 dynamics, stochastic general equilibrium models, and classical Kenyan debate. Until recently, classical and Kenyan used very different models. Recently, each group has incorporated ideas from the other group. Kenyan economists began using DSGE models and the classical began using sticky prices and imperfect competition. So, DSGE models have become the most important tool to discuss the economy. Central banks and government agencies and academics use this tool to analyze the economy. Before that, I would like to talk about the dynamics of the world. We take into account the time dimension of economic decency. The different macroeconomics variables and how they behave over time. They are stochastic, meaning that they allow for random shocks to the economy. Finally, these models are based on microeconomic foundations, meaning that they are based on the behavior of individual economic agents and general equilibrium theory. There are three types of agents. Consumers, firms and government. These three are our major economic agents. So, we discuss the behavior of the consumer in terms of utility maximization. We discuss the profit maximization of the government fiscal and monetary policy. We discuss the microeconomics principle. For example, the consumption of aggregate consumption. Obviously, we adapt the consumption of individuals to aggregate consumption. So, how do individuals decide their consumption? From utility maximization. So, from microeconomic foundation, we develop macroeconomic variables. Generally, equilibrium theory means that we interact with all the markets. Finally, when it comes to equilibrium, we interact with all the markets. So, economists were able to reconcile aggregative models with models of microeconomic foundation. I have just explained that we talk about aggregate output and aggregate consumption. But we use microeconomic foundations to build this. Usually, we talk about this in terms of representative households. So, classical and Keynesian skills still disagree about the speed of wage and price adjustment and the role of government policies. But now speak the same language in modeling the economy. Obviously, their differences still exist. Their basic difference is that prices and wages adjust from what speed? Keynesian says that they slowly adjust and classical says that they adjust very instantly. But now, they discuss everything in a common framework, a common model. They understand everything and understand each other's point of view. So, the language is available in the same language in which we talk about ourselves. Okay, thank you.
