ACCRUED CAPITAL GAINS, PERSONAL INCOME AND SAVING IN THE UNITED STATES, 1948–1964

Capital gains are an important source of personal income in the United States but they are not included in the national accounts or the official estimate of personal income and saving. Individuals report their realized gains for tax purposes but the economic theorist would include both realized and accrued gains in income. National income theorists continue to debate whether capital gains should be included in income but, because of the many conceptual and statistical problems involved in estimating capital gains, no satisfactory estimates have been developed. Consequently, the debate has stayed mainly at the theoretical level. This paper deals with the methodology of estimating accrued capital gains. A simple analytical model is developed to estimate capital gains from data on market value and net acquisitions of an asset but the model can be adapted to incorporate asset prices directly. It is shown that the methods used for estimating accrued gains in the past are special cases of the model proposed in the paper. The model is then used for estimating gains accruing to individuals in the United States on their holdings of corporate stock, real estate and livestock during 1948–1964.
During this period accrued gains have amounted to roughly five times the realized gains reported for tax purposes; corporate stock and real estate are the most important sources of capital gains and corporate stock accounts for almost two-thirds of all accrued gains. The paper goes on to examine the implications of these estimates for the existing series on personal income and saving in the United States. The inclusion of accrued gains would increase the variance in the official estimates but personal saving is affected more than personal income. The paper concludes with an evaluation of these results and some suggestions for further research.     

中国主要省区物质资本与人力资本利用效率及投资取向

要实现区域的可持续发展,提高资源利用效率是一个根本性的问题。而作为主要生产资源的物质资本与人力资本的利用效率就具有更重要的意义。文章以经济增长理论为依据,利用生产函数分析了中国主要省区物质资本与人力资本对经济增长的贡献率,发现1990年代之后大多数省区的人力资本贡献率已超过了物质资本的贡献率,说明经济增长方式已发生了由外延式向内涵式的很好转变。进一步根据生产者均衡理论,计算了主要省区物质资本与人力资本的利用效率,发现大部分省区的利用效率没有达到最优状态,但1990年代以来利用效率在不断提高。在此基础上,计算了通过提高两项资本利用效率可带来的GDP增长潜力,发现当利用效率达到最高时GDP可增长近24%。由此给出了各省区物质资本与人力资本投资比例的调整方向。     

PRODUCTIVE CAPITAL IN ITALY: A DISAGGREGATED ESTIMATE BY SECTORS OF ORIGIN AND DESTINATION: 1985–88

This study presents a series of matrices of the capital stock disaggregated both by branch of origin and by branch of destination for the years 1985 to 1988 for Italy. The tables, whose dimensions are 23 × 23, were constructed using the perpetual inventory method and are based on disaggregated time series of gross capital formation provided by Istat (Italian Statistical Institute). The tables refer to both gross and net capital (with straight-line depreciation) and have been tested on alternative hypotheses for the average expected service lives of capital goods and their survival functions.     

ALTRUISM,EGOISM, AND THE ROLE OF SOCIAL CAPITAL IN THE PRIVATE PROVISION OF PUBLIC GOODS*

The economic approach to understanding human behavior has encountered serious difficulties when attempting to explain the private provision of public goods, such as voting and charitable contributions to large organizations. To gain insights into these important issues, this study takes an interdisciplinary approach. The individual is modeled formally in terms of dual egoistic/altruistic utilities, and the recursive relation between altruism and the existence and production of social capital is developed. The model is analyzed as a non-cooperative game between the egoistic and altruistic selves. The socialized rational actor that results from the combination of social capital, dual utilities, and non-cooperative behavior resolves a number of public goods paradoxes. Comparative statics and the dynamics of social capital formation are explored.     

CONVERGENCE IN THE UK SERVICE SECTOR: FIRM LEVEL EVIDENCE, 1988–1998

Bernard and Jones (1996) have previously argued that similarity in the technologies used by firms in the service sector helps to explain evidence of absolute convergence at the cross‐country level. This paper searches for convergence at the firm level using data for the UK service sector over the period 1988–1998. Initial mixed support for this view is partly explained by strong business cycle effects in the data. Upon closer examination we find evidence that convergence was more likely in industries that had high levels of technology investment, greater exposure to new technologies and high levels of absorptive capacity.     

MONETARY EXPANSION AND PRODUCTIVE PUBLIC EXPENDITURE IN A CASH‐IN‐ADVANCE ECONOMY*

Using a dynamic optimization model that incorporates a cash‐in‐advance constraint on both consumption and investment and productive public capital financed by a lump‐sum tax and seigniorage, this paper analyses the steady‐state effects of an increase in the inflation rate (the money growth rate) on output, private capital and welfare. The effects are negative at high inflation rates. However, at low inflation rates, the effects depend on the amount of lump‐sum tax revenue collected and therefore are either positive or negative.     

HUMAN CAPITAL INVESTMENT IN HEALTH: A MEASUREMENT FRAMEWORK AND ESTIMATES FOR THE UNITED STATES, 1952–78

Lack of a conceptual basis for measuring human capital investment in health has hampered efforts to expand national accounting systems to include human capital investment. This paper presents a conceptual basis for developing estimates of this health investment, an estimation methodology consistent with the conceptual basis, and preliminary estimates for the United States for 1952-78. While much work remains to be done before comprehensive estimates of investment in health are achieved, it is clear that previous estimates based on answers to the question, “What improves health?” have included some inappropriate expenditures while excluding others that should be included. The conceptual basis presented here leads to a methodology for separating health care costs (not the costs of illness) into maintenance and gross investment. Gross investment can be further separated into net investment and the sum of damages and depreciation but empirical implementation of this step is not attempted here.     

THE SUBSTITUTABILITY OF CAPITAL, LABOR, AND R&D IN US MANUFACTURING

This paper examines the relationship between inputs in industrial production. The inputs studied here are capital, labor, and research and development (R&D). Using translog technology, our cross-industry analysis of six industries reveals that capital and labor are complements in production while R&D and labor are substitutes. However, the relationship between capital and R&D is not so clear cut. It is also found that constant-returns-to-scale hold for only two of the six industries. A test of sensitivity to changes in the R&D depreciation rates suggests that some industries are sensitive to such changes.     

TRENDS IN HOUSEHOLD WEALTH IN THE UNITED STATES, 1962–83 AND 1983–89

Using the 1983 and 1989 Surveys of Consumer Finances, I find evidence of sharply increasing house-hold wealth inequality over this period. Whereas mean wealth increased by 23 percent in real terms, median wealth grew by only 8 percent. The share of the top one-half percentile rose by five percentage points, while the wealth of the bottom two quintiles showed an absolute decline. The Gini coefficient increased from 0.80 to 0.84. Almost all the growth in real wealth accrued to the top 20 percent of wealthholders. In contrast, the degree of wealth inequality was almost identical in 1983 as in 1962, and real wealth growth was more evenly distributed across the wealth distribution. There is also evidence that the sharp increase in wealth inequality from 1983 to 1989 was due to a correspondingly sharp rise in income inequality, the increase of stock prices relative to housing prices, and relatively slow inflation.     

CONSUMPTION (IN)EFFICIENCY AND FINANCIAL ACCOUNT MANAGEMENT

Consumption may be inefficient when a household cannot choose the optimal bundle of goods at a minimum cost. After discussing alternative approaches, this paper proposes the use of money metric indirect utility function motivated by Feenstra and Varian in measuring consumption inefficiency. Then, Bamoul–Tobin transactions demand for money model is extended to show how household ability to manage its income, expenditure and financial accounts may affect consumption inefficiency. Results of the stochastic cost frontier approach, which is employed in estimation and the prediction of the European Union household consumption inefficiency, suggest that household expenditure performance is partly explained by the changes in the consumption efficiency and the efficiency is not independent of financial account management.     

DEPRECIATION, OBSOLESCENCE AND THE ROLE OF CAPITAL IN GROWTH ACCOUNTING

Maurice Scott has argued that the neoclassical production function and growth accounting are fundamentally flawed as tools for understanding the growth process. If the role of capital were correctly evaluated, then (he argues) the famous 'residual' of growth accounting would disappear. Contrary to these claims, this paper seeks to show that growth accounting gives correct answers to interesting questions, even when all technical progress is embodied in new capital goods and even when depreciation is entirely due to obsolescence.
