A key issue in the recent empirical macroeconomics has been the high growth experience of
the developing Asia. Apart from the pre-Asian crisis experience, the quick recovery of the
East Asian tigers and cubs to the high-growth trajectory, and the entry of China and India in
the high growth club, have all been areas of interest of international macro chronicle. But
why did Asia grow so fast? One of the variables that is often emphasized in this context has
been the high saving rates of developing Asia. After all, growth of output of any economy
depends on capital accumulation, which, in turn, requires investment and an equivalent amount of savings to match it (Thirlwall, 1999). Two of the most important issues in
development economics, and for developing countries are, thus: (a) How to stimulate
investment? and (b) How to bring about an increase in the level of saving to fund increased
investment? Interestingly, in the Solow (1956) variety of neoclassical growth model, an
increase in savings ratio (i.e., savings-GDP ratio) is capable of generating higher growth
only in the short run during transition between steady states, while the long-run growth
being determined by the demographic factors. In the more recent literature on endogenous
growth models, higher saving can lead to higher capital accumulation and consequently
higher long-run growth rates (Lucas, 1988).
Difference in saving rates across countries, thus, continues to be an interesting question
haunting the economists and policy makers alike. Consider the following statement from the
recent work of Akerlof and Shiller (2009, p. 118):
It should be no surprise that the rate of saving is highly variable across countries.
Some countries have net saving of a third of their national income; some have negative
net savings.
In this context, the high saving rates of Asian economies have attracted much attention.
Illustratively, in 2007, while China saved more than 50% of its GDP, the saving rate of the
US was slightly above 10%. Why is it so? Are the Asians by nature thrifty? Is it something
anthropological or cultural? Or, since the social security in many of the Asian countries is
not so great, are people forced to save more? Does the high job insecurity in some economies
force people to save? Alternatively, is it the demographic structure of Asia that induces
people to save more? These questions are often raised in popular media and academic literature
alike.
The issue of high saving by the Asian countries has another dimension. The hypothesis
of ‘global savings glut’, as initiated by Bernanke (2005), views excess saving of Asian
emerging market countries as the major cause of the US current account deficit. From this
perspective, the US external imbalance is a problem made overseas. Thus, it is amenable to
a solution only in the longer term, as better developed financial systems could mitigate this
excess saving problem.1
It is in this context, the present paper looks into the saving experience of developing Asia
empirically. The main thrust of this paper is that instead of looking at a particular economy,
the paper looks into this empirical question at a panel setting for a group of high-saving
economies in Asia, covering the period 1990-2007.
The rest of the paper is organized as follows: it gives a brief survey of the literature,
followed by some of the stylized facts on Asian saving. Subsequently, it discusses the empirical results on determinants of Asian saving, and finally provides conclusion with possible
directions for future research.
