Empirical Generalizations

The importance of pricing decisions for firms has fueled an extensive stream of research on price elasticities. In an influential meta-analytical study, Tellis (1988) summarized price elasticity research findings until 1986. However, empirical generalizations on price elasticity require modifications because of (1) changes in market characteristics (i.e., characteristics of brands, product categories, and economic conditions) and (2) changes in the research methodology used to assess price elasticities. Therefore, the authors present a meta-analysis of price elasticity with new empirical generalizations on its determinants. Across a set of 1851 price elasticities based on 81 studies, the average price elasticity is −2.62. A salient finding is that over the past four decades, sales elasticities have significantly increased in magnitude, whereas share and choice elasticities have remained fairly constant. The authors find that accommodating price endogeneity has a strong (magnitude-increasing) impact on price elasticities. A striking null result is that accounting for heterogeneity does not affect elasticities significantly. The authors also present an analysis that explains the difference between their findings and Tellis's findings, and they indicate which new price elasticity studies are most desirable.

Price Responsiveness

Many studies have examined the demand for gambling, providing roughly 200 estimates of the price elasticity associated with horse racing, casino gaming, and the lottery.  Treating these price elasticities as observations of the dependent variable in a meta-regression model, several features of the literature are found to influence the price responsiveness of gambling.  For instance, the price elasticity of casino gambling is lowest in absolute value, while the price elasticities of horse racing and the lottery are of similar value.  Also, not only are there regional differences in the price elasticity of gambling, but other model features, such as the functional form of gambling demand, are found to influence the price elasticities.

Intragroup Competition

This study examines whether intragroup cooperation outperforms intragroup competition. Intragroup cooperation is a work setting when individuals in a group perceive that their goal attainments are positively related; while intragroup competition is a work setting when individuals in a group perceive that their goal attainments are negatively related. Performance is defined as group productivity level, speed of solving problems, and quality of the group outcomes.Meta-analytical method is used to test the hypothesis. The method combines and compares eight studies from various research disciplines i.e., education, psychology, organization, and business and accounting. The studies being analyzed also vary in terms of the research and experimental setting such as manufacturing operations and problem solving games.Meta-analytical study is relatively rare in Indonesia, so that this study is important to introduce and to show the importance and the benefit of the analysis for concluding a large number and different research in a similar domain of research question.  In a simple term, a meta-analysis is a quantitative literature review. However, the analysis has a more powerful procedure (than the conventional literature review) to indicate more clearly, and in quantitative terms, the consistency, the differences and similarities of previous studies.The author found that intragroup cooperation outperforms intragroup competition is held across different experimental subject educational backgrounds such as education, psychology, and business and accounting. However, the extent of the difference in performance is higher in the subjects with psychology background than that of the subjects with business and accounting background. The reason is that business and accounting subjects are more exposed to competitive environments than those whose backgrounds are psychology and sociology.

Tax deductibility has been recognized as a motive for charitable donations. This article considers charitable donations as purchases that consumers make, and it examines the effects of changes in the tax deductibility (i.e., the price of donating) on charitable donations. The meta-analysis includes approximately four decades of estimates of the price elasticity of charitable giving. The authors discuss implications for policy makers and the marketers of charities.

The author describes a meta-analysis of econometric studies that estimated the elasticity of selective sales or market share to price. The literature review yielded 367 suitable price elasticities from about 220 different brands/markets. The results indicate that the price elasticity is significantly negative and, in absolute value, eight times larger than the advertising elasticity obtained from a prior meta-analysis. The omission of distribution or quality, the use of only cross-sectional data, and temporal aggregation lead to severe biases in the estimates of price elasticity. The elasticity also differs significantly over the brand life cycle, product categories, estimation methods, and countries.

Summary: Our meta-analysis focused on the relationship between homocysteine (Hcy) level and the incidence of aneurysms and looked at the relationship between smoking, hypertension and aneurysms. A systematic literature search of Pubmed, Web of Science, and Embase databases (up to March 31, 2020) resulted in the identification of 19 studies, including 2,629 aneurysm patients and 6,497 healthy participants. Combined analysis of the included studies showed that number of smoking, hypertension and hyperhomocysteinemia (HHcy) in aneurysm patients was higher than that in the control groups, and the total plasma Hcy level in aneurysm patients was also higher. These findings suggest that smoking, hypertension and HHcy may be risk factors for the development and progression of aneurysms. Although the heterogeneity of meta-analysis was significant, it was found that the heterogeneity might come from the difference between race and disease species through subgroup analysis. Large-scale randomized controlled studies of single species and single disease species are needed in the future to supplement the accuracy of the results.

Eye Movements During Reading

Abstract. We report the results of a meta-analysis of 22 experiments comparing the eye movement data obtained from young ( Mage = 21 years) and old ( Mage = 73 years) readers. The data included six eye movement measures (mean gaze duration, mean fixation duration, total sentence reading time, mean number of fixations, mean number of regressions, and mean length of progressive saccade eye movements). Estimates were obtained of the typified mean difference, d, between the age groups in all six measures. The results showed positive combined effect size estimates in favor of the young adult group (between 0.54 and 3.66 in all measures), although the difference for the mean number of fixations was not significant. Young adults make in a systematic way, shorter gazes, fewer regressions, and shorter saccadic movements during reading than older adults, and they also read faster. The meta-analysis results confirm statistically the most common patterns observed in previous research; therefore, eye movements seem to be a useful tool to measure behavioral changes due to the aging process. Moreover, these results do not allow us to discard either of the two main hypotheses assessed for explaining the observed aging effects, namely neural degenerative problems and the adoption of compensatory strategies.

Abstract The study was set to examine the differences between religion and religiosity and to explore how communities can be protected against religious violence. The study also intended to investigate the motives and the effect that religious violence has had throughout history. The study employed the qualitative research method whereby the researcher carried out a meta-analysis synthesis of different research findings to make conclusions and implications that could answer the study questions. Using the literature review they conducted, the researchers carried out data collection. As such, the researcher employed the bottom-up approach to identify the problem and the questions along with the investigation framework of what they decided to explore. The findings of the study revealed that religious backgrounds should be the cornerstone to realize the diff erence between religion and religiosity. Religion is of divine origin whereas religiosity is specifically a humanistic approach and a behavioral model. The religious violence phenomenon is formed by interlocking factors such as the interpretation of religious texts which clearly adopt thoughts and heritage full of violence camouflaged by religion. It is recommended that governments use a strong strategy employing the educational system, summits and dialogs to successfully overcome religious violence. The summits on religion should result in starting a dialog that ensures acceptance of the different religions.

Abstract Objective The COVID-19 outbreak started in Italy on February 20th, 2020, and has resulted in many deaths and intensive care unit (ICU) admissions. This study aimed to illustrate the epidemic COVID-19 growth pattern in Italy by considering the regional differences in disease diffusion during the first three months of the epidemic. Study design and methods Official COVID-19 data were obtained from the Italian Civil Protection Department of the Council of Ministers Presidency. The mortality and ICU admission rates per 100 000 inhabitants were calculated at the regional level and summarized via a Bayesian multilevel meta-analysis. Data were retrieved until April 21st, 2020. Results The highest cumulative mortality rates per 100 000 inhabitants were observed in northern Italy, particularly in Lombardia (85.3, 95% credibility intervals [CI] 75.7–94.7). The difference in the mortality rates between northern and southern Italy increased over time, reaching a difference of 67.72 (95% CI = 66–67) cases on April 2nd. Conclusions Northern Italy showed higher and increasing mortality rates during the first three months of the epidemic. The uncontrolled virus circulation preceding the infection spreading in southern Italy had a considerable impact on system burnout. This experience demonstrates that preparedness against the pandemic is of crucial importance to contain its disruptive effects.
