Answer:
GDP grew by $2,200
Explanation:
G<em>ross domestic product (GDP) which is the total market value of all the final goods and services produced in a country over a given period of time. The GDP can be calculated using the value added approach.</em>
Here the GPD figure is ascertained by summing the amount of additional value created by each factor of production at each stage of the production process of the final product.
<em>Only the values added are summed, the cost of the inputs or intermediate goods are not included</em>
<em>In this question, the final value of $2200 represents the amount by which the GDP has increased in the period. This also can be verified using the value-added approach as follows</em>
                                                    Value added($)
 Gold miner   -                                   600
Mining company : 1000 -600 =      400
Jewerlry maker  :1600 - 1000 =      600
Departmental store :2200 -1600 = <u>600</u>
Total value added                           <u>2,200</u>
 
        
             
        
        
        
Answer:
they have an opportunity to exploit network effects and positive feedback loops 
Explanation:
The first mover advantage refers to competitive advantages that can be achieved by a firm that first enters a market or launches a new product first. E.g. Volkswagen has a first mover advantage in China because it was the first foreign car manufacturer to successfully a car factory there. Another type of first mover advantage would be the ones obtained by Apple for launching the first smartphone. 
Network effects refers to a good or service becoming more valuable because more people purchase or use them, e.g. social media apps.  
Positive feedback loops occurs when a company's output is used as a positive input in the productive system, e.g. when a company uses information gathered by customer service (CRM) to improve the products or services it offers.

Explanation:
Diversification in a portfolio refers to spreading investments in such a way so as to minimize risk.
The correlation coefficient r between two securities signifies how return from one security is related with another security. For example, two securities of the same sector may move in the same direction or positively correlated as in if price of one rises, the price of other rises too maybe not by the same margin. 
In case of a negative correlation, the security returns move in opposite directions i.e the securities are least related to one another.
Maximum diversification is achieved when r is equal to -1 i.e the two stocks move in opposite direction by the same magnitude.
