Promoting justice by treating people unequally: an experimental study

Which inequalities among individuals are considered unjust? This paper reports the results of an experiment designed to study distributive choices dealing with arbitrarily unequal initial endowments. In a three-person distribution problem where subjects either know or do not know their endowments, we find impartial behavior to be a stable pattern. Subjects either compensate for initial inequalities fully or not at all in both conditions, and they do so more often when they do not know their endowment than when they know it. Moreover, the type and the size of the good to be distributed also affect the frequency of impartial behavior.     

Competition and innovation: an experimental investigation

The paper analyzes the effects of more intense competition on firms’ investments in process innovations. More intense competition corresponds to an increase in the number of firms or a switch from Cournot to Bertrand competition. We carry out experiments for two-stage games, where R&D investment choices are followed by product market competition. An increase in the number of firms from two to four reduces investments, whereas a switch from Cournot to Bertrand increases investments, even though theory predicts a negative effect in the four-player case. The results arise both in treatments in which both stages are implemented and in treatments in which only one stage is implemented. However, the positive effect of moving from Cournot to Bertrand competition is more pronounced in the former case.     

Using or hiding private information? An experimental study of zero-sum repeated games with incomplete information

This paper studies the value of private information in strictly competitive interactions in which there is a trade-off between (i) the short-run gain of using information, and (ii) the long-run gain of concealing it. We implement simple examples from the class of zero-sum repeated games with incomplete information. While the empirical value of information does not always coincide with the theoretical prediction, the qualitative properties of the value of information are satisfied in the laboratory: (i) it is never negative, (ii) it decreases with the number of repetitions, (iii) it is bounded below by the value of the infinitely repeated game, and (iv) it is bounded above by the value of the one-shot game. In line with the theory, the empirical use of private information is almost complete when it should be, and decreases in longer interactions.     

Price leadership and firm size asymmetry: an experimental analysis

We use laboratory experiments to examine the effect of firm size asymmetry on the emergence of price leadership in a price-setting duopoly with capacity constraints. Independent of the level of size asymmetry, the unique subgame perfect equilibrium of our timing game predicts that the large firm is the price leader. Experimental data show that price leadership by the large firm is frequent, but simultaneous moves are also often observed. Profit outcomes in the previous period affect the subjects’ decisions to announce or wait in a way that hampers convergence to the equilibrium. Furthermore, while both small and large firms display a strong tendency to wait to announce their price when firm size asymmetry is low, they often set prices early when size asymmetry is high. Prices are higher when price setting is sequential rather than simultaneous and when firm size asymmetry is high. Hence, price leadership by either type of firm has an anti-competitive effect that is more pronounced when the size difference between firms is large.     

Peer pressure,social spillovers,and reciprocity: an experimental analysis

This study examines whether reciprocity is affected by what others know and do. Two types of social effects are investigated within the framework of a modified investment game. On the one hand, we assess the role played by the awareness that own choices are observed by another trustee—i.e., peer pressure. On the other hand, we measure the interaction between trustees’ choices—i.e., social spillovers. We find that peer pressure fosters reciprocity and, to a lesser extent, so do social spillovers.     

Remain silent and ye shall suffer: seller exploitation of reticent buyers in an experimental reputation system

By providing incentives for sellers to act in a trustworthy manner, reputation mechanisms can mitigate moral-hazard problems when particular buyers and sellers interact infrequently. However, these mechanisms rely on buyers sharing their private information about sellers, and thus may suffer from too little feedback when provision is costly. We experimentally compare a standard feedback mechanism to one in which sellers can inspect a buyer’s feedback-provision history, thus providing incentives to share private information even when costly. We find fairly high trust and trustworthiness in all markets, with buyers providing costly feedback, especially negative, sufficient to induce trustworthiness. However, feedback-provision histories did not improve outcomes, and at least weakly decreased trustworthiness with experienced participants, as this information enabled sellers to discriminate and ship less frequently to buyers lacking a reputation for information sharing.     

Uniform price auctions and fixed price offerings in IPOs: an experimental comparison

We compare uniform price auctions with fixed price offerings in Initial Public Offerings (IPO) using laboratory experiments. The experimental environment is based on the Biais and Faugeron-Grouzet (J. Financ. Intermed. 11:9–36, 2002) model. Standard predictions based on tacit collusion equilibria (TCE) suggest lower revenues in uniform price auctions, although alternative equilibria allow for higher revenues. In our experiment, there is no evidence that TCE are played. The experiment suggests that the uniform price auctions are superior to fixed price offerings in terms of raising revenues.

An experimental analysis of team production in networks

Experimental and empirical evidence highlights the role of networks on social outcomes. This paper tests the properties of exogenously fixed networks in team production. Subjects make the same decisions in a team work environment under four different organizational networks: the line, the circle, the star, and the complete network. In all the networks, links make information available to neighbors. This design allows us to analyze decisions across networks and a variety of subject types in a standard linear team production game. Contribution levels differ significantly across networks and the star is the most efficient incomplete network. Moreover, our results suggest that subjects act as conditional cooperators with respect to the information received from the network.     

The impact of downward social information on contribution decisions

In this paper we study the effect of downward social information in contribution decisions to fund public goods. We describe the results of a field experiment run in conjunction with the fundraising campaigns of a public radio station. Renewing members are presented with social information (information about another donor’s contribution) which is either above or below their previous (last year’s) contribution. We find that respondents change their contribution in the direction of the social information; increasing their contribution when the social information is above their previous contribution, and decreasing their contribution when the social information is below. We hypothesize about the psychological motivations that may cause the results and test these hypotheses by comparing the relative size of the upward and downward shifts. These results improve our understanding of cooperation in public good provision and suggest differential costs and benefits to fundraisers in providing social information.      

An experimental test of Taylor-type rules with inexperienced central bankers

We experimentally test monetary policy decision making in a population of inexperienced central bankers. In our experiments, subjects repeatedly set the short-term interest rate for a computer economy with inflation as their target. A large majority of subjects learn to successfully control inflation by correctly putting higher weight on inflation than on the output gap. In fact, the behavior of these subjects meets a stability criterion. The subjects smooth the interest rate as the theoretical literature suggests they should in order to enhance stability of the uncertain system they face. Our study is the first to use Taylor-type rules as a framework to identify inflation weighting, stability, and interest-rate smoothing as behavioral outcomes when subjects try to achieve an inflation target.     

Experimental asset markets with endogenous choice of costly asymmetric information

Asymmetric distribution of information, while omnipresent in real markets, is rarely considered in experimental financial markets. We present results from experiments where subjects endogenously choose between five information levels (four of them costly). We find that (i) uninformed traders earn the highest net returns, while average informed traders always perform worst even when information costs are not considered; (ii) over time traders learn to pick the most advantageous information levels (full information or no information); and (iii) market efficiency decreases with higher information costs. These results are mostly in line with the theoretical predictions of Grossman and Stiglitz (Am. Econ. Rev. 70:393–408, 1980) and provide additional insights that studies with only two information levels cannot deliver.     

Classification of natural language messages using a coordination game

The role of natural language communication in economic exchange has been the focus of substantial experimental analysis. Recently, scholars have taken the important step of investigating whether certain types of communication (e.g., promises) might affect decisions differently than other types of communication. This requires classifying natural language messages. Unfortunately, no broadly-accepted method is available for this purpose. We here describe a coordination game for classification of natural language messages. The game is similar in spirit to the “ESP” game that has proven successful for the classification of tens of millions of internet images. We compare our approach to self-classification as well as to classifications based on a standard content analysis. We argue that our classification game has advantages over those alternative approaches, and that these advantages might stem from the salient rewards earned by our game’s participants.     

The effect of MADD on drinking–driving activities: an empirical study

Since its establishment in 1980, MADD (Mothers Against Drunk Driving) has been instrumental in directing our nation's attention to the problems associated with drinking and driving activities. Through its legislative lobbying efforts, educational and victim support activities, MADD strives to increase the expected costs and reduce the expected benefits of driving under the influence of alcohol. The object of this paper is to develop and estimate a model which assesses the consequences of MADD's efforts on the incidence of drinking and driving. Using extensive data collected in California, a simultaneous equations model is estimated. The results suggest that MADD does have a deterrent effect upon the incidence of alcohol related accidents. Moreover, the effect is found to be stronger for alcohol related accidents with a non-fatal injury relative to those with a fatality.     

An experimental study of the impact of competition for Other People’s Money: the portfolio manager market

In this paper we experimentally investigate the impact that competing for funds has on the risk-taking behavior of laboratory portfolio managers compensated through an option-like scheme according to which the manager receives (most of) the compensation only for returns in excess of pre-specified strike price. We find that such a competitive environment and contractual arrangement lead, both in theory and in the lab, to inefficient risk taking behavior on the part of portfolio managers. We then study various policy interventions, obtained by manipulating various aspects of the competitive environment and the contractual arrangement, e.g., the Transparency of the contracts offered, the Risk Sharing component in the contract linking portfolio managers to investors, etc. While all these interventions would induce portfolio managers, at equilibrium, to efficiently invest funds in safe assets, we find that, in the lab, Transparency is most effective in incentivising managers to do so. Finally, we document a behavioral “Other People’s Money” effect in the lab, where portfolio managers tend to invest the funds of their investors in a more risky manner than their Own Money, even when it is not in either the investors’ or the managers’ interest to do so.     

Catch-up strategy of latecomer firms in Asia: a case study of innovation ambidexterity in PC industry

ABSTRACT

Over the last decade, more and more East Asian firms have moved beyond imitation and are delivering innovative products and services to the market. This study examines (a) how a latecomer firm in East Asia transformed its business model in pursuit of manufacturing its own brand and (b) how it managed its exploration and exploitation of the market and technology in response to growth and competition. Given the lack of research on firms transitioning from contract manufacturing (CM) to own-brand manufacturing (OBM), this study offers fresh insights into how Acer, a leading Taiwanese original equipment manufacturer (OEM), has pursued new ways of creating value using an innovation ambidexterity strategy to maximise its customer value and boost performance.

Acer is chosen for this case study because of its significance and impact in the global PC industry. Data were collected through interviews and secondary data analysis. Our findings show that innovation ambidexterity is a deliberate transition process, taking firms years to reshape their business models. Our findings also present a viable solution to sustainable competitive advantage and keys to firms’ renewal in face of environmental change. This study contributes to the innovation management literature, and the use of the innovation ambidexterity framework examines how firms explore new ways of creating and capturing value and face challenges.     

Dynamics of industry architecture and firms’ knowledge and capability development: an empirical study of industry transformation

There is a lack of empirical evidence supporting existing conceptualisations and particularly clarifying the underlying mechanisms involved in the role of dominant firms in industry transformation. This research undertook an in-depth single case study of how a firm managed its knowledge and capability development processes to shape the industry architecture to its benefit. We investigated how a dominant firm manipulates the interdependencies with local suppliers and positions itself at higher levels of the industry architecture hierarchy. Findings suggest that such processes take place over the course of several product innovation projects and across different levels of the product architecture. Such findings contribute to helping firms to manage their knowledge and capability development processes and transform the industry architecture to their advantage.     

The effect of religiosity and religious festivals on positional concerns – an experimental investigation of Ramadan

This article examines the effect of religion on positional concerns using survey experiments. We focus on two of the dimensions of religion – degree of religiosity and religious festivals. By conducting the experiments during both the most important day of Ramadan (the Night of Power) and a day outside Ramadan, we find that Ramadan overall has a small and negative impact on positional concerns. Detailed analyses based on the sorting of individuals’ degree of religiosity reveal that the decrease in the degree of positional concerns during Ramadan is mainly explained by a decrease in positionality among individuals with a low degree of religiosity.     

Simultaneous versus sequential public good provision and the role of refunds — An experimental study

We experimentally study contributing behavior to a threshold public good under simultaneous and sequential voluntary contribution mechanisms and investigate how refund policies interact with the mechanism. We find that, for a given refund rule, efficiency is greater under a sequential contribution mechanism than under a simultaneous contribution mechanism. Furthermore, for a given order of contributions, we find that full refund unambiguously achieves higher efficiency in the simultaneous mechanism while this is not the case in the sequential mechanism.     

The impact of personal beliefs on climate change: the “battle of perspectives” revisited

The paper proposes a multi-agent climate-economic model, the “battle of perspectives 2.0”. It is an updated and improved version of the original “battle of perspectives” model, described in Janssen (1996) and Janssen/de Vries (1998). The model integrates agents with differing beliefs about economic growth and the sensitivity of the climate system and places them in environments corresponding or non-corresponding to their beliefs. In a second step, different agent types are ruling the world conjointly. Using a learning procedure based on some operators known from Genetic Algorithms, the model shows how they adapt wrong beliefs over time. It is thus an evolutionary model of climate protection decisions. The paper argues that such models may help in analyzing why cost-minimizing protection paths, derived from integrated assessment models à la Nordhaus/Sztorc (2013), are not followed. Although this view is supported by numerous authors, few such models exist. With the “battle of perspectives 2.0” the paper offers a contribution to their development. Compared to the former version, more agent types are considered and more aspects have been endogenized.
