Executive Summary: Iowa offers several tax incentive programs that have been utilized by biofuel producers. The tax credit programs include the Enterprise Zone Program (EZ), the New Jobs and Income Program (NJIP), the New Capital Investment Program (NCIP), and the High Quality Job Creation...

Germany taxes electricity use since 1999. The government granted reduced rates to energy intensive firms in the industrial sector for addressing potentially adverse effects on firms' competitiveness. Firms that use more electricity than certain thresholds established by legislation, pay reduced...

The German response to the Fukushima nuclear power plant incident was possibly the most significant change of policy towards nuclear power outside Japan, leading to a sudden and very significant shift in the underlying power generation structure in Germany. This provides a very useful natural...

Firms and governments often use moral suasion and economic incentives to influence intrinsic and extrinsic motivations for economic activities. To investigate persistence of such interventions, we randomly assign households to moral suasion and dynamic pricing that stimulate energy conservation...

The process of electricity production, distribution, and consumption represents a complex system with many heterogeneous characteristics. Physical constraints of the electricity, especially the difficulties with its storage, pose specific challenges on the structure of the power network and the...

We introduce a framework to evaluate the welfare effects of residential energy efficiency programs and estimate key parameters using a 100,000-household field experiment. Results generally contradict conventional wisdom: there is no evidence of informational or behavioral market failures,...

Recent years have seen a spike in New Zealand's road death toll, a phenomenon also seen in some other countries such as Australia. This paper analyses the short-run impact of fuel prices on road accident outcomes in New Zealand, including the numbers of road deaths, accidents, and injuries....

This paper provides new empirical evidence of the macroeconomic effects of public investment in developing economies. Using public investment forecast errors to identify unanticipated changes in public investment, the paper finds that increased public investment raises output in the short and...

Many jurisdictions use net metering to record the power exchange between solar photovoltaic panels and the grid, thus valuing home production at the electricity retail rate. However, if over the billing period, production exceeds consumption, the surplus remains freely available for consumption....

This paper provides new evidence of the macroeconomic effects of public investment in advanced economies. Using public investment forecast errors to identify the causal effect of government investment in a sample of 17 OECD economies since 1985 and model simulations, the paper finds that...
