Should the choice of numeraire price for modelling profit functions be arbitrary, or is more careful study needed? Here, the choice of numeraire is examined using tests for models specification and out-of-sample predictive accuracy based on the crop and livestock data obtained from Iowa. The...

This article considers two coarse measures applicable to antitrust policy: one of market concentration, the Herfindahl--Hirschman Index (HHI) and one of market dominance, threshold value. Calculations of threshold value are compared to HHI values to determine when thresholds might be of specific...

Expected effects from partially lifting tariff barriers on the Mexican agricultural sector are investigated using a restricted profit function (RPF) approach. Short-run and intermediate-run effects of the implementation of GATT minimum tariff provisions on Mexican agricultural trade are...

Refutable implications based on the curvature properties of the indirect utility function for the competitive firm operating under uncertainty are extended to the case of both price and quantity uncertainty. Using unit roots and cointegration tests for heterogeneous panels, a model of US...

The induced innovation hypothesis is tested for the USA and western regions using cointegration procedures. An error correction model separates short-run and long-run effects of relative price changes. A significant difference in the elasticities of factor substitution along the isoquant and the...

Dynamic effects of health and inter-state and inter-industry knowledge spillovers, Total Factor Productivity (TFP) growth and convergence in US agriculture are examined using recently developed procedures for panel data and a growth accounting model. Strong evidence is found to support the...

Curvature properties of the indirect utility function are shown to be necessary and sufficient for refutable behavioural postulates in the form of comparative static results, reciprocity relations, and restrictions on output and input responses for firm models under risk. These postulates are...

Nonparametric support for two important hypotheses relevant to econometric model specification is examined. Results of various nonparametric tests for behavioural objective and aggregation level of Mexican agricultural production data are reported. The evidence does not refute the hypothesis...

We examine the impact of marketing contracts on farm cost structure and implied scale and scope economies for large samples of dairy, corn and wheat farms. We consider a multi-product, multi-market technology to examine returns from diversifying marketing schemes. Allowing for risk preferences...

Measurement of economies of scale and scope is particularly important for predicting growth and product diversification. However, estimates are useful only to the extent the underlying production technology is modelled accurately. This study measures economies of scale and scope in the rapidly...
