When is it prudent to invest in environmental quality if the major impact will be a century hence? Will the capital cost of more efficient manufacturing pay off quickly enough to offset the risks in effectiveness and operating cost? Risk and time are the issues. Matt Sobel’s research highlights the interdependence of individual, firm, and societal preferences regarding riskiness and timeliness. Sobel also studies how best to coordinate business operations and finance for greater competitive effectiveness.
