IMPACTS OF ADVERTISING, ATTITUDES, LIFESTYLES, AND HEALTH ON THE DEMAND FOR U.S. PORK: A MICRO-LEVEL ANALYSIS

Using datat from the 1994-1996 CSFII/DHKS, we identify and assess factors affecting the decision to consume pork and conditional on consuming pork, the decision of the amount of pork intake. Branded and generic advertising of pork play a prominent role in both decisions. Beef advertising, however, does not significantly affect either the probability of consuming pork or the amount of pork intake. Key health, attitudinal and lifestyle factors are smoking status, dietary status, body mass index, the importance of nutrition in buying food, and trimming visible fat from meat. These factors however impact the probability of consuming pork rather than the amount of pork consumed. Region, urbanization, race, age, income, and seasonality also affect pork demand.branded advertising and promotion, CSFII/DHKS (1994-96), generic advertising and promotion, pork demand, pork checkoff, Demand and Price Analysis, Marketing,

Material parameter determination from scattering measurements

The electrical, macroscopic performance of isotropic material can generally be described through their constitutive scalar parameters, permittivity and permeability which are symbolically represented by epsilon and mu, respectively. These parameters relate the electric and magnetic flux densities to the electric and magnetic fields through the following relationships: (1) D=epsilonE; and (2) B=muH. It is through these parameters that the interaction of electromagnetic waves with material can be quantized in terms of reflection and transmission coefficients, and propagation and attenuation factors

Quantile autoregressive distributed lag model with an application to house price returns

This paper studies quantile regression in an autoregressive dynamic framework with exogenous stationary covariates. Hence, we develop a quantile autoregressive distributed lag model (QADL). We show that these estimators are consistent and asymptotically normal. Inference based on Wald and Kolmogorov-Smirnov tests for general linear restrictions is proposed. An extensive Monte Carlo simulation is conducted to evaluate the properties of the estimators. We demonstrate the potential of the QADL model with an application to house price returns in the United Kingdom. The results show that house price returns present a heterogeneous autoregressive behavior across the quantiles. The real GDP growth and interest rates also have an asymmetric impact on house prices variations

REVISITING ENGEL'S LAW: EXAMINING EXPENDITURE PATTERNS FOR FOOD AT HOME AND AWAY FROM HOME

Expenditure patterns were examined for food partitioned into food at home and away from home to test the veracity of Engel's law. The analysis employed several functional forms and a Heckman two-step methodology to account for censored-response bias. Engel's law was verified in every case.Consumer/Household Economics,
