Productive Efficiency of the Swine Industry in Hawaii: Stochastic Frontier vs. Data Envelopment Analysis

Improving productive efficiency is an increasingly important determinant of the future of the swine industry in Hawaii. This paper examines the productive efficiency of a sample of swine producers in Hawaii by estimating a stochastic frontier production function and the constant returns to scale (CRS) and variable returns to scale (VRS) output-oriented DEA models. The technical efficiency estimates obtained from the two frontier techniques are compared. The scale properties are also examined under the two approaches. The industry's potential for increasing production through improved efficiency is also discussed.     

Linkage Measures: a Revisit and a Suggested Alternative

This paper examines major linkage measures in the literature from different perspectives and attempts to clarify some of the controversies over them. The examination and clarification suggest more refined backward and forward linkage measures for linkage indices construction. The measures are then applied to analyse the linkages of Hawaii’s agriculture sectors.
