Cash Flow Sensitivity of Investment

Investment cash flow sensitivity is associated with both underinvestment when cash flows are low and overinvestment when cash flows are high. The accessibility of external capital is positively correlated with cash flows, intensifying investment cash flow sensitivity. Managers actively counteract the variations in internal and external liquidity by accumulating working capital when liquidity is high and draining it when liquidity is low. These results imply that cash flow sensitive firms face financial constraints, which are binding in low cash flow years. Traditional indicators of financial constraints, such as size and dividend payout, successfully distinguish firms that may potentially face constraints, but are less successful in distinguishing between periods of tight and relaxed constraints. These periods are much more clearly separated by the KZ index, which, on the other hand, is less successful in identifying firms that are likely to face liquidity constraints.     

Effects of financial constraints on corporate policies in Australia

We jointly study the impact of financial constraints on Australian companies’ investment decisions and demand for liquidity. By examining a large sample of Australian firms over the period 1990–2003, we find that financial constraints not only reduce the sensitivity of investment to the availability of internal funds, but also increase the responsiveness of cash holdings to internally generated cash flows. Further analysis shows that the impact of financial constraints varies across different cash flow states; that is, financial constraints have a small effect on corporate investment and cash policies when cash flows are positive. In contrast, the severity of constraints is high in negative cash flow years in which the cost disadvantage of external finance coincides with deteriorating operating performance.     

Internal versus External Financing: An Optimal Contracting Approach

We study optimal financial contracting for centralized and decentralized firms. Under centralized contracting, headquarters raises funds on behalf of multiple projects. Under decentralized contracting, each project raises funds separately on the external capital market. The benefit of centralization is that headquarters can use excess liquidity from high cash‐flow projects to buy continuation rights for low cash‐flow projects. The cost is that headquarters may pool cash flows from several projects and self‐finance follow‐up investments without having to return to the capital market. Absent any capital market discipline, it is more difficult to force headquarters to make repayments, which tightens financing constraints ex ante. Cross‐sectionally, our model implies that conglomerates should have a lower average productivity than stand‐alone firms.     

Capital Structure as a Strategic Variable: Evidence from Collective Bargaining

I analyze the strategic use of debt financing to improve a firm's bargaining position with an important supplier—organized labor. Because maintaining high levels of corporate liquidity can encourage workers to raise their wage demands, a firm with external finance constraints has an incentive to use the cash flow demands of debt service to improve its bargaining position with workers. Using both firm‐level collective bargaining coverage and state changes in labor laws to identify changes in union bargaining power, I show that strategic incentives from union bargaining appear to have a substantial impact on corporate financing decisions.     

What drives corporate liquidity? An international survey of cash holdings and lines of credit

We survey chief financial officers from 29 countries to examine whether and why firms use lines of credit versus non-operational (excess) cash for their corporate liquidity. We find that these two liquidity sources are employed to hedge against different risks. Non-operational cash guards against future cash flow shocks in bad times, while credit lines give firms the option to exploit future business opportunities available in good times. Lines of credit are the dominant source of liquidity for companies around the world, comprising about 15% of assets, while less than half of the cash held by companies is held for non-operational purposes, comprising about 2% of assets. Across countries, firms make greater use of lines of credit when external credit markets are poorly developed.     

Cash holdings and R&D smoothing

The sharp increase in R&D investment in recent decades has important but unexplored implications for corporate liquidity management. Because R&D has high adjustment costs and is financed with volatile sources, it is very expensive for firms to adjust the flow of R&D in response to transitory finance shocks. The main contribution of this paper is to directly examine whether firms use cash reserves to smooth their R&D expenditures. We estimate dynamic R&D models and find that firms most likely to face financing frictions rely extensively on cash holdings to smooth R&D. In particular, our estimates suggest that young firms used cash holdings to dampen the volatility in R&D by approximately 75% during the 1998–2002 boom and bust in equity issues. Firms less likely to face financing frictions appear to smooth R&D without the use of costly cash holdings. Our findings provide new insights into the value of liquidity and the financing of intangible investment, and suggest that R&D smoothing with cash reserves is now important for understanding cash management for a substantial fraction of publicly traded firms.     

A theory of corporate financial decisions with liquidity and solvency concerns

This paper studies the impact of both liquidity and solvency concerns on corporate finance. I present a tractable model of a firm that optimally chooses capital structure, cash holdings, dividends, and default while facing cash flows with long-term uncertainty and short-term liquidity shocks. The model explains how changes in solvency affect liquidity and also how liquidity concerns affect solvency via capital structure choice. These interactions result in a dynamic cash policy in which cash reserves increase in profitability and are positively correlated with cash flows. The optimal dividend distributions implied by the model are smoothed relative to cash flows. I also find that liquidity concerns lead to a decrease of dispersion of credit spreads.     

Processes and Accuracy of Cash Flow Forecasting: A Case Study of a Multinational Corporation

Despite its pivotal importance in enterprise management, cash flow forecasting gets little attention from academics perhaps because few of them have access to internal processes and data. In this article, however, the authors explain how cash flow forecasting is organized at Bayer, a large multinational company headquartered in Germany, and which factors influence the accuracy of its forecasts. The research focuses on cash flow forecasts based on the direct method, prepared three times a yearat Bayer, involving about 62,000 individual forecasting items each time. These forecasts form the basis of the company's liquidity and financial risk management, in particular, its foreign exchange risk hedging. The authors explain how local managers in Bayer's entities across the world derive the forecasts, i.e., what information they use as input, how they validate it, and how they deal with potential bias caused by managerial incentive systems. They also analyze whether forecasting processes are affected by characteristics such as business area, size, region, or specific local conditions, and ultimately whether forecasting practices and entity characteristics affect forecast accuracy. The findings show that cash flow forecasting procedures vary substantially across Bayer. While the central finance department gives general guidance on the required cash flow forecasting output and provides direction on the input to be used, there are no detailed instructions on how forecasts are to be prepared. Instead, local managers are free to determine their own forecasting practices. They use different forecasting inputs and validate forecasting inputs and output with different intensities, and they also differ in how they treat possible biases in input data. These findings document the limits of standardization and central control in large multinational corporations resulting from local managers’ need for flexibility to cope with the heterogeneity and dynamism of their environments. At the same time, however, local differentiation increases complexity and may increase errors. Quantitative analysis of forecasting errors shows that forecasts of receipts from customers (cash inflows) are more accurate than forecasts of payments to suppliers (cash outflows). Moreover, forecasting practices affect forecast accuracy. Outflow forecasts are more accurate if managers intensively validate forecasting input; inflow forecasts, if they eliminate input biases that may result from internal target setting or from other managerial incentives, and if they carefully validate their forecasting output. The study provides several insights.

Stockpiling cash when it takes time to build: Exploring price differentials in a commodity boom

Some projects take time to build or are slow to yield cash flows. This may impact the dynamics of investment and liquidity management, although few studies test their financial implications. We exploit the peculiar advantages of copper mines as a laboratory to identify cash-flow sensitivities. In this context, investment decisions depend on the expectations of the long run price of the commodity, while the spread between the spot price and this long run expectations shifts current cash-flows. For this study we compiled a sample of copper firms between 2002 and 2012. We do not find significant effects of cash flow on current capital expenditures, but we do observe a systematic cash flow sensitivity of cash holdings, meaning that some of these transitory earnings are retained as liquidity. This cash stockpiling is stronger among financially constrained firms. In a context of time-to-build, our findings support financial theories emphasizing the salience of cash as buffer stock for liquidity in preparation for future investment opportunities.     

Do bank managers signal through cash flow statements?

We empirically examine the cash flow statements for Japanese banks and whether their managers engage in classification shifting to temper concerns about risk exposure. To create a buffer against liquidity shocks, they shift cash flows from investing and/or financing activities to operating activities. We also find robust evidence that classification shifting intensifies in higher risk situations. Although prior research on managerial discretion focuses on earning management, we are the first to show cash flow management to avoid sequential negative changes in operating cash flows. We show that these activities convey valuable information about changes in banks' risk exposure.     

On the determinants of SME capital structure in Central and Eastern Europe: A dynamic panel analysis

The purpose of this paper is to test how firm characteristics affect SMEs’ capital structure using a unique dataset of micro, small, and medium-sized firms (SMEs) in Central and Eastern Europe (CEE). We carry out a panel data analysis of 3175 SMEs from seven CEE countries during the period 2001–2005, modeling the leverage ratio as a function of firm specific characteristics hypothesized by capital structure theory. By using the cash flow as an explanatory variable, we test some of the predictions of the pecking order theory. According to this theory, firms with more available internal funds should use less external funding. We do find strong evidence in favor of the pecking order theory, given that there is a negative and significant correlation between profitability and leverage. When we control for other firm specific characteristics such as future growth opportunities, liquidity, sales growth, size and assets structure, the cash flow is found to be a strong determinant of firm leverage. We also argue that the determinants of firm leverage may be considerably different depending on firms’ size and age. The empirical results show that cash flow coefficient remains negative and statistically significant only for medium-sized firms, thus suggesting that larger firms with sufficient internal funds use less external funding than comparable smaller firms. We obtain similar results when we estimate the model by firm age; older firms demonstrate similar behavior as larger firms.     

A Unified Theory of Tobin's q,Corporate Investment,Financing, and Risk Management

We propose a model of dynamic investment, financing, and risk management for financially constrained firms. The model highlights the central importance of the endogenous marginal value of liquidity (cash and credit line) for corporate decisions. Our three main results are: (1) investment depends on the ratio of marginal q to the marginal value of liquidity, and the relation between investment and marginal q changes with the marginal source of funding; (2) optimal external financing and payout are characterized by an endogenous double‐barrier policy for the firm's cash‐capital ratio; and (3) liquidity management and derivatives hedging are complementary risk management tools.     

Strategic complementarities and money market fund liquidity management

I use a unique institutional feature of money market funds to identify whether funds hold additional liquidity to guard against and prevent potential investor runs. Specifically, some funds are used as a cash management vehicle for related entities, such as other funds in the fund family. These “internal” funds should experience less outflows during market stress, and should thus have less need to hold this additional liquidity. Indeed, these “internal” prime money market funds do hold lower liquidity than other prime funds. This effect is most pronounced at quarter ends, when there is an exogenous reduction in cash demand from non-US bank dealers.     

Liquidity risk and policy options

On the basis of a liquidity management model, liquidity risks, defined as the probability of payment failures in a real-time gross settlement (RTGS) payment system, may either stem from liquidity management inefficiencies or insufficient cash balances. I will show that penalties charged on the amount of payment failures minimise liquidity risks without interfering with the bank’s technology preferences. I will instead show that liquidity requirements, although as effective as penalties to contain the risk of liquidity shortage, may distort the bank’s technology preferences and cannot stem liquidity management inefficiencies. I will also show that liquidity risks within RTGS payment systems are potentially smaller because they depend more on the liquidity management efficiency than on the randomness of cash inflows and outflows.     

A q Theory of Internal Capital Markets

We propose a tractable model of dynamic investment, spinoffs, financing, and risk management for a multidivision firm facing costly external finance. Our analysis formalizes the following insights: (i) Within-firm resource allocation is based not only on divisions' productivity, as in winner-picking models, but also their risk; (ii) firms may voluntarily spin off productive divisions to increase liquidity; (iii) diversification can reduce firm value in low-liquidity states, as it increases the spinoff cost and hampers liquidity management; (iv) corporate socialism makes liquidity less valuable; and (v) division investment is determined by the ratio between marginal $$ and marginal value of cash.     

Cash holding,trade credit and access to short-term bank finance

Since 1988, cash holding of the UK companies has increased from 10.6% to 16.4% of total assets. To explain this increase, we develop a panel vector autoregression and analyse the dynamics between cash holding and its closest substitutes, trade credit and short-term bank finance. Impulse response functions confirm the signalling theory, as trade credit facilitates access to bank finance. Firms experiencing liquidity shocks resort to cash or trade credit but not to bank finance. Cash holding improves access to trade credit. Additional cash and trade credit trigger a slowdown of the cash conversion cycle explained by agency theory. Cash-rich firms have accumulated more cash than predicted because of an unexpected decline in short-term debt, stressing the role of banks in explaining the increase in cash holding.     

The Corporate Propensity to Save

Why do corporations accumulate liquid assets? We show theoretically that intertemporal trade‐offs between interest income taxation and the cost of external finance determine optimal savings. Intriguingly, we find that, controlling for Tobin's q, saving and cash flow are negatively related because firms lower cash reserves to invest after receiving positive cash‐flow shocks, and vice versa. Consistent with theory, we estimate negative propensities to save out of cash flow. We also find that income uncertainty affects saving more than do external finance constraints. Therefore, contrary to previous evidence, saving propensities reflect too many forces to be used to measure external finance constraints.     

Securitization bubbles: Structured finance with disagreement about default risk

An additional reason for the structured finance boom of the 2000s may have been disagreement about default risk of collateral assets. When risk-neutral investors disagree about average default probabilities, structuring collateral cash flow raises prices by concentrating optimists’ demand on risky tranches. With disagreement about default correlation, low-correlation investors believe in diversification and pay high prices for senior tranches they deem riskless. High-correlation investors value junior tranches they expect to pay whenever aggregate conditions are good. Risk aversion and short selling through credit default swaps reduce the prices of both pass-through and structured securitizations but may increase the return to tranching.     

What determines the composition of a firm's cash reserves?

We investigate what determines variation in the composition of the financial assets that constitute corporate cash reserves and how this variation relates to other key liquidity management practices. The degree to which a firm invests its cash reserves in less liquid, longer-maturity financial assets that earn a higher yield is explained by financial constraints, the ability to accurately forecast short-term liquidity needs, and the firm's likelihood of defaulting on its debt. During years when a firm's cash reserves are required to fund increases in investment or operating expenses the firm transfers funds from less liquid to more liquid financial assets. A firm's decisions relating to the composition of its cash reserves interacts with other key liquidity management practices, such as relying on credit lines for liquidity, extending trade credit or using it as a source of financing, and holding large amounts of inventories. Our findings provide insights on an important component of corporate liquidity management decisions.     

Marketable Incentive Contracts and Capital Structure Relevance

This article investigates the claim that debt finance can increase firm value by curtailing managers' access to “free cash flow.” We first show that incentive contracts that tie the managers' pay to stockholder wealth are often a superior solution to the free cash flow problem. We then consider the possibility that the manager can trade on secondary capital markets. Liquid secondary markets are shown to undermine management incentive schemes and, in many cases, to restore the value of debt finance in controlling the free cash flow problem.
