When using daily mutual fund returns to study market timing ability, heavy tails and heteroscedasticity significantly challenge the existing methods. We propose a weighted nonparametric measure and test for market timing. The test finds that the traditional parametric inference misclassifies...

We document statistically significant relations between fund beta and past market returns that affect standard estimates of mutual fund market timing. Our evidence of “artificial” market timing emerges when we estimate market timing regressions across time periods that span time variation in...

When using daily mutual fund returns to study the market timing, heavy tails and heteroscedasticity significantly challenge the existing methods. We to accommodate them, we propose a new measure and an efficient test for market timing ability and find that the traditional test misclassifies...

Auto-delivery is a subscription model widely employed in supply chains, whereby a supplier delivers products to a buyer (or multiple buyers) according to the buyer's choice of a constant shipping quantity to be delivered at prescheduled dates. The buyer enjoys a discount for the auto-delivery...

Cloud computing has been recognized as a critical driver of Information-Technology (IT) enabled innovations. In this paper, we review recent cloud computing research from an Operations Management (OM) perspective, by focusing on major operations challenges faced by a cloud provider in three...

This paper provides statistical learning techniques for determining the full own-price market impact and the relevance and effect of cross-price and cross-asset spillover channels from intraday transactions data. The novel tools allow extracting comprehensive information contained in the limit...

In recent years, there has been an increasing trend in supply chains to employ a “control tower” approach to improve supply chain performance. Such a strategy includes vendor- or supplier-managed-inventory (VMI or SMI) where the supplier takes over the control tower, and the other strategy...

This paper provides statistical learning techniques for determining the full own-price market impact and the relevance and effect of cross-price and cross-asset spillover channels from intraday transactions data. The novel tools allow extracting comprehensive information contained in the limit...

Rapid growth in the cloud services market provides tremendous opportunities to cloud providers who have invested heavily in computing capacities but also has led, at time, to low utilization of capacities. To alleviate this problem, some providers have launched a low-priority service with...
