I'm currently working as a Lecturer in the Queen's University Management School in Belfast, Northern Ireland. I am working mostly in the fields of applied micro and econometrics, I invent models, quantify their predictions and test their consistency with the data.
Research supervision: I am eager to supervise PhD students in many topics (from international trade to social choice to corruption to mechanism design), but my specialty is in applied micro theory. If you have a research idea, write me, I try to reply all emails I get.

We present a model for academia with heterogeneous author types and endogenous effort to evaluate recent changes in the publication process in Economics. We analyze the implications of these developments on research output. Lowering the precision of refereeing signals lowers the effort choices of intermediate ability authors, but invites more submissions from less able authors. Increasing the number of journals stimulates less able authors to submit their papers. The editor can improve the journal’s quality pool of submitted manuscripts by improving the precision of refereeing, but not by lowering acceptance standards. The submission strategy of an author is informative of his ability. Presented at:
We study 6000 author-publication observations to investigate predictors of early career success in six fields of Economics. Concentrating on top researchers enables us to control for the effects of ability and effort, and focusing on the start of their careers minimizes distortions from reputation feedback. Our results reveal that the most important predictor for early career success is the ranking of an author’s PhD granting institution, followed by his first placement. Our insights suggest that a counterfactual decrease in the Alma Mater of a high ability author, who graduated from a top 10 university, by as little as 10 to 20 ranks, reduces his probability of getting a top 5 publication significantly by 13 percentage points. Lowering the ranking of his Alma mater by another 80 ranks decreases his chances of getting a top publication by a factor of three. Our findings suggest that the Economics publication market values Alma mater signals, discounting newcomers graduating from- or working at lower ranked departments.
We study how ownership structure and management objectives interact in determining the company size without assuming informational shortcomings or explicit costs of management. For a general class of payoff functions, we characterize the optimal company size. To accomplish that, we show how the general effort aggregation function can be boiled down to the teamwork efficiency function. The shape of the teamwork efficiency function turns to be the key determinant of the optimal effort choice under various institutional settings, which in turn provides insights for the optimal size of the firm. We demonstrate the restrictiveness of the common assumptions on effort aggregation (i.e., constant elasticity of effort substitution), and we show that common intuition (i.e., that corporate companies are more efficient and therefore will be larger in size than equal-share partnerships) might not hold in general.
