Economist: If minimum wage levels are low, employers have a greater incentive to hire more workers than to buy productivity-enhancing new technology.
Conclusion
Raising our min wage levels would improve overall economic health more than the hiring cutbacks that could result from raising it.
Evidence
When min wage levels are low (like now), employers would rather hire more people than buy expensive technology that would improve productivity. By hiring workers (who are less productive than that fancy new tech), productivity falls off, and productivity is connected to higher average living standards. Meanwhile, high min wage levels results in higher productivity.
Evaluation
Since this is a Comparison between a world in which we have low min wage vs. higher min wage, we are interested in everything that relates to overall economic health in each of those two worlds.
The author needs there to be more to gain than there is to lose, when we raise the min wage. The current tradeoffs we know about are that with a higher min wage, we would have higher productivity but possibly some people would lose their jobs.
Goal
We want an answer to tell us that .
Or we want any other factor we haven't talked about yet that gets better in a world with higher minimum wage levels (a factor that relates to better overall economic health)
