In a repeated-interaction public goods economy, dynamic behavior may affect the efficiency of various mechanisms thought to be efficient in one-shot games. Inspired by results obtained in previous experiments, the current paper proposes a simple best response model in which players’ beliefs are functions of previous strategy profiles. The predictions of the model are found to be highly consiste...

A discrete public good is provided when total contributions exceed the contribution threshold, yet the threshold is often not known with certainty. I show that the relationship between the degree of threshold uncertainty and equilibrium contributions and welfare is not monotonic. For a large class of threshold probability distributions, equilibrium contributions will be higher under increased u...

The best shot game applied to networks is a discrete model of many processes of contribution to local public goods. It generally has a wide multiplicity of equilibria that we refine through stochastic stability. We show that, depending on how we define perturbations – i.e., possible mistakes that agents make – we can obtain very different sets of stochastically stable states. In particular and ...

We study a fundamental conflict in economic decision-making, the trade-off between equality, equity and incentives, in a new experimental game that nests a voluntary contributions mechanism in a broader spectrum of incentive schemes. In a 2x2 design, we let subjects either vote on or exogenously encounter incentive settings while assigned unequal endowments are either task-determined or random....

A total of 514 Shiga toxin-producing Escherichia coli (STEC) isolates from diarrheic and healthy cattle in Spain were characterized in this study. PCR showed that 101 (20%) isolates carried stx1 genes, 278 (54%) possessed stx2 genes, and 135 (26%) possessed both stx1 and stx2. Enterohemolysin (ehxA) and intimin (eae) virulence genes were detected in 326 (63%) and in 151 (29%) of the isolates, r...

This work consists on an analysis of the arguments used by Randall Holcombe to justify inevitability existence a monopoly services defence and security. We understand that his justification is incomplete because definition he uses, regarding need in provision this type, does not fit with Austrian public goods or monopoly. Besides, it take into account historical evidence these competition. Keyw...

An actinomycete strain, H41-59, isolated from sea sediment in a mangrove district, was identified as Streptomyces anandii on the basis of 16S rDNA gene sequence analysis as well as the investigation of its morphological, physiological and biochemical characteristics. Three new ergosterols, ananstreps A-C (1-3), along with ten known ones (4-13), were isolated from the culture broth of this strai...

Abstract We analyze the structure of 15 protocluster forming regions in Milky Way using their 1.3 mm continuum emission maps from ALMA-IMF large program. The analysis clouds is performed delta-variance spectrum technique. calculated spectra display a self-similar regime on small scales as well presence prominent bump larger and whose physical size, Lhub, falls range ≈7000 au to 60000 au. These ...

In a public-good experiment with heterogeneous endowments, we investigate if and how the contribution level as well as the previously observed fair-share rule of equal contributions relative to one’s endowment (Hofmeyr et al., 2007; Keser et al., 2014) may be influenced by minimum-contribution requirements. We consider three different schedules: FixMin, requiring the same absolute contributions...
