An Economic Analysis of Difficulty Adjustment Algorithms in Proof‐of‐Work Blockchain Systems

International Economic Review, EarlyView.
ABSTRACT We study the stability of cryptocurrency systems through difficulty adjustment. Bitcoin's difficulty adjustment algorithm (DAA) exhibits instability when the reward elasticity of the hash rate is high, implying that a sharp price reduction could disrupt the current Bitcoin system.

A new A_n extension of Ramanujan's 1-psi-1 summation with applications to multilateral A_n series

, 2000
In this article, we derive some identities for multilateral basic hypergeometric series associated to the root system A_n. First, we apply Ismail's argument to an A_n q-binomial theorem of Milne and derive a new A_n generalization of Ramanujan's 1-psi-1 ...

Identification and Estimation of Large Network Games with Private Link Information

International Economic Review, EarlyView.
ABSTRACT We study the identification and estimation of large network games in which individuals choose continuous actions while holding private information about their links and payoffs. Extending the framework of Galeotti et al., we build a tractable empirical model of such network games and show that the parameters in individual payoffs are ...

Arbitrage Theorem and its Applications

Theory, Methodology, Practice, 2002
In my article I describe the concept of financial rate of return and the value of return in a very simple model first. Then as generalisation of the model we take an experiment, which has n possible outcomes.

From Classical to Modern Nonlinear Central Limit Theorems

Mathematics
In 1733, de Moivre, investigating the limit distribution of the binomial distribution, was the first to discover the existence of the normal distribution and the central limit theorem (CLT).

Winning is not the only metric: the complexity of control manipulation in knockout tournaments for a redefined goal

International Transactions in Operational Research, EarlyView.
Abstract We study control manipulation by generalizing the notion of success in knockout tournaments. The definition of success can be broadened to include other concepts of accomplishment rather than focusing solely on the identity of the tournament winner. Manipulation can be done in favor of diverse stakeholders.

New Laguerre-polynomials’ generating functions derived by virtue of operator Hermite-polynomial method and entangled state representation

AIP Advances
In this paper, we derive two new generating functions of Laguerre-polynomials, which look like the negative binomial theorem for the Laguerre function Lnx, by adopting the bi-partite entangled state representation and the operator-Hermite-polynomial HnX ...

Do robots boost productivity? A quantitative meta‐study

Journal of Economic Surveys, EarlyView.
ABSTRACT This meta‐study analyzes the productivity effects of industrial robots. More than 1800 estimates from 85 primary studies are collected. The meta‐analytic evidence suggests that robotization has so far provided, at best, a small boost to productivity. There is strong evidence of publication bias in the positive direction.

Binomial Theorem based on Annamalai's Binomial Identity

, 2022
This paper presents a binomial theorem and proof based on Annamalai’s binomial identity. The factorial function defined for non-negative integers, denoted by n!, is the product of all positive integers less than or equal to n. This theorem uses the factorial function and Annamalai’s binomial identity.

Model Ambiguity versus Model Misspecification in Dynamic Portfolio Choice

The Journal of Finance, EarlyView.
ABSTRACT We study aversion to model ambiguity and misspecification in dynamic portfolio choice. Risk‐averse investors (relative risk aversion γ>1$\gamma > 1$) fear return persistence, while risk‐tolerant investors (0<γ<1$0<\gamma <1$) fear mean reversion, when confronting model misspecification concerns of identically and independently distributed (IID)
