Transparency and cooperation in repeated dilemma games: a meta study

We use data from experiments on finitely repeated dilemma games with fixed matching to investigate the effect of different types of information on cooperation. The data come from 71 studies using the voluntary contributions paradigm, covering 122 data points, and from 18 studies on decision-making in oligopoly, covering another 50 data points. We find similar effects in the two sets of experimental games. We find that transparency about what everyone in a group earns reduces contributions to the public good, as well as the degree of collusion in oligopoly markets. In contrast, transparency about choices tends to lead to an increase in contributions and collusion, although the size of this effect varies somewhat between the two settings. Our results are potentially useful for policy making, because they provide guidance on the type of information to target in order to stimulate or limit cooperation.     

Computing maximin efficient experimental designs using the methods of semidefinite programming

In the paper, we solve the problem of computing the maximin efficient design with respect to the class of all orthogonally invariant criteria. It turns out that on a finite experimental domain, the maximin efficient design can be computed by the methods of semidefinite programming. Using this approach, we can deal with the non-differentiability inherent in the problem, due to which the standard iterative procedures cannot be applied. We illustrate the results on the models of polynomial regression on a line segment and quadratic regression on a cube.     

Positioning Strategies for Animal-Friendly Products: A Social Dilemma Approach

Many consumers express concerns about the welfare of animals in agriculture, but often refrain from purchasing animal-friendly alternatives that address their concerns. To support consumers in making choices in line with their values and attitudes, this study approaches consumer animal-friendly product choice as a dilemma between maximizing the buyer's self-interest and maximizing societal interest. To address this social dilemma, we developed and tested positioning strategies that reinforce the animal welfare label with complementary consumption values (functional, emotional, social, and epistemic). The results from a choice experiment with Dutch chicken meat shoppers showed that two strategies—emotional and epistemic—effectively increase consumer value perceptions. These insights imply that animal-friendly products positioned to invoke emotion or curiosity drive consumers towards animal-friendly product choices, and that these strategies are most effective for consumers who base their choice solely on maximizing either self-interest or societal interest.     

Public sector efficiency in transition and beyond: evidence from Czech local governments

This article provides the first comparison of public sector efficiency in and beyond transition. We compare the comprehensive efficiency scores of 202 local governments in the Czech Republic in the transition period of 1995–1998 and the post-transition period of 2005–2008 and identify the period-specific determinants of local government efficiency. We observe convergence to the best practice frontier but also a growing efficiency gap between small and large governments. In both periods, municipal size and the main fiscal variables qualitatively affect efficiency in the same direction and in line with the fiscal stress hypothesis. Left-wing ideology is only robustly associated with cost inefficiency in the transition period. The geographic distances begin to matter for efficiency only in the post-transition period.     

The decentralization tradeoff for complementary spillovers

In this article, we examine how centralization and decentralization internalize positive spillovers of local public expenditures when a spill-in from foreign spending is not a substitute, but a complement to domestic spending. Specifically, we assume the production of two district-specific public goods out of two complementary district-specific inputs in a taste-symmetric two-district setting. We compare equilibria in non-cooperative decentralization and cooperative centralization for different spillovers, degrees of complementarity and cost-division rules, and control for the effects of strategic delegation and the feasibility of cross subsidies to the input in the foreign district. We find that centralization welfare-dominates decentralization in most institutional settings and for a wide range of parameters. Yet, we also identify conditions for decentralization to welfare-dominate centralization even in our setup where preferences are homogenous. The setup features three structural novelties: Strategic delegation improves provision and welfare in decentralization. In the absence of cross-district transfers, decentralized provision and welfare increase in spillovers. Welfare in centralization is generally non-monotonic in spillovers.     

Competitive Neutrality of the OECD Consensus Myth or Reality

This research paper gives into context ongoing changes in the balance of forces in the international markets caused not only by the crisis and the need to restore market-neutral internationally agreed system for state participation in the support for exports based on real economic criteria. The aim of this research is to demonstrate the changes of the balance of forces in the international markets. This paper presented the statistical data relating to development of GDP, indebtedness or value of exports or imports that the present changes in international markets and open discussion about the topic problem. This article recalled the basic principles of insurance and export financing with state support and also are presented current problems of implementation rules of the CONSENSUS. Due to the fact that state support for exports is an important internationally respected system it is necessary to overcome some doubts and bring to the system real market neutrality. Therefore, we ask whether are respected in practice the agreed principles of international state aid exports and what problems currently international markets and fundamentally different countries are struggling. It can be said that the rules CONSENSUS OECD has contributed to the creation of fair market conditions in international markets, but it can be also monitored over time to some extent being away from the demands of market neutrality. In view of these facts it can be considered as the basis of the current situation primarily to ensure a truly market and competitive neutrality of state support for exports.     

Informal settlement upgrading,assets and poverty alleviation: Evidence from longitudinal research in South Africa

This paper investigates the relationship between housing as an asset and the accumulation of other assets. Using data from a longitudinal research project stretching over nearly 25 years, we have found that besides actual income, there have also been improvements in self-perceived wealth ranking, asset holding, housing size, infrastructure access and human capital. Not all households have however benefited or been found to be better off. We have found that those households who had settled in Freedom Square after 1994 were indeed better off than the earlier settlers. Asset building is a slow process, one driven by stability (accessing urban land and secure tenure), finding an address, accessing education and finding work or remaining employed (though not necessarily in this particular sequence). Contrary to what the Department of Human Settlements suggests, we have found little evidence that informal settlement dwellers build assets by means of the secondary housing market.     

Understanding Preferences for Dietary Supplements and Fortified Food during Pregnancy: A Discrete Choice Experiment

Using a discrete choice experiment, we examine pregnant women’s preferences to determine the relative importance they place on product attributes when choosing between nutritionally fortified food and beverage products, and supplement tablets. The choice experiment was included in a cross-sectional web-based questionnaire completed by 857 pregnant Australian women. Latent class analysis identified four distinct consumer segments: ‘Nulliparous information seekers’ (42% of sample), ‘Lower-income milk-lovers’ (22%), ‘Older multiparous tablet users’ (16%), and ‘Young juice-lovers’ (20%). While nutrient levels were a strong driver of choice in the largest segment, over one-third of pregnant women were not influenced by levels of recommended nutrients (folate or iodine) in supplement products. Pregnancy supplements endorsed by a reputable government science agency were most appealing in three of the segments. The information gained regarding product preferences of different consumer segments can aid in targeting pregnant women and those planning pregnancy with more appropriate nutrition information, advice, and products.
