This paper studies business hour decisions by retail chains and corner shops in a spatial retail market. We use a Salop-type model where retailers compete in prices and shopping hours. Assuming equally efficient firms, we find that the corner shop chooses no shorter business hours than a retail chain, but potentially longer ones. Additionally, we find that the firms have different stands toward...

This paper proposes a model featuring the heterogeneity of consumer preferences and analyzes the multiple equilibrium of retail formats by building a map of the relationships between consumer heterogeneity and retail formats. The key questions analyzed in this paper are how the retailer adjusts its combination of marketing elements through repositioning and how innovation in retail formats is i...

This paper studies the impact of Time-Of-Use (TOU) tariffs in a competitive electricity market place. Specifically, it focuses on the question of how should an autonomous broker agent optimize TOU tariffs in a competitive retail market, and what is the impact of such tariffs on the economy. We formalize the problem of TOU tariff optimization and propose an algorithm for approximating its soluti...

Consumers now purchase several offerings from direct sellers, including catalog and Internet marketers. These direct channels exist in parallel with the conventional retail stores. The availability of multiple channels has significant implications for the performance of consumer markets. The literature in marketing and economics has, however, been dominated by a focus on the conventional retail...

As retail choice states reach the end of their transitional, rate-cap periods, state regulators must decide what type of default supply service to provide to customers that have not switched to a competitive retail supplier. In a growing number of states, regulators have adopted real-time pricing (RTP) as the default service for large commercial and industrial (C&I) customers. Although this tre...

I investigate strategic interactions and market outcomes in the “agency model” and “wholesale model” of sales. Adopting the agency model initially raises prices, and can (but need not) raise the profits of rival retailers. Nonetheless, consumers prefer the agency model. I relate my results to events in the market for electronic books. I investigate the “agency model” and “wholesale model” of sa...

The power of agent-based modelling (ABM), when integrated with other AI-based and conventional approaches, can be greatly enhanced. The resulting hybrid systems offer a flexible modelling environment that exploits the benefits of the component methods. In particular, the ABM paradigm can be used to explore and understand systems that are governed by complex, non-linear relationships and self-or...
