In RD designs with multiple cutoffs, the identification of an average causal effect across cutoffs may be problematic if a marginally exposed subject is located exactly at each cutoff. This occurs whenever a fixed number of treatment slots is allocated starting from the subject with the highest...

We investigate empirically how sellers react to changes in the population of their consumers, identifying the effects of demand composition and demand size with limited information on costs. We show how pharmacists in Italy selectively increase the price of some products when they observe in...

University tuition typically remains constant throughout the years of enrollment while delayed degree completion is increasingly a problem for academic institutions around the world. Theory suggests that if continuation tuition were raised, the probability of late graduation would be reduced....

For many students throughout the world the time to obtain an academic degree extends beyond the normal completion time while college tuition is typically constant during the years of enrollment. In particular, it does not increase when a student remains in a program beyond the normal completion...

We study an inflow of buyers who are less elastic because they lack both time and information. Theory predicts that sellers increase prices to expand surplus appropriation, even if marginal costs are non-increasing, but this effect weakens as market competition intensifies. Data from Italian...

We study the entrance in a retail market of consumers who are less elastic because of hurriedness and lack of information. Theory predicts that firms react by increasing prices to expand surplus extraction, but this effect weakens as market competition increases. High frequency data from Italian...
