Productivity and profitability, in levels and changes, are measured with various indices. In addition to the classic Malmquist productivity index, the 'productivity' package contains also the multiplicatively complete Fisher, Laspeyres, Paasche, Färe-Primont and Lowe indices. Färe-Primont and Lowe indices verify the transitivity property and can therefore be used for multilateral or multitemporal comparison. Malmquist, Fisher, Laspeyres and Paasche indices not transitive and are only to be used for binary comparison. All indices can also be decomposed into different components providing insightful information on the sources of productivity and profitability improvements. In the use of Malmquist productivity index, the technological change index is further decomposed into bias technological change components. In the case of the Fisher, Laspeyres, Paasche and the transitive Färe-Primont and Lowe indices, it is furthermore possible to rule out technological change. The package also allows to prohibit negative technological change. All the estimations are based on the nonparametric Data Envelopment Analysis (DEA) and several assumptions regarding returns to scale are available (i.e. CRS, VRS, NIRS, NDRS). The package allows parallel computing as an option, depending on the user's computer configuration.
