Supplier reliability is a key determinant of a manufacturer’s competitiveness. It reflects a supplier’s capability of order fulfillment, which can be measured by the percentage of order quantity delivered in a given time window. A perfectly reliable supplier delivers an amount equal to the...

The fact that wineries tend to cluster can be partially explained by the terroir of those areas. However, a gap in our understanding of the spatial relationships among wineries remains. In this article, winery-level data from California and Washington State with GIS coordinates are utilized to...

From nitrogen and phosphorus, chemical oxygen demand, phytoplankton, and eutrophication, this article analyzes the current situation of water quality in the Dongting Lake area, and discusses the factors influencing the water quality of Dongting Lake. Based on the actual production, geographic...

We characterize the equilibrium behavior in a broad class of competition models in which the competing firms' market shares are given by an attraction model, and the aggregate sales in the industry depend on the aggregate attraction value according to a general function. Each firm's revenues and...

This paper develops an econometric model of industry dynamics for concentrated markets that can be estimated very quickly from market-level panel data on the number of producers and consumers using a nested fixed-point algorithm. We show that the model has an essentially unique symmetric...

This paper develops a tractable model for the computational and empirical analysis of infinite-horizon oligopoly dynamics. It features aggregate demand uncertainty, sunk entry costs, stochastic idiosyncratic technological progress, and irreversible exit. We develop an algorithm for computing a...

The fact that wineries tend to cluster in certain sub-regions can be partially explained by the terroir of those areas. However, a gap in our understanding of the spatial relationships among wineries remains. In this article, winery-level data with geographic information system (GIS) coordinates...

In this article, we evaluate how sensory qualities of wine, such as astringency, bitterness, aroma, and flavor, affect consumers' willingness to pay for wine. In order to accomplish this objective, we utilize data collected from untrained consumers, a trained panel, and laboratory measurements...
