Three essays on social networks and entrepreneurship

This thesis explores in three essays if, how, and why social relationships have a bearing on outcomes in the entrepreneurial process. The first essay attempts to determine which mechanism drives the children of business owners to expect to become and actually enter business ownership themselves. Results are inconsistent with arguments asserting that the intergenerational correlation is a result of: the transmission of human capital or financial capital; the expectation of inheriting a business; a heightened awareness of the viability of business ownership; or preferences for having lots of money. Findings are consistent with the notion that the intergenerational correlation in business ownership is a result of shared preferences/traits such as overconfidence. Social capital is a multifaceted concept. However, a disproportionate share of network research has been dedicated to the theorization and transmission of one form of social capital information. Indeed, network structure is generally considered a proxy for information flow. This assumption is often reasonable. In important contexts of social and economic interest it can, however, be misleading. This essay draws attention to the specific "substances of advantage" that flow to different types of actors across varied dyadic ties. Two concepts-(non)rivalry and (non)excludability-are introduced to explain why certain substances of advantage are (not) transmitted across different types of dyadic ties to actors with distinct categorical characteristics.
