The British government has been debating how and when to escape from the lockdown without provoking a resurgence of the Covid-19 disease. There is a growing recognition of the damage the lockdown is causing to economic and social life, including deaths and illness amongst the non-infected population. This paper presents a simple cost-benefit analysis based on optimal control theory and incorporating the SIR model of disease propagation. It concludes by presenting some simulations informed by the theoretical discussion. The main conclusions are: (1) the lockdown should be continued for some weeks, and (2) if there is an inexpensive way of reducing the net reproductive rate of the disease to r = 1, this policy should be adopted within a few weeks of exiting lockdown. It is not cost-effective to linger in intermediate stages with more expensive policies designed to keep r well below...

We construct a quantitative model of an economy hit by an epidemic. People differ by age and skill, and choose occupations and whether to commute to work or work from home, to maximize their income and minimize their fear of infection. Occupations differ by wage, infection risk, and the productivity loss when working from home. By setting the model parameters to replicate the progression of COVID-19 in South Korea and the United Kingdom, we obtain three key results. First, government-imposed lock-downs may not present a clear trade-off between GDP and public health, as commonly believed, even though its immediate effect is to reduce GDP and infections by forcing people to work from home. A premature lifting of the lock-down raises GDP temporarily, but infections rise over the next months to a level at which many people choose to work from home, where they are less productive, driven...

Policy makers responding to COVID-19 need to know people’s relative valuation of health over wealth. Loosening and tightening lockdowns moves a society along a (perceived) health-wealth trade-off and the associated changes have to accord with the public’s relative valuation of health and wealth for maximum compliance. In our survey experiment (N=4,618), we randomize information provision on economic and health costs to assess public preferences over this trade-off in the UK and the US. People strongly prioritize health over wealth, but the treatment effects suggest these priorities will change as experience of COVID-19 deaths and income losses evolves. Information also has heterogeneous/polarizing effects. These results encourage policy caution. Individual differences in health-wealth valuation highlight this study’s importance because they map onto compliance with current lockdown...

We nowcast the economic effects of the Covid-19 pandemic and related lockdown measures in the UK and then analyse the distributional and budgetary effects of the estimated individual income shocks, distinguishing between the effects of automatic stabilisers and those of the emergency policy responses. Under conservative assumptions about the exit strategy and recovery phase, we predict that the rescue package will increase the cost of the crisis for the public budget by an additional £26 billion, totalling over £60 billion. However, it will allow to contain the reduction in the average household disposable income to 1 percentage point, and will reduce poverty rate by 1.1 percentage points (at a constant poverty line), with respect to the pre-Covid situation. We also show that this progressive effect is due to the increased generosity of Universal Credit, which accounts for only 20%...

Social distancing is a matter of individuals’ choices as well as of regulation, and regulation arguably responds to those choices. We analyse weekly panel data on such behaviour for English Upper Tier Local Authorities (UTLAs) from March to July 2020, paying attention to the influence of poverty, as measured by free school meals provision. Panel regressions suggest that, although more stringent regulation and slightly lagged local cases of infection increase social distancing, both effects are weaker in UTLAs with higher levels of poverty. Thus motivated, we develop a two-class (rich/poor) model, in which a Nash non-cooperative equilibrium arises from individual choices in a regulatory regime with penalties for non-compliance. The model yields results in keeping with the empirical findings, indicating the desirability of generous measures to furlough workers in low-paid jobs as a...

We explore impacts of the pandemic crisis and associated restrictions to economic activity on paid and unpaid work for men and women in the UK. Using data from the Covid-19 supplement of Understanding Society, we find evidence that labour market outcomes of men and women were roughly equally affected at the extensive margin, as measured by the incidence of job loss or furloughing, but if anything women suffered smaller losses at the intensive margin, experiencing slightly smaller changes in hours and earnings. Within the household, women provided on average a larger share of increased childcare needs, but in an important share of households fathers became the primary childcare providers. These distributional consequences of the pandemic may be important to understand its inequality legacy over the longer term.

This paper analyses the costs and benefits of lockdown policies in the face of COVID-19. What matters for people is the quality and length of lives and one should measure costs and benefits in terms of those things. That raises difficulties in measurement, particularly in valuing potential lives saved. We draw upon guidelines used in the UK for public health decisions, as well as other measures, which allow a comparison between health effects and other economic effects. We look at evidence on the effectiveness of past severe restrictions applied in European countries, focusing on the evidence from the UK. The paper considers policy options for the degree to which restrictions are eased. There is a need to normalise how we view COVID because its costs and risks are comparable to other health problems (such as cancer, heart problems, diabetes) where governments have made resource...

The British government has been debating how to escape from the lockdown without provoking a resurgence of the COVID-19 disease. There is a growing recognition of the damage the lockdown has caused to economic and social life. This paper presents a simple cost-benefit analysis inspired by optimal control theory and incorporating the SIR model of disease propagation. It also reports simulations informed by the theoretical discussion. The optimal path for government intervention is computed under a variety of conditions. These include a cap on the permitted level of infection to avoid overload of the health system, and the introduction of a test and trace system. We quantify the benefits of early intervention to control the disease. We also examine how the government’s valuation of life influences the optimal path. A 10-week lockdown is only optimal if the value of life for COVID-19...

In responding to covid-19, governments have tried to balance protecting health while minimising Gross Domestic Product (GDP) losses. We compare health-related net benefit (HRNB) and GDP losses associated with government responses of the UK, Ireland, Germany, Spain, and Sweden from UK healthcare payer perspective. We compared observed cases, hospitalisations, and deaths under “mitigation” to modelled events under “no mitigation” to 20th July 2020. We thus calculated healthcare costs, quality adjusted life years (QALYs), and HRNB at £20,000/QALY saved by each country. On per population (i.e. per capita) basis, we compared HRNB with forecast reductions in 2020 GDP growth (overall or compared to Sweden as minimal mitigation country) and qualitatively and quantitatively described government responses. The UK saved 3.17 (0.32-3.65) million QALYs, £33 (8-38) billion healthcare costs, and...

The COVID-19 response required the cancellation of all but the most urgent surgical procedures. The number of cancelled surgical procedures owing to Covid-19, and the reintroduction of surgical acivirt, was modelled. This was a modelling study using Hospital Episode Statistics data (2014-2019). Surgical procedures were grouped into four urgency classes. Expected numbers of surgical procedures performed between 1 March 2020 and 28 February 2021 were modelled. Procedure deficit was estimated using conservative assumptions and the gradual reintroduction of elective surgery from the 1 June 2020. Costs were calculated using NHS reference costs and are reported as millions or billions of euros. Estimates are reported with 95 per cent confidence intervals. A total of 4 547 534 (95 per cent c.i. 3 318 195 to 6 250 771) patients with a pooled mean age of 53.5 years were expected to undergo...
