I have a Master's in Economics. In graduate classes, much of the work done in intro-level courses is tossed aside for more capable models that require a fair bit of calculus to understand. The easiest being the Solow growth model.
The intro courses delve into macro static models with at most 2 variables (think Keynsian Cross). In the graduate level, macro theory is taught as micro theory. While the deleterious effects of price controls still hold true at higher levels of economic reasoning, it's a multi-variate problem. With any price control, think of it as damage the rest of the people acting in the economy think of ways to route around. If a minimum wage increase takes place, perks can be cut without affecting overall employment levels as an example of how overall employment may stay the same.
