This guide provides essential knowledge for selecting and defending data sources for advanced research in international economics. It emphasizes the critical need for data to possess a 'global attribute,' covering trade flows, Global Value Chains (GVC), and cross-country comparisons. Key data types include micro-level customs data (firm-product-destination), cross-country panels (WDI, IMF), and global input-output tables (WIOD/ADB MRIO) for GVC decomposition.

A comprehensive guide for advanced empirical research in open economies. It outlines best practices for establishing causal inference by anchoring identification strategies in external or institutional shocks (e.g., tariffs, trade agreements, exchange rate reforms). The guide emphasizes modern critiques of standard methods like shift-share and gravity models, providing detailed protocols for DID, Bartik decomposition, and IV estimation to meet top-tier academic journal standards.

This comprehensive guide details professional standards for presenting complex empirical economic results (tables and figures) for top-tier journals like The Journal of World Economy. It instructs users on simplifying main regression tables, standardizing notes (clustering, significance), and correctly presenting specialized open-economy objects such as event studies, gravity regressions, and GVC decompositions, ensuring research meets publication quality.

This skill guides the rigorous defense of research design for demographic studies, particularly those linking population dynamics to development outcomes. It assists in selecting and justifying appropriate methods—such as life tables, decomposition, event-history modeling, and age-period-cohort analysis—and critically addresses the identification of causal links between population structure and development progress. It focuses on strengthening the argument by confronting rival hypotheses and establishing methodological rigor, without writing code.

Provides detailed guidelines for authors submitting manuscripts to academic journals, specifically addressing the strict limit of 10 tables and figure panels, along with a 10-page supplementary cap. This guide teaches authors how to critically select, consolidate, and present key research results—such as marginal effects, event studies, or decomposition plots—to ensure every exhibit is self-contained, highly clear, and robust enough to pass expert review.

This guide assists researchers in assessing the suitability of their manuscripts for the World Economic Papers. It covers the journal's focus on international economics, open macro, and global value chains. It provides detailed checks on formatting requirements (abstract, references), assesses methodological suitability (e.g., GVC decomposition), and identifies potential submission pitfalls, ensuring academic rigor before targeting a high-level academic journal.

This skill provides a comprehensive framework for targeting and revising academic manuscripts for the journal World Economic Studies. It analyzes the journal's scope, focusing on globalization, open strategy, international trade, and regional economics. It guides users on required advanced methodologies (e.g., GVC decomposition, panel data), structural mandates, and common submission pitfalls to ensure manuscripts meet high academic standards.

Best practice guide for building responsive Flutter screens and components. Prefer Row, Column, Expanded, Flexible, and Spacer over fixed-size or coordinate-based layouts, manage constraints, avoid overflow, and adapt to viewport changes with nested flex composition.

A comprehensive framework for assessing software supply chain security. It covers generating Software Bill of Materials (SBOM), performing Software Composition Analysis (SCA) on open-source dependencies, auditing CI/CD pipelines, and analyzing container images. This skill helps identify vulnerabilities, ensure build integrity, and verify component provenance across the entire development lifecycle.

Build card games with robust card data, deck/hand/discard zones, draw/shuffle/reshuffle, turn phases, costs, and effect resolution. Ideal for deckbuilders, TCG/CCG, and roguelike deckbuilders; includes compositional patterns and pitfalls to avoid.

Domain knowledge for producing step-by-step Chinese math tutorial videos. Covers problem decomposition, five-part lesson pacing, voiceover narration rules, KaTeX-style formula layout, subtitle timing, and Creator-native implementation using motion clips, audio scripts, and overlay captions.

A comprehensive guide to structuring games in Godot 4.7 using nodes and scenes. Learn best practices for scene composition, safely instantiating reusable PackedScenes at runtime, managing global state with autoload singletons, and preventing common runtime errors like 'node not found' or freed-node access. Essential for robust game development.
