A temporary TFP shock: Suppose the economy is hit with a temporary positive TFP shock. For example, suppose weather conditions are temporarily very favorable for agriculture.
(a) Analyze the effect of the shock in the labor market diagram of a standard DSGE model (with no sticky prices or wages). What is the effect on the real wage and employment in the short run?
(b) How would your answer change if there are sticky prices? Discuss how your answer relates to the impulse response functions shown in previous Figure.

Use the general factoring strategy to completely factor each polynomial. If the polynomial does not factor, then state that it is nonf actor able over the integers.

Suppose that an economy is divided into four sectors (agriculture, manufacturing, services, and entertainment) with the following input-output matrix:

$$\begin{equation*}C=\begin{bmatrix}.12&&.11&&.15&&.18\\.20&&.08&&.24&&.07\\ .18&&.16&&.06&&.22\\ .09&&.07&&.12&&.05\end{bmatrix}\end{equation*}$$

What amount of input from the services sector is needed for a gross production of $50 million by the entertainment sector?

Madison Finance opened two branches on September $1\space (t = 0)$. Branch $A$ is located in an established industrial park, and branch $B$ is located in a fast-growing new development. The net rates at which money was deposited into branch $A$ and branch $B$ in the first $180$ business days are given by the graphs of $f$ and $g$, respectively. Which branch has a larger amount on deposit at the end of $180$ business days? Justify your answer.

BUSINESS: Car Loan Rates From 2006 to 2010 , new car loan interest rates at auto finance companies were approximately

$$I(x)=0.317\left(x^2-9.44 x+23\right)\left(x^2-2.19 x+2.27\right)$$

percent where x is the number of years after 2005 . Differentiating using the product rule, find $I^{\prime}(4)$ and $I^{\prime}(5)$ and interpret your answers.
