Access over 800,000 economic time series from FRED's API, covering GDP, employment, inflation, interest rates, regional metrics, and more; ideal for macroeconomic analysis, financial research, policymaking, and forecasting workflows.

Kubesec is an open-source security risk analysis tool that scores Kubernetes resource manifests to identify security misconfigurations, privilege escalation risks, and policy violations. It checks for best practices like immutable root filesystems and non-root execution. Ideal for integrating into CI/CD pipelines, pre-deployment manifest review, or performing security audits.

A rigorous academic tutor specializing in bridging theoretical business and economic models with real-world applications. Covers advanced topics including microeconomics (Game Theory, Market Structures), macroeconomics (GDP, Policy Analysis), corporate finance, accounting principles, and marketing strategies (STP, 4Ps). It uses a Harvard case-method approach, Socratic questioning, and active recall to build deep understanding, ensuring users can apply knowledge to ambiguous business decisions rather than just memorizing definitions.

A comprehensive coach for national and provincial civil service exams (国考/省考). This skill covers both the Administrative Aptitude Test (行测) and Essay Writing (申论), focusing on strategic test-taking, pattern recognition, and deep policy analysis. It also prepares candidates for structured interviews and official document writing, providing skills applicable to government careers globally.

This skill provides a highly rigorous framework for analyzing complex public issues, platform governance, and institutional compliance. It is designed to structure evidence boundaries, assess procedural justice, and track public commitments by synthesizing source ledgers and multiple data points. It is intended as a specialized sub-routine triggered by the main CrossFrame suite, not for standalone use. Key focus areas include source verification, identifying weak signals, and mitigating AI compliance performance risks.

A comprehensive framework for translating reduced-form causal estimates (e.g., elasticity, treatment effects) into explicit policy statements. It guides researchers on building clear welfare, cost-benefit, or optimal-policy models, defining sufficient statistics, and articulating distributional effects, ensuring policy claims are rigorously grounded in empirical data.

This guide outlines rigorous standards for conducting heterogeneity analysis in economic research. It stresses that heterogeneity should not merely involve slicing data by region or size, but must be theoretically driven, linking multiple dimensions (e.g., ownership, financing constraints, industry type) to core economic mechanisms. The analysis must demonstrate significant group differences and clearly connect findings to differential policy implications, elevating the discussion from mere observation to actionable policy science.

This guide provides a rigorous framework for designing and interpreting quantitative case studies in academic manuscripts. It instructs authors on justifying parameter sources (real data, literature, policy), structuring comprehensive experiment matrices (effectiveness, sensitivity, boundaries, context), and moving beyond mere result description to deep mechanism-based analysis.

This comprehensive guide provides a rigorous framework for identifying and testing the causal mechanisms underlying public administration outcomes. It moves beyond merely stating an effect, guiding researchers to detail the specific processes—such as policy execution, attention allocation, or central-local relations—that cause the observed outcome. It covers both quantitative mediation analysis (e.g., causal inference frameworks) and qualitative process evidence gathering, ensuring theoretical grounding and causal rigor in academic manuscripts.

This guide provides rigorous methodology and theoretical frameworks for conducting heterogeneity analysis, particularly for academic manuscripts focused on rural Chinese economies. It outlines criteria for dimension selection (e.g., household endowment, regional environment, policy timing), ensuring theoretical justification, and setting minimum sample size requirements to avoid superficial findings and common pitfalls.

This guide provides an expert framework for advanced econometric analysis, focusing on establishing causal inference in fields like finance and trade. It details best practices for quasi-experimental designs (DID, IV, RDD, DML) and rigorously addresses common endogeneity issues such as policy bias, reverse causality, and anticipation effects, ensuring robust research methodology.

This guide provides rigorous methodologies for conducting mechanism analysis in empirical economics, particularly for submissions to finance and trade journals. It teaches how to open the 'policy black box' by identifying measurable, causal channels (e.g., changes in firm investment, credit flow, or government expenditure) that explain the relationship between a policy shock and an outcome. It covers mediation/moderation techniques and sub-sample comparisons.
