In this question, you will test relative purchasing parity (PPP) using the data. Use yearly
data from FRED website
from 1971 to 2020: (i) The Canadian Dollars to U.S. Dollar Spot
Exchange Rate (ER) (ii) Consumer price index for Canada (CAN_CPI), and (iii) Consumer price
index for the US (US_CPI). Inflation is measured by the consumer price index (CPI). The relative
PPP equation is:
AE CAN$/US$
ECAN$/US$
=
π CAN - πUS
Submit the Excel sheet that you worked on.
1. First, compute the percentage change in the exchange rate (left-hand side of the equation).
Caculate the variable for each year from 1972 to 2020 in Column E (named Change_ER) of
the Excel sheet. For example, for 1972, compute
E3: (B3-B2)/B2).

From the analysis of Joy's various outlets, it was found that the demand curve follows this pattern: Q=200-300P+1201 +657-250A +400A; where Q = number of cups served per week P = average price paid for each cup I = per capita income in the given market (thousands) Taverage outdoor temperature A competition's monthly advertising expenditures (thousands) = A; = Joy's own monthly advertising expenditures (thousands) One of the outlets has the following conditions: P = 1.50, I = 10, T = 60, A₁ = 15, A; = 10 1. Estimate the number of cups served per week by this outlet. Also determine the outlet's demand curve. 2. What would be the effect of a $5,000 increase in the competitor's advertising expenditure?

- The Compute Company store has been selling its special word processing software, Aceword, during the last 10 months. Monthly sales and the price for Aceword are shown in the following table. Also shown are the prices for a competitive software, Goodwrite, and estimates of monthly family income. Calculate the appropriate elasticities, keeping in mind that you can calculate an elasticity measure only when all other factors do not change (using Excel). For example, price elasticities, months 1-2.

Based on the five-year history, we see that dividends per share grew at a compound annual growth rate of 4.86% $5.96 (1/5) CAGR = $4.70 − 1 = (1.2681)0.20 − 1 = 1.0486 - 1 = 0.0486 = 4.86% - - What should be the 2023 dividend based on these values?arrow_forward4. The data set BWGHT.DTA contains data on births to women in the United States. Two variables of interest are the dependent variable, infant birth weight in ounces (bwght), and an explanatory variable, average number of cigarettes the mother smoked per day during pregnancy (cigs). The following simple regression was estimated using data on n=1,388 births: bwght=119.77 - .514 cigs (i) What is the predicted birth weight when cigs = 0? What about when cigs=20 (one pack per day)? Comment on the difference. (ii) Does this simple regression necessarily capture a causal relationship between the child's birth weight and the mother's smoking habits? Explain. (iii) To predict a birth weight of 125 ounces, what would cigs have to be? Comment. (iv) The proportion of women in the sample who do not smoke while pregnant is about .85. Does this help reconcile your finding from part (iii)?arrow_forward
