We examine the conditions required for the existence of private credit bureaus, their ownership and coverage. Our model implies that bank consortia will most likely be preferred by banks, but that they will lead to restricted coverage. Independent credit bureaus have higher coverage, but they...

This paper shows that a stock market is evolutionary stable if andonly if stocks are evaluated by expected relative dividends. Any othermarket can be invaded by portfolio rules that will gain market wealthand hence change the valuation. In the model the valuation of assetsis given by the wealth...

The paper seeks to lay out a stock-flow-based theoretical framework that provides a foundation for a general theory of pricing. Contemporary marginalist economics is usually based on the assumption that prices are set in line with the value placed on goods by consumers. It does not take into...

Various approaches used in Agent-based Computational Economics (ACE) to model endogenously determined interactions between agents are discussed. This concerns models in which agents not only (learn how to) play some (market or other) game, but also (learn to) decide with whom to do that (or not).

This paper aims to characterise a dynamic, incentive-compatible contract for the provision of health services, allowing for both moral hazard and adverse selection. Patients' severity changes over time following a stochastic process and is private information of the provider. We characterise the...

We study the effects of granting an exit option that enables the private party to early terminate a PPP project if it turns out to be loss-making. In a continuous time setting with hidden information about stochastic operating profits, we show that a revenue-maximizing government can optimally...

We study the effects of granting an exit option that enables the private party to early terminate a PPP project if it turns out to be financially loss-making. In a continuous-time setting with hidden information about operating profits, we show that an exit option, acting as a risk-sharing...

In a continuous-time setting, we study the design of a dynamic contract between a government and a private entity, wherein the latter commits to pay the government in return for the exclusive right to sell a service by operating a public facility. Private revenues are modelled as depending on...

The standard solution to adverse selection is the separating equilibrium introduced by Rothschild and Stiglitz. Usually, the Rothschild-Stiglitz argument is developed in a model that allows for two states of the world only. In this paper adverse selection is dis-cussed for continuous loss...

Many studies have found a gap between willingness-to-pay and willingness-to-accept that is inconsistent with standard theory. There is also evidence that the gap is eroded by experience gained in the laboratory and naturally occurring markets. This paper argues that the gap and the effects of...
