I scratched my head for a bit thinking you were referring to me selling you my beer and you selling me yours...
Any economists in our midst?
I think the answer is yes. There is huge potential in the market and with good solid product, should do well even in the current slump.
If you can switch the Irish consumer to buying local fare(beer, food, whatever), that keeps money circulating and promotes jobs and will impact positively on the economy.
If what you buy (goods and services)is from local producers and not imported, this again contributes to the local economy.
And obviously, if you export your product, that brings money into the economy.
