Exchange Rate Pass-Through to Consumer Prices: The Increasing Role of Energy Prices

Open Economies Review - A number of researchers have found that the rate of exchange rate pass-through (ERPT) to domestic prices has declined substantially over the last few decades. We revisit...     

The approximation capabilities of the minflex-Laurents,translog, and generalized Leontief forms

This paper compares the approximation capabilities of the minflex-Laurents translog and minflex generalized Leontief cost functions with their translog and generalized Leontief counterparts in Monte Carlo experiments. The minflex Laurent specifications generally provided closer approximations to underlying technical and economic parameters. Imposition of nonlinear restrictions on some of the parameters of the minflex Laurent models yielded measurable improvement in estimated elasticities of substitutions, returns to scale, and rates of technical change.The refereeing process of this paper was handled through E.

Antecedents of private label attitude and national brand promotion attitude: similarities and differences

A model that addresses the similarities and differences in conceptual antecedents of attitudes toward private label grocery products and national brand promotions is proposed and tested. The proposed model is tested using a sample of 300 consumers who were recruited from grocery stores, provided behavioral data from sales receipts of their shopping trip, and responded to a survey that contained multi-item construct measures. We predict and find in the study that both price and nonprice related constructs impact both private label attitude and national brand promotion attitude, but the directionality and strength of several of these relationships differ. Implications of these findings for retailers and national manufacturers are discussed.     

CAP Reforms in the 1990s and their Price and Welfare Implications: The Case of Wheat

We use a nonlinear commodity market model to assess, theoretically and empirically, the impacts of recent reforms of the CAP on prices and economic welfare in the EU. The empirical analysis is based on an aggregate structural econometric model of the EU wheat economy and its links to the rest of the world. Instability issues are also investigated. Impacts of CAP reforms on the variance of domestic and world prices are analysed and a Monte Carlo simulation is used to evaluate uncertainty in the model's welfare computations. Recent reforms led to a net welfare gain within the EU during the period 1993–2000. Additional budgetary costs are less than the welfare gains of consumers and producers. Producers gained as lower price support was overcompensated by additional direct payments.     

CONSUMER THEORY, HOME PRODUCTION, AND ENERGY EFFICIENCY

Arguments about the existence of the so-called energy efficiency gap are typically based on evaluations of efficiency measures as investments whose end result is to reduce the cost of providing a given level of energy services. This article demonstrates that the investment approach tends to undervalue energy efficiency improvements because it omits the increase in utility that results from the consumer's substitution of energy services for other goods. The substitution occurs because the efficiency measure reduces the marginal cost (implicit price) of energy services. Sample calculations based on a Cobb-Douglas utility function are used to illustrate the potential size of the undervaluation of efficiency investments.     

Age-test Markov chains for drug testing and detection

Random urinalysis strategies stratified by time since the last test are characterized with a set of Markov chain models. The probability of a person being tested depends on the amount of time since the person's last test. The Nuclear Regulatory Commission (NRC) has proposed a two strata drug testing strategy based on time since last test. The proposal included a high testing rate for people not yet tested in a given time period and a low testing rate for people testing negative in a given time period. Southern California Edison has implemented a variation of the NRC proposal. These strategies can be modeled within a Markov chain framework. Time to detection is calculated as a function of testing probabilities and drug usage levels. Drug user gaming strategies are discussed with illustrations. These models are implemented as part of a U.S. Navy drug policy analysis system.

Are physicians a “delinquent community”?: Issues in professional competence,conduct, and self-regulation

This paper examines the moral responsibilities of physicians, toward themselves and their colleagues, their students and patients, and society, in terms of the nature and exercise of professional self-regulation. Some of the author's close encounters with cases involving research misconduct, behavioral impairment or deviance, and medical practice at the moral margin, are described to illustrate why, in Freidson's words, physicians are a delinquent community with respect to the ways they meet their responsibility to govern the competence and conduct of their members. Judith P. Swazey, president of The Acadia Insttute, is co-author of The Courage to Fail: A Social View of Organ Transplants and Hemodialysis and co-editor of several books on medical responsibility.

International capital and nontraded goods in the long run

The present paper develops the comparative static properties of a small open economy which produces both traded goods and nontraded goods, and is a price taker in the international market for productive capital. Assumptions of full employment, competitive markets, and international mobility of productive cap ital input capture a long run horizon. Comparative static results associated with the wage, labor, and the price of the nontraded good are independent of factor intensity, factor substitution, and demand for the nontraded good. A tax on the traded good and a capital subsidy together raise national income and the real wage.
