The purpose of this study is to examine the relationship of using derivative financial instruments, tax aggressiveness and firm market value.

This paper develops analytical models and designs an empirical study.

Using data from large Canadian public companies, this paper finds that a firm’s realized losses or unrealized gains from using derivatives are negatively associated with its effective tax rate, and a firm’s realized losses or unrealized gains from using derivatives are positively associated with its market value.

This study simplifies the analytical model by separating the firm’s intrinsic market value from the tax-timing option value. In a more general framework, the tax-timing option value could be subsumed in the firm’s market value, and the firm’s market value would be determined endogenously.

This study develops a framework to show how firms exploit the tax-timing option by using derivatives. It is the first study to conclude that a motive for firms to use derivatives is to exploit the tax-timing option.

The purpose of this paper is to study the disposition effect that is exhibited by the investors through the review of research articles in the area of behavioral finance. When the investors are hesitant to realize the losses and quick to realize the gains, this phenomenon is known as the disposition effect. This paper explains various theories, which have been evolved over the years that has explained the phenomenon of disposition effect. It includes the behavior of individual investors, institutional investors and mutual fund managers.

The authors have used the existing literatures from the various authors, who have studied the disposition effect in either real market or the experimental market. This paper includes literature over a period of 40 years, that is, Dyl, 1977, in the form of tax loss selling, to the most recent paper, Surya et al. (2017). Some authors have used the PGR-PLR ratio for calculating the disposition effect in their study. However, some authors have used t-test, ANNOVA, Correlation coefficient, Standard deviation, Regression, etc., as a tool to find the presence of disposition effect.

The effect of disposition can be changed for different types of individual investors, institutional investors and mutual funds. The individual investors are largely prone to the disposition effect and the demographic variables like age, gender, experience, investor sophistication also impact the occurrence of the disposition effect. On the other side, the institutional investors and mutual funds managers may or may not be affected by the disposition effect.

The skilled understanding of the disposition effect will help the investors, financial institutions and policy-makers to reduce the adverse effect of this bias in the stock market. This paper contributes a detailed explanation of disposition effect and its impacts on the investors. The study of disposition effect has been found to be insufficient in the context of Indian capital market.

The investors and society at large can gains insights about causes and influences of disposition effect which will be helpful to create sound investment decisions.

This paper has complied the 11 causes for the occurrence of disposition effect that are found by the different authors. The paper also highlights the impact of the disposition effect in the decision-making of various investors.

To raise the quality of regulatory capital, Basel III capital rules recognize unrealized gains and losses on all available-for-sale (AFS) securities in Common Equity Tier 1 Capital (CET1). However, by examining the correlations between U.S. GDP growth rate, interest rates and regulatory capital ratios computed using Basel III regulatory capital definition for six U.S. global systemically important banks (G-SIBs) since 2007, this chapter finds that Basel III regulatory capital will enhance the pro-cyclicality of Basel III leverage ratio and Tier 1 capital ratio and their sensitivity to long-term interest rates. Therefore, Basel III capital standards may have significant implications for bank supervision and bank capital risk management in the near future. As banks will hold more high-quality liquid assets (HQLAs) as required by Basel III Liquidity Coverage Ratio (LCR), the weight of unrealized gains and losses arising from fair value accounting will increase in Basel III Tier 1 capital base, the consequent increase of pro-cyclicality in a bank’s regulatory capital ratios may distort the true picture of bank capital adequacy. If an expected loss approach (EL) is used as the provisioning model, such capital risk may be increased further. Moreover, as U.S. monetary policy has started tapering quantitative easing, long-term interest rates will increase inevitably. This may increase the negative impact of unrealized gains and losses on AFS securities on bank capital. As a result, it may be difficult for banks to maintain appropriate capital ratios to meet regulatory requirements and support business activities.

Short option positions carry significant risk of losses well in excess of 100 per cent of the initial option price. Margin requirements associated with such positions are therefore considerable. The purpose of this paper is to develop a methodology for calculating margin requirement‐based option portfolio returns that realistically represent the returns realized by investors, and to demonstrate the effects of this methodology on analyses of option returns.

A methodology is developed for calculating margin requirement‐based short option portfolio returns.

Accounting for margin requirements reduces the returns of simple short option strategies by up to 92 per cent compared to the price return. In long/short portfolio analyses, use of margin requirement returns necessitates additional methodological adjustments to ensure that unwanted volatility risk is properly hedged.

The result is a portfolio return that more accurately represents the return realized by investors, and increased power to detect cross‐sectional patterns in option returns.

This study aims to investigate the association of demographic characteristics, market conditions and risk taking with the disposition effect using data on Brazilian individual investors.

This study uses a unique data set with monthly data from June 2007 to February 2017 provided by one of the largest asset management firms in Brazil. This paper computes the proportion of gains realized and the proportion of losses realized to see if investors incur the disposition effect. This paper then performs logistic regressions to verify the association between investors’ disposition effects and demographic and portfolio characteristics. This paper analyses the prevalence of cognitive biases depending on market conditions (bull or bear markets) and include regressions by asset class as robustness checks.

This paper finds evidence that risk averse investors are more prone to the disposition effect, male subjects are less prone to this cognitive bias and age is not associated with the disposition effect. This paper observes that the tendency to incur the disposition effect decreases during bull markets but increases during bear markets. Also, this paper finds that sophisticated investors are more prone to selling winning assets and holding on to losses.

First, paper gains and losses are based on the highest and lowest prices of the month and not on the price at the moment the sale occurred. Second, this paper had access only to end-of-month information, not to actual daily trading records. Third, because the data set relates to individual investors who trade investment funds, this paper cannot determine whether firm size is associated with the disposition effect. Fourth, age may not necessarily be a proxy for investor experience, so one should interpret the lack of significance for age in terms of generational differences.

This paper demonstrates that the disposition effect is prevalent even among wealthier and more educated investors with delegated asset classes. This paper also presents evidence on the association between demographic characteristics and cognitive biases considering a liquidity-constrained, highly volatile and developing market.

This paper demonstrates that gender is an important characteristic to understand cognitive biases and that investor sophistication may not necessarily be an attenuation factor for the disposition effect in a liquidity-constrained market.

This is the first study to analyse the role of demographic characteristics and risk taking to explain the disposition effect using real information at the individual level about Brazilian investors. It is also the first to analyse the intensity of cognitive biases during bull and bear markets in the Brazilian economy.

The prospect theory is potentially an essential ingredient in modeling the disposition effect. However, many scholars have tried to explain the disposition effect with the help of prospect theory and they came to opposite conclusions. The purpose of this paper is to examine the impact of value function of the prospect theory on predicting the disposition effect.

Lagrange multiplier optimization and dynamic programming method are used to solve the representative investor’s optimal portfolio choice problem. Furthermore, numerical simulation is used to compare the prediction ability of different types of value function.

The authors support that the value function has a crucial role in predicting the disposition effect with prospect theory, i.e. the curvature and boundedness of the value function may influence the performance of applying the prospect theory in the disposition effect. They conclude that a piecewise negative exponential value function can predict the disposition effect, while others like the piecewise power value function may not.

Extant literature about modeling the disposition effect with the prospect theory mostly focus on the time when gain-loss utility occurs or the selection of reference point. This paper based on the value function properties provides a new perspective in analyzing the crucial role that value function has in predicting financial market anomalies.

Prior research demonstrates that share prices reflect a risk premium that is associated with earnings variability. This suggests that managers can reduce the cost of capital and increase share prices by reducing earnings variability. In this study, we investigate bank managers' use of discretion in estimating loan loss provisions (LLP) to reduce earnings variability. We find that banks with relatively high pre‐managed earnings have positive discretionary LLP and banks with relatively low pre‐managed earnings have negative discretionary LLP, results that are consistent with the hypothesis of earnings management to reduce earnings variability. In addition, we find that bank managers' decisions to reduce earnings variability are related to the need for external financing and to gains and losses on the sale of securities which serve as substitutes for accomplishing their objective of earnings variability reduction.

The purpose of this paper is to explore the existence of disposition effect among Canadian wheat farmers when marketing their grain. This study examines the question of whether farmers wait too long to price their grain or whether they price it too soon.

The disposition effect is a common behavior documented in financial markets, and reflects the notion that investors tend to hold losing positions too long and close winning positions too fast. This idea can also be applied to grain marketing, exploring whether farmers sell their grain more readily when prices are “high” and wait longer when prices are “low.” Based on the approach by Odean (1998), marketing strategies of 15,564 farmers between 2003/2004 and 2008/2009 are examined.

Results support the existence of disposition effect in marketing decisions. Farmers seem to be eager to sell when prices offered by contracts are above their reference price and wait longer to sell when prices offered by contracts are below their reference price. There is no clear evidence that farmers might consistently benefit from this behavior. On the other hand, it is not clear whether this behavior can be costly to farmers.

Exploring the existence of disposition effect is relevant because this behavior can affect performance. If grain is sold too early, farmers can miss opportunities to sell at higher prices later. If grain is held too long, prices can go down and farmers will end up selling at lower prices. This study uses unique data to perform the first analysis of the disposition effect in the agricultural industry, and its findings can provide new insights and move us toward a more complete understanding of decision making in this industry.

In his review of 30 years of research in Prospect Theory, Barberis (2013) notes that support for Prospect Theory had come mainly from the laboratory. In this paper, I write about a recurring phenomenon in real life that is consistent with Prospect Theory predictions in decision-making loss domain. The 60 cases noted in this paper are associated with specific risk seekers that had cost more than $140 billion (an average of $2.33 billion per case). Given space consider– ations, I provide synopses for 14 cases. A few of these cases have been discussed in the extant literature in connection with internal control, but were not considered from the perspective of Prospect Theory. It is striking that these cases are costly, all participants are young men, and almost all had followed the gambler’s martingale strategy – i.e., double down. While these cases are informative about risk-seeking behavior, they are not sufficiently systematic to be subjected to stylized archival research methods.
