Evaluation of catch-up paths by an uncertain dynamic game model

To model the interaction of fiscal and monetary policy, a novel discrete-time, uncertain, infinite time horizon, dynamic game model is developed, where the uncertainties of expectations are modeled by unknown nonlinear but quadratically constrained deterministic functions. Cost-guaranteeing Nash strategies are defined for fiscal and monetary policy as two players. The model is suitable for comparative analysis of the development paths of catching-up economies. Specifically, we evaluate nine possible development paths for the Hungarian economy, where each path is characterised by a proxy for the debt-to-GDP ratio.

Transaction Costs: Economies of Scale, Optimum, Equilibrium and Efficiency

The aim of this article is to propose a core game theory model of transaction costs wherein it is indicated how direct costs determine the probability of loss and subsequent transaction costs. The existence of optimum is proven, and the way in which exposure influences the location of the optimum is demonstrated. The decisions are described as a two-player game and it is discussed how the transaction cost sharing rule determines whether the optimum point of transaction costs is the same as the equilibrium of the game. A game modelling dispute between actors regarding changing the share of transaction costs to be paid by each party is also presented. Requirements of efficient transaction cost sharing rules are defined, and it is posited that a solution exists which is not unique. Policy conclusions are also devised based on principles of design of institutions to influence the nature of transaction costs.
