Optimal Long-Term Contracting with Learning
We introduce uncertainty into Holmstrom and Milgrom (1987) to study optimal long-term contracting with learning. In a dynamic relationship, the agent's shirking not only reduces current performance but also increases the agent's information rent due to the persistent belief manipulation effect. We characterize the optimal contract using the dynamic programming technique in which information rent is the unique state variable. In the optimal contract, the optimal effort is front-loaded and decreases stochastically over time. Furthermore, the optimal contract exhibits an option-like feature in ...

Dealers and the Dealer of Last Resort: Evidence from the Agency MBS Markets in the COVID-19 Crisis
When market disruptions started in March 2020, dealers maintained the usual liquidity provision in the agency MBS market by taking cash inventory and hedging inventory risk with forward contracts. However, cash and forward prices significantly diverged and began to converge only after the Federal Reserve deployed nonstandard purchase operations to promptly take MBS off dealers’ balance sheets. Further cross-dealer analyses point to supplemental leverage ratio requirements as major constraints on dealers’ balance sheets. Customers’ selling increased when price divergence reverted, ...

The Role of Information in Pharmaceutical Advertising: Theory and Evidence
This paper theoretically and empirically examines the role of information in the practice of pharmaceutical detailing (promotional interactions between drug representatives and physicians). We start with a theoretical framework in which pharmaceutical firms target detailing visits to physicians who potentially learn about drug quality and prescribe it to their patients. We derive several predictions about the role of information in these visits, which we then test empirically using Medicare Part D prescriptions and pharmaceutical detailing visit data. We find there is little empirical ...

Attention and Fluctuations in Macroeconomic Uncertainty
This paper studies a dispersed information economy in which agents can exert costly attention to learn about an unknown aggregate state of the economy. Under certain conditions, attention and four measures of uncertainty are countercyclical: Agents pay more attention when they expect the economy to be in a bad state, and their reaction generates higher (i) aggregate output volatility, (ii) cross-sectional output dispersion, (iii) forecast dispersion about aggregate output, and (iv) subjective uncertainty about aggregate output faced by each agent. All these phenomena are prominent features of ...

Can subjective expectations data be used in choice models? Evidence on cognitive biases
A pervasive concern with the use of subjective data in choice models is that the data are biased and endogenous. This paper examines the extent to which cognitive biases plague subjective data, specifically addressing 1) whether cognitive dissonance affects the reporting of beliefs, and 2) whether individuals exert sufficient mental effort when probed about their subjective beliefs. For this purpose, I collect a unique panel data set of Northwestern University undergraduates that contains their subjective expectations about outcomes specific to different majors in their choice set. I do not ...

How Much Is Priced In? Market Expectations for FOMC Rate Hikes from Different Angles
It is essential for policymakers and financial market participants to understand market expectations for the path of future policy rates because these expectations can have important implications for financial markets and the broader economy. In this post?which is meant to complement prior Liberty Street Economics posts, including Crump et al. (2014a, 2014b ) and Brodsky et al. (2016a, 2016b)?we offer some insights into estimating and interpreting market expectations for increases in the federal funds target range at upcoming meetings of the Federal Open Market Committee (FOMC).

Disagreement and learning in a dynamic contracting model
We present a dynamic contracting model in which the principal and the agent disagree about the resolution of uncertainty, and we illustrate the contract design in an application with Bayesian learning. The disagreement creates gains from trade that the principal realizes by transferring payment to states that the agent considers relatively more likely, a shift that changes incentives. In our dynamic setting, the interaction between incentive provision and learning creates an intertemporal source of ?disagreement risk? that alters optimal risk sharing. An endogenous regime shift between ...

Can Reputation Ensure Efficiency in the Structured Finance Market? Majority Voting: A Quantitative Investigation
In Elamin (2013), the credit rating agency (CRA) cannot credibly fully reveal its information about the quality of a rated structured finance project, when ratings are unverifiable. Can the fear of losing its reputation discipline the CRA? In this paper, there is incomplete information about the type of the CRA. With some probability, it can be a truthful type, always fully revealing its information. At every period, the (updated) probability that the CRA is of the truthful type is its reputation. With only two project types and when the CRA?s reputation is high enough, an informationally ...

Overconfidence, Subjective Perception, and Pricing Behavior
We study the implications of overconfidence for price setting in a monopolistic competition setup with incomplete information. Our price-setters overestimate their abilities to infer aggregate shocks from private signals. The fraction of uninformed firms is endogenous; firms can obtain information by paying a fixed cost. We find two results: (1) overconfident firms are less inclined to acquire information, and (2) prices might exhibit excess volatility driven by nonfundamental noise. We explore the empirical predictions of our model for idiosyncratic price volatility.

The Effect of Safe Assets on Financial Fragility in a Bank-Run Model
Risk-averse investors induce competitive intermediaries to hold safe assets, thereby lowering the probability of a run and reducing financial fragility. We revisit Goldstein and Pauzner (2005), who obtain a unique equilibrium in the banking model of Diamond and Dybvig (1983) by introducing risky investment and noisy private signals. We show that, in the optimal demand-deposit contract subject to sequential service, banks hold safe assets to insure investors against investment risk. Consequently, fewer investors withdraw prematurely, which reduces the probability of a bank run. Safe asset ...
