### Microeconomics undergraduate ELASTICITY help (differentiating log-linear demand curve) [closed]

How do you show that the price elasticity of demand is a constant if the demand function is log-linear? To show this, how do you differentiate the log-linear demand curve to determine dQ/dp, and ...

### Log log regression with fixed effects and cross elasticity of demand

I have a time series of units sold, and price. I'd like to calculate elasticity of demand wrt to price and a few other variables, some of them are fixed effects. ...

### What is the empirical price elasticity of demand for insulin?

A lot of textbooks say that demand for insulin is perfectly inelastic. I don’t think this is quite true (and I am a type 1 diabetic). It’s clearly very inelastic, but not perfectly so. There are ...

### Regression approximation for the rate of change in occupancy rate of residential market with respect to price

I have historical data on occupancy rates for a given neighborhood, along with characteristics and other local economic variables. I am looking to estimate the regression equation with occupancy rates ...

### Piketty's explanation of elasticity of substitution (from his book Capital in the 21st century)

I have some trouble following the explanation of the elasticity of substitution between capital and labor and its implications on p189. Take this part: The relevant question is whether the elasticity ...

### Terminology, is elasticity used as “mean elasticity”?

Given a demand $q$ and a price $p$ sutch that $q=q(p)$, the elasticity of demand is given by, $\epsilon = \frac{p}{q}\frac{dq}{dp}$ which depends on the price. But, when reading papers about ...

### elasticity from inverse demand

I was wondering of my thinking here was right: Given $$e=\frac{dQ}{dp}*\frac{p}{Q},$$ where $e$ is elasticity, $dQ/dp$ is first derivative of demand function, $p$ is price and $Q$ is quantity. ...

### Is oil supply really inelastic in the short term

Is oil supply really inelastic in the short run? Though it remains evident that in the short run, the known capacities of oil can't be increased and hence we can assume that there remains a upper cap ...

### Elasticity of substitution

So, this is an economics question but the problem I have is a pure math problem I guess. So I have the following equation:f(x,y) this function have the elasticity of substitution(EOS): 1/(1-beta). a,...

### Confidence Intervals for Elasticity in Simple Linear Regression

I'm pretty sure this is a very simple question that I am missing something obvious. I have a simple linear regression with multiple independent variables. I want to calculate the elasticity (no ...
