Existence and Nash implementation of efficient sharing rules for a commonly owned technology 总被引:2,自引:0,他引:2
Suppose that a group of individuals owns collectively a technology which produces a consumption good by means of a (possibly
heterogeneous) input. A sharing rule associates input contributions with a vector of consumptions that are technologically
feasible. We show that the set of allocations obtained by any continuous sharing rule contains Pareto efficient allocations.
We also present a mechanism that implements in Nash equilibrium the Pareto efficient allocations contained in an arbitrary
sharing rule.

We explore to what extent we can propose fixed negotiation rules and simple mechanisms (or protocols) that guarantee that political parties can form stable coalition governments. We analyze the case in which three parties can hold office in the form of two-party coalitions. We define a family of weighted rules that select political agreements as a function of the bliss points of the parties and electoral results (Gamson’s law and equal share among others are included). We show that every weighted rule yields a stable coalition. We use implementation theory to design a protocol (in the form of a mechanism) that guarantees that a stable coalition will govern. We find that no dominant solvable mechanism can be used for this purpose, but there is a simultaneous unanimity mechanism that implements it in Nash and strong Nash equilibrium. Finally, we analyze the case of a larger number of political parties. 相似文献

Plurality rule is mostly criticized from being capable of choosing an alternative considered as worst by a strict majority.
This paper considers elections in which the agenda consists of potential candidates strategically choosing whether or not
to enter the election. In this context, we examine the ability of scoring rules to fulfil the Condorcet criterion. We show
for the case of three potential candidates that Plurality rule is the only scoring rule that satisfies a version of the Condorcet
criterion in two cases: 1) when preferences are single-peaked and, 2) when preferences are single-dipped.

The effects of childbearing and work sector on women's hours and earnings in the 8 years following an index pregnancy were
examined in a cohort of more than 2,000 women in the Cebu Longitudinal Health and Nutrition Survey. Change in cash earnings
and hours worked were each modeled jointly with sector of labor force participation using an estimation strategy that deals
with endogeneity of childbearing decisions and selectivity into sector of work. Two or more additional children born in the
8 year interval significantly reduced women's earnings, while having an additional child under 2 years of age in 1991 reduced
hours worked.

A simple procedure to tighten the Lagrangian bounds is proposed. The approach is interpreted in two ways. First, it can be
seen as a reformulation of the original problem aimed to split the resulting Lagrangian problem into two subproblems. Second,
it can be considered as a search for a tighter estimation of the penalty term arising in the Lagrangian problem. The new bounds
are illustrated by a small example and studied numerically for a class of the generalized assignment problems. 相似文献

In the citizen–candidate approach each citizen chooses whether or not to run as candidate. In a single-peaked preference domain,
we find that the strategic entry decision of the candidates eliminates one of the most undesirable properties of Plurality
rule, namely to elect a poor candidate in three-candidate elections since as we show, the Condorcet winner among the self-declared
candidates is always elected. We find that the equilibria with three candidates are basically 2-fold, either there are two
right-wing candidates and a left-wing candidate who wins the elections (or its symmetric), or there is a right-wing candidate,
a left-wing candidate, and a candidate located in between the two others who becomes winner. We also show that when four or
more candidates enter the contest, Plurality rule can elect the Condorcet-loser among the self-declared candidates.

Public infrastructure investment is usually co-financed by supranational organizations. The selection of projects is supposed
to be decided using the information provided by conventional cost-benefit analysis. Nevertheless, we show that the type of
institutional design regarding the financing mechanism affects the incentives of national governments to reduce costs and
increase revenues, affecting project selection, the infrastructure capacity, the choice of technology, and the type of contract
used for the construction and operation of projects. With a total cost-plus financing mechanism there is no incentive in being
efficient and the price charged for the use of the new infrastructure is zero, the market quantity excessive, and the level
of supranational financing disproportionate. In contrast, with a sunk cost-plus financing mechanism social optimal pricing
is always implemented, though there is no incentive in being efficient. Finally, with a fixed-price financing mechanism the
maximal efficiency may be achieved, and the socially optimal pricing is always implemented. 相似文献

In this paper, an exploratory content analysis has been developed for a case study on the topic of immigration reported in the regional newspapers of the largest Spanish autonomous community, Castilla and Leon. This study based its research conceptualization on the framing theory in mass communication. In addition to usual issue frames and issue images, two framing devices were established for analytic variables ‐‐ the index of importance and the index of affective attribute. They formed a frame package capable of making latent frames evident by their linkage to manifest frames. Comparing to the general assumption of relevant‐bad‐news production, results obtained in this study proved that, on occasion, negative news stories could be reported as less relevant than the positive ones. The outcomes also show how concept mapping of frames was applicable to immigration issues and immigrants’ visual aspects of immigrant communities that were systematically articulated and disseminated by the press in this regional society of Spain. 相似文献
