In statistics, samples are drawn from a population in a data-generating process (DGP). Standard errors measure the uncertainty in sample estimates of population parameters. In science, evidence is generated to test hypotheses in an evidence-generating process (EGP). We claim that EGP variation...

We study the effects of globalisation on the slope of the New Keynesian Phillips curve for CPI inflation, based on a broad panel of 35 countries and controlling for possibly non-linear exchange rate effects. We find that the output gap generally has a significant positive effect on inflation,...

Industrial activity periodically experiences breakthrough innovations in energy efficiency, but the estimated impacts of these innovations on aggregate energy use are highly varied. We develop a general equilibrium model to investigate whether this variation is determined by the structure of the...

Richard Musgrave was one of the around 200 academic economists who emigrated from Germany when Fascism came to dominate the country. This memorial lecture traces the German and European roots of Richard Musgrave's oeuvre, trying to shed light on his family background as well as on the political...

This paper develops a dynamic stochastic general equilibrium model to examine the quantitative macroeconomic implications of countercyclical fiscal policy for France, Germany and the UK. The model incorporates real wage rigidity which is the particular market failure justifying policy...

We derive exact conditions relating the distributions of firm productivity, sales, output, and markups to the form of demand in monopolistic competition. Applications include a new “CREMR” demand function (Constant Revenue Elasticity of Marginal Revenue): it is necessary and sufficient for...

We develop a model of optimal carbon taxation and redistribution taking into account horizontal equity concerns by considering heterogeneous energy efficiencies. By deriving first- and secondbest rules for policy instruments including carbon taxes, transfers and energy subsidies, we then...

In the Covid-19 crisis, most OECD countries have used short-time work (subsidized working time reductions) to preserve employment relationships. This paper studies whether short-time work can save jobs through stabilizing aggregate demand in recessions. First, we show that the consumption risk...
