This paper will focus on the impacts of negative interest rate implementations in five areas. To this day, there have only been a handful of areas that have had their central banks lower the interbank interest rate to below zero, thus breaking through the zero‐lower bound theory in economics. The areas studied here are Japan, Switzerland, Europe, Denmark, and Sweden. All but Japan lowered the interest rates below zero on reserve funds in their respective central banks while Japan lowered the rate only for the amounts excess of reserves. The goal of this survey article is to explain why these areas decided to implement such an unorthodox policy and determine what implications these policies have on the general economy of the area and the banks within.

In this article, we focus on the potential impacts of switching to a territorial tax system in the US. Under the worldwide tax system the US used over the years, income is included in the firm's taxable income, but their foreign income taxes paid can be claimed as deductions or credit to avoid double taxation With a territorial tax system approach, firms would only be paying taxes on the portion of their income being made in their home country. We focus on different studies that analyze the ways in which the US has moved towards a territorial tax system over the years. We also use studies done on the UK and Japan, G-7 nations that have switched to a complete territorial tax system in recent years, to compare their motives and outcomes to what would potentially happen in the US.
