Financial Market Imperfections, Labour Market Imperfections and Business Cycles

A Greenwald–Stiglitz (1993a) style rational expectations business cycle model is introduced in which uncorrelated productivity shocks or monetary shocks generate autocorrelated employment fluctuations due to financial constraints. The propagation mechanism is carefully modelled: because of capital market imperfections (only standard debt contracts are traded), firms' labour demand changes in response to changes in their balance-sheet position; because of labour market imperfections (efficiency wages), employment and unemployment fluctuate in response to shifts in labour demand. The virtue of the model is its simplicity. Despite the fact that unemployment is endogenous, the dynamic behaviour of the model under rational expectations can be characterised analytically.

Compulsory Schooling Laws and the Cure for Child Labour

This paper provides an explanation for the existence of child labour which relies on the imperfect enforcement of compulsory schooling laws. In the presence of complementarities in the production of human capital that justify legislative intervention, mandatory measures ensure that coordination failures are solved so that all parents send their children to school and the socially optimal equilibrium is reached. However, if enforcement of legislation is too low, multiple equilibria emerge. In this case, compulsory schooling laws may have adverse welfare effects on all households.     

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.     

Social Status,Labour Market Frictions and Endogenous Growth

This paper develops an endogenous growth model that incorporates wealth‐enhanced preferences for social status and labour market frictions to investigate the role of social status in determining unemployment and long‐run growth. We show that the increase in the desire for social status reduces the unemployment rate, but its effect on long‐run growth is unclear. We then calibrate our model to the US economy and find that an increase in the desire for social status lowers the unemployment rate and enhances the economic growth rate in the long run.     

Labour Demand, Wage Mark-ups and Product Market Integration

Globalization makes it easier to relocate production and thus employment across countries. Therefore, it is often asserted that labour demand becomes more elastic, causing wage mark-ups to fall and thus erode the effective market power of trade unions. We explore this issue in a general equilibrium model where the elasticity of labour demand is endogenized and related to the facility by which production can be relocated across countries. Wages and employment increase unambiguously as a result of product market integration, but it is ambiguous whether wage mark-ups decrease or increase. A numerical illustration suggests that the elasticity effect – even when the wage mark-up falls – is of second order relative to the gains from trade.      

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.     

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     

The Welfare State, Budgetary Pressure and Labour Market Shifts

Public debate about the welfare state in OECD countries has emphasized the need for reform to meet a twofold set of shocks: budgetary pressure and a labour market shift against unskilled workers. The aim of the paper is to set out a framework for examining the implications of these shocks for the optimal scale of social transfers and, in particular, the impact on different societies, distinguishing a restricted welfare state, labelled the United States and a more extensive welfare state, labelled Continental Europe.

Displacement Effects of Active Labour Market Policy: The Youth Labour Market in Finland

In 1994 the number of workers participating in active labour market programmes in Finland was 299,000. On average there where 125,000 workers in these programmes at any one time, the average length of participation in a programme being about 5 months. In relation to the 2.5 million-strong Finnish labour force, these figures are proportionally large. In 1994 the total expenditure on unemployment amounted to 6.7 per cent of GNP of which the share spent on active labour market programmes was about 25 per cent. The study investigates the displacement effects of active labour market programmes in the youth labour market in Finland. The two age groups analysed are 15-19-year-olds and 20-24-year-olds. The results, based on a VAR analysis of quarterly data from the period 1981.1-1995.2, suggest that the displacement effects of job-creation programmes may be substantial. The study cannot, however, provide any robust estimates of the likely size of such displacement effects on youth employment in Finland. This revised version was published online in July 2006 with corrections to the Cover Date.     

Market Rigidities and Labour Market Flexibility: An International Comparison

The effects of product and labour market rigidities on labour market dynamics are analysed using a panel of two-digit ISIC level data for seven OECD countries. As expected, employment protection was found to slacken labour market flows. Centralized wage bargaining also reduced the degree of job turnover, although a priori the effect of centralized wage bargaining on labour market flexibility is not clear. Industry subsidies have a positive impact on job reallocation by increasing job creation. The labour market dynamics are also compared in detail for two economies regarded as extremes in terms of regulations, the U.S. and Norway.     

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.

Family Income and Wealth,Youth Unemployment and Active Labour Market Policies

This paper studies some features of unemployment in Italy using cross section individual micro data. Since unemployment is particularly harsh with respect to youths, interest is focused on 15-29-year-old youngsters. The analysis is carried out using standard logit models and the results show that personal and family characteristics play an essential role in shaping youth activity and unemployment rates of short and long duration, together with product market conditions and labour market features. In particular, the income effect seems relevant for participation decisions, while the family wealth helps in reducing youth unemployment. Various policy instruments might be able to reduce youth unemployment, especially if these instruments are targeted through means-testing on family income and wealth and through a proper distinction between the first job seekers and the strictly unemployed.
