Excess Capacity, Marginal q, and Corporate Investment

Published: 03/11/2025   |   DOI: 10.1111/jofi.13439

GUSTAVO GRULLON, DAVID L. IKENBERRY

Theory posits that when managers anticipate excess capacity, average q becomes a biased estimator of marginal q as the potential for underutilizing new capital reduces the marginal benefit of investing. After correcting for this source of measurement error, the explanatory power of Tobin's q substantially improves in time‐series and cross‐sectional regressions as well as in out‐of‐sample tests. These findings, together with a secular erosion in capacity utilization, help explain why corporate investment rates have been declining for decades despite average q increasing significantly. Our analysis indicates that economic rigidities have contributed to the persistent erosion in capacity utilization.

The Long‐Run Negative Drift of Post‐Listing Stock Returns

Published: 12/01/1995   |   DOI: 10.1111/j.1540-6261.1995.tb05188.x

BALA G. DHARAN, DAVID L. IKENBERRY

After firms move trading in their stock to the American or New York Stock Exchanges, stock returns are generally poor. Although many listing firms issue equity around the time of listing, post‐listing performance is not entirely explained by the equity issuance puzzle. Similar to the conclusions regarding other long‐run phenomena, poor post‐listing performance appears related to managers timing their application for listing. Managers of smaller firms, where initial listing requirements may be more binding, tend to apply for listing before a decline in performance. Poor post‐listing performance is not observed in larger firms.


Stock Repurchases in Canada: Performance and Strategic Trading

Published: 12/17/2002   |   DOI: 10.1111/0022-1082.00291

David Ikenberry, Josef Lakonishok, Theo Vermaelen

During the 1980s, U.S. firms announcing stock repurchases earned favorable long‐run returns. Recently, concerns have been raised over the robustness of these findings. This concern comes at a time of explosive growth in repurchase programs. Thus, we study new evidence from the 1990s for 1,060 Canadian repurchase programs. Moreover, because of Canadian law, we can carefully track repurchase activity monthly. Similarly to the situation in the United States, the Canadian stock market discounts the information in repurchase announcements, particularly for value stocks. Completion rates in Canada are sensitive to mispricing. Trades also appear linked to price movements; managers buy more shares when prices fall.
