The public sector hires disproportionately more educated workers. To rationalize this finding, we propose a model with a perfectly competitive private sector, and non-Walrasian public sector. Our economy also features heterogeneity across individuals and jobs, and a simple sorting mechanism that...

We propose a simple theory of under- and over-employment. Individuals of high type can perform both skilled and unskilled jobs, but only a fraction of low-type workers can perform skilled jobs. People have different non-pecuniary values over these jobs, akin to a Roy model. We calibrate two...

In the US almost 3 per cent of employees are absent from their job for reasons other than vacation, but are still technically employed. We argue that firms may find optimal to use temporary replacement workers to fill these vacant positions. We set up a matching model with directed search and...

In this paper I use the Labour Force Survey to obtain stylised facts about worker gross flows in the United Kingdom. I analyse the size and cyclicality of the flows between employment, unemployment and inactivity. I also examine job-to-job flows, employment separations by reason, flows between...

I build a dynamic stochastic general equilibrium model with search and matching frictions and two sectors in order to study the labour market effects of public sector employment and wages. Public sector wages plays an important role in achieving the efficient allocation. High wages induce too...

This paper documents a number of facts about worker gross flows in the United Kingdom for the period between 1993 and 2010. Using Labour Force Survey data, I examine the size and cyclicality of the flows and transition probabilities between employment, unemployment and inactivity, from several...
