2. Suppose an exclusive art club charges RM50,000 as an annual membership fee and there are a total of 150 members. Assume general income has increased by 4% and the income elasticity of demand for the art club membership is 5%. Due to this change, the overall total number of members has increased by 10. How much has the club's membership increased due to the change in income and due to network effects? Include a graph in your explanation and show the necessary calculations. Label the graph axis with the appropriate numerical values.

Check all the properties of the logistics DDS that are true: 1) The logistics DDS is more realistic than the exponential model because it takes limitations of the environment into account. 2) The logistics DDS has a quadratic undating function. 3) The logistics DDS has 2 equilibrium values, the trivial one at zero and the non-trivial one at the carrying capacity. 4) The logistics DDS has unlimited growth because it is a power function 5) Both of the equilibrium values of the logistics DDS are stable.
2. Explain how each of the following factors may affect LRAS and SRAS respectively. In particular, explain whether and in which direction each of the building blocks of LRAS and SRASS – viz., labor supply (N*), labor demand (Nd), capital supply (K*), capital demand (K“), and the production function – as well as the aggregate supply (AS) curves themselves may shift in response to the changes below. (a) A rise in the labor force participation rate (LFPR).

1. Consider the following four demand functions for money: (1) InM," = a, +a,InY," + a, In R, + a, In P, + u, (2) InM," = ß, + B,lnY, + ß, In R, + ß;, In P, + u,2 where M,", Y,", R, and P, denote, respectively, aggregate nominal money demand, aggregate national income, long-term interest rate, implicit price deflator. These two money demand equations are estimated for the period 1949-1965 and the following estimated equations are obtained: (1) InM," = 3.999 +1.710lnY," – 0.608 In R, – 0.759 In P, R² = 0.942, SSR = 0.080 (0.469) (1.801) (0.416) (2) InM," = 3.999 +1.710lnY, – 0.608 ln R, +0.9519 ln P, (0.651) R² = 0.942, SSR = 0.080 (1.801) (0.416) (0.469) (0.651) (b) In Model (2) test the hypothesis that the price level has no significant effect on real money demand using t and F statistics.
