Inventory control and intermediation in global supply chains

Zhan, Qu; Raff, Horst; Schmitt, Nicolas - 2015

The paper develops a simple theoretical model of inventory control in global supply chains. It identifies a role for intermediaries in managing inventory, and shows that inserting an intermediary as an additional link in a supply chain is profitable when demand volatility is high. It also...

Incentives through inventory control in supply chains

Zhan, Qu; Raff, Horst; Schmitt, Nicolas - 2017

The paper shows that taking inventory control out of the hands of competitive or exclusive retailers and assigning it to a manufacturer increases the value of a supply chain especially for goods whose demand is highly volatile. This is because doing so solves incentive distortions that arise...

Inventory, sourcing, and the effects of trade costs : theory and empirical evidence

Muris, Chris; Raff, Horst; Schmitt, Nicolas; Stähler, Frank - 2023

We develop a dynamic model of inventory investment and trade to examine how firms adjust to changes in international trade costs when facing a risk of stockouts due to demand uncertainty and order lead times for imports. We study two strategies firms may use to avoid stockouts, namely holding...

Airline schedule buffers and flight delays : a discrete model

Brueckner, Jan K.; Czerny, Achim Ingo; Gaggero, Alberto A. - 2020 - Version of August, 2020

This paper revisits the airline schedule-buffer choice problem analyzed by Brueckner, Czerny and Gaggero (2020) using a simpler model where the random shocks influencing flight times are discrete rather than continuous. The analysis yields closed-form solutions for the flight and ground buffers...

Prices, schedules, and passenger welfare in multi-service transportation systems

Billette de Villemeur, Étienne; Vinella, Annalisa - 2019

We consider a multi-service transportation system in which passengers are heterogeneous along two dimensions, namely ideal departure time and value of time, leading to both horizontal and vertical differentiation. We investigate the behavior of passengers, and assess how service pricing and...

Dispatching after producing : the supply of non-renewable resources

Daubanes, Julien; Lasserre, Pierre - 2014

We examine the impact of uncertainty on employment dynamics. Alternative measures of uncertainty are constructed based on the survey of professional forecasters, and regression-based forecasting models for GDP growth, inflation, S&P500 stock price index, and fuel prices. Our results indicate...
