The book covers the core topics of seven different but interrelated areas of Economics. Students will find the title purposive as all the important topics are covered in this single volume. It covers some new or non-traditional topics in key areas of Economics, such as the characteristic theory of demand, new frontiers of macroeconomics with key focus on the rational expectations hypothesis, central bank independence, inflation targeting, staggering of wages and prices, some new theories of international trade, the asset approach to exchange rate determination, the convergence hypothesis, endogenous growth theory and new theories of unemployment. There is also a detailed discussion of Prof. Amartya Sen’s contribution to Economics. This is likely to enrich the title further.
