2. Suppose that in the town of Beckertown, black house painters compete against white house painters and they are equally productive. Some employers have a preference for white house painters; they are willing to pay a price so that they do not have to hire black painters. Other employers do not care whether they hire black or white painters as long as they are equally productive. You have been doing research on this market and you know that the...

3. Regressions. You are interested in analyzing whether states with higher banking regulation have higher unemployment rates than states with lower banking regulation. You have the following cross-sectional data on 4 states. unemployment_rate is the state's unemployment rate measured as a percent. regulation_index is a sum of dummy variables that describes the number of banking regulations implemented by the state state unemp rate ulation index 4 a) Estimate the coefficients (BoP1) of the linear model shown below using OLS and...

You want to know whether people who power-pose feel more confident than those who don't. To answer this question, you ask 50 people to power-pose, then rate how confident they are (from 0 to 11) where higher is more. You also ask 50 other randomly picked individuals to rate how confident they are without power-posing. This data is in the file "power_posing.txt". The first column represents the confidence ratings, the second column whether they power-posed (1) or not (0). What...

8. Econometrics (15 pts) Table 2 below shows the impact of a declining fertility rate (births per 100 population) on rates of birth by Cesarean section. The economist estimated a logistic regression model where the dependent variable (Y) equals one for delivery by Cesarean section, 0 for a normal delivery Independent variables in the model include year fixed effects (e), county fixed effects (a), and a vector (X) that controls for mother's age, education, marital status, race and ethnicity, as...

I mainly need help with the second part. Thank you in advance! Starbucks launched its prepaid (debit) Starbucks Card in November 2001. The card, which holds between $5 and $500 can be used at any Starbucks location. Suppose Starbucks management wants to study the reasons why some people purchase debit cards with higher prepaid amounts than do other people. Suppose a study of 25 randomly selected prepaid purchasers is taken. Respondents are asked the amount of the prepaid card, the...

Fuming because you are stuck in traffic? Roadway congestion is a costly item, both in time wasted and fuel wasted. Let x represent the average annual hours per person spent in traffic delays and let y represent the average annual gallons of fuel wasted per person in traffic delays. A random sample of eight cities showed the following data. x (hr) 26 5 20 39 18 23 17 5 y (gal) 46 3 33 54 33 39 29 9 (a)...
