A novel approach for candlestick technical analysis using a combination of the support vector machine and particle swarm optimization
Mahmoodi, Armin; Hashemi, Leila; Jasemi, Milad; … - In: Asian journal of economics and banking : AJEB 7 (2023) 1, pp. 2-24
Purpose - In this research, the main purpose is to use a suitable structure to predict the trading signals of the stock market with high accuracy. For this purpose, two models for the analysis of technical adaptation were used in this study. Design/methodology/approach - It can be seen that...

Corrupted by algorithms? : how AI-generated and human-written advice shape (dis)honesty
Leib, Margarita; Köbis, Nils; Rilke, Rainer Michael; … - 2023
Artificial Intelligence (AI) increasingly becomes an indispensable advisor. New ethical concerns arise if AI persuades people to behave dishonestly. In an experiment, we study how AI advice (generated by a Natural-Language-processing algorithm) affects (dis)honesty, compare it to equivalent...

Fairness in algorithmic decision systems : a microfinance perspective
Koefer, Franziska; Lemken, Ivo; Pauls, Jan - 2023
Fairness is a crucial concept in the context of artificial intelligence (AI) ethics and policy. It is an incremental component in existing ethical principle frameworks, especially for algorithm-enabled decision systems. Yet, unwanted biases in algorithms persist due to the failure of...

A multi-path delivery system with random refusal against online booking using Type-2 fuzzy logic-based fireworks algorithm
Maji, Somnath; Maity, Samir; Giri, Debasis; Castillo, Oscar - 2023
With the development of the internet and the availability of smart phones, online shopping and the number of digital buyers have increased enormously under the present social context (COVID-19). The major pitfall of this marketing system is the random non-availability of/refusal by customers....

Greedy-like Algorithm for Large-scale Dynamic Assortment Planning Problems
Lu, Lijue; Menezes, Mozart; Jalali, Hamed - 2023
Single-period dynamic assortment planning involves the retailer's decision of selecting a set of products to offer and determining their initial inventory levels, considering stochastic demand and dynamic substitution. The objective is to maximize the expected revenue, subject to a capacity...

Solving the Joint Location-Allocation-Routing Problem with a Branch-and-Cut Algorithm
Ando, Yosuke; Tóth, Sándor F.; Bagaram, Martin - 2023
We present a new mixed-integer program for a multi-depot, multi-vehicle capacitated location-allocation routing problem (LARP). The model simultaneously selects the locations of facilities, allocates customers to the intermediate facilities, and identifies the optimal number of capacitated...

Convergence Rates and Collusive Outcomes of Pricing Algorithms
Frick, Kevin Michael - 2023
Artificial intelligence algorithms are increasingly used by firms to set prices. Previous research on pricing algorithms shows that they can exhibit collusive behavior, but it has so far remained an open question whether they can do so in a reasonably short time. I develop a deep reinforcement...

A Simple Way Towards Fair Assortment Planning : Algorithms and Welfare Implications
Lu, Wentao; Sahin, Ozge; Wang, Ruxian - 2023
Large e-commerce retailers and department stores function as marketplaces for millions of sellers, and consumers rely on the platform's assortment and display decisions to examine different sellers and make purchase decisions. Traditionally, the primary objective of these marketplaces for...

Pricing via Artificial Intelligence : The Impact of Neural Network Architecture on Algorithmic Collusion
Zhang, Weipeng - 2023
Classic artificial intelligence (Q-learning) algorithms have been capable of consistently learning supra-competitive pricing strategies in infinitely repeated Nash-Bertrand pricing games without human communication. Such algorithms have been able to converge due to the temporal correlation of...
