The Exchange Rate and Monetary Policy in Kenya.

The paper assesses whether the exchange rate is affected by monetary policy and whether these effects are permanent or transitory. In addition, the paper takes the position that once the exchange rate regime has been chosen it determines the flexibility of monetary policy. The real exchange rate is decomposed into cyclical and permanent components. Causality tests are performed between several measures of monetary shocks (consistent with other empirical works) and the cyclical component of the real exchange rate. The results show that excess money supply predict each other with the cyclical movements of the real exchange rate. In the second stage a model of nominal exchange rate is estimated. Since we find cointegration, the model is estimated with first-difference of the variables, the cyclical component of the real exchange rate and the cointegrating vectors. The results show that the nominal exchange rate over the period is determined by real income growth, the rate of inflation, money supply growth, the cycles in the real exchange rate movements, the cointegrating vectors and shocks. The first cointegrating vector is normalized with money supply and the second with nominal exchange rate; they show a differential in adjustment speeds reflecting the fact that the nominal exchange rate movements responds quickly to one type of disequilibrium and slowly to the other. For the first vector the adjustment speed is consistent with an exchange rate policy that accommodates monetary disequilibrium in order to protect reserves or with a market determined exchange rate responding to excess money supply. This vector portrays the underlying monetary responses during different exchange rate regimes. In addition the results from causality tests between the official exchange rate and the parallel rate show that even though the parallel market was illegal, the central bank in determining the crawl (during the crawling rate regime) took into account the value of the cur...
