Use the dаtа set here fоr this questiоn. The dаta are annual оbservations from 1990 through 2020. The variables of interest in the data set are: LNTRDEF: the natural log of Canada's trade deficit with Mexico; in each of those years Canada's imports from Mexico exceeded its exports to Mexico. LNDGDP: the natural log of (Canada's per capita GDP minus Mexico's per capita GDP); in each of the years this is positive. LNEXMXCA: the natural log of the exchange rate between Canada and Mexico (Mexican currency per unit of Canadian currency). Additional notes are below and these may be of interest when you are reviewing the key. Given the time constraint during the exam it may be best to skip them until after the key is available. a) What is the mean for LNTRDEF? [a_15pt84]. b) The standard deviation for LNEXMXCA is [b_pt604]. c) Construct a histogram of LNTRDEF. T/F: the distribution appears to be roughly bell shaped. [c_FALSE]. d) Regress LNTRDEF on LNDGDP and LNEXMXCA. You are regressing the log of Canada's trade deficit on the log of the difference in the per capita GDP and the log of the exchange rate. What percentage of the variation in the dependent variable does your model explain? [d_93pt68]. e) T/F: the coefficient on LNDGDP is statistically significant at the 0.1 level. [e_FALSE]. f) T/F: the coefficient on LNEXMXCA is statistically significant at the 0.01 level. [f_TRUE]. g) Conduct the test for normality which we covered in this course. Use the standardized residuals. That is, test whether or not the standardized residuals are normally distributed. The p-value for this test is [g_pt604]. h) Based on the result of your test and assuming an alpha value of 0.1, do you conclude that the residuals are normally distributed or not normally distributed? [h_normal]. i) Obtain the default residual plots in R. Is there an observation that appears to be potentially influential in one of those plots? [i_yes]. j) Find the DFITS value for the observation that appears to be influential. If no observation appears to be influential then choose that answer. [j_neg1pt98]. k) For 2021 the exchange rate was 16.18 Mexican Pesos per Canadian $. For 2021 Canada's per capita GDP was $41,942.2 greater than Mexico's; values for 2022 were not available at the time this test was made. Take the natural logs of those values to obtain LNEXMXCA and LNDGDP and then use your model to find the predicted value for LNTRDEF for 2021. The value is [k_16pt89]. l) Construct a 90% prediction interval for the scenario above, scenario (k). The 90% prediction interval is [l_16pt5to]. ## Notes for follow-up after the exam. ## Net exports for Canada with its trading partner Mexico are slightly modified from the data available from WITS (register with wits.worldbank.org to obtain the actual data). This is CANNXMOD in the file. Per capita GDP data are from FRED (compiled from the World Bank); PCAGDPCA and PCAGDPMX in the file. The exchange rates are also derived from data at FRED; DEXCAUS and DEXMXUSFF are the exchange rates with the US and they were used to construct EXMXCA which is the exchange rate between Canada and Mexico as Pesos per CAD. Net exports are related to the exchange rate in a negative way. We expect that if the Canadian dollar appreciates against the Mexican peso then Canadas net exports with Mexico will decrease and its trade deficit will increase. "Changes in relative costs because of exchange-rate fluctuations also influence relative prices and the volume of goods traded among nations... [currency] appreciation tends ... induce a decrease in the quantity of [exports] ... similarly, the [currency] appreciation leads to an increase in ... imports." (Carbaugh, International Economics, 18e 2022 Cengage, page 377). Similarly, as Canadians' incomes increase relative to that of Mexicans' incomes then, assuming both countries produce normal (as opposed to inferior) goods, we might expect Canadian net exports to Mexico to decrease and its trade deficit to increase. As Canadians have more money they buy even more goods from Mexico.
