Is the seniority structure of sovereign debt neutral for a government's decision between defaulting and raising surpluses? In this paper, we address this question using a model of debt crises where a discretionary government endogenously chooses distortionary taxation and whether to apply an optimal haircut to bondholders. We show that when the size of senior tranches is small, a version of the Modigliani-Miller theorem holds: tranching just redistributes government revenues from junior to senior bondholders, while taxes and government borrowing costs remain unchanged. However, as senior tranches become sufficiently large, default costs on senior debt transpire into a stronger commitment to repay not only the senior tranche, but also the junior one. We show that there is a lower threshold for senior bonds above which tranching can eliminate default on both junior and senior debt, and an upper threshold beyond which the government defaults also on senior debt.

This paper develops a model to interpret the 2012 eurozone crisis and the ECB’s policy response. In the model, bank lending is distorted by debt overhang, banks hold sovereign bonds, and the government guarantees the bailout of bank creditors. A self-fulfilling pessimistic view of the economy can trigger a banking and sovereign crisis: with pessimistic economic expectations, the value of sovereign bonds declines, the bank risk of default rises, and the debt overhang distortion worsens; this leads to a contraction in bank lending and to a decline in economic activity, which confi rms the initial pessimistic expectations. A commitment by the central bank to purchase the sovereign bonds at pre-crisis market spreads manages to eliminate the crisis equilibrium.

This paper explores the determinants of 10-year sovereign bond spreads over the German Bund benchmark in the Euro Zone from 2000 to 2013, relying on cross-country quarterly data panel analysis. The paper focal point is the role of contagion and euro break-up risks in widening the sovereign bond yield differentials among EU member countries. Using a novel synthetic index capable of monitoring the sustainability of currency unions, the paper finds that market expectations of a euro’s break up and contagion from Greece were fundamental drivers of sovereign risk premia in peripheral countries.

This paper considers a simple model of self-fulfilling expectations that leads to a multiple equilibrium of gender gaps in wages and participation rates. Rather than resorting to moral hazard problems related to unobservable effort, like in most of the related literature, our model fully relies on statistical discrimination. If firms believe that women will quit their jobs more often than equally productive men when shocks affecting household chores take place, our model predicts that this belief will increase the wage gap in favour of men which, in turn, will increase the female share of housework and exacerbate lower female participation in the labour market. Hence, both effects lead to a gendered equilibrium with large gaps, even though an ungendered equilibrium with no gaps is feasible. We examine the effects of gender-based and gender-neutral subsidies and find that the latter are more effective in removing the gendered equilibrium. Empirical analysis based on a time use survey for Spain is provided to test most of the implications of the model. Banco de Santander

This paper examines the ability of a policy maker to control equilibrium outcomes in a global coordination game; applications include currency attacks, bank runs, and debt crises. A unique equilibrium is known to survive when the policy is exogenously fixed. We show that, by conveying information, endogenous policy re-introduces multiple equilibria. Multiplicity obtains even in environments where the policy is observed with idiosyncratic noise. It is sustained by the agents coordinating on different interpretations of, and different reactions to, the same policy choices. The policy maker is thus trapped into a position where both the optimal policy and the coordination outcome are dictated by self-fulfilling market expectations.
