In this paper, we estimate accelerator models to assess the responsiveness of industry investments to changes in tax rates and incentives. The analysis uses data from the 2009 and 2010 Annual Survey of Philippine Businesses and Industry covering 27,575 and 29,271 firms, respectively, spread over 942 industry sub-classes. This data set is supplemented by administrative data on fiscal incentives.  Our results show that tax rates and incentives can explain inter-industry variations in investment levels. We find that the investment-tax and investment-subsidy relationships are non-linear: increased taxes or reduced incentives predict lower investments only for industry groups that already have previous investments.
