Abstract: | Abstract: The impact of social networks on features of embedded couples, like, for instance, marital stability, has been discussed in sociology for about half a century. However, empirical findings are little cumulative and lack a theoretical integration. We present a framework for the analysis of couples, where their social embeddedness is conceptualized as social capital. Two aspects or dimensions of social capital are distinguished. On the one hand social capital can be seen as a property of a collective system of actors, which makes it a collective good, causing positive external effects (system capital). On the other hand it can be regarded as the pool of valuable resources or services controlled by others, that can be mobilized via social relations (relational capital). These two dimensions are roughly corresponding to the distinct views of social capital in literature. In our judgment, both aspects of social capital are important for marital stability.
