Exchange rate pass-through therefore is the effect positive or negative of exchange rates on import and export prices, consumer prices or inflation, investments as well as trade volumes.
Engel and Rogers established that crossing the US-Canada border can considerably raise relative price volatility and that exchange rate fluctuations explain about one-third of the volatility increase. That is US-Canada border is an important determinant of relative price volatility even after making due allowance for the role of distance.
Parsley and Wei confirmed previous findings that crossing national borders adds significantly to price dispersion. The demand for and supply of money are the key determinants of exchange rates. Interest Rate Parity is an important concept that explains the equilibrium state of the relationship between interest rate and exchange rate of two countries. The foreign exchange market is in equilibrium when deposits of all currencies offer the same expected rate of return.
The condition that the expected returns on deposits of any two currencies are equal when measured in the same currency is called the interest parity condition. It implies that potential holders of foreign currency deposits view them all as equally desirable assets, provided their expected rates of return are the same.
Given that the expected return on say US dollar deposits is 4 percent greater than that on Ghana cedi deposits, all things being equal, no one will be willing to continue holding Ghana cedi deposits, and holders of Ghana cedi deposits will be trying to sell them for US dollar deposits.
There will therefore be an excess supply of Ghana cedi deposits and an excess demand for US dollar deposits in the foreign exchange market Krugman et al. An important theory of the relationship between inflation rate and interest rate is the Fisher effect; sometimes referred to as the Fisher hypothesis by Irvin Fisher.
Fisher proved mathematically that the nominal interest rate is equal to the real interest rate minus the expected predicted inflation rate. The Fisher effect simply explains for example that; if the nominal interest rate is say 50 per cent for a given period, and the predicted inflation rate during that same period is 20 per cent, then the real interest rate is 30 per cent. The movement in short term interest rates primarily reflects fluctuation in expected inflation, which in effect has a predictive ability for future inflation Mishkin and Simon The primary objective of the Central Bank of Ghana is to maintain stability in the general level of prices Bank of Ghana Act It must be noted that price stability alone might not be enough for a healthy economy.
Several studies have been conducted on modelling inflation rates in Ghana, and majority of these used the constant variance assumption model. Although Mbeah-Baiden used non-constant variance models to model inflation rates in Ghana, his work only considered a univariate analysis of inflation rates.Interest Rates and Exchange Rates, James Tompkins
In the developed countries where a number of the researchers have modelled financial data series using Multivariate Generalized Autoregressive Conditional Heteroscedastic MGARCH models, none has modelled the co-movements of inflation rates, exchange rates and interest rates.
A researcher can apply all these models on data series and the best model is chosen based on the performance of the model using a criterion. The latter regimes would have to implement an exchange rate target to influence their inflation, as none of the other instruments are available to them.
Credibility[ edit ] The short-term effects of monetary policy can be influenced by the degree to which announcements of new policy are deemed credible. But if the policy announcement is deemed credible, inflationary expectations will drop commensurately with the announced policy intent, and inflation is likely to come down more quickly and without so much of a cost in terms of unemployment.
Thus there can be an advantage to having the central bank be independent of the political authority, to shield it from the prospect of political pressure to reverse the direction of the policy. But even with a seemingly independent central bank, a central bank whose hands are not tied to the anti-inflation policy might be deemed as not fully credible; in this case there is an advantage to be had by the central bank being in some way bound to follow through on its policy pronouncements, lending it credibility.
Contexts[ edit ] In international economics[ edit ] Optimal monetary policy in international economics is concerned with the question of how monetary policy should be conducted in interdependent open economies.
The classical view holds that international macroeconomic interdependence is only relevant if it affects domestic output gaps and inflation, and monetary policy prescriptions can abstract from openness without harm. The policy trade-offs specific to this international perspective are threefold: Second, another specificity of international optimal monetary policy is the issue of strategic interactions and competitive devaluations, which is due to cross-border spillovers in quantities and prices.

Even though the gains of international policy coordination might be small, such gains may become very relevant if balanced against incentives for international noncooperation. Even though the real exchange rate absorbs shocks in current and expected fundamentals, its adjustment does not necessarily result in a desirable allocation and may even exacerbate the misallocation of consumption and employment at both the domestic and global level. This is because, relative to the case of complete markets, both the Phillips curve and the loss function include a welfare-relevant measure of cross-country imbalances.
Consequently, this results in domestic goals, e. In developing countries[ edit ] Developing countries may have problems establishing an effective operating monetary policy.

The primary difficulty is that few developing countries have deep markets in government debt. The matter is further complicated by the difficulties in forecasting money demand and fiscal pressure to levy the inflation tax by expanding the base rapidly.
In general, the central banks in many developing countries have poor records in managing monetary policy. This is often because the monetary authority in developing countries are mostly not independent of the government, so good monetary policy takes a backseat to the political desires of the government or are used to pursue other non-monetary goals.

For this and other reasons, developing countries that want to establish credible monetary policy may institute a currency board or adopt dollarization. This can avoid interference from the government and may lead to the adoption of monetary policy as carried out in the anchor nation.

Recent attempts at liberalizing and reform of financial markets particularly the recapitalization of banks and other financial institutions in Nigeria and elsewhere are gradually providing the latitude required to implement monetary policy frameworks by the relevant central banks. Transparency[ edit ] Beginning with New Zealand incentral banks began adopting formal, public inflation targets with the goal of making the outcomes, if not the process, of monetary policy more transparent.
The Bank of England exemplifies both these trends. It became independent of government through the Bank of England Act and adopted an inflation target of 2.
