Purpose: Public physical infrastructure development has fairly large
impacts on private sector investment decisions and through this; it can affect
economic performance (growth). The current study intends to explore the
course in which public infrastructure affects private sector investment in
Pakistan and whether there exist long run equilibrium between them or not.
Time series annual data from 1972 to 2015 has been employed. Instead of
using a single infrastructure indicator, the study has constructed a
multidimensional composite index through principal component analysis
(PCA). Real gross fixed capital formation is used as the proxy of private
sector investment. The long run relationship is determined by Johansen’s
co-integration technique after checking for the order of integration. The
empirical evidence shows that physical infrastructure availability is
positively and significantly affecting private sector investment decisions. In
addition, credit to private sector, per capita GDP, work force and inflation
rate are positively and significantly affecting private investment. Further,
private investment is sensitive to public physical infrastructure availability
not only in long run but also in short run. A statistically significant and
negative ECT (-1) term confirms the long run relationship and convergence
towards equilibrium in case of Pakistan. Findings of the study show that
public physical infrastructure services endorse the private investment both
in the long run and the short run.
