Asset pricing with heterogeneous preferences,beliefs, and portfolio constraints

Portfolio constraints are widespread and have significant effects on asset prices. This paper studies the effects of constraints in a dynamic economy populated by investors with different risk aversions and beliefs about the rate of economic growth. The paper provides a comparison of various constraints and conditions under which these constraints help match certain empirical facts about asset prices. Under these conditions, borrowing and short-sale constraints decrease stock return volatilities, whereas limited stock market participation constraints amplify them. Moreover, borrowing constraints generate spikes in interest rates and volatilities and have stronger effects on asset prices than short-sale constraints.     

How do firms react to the prohibition of long-lived asset impairment reversals? Evidence from China

New Chinese Accounting Standards (CAS) released on February 15, 2006, prohibit the reversal of long-lived asset impairments, effective for reporting periods beginning January 1, 2007 and later. This development in the Chinese market provides a unique experimental setting to directly investigate how firms react to the ban on previously-allowed long-lived asset impairment reversals, especially firms that use impairment charges as “cookie jar reserves.” By contrasting write-off recognition and reversal across the pre- and post- new CAS announcement regimes, we show that firms listed on Chinese stock exchanges recognized less impairment charges during the “transition” period—after announcement of the new standard and before the effective date—than in pre-announcement periods. Meanwhile, firms with substantial previous write-downs reversed more impairment charges to achieve their earnings targets in the transition period. The new CAS also constraints “big bath” reporting by loss firms. As US GAAP prohibits these reversals and IFRS allows them, our empirical evidence depicts firms’ possible reactions in other regimes contemplating doing away with such reversals.     

Determinants of the Method of Payment in Asset Sell‐Off Transactions

Using a sample of asset sell‐off transactions from January 1990 to April 2010, we find that the method of payment used in asset sell‐off transactions is associated with several characteristics cited in the acquisitions research that reflect cash constraints of the bidder. Specifically, bidders facing more stringent cash constraints are more likely to use equity when purchasing assets, while sellers subjected to cash constraints prefer cash when selling assets. Second, we find that the variation in method of payment among asset sell‐off transactions also is partially explained by variables representing asymmetric information. Third, we apply our model to an expanded sample that includes non‐U.S. sellers of assets and find that an equity payment is more likely when sellers are based in countries that have relatively high country risk (more government restrictions), weak shareholder rights, and a weak legal system. Thus, it appears that bidders prefer that sellers share in the risk of the transaction under these conditions.

Econometric evaluation of asset pricing models

In this article we provide econometric tools for the evaluationof intertemporal asset pricing models using specification-errorand volatility bounds. We formulate analog estimators of thesebounds, give conditions for consistency, and derive the limitingdistribution of these estimators. The analysis incorporatesmarket frictions such as short-sale constraints and proportionaltransactions costs. Among several applications we show how touse the methods to assess specific asset pricing models andto provide non-parametric characterizations of asset pricinganomalies.     

Asymmetric Price Movements and Borrowing Constraints: A Rational Expectations Equilibrium Model of Crises, Contagion, and Confusion

This study proposes a rational expectations equilibrium model of crises and contagion in an economy with information asymmetry and borrowing constraints. Consistent with empirical observations, the model finds: (1) Crises can be caused by small shocks to fundamentals; (2) market return distributions are asymmetric; and (3) correlations among asset returns tend to increase during crashes. The model also predicts: (1) Crises and contagion are likely to occur after small shocks in the intermediate price region; (2) the skewness of asset price distributions increases with information asymmetry and borrowing constraints; and (3) crises can spread through investor borrowing constraints.     

Accounting Standards and Earnings Management: Evidence from China

This article examines the effect of an asset impairment–related regulatory reform on earnings management in China. Chinese Accounting Standard No. 8 (CAS No. 8), which prohibits the reversal of long‐lived asset impairments, was promulgated to constrain managerial opportunism with respect to previously recognized impairment loss reversal. CAS No. 8 forbids the reversal of long‐lived asset impairment losses only, while allowing the reversal of short‐term asset impairment losses. Based on a sample of China's A‐share listed companies on the Shanghai and Shenzhen Stock Exchange during the period 2001–2008, we reveal that managers use less current asset write‐downs and more reversals in the post–CAS No. 8 period. However, such reporting practices do not appear to be influenced by managerial incentives to avoid reporting losses and/or for “big bath” accounting purposes.     

U.S. inequality: Debt constraints or incomplete asset markets?

To examine the role of debt constraints and incomplete asset markets (lack of insurance markets) in explaining U.S. inequality, we run horse races between competing models. For a widely used model, we decompose inequality into its fundamental driving forces. The underlying source of inequality in all models is uninsurable idiosyncratic risk. Both debt constraints and incomplete asset markets are needed to account for inequality, but asset market incompleteness is the key friction. It better accounts for the concentration and dispersion of wealth, and is the most costly friction in terms of welfare. Tight debt constraints are important for explaining the lower tail of the wealth distribution.     

R&D sensitivity to asset sale proceeds: New evidence on financing constraints and intangible investment

We examine the intersection between corporate divestitures of tangible assets and investment in intangible capital (R&D) to provide new tests for the impact financing constraints have on real activity. A positive R&D sensitivity to asset sale proceeds indicates binding financing constraints since cash inflows from tangible asset sales are negatively correlated with productivity shocks and not otherwise connected to intangible investment via non-financial channels. Using a variety of estimation approaches, we document a strong, positive link between cash inflows from fixed asset sales and corporate R&D investment, but only among firms most likely facing binding financing constraints. These results offer robust evidence that financing frictions impact the increasingly important yet understudied intangible corporate investments that drive innovative activity, and they highlight a previously unexplored but potentially valuable use of proceeds from fixed asset divestitures.     

The Effect of Mandatory IFRS Adoption on Conditional Conservatism in Europe

We study the effect of mandatory adoption of International Financial Reporting Standards (IFRS) in Europe in 2005 on conditional conservatism. We capture conditional conservatism with a modified version of the Khan and Watts measure (C_Score) that also controls for potential shifts in unconditional conservatism and cost of capital. From a sample of 13,711 firm‐year observations drawn from 16 European countries spanning the 2000–2010 period, we document an overall decline in the degree of conditional conservatism after the adoption of IFRS. We show that the decline in conditional conservatism is less pronounced for countries with high quality audit environments and strong enforcement of compliance with accounting standards using the Brown et al. audit and enforcement index. As asset impairment tests are a key mechanism ensuring conditional conservatism in the IFRS framework, we further examine these. We show that firms booking an asset impairment present a smaller decline in the degree of conditional conservatism relative to firms that do not. We also demonstrate that firms that do not book an asset impairment when evidence suggests the probable need to do so experience a more pronounced reduction in conditional conservatism. We argue that IFRS are conceptually conditionally conservative but that inappropriate application of conditional conservatism principles is likely to prevent financial reporting from reaching the level of conservatism targeted by the International Accounting Standards Board (IASB).     

Asset Measurement in Imperfect Credit Markets

How should a firm measure a productive asset used as collateral? To answer this question, we develop a model in which firms borrow funds subject to collateral constraints. We characterize the qualities of optimal asset measurements and analyze their interactions with financing needs, collateral constraints, and interest rates. Because of real effects, complete transparency would reduce contracting efficiency and, hence, the measurement must be suitably adapted to credit conditions. The optimal measurement is asymmetric and reports precise information about high collateral values if credit frictions are low, but the reverse if credit frictions are high. Tighter credit market conditions may lead to more opaque measurements and increased investment, in the form of inefficient continuations.     

Intangible capital,relative asset shortages and bubbles

Purely technological factors can be a fundamental force behind the emergence of asset price bubbles in developed economies. We analyze an economy in which the production technology utilizes both physical and intangible capital, where the latter cannot be used as collateral for borrowing. Technological change, in the form of increased importance of intangible capital in production, sharpens the borrowing constraints of entrepreneurs, leading to a scarcity of high-yield assets relative to low-yield ones. This can create the conditions for asset bubbles. Additionally, due to the financial frictions, standard dynamic efficiency tests are not valid, and bubbles are not Pareto improving.     

A simple asset pricing model with heterogeneous agents,uninsurable labor income and limited stock market participation

In this paper we study a simple two-period asset pricing model to understand the implications of uninsurable labor income risk and/or borrowing constraints, limited stock market participation, heterogeneous labor income volatilities, and heterogeneous preferences. We appraise the performance of each of these in matching moments of asset returns to the data and show that limited stock market participation generates a significantly large equity premium. We also show that the distribution of wealth between stock market participants and non-participants plays an important role in asset pricing, and that the effect of borrowing constraints on asset returns are similar to that of limited participation. Finally, we discuss the practical implications of our investigation, providing an appraisal of ongoing changes in asset returns.     

“Social Security-Adequacy,Equity, and Progressiveness: A Review of Criteria Based on Experience in Canada and the United States,” Robert L. Brown and Jeffrey Ip,January 2000

Abstract

We consider an optimal dynamic control problem for an insurance company with opportunities of proportional reinsurance and investment. The company can purchase proportional reinsurance to reduce its risk level and invest its surplus in a financial market that has a Black-Scholes risky asset and a risk-free asset. When investing in the risk-free asset, three practical borrowing constraints are studied individually: (B1) the borrowing rate is higher than lending (saving) rate, (B2) the dollar amount borrowed is no more than K > 0, and (B3) the proportion of the borrowed amount to the surplus level is no more than k > 0. Under each of the constraints, the objective is to minimize the probability of ruin. Classical stochastic control theory is applied to solve the problem. Specifically, the minimal ruin probability functions are obtained in closed form by solving Hamilton-Jacobi-Bellman (HJB) equations, and their associated optimal reinsurance-investment policies are found by verification techniques.     

The Effect of Reversibility on a Manager's Decision to Record Asset Impairments

Over time, accounting standards have moved toward presenting more items at fair value on the balance sheet. Consistent with this trend, IAS No. 36 permits an impairment loss on a long‐lived asset to be reversed if the economic value of the asset recovers. This article uses empirical data from an experiment conducted with 118 managers to explore the implication of allowing impairment reversals on a manager's decision to record the loss. Results suggest that permitting reversals significantly increases the likelihood that a manager will record the impairment, especially if the manager has a bonus plan. The bonus plan effect is not caused by the manager's intention to smooth income through impairment reversals, but by his disutility from a bonus forgone if the value of the asset recovers but accounting rules prohibit him from reversing the loss.     

Default Risk, Asset Pricing, and Debt Control

The pricing and control of firms’ debt has become a majorissue since Merton’s (1974) seminal article. Yet Mertonas well as other recent theories presume that the asset valueof the firm is independent of the debt of the firm. However,when using debt finance, firms may have to pay a premium foran idiosyncratic default risk and may face debt constraints.We demonstrate that firm-specific debt constraints and endogenousrisk premia, based on collateralized borrowing, affect the assetvalue of the firm and, in turn, the collateral value of thefirm. In order to explore the interdependence of debt financeand asset pricing of firms, we endogenize default premia andborrowing constraints in a production-based asset pricing model.In this context then the dynamic decision problem of maximizingthe present value of the firm faces an additional constraintgiving rise to the debt-dependent firm value. We solve for theasset value of the firm with debt finance by the use of numericaldynamic programming. This allows us to solve the debt controlproblem and to compute sustainable debt as well as the firm’sdebt value.     

Does the Prohibition of Long-lived Asset Impairment Reversals Affect Corporate Innovation? Evidence from a Quasi-experiment in China

China modified the asset impairment standard in 2007, prohibiting long-lived asset impairment reversal, which it had previously allowed. Using this setting as a quasi-experiment, we investigate how the prohibition of long-lived asset impairment reversal affects corporate technological innovation. Our empirical results demonstrate that the prohibition of impairment reversal has negative impacts on corporate innovation outputs. Further analyses reveal that the negative effect of this prohibition on corporate innovation is more prominent in companies with high discretionary accruals, high shareholding ratios for the largest shareholders, and companies in highly competitive markets.     

Inco Ltd.: Market Value, Fair Value, and Management Discretion

We examine management discretion to decide when and how much to write down an asset, in a unique case where a tracking stock provides an observable market value for the asset. We find that, despite market evidence that Inco Ltd.'s financial statements substantially overvalued the Voisey's Bay nickel mine throughout 1997 to 2000, management chose not to write down the mine until 2002. Inco management used an independent fairness opinion to justify its December 2000 redemption of the tracking stock at 25% of its initial value, indicating almost surely that Inco management was aware of the generally accepted accounting principles (GAAP) impairment. This case illustrates that GAAP's reliance on undiscounted cash flows for impairment decisions allows huge unrecorded disparities between book and market value. The management discretion exercised in this case provides a concrete example of the subjectivity inherent in fair valuation.     

Can European electric utilities manage asset impairments arising from net zero carbon targets?

This paper develops a framework to assess the ability of electric utilities to sustain the forced impairment of carbon emitting power plants and applies it to the European market. We present a new method to measure asset impairment, for both the company and the industry, based on a database of power plants. We develop a novel framework to analyse a utility's ability to transition by investing in green technology assets through the impact on its credit rating metrics. Finally, we apply our framework to European utilities under scenarios set out by the European Commission to limit global warming by imposing net zero carbon emissions constraints on companies. We conclude that most European utilities have the financial capacity to meet the requirements of net zero carbon emissions under the scenarios with timely action. However, a delay of as little as five years could cause serious financial problems across the sector.     

土地资产价格波动与经济中的流动性供给——基于以地融资视角的研究

本文通过构建理论模型探讨土地资产价格波动与流动性供给之间的关系。在本文模型中,土地兼具生产资本与抵押资产属性,银行贷款同时受到投资需求、抵押品价值与信贷额度的约束。本文主要结论是:(1)土地资产价格在低于一个由基础货币供给决定的临界值后,能影响企业的抵押品价值并反映投资需求变化,故而与存款货币流动性供给正相关。这也使土地资产价格变化与企业杠杆周期一致且具有“预期自我实现”特征。(2)基础货币供给能够通过影响土地的流动性价值的方式来引导土地资产价格,前提是央行可掌握土地资产价格外生变化的原因。(3)信贷资产证券化会提高存款货币供给与土地价格的关联度,但也会削弱基础货币供给对土地价格的引导能力。本文的研究有助于认识土地资产价格与货币政策效果以及系统性金融风险的关联机制,为房地产调控政策提供启示。
