Factor Price Equality and Biased Technical Change in a Two-Cone Trade Model

We reconsider the effects of long‐run economic growth on relative factor prices across cones of specialization. We model economic growth as exogenous technical change. Allowing for capital biased technical change with a sector bias and for endogenous commodity prices, we find that economic growth may increase or decrease factor price differences across cones. For a neutral demand side and capital biased growth in the most capital intensive sector, we find that economic growth encourages less factor price diversity across cones.     

SECTOR‐SPECIFIC EXTERNALITIES AND STATUS PREFERENCES IN THE UZAWA‐LUCAS MODEL*

This paper shows that introducing preferences for social status based on human capital holdings modifies the finding of Gómez (2004 ) that sector‐specific externalities associated with human capital in the goods sector do not violate the optimality of the competitive economy in the Uzawa–Lucas model. The effect of an increase in the degree of sector‐specific externalities is qualitatively the same as that of an increase in the strength of the desire for status. Hence, paradoxically, a greater degree of sector‐specific externalities makes human capital accumulation more excessive from the social point of view.     

ECONOMIC GEOGRAPHY WITH TWO REGIONS: CAPITAL ACCUMULATION AND ECONOMIC STRUCTURE*

This paper proposes a compact two-region economic model with endogenous capital accumulation. The system produces one industrial commodity and service. Each region consists of one industrial sector and one service sector. The model describes the interaction between capital accumulation, the regional distribution of capital and labour, the division of labour, the capital distribution within each region, land rents, regional service prices and commodity prices over time and space. Accepting some simplifying assumptions, we show a way to integrate economic geography. equilibrium theory and neo-classical growth theory. We analyse how differences in regional resources such as land and amenities and the preference structure of the population may affect the equilibrium structure of economic geography.     

Green technological progress,agricultural modernization,and wage inequality: Lessons from China

Green technological progress (GTP) is crucial for environmental protection and economic growth in China. Over the past decades, China made huge GTP which exerts a far-reaching consequence on economic and social development. However, a paucity of research investigates the distributional effect of GTP. Meanwhile, we incorporate agricultural producer service sector into a three-sector general equilibrium model to reflect the modernization of small-scale agriculture. The agricultural producer service sector that acts as an intermediate sector can facilitate the utilization of intermediate inputs indirectly. To desalinate this process, a two-layer vertical production structure is established: parts of manufacturing goods are utilized by the service sector, outputs of which are intermediate inputs that could substitute labor in agriculture. Theoretical analysis shows that GTP increases both wage of skilled labor and unskilled labor. Nevertheless, GTP generates a greater impact on the wage of skilled labor than unskilled labor, leading to widening income disparity. Then, we examine the impact of GTP on wage inequality using a balanced panel data covering 30 provincial units in China during 2000–2019. In line with our theoretical conjecture, we find strong supportive evidences that GTP significantly widens the wage inequality.     

The quality of human capital,educational reform and economic growth

Using a general equilibrium growth model with a costly schooling process, this paper analyses the effect on economic growth of educational reform that allocates more resources to the schooling sector to raise the quality of human capital. It shows that the positive effect of improved quality on the economic growth could be offset by the reverse effect of reduced human capital formation that arises from the distortion of resource reallocation. An appropriate tax-subsidy scheme is shown to remove this reverse effect of educational reform.     

The Financial Sector and Economic Growth*

The Mankiw–Romer–Weil (1992) augmented Solow–Swan ( Solow 1956 ; Swan 1956 ) model is extended to incorporate the financial sector in this study. Distinguishing between financial capital, physical capital and human capital, the research attempts to identify, in particular, the effects of financial capital on economic growth. The effects of financial sector efficiency on economic growth are also examined. The financial sector augmented model is tested on a cross‐section of 35 economies. Strong support is found for the model.     

Tax Havens,Growth, and Welfare

This paper develops an endogenous growth model featuring tax havens, and uses it to examine how the existence of tax havens affects the economic growth rate and social welfare in high‐tax countries. We show that the presence of tax havens generates two conflicting channels in determining the growth effect. First, the public investment effect states that tax havens may erode tax revenues and in turn decrease the government's infrastructure expenditure, thereby reducing growth. Second, the tax planning effect of tax havens reduces marginal cost of capital and hence encourages capital accumulation so as to spur economic growth. The overall growth effect is ambiguous and is determined by the extent of these two effects. The welfare analysis shows that tax havens are more likely to be welfare‐enhancing if the government expenditure share in production is low, or the initial income tax rate is high. Moreover, the welfare‐maximizing income tax rate is lower than the growth‐maximizing income tax rate if tax havens are present.     

Endogenous Growth,Taxes and Government Spending: Theory and Evidence*

This paper provides a theoretical and empirical investigation of the simultaneous effects of taxes and government spending on long‐run economic growth in an endogenous growth framework. A two‐sector model is considered: one sector produces physical output and the other produces human capital. Government expenditure is divided into several categories, and several types of taxes are included. The property tax is especially interesting because it is a major source of revenue for local government. The theoretical model is estimated using annual panel data from North Carolina counties. This study finds that state‐level fiscal policies affect economic growth but county‐level fiscal policies do not.     

Factor Market Oligopsony and the Production Possibility Frontier

The authors consider a model with two final goods, one intermediate good, and two primary factors. One final good and the intermediate good are produced using primary factors, labor and capital. The other final good is produced using labor and the intermediate input. Producers of the second final good exert oligopsonistic market power on the intermediate input, which captures real world phenomena prevalent in the food processing and other manufacturing industries. If the capital/labor ratio in one final‐good sector is in between those of the intermediate‐input sector and the combined intermediate‐input and the other final‐product sectors, and if the oligopsony power is sufficiently large, the model generates results that are not adherent to the standard two‐sector Heckscher–Ohlin model. Results that deviate from the H–O model include the relationships between factor prices and commodity prices, the price–output effect, tangency between the price line and the PPF, and the curvature of the PPF.     

Economic Progress,Social Regress?

A central issue in the debate regarding the relevance of social capital is whether the decline in social embeddedness that has attended modernization over the last 40 years in the United States is as harmful as Putnam, among others, claim it to be. Critics of Putnam's thesis argue that various arms‐length institutions fulfil the roles performed by social capital thereby mitigating the negative impact of its recent decline. We develop a framework that provides insight into when such institutions may be adequate and when they might not. We find that if market (economic) and non‐market (social) interactions differ in their payoffs but are interlinked through the modernization of the economy, the optimal level of modernization in market interactions will be higher than that in non‐market interactions. Further, market supporting institutions are likely to increase the divergence between economic and social interactions since analogs for market institutions that constrain opportunistic behavior are usually nonexistent in social contexts. In this sense, economic progress may be accompanied by social regress.     

The Dynamic Process of Economic Takeoff and Industrial Transformation

This paper studies the patterns and key determinants of staged economic development. We construct a two-sector dynamic general equilibrium model populated with one-period lived non-overlapping generations, featuring endogenous enhancement in modern technology and endogenous accumulation of labor skills and capital funds. We consider preference biases toward the traditional sector of necessities, capital barriers to the modern sector, and imperfect substitution between skilled and unskilled workers. By calibrating the model to fit historic U.S. development, we find that modern technologies, saving incentives and capital scales/barriers are the most important determinants of the takeoff time. By evaluating the process of economic development, we identify that what shapes saving incentives is most crucial for the speed of modernization after taking off. We further establish that labor, capital and output are most responsive to the initial state of modern technologies, but least responsive to skill endowments, along the dynamic transition path     

Comparing approaches to valuing sectoral net investments

In the literature of comprehensive national accounts, national net investments are used to indicate dynamic welfare improvement in an economy. A well-known approach associates national net investments with the shadow value of change in stock of capital assets in an economy. Following this capital stock approach, sectoral net investments can be defined as the shadow value of change in stock of capital assets owned by a sector in an economy. An alternative approach is based on future commodity flows to a sector. This commodity flow approach associates sectoral net investments with the present value of changes in future commodity flows to a sector. In the present paper, I compare these two approaches and prove that they coincide with each other only if the future commodity flows to the sector can be attributed to current stock of capital assets in the sector alone. In empirical studies, commodity flow approach can be a better alternative if the purpose is to estimate the contributions to national net investments of a recipient of future cash flows.     

Trade liberalization,firm entry,and income inequality

This paper examines the short‐ and long‐run effects of trade liberalization via tariff reductions on income inequality in an economy, which is characterized by an imperfectly competitive urban manufacturing sector and a perfectly competitive rural agricultural sector. Tariff reductions reduce domestic output in the importable urban manufacturing sector, leading to shifts of capital from the urban sector to the rural agricultural sector. This can narrow the wage gap between skilled and unskilled labor in the short run. However, the lowered capital cost attracts new firms, and subsequently excessive entry of firms, to the urban manufacturing sector. This firm entry effect can mitigate the favorable effect of tariff reductions on wage inequality in the long run. Empirical study confirms the findings.     

Natural land productivity,cooperation and comparative development

This research advances the hypothesis that natural land productivity in the past, and its effect on the desirable level of cooperation in the agricultural sector, had a persistent effect on the evolution of social capital, the process of industrialization and comparative economic development across the globe. Exploiting exogenous sources of variations in land productivity across (a) countries; (b) individuals within a country, (c) migrants of different ancestry within a country, and (d) individuals residing in regions within a country, the research establishes that lower level of land productivity in the past is associated with more intense cooperation and higher levels of contemporary social capital and development.     

对外贸易开放、人力资本积累与企业技术创新

企业技术创新作为科技创新的核心部分,在促进经济高质量发展中的重要性日益凸显。通过构建一个包含消费部门和生产部门的两部门模型,探究对外贸易开放及其人力资本积累效应对企业技术创新的影响机制,随后基于2011-2017年中国31个省级区域的面板数据实证检验对外贸易开放、人力资本积累及二者的交互作用对企业技术创新的影响。结果显示:从整体层面来看,对外贸易开放不仅对企业技术创新产生直接影响,还会通过人力资本积累效应对企业技术创新产生间接影响;从区域异质性角度来看,贸易开放对企业技术创新产生的直接影响和间接影响存在着空间上的非均衡特征,表现为对发达的东部地区的企业影响更为明显,而对欠发达的西部和中部地区的企业影响相对较弱;从对外贸易方式来看,全样本分析表明出口贸易方式的人力资本积累效应对企业技术创新影响作用较强,而进口贸易方式的作用相对较弱。因此,应当注重不同贸易发展方式的人力资本积累效应差异及其对企业技术创新产生的影响,增强我国通过企业技术创新促进经济高质量发展的实效。     

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.     

FDI,SECTORAL OUTPUT AND REAL EXCHANGE RATE DYNAMICS UNDER FINANCIAL OPENNESS

This paper adopts an alternative approach to the study of the impact of capital inflow on the real exchange rate by foremost, analysing the effect of FDI inflow on the ratio of tradables to nontradables, and then estimating the relationship between the tradable‐nontradable ratio and the real exchange rate, while accounting for the role of financial openness. Based on data for a group of developing countries, the findings show that an increase in FDI inflow is associated with a decrease in the tradable‐nontradable ratio, and that an increase in the tradable‐nontradable ratio leads to a depreciation of the real exchange rate; this effect being greater with an increase in financial openness. This suggests that an increase in FDI inflow could result in an expansion of the nontradable sector, which would be associated with a greater appreciation of the real exchange rate under a higher level of financial openness.     

Climate threshold,financial hoarding and economic growth

We use an iterative finite difference method to establish theoretical models that reflect the relationships among climate threshold, financial hoarding and economic growth. We build a simultaneous equations model to conduct an empirical analysis based on China’s statistical data from 1979 to 2012. Our study yields the following results: China’s climate threshold has shown a zigzag-shaped rising trend since 1979; the main reasons for the rapid expansion of financial hoarding were high savings rate, savings leakage, higher marginal efficiency of financial hoarding compared to capital efficiency or higher internal creativity of the financial sector; there were positive cumulative effects between financial hoarding and economic growth, which were significantly inhibited by climate threshold; the climate threshold had discrepant influences on different industries. To achieve a balanced economy, more money should be invested in the real sector to appropriately reduce the rate of savings leakage; the financial sector should move from scale expansion to service efficiency improvements to increase its marginal contribution to the economy and to enhance capital efficiency; the real sector should improve technological innovation and speed up the adaptive adjustment in climate-sensitive industries to move from economic growth to advanced development.     

The cost of capital,finance and high‐tech investment

Investment is the most volatile component of aggregate demand and it is often considered central to business cycles fluctuations. The responsiveness of business investment to changes in its price is thus crucial to our understanding of economic activity. In spite of the key role played by the user cost of capital in economic analysis, there is little empirical support for the existence of substantial user cost elasticity. However, most of the evidence to date is based on aggregate user cost data, which may have introduced downward biases in the estimated user cost. This paper contributes to the literature by constructing a disaggregated, industry‐specific micro user cost variable and focusing on a special class of firms – the high‐tech firms. To provide a benchmark for the results, the user cost estimates for the high‐tech sector are compared with those for the rest of the manufacturing sector. The results suggest that there is little response of investment to variations in its user cost. The findings also suggest that high‐tech firms’ investment behavior is not, after all, that different from the rest of the manufacturing sector.     

Regulations and Technology Diffusion: Cross Subsidies and Digital Infrastructure Creation

Using contemporary historical data, the analysis has examined the impact of cross‐subsidization on technology diffusion within telecommunications networks for local exchange sector telecommunications firms in the United States for the years 1995 to 2000. Firms obtaining greater cross‐subsidies engage in greater technology diffusion via network modernization using digital technologies. Contingent on the institutional setting, cross subsidies have risen. These amounts have been put to relevant use in the diffusion of technology via deployment of digital infrastructure. The principles of subsidization are considered negatively as they have presumed anti‐competitive consequences. In technology diffusion they have played a positive role, as the evidence shows. From a radical subjectivist perspective, cross subsidies generate financial capital for firms, which permits them to deploy high quality technology investments such as broadband and these investments can be used for entrepreneurial experiments in providing several customer services.
