Research subject
Economic growth is examined through the sources of demand, the composition of production and the capacity to sustain expansion.
Headline GDP can conceal an important change in the basis of growth. Household consumption, fixed investment, government demand, inventories and external trade have different implications for future activity. Research examines their interaction and distinguishes a contribution to one quarter’s growth from a durable source of demand.
Productive capacity depends on labor input, the capital stock and productivity. Investment expands capacity only as projects are completed and put to productive use. Participation, skills, infrastructure and the allocation of resources affect the relationship between expenditure today and output tomorrow.
An outlook is therefore a set of conditional judgments. Research identifies which assumptions concern demand and which concern supply, and considers the evidence that would require those judgments to change.
Research Report
American growth must be reconciled across expenditure, industry, and input accounts. Dated official evidence and reproducible examples explain why household demand, investment, and productivity describe different aspects of the same production process.

The September 2026 national-accounts vintage shows why private domestic demand and headline GDP require separate readings. Consumption, fixed investment, inventories and imports provide different evidence about the composition of U.S. growth.

Factory construction measures one stage and one class of industrial investment. The study reconciles construction expenditure, equipment, intellectual property and operating capacity, showing why a building boom cannot be read directly as manufacturing output.

Factory construction measures one stage and one class of industrial investment. The study reconciles construction expenditure, equipment, intellectual property and operating capacity, showing why a building boom cannot be read directly as manufacturing output.
Economy Study
China's expenditure accounts identify immediate purchasers, while production networks reveal the final markets supporting domestic income. Reconciling the two explains why consumption, investment, and export growth create different business exposures.
Economy Study
France's annual accounts show different movements in manufacturing, services, construction, and household demand. Linking expenditure to production explains how domestic services support industrial capacity and why gross output differs from domestic value added.
Economy Study
Canadian output and output per resident answer different economic questions. This study reconciles population, productivity, hours, capital, and household purchasing power, explaining how aggregate expansion can coexist with pressure on average living standards or local capacity.
Economy Study
Brazil's 2025 growth combined rapid agricultural expansion with slower growth in broad services. Separating harvest volumes, commodity prices, household income, and investment reveals how sector-specific gains reach domestic demand and why aggregate growth does not establish uniform momentum.
Economy Study
Saudi non-oil growth can expand private production while retaining links to oil-financed demand. This study separates statistical diversification, customer composition, employment, and external earnings to assess the durability of the expansion.
Comparative Study
American and euro-area quarterly GDP releases commonly use different rate conventions. Reconciliation of annualized and quarter-on-quarter growth establishes the basis for comparison before differences in economic performance can be assessed.
Comparative Study
U.S. and Chinese consumption ratios reflect both household behavior and the allocation of income across sectors. Matched expenditure measures and an explicit accounting bridge distinguish rebalancing, public provision and changes in domestic demand.
Comparative Study
Saudi and UAE diversification measures describe different production, trade, and fiscal boundaries. Official records and an original denominator calculation show why a higher non-oil GDP share does not establish equal diversification of income or public revenue.
Data Note
Chained-dollar expenditure components can fail to sum to real GDP without an accounting error. A reproducible two-good example explains nonadditivity and identifies the measures appropriate for shares and contributions to growth.
Data Note
Nominal sales combine prices and quantities, whereas real output removes price effects within a defined production boundary. A price-volume example explains why Chinese activity indicators cannot be compared by their headline growth rates alone.
Data Note
The euro area's growth rate reflects the relative size of its economies and the construction of its volume accounts. A hypothetical aggregation separates union-wide output growth from the experience of an equally weighted member.
Data Note
Fiscal-year and calendar-year growth cover different quarters. An aligned sequence of output levels demonstrates how the same economic path can generate different annual growth rates without a disagreement about underlying production.
Data Note
GDP per person changes with both aggregate output and population. Exact growth arithmetic distinguishes a larger economy from higher average output and identifies why population timing and matching price measures matter.
Data Note
The non-oil share of nominal output can rise when oil prices fall, even with unchanged production in both sectors. Separate price and volume calculations identify what a structural-diversification claim must establish.
Economic Explainer
Domestic output, national income and disposable income follow different accounting boundaries. A cross-border production example explains when GDP measures local activity and when resident income or purchasing power is the more relevant comparison.
Economic Explainer
Market exchange rates and purchasing-power parities answer different questions about economic size. A common-price example explains the appropriate conversion for domestic production comparisons, external purchasing capacity and international financial obligations.

Real GDP and real domestic income can also answer different questions where trading prices change. International comparisons establish the measure and period before drawing a conclusion about relative performance.
Begin with U.S. domestic demand and the comparison of American and euro-area quarterly growth. The data note on chained-dollar components explains why published real expenditure levels may not add to the aggregate.
