Intermediate Micro: Math ReviewIntermediate Micro Math: Exponents Review A quick review of all of the exponents rules, including fractional exponents and negative exponents, and how to simplify them.Equations with strange exponents Solving equations like x0.4 = 10 on your calculator.Level Curves (Indifference, IsoQuants...) How to graph a level curve, or parametric curve. If Q=x*y=4, how do we graph this curve. Useful for isoquants and indifference curves in Intermediate Micro.Level Curves Visualization More of the above with better visualization, with a at z=4.  *FILE LevelCurvesintro.wxm*   Basic Derivatives & Micro: NEWHere we review derivatives of polynomials, and the interpretation as a slope, or marginal.Partial Derivatives & Micro (NEW)A look at partial derivatives, and a little bit about how we can use & interpret them in Econ.  Basic Derivatives & Micro (OLD) Here we review derivatives of polynomials, and the interpretation as a slope, or marginal.More on Partial Derivatives  (Old) I review the idea of a one-variable derivative again, then discuss partial derivatives in more depth.Quick Calculus for Economics 1: Derivatives and Integration Introduction and integration to find variable costs, total benefit, consumer surplus, and producer surplus.Quick Calculus for Economics 2: Integration to find variable costs, total benefit, consumer surplus, producer surplus, and deadweight loss with a production quota.

Intermediate Micro: Basic/Review MaterialEquilibrium and Comparative Statics: Basics Example of calculating equilibrium of Supply and Demand using algebra and graphing, and using "comparative statics": examining what changes when an exogenous variable changes the equilibrium.Add Linear Demands How to add two linear demand functions together to get a total demand function.Adding Nonlinear Demands Here we add two Cobb-Douglas Demands and plot them using Maxima *File maxima add cd demands.wxmDemand, Marginal Revenue, and Profit Another example of looking at demand, along with marginal revenue.   How separating markets can increase profits.Supply Shocks & Equilibrium: ANWR Example Here I discuss a problem similar to one in Jeffrey Perloff's Text: How could we model how drilling in ANWR could help keep prices down when a supply shock happens.Elasticity and Tax Incidence A brief review of tax incidence, and of how price elasticity of demand and supply can predict the incidence of a per unit tax.Demand and Elasticity 1 Given two points on a demand curve, find the equation and calculate elasticities.From Elasticities to Linear Supply and Demand Here I show how to take price elasticities of supply and demand to derive plausible linear functions to represent them.Demand elasticity back of envelope  Using the price elasticity of demand, price and quantity, we approximate the demand function for Jack Daniels whiskey in Virginia
Intermediate Micro: Intermediate Surplus and deadweight loss analysis Cost Functions, Marginal Cost, and Perfect Competition Here is a basic look at cost functions, and using calculus to figure out how many units a perfectly competitive firm should produce, and its relationship to Producer Surplus.Ceiling Worst Case Scenario With a price ceiling, what you normally calculate in Introductory Micro is the "Best Case Scenario".  Let me show you the Worst Case Scenario, or "Least efficient Outcome".
Maximum Tax Revenue: Take your skills to the next level In this video we derive the tax-revenue maximizing per-unit tax. First with a graph, then with example equations, then derive the analytical solution. Extremely fun way to see mathematical economics in action! Handout Intermediate Micro: Preferences, utility functions, and Indifference Curves  Utility 1 A look at a total and marginal Utility Function with only one variable. Using calculus, we look at what a marginal function means.Utility 2a Visualizing a 3d utility surface, thinking about marginal utility. In this video we only do visualization so that you can better understand the calculus that comes next.  *File Utility.wxm*Utility2B: Marginal Utility and MRS Using calculus to find marginal utility and marginal rate of substitution for a utility function, looking at indifference curves. Utility2C: MRS for Cobb Douglas  I show a trick for finding the Marginal Rate of Substitution function if you have a cobb Douglas utility function. Works for MRTS (marginal rate of technical substitution) as well.Indifference Cures: Different Types We look at intuition, graphs, functions of several types of preferences people could have: Cobb Douglas, Quasilinear, perfect complements/substitutes, bads, and goods we could take or leave.A few points about Indifference Curves Some of the finer points: Why they can't slope upwards (with two GOODS), cross, be thick, there are infinitely many, and a review of MRS.Utility3: Maximizing Utility with Budget Constraint How to solve a constrained optimization problem with a utility function and budget constraint; maximizing utility. Just set the slope of the budget line = slope of indifference curve! Quasilinear Utility Maximization Instead of the usual Cobb-Douglas, here I illustrate maximizing utility with a quasi-linear utility function.Equal MU per \$, or Bang for Buck rule Graphs, calculus, numbers, and discussion to explore details of the =equal marginal utility per dollar maximization condition.Utility Maximization and Demand Here we demonstrate how to show where demand curves come from, by doing several utility maximization problems.U Max and Demand  New Version! Also includes Price Consumption and Income Consumption Curves Download HandoutThe Dual Problem Here we look at the DUAL problem to utility maximization. Instead of getting the highest utility with a given budget, here we find the cheapest way to attain a certain level of utility.
Income and Substitution Effects If you already know how to maximize utility, this video shows you how to find income and substitution effects using the Slutsky Equation (Hicks' Decomposition). Income/Subs Effects, Price Decrease Here we look at a Cobb-Douglas utility function with a price decrease.Overview: Inc/Subs/ Compensating/ Equiv. Variation. This is an overview of graphing and interpretation of income and substitution effects, and compensating and equivalent variation. A focus on graphing and interpretation, rather than on calculation. *File* INCSUBS INTERPRETWhy Subsidies Suck! Using Consumer Theory to show why subsidies are inefficient.   *File* Subsidies Suck.pdfYet Another Example  Utility Maximization, Price Change, Income and Substitution Effects, and Compensating Variation file: income.subs.another.example.pdf
Intermediate Micro: Cost Minimization and Production FunctionsMRTS and Elasticity of Substitution Production functions, non-economic regions, interpreting marginal rate of technical substitution, perfect substitutes and perfect complements (Leontief production functions), and the elasticity of substitution measure.IsoQuants and Returns to Scale Here we look at the definition of returns to scale, isoquants, and Cobb-Douglas Production Functions. As usual, I give you the shortcuts along with the intuition and math. I briefly describe the difference between RTS and marginal returns.Production Theory: Cost Min 1 *File* IM Production Theory Example Returns to scale, input demand functions, marginal rate of technical substitution, isocosts, isoquants, etc. SR vs. LR cost minimization. Production Theory: Cost Min 2 Continuation of above, Returns to scale, input demand functions, marginal rate of technical substitution, isocosts, isoquants,etc.A interesting discussion of a boring problem Given L, K, and the exponents, solve for the constant.  Why would we want to do this? Here are some things to think about.
