General equilibrium models help us understand how different parts of the economy affect each other. Researchers in Chile have created models to study how prices and quantities are determined in various economic situations. These models can be used to analyze things like international trade, public finance, and environmental issues. The research in this book shows how these models can be used to predict the effects of economic policies in Chile and beyond. By combining real-world data with theoretical ideas, the researchers can see where the models work well and where they need improvement. Overall, this book offers new insights into how general equilibrium models can help us understand and make better economic decisions.
