Aligning Incentives in Public Lending: The KfW COVID-19 Experience—Proposals for Improving Public Lending

Overview

This paper examines the structural design of public lending schemes with application to Germany's KfW emergency lending program during the COVID-19 pandemic. The research identifies incentive misalignments in two-tier lending arrangements involving national development banks, commercial banks, and firm borrowers. The analysis combines empirical observations from the KfW case with institutional analysis and theoretical modeling to develop contract design proposals that address moral hazard and adverse selection problems inherent in subsidized public lending.

Methods and approach

The study employs a mixed-methods approach integrating casual empirical evidence from the KfW COVID-19 lending scheme with institutional analysis of the two-tier lending mechanism. Normative theoretical modeling is used to construct optimal contract designs. The empirical component relies on observations from the German development bank's emergency program to identify specific contracting obstacles. Theoretical analysis develops signaling equilibrium models to characterize incentive structures and information revelation mechanisms in public lending relationships.

Key Findings

The analysis reveals critical incentive problems in subsidized public lending, including excessive participation by financially sound firms and inadequate screening of non-viable borrowers. The proposed contract structure creates a self-sorting mechanism where firms select contracts that maximize their subsidy while simultaneously revealing their credit ratings through contract choice. This partially revealing signaling equilibrium generates differentiated interest rates correlated with public funding requirements, thereby mitigating information asymmetries. Implementation of these contracts requires that participating banks retain a portion of borrower default risk, aligning their incentives with prudent lending practices and counteracting subsidized lending distortions.

Implications

The proposed contract design framework addresses fundamental challenges in public lending during crises by reducing adverse selection and moral hazard through incentive alignment. The mechanism allows public funds to direct support toward crisis-affected firms with genuine financing needs while discouraging applications from financially resilient firms and economically unviable enterprises. The retention of default risk by commercial banks serves as a disciplinary mechanism, ensuring that participation in public lending schemes remains consistent with maintaining lending standards.
