Individual and Collective Information Acquisition: an Experimental Study
Individual and Collective Information Acquisition: An Experimental Study∗ P¨ellumb Reshidi† Alessandro Lizzeri‡ Leeat Yariv§ Jimmy Chan¶ Wing Suen‖ September 2020 Abstract Many committees|juries, political task forces, etc.|spend time gathering costly information before reaching a decision. We report results from lab experiments focused on such information- collection processes. We consider decisions governed by individuals and groups and compare how voting rules affect outcomes. We also contrast static information collection, as in classical hypothesis testing, with dynamic collection, as in sequential hypothesis testing. Generally, out- comes approximate the theoretical benchmark and sequential information collection is welfare enhancing relative to static collection. Nonetheless, several important departures emerge. Static information collection is excessive, and sequential information collection is non-stationary, pro- ducing declining decision accuracies over time. Furthermore, groups using majority rule yield especially hasty and inaccurate decisions. ∗We thank Roland Benabou, Stephen Morris, Salvo Nunnari, and Wolfgang Pesendorfer for very helpful discussions and feedback.

An important component of such collective decisions is the acquisition of information. -

Can There be “Libertarianism without Inequality”? Some Worries About the Coherence of Left-Libertarianism1 Mathias Risse John F. Kennedy School of Government, Harvard University October 25, 2003 1. Left-libertarianism is not a new star on the sky of political philosophy, but it was through the recent publication of Peter Vallentyne and Hillel Steiner’s anthologies that it became clearly visible as a contemporary movement with distinct historical roots. “Left- libertarian theories of justice,” says Vallentyne, “hold that agents are full self-owners and that natural resources are owned in some egalitarian manner. Unlike most versions of egalitarianism, left-libertarianism endorses full self-ownership, and thus places specific limits on what others may do to one’s person without one’s permission. Unlike right- libertarianism, it holds that natural resources may be privately appropriated only with the permission of, or with a significant payment to, the members of society. Like right- libertarianism, left-libertarianism holds that the basic rights of individuals are ownership rights. Left-libertarianism is promising because it coherently underwrites both some demands of material equality and some limits on the permissible means of promoting this equality” (Vallentyne and Steiner (2000a), p 1; emphasis added). -

Germany: a Global Miracle and a European Challenge
GLOBAL ECONOMY & DEVELOPMENT WORKING PAPER 62 | MAY 2013 Global Economy and Development at BROOKINGS GERMANY: A GLOBAL MIRACLE AND A EUROPEAN CHALLENGE Carlo Bastasin Global Economy and Development at BROOKINGS Carlo Bastasin is a visiting fellow in the Global Economy and Development and Foreign Policy pro- grams at Brookings. A preliminary and shorter version of this study was published in "Italia al Bivio - Riforme o Declino, la lezione dei paesi di successo" by Paolazzi, Sylos-Labini, ed. LUISS University Press. This paper was prepared within the framework of “A Growth Strategy for Europe” research project conducted by the Brookings Global Economy and Development program. Abstract: The excellent performance of the German economy over the past decade has drawn increasing interest across Europe for the kind of structural reforms that have relaunched the German model. Through those reforms, in fact, Germany has become one of the countries that benefit most from global economic integration. As such, Germany has become a reference model for the possibility of a thriving Europe in the global age. However, the same factors that have contributed to the German "global miracle" - the accumulation of savings and gains in competitiveness - are also a "European problem". In fact they contributed to originate the euro crisis and rep- resent elements of danger to the future survival of the euro area. Since the economic success of Germany has translated also into political influence, the other European countries are required to align their economic and social models to the German one. But can they do it? Are structural reforms all that are required? This study shows that the German success depended only in part on the vast array of structural reforms undertaken by German governments in the twenty-first century. -

COLLECTIVE ACTION FEDERALISM: a GENERAL THEORY of ARTICLE I, SECTION 8 Robert D
COLLECTIVE ACTION FEDERALISM: A GENERAL THEORY OF ARTICLE I, SECTION 8 Robert D. Cooter* & Neil S. Siegel** The Framers of the United States Constitution wrote Article I, Section 8 in order to address some daunting collective action problemsfacing the young na- tion. They especially wanted to protect the states from military warfare by fo- reigners andfrom commercial warfare against one another. The states acted in- dividually when they needed to act collectively, and Congress lacked power under the Articles of Confederation to address these problems. Section 8 thus au- thorized Congress to promote the "general Welfare" of the United States by tack- ling many collective actionproblems that the states could not solve on their own. Subsequent interpretationsof Section 8, both outside and inside the courts, often have focused on the presence or absence of collective action problems in- volving multiple states-but not always. For example, the Supreme Court of the United States, in trying to distinguish the "truly national" from the "truly local" in the context of the Commerce Clause, United States v. Morrison, 529 U.S. 598, * Herman Selvin Professor of Law, University of California at Berkeley. ** Professor of Law and Political Science, Duke University School of Law.

Memetic Media and Collective Identity Through Streamer Performance on Twitch
Selected Papers of #AoIR2020: The 21st Annual Conference of the Association of Internet Researchers Virtual Event / 27-31 October 2020 “I’VE GOTTA DO IT FOR THE BIT”: MEMETIC MEDIA AND COLLECTIVE IDENTITY THROUGH STREAMER PERFORMANCE ON TWITCH Nathan J Jackson School of the Arts and Media, UNSW Sydney Videogame livestreamers on the platform Twitch present a carefully curated version of themselves negotiated in part via interactions with their viewers. This persona is encoded not just through their live performance, but also through other platform features including streamer-specific emoticons (emotes) and audio-visual overlays triggered by stream events such as donations and subscriptions (alerts). From these customisable features emerges a complicated feedback loop between the streamer and non-streamer participants that ultimately results in a set of collective values performed and refined by both parties over time. In this paper I interrogate how the incorporation of Internet memes into streaming personas creates accessible avenues for communication with and between members of this collective that contribute significantly to this value system. Memes operate based on a core duality between commitment to a fixed set of properties and creative variation – this duality has been referred to using several different terminologies (see Wiggins & Bowers, 2015; Milner, 2016; Phillips & Milner, 2018). As such, there is a necessary plurality to memes considering their diverse manifestations, as emphasised by Limor Shifman’s (2014) definition of the term. This complicates the meaning-making process of memes as they carry not just the intended value of each manifestation’s creator, but also the latent values of the meme template and the referent texts. -
Germany's Flirtation with Anti-Capitalist Populism

ENGELEN ecent rhetorical attacks against interna- tional corporate investors from the top echelons of Germany’s governing Social Democratic Party, coupled with the crashing defeat of the Red-Green coalition in the latest state elections and the German chancellor’s unexpected move to call a national election a year Germany’s flirtation with earlier than scheduled—all these developments can be seen as Rpart of an “end game” for Gerhard Schröder and the Red-Green coalition. anti-capitalist populism. In a major speech on the future SPD agenda at the party headquarters on April 13, party chairman Franz Müntefering zoomed in on “international profit-maximization strategies,” “the increasing power of capital,”and moves toward “pure cap- italism.” Encouraged by the favorable response his anti-capi- talistic rhetoric produced among party followers and confronted with ever more alarming polls from the Ruhr, he escalated the war of words. “Some financial investors spare no thought for the people whose jobs they destroy,” he told the tabloid Bild. “They remain anonymous, have no face, fall like a plague of locusts over our companies, devour everything, then fly on to the next one.” When a so-called “locust list” of financial investors leaked from the SPD headquarters to the press, the “droning buzz” of Klaus C.

The Cognitive Mechanisms Underlying Information Cascades
1 Wise or mad crowds? The cognitive mechanisms underlying 2 information cascades 1 1;2 3 Alan N. Tump ([email protected]), Tim Pleskac , Ralf H. J. M.

Rather, multiple people decide sequentially, setting the stage 8 for information cascades whereby early-deciding individuals can influence others' 9 choices. To understand how information cascades through social systems, it is es- 10 sential to capture the dynamics of the decision-making process. We introduce the 11 social drift-diffusion model to capture these dynamics. We tested our model using 12 a sequential choice task. The model was able to recover the dynamics of the social 13 decision-making process, accurately capturing how individuals integrate personal 14 and social information dynamically over time and when they timed their decisions. 15 Our results show the importance of the interrelationships between accuracy, con- 16 fidence, and response time in shaping the quality of information cascades. The 17 model reveals the importance of capturing the dynamics of decision processes to 18 understand how information cascades in social systems, paving the way for appli- 19 cations in other social systems. 20 21 Keywords: collective intelligence, information cascades, sequential decision-making, social 22 information, confidence, herding, conformity, social impact, collective behaviour 23 Main 24 In many situations|be they financial investments, consumer choices, or simply crossing the street| 25 one is generally not making a decision alone.
