How important are local country conditions to firms' operations performance, as revealed in their inventory levels? Under a “flat world” hypothesis, differences in firms' inventory levels are explained more by differences among industries and firms themselves, rather than differences among...

The discipline of operations management is rarely studied with an eye on public policies. Yet, it is glaring to even the casual observer that public infrastructure is very different in different countries. How does public infrastructure affect private sector inventory levels? I develop as a...

Sebastian de la Fuente is the sixth largest supermarket chain in the Basque region of Spain. It has a novel dataset of 108,605 observations on 3,745 SKUs, collected for almost 2 1/2 years. I find the bullwhip effect in the data: at least 80% of the SKUs have a bigger variance in supplies than...

How different are retailers' inventory levels around the world? Specifically, are retailers' inventories constant across countries, converging, or at least co-integrating? These might be viewed as various forms of global determinism. To see which of these forms hold, I use a novel dataset...

Demand patterns for products with seasonality and or short life-cycles do not follow a clear discernible pattern (to allow predictive time-series modeling of demand) for individual sales events or seasons due to such factors as considerable demand volatility, product promotions, and unforeseen...

In this paper we consider the classical newsvendor model with profit maximization. When demand is fully observed in each period and follows either the Rayleigh or the exponential distribution, appropriate estimators for the optimal order quantity and the maximum expected profit are established...

This paper considers the classical Newsvendor model, also known as the Newsboy problem, with the demand to be fully observed and to follow in successive inventory cycles one of the Exponential, Rayleigh, and Log-Normal distributions. For each distribution, appropriate estimators for the optimal...

Business Process Reengineering is a common topic in the field of Manufacturing and Production Engineering. There are few efforts in the area of Service industry using this framework. The present study is an effort to use the framework for improving efficiency in an Institute of Excellence in...

Any modern agricultural unit, regardless of profile, size, ownership and socio-economic space in which they operate, requires a management style based on flexibility, dynamism and foresight, which is inconceivable without a complex, operative and quality information, to underpin decision making....
