Social capital is considered to be closely related with trust and trustworthiness among the people living in a community. In order to empirically capture the impacts of social capital on public policies, trust is usually used as a proxy variable of social capital. Standard methodology for measuring trust involves "Investment Game". However, the results of "Investment Game" are not necessarily equal to true trust. The results might be affected by other preferences, such as risk preference and altruism. This paper aims to test whether the results of "Investment Game" are affected by risk preference and altruism by using the data from Rural Java where social capital has been accumulated over a considerable period of time and solidarity among village people is considered to be relatively strong. By conducting econometric analysis, we found that risk preference measured by "Risk Game" and altruism measured by "Dictator Game" affect the measures of trust obtained by "Investment Game". In addition, we also found that these impacts are stronger for the case of persons who have known each other rather than the case of anonymous persons.
