This dissertation explores how cities achieve fiscal sustainability—the financial capacity to consistently meet basic public service responsibilities regardless of economic conditions. Two research questions arise from the interplay between the local economy and fiscal sustainability. First, what management tools do cities use to achieve fiscal sustainability given that economic conditions are largely outside their control? Second, what explains the variation among cities in the financial management tools used to achieve fiscal sustainability? The financial management tools of interest in this study are revenue diversity and the size of the fund balance. It is conjectured that financial management tools interact with each other prompting the tools to function as policy substitutes for each other. Cities achieve fiscal sustainability by strategically choosing budget-balancing tools appropriate to their economic conditions. The study utilizes a cross-state comparison from 351 Massachusetts municipal governments using panel data from 2000 to 2009 and 993 New York municipal governments using panel data from 2001 to 2010. Using theories of fiscal sustainability and revenue diversification, several models are proposed that test the interactive effects of fund balance size and revenue diversity on fiscal sustainability. The results from the empirical analyses show that cities use various financial management tools to stabilize spending during economic downturns. Cities pursue strategies that help maintain fiscal sustainability. Furthermore, it is discovered that interaction of fund balance and revenue diversity on municipal expenditures is stronger as the level of revenue diversity decreases. This interaction has a large effect during periods of economic downturns as compared to periods of economic growth.

This dissertation examines the effects of tax and expenditure limitations (TELs) stringency and its interaction with revenue diversity and the council-manager form of government on municipal general fund expenditure. TELs are explicit rules that states impose to reduce local government spending. TELs stringency varies from state to state, leading to difficulties in assessing their impact across the nation. This dissertation proposes a new means for measuring the stringency of TELs imposed on local governments. Factor analysis is utilized, and then factor scores are calculated to identify degrees of TELs stringency. This study contends that higher levels of TELs stringency are associated with lower local government spending. However, the effectiveness of TELs is dependent on revenue diversity and the form of government. This study suggests that both revenue diversity and the council-manager form of government mitigate the impacts of TELs stringency on local government spending. Panel data from 2007 to 2011 from 1,508 municipalities are utilized. This study finds that higher levels of TELs stringency are associated with lower levels of municipal general fund expenditures per capita. However, TELs stringency is effective only when revenue diversity is low and when cities have a form of government other than council-manager. These results are generally consistent with the theory presented in this dissertation.
