sectorbysector

Sectorbysector is an analytical framework used to examine economic or market activity by breaking it down into individual sectors rather than relying solely on aggregate figures. The approach emphasizes sector-specific performance, risks, and policy effects, and facilitates comparisons across sectors.

The methodology involves defining sectors according to recognized industry classifications, collecting sector-level data on output, employment, investment, profitability, and other indicators, and applying metrics such as growth rates, productivity, and leverage. Analysts may normalize data to enable cross-country or cross-time comparisons and use benchmarking, scoring, or scenario analysis to evaluate outcomes under different assumptions.

Applications of Sectorbysector include investment analysis, portfolio construction, and risk management through sector rotation. In public policy and macroeconomic forecasting, it supports targeted interventions, impact assessments, and the evaluation of sector-specific shocks (for example, commodity price swings or regulatory changes) on overall economy.

Advantages of the approach include increased granularity, better identification of sector-led growth or vulnerability, and more precise benchmarking. Limitations include data gaps, inconsistencies in sector classifications, intersector spillovers that blur boundaries, and the complexity of reconciling sector results with aggregate measures.

Sectorbysector is used in finance, economics, and policy research. It is closely related to sector analysis, value-chain mapping, and input-output analysis, and may be combined with regional or firm-level data to enrich insights.
