A Latin American Perspective on Trade Policies

This article looks at the trade policy guidelines that the region should follow in order to achieve dynamic international economic linkages, in the light of the international context, the theoretical debates on this subject, and some lessons that may be learned from the study of successful cases. It is posited that in the countries of the region, trade policy can be an instrument for macroeconomic management, fiscal management, and, at the microeconomic level, resource allocation. Its use as a second-best instrument is justified when there are constraints on the use of the best possible solutions. It is also held that there must be close coordination of the policies applied in the fields of trade, industry, and technology to ensure high levels of investment in the tradeable sectors of the economy, a form of competitiveness based on constant increases in productivity, and an improvement in the region's specialization profile. Finally, emphasis is placed on the need to strengthen the institutions of Latin American states in order to ensure that their interventions in the economy have a suitable level of effectiveness.     

Human resource management for learning through knowledge exploitation and knowledge exploration: Pharmaceuticals in Mexico

This paper investigates the influence of human resource management practices on the likelihood that a firm performs in-house R&D. R&D is broadly interpreted as learning—a mechanism promoting absorptive capacity and supporting technology capability-building. Firms can choose between two learning strategies: they can exploit existing knowledge, or perform more complex explorations and acquire new knowledge. Different knowledge requirements associate with distinct R&D outcomes with varying degrees of novelty for the firm. Findings are supported with evidence from the pharmaceutical industry in Mexico. The analysis reveals positive linkages between human resource management practices and learning at firm level. The relationship is contingent on factors such as expected R&D outcomes, or the novelty of the knowledge required by the firm. The provision of training revealed the more consistent, positive influence on the likelihood that pharmaceuticals firms perform R&D in Mexico.     

Protection of the weak consumer under product liability rules

The author examines how the weak consumer is treated in one of the main areas of consumer protection, namely product liability. One should distinguish between the weak consumer in a physical sense, especially children, elderly or disabled persons, and in an intellectual sense, namely people with insufficient education or illiterates. If the judge in product liability cases uses the model of the average consumer as a standard to determine the defectiveness of a product, weak consumers will be underprotected. The author suggests that, if the product may be used by a set of weak consumers, the producer should provide for adequate safety measures directed at this group. On the other hand, there is a third kind of weak consumer, namely the weak consumer in an economic sense. The raising of producer's liability may result in an increase in prices for products harmful to low income consumers. Therefore, consumer policy should aim at a reduction in social inequalities.

Schutz des schwachen Verbrauchers im Produkthaftungsrecht

Zusammenfassung Der Autor untersucht die Stellung des schwachen Verbrauchers in einem der zentralen Gebiete des Verbraucherschutzrechts, nämlich der Produkthaftung. Dabei sollte man zwei Typen von Schwäche unterscheiden: einmal in einem physischen Sinne, etwa Kinder, ältere Menschen, Behinderte, dann in einem intellektuellen Sinn, etwa Menschen mit unzureichender Schulbildung, Analphabeten, in gewisser Weise auch der Landessprache nicht mächtige Ausländer. Wenn der Richter in Produkthaftungsstreitigkeiten den Durchschnittsverbraucher als Maßstab zur Bestimmung der Sorgfaltspflicht des Herstellers verwendet, so ist der schwache Verbraucher nur unzureichend geschützt. Der Autor schlägt vor, daß in den Fällen, in denen ein Produkt auch zum Gebrauch einer Gruppe von schwachen Verbrauchern bestimmt ist, der Hersteller hinreichende Schutzmaßnahmen auch und gerade für diese spezifische Verbrauchergruppe unternimmt. Dies mag zu einem Preisanstieg für solche Produkte führen, was gerade den ärmeren Verbrauchern Nachteile bringt. Aus diesem Grunde muß die Verbraucherpolitik soziale Disparitäten beseitigen.

When does universal peace prevail? Secession and group formation in conflict

This paper analyzes secession and group formation in the general model of contests due to Esteban and Ray (1999). This model encompasses as special cases rent seeking contests and policy conflicts, where agents lobby over the choice of a policy in a one-dimensional policy space. We show that in both models the grand coalition is the efficient coalition structure and agents are always better off in the grand coalition than in a contest among singletons. Individual agents (in the rent seeking contest) and extremists (in the policy conflict) only have an incentive to secede when they anticipate that their secession will not be followed by additional secessions. Incentives to secede are lower when agents cooperate inside groups. The grand coalition emerges as the unique subgame perfect equilibrium outcome of a sequential game of coalition formation in rent seeking contests.

Optimal growth and land preservation

A model of optimal economic growth with a constant population subject to a constraint on the availability of land is presented. It takes account of the dual character of land as a production factor and as a consumption good (environmental amenities) by determining the optimal intertemporal allocation of land between productive and recreational uses. An extension of the analysis for the case of a growing population with endogenous growth based on human capital accumulation shows that if the rate of discount is not very low, then there exists a set of balanced growth paths compatible with a constant allocation of land.     

Assistance to poor households when income is not observed: targeted in-kind and in-cash transfers

Policymakers frequently design self-targeting programs or target poor areas to assist poor families when income is not observed. Self-targeting schemes take advantage of differences in participation costs in assistance programs across households. Geographic targeting assumes that transfers are solely determined by the region of residence: to receive the benefits, households not initially present in the targeted areas must relocate away from their original place of residence and live with the poor, which entails a cost that can also be interpreted as a participation cost in the assistance program. The paper shows that a combination of in-kind and in-cash transfers tied to the consumption of a publicly provided private good targeted to the poor becomes very useful when non-poor households have different participation costs. By distinguishing users and non-users of public facilities additional in-cash transfers can be directed to the poor more effectively. The paper demonstrates that the publicly provided good ends up being undersupplied, and the distortion becomes less important as participation costs rise. More importantly, it shows that this kind of redistributive program dominates a pure in-cash scheme.     

THE IMPACT OF FISCAL DECENTRALIZATION: A SURVEY

In this paper, we offer a comprehensive and updated review of the impact of fiscal decentralization on the economy, society and politics. Our first target is the examination of two crucial and yet unsolved issues in the empirical literature on decentralization: the proper measurement of decentralization itself and its potential endogeneity in econometric estimates. Then, we discuss the main existing findings on the effects of decentralization on a relevant list of socio-economic issues. The impact of fiscal decentralization reforms on political institutions and public policies is also considered. Complete answers on the impact of fiscal decentralization are not likely to be certain but, overall, there are reasons to be optimistic about the net positive result. Our survey by necessity has to be selective but it presents a balanced view of what is known and what is not yet known opening room for further research and practice on fiscal decentralization.     

Modeling a Dynamic Portfolio for Pension Plans in Emerging Markets With Myopic and Nonmyopic Behavior

ABSTRACT

We introduce a dynamic formulation for the problem of portfolio selection of pension funds in the absence of a risk-free asset. In emerging markets, a risk-free asset might be unavailable, and the approaches commonly used may no longer be suitable. We use a parametric approach to combine dynamic programming and Monte Carlo simulation to gain additional flexibility. This approach is general in the sense that optimal asset allocation is tractable for all HARA utility functions in the absence of a risk-free asset. The traditional case composed of several risky assets and one risk-free asset is compared to a case in which the risk-free asset is unavailable.     

Holt’s exponential smoothing and neural network models for forecasting interval-valued time series

Interval-valued time series are interval-valued data that are collected in a chronological sequence over time. This paper introduces three approaches to forecasting interval-valued time series. The first two approaches are based on multilayer perceptron (MLP) neural networks and Holt’s exponential smoothing methods, respectively. In Holt’s method for interval-valued time series, the smoothing parameters are estimated by using techniques for non-linear optimization problems with bound constraints. The third approach is based on a hybrid methodology that combines the MLP and Holt models. The practicality of the methods is demonstrated through simulation studies and applications using real interval-valued stock market time series.
