Repetition and signalling: experimental evidence from games with efficient equilibria

We report experiments where subjects generally fail to attain the efficient equilibrium of a one-shot game, but attain the efficient equilibrium of the repeated version. The results suggest that in the repeated game actions are used to signal future intentions.     

A strategic analysis of global warming: Theory and some numbers

We model the global warming process as a dynamic commons game in which the players are countries, their actions at each date produce emissions of greenhouse gases, and the state variable is the current stock of greenhouse gases. The theoretical analysis is complemented by a calibration exercise. The first set of results establishes theoretically, and then with illustrative numbers, the over-emissions due to a “tragedy of the commons.” The power of simple sanctions to lower emissions and increase welfare is then examined as is the effect of cost asymmetry. Finally, a complete theoretical charactrization is provided for the best equilibrium, and it is shown that it has a very simple structure; it involves a constant emission rate through time.     

Context matters to explain field experiments: Results from Colombian and Thai fishing villages

During the last decade, field experiments regarding the study of common pool resource governance have been performed that replicated earlier findings of laboratory experiments. One of the questions is how the decisions made by participants in rural communities are influenced by their experience. This paper presents the results of field experiments in Colombia and Thailand on fishery resources. Context information is derived from the communities via in-depth interviews, surveys and role playing exercises. The use of different methodological tools allowed to link decisions in field experiments with contextual variables for two fishery villages. Explanation of core variables in social dilemmas is given, the degree of cooperation levels, preferred rules, rule compliance and enforcement. Main findings include: i) fishermen made decisions in the field experiments that reflected their own experience and context, ii) agreements for rule crafting are possible only under specific conditions that guarantees livelihoods and sustainability, iii) the broader context determines cooperation levels at a local level, iv) inequalities in the sanctioning of rule breakers decrease the possibilities of reaching cooperation agreements, and v) high levels of trust among local fishermen is not a sufficient condition for resource sustainability, when trust in external rule makers and enforcers is low.

Behavioural responses to science-based eco-labelling: gold,silver, or bronze

This study uses unique data collected from field experiments to investigate consumer willingness to pay (WTP) for otherwise homogeneous commodities that provide different levels of environmental services. On average, individuals are willing to pay more for products that provide a higher level of ecosystem services. This effect is larger when the label contains symbols that explicitly differentiate the levels. The effect magnitude is further amplified when it contains brief information on the scientific basis for the levels. However, our results also suggest that the WTP premium for the superior product is smaller than the discount in WTP for the inferior product.     

Resolving Indeterminacy in Coordination Games: A New Approach Applied to a Pay-as-you-go Pension Scheme

This paper shows that when players ignore what outcome will emerge because of the presence of multiple equilibria, they can coordinate their expectations by forming an initial belief based on the principle of indifference followed by a process of reasoning that updates this belief. Since this procedure describes a natural way to form beliefs under indeterminacy, it is reasonable for every agent to conjecture that all the others form their beliefs according to the same logic. Exactly the fact that agents are aware that they form their beliefs following the same procedure allows them to successfully coordinate their expectations.      

Co-evolution of firms and strategic alliances: Theory and empirical evidence

This paper reviews the analogies of evolution and co-evolution within a business context. Specifically it examines some of the essential underlying assumptions of these theories including the unit of change, the unit of selection; the mechanism of selection, and the ability to change an organisational form. The usefulness of the application of theories of both evolution and co-evolution to explain firm behaviour is examined. Empirical evidence from the UK fresh produce industry is presented to illustrate that both firms and strategic alliances evolve, co-evolve and are subject to selection at individual, dyadic and group levels simultaneously.     

Constitutional coordination in unstable party systems: the Brazilian constitution of 1988

Constitutional assemblies are a common feature of many democratic transitions. However, the goal of coordinating constitutional choice would seem nearly impossible when assemblies are comprised of highly fragmented and volatile political parties. Building on Knight’s bargaining model, this article argues that the main challenge to coordination in unstable party systems is the procedural disequilibrium that results from incomplete information over breakdown payoffs. The likelihood of compromise in such circumstances is a function of the ideologies that frame constitutional choice and inform coalition-building. Thus, unstable party systems are not chaotic, although they may be deeply conflict-laden. These issues are illustrated empirically via the Brazilian Constitution of 1988, which demonstrates the possibilities for a stable constitutional order emerging from a fragmented and volatile party system.

Endogenous transfers in the Prisoner's Dilemma game: An experimental test of cooperation and coordination

We test a two-stage compensation mechanism for promoting cooperation in Prisoner's Dilemma games. Players first simultaneously choose binding non-negative amounts to pay their counterparts for cooperating, and then play the induced game knowing these amounts. In our games, all payment pairs consistent with mutual cooperation in subgame-perfect equilibrium transform these games into coordination games, with both mutual cooperation and mutual defection as Nash equilibria in the second stage. When endogenous transfer payments are not permitted, cooperation is much less likely. Mutual cooperation is most likely when the (sufficient) payments are identical, and it is also substantially more likely with payment pairs that bring the mutual-cooperation payoffs closer together. Both the Fehr–Schmidt and Charness–Rabin models predict that transfers that make final payoffs closer are preferred; however, they do not explain why equal transfers are particularly effective. Transfers are also effective in sustaining cooperation even when they are imposed and not chosen.     

Laboratory Testbeds and Non-Market Valuation: The Case of Bidding Behavior in a Second-Price Auction with an Outside Option

Researchers now use the lab to examine the behavioral underpinnings of valuation before the field application which some argue has less experimental control. But lab valuation work raises its own set of concerns when it uses private goods to explore non-market valuation behavior because private goods have substitutes often unaccounted for in the lab. Therefore, the lab as a tool to testbed field valuation work may be limited. Herein we design an induced valuation experiment to explore bidding behavior in a second-price auction with an outside option that is a perfect substitute for the auction commodity. Theory predicts that rational bidders will consider the prices of outside options when formulating bidding strategies, and will reduce their bids whenever their resale value exceeds the price of the outside option. Our results suggest that bidders account for outside options when formulating bids with behavior following comparative static predictions. In addition, we provide evidence concerning hypothetical versus actual behavior with induced values – the data suggesting a hypothetical bias in the level of bids but not in bid shaving.     

Simon's and Siegel's responses to the 'mixed strategy anomaly': a missed case in the sensitivity of economics to empirical evidence

In some of their papers published in the 1950s, Herbert Simonand Sidney Siegel responded to the so-called mixed strategyanomaly in ways which deserve more attention. They producednot only (i) immediate defences of the economic theory of theirown time, but also (ii) ideas and solutions that have laterturned out to be significant contributions to the developmentof the economic theory of choice and decision-making and theseparation of experimental economics from experimental psychology.These observations suggest that economics can be more responsiveto empirical anomalies than has been assumed. Furthermore, knowledgeof the desirable responsiveness to anomalies can provide meansof avoiding the non-desirable immunity to anomalies.     

A spatial analysis of provincial corporate income tax responses: evidence from Canada

Abstract.  Using a model of interdependent tax choices, and accounting for equalization entitlements and general transfers, this paper estimates – making use of a spatial econometric framework – corporate income tax-setting functions for all Canadian provincial governments. The results show that there is a statistically significant positive fiscal interaction among a subset of provinces and between all provinces and the federal government. Provincial corporate income taxes are also found to be negatively related to equalization entitlements, general federal transfers, and the federal corporate income tax. A robustness check on the fiscal relationship between Ontario and Quebec verifies the existence of significant bi-directional fiscal interdependencies. The paper also introduces U.S state corporate income taxes as covariates and examines their interaction with Canadian provinces.     

Using choice question formats to determine compensable values: The case of a landfill-siting process

Siting noxious facilities, such as community landfills, is a challenging problem for local planners who recognize the importance of economic efficiency and equity, political acceptance, and meeting federal regulatory standards. Meeting these criteria requires technical and socio-economic analyses in conjunction with public input. Planners may also recognize that political acceptance requires compensation for the host community, either in the form of monetary or in-kind transfers. Following Breffle and Rowe [Breffle, W.S., Rowe. R.D., 2002. Comparing choice question formats for evaluating natural resource tradeoffs. Land Econ. 78 (2), 298–314], we use a “resource-to-resource” paired-comparison survey method to estimate compensatory values associated with an in-county landfill for both the host and non-host communities. Our results indicate that while a host-community household's minimum willingness to accept payment for hosting a landfill may exceed a non-host-community household's maximum willingness to pay, a large difference in population sizes between the two communities enables the landfill to pass a Kaldor potential compensation test.     

Willingness to accept compensation for the environmental risks of oil transport on the Amazon: A choice modeling experiment

This paper looks at the question of whether subsistence level/indigenous people place a value on the preservation of ecosystems independent of direct impacts of environmental change, such as impacts on their production activities. The economics literature generally suggests that non-use values don't exist among the poor and in the informal sector of the economy. We examine this issue through a choice modeling experiment. A survey was conducted of rainforest communities who live on the banks of the Amazon River (Rio Solimões), in the vicinity of proposed oil and gas pipelines. The data were analyzed in the choice modeling framework, revealing relatively high amounts of compensation that were necessary in order to accept the potential ecosystem damages associated with oil transport, even if the people were completely compensated for direct damages such as loss of access to productive resources. These results suggest that environmental quality is important for its own sake, a result that is very different from the implicit assumption among many economists.     

Using Malmquist index to select the strategic partners in vertical integration: the case of Taiwan LED supply chain

In recent years, green technology efficiency has been one of the most interesting issues when referring to energy saving. The light-emitting diode (LED) is one of the competitive industries on green technology in Taiwan. The objective of this article is to select the vertical strategic partners of the 22 LED companies through investigating performance of integration. The Malmquist productivity index (MPI) is used to evaluate the average efficiency change from 2011 to 2015. The empirical results show that the productivity change was influenced by both catch-up effects and frontier effects. For upstream companies, the MPI of Tekcore is superior to others because it maintained technical efficiency and technological change. For downstream companies, most of them are performed well in technical efficiency than technological change. This article helps LED manufacturers select the appropriate strategic partners to achieve competitive advantage.     

Stationary solution to the overlapping generations model of fiat money: Experimental evidence

Overlapping generations model of fiat money yields an infinity of competitive equilibrium solutions, only one of which is stationary. Economies reported in this paper involved a sequence of overlapping generations of three or four individuals; each individual lived for two periods. In their young age individuals were endowed with chips that could be traded for fiat money wish the individuals of the old generation. In their old age, individuals could exchange their units o flat money for the consumption good. Results of the experiments exhibit some support for the stationary solution. The results are robust to two designs of exchange institutions (double oral auctior and supply schedule auction) and to two different endogenous ways of converting money into chips at the end of the game (average price prevailing during the last period the game is actually played and the average price forecast made during the last period the game is actually played).A preliminary version of this paper was presented at the meeting of the Economic Science Association and at the Federal Reserve Bank of Minneapolis. The authors are grateful for comments received from various participants at both presentations.

Stock market reactions to announcements of the board of directors: evidence from Italy

The board of directors plays an important role in corporate governance. It is an internal mechanism that controls and monitors the actions of managers and aligns the utility functions between corporate owners and managers. The board of directors performs multiple functions that concern, for example, the replacement of the managers, financial policy, the preparation of strategic plans and other actions that affect the performance of the company. The board plays an important role since on the one hand it controls the actions of management and on the other it advises the management regarding the strategies to be adopted. In this study, 100 announcements regarding the appointment of the board of directors of 100 Italian listed companies during the period 2012–2014 are investigated. The results show a positive reaction within 20 days around the announcement date. In four of the six time windows, cumulative abnormal returns (CARs) are positive and statistically significant. The positive reaction of the market would appear, however, to be linked more to the composition of the board of directors than to the size of the board of directors.     

The recent process of job polarization in Japan: evidence from 1980 to 2010

This study investigates the recent process of job polarization in Japan. We focus on three particular aspects: the relationship with business cycles, total hours rather than employment and age cohorts. We find that, regardless of whether the focus is employment or total hours, job polarization is concentrated in recessions and that job polarization has occurred mainly in younger-age cohorts.     

The internalization of externalities in the production of electricity: Willingness to pay for the attributes of a policy for renewable energy

This paper investigates the willingness to pay of a sample of residents of Bath, England, for a hypothetical program that promotes the production of renewable energy. Using choice experiments, we assess the preferences of respondents for a policy for the promotion of renewable energy that: (i) contributes to the internalization of the external costs caused by fossil fuel technologies; (ii) affects the short-term security of energy supply; (iii) has an impact on the employment in the energy sector; and (iv) leads to an increase in the electricity bill. Responses to the choice questions show that our respondents are in favour of a policy for renewable energy and that they attach a high value to a policy that brings private and public benefits in terms of climate change and energy security benefits. Our results therefore suggest that consumers are willing to pay a higher price for electricity in order to internalize the external costs in terms of energy security, climate change and air pollution caused by the production of electricity.
