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 of...

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...

This paper highlights that real interest rates in Brazil have declined substantially over time, but are still well above the average of emerging market inflation targeting regimes. The adoption of an inflation-targeting regime and better economic fundamentals (reduction in inflation volatility...

In coming decades, China will undergo a notable demographic transformation, with its old-age dependency ratio doubling to 24 percent by 2030 and rising even more precipitously thereafter. This paper uses the permanent income hypothesis to reassess national savings behavior, with greater...

Are generational accounts informative about the effect of the budget on the intergenerational distribution of resources and on aggregate saving? First, the usefulness of generational accounts lives or dies with the strict life-cycle model of household consumption. Second, even if the life-cycle...

We study, both empirically and quantitatively, the role of savings and the labor supply inself-insurance channels over the life cycle when one faces not only idiosyncratic income risks, but also changes in longevity risk and pension benefits. We pick China as a case study since China has...

Using cross-country national accounts and firm-level data, we document a broad-based trend in rising gross saving and net lending of non-financial corporates across major industrialized countries over the last two decades, though most pronounced in countries with persistent current account...

China's high national savings rate-one of the highest in the world-is at the heart of its external/internal imbalances. High savings finance elevated investment when held domestically, or lead to large external imbalances when they flow abroad. Today, high savings mostly emanate from the...

This paper studies the effect of demographic change on national saving, global interest rates, and international capital flows, focusing on the role of the public pension system. We develop a small open economy overlapping generations model to illustrate the channels through which demographic...

Building on the evolving literature on the topic, this paper reviews the relationship between demographics and long-run capital flows in both theory and in the data. For this purpose, we develop a two region overlapping generations model where countries differ in their population growth and...
