Estimating Discrete Joint Probability Distributions for Demographic Characteristics at the Store Level Given Store Level Marginal Distributions and a City-Wide Joint Distribution

This paper provides a solution to the problem of estimating a joint distribution using the associated marginal distributions and a related joint distribution. The particular application we have in mind is estimating joint distributions of demographic characteristics corresponding to market areas for individual retail stores. Marginal distributions are generally available at the census tract level, but joint distributions are only available for Metropolitan Statistical Areas which are generally much larger than the market for a single retail store. Joint distributions over demographics are an important input into mixed logit demand models for aggregate data. Market shares that vary systematically with demographics are essential for relieving the restrictions imposed by the Independence from Irrelevant Alternative property of the logit model.We approach this problem by formulating a parametric function that incorporates both the city-wide joint distributional information and marginal information specific to the retail stores market area. To estimate the function, we form moment conditions equating the moments of the parametric function to observed data, and we input these into a GMM objective. In one of our illustrations we use four marginal demographic distributions from each of eight stores in Dominicks Finer Foods data archive to estimate a four dimensional joint distribution for each store. Our results show that our GMM approach produces estimated joint distributions that differ substantially from the product of marginal distributions and emit marginals that closely match the observed marginal distributions. Mixed logit demand estimates are also presented which show the estimates to be sensitive to the formulation of the demographics distribution.The views expressed are not purported to reflect those of the United States Department of Justice     

Television Advertising: In Need of Reinvention?

As the media technologies carrying advertising messages advance in sophistication, commercial communication inexorably becomes more fragmented, more targeted and individual in focus, and more consumer-driven. Advertising as an industry continues to grow, but is still based on its original mass-communication models. The industry must now consider reinventing itself.     

Does Congruence with an Entrepreneur Social Identity Encourage Positive Emotion Under Environmental Dynamism?

Entrepreneurial identities and emotions can have profound effects on entrepreneurs. We examine how positive emotion (PE) among entrepreneurs may be influenced by the congruence they experience between their self‐concept and the entrepreneur social identity. Given that uncertainty in the business environment can exert powerful effects throughout the entrepreneurial process, we further test the moderating impact of environmental dynamism on the relationship between identity congruence and PE. Results from a study of 175 entrepreneurs indicate that entrepreneurs experiencing greater congruence have higher levels of PE, and that this relationship is stronger in more dynamic environments.     

Technological Scanning by Small Canadian Manufacturers

Given that in many industries new production and information technologies have fundamentally changed the way in which firms must operate and compete, the technological aspect of environmental scanning has become a critical success factor for many small and medium-sized manufacturing enterprises. As little is presently known about how technological scanning manifests itself in these organizations and about what determines the nature and level of this activity, a survey study of 324 Canadian firms was done. Testing a research model resulted in identifying four interrelated dimensions of scanning activity, namely scanning objectives, type of information, information sources, and management practices. Key determinants of this activity were also identified, including the firms' strategy, environmental uncertainty, production technology, level of R&D, information networks, and the owner-manager's education level.     

From reviving tradition to fostering innovation and changing marketing: the evolution of micro-brewing in the UK and US, 1980–2012

Abstract

The purpose of this article is to explore and examine the impressive growth of small and micro-breweries registered in the UK and US from the early 1980s. While the majority of British and American breweries continue to operate in spatially restricted areas and niche markets, a few businesses expanded significantly in terms of production and turnover, gradually acquiring larger shares of the market and competing with multinational producers at home as well as abroad. The cases of BrewDog and Sierra Nevada, used as case study examples in this article, provide an original account on how once-upon-a-time micro-breweries grew into well established companies by pursuing aggressive strategies in terms of marketing and innovation respectively.     

State Income Taxes and Interstate Migration

This paper examines the comprehensive IRS data set of state-state migration flows for evidence that differences in state income tax rates are associated with migration patterns. Using annual data on moves between every pair of states, pooled time-series cross-section regressions indicate that in the 1992–2010 period states with higher top marginal income tax rates experienced relatively greater outmigration of taxpayers and gross income. To illustrate the magnitude of the tax effect, we estimate that by 2010 cumulative losses since the enactment of New Jersey’s 2004 “millionaires’ tax” were as much as 42,000 taxpayers and $6.9 billion in annual adjusted gross income. These results suggest that sustained, relatively high income tax rates could gradually erode a state’s population and revenue base.
