### Topological concepts in economic theory

I strongly suspect that an emerging important area for applications of measure theory will be in approximate dynamic programming techniques. Approximate dynamic programming (aka "reinforcement ...

### Topological concepts in economic theory

This was too long for comment. "Post 1960" seems an arbitrary and very high bar for an applied field, including micro theory. Most of the topics you name would not be considered contemporary ...

### Topological concepts in economic theory

Measure theory is widely used in the problem of fair division (aka "cake-cutting"). See the many papers about fairness in economics journals. For a particular example, see Tatsuro Ichiishi and Adam ...

### Topological concepts in economic theory

Loeb spaces have been used to model situations with a continuum of agents. See http://eml.berkeley.edu/~anderson/Book.pdf and the chapters by Sun on economic applications in the book Nonstandard ...

### What are the recent advancements in building a unified theory of bounded rationality?

The term bounded rationality was introduced by Herbert Simon. He wrote "The term, bounded rationality, is used to designate rational choice that takes into account the cognitive limitations of ...

I think you're referring to the decoy effect. A popular example of this is the Economist subscription puzzle, popularized in Dan Ariely's TED Talk (starting at 12:22).

### Do people really care about higher moments?

Perhaps there is some evidence toward your claim, but I would argue that in most situations, people do not use point estimates (although some "smoothing" likely occurs). In particular, there is no ...

Empirical Evidence on rational inattention: -Title: Attention Discrimination: Theory and Field Experiments with Monitoring Information Acquisition, Authors: Vojtěch Bartoš, Michal Bauer, Julie ...

### What are the recent advancements in building a unified theory of bounded rationality?

One recent paper that is being positioned as a very wide-ranging theory of bounded rationality (although certainly it doesn't come close to capturing every insight in the field) is Gabaix's ...

### Tests of rational inattention

The following two papers by Andrew Caplin and Mark Dean focus on tests of rational inattention in a lab setting (i.e. with data one could in principle find the field). As BB King said, I won't do it ...

### Luce Choice Axiom, Quantal Response Equilibrium

A few quotes from Jessie and Saari (2015) may be of interest. Regarding Luce Choice Axiom (LCA): The effect of LCA is to endow each alternative with an intrinsic level of likelihood that is ...

### Bounded rationality with Quantal Response Equilibrium model for an Extensive Form game

I'm not sure what capacity allocation games you're applying QRE to. But here's a very stylized example where QRE is applied to an asymmetric game where the strategy spaces of the two players are (...

### Was there resistance, historically, to the idea that human behavior deviates from rational decision making theory?

I would recommend reading Thaler's Misbehaving, which chronicles the development of behavioral economics as a field and its struggle to gain recognition by mainstream economists. Several of its ...

### Doubts in modelling the Arthur(1991) paper: Designing economic agents that act like human agent

Although I still don't understand what these "strengths" are all about, still, mechanically, step $4)$ is now clear. At each point in time, there is a certain allocation of Strengths to actions, \$\{...

### Random Choice interpretation

I don't feel these two interpretations are mutually exclusive, they belong to different sides of the same problem - one is empirical the other is theoretical. The conflict you seem to see between ...

### Why does a model that is used for policy analysis needs its shocks and parameters to be structural (= invariant) to the shock under consideration?

This is due to the famous Lucas critique. To make long story short, in the past in the heyday of Keynesian macroeconomics it was quite normal for macroeconomists to just postulate some relationships ...

### What is the difference between a perfect foresight equilibrium and a rational expections equilibrium?

This is not a formal definition, but a useful piece of intuition. I think that the best way to think about it is that when there is uncertainty in a model it arises mainly in two forms either there ...

### Expectational stability: adaptive learning of RE equilibria in dynamic systems

These are many questions. O.k., so let's go step by step: (Q1) What is a mapping actually? A map is just another term for a function. Here, every "law of motion", the actual one (ALM) and the ...

### Difference between equilibrium and k-rationalizability

What is meant by fixed point reasoning here? Specifically, Nash equilibria. One way to define a Nash equilibrium in words is "a strategy profile from which no player can be made better-off by ...

### Sunk cost fallacy- is it a bug or a feature?

Very interesting question. To answer the direct question in the title, I'd say I'd have to break the sunk cost fallacy into two arenas. In the first I'd say it is a feature not a bug, but in the ...

### Do people really care about higher moments?

I think there is a missing concept in your question. If you are discussing simple gambles and not things like the stock market, then the distributions that are involved usually have sufficient ...

### Topological concepts in economic theory

Beside the work of Chichilnisky mentioned by Michael, another interesting use of topology in social choice theory appears in the work of Redekop on Arrow's theorem on economic domains. Redekop, J. (...
