The size of export elasticities affects how changes in prices impact a country's export demand. This, in turn, influences measures of welfare like real consumption or GDP. The researchers used Computable General Equilibrium (CGE) models to study this relationship. They found that the scale of export elasticities can significantly impact the results of these models, which can ultimately determine whether a policy change is beneficial or harmful for an economy. Understanding and accurately estimating these elasticities is crucial for making informed decisions about economic policies.
