This article presents the relationship between a firm’s advertisement spending and sales in a duopoly when information about the competitors’ advertisement spending is unavailable. The competitive interaction between the firms has been modeled as imperfect information Cournot and Stackelberg...

The paper focuses on a methodology for creating adaptive high fidelity market response models that enable the measurement and tracking of the effectiveness of a firm’s marketing investments over long time horizons. The methodology uses a log-linear model with latent classes and is robust to...

Firms have lately been increasing their investments in digital video advertising at the expense of television advertising. We examine the efficacy of such investments with a media efficiency and saturation analysis on longitudinal datasets from a national restaurant chain, and a national food...

There is growing interest in developing the abilities to simulate realistic social networks and analyze data generated from existing online social networks such as Facebook and Twitter. Amongst other things, researchers and practitioners need these abilities to study how opinions and information...

This paper presents a restricted maximum likelihood-based algorithm to estimate who influences whose opinions and to what degree when agents share their opinions over large online social networks such as Twitter. The proposed algorithm uses multi-core processing and distributed computing to...

This paper presents a stochastic opinion dynamics model where (a) the opinion of each agent in a network is modeled as a probability distribution as against a point object, (b) consensus is defined as the stability region of the ensuing set of stochastic difference equations, and (c) compromise...

Weather, especially temperature, plays an important role in determining the supply and demand for a vast variety of goods and services. Though the economic impact of extreme weather is often measured and reported, the impact of systematic changes in weather, such as long-term temperature trends...
