Document Summary

1930s unemployment was a major issue due to the great depression. International trade is a source of economic growth as it helps you to specialize. Printing more money is bad as printing more money leads to inflation. Short run (less than a year) trade off between inflation and unemployment. Prices are sticky as there are no choices. Scarcity: limited resources therefore you must make a choice. Unemployment is rising in america macro. Unemployment is rising in waterloo micro. Benefit is higher than cost: you will take that decision. When you think in terms of marginal benefit, marginal cost. Negative sign shows there is an inverse relationship. 2y = not a normal good, demand is decreasing. Demand is negatively sloping, supply is positively sloping. Market is a good way to allocate resources as you can see market benefit and cost. The point where they are equal, you can allocate the resources there. Invisible hand private interest maximizes social interest.
