It is widely hypothesised that sound macroeconomic policies promote gr
owth by providing a more secure environment for private sector investm
ent decisions. This proposition is tested for a cross-section of devel
oping countries over the period 1980-90 using a variety of measures of
the quality of macroeconomic management. The evidence suggests that g
ood macroeconomic management is associated with faster growth for a gi
ven rate of investment. It is less clear that the volume of investment
is significantly affected. There is little evidence of non-linearitie
s. The results are robust to an extension of the data period back to 1
972.
