CAMBRIDGE – Economic trends are sometimes more closely related to one another than news reports make them seem. For example, one regularly encounters reports of governments’ financial troubles, like the “fiscal cliff” in the United States and the debt crisis in Europe. And much attention has been devoted, often in nearby opinion pieces, to the view that hyperactive equities markets, particularly in the US and the United Kingdom, push large corporations to focus disproportionately on short-term financial results at the expense of long-term investments in their countries’ economies.
The two are not unconnected. And examining that connection provides a good opportunity to assess the weaknesses and ambiguities of the longstanding argument that furiously high-volume stock-market trading shortens corporate time horizons.
