The recent euro area crisis shows some similarities with the fixed exchange rate crisis that affected the European Monetary System in 1992–93. I argue that the theoretical framework to be used in order to analyze them should also be similar. As a matter of fact, in both cases, the point of view of the government (that compares costs and benefits of its action) should be considered together with the point of view of speculators, who look at the state of the economic fundamentals in order to decide whether to launch an attack or not. This allows to represent and to interpret, among other things, both the initial “honeymoon” years of EMU and the recent euro area crisis.

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.

Countries with higher implicit taxes on continued work are associated with lower labor force participation rates of the elderly. This paper constructs a politicoeconomic model that accounts for this feature based on multiple, self-fulfilling expectations of agents. In this model, agents are identical at birth and can become skilled (or remain unskilled) through educational investment. When agents hold expectations of larger social security benefits, it provides a disincentive to engage in educational investment, thereby resulting in an unskilled majority. In turn, this unskilled majority supports larger social security benefits, which induces the retirement of the elderly and thus results in a lower labor force participation rate. The opposite applies when agents have expectations of smaller social security benefits in their old age.

We investigate Matsuyama's (Econometrica, 72, pp. 853-84, 2004) model modi- fied only to include endogenous and forward looking labor supply decision. Young agents supply one unit of labor endowment elastically to a competitive labor market. While, old agents of ex-ante identical individuals are divided in equi- librium into depositors and entrepreneurs. Depositors lend funds in the form of interest bearing loans, while entrepreneurs borrow funds in the competitive credit market. We emphasize the interaction between credit and labor markets and show the possibility of occurrence of multiple steady states, local and global indeterminacy, and endogenous fluctuations. When young agents become optimistic about the future deposit rate then they decide to work harder and invest more. Countercyclical borrowing constraint will help agents to fulfill their initial optimistic expectations, because the next period credit volume and deposit rate can increase simultaneously. By conducting global bifurcation analysis, we show that credit cycles can occur through a self- fulfilling expectation mechanism. History-versus-expectations considerations can exist and escape from underdevelopment as well as fall into poverty can to be a self-fulfilling prophecy.

This paper analyses the dynamic implications of an asset-pricing model with incomplete participation due to entry costs. It is shown that heterogeneity in entry costs can lead to the existence of multiple stochastic sunspot equilibria, whereby the number of agents in the market and asset prices fluctuate endogeneously over time in the absence of fundamental uncertainty. Such asset-price fluctuations occur despite the uniqueness of the deterministic equilibrium, and thus bear no link to the usual notion of steady-state indeterminacy. In addition to excess volatility, the equilibria exhibit predictable and conditionally heteroskedastic returns.

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

We show that dependence on foreign energy can increase economic instability by raising the likelihood of equilibrium indeterminacy, hence making fluctuations driven by self-fulfilling expectations easier to occur. This is demonstrated in a standard neoclassical growth model. Calibration exercises, based on the estimated share of imported energy in production for several countries, show that the degree of reliance on foreign energy for many countries can easily make an otherwise determinate and stable economy indeterminate and unstable.

Foreign Trade and Equilibrium Indeterminacy Abstract: We show that dependence of production on foreign inputs (or non-producible natural resources) can significantly increase the likelihood of indeterminacy. Payment of imported foreign factors of production may act as a semi-fixed cost, amplifying production externalities and returns to scale, making selffulfilling expectations driven busyness cycles easier to arise. This is demonstrated using a standard neoclassical growth model. Calibration exercise shows that the required increasing returns to scale can be reduced by as much as 64% based on estimated share of foreign inputs in production for OECD countries.

It is often suggested that "European economic and monetary integration is important because people think it is". This paper is an exploratory attempt to formalize this idea. As the basis for our investigation, we rely on recent analysis by Krugman (1989) and Matsuyama (1989), which addresses the process of equilibrium determination in a stylized economy in which more than one equilibrium is possible. As an additional dimension, we also address potential implications for unemployment using the unemployment hysteresis model of Blanchard and Summers (1986).
