Product market concepts from industrial organization economics are integrated with financial valuation models of the firm to investigate relationships among systematic risk, capital intensity, and product market power. The theory of the firm facing uncertain input and output prices is extended to provide empirical models. Empirical results coincide with hypotheses derived from the theoretical model and pose questions about traditional single period hypotheses found in the finance literature.  相似文献

With all the indications suggesting that the current imbalance between supply of and demand for grain will continue for the foreseeable future, and with a steady surplus both keeping prices down and forcing on governments measures to reduce output and stocks, attention is turning to South East Asia, a region which, due to the rapid growth of both its population and per capita income, seems to offer the best prospects of medium and long-term increases in demand. How realistic are the hopes that South East Asia will be able to absorb a substantial part of the world's grain surplus?  相似文献

This paper presents evidence on some of the key variables that have determined the economic status of different groups in the working population. Economic status is set by the level and security of real income and consumption. These are themselves determined by access to resources in the areas of the labour market, public services and social security, and in housing. The paper reviews the period between 1880 and 1990, and puts forward the likely situation in the year 2000. The century began with an agenda set by the problems of falling real incomes and poverty. It is likely to end with the problems of economic and demographic ageing as the main focus.  相似文献

This paper provides an analysis of the present situation concerning local government accounting in Spain following recent reforms introduced in the early nineties. It presents a picture of the main features of Spanish local finance—budgeting and accounting, the measurement focus, and the basis of accounting—and analyses the financial reporting system adopted by Spanish municipalities. This is followed by a critical review of several weak points in the reform which in the author's view will encourage further developments.  相似文献

Since measurement errors have strong effects in all relationships (statistical or otherwise) studied, there is an increasing interest in the data quality, which is the major justification for this research. This paper aims to present a new measurement procedure, the letter scale, which avoids many of the problems connected with the response modalities traditionally used in attitudinal research, especially the ordinal categorical scales. This paper analyzes the error composition of the scores obtained with this new measurement procedure. The validity of the procedure is also analyzed and the observed variance is assessed to determine which part of the observed variance is “valid”, which part is random error (attenuating relationships) and which is correlated error (magnifying relationships). Structural equation models will be used to provide estimates of the measurement quality: (i) Reliability, (ii) Construct validity, method effect and residual variance. In addition, this letter scale is evaluated under another different perspective, Information Theory measures are also used to assess the amount of information transmitted. The relative merits of this new measurement procedure as opposed to other common response modalities will be discussed in both cases.  相似文献

This article addresses the contribution to hedonic modeling of a nonparametric approach based on artificial neural network (ANN) regressions. ANNs provide consistent estimates for the hedonic price of each attribute and permit a number of hypotheses on the hedonic price relationship to be tested nonparametrically. In particular, we exploit results by Stinchcombe and White (Econom Theory 14:295?C324, 1998) in order to carry out misspecification testing in linear and semiloglinear hedonic models. The same approach directly applies to testing misspecification of any parametric specification for the hedonic relationship. A nonparametric significance test for the variables in the hedonic model is also proposed. The test extends the approach developed by Racine (J Bus Econ Stat 15(3):369?C378, 1997) in kernel-based nonparametric testing to ANN-based inference. The finite sample performance of the proposed tests is analyzed through Monte Carlo experiments, and simulation-based algorithms for computation of the null distribution of the tests are proposed. Then, the performance of three classes of regression models??linear, semi-log, and ANNs??applied to hedonic price modeling in a Spanish regional housing market is compared. Our results indicate the presence of nonlinear behavior, as predicted by economic theory, with the ANN-based tests detecting statistically significant evidence of misspecification??both in the linear and the semilog specifications??and ANN regressions providing moderate improvement of predictive performance.  相似文献

In the past 20 years a key topic of public-sector reform inOECD countries has been the emergence of regulatory policy.During this period, the nature of regulation has undergone profoundand rapid change. This paper reviews the development of regulatorypolicy in OECD countries over the last quarter-century. It identifiesa range of tools and institutions that have been used by OECDcountries to develop high-quality regulation. The analysis attemptsto show that while there is considerable commonality on broadobjectives of regulatory policy, considerably diversity remainsin the implementation of regulatory policy across OECD countries.
