Assets,activities and income generation in rural Mexico: factoring in social and public capital⋆

In recent years, there has been increasing emphasis in the rural development literature on the multiple income‐generating activities undertaken by rural households and the importance of assets in determining the capacity to undertake these activities. Controlling for the endogeneity of activity choice and applying Lee's generalisation of Amemiya's two‐step estimator to a simultaneous equation model, household returns to assets from multiple activities are explored for the Mexico ejido sector. To incorporate the multiple variables representing social and public capital into the analysis, factor analysis is used. The results indicate that the asset position of the household has a significant effect on household participation in income‐generating activities and returns to those activities. Furthermore, the inclusion of measures of social and public capital into the analysis show that these assets play an important role in income‐generating activities and that the influence is dependent on the type of social and public capital as well as the particular activity.     

Defined benefit versus defined contribution pension plans: How are the interests of employees and the public best served?

Prior to the enactment of the Employee Retirement Income Security Act of 1974 the rate of formation of defined benefit retirement plans exceeded the rate of formation of defined contribution retirement plans. Following its enactment the trend has been reversed. This article reviews the development of public policy with respect to privately sponsored retirement benefits, takes note of the legislatively mandated regulatory distinctions between defined benefit and defined contribution plans, outlines the distinctions between the plans from the perspective of plan sponsors versus plan participants, and questions the appropriateness of the movement away from defined benefit plans in terms of public policy objectives regarding retirement income security.     

Free trade, factor returns, and factor accumulation

A model of development is studied in which physical capital and unskilled labor are good substitutes, and skilled labor is complementary to the resulting aggregate. Growth in a closed economy is compared with two open regimes. Inflows of physical capital only reduce the interest rate and raise both wage rates. The skilled wage rises more sharply, however, increasing the skill premium and accelerating human capital accumulation. Full integration with a larger and more developed neighbor also reduces the interest rate and raises both wage rates, but in this case the skill premium falls and human capital accumulation changes very little.     

Predation and accumulation

This article incorporates the economic theory of predation into the theory of economic growth. The analytical framework is a general-equilibrium model of the interaction between two dynasties: a potential predator and its prey. We find that the rate of accumulation of capital and the security of property are positively related only for generations of the prey dynasty that tolerate predation. Generations of the prey dynasty that choose to deter predation, even though their property is perfectly secure, accumulate productive capital more slowly than the preceding generations that tolerated predation.     

External adjustment

Gross stocks of foreign assets have increased rapidly relative to national outputs since 1990, and the short-run capital gains and losses on those assets can amount to significant fractions of GDP. These fluctuations in asset values render the national income and product account measure of the current account balance increasingly inadequate as a summary of the change in a country's net foreign assets. Nonetheless, unusually large current account imbalances, especially deficits, should remain high on policymakers' list of concerns, even, for the richer and less credit-constrained countries. Extreme imbalances signal the need for large and perhaps abrupt real exchange rate changes in the future, changes that might have undesired political and financial consequences given the incompleteness of domestic and international asset markets. Furthermore, of the two sources of the change in net foreign assets—the current account and the capital gain on the net foreign asset position—the former is better understood and more amenable to policy influence. Systematic government attempts to manipulate international asset values in order to change the net foreign asset position could have a destabilizing effect on market expectations. JEL no.

International capital market integration: Implications for convergence, growth, and welfare

This paper studies the effects of international capital market integration on welfare and the speed of adjustment in a two-region endogenous growth model. Monopolistic firms undertake research and development (R&D) to improve their productivity level. National and international knowledge spillovers affect the returns to R&D. The two countries differ with respect to the initial productivity level and R&D capability (which is a proxy for human capital and structural policies). Long-run productivity gaps are determined by the difference in R&D capability. Over time, there is conditional convergence in productivity levels. The speed of convergence is larger with integrated international capital markets than without. Long-run gaps in consumption levels are larger in the former situation than in the latter. Capital market integration harms (benefits) the leading (lagging) region if domestic spillovers are more important than international spillovers and differences in R&D capabilities are small.The authors research is supported by the Royal Netherlands Academy of Arts and Sciences.

Learning-by-doing versus Schooling in a Model of Endogenous Growth

A two sector model of learning-by-doing measured by means of production aggregated over time and of human capital accumulation in a schooling sector is presented. Time utilization is rival between schooling and learning-by-doing. Depending on the sum of elasticities of the accumulated factors (i.e., of production experience and educational human capital) in both sectors, a situation with or without endogenous growth results. Dynamic optimization of the choice between leisure and working and of the division of human capital between education and production is executed. Transitional dynamics are analyzed for a Cobb-Douglas example and a numerical simulation is performed.JEL classification: C61, D90, O41.Acknowledgements The author would like to thank Eric C.

公司转投资的规制分析

转投资有诸多效益功能。其可能的弊害分为两个层次,表层次上的弊害在于转投资增加了股东和债权 人的风险,而深层次上的则是滥用转投资所形成的各种复杂的不良关系,从而损害他方权益。收益从来与风险共存, 我国《公司法》应取消对转投资对象和数额的限制。对所谓资本虚增可通过资本信息登记公示制度来规制。
