Guidelines for Meta‐Analytic Structural Equation Modeling: Steps, Resources, and Illustrations
Psychology &Marketing, EarlyView.ABSTRACT The goal of science is to build incremental, structured, and reliable knowledge over time. Yet, many strands of marketing and related disciplines exhibit symptoms of cumulative stagnation, including lack of replicability and weak theoretical integration. Existing remedies such as replication studies, multistudy investigations, and open science
