<p>I am curious about the use of the <a href="https://stats.stackexchange.com/questions/tagged/econometrics" class="post-tag" title="show questions tagged &#39;econometrics&#39;" rel="tag">econometrics</a> tag. Its Wiki says </p>

<blockquote>
  <p>a field of statistics dealing with applications to economics.</p>
</blockquote>

<p>This makes some sense, but I tend to think of the distinction between econometrics and the rest of statistics more in terms of <em>models and techniques</em> (such as structural models based on economic theory and instrumental variables estimation) rather than just the <em>applications</em>. Because on one hand one can do a "purely statistical" modelling of an applied economics problem, but on the other hand one can do something "typically econometric" (distinct from a typical statistical application). </p>

<p>I would rather have an <code>economics</code> tag for application in economics. Now we do have <a href="https://stats.stackexchange.com/questions/tagged/macroeconomics" class="post-tag" title="show questions tagged &#39;macroeconomics&#39;" rel="tag">macroeconomics</a> and <a href="https://stats.stackexchange.com/questions/tagged/finance" class="post-tag" title="show questions tagged &#39;finance&#39;" rel="tag">finance</a> tags for questions that have macroeconomics or finance as their applications. (Macroeconomics is clearly a subfield of economics, and finance can also be considered a subfield of economics, although this is less clear cut; so probably an <code>economics</code> tag would be too broad, I am not sure.) And that is just fine, it helps people interested in macroeconomic or financial applications track the relevant questions. Meanwhile, I would see a different role for the <a href="https://stats.stackexchange.com/questions/tagged/econometrics" class="post-tag" title="show questions tagged &#39;econometrics&#39;" rel="tag">econometrics</a> tag based on what I articulated above.</p>

<p>Any opinions?</p>
