We use community detection analysis to investigate the structure of Bengaluru's ICT cluster's inter-organizational network during the period 2015–2017. Building on the knowledge sourcing literature, we conjecture that cluster firms primarily build knowledge-seeking horizontal linkages with technologically similar companies, and that this splits the network into multiple technological communities within which firms are tightly connected, but between which linkages are scarce. We further propose that community-spanning firms which build horizontal linkages that bridge technological communities are more likely to conduct radical innovation than their peers. We finally argue that no relation exists between technological proximity and community formation in the network of vertical buyer-supplier relations. Using a voltage-based algorithm for community discovery, we draw empirical support for these predictions. We discuss the implications of our findings for Bengaluru's upgrading potential.

We provide strong support for the underappreciated expected earnings hypothesis of a negative correlation between aggregate stock returns and earnings. For 1970–2000, our powerful modeling strategy incorporating macroeconomic information reveals that aggregate returns are significantly and negatively correlated with expected aggregate earnings changes but uncorrelated with unexpected aggregate earnings changes. However, this negative correlation changes after 2000, perhaps from heightened volatility or accounting changes. We also show that underlying macroeconomic information explains the power of aggregate earnings to predict future gross domestic product growth.

India began the process of market liberalization that opened it to significant interactions with the world economy in 1991. In this essay, we provide an overarching view of the country's journey toward integration with the global innovation and entrepreneurship network. Major nodes in this global network have two major components that may be metaphorically referred to as ‘pillars and ivy’. Globally connected multinational enterprises (MNEs) form the pillars. Agile startups are the ivy, and their success (metaphorically, the height to which they can climb) depends on their symbiotic connections with the pillar MNEs. Both components are essential and reinforce each other. Without MNEs, the scaling of startups is hampered. Without a vibrant population of startups, MNEs’ interest in a location remains driven by cost, rather than capability and creativity. MNEs (mainly foreign) provided the initial sparks for the formation of the Indian innovation and entrepreneurship ecosystem. We chart the subsequent growth of India's startups. They began in the information technology (IT) sector but now cover a much wider range of industries. Today, India's innovation and entrepreneurship ecosystem is one of the largest in the world, with global integration in terms of technology, financing, human capital, and administration.
