The paper compares the expected performance of a Vendor Managed Inventory (VMI) supply chain with a traditional “serially-linked” supply chain. The emphasis of this investigation is the impact these two alternative structures have on the “Bullwhip Effect” generated in the supply chain. We pay particular attention to the manufacturer’s production ordering activities via a simulation model based ...

Commonly used frictional models of the labor market imply that changes in frictions have large effects on steady state employment and unemployment. We use a model that features both frictions and an operative labor supply margin to examine the robustness of this feature to the inclusion of a empirically reasonable labor supply channel. The response of unemployment to changes in frictions is sim...

This article extends the analysis of the impact of a system of protein premiums and discounts to that on a farmer's planned production. Despite an unambiguously negative impact on expected pro¢ts of equally likely premiums and discounts, supply response to the introduction of such a system is shown to depend on the level of seasonal variability faced by the farmer. In particular, farmers in reg...

Since 2020, supply chain disruptions have emerged as an ever-present challenge. This research provides a glimpse into the organizational structures that develop resilience and market performance amid continuous disruptions. Utilizing psychosomatic variables empirical modeling, model was constructed through review of extant literature tested with PLS-SEM analysis. Uniquely, this is framed stimul...

1. In open loop, the velocity response depends on the mechanical time constant of the DC machine (time response) and the value of the power supply. Indeed, for each value of power supply, a velocity value is reached in steady state. Therefore the DC machine can reach any value of velocity which depends only of the power supply. In this case no possibility to improve performances. 2. For a speci...

As part of its growth strategy, Caterpillar Inc. plans to launch a new P2000 product line of \compact" construction equipment and work tools. In anticipation of this, they asked the authors to construct and analyze potential P2000 supply chain con gurations. Through the use of decomposition, and results from network ow theory, inventory theory, and simulation theory, we were able to provide a s...

Keithley’s Series 2300 Battery/Charger Simulators (fast transient response power supplies) are specifically designed for powering RFIC power amplifiers, mobile phone handsets, and other portable, battery-operated products in R&D and manufacturing environments. These battery-simulating power supplies are designed to recover very quickly from short-duration pulse load current changes as large as ...

Relationships between an assembler and a vendor in a supply chain are investigated in two-period models when the assembler wants to reduce response time by incentive systems. The assembler may offer myopic or farsighted incentive contracts to the vendor, under short-term or long-term relationships. Incentive schemes, effort levels, and expected payoffs under different perspectives and relations...

The standard static model of the e¤ect of welfare program participation on labor supply is estimated allowing the e¤ect of participation to be heterogeneous in the population and allowing the program participation decision to be endogenous and to exhibit incomplete takeup. A reduced form model is estimated with nonparametric methods to determine the distribution of the marginal treatment e¤ect ...
