This paper introduces an informal model of behavior of Politicians and Social Leaders in their mutual relations in the context of influencing the beliefs of voters. Facing uncertainty about Politicians voters turn to Social Leaders as information short-cuts. Leaders include NGOs, the media and...

In this paper we analyze the problem of whether and/or when to replace a leader (agent) when no monetary rewards are available, and it is the leader's competence rather than effort that is being evaluated. The only decisions that the leader takes over time are whether to undertake risky but...

his paper examines how violence in the Second Intifada influences Palestinian public opinion. Using micro data from a series of opinion polls linked to data on fatalities, we find that Israeli violence against Palestinians leads them to support more radical factions and more radical attitudes...

We study the equilibrium properties of an overlapping-generation economy where agents choose where to locate and how much housing to own, and city residents vote on the number of new building permits every period. Undersupply of housing persists in equilibrium under conditions we characterize....

Evidence suggests that banks tend to lend a lot during booms, and very little during recessions. We propose a simple explanation for this phenomenon. We show that, instead of dampening productivity shocks, the banking sector tends to exacerbate them, leading to excessive fluctuations of credit,...

Our paper examines the effect of recent regulatory proposals mandating the deferral of bonus payments and claw-back clauses for compensation contracts in the financial sector. We study a multi-task setting in which a bank employee, the agent, privately chooses (deal or customer) acquisition...

We provide a rationale for imposing counter-cyclical capital ratios on banks. In our simple model, bankers cannot pledge the entire future revenues to investors, which limits borrowing in good and bad times. Complete markets do not sufficiently stabilize credit fluctuations, as banks allocate...

We consider the optimal design of mortgage-backed securities (MBS) in a dynamic setting in which a mortgage underwriter with limited liability can engage in costly hidden effort to screen borrowers and can sell loans to investors. We show that (i) the timing of payments to the underwriter is the...

This paper offers evidence on the design of subprime mortgages as bridge-financing products. We show that the viability of subprime mortgages was uniquely predicated on the appreciation of house prices over short horizons. High rates of early prepayments on subprime mortgages suggest the use of...
