Sediments in estuary areas are recognized as the ultimate reservoirs for numerous contaminants, e.g., toxic metals. Multivariate analyses by chemometric evaluation were performed to classify metal ions (Cu, Zn, As, Cr, Pb, Ni and Cd) in superficial sediments from Lingdingyang Bay and to...

At the same time of tending forests, it is necessary to explore the under-forest economic development mode, bring into play production function of economic plants, establish cultivation mode of edible fungus, wild vegetables and medicinal plants under forest, to obtain certain economic benefit...

This paper studies pricing and assortment management for cross-category products, a common practice in brick-and-mortar retailing and e-tailing. We investigate the complementarity effects between the main products and the secondary products, in addition to the substitution effects for products...

Problem definition: The joint assortment and pricing problem is notoriously challenging, especially with a large problem size and various operational constraints arising from business practices. In this paper, we consider the joint product offering and pricing under the constrained logit choice...

In this paper, we develop an integrated framework to study a firm's joint decisions on product price, quality and service duration in a variety of monopolistic and competitive scenarios. Product price, quality, and ancillary service (such as maintenance and factory warranty) are arguably among...

This paper incorporates heterogeneous threshold effects into the classical multinomial logit (MNL) model, and studies the associated operations problems such as estimation and assortment optimization. The derived model is referred to as the threshold multinomial logit (TMNL) model and...

Problem definition: This paper incorporates a piecewise linear structure into the utility-price relationship of the classic multinomial logit (MNL) model, and studies the associated operations problems such as estimation and pricing. The derived model is referred to as the piecewise MNL model...

We examine whether sizable initial public offerings (IPOs) affect the whole market. Using a Chinese IPO sample, we find robust evidence that sizable IPOs do depress the market price on not only the listing day but also the offering (subscription) day. The impact on the market is negatively...
