This thesis presents a dynamic pricing model where a seller offers two types of a generic product to a random number of customers. Customers show up sequentially. When a customer arrives, he will ---depending on the prices---either purchase one unit of type 1 product or one unit of type 2 product, …

Analyticity as Expressive of Monotonic Material Inference
… of treating the inferences appropriately substitutable for 'x' as materially monotonic. This interpretation demands that only explicating inference expressions are appropriately considered analytic: a demand defended in this paper. Furthermore, it is demonstrated that this interpretation …

Supply Chain Design With Cross Sales, Product Design, and Price -Setting Competitive Newsvendors
… Consider two manufacturers, each producing a substitutable product and selling it through either a decentralized or an integrated retailer, which is modeled as a price-setting newsvendor. A multiplicative demand function incorporating a random factor &egr; is assumed. Results indicate the …

Welfare Impacts of Alternative Public Policies for Environmental Protection in Agriculture in an Open Economy: A General Equilibrium Framework
… that when land and nitrogen fertilizer are substitutable, retiring croplands may raise the demand for nitrogen and cause more nitrogen pollution. It also shows that taxing applied nitrogen may perform better than taxing nitrogen pollution in the presence of agricultural subsidies in an open …

Multi-period pricing for perishable products : uncertainty and competition
… products are assumed to be differentiated and substitutable. Each seller has the option to set prices for her products at each time period, and her goal is to find a pricing policy that will yield the maximum overall profit. Each seller has a fixed initial inventory of each product to be …

Capacity Investment, Flexibility, and Product Substitution/Complementarity under Demand Uncertainty
… a firm that produces two products, which can be substitutable or complementary. The demand of each product is a linear function of the prices of both products (with the relationship depending on the substitution/complementarity structure), and is subject to an additive stochastic shock. We …

Bootstrapping Structure into Language: Alignment-Based Learning
… Unequal parts of sen tences can be seen as being substitutable for each other, since substituting one unequal part for the other results in another valid sentence. The unequal parts of the sentences are thus considered to be possible (possibly overlapping) constituents, called hypotheses. Secondly …

A technological, economic and social exploration of phosphate recovery from centralised sewage treatment in a transitioning economy context
Phosphate is an important, non-substitutable nutrient for all life forms and is essential in ensuring universal food security. In the past, waste water treatment works (WWTW) typically installed effluent polishing technologies to eliminate phosphate and lower concentrations of both nitrogen and …
