Go West Young Man: Self-selection and Endogenous Property Rights

If, as Hume argues, property is a self-referring custom of a group of people, then property rights depend on how that group forms and orders itself. In this paper we investigate how people construct a convention for property in an experiment in which groups of self-selected individuals can migrate between three geographically separate regions. We find that the absence of property rights clearly decreases wealth in our environment and that interest in establishing property rights is a key determinant of the decision to migrate to a new region. Theft is nearly eliminated among migrants, resulting in strong growth, and non-migrants remain in poverty. Thus, self-selection, through the decision to migrate, to form more cooperative groups is essential for establishing property rights.experimental economics, property rights, migration and exit

Self-sterilization of bodies during outer planet entry

A body encountering the atmosphere of an outer planet is subjected to heat loads which could result in high temperature conditions that render terrestrial organisms on or within the body nonviable. To determine whether an irregularly shaped entering body, consisting of several different materials, would be sterilized during inadvertent entry at high velocity, the thermal response of a typical outer planet spacecraft instrument was studied. The results indicate that the Teflon insulated cable and electronic circuit boards may not experience sterilizing temperatures during a Jupiter, Saturn, or Titan entry. Another conclusion of the study is that small plastic particles entering Saturn from outer space have wider survival corridors than do those at Jupiter

The Ecological and Civil Mainsprings of Property: An Experimental Economic History of Whalers’ Rules of Capture

This paper uses a laboratory experiment to probe the proposition that property emerges anarchically out of social custom. We test the hypothesis that whalers in the 18th and 19th century developed rules of conduct that minimized the sum of the transaction and production costs of capturing their prey, the primary implication being that different ecological conditions lead to different rules of capture. Holding everything else constant, we find that simply imposing two different types of prey is insufficient to observe two different rules of capture. Another factor is essential, namely that the members of the community are civil-minded.property rights, endogenous rules, whaling, experimental economics

Go West Young Man: Self-Selection and Endogenous Property Rights

If, as Hume argues, property is a self-referring custom of a group of people, then property rights depend on how that group forms and orders itself. In this article we investigate how people construct a convention for property in an experiment in which groups of self-selected individuals can migrate between three geographically separate regions. To test a hypothesis of Demsetz\u27s, we vary across two treatments the external benefits of migrating. We find that self-selection has a powerful effect on establishing conventions of property and begetting increases in wealth through exchange and specialization. We also find support for the Demsetz hypothesis

Another factor is essential, namely, as Samuel Pufendorf theorized over 300 years ago, that the members of the community are civil minded

Mixing and recirculation characteristics of gas-liquid Taylor flow in microreactors

The effects of operating parameters (capillary and Reynolds numbers) and microchannel aspect ratio (α = w/h = [1; 2.5; 4]) on the recirculation characteristics of the liquid slug in gas-liquid Taylor flow in microchannels have been investigated using 3-dimensional VOF simulations. The results show a decrease in the recirculation volume in the slug and an increase in recirculation time with increasing capillary number, which is in good agreement with previous results obtained in circular and square geometries (Thulasidas et al., 1997). In addition, increasing the aspect ratio of the channel leads to a slight decrease in recirculating volumes but also a significant increase in recirculation times

Beyond sarcasm: the metalanguage and structures of mock politeness

This paper aims to cast light on the somewhat neglected area of mock politeness. The principle objectives are to describe the ways that mock politeness is talked about and performed. In order to investigate such usage, I analyse data from informal, naturally occurring conversations in a UK-based online forum. The paper introduces a range of metalinguistic expressions which are used to refer to mock polite behaviours in lay interactions and describes the different structures of mock polite behaviours. The analysis shows that both metalanguage and structure are more diverse than anticipated by previous research and, as a result, the paper argues against equating mock politeness with sarcasm and calls for further research into mock politeness as an important strategy of impoliteness

Market orientation and SNS adoption for marketing purposes in hospitality microenterprises

ABSTRACT: In a nowadays context where the social network sites (SNS) have a widespread use among users and enterprises, this paper aims to analyze the factors determining the adoption of SNS for marketing purposes by hospitality microenterprises. With this objective, our study develops a model that includes: 1) the two pillars of market orientation for companies (i.e. consumer orientation and competitor orientation); and 2) the factors of the widely used Unified Theory of Acceptance and Use of Technology (UTAUT): performance expectancy, effort expectancy, social influence, and facilitating conditions. The results from a sample of 200 hospitality microenterprises in a region of Spain show that the intention to use SNS for marketing purposes (in particular, business communication) is mainly determined by the expectancies of managers or owners about theperformance and effort in the use of the technology, and by the social influence generated by users and professionals in the sector. Additionally, in contrast to competitor orientation, customer orientation has a positive influence on performance expectancy and social influence
