We empirically investigate the impact of option listing on the underlying stock efficiency by looking at the volume-volatility relation of underlying stock. We use a time- consistent bivariate VAR (Vector Autoregressive Regression) model that includes time duration between trades. This model...

We empirically investigate the effect of option listing on the underlying stock pricing efficiency by examining the stock price duration dynamic. We use univariate tests and modified Log-ACD models that account for liquidity. Results indicate that option listing neither damages nor improves the...

We empirically investigated the impact of option listing on the underlying stock efficiency by looking at the volume-volatility relation. We use a time-consistent bivariate VAR (Vector Autoregressive Regression) model that accounts for time duration between trades. Post-listing and pre-listing...

This study investigates the informativeness of purchase price allocations (PPAs) that involve fair value estimation of acquired assets and liabilities after a business combination. Using a model capturing the amount of goodwill expected after the initial announcement of an acquisition, we...

For a number of decades now, at the instigation of Anglo-Saxon standard setters, the basis of the traditional accounting model, or the financial conventions which determine how a company’s wealth and income is measured, have been increasingly called into question. This wide-reaching movement,...

This article looks at the usefulness of measuring a company's wealth and net income using the fair value method. In this regard, the key question--is fair value relevant?--can be analysed as follows: do fair value "accounting numbers" provide a better estimate of the value of a company and the...

In this article, tests for globalization and contagion are separated using an ex ante definition of crises, and contagion tests are neutralized with respect to globalization effects. A large database is constructed to study the stability of correlation matrices for four asset classes : equities,...

In this study we set the problem of the probable existence of an additive and multiplicative mixed seasonality. In this context, we show by some simulation that the seasonality correction according to a pure additive or a pure multiplicative scheme leads to biased estimators of the coefficients...
