market heterogeneity and the determinants of paris apartment prices a quantile regression approach in this paper the heterogeneity of the paris apartment market is addressed for this purpose quantile regression is applied with market segmentation based on price deciles and the hedonic pri

is there a glass ceiling in sweden using 1998 data we show that the gender log wage gap in sweden increases throughout the wage distribution and accelerates in the upper tail we interpret this as a strong glass ceiling effect we use quantile regression decompositions to examine whether this pattern can be ascribed primarily to gender differences in labor market characteristics or in the rewards to those characteristics even after extensive controls for gender differences in age education both level and field sector industry and occupation we find that the glass ceiling effect we see in the raw data persists to a considerable extent

exploring spatial dynamics with land price indexes the purpose of this study is to explore the within region spatial dynamics of appreciation and depreciation rates using three different representations of geographical space mean value indexing methods are used to construct global land price indexes sub market land price indexes and local land price indexes using transaction price data for vacant residential land within the city of hamilton ontario between 1995 and 2003 the results are validated against statistics canada s series of new housing price indexes followed by a comparison of the relative performance of the three geographical representations of land price indexes the results indicate that the mean value indexing methods are robust although subject to outliers and sample selection bias and clearly illustrate the spatial dynamics of annual appreciation and depreciation rates across the study area the results also underscore the need for regular surveillance of the spatial dynamics of urban land markets

the economics of poverty traps and persistent poverty an asset based approach abstract longitudinal data on household living standards open the way to a deeper analysis of the nature and extent of poverty while a number of studies have exploited this type of data to distinguish transitory from more chronic forms of income or expenditure poverty this paper develops an asset based approach to poverty analysis that makes it possible to distinguish deep rooted persistent structural poverty from poverty that passes naturally with time due to systemic growth processes drawing on the economic theory of poverty traps and bifurcated accumulation strategies this paper briefly discusses some feasible estimation strategies for empirically identifying poverty traps and long term persistent structural poverty as well as relevant extensions of the popular foster greer thorbecke class of poverty measures the paper closes with reflections on how asset based poverty can be used to underwrite the design of persistent poverty reduction strategies

changes in the u s wage structure 1963 1987 application of quantile regression the 1980 s witnessed rapid changes in the structure of wages in the united states in this study recently developed techniques for quantile regression are applied to every march current population survey since 1964 and changes in the return to schooling and experience at different points of the wage distribution are examined the quantile regression technique parsimoniously describes the entire conditional wage distribution this conditional distribution is used to examine changes in within group wage inequality as measured by the difference between conditional quantiles two linear models are considered a simple one group model and a 16 group model the results suggest that the returns to schooling and experience differ across quantiles of the wage distribution but their patterns of change are similar significant differences in wage inequality are also found across the various skill groups the paper also presents a new imputation method for cps data

social capital and coping with economic shocks an analysis of stunting of south african children abstract south african households live in an environment characterized by risks and many face a significant probability of experiencing economic losses that threaten their daily subsistence using household panel data that include directly solicited information on economic shocks and employing household fixed effects estimation we explore how well households cope with shocks by examining the effects of shocks on child nutritional status unlike in the idealized village community some households appear unable to insure against risk particularly when others in their communities simultaneously suffer large losses households in communities with more social capital however seem better able to weather shocks

moral hazard and nonmarket institutions dysfunctional crowding out or peer monitoring the authors examine a situation in which insurance is characterized by moral hazard when market insurance is provided supplementary mutual assistance between family and friends unobservable to market insurers will occur when nonmarket insurers have no better information than market insurers the mutual assistance not only crowds out market insurance but is also harmful and therefore dysfunctional alternatively when nonmarket insurers can observe each other s effort perfectly mutual assistance is beneficial these results point to the potential importance of peer monitoring mechanisms in mitigating moral hazard copyright 1991 by american economic association

a hedonic approach to residential succession a model of neighborhood turnover drawn from bond and coulson 1989 is proposed the type of turnover process that is obtained is shown to depend mainly on the hedonic bid functions for housing and neighborhood quality a demand system of four hedonic attributes is estimated the main results are that the traditional model of filtering by age of unit does not occur and that filtering by housing size does tipping due to changes in median neighborhood income is also quite possible tipping through changes in racial composition appears less likely copyright 1990 by mit press

the dynamics of intraurban quantile house price indexes estimating price indexes for different quantiles shows how prices vary for homes that are in different stages of the filtering process the paper describes a filtering model and its implication for the dynamic interaction of housing prices at these various stages a time series analysis of quantile price indexes for three municipalities near chicago supports the predictions of the filtering model

can tax loss selling explain the january effect a note the january effect remains an unexplained phenomenon in financial economics that the month of january has consistently shown higher mean stock returns than other months has been documented by several researchers beginning with rozeff and kinney 19 additional research by keim 14 showed that approximately half the annual size effect is attributable to abnormal returns in january 1 roll 18 confirmed keim s results as has subsequent research such as lakonishok and smidt 15 2 the most often advanced explanation for the january effect is tax motivated transactions 3 first proposed in 1942 by wachtel 21 the tax loss selling hypothesis is frequently advocated in the popular press as a major influence on stock price behavior essentially this hypothesis states that investors seek to reduce their taxes by realizing losses at year end thereby depressing stock prices stocks return to equilibrium levels after year end providing abnormally high returns in january despite the popularity of the tax loss selling hypothesis it is difficult to justify upon serious reflection justification requires acceptance of the proposition that speculators are prevented from purchasing tax loss candidates before year end with the intention to sell them after year end no theoretical justification has been presented for the hypothesis instead using both theoretical and empirical approaches constantinides 5 argues that such action cannot explain the january effect if the market is efficient 4 his results imply that empirical studies supporting the tax loss selling hypothesis provide evidence of market inefficiency as for the empirical evidence branch 3 dyl 8 roll 18 reinganum 17 and givoly and ovadia 10 have provided support for the tax loss selling hypothesis 5 recently schultz 20 tested the tax explanation by examining the

estimating the demand for the characteristics of housing a hstract estimates of the demand for the characteristics contained in a differentiated product such as housing can be based on hedonic regressions however previous studies have not dealt with several potential problems in such estimation a more appropriate framework for the estimation is provided in this paper also data from a number of cities are used to eliminate the identification problem and the endogeneity of the marginal prices derived from non linear hedonic equations is considered in the estimation the results on own and cross price elasticities expenditure elasticities and the effects of socio economic vafiables accord well with expectations

district house price movements in england and wales 1997 2007 an exploratory spatial data analysis approach using exploratory spatial data analysis and house price data from local authority districts in england and wales this article considers whether a regional ripple effect can be tracked at the district level although spatial house price variation has been explored at a sub regional level this is possibly the first paper to attempt to track house price spillover between districts on a national basis high and low growth clusters of areas are traced it is concluded that spatial spillover of house price growth is unlikely to be based on interlocked markets bonded by commuting or migration alone information flows and expectations are likely to reinforce interdistrict transmission specifically house price spillover north of the east midlands appears much more rapid than would be consistent with a ripple suggesting that there is some support for undertaking british housing market analysis on a spatially segmented basis even at a regional level

religion and economy religion has a two way interaction with political economy with religion viewed as a dependent variable a central question is how economic development and political institutions affect religious participation and beliefs with religion viewed as an independent variable a key issue is how religiosity affects individual characteristics such as work ethic honesty and thrift and thereby influences economic performance in this paper we sketch previous studies of this two way interaction but focus on our ongoing quantitative research with international data

the dynamics of changes in the female wage distribution in the usa a quantile regression approach this paper examines the female wage structure focusing on changes at different points in the wage distribution newly developed quantile regression methods are used in analysing data from the march current population survey the results show that while the most significant changes for the less skilled women took place at the bottom of the wage distribution for the more skilled groups changes occurred at both ends of the distribution consequently wage inequality decreased for the high school graduates and increased for the younger college graduates furthermore the more highly skilled women experienced the steepest gain in wages regardless of their position in the distribution 1998 john wiley sons ltd

exploring poverty traps and social exclusion in south africa using qualitative and quantitative data abstract recent theoretical work hypothesises that a polarised society like south africa will suffer a legacy of ineffective social capital and blocked pathways of upward mobility that leaves large numbers of people trapped in poverty to explore these ideas this paper employs a mix of quantitative and qualitative methods novel econometric analysis of asset dynamics over the 1993 98 period identifies a dynamic asset poverty threshold that signals that large numbers of south africans are indeed trapped without a pathway out of poverty qualitative analysis of this period and the period 1998 2001 more deeply examines patterns of mobility and confirms the continuation of this pattern of limited upward mobility and a low level poverty trap in addition the qualitative data permit a closer look at the specific role played by social relationships while finding ample evidence of active social capital and networks these are more helpful for non poor households for the poor social capital at best helps sta

pretending to be poor borrowing to escape forced solidarity in cameroon abstractfrom field observations of credit cooperatives in cameroon we find that 19 of the loans taken are fully collateralized by savings held in the same institutions this behavior is costly to the borrower as it represents a net interest payment of about 24 per year while traditional explanations may partly explain this behavior interviews with members of the cooperatives suggest the following new rationale members resort to borrowing to signal to friends and relatives that they are poor and do not have savings available by doing so they can avoid requests for financial help we develop a signaling model to analyze the conditions under which this behavior is an equilibrium outcome

a dark side of social capital kinship consumption and savings abstract we explore whether traditional sharing norms in kinship networks affect consumption and accumulation decisions of poor black households in kwazulu natal south africa using a proxy for the number of family dependents our results are consistent with the interpretation that households try to evade their sharing obligations by i accumulating durables that are non sharable at the expense of durables that may be shared and ii reducing savings in liquid assets by attenuating accumulation incentives kinship sharing may come at the expense of income growth if so a culturally induced poverty trap can possibly eventuate we demonstrate tentative evidence that more extensive kinship networks are associated with lower incomes

trust membership in groups and household welfare evidence from kwazulu natal south africa unfortunately these two literatures have remained largely unconnected the group and network literature concludes that participation has important economic benefits even when the stated function of the group is noneconomic in most cases however the mechanisms by which groups and networks achieve this are unclear the determinants of trust and participation in groups literature highlights the importance of income and social homogeneity what remains less understood is whether and how trust can be generated for example via participation in groups this article links the empirical literatures referenced above by exploring the relationship between membership in groups and trust specifically using longitudinal data from kwazulu natal province south africa we examine 1 the importance of trust in the decision to join groups 2 the subsequent ability of groups to generate trust and 3 the effect of group membership and trust on a measure of well being per capita household income in addition we disaggregate groups into financial and nonfinancial and we categorize trust in people by agent or actor therefore we can explore whether trust in different kinds of actors is important for participation in different kinds of groups and whether participation in different kinds of groups is important for generating trust in different kinds of actors excerpt

what do we learn about consumer demand patterns from micro data the aim of this paper is to assess the importance of using micro level data in the econometric analysis of consumer demand to do this we utilize a time series of repeated cross sections covering some 4 000 households in each of 15 years employing a number of different aggregation procedures we conclude that aggregate data alone are unlikely to produce reliable estimates of structural price and income coefficients however once certain aggregation factors as well as trend and seasonal components are included an aggregate model is not necessarily outperformed across all demand equations in terms of forecasting ability jel d12 c52 c31 the purpose of this paper is to develop a complete consumer demand system based on a time series of individual household data and to use it to measure the biases introduced into the study of consumer de mand behavior when aggregate data are used in place of the appropriate microeco nomic data we assess the suitability of ag gregate data through the impact on income and price elasticities and by evaluating the ability of both micro and aggregate based models to forecast aggregate consumer de mand the biases introduced by the use of aggregate data depend upon the way that household characteristics interact with in come and price effects and on departures of demand systems from linearity we explore the structure of microeconomic demand sys tems and the role of household characteris tics in the behavior of consumer demand both for the light this may shed on the pattern of future demands and for the im plications this behavior has for issues of aggregation consumer demand patterns typically found in micro data sets vary considerably across households with different household characteristics and with different levels of income we model this variability by making intercept and slope parameters in the budget share equations of our demand sys tem depend on household characteristics and by allowing for nonlinear total log expenditure terms in fact in theory consistent demand systems it is total ex penditure rather than disposable income that is allocated across goods we find that this general framework leads to a well specified data coherent demand system which is a quadratic extension of the popu lar almost ideal model of angus s deaton and john muellbauer 1980 the micro level estimates are shown to be sensitive to the treatment of endogeneity of total expen diture and to the specification of interaction terms with household characteristics in ad dition this specification is also shown to possess many attractive features for the evaluation of aggregate models

hedonic prices and implicit markets estimating demand and supply functions for differentiated products in choosing the level of quality to purchase the buyer of a differentiated product also chooses a point on the marginal price schedule for that product hence in general the demand functions for product characteristics cannot be consistently estimated by ordinary least squares market equilibrium results in a matching of characteristics of demanders and suppliers this matching restricts the use of buyer and seller characteristics as instruments when estimating demand and supply functions for product characteristics the paper develops these issues a stochastic structure for hedonic equilibrium models is then proposed identification results are presented and estimation procedures are outlined
