5. A Regime-Based View of the Economy

Unconventional: A Policymaker's Reflections on Crisis to Recovery

Unconventional A Policymaker's Reflections on Crisis to Recovery

"The St. Louis Fed has a long tradition of challenging the status quo. In 2016, Jim Bullard and the St. Louis Fed’s Research division pivoted to a new approach for evaluating the U.S. macroeconomy, which also had implications for how it views optimal monetary policy. Rather than assuming the economy will converge to one long-run outcome—the conventional approach—the St. Louis Fed now assumes the economy can switch between different states, or regimes, and the regime will influence the outlook for the macroeconomy and monetary policy."

—Christopher Waller, Executive Vice President and Director of Research

5. A Regime-Based View of the Economy

James Bullard shared some reflections on his first 10 years as Bank president during recent conversations with staff. The following are excerpts from those discussions.

Coming out of a recession, a typical forecast would suggest that the economy will grow faster for a while than it otherwise would, that job growth will be higher than normal for a while and that inflation might start to pick up and possibly go above the Fed's 2 percent target. Then, these variables would settle back to their steady-state rates of growth. That is, they would return to their average historical values. This approach to forecasting assumes that the economy will ultimately converge to a single, long-run outcome. It was the common approach used by many FOMC participants, including me.

Given that viewpoint, and since the Fed’s dual mandate (of stable prices and maximum sustainable employment) was close to being achieved in 2014, I had been an early proponent of moving forward with the normalization process, which included the policy rate's returning to its steady-state value.

But, by mid-2016, the Research team here at the Bank and I had become increasingly frustrated because our forecasts of the macroeconomy under this approach turned out to be wrong for four or five years in a row. Similarly, the "dot plots" in the FOMC's quarterly Summary of Economic Projections (SEP)—including the St. Louis Fed's dots, or projections for the policy rate—repeatedly projected many more increases in the policy rate over the forecast horizon than actually occurred. The conventional approach wasn’t useful.

Therefore, at the St. Louis Fed, we changed our approach to near-term forecasts of the macroeconomy and monetary policy in June 2016. The new approach required us to think differently about the possible long-run outcomes of the macroeconomy. Instead of having only one such long-run outcome, as was the thinking behind our previous narrative, the macroeconomy could switch between regimes (or steady states) and, therefore, could have a set of possible long-run outcomes.

The basic idea behind the new narrative was that there are three fundamental factors that can determine the nature of the regimes: productivity growth (which could be high or low), the real interest rate on short-term government debt (which could be high or low) and the state of the business cycle (expansion or recession).

The current regime appears to be characterized by low growth, low interest rates and also low inflation, which could be a relatively long-term outcome for the U.S. economy. The regime idea suggests that a situation like this could persist for many years and that we should not expect the same patterns from the previous decades to return, at least not in the near term.

This idea is particularly apt for the current environment. Safe, short-term real interest rates in the U.S. are extremely low and have been trending downward overall since the 1980s. Furthermore, the low safe real interest rates are a global phenomenon. For more recent trends in real-interest-rate regimes, see the presentation I delivered in Washington, D.C., on this topic.1


Labor Productivity Growth

Desire-for-Safe-Assets Regimes

As of February 2018, the U.S. appeared to be in a regime of low productivity growth and a high desire for safe assets. The latter is indicated by the relatively large negative value for ξ.

For purposes of monetary policy, which is regime-dependent, the planning horizon is two to three years.2 Given that long-run trends affecting the economy are unlikely to turn around in two to three years, we assume in our new narrative that the current regime will continue over that horizon.

The St. Louis Fed's projections for monetary policy are, therefore, calibrated for the low regime. Hence, our projected policy rate path is relatively flat over the forecast horizon, which stands in contrast with the FOMC's median path. If a regime switch were to occur, our forecasts would then be calibrated for that new regime. Upside risks to our forecasts (e.g., higher inflation, an increase in the real rate or higher productivity growth) would lead us to steepen our path for the policy rate.

DEEPER DIVE

The Maverick Monetarist Tradition

For many decades, the St. Louis Fed has maintained a reputation in the Federal Reserve System for challenging the status quo, enhancing the rigor of the monetary policy debate, and pushing the frontier of research in academic and policy circles.

The Bank came to be known as the "maverick" Federal Reserve bank during the Great Inflation period of the 1970s, when there was double-digit inflation and double-digit unemployment.1 "The famous misery index was off the charts," James Bullard said. The misery index, created in the 1970s by economist Arthur Okun, is equal to the sum of the inflation and unemployment rates.2

While this was a time of intense pressure on the Reserve banks to support System policy, the St. Louis Fed instead argued that Fed policies and excessive growth of the money supply were to blame for higher inflation.

For many decades, the St. Louis Fed has maintained a reputation in the Federal Reserve System for challenging the status quo ... [and] came to be known as the "maverick" Federal Reserve bank during the Great Inflation period of the 1970s.

"The St. Louis Fed stressed that the Fed really had to get this process under control," Bullard said, adding, "The monetarist experiment in the [Fed Chairman Paul] Volcker era was the ultimate outcome of that line of research, leading to much lower inflation, despite taking much of the 1980s to get it under control."

St. Louis Fed presidents were aided by analysis and data provided by research divisions led by Homer Jones, Leonall Andersen, Jerry Jordan and, later, Ted Balbach, who enhanced and expanded upon Jones’ initiatives.3

"We were the first Bank in the Federal Reserve System to do academic-style research and try to use that research to influence thinking on monetary policy," Bullard noted.

Under Jones, the St. Louis Fed became the first Reserve bank to go public with its own viewpoints and began publishing data and analysis for the public. When the Bank began to use mainframe computers around 1967, McDonnell Douglas provided computer access for the Research division. In this era, computer programs were created line by line on punch cards, which were transported by taxi from the Bank to McDonnell Douglas for processing.4 The division developed its international reputation for economic research and monetarist policy views that remains to this day, and it continues to be well-known for its publication of data and economic analysis, including its popular, publicly available database FRED®.

"The ideas about how to run monetary policy that came out of here and influenced U.S. policy also helped influence monetary policy around the world. This led to lower inflation around the world and eventually to the inflation targeting era starting in the 1990s," Bullard said.

He added, "There are many different challenges today in monetary policy than there have been historically, but the basic story remains that research is not just scribbling on a piece of paper. The ideas can be profoundly powerful and have huge influence on real people's lives."
