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...

China’s household saving rate has increased markedly since the mid-1990s and the age-savings profile has become U-shaped. We find that rising income uncertainty and pension reforms help explain both of these phenomena. Using a panel of Chinese households covering the period 1989-2006, we...

The relationship between current account developments and changes in the macroeconomic environment remains a key issue in open economy macroeconomics. This paper extends the standard intertemporal optimizing model of the current account to incorporate the effects of macroeconomic uncertainty on...

This paper investigates the emerging global landscape for public-private co-investments in infrastructure. The creation of the Asian Infrastructure Investment Bank and other so-called 'infrastructure investment platforms' are an attempt to tap into the pool of both public and private long-term...

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...

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...

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...

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...

India's real GDP growth slipped substantially after the North Atlantic financial crisis. Return to a sustained high growth trajectory is feasible but it will need much more focused attention to the revival of manufacturing and to the acceleration of investment in transport and infrastructure....
