Notably knowledge distance is even more important to households in which both spouses work.
The findings are robust to this; the primary distinction is that knowledge distance has a statistically stronger stabilizing effect for couples composed of at least one college graduate.
As Table 2 shows, the 4 files' distance measures are not pairwise collinear, and we can estimate distinct effects of Knowledge distance and Activities distance, for example.
The single earner sample's estimates find a stronger destabilizing effect for activities distance, and it does not find the dual earner sample's stabilizing effect of knowledge distance.
The same reasoning holds for both R&D and co-authorship networks, where communities of collaborating agents do not depend on their geographical or knowledge distance, but are defined by the subsequent propagation of a (virtual) membership attribute, which is the 'label'label
Other risk factors for default in mainly new patients have been described in other settings, such as health knowledge, distance to treatment centre, and patients' economic status; these could not however be assessed in this study [16], [17], [23].
