In this article, we generalize the Carlson-Parkin (1975) method for the estimation of expected inflation rates based on qualitative surveys. An important generalization is that in our model, people's responses to the question given can be random while in the Carlson-Parkin method, they are not random. Second, alternative determinations of a threshold value are proposed. Third, the problem is treated with a gamma response function under a gamma distribution.

1 0 0 0 OA CONDITIONS ON CONSISTENCY FOR TESTING HYPOTHESES UNDER RATIONAL EXPECTATION BY VECTOR AUTOREGRESSIVE MODELS AND COINTEGRATION

The method of testing the cross-equation restrictions under the rational expectation (RE) hypothesis based upon the fitted vector autoregressive (VAR) time series models has been used. It has been applied to test the cross-equation restrictions implied by the expectation hypothesis for the term structure of interest rates, the present value relation in the stock market, and the efficiency hypothesis without risk premium in forward exchange rate market.We point out that two conventional econometric practices of the prefiltering (or differencing) and the use of law of iterated projection are often inconsistent with the restrictions imposed by the RE hypothesis. We explore the general relation between this inconsistency problem and the cointegrated stochastic processes. New sufficient conditions for logical consistency to test the restrictions imposed by the RE hypothesis are given. We show that some cointegrated filter can be used as a possible solution in some cases. Further, we propose a necessary and sufficient condition for testing the cross-equation constraints imposed by the RE hypothesis based upon the vector autoregressive moving average (VARMA) models, which can be useful as a solution to the difficulty caused by an improper use of the law of iterated projection.

1 0 0 0 OA ON THE TECHNICAL EFFICIENCY UNDER REGULATION: A CASE FOR THE JAPANESE ELECTRIC POWER INDUSTRY

著者: MAKOTO TAWADA SEI-ICHI KATAYAMA

This paper gives an empirical examination of efficiency of the regulated firm. Rate of return regulation is a typical feature of the public utility environment. The theoretical analysis by Averch-Johnson showed the existence of a regulatory bias toward overcapitalization. We reexamine and elaborate the method of the empirical test for the Averch-Johnson proposition. And we apply it to the Japanese electric power industry. We showed that the Averch-Johnson proposition was not necessarily confirmed and the production in the Japanese electric power industry was efficient for some period in spite of regulation.

1 0 0 0 OA ON THE EXCHANGE OF COST INFORMATION IN A BERTRAND-TYPE DUOPOLY MODEL

This paper deals with the welfare implications of information sharing between Bertrandtype duopolists when there is cost uncertainty. The paper distinguishes itself from the previous work in that it is not restricted to those special cases where goods are physically substitutes or costs are stochastically independent, and in that it carries out a complete analysis of the impact of information pooling on consumers and the society as a whole. In particular, by introducing new concepts such as the variation and allocation effects, we point out the possibility that the exchange of cost information is beneficial to Bertrand firms. Comparison with the more popular Cournot duopoly case is also made.
