Module 13 included the term "total national debt." The reason this term applies to social gerontology is: Total national debt can be calculated by age - this gives economists the ability to track how quickly the US Medicare system will go bankrupt. Total national debt can be calculated by age - this shows the "graying of debt."

Suppose that the waiter in a restaurant can either work hard (e = 3) or neglect his duties (e = 0). In addition, suppose that the revenue of the restaurant depends on the \"states of nature\" because they are beyond the control of either the agent or the principal. Formally: $\begin{aligned} R(3) &= \begin{pmatrix} H \\ L \end{pmatrix} \begin{pmatrix} probability \\ 0.7 \\ 0.3 \end{pmatrix} \\ R(0) &= \begin{pmatrix} H \\ L \end{pmatrix} \begin{pmatrix} probability \\ 0.4 \\ 0.6 \end{pmatrix} \end{aligned}$ And the utility of the waiter is denoted by: $U^* = \begin{cases} Ew - e & \text{if he devotes an e level of effort} \\ 20 & \text{if he works at another place} \end{cases}$ where Ew is the expected wage, and e is the effort exerted by the worker. a) Set up the following: i. expected wage equation of the worker if e = 3, and if e = 0. ii. Participation constraint iii. Incentive constraint b) Using the equations for participation and incentive constraints, solve for the wage if the waiter works hard ($w^H$) and if he shirks ($w^L$).

Studies have shown that large amounts of mercury in fish leads to various health problems in consumers. The Food and Drug Administration (FDA) researches and tests Ahi Tuna for mercury prior to distribution. To protect consumers, the FDA recommends that mercury concentration should not exceed 0.4mg. Research has suggested that the level of mercury in farm raised Ahi Tuna could result in lower mercury levels. A sample of 30 farm raised Ahi Tuna resulted in a mercury level of 0.415mg with a standard deviation of 0.07mg. As a new trainee at the Food and Drug Administration, your task is to test whether farm raised Ahi Tuna have mercury levels larger than the FDA suggested level. Calculate the value of the appropriate test statistic. Round your answer to three decimal places.
