This study investigates the possibility of identifying those mutual funds in the Fidelity Family which might outperform the S&P 500 by using Jensen's alphas. An average of Jensen's alphas for a three-year period covering 1991–93 was computed and 1994 was used as a test case. A total of 152 Fidelity mutual funds were included in the study. Data were obtained fromAlexander Steele's Mutual Fund Expert Data Base [Steele Systems, Inc.] andHuntington Financial Optima Data Base [Huntington Associates Financial, Inc.]. It was found that it was possible to identify high performance funds. These funds had an alpha over 0.80. There were 21 funds in this group which produced an average total return of 4.44 percent, while S&P 500 had a total return of 1.32 percent in 1994.Any errors found in this paper are the sole responsibility of the author. The author would like to express sincere appreciation to Steele Systems, Inc. and Huntington Associates Financial, Inc. for providing the necessary data used in this study. Special appreciation also goes to Melissa Luo who so diligently and carefully performed all the computer work.  相似文献

This article discusses the valuable contribution that Ted Burczak's Socialism After Hayek makes to the Marxist theory of socialism by drawing on the Hayekian appreciation of markets as processes of discovery. But the article also critiques the book's acceptance of Hayek's exclusive reliance on markets as a mode of economic organisation. The article reflects on the methodological conditions that might have led the book down a path of market essentialism.  相似文献

This paper uses Degree Holders and Technical Personnel Survey of India to examine the wage gap between Non-Scheduled Castes/Tribes(NSC) and Scheduled Castes/Tribes(SC/ST). Separate wage equations, corrected for selection bias, are estimated for NSC and SC/ST. The parameter estimates of the wage equations were decomposed into ‘endowment’ and ‘treatment’ components using the familiar Oaxaca Decomposition Method. A separate account was also made to analyze the interaction between occupational attainment and the wage differential using the extended decomposition method. The main conclusion from the econometric results are: (a) the endowment difference is higher and discrimination causes 15 per cent lower wages for SC/ST as compared to NSC; (b) the discrimination coefficient is negative in the public sector whereas it is positive in the private sector; (c) intraoccupational wage effects dominate. The higher endowment difference in developing countries like India implies that the pre-market discriminatory practice with respect to education, health and nutrition are more crucial than labour market discrimination.

Abstract

Emil Lederer was characterized as the “leading academic socialist of Germany in the 1920’s” by Joseph Schumpeter and was a highly respected economist of his time. However, most aspects of his work remain totally unexplored. This paper focuses on Emil Lederer’s theory of economic fluctuations defending the thesis that certain aspects of Lederer’s conceptualization of economic fluctuations underwent considerable modifications when his 1925 article Konjunktur und Krisen is compared with his 1938 book Technical Progress and Unemployment, a shift unacknowledged so far in the literature. In his first attempt to tackle the issue, in Konjunktur und Krisen (1925), Lederer had constructed an explanation consistent with the so-called “disproportionality theory” introduced by Tugan-Baranowsky (codified as “early Lederer”). However, Lederer’s conception of the business cycle during the 1930s and especially in his major work Technical Progress and Unemployment underwent considerable modifications. Lederer’s (1938 Lederer, E. 1938. Technical Progress and Unemployment, Geneva: King and Son.  [Google Scholar]) analysis is, apparently, very ‘Schumpeterian’ (codified as “late Lederer”). In this version of his theory, the cycle is explained by supply-side factors, and more specifically by technical change. Additionally, Lederer’s view on the role of financial institutions (credit and banks) with regards to business cycles is analysed. Lederer avoided attributing a causative role to monetary factors. The interrelation between ‘real’ factors and financial institutions constitutes an essential element in his analysis of the business cycle.  相似文献

Britain’s education system was radically transformed during the 1990s following the Education Reform Act (1988). The primary objective of these reforms was to raise educational standards through the creation of a quasi–market based upon greater parental choice and the transfer of control over resources from local education authorities to schools. The purpose of this paper is to investigate the effects of the quasi–market on efficiency and equity in the secondary education sector in England during the 1990s. Two primary questions are addressed. Has the quasi–market led to an improvement in efficiency in the secondary education sector? Has the quasi–market had any adverse consequences on the social segregation of pupils between schools? Using data obtained from the Schools’ Census and the School Performance Tables, we find strong evidence that the quasi–market has led to a substantial improvement in efficiency (as measured by a school’s exam performance and by the productivity of staff) during the 1990s. The same market forces have led to a greater social segregation of pupils between schools.  相似文献

Gross job and worker flows in Russian industry are studied using panel data from a survey of 530 firms selected through national probability sampling. The data permit examination of several crucial measurement issues, including the timing and definition of employment and the role of reorganizations, and they contain rich information on firm characteristics. We find that new and reorganized firms display larger flows than unreorganized enterprises. Product market dispersion and managerial and dispersed outsider ownership are associated with greater worker churning, and unionization and concentrated outsider ownership with less. There is little evidence that the average firm's employment adjustments have become more responsive to adjustment costs during the transition, but private ownership and product market competition appear to increase responsiveness.

The favored approach in the literature on the growth prospects for transition economies is based on specifications from Barro (1991) and Levine and Renelt (1992). This paper examines this literature critically by identifying and testing for the underlying assumptions. Our main finding is that this approach performs poorly in the transition context. Our results indicate that, almost a decade after the transition began, the former centrally planned economies are still structurally different from market economies at similar levels of per capita income. The legacies of central planning are more resilient than previously thought. J. Comp. Econ., December 2001, 29(4), pp. 663–676.

We decompose real appreciation in tradables derived from producer price indexes in three Central European countries between the pricing‐to‐market component (disparity) and the local relative price component (the substitution ratio). Appreciation is only partially explained by local relative prices. The rest is absorbed by disparity, depending on the size of the no‐arbitrage band. The observed disparity fluctuates in a wider band for differentiated products than for commodity like goods.  相似文献

There is still some doubt about those economic variables that really matter for the Fed’s decisions. In comparison with other estimations, this study uses the approach of Bayesian model averaging (BMA). The estimations show that over the long-run inflation, unemployment rates and long-term interest rates are the crucial variables in explaining the Federal Funds Rate. In the other two estimation samples, also the fiscal deficit and monetary aggregates were of relevance. There is also evidence for interest rate smoothing. In addition, we account for parameter instability by combining BMA with time-varying coefficient (TVC) modelling. We find strong evidence for structural breaks. Finally, a model average is constructed via an TVC-BMA approach.  相似文献

笔者利用系综经验模式分解方法(EEMD)考察了股改启动前、股改期间与股改基本完成后上证综指与深证成指的波动结构特征及其变化。实证结果表明:与股改基本完成前相比,股改后我国股市的波动结构发生显著变化,即短期波动成分成为解释股市总体波动的最主要因素。同时,中期波动成分的平均周期大幅延长。股改后限售股大规模且集中解禁与减持对股市的冲击强化了市场的短线投机行为,引发股市短期波动急剧增加。而人民币升值、次贷危机等导致中期波动更具持久性。  相似文献

New market creation through transformation   总被引:1,自引:0,他引:1  
Is new market creation a search and selectionprocess within the theoretical space of all possible markets? Or is it the outcome of a process of transformation of extant realities into new possibilities? In this article we consider new market creation as a process involving a new network of stakeholders. The network is initiated through an effectual commitment that sets in motion two concurrent cycles of expanding resources and convergingconstraints that result in the new market. The dynamic model was induced from two empirical investigations, a cognitive science-based investigation of entrepreneurial expertise, and a real time history of the RFID industry.

Summary. In this paper a two sector dynamic general equilibrium model is developed in order to evaluate the implications of the underground economy from a business cycle perspective. There are three main results. First, introducing an underground sector improves the fit of the model to the data, especially along several important labor market dimensions. Second, the model produces substantial internal propagation of temporary shocks. Third, it is shown that underground activities offer risk sharing opportunities by allowing households to smooth income through a proper labor allocation between the two sectors.Received: 17 June 2002, Revised: 25 April 2003, JEL Classification Numbers: E320, E260, J22, H200.We have benefited from the comments and suggestions of John Donaldson. We would also like to thank Paolo Siconolfi, Jean Pierre Danthine, Fausto Gozzi, Edmund Phelps, Gustavo Piga, Domenico Tosato, and the participants in the seminars at various universities, David Giles and Stefano Pisani for providing useful information on the underground data, Francesca Caponi for the comments and the information concerning the legal and fiscal aspects involved in the calibration, and Glenn Williams for the research assistance. Finally, we thank two anonymous referees for helpful comments on this and on earlier versions of the paper.

We consider a situation in whichn firms located in market 1 andm firms located in market 2 each sell a commodity which is homogeneous within each market but may differ between markets. All firms sell on both markets. Each market has its own currency. The market demand functions differ. We give some basic results on the effects of exchange-rate changes and then show the following. When these markets are independent on the cost side (constant marginal costs) and demands are linear, a reduction in the number of firms (which might result from a merger) in market 1 increases the pass-through (of an appreciation of currency 2) in market 1 and decreases the pass-through in market 2. A similar occurrence in market 2 has the opposite effect. We give conditions under which, with identical economies of scope linking the markets, the sign of the price changes will be reversed when the number of foreign firms is small enough compared to the number of local firms. However, such sign reversals cannot occur in the two markets simultaneously.  相似文献

This article extends Kim's (1985 Kim, J-C. 1985. The market for lemons reconsidered: a model of the used car market with asymmetric information. American Economic Review, 75: 83643.  [Google Scholar]) model of the used car market with asymmetric information to examine the possible impacts of leasing and Certified Pre-Owned (CPO) programs on the average quality of traded used cars in the market. The author assumed that a consumer can buy or lease a new car, or he/she can buy a used or a CPO car. While, like Kim (1985 Kim, J-C. 1985. The market for lemons reconsidered: a model of the used car market with asymmetric information. American Economic Review, 75: 83643.  [Google Scholar]), the author assumed that the quality of a car depends on the maintenance level, the maintenance level in this model is chosen when a car is still a ‘new’ car, i.e. after the warranty ends. The model implied that the average quality of traded used cars can be either higher or lower than the average quality of nontraded used cars. The study also found that leasing and CPO have substantially improved the information mechanism between buyers and sellers of used cars, which, in turn, has helped reduce adverse selection and improved the average quality of traded used cars in the market.  相似文献

This article investigates fiscal convergence attained by EU countries in the period 1991–2008, by employing β‐ and σ‐convergence techniques complemented by a time series analysis. Overall our results highlight a distinctive convergence pattern in the European Union. Fiscal discipline leading to a fast convergence of deficit/GDP ratio over the 1990s markedly weakened in the following decade. Nonetheless, after the Euro debut a pronounced convergence in total revenue and total government spending emerges, with different patterns characterizing each expenditure component. Despite this evidence of fiscal harmonization, European treaties failed to attract countries toward a common share of government debt over GDP. (JEL E61, H11, C23)  相似文献

The dramatic rise in the ratio of Canada's average house price to average rent has led to speculation that there is a bubble in the Canadian housing market. Others have argued, however, that the currently high level of house prices may be rationalized by the low cost of financing, given the decline in interest rates over the last two decades. In this article, we assess these arguments through the lens of a simple asset pricing model applied to city‐level data. We quantify the extent to which excess growth in Canadian house prices depends on the nature of the current regime governing real interest rates, expectations of rent growth in different cities and variations in property taxes.  相似文献
