Advertising Creativity Matters

Abstract: Could "wasteful" advertising creativity that does not add to the functionality of the advertisement (i.e., it neither enhances recall and liking of the advertising, nor increases comprehension and ...

Trade Liberalization and Productivity Growth

Abstract: This paper presents a trade model with firm-level productivity differences and R&D-driven growth. Trade liberalization causes the least productive firms to exit but also slows the development of new products. The overall effect on productivity growth depends on the size of intertemporal knowledge spillovers in R&D. When these spillovers are relatively weak, then trade liberalization promotes productivity growth in the short run and makes consumers better off in the long run. However, when these spillovers are relatively strong, then trade liberalization retards productivity growth in the short run and makes consumers worse off in the long run.

Effects of information technology failures on the market value of firms

Abstract: IT failures abound but little is known about the financial impact that these failures have on a firm's market value. Using the resource-based view of the firm and event study methodology, this study analyzes how firms are penalized by the market when they experience unforeseen operating or implementation-related IT failures. Our sample consists of 213 newspaper reports of IT failures by publicly traded firms, which occurred during a 10-year period. The findings show that IT failures result in a 2% average cumulative abnormal drop in stock prices over a 2-day event window. The results also reveal that the market responds more negatively to implementation failures affecting new systems than to operating failures involving current systems. Further, the study demonstrates that more severe IT failures result in a greater decline in firm value and that firms with a history of IT failures suffer a greater negative impact. The implications of these findings for research and practice are discussed.

Genotype–covariate interaction effects and the heritability of adult body mass index

Abstract: Obesity is a worldwide epidemic, with major health and economic costs. Here we estimate heritability for body mass index (BMI) in 172,000 sibling pairs and 150,832 unrelated individuals and explore the contribution of genotype-covariate interaction effects at common SNP loci. We find evidence for genotype-age interaction (likelihood ratio test (LRT) = 73.58, degrees of freedom (df) = 1, P = 4.83 × 10-18), which contributed 8.1% (1.4% s.e.) to BMI variation. Across eight self-reported lifestyle factors, including diet and exercise, we find genotype-environment interaction only for smoking behavior (LRT = 19.70, P = 5.03 × 10-5 and LRT = 30.80, P = 1.42 × 10-8), which contributed 4.0% (0.8% s.e.) to BMI variation. Bayesian association analysis suggests that BMI is highly polygenic, with 75% of the SNP heritability attributable to loci that each explain <0.01% of the phenotypic variance. Our findings imply that substantially larger sample sizes across ages and lifestyles are required to understand the full genetic architecture of BMI.

When is Advertising Advertising? Comparing Responses to Non-Traditional and Traditional Advertising Media

Abstract: This paper investigates how consumers identify advertising. Research on new advertising formats such as advertorials etc. shows that they may be more effective than traditional advertising formats. While building on the underlying assumption that the new advertising formats blur the boundaries between advertising and its surrounding content, this has never been tested directly. We draw upon representation and categorization theory to hypothesize that a new advertising format, such as placing an ad message in a non-traditional advertising medium (which has never previously featured advertising), makes it more difficult to identify the message as advertising. As a result, consumers should activate their advertising schemas to a lesser extent and evaluate the message more favorably. An experiment, in which the ad message was placed in either a traditional or non-traditional medium, confirmed the hypotheses.
