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...

Dynamic optimization is widely used in financial economics, macroeconomics and resource economics. This is accounting for some friction between the undergraduate and graduate teaching of economics because most undergraduate programs still concentrate on static economic analysis. This paper shows...

Monotone methods enable comparative static analysis without the restrictive assumptions of the implicit function theorem. Ease of use and flexibility in solving comparative static and game theory problems have made monotone methods popular in the economics literature and in graduate courses, but...

In introductory and even intermediate courses, the cobweb model is the reference dynamic model to justify market equilibrium and to illustrate how market equilibrium can be reached. Nonetheless, the cobweb model has at least two unattractive features: (i) that, in requiring at each time equality...

The objective of this manuscript is to provide a simple guide to instructors and students on how to solve and simulate a discrete-time specification of the Life-Cycle/Permanent-Income Model of Consumption and Saving (LCPI Model) using only algebra and basic calculus. The solution and simulation...

Spanish Abstract: Al enseñar los modelos de equilibrio general los libros de texto de microeconomía se centran en las ideas que se pueden extraer del diagrama de Edgeworth para el intercambio. Las herramientas necesarias para analizar matemáticamente los modelos de equilibrio general abruman...

This textbook provides all tools required to easily solve intertemporal optimization problems in economics, finance, business administration and related disciplines. The focus of this textbook is on 'learning through examples' and gives a very quick access to all methods required by an...

Hidden type contracts are examined in their simplest formulation in order to fully prove the role of the single crossing property to eliminate rendundant constraints and to show how this necessary condition constrains the parameters in the case of linear functions. Mechanism design examples are...

We present a simple method of solving first-order linear differential and difference equations with a constant term and a constant coefficient. When solving such equations standard books in mathematical economics resort to a particular integral and a complementary function without further...

In this paper, we analyze a purchase lot-sizing decision that includes transport cost using actual motor carrier freight rates. Lot-sizing models in the literature either estimate motor carrier freight rates with a continuous function or simplify less-than-truckload freight rates unrealistically...
