||In 1993, the debate heated up in Canada about the North American Free Trade Agreement (NAFTA), which proposed to reduce barriers to trade (such as taxes on, or limits to, imports) among Canada, the United States, and Mexico. Some people strongly opposed the agreement, arguing that an influx of foreign goods under NAFTA would disrupt the Canadian economy, harm domestic industries, and throw Canadian workers out of work. How might a classical economist respond to these concerns? Would you expect a Keynesian economist to be more or less sympathetic to these concerns than the classical economist? Why?
