Relative Corporate Social Performance And Cost Of Equity Capital: International Evidence, Benjamin Lynch, Martha O'Hagan-Luff

Articles

This research examines the relationship between firms' corporate social performance (CSP) and the implied cost of equity capital using a sample of 25,938 firm-year observation from 49 countries during the period from 2002 to 2021. Using estimates of the firms' ex ante cost of equity capital, we examine its relationship with industry-relative measures of the firms' CSP, its environmental and social pillars and sub-pillars. We find that increased overall CSP reduces a firm's cost of equity capital up until a point, beyond which the marginal benefits of further CSP investment decrease. We find that the social pillar is the main …

Shifting The Eu Taxonomy From Theory To Practice: A Review Of The Literature Highlighting Potential Academic Contributions To Its Adoption, Implementation, And Impact, Dylan Kirby, Sandra Thompson, Cormac H. Macmahon

Articles

The EU Taxonomy seeks to identify those sustainable economic activities, thereby supporting climate change mitigation and adaptation. Recent legislation underpinning the EU Taxonomy, such as the Non-Financial Reporting Directive (NFRD) and the Sustainable Finance Disclosure Regulation (SFDR), highlight the urgency for academic contributions that might shed light on its operationalisation. At this embryonic stage in the Taxonomy’s lifecycle, there is potential for the academic community to contribute to understanding its implications. Hence, we undertake a thematic analysis of predominantly, but not exclusively, professional literature to prioritise potential empirical research or conceptualisations that might offer insights for finance and accounting professionals, …

This chapter will outline the key futures based hedging approaches that have been developed for managing energy price risk and evaluate their effectiveness. A key element of this analysis will be the breadth of assets considered. These include Crude and Refined Oil products, Natural Gas, and wholesale Electricity markets. We find significant differences in the …

American Option Pricing: Optimal Lattice Models And Multidimensional Efficiency Tests, Qianru Shang, Brian Byrne

Articles

We introduce a set of lattice techniques to the Leisen‐Reimer and Tian binomial models with a view to accelerating computation time and improving accuracy of American Option valuation. A level of accuracy and efficiency combined can be achieved that surpass commonly used analytical analogues. We compare these efficient lattice models with analytical formulae for pricing different groups of options according to the deepness of American quality and moneyness. Our results reveal that counter to received wisdom, lattices constructs produce greater speed and accuracy for all option categories relative to the best performing closed form American analogues.

Are Literary Agents (Really) Fiduciaries?, Jacqueline Lipton

Articles

2018 was a big year for “bad agents” in the publishing world. In July, children’s literature agent Danielle Smith was exposed for lying to her clients about submissions and publication offers. In December, major literary agency Donadio & Olson, which represented a number of bestselling authors, including Chuck Palahnuik (Fight Club), filed for bankruptcy in the wake of an accounting scandal involving their bookkeeper, Darin Webb. Webb had embezzled over $3 million of client funds. Around the same time, Australian literary agent Selwa Anthony lost a battle in the New South Wales Supreme Court involving royalties she owed to her …

The Impact Of Firm Characteristics On Speed Of Adjustment To Target Leverage: A Uk Study, James Fitzgerald, J. Ryan

Articles

Responding to the need to investigate heterogeneity in the speed of adjustment (SOA) to target leverage in a manner that reflects the fractional nature of leverage, we estimate SOA across sub-samples of UK firms using the Dynamic Panel Fractional (DPF) estimator. Using firm characteristics to identify firms subject to varying costs of deviation from and adjustment to target leverage, we find significant evidence of heterogeneity in the speeds at which UK firms adjust to target leverage. Our results show that small, high growth and low dividend paying firms adjust to target leverage faster than their large, low growth and high …

Hong Kong Unrest And Implications For The Hang Seng Index, Lucia Morales, Bernadette Andreosso-O’Callaghan

Articles

With the September 2014 ‘Umbrella Revolution’ in Hong Kong, China faced one of the biggest political challenges since the Tiananmen Square events. Beijing’s proposed electoral reform was perceived as a direct attack to democracy, and the ensuing protest triggered concerns amid local and international investors; the financial sector took the hardest hit, with stocks of companies exposed to the Hong Kong market facing significant losses. Volatility continued to increase to a seven-month high over worries that the student blockade in Hong Kong’s streets could drag on for longer than expected. The econometric-based analysis in this paper looks at the implications …

Relating Group Size And Posting Activity Of An Online Community Of Financial Investors: Regularities And Seasonal Patterns, P. Racca, R. Casarin, Pierpaolo Dondio, F. Squazzoni

Articles

Group size can potentially affect collective activity and individual propensity to contribute to collective goods. Mancur Olson, in his Logic of Collective Action, argued that individual contribution to a collective good tends to be lower in groups of large size. Today, online communication platforms represent an interesting ground to study such collaborative dynamics under possibly different conditions (e.g., lower costs related to gather and share information). This paper examines the relationship between group size and activity in an online financial forum, where users invest time in sharing news, analysis and comments with other investors. We looked at about 24 million …

Managing Energy Price Risk Using Futures Contracts: A Comparative Analysis, Jim Hanly

Articles

This paper carries out a comparative analysis of managing energy risk through futures hedging, for energy market participants across a broad dataset that encompasses the largest and most actively traded energy products. Uniquely, we carry out a hedge comparison using a variety of risk measures including Variance, Value at risk (VaR), and Expected Shortfall as well as a utility based performance metric for two different investor horizons; weekly and monthly. We find that hedging is effective across the spectrum of risk measures we employ. We also find significant differences in both the hedging strategies and the hedging effectiveness of different …

Volatility And Risk Management In European Electricity Futures Markets, Jim Hanly, Lucia Morales

Articles

This paper estimates and applies a risk management strategy for electricity spot exposures using futures hedging. We apply our approach to three of the most actively traded European electricity markets, Nordpool, APXUK and Phelix. We compare both optimal hedging strategies and the hedging effectiveness of these markets for two hedging horizons, weekly and monthly using both Variance and Value at Risk (VaR). We find significant differences in both the Optimal Hedge Ratios (OHR’s) and the hedging effectiveness of the different electricity markets. Better performance is found for the Nordpool market while the poorest performer in hedging terms is Phelix. However …

Performance Of Utility Based Hedges, Jim Hanly, John Cotter

Articles

Hedgers as investors are concerned with both risk and return. However when measuring hedging performance, the role of returns and investor risk aversion has generally been neglected in the literature, by its focus on minimum variance hedging. In this paper we address this by using utility based performance metrics to evaluate the hedging effectiveness of utility based hedges for hedgers with both moderate and high risk aversion together with the more traditional minimum variance approach. To examine this for an energy hedger, we apply our approach to WTI Crude Oil, for three different hedging horizons, daily, weekly and monthly. We …

Derivatives Pricing With Accelerated Trinomial Trees, Conall O'Sullivan, Stephen O'Sullivan

Articles

Accelerated Trinomial Trees (ATTs) are a derivatives pricing lattice method that circumvent the restrictive time step condition inherent in standard trinomial trees and explicit finite difference methods (FDMs) in which the time step must scale with the square of the spatial step. ATTs consist of L uniform supersteps each of which contains an inner lattice/trinomial tree with N non-uniform subtime steps. Similarly to implicit FDMs, the size of the superstep in ATTs, a function of N, are constrained primarily by accuracy demands. ATTs can price options up to N times faster than standard trinomial trees (explicit FDMs). ATTs can be …

The Effects Of Bank Capital Constraints On Post-Acquisition Performance, Chris Brune, Kevin Lee, Scott Miller

Articles

Researchers have shown that capital constrained firms make better acquisition decisions. However, the literature on bank mergers and acquisitions is silent on this issue. We investigate whether banks constrained by capital requirements make better acquisition decisions than non-constrained banks. We also examine the characteristics of acquisitions to identify the determinants of positive post-acquisition performance. While there are few capital constrained banks that make acquisitions, those that do demonstrate better post-acquisition performance than their nonconstrained counterparts. On average, capital constrained banks pay a lower premium for their target and favor cash over equity financing. We also find that capital constrained banks …

A Utility Based Approach To Energy Hedging, Jim Hanly, John Cotter

Articles

A key issue in the estimation of energy hedges is the hedgers’ attitude towards risk which is encapsulated in the form of the hedgers’ utility function. However, the literature typically uses only one form of utility function such as the quadratic when estimating hedges. This paper addresses this issue by estimating and applying energy market based risk aversion to commonly applied utility functions including log, exponential and quadratic, and we incorporate these in our hedging frameworks. We find significant differences in the optimal hedge strategies based on the utility function chosen.

Venture Capital In Ireland In Comparative Perspective, Frank Barry, Clare O'Mahony, Beata Sax

Articles

This paper assembles the most comprehensive set of data available to offer a comparative perspective on venture capital in Ireland. The paper charts the emergence of the sector and the co-evolution of the demand and supply sides of the market. On the demand side, a flow of investment opportunities emerged – particularly from the indigenous software sector – for which venture capital represented an appropriate financing vehicle. Concurrently, on the supply side, publicly provided funding and other elements of public policy dramatically enhanced its availability. State support to the demand-side has been a multiple of state support to the supply …

Hedging Effectiveness Under Conditions Of Asymmetry, Jim Hanly, John Cotter

Articles

We examine whether hedging effectiveness is affected by asymmetry in the return distribution by applying tail specific metrics, for example, Value at Risk, to compare the hedging effectiveness of short and long hedgers. Comparisons are applied to a number of hedging strategies including OLS, and both symmetric and asymmetric GARCH models. We apply our analysis to a dataset consisting of S&P500 index cash and futures containing symmetric and asymmetric return distributions chosen ex-post. Our findings show that asymmetry reduces out-of-sample hedging performance and that significant differences occur in hedging performance between short and long hedgers.

On The Acceleration Of Explicit Finite Difference Methods For Option Pricing, Stephen O'Sullivan, Conall O'Sullivan

Articles

Implicit finite difference methods are conventionally preferred over their explicit counterparts for the numerical valuation of options. In large part the reason for this is a severe stability constraint known as the Courant–Friedrichs–Lewy (CFL) condition which limits the latter class’s efficiency. Implicit methods, however, are difficult to implement for all but the most simple of pricing models, whereas explicit techniques are easily adapted to complex problems. For the first time in a financial context, we present an acceleration technique, applicable to explicit finite difference schemes describing diffusive processes with symmetric evolution operators, called Super-Time-Stepping. We show that this method can …

Risk Management Trends: Currency Trading Using The Fractal Market Hypothesis, Jonathan Blackledge, Kieran Murphy

Articles

We report on a research and development programme in financial modelling and economic security undertaken in the Information and Communications Security Research Group (ICSRG, 2011) which has led to the launch of a new company - Currency Traders Ireland Limited - funded by Enterprise Ireland. Currency Traders Ireland Limited (CTI, 2011) has a fifty year exclusive license to develop a new set of indicators for analysing currency exchange rates (Forex trading). We consider the background to the approach taken and present examples of the results obtained to date. In this ‘Introduction’, we provide a background to and brief overview of …

Application Of The Fractional Diffusion Equation For Predicting Market Behaviour, Jonathan Blackledge

Articles

Most Financial modelling system rely on an underlying hypothesis known as the Eficient Market Hypothesi (EMH) including the famous BlackScholes formula for placing an option. However, the EMH has a fundamental flaw: it is based on the assumption that economic processes are normally distributed and it has long been known that this is not the case. This fundamental assumption leads to a number of shortcomings associated with using the EMH to analyse financial data which includes failure to predict the future volatility of a market share value. This paper introduces a new financial risk assessment model based on Levy statistics …

Time Varying Risk Aversion: An Application To Energy Hedging, Jim Hanly, John Cotter

Articles

Risk aversion is a key element of utility maximizing hedge strategies; however, it has typically been assigned an arbitrary value in the literature. This paper instead applies a GARCH-in-Mean (GARCH-M) model to estimate a time-varying measure of risk aversion that is based on the observed risk preferences of energy hedging market participants. The resulting estimates are applied to derive explicit risk aversion based optimal hedge strategies for both short and long hedgers. Out-of-sample results are also presented based on a unique approach that allows us to forecast risk aversion, thereby estimating hedge strategies that address the potential future needs of …

Systemic Risk Assessment Using A Non-Stationary Fractional Dynamic Stochastic Model For The Analysis Of Economic Signals, Jonathan Blackledge

Articles

This paper considers the Fractal Market Hypothesis (FMH) for assessing the risk(s) in developing a financial portfolio based on data that is available through the Internet from an increasing number of sources. Most financial risk management systems are still based on the Efficient Market Hypothesis which often fails due to the inaccuracies of the statistical models that underpin the hypothesis, in particular, that financial data are based on stationary Gaussian processes. The FMH considered in this paper assumes that financial data are non-stationary and statistically self-affine so that a risk analysis can, in principal, be applied at any time scale …

Hedging: Scaling And The Investor Horizon, Jim Hanly, John Cotter

Articles

This paper examines the volatility and covariance dynamics of cash and futures contracts that underlie the Optimal Hedge Ratio (OHR) across different hedging time horizons. We examine whether hedge ratios calculated over a short term hedging horizon can be scaled and successfully applied to longer term horizons. We also test the equivalence of scaled hedge ratios with those calculated directly from lower frequency data and compare them in terms of hedging effectiveness. Our findings show that the volatility and covariance dynamics may differ considerably depending on the hedging horizon and this gives rise to significant differences between short term and …

Volatility Spillovers Between Equity And Currency Markets: Evidence From Major Latin American Countries, Lucia Morales

Articles

This paper investigates the nature of volatility spillovers between stock returns and a number of exchange rates in six Latin American countries and one European economy in the 1998-2006 period. We divide our sample into sub periods, prior to and after the introduction of the Euro and we apply the EGARCH methodology to model volatility. Our results show that the volatility of stock returns affects the volatility of exchange rates; however, we do not find evidence of volatility transmission in the opposite direction.

Upping The Ante, Thomas Power

Articles

The aim of this essay is to present the inherent barriers to the achievement of full co-operative solutions to global environmental problems. It reviews the literature of Swanson, Barrett, Pearse and Helme to explain the problems associated with multilateral bargaining and to compare two types of bargaining, namely “ex-post” and “ex-ante”. It attempts to apply the theoretical guidelines on multilateral bargaining to GATT.,

Re-Evaluating Hedging Performance, Jim Hanly, John Cotter

Articles

Mixed results have been documented for the performance of hedging strategies using futures. This paper reinvestigates this issue using an extensive set of performance evaluation metrics across seven international markets. We compare the hedging performance of short and long hedgers using traditional variance based approaches together with modern risk management techniques including Value at Risk, Conditional Value at Risk and approaches based on Downside Risk. Our findings indicate that using these metrics to evaluate hedging performance, yields differences in terms of best hedging strategy as compared with the traditional variance measure. We also find significant differences in performance between short …
