In the US, most patients who need a kidney transplant must participate in a centralised deceased-donor kidney allocation mechanism. The allocation system seeks to make the best use of available organs and maximise ‘life years from transplant’. This column estimates the life years from transplant generated by the US kidney assignment system, using data on transplants and outcomes for patients on the waiting list between 2000 and 2010. Patient choice to reject or accept the transplant increases life years from transplant. The policy goal to maximise life years from transplant would result in younger, healthier patients receiving transplants at the expense of older, more urgently sick patients.

The Covid-19 pandemic has exposed the fragility of the global trade network underpinning global value chains. Initial disruptions in the supply chains for key medical goods due to surges in demand and newly erected trade barriers have prompted policymakers around the world to question their country’s reliance on foreign suppliers and international production networks. This column takes a closer look at China’s post-pandemic recovery and argues that its response may hold clues to the future of global value chains.

Elections can cause economic uncertainty, especially when elections take place in a politically polarised context. This column studies how national election cycles in 23 countries influence economic policy uncertainty, as measured by the share of newspaper articles that discusses uncertainty and economic policy. Economic policy uncertainty clearly rises in the months leading up to national elections. Average economic policy uncertainty values are 13% higher in the month before and the month of national elections than in other months during the same election cycle. In the US, economic policy uncertainty increases are especially pronounced around close and highly polarised presidential elections.

Opioid misuse in the US is estimated to cost over $500 billion annually, with fatalities from opioid overdoses exceeding the American death count from the Vietnam War. This column examines the causes and consequences of the opioid crisis, based on a review of more than 100 economic studies. Policies such as prescription drug monitoring programmes, pill mill laws, prescribing limits, and doctor-shopping laws reduce opioid prescribing. However, their effects may be more limited in environments where many have already become addicted to opioids.

The global pandemic has exacerbated the gender pay gap for many, but not all, advanced economies. This column examines evidence from eight countries to show that certain policy responses to the pandemic have better served women’s participation in the labour force than others – notably those tailored to flexible working to accommodate home and childcare responsibilities, as well as those serving industries with greater participation by women. Such policies should be taken into account, especially as historically the reintegration of women into the labour force can take time after a crisis.

Many higher learning institutions have shifted to remote learning in response to the COVID-19 pandemic. Although research has found that online classes can be just as effective as in-person classes, there is evidence that suggests disadvantaged students may perform relatively worse. This column compares student performance on a set of standard assessments at four PhD-granting institutions in the US before and after the switch to online classes. It finds little evidence that disadvantaged groups were further disadvantaged by the pandemic in their college learning. Instructor experience with online teaching and the use of active-learning techniques have a positive effect on student outcomes.

Balancing the trade-off between strict public health measures and economic activity has been the key concern for governments since the Covid-19 outbreak. This column studies Covid-19 infections and their connectedness across US states.  It finds that states with lax government policy and community mobility response had higher case growth trajectories and generated connectedness of Covid-19 cases to other states.  Further, states with Republican governors tend to have higher connectedness of Covid-19 cases among themselves and generate net connectedness to states with Democratic governors.

As the COVID-19 pandemic continues worldwide, policymakers are still grappling with the question of which non-pharmaceutical policy interventions are effective. In the US, state and county policies varied widely, as did the growth in fatalities due to COVID-19. This column examines US business policies to help shed light on which policies save more lives. Stay-at-home orders, mandatory mask requirements, beach and park closures, restaurant closures, and high-risk (Level 2) business closures most consistently predict lower fatality growth four to six weeks ahead. Closures of low- and medium-risk businesses do not appear effective and, despite their costs, may even be counterproductive.

Transmission of monetary policy depends to a large extent on the phase of the housing cycle. This is because residential property prices are important determinants of banks’ willingness to lend. This column presents analysis for the US which shows that in the mature phase of the housing market boom, or immediately after a bust began, the effects of a monetary expansion were smaller than they were earlier in the housing cycle. This is relevant for central banks which are considering responding to the Covid-19 pandemic by easing monetary policy during a period of relatively high house prices.

Foreign direct investment flows to the US have seen a sharp decline in the past two years, despite a cut in the corporate tax rate from 35% to 21% in 2017. Previous research suggests that such a tax cut should have resulted in increased investor appetite. This column argues that countervailing forces, in particular the shift in investment sentiment driven by the corrosion of US openness to trade and global cooperation, have played the dominant role in reducing flows.

Similar levels of income inequality may coexist with completely different distributions of capital and labor incomes. This column introduces a new measure of compositional inequality, allowing the authors to distinguish between different capitalist societies. The analysis suggests that Latin America and India are rigid ‘class-based’ societies, whereas in most of Western European and North American economies (as well as in Japan and China), the split between capitalists and workers is less sharp and inequality is moderate or low. Nordic countries are ‘class-based’ yet fairly equal. Taiwan and Slovakia are closest to classless and low inequality societies.

Holding large rallies is an especially important campaign activity for many populist leaders, including for Donald Trump during the 2016 US presidential race. This column studies the effect of campaign rallies held by Democratic and Republican US presidential candidates since 2008, including Donald Trump. It explores the effect of rallies on citizens’ preferences over candidates, policy issues, and their intention to vote. Populist leaders may be particularly effective in gaining support via their campaign rallies, at least temporarily. Populist leaders’ success may depend on connecting with voters via rallies.

Could restrictions at the federal level have slowed the spread of COVID-19 in the US? This column addresses this question using a novel, multi-region epidemiological model that calculates the number of deaths that would have resulted from the federal government mirroring the policies of those states with the earliest and most rigorous restrictions. It finds that by late September 2020, more than two-thirds of the country’s COVID-19 deaths could have been prevented,highlighting the need for unified action from state and federal regulators.

In conflicts, adversaries aim for victory by using both direct and indirect forces to break the enemy’s will to resist. During WWII, Allied forces used strategic bombing and radio propaganda to undermine German morale. This column compares German domestic resistance to the Nazi regime, based on treason trial records, with the monthly volume of bombing and the locations of BBC radio transmitters. Where radio reception was better and Allied air forces bombed more heavily, German domestic resistance was markedly more likely, despite the draconian punishments for even the mildest transgressions.

The Covid-19 crisis has profoundly affected employment everywhere, but countries have adopted different strategies to try to mitigate the worst of the effects. This column compares the Greek experience to the rest of Europe, as well as to North America. The authors conclude that given the nature of the pandemic, models for managing labour market shocks will need to offer extended support where the shock persists or reoccurs. Crucially, successful policy approaches will need to be well suited for enabling job creation once conditions are in place for a restart.

How much can redistribution policies account for long-run changes in inequality? This column reveals that the reduction of inequality implied by redistribution is significant in France and the US and increased throughout the entire 20th century, but pre-tax income inequality appears to be the main factor accounting for the differential levels and trends in the two countries. These findings suggest that policy discussions on inequality should pay more attention to policies affecting pre-tax inequality and should not focus exclusively on redistribution.

The correlation between mental illness and crime has been widely documented. In general, individuals with poor mental health are more likely to be involved with crime, either as an offender or as a victim, compared to other individuals. This column presents evidence from the US, arguing that policies that grant support to mental healthcare may have long-term positive effects on crime rates. Since crime is a complex outcome, a flexible and varied policy response is essential to tackling the issue.

Mortgage markets are dynamic in nature, which sometimes comes at a cost. This column shows that over the last few decades, the US mortgage market experienced a secular decline in co-borrowers. Having a co-borrower minimises the exposure and effects of adverse income shocks and thus should enhance mortgage performance. The authors show that this yet unexplored decline in co-borrowers therefore has non-trivial implications for the financial stability of the mortgage market and regional economic outcomes.

The Covid-19 pandemic has had major political consequences. The balancing act of curbing the spread of the virus and re-opening the economy has been a particularly high-profile challenge for policymakers in recent months. This column explore the political costs of (mis-)managing the pandemic. The findings suggest that governments are punished in terms of political approval when Covid-19 infections accelerate, particularly in the absence of effective lockdown measures. Economic indicators, in contrast, do not appear to be strong predictor of political approval rates during this crisis.

In the last years, there has been substantial pushback against the patent system. Critics claim that patent rights are becoming an impediment to innovation, and an instrument to extract rents through patent litigation. This column develops a framework to quantitatively assess the effectiveness of the current US patent system and the welfare impact of reforms. It finds that the current system generates positive social value, and that the recent introduction of the Patent Trial and Appeal Board increased welfare. Intensifying patent office examination and imposing antitrust limits on patent licensing agreements would yield additional welfare gains.
