A modified morphology was introduced for poly(3-hexylthiophene):phenyl-C71-butyric acid methyl ester (P3HT:PC71BM) bulk heterojunction (BHJ) solar cells by thermal and solvent annealing treatments in the presence of hydrophilic-hydrophobic block copolymers. Power conversion efficiency (PCE) plummet was prohibited during both thermal and solvent treatments for all BHJ devices modified wit...

in iran’s system of tripartite collective bargaining, does the wage-policy maker consistently react optimally to the best move made by the exchange rate-policy maker (nash-rule) or only to the state of economy (non-nash rule)?. this paper not only investigates the nature of the political game (nash rule against non-nash rule) but also estimates some structural parameters by using 2sls method an...

Poly(3-hexylthiophene) (P3HT) and [6,6]-phenyl-C71 butyric acid methyl ester (PCBM) polymer solar cell is studied by using GPVDM simulations experiments. The research focuses on the effects of active layer thickness structures as bulk heterojunction (BHJ) (ITO/P3HT:PCBM/Al) compared to a bilayer structure (ITO/P3HT/PCBM/Al). optimal 200 nm obtained in simulation for BHJ structure. results also ...

The Myerson’s models on partial cooperation have been studied extensively [SIAM J. Discrete Math. 5 (1992) 305; Math. Methods Operations Res. 2 (1977) 225; Int. J. Game Theory 19 (1980) 421; 20 (1992) 255]. In [Game Econ. Behav. 26 (1999) 565], Hamiache proposes a new solution concept for communication situations. In this work, we analyze this value making some deficiencies clear and generalize...

We propose a generalization of simple games to situations with coalitional externalities. The main novelty of our generalization is a monotonicity property that we define for games in partition function form. This property allows us to properly speak about minimal winning embedded coalitions. We propose and characterize two power indices based on these kind of coalitions. We provide methods bas...

In this paper, we consider a local public goods environment. The agents are faced with the task of providing local public goods that will benefit some or all of them. We propose a bidding mechanism whereby agents bid for the right to decide upon the organization of the economic activity. The subgame perfect equilibria of the mechanism generate efficient outcomes. We also show how to adapt the m...

This paper provides a framework for implementing and comparing several solution concepts for transferable utility cooperative games. We construct bidding mechanisms where players bid for the role of the proposer. The mechanisms differ in the power awarded to the proposer. The Shapley, consensus and equal surplus values are implemented in subgame perfect equilibrium outcomes as power shifts away...

This paper solves merger formation problem in Cournot oligopolies by a cooperative and computational approach. In three-firm linear oligopolies, monopoly will be formed (or be stable) if its merging cost is sufficiently low and cost differentials are sufficiently large. When monopoly is unprofitable due to high merging costs, a profitable two-member merger will be formed if its efficient member...
