Background
Monetary policy of Bangladesh concerns about inflation,
growth, exchange rate, interest rate and money supply (BB,
2016);
Contractionary policy shock increases real interest rate,
appreciates domestic currency, and decreases both inflationary expectations and output (Bhuiyan, 2013);
Increasing the policy interest rate decreases output, and
appreciates local currency and increases the price level
(Alam 2015);
Monetary policy plays a better role than fiscal policy in
accelerating the economic growth in Bangladesh (Maroney
et al, 2004; Hasan et al., 2016).
Background Contd.
For monetary policy transmission mechanism the
- utput decomposition technique:
explains the insight of economic traits, identifies the underlying effective procedures
- f the monetary policy shocks to the particular
real sectors (Angeloni et al. 2003; Fujiwara 2004; Phan
2014).
So far as I found, still there is no research about
this method for Bangladesh.
Research Question
What is the more effective channel between the
consumption and investment for the monetary policy transmission mechanism in Bangladesh?
Literature Review
Monetary policy affects the real economy mainly
through the interest rate and exchange rate
(Obstfeld & Rogoff, 1995);
In Bangladesh monetary policy shocks transmit to
the real output through both the interest rate and exchange rate, however, interest rate instantaneously responds to exchange rate (Bhuiyan
2013);
Exchange rate fluctuation affects the inflation in
Bangladesh (Akhtaruzzaman, 2005).
Literature Review Contd.
The investment channel is superior in the Euro
area, whereas, consumption channel plays the major role in the USA (Angeloni et al., 2003);
Investment channel
works better in Japan
(Fujiwara, 2004) and Australia (Phan 2014).
The household
spending is still the main contributor to real GDP growth in the USA
(Fischer 2016);
Data
Yearly data from 1973 to 2015 is used; Nine variables: the household consumption,
investment, import, GDP deflator, total bank credit and central bank’s policy rate are collected from IMF (2016) while exchange rate is from WB (2016);
“Other
GDP” (remaining) is calculated by deducting the consumption, investment and import from GDP;
India’s GDP data is also from IMF (2016).
Data Description
Trend of investment data (IMF, 2016) as a percentage
- f the GDP is almost same as central bank’s
historical data (BB 2016) available from the year 1989-90.
Consumption data (IMF, 2016) is on average 5
percent lower than the central bank's data (BB
2016), while for consistency, IMF’s data is used.
Consumption data usually contains some
seasonality effects; to address this issue and for easy interpretation, variables (except the interest rate) are transformed to the logarithmic form.
Data Description Contd.
The nature of the output decomposition data of
Bangladesh is quite different from Australia, Japan, and the USA's data;
The "other GDP" (after deducting “consumption”
and “investment”) component which is used in the literature is positive;
For Bangladesh, "other GDP" becomes negative
for some years with a very high standard deviation.
Negative value generates missing figures when
transforming in the logarithmic term, hence, another variable, the import (im) is used.
Methodology
and,
Two recursive (Christiano et al. 1999)VAR models
(Specification 1 & 2) are used to examine the sensitivity of the investment and consumption for both the interest and the exchange rate shocks.
Two non-recursive (Sims and Zha, 1998 and Kim
and Roubini, 2000) identification models (Specification 3 & 4) are also used by imposing restrictions on the contemporaneous parameters considering the conditions of the economy.
Methodology Contd.
The relationship between the reduced form errors and
the structural disturbances for specification-1 (S-1) would be shaped as the following matrix form:
Methodology Contd.
The structural matrix for the specification-4 (S-4) is
constructed as follows:
Methodology Contd.
Granger causality test confirms that exchange rate
shock is statistically significant (rejects the null hypothesis) for the fluctuation in the consumption and price level both at 0.1 percent significant level while for the total credit the null hypothesis is rejected at 10 percent significant level;
Considering the sample size and frequency one lag
is used following the SBIC. (Following Lutkepohl, 1985 and Enders, 2010)
Methodology Contd.
The models satisfy the stability condition as all the
eigenvalues lie inside the unit circle;
