Evaluating the efficiency of museums using multiple outputs: evidence from a regional system of museums in Spain

Data Envelopment Analysis is used to evaluate museum efficiency. This approach enables us to create a relative efficiency measure for each museum, taking into account resources used by museums and the performance of their activities based on four well-defined tasks: conservation, research, communication and exhibition. Empirical analysis of data from a regional museum system in Spain is performed, considering a complex production function with several inputs and outputs. The main findings indicate that at least half the museums chosen operate efficiently, with the major cause for inefficiency being inadequate resource management. Only few museums evidenced significant inadequate scaling problems. Major progress, mainly due to improvements in internal efficiency, is evident in the museum system ratios when analysing productivity evolution using the Malmquist Index. By contrast, technological change has less impact, proving that cultural heritage is less receptive to new technologies as compared to other cultural industries.
