This paper analyses coordination in a supply chain consisting of a supplier and a retailer, where the retailer has the opportunity to return products at midlife and end-of-life. The paper examines particularly the coordination problem when the supplier has the opportunity to realise a limited amount of overstock items at a higher price than the retailer at midlife. In this paper return options ...

We simulate a series of daily returns from intraday price movements initiated by microstructure elements. Significant evidence is found that daily returns and daily return volatility exhibit first order autocorrelation, but trading volume and daily return volatility are not correlated, while intraday volatility is. We also consider GARCH effects in daily return series and show that estimates us...

This paper empirically examines the relation between the expected stock return and the bid-ask spread. Using the same portfolio formation method as in Amihud and Mendelson (1986) but different test methodologies, we do not find any clear reliable relation between the CAPM risk-adjusted return and the relative bid-ask spread. Our empirical results are more consistent with the conclusions of Cons...
