'yield' is essentially 'gain' or equivalence so it depends...
You've selected Economics & Chemistry as your categories so assuming you mean Economic Yield & Chemical Yield...
Economic Yield could mean a few things but the most common would probably mean Profit (Measurement: Currency).
Chemical Yield could also mean a few things depending on context but it's probably the reaction yield or the quantity of product (Measurement: Weight).
But really it all depends on context...
In my experience, the theoretical yield is usually higher, if everything is measured accurately.
The measured amount of product.
It doesn't. The whole point in a catalyst is that the only thing it does, is speeds up the reaction. It does not change or affect it in any other way. However, factors which can change yield of reaction are temperature and pressure. For example, take the manufacture of ammonia. Pressure is measured in Atmospheres (atm) Temperature is measured in degrees celcius (oC) Companies that manufacture ammonia generally use 10 atms, and at least 450oC Increasing the pressure above around 10 atms, reduces yield. Having temperature that high, also reduces yield, but as well as the catalyst, it increases the speed of the reaction.
Percent yield = (actual yield/expected yield) x 100
# Determine the limiting reagent; # Calculate the expected yield if the reaction goes to 100% completion. # Divide the actual yield by the expected yield and multiply by 100. The result is percentage yield.

The measured amount of product.
Theoretical= calculated
This is usually referred to as the ACTUAL YIELD of that substance.
The measured of the amount of product obtained from a chemical reaction is called the yield. The yield can be further converted into a percent yield, which is the ratio of the actual yield of the experiment to the theoretical yield multiplied by 100.
It is known as the yield of a recipe which tells you how much of a product is made with the recipe you are given.
Crop productivity is the quantitative measure of crop yield in given measured area of field.

Aside from the fact that they are measured for the same reason. They are also resulting in the same outcome because they utilize the same statistics.
On the island Novaya Zemlya in the USSR above the Arctic Circle in 1961. It was called Tsar Bomba (King of bombs) and had a yield of 52 MTons to 58 MTons, depending on how it was measured. The design (AN602) had a potential yield of 100 MTons, if they had wanted to go all the way.
actual yield multiply by 100 = % yield theoretical yield
