In this study, the strategic interaction between traffic police and the driver is analyzed using game theory in the form of a two-stage dynamic game with incomplete information that the type of players is determined by nature. In the first stage, the police decide whether to fine or not, and in the second stage, the driver decides whether to pay a bribe or not. The driver compares the amount of the fine and the cost of the bribe. It can be concluded that the more lawful the police, the lower the bribe payment. Punishment of bribe recipients and payers can also prevent bribery and help eradicate possible corruption in this important organ of the country. Manuscript profile

This paper seeks to explore the nonlinear association between liquidity indicators and debt repayment capacity in relation to asset returns. For this purpose, the Panel Smooth Transition Regression (PSTR) method was employed to examine the nonlinear impact of liquidity indicators (including the ratios of current assets to total deposits, total loans granted to total deposits, and total loans granted to total assets and debt payment capacity indicators (such as the debt ratio and interest coverage ratio) on asset returns from 2011 to 2020. The findings revealed a nonlinear effect of all calculated indicators on asset returns. The magnitude and manner of the independent variables' influence on asset returns varied at different levels, with noticeable distinctions in the effect before and after the threshold value of 1.0586. In light of these results, bank policymakers can strategically select an optimal liquidity level to enhance bank profitability based on asset returns. Manuscript profile

The purpose of this article is to achieve the compatibility equilibrium of components. For this purpose, the components compatibility was investigated in the production equipment producers.  In this research, a game has been designed in three stages with considering the available alternatives for equipment producers and service providers, in which the firms decide about compatibility before price competition in selling stages and providing services. Then, by means of static games solution with imperfect information, the game equilibrium has been exploited. The modeling results showed that the component incompatibility is the game equilibrium and the firms with monopolization incentives in providing the after sale services, produce own provided outputs under an incompatible situation. Based on results, is suggested the production equipment byers, if possible before purchase, evaluate the rate of breakdown of production equipment, and also, concurrent with purchasing the system, buy the spare parts.

This article aims to describe and explain the strategic behavior of managers and shareholders in the interactive conflict environment of joint-stock firms using the tools of game theory, specifically through signaling games. Managers, considering the quality of internal controls, engage in both deceptive and informative earnings management strategies. Shareholders then respond with strategies involving high or low capital costs and opt for either high or low-quality audit services. The findings of the research outline the theoretical conditions necessary for establishing balance in strategies such as deceptive earnings management with high capital costs and deceptive earnings management with high-quality audit services in environments characterized by weak internal controls. Additionally, it highlights the conditions required to establish equilibrium in strategies like informative earnings management with low capital costs and informative earnings management with low-quality audit services within environments boasting strong internal controls.
