This paper studies repeated games with private monitoring where players make optimal decisions with respect to costly monitoring activities, just as they do with respect to stage-game actions. We consider the case where each player can observe other players' current-period actions accurately...

Theoretical work has suggested that contact between firms in different markets can facilitate tacit collusion. Empirical work on this link has been limited. We address the paucity of empirical evidence with a novel plant-level dataset for the cement industry during the Great Depression. We find...

The paper considers tacit collusion in markets which are not fully transparent on both sides. Consumers only detect prices with some probability before deciding which fi?rm to purchase from, and each fi?rm only detects the other fi?rm's price with some probability. Increasing transparency on the...

This paper investigates the effects on tacit collusion of increased market transparency on the consumer side as well as on the producer side of a market. Increasing market transparency on the consumer side, increases the benefits to a firm from undercutting the collusive price. It also decreases...

This paper considers the effect of monopoly-promoting export cartels on domestic production. It is argued that export cartels facilitate tacit collusion by monitoring defections more efficiently. This slackesn the incentive constraint of tacit collusion. Optimizing firms competing both in the...

Danish ready-mixed concrete is produced in regional oligopolies. Firms rely on price discrimination through secret discounts. The antitrust authority interprets this as lack of competition and has decided to activate its chief weapon against dormant competition: To make the market more...

We examine the novel concept for repeated noncooperative games with bounded rationality: \Nash-2" equilibrium, called also \threatening-proof prole" in [16, Iskakov M., Iskakov A., 2012b]. It is weaker than Nash equilibrium and equilibrium in secure strategies: a player takes into account not...

The arm's length principle states that the transfer price between two associated enterprises should be the price that would be paid for similar goods in similar circumstances by unrelated parties dealing at arm's length with each other. This paper examines the effect of the arm's length...

We model capacity-building investments in a homogeneous product duopoly facing uncertain demand growth. Capacity building is achieved through the addition of production units that are durable and lumpy and whose cost is irreversible. While building their capacity over time, firms compete à la...

This paper analyzes how the stability of the tacit cooperation within a fringe of sev- eral identical ?rms is a¤ected by the presence of a more e¢ cient ?rm which does not take part in their cooperative agreement. The model assumes that the ?rms of the fringe adopt ?stick and carrot?strategies...
