Public Policy with Endogenous Preferences

Public policy may influence norms and preferences. By altering the payoffs associated with different preferences, public policy may influence the distribution of these preferences in the population. Such interdependence between policy and preferences may limit (or enhance) the effectiveness of different policies. We demonstrate this idea with a simple model of subsidizing contributions to a public good. While the short‐run effect of such a subsidy will be an increase in the overall contribution, the subsidy triggers an endogenous preference change that results in a lower level of contribution to the public good, despite the explicit monetary incentives to raise that level.     

Sovereign Debt without Default Penalties

We develop a theory of sovereign borrowing where default penalties are not implementable. We show that when debt is held by both domestic and foreign agents, the median voter might have an interest in serving it. Our theory has important practical implications regarding (a) the role of financial intermediaries in sovereign lending, (b) the effect of capital flows on price volatility including the possible overvaluation of debt to the point that the median voter is priced out of the market, and (c) debt restructuring where creditors are highly dispersed.
