This paper presents a capacitated lot-sizing problem in flow-shop system with energy consideration. The planning horizon is defined by a set of periods. Each period is characterized by demand, duration, electricity cost and maximum peak power. Both non-linear and linear mixed integer programming are proposed to solve the problem with the objective of minimizing the production costs. The costs a...

Network Competition with Heterogeneous Calling Patterns by Wouter Dessein We show how differences in demand and unbalanced call flows affect considerably the pricing strategies of competing telecommunications networks and this both for competition in linear and nonlinear pricing. Differences in demand give also scope for targeted entry. If networks are close substitutes, we show that an incumbe...

This paper presents an oligopoly model of multiproduct firms in which firms are endowed with possibly different marginal cost and product quality, and choose product ranges before product market competition. Consistent with empirical evidence on a positive relationship between firm size and product diversification, the analysis suggests that firms with higher quality-cost margins typically have...

This paper generalizes the evolutionary cobweb model with heterogeneous beliefs of Brock and Hommes (1997. Econometrica 65, 1059}1095), to the case of non-linear demand and supply. Agents choose between a simple, freely available prediction strategy such as naive expectations and a sophisticated, costly prediction strategy such as rational expectations, and update their beliefs according to an ...

In this paper, we examine the consequences of demand-function heterogeneity for the estimation of the consumer surplus. In particular, we show that, given a linear demand function with random coefficients, one can consistently estimate the consumer surplus distribution without making parametric assumptions about the coefficient distribution. The approach is illustrated using data on gasoline co...

The objective of this model is to investigate the inventory system for perishable items with linear demand pattern where Weibull deterioration is considered. The Economic order quantity is determined for minimizing the average total cost per unit time. The unit production cost is taken to be inversely related to the demand rate. The result is illustrated with numerical example.

Starting from a linear error correction model (ECM) the stability and linearity of a German M1 money demand function are investigated, applying smooth transition regression techniques. Using seasonally unadjusted quarterly data from 1961(1) to 1990(2) it is found that the money demand equation considered is both linear and stable. After extending the sampling period until 1995(4) a clear struct...

We determine empirically how the Big Three automakers accommodate shocks to demand. They have the capability to change prices, alter labor inputs through temporary layoffs and overtime, or adjust inventories. These adjustments are interrelated, non-convex, and dynamic in nature. Combining weekly plant-level data on production schedules and output with monthly data on sales and transaction price...

In this paper, we present a robust optimization formulation for dealing with demand uncertaintyin a dynamic pricing and inventory control problem for a make-to-stock manufacturing system. Weconsider a multi-product capacitated, dynamic setting. We introduce a demand-based fluid modelwhere the demand is a linear function of the price, the inventory cost is linear, the production ...

India has been running large-scale interventions in the energy sector over the last decades. Still, there is a dearth of reliable and readily available price and income elasticities of demand to base these on, especially for domestic use of traditional fuels. This study uses the linear approximate almost ideal demand system (LA-AIDS) using micro data of more than 100,000 households sampled acro...
