When calling its convertible bonds, a company must typically give bondholders a notice period of about 30 days to decide whether to convert the bonds. This notice period affects the optimal call policy for convertible bonds. After accounting for the notice period, convertible bonds in our sample would have been optimally called when the stock was at about an 11% premium (median) relative to the conversion price. We show that after properly accounting for the call notice period and other factors, the median excess call premium is less than 4%—substantially less than the 26–44% call premium previous researchers have documented.

We use venture-backed initial public offerings (IPOs) to identify and examine the comparative advantage of inexperienced venture capitalists. We argue that, vis-a-vis more established counterparts, younger venture capital firms have a comparative advantage at producing soft information about relatively opaque start-up companies due to their organizational structure. We then quantify an outcome—IPO initial return—from the matching of venture capitalists and start-up companies that demonstrates how this comparative advantage arises. Our findings thus reveal an important aspect of how inexperienced venture capitalists support start-up companies.

Using several different methodologies, we quantify the statistical robustness of variables used in prior research to explain initial IPO returns. We establish a parsimonious list of robust variables and evaluate their implications for different theories of IPO underpricing and clustering. Further, we illustrate how using such a set of robust explanatory variables leads to several different conclusions than prior research that failed to include these important control variables. Researchers who identify new potential predictors of IPO initial returns should control for the list of robust variables we identify.
