• Structural Equation Modeling (SEM) testing and validation shifted toward explicit latent-variable measurement and confirmatory testing, integrating fit assessment, measurement error, and latent structure checks across psychometrics and economics [1], [4], [17], [14]

• Structural-change and dynamic stability research investigates how models detect shifts, leverage time variation, and assess test power under nonstationarity, including locally almost unidentified (LAU) parameters concerns and CUSUM-based approaches [8], [18], [6], [12]

• Foundations, history, and methodological debates in econometrics explore the epistemology and development of econometric methods, from instrumentalism vs realism to formal identification and pedagogy of econometrics as a science [2], [3], [7], [5], [13], [10]

• Dynamic modeling and representational aspects emphasize long-run specification, transformed regression models, and dynamical feedback in econometrics, highlighting specification challenges in dynamic systems [11], [9]
