Labor-dependent capital income taxation

Capital taxation which is negatively correlated with labor supply is proposed. This paper uses a life-cycle model of heterogeneous agents that face idiosyncratic productivity shocks and shows that the tax scheme provides a strong work incentive when households possess large assets and high productivity later in the life-cycle, when they otherwise would work less. The system also adds to the saving motive of prime-age households and raises aggregate capital. The increased economic activities expand the tax base and the revenue neutral reform results in a lower average tax rate. The negative cross-dependence generates a sizable welfare gain in the long-run relative to the tax system that treats labor and capital income separately as a tax base. The reform, however, can hurt the elderly during the transition with a high marginal tax on their capital income.     

Human capital and optimal positive taxation of capital income

This paper analyzes optimal linear and non-linear taxes on capital and labor incomes in a life-cycle model of human capital investment, financial savings, and labor supply with heterogenous individuals. A dual income tax with a positive marginal tax rate on not only labor income but also capital income is optimal. The positive tax on capital income serves to alleviate the distortions of the labor tax on human capital accumulation. The optimal marginal tax rate on capital income is lower than that on labor income if savings are elastic compared to investment in human capital, substitution between verifiable and non-verifiable inputs in human capital formation is difficult, and most investments in human capital are verifiable so that education subsidies can directly reduce the tax wedge on learning. Numerical calculations suggest that the optimal marginal tax rate on capital income is substantial.     

Uninsurable investment risks and capital income taxation

This paper studies the capital accumulation and welfare implications of reducing capital income taxation in a general equilibrium economy with uninsurable investment risks. It has been shown that, with uninsurable investment risks, under-accumulation of capital may result compared to the complete markets economy. We show that reducing somewhat the capital income tax rate increases the capital stock and leads to a welfare gain. The complete elimination of the capital income tax, however, is not necessarily welfare improving.     

Assessing the international spillover effects of capital income taxation

Changes in capital taxes by one economy spill onto other economies with internationally mobile capital. We evaluate these impacts using a two-region, intertemporal general equilibrium model. The foreign economy's unilateral reduction in corporate income taxation has positive but small effects on U.S. welfare. In contrast, unilateral reductions in personal income taxation impose large negative spillovers. The differences result from CIT being source-based and PIT residence-based. The CIT cut reduces tax burdens to U.S. residents who invest abroad, while the PIT cut reduces foreigners' tax burdens only. Through general equilibrium adjustments neglected in simpler models, the PIT cut lowers U.S. residents' welfare.     

Financial literacy,financial development,and leverage of small firms

This study examines the relationship between financial literacy and the leverage of small firms, specifically of the legal forms, sole proprietorships, and partnerships. Using a cross-section of 73,302 firms in 22 countries, we find that the leverage of small firms is negatively associated with financial literacy. Further, we explore the role of financial development, bankruptcy and transaction costs, and information asymmetry, in moderating the relationship. We find that the negative relationship is less pronounced in countries with lower financial development, high bankruptcy and transaction costs, and high information asymmetry environments, respectively. We contribute to the understanding of small firms' leverage and the literature on financial literacy, SMEs, finance, and entrepreneurship. This study offers policy implications for economies that promote SMEs for entrepreneurship training and development.     

Policy uncertainty and the capital shortfall of global financial firms

This paper examines how economic policy uncertainty affects financial firms' capital shortages in the event of a new crisis. By employing a global economic policy uncertainty index, we show that an increase in policy uncertainty leads to future capital shortfall increases in the event of a severe market decline. This effect of policy uncertainty is of a similar magnitude for all firms across all regions and sectors, albeit with a few exceptions. As expected, well-capitalized financial firms are less affected. Our findings have important implications for policymakers and politicians, since if their response during a severe market decline is not timely and decisive, the delay will come at a cost. Further, in terms of the implications for firms' managers, we show that during periods of elevated policy uncertainty and a severe market downturn, firms will face additional, unexpected capital requirements.     

Second-best income taxation and education policy with endogenous human capital and borrowing constraints

We formulate a two-period life cycle model of saving, labor supply, and human capital investment when individuals differ in their ability and initial wealth. Borrowing constraints result in sub-optimal choices for consumption and investments in human capital. We analyze optimal linear income taxes and education subsidies. The optimal income tax is shown to be positive—even in the absence of any redistributional concerns. A redistributive income tax relaxes borrowing constraints by redistributing resources from the unconstrained to the borrowing constrained stages of the life cycle. The income tax thus alleviates preexisting non-tax distortions in the capital market. Human capital is subsidized on a net basis in the absence of redistributional concerns. Education subsidies help to relax credit constraints and to reduce distortions from explicit and implicit taxes on human capital formation. When redistributional concerns are present, education is subsidized more if this helps to alleviate distortions on labor supply, but is subsidized less if education subsidies have a very regressive incidence. Simulations demonstrate that optimal income taxes are substantially higher when credit constraints are present. Education is generally subsidized on a net basis, and the more so if credit constraints are more severe.     

International tax arbitrage,financial parity conditions and preferential capital gains taxation

Using a finite-horizon general equilibrium model with uncertainty and money, we characterize situations where tax arbitrage opportunities may arise for international portfolio investors in an economy with heterogeneous capital income taxation when interest income and capital gains/losses are taxed differentially for some agents. We derive tax-modified uncovered interest parity conditions, Fisher conditions and forward prices similar to the no-tax ones, but augmented by tax-induced ‘risk-premium’ terms; covered interest parity and Fisher conditions remain unaffected by the introduction of capital income taxes as we bound tax-based arbitrage without restricting arbitrage per se.     

The relationship between operating leverage and financial leverage

We model the relationship between operating and financial leverage. When operating leverage is exogenously specified, financial leverage is a monotonically decreasing function of operating leverage. When financial leverage is exogenously specified, operating leverage is initially increasing and subsequently decreasing in financial leverage. Finally, when both operating and financial leverage are chosen by the firm, they can be positively related, negatively related or unrelated, depending on which underlying parameter is driving the changes. Thus, operating leverage and financial leverage do not always behave as substitutes, as argued in the traditional literature. The relationship is complex, possibly non-monotonic and dependent on the circumstances; empirical tests need to take this reality into account.     

Employee representation and financial leverage

We analyze how direct employee voice affects financial leverage. German law mandates that firms’ supervisory boards consist of an equal number of employees’ and owners’ representatives. This requirement, however, applies only to firms with more than two thousand domestic employees. We exploit this discontinuity and the law’s introduction in 1976 for identification and find that direct employee power increases financial leverage. This is explained by a supply side effect: as banks’ interests are similar to those of employees, higher employee power reduces agency conflicts with debt providers, leading to better financing conditions. These findings reveal a novel mechanism of direct employee influence.     

Operating leverage,financial leverage,and equity risk

The analysis investigates the combined leverage effect of a fixed capacity decision (fixed cost) plus debt on the risk of equity returns. It is argued that the traditional DOL-DFL calculation is incorrect. A correct calculation is given, using the fact that the capacity decision is endogenous to the firm's decision process. The analysis reveals that the capacity decision partially offsets the effect on equity risk of increasing business risk or debt. However, this ability is lost at high levels of debt.     

Optimal income taxation and migration

We tackle the issue of optimal dynamic taxation of capital income in an economy with disconnection as in Weil (J Public Econ 38:183–198, 1989), generated by migration and intra-family altruism. We show that, when the government aims at correcting such a disconnection using time-varying weights in the social welfare function, then there is room for nonzero capital income taxation, both in the short and in the long run.     

Institutional quality and capital taxation

We describe the preferred taxation regime in a small economy with uncertain institutional quality. We obtain that a preferential taxation regime in which taxes can be matched to the mobility of the tax base may be worse off than a non-preferential taxation regime in which taxes are constant across bases with distinct mobility. Since the small economy takes foreign taxes as given, our result is not driven by a downward pressure on revenues caused by unconstrained tax competition. It is instead related to the ability of a non-preferential taxation regime to credibly convey information about the institutional quality of the small economy. We present some empirical evidence which corroborates our results.     

Housing policy and the progressivity of income taxation

Most countries have tax provisions and subsidies to promote homeownership. These provisions generate an asymmetry in the tax treatment of owner- and rental-occupied housing, which affects the incentives to supply tenant-occupied housing. This paper analyzes the quantitative importance of the interaction of these provisions with the progressivity of income taxation in the context of an overlapping generations model with housing and rental markets. The model replicates the key facts observed in the economy, as well as distributional patterns of ownership, house size, and landlord behavior. The model suggests that the progressivity of income taxation can amplify or mitigate the effects of the asymmetries with important implications for housing tenure, housing consumption, portfolio reallocations, and welfare that differ from those reported in the literature.     

A two-part fractional regression model for the financial leverage decisions of micro,small, medium and large firms

In this paper we examine the following two hypotheses, which traditional theories of capital structure are relatively silent about: (i) the determinants of financial leverage decisions are different for micro, small, medium and large firms; and (ii) the factors that determine whether or not a firm issues debt are different from those that determine how much debt it issues. Using a binary choice model to explain the probability of a firm raising debt and a fractional regression model to explain the relative amount of debt issued, we find strong support for both hypotheses. Confirming recent empirical evidence, we find also that, although larger firms are more likely to use debt, conditional on their having some debt, firm size is negatively related to the proportion of debt used by firms.     

Disability insurance and optimal income taxation

This paper studies the design of disability insurance scheme when agents differ in their privately known productivity. We extend the Diamond and Mirrlees (1978) two period model to allow for agents differing ex-ante in their productivity and characterize the optimal nonlinear tax transfer that maximizes a utilitarian welfare function when per-period earnings and age are observable while individuals’ productivity and health status are not observable. We show that the induced tax/benefit scheme should exhibit a marginal income tax that decreases with age for some agents. A marginal subsidy on the young high productive income may be desirable. While the disability scheme always involves the old low productive agents to be indifferent between working and claiming disability benefits, this result is not always true for the old high productive agents.

Internal capital markets and the partial adjustment of leverage

Prior literature provides support both for the existence of target capital structures and internal capital markets (ICM). The issue of whether firms use internal capital markets to reduce deviations from target capital structures, however, has yet to be examined. We provide the first empirical evidence of a link between deviations from target leverage and ICM activity. Based on data that allow us to trace intra-group capital market transactions for property–casualty insurers, our findings provide the first joint evidence that affiliated insurance companies have target leverage ratios and that ICM activity is used to manage deviations from target leverage.     

Tax arbitrage restrictions and financial leverage clienteles

This paper argues that while total short sale constraints are often introduced to rule out tax arbitrage, such constraints are both unrealistic and conceptually problematic. Instead, milder constraints are advocated, which prevent tax arbitrage while still allow short positions. It is demonstrated that a model with these constraints employed can support bond pricing as in the Miller equilibrium, although it leads to a richer set of tax clienteles.     

Dividend taxation and the ownership structure of private firms

This paper examines the effect of dividend taxation on the ownership structure of private firms. I exploit a German dividend tax increase that only affects corporate shareholders owning a minority stake. Using data on private German firms and their shareholders, I find that corporate shareholders reduce their minority stakes in firms after the dividend tax reform. This result is in line with the notion that, because minority shareholders do not have sufficient decision-making power to influence the payout policy, they can only react to a dividend tax increase by selling their shares. This effect is larger when the affected minority shareholders face high dividend tax costs. However, I find a smaller effect when the benefits of the minority stakes are highly relevant for the firm and the affected shareholders, suggesting that non-tax factors mute the response to dividend taxes. In addition, I find that the largest shareholder of the firm buys the minority stake, resulting in greater ownership concentration. These findings extend the prior literature that finds no effect of dividend taxes on the ownership structure of private firms.
