March 2019The Relationship Dilemma: Organizational Culture and the Adoption of Credit Scoring Technology in Indian Banking
with Prachi Mishra, Raghuram G. Rajan: w25694
Credit scoring was introduced in India in 2007. We study the pace of its adoption by new private banks (NPBs) and state-owned or public sector banks (PSBs). NPBs adopt scoring quickly for all borrowers. PSBs adopt scoring quickly for new borrowers but not for existing borrowers. Instrumental Variable (IV) estimates and counterfactuals using scores available to but not used by PSBs indicate that universal adoption would reduce loan delinquencies significantly. Evidence from old private banks suggests that neither bank size nor government ownership fully explains adoption patterns. Organizational culture, possibly from formative experiences in sheltered markets, explains the patterns of technology adoption.
August 2008Post-Merger Restructuring and the Boundaries of the Firm
with Vojislav Maksimovic, Gordon Phillips: w14291
Mergers and acquisitions are a fast way for a firm to grow. Using plant-level data, we examine how firms redraw their boundaries after acquisitions. We find that there is a large amount of restructuring in a short period following mergers. Acquirers sell 27% and close 19% of acquired plants within three years of the acquisition. Plants in the target's peripheral divisions, especially in industries in which asset values are increasing, and in industries in which the acquirer does not have a comparative advantage, are more likely to be sold by the acquirer. Acquirers with skill in running their peripheral divisions tend to retain more acquired plants. Plants retained by acquirers increase in productivity whereas sold plants do not. The extent of post-merger restructuring activities and their...

July 2002Institutional Allocation In Initial Public Offerings: Empirical Evidence
with Reena Aggarwal, Manju Puri: w9070
We analyze institutional allocation in initial public offerings (IPOs) using a new dataset of US offerings between 1997 and 1998. We document a positive relationship between institutional allocation and day one IPO returns. This is partly explained by the practice of giving institutions more shares in IPOs with strong pre-market demand, consistent with book-building theories. However, institutional allocation also contains private information about first-day IPO returns not reflected in pre-market demand and other public information. Our evidence supports book-building theories of IPO underpricing, but suggests that institutional allocation in underpriced issues is in excess of that explained by book-building alone.
