Bridging the gap between partial and total factor productivity measures using directional distance functions

Autor: Nin, A. Arndt, C. Hertel, Thomas W. Preckel, P.V.

Technical dependencies as well as data constraints limit our ability to allocate inputs across sectors and hence our ability to measure sectoral productivity. We adapt a directional measure of efficiency to the measurement of sector-specific productivity that does not require allocating all input...

Is agricultural productivity in developing countries really shrinking? New evidence using a modified nonparametric approach

Autor: Nin, A. Arndt, C. Preckel, P.V.

Nonparametric productivity analyses performed to date show that most developing countries are experiencing relatively rapid technical regress in agriculture. We discuss the plausibility of these results and argue that they stem from the existence of biased technical change and the definition of t...

Forest resource depletion, soil dynamics, and agricultural productivity in the tropics

Autor: Ehui, Simeon K. Hertel, T.W. Preckel, P.V.

A two-sector dynamic model for agriculture and forestry is proposed. Agricultural yields are a function of the rate of deforestation, the forest stock, and purchased inputs. We examine the impact of changes in the social discount rate, net returns to agriculture, and direct marginal benefits of t...
