Following the collapse of Lehman Brothers, there was a fall in growth rates of net banking credit and total net new bond issues. This column discusses these events in detail. It also suggests that the decrease in credit was mainly due to supply shrinkage. The persistence of credit arrest beyond the two years following Lehman’s collapse is due to gradual enactment of tougher banking regulations along with growing awareness of low bailout probabilities.

Pollution levels are orders of magnitude higher in lower-income countries than in the developed world. This means that studies of the health effects of pollution based on data from the latter will not necessarily be relevant to the former. This column reports on the effect of air pollution on infant mortality in Mexico City. Significant effects are found that are much larger than found in earlier work based on US data. These findings highlight the potential pitfalls of naively extrapolating findings from high-income to developing countries.

Both the US and the Eurozone reacted to the Global Crisis by injecting liquidity and loosening monetary policy. This column argues that despite the similarities in the behaviour of bank credit, the behaviour of bank reserves has been quite different. In particular, while US bank reserves have been on an uninterrupted upward trend since Lehman’s collapse, EZ bank reserves have fluctuated markedly in both directions. At the source, this is due to differences in the liquidity injections procedures between the Eurozone and the Fed.

The quantity theory of money implies that sustained inflation requires a sustained increase in the money supply. It does not, however, imply that the reverse is also true. This column explores and illustrates this issue by comparing inflation in the US following the collapse of Lehman Brothers with Germany’s hyperinflation experience after WWI. A key factor explaining the vastly different inflation experiences is how the monetary expansion translated into demand. The Fed’s base expansion did not translate into demand for goods and services, whereas the German monetary expansion was motivated by the government’s hunger for seigniorage revenues.

Recent evidence suggests that transformational entrepreneurial firms – those that introduce major innovations and make substantial contributions to growth – have been in decline. This column uses US micro data to explore the behaviour of high-growth young firms between 1980 and 2010. A decline in young firm activity in the 1980s and 1990s was dominated by young firms in the retail trade sector. In the post-2000 period, in contrast, a sharp decline in high-growth young businesses in key innovative sectors like high tech suggests there has been a decline in transformational entrepreneurs in this sector.

Since the Global Crisis, a key ingredient of reforms has been to force over-the-counter contracts to be traded in more transparent exchange-like settings. The aim has been to reduce the cost of trading such instruments and make markets more resilient. This column analyses the impact of the Dodd-Frank Act in the US on the market for vanilla interest rate swaps. The introduction of swap execution facilities trading is associated with a significant improvement in swap market liquidity. This suggests that Europe may see similar benefits from centralising swap trading, though it remains to be seen how these markets will operate in more volatile times.

Prior to the Global Crisis, banks could easily use off-balance sheet structures to lower their effective capitalisation rates. This column examines another way that US banks circumvented capital regulations – by maintaining minority-owned, non-consolidated subsidiaries. Had these subsidiaries been consolidated, average reported equity-to-assets ratios would have been 3.5% lower. These findings suggest that some US banks were actively misrepresenting the riskiness of their assets prior to the crisis.

The Great Depression is considered one of the darkest times for the US economy, but some argue that the US economy experienced strong productivity growth over the period. This column reassesses this performance using improved measures of total factor productivity that allow for comparisons of productivity growth in the Depression era and in later decades. Contrary to Alvin Hansen’s gloomy prognosis of secular stagnation, the US economy was in a very strong position during the 1930s by today’s standards.

Many observers believe that pharmaceutical firms prefer to invest in drugs to treat diseases rather than vaccines. This column presents an economic rationale for why such a pattern may emerge for diseases like HIV/AIDS. The population risk of such diseases resembles a Zipf distribution, which makes the shape of the demand curve for a drug more conducive to revenue extraction than for a vaccine. Based on revenue calibrations using US data on HIV risk, the revenue from a drug is about four times greater.

Concerns about both the level of bond market liquidity and its fragility have risen lately, prompted partly by events such as the October 2014 Treasury bond flash rally in the US, or the April 2015 Bund tantrum in Europe. This column assesses current market liquidity and resilience, discerning several key policy recommendations from the evidence.

Studies of the effects of economic fluctuations on health have come to wildly different conclusions. This may be because the effects are different for different groups. Using US data, this column looks at the health consequences of the Great Recession on mothers, a sub-population that has thus far been largely neglected in the literature. Increases in unemployment are found to have large negative health effects and to increase incidences of smoking and substance abuse among mothers. These effects appear to be concentrated on disadvantaged groups such as minorities, and point to short- and long-term consequences for their children.

Tax policy varies widely across countries and across regions within countries. This column presents evidence suggesting that in the case of the US, harmonising tax rates could lead to significant increases in aggregate economic output. EU policymakers should take note.

The recent influx of refugees to Europe has stoked security fears and created anxiety about the social and economic consequences. This column provides new quantitative indicators for the intensity of migration-related fears and policy uncertainty, based on newspaper articles. The indices are presented for the US, UK, France, and Germany, and extend back to 1995. They show that recent levels of concern and uncertainty in European countries about migration are unprecedented.

The globalisation of innovation is proceeding at a fast pace. This column argues that the ethnic composition of a firm’s US-based inventive work force is an important factor in whether the firm engages in international collaborations. Collaborative patents are often utilised when a US public company is entering into a new foreign region for innovative work. This is especially notable in markets with weak intellectual property protections.

We traditionally think of migrants draining their home country of knowledge and skills, and, instead, giving their all to their host country. Based on patent and inventor data, this column looks at knowledge diffusion conveyed by highly skilled migrants both within their host country as well as back to their homelands. China, South Korea and Russia seem to profit from their diaspora’s knowledge generation but the same can’t be said for India.

In the years running up to the global crisis, the banking sector was marked by a high degree of leverage. Using US data, this column shows how, before the onset of the crisis, banks accumulated leverage both on and, especially, off their balance sheets. The latter activities saw an increase in maturity mismatch, raised the probability of bank runs, and increased both individual bank risk and systemic risk. These findings support the imposition of an explicit off-balance sheet leverage ratio in future regulatory frameworks.

In light of the Great Recession, we continue to learn new ways in which economic downturns directly affect the labour market. This column suggests that following an adverse demand shock, individuals exit local labour markets primarily through migration, but that has become less prominent in the Great Recession. Faced with declining economic prospects, workers are becoming more likely to stay put, without re-entering the labour market.

Fracking has driven an oil and natural gas boom in the US over the past decade. This column examines the impact these mining activities have had on local and regional economies. US counties enjoy significant economic benefits, including increased wages and new job creation. These effects grow as the geographic radius is extended to include neighbouring areas in the region. The results suggest that the fracking boom provided some insulation for these areas during the Great Recession, and lowered national unemployment by as much as 0.5%.

Voluntary disclosure programmes offer tax evaders the opportunity to come clean with reduced penalties. This column uses data from the US and Germany to examine the merits of such programmes. They are found to increase tax evasion, but also to significantly lower administrative costs, leading to a net increase in tax revenues.

Much research has gone into trying to establish a connection in the US between having a distinctively black name and disadvantage over a lifetime. This column highlights a striking difference between the historical effects of having a black name and today’s effects. While modern black names show up in modern empirical studies as an albatross around the neck of those possessing them, either because those with such names come from worse socioeconomic conditions or face discrimination later in life, historical black names conveyed a large advantage accumulating over an individual’s lifetime.
