Reducing Africa's dependence on Asian rice imports requires tailoring local rice products to food markets that are segmented by cultural heritage of ancient rice domestication and colonial heritage of more recent import substitution policies. Using experimental auctions, we examine quality...

We conducted a randomized controlled trial testing the effect of modest incentives to attend the gym among new members of a fitness facility, a population that is already engaged in trying to change a health behavior. Our experiment randomized 836 new members of a private gym into a control...

We reformulate neoclassical consumer choice by focusing on γ, the marginal utility of money. As the opportunity cost of current expenditure, γ is approximated by the slope of the indirect utility function of the continuation. We argue that γ can largely supplant the role of an arbitrary...

In this paper we develop a theoretical model concerning self-control, motivation and commitment. The model, based on Gul and Pesendorfer (2001), studies a two-period decision problem of an agent who faces a given menu and might experience temptation in the second period. In this case, the agent...

The standard continuous-time version of discounted utility does not possess the local inter-temporal substitution property (quantities consumed in nearby dates should be close substitutes, not complements), and hence does not define a continuous functional in the space of consumption paths. The...

In this paper, I propose a simple model in which behavior is determined by the individual's attitude towards the behavior and the attitude depends on the individual's values. The model is based on the Schwartz theory of human values, which is very prominent in social psychology. Values are...

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...

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>

Why do we love stories? That this is not an idle question is shown by the fact that we spend an enormous amount of time in our lives following stories: telling and listening to them; reading them; watching them on television or in films or on stage. Despite their recurrent similarity and even...
