A robust feature of models of electoral competition between two opportunistic, purely office-motivated parties is that both parties become indistinguishable in equilibrium.

We show that a steeply increasing workload before a deadline is compatible with time-consistent preferences. The key departure from the literature is that we consider a stochastic environment where success of effort is not guaranteed.

We develop a model of rational bubbles based on the assumptions of unknown market liquidity and limited liability of traders. In a bubble, the price of an asset rises dynamically above its steady-state value, justified by rational expectations about future price developments. The larger the...

The paper provides a specification of belief systems for models of large economies with anonymity in which aggregate states depend only on cross-section distributions of types. For belief systems satisfying certain conditions of mutual absolute continuity, the paper gives a necessary and...

This article is concerned with the welfare properties of trade when the behavior of agents cannot be rationalized by preferences. I investigate this question in an environment of matching allocation problems. There are two reasons for doing so: firstly, the finiteness of such problems entails...

The modern state has monopolized the legitimate use of force. This concept is twofold. First, the state is empowered with enforcement rights; second, the rights of the individuals are (partly) restricted. In a simple model of property rights with appropriation and defense activity, we show that...

Disclosure of information triggers immediate price movements, but it mitigates price movements at a later date, when the information would otherwise have become public. Consequently, disclosure shifts risk from later cohorts of investors to earlier cohorts. Hence, disclosure policy can be...
