Welcome! I am a Researcher at the Luxembourg Institute of Socio-Economic Research (LISER).
I work on Microeconomics. My research brings theories of individual and household demand and labour supply to the data, by using revealed preference methods. I am also the principal investigator of <Timing: theoretical, empirical and experimental investigation of household time choices> (Luxembourg National Research Fund) jointly with Alexandros Theloudis.

Togetherness in the Household (with Alexandros Theloudis and Bertrand Verheyden)
Winner of the 2019 Prize in memory of Maria Concetta Chiuri, awarded by the Società Italiana di Economia Pubblica.
Spending time together with a spouse is a major gain from marriage. We extend the classical collective model of the household to allow for togetherness between spouses. Togetherness takes the form of joint leisure and joint care for children. Using revealed preferences conditions and Dutch data over years 2009-12, we find that households are willing to pay 1.2 euros per hour -10% of the average wage- to convert private leisure to joint, and 2.1 euros per hour to convert private childcare to joint. Our results suggest togetherness is an important component of household time use despite being overlooked in the economics literature.
