This paper analyses whether the audience dynamics of one content provider can explain the audience dynamics of a different content provider, and the resulting network of connections among providers. The type of connections in this network determines whether the audience of one creator influences or is susceptible to other creators’ audience. Grange...

In this paper we show experimentally that conditional cooperation, a phenomenon described in the private provision of public goods, is also present in group contests, where participants’ contributions to their group performance partially determines if they overcome a rival group. This environment allows us to identify new determinants of conditiona...

The sharing economy is revolutionizing the way consumers use goods and services. The aim of this study is to understand consumer motivations to be satisfied and to continue using ridesharing services. With this aim, we modify and extend the Expectation Confirmation Model by including social value as an additional factor to those previously studied...

A distinctive feature of recent revolutions was the key role of social media (e.g. Facebook, Twitter and YouTube). In this paper, we study its role in mobilization. We assume that social media allow potential participants to observe the individual participation decisions of others, while traditional mass media allow potential participants to see on...

We provide experimental evidence that panic bank runs occur in the absence of problems with fundamentals and coordination failures among depositors, the two main culprits identified in the literature. Depositors withdraw when they observe that others do so, even when theoretically they should not. Our findings suggest that panic also manifests itse...

We study experimentally cooperation in group contests under a new sharing rule that captures elements of coopetitive setups that are often characterized by the tension between cooperation and competition. It introduces an allocation of the obtained prize which is inversely proportional to individual efforts. We use it to study if the pervasive over...

We study experimentally an instrument to prevent bank runs in healthy banks. In particular, we extend the basic bank-run game, where depositors choose between withdraw or keeping their money deposited, with a third option, the possibility to relocate funds to a priority account that is less profitable, but which guarantees a payoff even in a bank r...

We study how lines form in front of banks. In our model, depositors choose first the level of effort to arrive early at the bank and then whether or not to withdraw their deposit. We argue that the informational environment (i.e., the possibility of observing the action of others) affects the emergence of bank runs and should, therefore, influence...

Public research policies have been promoting open-access publication in recent years as an adequate model for the dissemination of scientific knowledge. However, depending on the disciplines, its use is very diverse. This study explores the determinants of open-access publication among academic researchers of economics and business, as well as thei...

Technological development has transformed academic publication over the past two decades and new publication models, especially Open Access, have captured an important part of the publishing market, traditionally dominated by the Subscription publication model. Although Health Sciences have been one of the leading fields promoting Open Access, the...

We study experimentally if conditional cooperation occurs in group contests and how it is affected by 1) winning or losing the contest; and 2) if the group won or lost by chance or deservedly. We find that conditional cooperation prevails in group contests unconditionally and also if we control for the outcome of the contest, except when participan...

Purpose The purpose of this paper is to analyze how response time in a laboratory experiment on bank runs affects withdrawal decisions. Design/methodology/approach In the authors’ setup, the bank has no fundamental problems, depositors decide sequentially whether to keep the money in the bank or to withdraw, and they may observe previous decisions...

The use of online video by universities to communicate with their community is increasingly growing, however, the effect of the university characteristics on the online video impact remains overwhelmingly unstudied. Previous research has found a relation between research performance and the online video impact of the most prestigious universities...

There are situations in which competitors ally to pursue a common objective. This simultaneous presence of cooperation and competition is called coope-tition and we study it theoretically and experimentally in a group contest setup. More concretely, we analyze a group contest with a new sharing rule, that we call inverse proportional. This rule emb...

The updated H-index ranking for the top 100 universities listed in ARWU 2018. The H1000 score of a university is defined as the highest number H of videos with at least H × 1000 views.

YouTube has become the standard social network for the dissemination of university multimedia content, but the impact of academic online videos has been scarcely researched. This study covers this gap and provides a new dimension to evaluate university performance. Data and statistics of 416 YouTube accounts and ca. 190000 online videos of world cl...

En el presente trabajo estudiamos empíricamente si están alineados los objetivos entre los distintos participantes en los equipos de deporte base. Para ello, se ha encuestado a directivos, entrenadores y jugadores de fútbol de 28 clubes de cadete en sus campos de entrenamiento, preguntándoles acerca de sus objetivos. Encontramos que directivos y en...

During financial crisis, depositors and investors react quickly to the enviroment, thus financial authorities do often rely on the suspension of convertibility (i.e., freezing deposits) to prevent bank runs episodes. However, it is unclear how response time shapes decisions during bank runs. To cover this gap, we report experimental evidence on the...

Las universidades y los académicos se han incorporado al uso de las redes sociales como medio de interacción con la sociedad. Cada vez son más las universidades que hacen uso de las redes sociales, permitiéndoles diseminar sus esfuerzos sobre sus principales objetivos: educación, investigación y transferencia tecnológica. Recientemente se ha comenz...

We analyze the factors that determine the number of clicks on the “Like” button in online teaching videos, with a sample of teaching videos in the area of Microeconomics across Spanish speaking countries. The results show that users prefer short online teaching videos. Moreover, some features of the videos have a significant impact on the number of...

Thousands of depositors crowd in the door of a bank branch. “Where is our money?” they shout enraged. “We want our money back!” The scene, besides being part of the classic movie “It’s a wonderful life” (Frank Capra, 1946), reflects a reality that many people believed distant but that has re-arisen strongly in recent years. We refer to bank runs.

We analyze the factors that determine the number of clicks in the Like button in online teaching videos. We perform a study in a sample of Spanish-language teaching videos in the area of Microeconomics. The results show that users prefer short online teaching videos. Moreover, some other features of the videos have shown significant impact on the n...

We assess the effect of cognitive abilities on withdrawal decisions in a bank-run game. In our setup, depositors choose sequentially between withdrawing or keeping their funds deposited in a common bank. Depositors may observe previous decisions depending on the information structure. Theoretically, the last depositor in the sequence of decisions h...

We report experimental evidence on gender differences in financial decision-making that involves three depositors choosing whether to keep their money deposited or to withdraw it. We find that one's position in the line, the fact that one is being observed and observed decisions are key determinants in explaining the subjects’ behavior. Our main re...

We ran an experiment with users of Internet forums. In a dictator game, we find that the level of altruism is positively related to the activity in the forum. In a public good game, there is no relation between cooperation in the game and contribution to the content of the forum. Subjects are not more altruistic with partners from the same forum bu...

We report experimental evidence on the effect of observability of actions on bank runs. We model depositors’ decision-making in a sequential framework, with three depositors located at the nodes of a network. Depositors observe the other depositors’ actions only if connected by the network. Theoretically, a sufficient condition to prevent bank runs...

A distinctive feature of recent revolutions was the key role of social media (e.g. Facebook, Twitter and YouTube). We study the role of social media in mobilization. In a simple model we assume that while social me-dia allow to observe all previous decisions, mass media only give aggregate information about the state of a revolt. We show that when...

Les recents reformes educatives han portat a un augment de les tasques que els alumnes han de realitzar fora de l'horari lectiu. En aquest article estudiem la proporció d'alumnes que copien aquestes tasques. Per això, utilitzem la tècnica de llistes aleatoritzades, la qual millora la fiabilitat de les dades reportades pels estudiants perquè disminu...

A distinctive feature of recent revolutions was the key role of social media (e.g. Facebook, Twitter and YouTube). In a simple model we assume that while social media allow to observe all previous decisions, mass media only give aggregate information about the state of a revolt. We show, …rst, that when individuals' willingness to revolt is publicl...

We study a coordination problem where agents act sequentially. Agents are embedded in an obser-vation network that allows them to observe the actions of their neighbors. We …nd that coordination failures do not occur if there exists a su¢ ciently large clique. Its existence is necessary and su¢ cient when agents are homogenous and su¢ cient when ag...

In this paper, we use research chains across the citation graph as the basis for journal impact analysis. While some existing measures take into account research chains that end in a given journal, we calculate the proportion of research chains that include a journal, obtaining a new index of journal impact, Outerfactor, that is directly related to...

We study the effects of deposit insurance and observability of previous actions on the emergence of bank runs by means of a controlled laboratory experiment. We consider three depositors in the line of a bank, who decide between withdrawing or keeping their money deposited. We have three treatments with different levels of deposit insurance which r...

We report experimental evidence on the effect of observability of actions on bank runs. We model depositors’ decision-making in a sequential framework, with three depositors located at the nodes of a network. Depositors observe the other depositors’ actions only if connected by the network. Theoretically, a sufficient condition to prevent bank runs...

We build a small theoretical bank-run model which using network nests simultaneity and sequentiality. Information is largely determined by the links among depositors. We show that when position in the decision sequence is known, the existence of the link between the …rst and second agent is enough to eliminate coordination problems. When the positi...

Network generating processes as "growing networks" and "small worlds" do not take into account the intrinsic characteristics of nodes in order to explain structural properties. In this work, the process of network for-mation depends on the distribution of characteristics and how links are created depending on them. Structural properties are analyze...

How people search for their team-mates in intellectual activities such as R&D and coauthorship? This paper analyzes the effect of underlying social structures on the formation of networks of collabora-tions, similar to research and innovation networks. We design a field experiment, in which people join creative projects. These data are combined wit...

We develop, both theoretically and experimentally, a stereotypical environment that allows for co-ordination breakdown, leading to a bank run. Three depositors are located at the nodes of a network and have to decide whether to keep their funds deposited or to withdraw. One of the depositors has immediate liquidity needs, whereas the other two depo...
