5. (26 points) The following two equations were estimated using a sample of births for the year 2010. 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). (b) Controlling for cigs, is faminc individually significant at the 1% level against a two- sided alternative? (4 points)

The next 3 questions refer to the following: A housecleaning company receives 36 for each house cleaned. The tab below gives the relation between the number of workers and the number houses that can be cleaned per week. [[[[ Number of], [Workers]], [[Houses], [Cleaned]]], [0, 0], [1, 9], [2, 17], [3, 24], [4, 30], [5, 35], [6,36]] The marginal revenue from the fourth worker is If the company want to maximize profit and hires three workers, the wa rate of a house - cleaner can be no more than If the wage rate of a house - cleaner is 140, the maximum amount of pr the company can earn is

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?   (Enter response here.)   What is likely happening in the economy during the same period of time?

Hanna, who is a 5-year-old girl, eats nothing but pasta, yogurt, and lemonade. Each month her parents buy 32 pounds of pasta, 79 packages of yogurt, and 22 bottles of lemonade. Hanna's parents have recorded the prices per unit of pasta, yogurt, and lemonade for the last four months, as shown in the table below. Hanna's Meals Month Pasta (dollars per pound) Yogurt (dollars per package) Lemonade (dollars per bottle) January $1.83 $1.14 $2.58 February 1.90 1.04 2.35 March 2.07 0.95 2.54 April 2.26 1.04 2.77 Instructions: Round your answers to two decimal places. a. Compute the total monthly cost of Hanna's meals and indicate whether inflation, deflation (negative inflation), or no inflation occurred during these months. In January, the total monthly cost was $.

2. (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). Mean of IMR: 44.983 Variable name Estimated t-ratio Mean coefficient FERTILITY 10.812 7.848 3.5556 LNGNP -6.998 -3.134 8.2585 LABOUR 4.135 3.359 40.051 LABOUR²…
