Abstract: We analyze a monopolist’s pricing and product reliability problem when consumers are entitled to product replacement but have heterogeneous cost of exercising this right, and we assess the implications of a decrease in consumers’ claiming cost on reliability, pro?t, and welfare. We...

One of the most salient issues faced by platforms like newspapers and credit card issuers is that users are heterogeneous in the value they bring to other users or to the platform. We develop a model with multi-dimensional heterogeneity where a monopoly platform chooses (price or non-price)...

Search engines face an interesting tradeoff in choosing the way to display their results. While providing high quality unpaid, or “left side” results attracts users, doing so can also cannibalize the revenue that comes from paid ads on the “right side”. This paper examines this tradeoff,...

This Paper uses a unique representative firm level data set to analyse the effect of domestic and international competitive pressure and ownership changes in three emerging economies, Bulgaria Poland and Romania. Our main findings can be summarized as follows: Domestic competitive pressure,...

We study a multidimensional screening problem with minimal restrictions on valuations. Our ?-relaxation of the constraints excludes bunching and cycles in the graph of active incentive-compatibility constraints. Therefore, the Lagrange multipliers do exist and enable us in characterizing...

We study the screening or nonlinear pricing for discrete consumer types when the single-crossing condition need not hold. A method is developed to reveal social eff±ciency or distortion of equilibria from market observations. The two known indicators of effciency, namely absence of almost-envy...

We study discrete-type screening without Spence-Mirrlees condition. Under non-separable and non-concave cost, all packages can be distorted in equilibrium, even when only the participation constraints are active. This and other paradoxical effects, shown by examples, are caused by some kind of...

It is shown that supplementing any usage-based pricing with a flatt-fee scheme is profit improving when the savings from transactions costs and from deadweight loss by using flat fee exceed the additional production costs. We use a most general model, without many traditionally used assumptions...
