We argue that the U.S. personal saving rate's long stability (from the 1960s through the early 1980s), subsequent steady decline (1980s - 2007), and recent substantial increase (2008 - 2011) can all be interpreted using a parsimonious 'buffer stock' model of optimal consumption in the presence...

We argue that the U.S. personal saving rate’s long stability (from the 1960s through the early 1980s), subsequent steady decline (1980s - 2007), and recent substantial increase (2008 - 2011) can all be interpreted using a parsimonious ‘buffer stock’ model of optimal consumption in the...

Evans (1991) has demonstrated that Blanchard’s (1985) finite-horizon model obeys approximate Ricardian equivalence. We show that this result is determined largely by an unrealistic assumption that labor income grows monotonically over a consumer’s entire lifetime. Introducing more realistic...

This paper examines the macroeconomic implications of life-cycle and dynastic saving behavior for closed and small, open economies. Using an extended version of Blanchard’s overlapping agents model, the analytical framework nests these two competing views, treating agents as either dynastic...

High levels of economic policy uncertainty in various parts of the world revamped the de- bate about its impact on economic activity. With increasingly stronger economic, financial, and political ties among countries, economic agents have more reasons to be vigilant of for- eign economic policy....

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....

We study the effects of permanent and temporary income shocks on precautionary saving and investment in a ""store-or-sow"" model of growth. High volatility of permanent shocks results in high precautionary saving in the safe asset and low investment, or a ""volatility trap."" Namely, big savers...

Using the between-sector variation in income as a new measure of economic uncertainty, this paper proposes simple models and supportive empirical evidence for the causal relations between economic uncertainty and government size in the open economy setting. Key empirical findings include: (1) a...
