We test the effect of going public on economic growth in the areas surrounding initial public offering (IPO) firms. We compare the effects of IPO filers that complete their IPOs with those that do not, using post-filing stock market fluctuations as an instrument for IPO completion. We show that IPOs that are large relative to the size of their counties lead to a 1.1 percentage point relative reduction in annual county-level establishment growth, with similar effects for employment and population growth. There are no corresponding effects for relatively small IPOs. These negative effects appear to be driven by a crowding out of local sector peers, but the crowding out also disrupts local agglomerations and slows down growth among other businesses that rely on local demand. Overall, our results indicate that macroeconomic gains from IPOs trade off against disruptions in local agglomeration economies where public firms originate.

Both market timing and investment-based theories of corporate financing predict under-performance after firms raise capital, but only market timing predicts that the composition of financing (equity compared with debt) should also forecast returns. In cross-sectional tests, we find that the amount of net financing is more important than its composition in explaining future stock returns. In the time series, investment-based factor models explain abnormal stock performance following a variety of corporate financing events that previous studies link to market timing. At the aggregate level, the amount of new financing is also more important for future market returns than its composition. Overall, our joint tests reveal that measures of real investment are correlated with future returns and measures of managerial market timing are not.
