Is the synthetic stock price really lower than actual price?

Conventional wisdom suggests synthetic stock prices are lower than actual prices due to short-sale constraints and voting premiums. This study finds that such underpricing of the synthetic midquote disappears if arbitrageurs face security borrowing costs. The synthetic spread predominantly contains the actual spread. Synthetic stock overpricing is as common as underpricing but the former is more persistent and more profitable. The difference between synthetic and actual quotes is significantly affected by options market makers' hedging costs and investors' demand for leverage.     

The cyclical effect of default risk on industrial bond yields

This paper examines the determinants of default-risk premiums and the ways in which they change over the business cycle. Seven default-risk factors are constructed from a large number of financial ratio/accounting variables. Factor scores summarizing these variables for a sample of industrial corporations are regressed with bond risk premiums for all years from 1971 to 1977—a complete business cycle. A second sample covering the years 1975 to 1977 is also examined. The main conclusion is that the cyclical movement of business conditions influences investors' assessments of default risk. Bonds issued in periods of economic normalcy have premiums that are significantly associated with earnings instability in addition to sales and size factors. By contrast, firms issuing bonds during recessionary climates must have relatively greater size and profitability to obtain funding at lower-interest costs. Firms with higher sales turnover ratios and, therefore, greater earnings instability with respect to economic downswings, are less likely to issue debt securities during depressed business conditions.     

Optimal investment,derivative demand,and arbitrage under price impact

This paper studies the optimal investment problem with random endowment in an inventory‐based price impact model with competitive market makers. Our goal is to analyze how price impact affects optimal policies, as well as both pricing rules and demand schedules for contingent claims. For exponential market makers preferences, we establish two effects due to price impact: constrained trading and nonlinear hedging costs. To the former, wealth processes in the impact model are identified with those in a model without impact, but with constrained trading, where the (random) constraint set is generically neither closed nor convex. Regarding hedging, nonlinear hedging costs motivate the study of arbitrage free prices for the claim. We provide three such notions, which coincide in the frictionless case, but which dramatically differ in the presence of price impact. Additionally, we show arbitrage opportunities, should they arise from claim prices, can be exploited only for limited position sizes, and may be ignored if outweighed by hedging considerations. We also show that arbitrage‐inducing prices may arise endogenously in equilibrium, and that equilibrium positions are inversely proportional to the market makers' representative risk aversion. Therefore, large positions endogenously arise in the limit of either market maker risk neutrality, or a large number of market makers.     

The impact of skewness in the hedging decision

The impact of skewness in the hedger's objective function is tested using a model of hedging derived from a third‐order Taylor Series approximation of expected utility. To determine the effect of price skewness upon hedging and speculation, analytical results are derived using an example of cotton storage. Findings suggest that when forward risk premiums and price skewness in the spot asset have opposite signs, speculation increases relative to the mean‐variance model. When the signs are identical, speculation will decrease, contradicting findings of mean‐variance models. © 2006 Wiley Periodicals, Inc. Jrl Fut Mark 26:503–520, 2006     

Causality in futures markets

This study tests causal hypotheses emanating from theories of futures markets by utilizing methods appropriate for disproving causal relationships with observational data. The hedging pressure theory of futures markets risk premiums, the generalized version of the normal backwardation theory of Keynes, is rejected. Theories predicting that the activity levels of speculators or uninformed traders affect levels of price volatility, either positively or negatively, are also rejected. © 2006 Wiley Periodicals, Inc.

Determinants of corporate hedging and derivatives: A revisit

Although the primary purpose of hedging is to reduce earnings volatility, corporate hedging may also increase firm value. Using publicly-available data, we found that hedging reduces the probability of financial distress, reduces the agency costs of debt, and reduces some agency costs of equity. However, we found no support for the hypothesis that hedging increases firm value by reducing expected tax liability. In addition, we suggest that corporate ownership structure may affect the desirability of hedging. We also found that large firms have a stronger tendency to hedge, firms with a larger percentage of value derived from growth opportunities are more likely to hedge, and convertible debt serves as a substitute for corporate hedging. With a dummy variable for multinational corporations as a proxy for operational hedging, we found that operational hedging and derivative hedging are complements rather than substitutes.     

Disappearing and Reappearing Dividends in Emerging Markets: Evidence from Indian Companies

This article examines the empirical determinants of dividend payout policy for 947 sample firms listed on the Bombay Stock Exchange (BSE) in India from 1995 to 2013. The author identifies three distinct trends in the propensity to pay dividends between 1995 and 2013. The regression analysis suggests that most of the decline is due to the dividend payout policies of smaller, less profitable, younger firms and firms with comparatively more investment opportunities, high financial leverage, high business risk, and high dividend distribution tax. The author finds significant positive impact of catering incentives on the propensity to pay dividends, thus supporting catering theory of dividends.     

Some factors determining municipal revenue bond interest costs

This paper tests for variations in risk premiums on municipal revenue bonds that are related to the geographic location of the issuer, the issue's second rating, and secondary collateral provisions. The empirical findings indicate that investors required risk premiums that depended on local economic conditions. Issuer borrowing costs were also shown to be related to factors that cause or reinforce segmentation of the tax-exempt bond market.     

Examining Determinants of Foreign Wage Premiums in China

We estimate foreign wage premiums for every 3‐digit manufacturing industry in China and discover a wide range of premiums both for ‘foreign’ ownership and for overseas Chinese ownership. Foreign ownership generates larger and more prevalent wage premiums than overseas Chinese ownership, but both produce premiums that respond similarly in estimates of determinants. Using the number of computers per worker to measure firms' technology levels, we find evidence consistent with the hypothesis that foreign firms pay higher wages to reduce the risk of worker turnover and the accompanying technology leakage in 76 to 78 per cent of industries. However, this determinant explains only 5 to 6 per cent of the foreign wage premium. We find the most intensive support for the ‘fair wage’ hypothesis that foreign firms pay higher wages because they are more profitable than domestic firms and workers in more profitable firms expect to be paid more, otherwise they will shirk. This hypothesis explains an average of 8 to 9 per cent of the foreign wage premiums, with support found in 72 to 75 per cent of the industries. When we consider the best combination of explanatory variables to include in each industry's wage regression, we find evidence consistent with our combined hypotheses in most industries, but we still find large residual foreign wage premiums.     

Market Price of Risk: A Comparison among the United States,United Kingdom,Australia and Japan*

This study examines and compares the market price of risk of the S&P 500, FTSE 100, All Ordinaries, and Nikkei 225 markets from 1984 to 2009 in the framework of Intertemporal Capital Asset Pricing Model (ICAPM). We follow the Vector Autoregressive instrumental variable approach in identifying the risk and hedge components of market returns and argue that in the context of market integration, covariance with a world market portfolio is a better measure of market risk than conditional market variance. Evidence is documented in support of using covariance as a risk measure in explaining market risk premiums in the Australian and Japanese markets. CAY, the consumption wealth ratio from the US market is found to be a robust state variable that helps to explain both conditional variance and covariance processes in the four markets. The market prices of risk, after controlling for the hedging demands, are positive and significant with the United States having the highest price of risk. The results are confirmed using a series of robustness tests that include varying the sampling interval.     

Yield curve risks in currency carry forwards

We provide empirical evidence that cross-country yield curve gaps (parallel gap, twist gap, and butterfly gap) are predictive to the expected currency carry premiums using currency forward contracts. We find that the expected currency gains are more notable as these yield curve risk factors at time t indicate short-term bond prices of investment currencies to go up (positive parallel movement, negative twist, and positive butterfly). We also find carry gains are more sensitively affected by cross-country monetary shocks than currency-country inflation pressures and business cycles. Our findings support that cross-country yield curve risk premiums still exist even after considering transaction costs.     

Optimal partial hedging of options with small transaction costs

This study uses asymptotic analysis to derive optimal hedging strategies for option portfolios hedged using an imperfectly correlated hedging asset with small fixed and/or proportional transaction costs, obtaining explicit formulae in special cases. This is of use when it is impractical to hedge using the underlying asset itself. The hedging strategy holds a position in the hedging asset whose value lies between two bounds, which are independent of the hedging asset's current value. For low absolute correlation between hedging and hedged assets, highly risk‐averse investors and large portfolios, hedging strategies and option values differ significantly from their perfect market equivalents. © 2011 Wiley Periodicals, Inc.

Hedging and value at risk

In this article, it is shown that although minimum‐variance hedging unambiguously reduces the standard deviation of portfolio returns, it can increase both left skewness and kurtosis; consequently the effectiveness of hedging in terms of value at risk (VaR) and conditional value at risk (CVaR) is uncertain. The reduction in daily standard deviation is compared with the reduction in 1‐day 99% VaR and CVaR for 20 cross‐hedged currency portfolios with the use of historical simulation. On average, minimum‐variance hedging reduces both VaR and CVaR by about 80% of the reduction in standard deviation. Also investigated, as an alternative to minimum‐variance hedging, are minimum‐VaR and minimum‐CVaR hedging strategies that minimize the historical‐simulation VaR and CVaR of the hedge portfolio, respectively. The in‐sample results suggest that in terms of VaR and CVaR reduction, minimum‐VaR and minimum‐CVaR hedging can potentially yield small but consistent improvements over minimum‐variance hedging. The out‐of‐sample results are more mixed, although there is a small improvement for minimum‐VaR hedging for the majority of the currencies considered. © 2006 Wiley Periodicals, Inc.

BILATERAL COUNTERPARTY RISK UNDER FUNDING CONSTRAINTS—PART I: PRICING

This and the follow‐up paper deal with the valuation and hedging of bilateral counterparty risk on over‐the‐counter derivatives. Our study is done in a multiple‐curve setup reflecting the various funding constraints (or costs) involved, allowing one to investigate the question of interaction between bilateral counterparty risk and funding. The first task is to define a suitable notion of no arbitrage price in the presence of various funding costs. This is the object of this paper, where we develop an “additive, multiple curve” extension of the classical “multiplicative (discounted), one curve” risk‐neutral pricing approach. We derive the dynamic hedging interpretation of such an “additive risk‐neutral” price, starting by consistency with pricing by replication in the case of a complete market. This is illustrated by a completely solved example building over previous work by Burgard and Kjaer.

Randomized Stopping Times and American Option Pricing with Transaction Costs

In a general discrete-time market model with proportional transaction costs, we derive new expectation representations of the range of arbitrage-free prices of an arbitrary American option. The upper bound of this range is called the upper hedging price, and is the smallest initial wealth needed to construct a self-financing portfolio whose value dominates the option payoff at all times. A surprising feature of our upper hedging price representation is that it requires the use of randomized stopping times (Baxter and Chacon 1977), just as ordinary stopping times are needed in the absence of transaction costs. We also represent the upper hedging price as the optimum value of a variety of optimization problems. Additionally, we show a two-player game where at Nash equilibrium the value to both players is the upper hedging price, and one of the players must in general choose a mixture of stopping times. We derive similar representations for the lower hedging price as well. Our results make use of strong duality in linear programming.     

Investor Sentiment and Return Predictability in Agricultural Futures Markets

This study examines the usefulness of trader‐position‐based sentiment index for forecasting future prices in six major agricultural futures markets. It has been found that large speculator sentiment forecasts price continuations. In contrast, large hedger sentiment predicts price reversals. Small trader sentiment hardly forecasts future market movements. An investigation was performed into various sentiment‐based timing strategies, and it was found that the combination of extreme large trader sentiments provides the strongest timing signal. These results are generally consistent with the hedging‐pressure theory, suggesting that hedgers pay risk premiums to transfer nonmarketable risks in futures markets. Moreover, it does not appear that large speculators in the futures markets possess any superior forecasting ability. © 2001 John Wiley & Sons, Inc. Jrl Fut Mark 21:929–952, 2001     

Cultural Dimensions,Risk Aversion and Corporate Dividend Policy

ABSTRACT

How does risk aversion affect corporate dividend payout? Finance theories have long suggested a relationship between risk aversion and dividends but there is little empirical evidence on the extent of this relationship. In this paper we construct measures of risk based on two cultural dimensions developed by Hofstede (1983, 1991). Using over ten years of data for firms in 14 countries, this study is the first to provide evidence that firms in countries with higher risk aversion exhibit both lower dividend ratios and lower propensity to pay dividends.     

The untold story of commodity futures in China

We investigate the behavior of commodity futures risk premia in China. In the presence of retail-dominance and barriers-to-entry, the term structure and momentum premia remain persistent, whereas hedging pressure, skewness, volatility, and liquidity premia are distorted by time-varying margins and strict position limits. Furthermore, open interest, currency, and inflation premia are sensitive to institutional settings. The observed premia cannot be attributed to common risks, sentiment, transactions costs, or data-snooping, but are related to liquidity, anchoring, and regulation-induced limits-to-arbitrage. We highlight the distinctive features of Chinese futures markets and assess the challenges posed to theories of commodity risk premia.
