Three Essays in Microeconometrics
2020
This dissertation examines three distinct issues using microeconometric techniques. The first two chapters fall in the realm of discrete choice models and try to make allowance for limited attention. The third chapter focuses on firm behavior and investigates the impact of ownership concentration on productivity. Chapter 1 predominantly builds on the consideration capacity model in Dardanoni, Manzini, Mariotti and Tyson (2019). In the attempt to behavioralize rational choice theory, their model identifies the distribution of cognitive characteristics in a population of agents who are observed choosing repeatedly from a single menu. By exploiting algebraic arguments, we first generalize the …
Speed-accuracy trade-off and its consequences in a scramble competition context.
2014
Abstract: Animals foraging in groups commonly respond to the presence of others by increasing their foraging rate, an increase that could come at the expense of prey detection accuracy. Yet the existence and consequences of such so-called 'speed-accuracy trade-offs' in group-foraging animals remain unexplored. We used group-feeding zebra finches, Taeniopygia guttata, to determine how search speed affects food detection accuracy and how a potential speed-accuracy trade-off influences feeding success. We found significant between-individual differences in hopping speed as well as evidence that faster individuals were more likely to overlook food, demonstrating the existence of a trade-off bet…
