teacher quality in educational production tracking decay and student achievement growing concerns over the inadequate achievement of u s students have led to proposals to reward good teachers and penalize or fire bad ones the leading method for assessing teacher quality is value added modeling vam which decomposes students test scores into components attributed to student heterogeneity and to teacher quality implicit in the vam approach are strong assumptions about the nature of the educational production function and the assignment of students to classrooms in this paper i develop falsification tests for three widely used vam specifications based on the idea that future teachers cannot influence students past achievement in da ta from north carolina each of the vams exclusion restrictions are dramatically viola ted in particular these models indicate large effects of 5th grade teachers on 4th grade t est score gains i also find that conventional measures of individual teachers value added fade out very quickly and are at best weakly related to long run effects i discuss implic ations for the use of vams as personnel tools

fiscal versus traditional market variables in canadian migration this paper evaluates the hypothesis that the influence of traditional market variables on migration in canada has diminished over time this is attributed to a crowding out process whereby growth of social security type programs has cushioned the effects of say unemployment and thus motivation to migrate for jobs and fiscal policies have exerted unintended effects implications are that market forces that would work naturally to induce migration from low to high income regions and thus equalize earned incomes have been short circuited and that traditional tools of manpower policy for influencing migration such as job creation skill enhancement or wages are less effective currently than they might have been in the past

interprovincial migration and local public goods the objective of this paper is to test whether fiscally induced migration occurs in canada that is whether interprovincial migration flows are influenced by government tax and expenditure policies in order to do so a multinominal logit model of migration is developed in which individuals choose to live in the province where their utility would be highest the model is estimated using aggregate data for the period 1962 81 the results indicate that migration is influenced by provincial government spending trough the magnitude and direction of the effect differs with the type of government spending the implication of these results is that intergovernmental transfer payments and provincial natural resource revenues also have the potential to influence migration flows in canada summary in fre excerpt

measuring the impacts of teachers i evaluating bias in teacher value added estimates are teachers impacts on students test scores value added a good measure of their quality one reason this question has sparked debate is disagreement about whether value added va measures provide unbiased estimates of teachers causal impacts on student achievement we test for bias in va using previously unobserved parent characteristics and a quasi experimental design based on changes in teaching sta using school district and tax records for more than one million children we nd that va models which control for a student s prior test scores exhibit little bias in forecasting teachers impacts on student achievement although teachers have substantial impacts

the evolution of high incomes in northern america lessons from canadian evidence this paper uses tax statistics to construct new series on canadian top income shares from 1920 to 2000 and provides a systematic comparison with the u s experience as in the united states top income shares in canada display a ushaped pattern over the century with a precipitous drop during world war ii followed by a slower decline until 1970 since the late 1970s top income shares have been increasing dramatically and the very top shares are now as high as in the pre war era as in the united states the recent increase in top income shares is the consequence of a surge in top wages and salaries the canadian experience since the late 1970s does not appear to be well explained by tax changes suggesting that the upward trend in canada derives from the united states perhaps because many high income canadians have an emigration option this in turn suggests that the recent increase in u s personal income top shares is not merely a change in tax reporting behavior the recent sharp increase in top income shares in canada is of the same magnitude at the individual and family level and is not due to an increase in income mobility

belief based refinements in signalling games abstract there are many economic problems which when modelled as games of incomplete information give rise to many sequential equilibria severely limiting the usefulness of the model there has recently been a large literature devoted to refining the set of equilibria in order to reduce this multiplicity by restricting the set of admissible disequilibrium beliefs this paper argues that the logical foundations of some refinements and the equilibria they focus on are problematic and further proposes an alternative refinement that avoids the difficulties we also provide an existence theorem covering a broad class of signalling games often studied in economics journal of economic literature classification numbers c72 c70 d82

would higher salaries keep teachers in high poverty schools evidence from a policy intervention in north carolina abstract for a three year time period beginning in 2001 north carolina awarded an annual bonus of 1800 to certified math science and special education teachers working in public secondary schools with either high poverty rates or low test scores using longitudinal data on teachers we estimate hazard models that identify the impact of this differential pay by comparing turnover patterns before and after the program s implementation across eligible and ineligible categories of teachers and across eligible and barely ineligible schools results suggest that this bonus payment was sufficient to reduce mean turnover rates of the targeted teachers by 17 experienced teachers exhibited the strongest response to the program finally the effect of the program may have been at least partly undermined by the state s failure to fully educate teachers regarding the eligibility criteria our estimates most likely underpredict the potential outcome of a program of permanent salary differentials operating under complete information

intertemporal price discrimination dynamic arrivals and changing values we study the profit maximizing price path of a monopolist selling a durable good to buyers who arrive over time and whose values for the good evolve stochastically the setting is completely stationary with an infinite horizon contrary to the case with constant values optimal prices fluctuate with time we argue that consumers randomly changing values offer an explanation for temporary price reductions that are often observed in practice

education signalling with preemptive offers offers before workers complete their education workers cannot commit to turning down such offers offers are private so that workers are unable to use one firm s offer in an attempt to elicit better offers from other firms in the unique sequential equilibrium outcome of the model with unproductive education there is no wasteful education when education is productive the standard model predicts that more able individuals become overeducated to separate themselves from less able workers in our model less able workers become overeducated to partially pool with more able workers the pooling mutes the incentives of high ability workers who in consequence actually choose to become undereducated we examine the robustness of our result to modifications to the basic model

pay for percentile we propose an incentive scheme for educators that links compensation to the ranks of their students within comparison sets under certain conditions this scheme induces teachers to allocate socially optimal levels of effort moreover because this scheme employs only ordinal information it allows education authorities to employ completely new assessments at each testing date without ever having to equate various assessments this removes incentives for teachers to teach to a particular assessment form and eliminates opportunities to influence reward pay by corrupting assessment scales education authorities can employ separate no stakes assessment systems to track trends in scaled measures of student achievement jel i21 i28 j33 j45

accountability incentives and behavior the impact of high stakes testing in the chicago public schools the recent federal education bill no child left behind requires states to test students in grades 3 to 8 each year and to judge school performance on the basis of these test scores while intended to maximize student learning there is little empirical evidence about the effectiveness of such policies this study examines the impact of an accountability policy implemented in the chicago public schools in 1996 1997 using a panel of student level administrative data i find that math and reading achievement increased sharply following the introduction of the accountability policy in comparison to both prior achievement trends in the district and to changes experienced by other large urban districts in the mid west however for younger students the policy did not increase performance on a state administered low stakes exam an item level analysis suggests that the observed achievement gains were driven by increases in test specific skills and student effort i also find that teachers responded strategically to the incentives along a variety of dimensions by increasing special education placements preemptively retaining students and substituting away from low stakes subjects like science and social studies

the role of commitment in bilateral trade abstract this paper characterizes the set of equilibrium payoffs in bargaining with interdependent values when the informed party makes all offers as discounting vanishes the seller of a good is informed of its quality which affects both his cost and the buyer s valuation but the buyer is not to characterize this payoff set we derive an upper bound using mechanism design with limited commitment we then prove that this upper bound is tight by showing that all its extreme points are equilibrium payoffs our results shed light on the role of different forms of commitment in bargaining in particular they imply that the buyer s inability to commit before observing the terms of trade is what precludes efficiency

internal and international migration in mexico 1995 2000 using micro data from mexico and us 2000 population censuses and following a multi choice variant of roy s 1951 model this article pools into one model the determinants of internal and international migration in mexico while paying explicit attention to the potential problem of self selection the results reveal that ignoring multiple destinations in the migration decision might lead to erroneous inferences about the determinants of migration and the type of selection after controlling for wage differences the results suggest that single adult men with low schooling levels tend to migrate to the us while married women and men with higher levels of schooling tend to migrate within mexico we also found that there are strong differences between domestic and international social networks

learning about the arrival of sales abstract we analyse optimal stopping when the economic environment changes because of learning a primary application is optimal selling of an asset when demand is uncertain the seller learns about the arrival rate of buyers as time passes without a sale the seller becomes more pessimistic about the arrival rate when the arrival of buyers is not observed the rate at which the seller revises her beliefs is affected by the price she sets learning leads to a higher posted price by the seller when the seller does observe the arrival of buyers she sets an even higher price

selling a lemon under demand uncertainty we consider a seller who has private information about the quality of her good but is uncertain about buyer arrivals assuming that the high quality seller insists on a price we show that the low quality seller s surplus and pricing strategy crucially depend on buyers knowledge about the demand state if they are also uncertain about demand then demand uncertainty increases the low quality seller s expected payoff and her optimal strategy is to lower the price after some time if buyers know the demand state then demand uncertainty does not affect the low quality seller s payoff but she must employ a sophisticated pricing strategy

experimental estimates of education production functions this paper analyzes data on 11 600 students and their teachers who were randomly assigned to different size classes from kindergarten through third grade statistical methods are used to adjust for nonrandom attrition and transitions between classes the main conclusions are 1 on average performance on standardized tests increases by four percentile points the first year students attend small classes 2 the test score advantage of students in small classes expands by about one percentile point per year in subsequent years 3 teacher aides and measured teacher characteristics have little effect 4 class size has a larger effect for minority students and those on free lunch 5 hawthorne effects were unlikely

the effects of exposure to better neighborhoods on children new evidence from the moving to opportunity experiment the moving to opportunity mto experiment offered randomly selected families housing vouchers to move from high poverty housing projects to lower poverty neighborhoods we analyze mto s impacts on children s long term outcomes using tax data we find that moving to a lower poverty neighborhood when young before age 13 increases college attendance and earnings and reduces single parenthood rates moving as an adolescent has slightly negative impacts perhaps because of disruption effects the decline in the gains from moving with the age when children move suggests that the duration of exposure to better environments during childhood is an important determinant of children s long term outcomes jel i31 i38 j13 r23 r38

how does your kindergarten classroom affect your earnings evidence from project star in project star 11 571 students in tennessee and their teachers were randomly assigned to classrooms within their schools from kindergarten to third grade this article evaluates the long term impacts of star by linking the experimental data to administrative records we first demonstrate that kindergarten test scores are highly correlated with outcomes such as earnings at age 27 college attendance home ownership and retirement savings we then document four sets of experimental impacts first students in small classes are significantly more likely to attend college and exhibit improvements on other outcomes class size does not have a significant effect on earnings at age 27 but this effect is imprecisely estimated second students who had a more experienced teacher in kindergarten have higher earnings third an analysis of variance reveals significant classroom effects on earnings students who were randomly assigned to higher quality classrooms in grades k 3 as measured by classmates end of class test scores have higher earnings college attendance rates and other outcomes finally the effects of class quality fade out on test scores in later grades but gains in noncognitive measures persist

sequential bargaining with correlated values the paper analyzes an infinite horizon sequential bargaining game with one sided offers between a buyer and a seller when the buyer s valuation depends on the seller s the seller knows the value of the object and the buyer does not the influence of relative discount factors on the solution is studied it is shown for example that an impasse may result if the buyer offeror is too impatient relative to the seller the buyer makes a single take it or leave it offer

optimal experimentation in a changing environment this paper studies optimal experimentation by a monopolist who faces an unknown demand curve subject to random changes and who maximizes profits over an infinite horizon in continuous time we show that there are two qualitatively very different regimes determined by the discount rate and the intensities of demand curve switching and the dependence of the optimal policy on these parameters is discontinuous one regime is characterized by extreme experimentation and good tracking of the prevailing demand curve the other by moderate experimentation and poor tracking moreover in the latter regime the agent eventually becomes trapped into taking actions in a strict subset of the feasible set

does the market value value added evidence from housing prices after a public release of school and teacher value added value added data are an increasingly common evaluation tool for schools and teachers many school districts have adopted these methods and released the results publicly in this paper we study the release of value added data in los angeles by the los angeles times newspaper to identify how measured value added is capitalized into housing prices this analysis is the first in the us school valuation literature to examine property value responses to a value added information shock which is of interest as this measure is less correlated with demographics than typical school quality measures unique to this setting as well is the release of both school and teacher level value added data which allows us to examine how property values respond to both types of information using a difference indifferences methodology surrounding the release we find that neither school nor teacher value added scores are capitalized into home prices our results suggest that despite the contentiousness following these data releases homeowners do not consider value added models as currently constructed to be a relevant school quality measure on the margin

search with adverse selection this paper analyzes a sequential search model with adverse selection we study information aggregation by the price how close the equilibrium prices are to the full information prices when search frictions are small we identify circumstances under which prices fail to aggregate information well even when search frictions are small we trace this to a strong form of the winner s curse that is present in the sequential search model the failure of information aggregation may result in inefficient allocations

bargaining with common values this paper examines a bargaining model with asymmetric information in which the private valuations of the two bargaining agents are correlated it shows that equilibria in such models typically exhibit a significant probability of a significant delay to agreement the paper characterizes the unique perfect bayesian equilibrium to the game in which an uninformed buyer makes offers to a privately informed seller it also shows by example that in this framework bargainers may rationally break off negotiations even in the presence of commonly known gains from trade

interregional migration and interindustry labour mobility in canada a simultaneous approach this paper argues that interindustry labour mobility and interregional migration are simultaneously determined processes it estimates a bivariate probit model of migration and mobility using data for canada and concludes that the interindustry mobility of labour is dominated by the availability of employment hours and that wage differentials are a statistically significant but small determinant of interregional migration since interindustry mobility is much larger in magnitude than interregional migration quantity constraints in labour markets are of central importance to the adaptive capacity of the economy summary in fre excerpt

generalizations about using value added measures of teacher quality the extensive investigation of the contribution of teachers to student achievement produces two generally accepted results first there is sub stantial variation in teacher quality as measured by the value added to achievement or future aca demic attainment or earnings second variables often used to determine entry into the profession and salaries including post graduate schooling experience and licensing examination scores appear to explain little of the variation in teacher quality so measured with the exception of early experience together these findings underscore explicitly that observed teacher characteristics do not represent teacher quality

revenue management without commitment dynamic pricing and periodic flash sales a seller has a fixed number of goods to sell by a deadline at each time he posts a regular price and decides whether to hold a flash sale over time buyers privately enter the market and strategically time their purchases if a buyer does not purchase when she arrives she can pay an attention cost to recheck the regular price afterwards or she can wait for future flash sales where she may obtain a good at a discounted price in the unique markov perfect equilibrium the seller sporadically holds flash sales to lower the stock of goods a flash sale increases the willingness to pay of future buyers but decreases the willingness to pay of buyers who arrive early in the game when it is very likely that a buyer will obtain a good in a flash sale the seller holds a big initial flash sale for all but one unit of the good

market integration between developing countries and urban unemployment the perspective of the real minimum wage this article examines the effect of market integration through free trade and factor mobility on the urban unemployment rate of a developing country whose economy is large enough to influence the terms of trade from the perspective of the real minimum wage it is shown that free trade would result in a rise or a decline in the country s urban unemployment rate depending on its trade pattern while the effect of labour mobility on a country s urban unemployment rate is determined by the difference between the ratio of would be farmers to incoming workers and that of farm leavers to outgoing workers the result of capital mobility will depend on a comparison of the initial urban unemployment rates of two countries

brain drain from turkey an investigation of students return intentions the emigration of skilled individuals from turkey attracted greater media attention and the interest of policymakers in turkey particularly after the experience of recurrent economic crises that have led to an increase in unemployment among the highly educated young this study estimates a model of return intentions using a data set compiled from an internet survey of turkish students residing abroad the findings of this study indicate that as expected higher salaries offered in the host country and lifestyle preferences including a more organized environment in the host country increase the probability of student nonreturn however the analysis also points to the importance of prior return intentions and the role of the family in the decision to return to turkey or stay overseas it is also found that the compulsory service requirement attached to government scholarships increases the probability of student return turkish student association membership also increases return intentions longer sta

the home selling problem theory and evidence this paper formulates and solves the problem of a homeowner who wants to sell their house for the maximum possible price net of transactions costs including real estate commissions the optimal selling strategy consists of an initial list price with subs equent weekly decisions on how much to adjust the list price until the home is sold or withdrawn from the market the solution also yields a sequence of reservation prices that determine whether the homeowner should accept bids from potential buyers who arrive stochastically over time with an expected arrival rate that is a decreasing function of the list price this model was developed to provide a theoretical explanation for list price dynamics and bargaining behavior observed for a sample of homeowners in england in a new data set introduced by
