04 -51 (1 point) leta -5 0 we can find the determinant of a by using row reduction: l-20-25 -1 -4-5 01 first we swap the first and second rows to get0 4-5 l-20 -251j by what factor does this change the determinant? 20 25 0 next we multiply the first row by-5 to get 0 4-5 -20-25-1 by what factor does this change the determinant? [20 25 0 finally we replace the third row by the sum of itself and the first row to get 0 4 -5 0 0 1 by what factor does this change the determinant? since the determinant of the row reduced matrix is the determinant of a is

Whether candidate 1 or candidate 2 is elected depends on the votes of two citizens. the economy may be in one of two states, a or b. the citizens agree that candidate 1 is best if the state is a and candidate 2 is best if the state is b. each citizen's preferences are represented by the expected value of a bernoulli payoff function that assigns a payoff of 1 if the best candidate for the state wins (obtains more votes than the other candidate), a payoff of 0 if the other candidate wins, and payoff of 1/2 if the candidates tie. citizen 1 is informed of the state, whereas citizen 2 believes it is a with probability 0.9 and b with probability 0.1 each citizen may either vote for candidate 1, vote for candidate 2, or not vote. a. construct the table of payoffs for each state of the world and draw the rectangles to get a diagram that represents this game (each player has three actions: vote for candidate 1, vote for candidate 2, or abstain). b. show that the game has exactly two pure strategy bayesian nash equilibria, in one of which citizen 2 does not vote and in the other she votes for 1. c. why is "swing voter's curse" an appropriate name for the determinant of citizen 2's decision in the equilibrium where he abstains?
