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...

I summarize recent progress made in the literature on inflation dynamics. This has been a very productive area of research due to the development of the so-called New Keynesian model and the availability of new macroeconomic and microeconomic evidence. Nevertheless, a number of problems still...

We estimate the effects of exogenous innovations to the balance sheet of the ECB since the start of the financial crisis within a structural VAR framework. An expansionary balance sheet shock stimulates bank lending, stabilizes financial markets, and has a positive impact on economic activity...

Robert Triffin became famous with his trenchant analyses of the vulnerabilities of the Bretton Woods system. These are still at the center of many discussions today. This paper argues that there is a remarkable continuity in Triffin's work. From his earliest writings, Triffin developed a vision...

This paper presents new evidence on the patterns of price and wage adjustment in European firms and on the extent of nominal rigidities. It uses a unique dataset collected through a firm-level survey conducted in a broad range of countries and covering various sectors. Several conclusions are...

This study investigates the pricing behaviour of firms in the euro area on the basis of surveys conducted by nine Eurosystem national central banks. Overall, more than 11,000 firms participated in the survey. The results are very robust across countries. Firms operate in monopolistically...

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...

We estimate the effects of exogenous innovations to the balance sheet of the ECB since the start of the financial crisis within a structural VAR framework. An expansionary balance sheet shock stimulates bank lending, stabilizes financial markets, and has a positive impact on economic activity...

Survey results in 15 European countries for almost 15,000 firms reveal that Belgian firms react more than the average European firm to adverse shocks by reducing permanent and temporary employment. On the basis of a firm-level analysis, this paper confirms that the different reaction to shocks...

We analyze the impact of the countercyclical capital buffers held by banks on the supply of credit to firms and their subsequent performance. Countercyclical ‘dynamic’ provisioning unrelated to specific loan losses was introduced in Spain in 2000, and modified in 2005 and 2008. The resultant...
