The TEA model relies on the Shared Socioeconomic Pathways (SSPs) database as a reference for the economic growth scernarios. Most applications are based on the GDP projections of the SSP2 scenario12. In the baseline, Total-Factor Productivity (TFP) is endogenoulsy target to meet the GDP. Labor supply follows SSP2 population growth rates3. Land productivity is assumed to increase exogenously, but no increase is assumed for labor and capital productivity. Demand for goods and services grows as income and yield increase. Baseline additional adjustments (structural changes) in long-term demand were made when necessary, usually, based on estimated curves relating GDP per capita and demand share. For instance, the shares of food and agriculture goods in final demand were adjusted to capture long-term structural changes in preferences.
