Groves Mechanism vs. Profit Sharing for Corporate Budgeting - An Experimental Analysis with Preplay Communication
No full textThis paper experimentally explores the efficiency of the Groves mechanism and a profit sharing scheme in a corporate budgeting context. Specifically, it examines the effects of anonymous communication on both incentive schemes. The results show that although the Groves mechanism is analytically superior to the profit sharing scheme, the latter turns out to be advantageous for headquarters in our experiment. This is essentially due to the effects of communication on both incentive schemes. Under the profit sharing scheme, communication improves coordination and reduces inefficient resource allocation. Under the Groves mechanism, however, it leads to stable collusion strategies of the participants, and thus increases compensation costs.

Kommunikation im Groves-Mechanismus – Ergebnisse eines Laborexperiments
No full textTheoretische Untersuchungen haben gezeigt, dass der Groves-Mechanismus als Anreizsystenn zur wahrheitsgemäßen Berichterstattung äußerst wünschenswerte Eigenschaften aufweist. So ergibt sich die wahrheitsgemäße Berichterstattung für alle Spieler als Gleichgewicht in dominanten Strategien. Offen ist jedoch, ob sich dieses Gleichgewicht auch unter realen Bedingungen zeigt und ob der Anreizmechanismus — wie von der Theorie vorhergesagt — manipulationsresistent ist. Diesen Fragen wird in einer experimentellen Studie nachgegangen. Dabei wird den Teilnehmern in einem von zwei Treatments die Möglichkeit zur anonymen Kommunikation gegeben. Die Ergebnisse zeigen, dass der Groves-Mechanismus in keinem der beiden Treatments zu wahrheitsgemäßer Berichterstattung führt. Während dies im Treatment ohne Kommunikation jedoch auf soziale Präferenzen bzw. Schwierigkeiten beim Verständnis des Anreizmechanismus zurückgeführt werden kann, zeigen sich im Kommunikationstreatment stabile Manipulationsstrategien der Teilnehmer bis in die letzte Runde

Andalusian Demand for Non-Market Goods from Mountain Olive Groves
No full textAgricultural multifunctionality is the recognition of the joint exercise of economic, environmental and social functions by this sector. In order to make this concept operative for the design of public policies, it is necessary to estimate the social demand for such functions. The main objective of this article is to present an empirical application in this line. For this purpose we have taken the agricultural system of mountain olive groves in Andalusia (Southern Spain) at risk of abandonment after the decoupling of the EU subsidies as a case study. The economic valuation technique used is the Choice Experiment. According to the results, there is a different contribution of each attribute to the improvement of the Society level of utility. The main finding of this study is the identification of a social demand for public goods and services provided by the mountains olive groves. This support for agricultural multifunctionality is heterogeneous in its perception by the citizens and the valuation of the various attributes that the concept involves. Taking into account the impact of an overall improvement in the attribute levels and the socioeconomic characteristics of the respondents, the results suggest that women, people with higher education levels, urban citizens and families with more than three members are those who benefit most from the provision of public goods by agriculture. There is a different contribution of each attribute to the improvement of the Society level of utility. Thus, and taking into account its WTP for each attribute, keeping rural population in their villages and fighting soil erosion (with 22.61 and 21.55/individual/year, respectively) seem to be the most valued functions of the mountain olive groves by Andalusian citizens. It follows the improvement of the visual quality of the rural landscapes (12.20/individual/year) and the reduction of food residuals (7.14/individual/year). Finally, the results of this study support the new orientation of the CAP which makes decoupled payments on compliance with a range of environmental, food safety, animal and plant health and animal welfare standards, as a result of which, the cross-compliance requirement of the EU agricultural support will, presumably, promote a net increase in social welfare. Yet, according to the results of this research, some efforts should be done to allow cross-compliance to reinforce the objectives of keeping rural population in rural areas and the improvement of the landscape.Agricultural multifunctionality, Economic valuation, Choice experiment, Olive groves, Andalusia (Spain), Crop Production/Industries, Demand and Price Analysis, Q11, Q18, Q24,
Secure Implementation Experiments: Do Strategy-proof Mechanisms Really Work?
No full textStrategy-proofness, requiring that truth-telling is a dominant strategy, is a standard concept used in social choice theory. Saijo et al. (2003) argue that this concept has serious drawbacks. In particular, many strategy-proof mechanisms have a continuum of Nash equilibria, including equilibria other than dominant strategy equilibria. For only a subset of strategy-proof mechanisms do the set of Nash equilibria and the set of dominant strategy equilibria coincide. For example, this double coincidence occurs in the Groves mechanism when preferences are single-peaked. We report experiments using two strategy-proof mechanisms. One of them has a large number of Nash equilibria, but the other has a unique Nash equilibrium. We found clear differences in the rate of dominant strategy play between the two.Experiment, Laboratory, Secure Implementation, Groves-Clarke, Pivotal, Learning
Uromys anak subsp. albiventer Groves & Flannery 1994, n.subsp.
No full textUromys anak albiventer n.subsp. Figs 6, 7, Table 1 Type material. HOLOTYPE, CSIRO Division of Wildlife and Ecology, Canberra no. CM.8532, adult male, skin and skull, from Uinba, Kubor Range, Papua New Guinea. Collected on 22 June 1963. Diagnosis. Distinguished from other subspecies as follows: i) coat more brown-toned; ii) venter much more broadly white, from throat to groin; iii) teeth smaller. Discussion. From Upper Bubu River region, as far west apparently as the Weyland Range. Of two specimens from Saiko, Bubu River, in the BM, one is entirely typical of this subspecies, while the other has the ventral white restricted as in nominotypical anak. In the Discriminant Analysis, both specimens fall with the present subspecies. To this subspecies belong a series of seven specimens (6 skins with skulls, 1 skull only) in the British Museum (Natural History), from the Kratke Mountains (Buntibasa, Kuraka, Apimuri) and east of the Hagen Range (Degabaga, Menebe). Certain other specimens may yet turn out to represent distinctive subspecies. These are from Lamende Range, near Mount Giluwe, and from Telefomin and Mount Elimbari. The Mount Giluwe specimen (BM 53.370) has the largest skull seen by us; the molars are however very small (molar row length 12.2 mm), and the tail is short (106% of head and body). The dorsal colouration is dark, and the venter has no white, being all grey; in these features it resembles U. a. rothschildi. The two Telefomin specimens are very small in size, but have large teeth. Five specimens from Mount Elimbari are also rather small in size, but have small teeth, and relatively long tails and ears. Only further material will allow us confidently to determine the nature of these variant populations.Published as part of Groves, C.
