• Economic Uncertainty Before and During the COVID-19 Pandemic. Journal of public economics Altig, D., Baker, S., Barrero, J. M., Bloom, N., Bunn, P., Chen, S., Davis, S. J., Leather, J., Meyer, B., Mihaylov, E., Mizen, P., Parker, N., Renault, T., Smietanka, P., Thwaites, G. 2020: 104274

  Abstract

  We consider several economic uncertainty indicators for the US and UK before and during the COVID-19 pandemic: implied stock market volatility, newspaper-based policy uncertainty, twitter chatter about economic uncertainty, subjective uncertainty about business growth, forecaster disagreement about future GDP growth, and a model-based measure of macro uncertainty. Four results emerge. First, all indicators show huge uncertainty jumps in reaction to the pandemic and its economic fallout. Indeed, most indicators reach their highest values on record. Second, peak amplitudes differ greatly - from a 35% rise for the model-based measure of US economic uncertainty (relative to January 2020) to a 20-fold rise in forecaster disagreement about UK growth. Third, time paths also differ: Implied volatility rose rapidly from late February, peaked in mid-March, and fell back by late March as stock prices began to recover. In contrast, broader measures of uncertainty peaked later and then plateaued, as job losses mounted, highlighting differences between Wall Street and Main Street uncertainty measures. Fourth, in Cholesky-identified VAR models fit to monthly U.S. data, a COVID-size uncertainty shock foreshadows peak drops in industrial production of 12-19%.

• Hospital Board And Management Practices Are Strongly Related To Hospital Performance On Clinical Quality Metrics HEALTH AFFAIRS Tsai, T. C., Jha, A. K., Gawande, A. A., Huckman, R. S., Bloom, N., Sadun, R. 2015; 34 (8): 1304-1311

  Abstract

  National policies to improve health care quality have largely focused on clinical provider outcomes and, more recently, payment reform. Yet the association between hospital leadership and quality, although crucial to driving quality improvement, has not been explored in depth. We collected data from surveys of nationally representative groups of hospitals in the United States and England to examine the relationships among hospital boards, management practices of front-line managers, and the quality of care delivered. First, we found that hospitals with more effective management practices provided higher-quality care. Second, higher-rated hospital boards had superior performance by hospital management staff. Finally, we identified two signatures of high-performing hospital boards and management practice. Hospitals with boards that paid greater attention to clinical quality had management that better monitored quality performance. Similarly, we found that hospitals with boards that used clinical quality metrics more effectively had higher performance by hospital management staff on target setting and operations. These findings help increase understanding of the dynamics among boards, front-line management, and quality of care and could provide new targets for improving care delivery.

  Abstract

  To improve the quality of health care, many researchers have suggested that health care institutions adopt management approaches that have been successful in the manufacturing and technology sectors. However, relatively little information exists about how these practices are disseminated in hospitals and whether they are associated with better performance.To describe the variation in management practices among a large sample of hospital cardiac care units; assess association of these practices with processes of care, readmissions, and mortality for patients with acute myocardial infarction (AMI); and suggest specific directions for the testing and dissemination of health care management approaches.We adapted an approach used to measure management and organizational practices in manufacturing to collect management data on cardiac units. We scored performance in 18 practices using the following 4 dimensions: standardizing care, tracking of key performance indicators, setting targets, and incentivizing employees. We used multivariate analyses to assess the relationship of management practices with process-of-care measures, 30-day risk-adjusted mortality, and 30-day readmissions for acute myocardial infarction (AMI).Cardiac units in US hospitals.Five hundred ninety-seven cardiac units, representing 51.5% of hospitals with interventional cardiac catheterization laboratories and at least 25 annual AMI discharges.Process-of-care measures, 30-day risk-adjusted mortality, and 30-day readmissions for AMI.We found a wide distribution in management practices, with fewer than 20% of hospitals scoring a 4 or a 5 (best practice) on more than 9 measures. In multivariate analyses, management practices were significantly correlated with mortality (P = .01) and 6 of 6 process measures (P < .05). No statistically significant association was found between management and 30-day readmissions.The use of management practices adopted from manufacturing sectors is associated with higher process-of-care measures and lower 30-day AMI mortality. Given the wide differences in management practices across hospitals, dissemination of these practices may be beneficial in achieving high-quality outcomes.

  Abstract

  HBR's 90th anniversary is a sensible time to revisit a basic question: Are organizations more likely to succeed if they adopt good management practices? The answer may seem obvious to most HBR readers, but these three economists cast their net much wider than that. In a decadelong study of thousands of organizations in 20 countries, they and their interview teams assessed how well manufacturers, schools, and hospitals adhere to three management basics: targets, incentives, and monitoring. They found that huge numbers of companies follow none of those fundamentals, that adopting the basics yields big improvements in outcomes such as productivity and longevity, and that good nuts-and-bolts management at individual firms shapes national performance. At 14 textile manufacturers in India, for example, an intervention--involving free, high-quality advice from a consultant who was on-site half-time for five months--cut defects by half, reduced inventory by 20%, and raised output by 10%. A control group saw no such gains. The authors' global data set suggests that implementing good management at schools and hospitals yields change more slowly than at manufacturers--but it does come eventually. And the macroeconomic potential--for incomes, productivity, and delivery of critically needed services--is huge. A call for "better management" may sound prosaic, but given the global payoffs, it's actually quite radical.
