New patterns of consumer protection under warranty law: Lessons from the U.S. magnuson-moss warranty act

Warranty law appears to be a relevant instrument for granting protection to consumers against product disappointment. However, empirical studies concerning some warranty markets both in the United States and in West-European countries show that there continues to be no bargaining on warranties between sellers and buyers, that the most serious risks are all allocated to the user of the product, and that consumers are generally not granted an actual opportunity of challenging a breach of warranty and getting adequate compensation for losses sustained. The Magnuson-Moss Warranty-Federal Trade Commission Improvement Act which was enacted in the United States in 1975 constitutes a first comprehensive and consumer-oriented reform of traditional warranty law. It foresees new patterns of consumer protection under warranty statutes, combining warranty substance regulation with warranty information, administration, and litigation procedures. This paper first describes the Act's major provisions; it also points out some of its deficiencies. Although criticisms are formulated against the Act's ideology or basic assumptions, it is the author's opinion that it represents a decisive step towards legislative and administrative participation in the formulation of warranties. The Act undoubtedly suggests some, though not identical, avenues of reform that legislators and authorities of European countries and confederations should now propose in order to increase consumer protection against defective or unsatisfying products.

Exports and labor costs: evidence from a French policy

We investigate the role that labor costs hold in exporters’ performance. To do so, we exploit a large-scale French reform that granted most firms a tax credit proportional to the wagebill of their employees paid below a given threshold. This policy effectively translated into a cut in labor cost whose magnitude varies depending on firm-specific wage structures. We use the predicted treatment intensity based on pre-reform composition of the labor force as an instrument for the actual policy-induced firm-level change in labor costs. Although our point estimates are consistent with commonly estimated firm-level trade elasticities combined with reasonable labor shares in total costs, coefficients are found to be very noisy, suggesting lack of robust evidence of a causal effect of the policy. We discuss several potential explanations for our results as well as their implications.     

Incentives for cost misrepresentation in supply chains

This paper investigates sequential manufacturer–retailer price determination and channel performance under possible misrepresentation by one member of its privately known cost. To the standard double marginalization game, we add a preliminary stage where the manufacturer (alternately the retailer) announces its privately known constant marginal cost. We prove that the manufacturer has no incentive to misrepresent its cost, and we give respective sufficient conditions on the demand function for the retailer to overreport and to underreport costs. Depending on the shape of the demand function, opportunistic behavior by the retailer may lower or raise the manufacturer’s profit and channel performance.     

PRICING OF AMERICAN PATH-DEPENDENT CONTINGENT CLAIMS

We consider the problem of pricing path-dependent contingent claims. Classically, this problem can be cast into the Black-Scholes valuation framework through inclusion of the path-dependent variables into the state space. This leads to solving a degenerate advection-diffusion partial differential equation (PDE). We first estabilish necessary and sufficient conditions under which degenerate diffusions can be reduced to lower-dimensional nondegenerate diffusions. We apply these results to path-dependent options. Then, we describe a new numerical technique, called forward shooting grid (FSG) method, that efficiently copes with degenerate diffusion PDEs. Finally, we show that the FSG method is unconditionally stable and convergent. the FSG method is the first capable of dealing with the early exercise condition of American options. Several numerical examples are presented and discussed. ²     

Non-Europe: The magnitude and causes of market fragmentation in the EU

Non-Europe: The Magnitude and Causes of Market Fragmentation in the EU. — In 1985 the European Commission diagnosed its member states as suffering from excessive market fragmentation, later referred to as “Non-Europe.” The authors examine the empirical basis for the Commission’s diagnosis using a trade model derived from monopolistic competition. They then investigate the links between the initial size and subsequent evolution of border effects within the EU. The findings support the view that European consumers act as if imports from other members were subject to high nontariff barriers. However, there appears to be almost no relationship between market fragmentation and the barriers that were identified and removed by Europe’s Single Market Programme.
