Asymmetric firm dynamics under rational inattention
We study the link between business failures, markups and business cycle asymmetry in the U.S. economy with a model of optimal firm exit under rational inattention. We show that the model's predictions of lagged, counter-cyclical and positively skewed markups together with counter-cyclical exit rates are consistent with the empirical evidence. Moreover, our model uncovers a new mechanism that links information processing with the business cycle. It predicts counter-cyclical attention to economic conditions consistent with survey evidence.

Rationally Inattentive Savers and Monetary Policy Changes: A Laboratory Experiment
We present a model where rationally inattentive agents decide how much to save while imperfectly tracking interest rate changes. Suitable assumptions on agents’ preferences and interest rate distribution allow us to derive testable theoretical predictions and their implications for monetary policy. We probe these predictions using a laboratory experiment with induced inattention that closely reflects the theoretical assumptions. We find that, empirically, the laboratory data corroborates the results of the theoretical model. In particular, we show that experimental subjects respond to ...

Rationally Inattentive Consumer: An Experiment
This paper presents a laboratory experiment that directly tests the theoretical predictions of consumption choices under rational inattention. Subjects are asked to select consumption when income is random. They can optimally decide to reduce uncertainty about income by acquiring signals about it. The informativeness of the signals directly relates to the cognitive effort required to process the information. We find that subjects? behavior is largely in line with the predictions of the theory: 1) Subjects optimally make stochastic consumption choices; 2) They respond to incentives and changes ...

Cost of decisionmaking influences individual selections
Market prices are often driven by choices later viewed as mistakes. Waves of optimism or pessimism sometimes dramatically move prices; a burst bubble of euphoria can bring significant macroeconomic consequences. ; A sudden change of sentiment may occur when a large number of stock market professionals consistently err by holding on to stocks for too long when they should sell, or by selling equities too quickly when they should be holding on to them. Yet, these individuals are specialists with every incentive to evaluate stocks correctly. ; Behavioral experiments show that in laboratory ...
Economics of Love: Rejection Worth Chance at Dream Date
With the advance of social networks and increasing prevalence of online dating, the question of how men and women match up has gained importance in economics and society.

'Rational inattention' guides overloaded brains, helps economists understand market behavior
Between Internet news sources, social media and email, people are awash in information, most of it accessible at near-zero cost. Yet, humans possess only a finite capacity to process all of it. The average email user, for example, receives dozens of messages per day. The messages can?t all receive equal attention. How carefully does someone read an email from a sibling or friend before crafting a reply? How closely does a person read an email from the boss?> ; Limitations on the ability to process information force people to make choices regarding the subjects to which they pay more or less ...

Targeted Search in Matching Markets
We propose a parsimonious matching model where a person's choice of whom to meet endogenizes the degree of randomness in matching. The analysis highlights the interaction between a productive motive, driven by the surplus attainable in a match, and a strategic motive, driven by reciprocity of interest of potential matches. We find that the interaction between these two motives differs with preferences?vertical versus horizontal?and that this interaction implies that preferences recovered using our model can look markedly different from those recovered using a model where the degree of ...

The rigidity of choice: Lifecycle savings with information-processing limits
This paper studies the implications of information-processing limits on the consumption and savings behavior of households through time. It presents a dynamic model in which consumers rationally choose the size and scope of the information they want to process concerning their financial possibilities, constrained by a Shannon channel. The model predicts that people with higher degrees of risk aversion rationally choose more information. This happens for precautionary reasons since, with finite processing rate, risk averse consumers prefer to be well informed about their financial ...

Inflation is not always and everywhere a monetary phenomenon
Fiscal policy is as significant as, and sometimes more important than, monetary policy in determining the price level and, therefore, the dynamics of inflation.

A theory of targeted search
We present a theory of targeted search, where people with a finite information processing capacity search for a match. Our theory explicitly accounts for both the quantity and the quality of matches. It delivers a unique equilibrium that resides in between the random matching and the directed search outcomes. The equilibrium that emerges from this middle ground is inefficient relative to the constrained Pareto allocation. Our theory encompasses the outcomes of the random matching and the directed search literature as limiting cases.
