Utilising a new sample of interwar initial public offerings (IPOs), I consider the effectiveness of the interwar stock market for firms going public. Consistent with the pecking order theory, IPO proceeds contributed only modestly to domestic industry's capital expenditure needs. IPOs of capital-hungry new manufacturing industries raised no more finance than did the rest of manufacturing. This was in part attributable to the detrimental effect of weak financial regulation on investor appetite for newer, riskier enterprises. In terms of the quality of firms allowed onto the market, IPO survival rates of the early and late 1920s were shockingly low, just as earlier research has shown. However, survival rates rebounded strongly in the following decade due not only to the economic recovery but also to tougher scrutiny of listing applications by the London Stock Exchange.

31 In line with previous IPO studies, issues by firms already listed on another stock exchange, investment trusts, and introductions are excluded. Penny shares, or shares with an offer price of 2 shillings or less, are also excluded. Such issues were characteristic of speculative mining and rubber share counters.

35 The Midland Bank Review estimated total new issue proceeds at £1,700 m. The difference is represented by SEO proceeds, which for reasons discussed above, I am unable to include in this sample.
36 The Economist index of business activity fell by 35% between July 1920 and June 1921. The fact that the share price index did not show a similar sharp fall at this time reflects the lack of a pure ordinary share index series prior to the establishment of the Financial News 30 index in January 1930.
37 There were only 38 common stock IPOs between 1934 and 1938. Gompers, P. and Lerner, J., ‘The really long-run performance of initial public offerings: the pre-Nasdaq evidence’, Journal of Finance, 58 (2003), p. 1360CrossRefGoogle Scholar, table 1.

40 As a further check, I made use of prospectus disclosure regarding whether a firm engaged in research and development activity. There were only 49 such firms in the sample, but these firms were highly correlated with the new manufacturing industrial classification.
41 I am grateful to Mike Staunton for providing this data.
42 The Companies Acts of 1900 and 1907 required public companies to publish a balance sheet. However, many companies only converted to public company status immediately prior to their IPO, and, therefore, would have escaped this requirement at IPO.

44 This approach follows Henderson, New Issue Market, in excluding long-term, but not short-term, debt repayment. Bank overdrafts represent short-term funding of capital expenditure in anticipation of the subsequent equity issue. However, overdrafts used to fund an acquisition are excluded.
