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.     

Can government's choice of a high inflation policy be rational?

Out of the two inflation tax equilibria—i.e., the two inflation rates which bring the same revenue to the government—the higher one is not infrequently chosen. It is shown that such a choice may not be irrational for a government whose policy includes a financial repression and exchange rate controls and which is trying to maximize public sector expenditures. However, such policy is not sustainable in the long run, whatever its short-term advantages may be. Hence, policy makers should always weight advantages of higher public sector expenditures today against hardships of inevitable stabilization programs in the future.     

The rise of service employment and its impact on aggregate productivity growth

This paper investigates how the employment shift from manufacturing toward service sectors affects the rate of economic growth when services play their role both in intermediate and in final demand. Our model includes as a special case both Baumol’s [Baumol, W.J., 1967. Macroeconomics of unbalanced growth: the anatomy of urban crisis. American Economic Review 57 (3), 415–426] model, in which services are produced only for final consumption, and Oulton’s [Oulton, N., 2001. Must the growth rate decline? Baumol’s unbalanced growth revisited. Oxford Economic Papers 53 (4), 605–627] model, in which services are entirely devoted to intermediate demand. We show that, given that the growth rate of productivity in the service sector is lower than that in the manufacturing sector, both the employment share in manufacturing and the rate of economic growth will decline in the long run irrespective of the size of the elasticity of substitution between labor and service input.     

ICT-specific technological progress in the United Kingdom

This paper analyses the impact of rapid technological change in the information and communications technology (ICT) sector on economic growth in the United Kingdom. We find that technological progress specific to the ICT sector accounts for around 20–30% of long-run labor productivity growth. We demonstrate that a permanent increase in the growth rate of ICT-specific technological progress will increase the investment expenditure share of GDP but lower the aggregate depreciation rate, while an increase in the return to investment in ICT will increase both the expenditure share and the depreciation rate.     

Robust determinants of health care expenditure growth

Our aim is to disclose robust explanatory variables for health care expenditure (HCE) growth by introducing to this field of research a method that is especially well suited for situations of ‘model uncertainty’: the Extreme Bounds Analysis (EBA). We analyse data for 33 OECD countries over the period 1970–2010 and include – as far as it is statistically feasible – all macroeconomic and institutional determinants of HCE growth in the EBA that have been suggested in the literature. Furthermore, we analyse to what extent outliers in the data influence the results. Our results confirm earlier findings that GDP growth and a variable representing Baumol’s ‘cost disease’ theory emerge as robust and statistically significant determinants of HCE growth. Depending on whether or not outliers are excluded, we find up to six additional robust drivers: the growth in expenditure on health administration, the change in the share of inpatient expenditure in total health expenditure, the (lagged) government share in GDP, the change in the insurance coverage ratio, the growth in land traffic fatalities and the growth in the population share undergoing renal dialysis.     

Bacon and eltis on growth,government, and welfare

In a recent book, Robert Bacon and Walter Eltis attribute Britain's relatively slow economic growth since 1961 to rapid expansion of her public sector. The article disputes both their analogy between the public sector and the physiocrats' sterile sector and their contention that wage demands increase because the marginal public expenditure is not worth the taxes it requires. The wage-tax spiral, if of empirical significance, seems likely to proceed whatever the virtues of public expenditure. This is a fault in the industrial relations system and is by no means sufficient reason to judge the public sector overgrown.     

A note on the sustainability of full employment in the presence of budget deficits

In a recent issue of this journal, Tymoigne and Wray, as well as Palley, discussed whether economies can experience stable full-employment equilibria with persistent public budget deficits. This implies continuous growth of a stock-variable: high-powered money and/or government bonds in the hands of the private sector. Their discussion assumed a stationary state. The question is whether such a situation can be regarded as sustainable over time. This paper argues that a satisfactory solution to the problem can be found only by abandoning the hypothesis of stationary state and considering the effects that different compositions of public expenditure have on the rate of growth. To have a stable full-employment equilibrium with budget deficits, the economy must grow. Since the economy is assumed to be in full employment, the growth of aggregate output must be entirely due to the growth of productivity, which can be realized by changing the composition of public spending in favor of productive expenditures.     

A macrotheoretic analysis of inflation,taxes, and the price of equity

This paper examines the effects of higher inflation on asset prices via the impact on effective tax rates. The problem is addressed in a full macroeconomic context where explicit attention is paid to the government budget constraint. The analysis shows that the magnitude of the inflationary impact on asset prices varies significantly according to the nature of the government's fiscal response to changes in tax revenues generated by more inflation; in particular, by whether increased inflation revenues are met by an equal increase in public expenditures or by commensurate reductions in other tax parameters which keep total revenues constant.     

Outsourcing and productivity growth in services

Outsourcing from manufacturing firms has fueled some of the service sector's rapid growth. We model the firm's decision to outsource and show that increases in outsourcing may explain part of the increase in the divergence in productivity growth between manufacturing and services. We also analyze the implications of outsourcing for output and productivity growth of service industries. Our findings indicate that it has reduced service sector productivity in the short run. In contrast to earlier work on services (Baumol, W.J., 1967. American Economic Review 57, 415–426. Baumol, W.J., Blackman, A.B., Wolff, E.N., 1985. American Economic Review 75, 806–817), we project that productivity growth in services is likely to increase, once demand growth from manufacturing due to outsourcing subsides.     

关于公共支出与经济增长的国内外研究综述

公共支出与经济增长的关系一直以来为经济学家们所争论。持公共支出促进经济增长观点认为,政府公共支出在经济增长中发挥着重要作用,因为它为经济发展提供了大量的公共品和其他具有外部效应的公共福利或服务,从而鼓励和便利了私人投资,形成了一个较好的投资环境,促进了经济增长。而持反对意见的认为,公共支出往往是生产率较低的,为融通政府支出而形成的高税收又会对私人部门的消费和投资造成很大的负面影响,因此,必须缩减政府支出,才能保证经济增长。当然也有人持两者根本就没有关系的观点。     

Government size,composition of public spending and economic growth in Brazil

The performance of the fiscal policy is largely affected by the relationship between government size, composition of public spending and economic growth. We use a theoretical framework to find optimal relations among these variables and confront them with a panel data for the Brazilian states. Private capital and government spending are substitute inputs in production as the Brazilian states require provision of public spending to fill gaps in the underdeveloped private sector. Public investment and current government expenditures are combined in fixed ratios in the overall government spending due to strong rigidity of the public budget. The optimal share of public investment is considerably lower than current expenditures, as occurs in developing countries characterized by low economic dynamism. Finally, the average tax burden from the data is below the estimated optimal level, meaning that there is space for increasing tax rate without harming economic growth for some Brazilian states.     

Income taxes, spending composition and long-run growth

The focus of this paper is threefold. First, it reexamines the impact on long-run growth of changes in flat-rate income taxes when a fraction of total government expenditures is used to provide public services that affect the productivity of privately held inputs. Second, for a given tax policy, this paper studies the impact of government expenditure composition on the rate of economic growth. Third, since demographics follow an overlapping generations structure and fiscal policy affects the economy's productivity, the paper features the role of productivity as a means of redistributing income across generations. The economy is analyzed numerically and policy experiments are carried out.     

STRUCTURAL CHANGE IN A SMALL OPEN ECONOMY: AN APPLICATION TO SOUTH KOREA

This paper develops a dynamic general equilibrium model and studies structural change in a small open economy with two tradable sectors, agriculture and manufacturing, and a non‐tradable sector, services. In addition to obtaining results for a falling employment share of agriculture and a rising share of services, we demonstrate analytically the hump‐shaped share of manufacturing by identifying two countervailing effects: the productivity effect and the Balassa–Samuelson effect. The first effect, arising from differential rates of productivity growth among sectors, increases the share of manufacturing; the second effect, together with low rates of substitution between products, enhances the service sector and eventually draws labour from the manufacturing sector. At the aggregate level, however, the economy maintains a constant rate of growth. We calibrate the model with data from South Korea and find that the calibration fits the country's historical path of structural change.     

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.     

产业结构变迁、劳动力市场扭曲 和中国劳动生产率增长放缓*

自2007年以来,中国的劳动生产率呈现出增长放缓的趋势。本文建立了包含劳动力市场扭曲和部门效率差异的三部门一般均衡模型,对劳动生产率增长放缓的原因进行了分析。本文的模型可以较好地拟合劳动力部门间再配置和劳动生产率增长放缓的特征事实。数值模拟结果表明,第三产业劳动生产率低速增长是导致中国总劳动生产率增长放缓的主要原因,而劳动力市场扭曲的减弱和第一产业劳动生产率的加速增长则对总劳动生产率增长放缓起到了遏制作用。这些结果证明,劳动生产率的增长放缓在很大程度上是产业结构变迁带来的。政府可以实施放松服务业进入规制和消除劳动力市场扭曲等政策,提高总劳动生产率的增长率。     

Structural transformation and productivity growth in India during 1960–2010

In this paper, we examine the role of structural change and sectoral productivity growth in explaining the aggregate productivity of India relative to the United Sates during 1960–2010. We set up a simple two sector general equilibrium model and calibrate it to fit the structural transformation of United States. Our calibrated model for India highlights the relative importance of agricultural productivity growth in explaining its slow process of catching up in terms of aggregate productivity. We show that India could have progressed at a much faster rate and closed a substantial part of its aggregate productivity gap if its agricultural sector had grown at a rate at par with the United States. It is India's relative productivity growth in the non-agricultural sector that explains all the recent success in its closing the aggregate productivity gap with the United States. We also found that an elimination of relative distortion in agriculture in India could result into a modest improvement in the aggregate labour productivity.     

Did the rising importance of services decelerate overall productivity improvement of Turkey during 2002–2007?

This paper answers the question of what would have been the growth rate of aggregate productivity in Turkey between 2002 and 2007, had it realized China’s rates of productivity growth in agriculture, industry, and services. It does this in a three-sector general equilibrium model calibrated to the Turkish economy over the 2002–2007 period. The main findings are: (i) Turkey would have had much higher aggregate productivity growth over this period if it had experienced China’s service sector productivity growth; (ii) very low productivity growth rates in finance and in the non-market service sector are the main culprits behind Turkey’s weak service-sector performance.     

Tax-spending policies and economic growth: Theoretical predictions and evidence from the OECD

We present an endogenous growth model to study the growth effects of the composition of government expenditure and the associated tax burden. When we use data from a set of 23 OECD countries during 1970–2000, our econometric results support the predictions of the theory. The share of productive government expenditure is associated with higher growth, and this result is more robust when we use effective average tax rates and statutory tax rates as measures of the tax burden. With respect to the tax burden, different tax rates have different growth effects.     

Sources of Productivity Growth Dynamics: Is Japan Suffering From Baumol's Growth Disease?

This study examines the sources of labor productivity growth dynamics in Japan (1970–2010) and investigates the extent to which Japanese economic performance has been affected by Baumol's growth disease (BGD). We find that BGD silently undermines Japanese economic growth. However, the magnitude is miniscule, and consequently the aggregate labor productivity growth rate has not been decreasing monotonically. We also explore how BGD is arising and why it is small in the Japanese economy. BGD is weak because (1) the positive Baumol growth effect is also working in certain services sectors and (2) BGD is not a durable phenomenon: even if a sector begins to suffer from BGD, it is likely to recover quickly.
