Suppose that scientists have discovered that the production of honey has a very significant positive externality. The main input into honey production, honey bees, are most effective when there are orchards nearby. The bees gather nectar from the orchards and simultaneously pollinate the orchard. This pollination is very valuable to the orchard. However, honey firms (beekeepers) are not compensated for this positive impact on orchards. This positive externality means that the true marginal social value of producing honey is different...

When you rub the balloon through your hair, invisible electrons (with a negative charge) build up on the surface of the balloon. This is called static electricity, which means “non-moving electricity” The electrons have the power to pull very light objects (with a positive charge) toward them – like the soda can. 1) Scientists were able to create electric charge only on nonmetallic materials and never on metals. Please explain why? 2) How much water can you put in the...
