Public borrowing in Nigeria consistently fails to translate into measurable development outcomes

This study argues that Nigeria's persistent failure to convert its massive public debt into measurable development outcomes stems not from borrowing itself, but from deep-seated governance failures that divert funds toward consumption and debt servicing rather than productive investment, necessitating comprehensive accountability reforms to ensure borrowed capital yields tangible public benefits.

Financial intermediation for climate abatement: Bank monitoring and the design of multilateral public-private partnerships

This paper demonstrates that while bilateral contracts fail to simultaneously induce effort, attract investors, and implement green projects, a five-partner architecture featuring a monitoring bank with fees contingent on verified abatement can resolve this impossibility, a critical design element currently missing from existing multilateral climate finance vehicles.

The Impact of Post-2008 New-Generation Fiscal Rules on the Current Account Balance: A Generalized Synthetic Control Approach

Using a Generalized Synthetic Control Method on a panel of 111 countries from 2000 to 2019, this study demonstrates that post-2008 adoption of new-generation Balanced Budget and Debt fiscal rules significantly improves both the primary budget and current account balances, thereby confirming the Twin Deficits hypothesis and rejecting Ricardian equivalence.

Crossing into AI: When Incumbents Build, Partner, Acquire, Absorb, or Wait A History-Friendly Agent-Based Model of the Generative-AI Market Transition

This paper employs a history-friendly agent-based model to demonstrate that incumbent firms' strategic choices in the generative AI market—ranging from building and acquiring to the novel "absorption" route—are primarily determined by the contractibility of tacit capabilities and the intensity of regulatory scrutiny, with no single strategy dominating across all conditions.

Multi-objective Portfolio Optimization Based on the Fama–French Three-Factor Model and the Black–Litterman Framework

This study proposes a robust multi-objective portfolio optimization model that integrates the Fama–French three-factor model with the Black–Litterman framework to generate posterior expected returns while simultaneously minimizing downside risk and maximizing diversification under practical constraints, demonstrating superior performance over benchmark strategies in both in-sample and out-of-sample tests.

Network-Adaptive Climate-Finance Stress Testing: Monte Carlo Evidence on Transition-Linked Credit, Capital Buffers, and Systemic Resilience

This study employs a network-adaptive Monte Carlo framework to demonstrate that an integrated climate governance strategy, which jointly adjusts credit allocation and capital buffers based on both carbon intensity and network centrality, significantly outperforms static or carbon-only approaches in mitigating systemic financial losses and bank failures under severe climate transition scenarios.
