			<content:encoded><![CDATA[<p>Appena letto <a href="http://www.ilfattoquotidiano.it/2011/10/11/thomas-sargent-nobel-atipico/163064/trackback/">questo post</a>:</p>
<blockquote><p>Sargent, con Lucas e tutta la loro scuola, è assolutamente contrario all’uso di modelli macroeconomici sia per la previsione, sia soprattutto per individuare gli strumenti e le misure di politica economica. I parametri stimati sul passato non aiutano a capire il futuro e l’econometria non dovrebbe essere usata in modo improprio per giustificare esperimenti di ingegneria sociale.</p></blockquote>
<p>E non può non tornarti in mente un <a href="http://teaching.fec.anu.edu.au/ECON8022/2009/Readings/Lucas1980.pdf">vecchio articolo del 1980</a> di Bob Lucas, in cui descrive il proprio approccio metodologico allo studio della (macro)economia:</p>
<blockquote><p>Our task as I see it (&#8230;) is to write a FORTRAN program that will accept specific economic policy rules as &#8220;input&#8221; and will generate as &#8220;output&#8221; statistics describing the operating characteristics of time series we care about, which are predicted to result from these policies. For example, one would like to know what average rate of unemployment would have prevailed since World War II in the United States had M1 grown at 4 percent per year during this period, other policies being as they were.</p></blockquote>
<p><span style="text-decoration:underline;">Update:</span> al momento, il link al post originario non funziona più (non c&#8217;è più traccia di quell&#8217;articolo <a href="http://www.ilfattoquotidiano.it/blog/fscacciavillani/">sul blog d&#8217;origine</a>), forse per via dei problemi avuti in questi giorni <a href="http://www.corriere.it/cronache/11_ottobre_12/gomez-fattoquotidiano_2cb0bc92-f4ed-11e0-a9a5-9e683f522ea7.shtml">dal sito del Fatto Quotidiano</a>. Comunque sia, ringraziate il duo Page-Brin per aver inventato la <a href="http://webcache.googleusercontent.com/search?q=cache:5BCldWMNfLEJ:www.ilfattoquotidiano.it/2011/10/11/thomas-sargent-nobel-atipico/163064">cache di Google</a>.</p>
<p><span style="text-decoration:underline;">Update II:</span> il post è di nuovo online, a <a href="http://www.ilfattoquotidiano.it/2011/10/16/thomas-sargent-nobel-atipico/163304/">questo nuovo link</a>.</p>
