Data Analysis & Cross-National Validity (jibs-data-analysis)

When to trigger

• Cross-country or multilevel data are collected and it is time to estimate and report
• You are unsure your estimator matches nesting (individuals in firms in countries) or a process design
• Reviewers will probe measurement equivalence, CMV, or (dynamic) endogeneity
• A reviewer cites a JIBS "From the Editors" methods editorial against your analysis

Establish cross-national measurement equivalence first

At JIBS, because constructs travel across countries and cultures, measurement equivalence is a first-order review concern, not an afterthought. Before testing hypotheses:

• Reliability & CFA. Report reliability (alpha/composite reliability) and a confirmatory factor analysis with fit (CFI, TLI, RMSEA, SRMR).
• Measurement invariance. Run multi-group CFA and report configural → metric → scalar invariance across countries; if scalar fails, report partial invariance or the alignment method and discuss what cross-country comparisons remain defensible.
• Construct & discriminant validity. AVE per construct; AVE > inter-construct squared correlations (or HTMT). Report the correlation matrix with reliabilities on the diagonal.
• Aggregation (multilevel). Justify any aggregation to the country/firm level with ICC(1), ICC(2), and r_wg(j).
• Qualitative designs. Where the design is case-based, "validity" becomes trustworthiness — a transparent data structure, an audit trail, and representative cross-case quotations.

Match the estimator to the cross-country/multilevel design

Data structure / claim	Estimator
Individuals/firms nested in countries	Multilevel / HLM (random intercepts/slopes); country-level Xs
Latent constructs across groups, mediation	Multi-group / multilevel SEM
Internationalization as a path-dependent process	Dynamic panel (system/diff GMM), firm FE, lagged DVs
Cross-border entry-mode / location choice	Logit/probit/multinomial; conditional/mixed logit
Cross-country count/limited DV	Poisson/negative binomial; Tobit/Heckman as fits

Cluster standard errors to the country (or country-year) structure.

Common-method variance (CMV) — an active JIBS gatekeeper

JIBS routinely asks survey/same-respondent papers that appear to suffer from CMV to run validity checks and resubmit. A Harman single-factor test alone is not sufficient. Report the designed separations first (from jibs-methods), then statistical evidence: a marker-variable approach, an unmeasured latent method factor (CFA), or showing interaction/cross-level effects survive (these are hard to inflate by CMV). Cite the JIBS "From the Editors" CMV editorial.

Endogeneity and "dynamic endogeneity"

For internationalization-as-process designs, address dynamic endogeneity explicitly: past strategy, performance, and unobserved firm heterogeneity co-evolve. Execute the identification planned at design (instruments and first-stage strength, dynamic-panel GMM with instrument-count and Hansen/AR(2) diagnostics, DiD/natural experiment, or selection models) and discuss the assumptions. Reviewers anchor this to the JIBS endogeneity/dynamic-endogeneity editorials.

Reporting & robustness

• Mediation: bias-corrected bootstrap CIs (e.g., 5,000 resamples); conditional indirect effects for moderated mediation.
• Moderation/cross-level interactions: report the coefficient and plot simple slopes; report incremental variance.
• Effect sizes: report magnitudes, not only p-values (a JIBS p-value editorial cautions against p-value worship).
• Robustness: alternative country samples (drop influential countries), alternative distance measures, alternative specifications; sensitivity to endogeneity assumptions.

Anti-patterns

• Pooling countries without testing measurement invariance.
• Single-factor (Harman) test as the sole CMV defense.
• OLS on country-nested data, ignoring non-independence.
• Internationalization-process regressions with no dynamic-endogeneity treatment.
• Reporting p-values with no effect sizes or practical magnitude.
• Treating cultural/institutional distance as a black-box covariate.
