Recent economic developments have shown the importance of spillover and contagion effects in financial markets. Such effects are not limited to relations between the levels of financial variables but also impact on their volatility. I investigate Granger causality in conditional mean and...

We consider an economy where individuals face uninsurable risks to their human capital accumulation, and study the problem of determining the optimal level of linear taxes on capital and labor income together with the optimal path of the debt level. We show both analytically and numerically that...

Spillover and contagion effects have gained significant interest in the recent years of financial crisis. Attention has not only been directed to relations between returns of financial variables, but to spillovers in risk as well. I use the family of Constant Conditional Correlation GARCH models...

We study a general equilibrium model in which firms choose their capital structure optimally, trading off the tax advantages of debt against the risk of costly default. The costs of default are endogenous: bankrupt firms are forced to liquidate their assets, resulting in a fire sale if there is...

In markets where transactions are governed by contractual incompleteness, revealed intentions to evade taxes may affect market performance. We experimentally examine the impact of tax evasion attempts on the performance of credence goods markets, where contractual incompleteness results from...

Credence goods, such as car repairs or medical services, are characterized by severe informational asymmetries between sellers and consumers, leading to fraud in the form of provision of insufficient service (undertreatment), provision of unnecessary service (overtreatment) and charging too much...

This paper refers to the ranking of densities that describe the distribution of an attribute in a given set of populations. The key elements of the problem are: (i) The distributions refer to ordered categorical data (e.g. health statuses, educational achievements, prestige positions,...

The contribution of this paper is twofold. First, we provide empirical evidence on the existence of a risk-taking channel in the US economy. By identifying a Bayesian VAR through sign restrictions, we find that an expansionary monetary policy shock causes a persistent increase in proxies for...

We develop a two-period model where banks invest in reserves and loans, and are subject to aggregate liquidity shocks. When banks face a a shortage of liquidity, they can sell loans on the interbank market. Two types of equilibria emerge. In the no default equilibrium, banks keep enough reserves...

Socio-economic performance differs not only across countries but within countries too and can persist even after religion, language, and formal institutions are long shared. One interpretation of these disparities is that successful regions are characterized by higher levels of trust, and, more...
