I recently spoke with George Mason University Law Professor David Schleicher about his research on land use law and economics. Here is our conversation including links to some of his academic articles that have earned a lot of attention in the land use blogosphere. Emily: What are some the costs of land use restrictions? Talk about agglomeration economies and how these relate to development restrictions. David: This is a huge area of research that spans back to Alfred Marshall looking at why cities exist in the first place. It comes up with explanations for why people are willing to pay increased rents to live downtown. These include lower transportation costs for goods, which was a major driver of urbanization for much of American history. Today this is a small driver of urbanization because the costs of internal shipping have fallen so dramatically. Now an important advantage of urbanization is market size. You can see this in all different markets. Restaurant rows are a great example of this. When you go to one of these rows where there are a lot of restaurants and bars, you have insurance that if one place you go is bad, you know you have other options nearby. The last category of agglomeration benefits is learning, or information spillovers. We see this in cluster economies like Silicon Valley where people at different firms learn from each other. As Marshall explained, “The mysteries of the trade become no mysteries, but are as it were in the air.” Wage growth is faster in urban areas than in rural areas, and this comes from this learning process. In the aggregate, if you keep people out of dense cities, you will decrease national productivity. Emily: In your paper City Unplanning, you propose a tool called Tax Increment Local Transfers (TILTs) that would compensate property owners for allowing more development […]
