ABSTRACT
A premise that is widely shared among analysts, irrespective of their methodological or ideological proclivities, is that effective policy responses to “global issues” concerning the human environment require that the time horizon of policy making be expanded (Dahlberg 1983). This is so for the obvious reason that the effects of decisions taken or foregone today may not materialize until well into the future, and it may take equally long to reverse these effects should that prove necessary.
