say you have 20 observations across time on 10 individuals each. Assuming that the unobserved effects are uncorrelated with the independent variables, what model specification would be appropriate for the following estimation:

(i) individual specific intercepts differ, slopes across individuals are equal but the variance of the error term differs across individuals

(ii) individual specific intercepts differ, slopes across individuals are equal but the errors are contemporaneously correlated across individuals in the same time period

Suppose there is a joint project that generates an amount 10 for each of the individuals A and B, provided the sum total of A's and B's investments in the project is at least 7. Suppose A's investment is denoted by x and B's by y, where x and y can take any values in {0,1,2,3,4,...,8,9,10}. A player always has to incur the cost of the investment (equal to x or y respectively) and gets the benefit if and only...
