PictureI'm currently working as a Lecturer in the Cardiff Business School. 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 speciality is in applied micro theory. If you have a research idea, write me, I try to reply all emails I get.

Leadership in Scholarship: A Machine Learning Based Investigation of Editors' Influence on Textual Structure


With Ali Sina Önder and Sascha Schweitzer. Full text, AER topic loadings in time, words in topics.

Academic journals disseminate new knowledge, and editors of prominent journals are in a position to affect the direction and composition of research. Using machine learning procedures, we measure the influence of editors of the American Economic Review (AER) on the relative topic structure of papers published in the AER and other top general interest journals. We apply the topic analysis apparatus to the corpus of all publications in the Top 5 journals in Economics between 1976 and 2013, and also to the publications of the AER's editors during the same period. This enables us to observe the changes occurring over time in the relative frequency of topics covered by the AER and other leading general interest journals over time. We .nd that the assignment of a new editor tends to coincide with a change of topics in the AER in favour of a new editor's topics which can not be explained away by shifts in overall research trends that may be observed in other leading general interest journals.

Same Sex Marriage, The Great Equalizer

With Aleksey Parakhonyak.

We demonstrate the abundance of asymmetric equilibria in a standard marriage market model, when agents must only engage in heterosexual marriage: agents of different gender are not guaranteed to have the same payoff even under equal opportunities, even if all other factors, such as own type or the distribution of partner types, are same across genders. Then we allow for same-sex marriage, and we demonstrate that under equal opportunities, when genders are symmetrical, only symmetric equilibria survive. Presented at:

Alma Mat(t)er(s): Determinants of Early Career Success in Economics


With Sascha Baghestanian. Full text, currently under rewriting.

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.

On Basu's Proposal: Fines Affect Bribes


Full text.

I provide a model that connects the bribe amount with the fines imposed on both bribe-taker and bribe-payer. I show that Basu (2011) proposal to not punish bribe-payers to induce whistleblowing does not have to help lower bribes. Higher fines on bribe-takers will make them ask for larger bribes, whereas lowering fines for bribe-paying on bribe-payers might increase their willingness to pay the bribe. An increase in transparency, if achieved, effectively increases both fines simultaneously. Presented at:
