Projecting Expenditure Baselines in Barcelona


Posted by Jordi Baños-Rovira[1]

In recent years, Barcelona City Council has introduced a range of budget reforms to improve the efficiency of resource allocation and operational management[2]. In particular, a performance-based budgeting system (called the “Executive Budget’) has been developed, linked to the goals set in the Government’s Development Plan[3].

A key element of this new budget preparation process is the development of baseline projections of expenditure, which estimate the spending required to maintain current policies (or levels of service) for the next year, and to comply with already approved multi-year commitments. Budget requests by departments thus comprise two elements: the spending baselines, and additional resources required to finance new projects and services, and other policy changes.

The Barcelona City Council developed its own approach to estimating expenditure baselines, taking account of the existing literature and the experience of other governments. The main benefits of baseline projections[4] are to reinforce fiscal discipline, facilitate an assessment of the sustainability of current policies, provide a neutral base for analyzing and evaluating policy changes, and improve the presentation of the budget to the general public and other stakeholders.

The approach followed in Barcelona focuses mainly on current spending (goods and services and current transfers), looks one year ahead, and makes projections at the highest level of line-item detail. The calculations are performed by line departments (under the guidance and control of the central budget office).

The expenditure baseline projection is one of the first stages of the budget preparation process, usually performed during the months of April and May, and is separated from the budget requests process (which usually takes place between June and September each year). The process is summarized in the chart below. (click the chart for enhanced view)


After line departments have prepared their baseline projections, the central budget office carries out a review of the estimates, in order to evaluate the quality of the data, and whether departments have complied with the procedures and instructions issued by the budget office.

Based on the early experience of applying the new approach, the following important lessons can be drawn:

To sum up, expenditure baseline projections prepared by the Barcelona City Council have become an important tool for formulating the budget and taking budget decisions. The information helps to determine the amount of fiscal space available to finance new policies, and to explain the budget proposals to citizens. Further progress can be made, however, to develop and refine the procedures so that that quality and accuracy of the information improves year by year.
