The response of labour supply to negative shocks is different across regions due to varying levels of labour mobility. This column shows that the elasticity of labour supply in response to economic shocks is lower in the euro area than in the US, suggesting that a lack of labour mobility may be an obstacle to labour market adjustments in the euro area. Policies aimed at reducing the complexities of migrating for jobs could help ease this mobility gap.

Growth in life expectancy during the last two centuries has been attributed to environmental change, productivity growth, improved nutrition, and better hygiene, rather than to advances in medical care. This column traces the development of medical care and the extension of longevity in the US from 1800 forward to provide a long-term look at health and health care in the US. It demonstrates that the contribution of medical care to life-expectancy gains changed over time.

Escalating tensions between the US and its trading partners have made a global trade war more likely. In addition to the direct effect due to the increase in tariffs, a trade war may also affect GDP via indirect channels, such as a drop in productivity due to uncertainty and changes in the production environment. Using a multi-country model, this column shows that a global and generalised 10 percentage point increase in tariffs could reduce the level of global GDP by almost 2.0% on impact and up to 3.0% after two years, when all the additional indirect channels materialise.

Susan Dynarski of the University of Michigan discusses how a pilot scheme promising low-income high-school students four years of free tuition and fees if they were accepted on a university course more than doubled application rates.

Previous studies show that conventional factors, such as firm-specific and macroeconomic variables, do a poor job of explaining yield spread changes. Using data from the US corporate bond market, this column shows that over-the-counter frictions explain around 23% in the variation of the common component and one third of the total variation in yield spread changes. The combination of search and bargaining frictions is slightly more important for the dynamics of yield spread changes than inventory frictions. The findings are broadly consistent with leading theories of intermediation frictions in over-the-counter markets.

One version of Okun’s law specifies a relationship between the change in the unemployment rate and output growth. This column uses US labour market flows data to investigate this relationship between 1990 and 2017. It finds that the net flows between employment and unemployment are sensitive to changes in growth but respond differently to positive and negative changes. This implies that the US Okun relationship is stable but asymmetric, the effect of a change being larger in contractionary periods than in expansionary ones.

People combine goods and time in household production, and theory suggests that as their wage rates rise, they will substitute goods-intensive for time-intensive activities. However, it is not clear how activities that take essentially no, or minimal, amounts of spending, such as sleeping or watching TV, fit into the theory. This column uses data from time diaries for the US, France, and Germany to demonstrate that not all non-work time is the same, and different components of non-work time respond differently to changing incentives.

Europe is at risk of falling behind its global competitors. In a period of radical technological transformation, European firms are investing too little, with a gap both in tangible and intangible investment compared to the US. This column calls for a ‘retooling’ of Europe’s economy in relation to skills, innovation finance, the business environment, infrastructure, and deepening the Single Market.

Negative sentiment towards immigrants is often based on fears about their ability to integrate into economic, political, and social institutions. This column analyses the impact of the influx of Irish immigrants into the US in the 19th century. It shows that the children of immigrants had assimilated in terms of labour market outcomes within one generation, providing some perspective for the current debate about immigration policy.

Both healthcare spending levels and growth in the US have exceeded other developed countries for many years. With healthcare costs rising at an unsustainable pace, a greater percentage of workers in the US are being enrolled in high-deductible health plans. This column estimates the relationship between high deductibles and the growth in total healthcare spending on all medical goods and services. It finds that deductible levels have a considerable effect on spending growth, and suggests that the natural next step is to explore whether or how that affects health outcomes.

The American Dream is grounded in the US being the land of opportunities, but real opportunity requires mobility across generations. This column examines the influence of parents’ income on the income of their children in the US for the period 1980-2010. Parental income has a greater influence, implying lower levels of mobility, for families with the highest and lowest levels of income. Education also plays a stronger role in economic persistence at both tails of the income distribution, while race affects mobility in the middle and lower parts of the distribution.

Unlike income inequality, wealth inequality along racial lines in the US has received relatively little attention. This column presents new evidence on the changing landscape of relative wealth among whites, blacks, and Hispanics between 1983 and 2016. Using an augmented measure of wealth, it highlights how cuts to social security will disproportionately affect minorities.

There have been many calls to increase the racial and gender diversity of teachers in US primary and secondary schools, with the evidence to date showing that improving the match between student and teacher demographics has significant positive effects on test scores. This column looks at the longer term effects of such changes. Random assignment to a black teacher in grades K–3 increased the chances that black students graduated from high school and enrolled in college.

Short-term rental platforms such as Airbnb have grown spectacularly in recent years, and local governments around the globe have responded differently in regulating such rentals. This column analyses the effects of a policy change in several cities of Los Angeles County that restricted short-term rentals of entire homes and apartments. Airbnb has led to an increase in house prices that is particularly pronounced in popular tourist areas, and homeowners in these areas lose out from the regulation. Renters, on the other hand, benefit from the regulation.

There is an ongoing debate regarding how far central bankers, as unelected technocrats, should go outside of their remit when communicating in public fora. This column uses a machine-learning algorithm to assess the topics of speeches by officials at the US Federal Reserve and Bank of Canada over the last two decades. It concludes that the topics of central bankers’ speeches have not significantly widened in scope relative to their mandate documents.

Risk taking was pervasive during the Global Crisis even in the most unlikely areas, such as stretching to lend at a distance. Using US data, this column examines the degree to which competition amongst lenders interacts with the cyclicality in lending standards using a simple and policy-relevant measure, the average physical distance of borrowers from banks’ branches. It finds that distances widen considerably when credit conditions are lax and shorten considerably when credit conditions become tighter. A sharp departure from the trend in distance between banks and borrowers is indicative of increased risk taking.

Countries that vote with the US when serving on the UN Security Council also receive more financial assistance. This column uses voting records in the Council to show that when these countries were US allies, they received more in US aid, but when the countries were not natural allies, they received more financial assistance from US-dominated international institutions instead.
