Lockdown policies have been found to be effective in promoting social distancing and slowing down the spread of COVID-19. Yet, such measures are often blamed for downturns in the economy. This column argues that the lockdowns in the US are in fact efficient in minimising the costs of the epidemic, once both the economic and medical burden that would arise in the absence of such policies are considered. Estimates from a controlled SIR model, which includes the possibility for changes in behaviour, suggest that lockdowns reduce the costs of the pandemic by at least 1.7% of annual GDP compared to a no-lockdown scenario.

Despite the prevalence of industrial policies around the world, few empirical studies directly evaluate their welfare consequences. This column reveals that the scale of China’s industrial policy targeting the shipbuilding industry is massive, with the lion’s share going to entry subsidies. The effectiveness of different policy instruments is mixed, and the efficacy of industrial policy is significantly affected by the presence of boom and bust cycles, and by heterogeneity in firm efficiency. The ‘white list’ of firms chosen for government support did not include the most efficient firms.

Container shipping is considered to be one of the drivers of globalisation. This column uses micro-level data to show evidence that confirms the role of 'the box' in the global economy: it implies significant cost savings and explains a significant amount of the global trade increase since its inception. The results also suggest that most of its trade-increasing effect has already been realised.

In choosing their hospital, patients are concerned with both quality of care and amenities such as comfortable rooms. This column summarises recent research showing that patients value amenities and more productive hospitals compete for patients by supplying higher quality. We need to assess the value of amenities in relation to other hospital benefits, since improving amenities is more costly than improving care.
