<p>Even though the Wharton degree is called a B.S. in Economics, that’s for historical reasons (going back over 100 years), and to distinguish it from the usual BBA. You can’t really major in Economics in Wharton–only in CAS. The Wharton program is a more practically focussed business program (finance, accounting, management, marketing, etc.) with a large liberal arts component (up to almost 50%), whereas CAS offers a pure liberal-arts curriculum.</p>
<p>And anyone in CAS can take Wharton courses. Penn encourages such flexibility in all 4 of its undergrad schools through its vaunted “One University” policy, so that undergrads can take courses in the 3 other undergad schools AND in most of the grad and professional schools (Law School, Annenberg School for Communications, School of Design, School of Social Policy and Practice, Graduate School of Education, etc.).</p>
<p>In terms of job placement prospects between CAS and Wharton, you can look through the last 5 or 6 years worth of career surveys for CAS here:</p>

<p>Many of the firms that come to Penn to recruit in the fields you mentioned, do so because of the presence of Wharton, but CAS students are not barred from also interviewing with those firms, and many of them do. However, it is the strength and preeminence of Wharton that attracts the most selective firms in those fields. Nevertheless, as you’ll see in the CAS career surveys, CAS economics majors also do fairly well in getting jobs in those fields.</p>
