The Hicksian trade cycle with floor and ceiling dependent on capital stock

This article reconsiders the Hicksian multiplier – accelerator model with ‘floor’ and ‘ceiling’. The new thrust is that these constraints are tied to the actual stock of capital, the floor to the depreciation on this stock, the ceiling to capital as a limiting production factor according to the fixed proportions technology that also underlies the principle of acceleration. For capital formation just the Hicksian investment theory is used. The result is one unified model creating economic growth and growth rate cycles.     

Capital utilization and capital accumulation: Theory and evidence

A firm may acquire additional capital input by purchasing new capital or by increasing the utilization of its current capital. The margin between capital accumulation and capital utilization is studied in a model of dynamic factor demand where the firm chooses capital, labour and their rates of utilization. A direct measure of capital utilization-the work week of capital-is incorporated into the theory and estimates. The estimates imply that capital stock is costly to adjust while the work week of capital is essentially costless to adjust. The estimated response of the capital stock to changes in its price and in the required rate of return is more rapid than found in other estimates.     

Building the Knowledge Stock: Lags,Depreciation, and Uncertainty in R&D Investment and Link with Productivity Growth

The search for an appropriate methodology to investigate the relation between R&D investment, knowledge stock and productivity growth is the main purpose of the paper. In analogy with physical assets, we present a model of knowledge capital formation which allows the calculation of the relevant user cost, as well. The proposed model accumulates R&D investment based on a stochastic gestation lag and a geometric depreciation of the stock. The basic parameters underlying the lag structure differ according to the types of research expenditure. The approach is applied to public R&D investment in Italian agriculture; the results provide interesting information about the economic structure of public research effort in Italian agriculture and plausible estimates of its internal rate of return.     

Capital maintenance and depreciation over the business cycle

This paper develops and estimates a stochastic general equilibrium model with capital maintenance, which affects endogenously the depreciation rate of capital. The estimate of maintenance series is found to track survey-based measures for Canada quite closely and to generate the procyclical pattern of maintenance observed in the data. We use our model estimates to infer the time profile of equipment capital depreciation in Canadian and US manufacturing. The depreciation rate is estimated to be volatile and highly procyclical in both countries.     

中国的资本存量与投资效率

本文通过吸收资本存量（K）研究的已有成果,改进了K估算中经济折旧率为常数的假定,采用时变经济折旧率重新估算了1952～2010 年全国的资本存量。我们发现,以本文测算的时变经济折旧代替以往常用的固定折旧率,同时采用永续盘存法的原始公式代替常用的简化公式,有助于提高K估值的准确性。在此基础上,本文估算了宏观资本回报率,与多数文献所认为的宏观资本回报率具有长期下降趋势不同,我们发现1978~2007年中国宏观资本回报率呈长期上升趋势。     

中国分行业资本存量估算：1990~2014年

通过借鉴中国资本存量已有研究文献的成果,以细分行业差别化的折旧率估算为基础,通过分析投资结构和折旧率的关系,估算出第二、第三产业和总量的时变折旧率,系统地估算出1990~2014年总量、三次产业和细分行业的资本存量。估算结果及分析表明:由于投资结构的变化,总量、第三产业折旧率呈下降趋势,第二产业折旧率呈先上升再下降趋势;目前在我国,“过度投资”和“投资不足”并存,且“过度投资”的是资本效率比较低的行业,“投资不足”的是资本效率比较高的行业。解决“投资不足”问题的关键是打破行业垄断,尤其是行政垄断,引入市场竞争机制。     

Capital utilization, economic growth and convergence

Optimal decisions by economic agents regarding the utilization of capital lead to empirically plausible speeds of convergence in one-sector models of economic growth. The relationship between depreciation and capital utilization plays a crucial role in slowing down convergence to the steady state. Cross-country differences in the extent to which the capital utilization decision is internalized along the transition path may lead to differences in convergence rates, even for countries with similar initial and terminal conditions. Finally, by assuming a constant depreciation rate and full capital utilization, standard growth models may be overstating the magnitude of the steady-state equilibrium.     

Investment and employment in manufacturing in U.S. metropolitan areas 1960–1976

This paper develops a simple vintage model of the relation between investment and employment in manufacturing. Parameters of the model are estimated using time series data for the US taken from the Surveys and Censuses of Manufactures conducted from 1954–1976. The results indicate that the age of the manufacturing capital stock was increasing in most major metropolitan areas during this period. Due to capital aging, the nature of technological change, and the pattern of depreciation, the amount of annual investment per worker required to sustain employment in manufacturing rose substantially. The dispersion of growth rates across areas also increased.     

Brand Capital and Entry Order

This paper develops the hypothesis that firms possess a stock of well-established brands, a stock termed brand capital. The firm with the greatest capital is able to introduce new products in response to new information about consumer tastes before rivals. The results using data from the ready-to-eat cereal industry not only support this hypothesis, but also distinguish brand capital from other sources of firm heterogeneity.     

The specification and estimation of interrelated factor demands under uncertainty

This paper studies a model of the firm's interrelated demands for the factors of production incorporating exogenous variables with uncertain future values, multiple quasi-fixed factors, depreciation in use, and non-symmetric internal costs of adjustment. The inputs considered are production labor, non-production workers, capital, inventories of non-finished goods, and capacity and non-production worker utilization rates. A simultaneous system of factor demand equations with constraints is estimated and using U.S. manufacturing data. The model is shown to be tractable under certain assumptions. The results are encouraging given the complexity and the nature of the model.     

The Economic Incentives and Consequences of Land Write-Ups

Firms in Taiwan are allowed to write up their assets when certain conditions are met. Tax benefits from higher depreciation expenses are granted to encourage corporate investment and capital maintenance. Land write-ups, unlike write-ups of depreciable assets, do not generate tax benefits. This paper investigates the economic incentives for firms in Taiwan to write up their land, and the security price reactions to land write-ups.
An analysis of annual financial data for the manufacturing firms listed in the Taiwan Exchange between 1982 and 1992 shows that firms write up their land by a larger amount when raising capital. Firms with relatively higher debt-asset ratios write up their land by a larger amount. Furthermore, the capital raised was invested in working capital or operational assets, but not in securities of other firms. The results suggest that land write-ups may reduce firms' difficulties in raising external capital, and may enhance corporate investments. The result from capital market analysis offers weak evidence that land write-ups are positively correlated with the market adjusted rate of returns of a firm's stock.     

UNEMPLOYMENT,HUMAN CAPITAL DEPRECIATION,AND UNEMPLOYMENT INSURANCE POLICY

This paper presents a structural estimation of a life cycle model with unemployment risk. The model allows for human capital depreciation during unemployment. It is estimated using German and US household‐level data. The data suggest that the adverse impact of unemployment on individual productivity is important in both countries, but quantitatively more relevant in Germany. Moreover, simulations show that the combination of skill depreciation with the generous unemployment insurance system that was in place in Germany until recently is a key factor in explaining the differences in labour market performance between these countries.

新审计报告与资本市场的信息反应——来自股价同步性和股价预测能力双维度的经验证据

新审计报告准则的施行旨在增加审计报告的信息含量及其决策相关性。以2015—2018年沪深非金融上市公司为样本,研究发现新审计报告施行后,上市公司的股价同步性显著下降,公司特质信息含量比例显著上升,股价特质信息效率显著提升,同时新审计报告的施行产生了增量信息。在此基础上,进一步分析新审计报告准则对资本市场特质信息效率的传导机制,发现投资者关注度对新审计报告(关键审计事项的披露数量)影响资本市场特质信息效率的过程中表现出显著的部分中介效应。分样本检验的结果表明,虽然AH股共同上市公司和非AH股共同上市公司之间的结果存在细微差异但整体趋势相似。通过对新审计报告的影响的分析,可以更好地理解该政策对资本市场的影响。     

Determinants of the medium of payment used to acquire privately-held targets

Since private firms have a unique ownership structure, the method of payment decision when acquiring private firms is influenced by a different set of factors than the method of payment decision when acquiring public firms. We find that bidders are more likely to pay for private targets with stock when the capital gain tax rate is relatively high. This relationship is attributed to greater tax benefits to private owners who receive stock in periods when the capital gains tax is high. Bidders are more likely to use stock in takeovers when the targets are high-tech firms, which we attribute to protection against overpayment by using a contingent pricing method. Bidders are more likely to use cash in takeovers since the Sarbanes-Oxley Act, which we attribute to the higher level of due diligence by bidder managers and board members, and therefore a reduced need for contingent pricing methods like stock. Overall, the results suggest the likelihood of using stock to acquire private targets is positively related to the information asymmetry between the parties, while the likelihood of using cash is greater when conditions (such as SOX) reduce the information asymmetry.     

Extending the input–output model with assets

In this paper, the input–output model is extended with assets. It allows us to examine the various assets that are held and used in production. The requirements of assets that must be held by each sector can thus be specified. Extending the input–output model with assets provides a better alternative to the capital stock matrix in the standard Systems of National Accounts. The input–output model is extended by taking the depreciation of fixed assets into full account. This extension allows for the calculation of total holding coefficients that express the amount of assets that are required to be held in each sector in order to satisfy a unit of final demand. In addition, a dynamic version of the extended model is presented. The extended input–output model has been widely applied in China for various purposes.     

资本市场开放对股票定价效率的影响——基于沪港通政策的实证分析

以沪港通政策实施为现实背景，选定2012年11月至2016年11月为研究区间，构造股价信息充分性、股价信息准确性和股价对信息的反应速度三项定价效率核心指标，采用双重差分模型实证检验沪港通政策对我国沪市A股定价效率的影响。研究发现，沪港通政策的推出有助于提高我国沪市A股的股价信息充分性、准确性和股价对信息的反应速度，且对国有企业、高股权制衡度企业、高换手率企业的股票定价效率提高更显著。进一步对比发现,资金双向流动交易机制对沪市A股定价效率的影响具有差异性。因此，应有序扩大沪股通、港股通标的股票范围，不断完善资金双向流动机制，提高股票流动性，加速境内外资本市场接轨。     

Health human capital and economic growth in Sub-Saharan African and OECD countries

This paper investigates the effects of health human capital on the growth rate of per capita income in Sub-Saharan African and OECD countries. Using an expanded Solow growth model, panel data, and a dynamic panel estimator, we find that the growth rate of per capita income is strongly and positively influenced by the stock of, and investment in, health human capital after controlling for other variables. The stock of health human capital affects the growth rate of per capita income in a quadratic way: the growth impact of health human capital decreases at relatively large endowments of health stock. Our estimates suggest that 22% and 30% of the transition growth rate of per capita income in Sub-Saharan African and OECD countries respectively, can be attributed to health. The structure of the relationship between health human capital and the growth rate of income in Sub-Saharan African countries is similar to the structure of the relationship in OECD countries. This implies that increased stocks of health human capital leads to higher steady state income. Our results have interesting policy implications.

Utilization of fixed capital and Soviet industrial growth

Growth rates of output and factor productivity in Soviet industry fluctuate around a long-term downward trend. These fluctuations can be partially explained by fluctuations in the growth of services of capital. The capacity utilization rate is taken as a proxy for the extent of utilization of capital stock. Variations in the capacity utilization rate explain a significant part of the changes in the rate of growth of total factor productivity between 1970–1983. Declines in the capacity utilization rate are caused by errors in the allocation of investment, which create an imbalance of capacities between raw-materials and manufacturing sectors.Useful suggestions by Emil Bej, Robert Cambell, Richard Harmstone, Kenneth Gray, and Josef Brada are grateful acknowledged     

A qualitative dynamical modelling approach to capital accumulation in unregulated fisheries

Capital accumulation has been a major issue in fisheries economics over the last two decades, whereby the interaction of the fish and capital stocks were of particular interest. Because bio-economic systems are intrinsically complex, previous efforts in this field have relied on a variety of simplifying assumptions. The model presented here relaxes some of these simplifications. Problems of tractability are surmounted by using the methodology of qualitative differential equations (QDE). The theory of QDEs takes into account that scientific knowledge about particular fisheries is usually limited, and facilitates an analysis of the global dynamics of systems with more than two ordinary differential equations. The model is able to trace the evolution of capital and fish stock in good agreement with observed patterns, and shows that over-capitalization is unavoidable in unregulated fisheries.
