[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 presents an in-depth longitudinal case study examining the processes through which practitioners in two Big 4 professional services firms have attempted to construct sustainability assurance (independent assurance on sustainability reports). Power’s (1996, 1997, 1999, 2003) theorization of the way in which new subject areas are made auditable is used to frame the findings. The case analysis reveals the fragile nature of efforts to innovate with sustainability assurance and render sustainability reporting auditable. It suggests that innovation in new assurance practices may be constrained by an over-reliance on traditional financial audit training and techniques and certain internal professional services firm control procedures. Practitioners are shown to have experienced considerable discomfort in their attempts to construct a stable and legitimate knowledge base for assurance practice. Tacit knowledge embedded in highly subjective assessments of evidence has been frequently enrolled to make assurance possible in the presence of vague guidance from assurance standards. In light of ongoing practitioner struggles, both firms have publicly acknowledged the limitations of traditional financial audit practice operating alone in the conduct of sustainability assurance. In order to offset these limitations, they have proposed a coupling of ‘‘expert’’ stakeholder assessments of reporting completeness with traditional audit assessments of data reliability. This assigns part of the responsibility for delivering on a key assurance objective (reporting completeness) to what many practitioners perceive as questionable stakeholder expertise. The findings extend prior research highlighting the trial and error nature of the processes through which accountants seek to develop their presence in new markets for their expertise. They also question the extent to which the core aims being espoused for sustainability assurance can be substantively aligned with the operational capabilities available within Big 4 professional services firms

Most studies of comparative productivities fail to find evidence of convergence in OECD manufacturing despite major economic growth theories predicting convergence. Using manufacturing data for nineteen OECD countries over the period from 1870 to 2006, this study finds strong evidence of unconditional β-convergence as well as σ-convergence. Panel data estimates suggest that the convergence has been driven by domestic R&D, international R&D spillovers, and financial development as predicted by Schumpeterian growth theories.

This study shows the influence of investor sentiment on the market's mean–variance tradeoff. We find that the stock market's expected excess return is positively related to the market's conditional variance in low-sentiment periods but unrelated to variance in high-sentiment periods. These findings are consistent with sentiment traders who, during the high-sentiment periods, undermine an otherwise positive mean–variance tradeoff. We also find that the negative correlation between returns and contemporaneous volatility innovations is much stronger in the low-sentiment periods. The latter result is consistent with the stronger positive ex ante relation during such periods

We present a simple model that rationalizes performance persistence in hedge fund limited partnerships. In contrast to the model for mutual funds of Berk and Green (2004), the learning in our model pertains to profitability associated with an innovative trading strategy or emerging sector, rather than ability specific to the fund manager. As a result of potential information spillovers, which would increase competition if informed investors were to partner with non-incumbent managers, incumbent managers will let informed investors benefit from increases in estimated profitability following high returns realized with the trading strategy or in the sector

[Academics responded to the challenges posed by the 2008 financial crisis with a flurry of studies. This collection of articles is just the academic community's first look into it. The articles begin with an examination at the last national housing price crash: the great depression of the 1930s. This is followed by articles looking at the current mortgage market and how it behaved. Did modern innovations reflect or add to the downturn? The next set of papers examines how non-financial firms were impacted by the crash. To what degree did credit worthy firms nevertheless find themselves without access to capital? The papers then end with a look into how the banking sector itself fared throughout this period

We propose a formal test of the hypothesis that energy prices are predetermined with respect to U.S. macroeconomic aggregates. The test is based on regressing changes in daily energy prices on daily news from U.S. macroeconomic data releases. Using a wide range of macroeconomic news, we find no compelling evidence of feedback at daily or monthly horizons, contradicting the view that energy prices respond instantaneously to macroeconomic news and consistent with the commonly used identifying assumption that there is no feedback from U.S. macroeconomic aggregates to monthly innovations in energy prices
