  • Risk, competition and cost efficiency in the Chinese banking industry   Order a copy of this article
    by Yong Tan, Christos Floros 
    Abstract: Using a sample of Chinese commercial banks over the period 2003-2013, this paper tests the interrelationships between credit risk, competition and cost efficiency in the Chinese banking industry under a three-stage least square estimator. The findings suggest that a higher level of competition leads to higher credit risk of Chinese commercial banks and a higher level of efficiency leads to lower credit risk. In addition, it is found that higher level of efficiency results in higher level of competition in the Chinese banking industry and higher levels of credit risk precede an increase in the level of competition. Finally, the results show that Chinese commercial banks with higher levels of credit risk have lower levels of cost efficiency and competition-efficiency hypothesis holds in the Chinese banking industry. The results provide policy implications to the Chinese government and banking regulatory authorities.
    Keywords: credit risk; competition; cost efficiency; Chinese banking; three-stage least square.

  • Time Varying Volatility and Asymmetric News Effect during Financial Crises Evidence from DJIA, S&P 500, NASDAQ and FTSE 100 Indices   Order a copy of this article
    by SAMER AL-RJOUB, Husam Azzam 
    Abstract: We look at historical episodes in the United States over the last one hundred years of major stock market crashes in the Dow Jones industrial average, the S&P 500 and the NASDAQ indices to examine the effect of financial crises on stock returns and the news effect. Our Main results are: I) Crises affect stock market returns negatively. II) The monotonic relationship between risk and return is more obvious during crises than without crises. III) Volatility of stock returns is high during crises IV) The asymmetric news effect (leverage effect) is negative and statistically different from zero for the three indices in all scenarios. V) The asymmetric news effect is more obvious for the weekly stocks returns Based on these results, we believe that people's reaction is homogenous and recurs. Psychological factors affect invertors behavior during crises where panic magnifies the effect of crises and is reflected in the form of increased volatility and overreaction to bad news. In addition we replicate the same tests on the FTSE 100 of UK and results coincide.

  • Leverage and investment: A view of prominent role of state ownership   Order a copy of this article
    by Duc Nam Phung, Thi Phuong Thao Hoang 
    Abstract: The study investigates the relationship between leverage and investment in the presence of state ownership in an emerging market. The paper finds that leverage is negatively correlated to corporate investment. This negative relationship is different among firms with different growth opportunities in which the negative relation is significantly larger for low growth companies than high growth ones. Furthermore, when the role of state ownership at both bank and firm levels is taken into account, we find that state ownership tends to attenuate the negative relationship between leverage and investment. The results imply a biased and less-constrained lending policy of a banking system wherein state-owned banks dominate. This bias, in turn, causes over-and-inefficient investments in state-owned firms.
    Keywords: Corporate Governance; Leverage; Investment; State Ownership.

  • Stock Market Predictability 2000-2014: the effect of the Great Recession   Order a copy of this article
    by Nektarios Michail 
    Abstract: The return predictability of 242 companies with continuous daily trading in the Standard and Poors index during the 2000-2014 period is examined using rolling variance ratio tests. The results indicate that predictability is time-varying and stock-specific, a finding which is in accordance to the Adaptive Market Hypothesis. During the Great Recession the number of stocks whose returns were found to be predictable increased substantially, especially during the period of Lehman Brothers bankruptcy. Importantly, predictability is found to be driven by changing market conditions, such as stock market volatility and economic fundamentals.
    Keywords: stock market predictability; adaptive markets; Great Recession; mean reversion.

  • Securitization, Loan Specialization and Bank Risk   Order a copy of this article
    by Kenneth A. Tah 
    Abstract: This study examines the effect of securitization on the loan portfolio, investigating its impact on bank loan specialization. Using U.S. bank holding company data from 2001: Q2 to 2014: Q1, I find a positive relation between securitization and bank loan specialization, driven primarily by securitized mortgages. This study in addition examines securitizations effect on the negative relationship (as observed in previous studies) between loan specialization and bank risk, finding that within the period of our studies, securitization weakens that relationship. Such results suggest that within the focus period of this study, mortgage backed securitization in particular resulted in an overall specialization of credit, in ways that weakens the risk benefit associated with loan specialization.
    Keywords: Securitization; loan specialization; bank risk; bank holding company; mortgage backed securitization.

  • Basel 3.5 vs Basel III A radical overhaul of the Capital Requirements Pillar The case of commodity exposures   Order a copy of this article
    by Adrian Rossignolo 
    Abstract: Following the implementation of Basel III, the Basel Committee has embarked on a thorough review of its market risk directives and enacted new proposals generically called Basel 3.5. They involve a radical transformation of the Standardised Approach (SA) into a risk-sensitive method and a complete overhaul of the Internal Models Approach (IMA) through the replacement of VaR for ES, amid stringent validation standards. rnThe study analyses Basels recent regulations for commodities exposures, finding a substantial rise in capital levels for SA and IMA and the relatively disadvantageous position in which IMA is placed, arising from the higher SAs capital requirements and the tougher evaluation criteria only attained by schemes featuring Extremes Theory. This, in turn, provokes accuracy disincentives and unnecessary immobilisation of funds.rnConsequently, the paper introduces a straightforward solution designed to level SA and IMA and provide substantial protection against huge market slumps with more reasonable capital levels and reduced implied costs.rn
    Keywords: Basel 3.5; Basel III; Standardised Approach; Internal Models Approach; Expected Shortfall; Extreme Value Theory.

  • Cash flow sensitivities and bank-finance shocks in nonlisted firms   Order a copy of this article
    by Charlotte Ostergaard, Amir Sasson, Bent E. Sørensen 
    Abstract: We study how small firms manage cash flows by estimating cash flow sensitivities for all sources and uses of cash. Our data are Norwegian nonlisted firms which can be matched to the banks they borrow from. Firms with low cash holdings mainly use external finance to offset cash flow fluctuations over the cycle, whereas firms with high cash holdings rely mainly on internal finance. Estimating how cash flow sensitivities change with exogenous bank shocks, we find that the cyclicality of cash-poor firms' investment is amplified because they do not substitute internal for external finance. Our results imply that for small firms, the transmission of financial shocks to the real economy is closely tied to their accumulation of cash.
    Keywords: Cash Holdings; Cash Management; SMEs; Cash Flow Sensitivity; Bank Lending Channel.

  • The Earnings Announcements Consequences in Public Family Firms   Order a copy of this article
    by Elisabete Simões Vieira 
    Abstract: This paper investigates the market reaction to earnings announcements in public family firms, seeing whether these announcements affect firms return, liquidity and cost of capital. We analyse a sample of Portuguese listed firms for the period 2000-2013, using the event study and a panel data approach. Overall, we find no support for the earnings signalling and the efficient market hypotheses. We find no significant differences between family and non-family firms in what concerns performance. Firms size and age contribute positively to the firms performance. Finally, we find no significant relationship between earnings changes and firms liquidity and weighted average cost of capital, giving no support for the pecking order theory. This study is of interest to scholars and practitioners in the finance field, namely the information content of earnings and the differences between listed family and non-family firms in what concerns the earnings announcements effects.
    Keywords: earnings announcements; return; liquidity; cost of capital; family firms.

  • Actively versus Passively Managed Equity ETFs: New Empirical Insights   Order a copy of this article
    Abstract: This study employs a sample of 37 active and passive ETF pairs investing in common equity stocks to assess their performance and risk up to December 31, 2016. Several return metrics are computed such as absolute, buy-and-hold returns and risk-adjusted returns. Moreover, cross-sectional regression analysis is applied trying to identify the factors that may influence the performance of ETFs. Finally, the ability of managers to time the market is examined. The findings are similar to those in the previous literature. Active ETFs fall short in terms of performance and overall risk when compared their passive counterparts also failing to deliver any material excess-market return. In addition, active ETF managers are lacking in superior market timing skills. Finally, the performance of ETFs is found to be related with expenses and volume in a negative fashion while a positive relationship is revealed between performance and the assets invested in ETFs.

  • The propensity to pay dividends: empirical evidence from the MENA region   Order a copy of this article
    by Panagiotis Andrikopoulos, Osama El-Ansary, Walid Ibrahim Hassan 
    Abstract: This paper investigates the relation between stock market sentiment and firms propensity to pay dividends in the MENA region for the period 2000- 2015. Using conventional determinants of cash distributions as control variables, our results show that the tendency to pay dividends is negatively related to the aggregate investors sentiment but positively related to the dividend premium. Unlike prior literature, we report no association between firms dividend policy and issues of stock market liquidity. Overall, we suggest that corporate payout policies in the case of the MENA region can best be explained by the dividend catering hypothesis.
    Keywords: Dividends; payout policy; sentiment index; market volatility.

  • Working Capital Management and Financial Performance of UK Listed Firms: A Contingency Approach   Order a copy of this article
    by Ishmael Tingbani 
    Abstract: Existing empirical research findings generally suggest that working capital management (WCM) affects and the firms financial performance. This paper adopts contingency theory framework to investigate how the relationship between WCM and financial performance is affected by the firms environment, resources and management capability. Our sample consist of an unbalanced panel of 802 firms listed on the London Stock Exchange (LSE) from 2004 to 2014 on which a dynamic panel data analysis was performed using a series of interactive models to estimate the relationship. The findings suggest that the impact of WCM on financial performance changes to reflect number contingency variables such as environmental, resources and management capabilities of the firm. These findings are significant because they demonstrate for the first time how the firms ability to enhance performance through investment in working capital is influenced by contingent factors such as environmental, resource and management capabilities of the firm. Our results are also important as they show that contingency theory helps to provide an understanding on the conditions under which investment in working capital can be an effective tool in enhancing financial performance and the relevant contingencies.

  • The Dividend Puzzle: Testing the Signalling Hypothesis in an European Context   Order a copy of this article
    by Júlio Lobão, Luís Pacheco, Tiago Lajas 
    Abstract: Dividend policy continues to puzzle researchers in the discipline of finance. In this paper we test the signalling effects of the dividend payout for a set of European firms that had sustained earnings growth for a minimum period of five years with a decline in the last year. To the best of our knowledge this is the first paper to run and compare the results of several different models including the recently created Simultaneous-Equation Model in its linear and nonlinear forms alongside a simple OLS based estimation. Our results show that managers change dividends to signal equity-scaled earnings prospects instead of asset-scaled earnings. We also find evidence that managers change dividends for signalling previous earnings changes and may distribute dividends to reduce agency costs. These findings suggest that managers identify shareholders as the accepters of dividends and the most direct targets to signalling information.
    Keywords: Dividends; Signalling Hypothesis; Behavioural Finance.

  • An Econometric Investigation of Hedging Performance of Stock Index Futures in Korea: Dynamic versus Static Hedging   Order a copy of this article
    by Mohammad Hasan, Toufiq Choudhry, Yuanyuan Zhang 
    Abstract: Employing daily data of stock index and stock index futures, this paper empirically investigates the hedging effectiveness of time-varying hedge ratios of emerging futures markets using South Korea as a case. This paper employs eight variants of GARCH models to estimate the hedge ratios along with the conventional methods, and compares the hedging effectiveness of these estimated hedge ratios across model specifications using both within-sample and out-of-sample forecasting performances. In contrast to recent research findings, hedging performance based on a conventional OLS method outperforms the GARCH class models.
    Keywords: Stock index futures; time-varying hedge ratio; GARCH model; hedging effectiveness.

  • Split credit ratings of banks in times of crisis   Order a copy of this article
    by Surraya Rowe 
    Abstract: This paper analyses whether opacity of bank creditworthiness increases during crisis periods and if the conservativeness of CRAs changes through business cycles. Univariate and multivariate methodologies are used: data from Moodys and S&P on credit ratings and watch status for 133 commercial banks across 17 developed countries from 2007 to 2015 is employed. The univariate analysis is a unique technique that provides a new perspective to assess whether splits between CRAs are defined as permanent or temporary. The evidence demonstrates that Moodys and S&P frequently disagree. S&P is shown to be the more conservative CRA overall, however, the extent to which Moodys issues higher ratings decreases over time until it becomes the more conservative CRA. The paper is the first of its kind to establish that the conservativeness of Moodys and S&P changes throughout business cycles, which should impact on the strategic decision making of investors.

  • Going-Concern Opinions and Corporate Governance   Order a copy of this article
    by Ning Ren, Yun Zhu 
    Abstract: This paper looks into the issuance of auditors going-concern opinions and investigates how it triggers subsequent changes in corporate governance, specifically, the corporate control, executive compensation and management turnover. Using a difference-in-difference approach with the exogenous shock of Auditing Standard No. 5 (AS5) in 2007, we find that going-concern opinion leads to the decrease in blockholder ownership and institutional ownership, the reduction in CEOs cash compensation and total compensation, and the increase in the turnovers of top executives and auditors, indicating strong monitoring function of the auditors.
    Keywords: going-concern opinion; corporate governance; blockholder ownership; institutional ownership; CEO compensation; CEO turnover.

  • Managerial overconfidence and M&A performance:Evidence from China   Order a copy of this article
    by Jie Michael Guo, Jia Liu, QIan He, Jiayuan Xin 
    Abstract: We examine the extent to which managerial overconfidence creates value to acquirers in successful M&As undertaken by Chinese listed firms in the period of 20062012. The empirical results show that Chinese acquirers gain value in both the shortrun and the longrun after the M&A announcement. Our study provides new evidence that the market responds favorably to M&A deals undertaken by acquirers with more managerial overconfidence in both the short run and the long run. Our multivariate analyses, however, show that managerial overconfidence has a minimal role in explaining the stock price movement. In addition, we find that firm size is an important determinant for the relationship between overconfidence and market reaction to merger deals. Taken together, we conclude that managerial overconfidence has little effect in driving merger and acquisition deals in China.
    Keywords: Mergers and Acquisitions; Market Performance; Managerial Overconfidence; Chinese Market.

  • Market reaction to the European antitrust investigations in the payment card industry   Order a copy of this article
    by Francesca Battaglia 
    Abstract: This paper aims to analyze the stock price reaction of European banks involved in antitrust authority interventions regarding the payment card business. The main objective is to assess whether market discipline is effective and able to complement regulation (Berger et al., 2000) despite the opacity of the business (Morgan, 2002). To this end, we collect all interventions made by both domestic antitrust authorities and by the European Commission to investigate and/or sanction anticompetitive behavior in the payment card sector over the period 2004-2015. This results in a sample of 24 events, involving 135 listed banks operating in the EU-27 area. We run an event study analysis based on a traditional market model in order to estimate cumulated abnormal returns (CARs), considering both the date when the formal investigation is open and the date when the outcome of the procedure is communicated to the market. Our findings provide weak evidence in favor of the effectiveness of market discipline, with a significant (negative) market reaction only for investigations involving a small number of well-identified banking institutions, while procedures involving large banking associations or payment networks do not generate any relevant reaction.

    by Antonio Gledson De Carvalho, Joao Amaro De Matos, Douglas Pinheiro 
    Abstract: We model price stabilization in IPOs as a sequential decision: syndicate short position (SSP); occurrence of aftermarket short covering (ASC); and intensity of the ASC. We provide empirical evidence that corroborates its predictions. Our analysis is possible because in Brazil underwriters must disclose information on price stabilization. We innovate by simultaneously modeling the three different decisions. Our model predicts, and empirical results confirm, that the three decisions have distinct determinants: ex-ante demand is the only factor affecting the SSP, and ASC and its intensity increases with the riskiness of the issue, the ex-ante demand, and the underwriters reputation. Our model also innovates by considering the underwriters reputation.

  • Impact of Intellectual Capital on Bank Efficiency in Emerging Markets: Evidence from Ghana   Order a copy of this article
    by Joseph Mensah Onumah, King Carl Tornam Duho 
    Abstract: Various researchers have examined the relationship between intellectual capital (IC) and performance of banks. Yet, only few studies have examined the nexus between IC and bank efficiency especially in Africa. Using the VAIC model of Pulic (2000) (and its additive components Human Capital Efficiency (HCE), Structural Capital Efficiency (SCE) and Capital Employed Efficiency (CEE)) to measure IC and Data Envelopment Analysis to estimate efficiency scores, the current study used Ghanaian data of 32 banks from 2000 to 2015 to examine the nexus. The study found that risk-adjusted efficiency scores are higher than non-risk adjusted scores. There is evidence suggesting that IC instigates efficiency in banks. This is borne largely from HCE suggesting the prevalence of the human capital theory. The results of the impact of SCE and CEE are insignificant except for the significant positive impact of CEE on profit efficiency. Stock exchange listing increases efficiency scores especially risk-adjusted efficiency. Other exogenous variables such as size, leverage and concentration were controlled for with the results discussed into detail. The results have implications for bank regulation, bank management and future research.

  • Bank diversification and entrepreneurship: Evidence across US states   Order a copy of this article
    by Amit Ghosh 
    Abstract: Although a sizeable literature has examined the impact of income diversification on risk and return, the implication of banks diversification on entrepreneurial activities has not yet been studied. Using state-level data for the US spanning the period 1977-2014, the present study examines the impact of banks asset, income and funding diversification on different facets of entrepreneurial activities. We find banks asset and funding diversification to promote net business formation and net job creation. Additionally, bank profitability, deposit growth, as well as state-level personal income and housing price growth foster entrepreneurship.

  • Assessing the Long-Term Impact of Reforms and Privatization on the Banking Industry of Pakistan   Order a copy of this article
    by Yaseen Ghulam 
    Abstract: This study examines the long-term impact of privatization and broader reforms of the banking industry in Pakistan over a quarter of a century. We conclude that following the reforms and changes of ownership, as expected, banking firms made an adjustment to their input usage by switching from labour saving to labour using after the reforms, but vice versa for purchased funds. Simple descriptive statistics of the productivity estimates reveal that banking firms did not experience any improvement in productivity (medium-sized and private firms in particular). Operating nationwide has a clear advantage in terms of productivity growth compared, with operating only in urban centres with a limited number of branches. More importantly, when the productivity estimates are regressed on a number of explanatory variables to control for bank-specific factors and the economic, financial, industrial and political environment, we conclude that the reforms and changes of ownership have indeed made privatized banking firms in particular more productive.

  • Pricing 'partial-average' Asian options with the binomial method   Order a copy of this article
    by Erwinna Chendra, Kuntjoro Adji Sidarto, Muhammad Syamsuddin, Dila Puspita 
    Abstract: An Asian option is path-dependent derivatives whose payoff depends on the average of the underlying asset price over a certain pre-specified period of time. There is no simple closed-form solution for arithmetic Asian option hence the development of efficient and accurate numerical methods has become critical. In this paper, a modified binomial method is presented for pricing a more common arithmetic Asian option, by averaging the asset between two time periods in the life span of the option. This option is called the 'partial-average' Asian option. Subsequently, the representative averages are used instead of the actual ones for pricing the option. The set of representative averages is constructed first by determining the maximum and the minimum averages, where other averages are calculated by dividing equally the distance between the maximum and the minimum averages. For Asian option with average strike, if the distance between two time periods is widened by shifting the second time period to the right then the price becomes lower. But if the distance is widened by shifting the first time period to the left then the price becomes higher. The algorithm is not only simple but also easy to implement.
    Keywords: Asian option; partial-average; binomial method.

  • Determinants of CSR disclosure in Mexico   Order a copy of this article
    by Claudia Arena, Yanira Petrides, Petros Vourvachis 
    Abstract: This paper investigates Corporate Social (and environmental) Responsibility (CSR) disclosure practices in Mexico. It utilises a detailed manual content analysis and identifies corporate governance related determinants of CSR disclosure. The study shows a general association between the governance variables and both the content and the semantic properties of CSR information published by Mexican companies. Whilst an increased international influence on CSR disclosure is noted, the study particularly reveals the symbolic role of CSR committees and the negative influence of foreign ownership on community disclosure, suggesting improvements in business engagement with stakeholders are needed for CSR to be instrumental in business conduct.
    Keywords: Corporate Social Responsibility (CSR); CSR disclosure; disclosure determinants; Mexico; corporate governance; legitimacy theory; stakeholder engagement; content analysis.

  • Did removing prudence from the Conceptual Framework impact accounting conservatism?   Order a copy of this article
    by Elaine Conway 
    Abstract: The International Accounting Standards Board (IASB) removed explicit reference to the concept of prudence within the Conceptual Framework (CF) with effect from September 2010. This paper examines whether practitioner concerns that the removal of prudence might lead to a decrease in accounting conservatism and an increase in earnings management or overstated results were justified. It takes a sample of firms from the UK FTSE350, Australian ASX 300 and the South African JALSH (Johannesburg All Share) and evaluates three popular measures of accounting conservatism over the fourteen-year period of 2003-2016 (seven years pre and post the removal of prudence from the CF). The measures of accounting conservatism used were asymmetric timeliness of earnings, market-to-book ratio and total/non-operating accruals. Using all three measures, there was no evidence that the level of accounting conservatism has reduced during the period following the removal of prudence in the CF in those countries using IFRS. Despite this, the debate around prudence has continued and the IASB has since decided to reinstate it in the 2018 revised CF, effective 1 January 2020.

  • The effect of government involvement and payment method on merger and acquisition performance: the case of China   Order a copy of this article
    by Matthias Nnadi 
    Abstract: This paper applies a sample of 842 to investigate the effect of government involvement and payment methods on merger and acquisition of Chinese listed firms for the period 1993 - 2015. The study employs market model as benchmark to estimate expected returns for several event windows. We find that Chinese acquirer shareholders experience higher returns from the acquisitions in firms with no government involvements than those where government is involved. Our study demonstrates that stock-financed acquisitions maximise the wealth gains of shareholders than cash-backed acquisitions. Our finding further shows that using cash to finance government backed acquisitions yields extra wealth for investors on the announcement date whilst the market experience higher abnormal returns when stocks are used to finance the acquisition of privately held targets. The result of this paper has significant policy implications for both M&A financing decisions and government involvements in merger deals.

  • The WTI/Brent oil futures price differential and the globalisation-regionalisation hypothesis   Order a copy of this article
    by Michail Filippidis, Renatas Kizys, George Filis, Christos Floros 
    Abstract: This study examines the globalisation-regionalisation hypothesis in the WTI/Brent crude oil futures price differential by considering a set of potential crude oil-market specific and oil futures market specific determinants at 1, 3 and 6 months to maturity contracts. We employ monthly data over the period 1993:1-2016:12. Our results show that different determinants explain the spread between the WTI and Brent futures prices at different maturities. In the shorter-run maturities (1-month and 3-month) we find that spreads of the convenience yield, oil production, open interest and trading volume exercise significant effects in the WTI/Brent futures price differential. By contrast, for longer-run maturities (6-month), spreads of the oil production, oil consumption and open interest seem to exercise the most significant effects. We further provide evidence of a regionalised oil futures market over the short-run. The findings of this study provide valuable information to energy investors, traders and hedgers.

  • Reaction of EU stock markets to ECB policy interventions   Order a copy of this article
    by Dimitrios I. Vortelinos, Konstantinos Gkillas 
    Abstract: This paper investigates the significance and impact of ECB policy interventions on European stock markets. We conducted an event study and a regression analysis. Our data is drawn from the stock indices of the countries of all 28 members of the European Union (Euro members and non-euro members). Our dataset begins on 1 January 2001 and ends on 31 December 2014, for a total of 3,906 trading days. During the sample period, 394 policy interventions are considered as significant dates. Our results provide strong evidence in favour of a positive and statistically significant reaction to most of the ECB's policy interventions. The most important category of events is the financial sector (FSE).

  • Forecasting the daily dynamic hedge ratios in emerging European stock futures markets: evidence from GARCH models   Order a copy of this article
    by Taufiq Choudhry, Mohammad Hasan, Yuanyuan Zhang 
    Abstract: This paper empirically estimates and forecasts the hedge ratios of three emerging European and one developed stock futures markets by means of seven different versions of GARCH model. The seven GARCH models applied are bivariate GARCH, GARCH-ECM, BEKK GARCH, GARCH-DCC, GARCH-X, GARCH-GJR and GARCH-JUMP. Daily data during January 2000-July 2014 from Greece, Hungary, Poland and the UK are applied. Forecast errors based on these four stock futures portfolio return forecasts (based on forecasted hedge ratios) are employed to evaluate out-of-sample forecasting ability of the seven GARCH models. The comparison is done by means of model confidence set (MCS) and modified Diebold-Mariano tests. Forecasts are conducted over two non-overlapping out-of-sample periods, a two-year period and a one-year period. MCS results indicate that the GARCH model provides the most accurate forecasts in five cases, while each of the GARCH-ECM, GARCH-X and GARCH-GJR models constitutes model confidence set in four cases at a reasonable confidence level. Models selection based on modified Diebold-Mariano tests further corroborate results of the MCS tests. Differences between the portfolio returns also indicate the high forecasting ability of GARCH-BEKK and GARCH-GJR models.
