I have not heard of Frisch demand before, and fail to understand how it is calculated from your example. (What is $\lambda$?) Could you please explain how it is calculated or refer to an explanation?

@Giskard its a a quantity determined by prices and the marginal utility from money $\lambda$, this is from your standard utility maxization problem. From what I understand this $\lambda$ term embodies a the complicated allocation process each dollar that enters our consumer's hand goes through.

Frisch demands are demand equations found usually in an intermediate step of the standard utility maximization problem. By example for the basic two-good case of a consumer with quasilinear preferences:
$$U(x,y)=y+\ln (x)$$

the corresponding Frisch Demand is:

$$x^f(\lambda,\text{p})=\frac{1}{\lambda p\_x}$$

In general what are Frish demands useful for on their own? What Questions do they answer?
