Interpret the coefficient on logged real gasoline price (lnP) in terms of the sign, magnitude and statistical significance. What does this estimate tell us about the average response of gasoline demand to changes in prices from 1975-1980.
[lnGas = ln(gascap)
lnP = ln(realprice)
lnInc = ln(inccap)
realprice = Real price of gasoline (2000 $)
gascap = Gas demanded per capita (gallons per month)
inccap = Real income per capita (2000 $)
date = Year and month of observation (text)
year = Year of observation
month = Month of observation]
As both independent and dependent variables are in log form, the coefficient could be interpreted in elasticity term.
In this case, as real price of gasoline increases by 1%, the demand of the gasoline will increase by 1%. (The answer is based on the regression output shown in the question.)
As per the model, income elasticity of demand of gasoline is less than 1.
P.S. I doubt the validity of the regression result posted in the question. Methodology used to analyse the data may not be right. However, I am submitting my answer considering the output is correct.

The coefficients for the month of observation,
_Imonth_2, _Imonth3, etc. are mean effects (dummy variables) that
shift the intercept of our demand equation for each month of the
sample. In terms of what we know about gasoline demand, why might
it be important to model different baseline gasoline consumption by
month?

Estimate from 1975-1980:
Estimate from 2001 – 2006:
a. Compare the estimated price elasticity during these
years with your estimate from 1975-1980 above.
b. Interpret the estimated coefficient on logged per
capita income (lnInc). Discuss the sign, magnitude and statistical
significance. What does this estimate tell us about how gasoline
demand in the 2000’s responded to changes in income?
(Please answer a & b completely) Thank
you!
