On this episode, Martin Neil Baily of Brookings speaks with Guido Lorenzoni, economist and co-author of a paper on wage-price spirals. They discuss how rising wages and prices can affect each other and drive inflation. The study suggests that wages can increase faster than inflation, at least for a time, without spinning the economy out of control. The podcast explores the interplay between wages and prices, scenarios of inflation and wage growth, optimal policy in managing overheated economy, and the response to supply shocks and sectoral shifts.
Shortages of other inputs, such as energy or materials, can drive wage price spirals.
The unique timing and the role of supply shocks, such as the increase in commodity prices, have contributed to the current pattern of rising wages and prices.
Deep dives
Definition of Wage Price Spirals
A wage price spiral refers to a generalized inflation process where both prices and wages are rising, creating a self-perpetuating feedback loop. However, economists have struggled to incorporate this concept into their models. Yvonne Werning and Guido Lorenzoni's research reveals that wage price spirals are actually hidden within existing economic models. They show that shortages of other inputs, such as energy or materials, can drive wage price spirals. Despite recent inflationary concerns, the researchers offer an optimistic conclusion that real wages can return to trend without being persistently undermined by inflation.
The Challenge of Wage Price Spirals and the 70s
The 1970s served as a prototypical period for wage price spirals, with wages and prices rising in lockstep. In contrast, recent events have shown different patterns where prices and wages have reacted differently and with different timing. This highlights the essence of a wage price spiral, which involves disappointment on both sides - workers striving to keep up with rising prices and firms attempting to maintain their profit margins. Despite rising wages and prices, the U.S. does not currently face a wage price spiral. The paper suggests that the unique timing and the role of supply shocks, such as the increase in commodity prices, have contributed to this pattern.
Optimal Policies and Implications for the Future
The paper explores the question of optimal policy and points out that sometimes it may be optimal for the central bank to tolerate excess inflation during periods of strong economic performance. This challenges the conventional belief that the central bank should always aim for a zero output gap. The real wage and the scarcity of non-labor inputs play a significant role in understanding wage and price dynamics. Going forward, the paper suggests that further monetary tightening may not be necessary if the optimistic scenario of inflation returning to normal is accurate. Additionally, it emphasizes the importance of monitoring not only the labor market but also tightness in the input and goods market to fully grasp the inflationary pressures.
Economists have long debated the potential for rising wages and prices to push each other increasingly higher, driving inflation out of control—the so-called “wage-price spiral.” Concern about such a spiral has been high in the post-pandemic era, with inflation still running notably higher than the Federal Reserve’s 2% target. On this episode of the Brookings Podcast on Economic Activity, Martin Neil Baily of Brookings talks with the authors of a new BPEA paper on wage-price spirals, Guido Lorenzoni and Iván Werning. Their study, which developed a new model for this economic scenario, contends that because various factors drove price growth to outpace wages just after the pandemic, wages can increase faster than inflation, at least for a time, without necessarily spinning the economy out of control.
