Abstract:
The core objective of this dissertation is to analyze the transmission mechanism of monetary
policy in the presence of incomplete pass-through, the existence of the informal financial sector
and time-varying financial frictions in Pakistan. These issues manifest some of the
characteristics of the financial sector of Pakistan, which are pertinent for the effectiveness of
the monetary policy. This study is a collection of three essays that utilize context-specific
methodologies embedded in a Dynamic Stochastic General Equilibrium (DSGE) setting for
both, closed and open economy frameworks. In the first essay, the monetary transmission
mechanism has been analyzed in the presence of incomplete interest rate pass-through and
cost-channel for exogenous monetary policy shock and endogenous movements in policy rate
arising because of other financial, nominal, and real shocks in the economy. The study found
that the degree of interest rate pass-through depends on the nature of the shock hitting the
economy; while the cost channel exists only for monetary and financial shocks. A weak tradeoff
has been recorded between the degree of pass-through and the cost channel of monetary
policy. Interestingly, for some shocks banks have been found to shelter firms from monetary
policy shock by smoothing retail rates but for other shocks, they do not do so. Instead, banks
have pursued profit motives even within the economic stabilization goals of the monetary
policy. In the second essay, the interaction between formal and informal financial sectors has
been analyzed in the face of domestic and foreign monetary policy shocks. The welfare and
resource distribution in the financial sector is also examined to ascertain the interlinkages
between these sectors. The study finds that the presence of the informal financial sector
significantly hampers the effectiveness of domestic monetary policy and mitigates the impact
of the foreign monetary shock. It has also been found that welfare and resource distribution
occurs due to informal financial activities. The third essay investigated the finance-growth
nexus by constructing a financial liberalization index incorporating time-varying financial
frictions, which is a manifestation of the de-jure financial liberalization process. For
examining the impact of financial liberalization on growth, the Solow-Swan growth model has
been extended to include the financial liberalization index. By incorporating the de-jure
financial liberalization index, the growth-finance linkages confirmed that financial deepening
and inclusiveness provide momentum to economic growth in both, the short- and long-run.
Moreover, the impact of time-varying financial frictions is also examined. The empirical
findings have confirmed that moving towards a more liberalized financial system by reducing
rigidities and expediting an effective reform process offers optimistic prospects for economic
growth and stabilization in Pakistan
