Subgame perfection is a refinement of Nash Equilibrium that requires Select one: Oa credibility/rationality at every pointipath in the game, regardiess of whether those pointa/paths are actualy part of the Nash equilibrum Ob focalness in equilibrium Oc. credibility/rationality only along the equilbrium path O d. firms do not cheat on their output agreements Oe perfect and skilled play by all piayers

6. Consider the following two-player game: 2 L M U 3,3 2,3 1 M 2,1 3,1 D R 0,2 3,3 0,3 3,0-5, -5 a. Find all pure NE. b. Find a (non-pure) MNE in which player 1 (the row player) plays a pure strategy. c. (Harder Question) Show that there cannot be a CE prescribing that strat- egy D of player 1 (the column player) is played with positive probability.

Little Kona is a small coffee company that is considering entering a market dominated by Big Brew. Each company's profit depends on whether Little Kona enters and whether Big Brew sets a high price or a low price: Little Kona True True or False: Only Little Kona has a dominant strategy in this game. False Big Brew High Price Low Price Enter $2 million, $3 million $2 million, $1 million Don't Enter 50, 58 million $0, $3 million Which of the following outcomes represent a Nash equilibrium in this case? Check all that apply. Big Brew maintains a high price and Little Kona does not enter. Big Brew maintains a low price and Little Kona does not enter. Big Brew maintains a high price and Little Kona enters. Big Brew maintains a low price and Little Kona enters. Big Brew threatens Little Kona by saying, "If you enter, we're going to set a low price, so you had better stay out." Thin True or False: Little Kona should believe the threat.

I need a good explanation on this question please. Is there really a strategy here? I'm confused since mixed strategies are not allowed.
