Cross-border restaurant price and exchange rate interactions

Purchasing power parity suggests that international price ratios for identical goods should approximate nominal exchange rates for the currencies in which the prices are denominated. Deviations of the price ratios from exchange rates can occur for a number of reasons and mixed evidence has been recorded for how long those deviations last. Empirical evidence for international restaurant prices in El Paso, Texas and Ciudad Juarez, Mexico confirms that menu item price ratios are strongly correlated with the peso/dollar exchange rate. An earlier exploratory study of eight individual products also indicated that half-life deviations in this market are very short. This study utilizes additional data from a larger and more extensive sample to examine if the prior results are confirmed.     

Yardstick Competition and Quality

This paper explores the consequences for quality of introducing yardstick competition in duopoly when a verifiable quality indicator is available. Yardstick competition can be implemented by a menu of transfers that are linear in the cost differential between the two firms and in quality. Cost- and quality incentives are stronger in larger firms when improvements are highly valued by consumers and firms can significantly influence quality. Expenditures on quality improvement can increase or decrease following the introduction of yardstick competition. The crucial factor is the likelihood ratio of productivity between the two firms, not productivity differences.     

The Quest for Economic Stability: Roosevelt to Reagan

We investigate whether positional concerns (Veblen [1899] 1970; Hirsch, 1976) vary along several dimensions and domains, namely goods vs. bads, private vs. public, oneself vs. oneself s children, socially visible vs. nonsocially visible. Using a hypothetical survey in France, we replicate the empirical strategy of Solnick and Hemenway (1998; 2005) and test a larger set of socio-demographic variables that can be related to positional concerns. Despite some differences, our results are mostly consistent with those of Solnick and Hemenway (1998; 2005). We emphasize some policy implications.     

Life‐Cycle Consumption and Children: Evidence from a Structural Estimation

I estimate by maximum likelihood a dynamic model of optimal intertemporal allocation of consumption in the presence of children using high‐quality Danish longitudinal data. The number and age of all children can affect the marginal utility of consumption while income uncertainty, credit constraints and postretirement motives also influence household behaviour. While I estimate that children have a surprisingly small effect on the marginal utility of non‐durable consumption, data simulated from the estimated model replicates similar correlations between log consumption growth and changing household composition as found in the Danish data and typically found in UK and US data. To reconcile the results with existing studies, I illustrate how ignoring precautionary motives increases the estimated importance of children. The results indicate that precautionary motives might play a larger role than children in explaining the observed consumption age profile.     

Sovereign wealth funds: National security risks in a global free trade environment

The proliferation of sovereign wealth funds (SWFs) has resulted in an unstable political, legal, and regulatory environment for this form of foreign direct investment (FDI). This article explains SWF growth over the last half‐century; discusses issues surrounding SWF “transparency” and host‐country national security risk; reviews the legal and regulatory structures governing FDI in major national economies; examines proposed regulatory approaches to structure the FDI environment; and concludes with a discussion of SWF regulatory policy recommendations addressing corporate governance principles, national security restrictions on equity investment, and investment reciprocity, and suggests recommendations for executives considering engaging an SWF investment partner. © 2009 Wiley Periodicals, Inc.     

Technological change: A microeconomic approach to the creation of knowledge

Technological change does not evolve in a purely normative economic way. Economic selection has a guiding impact on technology evolution, but the generic element of novelty does not necessarily follow economic utility. In general, market selection is predominant in economic thinking and it is also implicit in the literature on technological change. Using a microeconomic approach to the creation of knowledge, this paper shows that the generic (Schumpeterian) element of the emergence of novelty – economic selection being absent – may create structures, paradigms and trajectories, which we usually look at from a market selection perspective. This paper does not try to make predictions on trajectories, but it qualifies a standard evolutionary perspective.     

An experimental investigation of soft price caps in uniform price auction markets for wholesale electricity

This paper presents the results from an auction experiment using industry professionals and student participants who compete in a simulated wholesale market for electricity. Motivated by the intervention by FERC in response to the “meltdown” of the California spot market, we investigate the effect of including a “soft” price cap in a uniform price auction as a means of mitigating high prices. When prices are driven above the soft cap, offer curves become flat, in contrast to the hockey stick shape observed in a typical uniform price auction for electricity. This flat offer curve leads to market prices that are relatively insensitive to both generation costs and demand reductions.      

Parental Compensatory Behaviors and Early Child Health Outcomes in Cebu, Philippines()

A dynamic optimization model of parents choosing investments in their children's health motivates an empirical model of parents' choices of health inputs for their children and the impacts of these decisions on their children's subsequent health. Estimates of the child health input demand functions and the child health production functions from the Cebu Longitudinal Health and Nutrition Survey accord with the prediction that optimizing behavior results in higher levels of aggregate child health. Observable parental behaviors respond to the physical developmental status of their children. These parental responses appear to yield large and statistically significant improvements in children's early physiological outcomes. However, because some health inputs choices are not observable, it is impossible to ascertain whether these measured effects are due solely to variations in the observed input choices.     

Fair welfare maximization

We consider the general problem of finding fair constrained resource allocations. As a criterion for fairness we propose an inequality index, termed “fairness ratio,” the maximization of which produces Lorenz-undominated, Pareto-optimal allocations. The fairness ratio does not depend on the choice of any particular social welfare function, and hence it can be used for an a priori evaluation of any given feasible resource allocation. The fairness ratio for an allocation provides a bound on the discrepancy between this allocation and any other feasible allocation with respect to a large class of social welfare functions. We provide a simple representation of the fairness ratio as well as a general method that can be used to directly determine optimal fair allocations. For general convex environments, we provide a fundamental lower bound for the optimal fairness ratio and show that as the population size increases, the optimal fairness ratio decreases at most logarithmically in what we call the “inhomogeneity” of the problem. Our method yields a unique and “balanced” fair optimum for an important class of problems with linear budget constraints.
