Consider the following estimated regression: $\hat{y} = 13.78 - 5.2 \ln M$ Where $\text{se}(\beta_2) = 2.26$ and $R^2 = 0.545$. Note that $y = $ rate of interest on 1-year bonds; $M = $ the money stock (billion dollars). It is argued that when central banks increase (decrease) the money supply, interest rates fall (rise). Interpret the slope coefficient and then test whether the evidence supports this view with $\alpha = 0.05$ significance level. ($N = 45$)

Fig. 6.1 shows a hydroelectric power station, Fig. 6.1 (a) On Fig. 6.1 complete the boxes by filing in the forms of energy in the hydroelectric power station. $ [2] $ (b) Water of mass $ 100000 \mathrm{~kg} $ falls $ 50 \mathrm{~m} $ from the upper lake onto the turbine. Calculate the decrease in potential energy of the falling water. energy $ = $ 421 (c) The energy output from the generator is $ 15 \% $ of the energy the water has in the upper lake. Suggest one possible way in which energy is wasted.

For the following problem, recall that the area of a rectangle is equal to the product of its length and width. The perimeter of a rectangle is equal to the sum of the measures of its sides. (a) In the picture above, a total of 200 feet of fence is used to create two identical rectangular enclosures. Construct a function A(w) that represents the total area surrounded by the two enclosures, where w denotes the width of each of the enclo- sures in feet. (b) Using the function from part (a), determine the total area surrounded by the two enclosures if the width of each one is 20 feet.

The Solow model (see SF Macro or several JS courses) predicts that what is called "conditional convergence" holds, but that "unconditional convergence" does not. Unconditional convergence is when all countries converge to the same levels of income per capita, for this to be the case, the poorer the country the faster it should grow on average if it is to reach the same level of income per capita as richer countries. Conditional convergence is when, on average, poorer countries grow faster than rich countries, taking into account other differences between the countries. Unconditional convergence would imply that β is significant and less than zero so that the poorer the country the greater the subsequent change in income per capita.
