Furthermore, in an era of aging population, they constitute an obstacle to reaching the welfare state equilibrium.
The paper investigates firms' behavior and outcomes (levels of cost-reducing R&D, output, profit and welfare in equilibrium) in a differentiated duopoly with process innovation.
We show the optimality of such a voting procedure by arguing that it is first best, that is, it maximizes welfare when equilibrium constraints are ignored, and by showing that individual incentives and social welfare are sufficiently aligned to make a first best procedure incentive compatible.
Third, partial equilibrium welfare calculations are extremely poor predictors of their general equilibrium counterparts.
So, the economic efficiency or social welfare of Nash equilibrium is 2.77 times as much as the real market.
Therefore, the efficiency or social welfare of Nash equilibrium is 3.6 times as much as the real market.
We show that the mechanism's performance improves with the number of agents that can coordinate their bids, and reaches half of the optimum welfare at strong equilibrium.
In addition, there are 184 allowed plants for the second case (plants should offer their maximum power with different prices) and the efficiency or social welfare of Nash equilibrium is 3.6 times as much as the real market.
From (4) and Proposition 3, it follows that, in equilibrium, social welfare is: Social welfare does not depend on d when 1 ≥ 3dc.
