Atherosclerosis In Indigenous Tsimane: A Contemporary Perspective, Randall C. Thompson, Gregory S. Thomas, Angela D. Neuneubel, Ashna Mahadev, Benjamin Trumble, Edmond Seabright, Daniel K. Cummings, Jonathan Stieglitz, Michael Gurven, Hillard Kaplan

ESI Publications

The Horus and other research teams have found that atherosclerosis is not uncommon in ancient people through the study of their mummified remains (Murphy et al., 2003; Allam et al., 2009, 2011; Thompson et al., 2013, 2014). However, some have postulated that traditional hunter-gatherers are in some ways healthier than modern people and that they had very little atherosclerotic disease (O’Keefe et al., 2010). The aim of this study was to evaluate the burden of atherosclerosis in a population alive today but living a traditional lifestyle similar to that experienced by past populations. This led to the Tsimane Health and …

Little is known about brain aging or dementia in nonindustrialized environments that are similar to how humans lived throughout evolutionary history. This paper examines brain volume (BV) in middle and old age among two indigenous South American populations, the Tsimane and Moseten, whose lifestyles and environments diverge from those in high-income nations. With a sample of 1,165 individuals aged 40 to 94, we analyze population differences in cross-sectional rates of decline in BV with age. We also assess the relationships of BV with energy biomarkers and arterial disease and compare them against findings in industrialized contexts. The analyses test three …

Choice Flexibility And Long-Run Cooperation, Gabriele Camera, Jaehong Kim, David Rojo Arjona

ESI Working Papers

Understanding how incentives and institutions help scaling up cooperation is important, especially when strategic uncertainty is considerable. Evidence suggests that this is challenging even when full cooperation is theoretically sustainable thanks to indefinite repetition. In a controlled social dilemma experiment, we show that adding partial cooperation choices to the usual binary choice environment can raise cooperation and efficiency. Under suitable incentives, partial cooperation choices enable individuals to cheaply signal their desire to cooperate, reducing strategic uncertainty. The insight is that richer choice sets can form the basis of a language meaningful for coordinating on cooperation.

Connecting Higher Education To Workplace Activities And Earnings, Hung Chau, Sarah H. Bana, Baptiste Bouvier, Morgan R. Frank

Economics Faculty Articles and Research

Higher education is a source of skill acquisition for many middle- and high-skilled jobs. But what specific skills do universities impart on students to prepare them for desirable careers? In this study, we analyze a large novel corpora of over one million syllabi from over eight hundred bachelors’ granting US educational institutions to connect material taught in higher education to the detailed work activities in the US economy as reported by the US Department of Labor. First, we show how differences in taught skills both within and between college majors correspond to earnings differences of recent graduates. Further, we use …

Failed Secular Revolutions: Religious Belief, Competition, And Extremism, Jean-Paul Carvalho, Jared Rubin, Michael Sacks

ESI Working Papers

All advanced economies have undergone secular revolutions in which religious belief and institutions have been subordinated to secular forms of authority. There are, however, numerous examples of failed secular transitions. To understand these failures, we present a religious club model with endogenous entry and cultural transmission of religious beliefs. A spike in the demand for religious belief, due for example to a negative economic shock, induces a new and more extreme organization to enter the religious market and exploit the dissatisfaction of highly religious types with the religious incumbent. The eect is larger where institutional secularization is more advanced, for …

On The Welfare Role Of Redundant Assets With Heterogenous Forecasts, Shurojit Chatterji, Atsushi Kajii

Research Collection School Of Economics

We study a multiperiod model with a nominal bond that matures in one period and identify the set of e¢ cient allocations that can be sustained as Walrasian equilibria with heterogeneous forecasts. We next add a long maturity bond, which under perfect foresight would be a redundant asset, and show that it fundamentally expands the set of e¢ cient allocations that can be sustained as Walrasian equilibria. Indeed all wealth transfers compatible with e¢ ciency can arise endogenously. The key feature driving this conclusion are forecasting errors, which lead to ex post arbitrage opportunities that induce these income transfers.

Introducing New Forms Of Digital Money: Evidence From The Laboratory, Gabriele Camera

ESI Publications

Central banks may soon issue currencies that are entirely digital (CBDCs) and possibly interest bearing. A strategic analytical framework is used to investigate this innovation in the laboratory, contrasting a traditional “plain” tokens baseline to treatments with “sophisticated” interest-bearing tokens. In the experiment, this theoretically beneficial innovation precluded the emergence of a stable monetary system, reducing trade and welfare. Similar problems emerged when sophisticated tokens complemented or replaced plain tokens. This evidence underscores the advantages of combining theoretical with experimental investigation to provide insights for payments systems innovation and policy design.

Competing Social Influence In Contested Diffusion: Luther, Erasmus And The Spread Of The Protestant Reformation, Sascha O. Becker, Steven Pfaff, Yuan Hsiao, Jared Rubin

ESI Working Papers

The spread of radical institutional change does not often result from one-sided pro-innovation influence; countervailing influence networks in support of the status quo can suppress adoption. We develop a model of multiple and competing network diffusion. To apply the contested-diffusion model to real data, we look at the contest between Martin Luther and Desiderius Erasmus, the two most influential intellectuals of early 16th-century Central Europe. Whereas Luther championed a radical reform of the Western Church that broke with Rome, Erasmus opposed him, stressing the unity of the Church. In the early phase of the Reformation, these two figures utilized influence …

Asymmetric Effects In Geopolitical Risk And Foreign Reserves Accumulation Among Brics Countries, Kwame O. Asomaning

Doctoral Dissertations (DBA)

Over the past decade, the rise of Geopolitical Risk (GPR) has had a significant effect on macro financial variables, prompting central banks to accumulate reserves as a "war chest" to protect their economies from the detrimental effects of such shocks. This study examines the asymmetries in the long run, short run, and locational asymmetric effects on foreign reserves in the BRICS countries, using both the Nonlinear ARDL (NARDL) and Quantile ARDL (QARDL) models over the period 2000Q1–2021Q4. The results of the NARDL model suggest that GPR has long-run asymmetric effects for BRICS, while in the short run, all countries display …

Getting Dynamic Implementation To Work, Yi-Chun Chen, Richard Holden, Takashi Kunimoto, Yifei Sun, Tom Wilkening

Research Collection School Of Economics

We develop a new class of two-stage mechanisms, which fully implement any social choice function under initial rationalizability in complete information environments. We show theoretically that our Simultaneous Report (SR) mechanisms are robust to small amounts of incomplete information about the state of nature. We also highlight the robustness of the mechanisms to a wide variety of reasoning processes and behavioral assumptions. We show experimentally that a SR mechanism performs well in inducing truth-telling in both complete and incomplete information environments and that it can induce efficient investment in a two-sided hold-up problem with ex-ante investment. The SR mechanism also …

An Experimental Test Of Algorithmic Dismissals, Brice Corgnet

ESI Working Papers

We design a laboratory experiment in which a human or an algorithm decides which of two workers to dismiss. The algorithm automatically dismisses the least productive worker whereas human bosses have full discretion over their decisions. Using performance metrics and questionnaires, we find that fired workers react more negatively to human than to algorithmic decisions in a broad range of tasks. We show that spitefulness exacerbated this negative reaction. Our findings suggest algorithms could help tame negative reactions to dismissals.

God Games: An Experimental Study Of Uncertainty, Superstition, And Cooperation, Aidin Hajikhameneh, Laurence R. Iannaccone

Economics Faculty Articles and Research

This paper uses a novel lab experiment to test claims about the origins and functions of religion. We modify the standard public goods game, adding a computer-based agent that adjusts earnings in ways that might depend on players' contributions. Our treatments employ three different descriptions of the adjustment process that loosely correspond to monotheistic, atheistic, and agnostic interpretations of the computer's role. The adjustments neither mask players' contributions nor magnify their impact. Yet players in all three adjustment treatments contribute much more than those who play the standard public goods game. Players' contributions and survey responses show that adjustments induce …

Worker Welfare And Antitrust, Herbert J. Hovenkamp

All Faculty Scholarship

The important field of antitrust and labor has gone through a profound change in orientation. For the great bulk of its history labor has been viewed as a competitive threat, and the debate over antitrust and labor was framed around whether there should be a labor “immunity” from the antitrust laws. In just the last decade, however, the orientation has flipped. Most new writing views labor as a target of anticompetitive restraints imposed by employers. Antitrust is increasingly concerned with protecting labor rather than challenging its conduct.

Antitrust interest in labor markets is properly focused on two things. The smaller …

Alternative Approaches To Labor Values And Prices Of Production: Theory And Evidence, Deepankar Basu, Athanasios Moraitis

Economics Department Working Paper Series

In this paper, we discuss three approaches to estimating classical prices of production(long run equilibrium prices) in both a circulating capital model and a model that includes capital stock: the Standard Interpretation of Marx’s value theory, the New Interpretation of Marx’s value theory, and the Sraffian approach to prices of production. We add two refinements to both models: (a) allowing for differential wages rates across industries; and(b) taking account of unproductive industries in labor value calculations. We implement(a) the circulating capital models using harmonized input-output data from the World Input Output Database for 37 countries for the period 2000–2014, and …

The Effect Of Remote Work On Firm Level Productivity, Katherine Fullowan

Gettysburg Economic Review

This paper investigates the impact of remote work on firm-level productivity. To observe this trend, we develop a theoretical model to understand how an economy performs. We consider the economy as a collection of firms in an attempt to maximize profit. By observing a firms profit function, we are able to derive their productivity by maximizing a representative firm’s profit function. For simplicity purposes, this study treats labor as the only factor of production to focus solely on how changes in the number of remote workers impact productivity. We ultimately find that productivity increases when the number of remote workers …

Intrinsic Unrealism: The Ineffectiveness Of Neoclassical Economic Models, Robert N. Meyer

Gettysburg Economic Review

The idea of equilibrium and the usefulness of the neoclassical models that employ it are questionable due to the unrealistic built-in assumptions that they utilize, which have androcentric biases and fail to consider the open-endedness of human choice. This essay will replace the idea that neoclassical economic models are effective and that realism does not matter in the field of economics. It will rely on historical and contemporary sources in the areas of Philosophy, Sociology, Politics, and of course, Economics to explain why these unrealistic and androcentric assumptions nullify the usefulness of the neoclassical models that employ them. The essay …

Universal Basic Income (Ubi): A Cure-All Or Band-Aid?, Madison Beckner

Electronic Theses and Dissertations

With the triple crisis of capitalism looming and, in the U.S., a poorly performing welfare state, Universal Basic Income (UBI) has returned to popular attention. To assess whether this is warranted and, more importantly, to provide answer on the extent to which a UBI can or should be considered a cure-all, this work, first, examines the historical development of UBI proposals including those stemming from European Social Democrats and Libertarians. Next, pilot programs at the local, state, and national level are critically examined for their methodologies and empirical results. Turning, then, to theory on de-commodification, unpaid labor, and the equality-jobs …

Factors That Enable Or Hinder The Transition Of Some Gulf Cooperation Council (Gcc) Countries To Green Energy, Verkine Keukpanossian

CGU Theses & Dissertations

Gulf Cooperation Council (GCC) countries continue to play a strategic role in the global energy system. They account for a fifth of the global oil production and enjoy relatively high GDP per Capita, and their economies heavily rely on oil-producing and exporting at a time when the West is pushing towards net-zero, low-carbon emissions by 2050. This study focuses on the energy sector and takes a transdisciplinary look at Qatar, Saudi Arabia, and the United Arab Emirates (UAE) and tries to understand how these rentier monarchies that have built a solid global comparative advantage in producing and exporting oil and …
