Evidence shows that social network structures drive important economic outcomes. Building on social network theory, this study is the first to analyse the impact of team networks on venture success. Using information about team affiliations for a sample of token-financed startups, we model...

This review is the first one addressing the elephant in the room: the role of networks in venture capital. Entrepreneurs spend days and days in finding the way to get introduced to VCs, while VCs jump from event to event in the aim of spotting the next unicorn. The whole startup and venture...

This paper investigates the role of heterogeneous elasticities of substitution in the US production network in the transmission of supply shocks. We develop and estimate a multi-industry general equilibrium model featuring heterogeneous elasticities of substitution in input demands. Using...

We present a new measure of producers’ aggregate importance in a production economy with input-output linkages. Unlike existing measures, which capture the impact of an isolated TFP shock to a sector on aggregate output, we quantify how a sector amplifies simultaneous shocks to all producers...

This paper empirically examines the effects of financial crises on the organization of production of multinational enterprises. We construct a panel of European multinational networks from 2003 through 2015. We use as a financial shock the increase in risk premia between August 2007 and July...

This paper examines the recent emergence of AI-powered chatbots such as ChatGPT through the lens of the Cognitive Mediation Networks Theory (CMNT), deducing that the introduction of this radically new technology will likely create a new stage of collective cognitive functioning, called...

In this paper, I study how 2007-2009 US financial crisis reshaped the structure of production networks and transmitted shocks from financial and real-estate (F/R) sectors to the entire economy through production networks. Sectors that are more closely related to F/R sectors lose more buyers and...

In this paper, I examine the role of firm lobbying in shaping the structure of US production networks, and its implications for misallocation in production networks across space. Using several instrumental variable strategies, I establish that firms that lobby have more buyers and suppliers, and...

This paper sheds light on the significant role of networks, particularly alumni networks, in venture capital markets. I leverage the instance of a new partner, carrying new alumni networks, entering a venture capital firm as a plausible exogenous shock to the VC's alumni networks. This...

In this paper, we use an analyst’s coverage portfolio as the unit of analysis and argue that the linkage among the portfolio firms can provide useful information for analyst forecasts at the portfolio level. In particular, the geographic overlap in the portfolio firms’ global sales network...
