This study explores whether bridging and bonding social capital differ in their impacts on government performance at the local level and the extent to which these impacts vary between localities exhibiting differing socioeconomic resources. The study is based on an analysis of 256 local authorities in Israel. The findings show that bridging and bonding social capital do differ in their respective effects on government performance and that the nature of the relationship of each type of capital with government performance varies by the community's socioeconomic profile. Poor communities with high densities of bridging social capital were characterized by lower deficits as a percentage of total municipal budgets, more accurate expenditure forecasts and greater spending on services per capita.
