This paper introduces agent heterogeneity, liquidity, and endogenous default to a DSGE framework. Our model allows for a comprehensive assessment of regulatory and monetary policy, as well as welfare analysis in the different sectors of the economy. Due to liquidity and endogenous default, the...

Insufficient capital buffers of banks have been identified as one main cause for the large systemic effects of the recent financial crisis. Although higher capital is no panacea, it yet features prominently in proposals for regulatory reform. But how do increased capital requirements affect...

Most theoretical central bank models use short horizons and focus on a single tradeoff. However, in reality central banks play complex, long horizon games and face more than one tradeoff. We account for these issues in a simple infinite horizon game with a novel tradeoff: higher rates deter...

Channel systems for conducting monetary policy are becoming increasingly popular. Despite their popularity, the consequences of implementing policy with a channel system are not well understood. We develop a general equilibrium framework of a channel system and investigate the optimal policy. A...

This paper investigates the impact of international shocks – interest rate, commodity price and industrial production shocks – on key macroeconomic variables in ten Central and Eastern European (CEE) countries by using near-VAR models and monthly data from the early 1990s to 2009. In...

When agents are liquidity constrained, two options exist — sell assets or borrow. We compare the allocations arising in two economies: in one, agents can sell government (outside) bonds and in the other they can borrow by issuing (inside) bonds. All transactions are voluntary, implying no...

The Friedman rule states that steady-state welfare is maximized when there is deflation at the real rate of interest. Recent work by Khan et al (2003) uses a richer model but still finds deflation optimal. In an otherwise standard new Keynesian model we show that, if households have hyperbolic...

As shown in Sinn and Wollmershäuser (2012a), during the European balance-of-payments crisis, inter-governmental credit and Target credit granted by core-country central banks have replaced private international capital flows in financing the crisis countries' current account deficits, and even...

We present a new partial equilibrium theory of price adjustment, based on consumer loss aversion. In line with prospect theory, the consumers’ perceived utility losses from price increases are weighted more heavily than the perceived utility gains from price decreases of equal magnitude. Price...

Using the new unit root test by Phillips et al. (2011) we show that the Target balances of the German Bundesbank have been exploding from the beginning of 2009 to the beginning of 2013. By implementing a full-allotment policy and reducing the required minimum quality of collaterals in October...
