On the theory of macroeconomic quasi-equilibria

Conclusion It has been shown that for the Classical System a quasi-equilibrium cannot exist, unless we make the ad hoc assumption of inflexible nominal wages⁸. The equilibrium in the classical regime corresponds to the general competitive equilibrium, and of course the validity of Walras' Law cannot be questioned. At the same time, however, it has been shown that to extend these conclusions to the Keynesian system as well is not justified. The Keynesian system has, in general, a quasi-equilibrium. The model constructed in this paper and the resulting conclusions are significant because the model: (a) Incorporates the Keynesian notion of effective demand, which includes the demand for capital goods (investment) as being performed by a group of people distinct from the consumers (and so, answering Negishi's point, there is a prince in Hamlet!), (b) Unlike other models (like the recent paper by Glustoff), it does not rely on nominal wage rigidity to explain unemployment, but instead, again answering Negishi's remark, it explains rather than postulates why real wages do not adjust in the presence of unemployment so as to eliminate it. (c) It verifies the validity of Clower's proposition that in the Keynesian System Walras' Law holds only in equilibrium. (d) It reconsiles Bent Hansen's original quasi-equilibrium model with the Keynesian proposition of an unemployment equilibrium, against the apparent view of Hansen that to do that would require the assumption of a Phillips curve, a view also shared by Arrow and Hahn, and many others.An earlier version of this paper was presented in the December 1974 meeting of the Econometric Society in San Francisco. The author wishes to thank Prof. R. Clower, Prof. B. Hansen, Prof. S. Black, and Dr. G. Winckler for their valuable comments, but he obviously claims any errors for himself.     

On a use of stratified sampling in optimal estimation

Summary Postulating an intra-class correlation structure for a finite population vector of variate — values optimal stratified and unstratified strategies for estimating the total are identified and relative efficiencies noted. Higher efficiency of stratified over unstratified sampling is demonstrated for usual estimators in ppswr case, in particular. In the uncorrelated case appropriately chosen two-stage strategies are observed to fare at par with optimal stratified ones.     

Productivity,earnings, and profit sharing — An econometric analysis of alternative models

The theoretical status of the relationship between productivity, wages, and profit sharing (PS) is poor. Only some alternative hypotheses can be formulated. From these explanations six different econometric models are derived. Using data of the German Socio-Economic Panel the models are estimated and tests and indicators are employed to choose the best model. Our investigation speaks in favour of hybrid simultaneous Tobit models where the level of profit sharing is positively correlated with productivity which induces positive wage effects on the one hand. But on the other hand the level of wages is also relevant to the question whether a firm introduces or decides to continuePS and which amount ofPS should be paid.What is obvious is not always true and introspection is a notoriously unreliable guide to empirical magnitudes.

Unemployment insurance and union bargaining — an insider-outsider approach

A trade union is required to tax its own members to fund unemployment benefit paid to its unemployed members in an insider-outsider model of union bargaining over wages and employment. An increase in unemployment benefit imposed by the government increases employment overall but not necessarily the employment of insiders if the tax rate is exogenously fixed by the government.This paper has benefited from comments of Mick Common, Dipak Ghosh, Bob Hart, and Robin Ruffell. The comments of two anonymous referees and the advice of the Editor have greatly improved the presentation of the paper. Any remaining errors or omissions are the responsibility of the authors.

Total factor productivity and R&D capital in the spanish economy, 1965–1980

A formal model of productivity growth and technical progress is presented. The model takes into account embodied and disembodied technical progress as explanatory variables. The slowdown in productivity growth for the Spanish economy after 1972 is explained for 92% by the decline in the rate of growth of technical progress originated from domestic R&D and technology imports.     

Karoushi: Stress-death and the meaning of work

The present article is concerned with some of the human factors involved when overtime and overwork become part of the regular and accepted pattern of work, with sometimes tragic results. While the economic miracle of Japan can be much admired, it has not been without human cost. Only recently, national and global attention is being focused on a new and deadly phenomenon in Japan:Karoushi, which the Japanese define as death from overwork, and which I choose to re-define as stress-death related to feelings of helplessness.It is my tentative hypothesis thatkaroushi is not directly caused by overwork, as popularly assumed. Rather, I believe that overwork is only one factor, and that stress-death is actually caused by the cumulative, long-range effects of working in a situation where one feels trapped and powerless to effect any change for the better, which in turn leads to attitudes of hopelessness — attitudes which are exacerbated, rather than ameliorated, by environmental and managerial factors.Dr. Walter Tubbs received his Ph.D. in Neuropsychology and Philosophy after doing work at Stanford and Drew Universities. After involvement in brain research at Stanford, he practiced stress-management counseling and biofeedback training at Loma Linda University, and taught for 13 years at the University of Redlands in California. He has been in Japan for 11 years as a Senior Researcher.
