st: should I concern the endogeneity problem

[Gordon <gaog66@gmail.com>]

Hi,

I am estimating a model:

Y = X1 + X2 + X1*X2

I am confident that X1 and X2 are exogenous to Y, however it is likely
that X1 is influenced by X2. In this case, should I worry about any
endogeneity?

Thanks for your insights!
