This essay offers an alternative way to look at macroeconomics. The current standard approach uses aggregate supply and aggregate demand (AS-AD). I call the alternative approach patterns of sustainable specialization and trade (PSST). The PSST approach combines many old and new strands in economics. It suggests that the economy is a highly complex system that is constantly adapting to new circumstances, especially opportunities created by technological innovation. We can view employment fluctuations as a reflection of the difficulty that markets sometimes have in making the necessary adjustments, so that for a period of time some workers have extremely low marginal revenue product and as a result become unemployed.
