Voluntary donations to non-game species protection through state income tax checkoffs are analyzed. An analogy between the contingent valuation method and check-off scheme is drawn by observing the existence of agenda effects in the latter. Results reveal that substitution and sequencing effects...

Ever since 1927, when Al Jolson spoke in the first “talkie” film The Jazz Singer, there had been little doubt that sound added a valuable perceptual dimension to visual media. However, despite the advances of over 80 years, and the complete integration of sound and vision that has occurred...

Increased attention has recently been given to technical efficiency of small-scale irrigation to achieve food security and increase agricultural development. In this paper, the authors classify irrigation supply management methods as cooperative or non-cooperative, introduce social capital by...

Economic theory provides little guidance for selecting a numeraire in estimating dual function profit functions. In this study, we examine the choice of numeraire price (equation) for profit function models of Iowa agriculture. The choice of numeraire is evaluated by forecasting accuracy and...

Should econometricians always incorporate economic theory in their models or only when unrestricted estimators are found to violate an inviolable theory? Using Monte Carlo experiments, we find that econometricians should use economic theory to the fullest extent possible. To paraphrase Leamer's...

The Induced Innovation Hypothesis (IIH) is tested for Western US agriculture by means of a cointegration test. An ECM model is used to separate the short-run and long-run effects of relative price changes. A difference in the elasticities of factor substitution along the isoquant curve and the...

Consistent aggregation of production data across commodities and states was tested using Lewbel's generalized composite commodity theorem (GCCT). This was the first empirical GCCT test for consistent geographic aggregation and was applied to two groups of states. Consistent commodity aggregation...

We construct a stochastic dual model to investigate the structural adjustment of three aggregate input and two aggregate output categories in U.S. agriculture under climatic change uncertainty. A century of national annual data (1910-2011) is used in the empirical analysis. Independent and...

This article examines factors driving technical change, technical efficiency, and scale and mix efficiency – all components of total factor productivity – in U.S. agriculture. We use economic theory and previous literature to identify explanatory variables affecting each component and...
