省会城市的农村劳动力转移就业承载能力研究

随着城市化进程的加快、城镇人口的增加、城市规模的迅速扩张,资源消耗不断增多,环境污染日益加重,城市综合承载力对劳动力流动的瓶颈约束作用逐渐凸显,尤其经济相对发达的省会城市.因此,如何协调省会城市的可持续发展与劳动力承载数量之间的关系,便成为当今社会各界普遍关注的焦点.     

Offshoring and occupational specificity of human capital

I document that workers in newly tradable service occupations possess more occupation-specific human capital and are more highly educated than workers in previously tradable occupations. Motivated by this observation, I develop a dynamic equilibrium model with labor market frictions and specific human capital to study the labor adjustment process after a trade shock. When calibrated to match the increase in U.S. trade between 1990 and 2010, the model suggests that (1) output increases immediately after a trade shock and converges quickly to the steady state; (2) labor market institutions likely play a larger role in the adjustment process than specific human capital; (3) the short run distributional effects are small if the labor market is flexible, even in the presence of specific human capital.     

内部资本市场功能异化与公司治理

内部资本市场缓解了企业集团的融资约束,提升了投资效率,但也增加了公司治理的难度。在缺乏有效公司治理机制的情况下,内部资本市场的功能部分地被异化为经理人寻租或控股股东进行“利益输送”的渠道。本文讨论了内部资本市场功能异化与公司治理的关系,分析了内部资本市场的部分功能异化的原因,提出了治理的建议。     

Population and economic growth with human and physical capital investments

We present a two-sector endogenous growth model with human and physical capital accumulation to analyze the long-run relationship between population growth and real per capita income growth. Formal education and investment in physical capital are assumed to be two separate components of human capital production. Along the balanced growth path equilibrium, population change may have a positive, negative, or else neutral effect on economic growth depending on whether physical and human capital are complementary/substitutes for each other in the formation of new human capital and on their degree of complementarity.

Human capital,employment protection and growth in Europe

Using data for a large sample of manufacturing and service sectors in 14 EU countries, this paper shows that the value added and TFP growth rate differential between high and low human capital intensive industries is greater in countries with low than countries with high levels of employment protection legislation. We also find that such negative effect of EPL is slightly stronger for countries near the technology frontier, in the manufacturing sector and after the 1990s. We interpret these results suggesting that technology adoption depends on the skill level of the workforce and on the capacity of firms to adjust employment as technology changes: therefore, firing costs have a stronger impact in sectors where technical change is more skill-biased and technology adoption more important.     

Cross-country fiscal policy spillovers and capital-skill complementarity in integrated capital markets

The 2010 European sovereign debt crisis has renewed discussions on fiscal policy coordination. One rationale for coordination is fiscal policy cross-country spillovers. A common finding in the literature is that spillovers tend to be small in normal circumstances but can be large if monetary policy is at the zero lower bound. Orthogonal to the existing literature, we document a novel channel that generates cross-country spillovers over the medium run. We assume perfect capital markets integration and find that capital-skill complementarity can lead to large spillovers without the zero lower bound nor a large import share in government expenditures. As capital markets have become increasingly integrated in the Eurozone, the current degree of fiscal policy coordination between its members, low, may be insufficient. We also find that the smoothing benefits from a temporary rise in public debt spill over to other countries.     

Human capital and the re‐employment of retrenchment labor in urban China

The inefficiency of state‐owned enterprises, followed by the economic reform in urban China, resulted in large‐scale retrenchment during the late1990s. The laid‐off workers were middle‐aged, not well educated and had accumulated a lot of firm‐specific human capital that was unlikely to be of value in the product market. In this study, we investigate how differently human capital affects laid‐off workers’ occupation choices: self‐employment, re‐employment and remaining unemployed. Using 2002 Chinese Household Income Project and 2009 Urban Household Survey datasets, we find that although general human capital measured by education is positively related to the probability of finding a job, it is negatively associated with the probability of self‐employment. Displaced workers with more sector‐specific work experience are more likely to be self‐employed than to be employed by others. Government‐sponsored training significantly increases the likelihood of finding a job. Health is positively associated with re‐employment.     

Global capital markets,direct taxation and the redistribution of income

Standard fiscal theory suggests that taxation should be heaviest on the least mobile factors of production – for both efficiency and revenue reasons. A shift in tax burdens from capital to labour as economies become globally integrated is thus justified. This theoretical tradition (founded by Ramsay and continued by Mirrlees and Lucas) assumes by construction that profit taxes reduce investment and growth; and while sensitive to inter-generational equity, sidesteps the issue of income distribution within generations. In contrast, starting from Keynes’ critique of these assumptions and building on modern endogenous growth models, it can be shown that profit taxation is not necessarily injurious to productive investment. In practice, moreover, the effect of globalisation has not been to reduce tax rates on capital, but rather to erode the tax base itself (i.e. ‘tax evasion’). Improved information exchange between tax authorities, which is now being driven by fiscal insolvency in developed countries, would allow tax incidence to be shifted so as to improve income distribution within OECD countries. Such cooperation could also permit the replacement of the current discretionary system of fiscal transfers from rich to poor countries (‘development aid’) by equitable sharing of global capital tax revenue.     

Social capital and rural institutions in Kenya Is Machakos unique？

In Eastern Africa, the experience of Machakos has been heavily debated between Malthusians and the more optimistic Boserupians. Machakos was the epitome of overpopulation and resource degradation in the 1950s, but has since thrived. The Boserupians view Machakos as an illustration of how population growth can solve rather than exacerbate the vicious cycle of poverty and resource degradation. The question arises whether Machakos is unique. This study investigates the role of social capital in Machakos. Using principal component analysis, the authors estimate various dimensions of social capital and find significant differences between Machakos and two other Kenyan regions particularly when it comes to the formation of associations.

Growth and human capital: good data,good results

We present a new data set for years of schooling across countries for the 1960–2000 period. The series are constructed from the OECD database on educational attainment and from surveys published by UNESCO. Two features that improve the quality of our data with respect to other series, particularly for series in first-differences, are the use of surveys based on uniform classification systems of education over time, and an intensified use of information by age groups. As a result of the improvement in quality, these new series can be used as a direct substitute for Barro and Lee’s (2001; Oxford Economic Papers, 3, 541–563) data in empirical research. In standard cross-country growth regressions we find that our series yield significant coefficients for schooling. In panel data estimates our series are also significant even when the regressions account for the accumulation of physical capital. Moreover, the estimated macro return is consistent with those reported in labour studies. These results differ from the typical findings of the earlier literature and are a consequence of the reduction in measurement error in the series.      

The impact of Chinese monetary policy on co-movements between money and capital markets

From 2010 to 2017, with interest rate liberalization and capital market development in China, the impact of monetary policies on China’s financial markets underwent continuous evolution. Using the DCC-GARCH model, this study investigates the transmission process of monetary policies from the money market to capital markets (stock and bond markets). The results show that in the early stage the instability of the money and stock markets and the downturn in the bond market are primarily caused by the block of monetary policy transmission and the paucity of fund sources in the capital markets. Subsequently, the outbreak of the 2013 money shortage and the 2015 stock market crash are also closely related to monetary policies. In the later periods, the money and stock markets maintain a low degree of correlation for a long time, reducing the impact of destabilizing factors on the stock market. By contrast, with the advancement of interest rate reform and the optimization of bond market structure, the bond market is highly relevant to the money market. The central bank regulates the bond market more effectively using both traditional and innovative monetary policy tools.

Growth and social security: the role of human capital

This paper studies the growth and efficiency effects of pay-as-you-go financed social security when human capital is the engine of growth. Employing a variant of the Lucas model [Lucas, R.E., 1988. On the mechanics of economic development. Journal of Monetary Economics 22, 3–42.] with overlapping generations, it is shown that a properly designed, unfunded social security system leads to higher output growth than a fully funded one. Furthermore, the economy with an unfunded social security is efficient, while the other one is not. These results stand in sharp contrast to those obtained in models where the reason for economic growth is physical capital accumulation.     

The distributional effects of selection and capital accumulation on firm productivity under imperfect capital markets

In this evolutionary model, random shocks create differences in the rate of return on capital, while individual saving and investment behavior can reduce these differences over time. Firms with either low total factor productivity (TFP) or a low average return on capital are selected for exit, and new firms enter to take their place. As would be expected, a higher turnover rate improves TFP and reduces its variation. While we show that a higher turnover rate would result in a more positively skewed TFP distribution if exit selection is based directly upon TFP, we find that when we select firms for exit based on their average product of capital, the marginal impact of a higher turnover rate is to more negatively skew the TFP distribution. Overall, our simulations highlight the importance of considering the role selection may play in shaping the distribution of productivity when econometricians seek estimates of firm inefficiency.

Growth, distance to frontier and composition of human capital

We examine the contribution of human capital to economy-wide technological improvements through the two channels of innovation and imitation. We develop a theoretical model showing that skilled labor has a higher growth-enhancing effect closer to the technological frontier under the reasonable assumption that innovation is a relatively more skill-intensive activity than imitation. Also, we provide evidence in favor of this prediction using a panel dataset covering 19 OECD countries between 1960 and 2000 and explain why previous empirical research had found no positive relationship between initial schooling level and subsequent growth in rich countries.     

Economic development,human capital and technical change: the question of machinery revisited

A systemic element of prevailing economic growth and development is the massive introduction of machinery into the production process. The introduction of new technologies became decidedly a debated issue in economic analysis because of the dual character of technology, which simultaneously creates and destroys employment, advances and deteriorates labor skills. This paper attempts to introduce the relative issues and to assess the extent to which the introduction of machinery into the labor process improves human capital or simplifies labor skills and forms a stream of unskillful laborers.

The effect of school capital investments on local housing markets and household sorting in California

In this paper, I investigate what effect school capital investments have on housing values and household location choice in the context of the Tiebout model. This research identifies an exogenous variation in school capital investments by exploiting the lottery allocation of entitlement to an interest-free construction bond among districts in California. Although the lottery is exogenous, additional non-lottery allocation complicates identification. This paper develops an empirical model based on sample selection methods in order to create a counterfactual state in which additional non-lottery allocation would not have existed. I find that receiving the interest-free construction bond increases school capital expenditure and housing values at the district level. I view the increase in housing values as the capitalization of school capital investments. I find little evidence for the effect of the interest-free construction bond on household sorting and student’s academic outcomes.     

Sugar daddy u: human capital investment and the university-based supply of ‘romantic arrangements’

To deal with the financial hardships associated with rising college tuition, many female college students in the U.S. are turning to risqué forms of financing human capital investments, such as agreeing to potentially lucrative ‘romantic arrangements’ with older males, referred to as ‘sugar daddies,’ through the largest Internet-based club in the industry. Yet despite this recent trend, there is a relative paucity of published academic research on the economics of such behaviour. Using data from the more than 220 nationally ranked (by U.S. News & World Report’s America’s Best Colleges) colleges and universities in the U.S., presents results from both Poisson and scaled Poisson estimation suggesting that large, high-cost universities that are located in larger cities or where unemployment rates are higher lead the nation in the number of female students choosing such romantic arrangements in order to fund higher education. Moreover, those institutions that are chosen by more physically attractive female students, and those that enrol a higher percentage of female students, are also generating greater numbers of female student entrants into the sugar daddy industry. Each of these findings has implications for the human capital literature and the growing body of academic literature on the economics of beauty.     

Natural capital and quality of life: a model for evaluating the sustainability of alternative regional development paths

Natural capital contributes to the quality of life of a region in two complementary ways: first, by directly providing environmental services that cannot be imported, and second, by supplying the natural resources that, through a human controlled production process, become valuable to humans. The evolution of the combination of these two components of the quality of life determines the path of development a region takes. Environmental services also determine the ability of natural capital to regenerate itself. Ecosystems and other components of the regional natural capital produce environmental services that provide life-support functions necessary for natural capital reproduction. The destruction of this critical natural capital impairs the internal sources of improvement of the quality of life of a region, leading to a non-sustainable path of development. This article describes a model of the relationship between natural capital and quality of life that provides a stricter definition of sustainable development through explicit characterization and classification of natural capital according to its ability to produce life-supporting environmental services, by its substitutability, and by its possible reconstruction. Application of this model then shows that there are 51 possible regional development paths, only 32 of which are sustainable and only 14 of which are sustainable while also providing improvements in quality of life. Only six of these 14 sustainable development paths are attained with economic growth, however, while the other eight paths increase quality of life by increasing the production of environmental services. The model could help in the development of institutional interventions that would promote regional development paths that are sustainable.
