The Limited Liability Effect in Experimental Duopoly Markets
نویسندگان
چکیده
Brander and Lewis argue in a seminal paper (AER, 1986) that a Þrms debt-equity ratio should have important strategic effects on product market competition. We test their model in a duopoly experiment under both, Bertrand and Cournot competition. We Þnd that leverage has strategic effects, but those effects are much weaker than predicted by theory. SpeciÞcally, we Þnd for price competition a general tendency towards collusion, which has the same overall consequences but deviates from the subgame perfect equilibrium prediction. With quantity competition subjects choose much less debt than predicted by theory. It appears that subjects recognize the strategic effects of their own debt. However, they do not (want to) acknowledge possible strategic advantages of opponents debt. JELclassiÞcation numbers: L13, G33, D43.

متن کاملA game theory approach to the sawnwood and pulpwood markets in the north of Iran
Duopoly game theory is applied to the wood industrial markets (sawnwood and pulpwood markets) in the North of Iran. The Nash equilibrium and the dynamic properties of the system based on marginal adjustments are determined. The probability that the Nash equilibrium will be reached is almost zero. The dynamical properties of sawnwood and pulpwood prices derived via the duopoly game model are fou...

In financial markets, the main component of risk management is liquidity risk. Asset and Liability Management (ALM) strategy is concerned with managing all risks. Asset and liability management seeks to manage liquidity risk, which refers to both the liquidity of markets and which assets can be translated into cash. The liquidity is importantly affected by the management of banks’ balance sheet...
متن کاملAllowing for two production periods in the Cournot duopoly: Experimental evidence
In this study behavior in a Cournot duopoly with two production periods (the market clears only after the second period) is compared to behavior in a standard one-period Cournot duopoly. Theory predicts the endogenous emergence of a Stackelberg outcome in the two-period market. The results of the experiments, however, reveal that in both markets (roughly) symmetric outcomes emerge and that, aft...
متن کاملDOES COLLUSION WITHOUT COMMUNICATION EXIST? Some Experimental Evidence
Tacit cartels did not arise in experimental triopoly markets even with the help of detailed instructions to prospective cartel members on how to coordinate actions. In duopoly markets tacit cartels were successful, with winning bids and supporting “pass” bids increasing gradually. A simulated third bidder, entering with known probability, prevented the buildup of cartel prices in duopoly market...
