Q3 a) A researcher wants to find out what are the factors which determine the number of installs (I) of an application (app) from a famous app store. Size in Mbs (S), Reviews in *000s (Re), Ratings (0 to 5) (Ra), Price in 'Rs (P). She ran the following regressions: log I = 1.329 + 0.2356 S+0.4320 log(Ra) – 0.2678 P + 1.928 log(Re) Se = (0.63) R? = 0.734 (0.242) (1.29) (0.001) (0.156) df = 156 i. Interpret the regression above. ii. Test for statistical significance of Price in the model. Depending on the result do you suggest that price is a significant factor affecting app installation? iii. Suppose the regression is re-estimated where number of installs (I) varies only with respect to price (P). Average I in sample is 5 and average P is Rs 8.9. Following regression was estimated: Î = 52.351 + 3.139 - 1 se = (37.39) (0.0187) df = 156, R? = 0.806 How would you interpret this model? Explain the shape of the curve. iv. What would be the slope and elasticity of number of installs with…

A individual, with a utility function lnW and an initial wealth level W0, is faced with a fair gamble of winning or losing $h (where W0 > h > 0) with 50-50 chance. (a) Is this individual risk averse? Explain.(b) Suppose that the individual is willing to pay up to an amount of f in order to avoid such a gamble. Give the equation that determines f, and solve the equation for f (i.e., express f in terms of W0 and h). (c) Show that f increases as h increases.
