Booms, Busts, and Fraud

Firms sometimes commit fraud by altering publicly reported informationto be more favorable, and investors can monitor firms to obtainmore accurate information. We study equilibrium fraud and monitoringdecisions. Fraud is most likely to occur in relatively goodtimes, and the link between fraud and good times becomes strongeras monitoring costs decrease. Nevertheless, improving businessconditions may sometimes diminish fraud. We provide an explanationfor why fraud peaks towards the end of a boom and is then revealedin the ensuing bust. We also show that fraud can increase iffirms make more information available to the public.     

Supplements and Complements to the Current Employee Representation System in the United States

Employee representation is an important aspect of the employment relationship. In some countries (e.g., Germany), the government mandates employee representation. In other countries (e.g., the Commonwealth), employers voluntarily recognize employee representatives. In the United States, employees must earn their right to be represented in a certification process that results in collective bargaining. With the significant reduction of union membership in the United States, this representation model is in decline. Other forms of participation have not picked up the slack. Hence, there remains a significant representation gap. In this paper, I describe and analyze several solutions to the representation gap. Both unorganized and organized forms of employee representation are considered.     

A comparative study of performance appraisals,incentives and rewards practices in domestic and multinational enterprises in the country of Brunei Darussalam

Very little work in the past has focused on the comparative analysis of human resource management (HRM) practices between domestic and multinational enterprises (MNEs). The majority of the work in this area has instead concentrated on comparing the HRM practices utilised by the subsidiaries of MNEs, and has mostly been conducted in the context of developed countries. In this paper, we examine how the HR practices of appraisals, rewards and incentives are offered, explained and monitored in domestic enterprises (DEs) versus MNEs, and how they are similar or different in nature. This paper is based on primary data collected from a cross-section of firms operating in the country of Brunei Darussalam – a context within which no previous work of this nature has been undertaken. An analysis reveals several interesting results: HR practices are more advanced and better structured in MNEs that conduct performance appraisals (PA) more frequently than DEs, and their feedback system is also rapid; incentives and rewards systems in MNEs follow market ethos and principles; the HR directors and employees of MNEs are more receptive to PA than those in DEs whilst, in contrast to DEs, incentives and rewards systems in MNEs follow market ethos and principles. Furthermore, with regard to size, younger firms are more likely to be following market principles in terms of explaining incentives and rewards systems to their employees, whilst older firms claim that working for them carries social and psychological benefits for employees.     

Almost unbiased estimation in multiplicative models

In the lognormal linear models the estimation of constant term presents problems. In this paper we use weighted jackknife procedure (suggested by Hinkley 1977) for reducing the bias of the maximum likelihood estimator. The resulting estimator is unbiased upto order (1/T),T being the number of observations, and has the same MSE as that of the MLE to the same order of approximation; moreover, being the jackknife estimator it enjoys all the desirable large sample properties like any other jackknife estimator. The research of this author is partially supported through a research grant from NSERC of Canada.     

Equal Opportunities for Men and Women in the EU: A Commentary

This commentary examines the main objectives of the European Commission Fourth Medium-Term Action Programme on Equal Opportunities for Men and Women (1996–2000). An assessment is made of the objectives, and the methods proposed to achieve them.     

On the efficiency comparison of certain randomized response strategies

Comparisons between different randomized response strategies have already been performed by several workers but all have concentrated solely on comparing the variances of the appropriate estimators. A very little attention has been paid by these workers to the degree of privacy protection offered to the interviewees. In the present paper, an attempt has been made in this direction and some important randomized response strategies have been compared with the Warner's model, taking into account the aspect of privacy protection.

A test of the Wagner's hypothesis for the Fiji islands

In this article we examine Wagner's law for Fiji for the period 1970 to 2002. Using the Johansen (1988 Johansen, S. 1988. Statistical analysis of cointegrating vectors. Journal of Economic Dynamics and Control, 12: 231–54. [Crossref], [Web of Science ®] , [Google Scholar]) test for cointegration, we find one cointegration relationship between national output and government expenditure. Using five different long run estimators, we find robust results on the impact of national income on government expenditure. The elasticity ranges from 1.36 to 1.44, implying that a 1% increase in income leads to a 1.36–1.44% increase in government expenditure. Moreover, we find that in the long run national income Granger causes government expenditure. While these results are consistent with Wagner's law, we warn policy makers that because Fiji's total debt stands at around 69% of GDP, in future the bulk of expenditure will go towards debt financing at the expense of productive sectors.

On the generalization of Rao,Hartley and Cochran's scheme

Summary The problem considered in this paper is a generalization of the usual Rao, Hartley and Cochran (RHC) scheme. In the usual RHC scheme the population ofN units is randomly divided inton groups wheren is the size of the sample. In this paper we propose to divide the population under consideration into (n+k) random groups wherek is some positive integer. Then a sample ofn groups is selected by using simple random sampling without replacement (SRSWOR). The expressions for the unbiased estimator of population total, its variance and the unbiased estimate of variance have been obtained under the proposed sheme. The condition under which the proposed sheme is more efficient than the usual RHC scheme has also been investigated.     

Reinvestigating the Nature of Persistence of Shocks in the Macroeconomic Variables Relating to the Indian Economy with Special Reference to Structural Changes and Seasonality

Over the last two decades, there is a substantial debate on the persistence of shocks, in terms of their transitory and permanent nature, caused to the macroeconomic aggregates. Macroeconomic variables with transitory shocks will revert back to the long-run deterministic path eventually, whereas variables with permanent shocks will move according to random walk having no fixed predetermined path. These two series known as Trend Stationary (TS) and Difference Stationary (DS), respectively, have their significance in the specification of the regression equation and testing competing economic theories. Consequently there are a good amount of studies to classify the macroeconomic aggregates as TS vs. DS. In this context, relatively new developments of seasonal integration and presence of structural breaks in the macro variables has aroused a need to reinvestigate these hypotheses afresh. This paper makes an attempt to examine some of these issues by making use of the Indian data.
