The share of renewable energies in the electricity sector ('green' electricity production) relative to overall electricity supply has been growing steadily over the last years in most industrialized countries. This expansion was due to economic support either by subsidies or quota requirements...

This paper aims at discovering the decision rule the Governing Council of the ECB uses to set interest rates. We construct a Taylor rule for each member of the council and for the euro area as a whole, and aggregate the interest rates they produce using several classes of decision-making...

A reliable prediction of unconditional welfare distributions, like income or consumption, is essential for welfare analysis, and in particular for inequality, poverty or development studies. Where observations of expenditures or income are missing, the mean prediction based on available...

This paper examines the costs of recent sovereign defaults using synthetic control methods, a novel econometric technique based on comparative case studies. Evidence on the effects of debt crises is thus presented on a case-by-case basis, uncovering large variations in country-specific...

In many cases, collusive agreements are formed by asymmetric firms and include only a subset of the firms active in the cartelized industry. This paper endogenizes the process of cartel formation in a numeric simulation model where firms differ in marginal costs and production technologies. The...

This paper revisits the trade-of between central bank independence and conservatism using a New Keynesian model with uncertainty about the central banker's output gap target. It is shown that when this uncertainty is high, the trade-of no longer holds. In this case, the optimal combination...
