      abstract     = {Large databases mapping commodity flows measured in various
                      units such as currency, tons or caloric values are the
                      backbone of many recent environmental-economic studies.
                      Their construction typically requires combining large
                      amounts of partial information in a series of successive
                      steps. These include the estimation of unobserved flows,
                      transformations between units, handling aggregation
                      re-classification and, finally, reconciling estimates with
                      mass, financial and/or energy balances. This paper proposes
                      a maximum entropy model that allows for the simultaneous
                      estimation of unobserved commodity flows as well as
                      corresponding prices such that data constraints in various
                      units of measurement, levels of aggregation and possibly
                      mismatching classifications are simultaneously satisfied.
                      Its capability is assessed through a Monte-Carlo analysis
                      and its performance compared with a simple step-wise
                      approach. Our results suggest that the simultaneous approach
                      performs significantly better in a vast majority of cases.},
