This paper fills a gap in the macroeconomic literature on renewable sources of energy. It offers a definition of green investment and analyzes the trends and determinants of this investment over the last decade for 35 advanced and emerging countries. We use a new multi-country historical dataset...

This paper discusses structure, impact, costs, and efficiency of renewable energy supply in the eight largest advanced economies (the G-7 plus Spain), with focus on Germany. Renewables production costs are compared to benefits, defined as reductions in net carbon emissions; technological...

Fiscal instruments are potentially among the most effective, and cost-effective, options for addressing externalities related to poor air quality, urban road congestion, and greenhouse gases. This paper takes a case study, focused on Mauritius (a pioneer in the use of green taxes) to illustrate...

This paper calculates, for the top twenty emitting countries, how much pricing of carbon dioxide (CO2) emissions is in their own national interests due to domestic co-benefits (leaving aside the global climate benefits). On average, nationally efficient prices are substantial, $57.5 per ton of...

This paper presents an overview of recent U.S. fiscal developments and discusses possible implications of the sharp turn around in the government’s fiscal position. Against this back ground, it also reviews key policy challenges that will need to be addressed to cope with the mounting...

We derive non-cooperative Nash equilibrium (NE) importer and exporter petroleum excise taxes given full within-group tax coordination, but no coordination between groups, assuming that importers do not produce and exporters do not consume petroleum, and petroleum consumption causes a global...
