Capital Constraints,Asymmetric Information,and Internal Capital Markets in Banking: New Evidence

A growing literature investigates the role of internal capital markets in mitigating financial constraints faced by the subsidiaries of a conglomerate. Most studies have relied on indirect tests based on correlations between the cash flows and the investment of the subsidiaries. In contrast, we avoid the widespread criticisms of such specifications by providing direct tests that focus on the mechanisms through which internal reallocations of funds occur. We find that internal capital markets are used by multibank holding companies to mitigate capital constraints faced by individual bank subsidiaries. In addition, we show that internal capital management within a multibank holding company involves not only the movement of capital to those subsidiaries with a relatively greater need for capital but also the movement of assets (loans) from less well capitalized to better capitalized subsidiaries by means of loan sales and purchases among the subsidiaries. Furthermore, net loan sales are used to allow efficiency‐enhancing specialization among bank subsidiaries, insofar as those subsidiaries with the best loan origination opportunities are able to focus on loan originations even if they do not have sufficient capital to hold the loans. Our evidence is consistent with banks affiliated with holding companies more actively participating in loan sales and purchases because, by using their internal secondary loan market, they are able to avoid the “lemons” problem faced by stand‐alone banks.     

Determinants of the capital adequacy ratio of foreign banks’ subsidiaries: The role of interbank market and regulation

This paper examines the factors influencing the capital adequacy ratio (CAR) of foreign banks. We test whether the CAR of subsidiaries and branches in developed and developing countries depends on the same factors. We use data from 310 subsidiaries and 265 branches to test the impact of the parent banks’ fundamentals on subsidiaries’ and branches’ capital ratios. We also study how the economic condition and regulatory environment in a bank's home country determine foreign banks’ CAR. Our results provide strong evidence that the CAR of subsidiaries and branches operating in developing and developed countries do not depend on the same set of explanatory factors. We also find that the regulatory framework of a parent bank's home country affects the capitalization of its foreign subsidiaries in the host countries. Finally, we show that specific variables of the parent bank have a stronger effect for foreign banks highly related to the interbank market.     

“Analysis of Incremental Returns of Canadian Mutual Funds”, J. F. Carrière; C. F. Hill,April 2001

Abstract

The determination and allocation of economic capital is important for pricing, risk management, and related insurer financial decision making. This paper considers the allocation of economic capital to lines of business in insurance. We show how to derive closed-form results for the complete markets, arbitrage-free allocation of the insurer default option value, or insolvency exchange option, to lines of business for an insurer balance sheet. We assume that individual lines of business and the surplus ratio are joint log-normal although the method we adopt allows other assumptions. The allocation of the default option value is required for fair pricing in the multiline insurer. We discuss and illustrate other methods of capital allocation, including Myers-Read, and give numerical examples for the capital allocation of the default option value based on explicit payoffs by line.     

An Economic Approach to Capital Allocation

This article starts with primitive assumptions on preferences and risk. It then derives prices consistent with a social optimum within an insurance company and the consumer‐level capital allocation implied therein. The allocation “adds up” to the total capital of the firm (a result echoing findings in the congestion pricing literature—where optimal tolls exactly cover the rental cost of the highway). The allocation follows each consumer's share of recoveries in states of insurer default, weighted by the severity of the default in terms of welfare impact. However, the article argues that an economic approach technically restricts only the capital allocated to marginal units of coverage: inframarginal units could in principle receive different allocations.     

Risk and capital transfer in insurance groups

The aim of this paper is to analyze the effect of capital and risk transfer instruments (CRTIs) on a financial group's risk situation. In this respect, we extend previous literature by accounting for the conglomerate discount on firm value, which is a reduction in shareholder value due to diversification within the group. In general, CRTIs between parent and subsidiaries have a substantial effect on the diversification of risks, economic capital requirements, and default risk, which we study in detail for different types of CRTIs, including intra-group retrocession and guarantees. One main finding is that diversification effects within the group are much lower when taking into account conglomerate discount effects. We believe this aspect to be an important issue in the ongoing discussion on group solvency regulation and enterprise risk management.     

人力资本偏向金融部门如何影响实体经济增长？

通过构建一个包含银行和生产性企业的两部门增长模型,本文系统考察人力资本偏向金融部门如何影响实体经济增长,并利用2008年中国经济普查数据、2003-2015年地级市数据及2011-2013年中国工业企业数据开展实证检验。理论分析表明,人力资本在金融部门与实体部门之间的配置结构对实体经济增长存在两种效应,依次为资本“挤入”效应和创新“挤出”效应,进而导致人力资本配置情况与实体经济增长率之间呈现倒“U”形关系。随后,计量结果为上述理论推断提供了系列经验证据,且机制检验证实人力资本配置到金融部门有助于促进信贷规模扩张。特别地,反事实框架的测算结果显示,人力资本有效配置将提升实体经济增长率约0.45%,而且贡献率随经济发展更加凸显。本文结论表明,应理性看待人力资本向金融部门的不断聚集,不以简单线性关系进行判断,要综合权衡资本“挤入”效应和创新“挤出”效应的相对重要性。     

上市公司权益资本成本的测度与评价——基于我国证券市场的经验检验

权益资本成本(CofEC)是公司筹资和投资决策时需要考虑的重要问题。然而,如何测定公司的权益资本成本,目前尚未得出统一的结论。本文在现有研究的基础上,从事后和事前两个角度测度了我国上市公司的权益资本成本,并从经济和统计两个角度对不同的测度进行了评价。研究得出,不同方法得出的权益资本成本测度差异明显,最大差异达到了12.13%,这些差异对我国公司融资顺序(偏好)是否主要基于资本成本考虑的判断会造成重大影响。从经济角度看,事前权益资本成本测度要优于CAPM和Fama-French三因子模型下事后权益资本成本,在事前权益资本成本测度中,国内外文献中普遍运用的GLS模型下的CofEC表现不够理想,而PEG和MPEG模型下的CofEC能更好地捕捉各风险因素的影响,尽管其时间序列计量误差方差相对较大。     

Insider Ownership,Subsidiary Cash Holdings,and Economic Consequences: Evidence from Listed Chinese Companies

ABSTRACT

Using a large sample of listed Chinese companies, we investigate how the equity ownership of business group insiders affects subsidiary cash holdings. We find that ownership by the largest shareholders and senior managers in the listed parent firm is negatively related to its subsidiaries’ cash holdings, whereas there is a positive relationship with minority equity in subsidiaries. We also find that the market places a more significant value discount on listed firms whose cash holdings are more located in the affiliated subsidiaries. Our evidence demonstrates how cash policy inside business groups is influenced by insider ownership, and it reveals to what extent cash allocated in subsidiaries may suffer from losses in efficiency.     

Dividend Barrier Strategies in A Renewal Risk Model with Generalized Erlang Interarrival Times

Abstract

We consider a renewal risk model with generalized Erlang distributed interarrival times. We assume that the phases of the interarrival time can be observed. In order to solve de Finetti's dividend problem, we first consider phasewise barrier strategies and look for the optimal barriers when the initial capital is 0. For exponentially distributed claim sizes, we show that the barrier strategy is optimal among all admissible strategies. For the special case of Erlang(2) interarrival times, we calculate the value function and the optimal barriers.     

商业银行经济资本管理理论和实践探索

经济资本管理基于资本的稀缺性和高成本性,具有效益约束和风险约束的双效应。近年来,银行管理领域发生的最为显著的变化是,其管理重点逐渐过渡到以风险度量和资本优化配置为核心的全面风险管理。经济资本是贯穿风险度量和资本优化配置这一过程的关键概念,不仅可以提高商业银行的资本管理水平,而且通过发挥经济资本在商业银行经营管理中的预算管理、资源配置和绩效考核作用,推动我国商业银行向现代商业银行转变。从长远看,推行经济资本管理将对商业银行和金融监管当局产生重大的深远影响。     

Firm vertical boundaries,internal capital markets,and firm performance

We investigate how vertical relatedness between business segments of firms affects capital allocation within internal capital markets. Using a battery of tests including exogenous import tariff reductions, we show that investments flow toward segments with better investment opportunities in firms with significant vertical relatedness between segments. This benefit of vertical relatedness is more pronounced in economic environments prone to information problems and in imperfectly competitive industries. Firms with significant inter-segment vertical relatedness also exhibit superior productivity and operating profitability. Overall, we show that superior capital allocation is a channel through which vertical integration impacts real outcomes of firms.

Executive compensation and internal capital market efficiency

We document that chief executive officer (CEO) incentive compensation plays an important role in determining internal capital market (ICM) allocation efficiency. Our results suggest that CEO equity-based compensation can be effective in ameliorating inefficiencies in internal capital allocation decisions. We find that while stock grants play an important role in motivating CEOs to make more efficient internal capital allocation decisions, there is surprisingly no discernible influence of stock options. Our analysis supports the view that private benefits derived by managers are increasing in internal capital misallocation. We also document a strong positive link between CEO incentive compensation and excess value of diversified firms suggesting that the diversification discount can be ameliorated with CEO incentive compensation. The study contributes to the ICM literature and the literature on conglomerate diversification discount.     

Optimal capital allocation using RAROC™ and EVA®

Equity capital allocation plays a particularly important role for financial institutions such as banks, who issue equity infrequently but have continuous access to debt capital. In such a context this paper shows that EVA and RAROC based capital budgeting mechanisms have economic foundations. We derive optimal capital allocation under asymmetric information and in the presence of outside managerial opportunities for an institution with a risky and a riskless division. It is shown that the results extend in a consistent manner to the multidivisional case of decentralized investment decisions with a suitable redefinition of economic capital. The decentralization leads to a charge for economic capital based on the division's own realized risk. Outside managerial opportunities increase the usage of capital and lead to overinvestment in risky projects; at the same time more capital is raised but risk limits are binding in more states. An institution with a single risky division should base its hurdle rate for capital allocated on the cost of debt. In contrast, the hurdle rate tends to the cost of equity for a diversified multidivisional firm. The analysis shows that hurdle rates have a common component in contrast to the standard perfect markets result with division-specific hurdle rates.     

Do venture capitalists imitate portfolio size?

Venture capitalists face the challenge of determining how many entrepreneurial ventures they should invest in. Kanniainen and Keuschnigg (J Corp Finance 9:521–534, 2003) develop a theoretical model based on economic factors that shows how a venture capital fund should set its portfolio size in order to achieve optimal returns. Determining the required economic inputs to this model is difficult in practice however, given the informational asymmetries, uncertainties and ambiguities present in the decision-making environment of venture capitalists. Hence, we contend that general partners of venture capital funds also use their prior venture capital fund management experience, which we refer to as social capital, to overcome the difficulties they face in solving the above optimization problem. Our results support our hypotheses that portfolio size is explained by the interplay of economic and social factors.

Optimal Disbursement of a Sunk Resource and Decentralised Cost Allocation

We consider whether the allocation of the sunk cost of a central resource to operating divisions can be consistent with economically optimal resource consumption decisions. When it is recognised that the central resource is scarce, one may, in principle, defend the allocation of sunk cost, if it measures the opportunity cost of usage. However, typically it has been proposed that such allocations are, at best, a proxy for opportunity cost. Applying classical control theory techniques in a wide range of operating environments, we are able to identify cost allocations that exactly equal opportunity cost. Hence, for our model environment, we provide a rationale for sunk cost allocation in terms of guiding optimal decisions, in contrast to the traditional defence in terms of providing a proxy for opportunity cost. We demonstrate clearly how cost allocations are related to opportunity costs, and identify the circumstances under which the allocation of full costs or alternatively a fixed proportion (related to acquisition conditions) of costs, results in the implementation of economically optimal resource consumption decisions.     

Cyclical adjustment of capital requirements: A simple framework

We present a model of an economy with heterogeneous banks that may be funded with uninsured deposits and equity capital. Capital serves to ameliorate a moral hazard problem in the choice of risk. There is a fixed aggregate supply of bank capital, so the cost of capital is endogenous. A regulator sets risk-sensitive capital requirements in order to maximize a social welfare function that incorporates a social cost of bank failure. We consider the effect of a negative shock to the supply of bank capital and show that optimal capital requirements should be lowered. Failure to do so would keep banks safer but produce a large reduction in aggregate investment. The result provides a rationale for the cyclical adjustment of risk-sensitive capital requirements.     

Optimal portfolios when volatility can jump

We consider an asset allocation problem in a continuous-time model with stochastic volatility and jumps in both the asset price and its volatility. First, we derive the optimal portfolio for an investor with constant relative risk aversion. The demand for jump risk includes a hedging component, which is not present in models without volatility jumps. We further show that the introduction of derivative contracts can have substantial economic value. We also analyze the distribution of terminal wealth for an investor who uses the wrong model, either by ignoring volatility jumps or by falsely including such jumps, or who is subject to estimation risk. Whenever a model different from the true one is used, the terminal wealth distribution exhibits fatter tails and (in some cases) significant default risk.
