Voting Methods
Beyond what you
reviewed in the required and recommended readings this week; different voting
methods are used to decide elections worldwide. Some countries, like Brazil,
elect their president using a two-round system, which is equivalent to the
instant runoff voting method. Other countries, like Mexico, use what is known
as the first-past-the-post system, which is equivalent to the plurality method.Research the
different electoral systems used worldwide and share a specific example.
Compare this country’s electoral system with the voting methods we examined in
this module. Based on fairness criteria, discuss your thoughts about the
fairness of this system.Your initial
post is due Thursday by midnight. A minimum of two follow up posts to your
classmates are due Sunday by midnight. Draw on lecture material and required
readings as you construct your post. Post your initial response early and check
back often to continue the discussion. Be sure to respond to your peers’ and
instructor’s posts, as well.Requirements

Aberystwyth University Forecasting Models for The Rate of Inflation Analysis
Experiential Learning - Forecasting models for the rate of inflation Data The variable PCEP is the price index for personal consumption expenditures from the U.S. National Income and Product Accounts (NIPA). In this hands-on exercise you will construct forecasting models for the rate of inflation, based on PCEP. For this analysis, use the sample period 1963:Q1–2012:Q4 (where data before 1963 may be used, as necessary, as initial values for lags in regressions). Use the QLR test with 15% trimming to test the stability of the coefficients in the AR(2) model for “the change in inflation” . Is the AR(2) model stable? Explain. Compute the (annualized) inflation rate,Plot the value of Infl from 1963:Q1 through 2012:Q4. Based on the plot, do you think that Infl has a stochastic trend? Explain. Double click in the table below to access to the excel table. Yes, It’s going upward before 1980 and going down afterwards. Its randomly determined. Compute the first four autocorrelations of Plot the value of Infl from 1963:Q1 through 2012:Q4. The plot should look “choppy” or “jagged.”Explain why this behavior is consistent with the first autocorrelation that you computed in part (i) for . Infl 0.823-0.2860.748-0.4420.7190.0920.661-0.00 Compute Run an OLS regression of on . Does knowing the change in inflation this quarter help predict the change in inflation next quarter? Explain.Estimate an AR(2) model for Infl. Is the AR(2) model better than an AR(1) model? Explain.Estimate an AR(p) model for . What lag length is chosen by BIC? What lag length is chosen by AIC?Use the AR(2) model to predict “the change in inflation from 2012:Q4 to 2013:Q1”-that is, predict the value of Use the AR(2) model to predict “the level of the inflation rate” in 2013:Q1—that is, . Use the ADF test for the regression in Equation (14.31) with two lags of to test for a stochastic trend in .Is the ADF test based on Equation (14.31) preferred to the test based on Equation (14.32) for testing for stochastic trend in ? Explain.In (i) you used two lags of . Should you use more lags? Fewer lags? Explain.Based on the test you carried out in (i), does the AR model for contain a unit root? Explain carefully. (Hint: Does the failure to reject a null hypothesis mean that the null hypothesis is true?) Using the AR(2) model for with a sample period that begins in 1963:Q1, compute pseudo out-of-sample forecasts for the change in inflation beginning in 2003:Q1 and going through 2012:Q4. That is, compute:Are the pseudo out-of-sample forecasts biased?That is, do the forecast errors have a nonzero mean?How large is the RMSFE of the pseudo out-of-sample forecasts? Is this consistent with the AR(2) model for estimated over the 1963:Q1–2002:Q4 sample period?There is a large outlier in 2008:Q4. Why did inflation fall so much in 2008:Q4? (Hint: Collect some data on oil prices. What happened to oil prices during 2008?)
