Abstract:
Over the past 30 years (1990-2019), African economies have experienced remarkable improvements in macroeconomic conditions, characterized by higher and more stable real per-capita growth rates, and lower and more stable inflation. This paper documents the persistent decline in macroeconomic volatility at the aggregate and sectoral levels, and seeks to provide explanations. Sectoral analysis shows a particularly strong reduction of growth volatility in agriculture, and, to a lesser extent, in services. Analysis of a broad range of explanatory factors yields that only a small fraction of the moderation can be explained by structural change, and changes in major structural characteristics such as institutions, trade intensity and diversification, natural resource dependence, or conflict incidence. Evidence suggests that changes in the external environment, improved macroeconomic policy frameworks, and ’softer’ structural improvements such as the deepening of the financial sector and increases in human capital, were important towards reducing volatility on the continent.

72. On the Non-Inflationary effects of Long-Term Unemployment Reductions

Abstract:
The paper critically examines the New Keynesian explanation of hysteresis based on the role of long-term unemployment. We first examine its analytical foundations, according to which rehiring long-term unemployed individuals would not be possible without accelerating inflation. Then we empirically assess its validity along two lines of inquiry. First, we investigate the reversibility of long-term unemployment. Then we focus on episodes of sustained long-term unemployment reductions to check for inflationary effects. Specifically, in a panel of 25 OECD countries (from 1983 to 2016), we verify by means of local projections whether they are associated with inflationary pressures in a subsequent five-year window. Two main results emerge: i) the evolution of the long-term unemployment rate is almost completely synchronous with the dynamics of the total unemployment rate, both during downswings and upswings; ii) we do not find indications of accelerating or persistently higher inflation during and after episodes of strong declines in the longterm unemployment rate, even when they occur in country-years in which the actual unemployment rate was estimated to be below a conventionally estimated Non-Accelerating Inflation Rate of Unemployment (NAIRU). Our results call into question the role of long-term unemployment in causing hysteresis and provide support to policy implications that are at variance with the conventional wisdom that regards the NAIRU as an inflationary barrier.

73. Inflation? It’s Import Prices and the Labor Share!

Abstract:
Recognizing that inflation of the value of output and its costs of production must be equal, we focus on a cost-based macroeconomic structuralist approach in contrast to micro-oriented monetarist analysis. For decades the import and profit shares of cost have risen, while the wage share has declined to around 50% with money wage increases lagging the sum of growth rates of prices and productivity. Conflicting claims to income are the underlying source of inflationary pressure. Inflation affects income (labor’s spending power) and wealth. Monetarist theory around 1900 concentrated on the latter (Bryan and the “Cross of Gold)” leading to the standard Laffer curve. It was replaced by the Friedman-Phelps model which has incorrect dynamics (labor payments do not fall during an expansion – they go up). Samuelson and Solow introduced a version of the Phillips curve that violates macroeconomic accounting. Rational expectations replaced Friedman but was immediately falsified by output drops after the Volcker shock treatment around 1980. There followed a complicated transition from rational expectations to inflation targeting, anchored by economists’ misunderstanding of the physical meaning of ergodicity and ontological blindness. It did not help that the real balance effect is irrelevant because money makes up a small part of wealth. Rather than issuing veiled threats of disaster if its policy advice is not followed, the Fed now announces inflation targets which it cannot meet. Contemporary structuralist theory suggests that conflicting income claims set the inflation rate. Firms can mark up costs but workers have latent bargaining power over the labor share that they can exercise. Import costs and policy repercussions complicate the picture, but a simple vector error correction model and visual analysis suggest that money wages would have to grow one percentage point faster than prices plus productivity for several years if the Fed is to meet a three percent inflation target. The results pose a Biden policy trilemma: (i) the only path toward a more egalitarian size distribution of income is through a rising labor share (money wage growth exceeds price plus productivity growth), (ii) which would provoke faster inflation with feedback to rising interest rates, and (iii) the resulting asset price deflation likely facing political resistance from Wall Street and affluent households.

74. Another reason to raise the Fed's inflation target: An employment and output boom

Author:
David Reifschneider and David Wilcox

Content Type:
Policy Brief
Institution:
Peterson Institute for International Economics (PIIE)
Abstract:
In 2012, the Federal Reserve formally adopted an inflation target and set it at 2 percent, in line with the level chosen by many other central banks. In hindsight, this setting left policymakers with too little room to cut interest rates when they want to fight recessions. Many researchers have noted that if central banks raised their inflation targets—either individually or in concert—they could do a better job in the long run of keeping inflation near its target and the workforce fully employed. Reifschneider and Wilcox highlight an additional and less-noted consequence of raising the inflation target modestly: The economy could enjoy a temporary but substantial boom in employment and output as it adjusted to the increase in the target. Critical to generating this favorable outcome would be decisive action by monetary policymakers to ensure that the higher inflation target is achieved in a reasonably timely manner. In light of substantial transition benefits, as well as the long-run improvement in economic performance, the authors recommend that the Federal Reserve raise its inflation target to 3 percent as part of its next framework review.

75. An Uneven Global Rebound Will Challenge Emerging-Market and Developing Economies

Author:

Content Type:
Policy Brief

Peterson Institute for International Economics (PIIE)
Abstract:
As the US economy rebounds amid elevated inflationary pressures and Europe grows at a rapid clip, an uneven global rebound looms. Although emerging-market and developing economies (EMDEs) generally retain good access to global capital markets for now, their relatively slow pace of COVID-19 vaccination will continue to hamper their economic recoveries and strain their public finances—already stretched owing to the fiscal pressures of the pandemic over the past year and a half. Higher interest rates in the rich countries, particularly the United States, could tip EMDEs into liquidity and even solvency crises. The likelihood of crises is higher if advanced-economy central banks move abruptly, surprising markets. Global policymakers should prepare now by enhancing mechanisms for providing liquidity to EMDEs and, in cases of insolvency, for restructuring their sovereign debts. Perhaps even more important, the scope for uneven recovery can be limited if rich countries make an all-out effort to deliver vaccines globally and enhance less prosperous countries’ infrastructures for getting shots into arms.

76. Low inflation bends the Phillips curve around the world: Extended results

Author:

Working Paper
Institution:
Peterson Institute for International Economics (PIIE)
Abstract:
This paper revises and extends PIIE Working Paper 20-6. It continues to find strong support for a Phillips curve that becomes nonlinear when inflation is "low"—which our baseline model defines as less than 3 percent. The nonlinear curve is steep when output is above potential (slack is negative) but flat when output is below potential (slack is positive) so that further increases in economic slack have little effect on inflation. This finding is consistent with evidence of downward nominal wage and price rigidity. When inflation is high, the Phillips curve is linear and relatively steep. These results are robust to placing the threshold between the high and low inflation regimes at 2, 3, or 4 percent inflation or for a threshold based on country-specific medians of inflation. In this nonlinear model, international factors play a large role in explaining headline inflation (albeit less so for core inflation), a role that has been increasing since the global financial crisis.

77. Does money growth tell us anything about inflation?

Author:
Francesco Papadia and Leonardo Cadamuro
Publication Date:

Content Type:
Working Paper
Institution:
Bruegel
Abstract:
Economists and central bankers no longer consider monetary aggregates relevant for inflation forecasts. We explain this neglect by advancing and testing the hypothesis that monetary aggregates are only relevant for inflation in unsettled monetary and inflationary conditions. When inflation is basically stable around the central bank target (1.9 percent), as it has been in most of the last two decades, there is no apparent relationship between monetary aggregates and inflation. This is not surprising: there is not much to be explained about a constant.

78. Timely measurement of real effective exchange rates

Author:
Zsolt Darvas
Publication Date:

Content Type:
Working Paper
Institution:
Bruegel
Abstract:
We demonstrate that short-run real exchange effective rate changes are dominated by nominal effective exchange rate changes, while inflation rates are sticky and contribute little to short-run real exchange rate changes. These observations allow a rather accurate real-time approximation of the real effective exchange rate using actual nominal exchange rate data and forecast inflation data. We measure the approximation error and find it is minor for most countries and sizeable only for a few countries experiencing high and volatile inflation. For a set of countries, the revision in our estimates using real-time data is slightly lower than the revision in World Bank estimates and much lower than International Monetary Fund estimates. By considering two widely studied economic issues, unit root testing in real exchange rates and nominal exchange rate forecasting with the real exchange rate, we find that using a version of real exchange rates based on approximated monthly price level data instead of actual price level data hardly changes the conclusions on unit roots and forecasting. By combining alternative data sources for exchange rates and consumer prices, we calculate up-to-date monthly real effective exchange rates for 177 countries and the euro area. Our dataset, which is frequently updated, includes more than twice as many observations as the second most comprehensive dataset.

79. The Evolution of the Earnings Distribution in a Volatile Economy: Evidence from Argentina

Abstract:
This paper studies earnings inequality and dynamics in Argentina between 1996 and 2015. Following the 2001–2002 crisis, the Argentine economy transitioned from a low- to a highinflation regime. At the same time, the number of collective bargaining agreements increased, and minimum wage adjustments became more frequent. We document that this macroeconomic transition was associated with a persistent decrease in the dispersion of real earnings and cyclical movements in higher-order moments of the distribution of earnings innovations. To understand this transition at the micro level, we estimate processes of regular wage adjustments within job spells. As the Argentine economy transitioned from low to high inflation, the monthly frequency of regular wage adjustments almost doubled, while the distribution of changes in regular wages morphed from having a mode close to zero and being positively skewed to having a positive mode and being more symmetric.

80. How Govenrment Outflow and Public Debt Affect Inflation: Evidence from See Countries

Author:

Journal of Liberty and International Affairs
Abstract:
The study aims to address public debt and government outflow affecting inflation in some of the countries of Southeast Europe, observing a combination of factors both theoretically and econometrically. The investigation included six (6) SEE countries, including the 2006-2020 timeframe, with 90 observations. The dynamic approach, the fixed effect, and the Arellano/Bond estimator were used to check the parameters considered in the study using panel data. Furthermore, the study also applied diagnostic tests such as the Sargan over-identifying restrictions and Pedroni test for cointegration. The results of the fixed effect and Arellano / Bond estimation demonstrate that public debt, current budget outflows, and capital budget outflows affect inflation, while overall budget outflows are insignificant. For further studies, it would be useful to apply other dynamic models by applying other specific factors, which will be considered as a useful contribution to the academic, research, and policy-making structures.
