Maintaining efficiency while integrating entrants from lower performing groups: an experimental study
Efficiently growing a group often requires integrating individuals from lower performing entities. We explore the effectiveness of policies intended to facilitate such integration, using an experiment that models production as a coordination game. We create an efficient group and an inefficient one. We then allow individuals to move into the efficient group under different mechanisms…

Dopamine modulates the functional organization of the orbitofrontal cortex
Neuromodulators such as dopamine can alter the intrinsic firing properties of neurons, and may thereby change the configuration of larger functional circuits. The primate orbitofrontal cortex (OFC) receives dopaminergic input from midbrain nuclei, but the role of dopamine in the OFC is still unclear. Here we tested the idea that dopaminergic activity changes the pattern of…

Network formation with local complements and global substitutes: the case of R&D networks
In this paper we introduce a stochastic network formation model where agents choose both actions and links. Neighbors in the network benefit from each other’s action levels through local complementarities and there exists a global interaction effect reflecting a strategic substitutability in actions. The tractability of the model allows us to provide a complete equilibrium…

The taxation of superstars
How are optimal taxes affected by superstar phenomena? To answer this question, we extend the Mirrlees model to incorporate an assignment problem in the labor market that generates superstar effects. Perhaps surprisingly, rather than providing a rationale for higher taxes, we show that superstar effects provide a force for lower marginal taxes conditional on the observed distribution…

The lasting legacy of seasonal influenza: in-utero exposure and labor market outcomes
Pregnancy conditions have been shown to matter for later economic success, but many threats to fetal development that have been identified are difficult to prevent. In this paper I study seasonal influenza, a preventable illness that comes around every year and causes strong inflammatory responses in pregnant women. Using administrative data from Denmark, I identify the effects of…

When work disappears: manufacturing decline and the falling marriage-market value of men
The structure of marriage and child-rearing in U.S. households has undergone two marked shifts in the last three decades: a steep decline in the prevalence of marriage among young adults, and a sharp rise in the fraction of children born to unmarried mothers or living in single-headed households. A potential contributor to both phenomena is the declining labor-market opportunities…

High-skilled immigration, STEM employment, and non-routine-biased technical change
We study the role of foreign-born workers in the growth of employment in STEM occupations since 1980. Given the importance of employment in these fields for research and innovation, we consider their role in a model featuring endogenous non-routine-biased technical change. We use this model to quantify the impact of high-skilled immigration, and the increasing tendency of such…

Nonlinear effects of taxation on growth
We propose a model consistent with two observations. First, the tax rates adopted by different countries are generally uncorrelated with their growth performance. Second, countries that drastically reduce private incentives to invest severely hurt their growth performance. In our model, the effects of taxation on growth are highly nonlinear. Low tax rates have a very small impact on…

Revealed preferences in a sequential prisoners' dilemma: a horse-race between five utility functions
We experimentally investigate behavior and beliefs in a sequential prisoner’s dilemma. Each subject had to choose an action as first-mover and a conditional action as second-mover. All subjects also had to state their beliefs about others’ second-mover choices. We find that subjects’ beliefs about others’ choices are fairly accurate on average. Using the elicited beliefs, we compare…

Herding: a new phenomenon affecting medical decision-making in multiple sclerosis care? Lessons learned from DIScUTIR MS
Purpose: Herding is a phenomenon by which individuals follow the behavior of others rather than deciding independently on the basis of their own private information. A herding-like phenomenon can occur in multiple sclerosis (MS) when a neurologist follows a therapeutic recommendation by a colleague even though it is not supported by best practice clinical guidelines. Limited…

Deficits in reinforcement learning but no link to apathy in patients with schizophrenia
Negative symptoms in schizophrenia have been linked to selective reinforcement learning deficits in the context of gains combined with intact loss-avoidance learning. Fundamental mechanisms of reinforcement learning and choice are prediction error signaling and the precise representation of reward value for future decisions. It is unclear which of these mechanisms contribute to the…

Pre-play communication with forgone costly messages: experimental evidence on forward induction
We experimentally study optional costly communication in Stag-Hunt games. Prior research demonstrates that efficient coordination is difficult without a communication option but obtains regularly with mandatory costless pre-play messages. We find that even small communication costs dramatically reduce message use when communication is optional, but efficient coordination can occur…

Nonlinear shrinkage of the covariance matrix for portfolio Selection: Markowitz Meets Goldilocks
Markowitz (1952) portfolio selection requires an estimator of the covariance matrix of returns. To address this problem, we promote a nonlinear shrinkage estimator that is more flexible than previous linear shrinkage estimators and has just the right number of free parameters (i.e., the Goldilocks principle). This number is the same as the number of assets. Our nonlinear shrinkage…
