How do Community Currencies Work?
Community currencies, in general, function as a supplement to the standing market currency. There are a variety of systems in place around the country, most of which fall into two major categories:

Individuals accept Ithaca HOURS as payment for goods and services they offer, legitimizing work that may not have been regocnized in the traditional employment market. This system also encourages new transactions and interactions between community members. Local businesses and also participate, accepting the local currency as payment for all or part of their good or service charges.
The general purpose here is to support and encourage local transactions, increasing the local capacity to gain control over it's economic life while generating new community-level interactions.
Programs using time as the community currency have a slightly different focus. Based on the Time Dollar created by Edgar Cahn and Jonothan Rowe, these programs maintain a computer system whereby individual accounts are managed. If Mary spends one hour taking Jane to the grocery store, she logs one hour on her account. She can then cash in her hour by receiving help from Jim, who might clean Mary's house.
Time Dollars allow participants to access goods and services they previously
paid for with the standard currency. Oftentimes these are goods and
services we used to rely on family and neighbors for. But as our
society has changed, the service economy has expanded to fill in these
gaps. Time Dollars are about reclaiming a sense of community by offering
our time to one another. They also serve to validate all participants'
contributions as holding equal value, regardless of the work being performed.
One hour of work is worth one Time Dollar credit. This provides the
basis for empowering the individual participants as well as building the
community's capacity to address it's needs.
Evaluation of Community Currency Initiatives?
We can analyze the logic behind community currencies and anticipate
some set of effects a community currency system might have on a locality,
or on the people who participate in it. But analysis has not gone
so far as to actually calculate the direct economic impacts of community
currency efforts. This area of study will be important if the movement
is to ever become part of the mainstream in community economic development.
