Empirical Inference with Equilibrium Search Models of the Labour Market

This paper examines the use of equilibrium search models in the empirical analysis of labour markets. We survey the literature on structural estimation of these models with micro data on wages and durations, and we discuss the advantages of this approach for policy analysis and for obtaining a better understanding of the labour market. During the past ten years, substantial progress has been made in terms of the explanatory power of these models. We finish with a critical examination of the extent to which the approach can be fruitfully applied to (matched worker-) firm data.     

Labour Market Policies and Long-term Unemployment in a Flow Model of the Australian Labour Market

This paper develops a general equilibrium job matching model, which is used to assess the impact of active labour market policies, reductions in unemployment benefits and reductions in worker bargaining power on long-term unemployment and other key macro variables. The model is calibrated using Australian data. Simulation experiments are conducted through impulse response analysis. The simulations suggest that active labour market programs (ALMPs) targeted at the long-term unemployed have a small net impact and produce adverse spillover effects on short-term unemployment. Reducing the level of unemployment benefits relative to wages and worker bargaining power have more substantial effects on total and long-term unemployment and none of the spillover effects of ALMPs.     

基于劳动力市场分割的劳动力流动模型的构建

国内外学者对于劳动力流动进行了大量深入的研究,成果颇丰.然而,由于历史的原因,我国在劳动力流动方面呈现出与其他国家不同的特性,目前,我国的劳动力市场尚未发展成熟,劳动力流动存在很严重的不合理现象.因此,结合我国的现实情况对其进行研究意义更加重大.本文试图结合以往学者的研究成果,构建基于劳动力市场分割的劳动力流动模型,对其进行深入的探讨,为实现劳动力的合理流动提供帮助.     

The Labour Market and Inequality

Newspoll reported in 2000 that by a margin of 70 to 28 per cent, Australians would prefer the gap between rich and poor to get smaller rather than have the nation's overall wealth grow as quickly as possible. This article examines the reasons for the increase in the dispersion of earnings, and changes in unemployment and workforce participation, which are central to this concern about inequality. The major finding is that the widening dispersion of earnings and changes in labour force status are principally due to changes in the structure of labour demand in favour of more skilled jobs. The article then considers what this changing job mix implies for policy directed to maintaining income inequality.     

Efficiency and Equality in the Labour Market

I review theoretical arguments suggesting that certain labourmarket institutions can be justified for economic efficiencyreasons. In models with intrinsic market failures, "rigidities"like employment protection legislation and institutional wagecompression may push the economy closer to the efficient frontier.I discuss recent empirical evidence on income inequality, povertyand income mobility in OECD countries, and I conclude that thewelfare states of Northern Europe score relatively well on allcounts. Finally, I discuss labour market reforms that may improveefficiency without violating European voters' preference forequality.(JEL H30, J30, J50)     

Heterogeneous Jobs and the Aggregate Labour Market

This paper analyses a simple search‐and‐matching model with heterogeneous jobs. First, I derive an explicit formula that ensures the social efficiency of the equilibrium outcome. This formula generalises the well‐known Hosios condition and clarifies the role of externalities across labour markets for different types of jobs. Second, business cycle fluctuations with heterogeneous jobs are analysed. Heterogeneity in productivity and job stability plays an important role in generating strong labour‐market responses to productivity shocks.     

Compulsory Superannuation and Labour Market Responses

Compulsory contributions to superannuation have significant second round effects on labour market outcomes. The effects of employer, employee and government contributions are compared and contrasted for markets with different degrees of wage flexibility. With a flexible wage, the market wage adjusts to offset most of the initial effects of the superannuation levies. However, compulsion means that many employees perceive the present value of the future retirement income to be less than the levy. The levies as a form of tax on labour lead to lower overall remuneration for employees and lower employment     

Labour Market Flexibility and Immigrant Adjustment

A comparative analysis of adult male immigrant earnings and unemployment in the US and Australia using a measure of expected earnings shows that immigrants in the US perform relatively well, and the pattern of the differences between immigrant adjustment in the US and Australia appears to have links to differences in methods of pay determination. The results suggest an advantage to a more flexible labour market. A simulation exercise demonstrates the sensitivity of the findings to cohort effects.
