Michael Veseth. Introductory Macroeconomics, Second Edition deals with national economic issues, such as unemployment, inflation, the aggregate demand-aggregate supply model of macroeconomics, government economic policy, exchange, rates, international trade, and finance.

The book examines national economic problems, economic goals, the role markets play in the economy, price control, unemployment, and inflation. By using the Phillips curve trade-off, the text notes that inflation increases the demand for labor. In the long term, according to the long-run Phillips curve, increased inflation does not actually lessen unemployment levels known as the natural unemployment rate hypothesis. The text also examines whether minimum wage laws are necessary to fight poverty, prevent exploitation or cause poverty in which the imposition of minimum wage results in lower demand for unskilled labor.

The book notes that politics and unions favor minimum wage laws. The poor, uneducated, and unskilled laborers are left out.
