Both sides of mainstream economics will likely claim support in the International Monetary Fund’s latest report, the April 2015 World Economic Outlook—especially chapter 4, on business investment.*
The Keynesians will certainly like the relationship between investment and output—in other words, the idea that private business investment has declined since the start of the economic crisis because aggregate demand has fallen. Even more: they’ll find support in claim that fiscal policy aimed at reducing budget deficits has actually undermined private investment (which is the flip side of the Keynesian crowding-in argument, i.e., the notion that deficit spending doesn’t crowd out private investment, as neoclassical economists claim, but actually spurs or crowds in corporate investment).
The neoclassicals, for their part, will be encouraged by the focus on “business confidence,” that is, the argument that uncertainty (e.g., with respect to government policies) has played a role in discouraging business investment.
In other words, for Keynesians, the problem with insufficient business investment is mostly on the demand side; while for neoclassical economists, it’s mostly on the supply side.
And, true to form, the authors of that section of the report suggest policy changes on both the demand and supply sides:
We conclude that a comprehensive policy effort to expand output is needed to sustainably raise private investment. Fiscal and monetary policies can encourage firms to invest, although such policies are unlikely to fully return restore investment fully to precrisis trends. More public infrastructure investment could also spur demand in the short term, raise supply in the medium term, and thus ‘crowd in’ private investment where conditions are right. And structural reforms, – such as those to strengthen labor force participation, – could improve the outlook for potential output and thus encourage private investment. Finally, to the extent that financial constraints hold back private investment, there is also a role for policies aimed at relieving crisis-related financial constraints, including through tackling debt overhang and cleaning up bank balance sheets.
What no one seems to want to admit—the authors of the report as well as mainstream (both Keynesian and neoclassical) economists—is that private corporations, which got us into this mess in the first place, have failed to get us out of it. They’re the only ones that have benefited from the recovery, as corporate profits have reached record levels, but they haven’t responded by increasing investment. Instead, they’ve been using the profits they’re accumulated to buyback their stock, engage in new mergers and acquisitions, and distribute them to high-level executives and shareholders.
They want us to believe they’re superman. But we know they’ve simply failed—on both the demand and supply sides.
*To be clear, the chart does not indicate actual declines in business investment and output. Rather, it represents percent deviations from forecasts in the year of recessions.
