- Each term (3 months) the current group of economics students completed a questionnaire as to how much they would spend on new purchases compared to how much they would save/pay off bills, if they suddenly and unexpectedly received a check for $1,000. The average MPC is shown in the table below. Month in which student poll was taken Average of students’ responses as MPC March 0.41 June 0.30 September 0.22 December 0.56 What do these MPC’s imply about the students’ thinking over the course of the year?

(40 points) In their 1999 Applied Economics Letters paper, Zakir and Wunnava proposed the following specification in identifying the factors affecting infant mortality rates (IMR): IMR₁ = B₁+ B₁FERTILITY, + ß₂LNGNP; +߸LABOUR; + ßLABOUR² + B₂LITERACY, + BHEALTH; +ε₁ Where i=1,2,..., 117 (i.e., based on a cross-section of 117 countries) IMR = infant mortality rate-number of deaths before age 1 per 1000 live births FERTILITY = number of births per woman LNGNP = the natural logarithm of per capita GNP (note that GNP is measured in '000 of $s) LABOUR = percentage of women in the labor force LITERACY = female literacy rate HEALTH = expenditure on health care as percentage of GNP Following are their estimated regression results along with sample means (based on a cross-section of industrialized and third world countries for 1993).

- 10.61 The per-store daily customer count (i.e., the mean number of customers in a store in one day) for a nationwide convenience store chain that operates nearly 10,000 stores has been steady, at 900, for some time. To increase the customer count, the chain is considering cutting prices for coffee beverages. The question to be determined is how much to cut prices to increase the daily customer count without reducing the gross margin on coffee sales too much. You decide to carry out an experiment in a sample of 24 stores where customer counts have been running almost exactly at the national average of 900. In 6 of the stores, the price of a small coffee will now be $0.59, in 6 stores the price of a small coffee will now be $0.69, in 6 stores, the price of a small coffee will now be $0.79, and in 6 stores, the price of a small coffee will now be $0.89. After four weeks of selling the coffee at the new price, the daily customer count in the stores was recorded and stored in . At the 0.05…arrow_forwardHow would you describe a correlation of -1?

The variable bwght is birth weight, in ounces, faminc is annual family income, in thousands of dollars, cigs is number of cigarettes the mother smoked per day while pregnant, motheduc is mother's education (in years), and fatheduc is father's education (in years): log (bŵght) = 4.73+ 0.146 log( faminc) - (0.03) (0.076) n=1,191 R² = 0.264 0.031 cigs (0.016) (5.1) log (bŵght) = 4.73+ 0.136 log( faminc) - (0.03) (0.076) - 0.051 cigs (0.010) 0.040 motheduc+ 0.041 fatheduc (0.030) n=1,191 R² = 0.286 (0.026) (5.2) (a) In terms of the model parameters, (i) state the null hypothesis that, after controlling for faminc, motheduc, and fatheduc, cigs has no effect on birth weight against the alternative that cigs has a negative effect; and (ii) carry out the test at the 10% significance level (4 points).
