We empirically examine whether greater firm diversity results in the inefficient allocation of capital. Using both COMPUSTAT and the Annual Capital Expenditure Survey (ACES) we find firm diversity to be negatively related to the efficiency of investment. However once we distinguish between capital expenditure for structures and equipment, we find that while firms do inefficiently allocate capital for equipment, they efficiently allocate capital for structures. These results suggest that when the decision will have long-lasting repercussions, headquarters will, more often than not, make the correct choice.

Efficiency Implications of Corporate Diversification: Evidence from Micro Data
November 2006
Working Paper Number:
CES-06-26
In this study, we contribute to the ongoing research on the rationales for corporate diversification. Using plant-level data from the U.S. Census Bureau, we examine whether combining several lines of business in one entity leads to increased productive efficiency. Studying the direct effect of diversification on efficiency allows us to discern between two major theories of corporate diversification: the synergy hypothesis and the agency cost hypothesis. To measure productive efficiency, we employ a non-parametric approach'a test based on Varian's Weak Axiom of Profit Maximization (WAPM). This method has several advantages over other conventional measures of productive efficiency. Most importantly, it allows one to perform the efficiency test without relying on assumptions about the functional form of the underlying production function. To the best of our knowledge, this study is the first application of the WAPM test to a large sample of non-financial firms. The study provides evidence that business segments of diversified firms are more efficient compared to single-segment firms in the same industry. This finding suggests that the existence of the so-called 'diversification discount' cannot be explained by efficiency differences between multi-segment and focused firms. Furthermore, more efficient segments tend to be vertically integrated with others segments in the same firm and to have been added through acquisitions rather than grown internally. Overall, the results of this study indicate that corporate diversification is value-enhancing, and that it is not necessarily driven by managers' pursuit of their private benefits.

Discretionary Disclosure in Financial Reporting: An Examination Comparing Internal Firm Data to Externally Reported Segment Data
September 2009
Working Paper Number:
CES-09-28
We use confidential, U.S. Census Bureau, plant-level data to investigate aggregation in external reporting. We compare firms' plant-level data to their published segment reports, conducting our tests by grouping a firm's plants that share the same four-digit SIC code into a 'pseudo-segment.' We then determine whether that pseudo-segment is disclosed as an external segment, or whether it is subsumed into a different business unit for external reporting purposes. We find pseudo-segments are more likely to be aggregated within a line-of-business segment when the agency and proprietary costs of separately reporting the pseudo-segment are higher and when firm and pseudo-segment characteristics allow for more discretion in the application of segment reporting rules. For firms reporting multiple external segments, aggregation of pseudo-segments is driven by both agency and proprietary costs. However, for firms reporting a single external segment, we find no evidence of an agency cost motive for aggregation.

The Real Effects of Hedge Fund Activism: Productivity, Risk, and Product Market Competition
July 2012
Working Paper Number:
CES-12-14
This paper studies the long-term effect of hedge fund activism on the productivity of target firms using plant-level information from the U.S. Census Bureau. A typical target firm improves its production efficiency within two years after activism, and this improvement is concentrated in industries with a high degree of product market competition. By following plants that were sold post-intervention, we also find that efficient capital redeployment is an important channel via which activists create value. Furthermore, our analyses demonstrate that measuring performance using the Compustat data is likely to lead to a downward bias because target firms experiencing greater improvement post-intervention are also more likely to disappear from the Compustat database. Finally, consistent with recent work in asset-pricing linking firm investment decisions and expected returns, we show how changes to target firms' productivity are associated with a decline in systemic risk, particularly in competitive industries.

Diversification Discount or Premium? New Evidence from BITS Establishment-Level Data
December 2001
Working Paper Number:
CES-01-13
This paper examines whether the finding of a diversification discount in U.S. stock markets is only a data artifact. Segment data may give rise to biased estimates of the value effect of diversification because segments are defined inconsistently across firms, and that inconsistency does not occur at random. I use a new establishment-level database that covers the whole U.S. economy (BITS) to construct business units that are more consistently and objectively defined across firms, and thus more comparable. Using a common methodological approach on a sample of firms which exhibit a diversification discount according to segment data, I find that, when BITS data are used, diversified firms actually trade at a significant average premium. The premium is robust to variations in the method, sample, business unit definition, and measures of excess value and diversification used.

The Human Factor in Acquisitions: Cross-Industry Labor Mobility and Corporate Diversification
September 2015
Working Paper Number:
CES-15-31
Internal labor markets facilitate cross-industry worker reallocation and collaboration, and the resulting benefits are largest when the markets include industries that utilize similar worker skills. We construct a matrix of industry pair-wise human capital transferability using information obtained from more than 11 million job changes. We show that diversifying acquisitions occur more frequently among industry pairs with higher human capital transferability. Such acquisitions result in larger labor productivity gains and are less often undone in subsequent divestitures. Moreover, acquirers retain more high skill workers and they exploit the real option to move workers from the target firm to jobs in other industries inside the merged firm. Overall, our results identify human capital as a source of value from corporate diversification and provide an explanation for seemingly unrelated acquisitions.

LBOs, Debt And R&D Intensity
February 1993
Working Paper Number:
CES-93-03
This paper details the impact of debt on R&D intensity for firms undergoing a leveraged buyout (LBO). We develop seven hypotheses based on capital market imperfection theories and agency theory. To test these hypotheses, we compare 72 R&D performing LBOs with 3329 non-LBO control observations and 126 LBOs with little or no R&D expenditures. The regressions yield four statistically significant major findings. First, pre-LBO R&D intensity is roughly one-half of the overall manufacturing mean and two-thirds of the firm's industry mean. Second, LBOs cause R&D intensity to drop by 40 percent. Third, large firms tend to have smaller LBO- related declines in R&D intensity. Fourth, R&D intensive LBOs outperform both their non-LBO industry peers and other LBOs without R&D expenditures.

The Financial Performance of Whole Company LBOs
November 1993
Working Paper Number:
CES-93-16
Using the previously untapped Census Quarterly Financial Report (QFR) file, we explored the financial performance of a large unbiased sample of 209 leveraged buyouts (LBOs) and 48 going private transactions occurring between 1978 and 1989. Our principal findings are: First, we confirm previous work showing that LBOs substantially increase operating performance and reduce taxes. Second, we find that the operating performance gains are sustained for three years. However, there is a significant drop in performance in the fourth and fifth years. Performance in these years is not significantly above the pre- LBO level. Third, total debt to assets displays only a slight insignificant downward trend. Thus, high debt remains after the drop in performance. Fourth, we find evidence that the performance gains decline in the mid- to late 1980s, with the exception of 1989. Fifth, the data suggest that LBOs target typical firms. The only significant pre-LBO firm characteristic was lower bank debt relative to nonbank debt. Sixth, we identify a number of factors that differentiate LBO performance. Performance tends to be higher when pre-LBO performance is low and the firm is classified as a large R&D performer. Conversely, management buyouts and buyouts involving extensive restructuring did not outperform other buyouts. Finally, we observe a clear linkage between debt and performance, since nonleveraging going-private deals have significantly lower performance than LBOs.

R&D or R vs. D?
Firm Innovation Strategy and Equity Ownership
April 2020
Working Paper Number:
CES-20-14
We analyze a unique dataset that separately reports research and development expenditures
for a large panel of public and private firms. Definitions of 'research' and 'development' in this dataset, respectively, correspond to definitions of knowledge 'exploration' and 'exploitation' in the innovation theory literature. We can thus test theories of how equity ownership status relates to innovation strategy. We find that public firms have greater research intensity than private firms, inconsistent with theories asserting private ownership is more conducive to exploration. We also find public firms invest more intensely in innovation of all sorts. These results suggest relaxed financing constraints enjoyed by public firms, as well as their diversified shareholder bases, make them more conducive to investing in all types of innovation. Reconciling several seemingly conflicting results in prior research, we find private-equity-owned firms, though not less innovative overall than other private firms, skew their innovation strategies toward development and away from research.

HUMAN CAPITAL LOSS IN CORPORATE BANKRUPTCY
July 2013
Working Paper Number:
CES-13-37
This paper quantifies the 'human costs of bankruptcy' by estimating employee wage losses induced by the bankruptcy filing of employers using employee-employer matched data from the U.S. Census Bureau's LEHD program. We find that employee wages begin to deteriorate one year prior to bankruptcy. One year after bankruptcy, the magnitude of the decline in annual wages is 30% of pre-bankruptcy wages. The decrease in wages persists (at least) for five years post-bankruptcy. The present value of wage losses summed up to five years after bankruptcy amounts to 29-49% of the average pre-bankruptcy market value of firm. Furthermore, we find that the ex-ante wage premium to compensate for the ex-post wage loss due to bankruptcy can be of similar magnitude with that of the tax benefits of debt.

Data in Action: Data-Driven Decision Making in U.S. Manufacturing
January 2016
Working Paper Number:
CES-16-06
Manufacturing in America has become significantly more data-intensive. We investigate the adoption, performance effects and organizational complementarities of data-driven decision making (DDD) in the U.S. Using data collected by the Census Bureau for 2005 and 2010, we observe the extent to which manufacturing firms track and use data to guide decision making, as well as their investments in information technology (IT) and the use of other structured management practices. Examining a representative sample of over 18,000 plans, we find that adoption of DDD is earlier and more prevalent among larger, older plants belonging to multi-unit firms. Smaller single-establishment firms adopt later but have a higher correlation with performance than similar non-adopters. Using a fixed-effects estimator, we find the average value-added for later DDD adopters to be 3% greater than non-adopters, controlling for other inputs to production. This effect is distinct from that associated with IT and other structured management practices and is concentrated among single-unit firms. Performance improves after plants adopt DDD, but not before ' consistent with a causal relationship. However, DDD-related performance differentials decrease over time for early and late adopters, consistent with firm learning and development of organizational complementarities. Formal complementarity tests suggest that DDD and high levels of IT capital reinforce each other, as do DDD and skilled workers. For some industries, the benefits of DDD adoption appear to be greater for plants that delegate some decision making to frontline workers.
