The purpose of this paper is to apply the results of Brandolini D. – Colucci S. “Backtesting Value-at-Risk: A comparison between Filtered Bootstrap and Historical Simulation” in order to extend the VaR estimation also in a bond universe and particularly in order to estimate sovereign risk....

Government-issued longevity bonds would allow longevity risk to be shared efficiently and fairly between generations. In exchange for paying a longevity risk premium, the current generation of retirees can look to future generations to hedge their aggregate longevity risk. There are also wider...

Over the last 10 years or so a mathematical theory of bubbles has emerged, following a martingale theory based on an absence of arbitrage, as opposed to an equilibrium theory. This paper attempts to explain the major developments of the theory as it currently stands, including equities, options,...

We introduce a new approach to model the market smile for inflation-linked derivatives by defining the Quadratic Gaussian Year-on-Year inflation model -- the QGY model. We directly define the model in terms of a year-on-year ratio of the inflation index on a discrete tenor structure, which,...

Changes in collateralization have been implicated in significant default (or near-default) events during the financial crisis, most notably with AIG. We have developed a framework for quantifying this effect based on moving between Merton-type and Black-Cox-type structural default models. Our...

After taking into account biases induced by infrequent trading and selection, it is unlikely that illiquid asset classes have higher risk-adjusted returns than traditional liquid stock and bond markets. On the other hand, there are significant illiquidity premiums within asset classes. Portfolio...

We develop a dynamic valuation model of private equity (PE) investments by solving the portfolio-choice problem for a risk-averse investor (LP), who invests in a PE fund, managed by a general partner (GP). Key features are illiquidity, leverage, GP value-adding skills (alpha), and compensation,...

We present comprehensive evidence in support of giving liquidity equal standing to size, value/growth, and momentum as investment styles, as defined by Sharpe (1992). First, we show that financial market liquidity, as identified by stock turnover, is an economically significant indicator of...

This Article offers a broad theory of what distinguishes investment funds from ordinary companies, with ramifications for how these funds are understood and regulated. The central claim is that investment funds (i.e., mutual funds, hedge funds, private equity funds and their cousins) are...
