Book Description
The thesis analyzes the effect that the sample size, the asymmetry in the distribution of returns and the leverage in their volatility have on the estimation and forecasting of market risk in financial assets. The goal is to compare the performance of a variety of models for the estimation and forecasting of Value at Risk (VaR) and Expected Shortfall (ES) for a set of assets of different nature: market indexes, individual stocks, bonds, exchange rates, and commodities. The three chapters of the thesis address issues of greatest interest for the measurement of risk in financial institutions and, therefore, for the supervision of risks in the financial system. They deal with technical issues related to the implementation of the Basel Committee's guidelines on some aspects of which very little is known in the academic world and in the specialized financial sector. In the first chapter, a numerical correction is proposed on the values usually estimatedwhen there is little statistical information, either because it is a financial asset (bond, investment fund...) recently created or issued, or because the nature or the structure of the asset or portfolio have recently changed. The second chapter analyzes the relevance of different aspects of risk modeling. The third and last chapter provides a characterization of the preferable methodology to comply with Basel requirements related to the backtesting of the Expected Shortfall.

Book Description
Do financial derivatives enhance or impede innovation? We aim to answer this question by examining the relationship between equity options markets and standard measures of firm innovation. Our baseline results show that firms with more options trading activity generate more patents and patent citations per dollar of R&D invested. We then investigate how more active options markets affect firms' innovation strategy. Our results suggest that firms with greater trading activity pursue a more creative, diverse and risky innovation strategy. We discuss potential underlying mechanisms and show that options appear to mitigate managerial career concerns that would induce managers to take actions that boost short-term performance measures. Finally, using several econometric specifications that try to account for the potential endogeneity of options trading, we argue that the positive effect of options trading on firm innovation is causal.

Book Description
Este libro ha sido concebido con la vocación de servir como material didáctico. Para ello, se analiza de manera pedagógica, el complejo entorno en que se desenvuelven las entidades financieras, y las herramientas que les puede aportar el marketing para sobrevivir en un mercado maduro y sujeto a innumerables retos. Los autores exponen de manera sencilla y comprensible tanto las estrategias como las tácticas de marketing que requieren las empresas del sector financiero para ser competitivas. El lector encontrará en estas páginas ejemplos e ilustraciones de bancos de países de distintos continentes, y podrá conocer la evolución que ha experimentado el marketing en las entidades financieras, pasando de un enfoque de relaciones públicas, a la promoción de ventas y al uso de la publicidad. En esta evolución, al igual que ha sucedido en otros sectores, la crisis financiera mundial ha provocado que los bancos hayan tomado conciencia de la utilidad del marketing para colocar al cliente en el centro de su modelo de negocio. Como consecuencia, este libro nace con el ánimo de llenar el vacío relativo al conocimiento del uso efectivo del marketing en este sector. Y por ello, en esta obra se expone el proceso estratégico y operativo que deben utilizar las instituciones financieras para satisfacer las necesidades de sus segmentos objetivos. En su interior se desarrollan también, de manera armónica, los conceptos prácticos y empíricos que pueden ser usados tanto por estudiantes de grado y de postgrado, como por profesionales interesados en conocer de qué forma utilizar el marketing de adquisición y de retención en el sector financiero. Este conocimiento es esencial para instituciones que enfrentan condiciones de mercado de creciente complejidad y competitividad. En donde la aparición de nuevos actores (principalmente empresas tecnológicas), ha comenzado a amenazar líneas de negocio hasta ahora exclusivas de los bancos tradicionales.

Book Description
This book adds to the resolution of two problems in finance and economics: i) what is macro-financial uncertainty? : How to measure it? How is it different from risk? How important is it for the financial markets? And ii) what sort of asymmetries underlie financial risk and uncertainty propagation across the global financial markets? That is, how risk and uncertainty change according to factors such as market states or market participants. In Chapter 2, which is entitled “Momentum Uncertainties”, the relationship between macroeconomic uncertainty and the abnormal returns of a momentum trading strategy in the stock market is studies. We show that high levels of uncertainty in the economy impact negatively and significantly the returns of a portfolio of stocks that consist of buying past winners and selling past losers. High uncertainty reduces below zero the abnormal returns of momentum, extinguishes the Sharpe ratio of the momentum strategy, while increases the probability of momentum crashes both by increasing the skewness and the kurtosis of the momentum return distribution. Uncertainty acts as an economic regime that underlies abrupt changes over time of the returns generated by momentum strategies. In Chapter 3, “Measuring Uncertainty in the Stock Market”, a new index for measuring stock market uncertainty on a daily basis is proposed. The index considers the inherent differentiation between uncertainty and the common variations between the series. The second contribution of chapter 3 is to show how this financial uncertainty index can also serve as an indicator of macroeconomic uncertainty. Finally, the dynamic relationship between uncertainty and the series of consumption, interest rates, production and stock market prices, among others, is analized. In chapter 4: “Uncertainty, Systemic Shocks and the Global Banking Sector: Has the Crisis Modified their Relationship?” we explore the stability of systemic risk and uncertainty propagation among financial institutions in the global economy, and show that it has remained stable over the last decade. Additionally, a new simple tool for measuring the resilience of financial institutions to these systemic shocks is provided. We examine the characteristics and stability of systemic risk and uncertainty, in relation to the dynamics of the banking sector stock returns. This sort of evidence is supportive of past claims, made in the field of macroeconomics, which hold that during the global financial crisis the financial system may have faced stronger versions of traditional shocks rather than a new type of shock. In chapter 5, “Currency downside risk, liquidity, and financial stability”, downside risk propagation across global currency markets and the ways in which it is related to liquidity is analyzed. Two primary contributions to the literature follow. First, tail-spillovers between currencies in the global FX market are estimated. This index is easy to build and does not require intraday data, which constitutes an important advantage. Second, we show that turnover is related to risk spillovers in global currency markets. Chapter 6 is entitled “Spillovers from the United States to Latin American and G7 Stock Markets: A VAR-Quantile Analysis”. This chapter contributes to the studies of contagion, market integration and cross-border spillovers during both regular and crisis episodes by carrying out a multivariate quantile analysis. It focuses on Latin American stock markets, which have been characterized by a highly positive dynamic in recent decades, in terms of market capitalization and liquidity ratios, after a far-reaching process of market liberalization and reforms to pension funds across the continent during the 80s and 90s. We document smaller dependences between the LA markets and the US market than those between the US and the developed economies, especially in the highest and lowest quantiles.

Book Description
La relevancia de los objetivos de esta investigación viene potenciada por la actual crisis financiera, que ha provocado en muchos ámbitos la revisión de elementos presentes en las estructuras de distintos sistemas económicos, jurídicos y empresariales. Asimismo, ha puesto en evidencia la necesidad de analizar, interpretar y renovar las condiciones en las que se aborda la toma de decisiones en diferentes problemas de impacto y relevancia indiscutibles en las economías actuales. La investigación realizada, que en este libro se recoge, desarrolla dos modelos de análisis en el riesgo de crédito, uno cualitativo y otro cuantitativo, que sirven de apoyo a las decisiones conducentes a la concesión de créditos a empresas no cotizadas en Bolsa y permite disminuir los errores inherentes a dicha decisión. Para la elaboración de dichos modelos se ha partido del estudio de los elementos que intervienen en la decisión de conceder créditos por parte de las entidades financieras, así como del análisis y discusión de los estudios actuales que versan sobre la estimación de las situaciones de fracaso empresarial. El resultado obtenido es por una parte, un modelo de probabilidad de impago que complementa el análisis y las predicciones de los modelos existentes en la actualidad al introducir nuevas variables independientes , y por otro lado, un nuevo y novedoso modelo que determina el volumen de deuda que se podría conceder sin riesgo en el corto plazo, basado en flujos de caja y que incorpora como elemento corrector la evolución de determinadas variables que se consideran en esta investigación como variables críticas en la actualidad económica de las empresas.

Book Description
House price bubbles, and their aftermath, have become a focus of macro-economic policy concern in most developed countries. This book elucidates the two-way relationship between house-price fluctuations and economic fundamentals. Housing has many features which make it distinct from other assets, like equity. Real estate is not only an asset but also a durable consumption good for households, providing shelter and other housing services. As a result, a house is often the largest and most important asset of households and therefore accounts for a major share of household wealth. Similarly a large share of bank assets is tied to housing values. House price fluctuations may, therefore, have a major effect on economic activity and the soundness of the financial system. Following an introductory chapter, the book is structured into three parts. The first demonstrates the importance of house prices as determinants or indicators of inflation and economic activity. The second focuses on the inter-relationships between bank credit extension and housing prices, and how bubbles can lead to financial crises. The third discusses resultant public policy issues, such as whether, and how, to include housing prices in a general inflation index, and how to restrain the housing/bank credit cycle.
