Transmission des prix
Time-series models estimate how much and how fast changes in world food and energy prices pass into domestic prices, allowing for exchange rates and policies.

Econometrics estimates relationships in trade and price data from observed history. In this field it measures how price shocks pass from world to local markets, how trade responds to policy measures, and how disruptions affect output and prices.
Econometrics applies statistical methods to economic data to estimate relationships, test theories and forecast. It provides empirical evidence on how shocks and policies affect economic outcomes. In trade, resources and supply chains and industry and robotics, econometric evidence estimates how disasters, pandemics and financial shocks affect output, employment and prices. It informs the economic case for réduction des risques. The canonical description is on les STEM Commons.
Time-series models estimate how much and how fast changes in world food and energy prices pass into domestic prices, allowing for exchange rates and policies.
Gravity models and difference-in-differences designs estimate how tariffs, export controls and sanctions change trade flows, including rerouting through third countries.
Event studies relate dated supply disruptions to changes in production and prices in the industries that depend on the disrupted input.
A loss of output in one sector propagates through the technical coefficients to its suppliers and customers, and recovers at the rate you set; the coefficients are teaching values, not national accounts. Teaching model with stated illustrative values, not a prediction.

Datasets and records used by econometrics on this platform, with the role each plays and the label its values carry. Sources are listed in le registre des sources.

Le modèle, ses hypothèses, ses données et son incertitude, sous la forme qu'un scientifique ou un ingénieur vérifierait. Les structures suivent des méthodes publiées. Les valeurs représentées sont illustratives, ce ne sont pas des résultats.
The couplings between the systems in econometrics for trade: signs of influence, a reinforcing and a balancing loop, and cross-links where stress jumps.
Models are assessed through specification tests, robustness checks and out-of-sample performance. Results are compared across datasets and methods.
| Vérifier | Comment c'est fait |
|---|---|
| Pre-trend tests | Treated and comparison flows are checked for parallel trends before measures |
| Robustness to specification | Results are compared across model specifications |
| Structural break tests | Relationships are tested for change over time |
Endogeneity, measurement error and structural change can bias estimates. Relationships may shift under extreme conditions.
Développement économique stewards econometrics for the Consortium and reviews how it is applied across platforms.
