			<content:encoded><![CDATA[<p>The <a href="http://www.aeaweb.org/joe/listings.php">AEA&#8217;s JOE postings</a> present the near-population of jobs available for newly-minted economic PhDs.  I used the XML data available for download to create a mash-up of job locations on Google Maps.  I break the posting down into <a href="http://michaelewens.com/joe_map.html">US full-time academic</a>, <a href="http://michaelewens.com/non-us-academic.html">international full-time academic</a> and <a href="http://michaelewens.com/non-academic.html">non-academic</a>.  Here is how I create the maps: <a href="http://michaelewens.com/joe_map.html"><img class="alignleft size-medium wp-image-577" title="Screen shot 2009-10-31 at 9.05.55 PM" src="http://michaelewens.com/wp-content/uploads/2009/10/Screen-shot-2009-10-31-at-9.05.55-PM-300x186.png" alt="Screen shot 2009-10-31 at 9.05.55 PM" width="300" height="186" /></a></p>
<ol>
<li>Select the<a href="http://www.aeaweb.org/joe/listings.php"> subset of the data</a> you want (e.g. US academic) and download the XML file.</li>
<li>Fix some validation errors: take out the &#8220;&lt;&#8221; and &#8220;&gt;&#8221; within the text of nodes (I use <a href="http://macromates.com/">TextMate</a> for this).</li>
<li>Parse the XML file with a custom PHP script that creates a csv file with school, position, location and url to posting. <a href="http://michaelewens.com/parse_joe.phps">Here is my simple script</a> for the academic XML file.</li>
<li>Save the csv file produced by the script in step 3 as an Excel spreadsheet (Google Docs doesn&#8217;t like csv&#8217;s).  Add a &#8220;Latitude&#8221; and &#8220;Longitude&#8221; column to the spreadsheet.</li>
<li>Upload the Excel file to Google docs.</li>
<li><a href="http://otherfancystuff.blogspot.com/2008/11/geocoding-with-google-spreadsheets-and.html">Follow these directions</a> to populate the latitude and longitude of each position+location.</li>
<li>Publish the Google spreadsheet and save the unique id in the url that Google gives you.</li>
<li><a href="http://code.google.com/apis/maps/signup.html">Sign up for a Google Maps API account.</a></li>
<li><a href="http://gmaps-samples.googlecode.com/svn/trunk/spreadsheetsmapwizard/makecustommap.htm">Follow these directions</a> to produce a Google map of your postings.</li>
</ol>
<p>UPDATE: <a href="http://www.batchgeocode.com/">This service</a> may make this process a bit easier, produce cleaner maps and allow the incorporation of more information.</p>
<p>Maybe the AEA can follow these directions to produce these maps after this year.  <a href="http://michaelewens.com/contact/">Contact me</a> with any suggestions or questions.</p>

			<content:encoded><![CDATA[<p>From the<a href="http://www.indeed.com/"> Indeed job listing aggregation site</a>, one can look at trends in both supply (employers) and demand (potential employees).  The demand-side is slightly tricky to interpret because it is a function of not only real employment demand, but the popularity of Indeed as a search platform.  Here are some interesting facts:</p>
<p><strong>Finance: <a href="http://www.indeed.com/jobtrends/financial-services-and-banking-industry">Supply of jobs falls, demand increases</a></strong></p>
<blockquote><p>Financial Services and Banking job postings have decreased 39% since March 2008.</p>
<p>Clicks on Financial Services and Banking jobs have increased 96% since March 2008.</p></blockquote>
<p><strong>Construction employment falls</strong></p>

<p><a href="http://www.simplyhired.com/a/jobtrends">SimplyHired.com</a> also has a trends section with similar patterns.</p>
