Answer: cost ratio
Explanation: The terms of trade must be higher (graphically to the right) of a nation's own production cost ratio. The production cost ratio allows small-scale manufacturers to determine their cost more accurately as well as control known cost parameters and is a method that can be adapted and applied to any business.
In a multi-product manufacturing firm, the production cost ratio is necessary for accurate compilation and allocation of production costs to each category of product especially when both the Production Time and the Production Runs are not the same and/or when fixed labor, overhead and other costs are drawn from the same pool. When the ratio is not applied results in a skewed allocation of production costs. This in turn can affect the business as it becomes difficult to ascertain the products whose production are more profitable to the business.

Answer: Floating exchange rate
Explanation: The floating exchange rate is a mechanism under which a country's exchange prices are set by the supply and demand-based foreign exchange market compared to other currencies. It compares with a fixed exchange rate, wherein the government decides the rate completely or mainly.
Floating currency regimes mean that lengthy-term currency price movements represent relative economic power and country-to-country rate of interest differences.
A currency that is too high or low may have a negative impact on the country's economy, impacting trade and debt-paying efficiency. The state or banking system would try to take action to bring their currencies towards a more desirable level.
