justifiably claim an empty slot under ν k . End: The algorithm ends when there is no student who is unassigned or whose assigned school is not the most preferable one among the schools for which she is in the non-rejected status. Then the tentative assignments become final. Obviously, this algorithm may not end in finite steps because of complex reproposal steps. However, owing to these reproposal steps, we allow students to repropose to schools at which they might justifiably claim an empty slot or justifiably envy some student if they did not repropose to. Therefore, though this algorithm may not work well in general, under some conditions it succeeds in producing an assignment and reducing justified envy and claims. First, we will show that CDAAR ends in finite steps when ≻ C has a common priority order for every type and an ordering

How to Measure Welfare Change | 厚生変化をどうはかるか? When the economic environment or market outcome changes, a consumer may be made better off ( 改善 ) or worse off ( 悪化 ). Economists often want to measure how consumers are affected by these changes, and have developed several tools for the assessment of welfare ( 厚生 ).

Substituting into p+q = 3=4, we achieve q = 1=2. Since the game is symmetric, we can derive exactly the same result for Player 1’s mixed action as well. Therefore, we get the mixed-strategy Nash equilibrium: both players choose Rock, Paper and Scissors with probabilities 1=4; 1=2; 1=4 respectively.

Two players, 1 and 2, each own a house. Each player i values her own house at v i and this is private information. The value of player i’s house to the other player j(6= i) is 3 2 v i . The values v i are drawn independently from the interval [0, 1] with uniform distribution. Suppose players announce simultaneously whether they want to exchange (E) their house of not (N). If both players agree to an exchange, the exchange takes place. Otherwise no exchange occurs.

However, it is difficult to assess how reasonable some axioms are without having in mind a specific bargaining procedure. In particular, IIA and PAR are hard to defend in the abstract. Unless we can find a sensible strategic model that has an equilibrium corresponding to the Nash solution, the appeal of Nash’s axioms is in doubt.

where u i (x, θ i ) is the money-equivalent value of alternative x ∈ X. This assumes the case of private values in which player i’s payoff does not depend directly on other players’ types. If it does, then it is called common values case. The outcome (of the mechanism) is described by
