Abstract:
This paper models inflation by combining the multicountry framework of one of its authors (Forbes) with the nonlinear specification proposed by the other two (Gagnon and Collins). The results find strong support for a Phillips curve that becomes nonlinear when inflation is low, in which case excess economic slack has little effect on inflation. This finding is consistent with evidence of downward nominal wage and price rigidity. The estimates also show a significant and economically meaningful Phillips curve relationship between slack and inflation when slack is negative (i.e., when output is above long-run potential). In this nonlinear model, international factors play a large role in explaining headline inflation, a role that has increased over time, supporting the results of Forbes’ linear model.

Abstract:
The world's leading economic powers must cooperate more to combat the health and economic shocks resulting from the COVID-19 pandemic. In a new PIIE Briefing, Peterson Institute experts outline how collective action by the Group of Twenty (G20) nations can make a difference. The PIIE agenda includes removal of trade barriers impeding the flow of medical supplies and food, and more money for research, testing, and disease control, especially for debt-burdened low-income countries. The World Bank and the World Health Organization need more resources to relieve suffering, and the International Monetary Fund must step up to stabilize the world financial system.

3. Are Central Banks Out of Ammunition to Fight a Recession? Not Quite.

Abstract:
Central banks in the three largest advanced economies (the United States, Japan, and the eurozone) have only limited ammunition to fight a recession based on the tools used to date. The Federal Reserve has the most amount of tried and tested ammunition in this group. If a recession were to hit the US economy now, the Fed would be able to deliver monetary stimulus equivalent to a cut in the short-term policy interest rate of about 5 percentage points, which is sufficient to fight a mild but not severe recession. The European Central Bank and the Bank of Japan have little ability to ease policy with tools used to date, about the equivalent of a 1 percentage point cut in the policy rate. But they can engage in more exotic forms of monetary policy, such as large-scale purchases of equity and real estate and direct transfers to households, which the Fed cannot do. These tools, however, are largely untested and face political resistance. An important implication of this analysis is that raising expected inflation before a recession hits has a much larger benefit than has been widely recognized. A higher long-run inflation rate gives central banks more room to not only cut their policy rates but also use forward guidance and quantitative easing to reduce longer-term rates.

4. Low Inflation Bends the Phillips Curve

Abstract:
The Phillips curve, which traces out a negative relationship between inflation and unemployment, has undergone tremendous changes over more than 100 years. Some researchers argue that the slope of the curve in the United States fell substantially around 20 years ago so that unemployment now has little or no effect on inflation. This paper shows that another hypothesis is equally consistent with the data: The Phillips curve may be nonlinear when inflation is low, with the economy having operated in the flat region of the curve for most of the past 20 years. The next few years may be decisive in the debate between these hypotheses, as unemployment has returned to a range in which a nonlinear curve ought to display significant steepness. A flat Phillips curve implies little change in inflation going forward, but a nonlinear curve implies moderate increases in inflation over the next few years.

5. Why Has the Stock Market Risen So Much Since the US Presidential Election?

Abstract:
Immediately following the US presidential election in November 2016, many economists were concerned that increased uncertainty over economic policy would lead to a decline in the US stock market. From the time of the election to the end of 2017, however, the stock market, as measured by the Standard and Poor's (S&P) 500 index, increased by about 25 percent. Price swings since then have led investors and economists to increasingly ask: Was the stock market rise justified by an increase in actual and expected future dividends, or did it reflect unhealthy price developments, which may reverse in the future?
