2. A homothetic taste can be represented by a utility function that is homogeneous of degree $k$, i.e., $U(tx_1, tx_2) = t^kU(x_1, x_2)$, for $t \neq 0$. Then the homothetic taste can always be represented by a homogeneous utility function of degree 1.

2.19. The decomposition of reactant A at 400°C for pressures between 1 and 10 atm follows a first-order rate law. (a) Show that a mechanism similar to azomethane decomposition, p. 21, A + A \leftrightarrow A* + A A* \rightarrow R + S is consistent with the observed kinetics. Different mechanisms can be proposed to explain first-order kinetics. To claim that this mechanism is correct in the face of the other alternatives requires additional evidence. (b) For this purpose, what further experiments would you suggest we run and what results would you expect to find?

Entered $84.20 Answer Preview Result $84.20 Incorrect The answer above is NOT correct. (1 point) In this chapter, assume the log-normal model. Unless otherwise stated, assume no arbitrage opportunities The current spot price of a stock is $73.00, the expected rate of return of the stock is 9.8%, and the volatility is 19%. The risk-free rate is 4.7%. Compute the price of a derivative whose payoff in 18 months is - $13.00 if the stock price in 18 months is below $78.00, - $6.00 if the stock price in 18 months is between $78.00 and $87.00, - Nothing if the stock price in 18 months is greater than $87.00 Enter your solution as a dollar value, including dollar symbol ($), to two decimal places. $84.20
