Financial crises can have a severe impact on the real side of the economy with countries losing up to 20 percent of GDP. The paper studies rules that prevent financial instability and currency crises. These include institutional arrangements for a solid banking system, prudent regulations and...

The paper examines the effect of trend productivity growth on the determinacy and learnability of equilibria under alternative monetary policy rules. It shows that under a policy rule that responds to current period inflation and the output gap a higher trend growth rate relaxes the conditions...

This study analyzes the emergence of secular stagnation as the consequence of a rise in the preference for liquidity. Such a rise is caused by a persistent set of pessimistic expectations. This study also investigates the effectiveness of a broad range of demand-management policies in dealing...

This paper offers a reappraisal of the inflation-unemployment tradeoff, based on ?frictional growth,? describing the interplay between nominal frictions and money growth. When the money supply grows in the presence of price inertia (due to staggered wage contracts with time discounting), the...

The authors provides a rigorous analysis of Milton Friedman's parable of the 'helicopter' drop of money - a permanent/irreversible increase in the nominal stock of fiat base money which respects the intertemporal budget constraint of the consolidated Central Bank and Treasury - the State....

Governments through the ages have appropriated real resources through the monopoly of the 'coinage'. In modern fiat money economies, the monopoly of the issue of legal tender is generally assigned to an agency of the state, the Central Bank, which may have varying degrees of operational and...

We study the design of optimal monetary policy (Ramsey policies) in a model with sticky prices and unionized labour markets. Collective wage bargaining and unions monopoly power tend to dampen wage fluctuations and to amplify employment fluctuations relatively to a DNK model with walrasian...

This paper takes a new look at the long-run dynamics of inflation and unemployment in response to permanent changes in the growth rate of the money supply. We examine the Phillips curve from the perspective of what we call “frictional growth,” i.e. the interaction between money growth and...

The financial crisis 2008-2009 and the European sovereign debt crisis have shown that stress on financial markets is important for analyzing and forecasting economic activity. Since financial stress is not directly observable but is presumably reflected in many financial market variables, it is...
