Abstract We examine international equity allocations at the fund level and show how excess foreign returns influence portfolio rebalancing, capital flows, currencies. Our equilibrium model of incomplete exchange (FX) risk trading where rate partially segments markets is consistent with observed dynamics returns, rates, fund-level flows. document that rebalancing more intense under higher FX vol...

In this paper we study the routing and rebalancing problem for a fleet of autonomous vehicles providing ondemand transportation within a congested urban road network (that is, a road network where traffic speed depends on vehicle density). We show that the congestion-free routing and rebalancing problem is NP-hard and provide a randomized algorithm which finds a low-congestion solution to the r...

The class imbalance problem in classification has been recognized as a significant research problem in recent years and a number of methods have been introduced to improve classification results. Rebalancing class distributions (such as over-sampling or under-sampling of learning datasets) has been popular due to its ease of implementation and relatively good performance. For the Support Vector...

Because of imbalanced spatial-temporal user demands, situations with no available bikes or docks often occur. In order to better response many researchers are devoted rebalancing bike sharing systems (BSS). Existing researches focus primarily on BSS by trucks workers individually, resulting in two issues: (a) the high cost and massive emissions associated trucks-based rebalancing; (b) low effic...
