One aspect in which non‐financial corporations (NFCs) are said to be financialized is that they have been increasingly engaged in financial accumulation from which they derive a growing proportion of financial income. This is what we call the financial turn of accumulation hypothesis. In this article, we show that the evidence used to sustain it, in the U.S. setting, has to be reconsidered. Our findings show that, contrary to the financial turn of accumulation hypothesis, financial income averages 2.5% of NFCs’ total income since the 1980s, oscillating since the beginnings of the 1990s until 2005 and then declining. In terms of assets, some of the alleged financial assets might actually reflect other activities in which NFCs have been increasingly engaged, such as tax avoidance, internationalization of production, activities refocusing and M&As.  相似文献

Employees are increasingly given control over how they learn, and their choices for training are diverse and varied, yet employees must balance competing demands. On one hand, they are expected to be increasingly efficient in their current job duties – on the other hand, they are expected to develop new skills and competencies that enable them to adapt and respond to changing job demands. Drawing from the organizational learning literature, we propose a model of worker and work characteristics that inform choices between two mindsets related to learning at work. The first mindset is exploration, or the pursuit of learning outside one’s current knowledge domain; the second mindset is exploitation, the refinement/deepening of one’s existing knowledge stock focusing on the task at hand. We further propose that these strategic choices, or trade-offs, influence employee learning and performance in unique ways, with different implications for both routine and adaptive performance. Finally, we incorporate the notions of feedback loops and risk assessments that influence ongoing decisions between exploration and exploitation mindsets. Recommendations for future research and extensions of the theoretical model are also proposed.  相似文献

Private equity performance, both for buyouts and venture capital, has been highly cyclical: periods of high fundraising have been followed by periods of low performance. Despite this seemingly predictable variation, we find modest gains, at best, to pursuing realistic, investable strategies that time capital commitments to private equity. This occurs, in part, because investors can only time their commitments to funds; they cannot time when commitments are called or when investments are exited. There is a high degree of time-series correlation in net cash flows even across commitment strategies that allocate capital in a very different manner over time.  相似文献

ABSTRACT

Using the theory of indigenous alternatives and a benchmark of indigenous financial reporting expectations, this paper examines the challenges to accountable governance of the nine provincial governments of the Solomon Islands for the years 1998 to 2017. Every provincial government consistently received disclaimed or qualified opinions from the state auditor. The author explains why the regional development of all provinces of the Solomon Islands could be improved if rudimentary forms of financial reporting were to be addressed.  相似文献

The past 15 years have seen the emergence of large infusions of private capital at levels previously accessible only in public markets. One direct effect of these non‐public fundraisings is the spawning of private entities with market valuations reaching $1 billion, thereby achieving the status of unicorns. As the authors reported in an earlier study, by the end of 2015, there were 142 unicorns with an aggregate value exceeding $500 billion. The conviction of many investors and managers at that time was that these companies could best create value by staying private, often by adopting governance structures focused on creating superior operating performance. It was also widely believed that unicorns would remain outside the public markets longer and succeed in attracting even more private capital, thereby enabling their investors to capture a greater share of the increase in company value. In this study, the authors examine how the characteristics and dynamics of “the blessing” have changed in the past five years. Despite the widespread view that the valuations and private financing trend fueling this market were not sustainable, the authors report that by March 2020, the “net” number of unicorns had grown from 142 to 464, a number that doesn't reflect the transformation of over half of the 2015 sample through acquisition or public offering and their replacement by new unicorns. Further, the cumulative market valuation of unicorns more than doubled from $500 billion to $1.37 trillion, representing growth far greater than that in the public equity markets (some 26% per annum, as compared to 9% for the S&P 500) over the same period—and the blessing has become more diversified, both in terms of industry and geographical location. The authors also consider what happens when unicorns “graduate” to a different organizational form by means of an IPO, private buyout, or business failure. Analyzing the 107 firms that departed the sample between 2015 and 2020, the authors report that the average lifespan of a unicorn from its founding date to its exit date has been 9.5 years, indicating that such firms indeed remain privately owned for a longer time than in the past. Additionally, the study finds that the founders and initial investors in unicorns have fared quite well, cashing out their initial investment at almost six times invested capital, on average. These private investment performance metrics have been significantly higher than the returns to public shareholders in the same firms during the post‐IPO period, signifying that unicorn investors have captured much more of the value created in the company's growth phase than public stockholders.  相似文献

In this study we use the recently mandated risk factor disclosure to examine the spillover effect of the Securities and Exchange Commission (SEC) review of qualitative corporate disclosure. We find that firms not receiving any comment letter (“No‐letter Firms”) modify their subsequent year's disclosures to a larger extent if the SEC has commented on the risk factor disclosure of (i) the industry leader, (ii) a close rival, or (iii) numerous industry peers. We refer to this effect as “spillover.” Further, we find that after SEC comments on the industry leader's disclosure, No‐letter Firms also provide more firm‐specific disclosures in the subsequent year. The increased disclosure specificity reduces these firms’ likelihood of receiving SEC risk disclosure comments on their new filings. Our evidence suggests an indirect effect of the SEC review of qualitative disclosure.  相似文献

The concept of food regimes, as developed by Friedmann and McMichael, has proven useful in analysing how systems of food production, distribution, and consumption are linked to cycles of global capital accumulation and identifying the contradictions and conflicts that underlie them. A question that food regime analysis is relatively less able to address, however, is how food regimes become established and endure with the apparent acquiescence of those who are the victims of their contradictions and inequities. In this paper, I argue that a deeper engagement with Gramsci's theory of hegemony may help to address this lacuna in food regime analysis. To illustrate my case, I draw on studies of rural India from the colonial period to the present day, highlighting the ways in which the hegemonic mechanisms of consent and coercion have been crucial to the consolidation of each of the three food regimes identified by Friedmann and McMichael.  相似文献
