Many econometric analyses include dependent variables constrained to the interval between zero and 1 Under such conditions, simple regression procedures break down Several alternative stochastic models which avoid this problem can be defined depending on the assumed error structure Two...

A particular numerical analytical technique for solving systems of simultaneous equations which offers several advantages to the user over other numerical techniques is discussed. The Gauss-Seidel algorithm is simply an iterative technique which requires no derivatives, matrix inversion,...

The aggregate economic indicators and statistical series published by the U S Department of Agriculture provide insufficient Information for decisionmakers requesting disaggregated analyses of farm industries, farm types, or farm Sizes However, this Information can be obtained through the annual...

A recently published model of the livestock-meat economy is used to illustrate modifications that permit us to obtain a reasonable and consistent set of projected values to 1980. Ecollomic theory and an understanding of the industry were used to introduce a set of assumptions about institutional...

When using input-output analysis to measure the effect of exogenous changes in the value of final demand, it is important to identify the degree to which the change in value is due to changes in prices or to changes in the volume of demand. A modified input-output model is presented to...

A nonlinear production function can cause gambling or insuring in a risk situation. This result holds independently of the shape of the utility function for income. When a random variable enters an entrepreneur's production function with diminishing returns, profit maximization behavior can be...

The validity of the assumptions underlying the 21-Meal-Nutritionally-EquivalentPerson (21-MNEP), an adjustment procedure employed In nutritional analyses of U S Department of Agriculture food consumption survey data, IS examined Some assumptions are inconsistent With actual nutrient Intake data...

Grafting an adjustment equation onto an input-output based projection model improves the predictive performance of the unadjusted model and results in a relatively sensitive estimator of both the level of and changes in nominal and real gross farm product.

If data series are not filtered properly prior to the construction of a test of causality, the resulting test statistics are invalid This article,describes a general approach to data filtering based on the estimation of autoregressive-moving-average models and on specific tests for the...

A 14 equation recursive model is developed for (1) flue-cured acreage, (2) burley acreage, (3) flue-cured price, (4) burley price, and (5) consumer demand for cigarettes. The coefficients are estimated using data for 1954-70. The reduced form and the impact multipliers are derived. The...
