In a model with both issues of sovereign debtor moral hazard and creditor coordination under incomplete information, we show that the resulting conflict between ex ante and interim efficiency limits the welfare impact of strengthening CACs. Conditional on default, we show that an interim...

We study banking with ex ante moral hazard. Resolving the misalignment of the incentives between banks and depositors requires early liquidation with positive probability : efficient risk-sharing between depositors is no longer implementable. In a closed region with a single bank, we show that...

We study decision problems where (a) preference parameters are defined to include psychological/moral considerations and (b) there is a feedback effect from chosen actions to preference parameters. In a standard decision problem the chosen action is required to be optimal when the feedback...

This paper studies how intra-elite confict results in transition to democracy, characterized as both franchise extension to, and lowering the individual cost of collective political action for, an initially disorganized non-elite. Two risk averse elites compete for the appropriation of a unit of...

This paper shows the robust non existence of competitive equilibria even in a simple three period representative agent economy with dynamically inconsistent preferences. We distinguish between a sophisticated and naive representative agent. Even when underlying preferences are monotone and...

In this paper, we investigate the problem of the strategic foundation of the Cournot-Walras equilibrium approach. To this end, we respecify a'la Cournot-Walras the mixed version of a model of simultaneous, noncooperative exchange, originally proposed by Lloyd S.Shapley. We show, through an...

In a model of majority voting with common values and costly but voluntary participation, we show that in the vicinity of equilibrium, it is always Pareto-improving for more agents, on the average, to vote. This demonstrates that the negative voting externality identified by Borgers(2001) in the...

Is the result that equilibrium trading outcomes are efficient in markets without frictions robust to a scenario where agents' beliefs and plans aren't already aligned at their equilibrium values? In this paper, starting from a situation where agents' beliefs and plans aren't already aligned at...

In this paper we discuss global climate change mitigation that builds on existing unilateral actions to deliver ever deepening emission cuts over time. A wide array of unilateral environmental measures have been documented. We discuss the rationale for such measures and argue that unilateral...

We provide a model of the links between commercialisation and technological progress, which is consistent with the historical evidence and places market relations at the heart of the industrial revolution. First, commercialisation raised wages as a growing reliance on impersonal labour market...
