A Research Examination of Covered-Uncovered Interest Rate Parity and the Purchase Power Parity (PPP) hypothesis: Applications in MATLAB, RATS and EVIEWS Eleftherios Giovanis

Seminar paper from the year 2008 in the subject Business economics - Investment and Finance, grade: 95.00%, , language: English, abstract: This project examines in the first part the covered and uncovered interest parity between US dollar and Swiss Franc. We present simple summary statistics, unit root tests, deviations from covered interest parity, regression analysis, threshold autoregression and exponential transition autoregression. Then we present the uncovered interest parity and, as in the case of covered interest parity, we apply some tests to examine if it's valid. We apply Johansen cointegration tests between spot and forward rates, but also between forward premia and interest rates differentials and we test if there is a cointegration equation and we estimate the vector error correction model. After this procedure we present the impulse responses. Next we test if there is a threshold cointegration relation between the above variables. Finally in the last section we apply a dynamic OLS (DOLS) estimation with Newey-West HAC standard errors. In the second part the purchasing power parity (PPP) hypothesis is examined with a similar methodology followed, where additionally we present a long span study, unit root tests allowing for structural breaks in data, panel unit root tests as also Markov switching regime autoregressive model is examined in the category of the non linear models
