In a recent paper, Yoram C. Peles and Meir I. Schneller (1989) ignore the sampling autocorrelation bias. A replication of their work that removes the bias changes their results. With the bias removed, there is no evidence that their three long-term ratios follow an adjustment process. Copyright 1992 by MIT Press.

A nonparametric analysis of agricultural production behavior was conducted for each of the contiguous forty-eight states for the period 1956-82 under the joint hypothesis of profit maximization, convex technology, and nonregressive technical change. Tests were conducted in each state for profit maximization and for constant returns to scale. Although considerable variability was observed among states, measurement errors of magnitudes common in secondary data yielded test results fully consistent with the profit-maximization hypothesis in all states with complete output and input data.

The ability of planners in Poland and the U.S.S.R. to recognize and act to eliminate market disequilibrium in the markets for grain and meat is tested by means of an econometric model of grain and meat production, consumption, and trade. Planners' perceptions of excess demand for grain, meat, and foreign exchange are shown to influence production and trade decisions in a way that tends to reduce excess demand or supply. Nevertheless, the markets for grain, meat, and foreign exchange are shown to be characterized by excess demand or supply for much of the sample period. Copyright 1992 by MIT Press.
