H should the excess profit because of inventory pooling be shared amongst firms at different levels along the supply chain? Suppose each of several retailers observes local demand for a common item and places an order at the supplier, which is immediately filled if the supplier has the item in stock. The supplier can fill retailer orders either from their reserved inventories or from a shareabl...

in standard discussions (capitalistic economy), business firms and the income distribution property of production factors are dealt with in a manner in which they are independent from each other. and there is no interaction as such between them. furthermore, no role whatsoever is assumed for externalities. if we accept that there is interaction between production factors, and these 1actors, bec...

This paper provides efficient solutions to maximize profit for commercial ridesharing services, under a pricing model with detour-based discounts for passengers. We propose greedy heuristics for real-time ride matching that offer different trade-offs between optimality and speed. Simulations on New York City (NYC) taxi trip data show that our heuristics are up to 90% optimal and 10 times faster...

Quality loss functions have found widespread application in production engineering and today are an indispensable part of quality management. However, they share an obstacle with most other quality concepts concerning their limited communicability to top management. In the allocation of financial resources, a company’s executive board is commonly interested in the profit implications of competi...

We study a problem involving a set of organizations. Each organization has its own pool of clients who either supply or demand one unit of an indivisible product. Knowing the profit induced by each buyer/seller pair, an organization’s task is to conduct such transactions within its database of clients in order to maximize the amount of the transactions. Inter-organizations transactions are allo...

Does International Outsourcing Really Lower Workers’ Income? We analyze the impact of international outsourcing on income, if the domestic labor market is imperfect. We distinguish in our analysis between the case where the parties negotiate over the wage only and where they negotiate over both wage and profit share. We find that in the first case outsourcing will reduce (increase) workers’ inc...

According to the existing literature, capital taxes should not be imposed in the presence of optimal profit taxation in either unionised or competitive labour markets. We show that this conclusion does not hold for an economy with dual labour markets, where the competitive wage rate provides the outside option for unionised workers. Even with non-distortionary profit taxation it is optimal for ...

Itemset share has been proposed as a measure of the importance of itemsets for mining association rules. The value of the itemset share can provide useful information such as total profit or total customer purchased quantity associated with an itemset in database. The discovery of share-frequent itemsets does not have the downward closure property. Existing algorithms for discovering share-freq...
