ABSTRACT: Blind boxes are novel, gambling-like physical products that consumers can buy to obtain randomized content. In January 2022, non-binding, advisory compliance guidelines recommending certain best practices when marketing blind for sale were published in Shanghai, China. The relevant provisions, which include consumer protection and harm minimization measures such as setting age limits;...

Abstract Play-to-earn (P2E) is a new form of monetised gaming based on blockchain and crypto-currency technology. Such games offer opportunities to combine with speculative investment through the purchase tradable in-game currencies assets (non-fungible tokens). In this paper, we investigate profile people most likely be attracted emerging gaming. A sample 560 participants aged between 18-65 ( ...

Let A be a finite, nonempty subset of an abelian group. We show that if every element is sum two other elements, then has zero-sum subset. That is, (finite, nonempty) sum-full group not zero-sum-free.

Abstract   Vertical cooperative (co-op) advertising is typically a cost sharing mechanism and coordinated effort by the channel’s members in order to increase demand and overall profits. In this marketing strategy, the manufacturer shares a fraction of the retailer’s advertising investment. This paper studies the advertising and pricing decisions in a retailer-manufacturer supply chain in which...

Matching Pennies is a well-known example of a two player, zero-sum game. In this game, each of the players, the matcher and the mismatcher, flips a coin, and the payoffs are determined as follows. If the coins come up matching (i.e., both heads or both tails), then the matcher wins, so the mismatcher pays the matcher the sum of $1. If the coins do not match (i.e., one head and one tail), then t...

This paper is concerned with a new type of differential game problems of forward-backward stochastic systems. There are three distinguishing features: Firstly, our game systems are forward-backward doubly stochastic differential equations, which is a class of more general game systems than other forward-backward stochastic game systems without doubly stochastic terms; Secondly, forward equation...

In this lecture we will discuss 2-player zero sum games. Such games are completely competitive , where whatever one player wins, the other must lose. Examples of such games include chess, checkers, backgammon, etc. We will show that in such games: • An equilibrium always exists; • All equilibrium points yield the same payoff for all players; • The set of equilibrium points is actually the carte...

Effects of the listening context on responses to music largely have been neglected despite the prevalence of music in our everyday lives. Furthermore, there has been no research on the role of music in gambling environments (e.g., casinos, amusement arcades) despite gambling's increased popularity as a leisure pursuit. An exploratory observational study in gambling arcades was carried out to in...

This note reconsiders the Rubinstein bargaining game under assumption that a rejected offer is only costly to proposer who made offer. It shown then, classic result of Shaked that, in multilateral version this game, every division good can be sustained SPE no longer holds. Specifically, there are many SPE, but players’ (expected) payoffs unique. The further leads responder advantage.
