Research Interests

If I would have tried to put my research interests in two words, they would be HETEROGENEOUS AGENTS. Empirical evidence and theoretical arguments are mounting against the main actor of the mainstream neoclassical economics: the representative agent!

Starting from the studying the pricing decisions of heterogeneous producers as my master thesis topic at Central European University, I went to study the decisions of heterogeneous consumers and their effects on market dynamics as my PhD research topic at Maastricht University.

Besides mere heterogeneity, consumers have many other interesting features (e.g. interdependence, changes in tastes and other evolutionary properties) which are becoming central to my PhD thesis.

My PhD thesis ("Five Essays on Economies with Heterogenous Interacting Consumers") consists of two parts. One is concerned with the behavior of R&D performing firms with heterogenous sets of information. There I analyze the process of horizontal innovation on firm growth and ultimate firm size distributions, as well as the effects of consumer interaction on innovation incentives. The other part models consumer choice process in multi-product environments. Here I model heterogenous consumers learning from own consumption experience and from interaction with other consumers through social networks. The thesis in total contributes to the understanding of the effects of consumer heterogeneity, interaction and learning processes on the organization of various economic activities (i.e. innovation, advertising, consumption).
