Is Meta-Analysis a Noah's Ark for Non-Market Valuation?

This paper describes meta-analytical methods as they have been appliedto non-market valuation research. These studies have been used to reviewand synthesize literature and, more recently, in benefit transfer. Thissecond use imposes a higher standard on the consistency in economicconcepts being summarized and in the resources included in ameta-analysis. To meet this need, the paper proposes and illustrates astructural framework using a generalized method of moments estimator toestimate the parameters of a preference function with the benefitsestimates usually encountered in meta-analytic summaries.     

REPORTING GUIDELINES FOR META-ANALYSIS IN ECONOMICS

Meta-analysis has become the conventional approach to synthesizing the results of empirical economics research. To further improve the transparency and replicability of the reported results and to raise the quality of meta-analyses, the Meta-Analysis of Economics Research Network has updated the reporting guidelines that were published by this Journal in 2013. Future meta-analyses in economics will be expected to follow these updated guidelines or give valid reasons why a meta-analysis should deviate from them.     

Revisiting the effect of regional integration on African trade: evidence from meta-analysis and gravity model

Two main shortcomings flaw the estimation of gravity model in previous studies that examined the trade-creating effects of African Regional Trade Agreements (RTAs). First, these studies fail to account for the multilateral resistance term. This omission makes the estimates from standard gravity model bias and inconsistent. Second, there is a significant proportion of zero trade flows, however, these studies also fail to account for them properly. They use either the Tobit model or replace zero flows with arbitrary small values. Apart from these problems, they also exhibit considerable heterogeneity in the RTA effects on trade. In this paper, a meta-analysis of previous empirical studies is conducted to derive a combined effect size and also to explain the heterogeneity. In addition, I use the gravity model to compare the trade-creating effect of the main African RTAs. Using the gravity model, I compare the estimation methods of previous studies to the Poisson pseudo-maximum-likelihood estimator that tackles the zero flows. From the meta-analysis, I find a general positive effect of African RTAs of about 27%–32%. A comparative assessment of the RTAs using gravity model shows a striking heterogeneity.     

Festival attributes and perceptions: A meta-analysis of relationships with satisfaction and loyalty

Festivals provide economic, social and cultural benefits to the communities in which they occur, and contribute to event tourism and destination marketing. This research reports a meta-analysis of the festival literature to evaluate the factors that contribute to festival satisfaction and loyalty. Attributes were classified into six categories: activities, authenticity/uniqueness, concessions, environment, escape and socialization. The analysis revealed that festival activities (program, entertainment, thematic activities) and environment (atmosphere, convenience, facilities) are the most important determinants of satisfaction and loyalty. Two perceptions were evaluated: cost/value and service quality. The analysis revealed that cost/value is important for both satisfaction and loyalty, whereas service quality is relatively unimportant. Satisfaction with the festival is strongly related to loyalty. The findings suggest that festival planners should focus on providing an enjoyable program in a comfortable environment at a reasonable price. This strategy will cultivate repeat attendance and stimulate future visits to the festival destination.

Constraints to Park Visitation: A Meta-Analysis of North American Studies

The constraints that curb visitation to parks have received considerable research attention and remain an important issue. Constraints to outdoor leisure in parks include structural barriers, such as cost of entry, interpersonal barriers, for example, lack of a partner to visit with, or intrapersonal barriers, including lack of interest. Using a meta-analysis approach, this article integrates the findings of 22 North American studies with 541 estimates, conducted over a 30-year period, to determine the key constraints to park visitation based on various socio-demographic factors. The findings highlight the varying roles that constraints play in limiting the visitation of people according to race, age, gender, education and income. Gaps in the literature are identified, with implications for encouraging visitation for more constrained groups discussed. An agenda for future research is presented.     

Ethnic Identity in Advertising: A Review and Meta-Analysis

The corpus of research on ethnic identity in advertising indicates that (1) ethnic identity influences commonly examined attitudinal and purchase-intention outcomes, and (2) attitudes toward both the actor(s)/model(s) and the ad moderate attitudes toward brands depicted in ethnically resonant ads. Individual studies often differ by measurement type (i.e., single-item measure versus multi-item scale), study design (i.e., experiment versus survey), and diversity of respondent sample. Seemingly, ethnic-identity effects are greater for studies that relied on single-item measures, experimental designs, and more diverse samples. Implications and future research directions are suggested.     

The Wage Elasticity of Labour Supply: A Synthesis of Empirical Estimates

Summary This paper performs a meta-analysis of empirical estimates of uncompensated labour supply elasticities. For the Netherlands, we find that an elasticity of 0.5 for women and 0.1 for men is a good reflection of what the literature reveals. The elasticity for men hardly differs between countries, but for women some cross-country variation is found. The increasing participation rate of women may lead to a somewhat lower elasticity in the future. Both the specification of the hours function and the estimation method are found to affect elasticity estimates.
