Differential Migration Prospects,Skill Formation,and Welfare

This paper develops a one sector, two‐input model with endogenous human capital formation. The two inputs are two types of skilled labor: “engineering,” which exerts a positive externality on total factor productivity, and “law,” which does not. The paper shows that a marginal prospect of migration by engineers increases human capital accumulation of both types of workers (engineers and lawyers), and also the number of engineers who remain in the country. These two effects are socially desirable, since they move the economy from the (inefficient) free‐market equilibrium towards the social optimum. The paper also shows that if the externality effect of engineering is sufficiently powerful, everyone will be better off as a consequence of the said prospect of migration, including the engineers who lose the migration “lottery,” and even the individuals who practice law.     

The transition to a globalized economy: Poverty,human capital and the informal sector in a structuralist CGE model

Recent econometric evidence suggests that trade liberalization has an elusive relationship to growth and income distribution. This paper provides an explanation for these results via numerical simulations of a dynamic structuralist CGE. The conclusion is that if families become too poor to finance human capital accumulation, or the state too stingy to supply it at a reasonable cost, exports of skill-intensive goods can become uncompetitive and the transition to openness may involve increasing poverty, unemployment and stagnation. The model design incorporates an informal sector as well as accumulation of human capital. The paper simulates two trajectories, a “green” path in which per capita income grows steadily with a rapid rate of human capital accumulation and a reduction in the level of economic informality. A second, or “red” path is also possible, however, with a growth rate that is much lower, an expanding informal sector and an inadequate rate of human capital formation.     

HUMAN CAPITAL ACCUMULATION,HOME PRODUCTION AND EQUILIBRIUM DYNAMICS*

In this paper, we construct a three‐sector endogenous growth model in which long‐run growth is propelled by human capital accumulation. We show that although the addition of a home sector to the standard two‐sector endogenous growth model preserves the well‐behaved balanced growth equilibrium properties, it generates new transitional dynamics around the balanced growth path. It is shown that, when there is a positive shock to physical capital, our model is more likely to exhibit paradoxical growth than are standard multisector endogenous growth models that exclude home production. Our analysis adds new results to those from the related literature on leisure.     

The Return to Capital and Convergence in a Two Sector Model of Endogenous Growth

This paper obtains a simple algebraic derivation of the transitional dynamics of a two-sector endogenous growth model. This paper finds that the return to capital and the growth rate of output fall over time on the transition path if the initial ratio of physical capital to human capital is lower than the steady state level. It also shows that two sector endogenous growth models are consistent with the evidence on conditional convergence found by Barro (1991) and Mankiw, Romer, and Weil (1991). Neoclassical growth models and endogenous growth models are impossible to distinguish in terms of the falling rate of return on capital or in terms of conditional convergence. [O41]     

On the Growth Implications of Foreign Aid for Public Investment Co-Financing

In this paper we present an endogenous growth model with foreign transfers for public capital formation in order to analyze the implications for growth maximization when the public sector in recipient countries co‐finances investment projects. Our main innovation is to show that, first, there is a unique growth‐maximizing absorption rate of funds that decreases with the co‐financing ratio and, second, that high amounts of assistance may be an impediment to growth due to the excess domestic taxation required to co‐finance investment projects. We then derive a policy rule for designing the growth‐maximizing co‐financing share under a given level of assistance. Finally, we also highlight some implications for EU regional policies, which aim at fostering growth in poorer EU countries by co‐financing public capital formation.     

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.     

Industrial Targeting and Non‐shiftable Capital in the Harris–Todaro Model*

This paper shows that, in the 2 × 3 sector‐specific capital Harris–Todaro model, capital growth owing to either domestic or foreign investment always enhances the welfare of the country (i.e. non‐immiserizing), and this result of non‐immiserizing foreign investment holds regardless of initial holdings of foreign capital; the policy of industrial targeting via capital investment is more effective vis‐à‐vis the (neoclassical) 2 × 2 mobile‐capital Harris–Todaro model or the Heckscher–Ohlin model; in contrast to the recent generalization by Marjit and Beladi (2003 ), capital growth cannot be immiserizing in the present model, even if it destroys the “envelope theorem.”     

OPTIMAL TRANSITION DYNAMICS IN THE LEONTIEF TWO‐SECTOR GROWTH MODEL WITH DURABLE CAPITAL: THE CASE OF CAPITAL INTENSIVE CONSUMPTION GOODS*

We present results on undiscounted optimal policies in the Leontief two‐sector growth model with durable capital. Unlike the results with a labour intensive consumption goods sector, we show that a monotonic optimal programme is only one special case out of many richer possibilities of transition dynamics. Depending on the initial capital stock, and a key parameter ζ that could be interpreted as a marginal rate of transformation of capital between today and tomorrow, an optimal programme may converge to a period‐two cycle; and even when it converges to the golden rule stock, it can do so (damped) cyclically or with a “jump”.     

Human capital formation,learning by doing and the government in the process of economic growth

We present an endogenous growth model with human capital and learning by doing. Human capital is not an input factor in the production process of final output but it affects the ability to build up knowledge capital as a by‐product of cumulated investment (learning by doing). Human capital is formed in the schooling sector that is financed by the government. The government may run into debt but obeys the inter‐temporal budget constraint. The article analyzes the structure of the model and studies the effects of different budgetary policies as regards the balanced growth rate, transition dynamics and with respect to welfare.     

Endogenous human capital formation,distance to frontier and growth

We examine human capital's contribution to economy-wide technological progress through two channels – imitation and innovation – innovation being more skill-intensive than imitation. We develop a growth model based on the endogenous ability-driven skill acquisition decision of an individual. It is shown that skilled human capital is growth enhancing in the “imitation-innovation” regime and in the “innovation-only” regime whereas unskilled human capital is growth enhancing in the “imitation-only” regime. Steady state exists and, in the long run, the economy converges to the world technology frontier. In the diversified regime, technological progress raises the return to ability and generates an increase in wage inequality between and within groups – consistent with the pattern observed across countries.     

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.     

Crossing Hubbert’s peak: Portfolio effects in a growth model with exhaustible resources

This paper elaborates a two-class growth model with an exhaustible resource (“oil”) and an alternative technique (“solar”). Bequest savers accumulate wealth, consisting of capital and oil, saving a constant fraction of their end-of-period wealth. The price of oil obeys Hotelling’s rule. Rising oil prices and the depletion of oil supplies create portfolio effects on the accumulation of capital. When growth is constrained by an exogenously increasing labor force, these wealth effects express themselves in changes in the distribution of income, which first shifts toward profits and then shifts back toward wages as the oil stocks approach depletion. When growth is constrained by capital (the labor force is endogenous), the portfolio effects express themselves in changes in the rate of capital accumulation, which first declines and then rises sharply as the oil stocks approach depletion.     

Endogenous technological progress in a multi-sector growth model

This paper presents an endogenous growth model driven by human capital, where human capital can be allocated across three sectors: the production of the final consumption good, the educational sector and the production of technological capital (in the form of knowledge or ideas). In our model, which also includes public expenditure and population growth, labor augmenting technical progress is endogenous and this enriches the transitional dynamics of the economy. With respect to ideas-based growth models, we assume knowledge is produced according to a neoclassical technology, combining ideas and human capital. Such an assumption is motivated by empirical works showing the existence of significant decreasing returns in the creation of ideas at the aggregate level (as Kortum, 1993; and Pessoa, 2005) and of the weak relationship between some inputs of the knowledge production process (as the number of researchers) and the total factor productivity growth rate (as Jones, 2002). Under some general conditions, this economy exhibits the existence of a steady state equilibrium and an unstable multidimensional manifold. Numerical examples are provided to show the existence of stable arms.     

CONFORMISM AND STRUCTURAL CHANGE

Using a simple, multisector model of endogenous growth, we show that commodity‐specific consumption externalities can be a source of structural change. When the degrees of consumption externalities are different between goods, each sector grows at a different rate. However, the aggregate economy exhibits balanced growth in that capital stock and expenditure grow at the same constant rate. A three‐sector version of our model may reconcile Kaldor's stylized facts with empirically plausible profiles of industrial structure transformation.     

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.     

论体制转轨的动态过程——非国有部门的成长与国有部门的改革

本文试图将中国经济体制转轨所取得的成就和所面临的问题 ,放在一个简化了的动态模型中加以系统地分析。文章指出 ,动态地看 ,体制转轨的根本问题就是非国有经济比重的不断提高和经济的所有制结构的转变。在非国有经济的增长率高于国有经济的增长率的“基本假定”下 ,体制转轨的最重要的问题首先不是改革国有经济 ,而是发展非国有经济。这不仅是由于非国有经济的发展支撑着经济的增长和市场体制的形成 ,而且也是由于它创造出使国有经济得以改革的更有利的条件。国有经济改革的重要性主要在于 ,它们若不改革 ,就还要占用大量资源 ,而且是要从非国有经济转移资源作为事实上对国有经济的补贴。这种补贴在过去一个时期主要体现在银行坏债、资本市场上的“坏股”、非国有经济的“综合税赋”事实的不断提高 ,等等 ,现在也体现在政府债务增大。正因如此 ,尽管中国目前并不面临金融危机 ,但必须加快国有企业和国有银行控制的金融体制的改革进度 ,以保证非国有经济能持续发展下去 ,保证整个体制转轨过程的持续进行而不被某种危机所打断。     

Government size and economic growth in an endogenous growth model with rent‐seeking

We explore the relationship between government size and economic growth in an endogenous growth model with human capital and an unproductive capital which facilitates rent‐seeking. With exogenous as well as endogenous time discounting, we find a non‐monotonic relationship between the size of government and economic growth. We find that with very high (low) discounting, there is a unique low (high) growth equilibrium, regardless of the size of government. For the intermediate range of discounting, there are multiple equilibria and the growth outcome depends on the size of government. With endogenous time discounting, the growth outcome is path dependent and depends on the level of inherited human capital. However, there is only one stable growth regime and the economy endogenously switches to it. When the institutional constraints on rent‐seeking are not extremely high, the stable regime is the one in which there is a high‐growth equilibrium for a smaller size of the government and for larger size, both the high‐growth and the low‐growth equilibrium coexist. When the institutional constraints on rent‐seeking are extremely high, there exists only a unique high‐growth equilibrium irrespective of the size of government. Furthermore, economies with bigger size of the government and/or with poor quality institutions will take longer to endogenously switch to this stable growth regime.     

HUMAN CAPITAL DISTRIBUTION,GROWTH AND TRADE

Distribution differences in human capital matter for a country's growth and trade. While the existing literature considers only the diversity difference in talent distribution, we argue that the kurtosis difference is also an important factor. In a two‐sector equilibrium growth model, where the production function is supermodular for the consumption‐good sector and submodular for the R&D sector, we prove that the diversity effect and kurtosis effect are opposite to each other. A country endowed with more diverse but leptokurtic talent distribution may have lower growth rate and import submodular goods, opposite to the conventional result from considering only the diversity difference.     

信任及其解释:来自中国的跨省调查分析

“信任”被普遍认为是除物质资本和人力资本之外决定一个国家经济增长和社会进步的主要社会资本。华人社会在许多跨文化研究中被认为是低信任度的社会 ,而在国内 ,许多学者已用“信任危机”概括人与人关系的现状。本文试图通过中国跨省的信任调查数据 ,揭示信任对一个地区的经济绩效 ,例如企业规模、企业发展速度、引进外资等的影响 ,进一步分析影响信任的因素。我们的发现表明 ,一个地区能否被人们所信任与地域文化并不紧密相关 ,更重要的是跟人们之间的交易被重复的可能性、交易的发达程度、教育水平等因素有关。这些证据支持了经济学理论中关于重复博弈导致信任的基本假说。     

Sources of Canadian economic growth

We apply modern ideas‐oriented growth accounting, based on the semi‐endogenous growth theory of Jones (2002), to compare the sources of Canadian and US economic growth between 1981–2014. This framework allows us to distinguish between transition dynamics and steady state growth as well as quantify their respective contributions. We find that the bulk of the 1.1 percentage points total average Canadian growth rate of output per hour has been due to transitional factors, mainly capital intensity and domestic human capital growth driven by educational attainment. The growth in excess ideas (total ideas growth minus steady state growth) has contributed a small share of 0.06 percentage points. Two features stand out in comparison to the US growth experience over the same period. First, over a full percentage point of the average US growth of 1.64% is due to excess ideas growth. Second, the “constant growth view” that reconciles large sources of transitional growth with relatively stable average growth is not supported in Canada. We estimate a relatively low elasticity of output with respect to world research effort as the reason behind the small share of R&D‐oriented sources of Canadian growth.
