Leverage and Asset Prices: An Experiment

Abstract
This is the ?rst paper to test the asset pricing implication of leverage in a laboratory. We show that as theory predicts, leverage increases asset prices: When an asset can be used as collateral (that is, when the asset can be bought on margin), its price goes up. This increase is signi?cant, and quantitatively close to what theory predicts. However, important deviations from the theory arise in the laboratory. First, the demand for the asset shifts when it can be used as a collateral, even though agents do not exhaust their purchasing power when collateralized borrowing is not allowed. Second, the spread between collateralizable and noncollateralizable assets does not increase during crises, in contrast to what theory predicts.

En el sitio de la Unión Europea, hay un accesible FAQ sobre la regulación sobre Short Selling y Credit Default Swaps.

¿Sesgos + momentum?, maybe.

Personalmente me quedo con la tabla comparativa -cerca del final- entre la regulacion del Short Selling en USA, EU y Hong Kong.

Tal vez es una serie de post más para finanzas 301, pero los ultimos 3 post de Quantivity hacen un buen capitulo de Hedging.

Proxy / Cross Hedging

“The root challenge of two current equity risk and alpha projects boil down to hedging using non-underlying instruments, known as proxy hedging or cross hedging.”

Empirical Quantiles and Proxy Selection

“(…)how to choose an appropriate hedge instrument, especially amongst several alternatives.”

Empirical Copulas and Hedge Basis Risk

“Of particular interest is understanding the dynamics of basis risk under extreme scenarios (both up and down), which are driven by time-varying stochastic joint covariation.”

Equity Premia Around the World

Abstract: 
We update our global evidence on the long-term realized equity risk premium, relative to both bills and bonds, in 19 different countries. Our study now runs from 1900 to the start of 2011. While there is considerable variation across countries, the realized equity risk premium was substantial everywhere. For our 19-country World index, over the entire 111 years, geometric mean real returns were an annualized 5.5%; the equity premium relative to Treasury bills was an annualized 4.5%; and the equity premium relative to long-term government bonds was an annualized 3.8%. The expected equity premium is lower, around 3% to 3½% on an annualized basis.

The Role of Default in Macroeconomics

Abstract
What is the main limitation of much modern macro-economic theory, among the failings pointed out by William R. White at the 2010 Mayekawa Lecture? We argue that the main deficiency is a failure to incorporate the possibility of default, including that of banks, into the core of the analysis. With default assumed away, there can be no role for financial intermediaries, for financial disturbances, or even for money. Models incorporating defaults are, however, harder to construct, in part because the representative agent fiction must be abandoned. Moreover, financial crises are hard to predict and to resolve. All of the previously available alternatives for handling failing systemically important financial institutions (SIFIs) are problematical. We end by discussing a variety of current proposals for improving the resolution of failed SIFIs.
