Technology Adoption and Network Externalities in Financial Systems: A Spatial-Network Approach
Tatsuru Kikuchi
This paper develops a unified framework for analyzing technology adoption in financial networks that incorporates spatial spillovers, network externalities, and their interaction.…
General Equilibrium Amplification and Crisis Vulnerability: Cross-Crisis Evidence from Global Banks
Tatsuru Kikuchi
This paper develops a continuous framework for analyzing financial contagion that incorporates both geographic proximity and interbank network linkages. The framework characterizes…
Dynamic Spatial Treatment Effects and Network Fragility: Theory and Evidence from the 2008 Financial Crisis
Tatsuru Kikuchi
The 2008 financial crisis exposed fundamental vulnerabilities in interconnected banking systems, yet existing frameworks fail to integrate spatial propagation with network contagio…
Dual-Channel Technology Diffusion: Spatial Decay and Network Contagion in Supply Chain Networks
Tatsuru Kikuchi
This paper develops a dual-channel framework for analyzing technology diffusion that integrates spatial decay mechanisms from continuous functional analysis with network contagion…
Network Contagion Dynamics in European Banking: A Navier-Stokes Framework for Systemic Risk Assessment
Tatsuru Kikuchi
This paper develops a continuous functional framework for analyzing contagion dynamics in financial networks, extending the Navier-Stokes-based approach to network-structured spati…
