With the development of Internet and expansion online to offline delivery services, takeaway food becomes a part consumption. This paper examined difference between dine-in take-out with carbon footprint waste among 346 people in Jiangsu Province, China, by using questionnaire figure out how much they may daily meals. Three aspects were researched questionnaire: classification, quantity food, p...

We propose a new measure capturing three dimensions of trading restriction tightness: trading quantity, speed, and cost. By using this new measure, we document a positive effect of restriction tightness on illiquidity discounts of restricted shares relative to their liquid counterparts, inferred from Division Reform, a market-level process of releasing trading restrictions in China Stock Market...

Certain purchasing groups do not flourish. A supposed reason for this is a creeping dissatisfaction among various members of a group with the allocation of the cooperative gains. In this paper, we analyze unfairness resulting from using the commonly used Equal Price (EP) method for allocating gains under the assumption of continuous quantity discounts. We demonstrate that this unfairness is cau...

We implement a simple two-shop search model in the laboratory with the aim to investigate if consumers behave differently in equivalent situations, where prices are displayed either as net prices or as gross prices with discounts . We compare treatments, where we either depict the known price of the first shop or the initially uncertain price of the second shop as a gross price with a discount,...

This paper applied a mixed integer programming approach to solve the sourcing and order allocation problem with multiple products and multiple suppliers in a supply chain. The decision process is driven bymultiple objectives and a set of constraints. Two schemes of quantity discounts are used to compare the influence upon the buying decisions. An example and an experimental test are presented t...

The problem of allocation of orders for custom parts among suppliers in make to order manufacturing is formulated as a singleor multi-objective mixed integer program. Given a set of customer orders for products, the decision maker needs to decide fromwhich supplier to purchase custom parts required for each customer order. The selection of suppliers is based on price and quality of purchased pa...

The standard monopoly pricing problem is re-considered when the buyer can disclose his type (e.g. age, income, experience) at some cost. In the optimal sales mechanism with costly disclosure, the seller posts a price list, including a “sticker price” available to any buyer and a schedule of discounts available to those who disclose certain types. Unambiguous welfare implications of such a prici...

We investigate the empirical behavior of ngram discounts within and across domains. When a language model is trained and evaluated on two corpora from exactly the same domain, discounts are roughly constant, matching the assumptions of modified Kneser-Ney LMs. However, when training and test corpora diverge, the empirical discount grows essentially as a linear function of the n-gram count. We a...
