On page 2, I'm using "said" here as an alternative to repeating the phrase "low income households." Although "said" is most commonly used as the past tense of the verb "say," it can also be used to reference something previously written. It is the equivalent to saying "...thus providing financial planners, educators, and policy makers with insights to improve the aforementioned households' financial decisions." Basically, I'm using "said" as an adjective to describe the households rather than as a past tense verb. This is grammatically correct. 

On page 3, I understood your use of "household save" to be an economic term, because you immediately followed it by the term "dissave." That being the case, the terms act as nouns (the same way you would use the term "household well-being"). If this is a mistake and they are not economic terms, the sentence would be correct as follows:  "Households save when income is high, and lose when income is low."

On page 10, I removed that sentence because you introduced a point in the first part of the sentence that you did not address at the end of it. When you say, "Households having debt less than one the value of their total assets could secure their solvency status easily," this implies that you will present a solution for insolvent households to secure their financial stability. However, you misused the term "thus" by bringing up the 1.0 ratio for insolvency.  Because you highlight the debt-to-assets ratio in the very next sentence, the previous sentence was both confusing and unnecessary. 

For page 12, another way you might phrase that sentence is: "Table 3 presents the differences between meeting each financial guideline, as delineated by differing poverty levels."

And on page 17, the structure of this sentence (while complicated) is correct. If you break the sentence down you can see that the gerund (v-ing) form of "monitor" is correct. Think of it like this: "Households can more objectively assess their own financial resources and goals, thus monitoring financial stability more consciously." Hopefully that makes more sense.
