Recent work has emphasized the benefits of patient–physician concordance on clinical care outcomes for underrepresented minorities, arguing it can ameliorate outgroup biases, boost communication, and increase trust. We explore concordance in a setting where racial disparities are particularly severe: childbirth. In the United States, Black newborns die at three times the rate of White newborns. Results examining 1.8 million hospital births in the state of Florida between 1992 and 2015 suggest that newborn–physician racial concordance is associated with a significant improvement in mortality for Black infants. Results further suggest that these benefits manifest during more challenging births and in hospitals that deliver more Black babies. We find no significant improvement in maternal mortality when birthing mothers share race with their physician.

We examine patient gender disparities in survival rates following acute myocardial infarctions (i.e., heart attacks) based on the gender of the treating physician. Using a census of heart attack patients admitted to Florida hospitals between 1991 and 2010, we find higher mortality among female patients who are treated by male physicians. Male patients and female patients experience similar outcomes when treated by female physicians, suggesting that unique challenges arise when male physicians treat female patients. We further find that male physicians with more exposure to female patients and female physicians have more success treating female patients.

Male entrepreneurs are known to raise higher levels of funding than their female counterparts, but the underlying mechanism for this funding disparity remains contested. Drawing upon Regulatory Focus Theory, we propose that the gap originates with a gender bias in the questions that investors pose to entrepreneurs. A field study conducted on question and answer interactions at TechCrunch Disrupt New York City during 2010 through 2016 reveals that investors tend to ask male entrepreneurs promotion-focused questions and female entrepreneurs prevention-focused questions, and that entrepreneurs tend to respond with matching regulatory focus. This distinction in the regulatory focus of investor questions and entrepreneur responses results in divergent funding outcomes for entrepreneurs whereby those asked promotion-focused questions raise significantly higher amounts of funding than those asked prevention-focused questions. We demonstrate that every additional prevention-focused question significantly hinders the entrepreneur's ability to raise capital, fully mediating gender's effect on funding. By experimentally testing an intervention, we find that entrepreneurs can significantly increase funding for their startups when responding to prevention-focused questions with promotion-focused answers. As we offer evidence regarding tactics that can be employed to diminish the gender disadvantage in funding outcomes, this study has practical as well as theoretical implications for entrepreneurship.

Entrepreneurship is a central path to job creation, economic growth, and prosperity. In the earliest stages of start-up business creation, the matching of entrepreneurial ventures to investors is critically important. The entrepreneur's business proposition and previous experience are regarded as the main criteria for investment decisions. Our research, however, documents other critical criteria that investors use to make these decisions: the gender and physical attractiveness of the entrepreneurs themselves. Across a field setting (three entrepreneurial pitch competitions in the United States) and two experiments, we identify a profound and consistent gender gap in entrepreneur persuasiveness. Investors prefer pitches presented by male entrepreneurs compared with pitches made by female entrepreneurs, even when the content of the pitch is the same. This effect is moderated by male physical attractiveness: attractive males were particularly persuasive, whereas physical attractiveness did not matter among female entrepreneurs.physical appearance | persuasion

We develop a theoretical model, grounded in exchange theory, about the process through which relationships between entrepreneurs and investors develop and influence the growth of new ventures. Our theory highlights the multifaceted relationships that entrepreneurs and investors share-comprising both affective and instrumental dimensions-and the bidirectional exchanges of social and financial resources that build these relationships over time. An exchange theory perspective sheds light on the emergence of different patterns of relationship development over time and how different kinds of resource exchange contribute to new venture growth, contingent on the core problems that a venture faces at a given stage of development. We discuss implications of an exchange perspective on resources and relationships in entrepreneurship for theory, research, and practice.

Diabetes mellitus complicates pregnancies, leading to diseases in adult life in the offspring. Asymmetric dimethylarginine (ADMA) is increased in diabetes mellitus, kidney disease, and hypertension. We tested whether maternal diabetes causes increased ADMA in rats, resulting in kidney disease and hypertension in the adult offspring, and whether these can be prevented by maternal citrulline supplementation. Newborn female and pregnant Sprague-Dawley rats were injected with streptozotocin (STZ), which made up the nSTZ and STZ models, respectively. For the STZ model, 4 groups of male offspring were killed at age 3 months: the control, STZ, and Cit and STZ+Cit (control and STZ rats treated with 0.25% l-citrulline solution, respectively) groups. The nSTZ rats had lower nephron numbers. The renal level of ADMA was higher in the nSTZ rats than in controls. The STZ group developed kidney injury, renal hypertrophy, and elevated blood pressure at the age of 12 weeks. These conditions were found to be associated with increased ADMA levels, decreased nitric oxide (NO) production, and decreased dimethylarginine dimethylaminohydrolase (DDAH) activity in the kidney. In addition, ADMA caused a nephron deficit in cultured rat metanephroi. Maternal citrulline supplementation prevented hypertension and kidney injury, increased the renal DDAH-2 protein level, and restored the levels of ADMA and NO in the STZ+Cit group. Reduced nephron number and increased ADMA contribute to adult kidney disease and hypertension in offspring of mothers with STZ-induced diabetes. Manipulation of the ADMA-NO pathway by citrulline supplementation may be a potential approach to prevent these conditions.

Recent studies find that female-led ventures are penalized relative to male-led ventures as a result of role incongruity or a perceived “lack of fit” between female stereotypes and expected personal qualities of business entrepreneurs. We examine whether social impact framing that emphasizes a venture’s social–environmental welfare benefits, which research has shown to elicit stereotypically feminine attributions of warmth, diminishes these penalties. We initially investigate this proposition in a field study of evaluations of early-stage ventures and find evidence of lessened gender penalties for female-led ventures that are presented using a social impact frame. In a second study, we experimentally validate this effect and show that it is mediated by the effect of social impact framing on perceptions of the entrepreneur’s warmth. The effect of social impact frames on venture evaluations did not apply to men, was not a result of perceptions of increased competence, and was not conditional on the gender of evaluators. Taken together, our findings demonstrate that social impact framing increases attributions of warmth for all entrepreneurs but with positive consequences on business evaluation only for female-led ventures, for which increased perceptions of warmth attenuate female entrepreneurs’ gender role incongruity.
