CI, confidence interval; SD, standard deviation.
a Mixed logit model estimated using Stata’s mixlogit command and 500 Halton draws.
b The coefficient (β) represents the mean relative utility of each attribute conditional on other attributes in a choice set, while the standard deviation of the random coefficients reflects the degree of heterogeneity among respondents in the utility of a given attribute.
c Continuous variable; the coefficient represents the magnitude of increase in utility for every 10% increase in salary.
d Compared with no allowance for children’s education.
e Compared with basic infrastructure, equipment and supplies.
f Compared with unsupportive workplace and management.
g Compared with study leave after at least 5 years.
h Compared with basic housing.
i Compared with no utility car.[an error occurred while processing this directive]
