英文摘要:
This paper describes surface-like waves of macroeconomic Credits-Loans transactions on economic space. We use agent\'s risk ratings as their coordinates and describe evolution of macro variables by transactions between agents. Aggregations of agent\'s variables with risk coordinates x on economic space define macro variables as function of x. Aggregations of transactions between agents at point x and y determine functions of two variables (x,y) on economic space. As example we study Credits transactions provided from agents at point x to agents at point y and thus amount of Loans received by agents at point y from agents at point x at moment t during time term dt. We model evolution of macro transactions by hydrodynamic-like equations. Agents fill macro domain on economic space that is bounded by minimum risk ratings of most secure and maximum risk ratings of most risky agents. Economic and financial shocks can disturb steady borders of macro domain and cause perturbations of transactions. Such disturbances can generate waves that can propagate along risk borders alike to surface waves in fluids. As example, we describe simple model interactions between two transactions by hydrodynamic like equations in a closed form. We introduce notions of \"macro accelerations\" and their potentials that establish steady state distributions of transactions on economic space. For this model in linear approximation we describe surface-like waves and show that perturbations induced by surface-like waves can exponentially grow up inside macro domain and induce macro instabilities in a low risk area. Description of possible steady state distributions of transactions and surface-like waves on economic space might be important for macro modeling and policy-making.

中文摘要:
本文描述了经济空间上宏观经济信贷交易的面波。我们以代理人的风险评级为坐标,通过代理人之间的交易来描述宏观变量的演变。经济空间上具有风险坐标x的代理人变量的聚合将宏观变量定义为x的函数。点x和y处代理人之间交易的聚合确定了经济空间上两个变量(x,y)的函数。例如,我们研究了x点代理向y点代理提供的信贷交易,以及在时间期限dt内,y点代理从t点代理收到的贷款金额。我们用类流体动力学方程来模拟宏观交易的演化。代理人填补了经济空间的宏观领域,经济空间以最安全代理人的最低风险评级和最危险代理人的最高风险评级为界限。经济和金融冲击可能会扰乱宏观领域的稳定边界,并导致交易扰动。此类扰动可产生可沿风险边界传播的波,类似于流体中的表面波。例如,我们用封闭形式的类流体动力学方程来描述两个事务之间的简单模型相互作用。我们引入了“宏观加速”的概念及其潜力,建立了经济空间上交易的稳态分布。对于线性近似下的该模型,我们描述了类面波,并表明类面波引起的扰动可以在宏观域内指数增长,并在低风险区域引起宏观不稳定性。描述经济空间上交易和表面波的可能稳态分布,对于宏观建模和决策可能很重要。
