Ekonometrika untuk perdagangan

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.

What econometrics does here.

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 pengurangan risiko. The canonical description is on STEM Commons.

Transmisi harga

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.

Effects of trade measures

Gravity models and difference-in-differences designs estimate how tariffs, export controls and sanksi change trade flows, including rerouting through third countries.

Disruption impacts on output

Event studies relate dated supply disruptions to changes in production and prices in the industries that depend on the disrupted input.

03Simulator

Guncangan melalui ekonomi masukan-keluaran.

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.

06Validasi

Cara hasil diperiksa.

Models are assessed through specification tests, robustness checks and out-of-sample performance. Results are compared across datasets and methods.

PemeriksaanCara pelaksanaannya
Pre-trend testsTreated and comparison flows are checked for parallel trends before measures
Robustness to specificationResults are compared across model specifications
Structural break testsRelationships are tested for change over time

Endogeneity, measurement error and structural change can bias estimates. Relationships may shift under extreme conditions.
