Combining data-based economic analysis with policy experience


Excessive tax burdens, especially if combined with a complex regulatory system and poorly coordinated institutions, make taxation inefficient, inequitable and ultimately unable to raise sufficient revenue

ECOPA helps tax administrations and funding agencies improve the attractiveness of tax systems and enhance revenue mobilization. 

ECOPA’s expertise in tax analytics includes econometric modeling and micro simulations for tax policy assessment. ECOPA also advises tax authorities on compliance and risk-based audit strategies.  


ECOPA has developed specialized expertise in trade analytics. Its approach, combining state-of-the-art modelling techniques with strong field experience, generates robust and well-researched recommendations on trade-related decisions. 

ECOPA’s projects have involved the deployment of large-scale computable general and partial equilibrium models to assess the impact of regional and bilateral trade agreements. 

Impact assessment

To evaluate the impact of programs and policies in taxation and private sector development, ECOPA implements econometric methods to generate counterfactual scenarios and compare them with observed outcomes.

These tools are combined with qualitative techniques (case studies, focus groups) to provide balanced evaluations with practical lessons on policy and program design.

ECOPA is a member of the Economisti Associati-led consortium for impact assessments of the European Union’s internal tax and customs policies, for the European Commission’s DG TAXUD.
