Scientific Output

Alejandro Caparrós, PhD in Economics, is Senior Researcher at the Institute for Public Goods and Policies (IPP) of the Spanish National Research Council (CSIC), and lecturer at the University Carlos III in Madrid. He was previously Director of IPP, post-doc at the CNRS in Paris and lecturer at the University Paris Est. He has been visiting scholar at the Universities of Berkeley, Columbia, Paris II, Paris Est, Bordeaux, Göttingen, Exeter, Bath and Innsbruck. He has participated in a large number of research projects funded by the European Commission and national agencies, and has worked as consultant for the World Bank and local entities. He currently serves as Lead Author of the chapter on International Cooperation for the WGIII Sixth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC).


Alejandro Caparros’s research focuses on the micro-economic analysis of environmental public goods. His current research deals with two topics:

Incentives for cooperation and international negotiations on climate change

The goal is to analyze incentives for cooperation for different types of public goods, and to determine the negotiation procedures that are more likely to be successful. Alejandro Caparros’s research has analyzed this issue from a purely theoretical point of view and from an applied perspective, by analyzing international negotiations on climate change mitigation. Analyzing actual negotiations allows extending theoretical models to issues not covered by standard models, while it also allows identifying key features of the environmental problem that might explain the difficulties observed in reaching ambitious agreements. The main tool used in these papers is game theory and, in particular, multilateral bargaining theory.

Ecosystem accounting and the aggregation of stated contributions to public goods

This research line focuses on the aggregation of stated contributions to public goods and, in particular, on its use in spatial ecosystem accounting. The goal is to value environmental public goods in a manner consistent with the values recorded in national accounts for commercial goods and services. The procedure proposed is the Simulated Exchange Value method, which simulates the entire market: demand obtained from stated preference methods, cost estimates and market structure. The values obtained are then recorded in an integrated ecosystem accounting system, which has been developed together with other researchers at IPP-CSIC.  The methods proposed have been applied at different scales focusing on terrestrial ecosystems.

Other topics

Over the years, Alejandro Caparrós has also contributed to other issues, such as pollution control, environmental valuation or the analysis of potential conflicts between carbon sequestration by forests and biodiversity conservation. Although they do not fit within the two topics presented above, they are closely related:
