We study sequential bargaining between two unions and a single firm. Parties bargain bilaterally and efficiently (over wage and employment). The unions' workforces can be substitutable ("tariff competition") or complementary ("tariff plurality" or "craft unionism"). If unions are substitutable,...

We consider a monopolistic supplier's optimal choice of wholesale tariffs when downstream firms are privately informed about their retail costs. Under discriminatory pricing, downstream firms that differ in their ex ante distribution of retail costs are offered different tariffs. Under uniform...

This paper studies the impact of a dominant firm's conditional discounts on competitors' learning-by-doing. In a vertical context where a dominant upstream supplier and a competitive fringe sell their products to a single downstream firm, we analyze whether the dominant supplier prefers to off...

I model the optimal semi-collusive strategy of firms using forward contracts in volatile markets. It has been shown that forward contracts can be used to stabilize a collusive agreement under deterministic (Liski and Montero, 2006) as well as under stochastic market conditions (Aichele, 2012)....

We analyze firms incentives to bundle and tie in the telecommunications industry. As a first step, we develop a discrete-choice demand model where firms sell products that may combine several services in bundles, and consumers choose assortments of different types of products available from...

When sellers join a platform to sell their products, the platform operator may restrict their strategic decisions. In fact, several platform operators impose most-favored treatment or no-discrimination rules (NDRs), asking sellers not to offer better sales conditions elsewhere. In this paper, I...

Retailer bargaining power is an important aspect of many international antitrust investigations. Size and market share analysis are often the cornerstones of bargaining power identification. However, other factors, like consumer behavior, i.e. "one-stop shopping", can heavily affect the...

We study a sequential screening problem where the agent produces an object consisting of multiple items and has a multidimensional type that he learns over time. Depending on the strength of complementarity/substitutability of the items, the optimal allocation features a different pattern of...

With the help of lab experiments we study the impact of discharging insolvent debtors of their residual debt. We investigate the impact of different participation rules and the impact of different types of lenders. We find that higher participation rates encourage risk taking behaviour of...

We analyze optimal labor contracts when the worker is inequity averse towards the employer. Welfare is maximized for an equal sharing rule of surplus between the worker and the firm. That is, profit sharing is optimal even if effort is contractible. If the firm can make a take-it-or leave-it...
