El colchón de capital anticíclico (CCyB, por sus siglas en inglés) se ha convertido en una herramienta macroprudencial muy importante para reforzar la resistencia de los bancos debido a su diseño anticíclico y a su posibilidad de ser liberado. Sin embargo, la evidencia sobre su impacto en...

El artículo propone un marco para evaluar el impacto de los colchones de capital a nivel de todo el sistema y a nivel bancario. La evaluación se basa en un modelo FAVAR (Factor-Augmented Vector Autoregression) que relaciona los ajustes bancarios individuales con la dinámica macroeconómica....

In the macroeconomic literature, the implications of a context with household heterogeneity and incomplete financial markets have been mostly studied under the assumption that households own the physical capital and undertake the intertemporal investment decision. Further, firms rent capital and...

Many recent papers in macroeconomics have studied the implications of models with household heterogeneity and incomplete financial markets under the assumption that households own the stock of physical capital and undertake the intertemporal investment decisions. In these models, production...

Recent developments in intertemporal asset pricing theory focus on two sets of fundamental determinants of asset returns. Models with complete markets emphasize aggregate variables such as per capita consumption. Such models have not performed well empirically. Models with incomplete markets...

This dissertation considers the pricing and hedging of contingent claims in a generalsemimartingale market. Initially the focus is on a complete market, where it ispossible to price uniquely and hedge perfectly. In this context the two fundamentaltheorems of asset pricing are explored. The...

We document widespread violations of stochastic dominance by one-month S&P 500 index call options market over 1986-2006. These violations imply that a trader can improve her expected utility by engaging in a zero-net-cost trade. We allow the market to be incomplete and also imperfect by...

An economy faces an unknown individual risk, such as the health effects of a recently discovered environmental hazard. Opinions may be widely different about the distribution of risks across the population. We study financial markets that suffice to reach efficient allocations in this situation....

The introduction of financial assets to hedge individual risk can lead to the risk of default, which is a collective risk. The...
