Asset mispricing, arbitrage, and volatility
Market efficiency remains a contentious topic among financial economists. The theoretical case for efficient markets rests on the notion of risk-free, cost-free arbitrage. In real markets, however, arbitrage is not risk-free or cost-free. In addition, the number of informed arbitrageurs and the supply of financial resources they have to invest in arbitrage strategies is limited. This article builds on an important recent model of arbitrage by professional traders who need?but lack?wealth of their own to trade. Professional abitrageurs must convince wealthy but uninformed investors to entrust ...

Deliverability and regional pricing in U.S. natural gas markets
During the 1980s and early '90s, interstate natural gas markets in the United States made a transition away from the regulation that characterized the previous three decades. With abundant supplies and plentiful pipeline capacity, a new order emerged in which freer markets and arbitrage closely linked natural gas price movements throughout the country. After the mid-1990s, however, U.S. natural gas markets tightened and some pipelines were pushed to capacity. We look for the pricing effects of limited arbitrage through causality testing between prices at nodes on the U.S. natural gas ...

Arbitrage: the key to pricing options
Arbitrage has become associated in popular attitudes with the most ruthless and profit-driven of human impulses, but the opposite reputation might be more well-deserved. The ability to arbitrage is essential for the efficient operation of markets. An interesting application of the principle of arbitrage arose when it provided the breakthrough insight in economists? solution to a formerly intractable problem: how to properly price the emergent financial instruments known as options.

Index arbitrage and nonlinear dynamics between the S&P 500 futures and cash
We use a cost of carry model with nonzero transactions costs to motivate estimation of a nonlinear dynamic relationship between the S&P 500 futures and cash indexes. Discontinuous arbitrage suggests that a threshold error correction mechanism may characterize many aspects of the relationship between the futures and cash indexes. We use minute-by-minute data on the S&P 500 futures and cash indexes. The results indicate that nonlinear dynamics are important and related to arbitrage and suggest that arbitrage is associated with more rapid convergence of the basis to the cost of carry than would ...

Interest on Reserves and Arbitrage in Post-Crisis Money Markets
Currently, Eurodollars and fed funds markets combined trade about $220 billion in funds daily, the vast majority of which with overnight tenor. In this paper, we document several features of these wholesale unsecured dollar funding markets. Using daily confidential data on wholesale unsecured borrowing and reserve balances, we show that foreign banks, which make up most of the trading volumes in these markets, keep around 99% of each additional Eurodollar and 80% of each fed fund borrowed as reserve balances. With these risk-free trades, banks earn the spread between interest on reserves and ...

Arbitrage and Liquidity: Evidence from a Panel of Exchange Traded Funds
Market liquidity is expected to facilitate arbitrage, which in turn should affect the liquidity of the assets traded by arbitrageurs. We study this relationship using a unique dataset of equity and bond ETFs compiled from big trade-level data. We find that liquidity is an important determinant of the efficacy of the ETF arbitrage. For less liquid bond ETFs, Granger-causality tests and impulse responses suggest that this relationship is stronger and more persistent, and liquidity spillovers are observed from portfolio constituents to ETF shares. Our results inform the design of synthetic ...

Empirical evaluation of asset pricing models: arbitrage and pricing errors over contingent claims
In a 1997 paper, Hansen and Jagannathan develop two pricing error measures for asset pricing models. The first measure is the maximum pricing error on given test assets, and the second measure is the maximum pricing error over all possible contingent claims. We develop a simulation-based Bayesian inference of the pricing error measures. Although linear time-varying and multifactor models are widely reported to have small pricing errors on standard test assets, we demonstrate that these models can have large pricing errors over contingent claims because their stochastic discount factors are ...

Trading risk, market liquidity, and convergence trading in the interest rate swap spread
While trading activity is generally thought to play a central role in the self-stabilizing behavior of markets, the risks in trading on occasion can affect market liquidity and heighten asset price volatility. This article examines empirical evidence on the limits of arbitrage in the interest rate swap market. The author finds both stabilizing and destabilizing forces attributable to leveraged trading activity. Although the swap spread tends to converge to its fundamental level, it does so more slowly or even diverges from its fundamental level when traders are under stress, as indicated by ...
