This paper empirically examines the relationship among saving, investment and economic growth in
Lesotho for the period 1970 to 2012, with a view to contributing to the body of literature on this topic
and informing economic policy design in Lesotho. Using autoregressive distributed lag (ARDL) bounds
testing approach to cointegration and vector error correction model (VECM) based Granger causality
test; the paper finds the existence of cointegration among the variables and short-run causal flow from
economic growth to saving. However, in the long-run, the paper provides evidence of Granger causality
from saving to economic growth. Furthermore, the results indicate the existence of short-term and
long-term Granger causality from saving to investment in addition to short-term and long-term causal
flow from investment to economic growth. The findings not only suggest that saving precedes and
drives short-term and long-term capital accumulation but also contributes to long-term economic
growth in Lesotho. In addition, there is empirical evidence for investment-led growth. Therefore,
increased capital accumulation is likely to contribute to enhancing sustainable economic growth.
Key words: Savings, investment, economic growth, ARDL bound testing, Lesotho, Granger causality.
INTRODUCTION
Economic growth is a key indicator of societal progress.
In this regard, countries around the globe strive to
achieve higher economic growth in order to provide
higher standard of living for their citizens. Nevertheless,
low saving rates have been identified as one of the major
growth-inhibiting factors among countries in the world,
especially in developing countries such as Lesotho. This
is because as postulated by the classical economists,
increased saving is likely to lead to increased investment,
which is a key to promoting long-run economic growth.
Therefore, a sound understanding of the interaction
among saving, investment and economic growth in a
country’s economy is important for the achievement of
macroeconomic policy conducive to sustainable
economic growth and hence higher standard of living of
citizens.
There are numerous empirical studies in the literature
that examine the direction of causality among saving,
investment and economic growth. This is on account of
the important policy implications that can be derived from
this relationship regarding the course of action that can
be done to accelerate economic growth since saving and
