Cost Analysis for Water Distribution in Agriculture AgEcon
Dono, Gabriele; Giraldo, Luca.
This paper uses a Translog form to estimate the water distribution cost for an irrigation consortium. The consortium operates under conditions of the under-utilization of facilities; thus, to achieve full cost recovery, water charges must be set at a higher level than efficiency. As a consequence, farmers may decide to reduce their use of the public irrigation service and instead exploit groundwater. The estimated Translog function explains the costs of water services throughout the irrigated area, and identifies items for which pricing does not accentuate the competition between the use of surface water and groundwater. Based on the estimated coefficients, a hypothesis is hence presented for pricing water provided by the consortium.

De Gustibus Asparagus: Habits, Trade, and Welfare from Out of Season Imports of Fresh Vegetables AgEcon
Ferrier, Peyton Michael; Zhen, Chen.
Fresh vegetables, including asparagus, are now available in months outside of the domestic growing season for most U.S. consumers. We use the virtual price method to calculate the equivalent variation for increased availability in a demand system for fresh and frozen vegetables and find that virtual price of out-of-season asparagus is roughly 3 times higher than its in-season price in years prior to year round availability. We find the equivalent variation between 1986-1991 (when asparagus was available approximately half the year) and 1993-1999 (when it was available year round) to be 0.91 of consumer vegetable budgets, implying a welfare benefit of approximately $86 million annually. We also find evidence of habit formation for fresh but not frozen...

Input Substitution in the Spanish Food Industry AgEcon
Alarcón, Silverio.
Firm panel data sets over the period 1993 to 2002 are used to estimate translog production functions with labour, capital and material inputs for 9 Spanish food industries. To tackle the endogeneity of the regressors, the generalized method of moments estimations is employed. The specification tests reject the instrument variables only for 1 out of 9 estimates. The remaining 8 industries show evidence of homogeneity and constant returns to scale. Only one industry exhibits complete separability of all pairs of factors and thus translog is preferred to Cobb-Douglas specification for 7 industries. Substitutability and complementarity between production factors in response to price changes are studied through Morishima and Shadow elasticities....

Productivity and Economic Growth in Tunisian Agriculture: An Empirical Evidence AgEcon
Dhehibi, Boubaker; Lachaal, Lassaad.
This paper analyse the patterns of productivity and economic growth in the Tunisian agriculture during the 1961–2000. Results indicated that agriculture output growth where high in both the 1961–1970 and the 1971–1980 periods but decreased during the 1991–2000 period. Average output growth exceeded 6% during the 1981–1990 period, the average output growth during 1991–2000 had fallen to 4%. Over the whole period, capital was the most important contributor to output growth and labour is considered as the least significant contributor to economic growth. Total factor productivity contribution to output growth decreased from 4.64% in 1961–1970 to 2.86% in 1971–1980. In contrast, this contribution increased in 1981-1990 to close the 4.38%. In the last period,...
