Answer:
C
Explanation:
The GDP or gross domestic product measures the market value of all goods and services produced in country in a specific period of time. This year GDP should not include the log-splitter because Sally purchased it five years ago. We should include this year purchases: new parts, gasoline, oil. Also, we should include the market value of the 2 hours she spent repairing the log-splitter if she paid someone to do it or if someone paid her to do it, because this is a service. But the problem suggests that she repaired her own log-splitter, then we should not include it this year GDP.
Answer:
b) A free market in tradable permits is typically more efficient that government regulation
Explanation:
- When companies are forced to buy rights to pollute, they are paying a cost for the pollution they create. If they pollute more, they will end paying more for that pollution. (demand of rights to pollute)
- On the other hand, companies that pollute almost nothing can sell rights to pullute saving money: this will create a benefit for companies who take care of environment. (supply of rights to pollute)
- Then, there will be a market of rights to pullute, where some companies will sell and others will buy rights to pullute. In this market, the price of rights to pollute will be determined efficiently.
- Because the production of absolutely every good or service sold in our economy implies pollution, there is a cost society is willing to pay in terms of pollution to get the goods and services it consumes.<em> For example</em>, I am willing to keep buying soda, besides I now for sure its production has certain negative effects on environment. I demand the product, therefore the company (that pollutes) has incentives to keep selling the product.
- The cost we are willing to pay to keep consuming goods will be related to the demand and supply of rights to pollute : companies whose producs are more demanded (by us!) would buy more rights to pollute when neccesary, and companies whose products are not that demanded will buy less rights to pollute, transmiting this results to prices.
- Then, pollution rights became an efficient way of assigning a price to pollution.
Valve guides are one of the components in the engine that are subjected to a hard thermal and mechanical stresses. There are 3 specific types of valve guides, and they are :
Mono-metallic Valves - Produced with the idea of hot extrusion process or stamping process;
Bi-Metallic Valves - Make as possible to use the perfect combination of materials, both for the steam and the head;
Hollow Valves - This Valve guide have a particular use that it helps to reduce the weight and also reduce the temperature. Filled with sodium, the shaker effect of the sodium means that heat can go from the valve head to the valve stem, after this the temperature reduction of between 80°C and 150°C can be achieved.
Answer:
Substitute product
Explanation:
Since Alison uses an eco-friendly Seventh Generation brand diapers which was currently unavailable in the local grocery store, she substituted with the regular Pampers diaper brand.
She substitutes her priority brand over what she could supplement it with in the time of need.
Substitute goods are those which can be replaced with a comparable product similar to the one in current use.
