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...

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...

Many service sector firms have utilised franchising to expand their business, and past literature has theorised and empirically investigated the antecedents of the strategy. This study examines the outcomes of franchising in the online food delivery sector from the customer’s perspective and...

This paper develops a dynamic econometric framework for the analysis of entry, exit, and competitive conduct in oligopolistic markets. This framework only requires panel data on the demand and producer counts of geographically dispersed markets over time. It is a dynamic extension of Bresnahan...

This paper establishes the existence and uniqueness of an intuitively-refined Markov-Perfect Equilibrium in a richly-specified dynamic duopoly model of entry and exit. We develop an algorithm that computes it very quickly, which makes the model useful for experiments that use many parameter...

I develop a dynamic oligopoly model to study the evolution of retail grocery: Grocery chains expand at the expense of independent local stores. Model estimation only requires panel data on store counts and market demand, yet it quantifies the determinants of chain stores' entry and the...
