Should the central bank prevent 'excessive' asset price dynamics or should it wait until the boom spontaneously turns into a crash and intervene only afterwards? The debate over this issue goes back at least to the exchange between Bernanke-Gertler (BG) and Cecchetti but has not settled yet. In...

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...

We analyze the impact of price stability-oriented monetary strategies (inflation targeting — IT — and constraining exchange rate arrangements) on inflation persistence using a time-varying coefficients framework in a panel of 68 countries (1993–2013). We show that explicit IT has a...

We present an accessible narrative of the Turkish economy since its great 2001 crisis. We broadly survey economic developments and pay particular attention to monetary policy. The data suggests that the Central Bank of Turkey was a strong inflation targeter early in this period but began to pay...

Many inflation targeting central banks are facing calls to expand their list of policy goals. I discuss how recent research provides new insights into the goals of policy and the tradeoffs presented by multiple goals. I focus particular attention on the role of unemployment and labor market...

We develop a behavioral macroeconomic model in which agents use simple but biased rules to forecast future output and inflation. This model generates endogenous waves of optimism and pessimism (quot;Animal Spiritsquot;) that are generated by the correlation of biased beliefs. We contrast the...

This paper studies the challenge that increasing the inflation target poses to equilibrium determinacy in a medium-sized New Keynesian model without indexation fitted to the Great Moderation era. For moderate targets of the inflation rate, such as 2 or 4 percent, the probability of determinacy...

Given buoyant capital inflows and managed exchange rates the majority of emerging market central banks have continued to accumulate massive foreign reserves. If left unsterilized, the liquidity expansion can threaten domestic macroeconomic stability. To contain domestic inflation these central...

In a standard New Keynesian model, a myopic central bank concerned with stabilizing inflation and changes in the output gap will implement a policy under discretion that replicates the optimal, timeless perspective, precommitment policy. By stabilizing output gap changes, the central bank...
