Using firm-level data from an EBRD/EIB/WB joint survey covering more than 6,000 private firms in eight countries in the Middle East and North Africa, this paper (i) examines the relationship between firm characteristics and their perception of the effect of political instability on their operations and (ii) tests whether political instability has had a negative effect on firm performance. Using ordered and binary probit/logit models, we find that (i) export-oriented and larger-sized firms are more likely to report political instability as a sever obstacle to their operations. Using OLS and an endogenous treatment linear regression models, we find that (ii) the perception of political instability is negatively

Background Anemia can negatively affect the outcome of many diseases, including infections and inflammatory conditions. Aim To compare the prognostic value of hemoglobin level and the neutrophil/lymphocyte ratio (NLR) for prediction of coronavirus disease 2019 (COVID-19) severity. Methods In this retrospective cohort study, clinical data from patients with laboratory-confirmed COVID-19 were collected from hospital records from 10 April 2020 to 30 July 2020. Results The proportions of patients with mild, moderate, and severe COVID-19 differed significantly in association with hemoglobin levels, neutrophil counts, lymphocyte counts, NLR, and total leukocyte counts. Patients with severe COVID-19 had significantly lower hemoglobin levels than those with moderate or mild COVID-19. There were statistically significant negative associations between hemoglobin and D-dimer, age, and creatinine. The optimal hemoglobin cut-off value for prediction of disease severity was 11.6 g/dL. Using this cut-off value, hemoglobin had higher negative predictive value and sensitivity than NLR (92.4% and 51.3%, respectively). The specificity of hemoglobin as a prognostic marker was 79.3%. Conclusion Both NLR and hemoglobin level are of prognostic value for predicting severity of COVID-19. However, hemoglobin level displayed higher sensitivity than NLR. Hemoglobin level should be assessed upon admission in all patients and closely monitored throughout the disease course.

This paper finds empirical evidence that faster and smarter containment measures were associated with lower fiscal responses to the COVID-19 shock. We also find that initial conditions, such as fiscal space, income, health preparedness and budget transparency were important in shaping the amount and design of the COVID-19 fiscal response.
