A BLESSING OR A CURSE? BEING A UNICORN FIRM IN THE IPO MARKET
신서원,박의성,Suresh Kotha 한국경영학회 2021 한국경영학회 통합학술발표논문집 Vol.2021 No.8
By examining a novel entrepreneurial phenomenon-the emergence of unicorn ventures-we investigate the discrepancies between theoretical assertions and empirical evidence in the initial public offering (IPO) underpricing of such ventures. Unicorn ventures are private new ventures valued at over $1 billion. Drawing on the “sociology of expectations” literature, we suggest that at IPO, unicorn ventures experience a greater level of IPO underpricing relative to other firms because of media uncertainty stemming from the high expectations surrounding the venture’s future performance. We tested our hypotheses using a unique hand-collected dataset that includes the entire population of unicorn IPOs between 2011 and 2018. We found that the media coverage (both the volume and tenor of such content) does not explain unicorn ventures’ significantly greater IPO underpricing relative to other ventures. However, the sentiment polarity of unicorn ventures in the media was positively associated with IPO underpricing. Also, pre-IPO profitability, and a legitimacy jolt experienced at a point in the study, moderated the relationship between sentimental polarity and IPO underpricing. We demonstrate how the sociology of expectations literature can provide a sound theoretical lens to explain the persistence of IPO underpricing beyond past explanations of this important phenomenon.

Background Incisional hernia is a common complication following visceral organ transplantation. Transplant patients are at increased risk of primary and recurrent hernias due to chronic immune suppression and large incisions. We conducted a retrospective review of patients with a history of liver or kidney transplantation who underwent hernia repair to analyze outcomes and hernia recurrence. Methods This is a single center, retrospective review of 19 patients who received kidney and/or liver transplantation prior to presenting with an incisional hernia from 2011 to 2017. All hernias were repaired with open component separation technique (CST) with biologic mesh underlay. Results The mean age of patients was 61.0±8.3 years old, with a mean body mass index of 28.4±4.8 kg/m2, 15 males (78.9%), and four females (21.1%). There were seven kidney, 11 liver, and one combined liver and kidney transplant patients. The most common comorbidities were hypertension (16 patients, 84.2%), diabetes (9 patients, 47.4%), and tobacco use (8 patients, 42.1%). Complications occurred in six patients (31.6%) including hematoma (1/19), abscess (1/19), seroma (2/19), and hernia recurrence (3/19) at mean follow-up of 28.7±22.8 months. With the exception of two patients with incomplete follow-up, all patients healed at a median time of 27 days. Conclusions This small, retrospective series of complex open CST in transplant patients shows acceptable rates of long-term hernia recurrence and healing. By using a multidisciplinary approach for abdominal wall reconstruction, we believe that modified open CST with biologic mesh is a safe and effective technique in the transplant population with complex abdominal hernias.
