permanent income hedonic prices and demand for housing new evidence abstract housing demand is examined by looking quite specifically at the income and price variables based on individual household data permanent and transitory incomes are computed through instrumental variables related to human and nonhuman wealth a price is constructed by spatially varying hedonic techniques separation of measured income into permanent and transitory components substantially improves the predictive power of the housing demand estimation and leads to demand elasticities of 1 and 1 with respect to permanent income and price the permanent income elasticity is roughly twice the measured income elasticity

the wait and see option in ascending price auctions ascending auctions offer agents the option to wait and see before deciding to drop out we show that in contexts where as time proceeds agents get finer and finer estimates of their valuations incentives to drop out at one s expected valuation are weak it is optimal for agents to wait and see we first illustrate the claim in a private value setting we next analyze an interdependent value setting in which this wait and see option results in an imperfect information aggregation we also analyze the implications for the seller s revenue and show that the ascending format may dominate the second price format independently of the date at which the second price auction is run jel d44 d83

inequality and the impact of growth on poverty comparative evidence for sub saharan africa abstract this study explores the extent to which inequality affects the impact of income growth on the rates of poverty changes in sub saharan africa ssa compared to non ssa based on an unbalanced panel of 86 countries over 1977 2004 for all three measures of poverty headcount gap and squared gap the impact of gdp growth on poverty reduction is a decreasing function of initial inequality the impacts are similar in direction for ssa and non ssa so that within both regions there are considerable disparities in the responsiveness of poverty to income growth depending on inequality nevertheless the income growth elasticity is substantially less for ssa implying relatively small poverty reduction response to growth

comparative analysis of the social demographic and economic factors that influenced housing choices in spain in 1990 and 2000 the housing market is an important sector in the economy of any country residential demand also referred to as housing consumption depends on many demographic and social characteristics of the country s population and is also related to economic factors the aim of the present paper was to evaluate the joint effects of economic demographic and social factors on household behaviour with respect to housing choices in addition an attempt was made to determine the impact of recent economic and structural changes in spanish society in 1990 and 2000 on residential demand it was found that the consequences of these structural changes will have medium and long term effects on housing demand and that the current economic situation has significantly affected the short term changes in this demand

hiding information in open auctions with jump bids we analyse a rationale for hiding information in open ascending auction formats we focus on the incentives for a bidder to call a price higher than the highest standing one in order to prevent the remaining active bidders from aggregating more accurate information by observing the exact dropout values of the opponents who exit the auction we show that the decision whether to allow jump bids or not can have a drastic impact on revenue and efficiency

reducing child malnutrition how far does income growth take us how rapidly will child malnutrition respond to income growth this article explores that question using household survey data from 12 countries as well as data on malnutrition rates in a cross section of countries since the 1970s both forms of analysis yield similar results increases in income at the household and national levels imply similar rates of reduction in malnutrition using these estimates and better than historical income growth rates the article finds that the millennium development goal of halving the prevalence of underweight children by 2015 is unlikely to be met through income growth alone what is needed to accelerate reductions in malnutrition is a balanced strategy of income growth and investment in more direct interventions

the unequal geographic burden of federal taxation in the united states workers in cities offering above average wages cities with high productivity low quality of life or inefficient housing sectors pay 27 percent more in federal taxes than otherwise identical workers in cities offering below average wages according to simulation results taxes lower long run employment levels in high wage areas by 13 percent and land and housing prices by 21 and 5 percent causing locational inefficiencies costing 0 23 percent of income or 28 billion in 2008 employment is shifted from north to south and from urban to rural areas tax deductions index taxes partially to local cost of living improving locational efficiency

what are cities worth land rents local productivity and the total value of amenities abstract this paper models how to use widely available data on wages and housing costs to infer land rents local productivity and the total value of local amenities in the presence of federal taxes and locally produced nontraded goods i apply the model to u s metropolitan areas with the aid of visually intuitive graphs the results improve measures of productivity and feature large differences in land rents wage and housing cost differences across metropolitan areas are accounted for more by productivity than quality of life differences regressions using individual amenities reveal that the most productive and valuable cities are typically coastal sunny mild educated and large

credit rationing and the demand for owner occupied housing abstract this study applies cross sectional data to test whether default risk induced credit constraints affect the demand for owner occupied housing credit constrained households are argued to exhibit different elasticities of demand for housing than less constrained households housing demand elasticities are then estimated separately for households obtaining va insured and non va loans the government guarantee on va loans insures lenders against default enabling lenders to apply easier nonprice terms of credit results indicate that observed demand elasticities differ significantly across va and conventional mortgage holders that marginal changes in credit constraints affect housing demand and that fha financing mitigates the effect of mortgage constraints

a theory of jump bidding in ascending auctions abstract jump bidding is a commonly observed phenomenon that involves bidders in ascending auctions submitting bids higher than required by the auctioneer such behavior is typically explained as due to irrationality or to bidders signaling their value we present field data that suggests such explanations are unsatisfactory and construct an alternative model in which jump bidding occurs due to strategic concerns and impatience we go on to examine the impact of jump bidding on the outcome of ascending auctions in an attempt to resolve some policy disputes in the design of ascending auctions

promotion turnover and preemptive wage offers this paper examines the strategic promotion and wage decisions of employers when employees may be more valuable to competing firms competing employers must incur a cost to learn the quality of their match with a manager promotion signals that workers are potentially valuable managers in other firms and so can lead to turnover to preempt competition for a manager an employer may offer a wage high enough to discourage competitors from acquiring information and bidding up the wage further or hiring the worker away this transfers wages from good workers to bad more costly information acquisition yields greater expected lifetime wages copyright 1993 by american economic association

auctions and information acquisition sealed bid or dynamic formats the value of an asset is generally not known a priori and it requires costly investments to be discovered in such contexts with endogenous information acquisition which selling procedure generates more revenues we show that dynamic formats such as ascending price or multistage auctions perform better than their static counterpart this is because dynamic formats allow bidders to observe the number of competitors left throughout the selling procedure thus even if competition appears strong ex ante it may turn out to be weak along the dynamic format thereby making the option to acquire information valuable this very possibility also induces the bidders to stay longer in the auction just to learn about the state of competition both effects boost revenues and our analysis provides a rationale for using dynamic formats rather than sealed bid ones

replicative evidence on the demand for owner occupied and rental housing some important results in urban economic theory and policy analysis rest upon housing demand and its associated price and income elasticities the extent to which the affluent choose to live away from the city s center thus increasing their commuting time depends on the relative income elasticities of housing demand and valuation of leisure in a more policy oriented framework the relative efficacies of income as opposed to housing price subsidies for low income households depend on the relative values of income and price elasticities

costly signalling in auctions this paper analyses a dynamic auction in which a fraction of each bid is sunk jump bidding is used by bidders to signal their private information bluffing respectively sandbagging occurs when a weak respectively strong player seeks to deceive his opponent into thinking that he is strong respectively weak a player with a moderate valuation bluffs by making a high bid and drops out if his bluff is called a player with a high valuation should vary his bids and should sometimes sandbag by bidding low to induce lower bids by his rival

preemptive bidding and pareto efficiency in takeover auctions this paper extends the fishman 1988 model of preemptive jump bidding in private value takeover auction to auctions with common and affiliated values we show that in the presence of a common value component jump bidding equilibrium results in higher social surplus furthermore we show that under certain conditions allowing for preemptive jump bidding in common value auctions results in ex ante pareto improvement

why do sellers usually prefer auctions we compare the most common methods for selling a company or other asset when participation is costly a simple simultaneous auction and a sequential process in which potential buyers decide in turn whether to enter the bidding the sequential process is always more efficient but preemptive bids transfer surplus from the seller to buyers because the auction is more conducive to entry precisely because of its inefficiency it usually generates higher expected revenue we also discuss the effects of lock ups matching rights break up fees as in takeover battles entry subsidies etc

home ownership and unemployment in the us in this paper we scrutinise oswald s evidence that home ownership and unemployment are correlated across the us states in order to abstract from state fixed effects in levels we analyse the cross sectional variation in changes in home ownership and unemployment rates between 1970 and 1990 after duplicating nearly oswald s result we illustrate the importance of weighting the state observations by the fraction of total us households in 1970 that resided in the respective states and of abstracting from the ageing of the population between 1970 and 1990 this causes oswald s correlation to to disappear secondly we estimate the relationship for six different age classes and for household heads and total population we find that the relationship is non existent for both young households and old households but exists for middle aged households young households have accumulated little wealth and have had less time to become attached to the geographical area than middle aged households and thus are more

housing demand and community choice an empirical analysis abstract housing demand reflects the household s simultaneous choice of the neighborhood whether to own or rent the dwelling and the quantity of housing services demanded existing literature emphasizes the final two factors but overlooks the choice of community this paper develops an econometric model that incorporates all three components and then estimates this model using a sample of tampa florida households incorporating community choice increases the price elasticity of demand and reduces the differential between white and comparable nonwhite households the results are robust to the inclusion of permanent income and taxes

functional form sample selection and housing demand abstract this paper addresses issues of functional form and sample selection in estimating housing demand urban economic theory suggests that income and price elasticities be allowed to vary with reference incomes and housing prices a generalized box cox estimator rejects linear and log log forms semi log forms are accepted in some cases sample truncation leads to downward biases in permanent income regressions but to slightly upward biased income elasticities price elasticities are generally unchanged

an econometric model of housing price permanent income tenure choice and housing demand abstract this paper addresses the determination of housing price permanent income tenure choice and housing demand full housing demand elasticities incorporate the interactive effects among the four stages of the model price and income have major effects in the tenure choice equation sociodemographic variables such as age have complex effects that may be lost in simpler forms of estimation

does child undernutrition persist despite poverty reduction in developing countries quantile regression results abstract the eradication of child undernutrition and extreme poverty are important objectives for most societies countries with higher national incomes usually improve in both dimensions but not always at the same rate using quantile regression we show that poverty rates tend to decline with increased income at a roughly constant elasticity in contrast while the prevalence of child wasting declines at that same elasticity where it is most widespread the elasticity becomes smaller as wasting becomes less prevalent this finding suggests a greater need for increasingly targeted interventions to achieve a given reduction in undernutrition as its prevalence declines

demographic variables in demand analysis in this paper the authors discuss five procedures for incorporating demographic variables into theoretically plausible demand systems translating scaling and the gorman reverse gorman and implicit prais houthakker procedures these five procedures are used to incorporate a single demographic variable the number of children in a household into the generalized ces demand system using household budget data for the united kingdom for the period 1966 1972 excerpt

why is consumption more log normal than income gibrat s law revisited significant departures from log normality are observed in income data in violation of gibrat s law we identify a new empirical regularity which is that the distribution of consumption expenditures across households is within cohorts closer to log normal than the distribution of income we explain these empirical results by showing that the logic of gibrat s law applies not to total income but to permanent income and to maginal utility these findings have important implications for welfare and inequality

jump bidding strategies in internet auctions abidding strategy commonly observed in internet auctions is that of jump bidding or entering a bid larger than what is necessary to be a currently winning bidder in this paper we argue that the cost associated with entering online bids and the uncertainty about future entry both of which distinguish internet from live auctions can explain this behavior we present a simple theoretical model that includes the preceding characteristics and derive the conditions under which jump bidding arises in a format commonly used for online trading the ascending price auction we also present evidence recorded from hundreds of internet auctions that is consistent with some of the basic predictions from our model we find that jump bidding is more likely earlier in an auction when jumping has a larger strategic value and that the incentives to jump bid increase as competition increases our results also indicate that jump bidding is effective jump bidders place fewer bids overall and increased early jump bidding deters entry later in the auction we also discuss possible means of reducing bidding costs and evidence that internet auctioneers are pursuing this goal

when should sellers use auctions the simultaneous bid auction is a standard method for sellers to solicit offers from buyers a simple alternative is for a seller to ask buyers to make offers sequentially if it is costly for buyers to participate the sequential mechanism will tend to be more efficient than the simultaneous auction because later potential buyers can condition their participation decisions on earlier bids however the sequential mechanism s greater efficiency may not produce higher revenues because while the possibility of deterring later potential entrants can lead early bidders to bid aggressively the fact that later firms might be deterred will tend to reduce revenues the relative revenue performance of the mechanisms will therefore depend on whether the threat of potential future competition which can raise bids in the sequential mechanism is more valuable to the seller than actual competition which will tend to be greater in the simultaneous auction the relative revenue performance of these alternative mechanisms has direct implications for how assets should be sold in the case of how to structure the sale of corporations this question has attracted attention from practitioners and commentators since the delaware supreme court s 1986 revlon decision charged a board overseeing the sale of a company with the duty of getting the best price for the stockholders revlon v mcandrews and forbes holdings 1986 in practice

not by growth alone the role of the distribution of income in regional diversity in poverty reduction this study examines the role of the distribution of income in determining the responsiveness of poverty to income growth and changes in income inequality using panel data of 58 developing countries for the period 1980 1998 we show that the large cross regional variation in the capacity of income growth to reduce poverty i e the income elasticity is largely explained by differences in the initial distribution of income and present region and time specific estimates of the income and gini elasticities of poverty we find that the income elasticity of poverty in the mid 1990s equals 1 31 on average and ranges from 0 71 for sub saharan africa to 2 27 for the middle east and north africa and that the gini elasticity of poverty equals 0 80 on average and ranges from 0 01 in south asia to 1 73 in latin america furthermore we show that while differing income growth rates account for most of the regional diversity in poverty trends the additional impact of differences across regions in rates of inequality change and income and inequality elasticities of poverty is almost always significant and far too large to be ignored most notably so in eastern europe and central asia

neighbourhood effects and housing demand in this paper we estimate a model of housing demand with neighborhood eects we exploit special features of the national sample of the american housing survey and properties of housing markets that allow us to create natural instruments and therefore identify the impact of social interactions we find evidence of both endogenous and contextual neighborhood eects we report two alternative sets of estimates for neighborhood eects that dier in terms of the instruments we use for estimating the model when the endogenous neighborhood eect is large the respective contextual eects are weak and vice versa the elasticity of housing demand with respect to the mean of the neighbors housing demands the endogenous eect ranges from 0 19 to 0 66 and is generally very significant the contextual eects are also very significant a key such eect the elasticity with respect to the mean of neighbors permanent incomes ranges from 0 17 to 0 54

demographic effects in demand analysis estimation of the quadratic expenditure system using microdata the purpose of this paper is to estimate a complete theoretically plausible system of demand equations on microdata using the rich detail of these data to investigate the impact of demographic variables on demand behavior the system which we estimate is the quadratic expenditure system qes introduced by howe pollak and wales we evaluate four methods for incorporating demographic variables into the demand system three of these procedures imply parameter restrictions while the fourth does not tests on the restrictions imply that for our data unrestricted estimation yields significantly greater explanatory power

the measurement and trend of housing inequality in the united states 1978 85 inequality in housing services for renters owners and all households in the united states is estimated for 1978 and 1985 hedonic techniques are applied to data from the american housing survey to derive values for housing services that include publicly provided as well as subsidized housing we find significant disparities in housing but substantially less inequality than in incomes in 1978 the top decile garnered 19 2 of housing services while the bottom decile received only 5 1 the trend however is towards greater equality in housing with large and statistically significant shifts across all deciles by 1985 the share of the top decile dropped to 16 3 a percentage decrease in share of 15 3 while that of the bottom decile rose to 5 7 a percentage increase of 11 4

lifetime income and housing affordability in singapore most commonly used measures of housing affordability are essentially short run indicators that compare current income with house prices or housing costs despite the emphasis in the literature on t

halving global poverty the goal of central importance to this paper is to cut in half the proportion of people living below 1 a day from around 30 percent of the developing world s population in 1990 to 15 percent by 2015 based on population projections in 1990 this would correspond to around one billion people exiting poverty this paper begins by discussing poverty trends on a global scale where the poor are located in the world and how their numbers have been changing over time it then discusses the relationship of economic growth and income distribution to poverty reduction finally it suggests an evidence based agenda for poverty reduction in the developing world full text available at official url

theory and estimation in the economics of housing demand the main purpose of this paper is to review recent theoretical and empirical developments in the economics of housing demand in particular we ask what is known concerning the permanent income elasticity of housing demand vis a vis the current or measured income elasticity what is known concerning price elasticities what is the appropriate functional form for housing demand equations what is the role of demographic variables what is known concerning dynamic aspects of housing demand what appear to be the major sources of bias in existing estimates of demand equations

does inflation affect real behavior the case of housing an important tradition in economics is to assume that demand depends upon relative prices and is homogenous of degree zero for the most part this has been interpreted as meaning inflation changes in the price level leaves demand unchanged recent work by a number of economists has challenged this position for the case of housing demand two arguments have been made that inflation acting in concert with existing institutions alters the quantity of housing demanded and the decision to rent or own a house the first argument states that inflation and the standard fixed payment mortgage combine to reduce the size of the mortgage loan a household can obtain for the purpose of buying a home this works to reduce the quantity of owner occupied housing demanded given the importance of mortgage finance to the demand for owner occupied housing the second argument focuses on the inflation adjusted after tax cost of owner occupied housing it simply states that an increase in the rate of anticipated inflation of the general price level reduces the after tax cost of housing thus increasing the demand for housing and the demand for homeownership there has been little empirical testing of these two arguments the purpose of this paper is to formulate and estimate a model which will give an indication of the quantitative significance of the two arguments a housing demand equation and a tenure choice equation own versus rent are estimated using a sample of about 6000 households from the 1975 annual housing survey 10 the estimates suggest that inflation dampens housing demand and homeownership opportunity for most households even though the inflation adjusted after tax cost of owner occupied housing declines as inflation heats up the paper consists of six sections including the introduction section two examines the ways inflation affects housing choices in more detail the third section contains the specification of the econometric model that forms the basis of the study section four is a discussion of econometric problems and the data used the results of the estimates are discussed in the fifth section the paper concludes with a presentation of the major conclusions and policy implications of the study

how potent is economic growth in reducing undernutrition what are the pathways of impact new cross country evidence this article uses panel data from 63 developing countries over the period 1970 96 to explore the relationship between income growth and child undernutrition rates it has two broad objectives the first is to determine how strong the relationship is whether it is causal and the magnitude of the contribution the income growth has made to reductions in child undernutrition over the past 25 years the second broad objective is to examine the specific pathways through which income growth affects undernutrition the article represents the first effort to merge child undernutrition rates by year for multiple years with the various determinants of child undernutrition it thus allows for estimations that take into account country specific characteristics also for the first time the study 1 tests for the endogeneity of potential determinants 2 calculates the historical contribution of longrun income growth to reductions in child undernutrition and 3 identifies the pathways through which income growth affects undernutrition section ii discusses the determinants of child nutritional status from a conceptual standpoint section iii describes the variables employed the data and the estimation strategy the results are presented in section iv and section v concludes with a discussion of the implications of the results for policies to reduce child undernutrition excerpt

the evolving role of agriculture in poverty reduction an empirical perspective abstract the role of agriculture in development remains much debated this paper takes an empirical perspective and focuses on poverty as opposed to growth alone the contribution of a sector to poverty reduction is shown to depend on its own growth performance its indirect impact on growth in other sectors the extent to which poor people participate in the sector and the size of the sector in the overall economy bringing together these different effects using cross country econometric evidence indicates that agriculture is significantly more effective in reducing poverty among the poorest of the poor as reflected in the 1 day squared poverty gap it is also up to 3 2 times better at reducing 1 day headcount poverty in low income and resource rich countries including those in sub saharan africa at least when societies are not fundamentally unequal however when it comes to the better off poor reflected in the 2 day measure non agriculture has the edge these results are driven by the much larger participation of poorer households in growth from agriculture and the lower poverty reducing effect of non agriculture in the presence of extractive industries

a joint model of tenure choice and demand for housing in the city of karachi the paper estimates a joint model of tenure choice and demand for housing for the city of karachi pakistan using a two stage estimation procedure permanent income and demographic variables are included in the analysis the study uses data collected at the household level in the city in 1987 88 results show that ownership rates are high in karachi ownership is more likely with increases in permanent income age household size and residence in the unauthorised areas permanent income transitory income age and education of the head significantly affect the consumption of housing both for renter and owner households results of the analysis and the estimated income elasticities of demand are comparable and consistent with those reported for other developing countries

the simultaneous ascending auction dynamics of price adjustment in experiments and in the uk3g spectrum auction we develop a model of the behavior of bidders in simultaneous ascending auctions based on two principles principle of surplus maximization and principle of bid minimization these principles lead to models of both price dynamics and equilibration leading to disequlibrium structural equations that can be used for estimating bidder values the intention behind the development of this methodology is to provide an auctioneer a method of extracting information during an auction about possible closing prices we benchmark the performance of the model with data from experimental auctions and then apply it to the uk umts or third generation mobile auction

the demand for housing in spain an endogenous switching regression analysis housing demand in spain has been studied by using data disaggregated into primary and secondary housing demands it is found that demand for both types of housing area indeed related and that they are both considered necessities thus suggesting that their consumption ought to be modelled as a joint decision moreover it is found that traditional determinants of housing demand affect primary and secondary home demands differently these differences are attributable to the following economic rationales need for asset holdings diversifications relative high cost of home ownership versus rental in choice locations and differences in land demand intensity across regions in sum the findings suggest that policy makers in spain contrary to popular beliefs must consider secondary homes an integral part of households accommodation need
