Unilateral and bilateral trade policies for a minimum-wage economy

This paper considers optimal commercial policy for a trading economy which departs from neo-classical characteristics only in that a minimum-wage constraint gives rise to unemployment. Although for a flexible-wage fully employed economy the Baldwin envelope yields dominant domestic production-cum-trade possibilities, unilateral imposition of an optimum tariff is shown not necessarily to be optimal commercial policy for the minimum-wage economy. Rather, there exists an envelope, derived from foreigners' trade indifference and attained via bilateral trade policy, which dominates the Baldwin envelope when the optimum tariff is zero (as Brecher has shown it can be for a minimum-wage economy), and can still yield superior production-cum-trade possibilities when the optimum tariff is non-zero.     

SOME RECENT RESEARCH INTO HOME HEATING

As part of an investigation into the performance of heating systems and the effectiveness of energy saving measures, temperatures have been monitored in forty centrally heated homes. The addition of extra insulation had no effect on the way people operated their heating system or on the temperature level set in the main living room. However, bedrooms were warmer and the importance of individual room temperature controls demonstrated. Differences between people's thermal requirements in domestic and office environments are considered.     

ALTERNATIVE PRODUCTION FRONTIER METHODOLOGIES AND DAIRY FARM EFFICIENCY

This paper estimates technical efficiency (TE) measures using four alternative production frontier models, and evaluates the sensitivity of the results to the choice of methodology. The Cobb-Douglas functional form along with data for 1982 and 1983 from 404 dairy farms located throughout six northeastern states in the US are used in the estimation. A general conclusion is that, broadly speaking, frontier function models are neutrally upwardly scaled versions of the OLS or average model. A second conclusion is that different models yield markedly different efficiency levels across firms. However, the correlation between the indexes from the various methods is high, which implies that the ordinal ranking of firms according to their measured level of technical efficiency appears to be independent of the method used for a given year. By comparison, the correlation between efficiency indexes for the same method across time, although positive, is much lower than the previous set of correlations. Correlation analysis of efficiency versus farm size and of efficiency versus returns over variable costs, based on the alternative models, yielded consistent results.     

Allocative efficiency measurement with endogenous prices

In the nonparametric measurement of allocative efficiency, output prices are fixed. If prices are endogenous, the overall output in the market determines the allocative efficient point. We develop an alternative semi-nonparametric model that allows prices to be endogenously determined.     

Nurse shortage or nursing shortage: have we missed the real problem?

Many strategies have been used to solve the nurse shortage. The shortage of nurses has in many ways alerted us to the need to provide safe and efficient care using the latest technology. Nursing needs to adopt, refine, and use this technology so the impact of the nursing shortage is just another statistic and not a disruptive and costly threat to the public.     

The Effect of Subsidized Housing on Values of Adjacent Housing

This is a case study of the effect of subsidized housing on the value of adjacent non-subsidized housing. Four townhouse clusters in Fairfax County, Virginia, were selected for study because of the high degree of homogeneity between clusters. The clusters are all in the same community but vary in distance from subsidized housing. Sale prices were analyzed using a regression model which included distance from subsidized housing as an independent variable. Based on the results of the regression analysis, the authors conclude that the subsidized housing had a negative impact on the values of adjacent properties.
