Ranking Crop Yield Models: A Comment

This comment discusses key specification issues that may have affected the performance and, therefore, the ranking of parametric models that were compared in a recent AJAE article. A procedure to obtain the most flexible parametric model specification possible, given the particular probability distribution function on which the model is based is presented. These specifications also allow for standardized and, therefore, more valid comparisons across parametric models that are based on different probability distributions. Finally, the comment cautions against generalization of the rankings in that AJAE article and recommends that these more flexible specifications be adopted in future comparisons and applications.     

The role of FDI in structural change: Evidence from Mexico

Foreign direct investment (FDI) flows to Mexico are substantial and play an important role in the Mexican economy since the mid-1990s. These investments reflect the activities of multinational firms that shape to some extent the economic landscape and sectoral structure in this host country. We illustrate that there is considerable variation in the amounts of FDI and structural change within the country and across time. Based on this, the paper's main purpose is to analyse whether there is a significant impact of FDI on structural change. We conduct an empirical analysis covering the period 2006–16. We use the fixed-effects estimator where the unit of observation is a Mexican state for which we calculate structural change from the reallocation of labour between sectors. The results suggest that (if any) there is a positive effect from FDI on growth-enhancing structural change. This effect depends critically on the lag structure of FDI. Moreover, there is some evidence that the positive effect (a) arises from FDI flows in the industry sector and (b) is present for medium and low-skilled labour reallocation.     

Economic Value of the Carbon Sink Services of Tropical Secondary Forests and Its Management Implications

This paper explores the economic feasibility of secondary forest regeneration and conservation as an alternative in the campaign addressing the problem of global warming. Detailed measurements of tropical secondary forests over time, in different ecological zones of Costa Rica, are used to evaluate carbon storage models. The paper addresses key issues in the international discussion about cross- and within-country compensation for carbon storage services and illustrates a method to compute/predict their economic value over time under a variety of scenarios. The procedure is applicable to other developing countries where secondary forest growth is increasingly important.     

Fiscal Cyclicality in the Brazilian Economy: Something Is Changing

This article provides empirical evidence of the degree of fiscal cyclicality in the Brazilian economy from 2000 to 2010. The degree of fiscal cyclicality is estimated through OLS and GMM models for three different time samples with the objective of observing a change in the stance in the conduct of fiscal policy. The fiscal policy from January 2000 to December 2010 was countercyclical. However from 2000 to 2007 the search for credibility implied a cyclical fiscal policy. In contrast, after 2007, the possibility of using a countercyclical fiscal policy became feasible.     

PUBLIC SERVICES IN THE AREA OF THE SOCIAL ECONOMY IN ARGENTINA

ABSTRACT*: The author describes the development of the public sector of the social economy in the last few years. The state-owned companies with significant participation in the economic activity of the country were privatized within the so-called State Reform Scheme (Law 23696), beginning in 1990. Privatizations are still being carried out, but the main activities that were formerly in the hands of the state (electricity, transport, public service) are now in the hands of the lucrative private sector (corporations, mainly of foreign origin). The policy regarding the transfer of these companies has not favoured the social economy sector.     

Foreign direct investment (FDI) determinants and spatial spillovers across Mexico's states

This article studies the location pattern of foreign direct investment (FDI) in Mexico for the period 1994–2004. An empirical model is specified based on recent FDI theories. This model is estimated using state-level data and employing spatial econometric techniques. Results suggest that higher education levels and lower delinquency rates are important determinants to attract FDI. Results also suggest a relationship of complementarity between inbound FDI to the host state and inward FDI to its neighboring states.     

An analytical framework for retailer price and advertising decisions for products with temperature-sensitive demand

The demand for weather-sensitive products, such as beverages, ice creams, or chocolate varies with changes in temperature. Yet, retailers lack a framework to adapt the marketing mix elements, such as price and advertising, in line with such changes. We provide a theoretical framework to fill this gap by developing an analytical model to derive the optimal marketing mix when product demand depends on temperature. The model prescribes how price and advertising for different demand characteristics should be set following a temperature change. Integrating the temperature element in the marketing mix offers an original profit-enhancing strategy.     

“Author’s Reply: Critique of Mexico’s New Social Security Act”, Octavio Maupomé-Carvantes,July, 1999

Abstract

This paper considers the pension plan as part of the capital structure of the sponsoring employer. This enables lessons from financial theory concerning capital structure to be used to answer the question, “What assets should a pension fund hold?” The standard Modigliani-Miller framework is expanded on to consider the implications of corporate tax. This leads to the conclusion that bond investment for pension plans has tangible advantages over holding risky assets (e.g., equities). The paper considers a case study of the pension plan of the Boots Company, a U.K. pharmacy retailer with a pension fund of around £2.3 billion ($3.5 billion), where these ideas were put into practice. Finally, the paper discusses the value released to shareholders and the extra security members of the pension fund have derived from putting theory into practice.
