Anybody have any idea how I should approach this (what to look for in books etc), I've missed loads of uni and dont know where to start:

Consider 2 consumers. One has utility function u( X1, X2) and the other has utility function g(u( X1, X2)) where g(-) is a monotonic increasing function. Show that the consumers have the same demand functions.

Any suggestions much appreciated

Is g(-) the first derivative of g, the opposite of g, or just g?

Defend or refute the following statements:

a. "If the income and substitution effects of a rise in the price of a good both cause consumption of the good to fall, the good is inferior"
b. "A peasant farmer allocates his entire budget to two goods; rice and beans. If rice is an inferior good."
c. "Increases in interest rates increase the utility of net savers, but decrease the utility of net borrowers.

Also,

Both persons A and B, have identical preferences, and identical wage rates. A has no non-labor income, but B receives a non-labor income (husband's pension). Assuming that leisure is a normal good, who will work more hours??

Thanks so much!!
