Abstract:

Based on a longitudinal, qualitative analysis of developments in the English National Health Service, we develop a process model of how organizations divest or spin off units with the aim of establishing two or more autonomous organizational entities while simultaneously managing their continued interdependencies. We find that effective organizational separation depends on generating two types of respect鈥攁ppraisal and recognition respect鈥攂etween the divesting and divested units. Appraisal respect involves showing appreciation for competence or the effort to achieve it, while recognition respect requires considering what someone cares about鈥攕uch as values or concerns鈥攁nd acknowledging that they matter. The process model we develop shows that open communication is crucial to the development of both. We also find that certain attempts to gain organizational independence and respect may unintentionally undermine the development of autonomy. Counterintuitively, we find that increasing or maintaining interorganizational links via communication may facilitate organizational separation, while attempts by units to distance themselves from one another may unintentionally inhibit it. By linking organizational separation, autonomy, independence, and respect, this paper develops theory on organizational separation processes and more generally enhances our understanding of organizational autonomy and its relations with mutual respect.

Abstract:

We quantify the pervasiveness of informed trading activity in target companies' equity options before the announcements of 1,859 U.S. takeovers between 1996 and 2012. About 25% of all takeovers have positive abnormal volumes, which are greater for short-dated out-of-the-money calls, consistent with bullish directional trading before the announcement. Over half of this abnormal activity is unlikely due to speculation, news and rumors, trading by corporate insiders, leakage in the stock market, deal predictability, or beneficial ownership filings by activist investors. We also examine the characteristics of option trades litigated by the SEC for alleged illegal insider trading. While the characteristics of such trades closely resemble the patterns of abnormal option volume in the U.S. takeover sample, we find that the SEC litigates only about 8% of all deals in it.

Abstract:

Recent studies show that the standard test portfolios do not contain sufficient information to discriminate between asset pricing models. To address this issue, we develop a large-scale approach that expands the cross-section to several thousand portfolios. Our novel approach is simple, widely applicable, and allows for formal evaluation/comparison tests. Its benefits are confirmed in empirical tests of CAPM- and characteristic-based models. While these models are all misspecified, we uncover striking performance differences between them. In particular, the human capital and conditional CAPMs largely outperform the CAPM which suggests that labor income and time-varying recession risks are primary concerns for investors.
