Intuitively core inflation is understood as a measure of inflation where noisy price movements are avoided. This is typically achieved by either excluding or downplaying the importance of the most volatile items. However, some of those items show high persistence, and one certainly does not want...

The financial crisis in the advanced countries that began in 2007 has led central bankers to adopt unconventional policy measures as policy interest rates neared the zero bound. One suggestion (Blanchard, Dell’Ariccia, and Mauro, 2010) has been to raise inflation targets to provide more...

Output gap estimates are subject to a wide range of uncertainty owing to data revisions and the difficulty in distinguishing between cycle and trend in real time. This is important given the central role in monetary policy of assessments of economic activity relative to capacity. We show that...

This is the sixth of a series of papers that are being written as part of a project to estimate a small quarterly Global Projection Model (GPM). The GPM project is designed to improve the toolkit to which economists have access for studying both own-country and cross-country linkages. In this...

We develop a semi-structural new-Keynesian open-economy model, with separate food and non-food inflation dynamics, for forecasting and monetary policy analysis in low-income countries and apply it to Kenya. We use the model to run several policy-relevant exercises. First, we filter international...

This paper applies a state-space approach to estimate the implicit inflation target of the South African Reserve Bank (SARB) since the adoption of the Inflation Targeting (IT) framework. The paper's findings are two. First, although the official inflation target range is 3.6 percent, in...

We extend the Global Projection Model (GPM) to include a separate block for China. China plays an important role in shaping global economic outcomes, given its sheer size and trade integration with other key economies, its demand for commodities, and its policies. Also, the Chinese economy has...

We study the effects and historical contribution of monetary policy shocks to consumption and income inequality in the United States since 1980. Contractionary monetary policy actions systematically increase inequality in labor earnings, total income, consumption and total expenditures....

This paper discusses interlinkages between Poland and the euro zone using a simple and agnostic econometric approach. Specifically, we estimate a trend-cycle VAR model using data for real and nominal variables, imposing powerful but uncontroversial assumptions that allow us to identify how...

Many central banks target an inflation rate near two percent. This essay argues that policymakers would do better to target four percent inflation. A four percent target would ease the constraints on monetary policy arising from the zero bound on interest rates, with the result that economic...
