In many applications of habit persistence to macroeconomics, it is of little significance whether habits are internal or external. In this paper, it is shown that the distinction between internal and external habits is important in a situation wherein a shock is news about the future. An...

A news-driven business cycle is a positive comovement of consumption, output, labor, and investment from the news about the future. We show that nominal rigidities, especially sticky prices, can cause it in an estimated medium-scale DSGE economy.

A recent study shows that equilibrium indeterminacy arises if monetary policy responds to asset prices, especially share prices, in a sticky-price economy. We show that equilibrium indeterminacy never arises if the working capital of firms is subject to their asset values by financial frictions.

Carlstrom and Fuerst (2007) [``Asset prices, nominal rigidities, and monetary policy,'' Review of Economic Dynamics 10, 256--275] find that monetary policy response to share prices is a source of equilibrium indeterminacy because an increase in inflation implies a high real marginal cost and low...

Many researches that apply business cycle accounting (hereafter, BCA) to actual data conclude that models with investment frictions or investment wedges are not promising for modeling business cycle dynamics. In this paper, we apply BCA to artificial data generated by a variant model of...

This paper investigates the monetary policy design for restoring equilibrium determinacy. Our interests are whether a central bank should respond to asset price fluctuations, and if so, what asset prices should be targeted. We show that a monetary policy response to the price of a productive...
