We use the IMF's Global Fiscal Model to evaluate recent proposals to reform social security and the tax system in the United States. Introducing personal retirement accounts is unlikely to yield significant macroeconomic benefits unless it spurs additional fiscal consolidation to prevent a large...

The Flexible System of Global Models (FSGM) is a group of models developed by the Economic Modeling Division of the IMF for policy analysis. A typical module of FSGM is a multi-region, forward-looking semi-structural global model consisting of 24 regions. Using the three core modules focused on...

Robust GDP growth, declining unemployment, low and stable inflation, and a string of fiscal and current account surpluses -- it's a record to be envied. These outcomes in Canada owe much to sound macroeconomic policies, as well as to a favorable external environment. This book focuses on these...

Over the past two years, the IMF staff has been developing a new multicountry macroeconomic model called the Global Economy Model (GEM). This paper explains why such a model is needed, how GEM differs from its predecessor model, and how the new features of the model can improve the IMF’s...

A crisis is a terrible thing to waste, and nowhere is this truer than in the arena of international economic policy cooperation. With the world facing the largest and most synchronized plunge in output of the postwar era, policy makers banded together to find solutions. This paper looks at the...

The proposed SDN would take stock of the current debate on the shape that monetary policy should take after the crisis. It revisits the pros and cons of expanding the objectives of monetary policy, the merits of turning unconventional policies into conventional ones, how to make monetary policy...

We estimate tax multipliers in a "Blanchard-Yaari" consumption model where Ricardian equivalence is broken because the private sector discounts the future at a faster rate than the real rate of interest. The model fits U.S. data since 1955 extremely well-entailing a discount wedge of around 20...

This paper proposes a markedly different transmission mechanism from monetary policy to the macroeconomy, focusing on how policy changes nominal inertia in the Phillips curve. Using recent theoretical developments, we examine the properties of a small, estimated U.S. monetary model...

This paper looks at whether the aggregate ERM money supply has been a useful predictor of short-term changes in inflation and growth, and long-term trends in price levels among the core ERM countries. The evidence suggests that over the period since 1987, when there have been no realignments,...
