In Macroeconomics by Krugman and Berben, professors Bisanko and Braeckam introduce the general theory and concept of macroeconomics to the layman. The book contains many fully worked-out historical cases that offer a clear step-by-step pathway to aid them solve more practical numerical issues.
This book also goes into the details of various macroeconomic concepts such as demand management, price stability, monetary policy, asset price stability, price evolution, inflation, deflation and risk management. The macroeconomic concepts presented are: the theory of demand management, money management, central bank policies, risk management, exchange rates and international trade.
Unlike some previous books in this series, this one does not begin with the concept of macroeconomics, but begins with the study of certain concepts that pertain to it, namely macroeconomics and microeconomics. The book is divided into four main parts, each dealing with a different aspect of macroeconomics, which is then discussed in turn with reference to other relevant areas of economics. Part one, which looks at the measurement of macroeconomic activity, is comprised of chapters on macroeconomic concepts like equilibrium, unemployment, money and financial markets, optimal allocation, monetary policy, balance of payments and international trade.
Part two looks at the concept of supply. The book rightly says that supply is not a primary economic activity, as it is not affected by demand. Thus, the supply is treated as an abstract term in macroeconomics. The book then goes on to look at the notion of demand, with a section looking at the concept of demand determination, which it says is not as easy as it sounds. The third part looks at macroeconomic implications of oil prices, with the fourth section looking at supply-side factors that affect oil prices.
