Estimation of factor structured covariance mixed logit models [PDF]
Journal of Choice Modelling, 2018 Abstract Mixed logit models with normally distributed random coefficients are typically estimated under the extreme assumptions that either the random coefficients are completely independent or fully correlated. A factor structured covariance offers a range of alternatives between these two assumptions.

Growth of Omnichannel Grocery Retailing and Food Prices
Agribusiness, EarlyView.ABSTRACT This paper examines the effects of the growth of omnichannel grocery retailing on food prices. We first develop a conceptual model of consumer choice and retailer pricing that allows us to evaluate changes in equilibrium prices, quantities, and profits with online channel growth and alternative pricing strategies.

Bayesian Flexible Modelling of Mixed Logit Models
, 2010 The widespread use of the Mixed Multinomial Logit model, in the context of discrete choice data, has made the issue of choosing a mixing distribution very important. The choice of a specific distribution may seriously bias results if that distribution is not suitable for the data. We propose a flexible hierarchical Bayesian approach in which the mixing

Measurement of Cannibalism Effects in buying experiments using Mixed Logit Models - The Example of a new Brand of the “Fruits of Lake Constance” Association - [PDF]
One fundamental assumption of discrete choice regression is the assumption of independence of irrelevant alternatives (IIA). According to the IIA assumption no correlation is allowed between brands in buying experiments.

Agribusiness, EarlyView.ABSTRACT Despite the broad focus on necessity‐ and opportunity‐driven entrepreneurship in research and policy, the entrepreneurial dichotomy within the agribusiness context has not been adequately addressed. This study contributes to closing this knowledge gap by examining youth's perceptions of agribusiness through the lens of the push‐pull motivation

U.S. Consumer Preferences for Cage‐Free Eggs and Hen Housing Policies
Agribusiness, EarlyView.ABSTRACT Farm animal welfare (FAW) continues to be a divisive issue in the egg industry. In the United States, 10 states and most major retailers have implemented policies or voluntary pledges to transition to 100% cage‐free egg sales. We use best‐worst scaling and discrete choice experiments to evaluate U.S.
