We propose a mechanism via which a decline in the share of young workers slows employment growth in expanding sectors, and exacerbates sectoral reallocation costs. To quantify this mechanism, we develop a search model with perpetual youth, three sectors and endogenous separations of worker-firm...

Why do some vacancies offer a posted wage whereas others offer a negotiable wage? The paper endogenizes the choice of wage policy in a search model with heterogeneous workers. In particular, we characterize the circumstances under which there exists an equilibrium where all firms negotiate...

An advantage of collective wage agreement is that search and business-stealing externalities can be internalized. A disadvantage is that it takes more time before an optimal allocation is reached because more productive firms (for a particular worker type) can no longer signal this by posting...

This paper analyses the emergence of the informal economy in the environment characterised by non-competitive labour markets with wage bargaining. We develop a simple extension of the standard search model à la Pissarides (2000) with formal and informal sectors to show how a government's...

A natural holdup problem arises in a market with search frictions: firms have to make a range of investments before finding their employees and larger investments translate into higher wages. In particular, when wages are determined by ex post bargaining, the equilibrium is always inefficient:...

There are large international differences in the gender pay gap. In some developed countries in 2010-2012, women were close to earnings parity with men, while in others large gaps remained. Since women and men have different average levels of education and experience and commonly work in...

Recent studies have pointed to the association between declining collective bargaining coverage and rising overall wage inequality. This association holds more or less across-the-board, at least for broad swathes of recent history. That said, the exact contribution of deununionization is a...
