Based on results from two causal identification approaches, we show that a higher rate of public-sector employment reduces volatility in, i.e. stabilizes, private-sector employment growth, with at most a slight crowding-out of private employment. Public wages, meanwhile, increase private wages but appear not to be destabilizing. The stabilizing effect of public employment with limited crowding out is at odds with standard search and matching models that contain a public sector, which predict 1:1 crowding out and strong destabilization. To improve the performance of such models, we follow <span>Gomes (2015)</span> and add a product market that can replicate what Gomes calls the Business Cycle Wealth Effect. We also point out that the government procures output directly from the private sector.

Our findings uncover the following key insights: (1) Changes in the level of search friction and/or the frequency of shocks on traders' preference type may lead to traders switching between high and low search intensities, shifting between the core and periphery of the trading network; and (2) Social optimality is achieved in the absence of intermediation, where no trader simultaneously invests in positive buying intensity and positive selling intensity.

Once at its optimal level, the replacement rate should vary counter-cyclically in response to demand shocks. Productivity shocks generate quasi-efficient fluctuations and call for a quasi-constant replacement rate.
