Privatization, Labor and Social Safety Nets

Privatization promotes economic efficiency and growth, thereby reinforcing macroeconomic adjustment. In the short run, however, it can lead to job losses and wage cuts for workers. This paper discusses these adverse impacts of privatization in terms of various methods of privatization and surveys the existing empirical evidence. It finds that public sales and auctions can have stronger negative effects on workers but maximize the government's revenue. Policymakers' options for mitigating the social impact of privatization are surveyed.     

The History of the Dirichlet and Liouville Distributions

The Dirichlet distributions have long been the subject of intense scrutiny in statistics and probability. Despite the enormous interest in, and wide-ranging applications of, these distributions, little appears to be known about their history. In this article we review the development of the Dirichlet distributions and their companions, the Liouville distributions. After reviewing some integral formulas of Dirichlet and Liouville, we survey the theory and applications of these distributions in statistics.

Looking for voting paradoxes in Indian elections

We try to find out a methodology for identifying Borda Paradox and Condorcet Paradox in the absence of information on preference profile of citizens, and try to apply the same to find out existence of such paradoxes in the 2004 Indian Parliamentary elections.     

Forecasting inflation in an inflation targeting economy: structural versus nonstructural models

We propose a comparison between atheoretical and theoretical models in forecasting the inflation rate for an inflation-targeting country such as South Africa. In a pseudo real-time environment, our results show that for shorter horizons, the atheoretical error correction models, with and without factors, perform better; while for longer horizons, theoretical (Dynamic Stochastic General Equilibrium-based) models outperform their competitors.     

Portfolio behaviour of selected financial institutions in Canada

It is by now fairly well accepted that financial insititutions in general play role in a market-oriented economy. However,the aim of this paper is more limited. More particularty, it examines the nature of substitutability in the protfolios of selected financial institutions in Canada. The institutions covered are commercial banks, trust and mortgage companies, life insurance companies, and property and casualty companies. These four institutions are by far the most important. The assests covered are, in the most part, dictated by the availability of data. In spite of the obvious significance of the subject, there has been remarkably little work in this area in Canada. The only comprehensive study seems to be that by the Bank of Canada (Clinton and Masson, 1975). However, even this study is confined to the behaviour of commercial banks and the trust and mortgage companies, althouth the treatment of the trust and mortgage companies' portfolio is rather minimal only because just one of its assets is studied. The study covered monthly data until the end of December 1973. The scheme of this paper is as follows. In section I, we briefly discuss the model, the data and the estimation procedures used. In section II the results are given and discussed. The paper concludes with a summary of the main results.     

The many faces of pay variation

Research on pay variation and organizational outcomes has yielded inconsistent results. We argue that this is due to a lack of construct clarity regarding pay variation, and we attempt to provide clarification by distinguishing among the sources and types of pay variation. Using these distinctions, we integrate different theoretical perspectives on pay variation, and we propose avenues through which different kinds of pay variations affect outcomes. This clarification also elucidates some measurement concerns affecting pay variation studies.     

Optimal payout ratio under uncertainty and the flexibility hypothesis: Theory and empirical evidence

Following the dividend flexibility hypothesis used by DeAngelo and DeAngelo (2006), Blau and Fuller (2008), and others, we theoretically extend the proposition of DeAngelo and DeAngelo (2006) optimal payout policy in terms of the flexibility dividend hypothesis. In addition, we also introduce growth rate, systematic risk, and total risk variables into the theoretical model.To test the theoretical results derived in this paper, we use the data collected in the US from 1969 to 2009 to investigate the impact of the growth rate, systematic risk, and total risk on the optimal payout ratio in terms of the fixed-effect model. We find that based on flexibility considerations, a company will reduce its payout when the growth rate increases. In addition, we find that a nonlinear relationship exists between the payout ratio and the risk. In other words, the relationship between the payout ratio and the risk is negative (or positive) when the growth rate is higher (or lower) than the rate of return on total assets. Our theoretical model and empirical results can therefore be used to identify whether flexibility or the free cash flow hypothesis should be used to determine the dividend policy.     

Reaching customers at the base of the pyramid—a two‐stage business strategy

Two‐thirds of the world's population make less than $2,000 a year. There is increasing attention paid to how private firms can play a role in improving the quality of life of people at the bottom of the economic pyramid in ways that are mutually beneficial. But despite the promise of mutual benefit, many firms have not been able to serve very poor customers profitably. In this article, we present a two‐stage business strategy that will help firms to serve customers at the base of the pyramid. We suggest that in the first stage, firms need a deep cost management strategy, involving a focus on core customer value, and holistic operations reengineering. In the second stage, we suggest that firms need to consider a deep benefit management strategy, involving value reengineering, partnering for excellence, and creating inclusive channels. We support our ideas with examples of successful and unsuccessful cases of firms that have tried to serve the poor. © 2010 Wiley Periodicals, Inc.     

Housing and the Great Depression

This article considers the structural stability of the relationship between the real housing price and real GDP per capita for an annual sample that includes the Great Depression. We test for structural change in parameter values using a sample of annual US data from 1890 to 1952. The article examines the long-run and short-run dynamic relationships between the real housing price and real GDP per capita to determine whether these relationships experienced structural change over the sample period. We find that temporal Granger causality exists between these two variables only for subsamples that include the Great Depression. For the other subsample periods as well as for the entire sample period, no relationship exists between these variables.
