<p>I'm trying to get a measure of market power in the US. Here's what I'd be interested in, ranked from best (what I'm really after) to worst (stuff that kind of hints at my measure, but isn't really it. </p>

<ul>
<li>Price distributions of similar goods in the US, by county/state</li>
<li>Average markups for different goods, by county/state</li>
<li>Average [other characteristic that correlates with higher firm market power], by county/state</li>
</ul>

<p>Importantly, I'm after price distributions of goods <em>consumed</em> in state A, not produced in state A.</p>

<p>I guess I could use the Nielson data set to get some proxy of price distributions, but I don't think that's the strength of the data set. What else is there?</p>

# Market Power and Prices in the US

(Asked by: username_0 on 2015-10-05)

I'm trying to get a measure of market power in the US. Here's what I'd be interested in, ranked from best (what I'm really after) to worst (stuff that kind of hints at my measure, but isn't really it.

* Price distributions of similar goods in the US, by county/state
* Average markups for different goods, by county/state
* Average [other characteristic that correlates with higher firm market power], by county/state

Importantly, I'm after price distributions of goods *consumed* in state A, not produced in state A.

I guess I could use the Nielson data set to get some proxy of price distributions, but I don't think that's the strength of the data set. What else is there?
