On the relations between demand creation and growth in a monopolistic firm

This paper deals with the allocation of resources over time by a monopolistic firm between growth of the productive capacity and growth of the market-demand capacity. As the demand-creation relations follow an S-shaped curve, different phases in the behavior of the growing firm are conceived in which investment cycles occur both in productive and demand-creation activities.The paper analyzes the case of homogeneous resources as well as nonhomogeneous resources. It is shown that in general the phases in the behavior of the growing firm are preserved in both cases. In the homogeneous case, when there are investment activities in both types of capital, it is shown that the firm will allocate its resources between the two activities in such a way that the ratio of the rate of growth of demand price (with respect to demand-creation capital) and the rate of growth of output (with respect to productive capital) will be equal to one plus the reciprocal of the elasticity of demand and will, therefore, be bounded between zero and one.     

Effect of local government expenditure on the ratio of output to capital: Evidence from panel data at China��s provincial level

This paper divides the expenditure of local government into the productive and nonproductive expenditure for revealing the effect of local government’s expenditure on output-capital efficiency through model and empirical analysis. In general, the elasticity of productive expenditure is more than that of nonproductive in a developing country. Therefore, the drawing effect of productive expenditure on economic growth is more than nonproductive one. However, the positive drawing effect of local government’s expenditure on the ratio of output to capital can be displayed only if the expenditure is within a reasonable scale. When the public expenditure has surpassed the limit, there will be a negative influence. Through our empirical analysis on current Chinese economic data, it shows that the positive drawing effect of local government productive expenditure on the ratio of output to capital is remarkable; however, the positive effect of expenditure on economic construction is critically small. In some areas, the government expenditure behavior has indirectly become the economic intervention and it reveals the negative effect and low efficiency in high speed of economic growth. It is imperative for Chinese government to improve the efficiency of economic growth by adjusting the expenditure structure of local government.     

Uncertainty in the public debt market and stochastic long-run growth

In a continuous time model, a representative household has to allocate its investment and consumption in an optimal manner under conditions of uncertainty. In the present study it is hypothesized that there are two types of assets: a risk-free and a risky asset. The risk-free asset is assumed to be the physical capital, while at the same time uncertainty is allowed to result from the exogenous random variations in the public debt market, rendering in this way government bonds to act as the risky asset. In the endogenous growth framework with productive public investment, the expected long-run growth rate, the dynamic path of consumption as well as the optimal allocation of investment between a risky and a riskless asset, are analytically derived. This kind of treatment allows us to create a locus for the long-run growth over the various levels of uncertainty. The outcome of the analysis is that a rise in uncertainty impacts negatively upon the long-run growth rate. In order to empirically assess the relationship between growth and uncertainty, we lay our emphasis on the US economy for the period 1957:1 to 2008:4. Within the framework of a bivariate BEKK–GARCH(1,1)-M model a significant negative relationship between uncertainty and economic growth has been established.     

International investment in a model of stochastic growth and development traps

This paper investigates the effects of financial integration in a stochastic endogenous growth model of two economies in which heterogeneous agents face fixed costs of productive investment. The removal of investment barriers may enable a poor country to escape from a state of low and unstable growth by leading to large capital inflows and by raising the number of agents who invest in productive capital. However, since the two economies are characterized by increasing returns to capital and since financial integration may lower the saving rate, it is also possible that both countries' growth prospects worsen.     

Housing, Land Prices, and Growth

We consider the effects of land for housingon the growth process within an overlapping generations model.Our original interest was to enquire whether the introductionof land into a growth model might account for a ``virtuous'circle in which saving-up for land (or housing) generates growthand higher land prices, generating further increases in saving,and so on. Such an account is sometimes proposed for high savingrates in East Asia, where mortgage markets are limited or absent.Our analysis does not support such a story. The user cost ofland reduces the resources available for consumption of reproduciblegoods, so that the introduction of intrinsically valuable landinto a growth model lowers the equilibrium stock of capital andraises the equilibrium interest rate. On the asset side, thepresence of land causes life-cycle savings to be reallocatedaway from productive capital towards land. The social optimumin such a model is for land to be nationalized and provided atzero rent. Land markets, far from generating saving and growth,are inimical to capital formation.     

Uncertainty and the specificity of human capital

This paper studies the choice between general and specific human capital. A trade-off arises because general human capital, while less productive, can easily be reallocated across firms. Accordingly, the fraction of individuals with specific human capital depends on the amount of uncertainty in the economy. Our model implies that while economies with more specific human capital tend to be more productive, they also tend to be more vulnerable to turbulence. As such, our theory sheds some light on the experience of Japan, where human capital is notoriously specific: while Japan benefited from this predominately specific labor force in tranquil times, this specificity may also have been at the heart of its prolonged stagnation.     

Reexamination of Economic Growth, Tax Policy, and Distributive Politics

The paper examines the relationship between economic growth, tax policy, and distribution of capital and labor ownership in a one‐sector political‐economy model of endogenous growth with productive government spending financed by a proportional tax on capital income. The analysis shows that inequality in wealth and income can be positively or negatively related to the optimal tax rate. In either environment, higher inequality leads to a lower after‐tax return to capital, thereby reducing the economy's growth rate.     

On the interaction between public and private capital in economic growth

This paper introduces two forms of interaction between private and public capital in an endogenous growth model in which productive government expenditure takes the form of a stock-variable and public capital is used in part as an input in the production of final output and in part to increase its own supply. While the first form of interaction involves the stocks of the two capital-goods and takes place within the final output sector through the specification of the aggregate production function (Cobb?CDouglas vs. CES), the second one concerns the rates of investment in the two kinds of capital. The share of productive public expenditure devoted to output production can be either exogenous or endogenous. Our results suggest that when this share is exogenous, along the balanced growth path the optimal growth rate of the economy is a positive function of the degree of complementarity between the two forms of investment. When the share of productive public expenditure devoted to output production is endogenous, the public capital share in GDP becomes, along with the model??s preference parameters, an important determinant of the economy??s long run growth. We also find that the optimal growth rate is an increasing function of the elasticity of substitution between public and private capital inputs in goods production, and is independent of the complementarity/substitutability between the two forms of investment.     

Population ageing,time allocation and human capital: A general equilibrium analysis for Canada

This study explores the long-term impact of population ageing on labour supply and human capital investment in Canada, as well as the induced effects on productive capacity. The analysis is conducted with a dynamic computable overlapping generations model where in the spirit of Becker [Becker, Gary (1965), A theory of the allocation of time, The Economic Journal, Vol. 75, pp. 493–517.] and Heckman [Heckman, James (1976), A life-cycle model of earnings, learning and consumption, The Quarterly Journal of Economics, Vol. 84, pp. 511–544], leisure has a quality-time feature and labour supply and human capital investment decisions are endogenous. The role of human capital in the growth process is based on the framework used by Mankiw et al. [Mankiw, N. Gregory, Romer, David and Weil, David N. (1992), A contribution to the empirics of economic growth, Quarterly Journal of Economics, Vol. 107, no. 2, pp. 407–437]. The paper indicates that population ageing creates more opportunities for young individuals to invest in human capital and supply more skilled labour at middle age. Consequently, the reduction in labour supply of young adults initially lowers productive capacity and exacerbates the economic costs of population ageing. However, current and future middle-age cohorts are more skilled and work more, which eventually raises productive capacity and significantly lowers the cost of population ageing. Finally, these results suggest that the recent increase in the participation rate of older workers might be the beginning of a new trend that will amplify over the next decades.     

Protectionism, Export Requirements, and Joint Ventures

Economic distortions often accompany the attempt by lower-income countries to develop. This paper examines the consequences of two such distortions: an export-share requirement whereby foreign capital producing in a local enclave is allowed to sell only a fraction of its output in the local protected market, and some local capital must be allowed into a joint venture in the enclave, even if it must be paid a higher return there than foreign capital earns in its country of origin. The welfare effect of such measures is investigated as well as the effect on local wages of measures that drive out some foreign investment. Such a loss of foreign capital may serve to raise the wage rate.     

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.     

Taxation, Human Capital Accumulation and Economic Growth

Previous studies have shown that tax rates and the growth rate of output are negatively related under the assumption that government wastes tax revenues. This paper shows that, if tax revenues are used for human capital accumulation, tax rates and the growth rate can be positively related. An increase in the human capital tax rate will increase (decrease) the growth rate when the initial tax rate is small (large). An increase in the physical capital tax rate will increase the growth rate when savings are completely interest-inelastic. The effects of income taxes and lump-sum taxes on growth are also analysed.

Optimal disaster-preventive expenditure in a dynamic and stochastic model

The purpose of this study is to present an analytical framework for publicly optimal disaster-preventive expenditure. We examine the optimal policy combination of tax rate, disaster-preventive expenditure, and productive government expenditure in a neoclassical growth model, in which natural disasters occur stochastically and partially destroy existing capital. Based on this model, we can decompose the welfare effect of raising preventive expenditure into three effects: the damage reduction, crowding out, and precautionary effects. By identifying these marginal benefits and costs, we obtain the policy conditions that maximize household welfare. Furthermore, we show that optimal prevention is increasing in disaster probability, and by using a numerical example, we show that there is an inverse U-shaped relationship between the expected growth rate and disaster probability.     

Redistributive policy,inequality and growth

Does redistribution increase inequality? Is inequality harmful for growth? Both questions have recently been addressed in a number of single-tax models. In this paper, I examine the relationship between policy, growth and inequality when income and inherited wealth can be taxed at different rates. In the model, parents accumulate human capital and a return-bearing, storable good in order to increase the quality of their children. Inequality arises because the learning ability of children is stochastic. Redistributive labor income taxation has a negative impact on short- and long-run growth while taxation of inherited stocks increases growth. Effects of both taxes on income inequality are ambiguous. A switch from income to inheritance taxation may increase average utility of all generations involved. I calculate a structure-induced equilibrium of the political process by means of a stochastic simulation of the model. In the short run initial wealth-inequality can stimulate growth, while initial inequality of the endowment with human capital is harmful for growth.     

Growth Rate and Level Effects,the Stability of the Adjustment of Capacity to Demand and the Sraffian Supermultiplier

Abstract

The paper presents a simple but complete formal version of the Sraffian supermultiplier model in which (i) growth is led by the autonomous components of demand that do not create capacity; (ii) private productive investment is an induced expenditure; and (iii) income distribution is exogenous. We show that the main results of the long-period and fully adjusted versions of the model in terms of growth rate and level effects are quite similar and therefore that such results in no way require the full adjustment of capacity to demand. We then analyze a simple set of sufficient dynamic local stability conditions that allow the long-period positions to gravitate towards the fully adjusted position in which capacity is adjusted to demand and that also provide the upper limit to demand-led growth paths. Finally, we show how some critics of the model have misinterpreted it as being supply-led and how this has led to a further confusion between the analysis of the tendency towards a constant value of the capacity-saving-determined warranted rate of growth and the proper stability analysis of the opposite process of adjusting capacity to demand (which tends to adjust the warranted rate endogenously to the growth rate of autonomous demand).     

Optimal growth and land preservation

A model of optimal economic growth with a constant population subject to a constraint on the availability of land is presented. It takes account of the dual character of land as a production factor and as a consumption good (environmental amenities) by determining the optimal intertemporal allocation of land between productive and recreational uses. An extension of the analysis for the case of a growing population with endogenous growth based on human capital accumulation shows that if the rate of discount is not very low, then there exists a set of balanced growth paths compatible with a constant allocation of land.     

CORPORATE GOVERNANCE AND CAPITAL ACCUMULATION: FIRM-LEVEL EVIDENCE FROM ITALY

This study investigates the impact of investor protection on firm ownership and capital growth in a model where investor protection is allowed to vary between firms. Using panel data for Italy, we construct firm-level variables to capture the degree of investor protection, which is observable to all shareholders. Empirical evidence indicates that the stronger the investor protection the lower the fraction of equity that is owned by insiders. Results show that higher insider equity ownership is linked to larger risk premiums and higher costs of capital. Implications suggest that the magnitude of capital stock distortions is particularly important when shareholder protection is weak and ownership concentration is high.     

政府生产性支出对产出-资本比的影响——基于中国经验的研究

在国际学术界,尽管有许多经济学家在宏观经济模型框架下研究政府支出对经济增长的影响,但是很少有人从理论和实证角度研究政府支出对产出-资本比的影响,而产出-资本比的提高对发展中国家经济增长至关重要。本文利用政府提供公共物品生产函数,分析政府生产性支出的增加对税前和税后产出-资本比的影响,认为存在着一个能使产出-资本比最大化的最优政府生产性支出规模。在此基础上,本文进行的实证研究结果表明:(1)在我国国家财政生产性支出中,财政基本建设支出与产出-资本比弱正相关,而教育支出和科学研究支出与产出-资本比强正相关;(2)在我国地方财政生产性支出中,财政基本建设支出和产出-资本比弱负相关,财政教育支出和产出-资本比强正相关,而财政科学研究支出与税后产出-资本比强负相关。     

A golden rule of public finance or a fixed deficit regime?: Growth and welfare effects of budget rules

In this paper, we compare growth and welfare effects of various budget rules within an endogenous growth model with productive public capital, utility enhancing public consumption and public debt. We find that introducing a fixed deficit regime does not affect the long run growth rate compared to a balanced budget while establishing a golden rule results in higher growth. Simulations of welfare effects indicate that a golden rule leads to highest welfare followed by a balanced budget and a fixed deficit regime. A maximum fraction of deficit financed public investment is derived. Varying the intertemporal elasticity of substitution shows that economies populated by households who have a strong tendency to smooth consumption should adhere to a balanced budget from a welfare point of view.     

Water and Economic Growth

Several hydrological studies forecast a global problem of water scarcity. This raises the question as to whether increasing water scarcity may impose constraints on the growth of countries. The influence of water utilisation on economic growth is depicted through a growth model that includes this congestible nonexcludable good as a productive input for private producers. Growth is negatively affected by the government's appropriation of output to supply water but positively influenced by the contribution of increased water use to capital productivity, leading to an inverted-U relationship between economic growth and the rate of water utilisation. Cross-country estimations confirm this relationship and suggest that for most economies current rates of fresh water utilisation are not yet constraining growth. However, for a handful of countries, moderate or extreme water scarcity may adversely affect economic growth. Nevertheless, even for water-scarce countries, there appears to be little evidence that there are severe diminishing returns to allocating more output to provide water, thus resulting in falling income per capita. These results suggest caution over the claims of some hydrological-based studies of a widespread global 'water crisis'.
