Abstract This study examines the effects of the interaction of a size-dependent tax policy that exempts firms whose stated capital is at or below a certain threshold from taxation and financial frictions on firm growth and financing. Our empirical findings can be summarized as follows: First, firms with lower productivity, a positive potential tax benefit, and smaller stated capital are more likely to conduct the cash-out capital reduction to or below the threshold in response to the policy. Second, this capital reduction causes ex-post lower firm growth and fewer debt. Third, such causal effects are observed for firms with less cash flow ratios. These results indicate that the interaction between a size-dependent tax policy and financial constraints deters firm growth. Plain English Summary The interaction of a size-dependent tax policy that exempts firms whose stated capital is at or below a certain threshold from taxation and financial frictions deters firm growth. We use the introduction of the pro forma standard taxation system in Japan that exempts firms (SMEs), whose stated capital is at or below a threshold, from taxation to empirically examine how firms react to this institutional change and how such a reaction systematically affects their financing and real outcomes. We show that size-dependent tax policies can have a significant effect on firms’ growth and financing through financial constraints. It indicates that firms decide whether to obtain an SME status by considering the trade-off between a more severe borrowing constraint and a smaller tax payment. The results obtained in this study indicate that such indirect effects of a size-dependent tax policy on firm dynamics should be considered when designing the policy. Moreover, governments should understand that an institutional change in their tax systems generates a heterogeneous reaction from firms and thus has heterogeneous effects on their dynamics.

Abstract We estimate the causal effects of a tax incentive for specific productivity-enhancing equipment introduced in 2014 for Japanese small and medium-sized enterprises (SMEs). Using firm-level panel data, we find, first, that the introduction of the tax incentive did not on average increase the capital investment rate of SMEs eligible for the tax incentive possibly due to the small number of firms using the incentive. Second, despite this finding, the firms using the tax incentive increased their capital investment rate and improved labor productivity more than the comparable firms holding the stated capital close to but more than the criterion of SMEs did. Third, firms using the tax incentive did not increase capital intensity. Fourth, more financially constrained firms using the tax incentive increased their capital investment rate to a greater degree. These results show that the use of the tax incentive mitigates financial constraints in upgrading capital.

Using Japanese firm-level panel data spanning from 2000 to 2013, we estimate industry-level production functions that explicitly take into account the complementarity and substitutability between tangible and intangible capital. The estimation results show that tangible and intangible capitals are complementary in most industries although the degree of complementarity substantially varies across industries. We further find that the relation between tangible and intangible capital in the production function accounts for the relation between firm-level tangible capital and intangible capital investments. Namely, firms’ tangible investments are more strongly positively associated with intangible investments as the degree of the complementarity between the tangible and intangible assets becomes larger. These findings show the necessity to take into account the relation between the dynamics of tangible and intangible capital in terms of their complementarity for precisely understanding the mechanisms governing a firm’s growth.
