On measuring serial correlation: Implications for finance and accounting research studies

Accounting and finance studies that measure serial correlation implicitly make two assumptions. One, the studies assume that the sample estimate of the autocorrelation coefficient is unbiased. The assumption is intuitively appealing, but incorrect. This article provides a measure of the size of the bias. Two, the studies assume that the target of the time series is constant over time. However, over a long period target values may change. This article models the general case in which not only do random shocks affect actual values, but also random changes affect target values.     

Generational Accounts for The Netherlands: An Update

This paper extends the standard generational accounting methodologyby incorporating prospective changes in the economic environment,assigning the benefits of government purchases to generations,distinguishing between public consumption and public investment,and transforming the generational accounts into government budgets.It applies the methodology to the Netherlands. An expected increasein labor-force participation almost offsets the adverse effectof aging on the sustainability of the Dutch public finances.Since the rise in labor-force participation occurs before thebulk of the aging, the government will have to run sizable fiscalsurpluses in the next decades in order to create the budgetaryroom for higher age-related government expenditures in laterdecades.     

MORE COSTLY OR MORE PRODUCTIVE? MEASURING CHANGES IN COMPETITIVENESS IN MANUFACTURING ACROSS REGIONS IN CHINA

Using a newly constructed industry-by-region dataset based on China's two censuses, this paper examines the trend of average labor compensation (ALC), labor productivity (ALP) and unit labor cost (ULC) in 28 manufacturing industries across 29 provinces in China for 1995 and 2004. Findings show that at the aggregate level, ALP growth was generally faster than that of ALC and hence resulted in a significant decline in ULC for all regions in China. Furthermore, less developed regions exhibited stronger productivity growth relative to labor cost increase than more developed regions, thus leading to a convergence in ULC levels across provinces and regions over this period. Comparing individual industries, we observe a substantial variation in growth rates and convergence trends across regions. Logit regression analysis confirms that labor-intensive industries are more likely to converge in ALP, ALC and ULC, whereas capital/skill-intensive industries tended to diverge. This finding is further confirmed by estimating a convergence regression, which suggests that misallocation of resources due to market imperfections or institutional barriers is likely to be the main factor behind the divergence of ULC.     

Knowledge as Work: Conflicts in the Management of Knowledge Workers

Against the backdrop of increasing interest in knowledge management and intellectual capital, this paper analyzes the emergence and management of knowledge worker groups. It suggests that knowledge work is a useful way of characterizing some important changes in the nature of work across a range of different occupational and professional groups. These changes have important implications for management and organizational performance. The paper discusses these implications through a conflictbased analysis which highlights the inherent conflict between 'knowing' as part of the work experience and 'knowledge' as an economic commodity. This conflict is expressed at both institutional and organizational levels. The management of knowledge workers therefore centres on the quasi-resolution of such conflict. As the illustrative example of the Microsoft Corporation indicates, competitive success depends very largely on the precarious ability to reconcile this conflict between the social production of knowledge and the economic appropriation of profit.     

Reducing Structural Dominance and Entry Barriers in Russian Industry

While many industrial firms in Russiahave undergone ownership change, relatively few havecompetitively restructured. This paper, using survey and other data, suggests much of Russian industry is immune from robust competition due to seller/buyer concentration in select markets, a high degree of vertical integration, and geographic segmentation. Regulatory constraints protect incumbent firms from entrants, both domestic and foreign. The absence of new businesses is striking. Restructuringanti-competitive structures and reducing barriers to entry should be key items in Russia'spost-privatization program, and the paper sketches out a reform agenda. The nascent rules-based framework for competition policy should be strengthened to reduce discretion, increase transparency and enhance accountability.     

Do women react differently to incentives? Evidence from experimental data and payroll records

We consider the response to incentives as an explanation for observed productivity differences within a firm that paid its workers piece rates. We provide a framework within which the observed productivity differences can be decomposed into two parts: One due to differences in ability and the other due to differences in the response to incentives. We apply this decomposition to male and female workers from a tree-planting firm in British Columbia, Canada. Our evidence (both experimental and nonexperimental) suggests that there was no difference in the reaction to incentives between male and female planters. The productivity differential male planters enjoyed arose because of differences in ability, interpreted as strength in our application.     

The demand for pay service on cable television

A probability model is developed for consumer choice among three television programming options, free over-the-air television, basic cable television service, and pay cable serve which consists of basic service plus a single channel of premium entertainment programming. Estimating equations for the demand for pay service are derived from the probability model and then estimated by applying regression techniques to data from a large sample of U.S. cable systems. The estimated parameters of the demand equation show that the demand for pay service is affected by the prices charged for both basic and pay service, by demographic characteristics of the households served by a cable system, and by the quality of programming offered on both basic and pay services. The demand estimates suggest that the introduction of pay service has substantially enhanced the likelihood of profitable operation for cable systems in major television markets.     

An empirical model of the multi‐unit,sequential, clock auction

We construct a model of participation and bidding at multi‐unit, sequential, clock auctions when bidders have multi‐unit demand. We describe conditions sufficient to characterize a symmetric, perfect‐Bayesian equilibrium and then demonstrate that this equilibrium induces an efficient allocation. We propose an algorithm, based on the generalized Vickrey auction, to calculate the expected winning bid for each unit sold. This algorithm allows us to construct a simulation‐based estimator of the parameters for both the participation process and the distribution of latent valuations. We apply our method to data from 37 multi‐lot, sequential, English auctions of export permits for timber held in Russia. Copyright © 2006 John Wiley & Sons, Ltd.
