A New World Order?: Considering Slaughter’S Notion Of The Disaggregated And Networked State, Darlene N. Moorman

The Downtown Review

This paper briefly explains Slaughter's (2004) argument for the emergence of a new world order defined by a disaggregated and networked state where the relevance of soft power has become all the more critical in conversations of politics and corresponding theory. This transformation (arising in the face of the so-called 'globalization paradox') is considered, exploring (a) what this means for the world system and (b) what concerns it may consequently bring.

Essays In Development Macroeconomics, Miguel Orozco Vazquez

Dissertations, Theses, and Capstone Projects

This dissertation consists of three chapters that cover topics on development macroeconomics.

Chapter 1 - Misallocation of Resources and Total Factor Productivity: Evidence from Mexico. This paper aims to measure the gross output loss due to misallocation of resources in the manufacturing and service sectors in Mexico during 2008-2018 and identify the inputs of production related to it. To do so, I use Mexican Economic Censuses and an extension of Hsieh and Klenow (2009). I also include resource misallocation computations using data processed with a Bayesian model for editing and imputing data to correct for measurement error (MEC data), which …

Three Essays In Experimental And Network Economics, John D. Mcmahan

Doctoral Dissertations

This dissertation consists of the three essays in network and experimental economics. The first essay explores the importance of endogenous bilateral connections and punishment networks in public good settings. I conduct a laboratory experiment that varies the incentive to form links among participants in a traditional Voluntary Contribution Mechanism game. I find that when link benefits are zero very few connections are formed, and very little punishment takes place. When link benefits are positive many links are formed and cooperation levels are increased. In general, we find evidence that participants strategically use the bilateral linking process to avoid punishment and …

The Economic Rationality Of Consumption In The Mycenaean Political Economy And Its Role In The Reproduction Of Social Personae: Modeling Prestige Networks., Devin Alexander Stephens

Electronic Theses and Dissertations

This thesis is a theoretical examination of the economic rationality of consumption as it existed within the Mycenaean political economy. Using a modified paradigm of social network analysis, a semiotic approach is used in the study of identity expression and economic stratification present at three Late Helladic cemeteries. In doing so, the claim that exchange strategies which existed outside of palatial redistribution were present in the Late Helladic was substantiated as a similar logic of mortuary stratification which existed during the palatial era was also found to have existed after the shift to the post-palatial era and the collapse of …

A Class Of N-Player Colonel Blotto Games With Multidimensional Private Information, Christian Ewerhart, Dan Kovenock

ESI Working Papers

In this paper, we study N-player Colonel Blotto games with incomplete information about battlefield valuations. Such games arise in job markets, research and development, electoral competition, security analysis, and conflict resolution. For M ≥ N + 1 battlefields, we identify a Bayes-Nash equilibrium in which the resource allocation to a given battlefield is strictly monotone in the valuation of that battlefield. We also explore extensions such as heterogeneous budgets, the case M ≤ N, full-support type distributions, and network games.

Strategic Problems With Risky Prospects, Alessandro Sontuoso, Cristina Bicchieri, Alexander Funcke, Einav Hart

ESI Working Papers

We study “hypothetical reasoning” in games where the impact of risky prospects (chance moves with commonly-known conditional probabilities) is compounded by strategic uncertainty. We embed such games in an environment that permits us to verify if risk-taking behavior is affected by information that reduces the extent of strategic uncertainty. We then test some implications of expected utility theory, while making minimal assumptions about individuals’ (risk or ambiguity) attitudes. Results indicate an effect of the information on behavior: this effect is triggered in some cases by a belief-revision about others’ actions, and in other cases by a reversal in risk …

A Class Of N-Player Colonel Blotto Games With Multidimensional Private Information, Christian Ewerhart, Dan Kovenock

ESI Working Papers

We consider a class of incomplete-information Colonel Blotto games in which N ≥ 2 agents are engaged in (N + 1) battlefields. An agent’s vector of battlefield valuations is drawn from a generalized sphere in L_p-space. We identify a Bayes-Nash equilibrium in which any agent’s resource allocation to a given battlefield is strictly monotone in the agent’s valuation of that battlefield. In contrast to the single-unit case, however, agents never enjoy any information rent. We also outline an extension to networks of Blotto games.

Can Friends Seed More Buzz And Adoption?, Vineet Kumar, K. Sudhir

Cowles Foundation Discussion Papers

A critical element of word of mouth (WOM) or buzz marketing is to identify seeds, often central actors with high degree in the social network. Seed identification typically requires data on the full network structure, which is often unavailable. We therefore examine the impact of WOM seeding strategies motivated by the friendship paradox to obtain more central nodes without knowing network structure. But higher-degree nodes may communicate less with neighbors; therefore whether friendship paradox motivated seeding strategies increase or reduce WOM and adoption remains an empirical question. We develop and estimate a model of WOM and adoption using data on …

Can Random Friends Seed More Buzz And Adoption? Leveraging The Friendship Paradox, Vineet Kumar, K. Sudhir

Cowles Foundation Discussion Papers

A critical element of word of mouth (WOM) or buzz marketing is to identify seeds, often central actors with high degree in the social network. Seed identification typically requires data on the full network structure, which is often unavailable. We therefore examine the impact of WOM seeding strategies motivated by the friendship paradox to obtain more central nodes without knowing network structure on adoption. Higher-degree nodes may be less effective as seeds if these nodes communicate less with neighbors or are less persuasive when they communicate; therefore whether friendship paradox motivated seeding strategies increase or reduce WOM and adoption remains …

Essays On Networks And Corporate Finance, Tatiana Salikhova

Graduate Theses and Dissertations

In my dissertation I explore how personal networks affect firms’ financial decisions. In the first essay, I study how social connections among divisional managers affect the capital allocation to divisions in diversified conglomerates. In contrast to the previous studies, I focus on the horizontal connections or connections formed among managers of the same level of corporate hierarchy. I show that connections among divisional managers lead to higher sensitivity of segment capital spending to segment’s growth opportunities, higher firm-level allocation efficiency and higher firm value. Additionally, firms tend to strategically assign better-connected managers to these segments, and connections help to reduce …

Three Essays On Nonstationary Time-Series Analysis And Network Dynamics, Yubo Tao

Dissertations and Theses Collection (Open Access)

My dissertation consists of three essays which contribute new theoretical results to nonstationary time-series analysis and network dynamics.

Chapter 2 examines the limit properties of information criteria (such as AIC, BIC, HQIC) for distinguishing between the unit root model and the various kinds of explosive models. The explosive models include the local-to-unit-root model, the mildly explosive model and the regular explosive model. Initial conditions with different orders of magnitude are considered. Both the OLS estimator and the indirect inference estimator are studied. It is found that BIC and HQIC, but not AIC, consistently select the unit root model when data …

Dusty Shoes: Appalachia Wisdom Fertilizing The Future Of Religious Leadership, Jill Crainshaw

Journal of Appalachian Health

Dust from their journeys through the hills and hollows of Appalachia clings to their shoes and has forever shaped their vocational journeys. This is a refrain I have distilled from the reflections of students who have participated in Wake Forest University School of Divinity’s multicultural contexts course that includes a 10-day sojourn in the mountains of North Carolina.

Selection In The Lab: A Network Approach, Aleksandr Alekseev, Mikhail Freer

ESI Working Papers

We study the selection problem in economic experiments by focusing on its dynamic and network aspects. We develop a dynamic network model of student participation in a subject pool, which assumes that students' participation is driven by the two channels: the direct channel of recruitment and the indirect channel of student interaction. Using rich recruitment data from a large public university, we find that the patterns of participation and biases are consistent with the model. We also find evidence of both short- and long-run selection biases between males and females, as well as between cohorts of students. Males tend to …

Centrality And Cooperation In Networks, Boris Van Leeuwen, Abhijit Ramalingam, David Rojo Arjona, Arthur Schram

Economics Faculty Articles and Research

We investigate the effects of centrality on cooperation in groups. Players with centrality keep a group together by having a pivotal position in a network. In some of our experimental treatments, players can vote to exclude others and prevent them from further participation in the group. We find that, in the presence of exclusion, central players contribute significantly less than others, and that this is tolerated by those others. Because of this tolerance, teams with centrality manage to maintain high levels of cooperation.

The Effects Of The Correspondent Banking Network On The Real Economy, Jack Brown

CMC Senior Theses

There is a longstanding academic debate regarding the role of financial networks. There is a tradeoff between improving the flow of funds and acting as a channel for contagion. This paper investigates the impact of banking networks on the real economy during the Great Depression. Building permit values are used as a proxy for real economic activity as implemented in previous research. A simple linear regression model estimated by ordinary least squares is used such that locational networks are differentiated from networks links to money centers and non-money centers. The results demonstrate that financial networks have both positive and negative …

Game Theory For Security Investments In Cyber And Supply Chain Networks, Shivani Shukla

Doctoral Dissertations

In a constantly and intricately connected world that is going digital, cybersecurity is imperative to not just the success but also the survival of a business. The ubiquitous digital transformation is fueled by a convulsive growth of devices and data that are leading important innovations in the domain of cyber-physical systems. However, this growth has also enabled internal and external threats to skyrocket, depicting the inherent dichotomy. With an evolving threat landscape, a perpetrator has to be successful once, while the defenders have to continually succeed in fending-off attacks to protect critical infrastructure and digital assets. Businesses are facing a …

Do Security Analysts Learn From Their Colleagues?, Kenny Phua, T. Mandy Tham, Chi Shen Wei

Research Collection Lee Kong Chian School Of Business

We examine how learning from colleagues affects security analyst forecast outcomes. We represent the brokerage house as an information network of analysts connected through industry overlaps in their coverage portfolios. Analysts who are more centrally connected in their brokerage network produce more accurate forecast estimates and generate more influential forecast revisions. Consistent with learning, more central analysts tend to unwind their colleagues’ recent forecast errors in their forecast revisions. Learning appears to benefit all colleagues, as working at more interconnected brokerages (i.e., denser networks) improves forecast accuracy for all analysts.

Trust In Cohesive Communities, Felipe Balmaceda Assoc Prof., Juan Escobar Assistant Professor

Felipe Balmaceda

This paper studies which social networks maximize trust and welfare when agreements are implicitly enforced. We study a repeated trust game in which trading opportunities arise exogenously and a social network determines the information each player has. We show that cohesive communities, modeled as social networks of complete components, emerge as the optimal community design. Cohesive communities generate some degree of common knowledge of transpired play that allows players to coordinate their punishments and, as a result, yield relatively high equilibrium payoffs. We also show that when news swiftly travel through the network, Pareto efficient networks are minimally connected: the …

Information And Interaction, Dirk Bergemann, Tibor Heumann, Stephen Morris

Cowles Foundation Discussion Papers

We study a linear interaction model with asymmetric information. We first characterize the linear Bayes Nash equilibrium for a class of one dimensional signals. It is then shown that this class of one dimensional signals provide a comprehensive description of the first and second moments of the distribution of outcomes for any Bayes Nash equilibrium and any information structure. We use our results in a variety of applications: (i) we study the connections between incomplete information and strategic interaction, (ii) we explain to what extent payoff environment and information structure of a economy are distinguishable through the equilibrium outcomes of …

Collaboration In Scientific Digital Ecosystems: A Socio-Technical Network Analysis, Philip Mutuma Munyua

Open Access Dissertations

This dissertation seeks to understand the formation, operation, organizational (collaboration) and the effect of scientific digital ecosystems that connect several online community networks in a single platform. The formation, mechanism and processes of online networks that influence members output is limited and contradictory. The dissertation is comprised of three papers that are guided by the following research questions: How does online community member’s productivity (or success) depend upon their ‘position’ in the digital networks? What are the network formation mechanism, structures and characteristics of an online community? How do scientific innovations traverse (diffuse) amongst users in online communities? A combination …

Negative Externalities, Network Effects, And Compatibility, Matthew G. Nagler

Publications and Research

Positive network effects arise where incremental product use increases the utility of users of compatible products (user-positive effects), but also in situations where product use imposes negative externalities that selectively affect the adopters of incompatible alternatives (nonuser-negative effects). This paper compares the social optimality of firms’ incentives for compatibility under these two regimes. Using a “location” model of differentiated products, I find that, under both regimes, incentives for unilateral action to increase compatibility tend to be suboptimal when firms’ networks are close in size, but they may be excessive for small firms when networks differ greatly in size. The result …

Helping A Microfinance Institution Select Its Clients: A Risk Analysis Using Social Networks, Sayantan Mitra, Varunavi Newar

Black & Gold

This paper formulates an objective mathematical model for a Microfinance Institution (MFI) to measure the credit worthiness associated with a potential client. We use concepts from network theory to determine the credit worthiness of an individual in relation to other households in the community. We use the concept of eigenvector centrality to evaluate the relative credit worthiness in the network. The latter part of the model focuses on the absolute measures of credit worthiness such as income, ownership of assets and risk of the proposed investment. This model would help MFIs reduce the risk of borrowing by ensuring that there …

Bilateral Bargaining With Externalities, Catherine De Fontenay, Joshua Gans

Catherine de Fontenay

This paper provides an analysis of a non-cooperative pairwise bargaining game between agents in a network. We establish that there exists an equilibrium that generates a coalitional bargaining division of the reduced surplus that arises as a result of externalities between agents. That is, we provide a non-cooperative justification for a cooperative division of a non-cooperative surplus. The resulting division is akin to the Myerson-Shapley value with properties that are particularly useful and tractable in applications. We demonstrate this by examining buyer-seller networks and vertical foreclosure.

Learning From Networks: Care Transitions, Market Competition, & Community Interventions, Glen P. Mays

Health Management and Policy Presentations

Social network analysis methods offer many avenues of inquiry for studying new developments in health policy and health care delivery. The expanding availability of large linkable electronic clinical and administrative data sources allows for novel SNA applications with dependent data structures. Opportunities include the study of delivery patterns within accountable care organizations (ACOs), and other multi-provider networks, price and quality competition within new health insurance exchanges, and population health effects attributable to complex community-level interventions.

Identification And Estimation Of Outcome Response With Heterogeneous Treatment Externalities, Tiziano Arduini, Eleonora Patacchini, Edoardo Rainone

Center for Policy Research

This paper studies the identification and estimation of treatment response with heterogeneous spillovers in a network model. We generalize the standard linear-in-means model to allow for multiple groups with between and within-group interactions. We provide a set of identification conditions of peer effects and consider a 2SLS estimation approach. Large sample properties of the proposed estimators are derived. Simulation experiments show that the estimators perform well in finite samples. The model is used to study the effectiveness of policies where peer effects are seen as a mechanism through which the treatments could propagate through the network. When interactions among groups …

Location, Location, Location: The Importance Of Proximity In Student Peer Evaluation, Roger White

Economics

The appropriateness of physical distances as a proxy for interpersonal networks is examined using data on peer evaluation scores collected from undergraduate student presentations in econometrics courses during the spring 2010 and spring 2011 semesters at Franklin & Marshall College. Employing the Tobit regression technique and decomposing the resulting coefficient estimates into marginal effects, we find that greater physical distance is negatively related to peer evaluation scores in the sense that greater distance lowers scores and reduces the likelihood that the evaluating student will assign the maximum possible score. Similarly, evaluating students assign higher scores to those student presenters they …

Private Debt Syndicates: Governance, Networks, And Syndicate Structure, William R. Mccumber

Graduate Theses and Dissertations

I examine the primary market for syndicated private credit agreements to U.S. firms within the context of contract theory with information asymmetries between contracting parties in a repeated game. Specific governance mechanisms determine a firm's cost of borrowing in syndicated credit agreements. Firms with governance mitigating agency risk between stakeholders, i.e. independent boards, strong shareholder monitoring, and greater CEO pay-performance sensitivity, enjoy lower borrowing costs. The interests of creditors and shareholders diverge with regard to external governance. Lenders charge higher spreads to firms at greater risk of acquisition and reward stronger firms with price concessions when they possess staunch anti-takeover …

Essays In Economic Growth And Development, Zhen Zhu

Graduate Theses and Dissertations

This dissertation consists of three chapters exploring the Solow Residual of the Solow growth model. Two central components of the Solow Residual have been studied in my doctoral dissertation. The first is the structural transformation, an internal adjustment process that helps the economy attain the optimal points on its Production Possibility Frontier by reallocating resources from the low-productivity sectors to the high-productivity sectors. The second is the technology diffusion, a positive externality process that pushes forward the economy's Production Possibility Frontier if it adopts the newer technology.

The first chapter of my dissertation is devoted to a case study of …

Measuring The Upstreamness Of Production And Trade Flows, Pol Antras, Davin Chor, Thibault Fally, Russell Hillbery

Research Collection School Of Economics

We propose two distinct approaches to the measurement of industry upstreamness (or average distance from final use) and show that they yield an equivalent measure. Furthermore, we provide two additional interpretations of this measure, one of them related to the concept of forward linkages. We construct this measure for 426 industries using the 2002 US input-output Tables. We also construct our measure using data from selected countries in the OECD STAN database. Finally, we present an application of our measure that explores the determinants of the average upstreamness of exports at the country level using trade flows for 2002.

The Emergence Of A Small World In A Network Of Research Joint Ventures, Stuart Mcdonald

Stuart McDonald

Using a data set spanning the period 1899-2000, we construct a network of RJVs and track the pattern of growth of this network over time. The resulting R&D network is emergent in the sense that RJVs are contained within it, connected to other RJVs by the existence of firms sharing membership with multiple RJVs. This paper shows that the largest growth in the R&D networks occurred during the last three decades of the Twentieth Century. During this growth period, the R&D network has a pattern of collaboration that can be characterised as having the “small world” property. This has implications …
