Decentralization and Financial Equilibrium in a Centrally Planned Economy (CPE)

This paper deals with the fundamental problem of socialist economies: how to ensure compatibility of financial equilibrium with efficient allocation of resources in a decentralized decision-making system. In order to ensure rational allocation of resources in a decentralized system, it is indispensable to apply marginal pricing of labour, materials and foreign currencies. In order to ensure financial equilibrium on the consumer market the financial system operates with average cost pricing rules, thus violating efficiency rules. Trying to solve this dilemma the constructors of economic reforms of the system give priority to financial equilibrium conditions by using average cost prices and exchange rates and correct them by subsidies differentiated for branches. This leads to bargaining processes and to the neglect of efficiency rules. The author proposes instead the use of a uniform subsidy of the central budget and presents variants of this systemic solution: in the form of a uniform subsidy to wage earners or in the form of a uniform subsidy to enterprises. The formalized analysis is included in the appendix

Energy: Prospects and Policy Issues in Intra-CMEA Relations

This paper presents an exploratory review of publications dealing with past trends and projections concerned with energy in intra-CMEA relations. The research should be useful in the identification of directions for IIASA's research on "Mineral Markets and Trade". I hope that the collection of materials presented here may also be looked upon as the first stage of a study of energy-related issues in intra-CMEA relations. Due to the strict time-limit imposed on this work, it was not possible to review all of the non-CMEA publications listed in the bibliography. However, the main weakness of this research lies in the lack of information from CMEA countries. This could possibly be overcome by collaborating directly with institutes in CMEA countries. Without this information, this review should be regarded as an incomplete working draft

High accuracy Raman measurements using the Stokes and anti-Stokes lines

We show that by measuring the separation between the Stokes and anti-Stokes peaks excited by two different laser lines we obtain a very precise determination of absolute phonon energies. The method is useful for measuring small changes of these energies with strain, temperature, laser power, etc. It doubles the changes and avoids the necessity of using the reference lines in the Raman spectra. The method can be applied for the determination of phonon deformation potentials, for the characterization of strained heteroepitaxial layers, and for micro-Raman analysis of strain in silicon integrated circuits. We give examples of phonon shifts in Si, Ge, GaAs, InAs, and GaP as a function of applied biaxial strain, laser power, and [email protected] ; [email protected]
