Estimating Standard Error of Inflation Rate in Pakistan: A Stochastic Approach

“The answer to the question what is the mean of a given set of magnitudes cannot in general be found, unless there is given also the object for the sake of which a mean value is required. There are as many kinds of average as many purposes; and we may almost say in the matter of prices as many purposes as many writers.” Edgeworth (1888). We estimate standard errors (S.Es.) of month on month and year on year inflation in Pakistan based on data for the period of July 2001 to June 2010 using the stochastic approach as well as extended stochastic approach to index numbers. We develop a mechanism to estimate S.E. of period average headline inflation (rate) using these approaches. This mechanism is then applied to estimate S.Es. of 12-month average rate of inflation in Pakistan for July 2003 to June 2010. The systematic changes in the relative prices of different groups in the CPI basket for Pakistan are also estimated. The highest (positive) relative price inflation occurred in ‘food, beverages and tobacco’ group and the lowest (negative) for ‘recreation and entertainment’ group, during fiscal years 2001 to 2010.

Procyclical Monetary Policy and Governance

Weak governance adversely affects firm’s net worth and consequently the value of its collateral. This negative impact on the collateral reduces the external credit available for importing inputs constraining potential output. As a result, a stronger procyclical monetary policy stance is adopted for protecting the exchange rate and hence arresting the degradation in the collateral constraint.Collateral Constraints; Governance; Monetary Policy

Central banking and monetary management in islamic financial environment

Continuous growth in Islamic finance calls for studying the framework in which the monetary policy maker (i.e., central bank) performs its functions. Central banks in Muslim countries are using various instruments for monetary policy purpose including interest rate. As a result, Islamic financial institutions (IFIs) are facing issues in benchmarking the price of financial instruments. Acceptable solution to benchmarking lies in the presence of a real economic activity in the base of any proposal and its feasibility for business performance when put against conventional banking. This paper presents empirical evidence of statistical equivalence of nominal GDP growth rate and official interest rate for ‘advanced,’ ‘all,’ and some Muslim countries. We propose nominal GDP growth rate as benchmark for pricing domestic financial transactions of IFIs as well as for pricing external bilateral/ multilateral loans. The paper also suggests nominal income targeting as monetary policy regime and provides a liquidity management mechanism for banking system in Islamic financial environment

Pass-Through of SBP Policy Rate to Market Interest Rates: An Empirical Investigation

Market based implementation of monetary policy embeds a swift and complete pass-through of changes in policy rate to market interest rates. This impacts the lending and deposit rates (retail rates) of the banking system. Incomplete and slow pass-through impairs the effectiveness of monetary policy transmission mechanism. This study estimates the degree and the speed of interest rate pass-through in case of Pakistan. Monthly data on State Bank of Pakistan (SBP) policy rate, money market rates and banks’ retail lending/deposit rates from July 2001 to August 2011 is used to estimate an unrestricted autoregressive distributed lag (ARDL) model. The standard ARDL model allows for the estimation of an error correction model, which helps in differentiating short run impact of changes in policy rate from its long run impact on the banks’ lending rates. The results indicate that while there is a swift pass-through from the policy rate (T-bill rates and overnight rate) to money market rate, the impact of changes in money market rates on the bank deposit rates is not only sluggish, but also incomplete. However, banks’ lending rates on fresh loans are more responsive to changes in money market rates as the banks have the luxury to take into account the changes in opportunity cost of funding

Intrinsic Inflation Persistence in a Developing Country

This study estimates degree of intrinsic inflation persistence in Pakistan using aggregate price index, group level price indices, and individual commodity prices. We find no evidence of a unit root in (MoM) inflation at any level, except for house rent. Using monthly data from 1959 to 2011 we find that the estimate of (overall) inflation persistence is 0.16, which is low but significant. During 2001-2011 (overall) inflation persistence is insignificant. Food inflation does not exhibit any persistence during the last decade. However, the degree of persistence is very high (0.80) and significant for core inflation (NFNE), which weakens slightly (to 0.69) when we account for commodities price shock of 2008. At micro level, the estimated degree of inflation persistence for various groups is found to be relatively higher, in almost 60 percent of the cases, compared to corresponding degree of persistence at aggregate level. This may be because in micro analysis we consider only those commodities for which the estimated degree of inflation persistence is significant

Formal sector price discoveries: preliminary results from a developing country

We present preliminary results of 1086 structured interviews about price setting behavior of the formal firms in the manufacturing and services sector of Pakistan. Our key discoveries are that frequency of price change is considerably high in Pakistan, lowering the real impact of monetary policy. Price rigidity is explained mainly by firms caring about relative prices and the persistence of a given shock. The exchange rate and cost shocks are more important than financial and demand shocks for both setting prices and also the readiness with which these pass-through to the economy. Large firms change prices more frequently compared to smaller firms. Formal sector firms, especially medium sized firms, interact more with informal sector firms through the demand and supply channels. Formal firms highly connected with the informal sector have lower frequency of price changes. Formal sector firms hold lack of taxes and compliance with tax regime, i.e. enforcement, as the main reasons for the existence of the informal sector

A small-size macroeconometric model for Pakistan economy

This paper is part of efforts to develop macroeconometric model for Pakistan (MMP). This paper is an initial attempt to develop a small size macroeconometric model to foresee the effects of monetary policy through forecasting and simulations. We present the basic structure of macroeconometric model for Pakistan. This is a small-size model comprising 17 equations, out of which 11 are behavioral equations while the rest are either identities or definitional equations. OLS method is used to estimate the behavioral equations by using annual data from FY73-FY06. We provide the estimation results and results of policy simulations to quantify the impact of shocks to various exogenous variables
