Recent research has found that the dynamic properties of the New Keynesian model can be very different when the nominal interest rate is zero. Improvements in technology and reductions in the labor tax rate lower economic activity, and the size of the government purchase output multiplier can be...

This paper contributes to the policy evaluation literature by developing new strategies to study alternative policy rules. We compare optimal rules to simple rules within canonical monetary policy models. In our context, an optimal rule represents the solution to an intertemporal optimization...

The importance of liquidity and insolvency for nation states and banks has been highlighted by current economic woes in the eurozone and elsewhere. The concepts are grounded in monetary theory, which determine the way they are interpreted. Connected to the discussion of autometallism and...

This paper uses a range of structural VARs to show that the response of US stock prices to fiscal shocks changed in 1980. Over the period 1955-1980 an expansionary spending or revenue shock was associated with modestly higher stock prices. After 1980, along with a decline in the fiscal...

This paper identifies shocks to the Federal Reserve's inflation target as VAR innovations that make the largest contribution to future movements in long-horizon inflation expectations. The effectiveness of this scheme is documented via Monte-Carlo experiments. The estimated impulse responses...

The paper reviews the current literature on the subject in both the New Consensus and Post Keynesian frameworks. It shows that both approaches give to central banks a wrong goal (inflation, distribution, curbing speculation, and so on) and a wrong instrument (interest rate rule). The paper...

This paper uses a FAVAR model with external instruments to show that the policy uncertainty shocks are recessionary and are associated with an increase in the exit of firms and a decrease in entry and in the stock price with total factor productivity rising in the medium run. To explain this...

Does fiscal policy have large and qualitatively different effects on the economy when the nominal interest rate is zero? An emerging consensus in the New Keynesian literature is that the answer is yes. New evidence provided here suggests that the answer is often no. For a broad range of...

The European sovereign debt crisis represents an interesting opportunity to investigate the reaction of the European Central Bank as a crisis fighting institution and the importance of central bank personalities in policy execution. Accordingly, this paper aims at investigating to what extent...

The global financial crisis of 2007-09 has led to an intensive research program analyzing a wide range of issues related to financial crises. This paper presents a summary of a forthcoming book, Financial Crises: Causes, Consequences, and Policy Responses, that includes 19 contributions...
