The paper uses a neoclassical production function and historical data to test for structural stability in Australian manufacturing industry. The production function is an extended constant elasticity of substitution form in which factor substitution elasticity, returns to scale and market structure in output, capital and labour are testable hypotheses. Tests for structural changes in homogeneity and factor substitution elasticity relations are based on overall and individual tests of covariance analysis and also on a special version of the Swerling-Kalman filtering systems as proposed by Cooley and Prescott. The empirical findings possess desirable statistical properties and indicate the existence of structural instability in the industry. The evidence also repudiates the assumptions of unitary factor substitution elasticity, constant returns to scale and market competitiveness in output and factors of production.  相似文献

Summary ABRAHAM DE MOIVRE (1667 Vitry - 1754 London) was one of the foremost pioneers in the domain of the theory of probability. His principal contributions are laid down in his “Doctrine of Chances” (three editions, 1718, 1738, 1756). This classic work, almost forgotten, is now republished, as a splendid photographic reprint of the third (last) edition, by Chelsea Publishing Company of New York (1967). In this article we specially mention his original contributions respecting the problem of the duration of play, the theory and application of recurrent series, the theory of runs, and especially his extension of the value of BERNOULLI'S theorem by the aid of STIRLING'S theorem. In the last mentioned research DE MOIVRE obtained the equation for the curve of error, thus antedating LAPLACE by about 50 and GAUSS by 76 years. This important fact is discovered by KARL PEARSON in 1924.  相似文献

Over the past two decades, foreign banks have become much more important in domestic financial intermediation, heightening the need to understand their behavior. We introduce a new, comprehensive database, made publicly available, on bank ownership (including the home country of foreign banks) for 5,324 banks in 137 countries over the period 1995–2009. We document large increases in foreign bank presence in many countries, but with substantial heterogeneity in terms of host and banks’ home countries, bilateral investment patterns, and bank characteristics. In terms of impact, we document that the relation between private credit and foreign bank presence importantly depends on host country and banks’ characteristics. Specifically, foreign banks only seem to have a negative impact on credit in low‐income countries, in countries where they have a limited market share, where enforcing contracts is costly and where credit information is limited available, and when they come from distant home countries. This shows that accounting for heterogeneity, including bilateral ownership, is crucial to better understand the implications of foreign bank ownership.  相似文献

We propose a new definition of skill as general cognitive ability to pick stocks or time the market. We find evidence for stock picking in booms and market timing in recessions. Moreover, the same fund managers that pick stocks well in expansions also time the market well in recessions. These fund managers significantly outperform other funds and passive benchmarks. Our results suggest a new measure of managerial ability that weighs a fund's market timing more in recessions and stock picking more in booms. The measure displays more persistence than either market timing or stock picking alone and predicts fund performance.  相似文献

We propose a model of dynamic investment, financing, and risk management for financially constrained firms. The model highlights the central importance of the endogenous marginal value of liquidity (cash and credit line) for corporate decisions. Our three main results are: (1) investment depends on the ratio of marginal q to the marginal value of liquidity, and the relation between investment and marginal q changes with the marginal source of funding; (2) optimal external financing and payout are characterized by an endogenous double‐barrier policy for the firm's cash‐capital ratio; and (3) liquidity management and derivatives hedging are complementary risk management tools.  相似文献
