Human resource management in foreign-owned workplaces: evidence from Australia

Multinational companies have assumed a position of considerable prominence in the Australian economy. Drawing on the 1995 Australian Workplace Industrial Relations Survey, this paper examines the character of human resource management in multinational companies operating in Australia. The findings suggest that investments in the human resource function and the utilization of human resource practices were generally more widespread in foreign-owned than Australian establishments. This was especially the case for workplaces belonging to American and British-owned firms. It is concluded that the more strongly regulated industrial relations environment as well as the legacy of protected domestic markets have not made multinational companies reluctant innovators in human resource management in the Australian context.     

Computation of limiting distributions in stationarity testing with a generic trend

The asymptotic null distribution of the Lagrange Multiplier stationarity test, and analytical expressions for the limiting characteristic functions, are derived for a number of time series models which include a piecewise continuous deterministic trend. Some case studies illustrate the performance of the method.     

Comparing alternative tests of causality in temporal systems: Analytic results and experimental evidence

This paper discusses eight alternative tests of the absence of casual ordering, all of which are asymptotically valid under the null hypothesis in the sense that their limiting size is known. Their behavior under alternatives is compared analytically using the concept of approximate slope, and these results are supported by the outcomes of Monte Carlo experiments. The implications of these comparisons for applied work are unambiguous: Wald variants of a test attributed to Granger, and a lagged dependent variable version of Sim's test introduced in this paper, are equivalent in all relevant respects and are preferred to the other tests discussed.     

Unemployment and self-employment: a survey

The currently high level of unemployment emphasises the importance (in policy terms) of the potential contribution of a self employment alternative. Here the author examines the available UK evidence on the degree of movement from unemployment to self employment, the factors influencing this movement and the role of labour market information and training.     

Defense Spending and Unemployment Rates:

A bstract . Empirical evidence is provided, using vectorautoregressive techniques, that the employment impacts of defense spending are not equally distributed among racial and gender lines and across time. While increases in defense spending were generally found to be associated with increases in each of the unemployment rates , in the 1980s, it was observed that black males were most severely impacted by such spending, while white males were least severely impacted. It is hypothesized that this finding is consistent with a military industrial complex that has become increasingly complex and which focuses more on high tech weapons procurement than on personnel and maintenance concerns. In contrast, non-defense spending increases were associated with unemployment rate decreases in all categories. However, in terms of the distribution of these "favorable" impacts, white males benefitted the most and black males benefitted the least.     

Unemployment: Subsidies and Minimum Wages

The author outlines the 1981 'Youth Workers Scheme' he devised, and contends it was both successful and cheap. Minimum wages and wages councils are pernicious, the first ensuring that young people are priced out of hobs and the second leading to the suppression of competition.     

Kuhn-Tucker,likelihood ratio and Wald tests for nonlinear models with inequality constraints on the parameters

This paper considers the problem of testing statistical hypothesis in nonlinear regression models with inequality constraints on the parameters. First, the Kuhn-Tucker test procedure is defined. Next, it is shown that the distribution of the Kuhn-Tucker, the likelihood ratio and the Wald test statistics converges to the same mixture of chi-square distributions under the null hypothesis. To illustrate these results two examples are considered: (1) the problem of testing that individual effects are missing in an error component model, and (2) the problem of testing equilibrium for a model of markets in disequilibrium.     

Growth and Unemployment: Towards a Theoretical Integration

We observe in the literature of the past decade some innovative contributions identified a relation between economic growth and long run unemployment. This set of contributions is composed of very few elements, all characterized by a high degree of heterogeneity about their features and about their final results.
In the first part of the survey we provide a classification of these early contributions. In the second part we explore some alternative formulations of the problem and we present a wider set of models displaying interesting features, able to promote further studies about the persistence of unemployment in a growing economy.     

Detecting shocks: Outliers and breaks in time series

A single outlier in a regression model can be detected by the effect of its deletion on the residual sum of squares. An equivalent procedure is the simple intervention in which an extra parameter is added for the mean of the observation in question. Similarly, for unobserved components or structural time-series models, the effect of elaborations of the model on inferences can be investigated by the use of interventions involving a single parameter, such as trend or level changes. Because such time-series models contain more than one variance, the effect of the intervention is measured by the change in individual variances.We examine the effect on the estimated parameters of moving various kinds of intervention along the series. The horrendous computational problems involved are overcome by the use of score statistics combined with recent developments in filtering and smoothing. Interpretation of the resulting time-series plots of diagnostics is aided by simulation envelopes.Our procedures, illustrated with four example, permit keen insights into the fragility of inferences to specific shocks, such as outliers and level breaks. Although the emphasis is mostly on parameter estimation, forecast are also considered. Possible extensions include seasonal adjustment and detrending of series.     

Unemployment in East and West Europe

We use new 1991–2005 panel data to address the issue of unemployment in Central-East Europe. We compare the evolution of unemployment, its dynamics and related phenomena in five former communist economies in the Central Europe and use the geographically close West Germany as a benchmark for a mature market economy. We identify the differences and similarities in the evolution of the key labor market variables and contrast different outcomes with the diverse initial conditions and subsequent paths. All countries have experienced aggregate demand shocks, structural shocks and hysteresis. Despite diverse initial conditions and subsequent paths, the patterns observed are surprisingly similar. The eastern part of Germany appears to be a special case with extraordinary high unemployment inflows. Contrary to the theoretical models, in the transition economies we do not observe an initially rapid rise in the inflow rate, followed by a convergence of this rate to the levels of market economies. Rather, there is a relatively gradual rise in the inflow rate towards the level of market economies. The differences in unemployment rates turn out to be attributable to a considerable extent to the actual differences in the inflow rates. The trajectories in the unemployment-vacancy space observed in the Central-East European countries increasingly resemble those observed in the developed market economies. Interestingly, these similarities arise despite differences in the institutional setting across these economies.     

British Churches and Unemployment: Bias Against the Market

Bias to the Poor , a book by David Sheppard, the Bishop of Liverpool, outlines the familiar statist case for dealing with unemployment and relative deprivation but claims to be based on Christian principles. Robert Miller finds much of the thinking of the Church on unemployment ill-informed and shallow, its recommendations questionable on theological grounds, even shakier on economic issues, and lacking convincing analysis of the fundamental causes of unemployment.     

Regional Unemployment in Transitional China: A Theoretical and Empirical Analysis

The purpose of this paper is to explain the pattern of regional unemployment in transitional China. A model is developed to explore how urban unemployment in the provinces is influenced by peasants' wages, formal sector wages, and the size of the formal sector. Evidence from panel data suggests that a significant indicator of high unemployment rates is greater Urban–Rural Income Inequality within the province. The hypothesis is that the urban–rural income gap produces migration, and more rural migrants substitute for urban workers, causing further urban unemployment.Since the economic reforms began in 1978, the non-state owned enterprises have been carrying an increasing weight in the economy, and they have contributed significantly to the rapid economic growth of China. Empirical evidence shows that economic reforms have reduced unemployment. The provinces that are still heavily dependent on the state sector are therefore more likely to experience higher unemployment.     

Intergenerational Mobility in Britain: Evidence from Unemployment Patterns

Recent papers have examined the intergenerational transmission of well-being by looking at the relationship between parents' and children's income. However, by concentrating on those who are working these studies exclude some of the very poorest in society, the unemployed. In this paper we extend the empirical work on intergenerational welfare in the UK by looking at the links between fathers' and sons' unemployment histories. Using an approach which takes account of both incidence and intensity of son's unemployment, we provide further evidence showing that parental background is an important determinant of a child's future welfare. A son whose father was unemployed 20 years earlier is almost twice as likely to be unemployed as a son whose father was not unemployed. Furthermore, this dependency remains significant after controlling for a range of son's characteristics including education, ability and family composition.     

Breaking into Unemployment: The Black Economy and Workfare

Dr Graham Dawson, of the Employment Research Centre at University of Buckingham, sketches the reality of unemployment and the black economy. He describes how he helped carry out a survey of the unemployed in Liverpool in October 1986 and lost his car radio.     

Poverty and Mass Unemployment in Mineralrich Botswana

Abstract . The economic plight of Botswana's poor has worsened as a direct consequence of the mining sector's success. Their condition results from the process by which economic expansion and modernization has taken place. It has created an economic elite composed of a government bureaucracy and an emerging military “salariat,” and a small group of corporation officials and managers. The elite have joined white farming families as the country's largerscale land and cattle owners, purchasing land and cattle from savings out of relatively high salaries in the mining and public sectors. They have drilled boreholes for water and mechanized their farms and ranches. In effect, the elite have enjoyed access to the revenue from mining; their wealth is a product of that sector's growth, and the consequence is the emergence of a dual Botswana. One is rich, the other is poor, and the emerging clash between rich and poor could destabilize and threaten an African success story.
