The impact of the global financial crisis on the cross-currency linkage of LIBOR–OIS spreads

This article examines the impact of global financial crisis on cross-currency linkage of the LIBOR–OIS spread, a financial stress measure in interbank markets. The impulse response analysis is conducted in a multivariate setting, adopting the bias-corrected bootstrap as a means of statistical inference. The overall evidence suggests that the crisis has substantially changed the nature of the cross-currency interactions in liquidity stress. Also global money markets have failed to contain stress in US dollar funding and the role of the Japanese yen as a liquidity source appears to be significant, while these two currencies drive the cross-currency system of liquidity stress.     

Can ambiguity aversion solve the equity premium puzzle? Survey evidence from international data

Ambiguity aversion has been suggested as a potential explanation for the equity premium puzzle in recent theoretical models. To test this hypothesis, we measure the amount of ambiguity aversion in a large-scale international survey. A comparison to the average equity premia in these countries demonstrates that ambiguity aversion does, indeed, have a significant influence on the amount of equity risk premium, even when controlling for macroeconomic parameters. Finally, we connect differences in ambiguity aversion to differences in uncertainty avoidance, one of Hofstede’s cultural dimensions.     

Time-varying betas and the cross-sectional return–risk relation: evidence from the UK

The seminal study by Fama and MacBeth in 1973 initiated a stream of papers testing for the cross-sectional relation between return and risk. The debate as to whether beta is a valid measure of risk was reanimated by Fama and French and subsequent studies. Rather than focusing on exogenous variables that have a larger explanatory power than an asset's beta in cross-sectional tests, the matrix of variances-covariances is assumed to follow a time varying ARCH process. Using monthly data from the UK market from February 1975 to December 1996, the cross-sectional return–risk relations obtained with an unconditional specification for assets’ betas are compared to those obtained when the estimated betas are based on an ARCH model. The approach taken by Pettengill, Sundaram and Mathur, which allows a negative cross sectional return–risk relation in periods in which the market portfolio yields a negative return relative to the risk free rate, was also investigated. These tests are also carried out on samples pertaining to a specific month and on samples from which a particular month is removed. Results suggest that the CAPM holds better in downward moving markets than in upward moving markets hence beta is a more appropriate measure of risk in bear markets.     

Does sovereign risk matter? New evidence from eurozone corporate bond ratings and zero-volatility spreads

In this paper, we empirically examine if sovereign risk matters for corporate bonds in developed economies. Using a unique panel data sample of 897 corporate bonds from eleven countries within the Economic and Monetary Union (EMU), we investigate sovereign and corporate ratings as well as zero-volatility spreads (z-spreads). In the time period from March 2006 to June 2012, we find sovereign risk to be a significant driver of corporate risk. The effect is stronger for companies with domestic revenue structure, for companies that are (partly) owned by the government, and companies active in the utility and transportation sector. Interestingly, the impact of sovereign risk on corporate risk during the acute European sovereign debt crisis period decreases if ratings are examined, but increases if z-spreads are utilized. Rating agencies seem to take a more differentiated view on individual company risk during the sovereign debt crisis, while institutional investors might want to reduce their exposure to a country in financial distress as a whole, regardless of whether sovereign or corporate bonds are held.     

The impact of a new term auction facility on Libor–OIS spreads and volatility transmission between money and mortgage markets during the subprime crisis

During the subprime crisis, the U.S. Federal Reserve was concerned about widening spreads between overnight interbank lending rates such as the overnight index swap (OIS) and term London Interbank Offer Rate (Libor). Among the tools it used to counter the impact of the crisis, the innovative term auction facility (TAF) attracted much attention. We investigate the impact of the TAF on the Libor–OIS spread. We find that the TAF has clear initial and sustained expectation effects on the three-month Libor–OIS spread, but no real initial or short-term funding effects, which casts doubt on the usefulness of the TAF in reducing risk spreads. Since the subprime crisis also spilled across the interbank, commercial paper, and jumbo mortgage markets, we further examine the lead–lag relation between Libor–OIS, commercial paper, and jumbo spreads and the volatility transmission effects between them. For the period before the crisis, we find that the three markets behave largely independently. For the subprime crisis period, however, we find multidirectional lead–lag relations and one-way volatility transmission between these markets.     

Euro money market spreads during the 2007–? financial crisis

In the paper we investigate the empirical features of euro area money market turbulence during the recent financial crisis. By means of a novel Fractionally Integrated Heteroskedastic Factor Vector Autoregressive model, we find evidence of a deterministic level factor in the EURIBOR-OIS (OIS) spreads term structure, associated with the two waves of stress in the interbank market, following the BNP Paribas (9 August 2007) and Lehman Brothers (16 September 2008) “shocks”, and two additional factors, of the long memory type, bearing the interpretation of curvature and slope factors, respectively. The unfolding of the crisis yields a significant increase in their persistence and volatility. We also find evidence of a declining trend in the level and volatility of OIS spreads since December 2008, associated with ECB liquidity policies.     

Statistical arbitrage in the Black–Scholes framework

In this study, we prove the existence of statistical arbitrage opportunities in the Black–Scholes framework by considering trading strategies that consist of borrowing at the risk-free rate and taking a long position in the stock until it hits a deterministic barrier level. We derive analytical formulas for the expected value, variance and probability of loss for the discounted cumulative trading profits. The statistical arbitrage condition is derived in the Black–Scholes framework, which imposes a constraint on the Sharpe ratio of the stock. Furthermore, we verify our theoretical results via extensive Monte Carlo simulations.     

The concentration–stability controversy in banking: New evidence from the EU-25

This study explores whether the concentration–stability relation is affected by the level of analysis; i.e., bank-level versus country-level stability. The diverging results in the literature suggest that we may indeed expect differences between the two levels. With the z-score as the measure of financial stability, our theoretical analysis confirms that we may find such differences. Yet our empirical analysis for the EU-25 during the 1998–2014 period finds no economically significant effect of concentration on either the bank-level or the country-level z-score. The finding that concentration hardly affects stability at both levels of analysis is an indication of robustness in the empirical concentration–stability relation not previously established in the literature. This finding further suggests that neither supervisory restructuring, nor normal market-driven mergers, are likely to be substantially harmful to financial stability.     

Do liquidity or credit effects explain the behavior of the BKBM–LIBOR differential?

This paper examines the evolution of the relationship between the onshore and offshore benchmarks for New Zealand dollar funding during the global financial crisis. In August 2007 the BKBM–LIBOR differential switched from positive to negative and then widened considerably following the collapse of Lehman Brothers in September 2008, before narrowing gradually as the turmoil in financial markets subsided. Our structural regression model and decomposition analyses show that changes in liquidity, proxied by bid/ask spreads, largely explain the changes in the BKBM–LIBOR differential over this period and that credit risk factors only played a minor role. However our analysis also shows that bid/ask spreads in the offshore market price information regarding counterparty credit risk, suggesting that our initial results could understate the role played by credit risk factors.     

Which bank is the “central” bank?

Liquidity flows through a financial network cannot be accurately described using external processing constraints alone. Behavioral aspects of participants also matter. A method similar to Google's PageRank procedure is used to produce a ranking of participants in the Canadian Large Value Transfer System in terms of their daily liquidity holdings. Accounting for differences in banks’ processing speeds is essential for explaining why observed distributions of liquidity differ from the initial distributions, which are determined by the credit limits selected by banks. Delay tendencies of banks are unobservable in the data and are estimated using a Markov model.     

Superconvergence of the finite element solutions of the Black–Scholes equation

We investigate the performances of the finite element method in solving the Black–Scholes option pricing model. Such an analysis highlights that, if the finite element method is carried out properly, then the solutions obtained are superconvergent at the boundaries of the finite elements. In particular, this is shown to happen for quadratic and cubic finite elements, and for the pricing of European vanilla and barrier options. To the best of our knowledge, lattice-based approximations of the Black–Scholes model that exhibit nodal superconvergence have never been observed so far, and are somehow unexpected, as the solutions of the associated partial differential problems have various kinds of irregularities.     

Value Based Management practices—some evidence from the field

Value Based Management (VBM), and especially Economic Value Added (EVA™),¹ has attracted considerable interest among organisations in recent years. These concepts can be applied to capital budgeting, valuation, management control, and incentive compensation. Despite the growing number of applications, we have only limited independent research-based evidence on how these concepts are actually applied. However, this can be considered not only an essential step in research investigating the benefits of VBM [cf. Ittner, C.D., Larcker, D.F.,1998. Innovations in performance measurement: trends and research implications. Manage. Acc. Res. 10, 205–238], but also on its limitations. With the aid of six Finnish-based organisations from five different industries, we illustrate the diversity of actual use of VBM. Our results indicate that for some organisations VBM is merely rhetoric, while for others it seems to have an impact on both decision making and control system, taking various forms from one firm to another. In some organisations, application of VBM is restricted only to the highest levels of hierarchy, whereas in others it covers the whole organisation. However, in none of the studied organisations is VBM applied in as comprehensive a manner as suggested in the normative literature. This multitude of different ways in which VBM is actually used in practice raises some problems regarding the study of VBM and its benefits. In particular, the adoption of EVA™, as measured with EVA™ based bonuses [see e.g. Wallace, J.S., 1997. Adopting residual income-based compensation plans: do you get what you pay for? J. Acc. Econ. 24, 275–300; Kleiman, R., 1999. Some evidence on EVA companies. J. Appl. Corp. Finance 12, 80–91], is seriously challenged.     

Output–employment relationship across employment status: evidence from Turkey

This paper investigates output–employment relationships across different employment statuses and formal versus informal employment divisions for Turkey. Even if we fail to find a long-run relationship between aggregate output and total employment, there are long-run relationships between the aggregate output with all of the formal employment statuses. A further investigation for short-run relationships reveals no statistically significant relationships between aggregate output and total employment and between aggregate output and casual employment but there is a significant short-run relationship between aggregate output and total regular employment. Thus, a sustainable economic growth policy should aim to create formal and regular employment.     

A potential benefit of increasing book–tax conformity: evidence from the reduction in audit fees

Our study explores a possible benefit of conforming book income to taxable income. We expect that increased book–tax conformity can reduce audit fees by simplifying tax accruals and increasing tax authorities’ monitoring, which reduce audit workload and audit risk, respectively. Consistent with our expectations, we find that a higher country level of required book–tax conformity leads to lower audit fees. Moreover, firm-level book–tax differences are positively associated with audit fees. We also find that the negative association between country level of required book–tax conformity and audit fees is mitigated among firms with larger book–tax differences. Our findings are robust to including country-level legal investor protection or other extra-legal institutions. Overall, our results suggest that one benefit of increasing book–tax conformity is the reduction in audit fees.     

(Unusual) weather and stock returns—I am not in the mood for mood: further evidence from international markets

This paper investigates the explanatory power of weather variables deviations in two leading international financial trading centres (New York and London) on 58 global stock indices over the period September 2000 to December 2013. The empirical results find that unusual deviations of weather variables from their monthly averages have a statistically significant effect on stock returns across global returns. The paper also attempts to explain these effects through the sales and energy prices mechanisms. The results provide strong support to both mechanisms.     

Comparison of Black–Scholes Formula with Fractional Black–Scholes Formula in the Foreign Exchange Option Market with Changing Volatility

In this paper, the authors discuss the fractional option pricing with Black–Scholes formula, deduce the Fractional Black–Scholes formula, show the empirical results by using China merchants bank foreign exchange call option price, and find when the volatility is smaller, the asymptotic mean squared error of Fractional Black–Scholes is bigger than the Traditional Black–Scholes’, while the volatility is bigger—the market mechanism has a full play, the result is reverse. Namely when the market mechanism is given a full scope, the estimating effect of Fractional Black–Scholes is better than Traditional Black–Scholes’.     

The determinants of audit fees—evidence from the voluntary sector

Given the growing demand for accountability in the public sector, there is a need to begin to investigate audit pricing issues in this sector. This study makes three contributions. First, it develops and estimates, for the first time, a model of audit fee determinants for the charity sector. As in previous private sector company studies, size, organisational complexity and audit firm location are the major determinants. A positive association between audit fees and fees for non-audit services is also observed. Charity sector factors of empirical significance include the nature of the charity (i.e., grant-making or fund-raising), its area of activity and the importance of trading income. Separate models for grant-making and fund-raising charities reflect the relative complexity of the audit of fund-raising charities. Second, the lower auditor concentration in the charity sector market, compared to the private sector market, permits a more powerful test of whether large firms and/or auditor expertise are rewarded with a fee premium. In the more complex audit environment of fund-raising charities, the results show that Big Six audit firms receive higher audit fees (18.5%, on average) than non-Big Six firms. Also, non-Big Six audit firms with charity expertise are rewarded with a fee premium over other non-Big Six firms. Finally, the study demonstrates that the charity audit fee rate is significantly lower than that of private sector companies; in fact it is approximately half. A change in the reporting of charity audit fees is proposed to reflect any element of ‘charitable giving’ by the audit firm.     

Does the “Zurich consensus” provide grounds for cautious optimism?

It is now clear that the so-called “Washington consensus”, the obsession with markets and the studied refusal to engage with global problems, is dead. The month of November 2008 may be seen by future generations as a turning point in human civilisation. While the Club of Rome has been warning for decades of the consequences of unsustainable growth, organisations like the World Economic Forum and the International Energy Agency have until recently supported the old market-oriented approach that assumed economic growth would solve all our problems. Now the financial crisis has exploded that myth and triggered rethinking of basic assumptions. A new consensus is emerging that recognises biophysical limits and the interlocking social, economic and environmental challenges we face. This provides grounds for cautious optimism that we may be entering a period of social learning which will allow human civilisation to survive.
