This research compared bids that consumers placed on non genetically modified (GM), organic, and conventional versions of food products in order to determine if the organic market well serves those seeking to avoid GM foods. Auction experiments using potato chips, tortilla chips, and milk chocolate were conducted with 79 subjects. Bids were modeled as a function of consumer demographics using a heteroskedastic tobit regression model. Results with the non-GM attribute nested into the organic characteristic showed that the latter's marginal effects were insignificant. This suggested the potentia

This paper presents the analysis of technical efficiency of cowpea farmers in Osun State Southwest Nigeria, using the stochastic production frontier. The farmers’ average technical efficiency is 87%, which suggest an appreciable use of inputs in productivity. Analysis of technical efficient and some socio-economic variables using tobit regression model is found to be significantly different from zero at 1% for cooperative membership and farming experience. These are farm size, seed, hired labour, family labour, fertilizer and pesticides. It is suggested that farmers should be encouraged to joi

At first the tobit models according to T. Amemiya’s classification ([1]) are presented in the paper. Next, expected values and marginal effects in these models are obtained. In the tobit models marginal effects are not equal to coefficients of the model in general. To get a proper interpretation in the considered models, it is necessary to obtain marginal effects as a partial deviation of the expected values. Moreover, marginal effects are different for binary and continuous variables.

Background: When calculating the decreases in health utility associated with adverse events, often a number ofrespondents achieve the upper utility bound of 1. “Marginal” Tobit or CLAD coefficients have been used to account for this. These are calculated by using a Tobit or a CLAD model to estimate the decrease in a latent unbounded variable associated with the event or condition, then to multiply by the proportion of respondents falling below 1 in order to transform back to the utility scale. Objective & Methods: Starting with the Tobit model, we show mathematically that this procedure is

The Tobit model, also known as a censored regression model to account for left- and/or right-censoring in the dependent variable, has been used in many areas of applications, including dental health, medical research and economics. The reported Tobit model coefficient allows estimation and inference of an exposure effect on the latent dependent variable. However, this model does not directly provide overall exposure effects estimation on the original outcome scale. We propose a direct-marginalization approach using a reparameterized link function to model exposure and covariate effects directl

At present, the e-commerce industry of agricultural products plays a pivotal role in promoting income growth and helping rural revitalization. This paper collected relevant data in the recent 8 years (2012 to 2019) and used the DEA model and Tobit model to analyze the correlation degree between the efficiency and various influencing factors in China. DEA analysis results show that, in recent years, three efficiencies are quite different: the comprehensive efficiency and scale efficiency show an upward trend, while the pure technical efficiency remains at a high level.

Our results indicate that the sector is cost-inefficient, with an average score of 58 percent – an outcome of the inappropriate use of inputs. The Malmquist productivity index performs better, indicating an improvement in total factor productivity of about 3 percent on average.

Abstract This study provides insight into the determinants of timber supply from private forests through development of both theoretical and empirical models of harvest behavior. A microeconomic model encompasses the multiple objective nature of private ownership by examining the harvest decision for landowners who derive utility from forest amenities and from income used for the consumption of other goods. Tobit analysis is used to estimate the relationship between harvest behavior and forest, owner, and economic characteristics from cross-sectional data for individual forest plots in New Ham

This article discusses the implications of four models related to trade, immigration, and cross-border investment. These four models are: Hecksher-Ohlin, Samuelson-Jones and Ricardo-Viner, neo-Ricardian, and Economies of Scale. The first three models assume constant returns to scale, but all models make the conventional assumption of diminishing marginal returns to any individual factor. The article discusses each model in detail, focusing on trade in products and cross-border migration and investment.

Offering increased variety in a market is one method of capturing greater market share. However, we generally observe diminishing marginal returns in share as the size of the product line is increased. Leveraging commonality is a means of offsetting this constraint as it leads to reductions in manufacturing costs and build complexity. Product platforms strive to capitalize on the naturally occurring phenomena that yield commonality in a product line. The structure of design variable values of individually optimized products create opportunities for commonality in a bottom-up platform, while a

This technical paper documents one approach to incorporating monopolistic competition into the GTAP model. In this framework, consumer preferences are heterogeneous, leading to an apparent "love of variety" in the aggregate utility function for each region. The more heterogeneous are preferences, the smaller the elasticity of substitution in the aggregate utility function, and the greater the value placed on the addition of new varieties. The same is true for firms, which experience lower unit costs for differentiated, intermediate inputs, as the number of varieties on offer increases. In orde
