Short-Horizon Claim Concentration and Operating Efficiency
Overview
This project evaluates whether the share of current liabilities in total liabilities predicts subsequent operating efficiency. The final decision is to retain the fixed-effects evidence and reject the invalid GMM specifications.
Research Question
Does short-horizon claim concentration predict future asset turnover and related operating outcomes within Vietnamese listed firms?
Economic or Technical Motivation
A larger share of near-term claims may impose settlement pressure that disciplines asset use, but it may also reflect financial fragility or reverse selection. The design tests prediction within firms without assigning a causal mechanism.
Data
The source panel covers 2010–2024. The confirmatory sample uses nonfinancial firms during 2016–2024; the main model contains 9,144 observations and 1,405 firms. Short-horizon claim concentration is current liabilities divided by total liabilities, not a short-term debt ratio.
Methodology
The pipeline uses dynamic firm fixed effects with clustered standard errors, prespecified alternative outcomes and samples, reverse-direction models, COVID sensitivity, multiple-testing correction, and System GMM diagnostics.
Main Findings
Lagged claim concentration is positively associated with future asset turnover: 0.1011 with SE 0.0488 and p=0.0385. A p25-to-p75 shift corresponds to 0.0281 asset-turnover units, or 0.023 outcome standard deviations. Secondary ROA and CFO/assets estimates are positive before family-wise correction.
Robustness, Validation, or Model Assessment
The main sign is retained in all comparable robustness models, while 56% have p-values below 0.05. Raw-outcome, rank, and COVID-excluded variants are less precise. All System GMM variants fail required diagnostics; those estimates are rejected rather than used as confirmation.
Tools and Technologies
Stata 17, reghdfe, firm fixed effects, clustered inference, panel diagnostics, Holm and Benjamini–Hochberg adjustments, and System GMM auditing are directly demonstrated.
Limitations
The effect is small, statistical significance is not uniform across transformations, and reverse selection is not ruled out. Dynamic fixed effects may be biased in a short panel, while the attempted GMM remedy fails its diagnostics.
