Majority Voting in Multidimensional Policy Spaces: Kramer–Shepsle versus Stackelberg

We study majority voting over a bidimensional policy space when the voters’ type space is either uni‐ or bidimensional. We study two voting procedures widely used in the literature. The Stackelberg (ST) procedure assumes that votes are taken one dimension at a time according to an exogenously specified sequence. The Kramer–Shepsle (KS) procedure also assumes that votes are taken separately on each dimension, but not in a sequential way. A vector of policies is a Kramer–Shepsle equilibrium if each component coincides with the majority choice on this dimension given the other components of the vector. We study the existence and uniqueness of the ST and KS equilibria, and we compare them, looking for example at the impact of the ordering of votes for ST and identifying circumstances under which ST and KS equilibria coincide. In the process, we state explicitly the assumptions on the utility function that are needed for these equilibria to be well‐behaved. We especially stress the importance of single‐crossing conditions, and we identify two variants of these assumptions: a marginal version that is imposed on all policy dimensions separately, and a joint version whose definition involves both policy dimensions.     

Central Bank Policy Paths and Market Forward Rates: A Simple Model

Increasingly many central banks announce likely paths for future policy rates. Recent experience suggests that market forward rates can differ substantially from those announced. Models commonly adopted in policy analysis ignore such differences. This paper studies a simple model that can capture deviations between announced paths and market forward rates. We detail the macroeconomic transmission of such deviations and show how the model can inform policy deliberations.     

ECONOMIC LIBERALIZATION AND CHANGES IN CORPORATE CONTROL IN LATIN AMERICA

This article analyzes ownership restructuring and changes in corporate control in four large Latin American countries—Argentina, Brazil, Chile, and Mexico—during the 1990s. Drawing on original firm‐level data, this is a comparative study aimed at identifying cross‐country differences and regularities. It focuses on transactions associated with privatizations and private mergers and acquisitions (M&As)—their evolution, relative importance, and sectoral incidence—as well as the role played by different types of investors: local, foreign, and joint ventures. A specially built database was used in the analysis, comprising 3,085 private M&As and 329 privatization transactions. Although similar to processes occurring elsewhere, it is argued that ownership restructuring in Latin America was facilitated and fostered by specific changes in policy‐associated institutional framework conditions. That is, the wide‐ranging process of ownership restructuring is strongly associated with economic liberalization, which has become the main feature of Latin American national regimes of incentives and regulation.     

The Size and Incidence of the Losses from Noise Trading

Recent empirical research has identified a significant amount of volatility in stock prices that cannot easily be explained by changes in fundamentals; one interpretation is that asset prices respond not only to news but also to irrational “noise trading.” We assess the welfare effects and incidence of such noice trading using an overlapping-generations model that gives investors short horizons. We find that the additional risk generated by noise trading can reduce the capital stock and consumption of the economy, and we show that part of that cost may be borne by rational investors. We conclude that the welfare costs of noise trading may be large if the magnitude of noise in aggregate stock prices is as large as suggested by some of the recent empirical litrature on the excess volatility of the market.     

Positive Feedback Investment Strategies and Destabilizing Rational Speculation

Analyses of rational speculation usually presume that it dampens fluctuations caused by “noise” traders. This is not necessarily the case if noise traders follow positive-feedback strategies—buy when prices rise and sell when prices fall. It may pay to jump on the bandwagon and purchase ahead of noise demand. If rational speculators' early buying triggers positive-feedback trading, then an increase in the number of forward-looking speculators can increase volatility about fundamentals. This model is consistent with a number of empirical observations about the correlation of asset returns, the overreaction of prices to news, price bubbles, and expectations.     

The Effect of Information on Willingness to Pay for Canned Tuna Fish with Different Corporate Social Responsibility (CSR) Certification: A Pilot Study

The objective of this study was to assess the role of information in consumers' willingness to pay (WTP) for food products with corporate social responsibility (CSR) certification. The item used for the experimental design was canned tuna fish, a product on the market that is already exhibiting various kinds of certification related to social and environmental attributes. Two different kinds of certifications were examined, namely Friend of the Sea, which involves environmental aspects, and SA8000, related to workers' rights and more general social attributes. We implemented experimental auctions, taking into account three information treatments. The initial findings show that the WTP for both CSR labels is higher than the WTP for tuna fish without any CSR certification. Nevertheless, the information provided on CSR certification did not change consumers' WTP among the certification schemes. Our findings could also serve to fine‐tune marketing strategies to consumer preferences and determine which CSR activities are worth undertaking.     

Industrial Structure and Australia– UK Intra-Industry Trade

This paper tests industry-specific hypotheses of the determinants of intra-industry trade in the context of Australia-UK trade. In doing so it separates intra-industry trade (ITT) into ITT in horizontally differentiated products and ITT in vertically differentiated products. It finds that the latter is the dominant former of ITT. Further the paper investigates the robustness of empirical results on testing industry-specific hypotheses to the choice of national (UK or Australian) industrial structure characteristics. The assumption of uniform industrial structures across countries adopted in other studies is shown not to be justified.
