public versus private investment in human capital endogenous growth and income inequality in this paper we present an overlapping generations model with heterogeneous agents in which human capital investment through formal schooling is the engine of growth we use simple functional forms for preferences technologies and income distribution to highlight the distinction between economies with public education and those with private education we find that income inequality declines more quickly under public education on the other hand private education yields greater per capita incomes unless the initial income inequality is sufficiently high we also find that societies will choose public education if a majority of agents have incomes below average

competition between private and public schools vouchers and peer group effects a theoretical and computational model with tax financed tuition free public schools and competitive tuition financed private schools is developed students differ by ability and income achievement depends on own ability and on peers abilities equilibrium has a strict hierarchy of school qualities and two dimensional student sorting with stratification by ability and income in private schools high ability low income students receive tuition discounts while low ability high income students pay tuition premia tuition vouchers increase the relative size of the private sector and the extent of student sorting and benefit high ability students relative to low ability students

revenue decentralization and inflation a re evaluation abstract a problematic feature of the existing empirical literature on the relationship between revenue decentralization rd and inflation is the use of inaccurate measures for rd using a newly constructed measure for rd that accounts for over time changes in sub national tax autonomy this paper finds that rd leads to lower inflation

revenue decentralization and income distribution abstract due to varying local revenue collection capacities and interest group activities revenue decentralization rd may lead to increased inequality this paper provides empirical evidence however that if coupled with good governance rd could improve income distribution

centralization fiscal federalism and private school attendance a cge model is used to analyze the impact of public school financing on private school attendance the common perception that public school finance centralization will necessarily lead to greater private school attendance is not correct in such a model even when that centralization involves an extreme equalization as in california furthermore if centralization is less dramatic as in most states declines in private school attendance are even more pronounced this weakens the speculation that low exit rates to private schools in centralizing states imply that general public school quality does not drop as a result of such centralization

further evidence on revenue decentralization and inflation abstract results from a panel regression study of 19 oecd member countries suggest that when the measure of revenue decentralization is limited to the revenues over which sub national governments have full autonomy its impact on inflation is not statistically significant

evaluating china s natural gas supply security based on ecological network analysis abstract growing role of natural gas as an effective policy choice has kindled the discussions surrounding the security of its supplies in the policy circles of the chinese government this study tries to evaluate china s natural gas supply security and employs a system oriented modelling approach namely ecological network analysis ena to integrate all the critical compartments of china s natural gas supply system several ena indicators are constructed which disclose that domestic natural gas production contributes significantly to china s natural gas supply system in comparison with all the external natural gas suppliers in addition the variations in a system stability indicator suggest that diversification of external natural gas suppliers has a positive influence on china s natural gas supply security furthermore the results revealed that china s natural gas supply security policy is orchestrated on following features 1 to increase the investment in the upstream natural gas production sector to boost its domestic production in order to reduce its import requirements and 2 to diversify the external natural gas supplies by sources and routes to reduce the level of the economic and supply disruption related risks

fiscal decentralization central bank independence and inflation abstract we develop earlier cross sectional studies of inflation rates by adding the degree of tax centralization as another explanatory variable this makes central bank independence perform appreciably better as an explanatory variable also we find that centralized countries have higher inflation

cross country differences in intergenerational earnings mobility international studies of the extent to which economic status is passed from one generation to the next are important for at least two reasons first each study of a particular country characterizes an important feature of that country s income inequality second comparisons of intergenerational mobility across countries may yield valuable clues about how income status is transmitted across generations and why the strength of that intergenerational transmission varies across countries the e rst section of this paper explains a benchmark measure of intergenerational mobility commonly used in u s studies the second section summarizes comparable empirical e ndings that have accumulated so far for countries other than the united states the third section sketches a theoretical framework for interpreting cross country differences in intergenerational mobility

intergenerational income mobility in the united states social scientists and policy analysts have long expressed concern about the extent of intergenerational income mobility in the united states but remarkably little empirical evidence is available the few existing estimates of the intergenerational correlation in income have been biased downward by measurement error unrepresentative samples or both new estimates based on intergenerational data from the panel study of income dynamics imply that the intergenerational correlation in long run income is at least 0 4 indicating dramatically less mobility than suggested by earlier research copyright 1992 by american economic association

fiscal decentralization central bank independence and inflation a panel investigation we reinvestigate the relationship between revenue decentralization rd central bank independence cbi and inflation by modifying the paper by eco 72 2001 95 we show that in contrast to the earlier findings rd has a negative impact on inflation if accompanied by both cbi and local accountability in low inflation countries however rd has a negative impact on inflation even without these additional factors though cbi accentuates this effect

on the role of job assignment in a comparison of education systems abstract this paper re examines how differences in systems for financing education influence gdp by highlighting a neglected function of education policy it affects the magnitude of gains from job assignment when more productive jobs demand more skill privately financed education can increase productivity gains from matching between jobs and skill by increasing the availability of highly educated people this differs from the standard argument that publicly financed education increases the total amount of human capital by equalizing educational opportunities it is shown that if job opportunities have large variations in productivity education policy may face a serious efficiency equity trade off

ability tracking school competition and the distribution of educational benefits abstract to study the effects of ability grouping on school competition we develop a theoretical and computational model of tracking in public and private schools we examine tracking s consequences for the allocation of students of differing abilities and income within and between public and private schools private schools tend to attract the most able and wealthiest students and rarely track in equilibrium public sector schools can maximize attendance by tracking students public schools retain a greater proportion of higher ability students by tracking but lose more wealthy lower ability students to the private sector consequently socioeconomic status is a predictor of track assignment in public schools for the entire population public sector tracking has small aggregate effects on achievement and welfare but results in significant redistribution from lower to higher ability students

mobility targeting and private school vouchers simulations are derived from a three district model of low middle and highincome school districts calibrated to new york data with housing stocks that vary within and across districts in this model it is demonstrated that school district targeted vouchers are similar in their impact to nontargeted vouchers but vastly different from vouchers targeted to low income households furthermore strong migration effects are shown to significantly improve the likely equity consequences of voucher programs jel 122 128 h73 persistent frustration with the perceived low quality of public education exacerbated by concerns over the inherently unequal levels of public school quality across school districts has caused policy makers courts and researchers to investigate modifications and alternatives to the current public school system one idea that has received increasing academic and public attention is that of private school vouchers with proponents arguing that the competitive pressures of voucher programs would cause improvements in the efficiency of the publicschool system while at the same time addressing equity concerns if vouchers can be targeted to low income households or low income school districts but aside from a few limited experiments in some u s cities our experience with vouchers in the united states remains virtually nonexistent this limits the amount of information researchers can derive from standard empirical analysis in that it forces them to rely on only current nonvoucher induced differences in competition despite important suggestive results such work may not anticipate all the impacts from a large scale policy such as the voucher policies currently under discussion at the same time theoretical models of school finance are also limited in that they often either focus on only one particular aspect of the general equilibrium school finance problem or they are too rich and complex to yield crisp predictions

the desegregating effect of school tracking this paper makes the following point detracking schools that is preventing them from allocating students to classes according to their ability may lead to an increase in income residential segregation it does so in a simple model where households care about the school peer group of their children if ability and income are positively correlated tracking implies that some high income households face the choice of either living in the areas where most of the other high income households live and having their child assigned to the low track or instead living in lower income neighbourhoods where their child would be in the high track under mild conditions tracking leads to an equilibrium with partial income desegregation where perfect income segregation would be the only stable outcome without tracking

tax and education policy in a heterogeneous agent economy what levels of redistribution maximize growth and efficiency this paper studies the effects of progressive income taxes and education finance in a dynamic heterogeneous agent economy such redistributive policies entail distortions to labor supply and savings but also serve as partial substitutes for missing credit and insurance markets the resulting tradeoffs for growth and efficiency are explored both theoretically and quantitatively in a model that yields complete analytical solutions progressive education finance always leads to higher income growth than taxes and transfers but at the cost of lower insurance overall efficiency is assessed using a new measure that properly reflects aggregate resources and idiosyncratic risks but unlike a standard social welfare function does not reward equality per se simulations using empirical parameter estimates show that the efficiency costs and benefits of redistribution are generally of the same order of magnitude resulting in plausible values for the optimal rates aggregate income and aggregate welfare provide only crude lower and upper bounds around the true efficiency tradeoff

tracking can be more equitable than mixing parents and policy makers often wonder whether and how the choice of a tracked or mixed educational system affects the equality of opportunity i answer this question by analyzing the influence of peers on future educational results i define an equal opportunity policy as one that maximizes the average lifetime income of the worst off type of individuals in society i e students from disadvantaged backgrounds i find that tracking maximizes average lifetime income if the opportunity cost of college attendance is sufficiently high

fiscal decentralization fiscal rules and fiscal discipline fiscal decentralization fd and fiscal rules fr are institutional mechanisms that are implemented by varying degrees in increasing number of countries this paper investigates empirically the effect of fr on the effectiveness of fd in achieving fiscal discipline panel evidence strongly supports that balanced budget and expenditure rules help fd to achieve this goal while debt rule has a direct disciplinary effect

does the diversity of human capital increase gdp a comparison of education systems abstract this paper examines how different education systems affect gdp by influencing the diversity of human capital we construct an overlapping generation model in which agents are heterogeneous in income and innate ability and the final goods are produced with differentiated intermediate goods it is shown that under a realistic condition the diversity of human capital induced by income inequality always lowers the gdp of the next period while the diversity of human capital induced by heterogeneous ability can increase gdp if the produced intermediate goods are sufficiently substitutable and firms have a large span of control hence as public education equalizes education resources across households it mitigates the negative effect of income inequality on gdp while the effects of ability tracking crucially depend on the production structure of the economy

trade and divergence in education systems this article presents a theory on the endogenous choice of education policy and the two way causal relationship between trade and education systems a country s education system determines its talent distribution and comparative advantage the possibility of trade by raising the returns to the sector of comparative advantage in turn induces countries to further differentiate their education systems and reinforces the initial pattern of comparative advantage specifically the nash equilibrium choice of education systems by two countries interacting strategically are necessarily more divergent than their autarky choices and yet less than what is socially optimal for the world

heterogeneity stratification and growth macroeconomic implications of community structure and school finance this paper examines how socioeconomic stratification and alternative systems of education finance affect inequality and growth agents interact through local public goods or externalities school funding neighborhood effects and economywide linkages complementary skills knowledge spillovers sorting families into homogeneous communities often minimizes the costs of existing heterogeneity but mixing reduces heterogeneity faster integration therefore tends to slow down growth in the short run yet raise it in the long run a move to state funding of education presents society with a similar intertemporal trade off local and global complementarities play major roles in determining the efficient social and educational structures copyright 1996 by american economic association

the overseas acquisitions and equity oil shares of chinese national oil companies a threat to the west but a boost to china s energy security abstract this paper argues that both china and the western countries need to de politicize china s global quest for energy security the western politicians need to recognize that their rhetoric in relation to china s efforts to secure energy supplies overseas has done nothing but intensify china s fear that they might seek to deny china s access to the oil it needs for the development china needs to reconsider its stance of distrusting global oil markets and to recognize that the reliance on aggressive acquisitions of overseas oil fields and equity oil production has been of little help in strengthening its energy security given that china s energy security depends increasingly and deeply on the stability of global oil markets and reliable and growing oil supplies to the market china shares with other major oil importing countries profound common interests in maintaining and strengthening the stability of global oil markets and reducing the chance of potential disruptions to oil supply and the resulting damaging oil price shocks
