Big Wins, Small Net Gains: Direct and Spillover Effects of First Industry Entries in Puerto Rico

Using staggered difference-in-differences on a decade of quarterly municipality data, this study finds a municipality's first sizable industry entries deliver large, persistent local employment and wage gains — but only small net gains once neighboring-area spillovers are netted out.

Short-Run Multi-Outcome Effects of Nightlife Regulation in San Juan

A multi-outcome synthetic-control evaluation of San Juan's late-night alcohol ordinance finds meaningful economic reallocation across restaurants, bars, and hospitality — but no clear change in public-disorder or violent-crime measures.

Disaster, Capital, and Neighborhood Change: Tract-Level Evidence on Post-María Gentrification in Puerto Rico

Tract-level machine-learning evidence that post-Hurricane María upgrading concentrated selectively in low-income neighborhoods with higher education and lower residential mobility — a path-dependent gentrification, with vulnerability measures to guide anti-displacement policy.

The Rule-Relocation Problem in Bio-Inspired AI

Argues "self-regulating" bio-inspired AI doesn't remove externally imposed objectives but relocates them — and proposes separating an explicit Safety Envelope from an internal Adaptive Space to keep normative authorship auditable and governable.

When GDP Is Not Enough: Puerto Rico, Statistical Boundaries, and the Limits of National Accounting in a Regional Economy

Argues Puerto Rico's macro-accounting problem is institutional, not technical — economically "external" yet statistically "internal" to U.S. accounts — so GDP modernization alone can't resolve ambiguity about resident income and external dependence.

When GDP Is Not Enough: Q&A on Puerto Rico's Macroeconomic Accounts, Statistical Boundaries, and Accounting Closure

A diagnostic companion that tests whether Puerto Rico's published aggregates (GDP, GNP, BOP) form a closed, coherent system — using official PRPB and BEA methodology quotations to pinpoint measurement gaps and their policy consequences.

Regulatory Forbearance and Depositor Stickiness in Puerto Rico's Credit Union System: A Chronicle of Act 220-2015 and the Insolvency-Illiquidity Risk

Chronicles how Puerto Rico's cooperative credit unions weathered the 2013–18 collapse in their government-debt holdings — a legislative accounting override (Act 220-2015) that deferred loss recognition, paired with common-bond depositor loyalty that prevented the deposit flight which would have forced bond liquidation at distressed prices.

About Jorge A. Arroyo

xP&A & Data Consultant · Analytics Engineer & Developer

With over 10 years immersed in finance and analytics, I saw a critical need among local businesses: the need to bridge the gap between complex financial planning and the wealth of operational data often locked away in separate systems. SENS ADVISOR was born from an idea to address this: to empower organizations by integrating these domains through expert Extended Planning & Analysis (xP&A) and full-stack enterprise application development that transforms how businesses manage their financial and operational workflows.

I mainly focus on designing and deploying cloud-based xP&A and Business Intelligence systems using Microsoft Azure, Power BI, and advanced Excel techniques, while also architecting sophisticated full-stack business applications with enterprise-grade security, role-based access control, and real-time data synchronization.

Since 2022, I've pursued AI and LLM research as a purposeful hobby to stay current with rapidly evolving technology and to rigorously test what works versus what doesn't in real business implementations. This is how I maintain a ground-truth understanding of AI's current capabilities and limitations which allows me to provide clients with realistic assessments of AI opportunities, honest guidance on implementation risks, and evidence-based recommendations for efficiency gains.
