The Relative Earnings from Self and Paid Employment: A Time-series Analysis for the UK

We investigate the determinants of variations in the reported relative earnings of self-employed and paid-employed workers in the United Kingdom, focusing in particular on the significant decline which has taken place since 1980. We find that the main factors behind this decline have been the rise in the rate of self-employment itself and a reduction in the level of capital per self-employed worker; effects which we associate with a decline in the quality of the average self-employed business. Changes in the tax rates on income and in the sectoral composition of GDP helped to reduce the scale of the decline in self-employment relative earnings to some degree.     

Sunk capital,unions and the hold-up problem: Theory and evidence from cross-country sectoral data

In this paper we study the hold-up problem by considering the effect of union bargaining power on the level of investment per worker across sectors characterised by different levels of sunk capital investment. We develop a search and matching model with heterogeneous sectors and ex-post collective wage bargaining and test the predictions of the model using a difference-in-difference approach on manufacturing sector data in a set of OECD countries during the period 1980–2000. We find that union power reduces investment per worker particularly in sunk capital intensive industries. We refine our empirical analysis showing that the underlying hold-up problem is exacerbated when strikes are not regulated after a collective contract is signed and there is no arbitration, while the presence of social pacts may sustain cooperative equilibria that alleviate the hold-up problem. Our results are robust to a series of controls and possible endogeneity of union power.     

Is foreign trade important for regional growth? Empirical evidence from Portugal

The aim of this study is to investigate whether openness, export shares or trade balances affect regional growth in Portugal. Human capital is also considered as a conditional factor to growth, expressed by the rate of success in high school education. Thus, we analyse whether the combination of international trade and human capital is relevant to explain regional growth in Portugal and how it affects the convergence process between regions. In the empirical analysis, interaction terms are introduced to explore the existence of different performances between regions of the Littoral and the Interior. As an alternative to the traditional approach that considers the population growth rate, we include the share of sectoral employment aiming to capture labour specialisation in the main sectors of economic activity and measure its impact on regional growth.The empirical analysis estimates the conditional convergence model of the Barro's type, applied to the Portuguese NUTS3 regions for the period 1996-2005. The GMM estimation approach applied to regional panel data reveals that factors associated with external trade, human capital and sectoral labour share (especially of the industrial sector) are relevant to explain regional growth and convergence in Portugal.     

Factors of production,productivity, institutions,and development: Evidence from Brazil

The economic growth and development literature emphasizes that investment in technology and physical and human capital is essential for achieving higher levels of development. Political and economic institutions are also relevant in this process. With a sample of 5,503 Brazilian municipalities, this study carries out a development accounting exercise and measures the effects of institutional quality on per capita gross domestic product (GDP), physical capital intensity, human capital stock, and productivity. The empirical results indicate that institutional quality affects GDP per capita mainly through human capital accumulation and total factor productivity.     

Public and private inputs in aggregate production and growth: a cross-country efficiency approach

In a cross section of OECD countries, we replace the macroeconomic production function by a production possibility frontier, total factor productivity being the composite effect of efficiency scores and possibility frontier changes. We consider, for the periods 1970, 1980, 1990 and 2000 one output – GDP per worker – and three inputs – human capital, public physical capital per worker and private physical capital per worker. We use a semi-parametric analysis, computing Malmquist productivity indexes, and we also resort to stochastic frontier analysis. Results show that private capital is important for growth, although public and human capital also contribute positively. A governance indicator, a nondiscretionary input, explains inefficiency. Better governance helps countries to achieve a better performance. Nonparametric and parametric results coincide rather closely on the movements of the countries vis-à-vis the possibility frontier and on their relative distances to the frontier.     

Determinants of investment and innovation expenditure in Polish manufacturing industries

This article analyses determinants of sectoral R&D and innovation expenditure as well as investment in Polish manufacturing industries in 1994–2004. The estimated coefficients for user cost of capital are generally in line with the neoclassical model of investment, except for R&D intensity. The latter are primarily discouraged by systemic uncertainty. The rate of growth of sales is not a prominent determinant of investment and innovation expenditure. Market concentration coupled with uncertainty has a damaging effect on physical capital investment but it promotes R&D expenditure and leaves innovation intensity unaltered.     

Industrial development in Malaysia and Singapore: Empirical analysis with multiple‐cone Heckscher–Ohlin Model

This paper employs the multiple‐cone Heckscher–Ohlin model to analyze industrial development in Malaysia and Singapore. In particular, we focus on industrial upgrading along with capital accumulation as a key determinant for the cross‐country difference in production technology and income. By pooling two countries’ data on factor endowment and sectoral output in manufacturing from 1990 to 2008, we estimate the common industrial development paths of the two‐cone Heckscher–Ohlin model, the Rybczynski linear relationship between capital–labor ratio and sectoral output per capita. Our results demonstrate that, after controlling for quality of workers (by educational attainment), the two countries resided in different cones during our sample period, implying that Singapore succeeded in accumulating capital steadily with the support of foreign investment and upgrading its industry mix to make it more capital‐intensive. The separation of cones is also consistent with the observed gap in gross domestic product per capita between the two countries. Furthermore, we implement a factor‐augmenting productivity test to see the gaps in efficiency of capital and human‐capital‐augmented labor and confirm no significant difference between the two countries.     

资本性支出分权、公共资本投资构成与经济增长

本文建立一个财政分权框架下的两部门内生增长模型,从理论上分析最优公共资本投资配置及其对经济增长的影响,并以我国全国和省份经济数据为基础对本文理论分析进行实证检验。分析表明,我国公共资本投资构成不尽合理,全国和地方公共物质资本投资比重明显偏低;中央和地方政府间公共资本投资事权划分也欠妥,资本性支出分权水平明显过高。这些结论对于我国今后财政政策的合理调整、政府间事权的科学划分具有重要意义。     

我国三大经济圈制造业结构变动趋向分析——对环渤海、长三角和珠三角的一项实证研究

基于1988—1997年和2000—2011年这两个时段环渤海、长三角和珠三角三大经济圈各省市分行业面板数据,从结构变化的资本集约度角度考察制造业结构变动的趋向。实证结果表明,1988—1997年时段,经济圈中除广东省外,绝大多数省市制造业劳动力要素是从劳动密集型产业向资本密集型产业转移的,而2000—2011年时段,不少省市的制造业结构呈劳动密集型化变动特征。而且,三大经济圈制造业结构向资本密集型调整在区域上由北向南递减,而向劳动密集型调整则由南向北递减。进一步的研究显示,三大经济圈制造业结构趋向于劳动密集型化的现象背后,存在制造业向技术密集型产业调整的明显趋势。另外,对制造业人均累积资本进行分解后发现,制造业结构变化本身并不是制造业人均累积资本变化的决定性因素;2000年以后三大经济圈制造业人均累积资本的提升差异较大,且劳动力要素在部门间的流动已开始抑制整体制造业人均累积资本的增加。     

Modelling Social Infrastructure and Economic Growth

This paper develops a growth model with a public sector and a human capital sector to explore the impact of social infrastructure on investment in physical capital, the accumulation of skills, output, and consumption. We show that the implications of the model are consistent with the empirical observations of Hall and Jones (1999 ). Economies where government policies and institutions encourage production over diversion have a larger 'stock' of social infrastructure, conditional on population size and sophistication of diversion technologies, which raises output per worker by increasing the extent of participation in market, rather than diversive, activities. The magnitude of these effects depends on economic agents' inherent propensity for rent-seeking. In addition, economies with unstable governments may suffer from an under-provision of social infrastructure and, consequently, have reduced levels of capital and output per worker.     

Economic Growth and Wage Stagnation in Peru: 1998–2012

From 1998 to 2012, the Peruvian economy exhibited rapid growth. Moreover, the composition of the labor force improved in terms of education and experience, two variables that are typically associated to higher human capital. The average worker in 2012 had a higher level of education and was one and a half years older than in 1998, reflecting the impact of the demographic transition. However, the average real wage was roughly constant. We show that a decline in the wage premium for education, and to a minor extent for experience, is responsible for the lack of growth in the average real wage. Had these two premia remained constant throughout the period of analysis, average labor earnings would have increased by about 2.6% per year, of which 0.7 percentage points are accounted for by the changes in the composition of the labor force in terms of age and education. We explore the role of the relative supply of workers with different levels of human capital as an explanation for the decline in the wage premium for education. Finally, we analyze the implications of these findings for some macroeconomic variables, as earnings and wage inequality, the labor share and total factor productivity.     

Growth effects of FDI in 80 developing economies: the role of policy reforms and institutional constraints

Theoretical and empirical literatures have identified several channels through which foreign direct investment (FDI) influences economic growth. This paper examines the impact of FDI on economic output growth per worker using aggregate production function augmented with FDI inflows, economic policy reforms and institutional constraints. The paper covers 80 developing countries over the period 1980–2006. We use panel data and employ fixed, random effects and GMM methods for estimation. Our results highlight the importance of FDI, policy reforms and institutional development for growth in developing economies. Finally, we demonstrate that irrespective of reforms and institutions, an increase in FDI affects output growth positively.     

A Spatial Econometric Analysis of Cultural Dimensions,Technology Knowledge and Economic Growth

Using data from 65 countries over the period 1980–2003, this paper investigates the role that cultural dimensions play in the process of technological change, innovation and adoption and consequently on the steady state level of output per worker and its growth, using spatial econometrics techniques to account for spatial dependence between countries. Initial findings indicate that differences across cultural dimensions act as a leveling effect but not as long run growth determinants. In addition, when controlling for physical and human capital accumulation, culture plays a much smaller role in explaining differences in income per capita than initially thought, with little effect on output per worker growth along the transitional dynamics path. Spatial econometric considerations are relevant in explaining differences across rates of growth of per worker output, but not in terms of steady‐state levels of income.     

Energy and capital inputs: cornerstones of productivity growth in Mexico: 1965–2004

Gross domestic product per remunerated labor (GDP/L), known as the Mexican average productivity, grew very rapidly from 1965 to 1979; it increased at an average annual rate of 3.7%. But from 1979 through 2004, productivity stagnated with an average annual growth rate of only 0.19%. The hypothesis is that from 1965 through 1979, productivity increased rapidly because of concomitant growth in the utilized capital and energy per worker and the improvements in technology. After 1979, the productivity growth came to a standstill because of a slowdown in investment and stagnation in the utilized capital and energy per worker due to the sharply rising energy prices. The tool chosen to test this hypothesis is an aggregate Cobb-Douglas production function characterized by technical change embodied in the gross investment in new machinery and equipment. The estimation of this model shows energy as a cornerstone of productivity growth independent of capital and new technology.     

Convergence of labor productivity across the US states

Most studies of labor productivity convergence among US states base their analyses on state-level GDP per worker. Such aggregated analysis may hide important information about the role of sectors, and changes in the sectoral composition of these economies, in explaining economy-wide convergence results. Using highly disaggregated data for the period 1987–2015 from the US Bureau of Economic Analysis, we examine sectoral unconditional convergence in labor productivity in the US states. Our results demonstrate a general slowing down in the rate of convergence of labor productivity in the latter years of this period. The sectoral analysis also indicates that manufacturing was the primary driver of convergence during the 1987–1997 period, which had the highest rate of convergence; the role of this sector, however, has diminished in recent years. Several factors—such as the decline in interstate migration, rising housing costs in major cities, agglomeration, and structural changes in the US economy that have reduced the role of manufacturing—may have contributed to the rise in the labor productivity differential among US states.     

HUMAN CAPITAL: DETERIORATION AND NET INVESTMENT

The current practice in national accounting is to exclude from national product investment in schooling and on-the-job training, except for direct costs of schooling which are included in consumption. Foregone earnings, which form the major part of investment in human capital, go unrecorded.
Much is to be gained in consistency and analytical clarity by treating human capital like physical capital in national accounting. Estimating the amount of foregone earnings net of deterioration, that is, net investment, is a step in this direction.
Using the framework of the life-cycle hypothesis of earnings, and assuming declining-balance deterioration of human capital, estimates of deterioration rates in respect of American males by race and education level are computed for 1960. Every such d is, however, the minimum consistent with the respective costs and benefits profile. Hence an upper limit d is assumed. The model generates for each costs and benefits profile and in respect of either d , a year-by-year series of net investment in human capital. These are used to obtain two estimates (which turn out to be close to each other) of aggregate net investment in American white males in 1960. On the basis of these estimates, aggregate net investment in human capital is found to be about equal to net investment in physical assets (including consumers'durables).
It is also found that the Denison method of estimating the contribution of the increase in human capital to economic growth understates this contribution by a ratio approximately equal to net investment in on-the-job training to returns to human capital. This was about 16 percent in 1960.     

科技型中小企业R&D投资、人力资本投资与企业成长路径的关系

基于科技型中小企业成长的特点,将人力资本与技术资本涵盖于知识资本的范畴,在动态演化的理论框架中,构建了影响科技型中小企业演化路径的指标体系,并首次运用混合截面数据对科技型中小企业知识资本与企业演化路径的关系进行了实证研究。研究表明：在满足一定条件下,人力资本与企业成长路径变迁之间呈正相关关系,其中,研发人员比例具有显著的经济意义。同时,R&D投入对企业倾向于跳跃式突变成长有显著的正向影响,而非R&D投入与其存在负相关关系,但在控制了行业特征之后,传统制造业R&D投入效果较高科技行业更为显著。这一结果从另一侧面说明了行业特征对企业演化路径和策略选择的重要性。另外,我国科技型中小企业在成长路径选择中不存在区域比较优势。     

Human capital, economic growth, and regional inequality in China

We show how regional growth patterns in China depend on regional differences in physical, human, and infrastructure capital as well as on differences in foreign direct investment (FDI) flows. We also evaluate the impact of market reforms, especially the reforms that followed Deng Xiaoping's “South Trip” in 1992 those that resulted from serious hardening of budget constraints of state enterprises around 1997. We find that FDI had a much larger effect on TFP growth before 1994 than after, and we attribute this to the encouragement of and increasing success of private and quasi-private enterprises. We find that human capital positively affects output and productivity growth in our cross-provincial study. Moreover, we find both direct and indirect effects of human capital on TFP growth. These impacts of education are more consistent than those found in cross-national studies. The direct effect is hypothesized to come from domestic innovation activities, while the indirect impact is a spillover effect of human capital on TFP growth. We conduct cost-benefit analysis of hypothetical investments in human capital and infrastructure. We find that, while investment in infrastructure generates higher returns in the developed, eastern regions than in the interior, investing in human capital generates slightly higher or comparable returns in the interior regions. We conclude that human capital investment in less-developed areas is justified on efficiency grounds and because it contributes to a reduction in regional inequality.
