Macroeconomics
Take a shot, why do you think? Hint: just explaning the difference between positive and normative policies will be very closed to answering your question.

Economics
Draw your AS and AD graph. To lower prices and raise output, you would want the supply curve to shift outward. What government policies could do this? Take a shot.

economics
Take a shot, what do you think? Hint: I think Normative

macroeconomics
Take a shot, what do you think? Hint think short run vs long run and total GDP vs per-captia GDP.

Economic Theory
Hummm, what an opened ended question. Economists are both policy advisors and scientists. Here are a couple of quick thoughts. A scientist wants to base his finding and a advisor wants to base his recommendations on hard, reliable, and repeatable data. However, often, an advis...

econ
Generally speaking, the two advantages of excess capacity are: 1) a threat to competitors that additional production is quite possible - that the firm has the ability to engage in a price war, 2) that physical capital, frequently, cannot be adjusted in the short run. So, firms...

Math
I think it means you have not provided enough information. [-4,10] would be a single point on a graph. For an interval you would need at least two points. That said, its possible that your teacher(s) intend that [-4,10] mean something else besides a single point; what that is ...

Economics
False: profits will decrease, but by an amount less than $10M. The monopolist will cut back on production; it will produce something less than 1 million units.

macroeconomics
I'm not sure what you mean by "leakage schedule" That said, your marginal propensity to consume is .75, meaning your government spending multiplier is 1/(1-.mpc) = 1/.25 = 4. The taxation multiplier is one less than the government spending multiplier = 3. So, if ...

Economics
I believe I understand your question. And the answers are yes and yes. On your graph, the tax is represented by the area of the rectangle defined by P (paid by consumers), P (received by sellers), and the quantities 0 and Q=new equalibrium. (The difference in the two prices sh...

microeconomics
They differ in the number of competitors. A monopolist, by definition, is the one and only firm producing some good or service. Under perfect competition, we assert there are a multitude of firms producing.

economics
currency/dollar and dollar/currency are really the same thing, just recipricals of each other. To graph the demand for dollars, put number of dollars (Q) in the x-axis, put the price (P) of those dollars in terms of the other currency on the y-axis. I hope this helps.

economics
Draw a demand-supply graph for dollars. Put dollars (Q) in the x-axis, put Euros (P) on the y-axis. Demand for dollars is the willingness of people to purchase Dollars with with Euros. The supply of dollars is the willingness of people to sell their cache of dollars for Euros....

Economics
Take a shot, what do you think. Hint: GDP is the sum of P*Q for each good. Hint 2: as 2005 is the base year, use 2005 prices for 2006 productions

Economics
The demand-supply curve for what?

economics
Lets start with am international supply and demand for US dollars, expressed in terms of of some foreign currency such as Euros. The demand for US dollars comes from foreigners who want to buy US goods. An increase in the demand for US goods would lead to an increase in the de...

Macroeconomics
do you have a question?

Statistics
You have not provided enough information to answer that question. First, you need to specify an alpha for a desired confidence level (e.g., with 95% confidence, the margin of error is within 5%) Second, you have not specified what it is you are measuring. Is it a binominal (ye...

economics
I'm not sure if you are asking for help in solving a simple and specific economics problem (What happens to tax revenues in a community if they raise taxes on cigarettes?) Or a more general question involving the character of the long run demand for cigarettes in light of ...

Data analysis and statistics
Median is the middle number. First sort the numbers: I get 1,4,9,14,15,25,36. The middle (median) is 14. Mode is the most common occurance. You have two '8s', three '9s', two '10s' and one of everything else. The mode is therefore 9. Mean is the average...

economics
One reason is the ability to borrow; we can consume more domestic and foreign goods today at the expense of consuming less tomorrow. Another reason is inventory buildups. We made goods than we consumed yesterday. So today, we can consume more today than we produce today.

Economics
The tax was $8, consumers paid $4 more, producers got $4 less. With linear supply and demand curves, the results must and symetric changes, the changes in producer and consumer surplus must be the same. Change in producer surplus is also 80. Also, I have no idea how to draw a ...

Economics
As you can see, trying to produce a graph on this Jiskha is an exercise in frustration. However, based on the facts you gave me, and ASSUMING your supply and demand functions are linear, I can reconstuct your your graph and determine the changes in producer and consumer surplu...

Microeconomics
It has been 25 years since I needed to look at Cournot models. But, I remember that things got complicated in the case where the firms had different cost structures. The intuition behind the Cournot model can be found in a Nash Equilibrium. Sorry I cant be more helpful.

Economic DQ's
Take a shot. What do you get. Hint: calculating the cost of chili in 1996 and today is easy. Calculate the ratio cost today/1996. For an index, make 1996=100, today's index will have the same percentage increase as the cost to produce the chili. take it from here

Take a shot, what do you think? Think about the various types of market failures in our current health care systems; both private funded systems and public funded systems (e.g., medicare and medicaid). Also, do we have a "moral" obligation to provide basic health car...

Economics
Take a shot, what do you think? Hint: draw a graph with an elastic supply and an inelastic demand. Then shift up the supply curve representing the tax. What happens to price and the amount of revenue received by suppliers? by purchasers?

Economics-Repost of Question
As you now know, graphs and graphics on this Jiskha site is near impossible. I dont understand your graph at all. That said: Consumer surplus is represented by the AREA below the demand curve but above price. A tax would raise, vertically, the supply curve by the amount of the...

Economics
First, I disagree with your opening premise; a macroeconomic policy may well be the correct solution. The appropriate economic policy depends on the economic problems. High inflation, for example, may call for reducing the money supply (a macro solution I might add). High unem...

I suggest you work out an example. Buy $100 of stock at 50% margin means $50 comes out of the investor's pocket, the other $50 is borrowed. The stock rises to $107, the stock is sold, the loan is repaid plus interest (of amount r). So investor is left over with ($57-r). Si...

Micreoeconomics
First, I dont know what you mean by "for P B 10" or "=0 for P<10" That said, equilibrium will occur when Qd=Qs. You have the equations, simply solve for Q and then P. Hint: I get Q=500, P=40. Since there are 25 firms, Qi=500/25 = 20 b) since each firm is...

Industry supply curve is the horizontal sum of each firm's marginal cost curves. If SMC=q/4 then the supply curve will be P=Q/(4*35) = Q/140 = .007142Q Demand is P=20-.05Q At equilibrium, supply=demand, so, solve for Q and P. Hint: I get Q=350,P=2.5, which means q=10. b) w...

I think I understand your question. The answer is yes. Price and consumption are inversely related as too are interest rates and consumption.

Microeconomics-Consumer & Producer Suplus Graphs
Sorry, Im having trouble understanding whs you mean by the third area. But my advice is to keep it simple; consumer surplus is the area below demand but above price. Period. When you shift your supply/demand curves, check for 3 (and only 3) possible conditions. 1) the new cons...
