Lumpy Investment,Lumpy Inventories

The link between the microenvironment (frictions and heterogeneity) and the macroeconomic dynamics of general equilibrium macromodels is influenced by exactly how general equilibrium closes the model. We make this observation concrete using the recent literature on how nonconvex capital adjustment costs influence aggregate investment dynamics. We introduce inventories into a two‐sector lumpy investment model and find that nonconvex capital adjustment costs dampen and propagate investment impulse responses, more so than without inventories. With two means of transferring consumption into the future, fixed capital and inventories, the tight link between aggregate saving and fixed capital investment is broken.     

Financing constraints, irreversibility, and investment dynamics

We develop a model of an industry with many heterogeneous firms that face both financing constraints and irreversibility constraints. We use this model to examine the cyclical behavior of aggregate fixed investment, variable capital investment, and output in the presence of persistent idiosyncratic and aggregate shocks. Our model yields three main results. First, the effect of the irreversibility constraint on fixed capital investment is reinforced by the financing constraint. Second, the effect of the financing constraint on variable capital investment is reinforced by the irreversibility constraint. Finally, the interaction between the two constraints is key for explaining why input inventories and material deliveries of US manufacturing firms are so volatile and procyclical, and also why they are highly asymmetrical over the business cycle.     

Asymmetric capital structure adjustments: New evidence from dynamic panel threshold models

We develop a dynamic panel threshold model of capital structure to test the dynamic trade-off theory, allowing for asymmetries in firms' adjustments toward target leverage. Our novel estimation approach is able to consistently estimate heterogeneous speeds of adjustment in different regimes as well as to properly test for the threshold effect. We consider several proxies for adjustment costs that affect the asymmetries in capital structure adjustments and find evidence that firms with large financing imbalance (or a deficit), large investment or low earnings volatility adjust faster than those with the opposite characteristics. Firms not only adjust at different rates but also seem to adjust toward heterogeneous leverage targets. Moreover, we document a consistent pattern that firms undertaking quick adjustment are over-levered with a financing deficit and rely heavily on equity issues to make such adjustment.     

Productivity and liquidity management under costly financing

We explore theoretically and empirically the relationship between firm productivity and liquidity management in the presence of financial frictions. We build a dynamic investment model and show that, counter to basic economic intuition, more productive firms could demand less capital assets and hold more liquid assets compared to less productive firms when financing costs are sufficiently high. We empirically test this prediction using a comprehensive dataset of Chinese manufacturers and find that more productive firms indeed hold less capital and more cash. We do not, however, observe this for US manufacturers. Our study suggests a larger capital misallocation problem in markets with significant financing frictions than previously documented.     

Investment and financing constraints in China: Does working capital management make a difference?

We use a panel of over 116,000 Chinese firms of different ownership types over the period 2000–2007 to analyze the linkages between investment in fixed and working capital and financing constraints. We find that those firms characterized by high working capital display high sensitivities of investment in working capital to cash flow (WKS) and low sensitivities of investment in fixed capital to cash flow (FKS). We then construct and analyze firm-level FKS and WKS measures and find that, despite severe external financing constraints, those firms with low FKS and high WKS exhibit the highest fixed investment rates. This suggests that an active management of working capital may help firms to alleviate the effects of financing constraints on fixed investment.     

‘Wait-and-See’ business cycles?

Are shocks to firms' profitability risk, propagated by physical capital adjustment costs, a major source of business cycle fluctuations? This paper studies this question using a heterogeneous-firm dynamic stochastic general equilibrium model, where firms face fixed capital adjustment costs. Surprise increases in idiosyncratic risk lead firms to adopt a ‘wait-and-see’ policy for investment. The model is calibrated using a German firm-level data set with broader coverage than comparable U.S. data sets. The main result is that time-varying firm-level risk through ‘wait-and-see’ dynamics is unlikely a major source of business cycle fluctuations.     

Interactions of Corporate Financing and Investment Decisions: A Dynamic Framework

This article analyzes the interaction between a firm's dynamic investment, operating, and financing decisions in a model with operating adjustment and recapitalization costs. Using numerical analysis, we solve the model for cases that highlight interaction effects. We find that higher production flexibility (due to lower costs of shutting down and reopening a production facility) enhances the firm's debt capacity, thereby increasing the net tax shield value of debt financing. While higher financial flexibility (resulting from lower recapitalization costs) has a similar effect, production flexibility and financial flexibility are, to some extent, substitutes. We find that the impact of debt financing on the firm's investment and operating decisions is economically insignificant.     

Debt and managerial rents in a real-options model of the firm

We present a theory of capital investment and debt and equity financing in a real-options model of a public corporation. The theory assumes that managers maximize the present value of their future compensation (managerial rents), subject to constraints imposed by outside shareholders’ property rights to the firm's assets. Absent bankruptcy costs, managers follow an optimal debt policy that generates efficient investment and disinvestment. We show how bankruptcy costs can distort both investment and disinvestment. We also show how managers’ personal wealth constraints can lead to delayed investment and increased reliance on debt financing. Changes in cash flow can cause changes in investment by tightening or loosening the wealth constraints. Firms with weaker investor protection adopt higher debt levels.     

The Real and Financial Implications of Corporate Hedging

We study the implications of hedging for corporate financing and investment. We do so using an extensive, hand‐collected data set on corporate hedging activities. Hedging can lower the odds of negative realizations, thereby reducing the expected costs of financial distress. In theory, this should ease a firm's access to credit. Using a tax‐based instrumental variable approach, we show that hedgers pay lower interest spreads and are less likely to have capital expenditure restrictions in their loan agreements. These favorable financing terms, in turn, allow hedgers to invest more. Our tests characterize two exact channels—cost of borrowing and investment restrictions—through which hedging affects corporate outcomes. The analysis shows that hedging has a first‐order effect on firm financing and investment, and provides new insights into how hedging affects corporate value. More broadly, our study contributes novel evidence on the real consequences of financial contracting.     

Tax planning, regulatory capital planning, and financial reporting strategy for commercial banks

We test whether banks' investment and financing policies canbe explained by tax status. We document changes in bank holdingsof municipal bonds in response to changes in tax rules relatingto deductibility of interest expense. We also document an associationbetween banks' marginal tax rates and their investment and financingdecisions, which is consistent with the existence of tax clienteles.However, banks do not sort themselves perfectly into investmentand financing clienteles because of adjustment costs. We positspecific types of transaction-cost impediments to tax planning,and document that banks apparently trade off these costs againsttax-planning benefits.     

Investment Adjustment Costs: An Empirical Assessment

We evaluate the empirical evidence for costs that penalize changes in investment using U.S. industry data. In aggregate models, such investment adjustment costs have been introduced to help account for a variety of business cycle and asset market phenomena. So far no attempt has been made to estimate these costs directly at a disaggregated level. We consider an industry model with investment adjustment costs and estimate its parameters using generalized methods of moments. The findings indicate small costs associated with changing the flow of investment at the industry level. The weighted average of the industry elasticities with respect to the shadow price of capital, which depends inversely on the adjustment cost parameter, is eight times larger than the largest estimate reported in Levin et al. (2006) . We examine a variety of factors that may account for this discrepancy, but a substantial part of it remains unexplained. Our results therefore suggest that more caution is needed when giving policy advice that hinges on a structural interpretation of large investment adjustment costs.     

Asymmetric adjustment toward optimal capital structure: Evidence from a crisis

We employ dynamic threshold partial adjustment models to study the asymmetries in firms' adjustments toward their target leverage. Using a sample of US firms over the period 2002–2012, we document a negative impact of the Global Financial Crisis on the speed of leverage adjustment. In our subperiod analysis, we find moderate evidence of cross-sectional heterogeneity in this speed, which seems more pronounced pre-crisis and provides little support for the financial constraint view. Over the pre-crisis period, more constrained firms, such as those with high growth, with large investment, of small size, and with volatile earnings, adjust their capital structures more quickly than their less constrained counterparts. These firms rely heavily on external funds to offset large financing deficits, suggesting that their higher adjustment speeds may be driven by lower adjustment costs that are shared with the transaction costs of accessing external capital markets. During the crisis, the speed of adjustment varies with the deviation from target leverage: only firms with sufficiently large deviations attempt to revert to the target, albeit slowly. Overall, our results provide new evidence of both cross-sectional and time-varying asymmetries in capital structure adjustments, which is consistent with the trade-off theory.     

国企“混改”与企业金融资产配置

本文利用2010～2017年中国沪深A股非金融类上市公司面板数据,考察了国企“混改”对企业金融资产配置的影响,并重点分析了国企“混改”过程中企业金融资产配置的动机。结果显示,非国有股东参股促进了国有企业的金融资产投资。机制检验发现,非国有股东参股通过治理效应路径和融资约束路径共同影响了国有企业的金融资产配置行为,具体表现为非国有股东参股带来的监督治理效应和融资约束强化效应均增强了国有企业配置金融资产的预防性储蓄动机,进而促使国有企业增加金融资产投资。上述研究结果表明,非国有股东参股推动的国有企业金融资产投资并非出于短期利益追逐,而是为了平滑企业投资进行的预防性储蓄。本文研究对于如何通过深化混合所有制改革引导企业“脱虚向实”有一定的借鉴意义。     

Testing Q theory with financing frictions

We develop a Q theory of investment under financing constraints. The firm invests and saves optimally facing convex costs of external equity, overhang from outstanding debt, and collateral constraints on new borrowing. Overhang and costs of external equity discourage investment. Conversely, firms anticipating collateral constraints experience a side benefit from investing as installed capital relaxes future constraints. Empirical tests support the model. Conditional on average Q, investment is lower for equity issuers and for firms with large debt overhang. The Kaplan and Zingales and the Whited and Wu indices are used as proxies for future collateral constraints. Consistent with the model, both indices enter investment regressions positively.     

Do Firms Rebalance Their Capital Structures?

We empirically examine whether firms engage in a dynamic rebalancing of their capital structures while allowing for costly adjustment. We begin by showing that the presence of adjustment costs has significant implications for corporate financial policy and the interpretation of previous empirical results. After confirming that financing behavior is consistent with the presence of adjustment costs, we find that firms actively rebalance their leverage to stay within an optimal range. Our evidence suggests that the persistent effect of shocks on leverage observed in previous studies is more likely due to adjustment costs than indifference toward capital structure.     

How Costly Is External Financing? Evidence from a Structural Estimation

We apply simulated method of moments to a dynamic model to infer the magnitude of financing costs. The model features endogenous investment, distributions, leverage, and default. The corporation faces taxation, costly bankruptcy, and linear‐quadratic equity flotation costs. For large (small) firms, estimated marginal equity flotation costs start at 5.0% (10.7%) and bankruptcy costs equal to 8.4% (15.1%) of capital. Estimated financing frictions are higher for low‐dividend firms and those identified as constrained by the Cleary and Whited‐Wu indexes. In simulated data, many common proxies for financing constraints actually decrease when we increase financing cost parameters.     

Investment Dynamics with Information Costs

Investment in physical capital at the microlevel is infrequent and large, or lumpy. The most common explanation for this is that firms face nonconvex physical adjustment costs. The model developed in this paper shows that information costs make investment lumpy at the microlevel, even in the absence of nonconvex adjustment costs. When collecting and processing information are costly, the firm optimally chooses to do it sporadically and to be inactive most of the time. This behavior results in infrequent and possibly large capital adjustments. The model fits plant‐level investment rate moments well, and it also matches some higher order moments of aggregate investment rates.     

The Value of Financial Flexibility

We develop a model that endogenizes dynamic financing, investment, and cash retention/payout policies in order to analyze the effect of financial flexibility on firm value. We show that the value of financing flexibility depends on the costs of external financing, the level of corporate and personal tax rates that determine the effective cost of holding cash, the firm's growth potential and maturity, and the reversibility of capital. Through simulations, we demonstrate that firms facing financing frictions should simultaneously borrow and lend, and we examine the nature of dynamic debt and liquidity policies and the value associated with corporate liquidity.     

Multinationality and capital structure dynamics: A corporate governance explanation

This paper examines the impact of corporate governance on capital structure dynamics. Using ordinary least squares regressions on 17,496 firm-year observations for 2,294 US multinational companies (MNCs) over the period 1990–2018, we find that MNCs with strong corporate governance use more debt than those with weak governance. Furthermore, strong corporate governance is associated with a faster speed of adjustment to capital structure. This relationship is more pronounced for MNCs than domestic companies, particularly for overlevered firms. We also use the two-part zero-inflated fractional regression model, instrumental variable, and structural equation model estimations to deal with any endogeneity concerns associated with the explanatory variables. Overall, our findings, which withstand a battery of robustness checks, suggest that improvements in corporate governance reduce the costs of monitoring for bondholders, resulting in increased debt financing.     

Nonconvex factor adjustments in equilibrium business cycle models: do nonlinearities matter?

Recent empirical analysis has found nonlinearities to be important in understanding aggregated investment. Using an equilibrium business cycle model, we search for aggregate nonlinearities arising from the introduction of nonconvex capital adjustment costs. We find that, while such costs lead to nontrivial nonlinearities in aggregate investment demand, equilibrium investment is effectively unchanged. Our finding, based on a model in which aggregate fluctuations arise through exogenous changes in total factor productivity, is robust to the introduction of shocks to the relative price of investment goods.
