1 If my analysis does not use mixed strategies, simply interpret payments as ordinal representations of each player`s interests. But in the analogy of another convention of classical game theory, one might want to interpret the cardinal qualities of payments in such a way that they represent the attitude of players to risk in the context of judgments about their interests. Each theory of the team`s argument must explain which groups of individuals, under what circumstances, come to recognize themselves as teams. Bacharach sees this as a matter of group identification: a person takes care of team reflections on a particular group if and only if he identifies with that group (i.e. he considers himself part of the agency of that group). For Bacharach, group identification is ultimately a psychological phenomenon, not a matter of rational decision- The underlying idea is that the question of whether a particular act is rational is wrong, unless the unit of the agency has been specified: an action is rational for an agent to the extent that one can expect to achieve that agent`s objectives. So the question “Who am I?” (or `Who are we?` logically before the rational election. I will say more about Bacharach`s psychological theory of group identification. 2) Trade creates economies of scale for producers: for an increasing share of sectors that depend on innovation, global markets are creating economies of scale that allow them to recover high fixed costs for more customers. Not only does this lower prices, but it also allows for greater reinvestment in other innovation cycles.

Meanwhile, wages are higher in open economies than in closed economies, in part because exporting firms pay higher wages than firms that do not. In sub-Saharan Africa, for example, workers in exporting companies earn 34% more than the average wage. Similarly, American workers earn a 16% bonus in export-intensive industries, while Western European workers earn a bonus of between 10% and 20%.
