Germany’s economy is so bad even sausage factories are closingIWHThe Economist, January 15, 2026
This paper examines how initial public offerings (IPOs) affect firms' internal organization. We find that IPO firms become more hierarchical and standardized organizations, characterized by additional layers, more managers, smaller control spans, and larger administrative functions. These changes occur mostly in preparation for the IPO and can be only partially explained by growth. IPO firms with greater human capital risk experience larger hierarchical changes. Hierarchical changes help firms standardize employee roles and formalize internal processes. Our results suggest that firms reorganize to reduce their dependence on key individuals' human capital when transitioning to public markets.
We examine the survival prospects, employment profiles, and patient outcomes at private equity (PE)-acquired hospitals. Target hospitals maintain their survival rates while significantly reducing employment and wage expenditures. The number of core medical workers drops temporarily, but returns to its pre-acquisition level in the long run. However, administrative job and wage cuts persist over the long term, particularly at previously nonprofit hospitals. Using proprietary insurance claims data, we find no significant changes in patient demographics or inpatient prices at PE-acquired hospitals. While patient satisfaction declines, there is no evidence of increased patient mortality or readmission rates at PE-acquired hospitals.
This paper examines the effect of going public on firm-level employment. To establish a causal effect, we employ a novel data set of private firms to investigate employment growth in IPO firms relative to a group of firms that file for an IPO but subsequently withdraw their offering. We find that employment increases significantly after going public, and the increase is more pronounced in industries with requirements for highly skilled labor and greater dependence on external finance. Improved ability to undertake acquisitions and a strategic shift toward commercialization, rather than agency problems, explain employment growth. Overall, these results highlight the importance of going public for firms' employment policies.
Hedge fund activists target firms engaging in empire building and improve their future acquisition and divestiture strategy. Following intervention, activist targets make fewer acquisitions but obtain substantially higher returns by avoiding large and diversifying deals and refraining from acquisitions during merger waves. Activist targets also increase the pace of divestitures and achieve higher divestiture returns than matched non-targets. Activists curtail empire building through the removal of empire building chief executive officers (CEOs), compensation based incentives, and appointment of new board members. Our findings highlight an important channel through which activists improve efficiency and create shareholder value.
Venture capitalists (VCs) often serve on the board of mature public firms long after their initial public offering (IPO), even for companies that were not VC-backed at the IPO. Board appointments of VC directors are followed by increases in research and development intensity, innovation output, and greater deal activity with other VC-backed firms. VC director appointments are associated with positive announcement returns and are followed by an improvement in operating performance. Firms experience higher announcement returns from acquisitions of VC-backed targets following the appointment of a VC director to the board. Hence, in addition to providing finance, monitoring and advice for small private firms, VCs play a significant role in mature public firms and have a broader influence in promoting innovation than has been established in the literature.
We examine M&A transactions between firms with current board connections and find that acquirers obtain higher announcement returns in transactions with a first-degree connection where the acquirer and the target share a common director. Acquirer returns are also higher in transactions with a second-degree connection where one acquirer director and one target director serve on the same third board. Our results suggest that first-degree connections benefit acquirers with lower takeover premiums while second-degree connections benefit acquirers with greater value creation. Overall, we provide new evidence that board connectedness plays important roles in corporate investments and leads to greater value creation.
This article studies mergers between competing firms and shows that while such mergers reduce the level of product market competition, they may have an adverse effect on employee incentives to innovate. In industries where value creation depends on innovation and development of new products, mergers are likely to be inefficient even though they increase the market power of the post-merger firm. In such industries, a stand-alone structure where independent firms compete both in the product market and in the market for employee human capital leads to a greater profitability. Furthermore, our analysis shows that multidivisional firms can improve employee incentives and increase firm value by reducing firm size through a spinoff transaction, although doing so eliminates the economies of scale advantage of being a larger firm and the benefits of operating an internal capital market within the firm. Finally, our article suggests that established firms can benefit from creating their own competition in the product and labor markets by accommodating new firm entry, and the desire to do so is greater at the intermediate stages of industry/product development.
This paper studies the relation between firm investment in general human capital, new firm creation and financial development for new firm financing, such as the existence of a venture capital industry. On one hand, firm investment in general human capital leads employees to generate new innovative ideas for starting their own firm. Since employees need a venture capitalist to start their new firm, firm investment in general human capital encourages the creation of venture capitalists by increasing the need for their services, such as providing advice and monitoring. On the other hand, as new firm financing becomes available, firms' willingness to invest in general human capital increases, and as a by-product, the creation of employee-founded and venture capital-backed new firms increases in the economy. Hence, our model provides a rational explanation for the emergence of new firms created by employees of established firms, which represents one of the most common type of new firms in many industries.
Newly public firms make acquisitions at a torrid pace. Their large acquisition appetites reflect the concentration of initial public offerings (IPOs) in mergers and acquisitions-(M&A-) intensive industries, but acquisitions by IPO firms also outpace those by mature firms in the same industry. IPO firms' acquisition activity is fueled by the initial capital infusion at the IPO and through the creation of an acquisition currency used to raise capital for both cash- and stock-financed acquisitions along with debt issuance subsequent to the IPO. IPO firms play a bigger role in the M&A process by participating as acquirers than they do as takeover targets, and acquisitions are as important to their growth as research and development (R&D) and capital expenditures (CAPEX). The pattern of acquisitions following an IPO shapes the evolution of ownership structure of newly public firms.
An initial public offering (IPO) can often provide a powerful stimulus to private companies seeking to pursue an acquisition-driven growth strategy. Based on a comprehensive analysis of U.S. IPOs, the authors show that newly public companies are prolific acquirers. Over 30% of companies conducting an IPO make at least one acquisition in their IPO year, and the typical IPO firm makes about four acquisitions during its first five years as a public company. IPOs facilitate M&A not only by providing infusions of capital but also by creating ongoing access to equity and debt markets for cash-financed deals. In addition, IPOs create an acquisition currency that can prove valuable in stock-financed deals when the shares are attractively priced. The authors also argue that IPOs improve the ability of companies to conduct M&A by resolving some of the valuation uncertainty facing privately held companies.
