It is not directly observable how effectively a society practices social distancing during the COVID-19 pandemic. This paper proposes a novel and robust methodology to identify latent social distancing at the country level. We extend the Susceptible-Exposed-Infectious-Recovered-Deceased (SEIRD) model with a time-varying, country-specific distancing term, and derive the Model-Inferred DIStancing index (MIDIS) for 120 countries using readily available epidemiological data. The index is not sensitive to measurement errors in epidemiological data and to the values assigned to model parameters. The evolution of MIDIS shows that countries exhibit diverse patterns of distancing during the first wave of the COVID-19 pandemic—a persistent increase, a trendless fluctuation, and an inverted U are among these patterns. We then implement regression analyses using MIDIS and obtain the following results: First, MIDIS is strongly correlated with available mobility statistics, at least for high income countries. Second, MIDIS is also strongly associated with (i) the stringency of lockdown measures (governmental response), (ii) the cumulative number of deceased persons (behavioral response), and (iii) the time that passed since the first confirmed case (temporal response). Third, there is statistically significant regional variation in MIDIS, and more developed societies achieve higher distancing levels. Finally, MIDIS is used to explain output losses experienced during the pandemic, and it is shown that there is a robust positive relationship between the two, with sizable economic effects.  相似文献

Abstract.  This paper studies the links between macroeconomic adjustment and poverty. The first part summarizes some of the recent evidence on poverty in the developing world. The second reviews the various channels through which macroeconomic policies affect the poor, whereas the third is devoted to the specific role of the labor market. It presents an analytical framework that captures some of the main features of the urban labor market in developing countries and studies the effects of fiscal adjustment on wages, employment, and poverty. The fourth part presents cross‐country regressions linking various macroeconomic and structural variables to poverty. Higher levels and growth rates of per capita income, higher rates of real exchange rate depreciation, better health conditions, and a greater degree of commercial openness lower poverty, whereas inflation, greater income inequality, and macroeconomic volatility tend to increase it. Moreover, the impact of growth on poverty appears to be asymmetric; it seems to result from a significant relationship between episodes of increasing poverty and negative growth rates.  相似文献

Abstract Equality of opportunity is a widely accepted principle of distributive justice and it is the leading idea of most political platforms in several countries. According to this principle, a society might institute policies that secure an equal distribution of the means to reach a valuable outcome among its members. Once the set of opportunities have been equalized, which particular opportunity, the individual chooses from those open to her, is outside the scope of justice. Ex ante inequalities, and only those inequalities, should be eliminated or compensated for by public intervention. The recent literature on the opportunity egalitarianism often merges these questions introducing two different economic issues. On one side the design of a public policy intended to implement the equality of opportunity view and on the other side the problem of measuring the degree of opportunity inequality in a society. We describe the basic setting and assumptions of some different approaches derived by Roemer’s algorithm for public policy and then we discuss some theoretical and empirical studies to separate and test alternative paradigms on the measurement of inequality of opportunity. Accordingly, an extended critique on the causality issue on policies and measurements is taken into account.  相似文献

英国住房保障政策的体系、进展与反思   总被引:2,自引:0,他引:2  
英国是世界上最早实施政府干预住房市场的国家,早在1919年颁布的《住房和城镇规划法》中就明确规定居民住房问题为公共事务,政府对此负有义务。经过不断的摸索和改进,英国的住房保障政策从起初的政府直接供给公共住房,逐渐向政府以财政、金融等手段鼓励扶持社会化公共住房的建造与运营转变。本文对英国20世纪90年代以来的住房保障体系演变与发展现状做了介绍,并重点对扶持政策、资助项目、主管机构、融资方式等方面进行了详细阐述,以期对今后我国住房保障相关政策的研究制定有所启示。  相似文献

This article studies the optimal intertemporal allocation of resources devoted to the prevention of deterministic infectious diseases that admit an endemic steady-state. Under general assumptions, the optimal control problem is shown to be formally similar to an optimal growth model with endogenous discounting. The optimal dynamics then depends on the interplay between the epidemiological characteristics of the disease, the labor productivity and the degree of intergenerational equity. Phase diagrams analysis reveals that multiple trajectories, which converge to endemic steady-states with or without prevention or to the elimination of the disease, are feasible. Elimination implies initially a larger prevention than in other trajectories, but after a finite date, prevention is equal to zero. This “sooner-the-better” strategy is shown to be optimal if the pure discount rate is sufficiently low.  相似文献

Public and private hospitals are seen to co-exist in several countries and they have different levels of service, waiting times and prices. Public hospitals, in general, are cheaper, but more crowded and offer lower quality service than private ones while private ones are underutilized because of the higher payments required for their services. These differences among hospitals affect patients’ choices in hospital selection and result in different levels of satisfaction in the community. Appropriate subsidy mechanisms can be developed to balance the capacity utilization of both sectors and to improve overall access to healthcare. The objective of this study is to develop an estimate of the magnitude of this improvement and differential effectiveness of various policies in achieving this improvement. For this purpose, we develop a simulation model that includes all the emergency departments of main public and private hospitals in a certain region of Turkey. We analyze the effects of different public policies on patients’ preferences regarding hospital choices and the results of these choices on social utility and public healthcare spending. Different capacity decisions, contracting and subsidy mechanisms are proposed and the optimal system parameters are determined under these mechanisms over this simulation model. After the validation and verification of the simulation model, several scenarios are designed and executed to increase social utility, decrease government expenses, improve patient satisfaction level and decrease waiting times. We compare the proposed scenarios based on multiple objective functions and present numerical results for different scenarios in this system.  相似文献

Abstract Fiscal stimuli to recover? A cascade of academic and layman articles debate the effectiveness of fiscal policy in stimulating the economy backed up by different economic models and empirical support. This paper surveys the theoretical predictions and recent empirical vector autoregression evidence on the short‐run effects of discretionary fiscal policy on macroeconomic aggregates.  相似文献

Economic recessions are traditionally associated with asset price declines, and recoveries with asset price booms. Standard asset pricing models make sense of this: during a recession, dividends are low and the marginal value of income is high, causing low asset prices. Here, I develop a simple model which shows that this is not true during a recession caused by consumption restrictions, such as those seen during the 2020 pandemic: the restrictions drive the marginal value of income down, and thereby drive asset prices up, to an extent that tends to overwhelm the effect of low dividends. This result holds even if investors misperceive the economic forces at work.  相似文献

Public-private partnerships (PPPs) are widely spread long-term arrangements between governments and strategic private partner(s). One of their objectives is to reduce the financial pressure on the public treasury with regard to new investments. PPPs have been employed within the health care sector which, in turn, carries a huge social burden. In Portugal, for instance, PPPs in health care concern bundling hospital infrastructure and clinical services management. Notwithstanding the need to ensure sustainability and efficient use of hospital resources, it is clearly compulsory to guarantee that patients receive appropriate and timely care, with maximum security, and equitable manner. Still, little or even no attention has been paid in the literature to the clinical response capacity of PPP hospitals and to the populism arguing that these entities have a lower social performance than typical public hospitals. This study uses robust benchmarking methodologies alongside recent data about Portuguese hospitals (FY2012-FY2017) to demystify this idea and to demonstrate that, actually, PPP hospitals can deliver health care services with social performance levels at least as good as public hospitals.  相似文献

Assets are coupled to endogenous aggregate output fluctuations in a model of heterogeneous agents. Those agents wish to avoid reacting inadvertently to an unobservable noise process, but to do so must elicit reactions to that noise from each other. An abstract institution is modeled that optimizes this elicitation by strategically transmitting information about aggregates; I designate this feedback. Feedback is used by agents and so influences the characteristics of aggregate fluctuations. The optimal feedback policy minimizes asset rates of return, maximizes the persistence of aggregate output fluctuations, and causes the distribution of wealth to widen continually and without limit.  相似文献

There appears to be a paradox in the fact that as more and more quantitative information becomes routinely available in a world perceived to be ever more complex, there is less and less direct appreciation of the role and power of statistical thinking. It is suggested that the profession should exploit very real public concerns regarding risk aspects of public policy as a possible pedagogic route to raising statistical awareness.  相似文献

This paper presents a DSGE model in which agents׳ learning about the economy can endogenously generate time-varying macroeconomic volatility. Economic agents use simple models to form expectations and need to learn the relevant parameters. Their gain coefficient is endogenous and is adjusted according to past forecast errors.The model is estimated using likelihood-based Bayesian methods. The endogenous gain is jointly estimated with the structural parameters of the system.The estimation results show that private agents appear to have often switched to constant-gain learning, with a high constant gain, during most of the 1970s and until the early 1980s, while reverting to a decreasing gain later on. As a result, the model can generate a pattern of volatility, which is increasing in the 1970s and falling in the second half of the sample, with a decline that can roughly match the magnitude of the so-called “Great Moderation” in the 1984–2007 period. The paper also documents how a failure to incorporate learning into the estimation may lead econometricians to spuriously find time-varying volatility in the exogenous shocks, even when these have constant variance by construction.  相似文献

The number of new Covid-19 cases is still high in several countries, despite vaccination efforts. A number of countries are experiencing new and severe waves of infection. Therefore, the availability of reliable forecasts for the number of cases and deaths in the coming days is of fundamental importance. We propose a simple statistical method for short-term real-time forecasting of the number of Covid-19 cases and fatalities in countries that are latecomers—i.e., countries where cases of the disease started to appear some time after others. In particular, we propose a penalized LASSO regression model with an error correction mechanism to construct a model of a latecomer country in terms of other countries that were at a similar stage of the pandemic some days before. By tracking the number of cases in those countries, we use an adaptive rolling-window scheme to forecast the number of cases and deaths in the latecomer. We apply this methodology to 45 countries and we provide detailed results for four of them: Brazil, Chile, Mexico, and Portugal. We show that the methodology performs very well when compared to alternative methods. These forecasts aim to foster better short-run management of the healthcare system and can be applied not only to countries but also to different regions within a country. Finally, the modeling framework derived in the paper can be applied to other infectious diseases.  相似文献

Learning, monetary policy rules, and macroeconomic stability   总被引:1,自引:0,他引:1  
Several papers have documented a regime switch in US monetary policy from ‘passive’ and destabilizing in the pre-1979 period to ‘active’ and stabilizing afterwards. These studies typically work with DSGE models with rational expectations.This paper relaxes the assumption of rational expectations and allows for learning instead. Economic agents form expectations from simple models and update the parameters through constant-gain learning. In this setting, the paper aims to test whether monetary policy may have been a source of macroeconomic instability in the 1970s by inducing unstable learning dynamics.The model is estimated by Bayesian methods. The constant-gain coefficient is jointly estimated with the structural and policy parameters in the system.The results show that monetary policy was respecting the Taylor principle also in the pre-1979 period and, therefore, did not trigger macroeconomic instability.  相似文献

Buying services in a triad constellation is associated with challenges related to quality control, performance monitoring, and a deteriorating information position for the buyer. There is growing attention for service triads in Supply Chain Management (SCM) literature. However, these studies are mainly theoretical. The studies suggest to manage the identified challenges by monitoring supplier performance, maintaining a strong position in the service triad, developing collaborative trusting relationships, using outcome-based contracts, and aligning incentives between buyer and suppliers. Empirical studies on service triads and management mechanisms are rare, especially in a public procurement context. We study the application of management mechanisms in a public procurement context where 393 Dutch municipalities each had to contract social care service providers at the same time. This context allows us to study which of the management mechanisms proposed in literature are actually employed in a public procurement context, and whether other mechanisms are applied that are not addressed in the literature. We find municipalities deviate from traditional bureaucratic procurement procedures and apply a relational approach to the procurement procedure, including establishing social contracts, to cope with buyer challenges in service triads. Furthermore we identify municipalities apply ex post competition to drive up service quality through tendering framework agreements and allowing clients to choose their care provider of choice. This mechanism of ex post competition through the use of framework agreements has not been suggested in service triad literature before, and may be an effective mechanism in other service triads to address service quality and customer needs fulfilment issues.  相似文献

The job of the board of directors is the least developed element in enterprise, whether public, business, or nonprofit. Incorporating insights from Mill, Hume, and the social contract philosophy of Rousseau, as well as the servant-leadership concept of Greenleaf, the author's Policy Governance® model constitutes a theory of governance applicable to any governing body. The model enables public boards to govern by making public values explicit, crafting the expression of those values for practical managerial effect. The new governance model compels radical change in the way boards conduct their business. One effect is more authoritative boards and more empowered management simultaneously; another is greater integrity in the relationship between the public and its boards.  相似文献

The purpose of this paper is to analyze the determining factors of the high levels of NEETs both in EU member states and in partner countries, to support policy steering and increase socio-economic cohesion. The use of longitudinal data (2005–2020) from Eurostat and World Bank databases and selected and the testing of a number of 19 factors likely to influence the rate of NEETs show us that the effectiveness of public policy solutions focused on this category of population increases when complex factors and not singular elements are targeted. From a methodological point of view, we will use MARS models and fixed effects panel models. To account for countries’ heterogeneity, these models are applied to homogeneous groups of countries, identified through cluster analysis. Social cohesion and sustainability measures for policy steering have higher chances if the action of the responsible institutions targets both meso and macro levels, if it acts not only on a factor but also on the causes that favor its manifestation. Our analysis demonstrated that the measures aimed at increasing the chances of NEETs in order to facilitate their access to education, the labor market, and social inclusion must be coordinated with those of support for combating poverty and any type of exclusion, the support given to employers (subsidizing jobs, for example), the family and the community to which the young person belongs or local authorities. Also, the research results show us that there are more common elements between countries when we analyze the factors likely to increase the rate of NEETs than when we focus on their analysis by geographical criteria, based on EU membership status or EU partner status, etc.  相似文献
