Life expectancy in the United States fares poorly in international comparisons, primarily because of high mortality rates above age 50. Its low ranking is often blamed on a poor performance by the health care system rather than on behavioral or social factors. This paper presents evidence on the...

This paper offers a thesis as to why the US overtook the UK and other European countries in the 20th century in both aggregate and per-capita GDP, as a case study of recent models of endogenous growth where human capital is the "engine of growth". The conjecture is that the ascendancy of the US...

We analyze a 1960-96 panel of OECD countries to explain why the US moved from relatively high to relatively low unemployment over the last three decades. We find that while macroeconomic and demographic shocks and changing labor market institutions explain a modest portion of this change, the...

This paper investigates the potential reasons for the surprisingly different labor market performance of the United States, Canada, Germany, and several other OECD countries during and after the Great Recession of 2008-09. Unemployment rates did not change substantially in Germany, increased and...

Wages have been spreading out across workers over time - or in other words, the 90th/50th wage ratio has risen over time. A key question is, has the productivity distribution also spread out across worker skill levels over time? Using our calculations of productivity by skill level for the U.S.,...

We summarize the economics of recycling municipal solid waste. OECD data suggest that aggregate recycling rates in member countries have plateaued in recent decades. United States recycling rates for some materials remain low, even after decades of learning and participation. Major new policies...

Startups in IT and life sciences appear to be flourishing. However, startups in other sectors, such as new materials, automation, and eco-innovations, which are often called "deep tech", seem to struggle. We argue that innovations with both technical and commercial challenges, typical of deep...
