Using country index returns from 8 developed countries and 8 emerging market countries, we re-explore the benefits to international diversification over the past 30 years. To examine various theories in a comparable way, we intentionally limited ourselves to an examination of country index returns and a limited number of types of investments.
We examine changes in banks' market-to-book ratios over the last decade, focusing on the dramatic and persistent declines witnessed during the financial crisis. The extent of the decline and its persistence cannot be explained by the delayed recognition of losses on existing financial instruments. Rather, it is declines in the values of intangibles — including customer relationships and other intangibles related to business opportunities — along with unrecognized contingent obligations that account for most of the persistent decline in market-to-book ratios.
What kinds of credit substitution, if any, occur when changes to banks' minimum capital requirements induce them to change their willingness to supply credit? The question is of first-order importance given the emergence of "macro-prudential" policy regimes in the wake of the global financial crisis, under which regulatory tools — in particular, minimum capital ratio requirements for banks — will be employed to control the supply of bank credit as part of the effort to improve the resilience of the financial system.
What does it take to drop ten strokes from your golf score? What part of Tiger Woods' game makes him a winner? Traditional golf stats can't answer these questions. Broadie, a professor at Columbia Business School, helped the PGA Tour develop its cutting-edge strokes gained putting stat. In this eye-opening new book, Broadie uses analytics from the financial world to uncover the secrets of the game of golf. He crunches mountains of data to show both professional and amateur golfers how to make better decisions on the course.
We present a model of the maturity of a bank's uninsured debt. The bank borrows funds and chooses afterwards the riskiness of its assets. This moral hazard problem leads to an excessive level of risk. Short-term debt may have a disciplining effect on the bank's risk-shifting incentives, but it may lead to inefficient liquidation. We characterize the conditions under which short-term and long-term debt are feasible, and show circumstances under which only short-term debt is feasible and under which short-term debt dominates long-term debt when both are feasible.
This paper presents a framework for addressing normative accounting issues for reporting to shareholders. The framework is an alternative to the emerging Conceptual Framework of the International Accounting Standards Board and the Financial Accounting Standards Board. The framework can be broadly characterized as a utilitarian approach to accounting standard setting. It has two main features. First, accounting is linked to valuation models under which shareholders use accounting information to values their stakes.
Hedge fund managers trade o the benefits of leveraging on the alpha-generating strategy against the costs of inefficient fund liquidation. In contrast to the standard risk-seeking intuition, even with a constant-return-to-scale alpha-generating strategy, a risk-neutral manager becomes endogenously risk-averse and decreases leverage following poor performance to increase the fund's survival likelihood. Our calibration suggests that management fees are the majority of the total compensation.
How likely is a catastrophic event that would substantially reduce the capital stock, GDP, and wealth? How much should society be willing to pay to reduce the probability or impact of a catastrophe? We answer these questions and provide a framework for policy analysis using a general equilibrium model of production, capital accumulation, and household preferences.
