Tipping is a multi-billion-dollar phenomenon that standard economic models find hard to explain. I discuss several aspects of tipping and divide tipping to six different categories: reward-tipping, price- tipping, tipping-in-advance, bribery-tipping, holiday-tipping and gift- tipping, and...

The article presents a theory that I denote “Relative Thinking Theory,” which claims that people consider relative differences and not only absolute differences when making various economics decisions, even in those cases where the rational model dictates that people should consider only...

We investigate the role that self-control problems modeled as time-inconsistent, present-biased preferences and a person's awareness of those problems might play in leading people to develop and maintain harmful addictions. Present-biased preferences create a tendency to over-consume addictive...

Con questo articolo si intende offrire una rassegna critica del dibattito in corso da più di un decennio sul concetto di capitale sociale. Gli studi considerati sono suddivisi in base all’aspetto della struttura sociale cui di volta in volta viene accordata maggiore enfasi. La rassegna si...

Departures from pure self interest in economic experiments have recently inspired models of "social preferences". We conduct experiments on simple two-person and three-person games with binary choices that test these theories more directly than the array of games conventionally considered. Our...

People underappreciate how their own behavior and exogenous factors affect their future utility, and thus exaggerate the degree to which their future preferences resemble their current preferences. We present evidence which demonstrates the prevalence of such projection bias, and develop a...

This work is focused on identifying the relationship an economic system and its policies have with the environment. The biosphere is chosen in particular as object of analysis but this can be extended by means of an ecosystem recursive properties. The common factor involved in the relationship...

Applying Weglorz' models of set theory without the axiom of choice, we investigate Arrow-type social welfare functions for infinite societies with restricted coalition algebras. We show that there is a reasonable, nondictatorial social welfare function satisfying "finite discrimination", if and...

Previous papers on time-inconsistent procrastination assume projects are completed once begun. We develop a model in which a person chooses whether and when to complete each stage of a long-term project. In addition to procrastination in starting a project, a naive person might undertake costly...

This paper presents an insight into the theoretical and empirical literature of Loss Aversion and Endowment Effect. The definition and conceptualisation of both ideas is introduced in order to define a framework for further analysis. Their presence implies a radical change in some of the basic...
