He examined optimal policy both in ordinary times and in times when the zero lower bound (ZLB) on short-term nominal interest rates is encountered.

With the addition of heterogeneous labor supply to their model, the authors explore the question of whether monetary policy can and should revive declining labor force participation. Within this model, a large private credit market is essential to good macroeconomic performance, and the primary role of monetary policy is to keep the credit market functioning properly, or “complete.” The heterogeneous labor supply, whereby households supply different amounts of labor at different dates, is driven by demographic factors. Bullard noted that, within this model, policymakers would be able to carry out an optimal monetary policy independently of household labor supply decisions. “I see this result as helping to inform the debate on whether U.S. monetary policy needs to worry about declining U.S. labor force participation,” he said, adding, “the bottom line of this talk is that the answer is ‘no.’” Labor Force Participation Bullard noted that the U.S. labor force participation rate has been depressed since the large 2007-2009 recession, and portions of the current U.S. monetary policy discussion have been focused on reviving labor force participation. “Can monetary policy substantially affect labor force participation? If so, should it?” he asked. To help address these questions, he examined a traditional view regarding the decline in labor force participation, as well as an alternative view. The traditional view is based on the premise that different demographic groups tend to have different labor force participation rates. Hence, the decline in the overall participation rate re ects long-run changes in the composition of the U.S. population. James Bullard is president and chief executive o cer of the Federal Reserve Bank of St. Louis. In these roles, he participates in the Federal Open Market Committee (FOMC) and directs the activities of the Federal Reserve’s Eighth District. President's Website Speeches & Presentations Video Appearances Media Interviews Research Papers Monetary policy has no role to play under this view of the decline in labor force participation. Meanwhile, the alternative view argues that a large portion of the post-crisis decline in labor force participation is cyclical. Bullard cited a paper on this alternative view in which optimal monetary policy, after large recessions, takes a labor force participation gap into account.1 “Consideration of longer-term trends in labor force participation seems to be consistent with the traditional view,” Bullard said, noting that, as such, he and Singh based their model on the traditional view. “Household labor supply is heterogeneous, but independent of monetary policy choices, consistent with the traditional, demographically-based view of labor force participation,” he said. Credit Markets and Monetary Policy Turning to household credit markets, Bullard noted that they drew increased attention during the nancial crisis. “The desire behind many actual policy choices over the last several years has been to help credit markets perform better,” he said. In their model, the economy includes a large private credit market. Given the existence of income and wealth inequality in the model, “the role of credit markets, if they work correctly, will be to reallocate uneven income across the life cycle into perfectly equal consumption by cohort,” he explained. “Monetary policy will be conducted optimally to repair a friction in household credit markets,” he said. The friction is non-state contingent nominal contracting (NSCNC), which means that loan contracts are written in nominal terms and do not depend on whether the economy is experiencing high or low growth. Bullard explained that monetary policy can substitute for the missing state-contingent contracts by adjusting the price level when shocks hit the economy. “In ordinary times, optimal monetary policy looks like ‘nominal GDP targeting’— countercyclical price level movements,” he said. He then examined how complete credit markets could be maintained when a large and persistent negative shock hits the economy and the ZLB is encountered. “The central bank can promise a one-time increase in the price level for the following period su cient to keep the nominal rate positive. This must be part of a credible commitment to a policy rule,” he said. Bullard concluded that when the ZLB threatens, the central bank would want to keep nominal interest rates positive, not at zero. “This result is in stark contrast to common policy recommendations in recent years—forward guidance committing to stay at the ZLB even longer, or quantitative easing justi ed as ‘keeping longer-term nominal interest rates low,’” he said. 1 For the alternative view, see the 2014 paper by Christopher Erceg and Andrew Levin in the Journal of Money, Credit and Banking. For the traditional view, see the 2006 paper by Stephanie Aaronson et al. in the Brookings Papers on Economic Activity.
