Land rents and prices rise at a faster rate than general economic growth, because of two unavoidable facts:
- Land is fixed in supply.
- Land is needed for all production.
When sufficient numbers of workers and capitalists cannot afford to produce at the higher rents brought about by growth and speculation, production begins to stop.
Let us examine some of the implications of this fact for modern economies:
New Construction is Limited. If builders must pay too much for building sites, it takes from their profit by raising their costs. Their profit on investing in the building itself is what stimulates investing, which in turn is what makes jobs and incomes.
Business Costs Go Up. Businesses that rent their premises also get squeezed by rising rents. Here's an example: A merchant goes into a new shopping center with a long term lease. His rent is often too high, but he pays it to hold his position for the later term when he hopes the rent will be a bargain. Landlords writing long-term leases get used to this, and hold out for high rentals.
Nonproductive Investments Become More Profitable than Productive Ones. Those who already own land that they might improve are squeezed, by the higher opportunity cost of the land. They have the option of selling the land to a speculator.... Landowners will "site-sit" and wait, if they believe future development will be much more gainful than development for the current market. When the workaday facts of today begin looking dull and prosaic next to the gleaming expectations of tomorrow, look out.
Banking and Credit is Destabilized. Builders needing land borrow to buy it, even though the price is too high, gambling that future rises in rents will let them repay the loan. If these rent rises fail to happen, they go bankrupt. Their buildings are not destroyed, but the capital they used to build on them was misdirected, so much of it is economically lost: the buildings lose their market value.

Please answer the following questions:
All right, now we're getting serious. We've made a commitment to growth, and we've decided to keep $2 worth of capital on hand for ever dollar of sales. We have to invest $10 every quarter just to keep our equipment from breaking down: that is our depreciation rate. This exercise illustrates how the accelerator principle contributes to business-cycle trends.
