Bidirectional Causality for Word of Mouth and the Movie Box Office: An Empirical Investigation of Panel Data

Word-of-mouth (WOM) is informal communication between consumers about products and services. By using text mining techniques, WOM measured for volume and valence at the movie box office in Taiwan. A simultaneous regression of a panel Granger causality test for WOM and corresponding film performance was performed. The empirical results show that dynamic causality only runs from box office to WOM volume in the short run analysis, and the causality between WOM volume and box office is bidirectional in the long run analysis. Potential customers attend movies because of WOM in the short run, but in the long run, box office forms a signal and creates WOM. In WOM valence analysis, causality runs from positive critics to the box office in the short run, and it runs from negative critics to box office in the long run. WOM providers may need to develop different strategies for encouraging WOM behavior among their users. The implication for film managers and marketers is that a reliable way to affect box office is to stimulate positive critics in the short run and negative critics in the long run.     

作者关键词耦合分析方法及实证研究

本文介绍作者关键词耦合分析方法,并通过对科学计量学研究现状的分析对该方法进行了实证研究.作者关键词耦合网络与作者合著网络的QAP分析表明,两种网络之间具有相关关系,但前者与后者相比,更能揭示出作者间潜在的关系.通过社会网络分析中的核心/边缘分析表明,作者关键词耦合网络与作者同被引网络中的核心作者群有很大的不同,前者主要包括目前比较活跃的作者.上述两个网络的因子分析结果可视化发现,作者关键词耦合分析所揭示的研究主题更加清晰.同时,作者关键词耦合分析的结果表明,目前科学计量学的研究主题主要集中在科研评价研究,基础理论研究的内容比较少.

Robust Analysis of Movie Earnings

This article applies recently developed nonparametric kernel regression estimation methods to quantify the conditional distribution of motion picture earnings. The nonparametric, data-driven approach allows the full range of relations among variables to be captured, including nonlinearities that usually remain hidden in parametric models. The nonparametric approach does not assume a functional form, so specification error is not an issue. This study finds that the nonparametric regression model fits the data far better than the logarithmic regression model employed by most applied researchers; it also fits the data much better than a polynomial regression model. The nonparametric model yields substantially different estimates of the elasticity of box-office revenue with respect to production budgets and opening screens, and the model also has very good out-of-sample predictive ability, making it a potentially useful tool for studio management.     

The Great Immensity: A Theatrical Approach to Climate Change

In 2010, the Civilians—a New York based investigative theater company—received a three‐year grant from the National Science Foundation to develop The Great Immensity, a play addressing the complexity of climate change. The rigorous research that the Civilians puts into each production, the balance of scientific content and public engagement, the inclusion of scientists within the artistic development process, and the effort to engage a varied audience via a multi‐platform media approach, make the project a relevant case study for curators working with public science communication.

An introduction to the bibliography explains how the references were sought and identifies key themes that emerge from the research, particularly as they relate to media scholarship. Entries are listed in alphabetical order. Each citation is accompanied by an annotation of at least a few sentences that summarize the cited work's key points as they relate to Internet economics.     

Theatrical Feature Film Trade in the United States,Europe, and Japan Since the 1950s: An Empirical Study of the Home Market Effect

Abstract

This article reviews the test of a home market model of international trade in media products using a movie industry database covering 6 major countries (the United States, Japan, Germany, Italy, France, and the United Kingdom) over the 1950 to 2003 period. In support of the model, this study finds a consistently positive relation between domestic theater box-office market shares and various measures of domestic movie spending or domestic movie attendance, and negative relations between domestic movie spending and the market shares of imported American film products. Based on these results, declining domestic film production industries in Europe and Japan after about the 1970s, along with growing dominance of the world film market by the United States, is attributed to a relatively rapid growth of domestic consumer spending on movies in the United States.

The American Community Survey: An introduction to the basics

The Bureau of the Census initiated the American Community Survey (ACS) in 2005. It will revolutionize the use of census data by providing annual updates to statistics that in the past were collected only every 10 years. Statistics will be published for areas of 65,000 people or more every year. The Bureau of the Census will distribute data for areas of between 20,000 and 64,999 in "3-year period averages." The first 3 year average will appear in 2008 covering 2005–2007. Subsequent data will be issued annually for the following three year periods. (e.g., 2006–2008, 2007–2009) Statistics for areas smaller than 19,999 will be published in 5-year period averages, the first to be published in 2010 covering 2005–2009. Subsequent data to be issued annually will cover 2006–2010, 2007–20011, … This paper provides background information about ACS, similarities and differences between it and the decennial census, the interpretation of statistics based upon period averages, relationships among ACS and other Bureau of the Census Surveys, and the expected future of the survey.
