democracy community trust the impact of elections in rural china this article systematically investigates the impact of elections in rural china on a basic element of the elite mass relationship beliefs of ordinary citizens that their leaders are trustworthy it analyzes data from two surveys of randomly sampled villagers in the same 57 villages in 1990 and 1996 merged with a set of separately collected data detailing features of elections in these villages during the same period of time the analyses take advantage of uneven progress in grassroots democratization and ask how variation in democratic electoral quality across villages is associated with variation in changed views about the probity or venality of local leaders results strongly suggest that formal institutions of electoral democracy matter designs that feature contestation and encourage voter participation do better at promoting beliefs that leaders are trustworthy at the same time results point to the importance of informal community institutions of lineage relationships

mutual empowerment of state and peasantry grassroots democracy in rural china abstract this paper aims to explore alternative pathways to democracy by studying the origins processes and impacts of a recent political development in china within the framework of an authoritarian state the gradual emergence of some genuine grassroots self government especially in rural areas the major argument is that the practice of self government in rural china was promoted by the state to regain the legitimacy and governability it had lost during the economic reforms it is a critical process in which the state and the peasantry are mutually empowering each other by linking peasant demands to state power through the mechanism of grassroots elections and self governing villager committees the chinese case shows that the empowerment of new social forces does not necessarily weaken the capacity of the state to govern society and therefore in the long run a peaceful and orderly democratic transition might be possible

a mismatch made in heaven a hedonic analysis of overeducation and undereducation in this paper a hedonic pairing process is modeled in which some workers may be overeducated or undereducated as an equilibrium outcome of a dynamic labor market undereducated workers are those whose abilities and training permit them to move into a job with higher qualifications whereas overeducated workers are highly qualified workers who select into lower skill entry level jobs that provide the training or signal necessary for promotion the empirical model shows that these pairing types cannot be directly identified in a cross section since all workers are exactly educated during a portion of their career however pairing types may be imputed by comparing predicted and observed qualifications of the worker and predicted and observed requirements of the firm using a rich cross section and a panel of british working age males to identify the pairing types we confirm the predicted career development patterns with regard to on the job training promotion and wages

measuring over education previous work on over education has assumed homogeneity of workers and jobs relaxing these assumptions we find that over educated workers have lower education credentials than matched graduates among the over educated graduates we distinguish between the apparently over educated workers who have similar unobserved skills as matched graduates and the genuinely over educated workers who have a much lower skill endowment over education is associated with a pay penalty of 5 11 for apparently over educated workers compared with matched graduates and of 22 26 for the genuinely over educated over education originates from the lack of skills of graduates this should be taken into consideration in the current debate on the future of higher education in the uk

educational mismatch and promotions to managerial positions a test of the career mobility theory abstractcareer mobility theory suggests that given a certain occupation schooling improves upward mobility in terms of promotion and wage growth we are the first to test the implications of this theory for over and undereducation by means of direct information about promotions to managerial positions using german administrative data entailing an employer reported and hence objective measure of educational requirements we show that overeducated workers are indeed more likely to be promoted and that this career mobility advantage is more pronounced in the early stages of their working lives by contrast undereducated workers are less likely to be promoted to managerial positions moreover in terms of wage growth while overeducated workers benefit more undereducated workers benefit less from promotions than their well matched educational peers altogether these findings strongly support the career mobility theory furthermore by differentiating between internal and external promotions we prov

mismatch in the spanish labor market overeducation the objective of this article is to explain the job match which is assessed by comparing attained education and job required education as reported by workers we frame our empirical work according to the occupational mobility theory using a cross section of workers from a representative survey of the spanish labor force we consider overeducated workers to be those who report that the level of education their jobs require is below the level of education they have attained our results indicate that overeducated workers have less experience decreased on thejob training and higher turnover than other comparable workers we also observe an improvement in the job match over age and mobility

racing to the bottom or to the top decentralization revenue pressures and governance reform in china summary china s decentralization has been praised for promoting inter jurisdictional competition that incentivizes local officials to promote economic development the downside of decentralization is that it enables these same local authorities to slow or block implementation of centrally mandated governance reforms especially when these may negatively affect local development goals we suggest that china s fiscal system and promotion system have created mismatched incentives that encourage cash strapped local authorities to disregard central governance reforms specifically we show that cities with weaker revenue bases were slower to implement new centrally mandated environmental transparency regulations additional evidence points to a bifurcation in development strategies in fiscally strong cities increased foreign investment leads to greater compliance in fiscally weak cities foreign investment is associated with decreased disclosure suggesting they aim to promote local development by becoming pollution havens similarly high levels of pollution induce fiscally strong cities to increase pollution disclosures while the opposite holds in fiscally weak cities these findings imply that mismatched decentralization policies can undermine other important governance reforms even ones that might be expected to be complementary to decentralizing initiatives

overeducation undereducation and the theory of career mobility the theory of career mobility sicherman and galor journal of political economy 98 1 169 92 1990 claims that wage penalties for overeducated workers are compensated by better promotion prospects sicherman journal of labour economics 9 2 101 22 1991 was able to confirm this theory in an empirical study using panel data however the only retest using panel data so far robst eastern economic journal 21 539 50 1995 produced rather ambiguous results in the present paper random effects models to analyse relative wage growth are estimated using data from the german socio economic panel it is found that overeducated workers in germany have markedly lower relative wage growth rates than adequately educated workers the results cast serious doubt on whether the career mobility model is able to explain overeducation in germany the plausibility of the results is supported by the finding that overeducated workers have less access to formal and informal on the job training which is usually foun

skill mismatch and unemployment in oecd countries marco manacorda this paper uses evidence on employment labour force and wage differentials by education from oecd countries to investigate the characteristics and the consequences of a skill biased shift in the structure of labour demand and supply the empirical analysis shows that there has been some increase in skill mismatch in a few oecd countries over the past two decades but this has not been a generalized phenomenon moreover the rise in mismatch cannot explain much of the rise in unemployment in continental europe while it does explain a significant proportion of the increase in the rate of joblessness in britain

a theory of career mobility this paper analyzes theoretically and empirically the role and significance of occupational mobility in the labor market focusing on individuals careers it provides additional dimensions to the analysis of investment in human capital wage differences across individuals and the relationships among promotions quits and interfirm occupational mobility it is shown that part of the returns to education is in the form of higher probabilities of occupational upgrading within or across firms given an origin occupation schooling increases the likelihood of occupational upgrading furthermore workers who are not promoted despite a high probability of promotion are more likely to quit

does money matter for intergenerational income transmission the intergenerational income elasticity iie is a crucial measure of income mobility in this article we develop a structural model to examine the channels through which this elasticity operates using data from the panel study of income dynamics we separately identify the human capital and the financial components the human capital component examines the transmission of human capital independent of financial investments whereas the financial component examines the impact of income that is uncorrelated with human capital that is exogenous income using a two stage framework we show that the iie operates through both channels moreover our estimates show that the financial component may have a larger effect than previously estimated plausibly attributing to 36 of intergenerational income transmission indeed this result holds even when the financial component is defined in an incredibly narrow manner this suggests that cash payments could promote intergenerational mobility

job mismatches and career mobility does over education assist or hinder occupational advancement career mobility theory hypothesizes that over education leads to a higher level of occupational advancement and wage growth over time

overeducation undereducation and asymmetric information in occupational mobility due to short term asymmetric information overeducated and undereducated workers are shown to have different optimal strategies in seeking upward occupational mobility into their next positions undereducated workers typically have other human capital strengths but these strengths are not marketable to outsiders overeducated workers typically have other human capital weaknesses that are not apparent to outsiders while their excess schooling is marketable in labour markets with dynamic asymmetric information this article presents empirical evidence showing that job tenure increases the probability of upward occupational mobility more if individuals are undereducated moreover the probability of finding upward occupational mobility is increased by overeducated workers engaging in firm switching this article also validates prior empirical studies finding overeducated workers more likely to self report engaging in firm switching activities and more likely to experience upward occupational mobility than o

a possibilistic mean semivariance entropy model for multi period portfolio selection with transaction costs abstract this paper deals with a multi period portfolio selection problem with fuzzy returns a possibilistic mean semivariance entropy model for multi period portfolio selection is presented by taking into account four criteria viz return risk transaction cost and diversification degree of portfolio in the proposed model the return level is quantified by the possibilistic mean value of return the risk level is characterized by the lower possibilistic semivariance of return and the diversification degree of portfolio is measured by the originally presented possibilistic entropy furthermore a hybrid intelligent algorithm is designed to obtain the optimal portfolio strategy finally the comparison analysis between the possibilistic entropy model and the proportion entropy model is provided by two numerical examples to illustrate the efficiency of the proposed approaches and the designed algorithm

portfolio rebalancing model with transaction costs based on fuzzy decision theory the fuzzy set is one of the powerful tools used to describe an uncertain environment as well as quantifying any potential return and risk portfolio liquidity is taken into account and a linear programming model for portfolio rebalancing with transaction costs is proposed the level of return that an investor might aspire to the risk and the liquidity of portfolio are vague in an uncertain financial environment considering them as fuzzy numbers we propose a portfolio rebalancing model with transaction costs based on fuzzy decision theory an example is given to illustrate the behavior of the proposed model using real data from the shanghai stock exchange

overeducation in the labor market this article examines the reasons for the observed discrepancy between workers actual and required levels of schooling and the resulting differences in returns to schooling overeducated workers are found to be younger and to have lower amounts of on the job training than workers with the required level of schooling they also have higher rates of firm and occupational mobility characterized by movement of higher level occupations the findings suggest that overeducation can be explained by the trade off between schooling and other components of human capital and by the mobility patterns of overeducated workers

overeducation in the labour market abstract this paper presents a review of the literature on overeducation the paper assesses the consistency of overeducation within the context of a number of theoretical frameworks including human capital theory hct and assignment theory the analysis goes on to discuss the various measurement controversies associated with the study of overeducation in order to provide an assessment of the extent to which the impacts of the phenomenon represent an economic reality as opposed to a statistical artefact after reviewing the literature it is concluded that the impacts of overeducation are likely to be non trivial and that the phenomenon may potentially be costly to individuals and firms as well as the economy more generally the existence of overeducation also raises some doubts with respect to the validity of some of the central assumptions and predictions of hct that are unlikely to be fully explained by gaps in the standard wage equation framework

overeducation undereducation and the british labour market this paper addresses the issue of overeducation and undereducation using for the first time a british dataset which contains explicit information on the level of required education to enter a job across the generality of occupations three key issues within the overeducation literature are addressed first what determines the existence of over and undereducation and to what extent are over and undereducation substitutes for experience tenure and training second to what extent are over and undereducation temporary or permanent phenomena third what are the returns to over and undereducation and do certain stylized facts discovered for the us and a number of european countries hold for britain

education and skills mismatch in the italian graduate labour market this paper focuses on education and skills mismatch among italian graduates indicators for over and under utilization of education and under utilization of skills are included as explanatory factors in a wage equation testing theories that could explain the effect of over schooling on wages we find little evidence to support assignment theory and also identify a relatively weak wage effect arising from educational mismatch associated with employers as opposed to employees perceptions of the job requirements our interpretation is that some employers have re categorized jobs as requiring a degree when they were previously filled by non graduates and many have not altered pay scales accordingly
