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...

Demographic pressures will materialize in many economies over the next few decades. We examine the macroeconomic impact of alternative fiscal adjustment and structural reform strategies to address these global aging pressures using the IMF''s Global Fiscal Model (GFM). The results suggest...

We explore the underlying determinants of the macroeconomic effects of fiscal policy and tax and social security reform using the Global Fiscal Model (GFM). We show that the planning horizon of consumers, access to financial markets, and the elasticity of labor supply, as well as the...

This paper proposes a new measure of contagion that is good at anticipating future vulnerabilities. Building on previous work, it uses correlations of equity markets across countries to measure contagion, but in a departure from previous practice it measures contagion using the relationship of...

This paper focuses on how changes in financial plumbing of the markets may impact the monetary policy options as central banks contemplate lift off from zero lower bound (ZLB). Under the proposed regulations, banks will face leverage ratio constraints. As a result of quantitative easing (QE),...

Nonbanks such as central counterparties (CCPs) are a useful lens to see how regulators view the role of the lender-of-last-resort (LOLR). This paper explores the avenues available when a nonbank failure is likely, specifically by considering the options of keeping CCPs afloat. It is argued that...

Deleveraging has two components--shrinking of balance sheets due to increased haircuts/shedding of assets, and the reduction in the interconnectedness of the financial system. We focus on the second aspect and show that post-Lehman there has been a significant decline in the interconnectedness...

In the aftermath of the Lehman crisis, payouts (i.e., taxpayer bailouts) in various forms were provided by governments to a variety of financial institutions and markets that were outside the regulatory perimeter - the ?""shadow"" banking system. Although recent regulatory proposals attempt to...

Between 1980 and before the recent crisis, the ratio of financial market debt to liquid assets rose exponentially in the U.S. (and in other financial markets), reflecting in part the greater use of securitized assets to collateralize borrowing. The subsequent crisis has reduced the pool of...

Probability of default (PD) measures have been widely used in estimating potential losses of, and contagion among, large financial institutions. In a period of financial stress however, the existing methods to compute PDs and generate loss estimates that may vary significantly. This paper...
