This paper investigates equilibria in a labor market where firms post wage/tenure contracts and risk-averse workers, both employed and unemployed, search for better paid job opportunities. Different firms typically offer different contracts. Workers accumulate general human capital through...

Workers might change jobs for many reasons. They might fall out with the boss and so decide to change employer, or learn that the job is not really for them, or they might accept a poorly paid job as being preferable to being unemployed - say gathering work experience improves one's CV - and...

The focus of this chapter is to consider new developments in the search and matching literature where wages, quit turnover and unemployment are endogenously determined in economies with aggregate shocks. The aim of the discussion is not only to highlight possible market failures but also to...

In this paper we develop and quantitatively assess a tractable equilibrium search model of the labour market to analyse the long-term wage costs of a job loss. In our framework, these costs occur due to losses in workers' human capital and firm specific compensation, interruptions to workers'...

This paper develops a new equilibrium model of two-sided search where ex-ante heterogenous individuals have general payoff functions and vectors of attributes. The analysis applies to a large class of models, from the non-transferable utility case to the collective household case with...

This paper develops and estimates a fully microfounded equilibrium business cycle model of the US labor market with aggregate productivity shocks. Those microfoundations are consistent with evidence regarding the underlying distribution of firm growth rates across firms [by age and size] and,...

We investigate what happens when the fiscal authorities do not react to rising public debt so that the unpleasant task of fiscal sustainability falls upon the Central Bank (CB). In particular, we explore whether the CB's bond purchases in the secondary market can restore stability and...

Calculations based on the intertemporal government budget constraint can be only indicative regarding an economy's fiscal sustainability. Sovereign interest rates, growth rates, as well as primary fiscal balances are all endogenous variables that are jointly determined. This rationalizes the use...

We develop an endogenous growth model to quantify how permanent structural policy changes that enhance the fiscal policy mix, markets' functioning, and public institutions' quality affect long-term growth and welfare. The reforms include increased public investment, reduced market power through...

We reconsider the conventional wisdom that, in the presence of public goods and distortionary taxation, Nash tax rates are inefficiently low due to free riding. We use a model in which the public good is natural resources. Specifically, a general equilibrium model of a world economy, in which...
