The Corporate Cost of Capital and the Return on Corporate Investment

We estimate the internal rates of return earned by nonfinancial firms on (i) the initial market values of their securities and (ii) the cost of their investments. The return on value is an estimate of the overall corporate cost of capital. The estimate of the real cost of capital for 1950–96 is 5.95 percent. The real return on cost is larger, 7.38 percent, so on average corporate investment seems to be profitable. A by-product of calculating these returns is information about the history of corporate earnings, investment, and financing decisions that is perhaps more interesting than the returns.     

Sensitivity of Systematic Risk Estimates to the Return Measurement Interval Under Serial Correlation

This paper analytically and empirically investigates the sensitivity of the return measurement interval to the market beta estimate and suggests a market beta estimation method incorporating the investment horizon through a vector autoregressive (VAR) model when there is serial correlation in returns. The analytical relation between the beta estimate and the return measurement interval is obtained. Based on the analytical relation, a decision function for the intervalling effect is provided. It is found that the intervalling effect is mostly caused by January returns.     

Biased Beliefs,Asset Prices,and Investment: A Structural Approach

We structurally estimate a model in which agents’ information processing biases can cause predictability in firms’ asset returns and investment inefficiencies. We generalize the neoclassical investment model by allowing for two biases—overconfidence and overextrapolation of trends—that distort agents’ expectations of firm productivity. Our model's predictions closely match empirical data on asset pricing and firm behavior. The estimated bias parameters are well identified and exhibit plausible magnitudes. Alternative models without either bias or with efficient investment fail to match observed return predictability and firm behavior. These results suggest that biases affect firm behavior, which in turn affects return anomalies.     

The Determinants of REIT Institutional Ownership: Tests of the CAPM

This study examines the determinants of institutional investment demand for REIT common stock. We estimate the demand function for financial institutions using the mean return and CAPM risk measures (beta and standard error) for REIT stocks. The objective is to determine whether institutional investment decisions are influenced by CAPM model attributes. In addition, we examine the predicatability of REIT institutional ownership based on the factors in our model. We employ conventional OLS forecasting techniques, as well as two neural network models in order to deal with possible nonlinearities in the relationships.

Primacy in stock market participation: the effect of initial returns on market re-entry decisions

We examine whether initial returns influence investors’ decisions to return to the stock market following withdrawal. Using a survival analysis technique to estimate Finnish retail investors’ likelihood of stock market re-entry reveals that investors who experience lower initial returns are less likely to return, even after controlling for returns in the last month and average monthly returns for the duration of investing. This primacy effect is robust to accounting for endogeneity in investors’ exit decisions, and other behavioural biases such as recency and saliency of investment experience. Individual investors appear to be subject to primacy bias and tend to put a significant weight on initial experiences in re-entry decisions.     

Estimates of economic rates of return for the U.S. pharmaceutical industry, 1976–1987

Estimation procedures are designed to consider features of publicly-available financial accounting information which allegedly compromise its use to estimate economic internal rates of return. These procedures, which focus on cashflows rather than conventional accounting income measures, are used to investigate the relative profitability of the U.S. pharamaceutical industry. Results indicate that pharmceutical returns exceed returns for comparable U.S. industrial firms during the period encompassed by the study. Differences for these comparisons are substantially less than what is implied by an uniformed use of accounting information, however. In particular, differences in implied internal rates of return of 2.1% to 3.8%, whereas differences in accounting rates of return are 4.0% to 5.6%. Results are robust for a wide variety of assumptions about industry growth rates and investment payout profiles, characteristics which potentially cause accounting-based return measures to differ from underlying internal rates of return.     

大股东控制、政府控制层级与公司价值创造

本文着眼于公司价值的边际增量——投资绩效,从相对更短的价值链,研究了大股东控制、政府控制层级在我国上市公司价值创造过程中的作用与效率,以深入探究所有权结构与公司价值关系的迷雾。基于我国上市公司的经验证据发现:不同的所有权结构在公司价值创造中的作用与效率和终极所有权性质密不可分,大股东追求控制权私有收益对市县级政府和非政府所属上市公司的投资收益产生了消极影响。具体而言:市县级政府控制和非政府控制上市公司的投资绩效受到堑壕效应的消极影响,但利益趋同效应仅在非政府控制上市公司中有所显现;股权制衡对市县级政府和非政府控制的上市公司投资绩效有一定的积极作用。     

我国保险资金境外投资风险防范探析

随着保险业发展速度的加快,保险投资资金的不断增多,使保险资金境外投资逐步成为国内保险机构扩展投资领域、提高保险资金投资收益的重要途径。但与境外投资高收益相伴的是不容忽视的高风险,2008年下半年以来,随着美国次级债风波演变为百年难遇的全球性金融危机,国际金融形势风云突变,对外投资形势日趋严峻,我国保险资金对外投资面临着严峻的风险。本文通过对当前我国保险业保险资金境外投资面临的风险分析,采取理论与案例相结合的方式,从保险监管方式、内部风险控制、资产负债匹配、投资比例限制及投资人才储备等方面提出我国保险资金境外投资风险的具体策略和措施。     

Unbiased estimation of expected return using CAPM

Estimation of expected return is required for many financial decisions. For example, an estimate for cost of capital is required for capital budgeting and cost of equity estimates are needed for performance evaluation based on measures such as EVA. Estimates for expected return are often based on the Capital Asset Pricing Model (CAPM), which states that expected excess return (expected return minus the risk-free rate) is equal to the asset's sensitivity to the world market portfolio (β) times the risk premium on the “world market portfolio” (the market risk premium). Since the world market portfolio, by definition, contains all assets in the world, it is not observable. As a result, an estimate for expected return is commonly obtained by taking an estimate for β based on some index (as a proxy for the world market portfolio) and an estimate for the market risk premium based on a potentially different index and multiplying them together. In this paper, it is shown that this results in a biased estimate for expected return. This is undesirable since biased estimates lead to misallocation of funds and biased performance measures. It is also shown in this paper that the straightforward procedure suggested by Fama and MacBeth [J. Financ. Econ. 1 (1974) 43] results in an unbiased estimate for expected return. Further from the analysis done, it follows that, for an unbiased estimate, it does not matter what proxy is used, as long as it is used correctly an unbiased estimate for expected return results.
