An economic recession can result from falling employment rates triggered by a drop in investment, which cause cutbacks in consumer spending, starting a cycle of layoffs that lead to even lower employment rates.
In the above mentioned sentence what does the modifier 'which' refer to. Does it refer to 'investment' or to 'drop in investment' or to 'rates'.
Also, how to identify which part the 'which' modifier is referring to ?
Is there any general rule that we can follow regarding the usage of 'which' for these type of sentences?
In your example, the ", which" must describe "falling employment rates". (I've kept the essential modifiers "falling" and "employment" for meaning; "rates" is the only noun in that phrase.)
A ", which" modifier is a clause modifier: there is a verb inside the modifier itself. Because of this, there are two issues we must consider--placement and subject/verb (S/V) agreement.
In your example, placement would indicate that the modifier describes "investment". But investment is singular, and "cause"--the verb inside the modifier--is plural. This singular vs plural disagreement means the modifier cannot describe investment. We must find a plural noun preceding the modifier, and the only one is "rates".
If you see a ", which" (or ",where" or ", who") modifier, consider both placement and S/V agreement between the verb in the modifier and the noun you are attempting to describe. If both placement and verb agree, then you have the noun that is described. For example, consider the sentence "I teach classes at the Georgia Tech Hotel and Conference Center, which is located in midtown." Here, the placement indicates that the modifier is describing the GT Hotel and Conference Center, and since both this noun and the verb in the modifier ("is") are singular, this modifier is describing what it's touching.
In your example, since the placement and S/V relationship do not indicate the same noun. In this case, the S/V agreement takes precedence.
