Austen-Smith and Banks [Cheap talk and burned money, J. Econ. Theory 91(1) (2000) 1-16] study how money burning can expand the set of pure cheap talk equilibria of Crawford and Sobel [Strategic information transmission, Econometrica 50(6) (1982) 1431-1451]. I identify an error in the main Theorem of Austen-Smith and Banks, and provide a variant that preserves some of the important implications. I also prove that cheap talk can be influential with money burning if and only if it can be influential without money burning. This strengthens a result of Austen-Smith and Banks, but uncovers other errors in their analysis. Finally, an open conjecture of theirs is proved correct. 相似文献

This paper studies a simple model of observational learning where agents care not only about the information of others but also about their actions. We show that despite complex strategic considerations that arise from forward-looking incentives, herd behavior can arise in equilibrium. The model encompasses applications such as sequential elections, public good contributions, and leadership charitable giving. 相似文献

Would I lie to you? On social preferences and lying aversion 总被引:1,自引:0,他引:1
This paper reinterprets the evidence on lying or deception presented in Gneezy (Am. Econ. Rev. 95(1):384–394, 2005). We show that Gneezy’s data are consistent with the simple hypothesis that people are one of two kinds: either a person
will never lie, or a person will lie whenever she prefers the outcome obtained by lying over the outcome obtained by telling
the truth. This implies that so long as lying induces a preferred outcome over truth-telling, a person’s decision of whether
to lie may be completely insensitive to other changes in the induced outcomes, such as exactly how much she monetarily gains
relative to how much she hurts an anonymous partner. We run new but broadly similar experiments to those of Gneezy in order
to test this hypothesis. While we also confirm that there is an aversion to lying in our subject population, our data cannot
reject the simple hypothesis described above either.

This paper studies a model of strategic communication by an informed and upwardly biased sender to one or more receivers. Applications include situations in which (i) it is costly for the sender to misrepresent information, due to legal, technological, or moral constraints, or (ii) receivers may be credulous and blindly believe the sender's recommendation. In contrast to the predictions obtained in the benchmark cheap talk model, our model admits a fully separating equilibrium, provided that the state space is unbounded above. The language used in equilibrium is inflated and naive receivers are deceived. 相似文献

The Uruguay Round Agreement on agriculture attempted to lower distortions in global agricultural markets. However, the significant fall in commodity prices in the late 1990s may have reduced the incentives for both developed and developing countries to better integrate into world markets. This study analyzes price linkages and adjustment between developed and developing countries during the post–Uruguay Round period. Prices of two key commodities, long‐grain rice and medium‐hard wheat, are assembled for major exporters and producers. Results of multivariate cointegration analysis suggest partial market integration between developed and developing countries in the post–Uruguay Round period. Developed countries are found to be price leaders in these two markets, and in most cases, changes in their prices have relatively large impacts on those of the developing countries. Developing countries (e.g., Vietnam and Argentina) have faced considerable price adjustment due to changes in the developed countries' prices. 相似文献

This study investigates the evolving pattern of the interdependence among selected Asian emerging markets and three major stock markets (Japan, UK and US). Using rolling cointegration methods and the recently developed algorithms of inductive causation, we found that time-varying cointegration relationships exist among these stock markets. The results indicate that the wave of financial liberalization policies in the early 1990s led to a significant increase in market linkages which was later weakened during the 1997 Asian financial crisis. Furthermore, the data indicate that Japan and the US have the greatest influence on the emerging markets while the influence of Singapore and Thailand has increased since the Asian financial crisis. 相似文献

Participation is the initiation and continuance of an active process by which beneficiary groups influence the direction and execution of development activity. In the context of resource management participatory institutions often present an alternative when the market and/or the state fail to maintain resource stocks at desirable levels. This paper presents two case-studies of the emergence of participatory institutions and builds up analytical models that explain the process of their evolution in an inter-temporal framework.It is shown that the evolution, sustenance and replication of participation and its impact on levels of resource conservation depends on (a) the nature of the links between common and private property resources, (b) the possibility of taking advantage of scale economies, and finally (c) the distributional rules and arrangements. 相似文献

Design is increasingly being recognised as a key source of competitive advantage in the innovation economy of many countries. The key objective of this research was to understand the contribution by design graduates to creative industries innovative activities. Primary research was conducted to understand barriers and limitations of graduate contributions to such activities. The attributes and skills of graduates from the university and Vocational Education and Training sectors were the subject of the study. Two focus groups, one with the education sectors and the other with representatives from design firms, government institutions and design associations were held. Though each group of graduates was praised for having certain skill sets graduates from both sectors were found to be lacking in three key areas: problem solving, communication skills and commercial knowledge. A range of suggestions for systemic improvement were proposed as a result of the study. 相似文献

We study a persuasion game in which biased—possibly opposed—experts strategically acquire costly information that they can then conceal or reveal. We show that information acquisition decisions are strategic substitutes when experts have linear preferences over a decision maker's beliefs. The logic turns on how each expert expects the decision maker's posterior to be affected by the presence of other experts should he not acquire information that would turn out to be favorable. The decision maker may prefer to solicit advice from just one biased expert even when others—including those biased in the opposite direction (singular)—are available. 相似文献

Numerous alternative farming systems are proposed as solutions to the sustainability challenges of today's conventional farming systems. In this paper, we review the production, environmental, and socioeconomic performance of three widely discussed and promoted alternative farming systems—organic, smallholder, and urban agriculture. We show that both organic and smallholder agricultures have some benefits, but also entail important trade‐offs; organic has environmental benefits, and also livelihood, health, and nutritional benefits for producers and consumers, but is hampered by lower yields and higher prices. Smaller farms have higher yields and host higher biodiversity, but are hampered by lower incomes to farmers. Urban agriculture can take some pressure off rural landscapes, provide nutritional benefits to the urban poor, and engage urban dwellers in addressing food system challenges, but it simply cannot scale up to be a substantial solution in and of itself. We suggest that instead of focusing on alternative systems, we should identify pathways to sustainable farming for all systems, reforming conventional systems where they perform poorly, and transitioning to alternative systems in contexts where they perform best. 相似文献
