我国商业银行规模经济评价方法研究

现有的关于银行规模经济评价的理论,要么基于参数法,要么专注于非参数法,很少有将二者兼顾考虑的评价方法.本文在充分考虑参数法和非参数法利弊的基础上,针对我国商业银行的特点提出了分类规模经济评价的思想.同时在利用DEA方法获得生产可能性集前沿面的基础上,建立了通过拟合生产函数获得各种规模经济评价指标的方法.     

我国商业银行规模经济问题与金融改革策略透析

本文通过对中国商业银行 1 994— 2 0 0 0年的经营情况的实证分析 ,估算出了各大银行的成本 -规模弹性。在此基础上 ,本文指出 :商业银行经营过程中长期存在的不良贷款沉淀以及放款上的所有制偏好等问题已成为现阶段影响我国金融机构成本 -规模弹性的重要因素 ,而隐藏于它们背后的产权制度安排上的缺陷、金融领域的长期垄断 ,以及民营银行的“国民待遇”等问题则应成为下一步改革的关键     

Estimating Scale and Scope Economies with Fourier Flexible Functional Form – Evidence from Taiwan's Banking Industry

In this study the scale and scope economies for Taiwan's banking sector using panel data from 22 domestic banks for the period 1981–1997 is investigated quantitatively using both a Fourier flexible functional form, first proposed by Gallant (1981, 1982), and a translog function. This study's results favour the use of the former, based on tests of regression coefficients and on estimates of various economy measures. The Fourier evidence shows that only smaller banks exhibit increasing returns to scale, while larger banks exhibit decreasing returns to scale. Conversely, the translog indicates that all the sample groups continue to enjoy economies of scale. Banks in Taiwan exhibit scope diseconomies, which suggest that sample banks should continue efforts to diversify their financial products, which in turn could substantially reduce their average costs.     

POVERTY IN POLAND, 1978–88

This paper considers the issue of poverty in Poland in the decade 1978–88, during which the Polish economy experienced a severe slump (1979–81), and started a modest recovery (1983–88). The estimated poverty rate increased from less than 10 percent of the population in the late 1970s to about 18–20 percent ten years later. The increase was almost entirely due to pauperization of the urban (workers and pensioners) households. As real wages decreased, the percentage of the poor workers' households increased from 6 to almost 20 percent. The total number of pensioners, a social group with the highest poverty incidence, went up due to demographic trends and government policy of early retirement in response to market reforms undertaken in 1982–83. In addition, poverty incidence among pensioners increased to 25 percent. Overall, out of the total estimated number of 7 million poor, about 3.1 million are the new poor, i.e. people who before the crisis lived above the poverty level, and have since fallen below it. Such a deterioration in living standards, to a large extent limited to urban areas, probably had a significant impact on the ever growing disenchantment with the Communist regime which eventually resulted in its overthrow.     

规模经济与银行业发展综述

规模经济既是西方微观经济学中的一个基本概念,也是产业组织理论研究的核心问题之一。银行业天生就是一个规模经济效应较强的产业。在研究中国银行业的规模经济问题时,重在探析决定和影响中国银行业规模经济的主要因素以及区分不同的层次;在关注银行规模内在经济和外在经济的同时,须考察银行规模结构,从静态和动态两方面去研究生产要素在银行间的配置组合格局。     

Excess Entry in the Absence of Scale Economies

It is well-known that with free entry, more firms than is socially optimal typically enter provided there are economies of scale. This paper investigates the possibility of excess entry in the absence of scale economies We thank Simon Anderson, Tom Holmes, the late Arijit Mukherji, and Xavier Vives for helpful comments. We also thank the participants at the July 2001 Australasian Meetings of the Econometric Society in Auckland, June 2002 University of Melbourne-National University of Singapore Symposium and seminar participants at the University of Sydney and University of New South Wales for useful suggestions. We are especially thankful to an anonymous referee whose meticulous comments have helped us to improve the paper     

Sources of Australian Labour Productivity Change 1950–1994

This study examines sources of Australian labour productivity change from 1950 to 1994. Time-series data are used to estimate a model capturing the interaction between labour productivity, fixed capital, human capital, telecommunications, trade openness and international competitiveness. Attention is given to the time-series properties of these data. ADF tests for unit roots are employed, and the sensitivity of the tests to non-linear transformations and structural breaks are considered. Estimates suggest that policies that promote investment, economic integration and international competitiveness will improve short-run labour productivity. In the long run, fixed capital accumulation is the dominant source of productivity improvement.     

Canadian manufacturers' relative productivity performance, 1907–1990

In this paper I calculate TFP ratios for a sample of Canadian manufacturers relative to their American counterparts on an annual basis throughout most of the twentieth century. The data used to calculate these ratios are drawn from both industry-level and firm-level statistical sources. I find that, in contrast to the relative labour productivity evidence in the literature, when TFP is used as the measuring stick, there is virtually no evidence of consistent and substantial relative technical inefficiency on behalf of the Canadian manufacturers represented in my sample. JEL Classification: D24, N60
Dans ce mémoire, l'auteur calcule les ratios de la productivité totale des facteurs de production (PTF) des manufacturiers canadiens par rapport à celle de leurs collègues américains sur une base annuelle pour la plus grande partie du vingtième siècle. Les données utilisées sont tirées des sources statistiques tant au niveau de l'industrie que de l'entreprise. On montre que, contrairement à ce que suggère la littérature spécialisée à propos de la productivité relative du travail, quand la PTF est utilisée comme étalon de mesure, on ne trouve vraiment pas vraiment de résultats qui suggéreraient une inefficacité technique relative substantielle et persistante des manufacturiers canadiens de l'échantillon.     

External Economies of Scale and Optimal Plant Location

This paper departs from earlier work on location theory by introducing external economies of scale into the Weber–Moses location model. It is shown that under Cournot–Nash competition, when external economies prevail, constant returns to scale at the firm level is not a sufficient condition for ensuring the invariance of the firm's optimal location with respect to a change in market demand, regardless of whether or not free entry is allowed. Moreover, when free entry is allowed and the production function exhibits decreasing returns to scale, but with very strong external economies, the optimal location moves towards or away from the market as demand increases according to whether the demand function is convex or concave. These results are different significantly from the conventional wisdom.     

International Inequality and Convergence in Educational Attainment, 1960–1990

The paper examines the international inequality and convergence of educational attainment from 1960 to 1990. Despite the increasing trend in educational attainment, the gap in educational attainment between the developing countries and developed countries and that between males and females increased in the period. However, the relative dispersion of educational attainment—as measured by the coefficient of variation, the Gini coefficient, or the standard deviation of log average years of schooling—declined consistently during the period by either development or gender status. Decompositions of the Gini coefficient indicate that the development gap and the gender gap were the main components for world inequality in educational attainment in both 1960 and 1990. Educational attainment exhibited b - and s -convergence over the period.
