This note explains the equivalence between approximate rationalizability and approximate cost-rationalizability within the context of consumer demand. In connection with these results, we interpret Afriat’s (1973) critical cost efficiency index (CCEI) as a measure of cost (in)efficiency, in...

This paper studies static rational inattention problems with multiple actions and multiple shocks. We solve for the optimal signals chosen by agents and provide tools to interpret information processing. By relaxing restrictive assumptions previously used to gain tractability, we allow agents...

This paper studies optimal monetary policy under rational inattention: the policy maker optimally chooses her information subject to a processing constraint. Our analytical results emphasize how the policy maker’s information choices shape her expectations and the dynamics of the macroeconomy....

After a discussion of cigarette smoking in the context of the Becker-Murphy (1988) model of rational addictive behavior, demand equations are derived accounting for the tolerance, reinforcement, and withdrawal characteristic of addictive consumption. These are contrasted to equations developed...

We introduce a simple method of recovering attention costs from choice data. Our method rests on a precise analogy with production theory. Costs of attention determine consumer demand and consumer welfare just as a competitive firm's technology determines its supply curve and profits. We...

Economists' productivity, as measured by publication in leading journals, declines very sharply with age. Additional evidence shows that this is a rational response to economic incentives and/or changing physical or mental abilities: There is no difference by age in the probability that an...

While the Trump Administration accomplished little of substance, it made progress on one structural objective: casting public doubt on the legitimacy of federal agencies. In particular, the Administration's use of cost-benefit analysis was outcome-oriented and often just bizarre. By deploying...

Predictable polarization is everywhere. We can often predict the different directions that people’s opinions—including our own—will shift over time. Empirical studies suggest that this is so whenever evidence is ambiguous, a fact that’s often thought to demonstrate human bias or...

Rizzo and Whitman’s Escaping Paternalism (2019) is, at once, a scholarly treatise on the nature of rationality and a powerful critique of the use of behavioral insights to support a new paternalism in public policy. Since its recent publication, it has informed research, among other things,...

In standard models of rational learning from experience, prior uncertainties and disagreements recede smoothly as common evidence accumulates. However, this presumes that the underlying risks are relatively stable. Otherwise, rational learners need to sift random noise for signs that the trend...

This paper analyzes a principal-agent procurement problem in which the principal is unaware of events affecting the agent's marginal costs. Since she does not conceive of all relevant events, her planned menu of contracts may be suboptimal. Communication arises naturally as some types of the...

We show analysts’ own earnings forecasts predict error in their own forecasts of earnings at other horizons, which we argue provides a measure of the extent to which analysts inefficiently use information. We construct our measure by exploiting two sources of variation in analysts’...

We review the recent literature on rational inattention, identify the main theoretical mechanisms, and explain how it helps us understand a variety of phenomena across fields of economics. The theory of rational inattention assumes that agents cannot process all available information, but they...

We study the allocative challenges that governmental and nonprofit organizations face when tasked with equitable and efficient rationing of a social good among agents whose needs (demands) realize sequentially and are possibly correlated. As one example, early in the COVID-19 pandemic, the...

In recent months, the governors of several states have suffered major political embarrassments because actual revenues fell, substantially short of the predictions in their respective budgets. Such episodes focus attention on the question of whether states do a "good" job of forecasting...

In electronic commerce (e-commerce)markets, a decision-maker faces a sequential choice problem. That is, the objects come sequentially before the agent in this choice problem and a third party intervention plays an important role in making purchase decisions. For instance, while purchasing...

The main purpose of this research is to understand the patterns of consumption of addictive goods, their economic and welfare consequences for society and the long-run effect of tax policy in a dynamic general equilibrium model of rational addiction. In contrast to prior research, we allow...

We review the recent literature on rational inattention, identify the main theoretical mechanisms, and explain how it helps us understand a variety of phenomena across fields of economics. The theory of rational inattention assumes that agents cannot process all available information, but they...

Recent theoretical and empirical work characterizes attention as a limited resource that decision-makers strategically allocate. There has been less research on the dynamic interdependence of attention: how paying attention now may affect performance later. In this paper, we exploit...

Using illustrations from research on inequality, this paper offers evidence on the strengths of 'behavioural synthesis', i.e. the reconciliation between neoclassical and behavioural economics. We compare how theoretical models of absolute and relative inequality have evolved from assumptions of...

Expected utility theory (EUT) is currently the standard framework which formally defines rational decision-making under risky conditions. EUT uses a theoretical device called von Neumann-Morgenstern utility function, where concepts of function and random variable are employed in their...

Objective: The objective of the article is to refer to the thesis about the need to modify the main paradigm of economic sciences - by which we mean mainstream economics - with all its consequences that influence the whole economic sciences. We posit the need for the modification of how economic...

In economic theory, an agent chooses from available alternatives-modeled as a set. In decisions in the field or in the lab, however, agents do not have access to the set of alternatives at once. Instead, alternatives are represented by the outside world in a structured way. Online search results...

The rational choice model of voluntary public good provision predicts that an individual's contribution to climate change mitigation responds negatively to larger contributions by others whereas social norm theory maintains that one's own contribution is positively related to that of others....
