Earlier in her career, Buch worked as professor at the University of Tübingen[1] and served as a member of the German Council of Economic Experts.
[5] In 2004 Buch was appointed professor at the University of Tübingen, holding the chair for International Macroeconomics and Finance with a focus on money and currency.
[3] Between July and December 2010, Buch served as member of the Expert Council for Exit Strategies in the Financial Sector at the German Federal Ministry of Finance.
[8] In a 2012 interview with Frankfurter Allgemeine Zeitung, Buch held that “Eurobonds in the framework of a political union, with joint control and a surrendering of fiscal powers, would be theoretically an alternative in the long term.” While calling such as solution “politically unrealistic,” she promoted the debt-redemption fund as an alternative to European Central Bank monetization of sovereign debt.
The fund, which would mutualize euro-area debt exceeding 60 percent of member states’ economic output in return for strict conditions, would offer a temporary solution until the bloc stabilize its finances, Buch told the newspaper.
"[10] In 2013, Buch and Elke König, who headed the Federal Financial Supervisory Authority (BaFin) at the time, were cited by German media as contenders for a post on the Executive Board of the European Central Bank that eventually went to Sabine Lautenschläger.
[11] Between July 2013 and March 2014, Buch served as member of the European Commission’s expert group on debt redemption fund and eurobills, led by Gertrude Tumpel-Gugerell.
[citation needed] At the time, German news media like Der Spiegel considered Buch's nomination a victory for Finance Minister Wolfgang Schäuble and Chancellor Angela Merkel’s Christian Democratic-led bloc in a power struggle with their Social Democratic coalition partners; Vice Chancellor Sigmar Gabriel, led the SPD at the time, reportedly wanted to give the job to Bundesbank board member Joachim Nagel.
