Multivariate Tobit models are estimated using German cross?sectional data to test whether strategic complementarities exist between expenditures in four different types of ICT?components. If two ICT?components are complements, they are correlated (provided that agents act rationally)....

We implement an endogeneous switching-regression model for labour productivity and firms' decision to use business-to-business (B2B) e-commerce. Our approach allows B2B usage to affect any parameter of the labour productivity equation and to properly take account of strategic complementarities...
