We analyze a supply chain environment in which a distributor facing price-sensitive demand has the opportunity to contractually commit to a delivery quantity at regular intervals over a finite horizon in exchange for a per-unit cost reduction for units acquired via committed delivery. Supplemental orders needed to meet demand are purchased at an additional unit cost. For normally distributed de...

CONTEXT In India, 14% of the population use smoked tobacco products. Increasing prices of these products is one of the measures to curb their consumption. AIMS This study analyzes "unit price" and "daily consumption" of cigarettes and bidis and investigates their relation with each other. SETTINGS AND DESIGN A cross-sectional survey was conducted in four states of India (Bihar, West Bengal,...

Given a commodity available at different prices, a unit-price account of choice predicts preference for the cheaper alternative. This experiment determined if rhesus monkeys preferred remifentanil (an ultra-short-acting micro-opioid agonist) delivered at a lower unit price over a higher-priced remifentanil alternative (Phases 1 and 3). Choice between equal-priced alternatives also was assessed ...

OBJECTIVES The rapid increase in drug expenditure has become a major source of public criticism in China. In 2009, the National Essential Medicine System (NEMS) was launched in China to control drug prices and improve access to medicines. This study investigated whether and to what extent the prices of essential medicines were reduced after the introduction of NEMS. METHODS Data were obtained...

This study were estimated the contribution of carcass traits to unit price, to analyze the marbling score as a categorical variable rather than a numerical variable, and to develop an optimal model that also includes the holiday effect and the raising period. The data for this study were acquired from the Quality Evaluation of the Korea Institute for Animal Products, and consisted of the tradin...

Key pecking by 3 pigeons was maintained by a multiple fixed-ratio 10, fixed-ratio 30, fixed-ratio 90 schedule of food presentation. Components differed with respect to amount of reinforcement, such that the unit price was 10 responses per 1-s access to food. Acute administration of morphine, l-methadone, and cocaine dose-dependently decreased overall response rates in each of the components. Wh...

A multi item inventory model with demand dependent on unit price and leading time with limited storage space and set up cost is considered in this paper. The varying production and leading time crashing costs are considered to be continuous functions of unit price and leading time respectively. The model is solved using Karush Kuhn Tucker conditions approach with optimal order quantity, unit pr...

OBJECTIVE To determine the willingness to pay (WTP) and the benefit-cost of modern contraceptives delivered through the public sector in Nigeria. METHODS Data were collected from 4517 randomly selected households. The WTP for the 6 major contraceptive methods available in the public sector was elicited. Logistic regression was used to determine whether the decision to state a positive WTP amo...

Firms sometimes write price lists or catalogs for their exports, so they set prices for a period of time and do not adjust prices during that interval in response to changes in their environment. The firm sets the price either in its own currency or the importer’s currency. This paper draws a simple link between the choice of currency and the pricing decision of a firm that changes prices in re...

Traditionally, policymakers and financial markets have regarded the “core” consumer price index (CPI) as a key inflation indicator. The core CPI, a special index published by the Bureau of Labor Statistics (BLS), excludes the volatile prices of food and energy. In excluding these components, BLS recognizes that prices that swing dramatically in response to unusual shifts in weather and other un...
