Annex A. Methodology

Measuring regulatory performance is challenging, starting with defining what to measure, dealing with confounding factors, attributing outcomes to interventions and coping with the lack of data and information. This chapter describes the methodology developed by the OECD to help regulators address these challenges through a Performance Assessment Framework for Economic Regulators (PAFER), which informs this review. The chapter first presents some of the work conducted by the OECD on measuring regulatory performance. It then describes the key features of the PAFER and presents a typology of performance indicators to measure input, process, output and outcome. It finally provides an overview of the approach and practical steps undertaken for developing this review.

Analytical framework

The analytical framework that informs this review draws on the work conducted by the OECD on measuring regulatory performance and the governance of economic regulators. OECD countries and regulators have recognised the need for measuring regulatory performance. Information on regulatory performance is necessary to better target scarce resources and to improve the overall performance of regulatory policies and regulators. However, measuring regulatory performance can prove challenging. Some of these challenges include:

What to measure: evaluation systems require an assessment of how inputs have influenced outputs and outcomes. In the case of regulatory policy, the inputs can focus on: i) overall programmes intended to promote a systemic improvement of regulatory quality; ii) the application of specific practices intended to improve regulation, or, iii) changes in the design of specific regulations.
Confounding factors: there is a myriad of contingent issues that have an impact on the outcomes in society which regulation is intended to affect. These issues can be as simple as a change in the weather, or as complicated as the last financial crisis. Accordingly, it is difficult to establish a direct causal relationship between the adoption of better regulation practices and specific improvements to the welfare outcomes that are sought in the economy.
Lack of data and information: countries tend to lack data and methodologies to identify whether regulatory practices are being undertaken correctly and what impact these practices may be having on the real economy.

The OECD Framework for Regulatory Policy Evaluation starts addressing these challenges through an input-process-output-outcome logic, which breaks down the regulatory process into a sequence of discrete steps. The input-process-output-outcome logic is flexible and can be applied both to evaluate practices to improve regulatory policy in general, and also to evaluate regulatory policy in specific sectors, based on the identification of relevant strategic objectives. It can be tailored to economic regulators by taking into consideration the conditions that support the performance of economic regulators (Box A A.1).

The OECD Best Practice Principles for Regulatory Policy: The Governance of Regulators (OECD, 2014b) identifies some of the conditions that support the performance of economic regulators. They recognise the importance of assessing how a regulator is directed, controlled, resourced and held to account, in order to improve the overall effectiveness of regulators and promote growth and investment, including by supporting competition. Moreover, they acknowledge the positive impact of the regulator’s own internal process on outcomes (i.e. how the regulator manages resources and what processes the regulator puts in place to regulate a given sector or market) (Figure A ‎A.1).

Box A ‎A.1. The input-process-output-outcome logic sequence

Step I. Input: indicators include for example the budget and staff of the regulatory oversight body.
Step II. Process: indicators assess whether formal requirements for good regulatory practices are in place. This includes requirements for objective setting, consultation, evidence-based analysis, administrative simplification, risk assessments and aligning regulatory changes internationally.
Step III. Output: indicators provide information on whether the good regulatory practices have actually been implemented.
Step IV. Impact of design on outcome (also referred to as intermediate outcome): indicators assess whether good regulatory practices contributed to an improvement in the quality of regulations. It therefore attempts to make a causal link between the design of regulatory policy and outcomes.
Step V. Strategic outcomes: indicators assess whether the desired outcomes of regulatory policy have been achieved, both in terms of regulatory quality and in terms of regulatory outcomes.

The two frameworks are brought together into a Performance Assessment Framework for Economic Regulators that structures the drivers of performance along the input-process-output-outcome framework (Table A ‎A.1).

Performance indicators

For regulators, performance indicators need to fit the purpose of performance assessment, which is a systematic, analytical evaluation of the regulator’s activities, with the purpose of seeking reliability and usability of the regulator’s activities. Performance assessment is neither an audit, which judges how employees and managers complete their mission, nor a control, which puts emphasis on compliance with standards (OECD, 2004).

Accordingly, performance indicators need to assess the efficient and effective use of a regulator’s inputs, the quality of regulatory processes, and identify outputs and some direct outcomes that can be attributed to the regulator’s interventions. Wider outcomes should serve as a “watchtower”, which provides the information the regulator can use to identify problem areas, orient decisions and identify priorities (Figure A ‎A.2).

Approach

The analytical framework presented above informed the data collection and the analysis presented in the report. The present report looks at the internal and external governance arrangements of the Irish Commission for Regulation of Utilities (CRU) in the following areas:

Strategic objectives: to identify the existence of a set of clearly identified objectives, targets, or goals that are aligned with the regulator’s functions and powers, which can inform the development of actionable performance indicators;
Input: to determine the extent to which the regulator’s funding and staffing are aligned with the regulator’s objectives, targets or goals, and the regulator’s ability to manage financial and human resources autonomously and effectively;
Process: to assess the extent to which processes and the organisational management support the regulator’s performance;
Output and outcome: to identify the existence of a systematic assessment of the performance of the regulated entities, the impact of the regulator’s decisions and activities, and the extent to which these measurements are used appropriately.

Data informing the analysis presented in the report was collected via a desk review, a fact-finding mission and a peer mission to Ireland:

Questionnaire and desk review: the CRU completed a detailed questionnaire which informed a desk review by the OECD Secretariat. The Secretariat reviewed existing legislation and CRU documents to collect information on the de jure functioning of the regulator, and to inform the basis of the fact-finding mission. This questionnaire was tailored to the CRU, based on the methodology already applied by the OECD to Colombia’s Communications Regulation commission (OECD, 2015a), Latvia’s Public Utilities Commission (OECD, 2016b), and Mexico’s three energy regulators (OECD, 2017a; 2017b; 2017c; 2017d).
Fact-finding mission: the mission was conducted by the OECD Secretariat on 15-18 May 2017 in Dublin and was the key tool to collect and complete the de jure information obtained through the questionnaire with the de facto state of play. The work of the fact-finding mission tailored the PAFER methodology to CRU features. Information collected in May 2017 was completed and checked with the CRU for accuracy, and issues for further discussion were also flagged.
Peer mission: the mission took place on 27-30 June 2017 in Dublin and included peer reviewers in addition to OECD Secretariat. This mission met with key stakeholders in the CRU as well as externally. At the end of the mission, the team discussed preliminary findings and recommendations with the CRU’s management, in order to test their feasibility and goodness of fit.

During the fact-finding and peer missions, the team met with CRU’s leadership team as well as a number of staff from across the institution, other government institutions and external stakeholders, including:

Department of Communications, Climate Change and Environment (DCCAE)
Department of Housing, Planning and Local Government (DHPLG)
Department of Public Expenditure and Reform (DPER)
Joint Oireachtas Committee on Housing, Planning and Local Government (HPCLG)
Joint Oireachtas Committee on Communications, Climate Action and Environment
Joint Oireachtas Committee on the Future Funding of Domestic Water Services (disbanded as of April 2017)
Department of the Taoiseach
The independent member of the Single Electricity Market Committee (SEMC)
Environmental Protection Agency (EPA)
Public Water Forum
EirGrid
ESB Networks
Ervia
Competition and Consumer Protection Commission (CCPC)
Electricity Association of Ireland (EAI)
