Fwd: Question about problem set 3

[Yan, Lin]

Hi guys,

Plz see TA's response below. I think using aggregate is fine, but feel free to share your opinions.

Hi Claire,

You should choose the sample you think is best.

As long as you justify your choice you're fine.

Hi Professor Bursztyn,

 

We have a question regarding the problem set 3. For the regression, do you want us to run a regression for each market areas (which means 6 regressions) or do you want us to just run an aggregate regression for all the market areas? Please kindly advise.

 

Thanks a lot.

 

Best Regards,

If that is the case, I'd prefer to show the aggregate equation in
question 1 then use the market-specific equation for questions 4-7. I
think it's reasonable to assert that demand characteristics and
sensitivities to other factors would vary by market (e.g. it would
take a much larger advertising spend to move the sales needle in NY
than Omaha).

Thoughts?

[Yan, Lin]

Sure, as long as we explain the rationale, we are ok.

I'm here, guys. I'm on it. Just taking a sec to write our
justification, then I'll send around.

OK, after looking back through some of the coefficients for the
market-specific regressions, I think those equations might be a little
crazy. I've stuck to the aggregate equation across the board and
included a justification in question 1 as to our reasoning. Check it
out and let me know when it's safe to send. I'm just reading
accounting tonight, so feel free to reply right up to 11.

I agree with just using the aggregate equation. Looks good, Dustin!

My dad's in town so I'm out and won't have computer access. I trust
your guys' executive decision!

Some of the coefficients seem odd (specifically that advertising expenditures and income coefficients would have so much of an impact), but all of the math seems to check out.  Thanks Dustin.
