Care for uterine fibroids: another casualty of the COVID pandemic
No full textInternational audienceOverall, during the COVID-19 pandemic, a large proportion of uterine fibroids were not managed in the hospital setting. The lockdown period was associated with large reductions in hospital service utilisation, particularly for non-emergency patients. As we observed no shortterm post-lockdown catch-up, two questions arise: What became of these untreated patients? How has their future health been affected? Two hypotheses appear likely. The first is that the woman continued receiving outpatient care, but the therapeutic procedures took place only in hospitals and there were fewer of them. While medical treatment could theoretically have been used, the only available treatment was removed from the market in March 2020 due to the risk of serious drug-induced hepatitis. The second is that of non-recourse to care, or its deferral for more than a year, or even therapeutic abstention because no kind of treatment was available. This strongly suggests a loss of opportunity for these women, with its accompanying risks of hysterectomy, of transfusions, and of impaired quality of life
Nursing homes and mortality in Europe: Uncertain causality
No full textInternational audienceThe current health crisis has particularly affected the elderly population. Nursing homes have unfortunately experienced a relatively large number of deaths. On the basis of this observation and working with European data (from SHARE), we want to check whether nursing homes were lending themselves to excess mortality even before the pandemic. Controlling for a number of important characteristics of the elderly population in and outside nursing homes, we conjecture that the difference in mortality between those two samples is to be attributed to the way nursing homes are designed and organized. Using matching methods, we observe excess mortality in Sweden, Belgium, Germany, Switzerland, Czech Republic and Estonia but not in the Netherlands, Denmark, Austria, France, Luxembourg, Italy and Spain. This raises the question of the organization and management of these nursing homes, but also of their design and financing
Environment, public debt and epidemics
No full textInternational audienceWe study whether fiscal policies, especially public debt, can help to curb the macroeconomic and health consequences of epidemics. Our approach is based on three main features: we introduce the dynamics of epidemics in an overlapping generations model to take into account that old people are more vulnerable; people are more easily infected when pollution is high; public spending in health care and public debt can be used to tackle the effects of epidemics. We show that fiscal policies can promote convergence to a stable disease-free steady state. When public policies are not able to permanently eradicate the epidemic, public debt, and income transfers could reduce the number of infected people and increase capital and GDP per capita. As a prerequisite, pollution intensity should not be too high. Finally, we define a household subsidy policy that eliminates income and welfare inequalities between healthy and infected individuals
Fiscal Incentives for Conflict: Evidence from India's Red Corridor
No full textInternational audienceCan tax regimes shape the incentives to engage in armed conflict? Indian mining royalties benefit the States, but are set by the central government. India's Maoist belt is mineral-rich, and States are responsible for counterinsurgency operations. We exploit the introduction of a 10% ad valorem tax on iron ore that increased royalty collections of the affected states by a factor of 10. We find that the royalty hike was followed by a significant intensification of violence in districts with important iron ore deposits. The royalty increase was also followed by an increase in illegal mining activity in iron mines
Value and Money as Social Power: New Concepts for Old Questions
No full textEarly Access JUN 2022International audienceThe individualistic methodology that largely dominates economic thought is incapable of thinking of social facts as anything other than the aggregation of individual facts. In so doing, it ignores the powerful sui generis forces that emanate from the social sphere itself and that shape individual behaviour and subjectivity. Moral, aesthetic, and religious values are the paradigmatic illustration of this. But economic value is also a force of this nature. It cannot be identified with a substance, be it utility or labour. This new perspective provides the economist with new tools for thinking about what a monetary community is. In so doing, it lays the foundations for a renewed dialogue with the social sciences in general and sociology in particular
Existence of an equilibrium in arrowian markets for consumption externalities
No full textInternational audienceWe study the existence of quasi-equilibria and equilibria for pure exchange economies with consumption externalities and Arrowian markets with personalized Lindahl prices. We provide examples showing first that quasi-equilibria and equilibria of the externality economy fail to exist under assumptions guaranteeing existence for economies without externalities. We show that the externality economy has identical equilibrium allocations of an appropriately defined constant returns to scale production economy without externalities. We exploit this equivalence to map sufficient conditions for the existence of quasi-equilibria and equilibria of the production economy into sufficient conditions of the pure exchange economy with externalities, thereby unveiling suitable irreducibility conditions and survival conditions
The Quran and the Sword
No full textInternational audienceThis paper elucidates the willingness of an autocrat to push through institutional reforms in a context where traditional authorities represented by religious clerics are averse to them and where the military control the means of repression and can potentially stage a coup. We show that although the autocrat always wants to co-opt the military, this is not necessarily true of the clerics. Exclusive co-option of the military obtains where the loyalty of the autocrat’s army is strong while the organizational strength of religious movements is rather low. Radical institutional reforms can then be implemented. Empirically, the dominant regime in contemporary Muslim countries is the regime of double co-option where the autocrat resorts to a double-edged tactic: pleasing the official clerics by slowing the pace of reforms and ensuring the loyalty of the military so as to put down clerics-led rebellions

How to Balance Lives and Livelihoods in a Pandemic
No full textInternational audienceThe COVID-19 crisis and the policy responses to it have impacted many different areas of common concern including public health and the economy. This raises difficult questions about how to balance these concerns in making policy decisions. In this chapter, we review a number of tools that welfare economics offers for conceptualizing and studying such trade-offs. We argue that social welfare analysis is the most useful method for doing so. We show how concerns for the distributive and other effects of a policy on individual wellbeing can be evaluated using a Social Welfare Function (SWF) and survey some of the main features of such functions. As an illustration, we then use this approach to model and evaluate the implications for social welfare of the adoption of pandemic policies that vary in terms of the stringency of the controls that they impose on individual behaviour. Our model reveals how such evaluations not only are determined by empirical facts but may also depend on key judgments about the relative importance of the different determinants of individual wellbeing (health, income, longevity, and so on) and about the extent to which special concern should be given to the worse-off. In doing so, it illustrates how critical transparent modelling of these concerns is in developing responses to pandemics of this kind
Optimal coalition splitting with heterogenous strategies
No full textInternational audiencePurpose – The authors characterize the conditions under which a country may eventually split and when it splits within an infinite horizon multi-stage differential game.Design/methodology/approach – In contrast to the existing literature, the authors do not assume that after splitting, players will adopt Markovian strategies. Instead, the authors assume that while the splitting country plays Markovian, the remaining coalition remains committed to the collective control of pollution and plays open-loop.Findings – Within a full linear-quadratic model, the authors characterize the optimal strategies. The authors later compare with the outcomes of the case where the splitting country and the remaining coalition play both Markovian. The authors highlight several interesting results in terms of the implications for long-term pollution levels and the duration of coalitions under heterogenous strategies as compared to Markovian behavior.Originality/value – In this paper, the authors have illustrated the richness of the simplications of enlarging the set of strategies in terms of the emergence of coalitions, their duration and the implied welfare levels per player. Varying only three parameters (the technological gap, pollution damage and coalition payoff share distribution across players), the authors have been able to generate, among other findings, quite different rankings of welfare per player depending on whether the remaining coalitions after split play Markovian or stay precommited to the pre-splitting period decision
