The book contains the basic classical macroeconomic models: the Solow growth model and the classical AS-AD model in the three markets of labor, goods/funds and money. The final chapter is a bridge to microfounded theory through the analysis of a two-period economy and of the underlying intertemporal choices by consumers and firms. The overall result is a less fragmented, more unified presentation of classical macroeconomic. In Mybook website are available a lot of exercises of various level of difficulty and more data about the world’s economy (today, in the last 20 years, in the last 200).
