Selected Research

Gender effects in risk taking have attracted much attention by economists, and remain debated. Loss aversion — the stylized finding that a given loss carries substantially greater weight for decisions than a monetarily equivalent gain — is a fundamental driver of risk aversion. We deploy four definitions of loss aversion commonly used in the literature to investigate gender effects. Even though the definitions only differ in subtle ways, we find women to be more loss averse than men according to one definition, while another definition results in no gender differences, and the remaining two definitions point to women being less loss averse than men. Conceptually, these contradictory effects can be organized by systematic measurement error resulting from model mis-specifications relative to the true underlying decision process.
Working Paper (Submitted), 2018

Increased competition for viewers’ time is threatening the viability of public-service broadcasters (PSBs) around the world. Changing regulations regarding advertising minutes might increase revenues, but little is known about the structure of advertising demand. To address this problem, we collect a unique dataset on monthly impacts (quantities) and prices of UK television channels between 2002 and 2009 to estimate the (inverse) demand for advertising on both public and commercial broadcasters. We find that increasing PSB advertising minutes to the level permitted for non-PSBs would increase PSB and industry revenue by 10.5% and 6.7%.

Installation Guide for Software and Packages

While teaching programming skills I have assembled a set of instructions for setting up a computing environment that I find useful for economics / marketing research. Instructions are provided for Linux (Ubuntu flavored), Mac and Windows environments.

  • Installation Guide
    • Borrowed and updated from the programming course I co-taught at UZH in 2017.

Reproducible Research Workflows

The Snakemake workflow management system helps to create reproducible and scalable data analyses. It was originally designed for Bioinformatics workflows, but I have found it suits research in empirical economics and marketing just as well. Official documentation for Snakemake is here. Below are some templates that I use for my research and an extended tutorial.

Some of my older projects use Waf to implement a reproducible workflow. Waf was introduced to me by Hans-Martin von Gaudecker. He provides great templates here in multiple programming languages along with an extended tutorial. It’s a good alternative, but I think the Waf learning curve is a tad steeper.

Markdown templates

Most of my written work is in markdown. Here are some templates I regularly use:
