Ace your homework & exams now with Quizwiz!

Spillover benefits

Additional benefits to society not captured by the market demand curve from the production of a good, result in a price that is too high and a market quantity that is too low. Resources are underallocated to the production of this good. This typically results in government subsidies that raises demand.

Despite perceptions to the contrary, the proportion of Canadians moving to the US is much lower than in previous decades. He suggests that Canadian economic welfare compares well with other nations, and in particular the US, which illustrates how small economies can stand up against larger economies in today's global economy. Satisfaction with our health care system is relatively high by international standards. Canada has been relatively successful at educating its workforce, though there are some problems in the area of knowledge production (ie. research). Canada has high levels of social capital, which refers to levels of mutual trust found in society.

Market power

Describe how the resource market operates if a business is a product price maker and a resource price taker.

This is the minimum short run average cost at every output value. This curve is saucer shaped because of various ranges of return to scale. It features an initial range of increasing returns to scale, then a period of constant returns to scale, and ends with a period of decreasing returns to scale. Essentially, a small company can expand in order to become more efficient, they eventually reach peak efficiency and invest more capital in order to grow their existing operations, and in the end, they become limited by outside factors and more investment leads to decreasing returns.

Describe surplus in a perfectly competitive market.

The contemporary economic transformation of China began in the 1970s with growth-enhancing reforms in its agricultural sector. In the 1980s, this growth spread to other sectors, thanks to reforms allowing state-owned producers to keep some of their profits. After 1990, private companies became common, causing a further increase in annual growth. By the late 2000s, this growth meant that China's economy was five times larger than in 1978.

Describe the Economic Transition of China

Reforms during the early 1990s freed private businesses in key sectors of India's economy. High growth rates appeared first in services, before being extended to manufacturing. India's annual rates of economic growth now average about 8% - just a little less than the 10% rates found in China's economy.

Describe the circular flow Diagram.

Marginal productivity theory is not always applicable to other resources. It works for labor and natural resources because these resources are measured inn standardized units, however, it is harder to calculate the marginal revenue product for capital goods, because one investment project differs from another.

Describe the demand for resources other than labor in the resource market.

If tech increases, complementary resource demand increases while substitute resource demand decreases.

Describe the effects of technological advancements on resource demand.

An import quota has the same effect as a tariff, except that the increase in government revenues is replaced by an increase in the price of foreign imports

Describe the impact of an import quota on a perfectly competitive market

A tariff decreases consumption and foreign imports, while it increases domestic production and government revenues

Describe the impact of tariffs on a perfectly competitive market

Describe the results of a price change in terms of total revenue for elastic, inelastic, and unit-elastic demand curves.

Average revenue is the same as their downward sloping demand curve. Marginal revenue is below their demand curve because as they produce more, their demand curve (average revenue) falls.

Describe the revenue conditions for a monopolist.

- Average revenue equals price so that a perfect competitors average revenue curve is also its business' demand curve. - Average revenue/Price is constant so that AR=MR in perfect competition.

Describe the revenue conditions for a perfect competitor.

Average revenue is equal to the downward sloping demand curve. Marginal revenue is below the demand curve (AR) because demand falls as quantity increases.

Describe the revenue conditions of a monopolistic competitor.

In the short run, a monopolistic competitor may make a profit or a loss. In the long run, they break even.

Average cost

Either total cost divided by total product or average fixed cost + average variable cost.

She believed that growth came from people who produce previously imported items. Her theory essentially states that long term growth comes from fostering vigorous import replacing cities within its borders like what has been done by South Korea, Japan, and China. In her mid career, she extended her theory to devise a model of social and economic ethics with diversity as the key. - Societies thrive only as long as the rules that underlie commerce and politics remain distinct. - Businesspeople need to tout honesty, initiative and inventiveness, recognize the benefits of efficiency, voluntary contracts, know when to collaborate and compete, and understand the costs of ostentatious consumption and pessimism about the future. Rulers in contrast must honor loyalty, discipline and respect for hierarchy. If business people act like rulers or vice versa, monstrous hybrids are created. For example, the recent mania for corporate mergers and acquisitions, which is seen as one of the main causes for the 2008 financial crisis.

Explain Jacobs' economic beliefs

Rent controls are an example of a price ceiling. They keep down prices of controlled rental accommodation. Some (especially middle-class) tenants win from these controls. Other (especially poorer) tenants lose from these controls.

Explain Renting price supports.

The demand for Canadian dollars is the relationship between the price of a Canadian dollar and the quantity demanded in exchange for another currency (e.g. the U.S. dollar). The demand curve's negative slope is determined by foreign export buyers, since the higher Canadian $ means that Americans find Canadian products more expensive and so they buy fewer of them.

Explain the Demand of Canadian Dollars

The supply of Canadian dollars is the relationship between the price of a Canadian dollar and the quantity supplied in exchange for another currency (e.g. the U.S. dollar). The supply curve's positive slope is determined by Canadian import buyers, since a higher Canadian $ means that Canadians find American products cheaper and so they buy more of them.
