Development as Freedom

Summary Background Since December, 2019, Wuhan, China, has experienced an outbreak of coronavirus disease 2019 (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Epidemiological and clinical characteristics of patients with COVID-19 have been reported but risk factors for mortality and a detailed clinical course of illness, including viral shedding, have not been well described. Methods In this retrospective, multicentre cohort study, we included all adult inpatients (≥18 years old) with laboratory-confirmed COVID-19 from Jinyintan Hospital and Wuhan Pulmonary Hospital (Wuhan, China) who had been discharged or had died by Jan 31, 2020. Demographic, clinical, treatment, and laboratory data, including serial samples for viral RNA detection, were extracted from electronic medical records and compared between survivors and non-survivors. We used univariable and multivariable logistic regression methods to explore the risk factors associated with in-hospital death. Findings 191 patients (135 from Jinyintan Hospital and 56 from Wuhan Pulmonary Hospital) were included in this study, of whom 137 were discharged and 54 died in hospital. 91 (48%) patients had a comorbidity, with hypertension being the most common (58 [30%] patients), followed by diabetes (36 [19%] patients) and coronary heart disease (15 [8%] patients). Multivariable regression showed increasing odds of in-hospital death associated with older age (odds ratio 1·10, 95% CI 1·03–1·17, per year increase; p=0·0043), higher Sequential Organ Failure Assessment (SOFA) score (5·65, 2·61–12·23; p Interpretation The potential risk factors of older age, high SOFA score, and d-dimer greater than 1 μg/mL could help clinicians to identify patients with poor prognosis at an early stage. Prolonged viral shedding provides the rationale for a strategy of isolation of infected patients and optimal antiviral interventions in the future.

Clinical course and risk factors for mortality of adult inpatients with COVID-19 in Wuhan, China: a retrospective cohort study

Food’s environmental impacts are created by millions of diverse producers. To identify solutions that are effective under this heterogeneity, we consolidated data covering five environmental indicators; 38,700 farms; and 1600 processors, packaging types, and retailers. Impact can vary 50-fold among producers of the same product, creating substantial mitigation opportunities. However, mitigation is complicated by trade-offs, multiple ways for producers to achieve low impacts, and interactions throughout the supply chain. Producers have limits on how far they can reduce impacts. Most strikingly, impacts of the lowest-impact animal products typically exceed those of vegetable substitutes, providing new evidence for the importance of dietary change. Cumulatively, our findings support an approach where producers monitor their own impacts, flexibly meet environmental targets by choosing from multiple practices, and communicate their impacts to consumers.

Utility Analysis and the Consumption Function: An Interpretation of Cross-Section Data

The scope of this paper is to celebrate the 100th anniversary of the Gini index by providing the original formulae. Corrado Gini introduced his index for the first time in a 1912 book published in Italian under the name of “Variabilita e Mutabilita” (Variability and Mutability). This article provides selected extracts of Part I of the book dedicated to measures of variability. We find that Gini proposed no less than 13 formulations of his index, none of which is known today to the large public. We also find that Gini anticipated some of the developments that derived from the study of his index.

Does freedom of choice have an intrinsic value for people and how do people value freedom of choice? Drawing on economics and social psychology the paper provides a theory and empirical evidence of how individuals may value freedom of choice and derive utility from it. It is argued that the degree of control that we think we have over choice regulates how we value freedom of choice and that each individual faces a freedom `threshold' beyond which more freedom turns into disutility. We find strong evidence in support of this hypothesis. Making use of a combination of all rounds of the World and European Values Surveys we find a variable that measures freedom and control to be the best predictor of life satisfaction worldwide. This variable predicts life satisfaction better than any other known factors such as employment, income or marriage in every country and across countries. A test shows that this variable is not a proxy of life satisfaction and that measures well both freedom and control. The implications of this finding for economics range from utility and choice theory to public policies.

Happiness, Freedom and Control

How do people value freedom of choice ? Drawing on economics and psychology the paper provides an hypothesis and empirical evidence on how individuals may value freedom of choice and derive utility from it. It is argued that the degree of perceived control that individuals have over choice – a construct known as the locus of control in psychology – regulates how we value freedom of choice. People who believe that the outcome of their actions depends on internal factors such as effort and skills (the ‘internals’) have a greater appreciation of freedom of choice than people who believe that the outcome of their actions depends on external factors such as fate or destiny (the ‘externals’). We find some evidence in support of this hypothesis using a combination of all rounds of the World and European Values Surveys. A variable that measures freedom of choice and the locus of control is found to predict life satisfaction better than any other known factor such as health, employment, income, marriage or religion, across countries and within countries. We show that this variable is not a proxy of happiness and measures well both freedom of choice and the locus of control. ‘Internals’ are found to appreciate freedom of choice more than ‘externals’ and to be happier. These findings have important implications for individual utility, social welfare and public policies.

Do people care about income inequality and does income inequality affect subjective well-being? Welfare theories can predict either a positive or a negative impact of income inequality on subjective well-being and empirical research has found evidence of a positive, negative, or non-significant relation. This paper attempts to determine some of the possible causes of such empirical heterogeneity. Using a very large sample of world citizens we test the consistency of the effect of income inequality in predicting life satisfaction. We find that income inequality has a negative and significant effect on life satisfaction. This result is robust to changes of regressors and estimation choices and also persists across different income groups and across different types of countries. However, this relation is easily obscured or reversed by multicollinearity generated by the use of country and year fixed effects. This is particularly true if the number of data points for inequality is small, which is a common feature of cross-country or longitudinal studies.
