Introduce the concept of a vector autoregression VAR. The notion of an autoregressive distributed lag ADL is also introduced here. It may be that the interest rates are near unit root processes. There are several important points to note: The variables inf and dlip were generated as: Estimate urate as an AR 2 process including an intercept. To obtain the variance decompositions, from var01, select Variance Decompositions from the View tab. As can be seen from the output above, the Lag length was Automatic selection based on the t-statistic option using Maximum lags of 8.
XLS to perform the following: Impulse response functions are used to show the effects of shocks to year and 3-year rates on short-term rates. In Example 1, the student wants to estimate a demand for money function. Description Applied Econometric Time Series, 4th Edition demonstrates modern techniques for developing models capable of forecasting, interpreting, and testing hypotheses concerning economic data. Once you abandon the linear framework, it is necessary to select a specific nonlinear alternative. Instead of reading in the data, the following indicates how I generated the series: The student estimates the three interest rates as a VAR. To estimate the GAR model, from the Quick tab, estimate the regression:
The file also contains the recursive estimates, the recursive residuals and the cusums.
If you have not already done so, download tije manual from the Estima Estima. The Blanchard—Quah decomposition is illustrated using real and nominal exchange rates.

Develop the Johansen full-information maximum likelihood cointegration test. From the Quick tab, estimate the equation: The presence of unit roots in the interest rate series is mixed.
A common economefric is that it is possible to determine whether or not a series is stationary by visually inspecting the time path of the data. To reproduce the results, open tbill and from the View opt select Unit Root Test. Characteristic Roots, Stability, and Rank Appendix 6. The series are quarterly averages over the period Use the instructions above to make the residual series called resid01 that are reported in the TABLE residuals.
Increasing the magnitude of the AR 1 coefficient from 0. The Engle—Granger method is illustrated using simulated data.

Be sure to include a time trend. Unlike the real GDP data used in the text, the date in this file begins in Q1. The error terms are: Student View Student Companion Site. Some students will have a keen interest in financial econometrics. As can be seen from the output above, the Lag length was Automatic selection based on the t-statistic option using Maximum lags of 8.
On the Cointegration tab use option 2 constant in the cointegrating vector only. You can use Figures M and M below for further emphasis.

Chapter 2 discusses the important issue of combining multiple univariate forecasts so as to reduce overall forecast error variance. Note that the file contains the series y1, y2, and y3. For part c of the question, repeat using the other interest rates as the dependent variables.
Ebders variables are cointegrated 0 0. You can add this document to your saved list Sign in Available only to authorized users. Introduce intervention analysis and transfer function analysis.
The following programs will produce the indicated results. Equation contains the estimates of the M-TAR error-correction model. In VAR Specification, select Vector Error Correction and use 7 lags and on the Cointegration tab use option 2 constant in the cointegrating vector only.

For now, note the dummy variables econometrci be generated using: The relationship among the variables should be analyzed using innovation accounting impulse response functions and variance decomposition methods. You can also check for parameter instability and structural change using the methods discussed in Section Apply the Dickey—Fuller tests to U. I use these same overheads to explain why unit root tests have very low power. Why is there a problem in estimating the first-difference using the BoxJenkins methodology?
XLS to perform the following: Wwlter the dialogue box Test type select Augmented Dickey-Fuller. I work through one of these questions in the classroom and assign the other two for homework. The file contains the variable s generated as:
