Conclusions
Constraints to public intervention may have a significant impact on policy cost-effectiveness Qualitative estimations of constraints to public intervention only concern constraints to reach the environmental objective (administration costs, costs of public funds, private costs of compliance) Costs induced by information asymmetry or regulator’s motivations may be included in transaction costs estimates but are difficult to isolate Assessment methods give an idea on the scope of costs but show clear limits to compare and interpret results (no data homogeneity) Conclusions on public policies’ efficiency must be balanced with other policy costs and pollution abatement level
Estimation of constraints to public intervention for a better policy choice. Literature overview
Introduction
From the 1970’s, economists have assessed government failures or specific constraints to public intervention with different terminologies (i.e: public intervention costs, transaction costs, marginal costs of public funds,…) and under different aspects (i.e: information asymmetry between principal and agents, lack of motivation of the regulator to maximize collective well-being, administrative costs of policy implementation and monitoring, distortions on other markets due to the tax system,…). However, most empirical studies are rather recent on the ex-post estimation of these constraints. Given the scope of these constraints and the increasing use of economic instruments and analysis to guide environmental policy decisions, there is a need to reconsider the conditions under which public policy options are likely to be effective. Constraints estimation can improve the comparison of policy alternatives ex-ante. Objective
Based on microeconomic theory and 8 recent ex-post studies, this literature survey aimed at identifying a typology of constraints to public intervention as well as the assessment methods used.

Conceptual model
Agenda setting(objectives of policies)
Policy formulation(policy measures)
Policy implementation(control, enforcement)
Policy evaluationoutcomes (effects on target groups) and impacts (effects on the environment)
Constraints to reach the environmental objective:
- Costs for the regulator (administrative costs, transaction costs)- Costs for regulated agents (private costs of compliance)- Costs for the rest of the society (social costs of public funds)
Constraints to define the environmental objective:- Information on costs and damages- Regulator's motivations- Individual preferences aggregation
Choosing the optimum as environmental policy objective corresponds to fixing the level of externality production through economic calculus. Given the constraints to define this optimum, economic analysis generally focuses on the least-cost methods to reach a defined environmental objective.
Constraint Policy Constraint estimates Method
Markets for water rights 3-29% of average trade price 6% of price paid to transfer water
Management accounting
Water supply
Statistically significant relationship between proxies (population size and variability, water quality) and the contractual arrangement chosen
Statistical method
Pollution abatement and agri-environmental
policies
$ 0.9-9.4 million (for 4 policy scenarios with same environmental objective) 6-87% of compensatory payments (or 1-100% of total scheme costs over a year) 0.1-66% of payment to farmers or tax revenue
Management accounting
Transaction costs, administration costs
Nature conservation 38% of overall conservation costs Management accounting
Costs of public funds
Public policies Social marginal costs of public funds = 1.2 (20% of the taxes collected)
Fiscal data
Categories of methods identified:Management accounting: monetization of staff time inputs to realize administration tasks
(interviews), recording of administrative expenditures (financial and water price data, administration and legal fees ) Statistical method: statistical analysis of the relationship between data on proxies characterizing the constraints and the organization chosen
Fiscal data: estimation of the cost for the community of taxes collected by the State based on households welfare loss
