   • 1974, Lawrence H. Officer, Lawrence Berk Smith, Issues in Canadian Economics, McGraw-Hill Ryerson, page 336:

     The consumption-possibilities curve illustrates the choice which must be made: more jam today means less jam tomorrow; less jam today means more jam tomorrow.

   • 1985, Phillip Crowson, Economics for Managers: A Professionals’ Guide, 3rd edition, Macmillan Press, page 26:

     A basic human characteristic is the preference for consumption today over consumption tomorrow. Jam today is always better than jam tomorrow, unless sufficient incentive is offered to forgo the immediate enjoyment of today's jam. This is not because of uncertainty about the likely receipt of tomorrow's jam, but merely a property of the passage of time.

   • 1985, Joel Mokyr, The Economics of the Industrial Revolution, Rowman & Littlefield Publishers, page 216:

     For one-period optimization, the obvious course of action to maximize consumption is to consume the whole of output by “eating up” the capital stock. The inapplicability of this tactic to an industrializing nation is transparent—it gets a lot of jam for today but leaves little for tomorrow. Jam today has therefore to be balanced against jam tomorrow.
