Severance Packages
Job-to-job turnover provides a way for employers to escape statutory firing costs, as unprofitable workers may willfully quit their job on receiving an outside offer, thus sparing their incumbent employer the firing costs. Furthermore, employers can induce their unprofitable workers to accept outside job offers that they would otherwise reject by offering voluntary severance packages, which are less costly than the full statutory firing cost. We formalize those mechanisms within an extension of the Diamond-Mortensen-Pissarides (DMP) matching model that allows for employed job search and negotiation over severance packages. We find that, while essentially preserving most standard qualitative predictions of the DMP model without employed job search, our model explains why higher firing costs intensify job-to-job turnover at the expense of transitions out of unemployment. We further find that allowing for on-the-job search markedly changes the quantitative predictions of the DMP model regarding the impact of firing costs on unemployment and employment flows: ignoring on-the-job search leads one to strongly underestimate the negative impact of firing costs on unemployment.firing costs, on-the-job search, mutual consent, minimum wage
On-the-job Search, Productivity Shocks, and the Individual Earnings Process
Individual labor earnings observed in worker panel data have complex, highly persistent dynamics. We investigate the capacity of a structural job search model with i.i.d. productivity shocks to replicate salient properties of these dynamics, such as the covariance structure of earnings, the evolution of individual earnings mean and variance with the duration of uninterrupted employment, or the distribution of year-to-year earnings changes. Specifically, we show within an otherwise standard job search model how the combined assumptions of on-the-job search and wage renegotiation by mutual consent act as a quantitatively plausible "internal propagation mechanism" of i.i.d. productivity shocks into persistent wage shocks. The model suggests that wage dynamics should be thought of as the outcome of a specific acceptance/rejection scheme of i.i.d. productivity shocks. This offers an alternative to the conventional linear ARMA-type approach to modelling earnings dynamics. Structural estimation of our model on a 10-year panel of highly educated British workers shows that our simple framework produces a dynamic earnings structure which is remarkably consistent with the data.job search ; individual shocks ; structural estimation ; covariance structure of earnings
The Public Pay Gap in Britain: Small Differences That (Don't?) Matter
The existing literature on inequality between private and public sectors focuses on cross-section differences in earnings levels. A more general way of looking at inequality between sectors is to recognize that forward-looking agents will care about income and job mobility too. We show that these are substantially different between the two sectors. Using data from the BHPS, we estimate a model of income and employment dynamics over seven years. We allow for unobserved heterogeneity in the propensity to be unemployed or employed in either job sector and in terms of the income process. We then combine the results into lifetime values of jobs in either sector and carry out a cross-section comparative analysis of these values. We have four main findings. First focusing on cross-sector differences in terms of the income process only, we detect a positive average public premium both in income flows and in the present discounted sum of future income flows. Second, we argue that income inequality is lower but more persistent in the public sector, as most of the observed relative cross-sectional income compression in the public sector is due to a lower variance of the transitory component of income. Third, when taking job mobility into account, the lifetime public premium is essentially zero for workers that we categorize as "high-employability" individuals, suggesting that the UK labor market is sufficiently mobile to ensure a rapid allocation of workers into their "natural" sector. Fourth, we find some evidence of job queuing for public sector jobs among "low-employability" workers.income dynamics ; job mobility ; public-private inequality ; selection effects

The Lifetime Earnings Premium in the Public Sector:The View from Europe
AbstractIn a context of widespread concern about budget deficits, it is important to assess whether public sector pay is in line with the private sector. Our paper proposes an estimation of differences in lifetime values of employment between public and private sectors for five European countries. We use data from the European Community Household Panel over the period 1994–2001 for Germany, the Netherlands, France, Italy and Spain. We look at lifetime values instead of wage levels because, as we show in our results, differences in earnings mobility, earnings volatility and job loss risk across sectors occur in many instances and these will matter to forward-looking individuals. When aggregated into a measure of lifetime value of employment in either sector, these differences yield estimates of the lifetime premium in the public sector for these five countries. We also present differences in the institutional and labour market structures in these countries and find that countries for which we estimate a positive lifetime premium in the public sector, i.e. France and Spain, are also the countries where access to the public sector requires costly entry procedures. This paper is to the best of our knowledge the first to use this dynamic approach applied to Europe, which we are able to do with a common dataset, time-period and model
Salaires et emploi dans les secteurs public et privé. Différences et interactions
Differences in wages and in employment between the public and the private sectors are not only present in a static comparison. Dynamic features of employment such as returns to experience, wage volatility and job security also exhibit differences across the two sectors. In the first part of this paper we document these differences in six European countries over the period 1994-2001 using the European Community Household Panel. This enables us to evaluate lifetime premia offered by public sector employment in these countries. In the second part of the paper we present a structural model of the labour market with a public sector, which allows us to quantify the response of the labour market as a whole to various public sector policies in terms of employment and wages. This structural approach enables us to assess and compare the potential impact of alternative polices aimed at reducing the public sector wage bill
