We propose a joint modeling strategy for timing the joint distribution of the returns and their volatility. We do this by incorporating the potentially asymmetric links into the system of 'independent' predictive regressions of returns and volatility, allowing for asymmetric cross-correlations,...

We build a two-country model with imperfect financial intermediation. Banks face limits to arbitrage which lead to positive excess returns in the investment markets and a risk premium in the international credit market. Gross capital flows affect the exchange rate since banks are balance sheet...

The paper analyzes the intensity of choice in an agent based financial optimization problem. Mean-variance optimizing agents choose among mutual funds of similar styles but varying performance. We specify a model for the allocation of new funds, switching between funds, and withdrawals and...

In this paper, we use Bayesian nonparametric learning to estimate the skill of actively managed mutual funds and also to estimate the population distribution for this skill. A nonparametric hierarchical prior, where the hyperprior distribution is unknown and modeled with a Dirichlet process...

One of the most enduring questions in finance is the persistence of investment risk across time. Traditional finance lacks of recipes on how to approach and how to hedge non-diversifiable risks. Risks that can not be diversified at a given point in time can nevertheless be averaged over time...

We analyze the trading activity in an Internet chat room with approximately 1,300 participants. Traders make posts in real time about their activities. We find these traders are more skilled than retail investors analyzed in other studies. 55% make profits after transaction costs, and they earn...

In the aftermath of the global financial collapse that began in 2007, governments around the world have responded with reform. The outlines of Basel III have been announced, although some have already dismissed its reform agenda as being too little (and too late!). Like the proposed reforms in...

The relevancy of Minsky's Financial Instability Hypothesis (FIH) in the current (and still unfolding) crisis has been clearly acknowledged by both economists and regulators. While most papers focus on discussing to what extent the FIH or Minsky's Big Bank/Big Government interpretation is...

The world's worst economic crisis since the 1930s is now well into its third year. All sorts of explanations have been proffered for the causes of the crisis, from lax regulation and oversight to excessive global liquidity. Unfortunately, these narratives do not take into account the systemic...

In this paper I will follow Hyman Minsky in arguing that the postwar period has seen a slow transformation of the economy from a structure that could be characterized as robust to one that is fragile. While many economists and policymakers have argued that no one saw it coming, Minsky and his...
