We experimentally investigate the effect of population viscosity (an increased probability to interact with others of one's type or group) on cooperation in a standard prisoner's dilemma environment. Subjects can repeatedly choose between two groups that differ in the defector gain in the...

This paper investigates what are the equilibrium distribution systems in a successive duopoly when retailers hold the power to choose the number of products they wish to market. Since they both can be multi-product sellers, the number of possible channel structures considered is larger than in...

This paper studies implementation of cooperative payoffs in finitely repeated games when players implement their strategies by finite automata of big sizes. Specifically, we analyze how much we have to depart from fully rational behavior to achieve the Folk Theorem payoffs, i.e., which are the...

In this paper we analyze incentives to invest in capacity prior to asequence of Cournot spot markets with varying demand. We compareequilibrium investment in the absence and in presence of the possibility to tradeon forward markets. We find that the possibility to trade forwards...

This paper examines retailers' strategic decisions about store brand introduction when each retailer can stock a limited number of brands. The different product line mix equilibria depend on demand parameters that measure the cross-effect across national and store brands and the cross-effect...

The main contribution of this paper is to present a new procedure to reach cooperation through pseudorandom schemes in the finitely repeated Prisoner's Dilemma game, when strategies are implemented by automata. The equilibrium path consists of a communication process followed by a coordinated...

This paper analyzes how leaming behaviour can modify the outcome of competition in an industry facing demand uncertainty. We consider a duopoly game where firms have imperfect information about market demand and leam through observing prices (Coumot competition) or sales (Bertrand) . The main...

This paper theoretically and experimentally explores a fixed price mechanism inwhich, if aggregate demand exceeds supply, bidders are proportionally rationed. Ifdemand is uncertain, in equilibrium bidders overstate their true demand in order toalleviate the effects of being rationed. This effect...

This paper deals with price competition among multiproduct firms. We consider a model with n firms and one representative buyer. Each firm produces a set of products that can be different or identical to the other firms' products. The buyer is characterized by her willingness to pay -in monetary...

We present laboratory experiments of five different multi-unit auction mechanisms. Two units of a homogeneous object were auctioned off among two bidders with flat demand for two units. We test whether expected demand reduction occurs in open and sealed-bid uniform-price auctions. Revenue...
