Q: Proving a (Representing Utility) Function is Continuous

I sincerely apologize for posting such a long question. The question involves a complicated proof of a theorem in mathematical economics. I feel it will be better for me to state my question first. I will add all related background information afterwards. So here is my question: I need to prove t...

Optimal stopping

In mathematics, the theory of optimal stopping or early stopping is concerned with the problem of choosing a time to take a particular action, in order to maximise an expected reward or minimise an expected cost. Optimal stopping problems can be found in areas of statistics, economics, and mathematical finance (related to the pricing of American options). A key example of an optimal stopping problem is the secretary problem. Optimal stopping problems can often be written in the form of a Bellman equation, and are therefore often solved using dynamic programming. == Definition == === Discrete... ===

A: Tag management 2022

Merge the tags economics and mathematical-economics under the umbrella economics. The latter has only recently been created and is not distinct from the former, at least not from reading the tag descriptions nor the usage of each tag. Notice that all economics questions in MSE are really about ma...

The tag mathematical-economics now has a tag-excerpt and a tag-wiki. (Copy-pasted from Wikipedia.)

@MartinSleziak economics and mathematical-economics should be synonyms, or the latter should be eliminated (e.g. notice there is no tag for "mathematical finance" and all such questions fall under finance)

Q: A question about "welfare independence"

I am working on some applications of measures of inequality (economic inequality). Upon reading a paper by Kolm (Kolm, S. C., Unequal Inequalities. I, Journal of Economic Theory, 12 pp 416-442, 1976) I found a result that I found intriguing and for which I would like to know if any one has a refe...

Q: Proof: if the preference relation $\succsim$ is continuous, then the upper contour set is closed

I am having some trouble with this demonstration. I know that the definition of continuous preference relation is: $$\succsim \text{is continuous iff } \forall \text{ pair of sequences } \{x^n\}_{n>0} \text{ and } \{y^n\}_{n>0} \text{ such that } x^n\succsim y^n \ \forall n, \ x^n \rightarrow x...

Q: Modeling The Tragedy of the Commons

I was wondering if anyone would like to review the following paper: https://www.academia.edu/44399836/ON_A_SIMPLE_MATHEMATICAL_MODEL_OF_THE_TRAGEDY_OF_THE_COMMONS?source=swp_share It tries to model the resource population of a commons (like the number of fish in a pond) numerically as some number...

Newsvendor model

The newsvendor (or newsboy or single-period or perishable) model is a mathematical model in operations management and applied economics used to determine optimal inventory levels. It is (typically) characterized by fixed prices and uncertain demand for a perishable product. If the inventory level is q {\displaystyle q} , each unit of demand above q {\displaystyle q} is lost in potential sales. This model is also known as the newsvendor problem or newsboy problem by analogy with the situation faced by a newspaper...

Matching theory (economics)

In economics, matching theory, also known as search and matching theory, is a mathematical framework attempting to describe the formation of mutually beneficial relationships over time. Matching theory has been especially influential in labor economics, where it has been used to describe the formation of new jobs, as well as to describe other human relationships like marriage. Matching theory evolved from an earlier framework called 'search theory'. Where search theory studies the microeconomic decision of an individual searcher, matching theory studies the macroeconomic outcome when one or more...
