Collective hallucinations and inefficient markets: The British Railway Mania of the 1840s Andrew Odlyzko School of Mathematics and Digital Technology Center University of Minnesota [email protected] http://www.dtc.umn.edu/∼odlyzko Preliminary version, January 15, 2010 Abstract. The British Railway Mania of the 1840s was by many measures the greatest technology mania in history, and its collapse was one of the greatest financial crashes. It has attracted surprisingly little scholarly interest. In par- ticular, it has not been noted that it provides a convincing demonstration of market inefficiency. There were trustworthy quantitative measures to show in- vestors (who included Charles Darwin, John Stuart Mill, and the Bront¨esisters) that there would not be enough demand for railway transport to provide the ex- pected revenues and profits. But the power of the revolutionary new technology, assisted by artful manipulation of public perception by interested parties, in- duced a collective hallucination that made investors ignore such considerations. They persisted in ignoring them for several years, until the lines were placed in service and the inevitable disaster struck. In contrast to many other bubbles, the British Railway Mania had many powerful, vocal, and insightful critics. But the most influential of them suffered from another delusion, which misled them about the threat the Mania posed. As a result, their warnings were not persuasive, and were likely even counter- productive, as they may have stimulated increased investments. The delusions that led to the financial disaster of the Railway Mania arose from experience with the railway mania of the mid-1830s. Seldom even men- tioned in the literature, it was about half the size of the big Railway Mania of the 1840s (and thus still far larger than the Internet bubble). The initial finan- cially exuberant phase of it did collapse. But it appears to have been unique among large manias in that a few years later it was seen as having collapsed prematurely, as projects started during its exuberant phase became successful. That mania demonstrates the difficulty in identifying bubbles that are truly irrational. Both railway manias provide a variety of other lessons about the interaction of technology and financial markets. – Main text: 187 pages. – Appendices: 63 pages. – Endnotes: 54 pages.

At its height, individual capital- ists, in pursuit of private profit, were plowing more than twice as much into the construction of a public infrastructure as their nation was spending on the military. (It should be noted that the Pax Britannica was not cheap. Among other foreign adventures, Britain had just a few years earlier been involved in the First Opium War and the First Afghan War.) During the peak year for spending, 1847, their investments came, as a fraction of Gross Domestic Product (GDP), to the equivalent of over $1 trillion dollars for the United States today. (If we compare their expenditure to total government spending, federal, state, and local, and not to GDP, it was equivalent to over $3 trillion dollars. Taxes, which might be thought of as proportional to discretionary incomes, were far lower at that time than today.) All the funding came from individuals making private decisions to commit their funds to the new enterprise. Those investors, most new to share markets, involved such scientific and literary luminaries as Charles Darwin, Charles Babbage, John Stuart Mill, the Bront¨esisters and William Makepeace Thackeray, as well as such prominent politicians (directly or through their close families) as Disraeli, Gladstone, Palmerston, and Peel. Many famous figures were involved with the Mania in other ways. For example, Herbert Spencer, in an early stage of his career, was a railway engineer during the financially most exuberant phase of the Mania. While he appears not to have invested in it himself, he managed to persuade his father to sell out close to the peak of the market. Most investors did not fare so well, and their hopes for bountiful profits were grievously disappointed. The peak of the Mania excitement was followed by several years of heavy investment accompanied by a slow and agonizing slide in the stock markets. At the end of 1849, just as railway shares were touch- ing their lowest level of that decade (and of the remaining decades of the 19th century), Charlotte Bront¨ewrote: My Shares are in the York & North Midland Railway. ... The original price of Shares in this Railway was £50. At one time they rose to 120; and for some years gave a dividend of 10 per cent; they are now
