In this paper I analyse the main strengths and weaknesses of agent-based computational models. I first describe how agent-based simulations can complement more traditional modelling techniques. Then, I rationalise the main theoretical critiques against the use of simulation, which point to the...

Multiplicative models of firm dynamics ‘à la Gibrat’ have become a standard reference in industrial organization. However, some unpleasant properties of their implied dynamics – namely, their explosive or implosive behaviour (firm size and number collapsing to zero or increasing...

The purpose of this note is to discuss the distributional effects of some a priori identified UBI schemes, as an illustration of the different trade-offs involved, and to foster the debate around UBI in France. All these schemes share the feature of retaining some limited form of targeting - in...

This paper uses the marked divergence in labour force participation trends between the US and the UK to probe underlying drivers and implications for recent US poor performance. Contrary to a common US narrative, our comparative perspective suggests that the relative decline in US labour force...

We nowcast the economic effects of the Covid-19 pandemic and related lock-down measures in the UK and then analyse the distributional and budgetary effects of the estimated individual income shocks, distinguishing between the effects of automatic stabilisers and those of the emergency policy...

We develop a new methodology to nowcast the effects of the COVID-19 crisis and forecast its evolution in small, export-oriented countries. To this aim, we exploit variation in financial indexes at the industry level and relate them to the expected duration of the crisis for each industry, under...
