The State of Accounting and the State of the State

The purpose of this paper is to present a study of the evolution of accounting regulation within one country in the context of that country's historical development, the origins and motivations of the legal system and the state, and the subsequent outcomes in terms of accounting rules and regulations. The case in point is Greece. However, the paper neither describes specific regulatory practices in a systematic manner nor rules that exist for the preparation of the financial statements. It is concerned instead with the relationship between the state and corporate accountability.In the context of accounting regulation, Greece has recently attracted attention in the research literature. Papas (1993) and Ballas (1994) were among the first to describe to an international academic audience various institutional aspects of corporate accounting in Greece while Neal (1997) has attempted to describe the social and economic forces that have shaped its development. However, this study offers new insights into the institutional framework of accounting and in particular the relationship of the state to accounting regulation.     

A Necessary Power Divergence Type Family Tests of Multivariate Normality

In a recent article, Cardoso de Oliveira and Ferreira have proposed a multivariate extension of the univariate chi-squared normality test, using a known result for the distribution of quadratic forms in normal variables. In this article, we propose a family of power divergence type test statistics for testing the hypothesis of multinormality. The proposed family of test statistics includes as a particular case the test proposed by Cardoso de Oliveira and Ferreira. We assess the performance of the new family of test statistics by using Monte Carlo simulation. In this context, the type I error rates and the power of the tests are studied, for important family members. Moreover, the performance of significant members of the proposed test statistics are compared with the respective performance of a multivariate normality test, proposed recently by Batsidis and Zografos. Finally, two well-known data sets are used to illustrate the method developed in this article as well as the specialized test of multivariate normality proposed by Batsidis and Zografos.     

Stochastic volatility demand systems

We address the estimation of stochastic volatility demand systems. In particular, we relax the homoscedasticity assumption and instead assume that the covariance matrix of the errors of demand systems is time-varying. Since most economic and financial time series are nonlinear, we achieve superior modeling using parametric nonlinear demand systems in which the unconditional variance is constant but the conditional variance, like the conditional mean, is also a random variable depending on current and past information. We also prove an important practical result of invariance of the maximum likelihood estimator with respect to the choice of equation eliminated from a singular demand system. An empirical application is provided, using the BEKK specification to model the conditional covariance matrix of the errors of the basic translog demand system.     

Immigrant Populations and the Labour Market in Greece at the Beginning of the Twenty‐First Century

Our purpose in undertaking this research is to methodically map the labour market circumstances of the main immigrant groups in Greece. We classify all of the Districts of Greece into three categories (Diverse, Mixed and Unmixed) according to the ethnic composition of each District. We measure how the employment status of the immigrants varies (1) according to the ethnic group and sex of the immigrant, and (2) according to the ethnic composition and economic structure of a District. In general, the majority of immigrants exhibit lower unemployment and higher economic activity rates than the indigenous Greeks. Three immigrant groups (Albanians, Bulgarians and “Other”), which make up two‐thirds of the foreign‐born population of Greece, have lower unemployment rates than the national average, and lower rates than Greeks as well. The poorest labour market outcomes are observed in Unmixed and Mixed Districts, whereas Diverse Districts are better off. At the regional level, the most disadvantaged Geographical Department is the Ionian Islands, since it presents the highest unemployment rates for the general population for both sexes. With regard to sex‐differential unemployment across immigrant groups, we found that women exhibit higher unemployment than men in almost every ethnic group.     

Errors of misclassification in discrimination with data from truncated <Emphasis Type="Italic">t</Emphasis> populations

The distribution of the probabilities of misclassification is derived in this paper, which are reproduced by the use of the linear discriminant function. The statistical background is two independent doubly truncated t populations with distinct location parameters and common scale parameter and degrees of freedom. The behavior of the linear discriminant function is studied by comparing the distribution function of the errors of misclassification under the truncated t and truncated normal models.     

On the Harris extended family of distributions

A new method for generating new classes of distributions based on the probability-generating function is presented in Aly and Benkherouf [A new family of distributions based on probability generating functions. Sankhya B. 2011;73:70–80]. In particular, they focused their interest to the so-called Harris extended family of distributions. In this paper, we provide several general results regarding the Harris extended models such as the general behaviour of the failure rate function. We also derive a very useful representation for the Harris extended density function as an absolutely convergent power series of the survival function of the baseline distribution. Additionally, some stochastic order relations are established and limiting distributions of sample extremes are also considered for this model. These general results are illustrated in several special Harris extended models. Finally, we discuss estimation of the model parameters by the method of maximum likelihood and provide an application to real data for illustrative purposes.     

Monetary aggregation and the neutrality of money

This article tests the long-run neutrality of money proposition using quarterly U.S. data over the period from 1960:1 to 1996:2 and the methodology suggested by King and Watson (1997), paying particular attention to the integration and cointegration properties of the variables. Comparisons are made among simple sum, Divisia, and currency equivalent (CE) monetary aggregates using the Anderson et al. (1997a, 1997b) series of Divisia and CE monetary aggregates.
