Internal capital markets (ICMs) provide firms an alternative to costly external financing; however, they also provide an avenue to avoid the monitoring associated with issuing external capital. We argue that firms operating inefficient internal capital markets will avoid outside financing. Consistent with this view, conglomerates that cross-subsidize divisions or engage in value-destroying investment avoid external capital market oversight by refraining from issuing both debt and equity. We further show that firms issuing bonds while engaging in value-destroying investment experience yield spreads that are, on average, 46 basis points higher than those of other diversified firms. They similarly experience yield spreads that are 18 basis points higher when they issue syndicated loans. Value-destroying conglomerates also witness SEO announcement returns that are, on average, 1% more negative than firms operating more efficient internal capital markets.

Using transactions generally overlooked in the compensation literature—joint ventures, strategic alliances, seasoned equity offerings (SEOs), and spin-offs—we find that, beyond compensation for increases in firm size or complexity, chief executive officers (CEOs) are rewarded for their deal-making activities. Boards pay CEOs for the core motivation of the deal, as well as for deal volume. We find that compensating for volume instead of core value creation occurs under weak board monitoring and that in deal-making firms, neither CEO turnover nor pay-for-performance responds to underperformance. We introduce an input monitoring explanation for these results: boards compensate for deal volume because of their inability to perfectly monitor outputs.
