Participant mturk_agent_2's preferences:
value2issue: Low: Food
Medium: Firewood
High: Water
value2reason: Low: Food is pretty important as well, but if I were to run out, I'd hope I'd be able to find some in the environment. Although a hunter, I am not. 
Medium: Firewood is important. Not as important as the water, but in this setting allows for both cooking and keeping warm. 
High: Water is one of the few things you cannot live without. And there is no substitute 

Negotiation dialogue:
mturk_agent_1: Who is willing to cooperate in a consensual offer so that we can all get fruitful dividends😡

mturk_agent_2: 😮 What is your offer then? 

mturk_agent_1: 2 of water, plus 2 of food and 0 of firewood

mturk_agent_2: That doesn't seem totally fair. How about I take 2 water instead? 

mturk_agent_1: I would give you 2 water in exchange for 3 food and 1 firewood

mturk_agent_2: Hm. Getting warmer. What do you need the most of? 

mturk_agent_1: I need more water than the other options, you can keep 2 food and 2 firewood but 1 water

mturk_agent_2: I also feel that water is the most important. How about I take all 3 water, and you can take 2 firewood, and 2 foods?

mturk_agent_1: I think the fairest thing would be that you keep 1 water, 2 food, 2 firewood

mturk_agent_2: How about I take 2 water, 2 firewood, and 2 food, and then you take the rest

mturk_agent_1: Let's stay like this, 2 of water, 1 of food, 1 of firewood and you take the rest

mturk_agent_2: I really need the water more than the rest of that stuff. I'll take 2 waters, 1 food, and 1 firewood. 

mturk_agent_1: We close the deal if I drink 1 water, 2 meals, and 3 firewood

mturk_agent_2: Give me just 1 firewood, and we'll have a deal

mturk_agent_1: We have a deal

mturk_agent_2: Submit-Deal

mturk_agent_1: Accept-Deal
