We analyze entry of a firm with a new and differentiated product into a market with two properties: An existing incumbent has a captive consumer base, and all consumers have heterogeneous tastes. The interaction of the share of captive consumers with the degree of taste heterogeneity leads to...

We study the assignment of discrete resources in a general model encompassing a wide range of applied environments, such as school choice, course allocation, and refugee resettlement. We allow single-unit and general multi-unit demands and any linear constraints. We prove the Second Welfare...

We propose a model of competitive attention based on two key premises: i) People have limited information processing capacities and ii) consideration sets are formed according to relative salience. The equilibrium predictions we obtain can help to understand, and connect, diverse empirical...

Using a firm-bank panel of more than 1m German firms over 2010-2016, we document that local public bank lending to municipalities crowds out private investment. Our results show how crowding-out can happen in a developed economy characterized by low interest rates and fiscal austerity. Our...

We conduct a large scale randomized field experiment to study whether providing recipients – 42,454 Chinese households in a rural area – with information on the costs of a real decision they make can help to improve the quality of their choices. The decisions are of high financial impact, as...

Estimates of the effect of fetal health shocks may suffer from survivorship bias. The fetal origins literature seemingly agrees that survivorship bias is innocuous in the sense that it induces a bias toward zero. Arguably, however, selective mortality can imply a bias away from zero. In the case...

Major central banks remunerate reserves at negative interest rates and it is increasingly likely that they will keep rates negative for many more years. To study the long run implications of negative rates, we construct a dynamic general equilibrium model with commercial banks funding investment...

Preferences over risky alternatives can be elicited by different methods, including direct pairwise choices and willingness-to-accept valuations. The results are frequently at odds, casting doubts on the foundations of economics. We develop a stochastic choice model predicting when...

How do parents plan to and effectively share resources with their children over time? In a lab-in-the-field experiment in Malawi, we show that, for many parents, plans become more generous the further in the future consumption is. These parents are, however, way more likely to reverse past...

Teacher absenteeism and shirking are common problems in developing countries. While monitoring teachers should ameliorate those problems, mobilizing parents to do so often leads to small or even negative effects on learning outcomes. This paper provides causal evidence that this might result...
