In this paper we use some(even a convex) probabilistic frequency functions in two choice variables defined over the budget set” box” and calculate the expected demand to study its properties The expected demands have own price negativity , are normal goods and are homogeneous of degree...

This paper presents a life cycle model that contains the Beckers (1975) and Heckmans (1976) models as special cases. Contrary to the previous literature, the model can explain the life cycle hypothesis and the maximum in the consumption profile without appealing to the rupture of typical...

In this paper we assume that choice of commodities at the individual (household) level is made in the budget set and that the choice can be described by a probability density function. We prove that negativity (()0xExp<) is valid for one(x) or two choice variables (x, y) (No Giffen good).Negativity at the market level is valid by summation. The expected demand functions are homogeneous of degree zero in prices and income. We use general positive continuous functions f(x), f(x, y) defined on the bounded budget set. We transform them into probability density functions to calculate E(x) and prove negativity. The present approach use simple assumptions and is descriptive in its nature. Any choice behaviour that can be described by a continuous density function gives the above results. (,,)xyppm Why not keep descriptions as simple as possible?<p>

In this paper we assume that choice of commodities at the individual (household) level is made inside the budget set and that the choice can be described by a probability density function. We prove that law of demand()0xExpis valid for one(x) or two choice variables (x, y)*. The law of...

This paper looks at the fuel choice of urban households in major Ethiopian cities, using panel data collected in 2000 and 2004. It examines use of multiple fuels by households in some detail, a topic not much explored in the household fuel-choice literature in general, and in sub-Saharan Africa...

In a split sample design, we examine how the number of choice sets, design of the first choice set (starting point), and the choice of attribute levels in the cost attribute affect the precision in the elicited preferences in otherwise completely identical choice experiment surveys. These issues...

In this paper we investigate consumer preferences for various environmentally-friendly production systems for carrots. We use discrete-choice multi-attribute stated-preference data to explore the effect of the collective reputation of growers from an Alpine valley with an established reputation...

In an effort to improve productivity and profits many farmers have replaced traditional livestock breeds with higher yielding alternatives. While such changes may bring about short-term economic gains, the loss of traditional livestock breeds could result in the loss of an important genetic...

We review the basic principles for the evaluation of design efficiency in discrete choice modelling with a focus on efficiency of WTP estimates from the multinomial logit model. The discussion is developed under the realistic assumption that researchers can plausibly define a prior on the...
