Export Subsidies (under perfect competition) in a small country a.

Suppose Boeing is more efficient at making airplanes than Airbus. Starting from slide 33, Figure 10-9, let’s change the payoff matrix, so that if Boeing and Airbus both produce, Boeing gets +5, instead of -5. And, if Boeing produces, and Airbus does not produce, Boeing gets +125 instead of +100. Will there be a unique equilibrium in this case?

1. Export Subsidies (under perfect competition) in a small country
a. For a small country, is the logic for why export subsidies provide negative gains
different than the logic for why import tariffs provide negative gains? Explain
2. Airbus and Boeing problem again. Suppose Boeing is more efficient at making airplanes
than Airbus. Starting from slide 33, Figure 10-9, let’s change the payoff matrix, so that if Boeing
and Airbus both produce, Boeing gets +5, instead of -5. And, if Boeing produces, and Airbus
does not produce, Boeing gets +125 instead of +100. Will there be a unique equilibrium in this
case?

Panel (a) illustrates a negative production externality, which means that the social marginal cost curve,
SMC, lies above the private marginal cost (supply) curve S. With free trade, the price falls from Pª to
PW and Home supply falls from Qo to S₁. As a result, the social cost of the externality is reduced by
area c, which measures a social gain that is additional to the private gains from trade, area b.

(part 3)
"Strategic" Use of High-Tech Export Subsidies
Payoff Matrix In Figure 10-9, we show a payoff matrix for Boeing and Airbus,
each of which has to decide whether to produce the new aircraft.

Payoff Matrix Between Two Firms The lower-left
number in each quadrant shows the profits of
Boeing, and the upper-right number shows the
profits of Airbus. Each firm must decide whether to
produce a new type of aircraft.A Nash equilibrium
occurs when each firm is making its best decision,
given the action of the other. For this pattern of
payoffs, there are two Nash equilibria, in the upper-
right and lower-left quadrants, where one firm
produces and the other does not.

Nash Equilibrium The idea of a Nash equilibrium is that each firm must make its own best
decision, taking as given each possible action of the rival firm. When each firm is acting that
way, the outcome of the game is a Nash equilibrium. The action of each player is the best
possible response to the action of the other player: 2 Nash equilibria - One in which Boeing
produces and Airbus does not; and one in which Airbus produces and Boeing does not.
