When using verbs of movement it is important to know whether they are :

• transitive — needing an object (shown in the dictionary with a "T")
  
• intransitive — used without an object (shown in the dictionary with an "I").

So, the following verbs are transitive and need an object:

cut, reduce, raise, lower

We cut the budget.
The banks have raised their interest rates twice this year.
The company reduced the number of employees.

After an intransitive verb we cannot put a direct object:

Our turnover rose last year, but our profits dropped.

The following words are intransitive:

rise, grow, go up/down, be up/down, fall, decline, collapse, slump

Costs went down/ fell/ declined.

Many verbs can be used both with and without objects. The following words are both, transitive and intransitive:

increase, decrease, extend, expand, drop
