When the market is modelled as a standard signalling game, inefficient outcomes arise due to the arbitrariness of off-the-equilibrium path beliefs. Such inefficient outcomes are shown not to arise in a novel game that combines signalling and competitive screening. In this game, the informed party makes an initial offer to all uninformed parties, but the uninformed parties are allowed to make counter-offers after accepting the initial offer. The initial offer serves as a barrier to potential cream-skimming deviations, and hence, equilibrium is shown to generically exist. As such, the paper also contributes to the literature that focuses on laying strategic foundations for efficient competition in competitive screening markets."

When productivity is not sufficiently dispersed, safe-type entrepreneurs face borrowing constraints and might under- or over-invest relative to the social optimum. Reversals in the order of productivities cause large fluctuations in investment and output. Better economic conditions, expansionary monetary policy and decreases in default probabilities do not always boost investment and welfare. When the model is extended to allow for endogenous occupational choice, would-be safe-type entrepreneurs might inefficiently select to become workers. In a numerical example, it is shown that (a) the interest rate elasticity of investment is considerably higher during booms than during busts, and (b) a decrease in interest rates during busts has an effect on both the intensive and extensive margin."

"fr" => "This article studies general economies with adverse selection in which symmetric companies supply (potentially multiple) plans to privately informed consumers and compete in terms of price schedules. I show that a basic price cap regulation, in which the price caps are endogenously determined by companies, discourages risk selection over efficient allocations, and therefore, equilibrium exists in every economy. Moreover, I demonstrate that in generalisations of Rothschild and Stiglitz (1976) and Wilson (1977) economies, companies earn zero profits in equilibrium, and every equilibrium allocation is efficient."

The use of the service generates valuable data, but data monetization entails a privacy cost for users. A trade-off emerges between under-processing and over-monetization of data. We show that both the firm and users prefer the users (the firm) to own the rights for low (high) values of data. We further discuss the robustness of our results when allowing more possible contracts for the data owner and show that the main trade-off is robust to these extensions."
