Price Discrimination in Input Markets: Downstream Entry and Efficiency

The extant theory on price discrimination in input markets takes the structure of the downstream industry as exogenously given. This paper endogenizes the structure of the downstream industry and examines the effects of permitting third‐degree price discrimination on market structure and welfare. We identify situations where permitting price discrimination leads to either higher or lower wholesale prices for all downstream firms. These findings are driven by upstream profits being discontinuous due to costly entry. Moreover, permitting price discrimination fosters entry which often improves welfare. Nevertheless, entry can also reduce welfare because it may lead to a severe inefficiency in production.     

Latin America’s external indebtedness

Latin America’s foreign debts have been mounting fast in the last ten years. The following article shows that it would nevertheless be wrong to suggest that Latin America has generally run up excessive debts.     

How Useful Are the Strategic Tools We Teach in Business Schools?

Strategic tools are indispensible for business and competitive analysis. Yet we know very little about managers' internal logic as they put these tools into practical use. We situate our study in a business school context using action learning prior to the manifestation of practice to complement our understanding of practice. Using Personal Construct Theory and Repertory Grids, our mid‐range theorizing showed that, contrary to current thinking about strategic tools, managers think in dualities (often paradoxically) and have a preference for multiple‐tools‐in‐use, tools that provide different perspectives, peripheral vision, connected thinking, simultaneously help differentiate and integrate complex issues, and guide the thinking process. These findings are important for designing better tools and the nurturing of critical managerial competencies needed for a complicated world. Our study's focus also has wider implications for scholars as we see our own material evaluated by those who will put these lessons into practice.     

Same Same But Different: Dialects and Trade

Language is a strong and robust determinant of international trade patterns: Countries sharing a common language trade significantly more with each other than countries using different languages, holding other factors constant. In this article we present the first analysis of the effect of language on trade in an intra‐national context. Analyzing unique data for a single‐language country, Germany, we find that similarities in the local dialect have a significantly positive impact on regional trade. We interpret this finding as evidence for the trade‐promoting effect of culture, because linguistic similarities likely reflect cultural ties across regions, rather than lower costs of communication or similar institutions.     

Rating Agencies – An Experimental Analysis of Their Remuneration Model

Does it matter who pays for ratings? Yes, but not for the rating agencies’ behavior. These are the findings of our experiment where we analyze the effect of the remuneration model of rating agencies on their assessments as well as on investors’ and issuers’ behavior. First, we find that rating agencies’ assessments are comparable whether the agency is (partially) paid by issuers, investors or solely by the experimenter. Issuers, on the other hand, more often do not return investor's trust when they or investors pay for ratings. Further, investors more often act according to the agencies’ recommendations when they have to pay for this information.

The Multi-Fibre Arrangement—A hydra of protectionism?

Talks are at present in progress in Geneva among 51 industrialised and developing countries on a renewal of the Multi-Fibre Arrangement (MFA) which expires at the end of 1981. The preliminaries of the negotiations have already revealed the existence of massive conflicts of interest not only between the industrialised countries on the one hand and the developing countries on the other but also within the two groups. The talks are moreover overshadowed by threats from individual industrialised countries to resort to unilateral protectionist measures unless a result satisfactory to them is achieved. This situation is the more explosive as the outcome of the negotiations is regarded worldwide as a “landmark for future trade relations between developing countries and industrialised countries”. What is it all about?     

Budgetdefizite und Finanzierungsüberschüsse

In den Stabilit?ts- und Wachstumspakt ist die 3%-Defizitgrenze für den Staatshaushalt vor allem deshalb eingebaut worden, weil eine zu hohe Beanspruchung des gemeinsamen Kapitalmarktes der Eurozone verhindert werden sollte. Welche Erkenntnisse lassen sich zur tats?chlichen Inanspruchnahme des Kapitalmarktes aus den Finanzierungssalden der Volkswirtschaftlichen Gesamtrechnung gewinnen? Wie ist bei solch einer Betrachtung das Argument der Generationengerechtigkeit zu beurteilen? Welche Folgen h?tte gegenw?rtig eine Haushaltskonsolidierung?     

Verbraucherpolitische Konzeptionen und Programme in der Bundesrepublik Deutschland

Zusammenfassung Die Notwendigkeit einer expliziten Verbraucherpolitik ist in der Bundesrepublik Deutschland in den letzten Jahren zunehmend anerkannt worden. Dies dokumentiert sich zum einen in einigen Ansätzen zur Institutionalisierung der Verbraucherpolitik, zum anderen in einer programmatischen Diskussion, an der inzwischen die wichtigsten gesellschaftlich relevanten Gruppen teilnehmen. Analysiert und vergleicht man die verbraucherpolitischen Vorhaben amtlicher Stellen sowie die von Arbeitgeberverbänden, Gewerkschaften und politischen Parteien entwickelten Konzeptionen, so zeigt sich ein uniformes Denkschema, das dem Paradigma Markt und Wettbewerb verhaftet ist. Unterschiede offenbaren sich lediglich in den jeweils präferierten Maßnahmen. Alle Konzeptionen folgen — wenn auch mit unterschiedlicher Gewichtung — den beiden handlungsanleitenden Argumentationsschemata »Ergänzung der Wettbewerbspolitik durch Verbraucherschutz und -information« sowie »Gegenmachtbildung und Interessenvertretung«. Der Gedanke an direktere Kommunikationsformen sowie an eine frühzeitige Einflußnahme der Konsumenten auf das Güterangebot findet sich in keinem der Programme.

Conceptions of consumer policy in the Federal Republic of Germany

The necessity for an explicit public consumer policy has found increased acceptance during the last couple of years. This is reflected both in attempts to institutionalize consumer policy and in a programmatic discussion in which many relevant social groups are participating. The analysis of consumer oriented plans and models of governmental agencies, employers' associations, trade unions, and political parties reveals uniform thought, rooted in the paradigm of market and competition. Differences can be detected only in the recommended measures. Basically all concepts fall under one of the following categories of argumentation: Competition policy needs completion by consumer protection and consumer information or There is a need for consumer countervailing power and consumer lobbyism. The existing plans are characterized by mere auxiliary means to stimulate consumers' reactions. The considerations of a direct communication between producers and consumers and of an early influence by consumers on manufacturers' product decisions are, however, not included in any of the programmes.
