[skyrim] what is the dragonborn's effect on society and the economy?

Every time they roll into town they flood the market with gems, leather bracers, and masterwork-quality enchanted armor. Every merchant down to the flower-seller now stocks Rings of Sneak and Carry Weight. It's a crime wave waiting to happen! Except nobody has any cash.

Massive deflation. When the Dragonborn comes, he sells so much loot and hand-crafted daggers of health absorption that the local community *runs out of gold*. In a few hours, there are only a few pieces of coin left. 

This causes deflation: The rapid fall of prices. Why? Because as gold runs out, each individual coin in the area becomes more valuable, so you can get more for each coin you spend. But since everyone knows prices are falling continually, no one wants to spend money - they all figure that if they wait, the price of what they want will get even lower.

In other words, the Dragonborn's visit causes a total economic shutdown for a while. What happens next?

The Dragonborn usually ends up buying real estate. This means the local Jarl collects almost all that gold personally, just for giving up some house last owned by a dead person. Now the Jarl has all the cash. What do they do?

They give it back to the people! This the only way to resuscitate the local economy. They buy up the Dragonborn's loot at a discount from the merchants, thereby earning a reasonable profit as jarls and also collecting most of that dangerous gear. They can reward their retainers with choice items, and the rest they gift to commoners when they die - which keeps the Nord tombs full of random loot while also temporarily removing such crazy things from the economy.

That's why so much treasure is buried underground: The economy can't handle it actually being circulated. It's most efficient to hide it every time a new tomb is built. This also happens to lure disruptive adventuring types far from civilization, where it's hoped they get killed.
