Interest rate versus money supply instruments: on the implementation of Markov-perfect optimal monetary policy
Currently there is a growing literature exploring the features of optimal monetary policy in New Keynesian models under both commitment and discretion. With respect to time consistent policy, the literature focuses on solving for allocations. Recently, however, King and Wolman (2004) have examined implementation issues involved under time consistent policy when the monetary authority chooses nominal money balances. Surprisingly, they find that equilibria are no longer unique under a money stock regime. Indeed, there exist multiple steady states. Dotsey and Hornstein find that King and ...

Labor-Market Wedge under Engel Curve Utility: Cyclical Substitution between Necessities and Luxuries
In booms, households substitute luxuries for necessities, e.g., food away from home for food at home. This cyclical pattern of composition changes in the consumption basket has the potential to reduce the volatility of measures of the labor-market wedge, the gap between the marginal rate of substitution and the real wage. Based on household expenditure patterns from the Consumer Expenditure Survey, we show that this composition bias has only a limited impact on the measured labor-market wedge, accounting for 6 percent to 16 percent of its cyclical volatility.

Potential causes and implications of the rise in long-term unemployment
Long-term unemployment rose dramatically during the recent recession and remains elevated. A primary cause may be the fact that more workers with inherently low job finding rates have become unemployed. This would suggest that the natural rate of unemployment has increased, and that additional monetary stimulus may have only a limited effect on reducing unemployment.

On the implementation of Markov-perfect interest rate and money supply rules: global and local uniqueness
Currently there is a growing literature exploring the features of optimal monetary policy in New Keynesian models under both commitment and discretion. This literature usually solves for the optimal allocations that are consistent with a rational expectations market equilibrium, but it does not study how the policy can be implemented given the available policy instruments. Recently, however, King and Wolman (2004) have shown that 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 ...

Aggregate Effects of the Adoption of AI
AI is holding out the prospect of substantial productivity improvements. While the potential of AI may be large, it is uncertain how much of that potential will be realized and how fast it will occur. Recent estimates of the medium-term AI impact on labor productivity range from negligible to larger than the 1990s IT impact. But should AI meaningfully affect medium-term productivity growth, monetary policy is likely to respond by accommodating the increase in potential output. On the other hand, recalling the 1990s IT diffusion, one should not be too surprised that, even though AI is ...

How Much Has Job Matching Efficiency Declined?
During the recession and recovery, hiring has been slower than might be expected considering the large numbers of vacant jobs and unemployed individuals. This raises some concern about structural changes in the process of matching job seekers with employers. However, the standard measures account for only the unemployed and not those who are out of the labor force. Including other non-employed groups in the measured pool of job seekers while adjusting for different job finding rates among these groups shows that the decline in matching efficiency is similar to earlier declines.

Generalized Matching Functions and Resource Utilization Indices for the Labor Market
In the U.S. labor market unemployed individuals that are actively looking for work are more than three times as likely to become employed as those individuals that are not actively looking for work and are considered to be out of the labor force (OLF). Yet, on average, every month twice as many people make the transition from OLF to employment than do from unemployment. Based on these observations we have argued in Hornstein, Kudlyak, and Lange (2014) for an alternative measure of resource utilization in the labor market, a non-employment index, which is more comprehensive than the standard ...
