The link between bank monitoring and corporate dividend policy: The case of dividend omissions

This study investigates whether bank monitoring influences investor response to a borrowing firm's decision to omit its dividend payments. We establish a new link between the theories of banking and dividend policy in an examination of how bank monitoring and firm dividend signals complement one another to resolve information asymmetries. Results indicate that, for small firms, investors interpret the dividend decision as a function of bank monitoring and the dividend signals taken together. Also reported are the results of tests examining the differences between the monitoring effects of banks versus public and private non-bank lenders.     

What factors determine dividend smoothing by US and EU banks?

Using a relatively large sample of European and US banks for the period 1998–2016, we investigate the determinants of bank dividend smoothing based on agency, asymmetric information and risk‐shifting theories. We show that dividend payout ratio smoothing practices were implemented on both continents before and after the crisis of 2007 and were more strongly pronounced for EU banks. Our findings mostly support agency‐based explanations of bank dividend behavior as evidenced by higher payout ratio smoothing for banks with higher (initial) dividend payouts, lower ownership concentration, public banks, and banks with lower growth opportunities and weaker investor protection. Evidence in favor of asymmetric information explanations is stronger for EU countries, where smaller (more opaque) banks appear to smooth more. In both continents, banks that rely more heavily on equity issuances are found to smooth dividend payout ratios more, suggesting that banks aim at improving access to equity markets. We also provide evidence in support of risk‐shifting, as evidenced by the persistence of dividend payout ratio smoothing in the crisis years and higher dividend smoothing for banks under greater regulatory pressure. Additional analysis using a time series partial adjustment model for dividend levels provides evidence supporting the prevalence of dividend smoothing and the suggested theoretical explanations.     

Linking dividends and capital injections – a probabilistic approach

In the context of collective risk theory, we give a sample path identity relating capital injections in the original model and dividend payments in the time-reversed counterpart. We exploit this duality to provide an alternative view on some of the known results on the expected discounted capital injections and dividend payments for risk models driven by spectrally negative Lévy processes. Furthermore, we present a probabilistic analysis and simple resulting expressions for a model with two dividend barriers, which was recently shown by Schmidli to be optimal in various Lévy risk models when maximizing the difference of dividend payments and injections in the presence of tax exemptions.     

How to get banks to take less risk and disclose bad news

There is wide agreement that before the recent financial crisis, financial institutions took excessive risk in their investment strategies. At the same time, regulators complained that banks did not reveal the extent of their difficulties in a timely fashion thus reducing the effectiveness of government intervention to prevent or mitigate the deleterious effects of the financial crisis. The purpose of this paper is to investigate how regulators can best use certain tools at their disposal to motivate banks to take less risk and to provide adverse information to regulators early. We argue that two tools, namely (i) allowing bank payouts to equity holders even when banks report they are in trouble and (ii) constraining banks’ future investment strategy when they are in trouble can achieve both goals. We show that, in some cases, it is optimal to use both of these tools in combination. That is, in such cases it is optimal to allow equity payouts when banks report they are in trouble, even though such payouts increase the incentive for banks to take excessive risk and even though these payments are financed by taxpayers. We also show that the more socially costly is constraining the bank’s portfolio selection or the more complex are the bank’s assets, the more likely it is that allowing larger payouts and fewer constraints is optimal. Finally we discuss how changes in bank capital requirements interact with inducing disclosure and preventing excessive risk taking.

Politics,credit allocation and bank capital requirements

I develop a normative theory of political influence on bank lending and capital structure. Legislators want banks to make politically-favored loans that reduce bank profits but generate social or political benefits. The regulator uses asset-choice regulation and capital requirements to induce the lending desired by legislators. There are four main results. First, if regulators dislike bank fragility, then credit-allocation regulation should be accompanied by higher capital requirements. Second, banks will resist higher capital requirements, which will be lower when banks have more bargaining power. Third, when politics matters more in bank regulation, the banking sector is larger and more competitive, with higher capital requirements. Fourth, the optimal reporting mechanism, in which banks report their privately-known profitability and the regulator endogenously determines capital requirements and stringency of credit-allocation regulation in response, shows that political influence is stronger when banks are more profitable.     

On capital injections and dividends with tax in a diffusion approximation

We consider a diffusion approximation to a risk process with dividends and capital injections. Tax has to be paid on dividends, but capital injections lead to an exemption from tax. That is, tax is only paid for the aggregate excess of dividends over the capital injections. The value of a strategy is the expected value of the discounted dividend payments after tax minus the discounted capital injections. We solve the problem and show that the optimal dividend strategy is a barrier strategy.     

Sequential payments and optimal pricing in payment systems

This paper studies the intraday payment behaviour between heterogeneous banks as well as optimal intraday pricing schemes. The paper shows the social optimality of payment sequencing, which allows a bank to delay payments until the bank receives payments from the counterparty. The payment sequencing allows a bank with high liquidity cost to ‘recycle’ payment inflow from another bank with lower liqudity cost, reducing the aggregate cost of funding of banks to settle all payments. But we also see that the banks have an incentive to delay payments more than the payment sequencing requires. This underscores the importance of social planner’s role reducing settlement delay, while leaving socially efficient payment sequencing. In this context, we compare two different pricing schemes, a standard throughput guideline and a time-varying intraday tariff, to discuss the optimal incentive mechanisms in payment systems for the ‘socially efficient sequential settlement’.

Asymmetric information and the mode of entry in foreign credit markets

In a newly liberalized credit market, foreign banks with cost advantages are likely to be less informed than domestic banks that hold information on credit risks. These relative advantages may generate incentives for a foreign bank to negotiate acquisition of a domestic bank in order to capture information endowments. However, if it is difficult to assess the value of information held by banks, the foreign bank will face important choices about the optimal mode of entry and what acquisition price to pay. These choices have implications for the survival of domestic banks and how capital is allocated after liberalization.     

The Information Value of the Stress Test

We investigate whether the “stress test,” the extraordinary examination of the 19 largest U.S. bank holding companies conducted by federal bank supervisors in 2009, produced useful information for the market. Using standard event study techniques, we find that the market had largely deciphered on its own which banks would have capital gaps before the stress test results were revealed, but that the market was informed by the size of the gap; given our proxy for the expected gap, banks with larger capital gaps experienced more negative abnormal returns. Our findings are consistent with the view that the stress tests produced valuable information about banks.     

The dark side of liquidity creation: Leverage and systemic risk

We consider a model in which the threat of bank liquidations by creditors as well as equity-based compensation incentives both discipline bankers, but with different consequences. Greater use of equity leads to lower ex-ante bank liquidity, whereas greater use of debt leads to a higher probability of inefficient bank liquidation. The bank's privately-optimal capital structure trades off these two costs. With uncertainty about aggregate risk, bank creditors learn from other banks’ liquidation decisions. Such inference can lead to contagious liquidations, some of which are inefficient; this is a negative externality that is ignored in privately-optimal bank capital structures. Thus, under plausible conditions, banks choose excessive leverage relative to the socially optimal level, providing a rationale for bank capital regulation. While a blanket regulatory forbearance policy can eliminate contagion, it also eliminates all market discipline. However, a regulator generating its own information about aggregate risk, rather than relying on market signals, can restore efficiency and market discipline by intervening selectively.     

Liquidity creation,regulatory capital,and bank profitability

We examine the interrelationships among liquidity creation, regulatory capital, and bank profitability of US banks. We find that regulatory capital and liquidity creation affect each other positively after controlling for bank profitability. However, this relationship is largely driven by small banks and primarily during non-crisis periods. It is also sensitive to the level of banks' regulatory capital and how it is measured. Furthermore, we find that banks which create more liquidity and exhibit higher illiquidity risk have lower profitability. Finally, the relationship between regulatory capital and bank performance is not linear and depends on the level of capitalization. Regulatory capital is negatively related to bank profitability for higher capitalized banks but positively related to profitability for lower capitalized banks. Therefore, a change in regulatory capital has differential impacts on bank performance. Our findings have various implications for policymakers and bank regulators.     

Tax reforms and the capital structure of banks

This paper studies the link between corporate income tax (CIT) reforms and domestic banks’ financing decisions. We use a dataset of CIT reforms and estimate the effect of tax rate changes on leverage, dividend policies and earnings management of banks. The results suggest that taxation influences all three variables. Leverage increases with the CIT rate in the first three years after the reform. The reason is that the statutory CIT rate determines the value of the debt tax shield. A higher tax rate increases incentives to use debt finance when interest payments are deductible from the CIT base. The tax effects we find are statistically and economically significant but considerably lower than those found in previous research. Also, dividend pay-outs increase after an increase in CIT rates. This could indicate that banks actively manage their pay-out policies around tax reforms and adjust their capital structure with changes in dividends. Furthermore, banks increase loss loan reserves in anticipation of tax rate cuts since losses become less valuable with lower CIT rates.     

Banks’ intraday liquidity management during operational outages: Theory and evidence from the UK payment system

We investigate how settlement banks in the United Kingdom’s large-value payment system deal with intraday liquidity and operational risk. In particular, we are interested in payments behaviour towards a bank that is, for operational reasons, unable to make but able to receive payments. If other banks did not sufficiently monitor their outgoing payments, these operational shocks could impact the entire payment system because the affected bank could absorb liquidity from the system. Our game-theoretic model predicts that only early in the day, when they are uncertain about the payment instructions they might have to execute, banks stop sending payments to a counterparty which is unable to make payments. Using a non-parametric method, we find that this prediction is supported by the data, implying that banks effectively contain the disruption caused by the operational outage: payment flows between healthy banks remain unaffected.     

Bank capital in the crisis: It's not just how much you have but who provides it

Bank capital is the cornerstone of bank regulation and is considered a key determinant of a bank's ability to withstand economic shocks. In the area of bank capital regulation, the general view is that more bank capital is better, irrespective of who provides it. In this paper, we investigate whether the investment horizon of bank capital providers matters for bank performance during the recent financial crisis. We observe that banks with more short-term investor ownership have worse stock returns during the crisis. Further exploration suggests that this is partially because banks with higher short-term investor ownership took more risk prior to the crisis but mainly because they experienced higher selling pressure during the crisis. Our results confirm the economic benefit of bank capital in helping banks to perform better during crises. However, when we decompose bank capital by the nature of its providers, we show that more capital is associated with worse performance when it is provided by short-term institutional investors.     

Is Government Regulation of Banks Necessary?

Banks have been involved with and regulated by governments for hundreds of years. Following a brief review of this history, I delineate nine reasons that could justify continued regulation, particularly in the United States. These include deposit insurance, preventing banks from obtaining excessive economic power, reducing the cost of individual bank insolvency, avoiding the effects of bank failures on the economy, protecting the payments system, serving the interests of popularly elected officials, enhancing the Federal Reserve's control over the money supply, suppressing competition, and protecting consumers. Analysis of each leads me to conclude that deposit insurance, which allows banks to hold insufficient capital, is the only public-policy-justifiable rationale for regulation. This concern can be managed with capital requirements; otherwise, banks should only be regulated as are other corporations.     

Cash holdings in private firms

Evidence from a wide sample of Italian private firms shows that cash holdings are significantly related with smaller size, higher risk and lower effective tax rates, therefore supporting predictions from the trade-off model. More cash is also held by firms with longer cash conversion cycles and lower financing deficits, as predicted by the financing hierarchy theory. Reported evidence also shows that dividend payments are associated with more cash holdings, and both bank debt and net working capital represent good cash-substitutes. When controlling for macroeconomic and industry factors, some variables lose their significance, but the general findings are confirmed. Finally, cash-rich companies are found to be more profitable, to pay more dividends and to invest more in a medium-term future horizon.     

Dividend payout strategies and bank survival likelihood: A cross-country analysis

In this cross-country study, we examine whether dividend payout decisions affect the survival likelihood of banks. Using unique international banking data from 11 countries from 2010 to 2019, we find that higher levels of cash dividend payouts increase a bank's survival likelihood, as paying dividends lowers agency problems and cost of debt and facilitates greater public monitoring. Our extended analysis shows an inverted U-shaped relation between large dividends and survival likelihood. At higher levels, payout is related to a safer position of banks in terms of default; however, at very high levels of dividends, when the levels of payouts exceed a threshold, such payout lowers the likelihood of survival. We additionally investigate the effect of the bank type to assess whether differential effects could be realised under the constrained dividend model of Islamic banks compared to the conventional banking model. Our results, interestingly, show that the positive effect of dividend payouts on bank survival is more pronounced in conventional than Islamic banks. This finding is explained by the dominant liquidity management challenges pertaining to the Islamic banking business model in which banks retain more cash and pay lower dividends. Our findings offer important insights and policy implications for regulators, bankers and a broad set of stakeholders engaging with both banking sectors.
