Is Investment in Environmental Quality a Solution to Recessions? Studying the Welfare Effects of Green Animal Spirits

Abstract

Assume that 'green accounting' has been adopted and implemented, does an investment in environmental quality play a role similar to the investment in capital in towing the economy out of a recession? To answer the question, we integrate 'green accounting' into a stochastic dynamic general equilibrium model to study the short-run consequences of investment in environmental quality and hereby addressing if there is an incentive-based fiscal environmental solution to recessions. Surprisingly and counter intuitive, we found that reducing the rate at which humans consume the environment renders a fiscal policy - that engage in environmental investment - less effective in providing a thrust out of a recession. Conditional on the proposed model and the calibrated parameters, we conclude that an increase of one percent in environmental investment will crowd out real quarterly consumption in a range from $102.74 billions to$ 171.11 billions, on average, in every quarter for seven years following the investment (measured in chained 2000 dollars). Therefore, we argue that investment in environmental quality is not a solution to recessions. This result is a striking contrast to the conclusion reached in Weitzman and Löfgren (1997, Journal of Environmental Economics and Management, 32 (2), 139-153).Environmental Quality, Green Accounting, Stochastic Dynamic General Equilibrium models
