Privet,

I am an economist and I would like a Russian Native to help me translate the following five expressions.
The expressions are just examples, what I am concerned about is the use of the words: to be increased, to be decreased, to increase, to decrease, go up, go down, raise, rise:

1. In the last one year inflation increased by 10%.
2. Unemployment this year decreased by 5% in comparison with the level of unemployment two year ago.
3. The government decided to increase taxes.
4. The central bank decided to decrease the interest rates.
5. Prices went up dramatically in the last semester.
6. The company decided to raise the salaries by an average of 5%.
7. Prices are continuously rising since 2000.
