We consider a retailer selling a fixed inventory of two perishable products over a finite horizon. The products are sold individually or as part of a bundle. The customers arrive following a Poisson Process and each customer makes a purchasing decision based on her reservation prices of individual products: she either buys one of the individual products, buys the bundle or leaves without a purc...

In natural product synthesis, the procurement of easily accessible starting materials is crucial. Chromenones and their subclass, coumarins, are a wide family small, oxygen-containing aromatic heterocycles. Phenylcoumarins offer particularly excellent point for diverse chemical space products, thus staring more complex products. Herein, we report an efficient synthesis 3-phenylcoumarin bearing ...

In recent years trade with highly perishable agricultural products like fresh fish, berries, and cut flowers has increased substantially. The perishability of these appears to challenge conventional wisdom when it comes food trade, which emphasizes the importance large shipments reduce transportation costs. this paper, gravity models several margins are estimated for salmon, a product. results ...

We study inventorymanagement problemswhere demands are revealed incrementally and procurement decisionsmust bemade before the demands are realized. There are no probabilistic distributions nor nontrivial bounds to characterize demands. We consider two cost minimization problems: (1) perishable products with lost sales and (2) durable products with backlogged demand. In both problems, costs are ...

A retailer is endowed with a finite inventory of a non-perishable product. Demand for this product is driven by a price-sensitive Poisson process that depends on an unknown parameter, θ; a proxy for the market size. If θ is high then the retailer can take advantage of a large market charging premium prices, but if θ is small then price markdowns can be applied to encourage sales. The retailer h...

When customers for a product from N substitutable alternatives find their first choice sold out, they might “spill” to their second-most preferred products. The existing literature typically assumes an exogenous spill rate. We develop a surprisingly simple model that links the spill rate to economic factors associated with direct demand systems.
