House Prices since 1870

Katharina Knoll, Moritz Schularick and Thomas Steger have a really nice paper and Vox column looking at house prices for 14 economies from 1870 to 2012. They find that house prices stayed constant from 1870 to circa 1950, but rose strongly in the second half of the twentieth century. They also find that it is increasing land prices, not construction costs, which have driven this increase. Notably, their findings imply that real house price growth has outpaced income growth by a substantial margin.

Strangely, Knoll et al. do not explicitly acknowledge the relationship between the great mortgaging, which Schularick identified in previous work, and this increase in house prices (see previous post on this). For me, this explains a large part of what they find, particularly the large increase from the late 1990s. Instead, they argue that land increasingly became a fixed factor due to a land-augmenting decline in transport costs from circa 1950 onwards. In addition, zoning regulations on land use may have further restricted the supply of land.

The Economics of Global Warming

The Berkeley Earth Project , an independent study of global warming, has found that the earth has become a degree warmer over the past half century. However, the statistical uncertainty surrounding pre-1920 estimates makes it very hard to say much about long-term trends - click here for graph . This is one of my concerns with the global warming debate - we simply don't have trustworthy long-run data which looks at temperature changes over the last millennium (or two). My second concern with the global warming debate is that it is very hard to prove any sort of casual link between global warming and human activity. The scientists may be able to show correlation between global warming and our production of carbon dioxides etc., but correlation is not causation. My third concern with the debate is that those who are sceptical or agnostic are stereotyped as flat-earthers or intellectually-challenged crackpots. This only stifles debate and the progress of science itself.

The Failure of Herstatt Bank

As an undergraduate, I was taught about the failure of Herstatt Bank in 1974 and Herstatt risk. This bank was only the 35th largest bank in Germany at the time so why would anyone be interested in studying its failure? Herstatt failed because of its involvement in risky foreign exchange business. When it closed its doors on 26 June 1974, counterparty banks (mainly in New York) had not received dollars due to them because of time-zone differences - this is known as settlement risk. The cross-jurisdictional implications of its failure resulted in the Bank for International Settlements setting up the Basel Committee on Banking Supervision and Herstatt's failure was a key reason for the establishment of real-time gross settlements systems, which ensures that payments between two banks are executed in real time. The Bank of England's Ben Norman has an interesting post on Herstatt over at the Bank's new blog ( Bank Underground ). As well as giving an excellent overview of
