Formally test for difference in effect sizes between attribute levels

Dear Thomas,

I have a question about how to formally test whether estimates for two attribute levels within one dimension are significantly different from each other. E.g., in the example below, is the estimated effect for a person from Iraq significantly different from the effect size for a person coming from China?

Thank you!

## load package
library("cregg")

## code goes here
data("immigration")
# estimating AMCEs with constraints
x <- amce(immigration, ChosenImmigrant ~ Gender + ReasonForApplication * CountryOfOrigin,
     id = ~CaseID)
plot(x)
