Abstract:
The thesis consists of four independent essays on investment behavior in
Pakistan. These include (i) Investment Trends and Policies in Pakistan; (ii) Political and
Economic Uncertainty and Investment Behavior in Pakistan (iii) Private, Public and
Foreign Investment Nexus in Pakistan: An Empirical Analysis of Crowding-in/out
Effects; and (iv) Investment Behavior in Pakistan: A Sector-Wise Analysis of Private
and Public Investment.
The first essay surveys investment trends and policy framework for the
economy of Pakistan. The economic situation in Pakistan has endured many
fluctuations since independence in 1947. The situation is not different for the case of
investment patterns throughout the history of the country. In addition to that, the
country has been confronted with multiple policy changes such as nationalization,
denationalization, privatization etc. coupled with political instability. The study
analyzes the (i) trends of public, private domestic and foreign direct investments along
with trends of total investment and economic (GDP) growth; distribution of aggregate
investment; and (ii) sector-wise composition of private and government investments for
the time span 1959-60 to 2014-2015. The analysis reveals that over the period private
domestic investment has dominant share in total investment compared to public
investment and foreign direct investment. Sector-wise private investment composition
shows the dominant share of services over time. On the other hand, in case of sector
wise composition for the public investment the general government investment has
witnessed the rising trends over the years and emerged as a leading sector followed by
industry and services respectively.
The second essay examines the impact of macroeconomic uncertainty and
political (in) stability, controlling for other determinants of investment, on aggregate/total gross fixed investment in Pakistan. Autoregressive Distributed Lags
(ARDL) technique is used to analyse the investment behavior under uncertainty. The
study finds that political stability affects the aggregate investment significantly and
positively in the long-run. The impact of macroeconomic uncertainty on investment is
found to be negative and significant. Other findings are consistent with literature.
Analysis in the third essay aims to empirically explore the public, private
domestic and foreign direct investments nexus to figure out the direction and relative
strength of the relationship. Using the Vector Error Correction Model (VECM) the
interrelationship among the private domestic investment, public investment, foreign
direct investment (FDI) and Gross Domestic Product (GDP) is analysed. The results
show that all the three types of investments (private domestic, public and foreign direct)
are substituting (i.e. crowding-out) each other while these investments are robust
determinants of economic growth.
The fourth essay investigates the determinants of private sector investment in
major economic activities/categories viz. agriculture, industry and services and public
investment including general government investment for the Pakistan economy. The
models of private gross fixed investment in each sector and public investment are
developed in the light of relevant theoretical and empirical literature. Autoregressive
Distributed Lags (ARDL) modeling technique is applied for each case to analyze
investment behavior in Pakistan. The overall findings of the study are in line with
theoretical models as well as dynamics of the economy. The results reveal that the
accelerator model performs well for both private and public investments while the user
cost of capital is not significantly explaining private investment behavior. The behavior
across the sectors not only differs in terms of overall but also sector-specific
determinants. The findings also suggest the structural change process in investment
patterns for the Pakistan economy.
