Index-option pricing with stochastic volatility and the value of accurate variance forecasts

In pricing primary-market options and in making secondary markets, financial intermediaries depend on the quality of forecasts of the variance of the underlying assets. Hence, pricing of options provides the appropriate test of forecasts of asset volatility. NYSE index returns over the period of 1968–1991 suggest that pricing index options of up to 90-days maturity would be more accurate when: (1) using ARCH specifications in place of a moving average of squared returns; (2) using Hull and White's (1987) adjustment for stochastic variance in the Black and Scholes formula; (3) accounting explicitly for weekends and the slowdown of variance whenever the market is closed.

The intra-day impact of block trades on the Australian stock exchange

This study is concerned with the impact of block trades on transaction prices, themarket bid-ask spread and the frequency of trading on the Australian Stock Exchange. Access to a unique microstructure database enabled the resolution of a number of research design issues in earlier, mainly US-based, studies. Contrary to previous findings, there is no evidence of either a price reversal or changes in the market bid-ask spread surrounding block trades. Further, there is no evidence of an increase in the frequency of trades surrounding block trades. These contrasting results warrant closer inspection of the alternative market structures underlying the different exchanges.The authors are from the Department of Finance, the University of Sydney, Australia.

How does competition affect real earnings management to meet or beat targets? Evidence from import tariff reductions

Targets provide incentives for earnings management, and a longstanding question is whether earnings management is undertaken opportunistically or to communicate private information about future firm value. To discriminate between these motivations, I follow analytical research showing that an increase in competition through a large decrease in tariffs disciplines managers and better aligns their interests with those of shareholders. Thus, if earnings management reflects managerial opportunism, then an increase in competition will decrease earnings management; and if it signals future performance expectations, then an increase in competition will increase earnings management. Consistent with earnings management indicating managerial opportunism, I show that an increase in competition decreases real earnings management to avoid reporting negative earnings or a negative change in earnings. In addition, by showing that the lessening of trade barriers through import tariff reductions reduces the use of real earnings management to meet or beat earnings targets, I provide evidence on the role of macroeconomic conditions as a determinant of earnings quality.     

Analysis of the SRISK measure and its application to the Canadian banking and insurance industries

In this paper, we analyse, modify, and apply one of the most widely used measures of systemic risk, SRISK, developed by Brownlees and Engle (in Rev Financ Stud 30:48–79, 2016). The measure is defined as the expected capital shortfall of a firm conditional on a prolonged market decline. We argue that segregated funds, also known as separate accounts in the US, should be excluded from actuarial liabilities when SRISK is calculated for insurance companies. We also demonstrate the importance of careful analysis of accounting standards when specifying the prudential capital ratio used in SRISK methodology. Based on the proposed adjustments to SRISK, we assess the systemic risk of the Canadian banking and insurance industries. It is shown that in its current implementation, the SRISK methodology substantially overestimates the systemic risk of Canadian insurance companies.     

Solving an asset pricing model with hybrid internal and external habits,and autocorrelated Gaussian shocks

We derive an explicit formula for the price-dividend ratio of a generalized version of Abel’s asset pricing model. This model is generalized in two ways: first, consumption (dividend) growth is assumed to be an AR(1) process subject to Gaussian random shocks, and second, the investor’s preferences are allowed to be a convex combination of internal and external habits. With an internal habit weight, 50%, and a coefficient of risk aversion, 3.25, simulation results match the historic US equity premium and risk free interest rate.      

A multi-organizational cross-sectoral collaboration: empirical evidence from an ‘Empty Homes’ project

This paper analyses the processes, outcomes and tensions of a cross-sectoral collaborative venture involving several organizations with multiple logics and is based on empirical evidence from a collaborative ‘Empty Homes’ project. While, paradoxically, multiple logics are a basis for the partnership's existence (for example ‘value for money’ and local community benefit) to achieve these different aims simultaneously, its other aims or logics at times conflicted, resulting in intra-partnership tensions. Hence we offer novel insights into the practical aspects of collaboration at a local level and on multi-organizational relationships.     

Financializing Desalination: Rethinking the Returns of Big Infrastructure

Against the trend prevalent during the 1990s and 2000s, large‐scale infrastructural projects have made a comeback in the water sector. Although sometimes framed as part of a broader sustainable transition, the return of big infrastructure is a much more complicated story in which finance has played a crucial role. In the following article, we explore this encounter between finance and water infrastructure using the case of Britain's first experiment in desalination technologies, the Thames Water Desalination Plant (TWDP). On the surface, the plant appears to be a classic example of the successes of normative industrial ecology, in which sustainability challenges have been met with forward‐thinking green innovations. However, the TWDP is utterly dependent on a byzantine financial model, which has shaped Thames Water's investment strategy over the last decade. This article returns to the fundamental question of whether London ever needed a desalination plant in the first place. Deploying an urban political ecology approach, we demonstrate how the plant is simultaneously an iconic illustration of ecological modernization and a fragile example of an infrastructure‐heavy solution to the demands of financialization. Understanding the development of the TWDP requires a focus on the scalar interactions between flows of finance, waste, energy and water that are woven through the hydrosocial cycle of London.     

Dysfunctional learning in decision processes: the case of employee reciprocity

While traditional economic models characterize individuals as boundlessly self‐interested, decades of empirical findings suggest that individuals' self‐interest motives are constrained by concurrent preferences for fairness. Individuals act on these preferences by behaving reciprocally: rewarding others perceived as behaving fairly and punishing others perceived as behaving unfairly. Successful firms must learn to navigate environments characterized by the reciprocity of their transaction partners. This paper investigates firms' judgments about employee reciprocity and posits a dysfunctional learning process whereby firms that overestimate employee reciprocity learn to correct their beliefs through feedback, while those that underestimate employee reciprocity do not. The result, demonstrated through computer simulation, is a systematic bias toward an overemphasis on employee self‐interest, and a resulting inefficiency in wage choices that hurts firm profitability.

Implications for brokerage firms’ financial disclosures: From CSR perspectives

Given the importance of transparency in today's financial environment, it is surprising that limited research has examined investors’ attitudes toward brokerage firms’ financial disclosures and how their attitudes toward brokerage firms’ financial disclosures influence subsequent responses such as perceived trust and attitude toward brokerage firms. Research on Corporate Social Responsibility (CSR) practices and the Social Contract Theory suggests that investors may put a relatively high value on brokerage firms that practice financial disclosures responsibly. This research probed the relevance of this assumption by testing the relations among investors’ attitudes toward brokerage firms’ financial disclosures, attitudes toward CSR practices, perceived trust toward brokerage firms, attitudes toward brokerage firms and behavioral intentions toward brokerage firms with a survey study. The study used brokerage firms’ financial disclosures in general as the focus of this study's survey questions and a convenience sample consisting of investors. The results suggested that investors’ positive attitudes toward brokerage firms’ financial disclosures positively enhanced their attitudes toward brokerage firms’ CSR practices and perceived trust toward brokerage firms, whereas investors’ attitudes toward brokerage firms’ CSR practices mediated their attitudes toward financial disclosures to enhancing their perceived trust toward brokerage firms. Moreover, investors’ attitudes toward brokerage firms mediated their perceived trust toward brokerage firms on enhancing their behavioral intentions toward brokerage firms.
