Central Bank forecasts and disclosure policy: Why it pays to be optimistic

In a model with forward-looking behavior, we study disclosure policy when a central bank has private information on the future state of the economy. We find that the effects of advance disclosure depend on the presence of uncertainty about policy targets when the shock occurs. With uncertainty about policy targets, disclosure is harmless to current outcomes, owing to the strong dependence of inflation expectations on policy actions, which induces the central bank to focus exclusively on price stability. If the central banks targets are common knowledge, disclosure of future shocks impairs stabilization of current inflation and output.

JOB TURNOVER, TREND GROWTH, AND THE LONG-RUN PHILLIPS CURVE

The paper reexamines the long-run Phillips curve in a New Keynesian model with job turnover and trend productivity growth. We show that an increase in money growth has substantial positive effects on steady state output, consumption, and employment in the presence of (i) observed job turnover rates and, if consumption smoothing is sufficiently strong, (ii) observed productive growth rates. Furthermore, we show that the optimal inflation rate is slightly under 2% for reasonable calibrations of job turnover and trend growth.

A NOTE ON TREND GROWTH AND LEARNING ABOUT MONETARY POLICY RULES IN A TWO-BLOCK WORLD ECONOMY

We analyze the implications of openness and growth for determinacy and learnability of rational expectations equilibria in a two-country New Keynesian model with alternative monetary policy rules. Under the contemporaneous data rule, the conditions for determinacy and learnability become more stringent as a result of openness but less stringent as a result of growth, so that growth weakens the effect of openness. Under the expectations-based rule, the conditions for determinacy and learnability also become more stringent as a result of openness, whereas as a result of trend growth the conditions for determinacy also become more stringent (thus reinforcing the effect of openness) but those for learnability become less stringent (thus weakening the effect of openness). As in related studies, the elasticity of intertemporal substitution is key to our result, but within a framework that is consistent with long-run labor supply and balanced growth facts.
