In the video about economic decision making, we saw that people: like a wine better if they are told it is more expensive. bring their own bags when rewarded 5 cents for doing so, but not when charged 5 cents for not bringing their own bags usually ignore the price when deciding which item to buy. always prefer to buy the least expensive item available.

Macmillan Learning Sizing Up the Economy Using GDP - End of Chapter Problem a. If nominal GDP rose, does that mean that production had to increase as well? Why or why not? An increase in nominal GDP means there must have been an increase in inputs. means production must have increased. means production must have decreased. may have been due to an increase in the price level. b. What about if real GDP increased? An increase in real GDP means production must have increased because the price level is not held constant. means production must have increased because the price level is held constant. means production must have decreased. may have been due to an increase in the price level. c. Why is it important to use real GDP when comparing changes over time? Changes in real GDP should not be used. We should use changes in nominal GDP when analyzing changes over time. over time will accurately reflect changes in real production. will include changes in the price level, which gives a complete picture. have a time lag, which helps us accurately predict business cycles.

4) Two point masses, $m_1$ and $m_2$, having positions $\vec{r}_1$ and $\vec{r}_2$, interact with each other with a force given by a potential $U(r)$ where $r = |\vec{r}|$ and $\vec{r} = \vec{r}_2 - \vec{r}_1$ is the separation vector between them. Define another vector, $\vec{R} = \frac{m_1\vec{r}_1 + m_2\vec{r}_2}{m_1 + m_2}$ You are to write the Lagrangian of the system in terms of the generalized coordinates $\vec{r}$ and $\vec{R}$ (in a particularly convenient form!). Start by writing the kinetic energy in terms of the generalized coordinates and then rearrange it to get the form: $T = \frac{1}{2}A\dot{R}^2 + \frac{1}{2}B\dot{r}^2$ What are the forms (and meanings) of the constants A and B?

Expected return of a portfolio using beta. The beta of four stocks-G, H, I, and J are 0.44, 0.81, 1.12, and 1.51, respectively and the beta of portfolio 1 is 0.97, the beta of portfolio 2 is 0.83, and the beta of portfolio 3 is 1.11. What are the expected returns of each of the four individual assets and the three portfolios if the current SML is plotted with an intercept of 3.0% (risk-free rate) and a market premium of 10.5% (slope of the line)? What is the expected return of stock G? % (Round to two decimal places) What is the expected return of stock H? % (Round to two decimal places) What is the expected return of stock I? % (Round to two decimal places) What is the expected return of stock J? % (Round to two decimal places) What is the expected return of portfolio 1? % (Round to two decimal places) What is the expected return of portfolio 2? % (Round to two decimal places) What is the expected return of portfolio 3? % (Round to two decimal places)
