Abstract In rational, efficiently functioning and complete markets, returns on derivative and underlying securities should be perfectly contemporaneously correlated. Due to market imperfections, one of these markets may reflect information faster. The use of high-frequency data and the choice for a small unit time interval to measure these lead-lag relations comes at the cost of some or many missing observations, causing traditional estimators to either under- or overestimate covariances and correlations. We use a new estimator to estimate lead-lag relationships between the cash AEX index, options and futures. We find that futures returns lead both options and cash index returns by approximately 10 minutes. The relationship between options and the cash market is not completely unidirectional.

This paper examines empirically the effects of domicile and SEC registration and reporting requirements on information asymmetry. We compare the adverse-selection component of the relative bid–ask spread (our measure of information asymmetry) for three samples of Nasdaq NMS companies that trade in different home markets and are subject to different standards of disclosure: registered U.S. companies, registered non-Canadian foreign companies, and unregistered non-Canadian foreign companies covered by the information-supplying exemption of the Securities and Exchange Act of 1934. We find that the adverse-selection component is not significantly larger for the two foreign samples, and it is not reliably different for the registered and unregistered foreign samples. Therefore, we are unable to document that less stringent SEC registration and reporting requirements for foreign companies are associated with greater information asymmetry among investors for non-U.S. securities traded on Nasdaq.

This paper provides empirical evidence on the economic value of services provided by independent auditors by analyzing whether auditor association leads to reduced interest rates on revolving credit agreements. Using multivariate regressions, we analyze the relation between interest rates on revolving bank loans to small, private firms and the degree of auditor association with the financial statements provided to the lender,

This paper surveys the empirical and theoretical literature on the mechanisms of corporate governance. We focus on the internal mechanisms of corporate governance (e.g., corporate board of directors) and their role in ameliorating various classes of agency problems arising from conflicts of interests between managers and equityholders, equityholders and creditors, and capital contributors and other stakeholders to the corporate firm. We also examine the substitution effect between internal mechanisms of corporate governance and external mechanisms, particularly markets for corporate control. Directions for future research are provided.

With a stochastic time change from calendar-time to information-time, we derive a parsimonious option pricing formula with stochastic volatility as a risk-neutral Poisson sum of Merton's (1973) prices over the option's information-time maturity domain. The formula contains two unobservable parameters, information arrival intensity and information-time asset volatility, with stochastic volatility induced by random information arrival. When the information arrival rate intensifies, the option price increases and vice-versa. We test the formula in pricing, hedging, and excess profits capture empirically using currency and the S&P 500 futures options transaction data.

Abstract This study tests the competitive equilibrium predictions of a multi-period model of audit pricing and independence in two sets of laboratory markets: a control set consisting of human subjects in the role of auditors contracting with robot clients, and a treatment set in which both auditors and clients are human subjects. The results in all the control-set markets and some of the treatment markets support the predictions of "lowball" pricing and that heterogeneous beliefs among auditors regarding the treatment of a client-reporting issue is a necessary condition for independence impairment. By contrast, several treatment-set markets exhibit cooperative behavior between auditors and clients to achieve jointly beneficial outcomes. This behavior deviates from the price-independence relationship predicted in the competitive equilibrium, exhibiting instead a price-independence relationship that is characterized by an absence of lowballing and frequent independence impairment, even when auditors have homogeneous beliefs.
