Informational implications of interest rate rules
Returning to a topic first systematically treated by Poole (1970) in a textbook Keynesian model, this paper compares interest rate and money supply rules. Our analysis, by contrast, is conducted within a rational expectations macro model that incorporates flexible prices and informational frictions. With differential information, interest rate targets can affect the information content of market prices and real activity, but these real consequences can always be replicated by an appropriately chosen money stock rule with feedback to economic activity. However, when the policy authority has ...

On the implementation of Markov-perfect monetary policy
The literature on optimal monetary policy in New Keynesian models under both commitment and discretion usually solves for the optimal allocations that are consistent with a rational expectations market equilibrium, but it does not study whether the policy can be implemented given the available policy instruments. Recently, King and Wolman (2004) have provided an example for which a time-consistent policy cannot be implemented through the control of nominal money balances. In particular, they find that equilibria are not unique under a money stock regime and they attribute the non-uniqueness ...

Monetary policy and operating procedures in New Zealand
The Reserve Bank of New Zealand operates in a highly deregulated financial environment which lacks any interest rate regulation or reserve requirements. Yet the Reserve Bank has been able to implement effective monetary policy through a quantity-based procedure. This article analyzes the operating procedures of the Reserve Bank of New Zealand and the relatively small financial costs imposed by these procedures.

Interest rate rules and nominal determinacy
Monetary economists have recently begun a serious study of money supply rules that allow the Fed to adjustably peg the nominal interest rate under rational expectations. These rules vary from procedures that produce stationary nominal magnitudes to those that generate nonstationarities in nominal variables. Our paper investigates the determinacy properties of three representative interest rate rules. ; We use Blanchard and Kahn's solution technique as a starting point. It doesn't directly apply, so we first modify their procedure. We then narrow the range of solutions by considering the ARMA ...

Consumption and time use over the life cycle
The authors incorporate home production in a dynamic general equilibrium model of consumption and saving with illiquid housing and a collateralized borrowing constraint. They show that the model is capable of explaining life-cycle patterns of households' time use and consumption of different categories. Specifically, households' market hours and home hours are fairly stable early in the life cycle. Market hours start to decline sharply at age 50, while home hours begin to increase at age 55. Households' consumption of the market good, home input, and housing services all exhibit hump shapes ...

Inflation and real activity with firm-level productivity shocks
In the last ten years there has been an explosion of empirical work examining price setting behavior at the micro level. The work has in turn challenged existing macro models that attempt to explain monetary nonneutrality, because these models are generally at odds with much of the micro price data. In response, economists have developed a second generation of sticky-price models that are state dependent and that include both fixed costs of price adjustment and idiosyncratic shocks. Nonetheless, some ambiguity remains about the extent of monetary nonneutrality that can be attributed to costly ...

Some not so unpleasant monetarist arithmetic
This paper analyzes the quantitative significance of Sargent and Wallace's (1981) "Some Unpleasant Monetarist Arithmetic" in a model that is parameterized to correspond with U.S. data. The major result is that the monetarist arithmetic is not overly unpleasant and that the nominal side of the economy is not very sensitive to whether money growth does or does not respond to government debt.

An examination of international trade data in the 1980s
This article examines three competing hypotheses and their ability to explain events in international financial markets during the 1980s. The rival hypotheses view the trade deficit as caused alternatively by large U.S. budget deficits, by tight U.S. monetary policy, or by real shocks to investment resulting from changes in the U.S. tax code. While no entirely consistent explanation emerges, the real-shock hypothesis seems to match the data best.
