Interim Rationalizable Implementation Of Functions, Takashi Kunimoto, Rene Saran, Roberto Serrano

Research Collection School Of Economics

This paper investigates rationalizable implementation of social choice functions (SCFs) in incomplete information environments. We identify weak interim rationalizable monotonicity (weak IRM) as a novel condition and show it to be a necessary and almost sufficient condition for rationalizable implementation. We show by means of robust examples that interim rationalizable monotonicity (IRM), found in the literature, is strictly stronger than weak IRM and that IRM is not necessary for rationalizable implementation, as had been previously claimed. These examples also demonstrate that Bayesian monotonicity, the key condition for full Bayesian implementation, is not necessary for rationalizable implementation. That is, rationalizable implementation …

The severity of infectious disease outbreaks is governed by patterns of human contact, which vary by geography, social organization, mobility, access to technology and healthcare, economic development, and culture. Whereas globalized societies and urban centers exhibit characteristics that can heighten vulnerability to pandemics, small-scale subsistence societies occupying remote, rural areas may be buffered. Accordingly, voluntary collective isolation has been proposed as one strategy to mitigate the impacts of COVID-19 and other pandemics on small-scale Indigenous populations with minimal access to healthcare infrastructure. To assess the vulnerability of such populations and the viability of interventions such as voluntary collective isolation, we …

Apolipoprotein-Ε4 Is Associated With Higher Fecundity In A Natural Fertility Population, Benjamin Trumble, Mia Charifson, Tom Kraft, Angela R. Garcia, Daniel K. Cummings, Paul L. Hooper, Amanda J.

In many populations, the apolipoprotein-ε4 (APOE-ε4) allele increases the risk for several chronic diseases of aging, including dementia and cardiovascular disease; despite these harmful effects at later ages, the APOE-ε4 allele remains prevalent. We assess the impact of APOE-ε4 on fertility and its proximate determinants (age at first reproduction, interbirth interval) among the Tsimane, a natural fertility population of forager-horticulturalists. Among 795 women aged 13 to 90 (20% APOE-ε4 carriers), those with at least one APOE-ε4 allele had 0.3 to 0.5 more children than (ε3/ε3) …

Bankers As Immoral? Some Parallels And Differences Between Aquinas’S Views On Usury And Marxian Views Of Banking And Credit, Thomas E. Lambert

Faculty and Staff Scholarship

Since ancient times the practices and ethics of bankers and banking in general have undergone a great deal of criticism. While lending is motivated by profit, and while households are not explicitly coerced into borrowing money, the justice of a system which exploits workers and at the same time encourages them to borrow money in order to maintain a certain standard of living can be viewed as sometimes unfair and perhaps immoral. The value of goods, according to St. Thomas Aquinas and Karl Marx, should mostly reflect the value of labor embodied in them, and for that reason, labor should …

Group Identity And The Formation Of Conditional Social Preferences Among Chinese Youth, Timo Heinrich, Jason Shachat, Qinjuan Wan

ESI Working Papers

Con icts between local and migrant populations have been ubiquitous in modern China. We examine the potential for longer-term amelioration of this conflict through successive generations and intergroup contact within integrated schooling. We adopt the perspective that in- and out-group biased behaviour structurally arises from group conditional social preferences. We assess the group-conditional social preferences of local and migrant children in a second-tier Chinese city, Xiamen, and the extent these preferences correlate with those of their parents. We find that local students have a greater likelihood of Egalitarian preferences and a lower likelihood of Generous preferences when allocating with locals …

Monetary Policy And Stagflation: A Trade-Off Between Price Stability And Economic Growth?, Leef H. Dierks

Journal of New Finance

Several euro area economies are likely to experience a stagflation in 2023. This situation is characterized by a combination of economic stagnation, i.e., GDP growth falling below its potential growth rate, and a pronounced increase in inflation as was last observed during the 1970s’ oil crisis. A stagflation presents the European Central Bank with a dilemma. Should it further tighten its monetary policy in an attempt to align euro area inflation (expectations) with its target of two per cent p.a. in the medium term? Or should the ECB re-adopt a more accommodative stance so as to stimulate economic growth in …

Recent Impacts Of Penny And Fixed Odds Wagering: What Does The Future Hold?, Thomas E. Lambert

Faculty and Staff Scholarship

In order hopefully to revive attendance at the tracks and/or fuel a resurgence in gambling (either in person or virtually), the last year has seen some recent wagering developments and changes at different horseracing tracks in the United States. At Ellis Park Racing and Gaming (Henderson, Kentucky) in the Evansville, Indiana metro area, penny wagering has been tried since the 2022 season to influence gambling revenues. Meanwhile, starting in 2022 Monmouth Park in New Jersey now offers “fixed odds” wagering as an alternative to parimutuel wagering for patrons who do not like the possible fluctuations in odds before a race …

Revisiting The Exchange Rate Pass- Through To Domestic Prices In Egypt, Ahmed Abdelhamid

Theses and Dissertations

Exchange rate pass-through (ERPT) refers to the extent to which the movements in the exchange rate influence domestic prices. This study revisits the exchange rate pass-through in Egypt using quarter data from 2006 to 2022. The study employs a Structural Vector Autoregression (SVAR) model to estimate the degree of ERPT. The findings suggest that ERPT in Egypt is incomplete, meaning that changes in the exchange rate do not fully pass through to consumer prices. The study also investigates the role of the money supply in absorbing the shocks in the nominal exchange rate. The study has important implications for policymakers …

Energetic Costs Of Testosterone In Two Subsistence Populations, Benjamin C. Trumble, Herman Pontzer, Jonathan Stieglitz, Daniel K. Cummings, Brian Wood, Melissa Emery Thompson, David Raichlen, Bret Beheim, Gandhi Yetish, Hillard Kaplan, Michael Gurven

ESI Publications

Objective

Testosterone plays a role in mediating energetic trade-offs between growth, maintenance, and reproduction. Investments in a high testosterone phenotype trade-off against other functions, particularly survival-enhancing immune function and cellular repair; thus only individuals in good condition can maintain both a high testosterone phenotype and somatic maintenance. While these effects are observed in experimental manipulations, they are difficult to demonstrate in free-living animals, particularly in humans. We hypothesize that individuals with higher testosterone will have higher energetic expenditures than those with lower testosterone.

Methods

Total energetic expenditure (TEE) was quantified using doubly labeled water in n = 40 Tsimane forager-horticulturalists …

Discrete Rule Learning In First Price Auctions, Jason Shachat, Lijia Wei

ESI Working Papers

We present a hidden Markov model of discrete strategic heterogeneity and learning in first price independent private values auctions. The model includes three latent bidding rules: constant absolute mark-up, constant percentage mark-up, and strategic best response. Rule switching probabilities depend upon a bidder's past auction outcomes and a myopic reinforcement learning dynamic. We apply this model to a new experiment that varies the number of bidders and the auction frame between forward and reverse. We find the proportion of bidders following constant absolute mark-up increases with experience, and is higher when the number of bidders is large. The primary driver …

Working Paper No. 81, A Critique Of Ideas Advanced By Nicholas Georgescu-Roegen, Chloe Kneedler

Working Papers in Economics

This inquiry seeks to establish that ideas advanced by economist Nicholas Georgescu-Roegen fall short and are deserving of a critique. Certainly, Georgescu-Roegen provided a foundation for the area of inquiry known as Ecological Economics. As suggested with the title, The Entropy Law and the Economic Process (1971), in this book Professor Georgescu-Roegen relates the Law of Entropy drawn from Physics to the economic process, in an effort to raise his concern over the finiteness of resources. In the modern, industrial economic system that he considers, he regards that goods with low entropy are consumed, and that their entropy increases until …

Working Paper No. 77, Deconstructing The Kardashian-Based Economy, Alec Van Rossum

Working Papers in Economics

This inquiry seeks to establish that connections can indeed be made between Thorstein Veblen's contributions towards our understanding of social stratification related to patterns of consumption, and the rise in importance of the Kardashian family. We take Veblen’s seminal and enduring book, The Theory of the Leisure Class: An Economic Study of Institutions [1899] and relate some of the ideas therein to what is being coined herein as a “Kardashian-Based Economy.” By drawing connections between selected ideas that Veblen's advanced, and some of the influences displayed by some members of the Kardashian family on consumer culture, we aim to understand …

Revisit The Moving Average Technical Trading Rule For The Nasdaq Composite Index, Louie Ren, Peter Ren, Jeffrey Yi-Lin Forrest

Pennsylvania Economic Review

We check the regression model assumptions via residual analysis using one dummy variable for Buy and Sell Days. Since the returns of the NASDAQ composite index is not stationary, it is inappropriate to use the Student T-test on Buy and Sell Days to analyze the efficiency of the market via moving average technical trading rules. As such, the Buy-Sell Days from the moving average trading rules have no predictability on daily NASDAQ index returns. This refutes the results of at least two studies on the NASDAQ Composite Index.

Endogenous Political Legitimacy: The Tudor Roots Of England’S Constitutional Governance, Avner Greif, Jared Rubin

ESI Working Papers

This paper highlights the importance of endogenous changes in the foundations of legitimacy for political regimes. It focuses on the central role of legitimacy changes in the rise of constitutional monarchy in England. It first defines legitimacy and briefly elaborates a theoretical framework enabling a historical study of this unobservable variable. It proceeds to substantiate that the low-legitimacy, post-Reformation Tudor monarchs of the 16th century promoted Parliament to enhance their legitimacy, thereby changing the legislative process from the “Crown and Parliament” to the “Crown in Parliament” that still prevails in England.

Fiscal Decentralization And Economic Performance In Selected Developing Federal Econom, Samuel Onyeka Okonkwo, Walter Okwudili Ugwuoke Phd

Bullion

Extant literatures on fiscal decentralization in most developing countries show more concerns on revenue allocation principle/sharing. Contrary to extant studies, this paper undertakes analysis of fiscal decentralization and economic performance in five emerging federal economies. The curiosity is to ascertain if poor economic performance in most emerging economies could be attributed to ill - structured fiscal decentralization. This objective was addressed using Panel Vector Autoregressive technique and impulse response function. The results showed that all the measures of fiscal decentralization such as revenue measure denoted as (FDC1), spending measure denoted as (FDC2) and revenue — spending measure or Simultaneity measure …

Digital Economy, Institutional Quality And Economic Growth In Selected Countries, Olabode P. Olofin Mr.

CBN Journal of Applied Statistics (JAS)

This study examines the role of digital economy and institutional quality on economic growth of Bangladesh, Ethiopia, Kenya, and Nigeria. The study adopts the feasible generalized least square method with annual panel data from 1985 to 2017. Results show that digital economy, human capital and knowledge worker, and democratic accountability promote economic growth, while corruption, socioeconomic conditions, and bureaucratic quality retard economic growth. Furthermore, interaction of digital economy with corruption promotes growth. However, the interaction of digital economy with institutional quality retards economic growth, which could be due to the deteriorating institutional quality and low level of economic digitalization in …
