkt kritisiert worden, der vorliegende Beitrag versucht jedoch zu zeigen, daß die Befunde robust sind und der Kritik standhalten können. Eine Untersuchung der Autoren anhand von 91 kanadischen Warentests mit 1,020 Artikeln bestätigt darüberhinaus die früheren Ergebnisse aus den Vereinigten Staaten und Japan. Insgesamt widersprechen diese internationalen Untersuchungen der herkömmlichen Ansicht, daß der Preis eines Gutes ein angemessener Qualitätsindikator sei.Darüber hinaus prüft die Studie der Autoren die Hypothese, daß der Preis ein besserer Qualitätsindikator ist, (a) nachdem Warentests durchgeführt und die Ergebnisse publiziert wurden, und (b) wenn es sich um teurere Produkte handelt, die vermutlich einen höheren Suchaufwand rechtfertigen. Beide Hypothesen werden durch kanadische Daten nicht gestützt. Abschließend werden einige verbraucherpolitische Implikationen dieser Befunde behandelt.The authors are grateful to referees for important assistance.

Force and Influence in Content Analysis: The Production of New Social Knowledge

We examine the two traditions of content analysis: the first in which one substitutes words of a text with categories, and the second in which one looks for clusters of words that may refer to a theme. In the first tradition, preexisting dictionary categories give meaning to the words; in the second, meaning comes after the fact. Preexisting dictionary categories (the substitution model) are calibrated instruments applied within experimental designs that leave no space for doubt; meanwhile, the ability of the correlational model to conjure up complex themes from fragments of a text yields no unique solution. These differences have bearings on the production of new social knowledge. We expound on the epistemological foundations of the two traditions of interpretation and draw from them decision rules upon which one may rely for choosing among appropriate content-analytic tactics. Two reasons make this essay timely and critical: (1) the increasing variety of new content-analyticsoftware for particular purposes and (2) the almost exclusive focusing on software and technology at the expense of adjusting the choice of the software to the nature of the text. Two studies, one in historiometry, the other in autobiography, illustrate the liabilities and benefits of the two models of content analysis.     

Integration of collective bargaining and formal worker participation processes: Boon or barrier to worker rights?

Many employers are extending workplace rights by allowing for more employee voice in decision making. Numerous unionized organizations have established formal worker participation processes to help achieve this end and to improve organizational performance. Based largely on theory, such processes are normally designed to operate independently from the bargaining process. The purpose of this study was to examine the relationship between participation and bargaining processes, and the effect of this relationship on workplace satisfaction. A total of 712 Midwest union officials were surveyed, and the results indicate that the processes tend to become integrated in the workplace. Further, union officials' workplace satisfaction was greater where formal worker participation is institutionalized within the bargaining process.
