On the 2026–27 academic job market

I am a financial economist at the University of Mannheim, where I work at the Chair of Corporate Finance. My research is in corporate finance. I study how firms acquire, reallocate and produce intangible capital: technology and human capital.

I received my PhD (Dr. rer. pol.) in Finance from the University of Mannheim in 2026, advised by Ernst Maug and Oliver Spalt.

An acquirer’s decision to undertake an acquisition, together with its choice of target, can systematically reveal its technological gap. The underlying selection mechanism allows the market to distinguish technological laggards from leaders and update valuations accordingly. I measure this revealed gap as the technological overlap between the target and the acquirer’s industry. Acquirers with larger revealed gaps experience more negative announcement returns, but only when the target is more transparent than the acquirer and thus conveys information beyond the market’s prior beliefs. This effect is concentrated in the component of target choice unexplained by acquisition determinants identified in prior studies. Moreover, revealed gaps induce opposite market reactions among the acquirer’s industry peers. Additional tests help rule out alternative explanations. Taken together, these findings highlight a selection-based mechanism that helps explain the cross-section of acquirer announcement returns.

Arbitraging Labor Markets

With Ernst Maug and Christoph Schneider. ECGI Working Paper in Finance No. 997. SSRN

Abstract

We develop a new rationale for firms to operate in multiple locations within the same country. We show that business group firms relocate operations and grow less if firms of the same group in other local labor markets offer a better labor supply, an improved fit between the requirements of the firm and the local labor force, and lower labor costs. The first two aspects are more important than costs; hence, business groups primarily address their access to human capital. Relocation is concentrated in industries with lower asset tangibility, in high-skilled jobs, and in business groups with decentralized managerial functions. Local labor conditions are of similar importance to and distinct from agglomeration economies. Business groups predominantly move jobs, but not employees, between their locations. As such, they arbitrage local labor markets.

Tolerance for Failure: Evidence from Patent Examination

With Bastian Koch.

Abstract

We introduce a novel firm-level measure of failure tolerance based on firms’ patenting histories. Specifically, we quantify failure tolerance as the largest scope loss during patent examination that does not terminate a firm’s innovation sequence. Firms with greater failure tolerance tend to produce patents that are more valuable, more cited, more complex, yet also more likely to fail. At the same time, they file fewer patents and employ fewer inventors, resulting in an ambiguous relationship between failure tolerance and total innovation output. Exploiting inventor job switches, we provide causal evidence that higher failure tolerance enhances inventor productivity.
