Risks Factors that Matter: Textual Analysis of Risk Disclosures for the Cross-Section of Returns

Working Papers

I introduce risk factors that not only explain the cross-section of returns, but also unambiguously represent economic risk for the firms, are interpretable, and come directly from the companies. I exploit machine learning and natural language processing techniques to identify from the 10-K annual reports the types of risks that firms face, and to quantify how much each firm is exposed to each type of risk.Read More

Borrow, Buy, and Invest: Complementarity and Substitutability of External Corporate Development Modes

Funded Research Proposal

I aim to contribute to corporate strategy and technology and innovation management literatures by refining the way we think about how firms’ externally accessible resources and capabilities influence those firms’ heterogeneous boundary choices and their resulting outcomes. Read More

The Corporate Parenting Effect, Revisited

Funded Research Proposal

This project considers whether and how corporate headquarters either add value to or destroy value for the subsidiaries operating under their oversight. This question is a foundational one in the field of strategic management and has been debated for several decades. However, researchers have been limited from fully answering it. Read More

Needless Distraction or Font of Knowledge: Understanding the Relationship between Divestitures and Innovation

Funded Research Proposal

Few studies have examined the impact of divestitures on the innovation performance of firms. In particular, little attention has been paid into how the divestiture of firms’ non-core businesses could influence the innovation outcomes of their core businesses. Read More

Make Room! Make Room! A Note on Sequential Spinoffs and Acquisitions

Published Research

In this study, we identify a novel pattern of deal-making activity—spinoffs followed by acquisitions—that has yet to be analyzed in the corporate strategy literature. We present a set of descriptive results showing that firms undertake spinoffs followed by acquisitions at a rate that is too high to be attributable to random chance.Read More

Corporate Spin-Offs and Capital Allocation Decisions

Published Research

This paper investigates how spin-offs affect capital allocation decisions in diversified firms. The sensitivity of capital expenditures to investment opportunities, representing the efficiency of capital allocation decisions, improves when firms undertake spin-offs.Read More

Replicating the Multinationality-Performance Relationship: Is There an S-Curve?

Published Research

Our study examines the relationship between a firm’s multinationality and its performance. In a much-cited study, Lu and Beamish (2004) found evidence of an S-shaped relationship—with firm performance first decreasing, then increasing, then decreasing again as firms internationalized—in a sample of Japanese firms from 1986 to 1997.Read More

The Evolution of Alliance Portfolios: The Case of Unisys

Published Research

How do alliance portfolios evolve? We develop grounded theory based on Unisys’ case, which reveals how exogenous technological changes at the industry level and shifts in a firm’s strategy shape the composition of partners and the nature of alliance relationships.Read More

Why Do Firms Divest?

Published Research

In this paper, I examine how lower-cost production and new market opportunities influence the divestment decisions of firms. I argue that lower-cost production and new market opportunities in foreign markets can provide a better use of existing firm resources and posit that these opportunities are likely to influence firm divestment of home-country operations.Read More
