Who determine the price of goods and services?

Well, there are many economic agents whose influence can affect significantly prices.

First, the basic, supply and demand, if any other factors meddle with the market dynamics they will settle the price. Prices will change till supply and demand find an equilibrium. If demand is too high, prices will rise for a fixed level of product till people stop wanting the product or it gets profitable enough that new firms will want to enter the market and absorb part of those gains. The same applys for too much supply, prices will fall.

Second, is this a competitive market or is it a monopoly/oligopoly? Firms in the latter will have more market power tending to rise prices above the expected value in a competitive market, their mark-up will be higher.

Third, those firms will have suppliers themselves and get affected by regulation, taxes and many other economic forces.

Forth, what is the price elasticity of the consumers in this sector? This means, if the firm impose higher prices will demand drop fast or slow, is it an essential good (Medicine, fuel, etc.)?

Fifth, do consumers know about what they are buying? Is there assimetric information, time-inconsistent preferences?

Those are SOME of the factors, there are many other cases and scenarios, but they all share a characteristic, they are all microeconomic phenomena, if you which to know more about it I would recommend Hal Varian Microeconomics book is a good entry-level book, focused more on concepts and meanings than the math behind those economic models.

    racial conflict and discrimination has existed ever since man learned to kill with rocks and bones. these conflicts arose from disputes between territory, power, wealth, religion, or simple difference. some of the most infamous racial disputes include slavery, the holocaust, and the civil rights movement.

    these listed disputes often resulted in casualties from all sides. riots, wars, imprisonment, and lynching are all commonly associated with racial conflict on severe levels.

      however, racism is an improving issue in recent decades. people are being more accepting and welcoming of diverse populations. though, the world isn't perfect and it will take much more time, if ever, until the world is rid of racism.

well, paralell is parallel. i am providing links to .

hope this !

a series circuit is one with all the loads in a row. there is only one path for the electricity to flow. if this circuit was a string of light bulbs, and one blew out, the remaining bulbs would turn off.

unlike in series circuits, a charge in a parallel circuit encounters a single voltage drop during its path through the external circuit. the current through a given branch can be predicted using the ohm's law equation and the voltage drop across the resistor and the resistance of the resistor.

a parallel circuit has certain characteristics and basic rules: a parallel circuit has two or more paths for current to flow through. voltage is the same across each component of the parallel circuit.
