Try to assume that you are at the edge of the city. The differentiate profit with respect to k. The find expression for k is a function of price at edge and exogenous parameters. Backinsert this into profit expression and use that profit is equal to 0 and solve this for price at the edge as a function of exogenous parameters. Insert Marshall demands into utility function and get valuefunction. Insert price at edge in valuefunction to get utility at edge. Then use that utility is the same everywhere. Get (14) by setting valuefunction equal to u-bar and inverting valuefunction to solve for P(x).

Then insert the expression for P(x) into expression for Marshall demand to get (15) ... try it ... if you can follow the instructions or I made mistake let me know :) good luck.

# Help with Deriving Hicksian Demand in the Monocentric City Model?

(Asked by: username_0 on 2024-06-26)

I have a fairly standard Alonso-Muth-Mills model, but struggling to derive the Hicksian demand.

Starting with the basic utility function:[![enter image description here](https://i.sstatic.net/Gc2PrbQE.png)](https://i.sstatic.net/Gc2PrbQE.png)

And this Budget Constraint: [![enter image description here](https://i.sstatic.net/CbMGho0r.png)](https://i.sstatic.net/CbMGho0r.png)

Housing Floor-space is subsequently added in:[![enter image description here](https://i.sstatic.net/QFf2cqnZ.png)](https://i.sstatic.net/QFf2cqnZ.png)

**My ask: Now this is where I am confused: How is U-bar, P(X) and H(X) derived?**
