Rethinking evidence-based policy

Much of public policy has in recent decades been driven by the idea of evidence-based policy – policy rooted in the principles of social science and, more specifically, empirical validation based on social and behavioural science. This article argues that evidence-based policy, while helping to improve the design of policies aimed at changing individual behaviour, lacks a recognition that individual and group choices are embedded in social relationships and institutions.

Understanding and Confronting Uncertainty: Revisions to UK Government Expenditure Plans

We develop a simple model that motivates fiscal stabilisation policy, in the presence of economic and control uncertainty. An examination of a real-time database of economic variables and forecasts shows that our knowledge of the current and future state of the economy is subject to significant revisions over time. Multi-year government spending plans are also significantly revised over successive fiscal events. We show the risk for any given government expenditure plan by constructing measures of historical expenditure revisions.

Modelling events: The short-term economic impact of leaving the EU

This paper presents a framework for modelling important socio-economic events in order to provide an informative counterfactual. This involves mapping the deep underlying shock associated with the event itself into a series of more tractable shocks consistent with the model being applied and calibrated from data, existing literature or ancillary analysis. The results should then be subject to testing of their sensitivity to the assumptions made.
