Nationalekonomiska metoder och modeller tillämpas inom de mest skiftande områden som kriminalitet, barnuppfostran och drogmissbruk. Ett skäl till ämnets framgång är dess användning av matematik. Nationalekonomins formalisering synes dock även ha inneburit insnävade beteendeantaganden...

In this paper we first critically review conventional environmental economics. We conclude that the standard theory offers too narrow a perspective for many real world problems and that many theories are not empirically tested. Consequently, environmental economics is at risk of producing...

This paper revisits old questions of the proper subject and bounds of economics: Does economics study “provisioning”? or markets? or a method of reasoning, self-interested rational optimization? A variety of scholars and others in many fields make use of a taxonomy of society consisting of...

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...

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...

Nach einem kurzen Rückblick auf das Downs-Modell diskutieren wir anhand empirischer Daten aus Deutschland dessen heutige Relevanz unter Berücksichtigung der aus der Fairness-Literatur bekannten Ungleichheitsaversion (UA). Dabei wird der Begriff der sozialen Präferenzen um das neue Konzept der...

We use a natural field experiment to investigate the hypothesis that generosity is partly involuntary, by examining whether individuals tend to avoid opportunities to act generously. In Sweden, new recycling machines for bottles and cans with an option of donating the returned deposit to charity...

We model self-control conflict as a stochastic struggle of an agent against a visceral influence, which impels the agent to act sub-optimally. The agent holds costly pre-commitment technology to avoid the conflict altogether and may decide whether to procure pre-commitment or to confront the...
