the chinese economy past present and future since initiating reforms in 1978 china has experienced an unprecedented rate of economic growth and development to become the second largest economy in the world after the united states yet there is so much that we do not know about the internal workings and operations of the chinese economy in part because the available english language literature is but a fraction of the scholarly work on china english speaking scholars business people analysts and policy makers are typically excluded from chinese language scholarship analysis and commentary or are often limited to executive summary type articles from business literature outlets we hope to fill at least part of the gap in the story of china past present and future with nine up to date surveys on some of the critical issues facing china which have been written by leaders in the relevant fields of scholarship

marshall s scale economies using panel data this paper estimates plant level production functions for machinery and high tech industries that allow for scale externalities from other plants in the same industry locally and from the scale or diversity of local economic activity outside the own industry the paper finds that the count of other own industry plants representing a count of local information spillover sources has strong productivity effects in high tech but not machinery industries single plant firms both benefit more from and generate greater external benefits than corporate plants given their greater reliance on external environments on dynamic externalities high tech single plant firms benefit also from the scale of past own industry activity i find little evidence of economies from the diversity or scale of local economic activity outside the own industry

a large scale mapping of territorial development dynamics in latin america summary this paper summarizes a study of changes in per capita income monetary poverty and income distribution in 9 045 subnational administrative units of nine latin american countries between the mid 1990s and mid 2000s the results largely support spatial convergence of mean household incomes although the estimates indicate it has been slow territorial inequality is found to be persistent and reduces the pro poor effect of local income growth although national context specific the estimates also indicate that territorial development dynamics are influenced by the structural features of the territories in view of the evidence territorial development policies in latin america seem well warranted

spatial patterns of private sector and public sector non agricultural jobs in rural northeast thailand lohmann c and liefner i spatial patterns of private sector and public sector non agricultural jobs in rural northeast thailand regional studies published evidence from developing countries shows that in rural areas participation in non agricultural wage employment rises with proximity to urban centres while earnings do not this paper explores the reasons for this phenomenon analysing the job characteristics of rural workers in detail the data set consists of 900 jobs the results show that public jobs are over represented in rural remote regions driving up the mean wage of this type of region when considering private sector employment only spatial wage and income differentials do exist showing that workers in remote areas are economically more disadvantaged than workers in peri urban areas

prudence with respect to ambiguity under expected utility prudence is equivalent to a positive third derivative of utility and plays a crucial role in precautionary saving behaviour eeckhoudt and schlesinger 2006 proposed behavioural definitions of prudence and of higher order risk preferences the present paper proposes a similar definition for prudence with respect to ambiguity i e situations in which objective probabilities are not available implications for several ambiguity models are derived ambiguity prudence is implied by hansen and sargent s 2001 multiplier preferences empirically correlates with financial behaviour and plays a key role in prevention behaviour this article is protected by copyright all rights reserved

are chinese cities too small this paper models and estimates net urban agglomeration economies for cities economic models of cities postulate an inverted u shape of real income per worker against city employment where the inverted u shifts with industrial composition across the urban hierarchy of cities this relationship has never been estimated in part because of data requirements china has the necessary data and context we find that urban agglomeration benefits are high real incomes per worker rise sharply with increases in city size from a low level they level out nearer the peak and then decline very slowly past the peak we find that a large fraction of cities in china are undersized due to nationally imposed strong migration restrictions resulting in large income losses

the impact of tax deductible saving on dynamic efficiency abstract the simulations reported in this paper suggest that permitting unlimited tax deductivility for saving under a progressive personal income tax could have a more favourable impact on total personal saving and capital accumulation than even a switch to a progressive consumption tax

labor migration and earnings differences the case of rural china this article presents empirical evidence supporting the hypothesis that the decision of chinese rural people to migrate is affected by noneconomic forces using the 1820 rural household survey from sichuan province migration behavior and earnings are analyzed logistic probability models show that the decision to migrate is driven largely by the availability of rural non farm employment opportunities however if jobs are available in the province even at lower wages rural people will choose to stay rather than to migrate the major deterrent to migration is the lack of safety during transportation and in destination cities as well as forced separation from families moreover rural migrants are denied the legal right to reside permanently in cities furthermore findings reveal that although labor productivity in migrant activities is higher than it is in local non farm sectors the economic cost of migration in china is so high as to significantly limit reallocation one implication of this study is that without artificial barriers to labor migration the number of migratory workers would be higher since the important objective of the chinese government is to control rural to urban migration it is likely that restrictive migration policies will continue however putting aside the issue of social justice the economic efficiency loss under the chinese system should not be ignored

urban biased policies and rising income inequality in china since the start of economic reforms in 1978 china has experienced the largest increase in income inequality of all countries for which comparable data are available according to the world bank 1997 china s gini coefficient increased from 28 2 in 1981 to 38 8 in 1995 based on official survey data another study that used internationally standard definitions for incomes estimated china s gini ratio at 38 2 in 1988 and 45 2 in 1995 a level that already surpassed many developing economies in asia azizur khan and carl riskin 1998 are these income inequality changes the consequence of institutional reforms that replaced egalitarian rewards with work incentives employment contracts and labor mobility this paper uses household survey data collected by china s state statistical bureau ssb to investigate the sources and causes of this rising inequality by analyzing gini ratios and generalized entropy measures i decompose the overall inequality into three sectoral components i inequality within rural areas ii inequality within urban areas and iii sectoral disparity the data indicate that increases in rural urban income differentials have been the driving factor behind the rising overall inequality in china i argue that urbanbiased policies and institutions including labor mobility restrictions welfare systems and financial policies of inflation subsidies and investment credits to the urban sector are responsible for the long term rural urban divide and the recent increases in disparity

productivity gains from geographic concentration of human capital evidence from the cities abstract based on recent theoretical developments the argument is made that the average level of human capital is a local public good cities with higher average levels of human capital should therefore have higher wages and higher land rents after conditioning on the characteristics of individual workers and dwellings this prediction is supported by data for standard metropolitan statistical areas smsas in the united states where the smsa average levels of formal education and work experience are used as proxies for the average level of human capital the alternative explanations of omitted smsa variables and self selection are evaluated an estimate of the effect of an additional year of average education on total factor productivity is computed

china s uneven progress against poverty while the incidence of extreme poverty in china fell dramatically over 1980 2001 progress was uneven over time and across provinces rural areas accounted for the bulk of the gains to the poor though migration to urban areas helped the pattern of growth mattered rural economic growth was far more important to national poverty reduction than urban economic growth agriculture played a far more important role than the secondary or tertiary sources of gross domestic product gdp rising inequality within the rural sector greatly slowed poverty reduction provinces starting with relatively high inequality saw slower progress against poverty due both to lower growth and a lower growth elasticity of poverty reduction taxation of farmers and inflation hurt the poor external trade had little short term impact

people places and earnings differentials in scotland abstractpeople places and earnings differentials in scotland regional studies this paper investigates the contribution of people and place effects to earnings differentials in scotland using individual and regional data the main sources of differentials are attributed to workers characteristics people effects particularly academic and vocational qualifications followed by occupational and industrial affiliations on the other hand differences in the attributes of local area labour markets place effects explain only a small part of individual earnings differentials the most relevant spatial attribute is local area human capital the findings suggest that people based policies are likely to be more effective at improving workers earnings prospects than place based policies

frictional labour mobility we build a dynamic model of migration where in addition to standard relocation costs workers face spatial frictions that decrease their ability to compete for distant job opportunities we estimate the model on a matched employer employee panel dataset describing labour market transitions within and between the 100 largest french cities our identification strategy is based on the premise that frictions affect the frequency of job transitions while mobility costs impact the distribution of accepted wages we find that 1 controlling for spatial frictions reduces mobility cost estimates by one order of magnitude 2 the urban wage premium is driven by better opportunities for local job to job transitions in larger cities 3 migration reduces lifetime inequalities by providing insurance against unsatisfactory initial location draws 4 labour mobility policies based on relocation subsidies are inefficient unlike switching from nationwide to local minimum wages

rural urban disparity and sectoral labour allocation in china this study examines china s rural urban segmentation and its causes in the context of economic reforms household survey and aggregate data indicate a v shaped process in which rural urban consumption and income differentials decreased between 1978 and 1985 but then have continually increased to historically high levels this sectoral division is consistent with production function estimates based on provincial data that reveal higher labour productivity in urban state owned industries than in rural industries and agriculture to explain the v shaped change we argue that the precedent of successful rural reforms raised farmers relative earnings but the remaining obstacles to an efficient sectoral allocation of labour have prevented china from eliminating dualism recent financial policies consisting of urban price subsidies and increased investment credits have also had influential distribution effects that are biased against the rural sector

migration externalities in chinese cities we analyse the impact of internal migration in china on natives labour market outcomes we find evidence of a large positive correlation of the city share of migrants with natives wages using different sets of control variables and instruments suggests that the effect is causal the large total migrant impact 10 when one moves from the first to the third quartile of the migrant variable distribution arises from gains due to complementarity with natives in the production function 6 4 and from gains due to agglomeration economies 3 3 finally we find some evidence of a stronger effect for skilled natives than for unskilled as expected from theory overall our findings support large nominal wage gains that can be expected from further migration and urbanisation in china

urban wages and labor market agglomeration abstract using the 5 public use micro sample of the 1990 u s census we find that observationally equivalent workers in the manufacturing sector earn higher wages when they are in urban labor markets that have a larger share of national or metropolitan employment in their same occupation and industry groups quantitatively the effect is large with an elasticity measured at the means of between 1 2 and 3 6 for these effects we interpret the willingness of firms to pay more for equivalent workers in dense markets as evidence of an agglomeration economy in urban labor

spatial aspects of chinese development issues outcomes and policies 1949 79 despite wide initial spatial inequalities and a respectable rate of national economic growth since 1949 available evidence suggests that certain key spatial inequalities in china have narrowed progress has been uneven however and there is no simple correlation to be found between the pursuit of maoist regional policies and the narrowing of spatial inequalities that actually occurred this points to the need to qualify the conclusion of many western scholars that maoist policies actually succeeded in achieving rapid sustainable growth while narrowing most differentials including spatial differentials

tax deferred savings plans and interest deductibility programs that defer taxes on savings e g rrsps or 401 k s are supposed to move income tax systems closer to the more efficient consumption tax whether or not rrsps move income tax systems away from or closer to a consumption tax depends on whether or not interest on debts incurred to make rrsp contributions is deductible for income tax purposes if people optimize as assumed in simple life cycle models then it may be that governments can convert a non linear income tax system to a proportional consumption tax system i argue this is plausible for some canadian households jel classification h21 h24 plans d epargne pour differer les impots et deductibilite des charges d interet les gouvernements ont mis en place des regimes d impots sur le revenu des personnes mais la plupart des gouvernements prennent des mesures pour attenuer les distorsions causees par la composante taxe sur l interet dans l impot sur le revenu un antidote populaire est le plan d epargne pour differer les impots pedi e g les reers ou 401 k s on pense que en reportant les impots sur les epargnes et les revenus d interet sur les epargnes de tels plans vont deplacer le regime fiscal d impot sur le revenu vers un regime plus efficient d impot sur la consommation l auteur suggere que l impact des pedi sur ce deplacement depend de la deductibilite de l interet sur la dette encourue pour faire les contributions aux fins de l impot sur le revenu si les gens optimisent comme on le pretend dans les modeles simples de cycles de vie alors il se peut que les gouvernements puissent convertir un systeme non lineaire d impot sur le revenu en un regime d impot proportionnel sur la consommation en permettant des pedi illimites et en prohibant la deductibilite des charges d interet

how do contribution limits affect contributions to tax preferred savings accounts abstract contributions to tax preferred savings accounts are typically constrained by a contribution limit these limits influence contributions not only for taxpayers currently constrained by the limit but also for those contributing less than the limit i develop a simple life cycle model in which taxpayers exhibit use it or lose it contribution behavior this connects current contributions to future contribution limits and implies that an increase in contribution limits can decrease contributions empirical evidence from microdata provides support for the model using variation from canadian limit reforms i find that larger future contribution room is associated with smaller contributions

some microeconometric evidence concerning the effect of the canada pension plan on personal saving growing criticism of canada s retirement income system during the past few years has resulted in renewed pressure on both federal and provincial governments to expand public pension programmes especially the canada pension plan cpp once again this prospect has aroused fears that an unfunded expansion of the public pension system could have a seriously adverse effect on personal saving the adverse effect on personal saving it is argued could in turn lower investment and thereby reduce even further what is already by postwar standards an extremely sluggish rate of productivity growth for the canadian economy however the basis for fearing that public pensions may reduce household saving is somewhat questionable since the wealth replacement effect of public pensions on saving may be offset by an induced retirement effect and perhaps by inter generational transfers in the form of bequests the theory at least is inconclusive in this regard 1 surprisingly enough unlike in the united states where the theoretical indeterminacy concerning the overall impact of public pensions on saving has spawned a multitude of empirical studies the subject has been largely ignored by econometricians in canada but sparse though the empirical evidence may be it does not support the seemingly popular contention that public pensions reduce personal saving in the only published empirical study to date boyle and murray 1979 conclude from their analysis of time series data that canada s public pension plans have had no visible effect on household savings behaviour this paper presents some cross sectional evidence on the response of personal saving to public pensions which appears to conflict with the boyle and murray findings it is organized as follows section i describes the methodology and the data base used the empirical results are analysed in section ii some conclusions follow in section iii

the impact of migration on rural poverty and inequality a case study in china large numbers of agricultural labor moved from the countryside to cities after the economic reforms in china migration and remittances play an important role in transforming the structure of rural household income this article examines the impact of rural to urban migration on rural poverty and inequality in a mountainous area of hubei province using the data of a 2002 household survey since migration income is a potential substitute for farm income we present counterfactual scenarios of what rural income poverty and inequality would have been in the absence of migration our results show that by providing alternatives to households with lower marginal labor productivity in agriculture migration leads to an increase in rural income in contrast to many studies that suggest that the increasing share of nonfarm income in total income widens inequality this article offers support for the hypothesis that migration tends to have egalitarian effects on rural income for three reasons 1 migration is rational self selection farmers with higher expected return in agricultural activities and or in local nonfarm activities choose to remain in the countryside while those with higher expected return in urban nonfarm sectors migrate 2 households facing binding constraints of land supply are more likely to migrate 3 poorer households benefit disproportionately from migration

designing a non distortionary personal tax system for canada abstract this paper discusses the design of a graduated personal tax system that does not distort the path of an individual s lifetime consumption it is shown that such a tax system requires the existence of both tax deductible and non tax deductible saving it is also argued that the mechanisms are already in place that would permit the transformation of canada s existing personal tax system into one similar to those proposed by blueprints and the meade committee

productivity and city size a critique of the evidence a critique of two leading articles in the productivity and city size literature results in revised estimates of the productivity advantages of large cities in particular extant estimates of the elasticity of productivity with city size are revised downward by over 100 percent for the manufacturing sector and about 25 percent for the entire urban economy after revision productivity advantages of larger cities are found to be much larger for the nonmanufacturing sector than for the manufacturing sector hence revitalization policies for large cities should be focused on nonmanufacturing sectors

the role of registered retirement savings plans in a life cycle model in this paper a distinction is made between two types of personal saving one of which is tax deductible and another which is not and the role of each is examined within the framework of a life cycle model more precisely the model shows how tax deductible rrsp saving enables the individual to do his own lifetime income averaging for tax purposes in order to generate the lifetime profile of taxable income which minimizes the discounted value of tax payments the use of rrsps for this purpose however does not usually result in income averaging in the conventional sense since it is not necessarily optimal for a person to equalize taxable income over each period of his lifetime by contrast non tax deductible saving permits the individual to choose his optimal lifetime consumption path and bequests le ro le des regimes enregistres d epargne retraite dans un modele d optimisation sur tout le cycle de vie dans ce m6moire l auteur distingue deux types d 6pargne personnelle l une d6ductible aux fins de l impot sur le revenu et l autre non le role de chacune est analyse dans le contexte d un modele d optimisation sur tout le cycle de vie plus pr6cis6ment le modele montre comment l 6pargne via les r6gimes enregistr6s d 6pargne retraite permet a l individu d 6taler son revenu total dans le temps aux fins d imp6t afin de construire un profil de revenu imposable qui minimise la valeur pr6sente des impots pay6s l utilisation des r6gimes enregistr6s d 6pargne retraite h cette fin n engendre pas necessairement un 6talement conventionnel du revenu puisqu il se peut fort bien qu il ne soit pas optimal pour l individu d 6galiser son revenu imposable pour chaque p6riode de sa vie d autre part l 6pargne qui n est pas d6ductible aux fins d impot sur le revenu permet h l individu de choisir le sentier optimal de consommation et de legs sur tout le cycle de vie

unequal migration and urbanisation gains in china abstract we assess the role of internal migration and urbanisation in china on the nominal earnings of three groups of workers rural migrants low skilled natives and high skilled natives we estimate the impact of many city and city industry characteristics that shape agglomeration economies as well as migrant and human capital externalities and substitution effects we also account for spatial sorting and reverse causality location matters for individual earnings but urban gains are unequally distributed high skilled natives enjoy large gains from agglomeration and migrants at the city level both conclusions also hold to a lesser extent for low skilled natives who are only marginally negatively affected by migrants within their industry by contrast rural migrants slightly lose from migrants within their industry while otherwise gaining from migration and agglomeration although less than natives the different returns from migration and urbanisation are responsible for a large share of wage disparities in china

spatial wage disparities sorting matters spatial wage disparities can result from spatial differences in the skill composition of the workforce in non human endowments and in local interactions to distinguish between these explanations we estimate a model of wage determination across local labour markets using a very large panel of french workers we control for worker characteristics worker fixed effects industry fixed effects and the characteristics of the local labour market our findings suggest that individual skills account for a large fraction of existing spatial wage disparities with strong evidence of spatial sorting by skills interaction effects are mostly driven by the local density of employment not controlling for worker heterogeneity leads to very biased estimates of interaction effects endowments only appear to play a small role

wages rents and the quality of life this study focuses on the role of wages and rents in allocating workers to locations with various quantities of amenities the theory demonstrates that if the amenity is also productive then the sign of the wage gradient is unclear while the rent gradient is positive the theory is extended to include the housing market and nontraded goods these extensions require little modification of the conclusion the empirical work on wages shows that the regional wage differences can be explained largely by these local attributes with the use of site price data implicit prices are estimated and quality of life rankings for the cities are computed

technological specialization and variety in urban invention o huallachain b and lee d s technological specialization and variety in urban invention regional studies urban economic theory distinguishes between knowledge spillovers that occur within specializations and those that cross technologies empirical analysis has sought to gauge their relative strength but the results are inconclusive metropolitan specialization and variety at different aggregation levels of a us patent classification system are assessed using theil s relative entropy index the results show that specialization and variety are not competing features of urban technological structure cities can have both the invention rate positively associates with specialization in diverse technologies the cross fertilization of ideas among skilled professionals with different expertise and the interaction between specialists of narrow fields of knowledge are both important in technological advance the most inventive cities have deep specializations in different technologies the results also sho

french unemployment a transatlantic perspective french unemployment why france and the usa are alike the paper compares the french and us labour markets it shows that differences in unemployment rates are especially acute for young and old workers but appear to be negligible for middle aged workers all french workers however experience job flows that are quite distinct from their american counterparts as they are exposed to long spells of infrequent unemployment which is the opposite to the us case critical differences across ages and skills regarding the patterns of exit from and entry into employment are also displayed the paper dispels the view that these differences originate from the behaviour of the unemployed or the set of institutions that guide their decisions and that this is new to the french labour market daniel cohen arnaud lefranc and gilles saint paul

cities and the growth of wages among young workers evidence from the nlsy abstract human capital based theories of cities suggest that large economically diverse urban agglomerations increase worker productivity by increasing the rate at which individuals acquire skills one largely unexplored implication of this theory is that workers in big cities should see faster growth in their earnings over time than comparable workers in smaller markets this paper examines this implication using data on a sample of young male workers drawn from the national longitudinal survey of youth 1979 cohort the results suggest that earnings growth does tend to be faster in large economically diverse local labor markets defined as counties and metropolitan areas than in smaller more specialized markets yet when examined in greater detail i also find that this association tends to be the product of faster wage growth due to job changes rather than faster wage growth experienced while on a particular job this result is consistent with the idea that cities enhance worker productivity through a job search and matching process and thus that an important aspect of learning in cities may involve individuals learning about what they do well

mobility and the return to education testing a roy model with multiple markets self selected migration presents one potential explanation for why observed returns to a college education in local labor markets vary widely even though u s workers are highly mobile to assess the impact of self selection on estimated returns this paper first develops a roy model of mobility and earnings where workers choose in which of the 50 states plus the district of columbia to live and work available estimation methods are either infeasible for a selection model with so many alternatives or place potentially severe restrictions on earnings and the selection process this paper develops an alternative econometric methodology that combines lee s 1983 parametric maximum order statistic approach to reduce the dimensionality of the error terms with more recent work on semiparametric estimation of selection models e g ahn and powell 1993 the resulting semiparametric correction is easy to implement and can be adapted to a variety of other polychotomous choice problems the empirical work which uses 1990 u s census data confirms the role of comparative advantage in mobility decisions the results suggest that self selection of higher educated individuals to states with higher returns to education generally leads to upward biases in ols estimates of the returns to education in state specific labor markets while the estimated returns to a college education are significantly biased correcting for the bias does not narrow the range of returns across states consistent with the finding that the corrected return to a college education differs across the u s the relative state to state migration flows of college versus high school educated individuals respond strongly to differences in the return to education and amenities across states

understanding the city size wage gap in 2000 wages of full time full year workers were more than 30 percent higher in metropolitan areas of over 1 5 million people than rural areas the monotonic relationship between wages and city size is robust to controls for age schooling and labor market experience in this paper we decompose the city size wage gap into various components we propose an on the job search model that incorporates latent ability search frictions firm worker match quality human capital accumulation and endogenous migration between large medium and small cities counterfactual simulations of the model indicate that variation in returns to experience and differences in wage intercepts across location type are the most important mechanisms contributing to the overall city size wage premium steeper returns to experience in larger cities is more important for college graduates while differences in wage intercepts is more important for high school graduates sorting on unobserved ability within education group and differences in labor market search frictions and distributions of firm worker match quality contribute little or slightly negatively to observed city size wage premia in both samples

income inequality in the people s republic of china trends determinants and proposed remedies the issue of income inequality in the people s republic of china prc has attracted world wide attention leading to a sizable literature this paper attempts to provide a nonexhaustive literature review of the prc s inequality trends and determinants and suggested government interventions it discusses profiles of income inequality along three dimensions interhousehold disparity regional divides and urban rural gaps this is followed by an exploration of the driving forces behind rising inequality including the notorious hukou system policy biases location or geographic factors globalization and education finally the paper summarizes and proposes government interventions for containing or reducing income inequality in the prc important areas for future research are also suggested in the final section of the paper

does unmeasured ability explain inter industry wage differentials this paper provides empirical assessments of the two leading explanations of measured inter industry wage differentials 1 true wage differentials exist across industries and 2 the measured differentials simply reflect unmeasured differences in workers productive abilities first we summarize the existing evidence on the unmeasured ability explanation second we construct a simple model which shows that if matching is important then endogenous job change decisions can create important self selection biases even in first differenced estimates of industry wage differentials third we analyze a sample that approximates the experiment of exogenous job loss we find that i the wage change experienced by a typical industry switcher closely resembles the difference in the relevant industry differentials estimated in a cross section and ii pre displacement industry affiliation plays an important role in post displacement wage determination

marshall s scale economies and jacobs externality in korea the role of age size and the legal form of organisation of establishments this paper revisits the concept of agglomeration economies by estimating the effects of localisation urbanisation and local competition on labour productivity using establish ment level data in korean manufacturing industries it is found that when an establish ment locates in a more localised specialised more urbanised diversified and more competitive area its workers become more productive due to external benefits from agglomeration issues of self selection bias and omitted variable bias are addressed by instrumenting the variables measuring localisation economies and controlling for the fixed effects of establishments location and industries year however the external effects from the spatial proximity of other establishments vary across the categories of industry type age size and legal form of organisation of establishments establishments in traditional heavy manufacturing industries receive more external benefits in a less diversified area while those in transport equipment manufacturing industries enjoy the largest benefits from localisation externalities exist for establishments aged between 2 and 7 years having at least 10 workers being corporate and having multiplants or not being headquarters establishments in relatively young industries rely more on diver sified environments while establishments in relatively old industries receive greater external benefits in the same industry cluster this result supports the product life cycle location theory of duranton and puga

the reflection effect for higher order risk preferences higher order risk preferences are important determinants of economic behaviour we apply insights from behavioural economics we measure higher order risk preferences for pure gains and losses we find a reflection effect not only for second order risk preferences like kahneman and tversky 1979 but also for higher order risk preferences we find risk aversion prudence and intemperance for gains and much more risk loving preferences imprudence and temperance for losses these findings are at odds with a universal preference for combining good with bad or good with good which previous results suggest may underlie higher order risk preferences

the migration of technical workers using panel data on the danish population we estimated the revealed preferences of scientists and engineers for the places in which they choose to work our results indicate that these technical workers exhibit substantial sensitivity to differences in wages but that they have even stronger preferences for living close to family and friends the magnitude of these preferences moreover suggests that the greater geographic mobility of scientists and engineers relative to the population as a whole stems from more pronounced variation across regions in the wages that they can expect these results remain robust to estimation on a sample of individuals who must select new places of work for reasons unrelated to their preferences those who had been employed at establishments that discontinued operations

the treatment of registered retirement savings plans at maturity abstract in recent years we have witnessed a dramatic rise in the popularity of tax deductible registered retirement savings plans as an increasing number of canadians have taken advantage of the tax saving associated with these do it yourself pension schemes as a quid pro quo the income tax act restricts the manner in which the proceeds of an rrsp can be used to generate a retirement income this note examines the annuity aspect of rrsps and how the imposition of such a constraint on withdrawals affects the optimal control solution to the individual planholder s utility maximization problem

what is different about urbanization in rich and poor countries cities in brazil china india and the united states abstract are the well known facts about urbanization in the united states also true for the developing world we compare american metropolitan areas with analogous geographic units in brazil china and india both gibrat s law and zipf s law seem to hold as well in brazil as in the u s but china and india look quite different in brazil and china the implications of the spatial equilibrium hypothesis the central organizing idea of urban economics are not rejected the india data however repeatedly rejects tests inspired by the spatial equilibrium assumption one hypothesis is that spatial equilibrium only emerges with economic development as markets replace social relationships and as human capital spreads more widely in all four countries there is strong evidence of agglomeration economies and human capital externalities the correlation between density and earnings is stronger in both china and india than in the u s strongest in china in india the gap between urban and rural wages is huge but the correlation between city size and earnings is more modest the cross sectional relationship between area level skills and both earnings and area level growth are also stronger in the developing world than in the u s the forces that drive urban success seem similar in the rich and poor world even if limited migration and difficult housing markets make it harder for a spatial equilibrium to develop

marriage and the city search frictions and sorting of singles this paper develops and tests a model where cities play an important role as marriage markets the idea is simple cities are dense areas where singles can meet more potential partners than in rural areas to enjoy those benefits they are willing to pay a premium in terms of higher housing prices once married the benefits from meeting more potential partners vanish and married couples move out of the city attractive singles benefit most from a dense market and are therefore more likely to move to the city those predictions are tested and confirmed with a unique danish data set

income inequalities in china evidence from household survey data on the basis of a household data set this paper compares household income inequality in urban and rural china decomposes inequality into intra and interprovincial components and analyzes the contribution of various income sources to total income equality the main findings of the paper are first that unlike in most developing economies income inequality in urban areas is lower than in rural areas second nationwide income inequality is due mostly to intraprovincial inequality third components of income associated with economic reforms are more unequally distributed than the rest

measuring multivariate risk preferences in the health domain we investigate univariate and multivariate risk preferences for health longevity and wealth we measure attitudes toward correlation and attitudes toward higher order dependence structures such as cross prudence and cross temperance making use of the risk apportionment technique proposed by eeckhoudt et al 2007 for multivariate gains we find correlation aversion and cross prudence in longevity and wealth for losses we observe correlation seeking and cross imprudence we do not find clear evidence for cross temperance our results indicate that longevity and wealth are considered to be substitutes for gains but not for losses second univariate higher order risk preferences are comparable for longevity and wealth although somewhat closer to linearity for wealth third we find evidence that attitudes toward dependence structures in the health domain are sign dependent

progressive income taxes and the substitution effect of rrsps within a progressive income tax system registered retirement saving plans rrsps generate a substitution effect that decreases saving the key point made here is that when an rrsp is introduced to a system that taxes capital income the rate of return on marginal saving within the rrsp is driven to equality with the rate of return on non rrsp saving since rrsp contributions redistribute taxable income across periods they also have the effect of increasing future marginal income tax rates which lowers the after tax return to saving this result stands in contrast to the conventional view from the public finance literature

spatial changes in labour market inequality abstract we study spatial changes in labour market inequality for us states and msas using census and american community survey data between 1980 and 2010 we report evidence of significant spatial variations in education employment shares and in the college wage premium for us states and msas and show that the pattern of shifts through time has resulted in increased spatial inequality because relative supply of college versus high school educated workers has risen faster at the spatial level in places with higher initial supply levels we also report a strong persistence and increased inequality of spatial relative demand bigger relative demand increases are observed in more technologically advanced states that have experienced faster increases in r d and computer usage and in states where union decline has been fastest finally we show the increased concentration of more educated workers into particular spatial locations and rising spatial wage inequality are important features of labour market polarization as they have resulted in faster employment growth in high skill occupations but also in a higher demand for low wage workers in low skill occupations overall our spatial analysis complements research findings from labour economics on wage inequality trends and from urban economics on agglomeration effects connected to education and technology

interprovincial disparities in china output and consumption 1952 1987 the flood of economic information from china in recent years has permitted reassessment of the chinese model of development and the extent to which china s own development experience has conformed to it the prevailing consensus of the 1970s concerning the substance of the model itself typically characterized in terms of the chinese leadership s objectives and priorities and its strategy for pursuing them has stood up quite well the same cannot be said about past appraisals of the extent to which china s economic reality has been reshaped to accord with the model s prescriptions one of the most widely remarked elements of the chinese model is the high priority assigned to regional objectives and more specifically to balance in the distribution of productive capacity and equity in the distribution of income and hence consumption during the maoist era i e prior to 1979 the central government pursued regional objectives through such measures as interregional transfers of investment resources effected via the planning system subsidization of health and education expenditures in poor regions and attempts to maintain a safety net of state relief effected largely via control of grain surpluses in short there is little doubt that prior to 1979 the chinese leadership placed an unusually high value on the spread of modern growth and the improvements in welfare associated with it and persistently acted to limit the emergence or widening of interregional disparities although china s post mao leaders have shown greater concern with efficiency and with the potential trade offs between efficiency and such goals as balance and equity their continuation of many redistributive policies indicates that they have not abandoned regional objectives but how successful has china been in achieving these objectives

the erroneous use of china s population and per capita data a structured review and critical test hundreds of studies in economics misinterpret china s subnational population and per capita data the most widely used population counts are of hukou registrations from each province prefecture county or city rather than of the people living in each place and generating local gross domestic product over 220 million people have left their place of registration while almost none had when reforms began creating time varying errors in estimates of per capita income of subnational units we survey empirical articles in blue ribbon journals in development journals and in regional and urban economics journals that use china s subnational data over 80 of articles use these data erroneously most commonly the wrong population or employment counts are used to measure the size of subnational units and per capita data are calculated with the wrong denominator for how variables are interpreted we provide examples of errors from each group of journals and a critical test of one highly cited study specifically we show that if hukou registrations are erroneously used to measure the local population following existing practice conclusions about driving forces for urban area expansion are reversed we give recommendations for more careful use of china s subnational population and per capita data

the impact of public pensions on personal retirement saving in canada some evidence from cross section data during recent years much attention has been focused on the question of whether or not public retirement income systems have an adverse effect on personal saving the concern has been expressed in a number of countries that if there is any reduction in saving it could result in a lower rate of capital accumulation and as a consequence slower productivity growth unfortunately the theoretical literature on the subject is inconclusive within the framework of a life cycle model where saving and retirement decisions are made jointly the overall effect of public pensions is ambiguous depending on the relative strengths of the wealth replacement effect and the induced retirement effect 9 10 the former effect reduces saving while the latter tends to increase it the issue is further complicated by the possibility that individuals might attempt to vitiate what the public pension system does through offsetting changes in private intergenerational transfers in the form of bequests 1 14 it would appear therefore that only empirical evidence can determine the extent to which public pensions affect personal saving whereas in the united states a great deal of research much of it with conflicting results has been devoted to shedding further light on this very important issue in canada the subject has been somewhat neglected what little evidence there is however lends little support to the popular view that public pension programs such as old age security oas and the canada pension plan cpp have had a negative effect on saving boyle and murray in their recent study conclude from time series regressions that canada s public pension plans have had no visible effect on household savings behaviour 2 467

a numerical simulation analysis of hukou labour mobility restrictions in china abstract we use numerical simulation methods to analyze the hukou system of permanent registration in china which many believe has supported growing relative inequality over the last 20 years by restraining labour migration both between the countryside and urban areas and between regions and cities our aim is to inject economic modelling into the debate on sources of inequality in china which thus far has been largely statistical we first use a model with homogeneous labour in which wage inequality across various geographical divides in china is supported solely by quantity based migration restrictions urban rural areas rich poor regions eastern central and western non coastal zones eastern and central western development zones eastern central western zones more disaggregated 6 regional classifications and an all 31 provincial classification we calibrate this model to base case data and when we remove migration restrictions all wage and most income inequality disappears results from this model structure points to a significant role for hukou restrictions in supporting inequality in china we then present a further model extension in which urban house price rises retard rural urban migration the impacts of removing hukou restrictions on migration are smaller but are still significant finally we modify the model to capture labour productivity differences across regions calibrating the modified model to estimates of both national and regional gini coefficients removal of migration barriers is again inequality improving but less so

multilevel approaches and the firm agglomeration ambiguity in economic growth studies empirical studies in spatial economics have shown that agglomeration economies may be a source of the uneven distribution of economic activities and economic growth across cities and regions both localization and urbanization economies are hypothesized to foster agglomeration and growth but recent meta analyses of this burgeoning body of empirical research show that the results are ambiguous recent overviews show that this ambiguity is fuelled by measurement issues and heterogeneity in terms of scale of time and space aggregation growth definitions and the functional form of the models applied alternatively in this paper we argue that ambiguity may be due to a lack of research on firm level performance in agglomerations this research is necessary because the theories that underlie agglomeration economies are microeconomic in nature hierarchical or multilevel modeling which allows micro levels and macro levels to be modeled simultaneously is becoming an increasingly common practice in the social sciences as illustrated by detailed dutch data on firm level productivity employment growth and firm survival we argue that these approaches are also suitable for reducing the ambiguity surrounding the agglomeration firm performance relationship and for addressing spatial sectoral and cross level heterogeneity
