This paper considers the vertical implications of horizontal diversification. Many studies have documented organizational problems following corporate diversification. We propose that selective vertical dis-integration ' shifting asset ownership to agents ' can mitigate rent-seeking and coordination failures in the diversified firm. We test this proposition in a particularly simple setting that allows us to isolate the effects of interest and control for the likely endogeneity of diversification: taxi fleets that diversify into the limousine, or black car, segment following a wave of entry deregulation in the early 1990s. The results show that taxi fleets are substantially more likely to use owner-operator drivers following diversification. Moreover, diversified fleets that use a greater share of owner operators are more productive than diversified fleets that own most of their vehicles. We interpret these findings as evidence that firms re-organize in response to the challenges of diversification, and that there are causal links between the horizontal and vertical boundaries of the fleet.

Diversification, Organizational Adjustment and Firm Performance: Evidence from Microdata
October 2007
Working Paper Number:
CES-07-29
This paper proposes that diversification taxes firms' existing organizational systems by altering routines, formal contract structures and strategies. I test the proposition that organizational adjustment costs associated with diversification erode incumbent competitive advantage, using novel microdata on taxicab firms from the Economic Census. The tests exploit exogenous local characteristics of taxi markets to identify the impact of diversification on firm organization and performance. Supporting the contention that diversification leads to organizational adjustments, the results show that diversifying firms are less likely to adopt computerized dispatching systems for their taxicabs and make significant changes in their formal contract structures governing asset ownership. Consistent with the theory, diversification is associated with falling taxi productivity. Comparing the productivity of diversified and focused start-ups and incumbent firms reveals that the organizational change component of diversification accounts for an 18% decrease in paid ride-miles per taxi. The results support the core contention of the paper that diversification taxes firms' existing organizational capital.

Information Technology, Capabilities and Asset Ownership: Evidence from Taxicab Fleets
November 2009
Working Paper Number:
CES-09-39
We examine how information technology (IT) influences asset ownership through its impact on firms' and agents' capabilities. In particular, we propose that when IT is a substitute for agents' industry-specific human capital, IT adoption leads to increased vertical integration. We test this prediction using micro data on vehicle ownership patterns from the Economic Census during a period when computerized dispatching systems were first adopted by taxicab firms. The empirical tests exploit exogenous variation in local market conditions, to identify the impact of dispatching technology on firm asset ownership. The results show that firms increase the proportion of taxicabs owned by 12% when they adopt new computerized dispatching systems. The findings suggest that firms increasingly vertically integrate when they acquire resources that substitute for their agents' capabilities.

Intra-Firm Spillovers? The Stock and Flow Effects of Collocation
January 2015
Working Paper Number:
CES-15-01
We examine the impact of collocation on local within-firm performance, or intra-firm spillovers, by decomposing spillovers into one-time stock and recurring flow effects. Stock effects include one-time learning effects. Flow effects include ongoing resource sharing as well as cannibalization. Using data on the population of U.S. hotels and restaurants from 1977-2007, we exploit changes in the number of collocated establishments owned by the same firm to estimate the relative importance of stock and flow benefits. We find that collocation improves the productivity of new and existing establishments by 1-2%, even when correcting for endogenous sorting into collocation. The results, in conjunction with our field work, suggest that collocation generally facilitates the transfer of knowledge within the firm, but that flow effects of collocation are more sensitive to the broader economic environment.

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.

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.

Cementing Relationships: Vertical Integration, Foreclosure, Productivity, and Prices
December 2008
Working Paper Number:
CES-08-41
This paper empirically investigates the possible market power effects of vertical integration proposed in the theoretical literature on vertical foreclosure. It uses a rich data set of cement and ready-mixed concrete plants that spans several decades to perform a detailed case study. There is little evidence that foreclosure is quantitatively important in these industries. Instead, prices fall, quantities rise, and entry rates remain unchanged when markets become more integrated. These patterns are consistent, however, with an alternative efficiency-based mechanism. Namely, higher productivity producers are more likely to vertically integrate and are also larger, more likely to survive, and charge lower prices. We find evidence that integrated producers' productivity advantage is tied to improved logistics coordination afforded by large local concrete operations. Interestingly, this benefit is not due to firms' vertical structures per se: non-vertical firms with large local concrete operations have similarly high productivity levels.

Evolving Property Rights and Shifting Organizational Forms: Evidence From Joint-Venture Buyouts Following China's WTO Accession
March 2013
Working Paper Number:
CES-13-05
China's WTO accession offers a rare opportunity to observe multinationals' response to changes in property rights in a developing country. WTO accession reduced incentives for joint ventures while reducing constraints on wholly owned foreign subsidiaries. Concomitant with these changes was a more liberal investment environment for indigenous investors. An adaptation of Feenstra and Hanson's (2005) property rights model suggests that higher the productivity and value added of the joint venture, but the lower its domestic sales share, the more likely the venture is to be become wholly foreign owned following liberalization. Theory also suggests that an enterprise with lower productivity but higher value added and domestic sales will be more likely to switch from a joint venture to wholly domestic owned. Using newly created enterprise-level panel data on equity joint ventures and changes in registration type following China's WTO accession, we find evidence consistent with the property rights theory. More highly productive firms with higher value added and lower domestic sales shares are more likely to become wholly foreign owned, while less productive firms focused on the Chinese market are more likely to become wholly domestic owned rather than remain joint ventures. In addition to highlighting the importance of incomplete contracts and property rights in the international organization of production, these results support the view that external commitment to liberalization through WTO accession influences multinational and indigenous firms' behavior.

Cementing Relationships: Vertical Integration, Foreclosure, Productivity, and Prices
July 2006
Working Paper Number:
CES-06-21
This paper looks at the reasons for and results of vertical integration, with specific regard to its possible effects on market power as proposed in the theoretical literature on foreclosure. It uses a rich data set on producers in the cement and ready-mixed concrete industries over a 34- year period to perform a detailed case study. There is little evidence that foreclosure effects are quantitatively important in these industries. Instead, prices fall, quantities rise, and entry rates remain unchanged when markets become more integrated. We suggest an alternative mechanism that is consistent with these patterns and provide additional evidence in support of it: namely, that higher productivity producers are more likely to vertically integrate, and as has been documented elsewhere, are also larger, more likely to grow and survive, and charge lower prices. We explore possible sources of vertically integrated producers' productivity advantage and find that the advantage is tied to firm size, possibly in part through improved logistics coordination, but not to several other possible explanations.

Residual Claims and Incentives in Restaurant Chains
July 2006
Working Paper Number:
CES-06-18
I examine the relationship between ownership and production activities using a new dataset of restaurant chains. Production in restaurant chains provides an opportunity to examine the effects of residual claims on incentives because production is decentralized and fairly uniform across restaurants in the same chain. Yet the allocation of residual claims varies between company-owned and franchised units, affecting the strength of incentives for restaurantlevel activities. The decision to own or franchise each restaurant reflects the value of either withholding or allocating residual claims for performing these activities. I find that more complex production activities are systematically correlated with company ownership. Onsite food production raises the likelihood of company ownership by 28% relative to offsite food production. Table service raises the likelihood of company ownership by 26% relative to counter service. The results are not consistent with straightforward effort-promoting effects of residual claims in simple principal agent models. They are consistent with the view that residual claims can generate unbalanced incentives across diverse tasks.

Delegation in Multi-Establishment Firms: The Organizational Structure of I.T. Purchasing Authority
October 2010
Working Paper Number:
CES-10-35
A rare large-scale empirical study of delegation within firms, this paper investigates how decision rights over information technology investments are allocated within multi-establishment firms. The core results indicate that a relatively high contribution to firm sales is highly correlated with authority being delegated to the local establishment. Firm-wide operational complexity and local information advantages are also associated with local discretion for IT purchases. Certain IT investments are also positively correlated with delegation. On the other hand, significant operational interdependencies evince a positive correlation with centralization, as do productive similarities among establishments. Surprisingly, absolute size of the firm and having a large IT budget are also correlated with centralized IT decision-making. With the exception of these latter effects, the results are consistent with models of organizational design that predict delegation where there is great demand for locally adapted choices and centralization where firm-wide coordination is most important. The findings document and make sense of widespread heterogeneity in decision rights across a range of firm and industry settings ' even among establishments belonging to the same parent firm. Finally, they suggest important considerations for future empirical and theoretical research into the determinants of delegation.
