confounds: 使困惑

==notes by YNY==

用 「獨特性、相關性、合理性」DRP 方法來衡量實驗的困惑

==original abstract==

We present a distinctiveness, relevance and plausibility (DRP) method for systematically evaluating potential experimental confounds. A claim is a statement being inferred on the basis of experimental data analysis. A potential confound is a statement providing a prima facie reason why the claim is not justified (other than internal weakness). In evaluating whether a potential confound is problematic, we can start by asking whether the potential confound is distinctive from the claim; we can then ask whether it is relevant for the claim; and we can conclude by asking whether it is plausible in the light of the evidence.

New directions for modelling strategic behavior: Game-theoretic models of communication, coordination, and cooperation in economic relationships

==original Abstract==

In this paper, I discuss the state of progress in applications of game theory in economics and try to identify possible future developments that are likely to yield further progress. To keep the topic manageable, I focus on a canonical economic problem that is inherently game-theoretic, that of fostering efficient coordination and cooperation in relationships, with particular attention to the role of communication. I begin with an overview of noncooperative game theory’s principal model of behavior, Nash equilibrium. I next discuss the alternative “thinking" and “learning" rationales for how real-world actors might reach equilibrium decisions. I then review how Nash equilibrium has been used to model coordination, communication, and cooperation in relationships, and discuss possible developments

This chapter studies games played on fixed networks. These games capture a wide variety of economic settings including local public goods, peer effects, and technology adoption. We establish a common analytical framework to study a wide game class. We unearth new connections between games in the literature and in particular between those with binary actions, like coordination and best-shot games, and those with continuous actions and linear best replies. We review and advance existing results by showing how they tie together within the common framework. We discuss the game-theoretic underpinnings of key notions including Bonacich centrality, maximal independent sets, and the lowest and largest eigenvalue. We study the interplay of individual heterogeneity and the network and we develop a new notion – interdependence – to analyze how a shock to one agent affects the action of another agent. We outline directions for future research.

Too interconnected to fail: A survey of the interbank networks literature

The banking system is highly interconnected and these connections can be conveniently represented as an interbank network. This survey presents a systematic overview of the recent advances in the theoretical literature on interbank networks. We assess our current understanding of the structure of interbank networks, of how network characteristics affect contagion in the banking system and of how banks form connections when faced with the possibility of contagion and systemic risk. In particular, we highlight how the theoretical literature on interbank networks offers a coherent way of studying interconnections, contagion processes and systemic risk, while emphasizing at the same time the challenges that must be addressed before general results on the link between the structure of the interbank network and financial stability can be established. The survey concludes with a discussion of the policy relevance of interbank network models with a special focus on macro-prudential policies and monetary policy.

The Economics of Internet Media

Date: 2014
By: Peitz, Martin
Reisinger, Markus
URL: http://d.repec.org/n?u=RePEc:mnh:wpaper:37116&r=net
We survey the economics literature on media as it applies to the Internet. The Internet is an important driver behind media convergence and connects information and communication technologies. While new Internet media share some properties with traditional media, several novel features have appeared: On the content side, aggregation by third parties that have no editorial policy and user-generated content have become increasingly important. On the advertiser side, fine-tuned tailoring and targeting of ads based on individual user characteristics are common features on many Internet media and social networks. On the user side, we observe increased possibilities of time-shifting, multi-homing, and active search. These changes have gone hand-in-hand with new players entering media markets, including search engines and Internet service providers. Some of these players face novel strategic considerations, such as how to present search results. In response to these changes, an emerging economics literature focuses on the allocative and welfare implications of this new media landscape. This paper is an attempt to organize these contributions and provide a selective account of novel economic mechanisms that shape market outcomes of Internet media. A large body of work has focused on the advertising part of the industry, while some studies also look at content provision and the interaction between the two.

The Role of Experiments for the Development of Economic Theories

Schmidt, K. M. (2009). The role of experiments for the development of economic theories. Perspektiven der Wirtschaftspolitik, 10(s1), 14-30. DOI: 10.1111/j.1468-2516.2009.00304.x;  uni-muenchen.de 提供的 [PDF] ;

Abstract:

Economic experiments interact with economic theories in various ways. First of all they are used to test economic theories. However, they can neither confirm nor falsify them in a strict sense. They rather inform us about the range of applicability, the robustness and the predictive power of a theory. Furthermore, economic experiments discover and isolate phenomena and challenge economic theorists to explain them. Finally, many economic experiments are “material” models. They are used to analyze and predict how changes in the environment affect economic outcomes. However, they cannot offer an explanation for what we observe. This has to be provided by economic theory.
