Bayesian and Frequentist Inference for Ecological Inference: The R×C Case

In this paper we propose Bayesian and frequentist approaches to ecological inference, based on R × C contingency tables, including a covariate. The proposed Bayesian model extends the binomial-beta hierarchical model developed by K ing , R osen and T anner (1999) from the 2×2 case to the R × C case. As in the 2×2 case, the inferential procedure employs Markov chain Monte Carlo (MCMC) methods. As such, the resulting MCMC analysis is rich but computationally intensive. The frequentist approach, based on first moments rather than on the entire likelihood, provides quick inference via nonlinear least-squares, while retaining good frequentist properties. The two approaches are illustrated with simulated data, as well as with real data on voting patterns in Weimar Germany. In the final section of the paper we provide an overview of a range of alternative inferential approaches which trade-off computational intensity for statistical efficiency.     

Corporate Ethical Values and Altruism: The Mediating Role of Career Satisfaction

This study explores the ability of career satisfaction to mediate the relationship between corporate ethical values and altruism. Using a sample of individuals employed in a four-campus, regional health science center, it was determined that individual career satisfaction fully mediated the positive relationship between perceptions of corporate ethical values and self-reported altruism. The findings imply that companies dedicating attention to positive corporate ethical values can enhance employee attitudes and altruistic behaviors, especially when individuals experience a high degree of career satisfaction.     

The disclosure of key performance indicators in the public sector

This article investigates the disclosure of key performance indicators in the annual reports of Irish public sector organizations. It begins by discussing the two main driving forces behind public sector bodies disclosing performance information in their annual reports for the first time as well as looking at other contributing factors. The present situation with regard to the disclosure of key performance indicators in the whole of Ireland is then analysed. A number of annual reports from central government departments or agencies, local government bodies, other public sector entities and, in the case of the Republic of Ireland, semi-state organizations are examined to see whether such information is being disclosed and, more importantly, whether performance indicators are being linked to predetermined objectives and targets.

Would a stock by any other ticker smell as sweet?

Some stocks have meaningful ticker symbols; for example, LUV (Southwest Airlines), MOO (United Stockyards), and GEEK (Internet America). Such tickers might be a useful signal of the company's creativity, a memorable marker that appeals to investors, or a warning that the company feels it must resort to gimmicks to attract investors. This paper investigates the performance of stocks with memorable ticker symbols during the years 1984–2005 and finds that, on average, their daily returns are higher than for the overall market.     

Analysts' Earnings Forecasts and the Value Relevance of 20-F Reconciliations from non-U.S. to U.S. GAAP

This study extends existing research into the value relevance of reconciliations to U.S. GAAP by examining the role of analysts' earnings forecasts in explaining potential market reactions to the earnings reconciliation. One possible reason why the evidence on the value relevance of the earnings reconciliation is weak is that earnings are forecast by analysts. Their forecasts may pre-empt some of the information content of the earnings reconciliation disclosures. Our findings indicate that analysts' forecasts are value relevant and that they play a pre-emptive role for some firms. For others, however, the earnings reconciliation has information content that is not pre-empted by analysts' forecasts.     

A Cost Indirect Evaluation of Productivity Change in UK Universities

The study provides an empirical analysis of productivity change in publicly-funded UK universities, against a background of government policy specifically designed to enhance the productive efficiency of universities in the provision of teaching and research. The nonparametric analysis employs a cost indirect approach to measuring productivity change, taking explicit account of the quality of research output and decomposing productivity change into technical change and efficiency change. The latter is also decomposed into changes in pure technical efficiency, scale efficiency and output congestion. Changes in size efficiency are also computed. On average, productivity declined by 4% over 1989–92, mainly as a result of regressive technical change. Evidence of biased technological change was found, with the frontier shifting out in favour of the teaching outputs and in relative to the research output.     

Public policies,pressure groups,and dead weight costs

This paper presents a model of competition among special interest groups for political influence. Each active group exerts pressure to affect its taxes and subsidies, where activities of different groups are related by the equality between total tax collections and total tax subsidies. The dead weight costs and benefits of taxes and subsidies play a major role in our model. An increase in the dead weight cost of taxation encourages pressure by taxpayers, while an increase in the dead weight costs of subsidies discourages pressure by recipients. Various applications of the analysis are discussed.     

A Stochastic Frontier Analysis of Output Level and Growth in Poland and Western Economies

This paper uses Bayesian stochastic frontier methods to measure the productivity gap between Poland and Western countries that existed before the beginning of the main Polish economic reform. Using data for 20 Western economies, Poland and Yugoslavia (1980–1990) we estimate a translog stochastic frontier and make inference about individual efficiencies. Following the methodology proposed in our earlier work, we also decompose output growth into technical, efficiency and input changes and examine patterns of growth in the period under consideration.
