Commentary: Reflections On Decision Research And Its Empiricism: Four Comments Inspired By Harrison, Nathaniel T. Wilcox

ESI Publications

"Generally I find Harrison's chapter cogent, interesting, and well-informed in details and particulars, and so do not speak of them. Instead, I reflect on four larger matters Harrison brings to my mind. These four matters are presented below as four separate sections, to be read as four separate and short comments (though the four sections do share a few threads)."

Monetary Equilibrium And The Cost Of Banking Activity, Paola Boel, Gabriele Camera

ESI Working Papers

We investigate the effects of banks’ operating costs on allocations and welfare in a low interest rate environment. We introduce an explicit production function for banks in a microfounded model where banks employ labor resources, hired on a competitive market, to run their operations. In equilibrium, this generates a spread between interest rates on loans and deposits, which naturally reflects the underlying monetary policy and the efficiency of financial intermediation. In a deflation or low inflation environment, equilibrium deposits yield zero returns. Hence, banks end up soaking up labor resources to offer deposits that do not outperform idle balances, thus …

Establishing Cryptocurrency Equilibria Through Game Theory, Carey Caginalp, Gunduz Caginalp

ESI Publications

We utilize optimization methods to determine equilibria of cryptocurrencies. A core group, the wealthy, fears the loss of assets that can be seized by a government. Volatility may be influenced by speculators. The wealthy must divide their assets between the home currency and the cryptocurrency, while the government decides the probability of seizing a fraction the assets of this group. We establish conditions for existence and uniqueness of Nash equilibria. Also examined is the separate timescale problem in which the government policy cannot be reversed, while the wealthy can adjust their allocation in reaction to the government’s designation of probability.

Differences In Tsimane Children’S Growth Outcomes And Associated Determinants As Estimated By Who Standards Vs. Within-Population References, Melanie Martin, Aaron Blackwell, Hillard Kaplan, Michael Gurven

Economics Faculty Articles and Research

Anthropometric measures are commonly converted to age stratified z-scores to examine variation in growth outcomes in mixed-age and sex samples. For many study populations, z-scores will differ if calculated from World Health Organization (WHO) growth standards or within-population references. The specific growth reference used may influence statistical estimates of growth outcomes and their determinants, with implications for biological inference. We examined factors associated with growth outcomes in a sample of 152 Tsimane children aged 0–36 months. The Tsimane are a subsistence-scale population in the Bolivian Amazon with high rates of infectious disease and growth faltering. To examine the influence of …

Do Economic Inequalities Affect Long-Run Cooperation & Prosperity?, Gabriele Camera, Cary Deck, David Porter

ESI Working Papers

We explore if fairness and inequality motivations affect cooperation in indefinitely repeated games. Each round, we randomly divided experimental participants into donor-recipient pairs. Donors could make a gift to recipients, and ex-ante earnings are highest when all donors give. Roles were randomly reassigned every period, which induced inequality in ex-post earnings. Theoretically, income-maximizing players do not have to condition on this inequality because it is payoff-irrelevant. Empirically, payoff-irrelevant inequality affected participants’ ability to coordinate on efficient play: donors conditioned gifts on their own past roles and, with inequalities made visible, discriminated against those who were better off.

Reconsidering Rational Expectations And The Aggregation Of Diverse Information In Laboratory Security Markets, Brice Corgnet, Cary Deck, Mark Desantis, Kyle Hampton, Erik O. Kimbrough

ESI Working Papers

The ability of markets to aggregate diverse information is a cornerstone of economics and finance, and empirical evidence for such aggregation has been demonstrated in previous laboratory experiments. Most notably Plott and Sunder (1988) find clear support for the rational expectations hypothesis in their Series B and C markets. However, recent studies have called into question the robustness of these findings. In this paper, we report the result of a direct replication of the key information aggregation results presented in Plott and Sunder. We do not find the same strong evidence in support of rational expectations that Plott and Sunder …

Dynamic Pricing With Fairness Concerns And A Capacity Constraint, Matthew Selove

Business Faculty Articles and Research

Although some firms use dynamic pricing to respond to demand fluctuations, other firms claim that fairness concerns prevent them from raising prices during periods when demand exceeds capacity. This paper explores conditions in which fairness concerns can or cannot cause shortages. In our model, a firm announces a price policy that states its prices during high and low demand, and customers must travel to a venue to learn the current price. We show that the interaction of fairness concerns with travel costs can cause the firm to set stable prices, which leads to shortages during high demand. However, if the …

The Political Economy Of Foreign Aid And Growth: Theory And Evidence, Sultan Mehmood, Avner Seror

ESI Working Papers

In this paper, we demonstrate that even when foreign aid is used to fund patronage, it may still have a positive - and significant - effect on economic growth in developing countries. First, we present a theory that formalizes the effect of aid on economic growth and patronage. Next, we provide evidence from Pakistan consistent with the predictions of the model that foreign aid increases economic growth, despite being used for patronage. The identification strategy we propose allows us to provide causal evidence for the predictions of the model.

Designing Call Auction Institutions To Eliminate Price Bubbles: Is English Dutch The Best?, Cary Deck, Maroš Servátka, Steven Tucker

ESI Working Papers

The bubble and burst pattern in asset market experiments is among the most replicable results in experimental economics. Numerous studies have searched for means to reduce this mispricing. Using controlled laboratory experiments, we compare mispricing in standard double auction markets to prices in two clock auctions. The double Dutch auction, shown to be more efficient than the double auction in commodity market experiments, does not eliminate bubbles. However, the English Dutch auction does yield prices reflective of underlying fundamentals and succeeds in taming bubbles even with inexperienced traders in the common declining fundamental value environment.

Methodological Differences Cannot Explain Associations Between Health, Anthropometrics, And Excess Resting Metabolic Rate, Michael Gurven, Benjamin Trumble, Jonathan Stieglitz, Dan Cummings, Hillard Kaplan, Aaron D. Blackwell, Gandhi Yetish, Herman Pontzer

ESI Publications

"We appreciate Ocobock's interest in methodological rigor. We largely agree with her commentary, which suggests that departures from standard protocols might have contributed to the high resting metabolic rate (RMR) measured for Tsimane. Indeed, our paper acknowledges many of the key departures from gold-standard indirect calorimetry methods of RMR assessment and attempts to adjust for several of these (Gurven et al., 2016). Bringing standard clinical methods into remote field settings often involves certain compromises, especially in our case, where RMR measurement was just one component of a large-scale health and aging project (Gurven et al., 2017). RMR data collection was …

Salience And Social Choice, Mark Schneider, Jonathan W. Leland

ESI Working Papers

The axioms of expected utility and discounted utility theory have been tested extensively. In contrast, the axioms of social welfare functions have only been tested in a few questionnaire studies involving choices between hypothetical income distributions. In this note, we conduct a controlled experiment with 100 subjects in the role of social planners that tests five fundamental properties of social welfare functions to provide a basic test of cardinal social choice theory. We find that four properties of the standard social welfare functions tested are systematically violated, producing an Allais paradox, a common ratio effect, a framing effect, and a …

A Time To Print, A Time To Reform, Lars Boerner, Jared Rubin, Battista Severgnini

ESI Working Papers

The public mechanical clock and movable type printing press were arguably the most important and complex technologies of the late medieval period. We posit that towns with clocks became upper-tail human capital hubs--clocks required extensive technical know-how and fine mechanical skill. This meant that clock towns were in position to adopt the printing press soon after its invention in 1450, as presses required a similar set of mechanical and technical skills to operate and repair. A two-stage analysis confirms this conjecture: we find that clock towns were 34-40 percentage points more likely to also have a press by 1500. The …

Counterparty Risk And The Establishment Of The New York Stock Exchange Clearinghouse, Asaf Bernstein, Eric Hughson, Marc Weidenmier

Business Faculty Articles and Research

We examine the effect of the establishment of the New York Stock Exchange (NYSE) clearinghouse in 1892 on counterparty risk using a novel historical experiment. During this period, the NYSE stocks were dual-listed on the Consolidated Stock Exchange (CSE), which already had a clearinghouse. Using identical securities on the CSE as a control, we find that the introduction of multilateral net settlement through a clearinghouse substantially reduced volatility of NYSE returns caused by settlement risk and increased asset values. Our results indicate that a clearinghouse can improve market stability and value through a reduction in network contagion and counterparty risk.

Endogenous Market Formation And Monetary Trade: An Experiment, Gabriele Camera, Dror Goldberg, Avi Weiss

ESI Working Papers

The theory of money assumes decentralized bilateral exchange and excludes centralized multilateral exchange. However, endogenizing the exchange process is critical for understanding the conditions that support the use of money. We develop a “travelling game” to study the emergence of decentralized and centralized exchange, theoretically and experimentally. Players located on separate islands can either trade locally, or pay a cost to trade elsewhere, so decentralized and centralized markets can both emerge in equilibrium. The former minimize trade costs through monetary exchange; the latter maximizes overall surplus through non-monetary exchange. Monetary trade emerges when coordination is problematic, while centralized trade emerges …

The Attack And Defense Games, Roman Sheremeta

ESI Working Papers

The attack and defense game is a game in which an attacker (a group of attackers) has an incentive to revise the status quo and a defender (a group of defenders) wants to protect it. The asymmetry in objectives creates incompatible interests and results in a mixed-strategy Nash equilibrium. However, this equilibrium could be heavily impacted by behavioral considerations.

On The Merit Of Equal Pay: Performance Manipulation And Incentive Setting, Brice Corgnet, Ludivine Martin, Peguy Ndodjang, Angela Sutan

ESI Publications

Work performance is often difficult to assess thus leaving room for manipulation of commonly-used metrics. We created a laboratory workplace in which we can precisely assess both work performance along with manipulation activities. Using two independent experiments we show that, whenever pay for performance is used, manipulation is pervasive leading to both a waste of organizational resources and a weakening of incentives. By contrast, paying organizational members equally effectively deters manipulation attempts leading to higher organizational production.

A Bias Aggregation Theorem, Mark Schneider

ESI Working Papers

In a market where some traders are rational (maximize expected utility) and others are systematically biased (deviate from expected utility due to some bias parameter, q), do equilibrium prices necessarily depend on q? In this note, focusing on the case where there is an aggregate and systematic bias in the population, we show that market prices can still be unbiased. Hence, we establish that systematically biased agents do not necessarily imply biased market prices. We show that the parametric model we use also predicts observed deviations from expected utility in laboratory and market environments.

Cooperation Among Strangers With And Without A Monetary System, Maria Bigoni, Gabriele Camera, Marco Casari

ESI Working Papers

Human societies prosper when their members move beyond local exchange and cooperate with outsiders in the creation of wealth. Collaboration of this type presents formidable challenges because interaction is impersonal, reciprocity is unfeasible and trust cannot be easily established. Here we study this cooperation problem by modeling strategic interaction among strangers through an Intertemporal Exchange Game. The setup can be easily implemented in the laboratory to study a variety of cooperation-enhancing institutions. In particular, we study the role of a fiat monetary system by introducing intrinsically worthless tokens that can be offered in exchange for cooperation. The experiments show that …

Humanomics: Moral Sentiments And The Wealth Of Nations For The Twenty-First Century, Vernon Smith, Bart J. Wilson

Economics Faculty Books and Book Chapters

Sometime in the last 250 years, economists lost sight of the full range of human feeling, thinking, and knowing in everyday life. Smith and Wilson show how Adam Smith's model of sociality can re-humanize twenty-first century economics by undergirding it with sentiments, fellow feeling, and a sense of propriety - the stuff of which human relationships are built. Integrating insights from The Theory of Moral Sentiments and the Wealth of Nations into contemporary empirical analysis, this book shapes economic betterment as a science of human beings.

Spanish California Missions: An Economic Success, Lynne Doti

Economics Faculty Articles and Research

Starting in 1769, the Spanish established missions in Alta California. A small band of soldiers, Franciscan priests and volunteers walked from Baja California to San Francisco Bay through semi-arid, scarcely populated land stopping occasionally to establish a location for a religious community. Usually two priests, a few soldiers and a few Indians from Baja California settled at the spot. Their only resources for starting an economy were themselves, a few animals and a nearby source of water. They attracted the local Indians to join the community and perform the work necessary to create a strong economy. After only a few …

A Full Characterization Of Best-Response Functions In The Lottery Colonel Blotto Game, Dan Kovenock, David Rojo Arjona

ESI Working Papers

We fully characterize best-response functions in Colonel Blotto games with lottery contest success functions.

Money Is More Than Memory, Maria Bigoni, Gabriele Camera, Marco Casari

ESI Working Papers

Impersonal exchange is the hallmark of an advanced society and money is one key institution that supports it. Economic theory regards money as a crude arrangement for monitoring counterparts’ past conduct. If so, then a public record of past actions—or memory—should supersede the function performed by money. This intriguing theoretical postulate remains untested. In an experiment, we show that the suggested functional equivalence between money and memory does not translate into an empirical equivalence: money removed the incentives to free ride, while memory did not. Monetary systems performed a richer set of functions than just revealing past behaviors.

Modeling Interactions Between Risk, Time, And Social Preferences, Mark Schneider

ESI Working Papers

Recent studies have observed systematic interactions between risk, time, and social preferences that constitute violations of `dimensional independence' and are not explained by the leading models of decision making. This note provides a simple approach to modeling such interaction effects while predicting new ones. In particular, we present a model of rational-behavioral preferences that takes the convex combination of `behavioral' System 1 preferences and `rational' System 2 preferences. The model provides a unifying approach to analyzing risk, time, and social preferences, and predicts how these preferences are correlated with reliance on System 1 or System 2 thinking.

A Dual System Model Of Risk And Time Preferences, Mark Schneider

ESI Working Papers

Discounted Expected Utility theory has been a workhorse in economic analysis for over half a century. However, it cannot explain empirical violations of 'dimensional independence' demonstrating that risk interacts with time preference and time interacts with risk preference, nor does it explain present bias or magnitude-dependence in risk and time preferences, or correlations between risk preference, time preference, and cognitive reflection. We demonstrate that these and other anomalies are explained by a dual system model of risk and time preferences that unless models of a rational economic agent, models based on prospect theory, and dual process models of decision making.

Using Response Times To Measure Ability On A Cognitive Task, Aleksandr Alekseev

ESI Working Papers

I show how using response times as a proxy for effort coupled with an explicit process-based model can address a long-standing issue of how to separate the effect of cognitive ability on performance from the effect of motivation. My method is based on a dynamic stochastic model of optimal effort choice in which ability and motivation are the structural parameters. I show how to estimate these parameters from the data on outcomes and response times in a cognitive task. In a laboratory experiment, I find that performance on a Digit-Symbol test is a noisy and biased measure of cognitive ability. …

Slow-Fast Analysis Of A Multi-Group Asset Flow Model With Implications For The Dynamics Of Wealth, Mark Desantis, David Swigon

Economics Faculty Articles and Research

The multi-group asset flow model is a nonlinear dynamical system originally developed as a tool for understanding the behavioral foundations of market phenomena such as flash crashes and price bubbles. In this paper we use a modification of this model to analyze the dynamics of a single-asset market in situations when the trading rates of investors (i.e., their desire to exchange stock for cash) are prescribed ahead of time and independent of the state of the market. Under the assumption of fast trading compared to the time-rate of change in the prescribed trading rates we decompose the dynamics of the …

On Booms That Never Bust: Ambiguity In Experimental Asset Markets With Bubbles, Brice Corgnet, Roberto Hernán-González, Praveen Kujal

ESI Working Papers

We study the effect of ambiguity on the formation of bubbles and on the occurrence of crashes in experimental asset markets à la Smith, Suchanek, and Williams (1988). We extend their framework to an environment where the fundamental value of the asset is ambiguous. We show that, when the fundamental value is ambiguous, asset prices tend to be lower than when it is risky although bubbles form in both the ambiguous and the risky environments. Additionally, bubbles do not crash in the ambiguous case whereas they do so in the risky one. These findings regarding depressed prices and the absence …

Spending Too Little In Hard Times, Alessandro Del Ponte, Peter Descioli

Political Science Faculty Articles and Research

People’s decisions to consume and save resources are critical to their wellbeing. Previous experiments find that people typically spend too much because of how they discount the future. We propose that people’s motive to preserve their savings can instead cause them to spend too little in hard times. We design an economic game in which participants can store resources for the future to survive in a harsh environment. A player’s income is uncertain and consumption yields diminishing returns within each day, creating tradeoffs between spending and saving. We compare participants’ decisions to a heuristic that performed best in simulations. We …

Conditional Independence In A Binary Choice Experiment, Nathaniel Wilcox

ESI Working Papers

Experimental and behavioral economists, as well as psychologists, commonly assume conditional independence of choices when constructing likelihood functions for structural estimation. I test this assumption using data from a new experiment designed for this purpose. Within the limits of the experiment’s identifying restriction and designed power to detect deviations from conditional independence, conditional independence is not rejected. In naturally occurring data, concerns about violations of conditional independence are certainly proper and well-taken (for well-known reasons). However, when an experimenter employs contemporary state-of-the-art experimental mechanisms and designs, the current evidence suggests that conditional independence is an acceptable assumption for analyzing data …
