Parametric Portfolio Policies in the Surplus Consumption Ratio

The surplus consumption ratio plays a central role as a state variable in successful attempts to explain the time series properties of stock and bond prices with consumption‐based asset pricing models. In this paper, optimal portfolio policies for a strategic investor who maximizes the conditionally expected utility of terminal wealth are parameterized as a polynomial in the surplus consumption ratio. Optimal portfolio policies are estimated using a method of moments estimator based on Euler equations. Unconditional portfolio policies are rejected in favor of conditional policies. Lower order polynomials are rejected in favor of higher order polynomials. Optimal stock and bond allocations are clearly countercyclical.     

Special economic zones: Shortcut or roundabout way towards capitalism?

The experiences of developing countries suggest that special economic zones (SEZs) might be appropriate instruments for accelerating the economic restructuring of Central and Eastern Europe. What functions could SEZs fulfil in the transformation process? What conditions must be met if they are to be successful?

The impact of a change in exchange rate pass-through on U.S. imports

The Impact of a Change in Exchange Rate Pass-Through on U.S. Imports. - One import demand equation is specified that is potentially affected by a breakdown in pass-through and one that is not. From the difference in the forecasts of these two equations an upper-bound estimate is derived for the impact on U. S. non-oil imports of the breakdown in exchange rate pass-through during the 1980s. The empir-ical evidence suggests that exchange rate pass-through may have changed after 1985. Without this shift in pass-through U. S. non-oil imports may have been a maximum of 15 percent lower by 1990.     

A Simple Axiomatization of the Foster, Greer and Thorbecke Poverty Orderings

The paper presents a simple characterization of the poverty orderings which are represented by a poverty measure belonging to the Foster, Greer, and Thorbecke class. All properties introduced are formulated within an ordinal framework. Furthermore, a new concept is proposed: the equivalent societal income which—if given to each individual in society—yields the same level of poverty as the actual income distribution. It is a specific indicator of the underlying poverty ordering, has attractive properties and allows us to prove the main result in a direct way.     

Consumer protection in Switzerland by means of “soft law” — Practices and perspectives

Consumer protection by self-regulation has come into focus as a proposed alternative to consumer legislation. This paper tries to show the principal forms in which soft law rules have been established in Switzerland, and to outline some of the main problems to which they have been exposed in practice.To a great extent self-regulation has centered, up to now, in the hands of the trade itself, although consumer organisations participate in some commissions for extra-judicial settlement. The principal deficiencies of self-regulation concern its enforcement and its scope of applicability when the trade is organised only to a limited extent. It has also been prowed that the drawing up of soft law rules has hindered legislation and, in some instances, also court practice.The authors come to the conclusion that some of the conditions without which soft law cannot achieve an effective impact on the trade are missing in Switzerland. However, positive contributions of soft law to consumer protection can sometimes be discerned where legislation has not succeeded.

Zusammenfassung Die Schwierigkeiten, denen die Verbrauchergesetzgebung auch in der Schweiz begegnet, haben dazu geführt, dass die von der Wirtschaft als Alternative vorgeschlagene Selbstkontrolle stärker in den Mittelpunkt des Interesses gerückt ist als bisher. Der Artikel versucht — soweit ersichtlich, erstmals —, die verschiedenen Erscheinungsformen von soft law in der Schweiz aufzuzeigen und die wesentlichen Schwierigkeiten herauszuarbeiten, denen es in der Praxis begegnet.Die Selbstkontrolle der Wirtschaft bei Verbrauchergeschäften liegt zum grossen Teil ausschliesslich in den Händen der Wirtschaftsverbände. Die Verbraucherorganisationen beteiligen sich an ihr, auch aus finanziellen und personellen Gründen, nur zurückhaltend, wobei der Schwerpunkt dieser Beteiligung in der aussergerichtlichen Streitbeilegung und nicht in der Erarbeitung von materiellrechtlichen Regeln zu finden ist. Der Staat ist bis heute nur in einem Einzelfall interveniert, um eine effektive Selbstkontrolle zu gewährleisten.Die Hauptschwächen von soft law betreffen seine Durchsetzung und die Weite seines Anwendungsbereichs, zumal die verschiedenen Branchen in der Schweiz nur teilweise in repräsentativen Wirtschaftsverbänden organisiert sind. Bedenklich ist insbesondere der negative Einfluss, den soft law-Regelungen auf die Fortentwicklung der Verbrauchergesetzgebung und teilweise auch der Rechtsprechung ausgeübt haben.Einige unabdingbare Voraussetzungen für einen effektiven Verbraucherschutz durch Selbstkontrolle sind in der Schweiz nicht gegeben. Gleichwohl trägt das soft law vornehmlich in den Bereichen zum Verbraucherschutz etwas bei, in denen eine Gesetzgebung bisher nicht möglich war.
