This paper demonstrates how simple general equilibrium models can be solved with the help of Microsoft Excel. Two different general equilibrium models for tax incidence analysis are used as illustrative examples. The methods presented here are intended to be beneficial to both students and...

An obstacle to the teaching of principal-agent theory is the technical complexity and intractability of the general model. Even in academic studies strong assumptions are often imposed so as to derive an analytical solution. The author describes a graphical approach to the standard...

Dynamic models are increasingly used in economics, especially in macroeconomics. However, the skills required for constructing and analyzing dynamic models are advanced relative to those required for static models. Consequently, dynamic models are difficult to introduce into courses where the...

La publicación presenta las técnicas matemáticas de optimización aplicadas al análisis económico y cubre los tópicos de programación matemática, optimización dinámica y teoría de juegos.

We define a standard optimization problem with quadratic objective function and provide a rigorous visual proof for its solution without using calculus. We then show that such standard problem is a building block for several economic models related to microeconomics, game theory and pricing...

Few textbooks in mathematical economics cover optimal timing problems. Those which cover them do it scantly or in a rather clumsy way, making it hard for students to understand and apply the concept of optimal time in new contexts. Discussing the plentiful illustrations of optimal timing...
