This paper proves Li (2009) unawareness structure equivalent to the single-agent propositionally generated logic of awareness of Fagin and Halpern (1988). For any model of one type one can construct a model of the other type describing the same belief and awareness. Li starts from an agent...

We analyze a psychologically-based model of voter turnout in an election with common value and uncertainty. Our model yields distinctive comparative statics results. First, an increase in the proportion of informed citizens may cause the winning margin for the right candidate to either rise or...

Different data frequency is a common problem in many research fields; therefore, it should be handled before a particular study is well under way. Many novel ideas including disaggregation techniques, which are the major interest of this study, have been suggested to mitigate the nuisances of...

This paper develops an algorithm that enables to solve macroeconomic models with Rotemberg pricing and imperfect common knowledge. Under the concept of imperfect common knowledge, Rotemberg pricing requires the solution algorithm to take prices explicitly into account. The state space includes...

We present a novel approach to finite Rational Inattention (RI) models based on the ignorance equivalent, a fictitious action with state-dependent payoffs that effectively summarizes the optimal learning and conditional choices. The ignorance equivalent allows us to recast the RI problem as a...

A nudge is a paternalistic government intervention that attempts to improve choices by changing the framing of a decision problem. We propose a welfare- theoretic foundation for nudging similar in spirit to the classical revealed preference approach, by investigating a model where preferences...

We propose a new approach to modeling the cost of information structures in rational inattention problems, the "neighborhood-based" cost functions. These cost functions have two properties that we view as desirable: they summarize the results of a sequential evidence accumulation problem, and...

We provide a theoretical and empirical analysis of the effects on people's behavior of reminders about investment activities (i.e. with up-front costs and delayed benefits), such as education and healthy behavior. By means of a randomized field experiment, we show that simple weekly reminders...
