Who Helps Tsimane Children And Adults?, Eric Schniter, Daniel K. Cummings, Paul L. Hooper, Maguin Gutierrez Cayuba, Jonathan Stieglitz, Benjamin C. Trumble, Hillard S. Kaplan, Michael D. Gurven
ESI Working Papers
We consider several forms of helping behavior among Tsimane Amerindians of Bolivia, including provision of shelter, childcare, food, sickcare, loans, advice, and cultural influence. While kin selection theory is traditionally invoked to explain nepotistic nurturing of youngsters by closely related kin, much less attention has been given to understanding the help provided to children and adults by individuals without close genetic relatedness. To explain who provides the various forms of help that we consider, we evaluate support for several predictions derived from kin selection theory: that helpers are most often closely related and from an older generation, provide more help …

Did Covid-19 Disrupt The Stock Market Return And Volatility? A Meta-Analytic Approach, Masagus M. Ridhwan, Solikin M. Juhro, Affandi Ismail, Peter Nijkamp, Kelvin Ramadhan Hidayat
Bulletin of Monetary Economics and Banking
We provide a quantitative synthesis of the literature utilizing meta-regression analysis on the measurable effect of the combined health and economic crisis due to the COVID-19 pandemic on stock market returns and volatility. This study is conducted based on 104 studies published during the period 2020 to 2022. We find strong evidence of a negative publication bias for COVID-19 impacts on stock market returns and a positive bias on volatility. We document that COVID-19 has a moderate negative effect on stock market returns. Estimates based on intraday stock returns show a greater effect compared to those using daily returns, whereas …
Trade Liberalization With Brics: A Cge Model Of Egypt,

Trade Liberalization With Brics: A Cge Model Of Egypt, Kareem Ashraf
Theses and Dissertations
This paper presents an ex-ante impact assessment of a hypothetical FTA between Egypt and the BRICS from an Egyptian economy-wide and sectorial perspectives, with a granular look into manufacturing. The chosen methodology is a static SAM-based Computable General Equilibrium model calibrated to Egypt’s 2018-2019 Social Accounting Matrix (SAM). With respect to existing literature, the paper uniquely stands in considering an Egypt-BRICS FTA with a granular assessment of manufacturing subsectors and in running a simulation of Egypt’s trade liberalization with the wider BRICS alliance, including the accession of Saudi Arabia, UAE, Ethiopia, and Iran, which joined the bloc along with Egypt …
Ambiguity And Ambiguity Attitudes Across Auctions,

Ambiguity And Ambiguity Attitudes Across Auctions, Cary Deck, Paan Jindapon, Tigran Melkonyan, Mark Schneider
ESI Working Papers
Studies of ambiguity perceptions and attitudes are moving beyond the Ellsberg urn to examine people’s responses to ambiguity in naturally occurring events, games, and financial markets. In this study, we measure ambiguity perceptions and attitudes for market prices and allocations in four classical auction formats (first-price and second-price sealed bid auctions, English and Dutch clock auctions). We find ambiguity attitudes, representing individual preferences, are stable across auctions. However, the perceived ambiguity surrounding auction prices is lowest for English clock auctions which are obviously strategyproof (OSP), followed by second-price auctions which are strategyproof (SP), followed by a tie between first-price and …
The Interplay Of Interdependence And Correlation In Bilateral Trade,

The Interplay Of Interdependence And Correlation In Bilateral Trade, Takashi Kunimoto, Cuiling Zhang
Research Collection School Of Economics
Crémer and McLean (1988) show that the seller can extract full surplus almost always by an incentive compatible, individually rational mechanism in a single-unit auction model with a finite type space in which agents' beliefs are correlated and their valuations can be interdependent. We first show that this paradoxically positive result can be extended to a model of bilateral trades. To make it more realistic, we investigate when ex-post efficiency and ex-post budget balance in bilateral trades can also be achieved by an incentive compatible, individually rational mechanism. We identify a necessary condition for the existence of such mechanisms and …

Robust Implementation In Rationalizable Strategies In General Mechanisms, Takashi Kunimoto, Rene Saran
Research Collection School Of Economics
A social choice function (SCF) is robustly implementable in rationalizable strate-gies if every rationalizable strategy profile on every type space results in outcomes consistent with it. First, we establish an equivalence between robust implementation in rationalizable strategies and “weak rationalizable implementation”. Second, using the equivalence result, we identify weak robust monotonicity as a necessary and al-most sufficient condition for robust implementation in rationalizable strategies. This exhibits a contrast with robust implementation in interim equilibria, i.e., every equilib-rium on every type space achieves outcomes consistent with the SCF. Bergemann and Morris (2011) show that strict robust monotonicity is a necessary and …

Interim Regret Minimization, Wei He, Jiangtao Li, Kexin Wang
Research Collection School Of Economics
We consider a robust version of monopoly pricing when the seller only knows the bound on valuations and the mean of the distribution of the buyer’s value. The seller seeks to minimize interim regret, the forgone expected revenue due to not knowing the distribution of the buyer’s value. The optimal pricing policy randomizes over a range of prices; the support of the pricing policy is bounded away from zero.

Cognitive Abilities And Individual Earnings In Hybrid Continuous Double Auctions, Yan Peng, Jason Shachat, Lijia Wei, S. Sarah Zhang
ESI Working Papers
We study the influence of cognitive abilities, in particular reaction time, trader intuition (Theory of Mind), and cognitive reflection abilities, on human participants’ individual earnings when competing alongside algorithmic traders in continuous double auctions. In balanced markets, where each human trader has an algorithmic trader clone with the same valuations or costs, faster human reaction time significantly improves trading performance, while Theory of Mind can be detrimental to human trading performance, particularly for sellers. For unbalanced markets with humans and algorithmic traders on opposite sides of the market, the effects of cognitive abilities depend on trader role as well as …

Coordinated And Uncoordinated Punishment In A Team Investment Game, Vicente Calabuig, Natalia Jiménez-Jiménez, Gonzalo Olcina, Ismael Rodriguez-Lara
ESI Publications
Coordinated punishment occurs when punishment requires a specific number of punishers to be effective, otherwise, no damage will be inflicted on the target. While societies often rely on this punishment device, its benefits are unclear compared to uncoordinated punishment, where punishment decisions are substitutes. In this paper, we compare the efficacy of coordinated and uncoordinated punishment in a team investment game with two investors and one allocator. Our findings indicate that coordinated punishment results in higher levels of cooperation and reciprocity, as measured by the levels of joint investment and the return by allocators. Importantly, this does not translate into …

How Does Passive Investing Effect The Informational Efficiency Of Prices?, Brice Corgnet, Mark Desantis, Yan Peng, David Porter, Jason Shachat
ESI Working Papers
We investigate the causal effects of passive investing on informational efficiency and market quality metrics by developing a novel laboratory experiment that introduces Index trackers with exogenous passive investment flows. We find that, while improving liquidity, Index tracking hurts informational efficiency, confirming our main hypothesis. Furthermore, we observe violations of the law of one price, leading to widespread and persistent arbitrage opportunities. Additionally, our research uncovers that Active traders, particularly those with private information about asset values and high cognitive ability, reap benefits from the introduction of Index tracking.

Sleep Restriction Alters The Integration Of Multiple Information Sources In Probabilistic Decision-Making, Jeryl Y. L. Lim, Johanna M. Boardman, Clare Anderson, David L. Dickinson, Daniel Bennett, Sean P. A. Drummond
ESI Publications
The detrimental effects of sleep loss on overall decision-making have been well described. Due to the complex nature of decisions, there remains a need for studies to identify specific mechanisms of decision-making vulnerable to sleep loss. Bayesian perspectives of decision-making posit judgement formation during decision-making occurs via a process of integrating knowledge gleaned from past experiences (priors) with new information from current observations (likelihoods). We investigated the effects of sleep loss on the ability to integrate multiple sources of information during decision-making by reporting results from two experiments: the first implementing both sleep restriction (SR) and …

Representation And Bracketing In Repeated Games, Mouli Modak
ESI Working Papers
In this experimental paper, the author investigates the framing effect of different representations of multiple strategic settings or games on a player’s strategic behavior. Two representations of the same environment are employed, wherein a player engages in two infinitely repeated prisoner’s dilemma games. In the first representation (termed Split), the stage games are shown separately. In contrast, the second representation (termed Linked) displays a combined stage game. The choice bracketing, distinguishing between Narrow and Broad bracketing, is considered a potential cause behind any disparity in behavior between the two representations. The Split representation does not necessitate broad bracketing, whereas the …

Richard Iii, The Tudor Myth, And The Transition From Feudalism To Capitalism, Thomas E. Lambert
Faculty Scholarship
Over the last 10 years or so there has been a resurgence of interest in the English king Richard III, especially after his remains are found in 2012 after being lost or missing for centuries. Prior to this, there are many publications, reports, and documentaries alluding to a “smear” campaign being conducted against the king by either the Tudor monarchs who succeeded him and/or by their confederates and surrogates. It is alleged that this is done in order to promote and make the Tudor dynasty of the 16th Century (Henry VII, Henry VIII, Mary I, and Elizabeth I) appear …

Compellingness In Nash Implementation, Shurojit Chatterji, Takashi Kunimoto, Paulo Daniel Salles Ramos
Research Collection School Of Economics
A social choice function (SCF) is said to be Nash implementable if there exists a mechanism in which every Nash equilibrium outcome coincides with that specified by the SCF. The main objective of this paper is to assess the impact of considering mixed strategy equilibria in Nash implementation. To do this, we focus on environments with two agents and restrict attention to finite mechanisms. We call a mixed strategy equilibrium “compelling” if its outcome Pareto dominates any pure strategy equilibrium outcome. We show that if the finite environment and the SCF to be implemented jointly satisfy what we call Condition …

How Personalized Networks Can Limit Free Riding: A Multi-Group Version Of The Public Goods Game, Aaron S. Berman, Laurence R. Iannaccone, Mouli Modak
ESI Working Papers
People belong to many different groups, and few belong to the same network of groups. Moreover, people routinely reduce their involvement in dysfunctional groups while increasing involvement in those they find more attractive. The net effect can be an increase in overall cooperation and the partial isolation of free-riders, even if free-riders are never punished, excluded, or recognized. We formalize and test this conjecture with an agent-based social simulation and a multi-good extension of the standard repeated public goods game. Our initial results from three treatments suggest that the multi-group setting indeed raises overall cooperation and dampens the impact of …

Personal Lies, Gary Charness, Ismael Rodriguez-Lara
ESI Working Papers
Using the mind game, we provide experimental evidence that people are more likely to lie when they disclose non-personal information (e.g., reporting a number they thought of) compared with personal information (e.g., reporting the last digit of their birth year). Our findings suggest that the type of information is an important factor for lying behavior.

Axiomatic Marxian Exploitation Theory: A Survey Of The Recent Literature, Rylan Chinnock, Roberto Veneziani, Naoki Yoshihara
Economics Department Working Paper Series
In this paper we review recent developments in axiomatic studies of Marxian exploitation theory. First, given the acute controversy over the formal definition of exploitation during the 1970-1990s, we review the study of the axiomatic frame- work, which identifies some fundamental properties – technically, domain conditions – that any definition of exploitation should satisfy. Moreover, we provide a survey on the axiomatic studies about the proper measures of exploitation which coherently preserve the basic Marxian perceptions represented by two axioms, Profit- Exploitation Correspondence Principle and Class-Exploitation Correspondence Principle. Finally, we examine the relevance of the labour theory of value in …

Equal Predictive Ability Tests Based On Panel Data With Applications To Oecd And Imf Forecasts, Oguzhan Akgun, Alain Pirotte, Giovanni Urga, Zhenlin Yang
Research Collection School Of Economics
We propose two types of equal predictive ability (EPA) tests with panels to compare the predictions made by two forecasters. The first type, S-statistics, focuses on the overall EPA hypothesis, which states that the EPA holds, on average, over all panel units and over time. The second type, C-statistics, focuses on the clustered EPA hypothesis where the EPA holds jointly for a fixed number of clusters of panel units. The asymptotic properties of the proposed tests are evaluated under weak and strong cross-sectional dependence. An extensive Monte Carlo simulation shows that the proposed tests have very good finite sample properties, …
