Public and private Investment in Mexico and Chile: An empirical test of the complementarity hypothesis

This paper addresses the important question of whether government investment spending, rather than overall public expenditures, exerts a positive effect on economic growth and productivity. Using time-series data for Chile and Mexico, it estimates a linear growth model that incorporates a number of relevant quantitative and qualitative variables for each country. The empirical results suggest that for both Chile and Mexico, increases in public and private investment spending have a positive and significant effect on the rate of growth in productivity. Moreover, the results for Mexico show that increases in government consumption expenditures have a negative effect on the rate of productivity growth, thus suggesting that the composition of government spending is at least as important as the growth rate of these expenditures in affecting economic growth. From a policy standpoint, these findings call into question the current trend among Latin American countries of indiscriminately reducing public spending because they fall disproportionally on capital expenditures—the type of spending needed to secure the long-term efficiency gains from market-oriented programs.     

The Effect of Public Infrastructure on Cost Structure and Performance of Chinese Provinces*

This paper estimates a translog cost function for 29 Chinese provinces between 1979 and 2018. The results imply that investment in public infrastructure reduces costs in all provinces. Comparing the estimated rate of return to infrastructure with the rate of return to private capital, our results indicate underinvestment for the initial period after the economic reforms; however, after 2010 our results show overinvestment in infrastructure. Infrastructure capital is a substitute input to labor, private capital and intermediate inputs. Finally, public infrastructure growth contributes positively to labor and total factor productivity growth, but the effect is small. The growth of private capital and intermediate inputs are the most important factors that boost the growth of labor productivity.     

Oil revenues for public investment in Africa: targeting urban or rural areas?

This paper investigates the effects of oil-financed public investment on economic growth and poverty reduction using a dynamic multi-sectoral general equilibrium model featuring inter-temporal productivity spillovers. The paper shows that the relationship between resource-rent flows and real exchange rates, output growth, and poverty is less straightforward than simple models of the “resource curse” suggest. Taking Ghana as a stylized agriculture-based economy with poverty most pronounced in a region with home based agricultural production, a policy mix of smoothing the real exchange rate shock and an allocation of infrastructure spending in rural areas seems to be the most promising public investment strategy to enhance growth and reduce poverty.     

The impact of public investment on private investment spending in Latin America: 1980–95

This paper investigates the theoretical and empirical links between key economic variables and private spending in Latin America during 1980 to 1995. The empirical findings of this paper directly address the complementarity hypothesis which suggests that increases in public investment spending raise the marginal productivity of private capital, thereby inducing higher rates of private investment spending. This paper also addresses the issue of whether changes in the real exchange rate (expenditure-switching policies) have a deflationary effect on the economics of Latin America. The findings in this paper make an important contribution to the ongoing debate about which policies need to be promoted to raise and sustain the rate of private capital formation in Latin America—the region's future source of employment and income creation.     

我国东、中、西部地区经济增长差异的因素分析:1952～2005年

本文采用Solow的增长核算方法,对1952～2005年间我国东、中、西部地区经济增长差异的因素进行测算和分析。分析结果表明:①我国地区经济增长主要来自于资本积累,全要素生产率增长对经济增长的贡献不大,劳动投入的贡献非常小;②资本投入增长速度差异是地区增长差异的主要决定因素,促进区域协调发展,需要国家给予中、西部地区更多投资倾斜政策,同时中西部地区自身应注重基础设施,人才环境等投资环境的培育和完善以吸引外来投资;③地区增长差异在一定程度上表现为生产率增长差异,加快西部地区技术进步和效率改善速度,提高其全要素生产率是缩小我国地区增长差异、继续推进西部大开发战略的有效途径之一。     

Agricultural Productivity and Economic Growth: Role of Tax Revenues and Infrastructures

To encourage economic growth in a developing economy, higher agricultural productivity has been believed to enhance the manufacturing sector's development, which provides the transition into industrialization. Although this positive linkage between agricultural productivity and economic growth has been judged to be incorrect, based upon the comparative advantage argument in a model of small-open economies by Matsuyama (1992), this article revisits the linkage by extending Matsuyama's model by introducing the revenue-generating effect, which is missing in his model. As agriculture is an important source of taxation in an early stage of economic development, higher agricultural productivity generates more tax revenues and facilitates spending on infrastructure. By introducing government taxation and infrastructure expenditure, we show that under proper conditions, higher agricultural productivity creates a positive growth effect via the revenue generation that dominates the negative growth effect through the comparative advantage. Moreover, introducing infrastructure expenditure may shift the manufacturing sector's original comparative disadvantage into comparative advantage, thereby enabling a trapped economy to take off and eventually industrialize. From the early stages of economic development in Japan, Taiwan, and Korea, we can quantitatively assess an obvious net positive effect of agricultural productivity upon labor allocation and economic growth.     

基础设施建设支出、结构性减税与最优政策选择

财政政策的最优政策选择问题对于国家宏观调控政策的出台具有指导意义。既往的研究忽略了利用动态一般均衡的方法探求具有双重外部性的基础设施建设支出与结构性减税支出的政策选择问题。本文利用引入基础设施建设支出和结构性减税的新凯恩斯DSGE模型,测算比较基建支出和结构性减税的政策福利效应。研究表明：具有双重外部性的基础设施建设支出不仅可以通过提高生产效率的方式促进产出,还可以通过挤入居民消费的方式加强政策福利效应。经过测算,短期的基建支出乘数大于结构性减税的政策乘数。同时,基建支出长期平均产出乘数小于结构性减税的平均产出乘数。与结构性减税政策相比,增加基建支出对于财政资金有限的政府是短期内更加有效的产出刺激政策,但在长期中,结构性减税政策不仅具有较高的政策效应,还可以从消费、劳动、投资等角度实现结构性政策目标。进一步研究发现,地区经济发展水平的不同会导致各地区的最优政策选择存在差异性：发达地区可以通过结构性税收政策解决结构性问题的同时实现长期经济增长;而欠发达地区则更应该注重运用基础设施建设为主的支出政策以促进经济增长;但随着人口逐渐从欠发达地区流出,提高欠发达地区的基建支出是否是可行之策,还需要考虑区域协调发展等诸多因素。     

Optimal government spending in an economy with imperfectly competitive goods and labor markets

This article examines the growth‐ and welfare‐maximizing government spending in an economy that is characterized by market imperfections, namely, unionization in the labor market and monopolistic competition in the goods market. To thoughtfully explore the optimal spending, two distinct scenarios where the government spending is financed by labor/capital income taxes are considered. Our analysis shows that the optimal growth‐maximizing government spending is inconsistent with the welfare‐maximizing government spending. Moreover, the growth‐maximizing/welfare‐maximizing government spending have quite different responses to distinctive market imperfections (markups in the goods and labor markets), particularly in the scenarios with distinctive financing modes. Our numerical study indicates that the growth‐maximizing and welfare‐maximizing government expenditures, in general, are more responsive to the change in the labor market friction than that in the product market friction and the growth‐maximizing government spending is more likely to be lower than the welfare‐maximizing government spending.     

交通基础设施结构对城乡收入差距的空间溢出效应研究

为探究交通基础设施作为一项公共品对缩小城乡收入差距的贡献程度,以二元经济发展理论,新古典经济学理论为基础,运用空间自相关,空间误差模型,在我国2005—2017年30个省级行政区（除西藏）的面板数据基础上,引入交通基础设施密度作为核心解释变量,从空间的视角探讨,交通基础设施对于改善城乡收入差距的贡献程度。实证结果显示：公路交通基础设施的建设有助于缩小城乡收入差距,其中,一级公路,三级公路对于收入差距存在正向溢出,二级公路存在负向溢出,高速公路影响并不明显;铁路基础设施则与之相反。结果表明：优化交通基础设施的投建结构对于缩小城乡收入差距存在重要的现实意义,随着资本边际收益不断递减以及人口红利优势的逐渐消失,合理分配交通基础设施投资支出对于推动经济增长向效率方向转型变得日益迫切。     

基于技能偏向性技术进步的经济增长动能分解

在传统Solow增长核算框架基础上引入异质性劳动投入以及技能偏向性技术进步,从而将经济增长分解为固定资本投入增长、劳动投入增长、技能结构深化、技能偏向性技术进步、中性技术进步及效率改进等五种动能。研究发现：第一,中国经济增长主要由固定资本投入以及全要素生产率增长共同驱动,其中资本投入对经济增长年均贡献率为61.64%,全要素生产率增长的年均贡献率则为35.66%,中国区别于其他中低收入国家的发展奇迹背后正是较快的全要素生产率增长;第二,即使对于高收入国家而言,资本投入仍然是主要的经济增长动能;第三,技能结构深化以及技能偏向性技术进步是全要素生产率的主要来源,二者对中国经济增长的年均贡献率分别为32.04%和21.27%;第四,资源配置效率变化是引起全要素生产率波动的主要因素,资源配置效率下降是导致2008年后中国以及大部分高收入国家全要素生产率增速放缓的主要原因。     

On public investment, long-run growth, and the real exchange rate

This paper extends the Barro (1990) endogenous growth modelwith productive government services to a two-country world withperfect capital mobility, populated by optimising agents withuncertain lifetimes. It shows that increases in government spendingon infrastructure for the home country result in higher growthrates and a terms of trade improvement. Both these effects arereversed after a point, showing that a hump-shaped curve—similarto the Barro curve, but with different properties—canbe obtained here even with lump-sum taxes. We also examine thewelfare implications of public investment policies, and characterisethe world economy's dynamics.     

Public spending and economic growth: evidence from Ghana (1970–2004)

Governments undertake expenditures to pursue a variety of objectives, one of which is economic growth. This paper examines aggregated and disaggregated expenditure on economic growth in Ghana over the period 1970–2004. Expenditure on education and health represents human capital development, while expenditure on roads and waterways captures infrastructure development. The study reveals that the aggregated government expenditure retarded economic growth. The study's findings show that expenditures on health and infrastructure promote economic growth, while those on education had no significant impact in the short run. In addition, the political economy variables?namely the nature of governance (democracy) and political instability (years of changes in government and military dictatorship)?proved significant in explaining Ghana's economic growth over the study period.     

Dynamics between government spending and economic growth in China: an analysis of productivity growth

This study investigates the dynamics between government spending and economic growth in China through influencing the productivity growth of human capital byapplying Markov switching estimates for the annual time series data of China over the period 1952–2014. Firstly, we found that the Chinese economy exists in two states including state one with low growth and state two with high growth. Secondly, the consumption spending has significantly positive effect both states, while the military spending has only positive effect in state two. Interestingly, the growth effect level of consumption spending in state two is smaller than that in state one, implying a reducing effect of total factor productivity in state two. Thirdly, the combined effects of consumption spending and military spending with human capital are state dependent. This combined effect is reduced in both states, suggesting that government spending does not improve the productivity growth effect of human capital.     

我国有效税率结构的经济增长效应：基于SVAR模型的实证研究

通过测算我国劳动、资本和消费的有效税率,以反映我国劳动收入、资本收入和消费支出的真实税收负担情况,并在此基础上构建SVAR模型来考察有效税率结构冲击对经济增长的动态影响。结果表明：消费支出有效税率和劳动收入有效税率的提高有利于投资率和经济增长率的提高,长期累积效应为正;对资本收入征税,无论在短期还是长期都不利于投资率和经济增长率的提高,长期累积效应为负。研究我国有效税率结构的经济增长动态增长效应,对政府税收政策的制定和实施时机的选择有一定的参考意义。     

Health investment,physical capital accumulation,and economic growth

This paper analyzes the effect of health investment, and hence of health capital, on physical capital accumulation and long-run economic growth in an extended Ramsey model with an Arrow–Romer production function and a Grossman (1972) utility function. The paper concludes that economic growth is related to both the health growth rate and the health level. While growth in health capital always facilitates economic growth, the gross effect of health level on the rate of economic growth depends on how it affects physical capital accumulation. If the negative effect of health on economic growth through its influence on physical capital accumulation is not taken into consideration, then health level has a positive effect on the rate of economic growth by improving the efficiency of labor production. However, since health investment may crowd out physical capital investment and thus influence physical capital accumulation, excessive investment in health may have a negative effect on economic growth. Empirical tests of these theoretical hypotheses using panel data from individual provinces of China produce results that are consistent with our theoretical conclusions.     

Public Infrastructure and the Productive Performance of Canadian Manufacturing Industries

This article examines the effects of public infrastructure on the productive performance of 12 two-digit Canadian manufacturing industries. A flexible cost function incorporating public capital infrastructure is estimated for each industry separately using annual time series data for 1961-1995. The effects of public infrastructure on productivity are measured in terms of both cost-saving (dual) and output-augmenting (primal) measures. We also investigate how public capital influences the input demand and cost structure in each industry and calculate the rate of return to public capital. The empirical results provide strong evidence of the important role public infrastructure plays in the productivity of manufacturing industries. The public capital serves as a substitute for both private capital and labor in most industries. The rates of return to public capital are significant and vary over the years.     

Total capital and economic growth

In contrast to the official estimates of gross private domestic investment and associated capital stocks prepared by the Bureau of Economic Analysis (BEA), the author presents estimates of total investment and capital, human and nonhuman, tangible and nontangible, by all sectors of the U.S. economy. Total investment is 3.1 times the BEA estimate in 1929, rising to 4.1 times in 1990. It accounts for almost half of adjusted GDP in the latter year. As hypothesized, real total capital stocks rise at about the same 2.9 percent average annual rate as real gross domestic product 1929–90, 0.1 percentage points more in the total economy and 0.2 points less in the predominant business sector. Increases in nontangible capital (mainly education, training, health, and research and development—“R&D”-) largely explain the growth in total tangible factor (capital) productivity in the whole economy. Nontangible, human capital has grown relatively faster in the business sector than in the entire economy, helping to explain its more rapid productivity advance. The author recommends that when BEA shifts to the U.N. standard system of accounts, it include nontangible and human tangible investments and capital in “satellite” accounts, as well as tangible investments for all sectors in the core accounts. This will greatly facilitate the analysis of economic growth. Presidential Address at the Thirty-Sixth Atlantic Economic Society Conference, October 7–10, 1993, Philadelphia, Pennsylvania.     

Institutions,Capital, and Growth

The international development community has encouraged investment in physical and human capital as a precursor to economic progress. Recent evidence shows, however, that increases in capital do not always lead to increases in output. We develop a growth model where the allocation and productivity of capital depends on a country's institutions. We find that increases in physical and human capital lead to output growth only in countries with good institutions. In countries with bad institutions, increases in capital lead to negative growth rates because additions to the capital stock tend to be employed in rent‐seeking and other socially unproductive activities.     

Taxing Times in Indonesia: The Challenge of Restoring Competitiveness and the Search for Fiscal Space

Indonesia’s economic growth picked up slightly in mid-2016 but remains below the level demanded by government and popular aspirations. Despite a plethora of reforms intended to increase efficiency and productivity, some policies are perverse and longstanding problems of implementation remain. The share of manufacturing has declined, the real exchange rate has appreciated, exports have dwindled, and growth has been trending downwards. The banking sector is stable but inefficient, with wide net interest margins and numerous barriers to competition. Trade protection, particularly in basic food commodities, has created high costs that weigh particularly heavily on the poor. Declining government revenues have placed increasing pressure on the public budget, even as the current administration aims to increase spending on infrastructure and welfare and to enhance productivity. In an effort to increase revenues, the government has announced a tax amnesty program and other measures. In addition, Sri Mulyani Indrawati, the new finance minister, has taken steps to cut non-essential expenditure in order to secure high spending on infrastructure and at the same time keep within the 3% budget deficit limit stipulated by law. Although the overall debt situation is not yet alarming, declining revenues and budget cuts that do not fully reflect this decline are putting pressure on increasing debt levels. The government’s high-profile tax amnesty program was the major policy initiative implemented in the second half of 2016 that aimed to relieve this pressure. Despite widespread criticism of, and scepticism about, the tax amnesty (both within and outside Indonesia), its first phase had a much higher participation rate than most independent accounts expected. Revenues raised so far through the amnesty are less than 60% of the official target, but this is actually a strong result for the short term. The bigger question, however, is whether the amnesty is a key element of a more encompassing strategy to overhaul the system of taxation and tax administration.
