In the study, the relevance of several optimum-currency-area (OCA) criteria is formally worked out in a welfare approach. The optimum monetary-policy rules of the supranational central bank are derived within the Barro-Gordon framework, and consideration is given to how the welfare of the member...

Could a researcher or policy analyst use data reported from surveys of consumer confidence to improve forecasts of consumer spending? This issue has been examined in the literature previously, which reached the conclusion that consumer confidence helped improve the forecasts slightly. But that...

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...

The role of bank capital as a propagation channel of shocks is strongly pronounced in recent macroeconomic models. In this paper, we show how the evolution of bank capital depends on the share of non-state-contingent assets in banks' balance sheets and present the consequences for macroeconomic...

In this paper we set up a New-Keynesian model with a heterogenous banking sector to analyze liquidity problems on the interbank market. The presence of an interbank market is essential to consider a situation where an increased liquidity supply by the central bank is only partially passed on to...

This paper compares the consequences of equity injections into banks with purchases of corporate and government bonds in a financial crisis situation using a New Keynesian model in which non-financial firms predominantly take non-market-based debt from banks instead of issuing securities. Our...

We estimate the low-frequency relationship between fiscal deficits and inflation and pay special attention to its potential time variation by estimating a time-varying VAR model for U.S. data from 1900 to 2011. We find the strongest relationship neither in times of crisis nor in times of high...

The extensive public support measures for the financial sector have been key for the management of the current financial crisis. This paper gives a detailed description of the measures taken by central banks and governments and attempts a preliminary assessment of the effectiveness of such...

By combining the approaches of Gertler and Karadi (2011) and Bernanke et al. (1999), I develop a DSGE model with leverage constraints both in the banking and in the non-financial firm sector. I calibrate this full model to US data. In a world with only a monetary policy and a productivity shock,...

The impact of unconventional monetary policies on exchange rates and its spillovers to other economies is not yet fully understood. In this paper I develop a two-country DSGE model with interbank markets and endogenous default probabilities to analyze the cross-border impacts of unconventional...
