An economic model is a theoretical construct that represents a process by a number of variables and a set of quantitative or logical relationships between them – to determine what might happen in different scenarios or at a future date. Steps in CGE modeling 1. define the issue to be studied 2. construct a consistent mathematical model 3. data collection – construct the benchmark that will be used for calibration 4. code the model 5. replicate the benchmark -- consistency 6. conduct policy experiments 7. analysis of results – compare the counterfactual solution with the Environmental economics requires a transnational approach.

This chapter introduces the macroeconomic model of aggregate supply and aggregate demand, how the two interact to reach a macroeconomic equilibrium, and how shifts in aggregate demand or aggregate supply will affect that equilibrium. Economists divide the factors of production into four categories: land, labor, capital, and entrepreneurship. Incorporating experience, however, often means it’s impossible to untangle the effect of specific shocks or predict the impact of a policy change because the underlying equations do not explicitly account for changes in agent behavior. These models estimated the relations between different macroeconomic variables using (mostly linear) time series analysis. In order to simply model how humans attempt to make this possible, we need a basic behavioral assumption. An economic model is a hypothetical construct that embodies economic procedures using a set of variables in logical and/or quantitative correlations. In this chapter, we will be working with a model of a highly idealized form of competition called “perfect” by economists. Business model changes and green construction processes.
