Inflation has been persistently weak in the euro area despite the economic recovery since 2013. We investigate the sources behind this protracted low inflation by building a time-varying parameter model that jointly explains the dynamics of inflation and inflation expectations from the ECB's...

Should the central bank seek to identify the underlying causes of oil price hikes in determining appropriate policy responses to them? Most likely not. Within a calibrated new-Keynesian model of Oil-Importing and Oil-Producing Countries, I derive the Ramsey policy and analyze optimal monetary...

This paper considers the interdependence of monetary and macroprudential policy in a New Keynesian business cycle model under the zero lower bound constraint. Entrepreneurs borrow in nominal terms from banks and are subject to idiosyncratic default risk. The realized loan return to the bank...

This paper studies the behaviour of firm entry and exit in response to macroeconomic shocks. We formulate a dynamic stochastic general equilibrium model with an endogenous number of producers. From the calibrated model, we derive a minimum set of robust sign restrictions to identify four kinds...

Rational expectations models fail to explain the disconnect between the exchange rate and macroeconomic fundamentals. In line with survey evidence on the behaviour of foreign exchange traders, we introduce model misspecification and learning into a standard monetary model. Agents use simple...

This paper describes optimal monetary policy in an economy with monopolistic competition, endogenous firm entry, a cash-in-advance constraint and pre-set wages. Firms must make profits in order to cover entry costs; thus a mark-up on goods prices is necessary. Without this mark-up, profits would...

This paper estimates a business cycle model with endogenous firm entry by matching impulse responses to a monetary policy shock in US data. Our VAR includes net business formation, profits and markups. We evaluate two channels through which entry may influence the monetary transmission process....

We characterize optimal monetary policy in a New Keynesian search-and-matching model where multiple-worker firms satisfy demand in the short run by adjusting hours per worker. Imperfect product market competition and search frictions reduce steady state hours per worker below the efficient...
