the dutch disease effects on tourism the case of australia industries in an economy are inter dependent on each other however the relationship among them is not always positive the recent mining boom in australia has adversely affected many other non mining related industries including tourism through the effects of resource constraints and a strong appreciation of the exchange rate this paper examines in detail the mining boom effects on tourism in specific markets such as those for inter state intra state and inbound tourism through the movement of price indexes of each market across states and territories in australia furthermore while negative impacts on tourism are consistent with the traditional dutch disease theory this paper also highlights an important point to policy makers that strategic planning for investment in accommodation and aviation can have positive impacts on tourism during and after the boom has passed

on the demographic composition of colleges and universities in market equilibrium achieving diversity in the racial and ethnic makeup of the student body is one of the objectives that a college pursues in making decisions about admission and financial aid there has been a tremendous amount of debate about policies that colleges should adopt or be proscribed from adopting with respect to diversity rather than join this largely normative debate we adopt a positive focus investigating how colleges quests for ethnic and racial diversity affect admission and financial aid policies the college quality hierarchy and the distribution of whites and nonwhite students across colleges of differing qualities we provide a theoretical framework for investigating the effects of preferences for diversity augmented with results from a parallel computational model calibrated to u s data the effects of efforts to achieve diversity in colleges depend not only on the weight that colleges give to diversity but also on the value that prospective students place on diversity diversity may be of concern to no one only to colleges to both colleges and students or to colleges and a subset of students we first describe a baseline model without preferences for diversity and then examine three alternatives in which preferences for racial diversity are present

bitcoin for energy commodities before and after the december 2013 crash diversifier hedge or safe haven abstractwe study the relationship between bitcoin and commodities by assessing the ability of bitcoin to act as a diversifier hedge or safe haven against daily movements in commodities in general and energy commodities in particular we focus on energy commodities because energy in the form of electricity is an essential input in the bitcoin production for the entire period results show that bitcoin is a strong hedge and a safe haven against movements in both commodity indices we further examine whether that ability is also present for non energy commodities and our analysis show insignificant results when energy commodities are excluded from the general commodity index we also account for the december 2013 bitcoin price crash and our results reveal that bitcoin hedge and safe haven properties against commodities and energy commodities are only present in the pre crash period whereas in the post crash period bitcoin is no more than a diversifier in addition to uncovering the time varying role o

building criminal capital behind bars peer effects in juvenile corrections this paper analyzes the influence that juvenile offenders serving time in the same correctional facility have on each other s subsequent criminal behavior the analysis is based on data on over 8 000 individuals serving time in 169 juvenile correctional facilities during a two year period in florida these data provide a complete record of past crimes facility assignments and arrests and adjudications in the year following release for each individual to control for the non random assignment to facilities we include facility fixed effects thereby estimating peer effects using only within facility variation over time we find strong evidence of peer effects for various categories of theft burglary and felony drug and weapon crimes the influence of peers primarily affects individuals who already have some experience in a particular crime category we also find evidence that peer effects are stronger in smaller facilities and that the predominant types of peer effects differ in residential versus non residential facilities effects in the latter are consistent with network formation among youth serving time close to home

labor market returns to college major specificity abstract this paper develops a new approach to measuring human capital specificity in the context of college majors and estimates its labor market return over a worker s life cycle to measure specificity we propose a novel method grounded in human capital theory a gini coefficient of earnings premia for a major across occupations our measure captures the notion of skill transferability across jobs education and nursing are the most specific majors while philosophy and psychology are among the most general using data from the american community survey we find that the most specific majors typically pay off the most with an early career earnings premium of about 5 6 over average majors 15 20 over the most general majors driven by higher hourly wages general majors lag far behind at every age despite their earnings advantage graduates from specific majors are the least likely to hold managerial positions with graduates from majors of average specificity being the most likely to do so it may be that managerial positions require a mix of specific knowledge and broadly applicable skills

an empirical analysis of competitive nonlinear pricing abstract we estimate a model of competitive nonlinear pricing with multidimensional preference heterogeneity using individual level data on advertisements bought by local businesses e g doctors electricians from two yellow page directories in one u s city market variation in individual choices and payments allows us to identify the joint density of preferences marginal costs of publishing and common utility parameters our estimates suggest substantial welfare loss due to asymmetric information comparing duopoly outcomes with counterfactual monopoly outcomes we find that with less competition i producer surplus increases substantially ii more low type consumers are excluded iii product variety increases but benefits accrue only to the high type consumers iv total consumer surplus decreases v but its distribution across consumers does not change

peer effects in medical school abstract using data on the universe of students who graduated from us medical schools between 1996 and 1998 we examine whether the abilities and specialty preferences of a medical school class affect a student s academic achievement in medical school and his choice of specialty we mitigate the selection problem by including school specific fixed effects and show that this method yields an upper bound on peer effects for our data we estimate positive peer effects that disappear when school specific fixed effects are added to control for the endogeneity of a peer group we find no evidence that peer effects are stronger for blacks that peer groups are formed along racial lines or that students with relatively low ability benefit more from their peers than students with relatively high ability however we do find some evidence that peer groups form along gender lines

effort and comparison income experimental and survey evidence the authors test the hypothesis that individual effort on the job depends both on one s own income and on the individual s position in the relevant income distribution combining experimental evidence from a gift exchange game with multi country issp survey data they analyze the extent to which relative income affects an individual s effort finding that an individual s rank in the income distribution more strongly determines effort than does others average income which suggests that comparisons are more ordinal than cardinal their experiment also reveals that comparisons over time affect effort individuals who received higher income offers or enjoyed higher income rank in the past exerted lower levels of effort for a given current income and rank

a general equilibrium analysis of state and private colleges and access to higher education in the u s abstract we develop a general equilibrium model of the market for undergraduate higher education that captures the coexistence of public and private colleges the large degree of quality differentiation among them and the tuition and admission policies that emerge from their competition for students a quantitative version of the model matches well estimates of enrollment elasticities variation in need based and merit based institutional aid with respectively student income and ability and aggregate characteristics of u s higher education including college attendance in public and private schools tuition levels and the provision of federal aid predictions about the provision of federal aid and the distribution of students across colleges by ability and income match the empirical counterparts well we use the model to examine the consequences of federal and state aid policies a one third increase in the maximum federal aid increases college attendance by 6 of the initial college population most of the increase being in state colleges and mainly of poor students elite private colleges reduce institutional aid and use the net funding gain to spend more on educational inputs and to substitute some highly able poor students for less able rich students reductions in federal or state aid result in substantially reduced attendance mainly by poor students reductions of support to state colleges induce private colleges to increase enrollments modestly and improve in quality as demand shifts toward them

the inefficiency of bitcoin bitcoin has received much attention in the media and by investors in recent years although there remains scepticism and a lack of understanding of this cryptocurrency we add to the literature on bitcoin by studying the market efficiency of bitcoin through a battery of robust tests evidence reveals that returns are significantly inefficient over our full sample but when we split our sample into two subsample periods we find that some tests indicate that bitcoin is efficient in the latter period therefore we conclude that bitcoin in an inefficient market but may be in the process of moving towards an efficient market

momentum trading in cryptocurrencies short term returns and diversification benefits abstract we test for the presence of momentum effects in cryptocurrency market and estimate dynamic conditional correlations dccs of returns between momentum portfolios of cryptocurrencies and traditional assets first investment portfolios are constructed adherent to the classic j k momentum strategy using daily data from twelve cryptocurrencies for over a period of three years we identify the existence of momentum effect which is highly significant for short term portfolios but disappears over the longer term second we show that cross correlations of weekly returns between momentum portfolio of cryptocurrencies and traditional assets are unlike correlations of returns between traditional assets third we find that momentum portfolios of cryptocurrencies not only offer diversification benefits but also can be a hedge and safe haven for traditional assets

private school vouchers and student achievement an evaluation of the milwaukee parental choice program in 1990 wisconsin began providing vouchers to a small number of low income students to attend nonsectarian private schools controlling for individual fixed effects i compare the test scores of students selected to attend a participating private school with those of unsuccessful applicants and other students from the milwaukee public schools i find that students in the milwaukee parental choice program had faster math score gains than but similar reading score gains to the comparison groups the results appear robust to data imputations and sample attrition although these deficiencies of the data should be kept in mind when interpreting the results

on the inefficiency of bitcoin abstract urquhart 2016 investigated the market efficiency of bitcoin by means of five different tests on bitcoin returns it was concluded that the bitcoin returns do not satisfy the efficient market hypothesis we show here that a simple power transformation of the bitcoin returns do satisfy the hypothesis through the use of eight different tests the transformation used does not lead to any loss of information

subsidies hierarchy and peers the awkward economics of higher education higher education is a business it produces and sells educational services to customers for a price and it buys inputs with which to make that product production is subject to technological constraints costs and revenues discipline decisions and determine the long run viability of a college or university but higher education is not just a business while that statement is often meant to imply that higher education is nobler than business more decent and humane in the purposes it serves it can also mean that even in economic terms higher education is in important ways simply different from a business this paper asks how well our extensive experience with commercial businesses and the microeconomic theory of firms and markets that has evolved to describe them helps in understanding the economics of higher education that experience and those insights will be used by trustees politicians administrators lawyers reporters and the public as well as by economists to understand and evaluate the behavior of colleges and universities so it is useful to ask how safe it is to use the economic analogy in the context of higher education drawing parallels between universities and firms students and customers faculty and labor markets and so on the discussion here seeks to identify the key economic features of higher education that make it different from familiar for profit industries and to ask what difference those differences make this is a stick that can be picked up from either end one approach is to start with meticulous economic theory and see how far it can be made to encompass the economic realities of higher education an excellent recent paper by rothschild and white 1995 does that in their matching model students and colleges meet

identification of endogenous social effects the reflection problem this paper examines the reflection problem that arises when a researcher observing the distribution of behaviour in a population tries to infer whether the average behaviour in some group influences the behaviour of the individuals that comprise the group it is found that inference is not possible unless the researcher has prior information specifying the compisition of reference groups if this information is available the prospects for inference depend critically on the population relationship between the variables defining reference groups and those directly affecting outcomes inference is difficult to implossible if these variables are functionally dependent or are statistically independent the prospects are better if the variables defining reference groups and those directly affecting outcomes are moderately related in the population

cryptocurrencies and momentum abstract retrieving a set of 143 cryptocurrencies for a sample spanning 2014 2018 we investigate the popular momentum strategy implemented in the cryptocurrency market contrary to earlier studies our findings do not indicate any evidence of significant momentum payoffs supporting the view that the cryptocurrency market is far more efficient than suggested in earlier studies

career choice and wage growth in this article i present structural estimates of a search model that flexibly incorporates general human capital accumulation along with career and firm choice where a career is empirically identified as a combination of industry and occupation i use these estimates to empirically distinguish between the relative importance of various factors for generating wage growth over the life cycle evidence presented in the article highlights the importance of considering the two stage search process that originates from the model in particular i demonstrate that previous instrumental variables methods dramatically underestimate the importance of firm specific matches for wage growth

the demand for and return to education when education outcomes are uncertain this article treats education as a sequential choice that is made under uncertainty a simple model is used to explore the effects of ability high school preparation preferences for schooling the borrowing rate and ex post payoffs to college on the probability of various post secondary college outcomes and the ex ante return to starting college the model motivates an empirical method of accounting for uncertainty about educational outcomes and for nonlinearity in the relationship between years of education and earnings when estimating the expected return to the first year of college

immigration and inequality immigration is often viewed as a proximate cause of the rising wage gap between highand low skilled workers nevertheless there is controversy over the appropriate theoretical and empirical framework for measuring the presumed effect and over the precise magnitudes involved this paper offers an overview and synthesis of existing knowledge on the relationship between immigration and inequality focusing on evidence from cross city comparisons in the u s while some researchers have claimed that a cross city research design is inherently flawed i argue that the evidence from cross city comparisons is remarkably consistent with recent findings based on aggregate time series data in particular cross city and aggregate time series comparisons provide support for three key conclusions 1 workers with below high school education are perfect substitutes for those with a high school education 2 high school equivalent and college equivalent workers are imperfect substitutes with an elasticity of substitution on the order of 2 3 within education groups immigrants and natives are imperfect substitutes together these results imply that the average impacts of recent immigrant inflows on the relative wages of u s natives are small the effects on overall wage inequality including natives and immigrants are larger reflecting the concentration of immigrants in the tails of the skill distribution and higher residual inequality among immigrants than natives even so immigration accounts for a small share 5 of the increase in u s wage inequality between 1980 and 2000

field of study earnings and self selection why do individuals choose different types of post secondary education and what are the labor market consequences of those choices we show that answering these questions is difficult because individuals choose between several unordered alternatives even with a valid instrument for every type of education instrumental variables estimation of the payoffs require information about individuals ranking of education types or strong additional assumptions like constant effects or restrictive preferences these identification results motivate and guide our empirical analysis of the choice of and payoff to field of study our context is norway s post secondary education system where a centralized admission process covers almost all universities and colleges this process creates credible instruments from discontinuities which effectively randomize applicants near unpredictable admission cutoffs into different fields of study at the same time it provides us with strategy proof measures of individuals ranking of fields taken together this allows us to estimate the payoffs to different fields while correcting for selection bias and keeping the next best alternatives as measured at the time of application fixed we find that different fields have widely different payoffs even after accounting for institutional differences and quality of peer groups for many fields the payoffs rival the college wage premiums suggesting the choice of field is potentially as important as the decision to enroll in college the estimated payoffs are consistent with individuals choosing fields in which they have comparative advantage we also test and reject assumptions of constant effects or restrictive preferences suggesting that information on next best alternatives is essential to identify payoffs to field of study

the determinants of chinese visitors to australia a dynamic demand analysis although china has progressively become an important inbound tourism market for australia its demand elasticities have been little studied to date this study examines the determinants of chinese visitors to australia using a dynamic time series estimator interesting findings include a high income elasticity as a source of the continuous doubledigit growth rates in chinese arrivals that australia has experienced over the past two decades together with relatively high total trip price elasticities for both short run and long run a trend of chinese outbound to australia is also identified from a policy perspective the results confirm that keeping a low cost of visiting australia both ground and travel costs is a good strategy to secure greater numbers of chinese tourists

decentralized college admissions we study decentralized college admissions with uncertain student preferences colleges strategically admit students likely to be overlooked by competitors highly ranked students may receive fewer admissions or have a higher chance of receiving no admissions than those ranked below when students attributes are multidimensional colleges avoid head on competition by placing excessive weight on school specific attributes such as essays restricting the number of applications or wait listing alleviates enrollment uncertainty but the outcomes are inefficient and unfair a centralized matching via gale and shapley s deferred acceptance algorithm attains efficiency and fairness but may make some colleges worse off than under decentralized matching

affirmative action in higher education how do admission and financial aid rules affect future earnings this paper addresses how changing the admission and financial aid rules at colleges affects future earnings i estimate a structural model of the following decisions by individuals where to submit applications which school to attend and what field to study the model also includes decisions by schools as to which students to accept and how much financial aid to offer simulating how black educational choices would change were they to face the white admission and aid rules shows that race based advantages had little effect on earnings however removing race based advantages does affect black educational outcomes in particular removing advantages in admissions substantially decreases the number of black students at top tier schools while removing advantages in financial aid causes a decrease in the number of blacks who attend college

early decision and financial aid competition among need blind colleges and universities abstract this paper presents a stylized theoretical model of competition among need blind colleges and universities that implement early decision admissions under need blind admissions an applicant s financial aid status cannot affect their likelihood of admission in the model a need blind school can use early decision admissions as a screening mechanism to indirectly identify a student s ability to pay while superficially maintaining a need blind policy as a result in equilibrium non financial aid students are more likely to be admitted than financial aid students of comparable quality

inefficiencies from metropolitan political and fiscal decentralization failures of tiebout competition we examine the welfare effects of provision of local public goods in an empirically relevant setting using a multi community model with mobile and heterogeneous households and with flexible housing supplies we characterize the first best allocation and show efficiency can be implemented with decentralization using head taxes we calibrate the model and compare welfare in property tax equilibria both decentralized and centralized to the efficient allocation inefficiencies with decentralization and property taxation are large dissipating most if not all the potential welfare gains that efficient decentralization could achieve in property tax equilibrium centralization is frequently more efficient an externality in community choice underlies the failure to achieve efficiency with decentralization and property taxes poorer households crowd richer communities and free ride by consuming relatively little housing thereby avoiding taxes copyright oxford university press

optimal vs naive diversification in cryptocurrencies abstract this paper contributes to the literature on cryptocurrencies by examining the performance of naive 1 n and optimal markowitz diversification in a portfolio of four popular cryptocurrencies we employ weekly data with weekly rebalancing and show there is very little to select between naive diversification and optimal diversification our results hold for different levels of risk aversion and an alternative estimation window

the inefficiency of bitcoin revisited a dynamic approach abstract this letter revisits the informational efficiency of the bitcoin market in particular we analyze the time varying behavior of long memory of returns on bitcoin and volatility 2011 until 2017 using the hurst exponent our results are twofold first r s method is prone to detect long memory whereas dfa method can discriminate more precisely variations in informational efficiency across time second daily returns exhibit persistent behavior in the first half of the period under study whereas its behavior is more informational efficient since 2014 finally price volatility measured as the logarithmic difference between intraday high and low prices exhibits long memory during all the period this reflects a different underlying dynamic process generating the prices and volatility

cashier or consultant entry labor market conditions field of study and career success we measure impacts of entry conditions on labor market outcomes for the us college graduating classes of 1974 2011 a large recession reduces initial earnings by 10 through full time work and wag

college major choice to college then major choice many countries use college major specific admissions policies that require a student to choose a college major pair jointly given the potential of student major mismatches we explore the equilibrium effects of postponing student choice of major we develop a sorting equilibrium model under the college major specific admissions regime allowing for match uncertainty and peer effects we estimate the model using chilean data we introduce the counterfactual regime as a stackelberg game in which a social planner chooses college specific admissions policies and students make enrollment decisions learn about their fits to various majors before choosing one our estimates indicate that switching from the baseline to the counterfactual regime leads to a 1 increase in average student welfare and that it is more likely to benefit female low income and or low ability students

the impact of student debt on education career and marriage choices of female lawyers abstract we develop and estimate a dynamic model to study the impact of student debt on education career and marriage market choices of young female lawyers our model accounts for several important institutional features of the labor market for lawyers including differences in the work hours across occupational tracks and learning about the prospects of promotion to partner some female students need to take on large amounts of student debt to finance their education and hence start their careers with large amounts of negative wealth the empirical findings suggest that student debt has negative effects on marriage prospects career prospects and investments in educational quality of female lawyers the analysis also provides new insights into the design of public policies that aim to increase public sector employment we show that it is possible to design conditional wage or debt service subsidy programs that significantly increase public sector career choices at reasonable costs

ability tracking school competition and the distribution of educational benefits abstract to study the effects of ability grouping on school competition we develop a theoretical and computational model of tracking in public and private schools we examine tracking s consequences for the allocation of students of differing abilities and income within and between public and private schools private schools tend to attract the most able and wealthiest students and rarely track in equilibrium public sector schools can maximize attendance by tracking students public schools retain a greater proportion of higher ability students by tracking but lose more wealthy lower ability students to the private sector consequently socioeconomic status is a predictor of track assignment in public schools for the entire population public sector tracking has small aggregate effects on achievement and welfare but results in significant redistribution from lower to higher ability students

mobility targeting and private school vouchers simulations are derived from a three district model of low middle and highincome school districts calibrated to new york data with housing stocks that vary within and across districts in this model it is demonstrated that school district targeted vouchers are similar in their impact to nontargeted vouchers but vastly different from vouchers targeted to low income households furthermore strong migration effects are shown to significantly improve the likely equity consequences of voucher programs jel 122 128 h73 persistent frustration with the perceived low quality of public education exacerbated by concerns over the inherently unequal levels of public school quality across school districts has caused policy makers courts and researchers to investigate modifications and alternatives to the current public school system one idea that has received increasing academic and public attention is that of private school vouchers with proponents arguing that the competitive pressures of voucher programs would cause improvements in the efficiency of the publicschool system while at the same time addressing equity concerns if vouchers can be targeted to low income households or low income school districts but aside from a few limited experiments in some u s cities our experience with vouchers in the united states remains virtually nonexistent this limits the amount of information researchers can derive from standard empirical analysis in that it forces them to rely on only current nonvoucher induced differences in competition despite important suggestive results such work may not anticipate all the impacts from a large scale policy such as the voucher policies currently under discussion at the same time theoretical models of school finance are also limited in that they often either focus on only one particular aspect of the general equilibrium school finance problem or they are too rich and complex to yield crisp predictions

limit theorems for estimating the parameters of differentiated product demand systems we provide an asymptotic distribution theory for a class of generalized method of moments estimators that arise in the study of dierentiated product markets when the number of observations is associated with the number of products within a given market we allow for three sources of error sampling error in estimating market shares simulation error in approximating the shares predicted by the model and the underlying model error it is shown that the estimators are can provided the size of the consumer sample and the number of simulation draws grow at a large enough rate relative to the number of products we consider the implications of the results for berry levinsohn and pakes 1995 random coecient logit model and the pure characteristic model analyzed in berry and pakes 2002 the required rates dier for these two frequently used demand models a small monte carlo study shows that the dierence in asymptotic properties of the two models are reflected in quite a striking way in the models small sample properties moreover the limit distributions provide a good approximation to the actual monte carlo distribution of the parameter estimates the results have important implications for the computational burden of the two models

new evidence on the economic determinants of postsecondary schooling choices the effects of tuition costs financial aid and individual attributes on college choice are analyzed using a conditional logit model the results confirm that financial aid can be an important determinant of postsecondary school attendance and that individual academic ability relative to the academic standards of a college is an important determinant of which of available college alternatives is chosen

nonparametric engel curves and revealed preference this paper applies revealed preference theory to the nonparametric statistical analysis of consumer demand knowledge of expansion paths is shown to improve the power of nonparametric tests of revealed preference the tightest bounds on indifference surfaces and welfare measures are derived using an algorithm for which revealed preference conditions are shown to guarantee convergence nonparametric engel curves are used to estimate expansion paths and provide a stochastic structure within which to examine the consistency of household level data and revealed preference theory an application is made to a long time series of repeated cross sections from the family expenditure survey for britain the consistency of these data with revealed preference theory is examined for periods of consistency with revealed preference tight bounds are placed on true cost of living indices

the specificity of general human capital evidence from college major choice college graduates do not always pursue careers related to their major science majors working in jobs unrelated to their field of study earn approximately 30 lower wages than those working in related jobs we develop a structural model of major choice and labor market outcomes that allows for skill uncertainty and differential accumulation of human capital across major our findings confirm that the average return to obtaining a science degree and working in a related job remains close to 30 we also find that individuals are uncertain about their future productivity at the time of the college major decision

the econometrics of nonlinear budget sets traditional empirical analysis of consumer demand has usually made the assumption of linear budget sets that is the consumer is assumed to purchase any desired quantity at a constant price subject to a budget constraint the major exception to this framework is the analysis of demand when some goods are rationed 2 in the rationed case the price is constant up to a quantity limit in contrast to the rationed case here i consider the situation where the price varies with the amount of the good purchased empirical situations with nonconstant prices come readily to mind and of course they have received much recent attention from theorists since mirrlees 44 paper on optimal nonlinear taxation the following examples are meant to give a partial listing of cases when nonlinear budget sets occur i electricity prices many electric utilities engage in declining block pricing that is the marginal price of successive kwh s of electricity decrease at a given number of points determined by total demand thus the budget set is piecewise linear houthakker 36 was the first to propose an approach to this problem taylor 51 analyzes the problem at length and hausman kinnucin and mcfadden 31 use an instrumental variables estimator to provide consistent estimates of the demand function

student portfolios and the college admissions problem we develop a decentralized bayesian model of college admissions with two ranked colleges heterogeneous students and two realistic match frictions students find it costly to apply to college and college evaluations of their applications are uncertain students thus face a portfolio choice problem in their application decision while colleges choose admissions standards that act like market clearing prices enrollment at each college is affected by the standards at the other college through student portfolio reallocation in equilibrium student college sorting may fail weaker students sometimes apply more aggressively and the weaker college might impose higher standards applying our framework we analyse affirmative action showing how it induces minority applicants to construct their application portfolios as if they were majority students of higher caliber

decentralization in replicated club economies with multiple private goods abstract we show that exhaustion of blocking opportunities is a sufficient condition such that every allocation in the core of a replicated club economy can be decentralized as a competitive equilibrium and that a related condition efficient scale is necessary and under an assumption on endowments sufficient such that competitive equilibrium exists and the core is nonempty these results do not require the euclidean structure and monotonicity assumed in lindahl equilibrium do not require convexity of preferences or costs and do not require the strong assumption that private goods are essential journal of economic literature classification numbers d46 d50 d61 h40

clubs and the market this paper defines a general equilibrium model with exchange and club formation agents trade multiple private goods widely in the market can belong to several clubs and care about the characteristics of the other members of their clubs the space of agents is a continuum but clubs are finite it is shown that i competitive equilibria exist and ii the core coincides with the set of equilibrium states the central subtlety is in modeling club memberships and expressing the notion that membership choices are consistent across the population

the analytics of the pricing of higher education and other services in which the customers are inputs many services provide outputs that depend partially on the customers as inputs the presence of other customers often contributes to the output experienced by each purchaser higher education is the premier example others are legion we provide a simple model that addresses the questions of competitive pricing and allocative efficiency for these types of services prices that charge customers for what they get on net output minus input from the firm both are competitive and support efficient allocations these prices internalize the apparent external effects of customers on each other few examples of such prices exist in the real world

speculative bubbles in bitcoin markets an empirical investigation into the fundamental value of bitcoin amid its rapidly increasing usage and immense public interest the subject of bitcoin has raised profound economic and societal issues in this paper we undertake economic and econometric modelling of bitcoin prices as with many asset classes we show that bitcoin exhibits speculative bubbles further we find empirical evidence that the fundamental price of bitcoin is zero

does competition among public schools benefit students and taxpayers tiebout choice among districts is the most powerful market force in american public education naive estimates of its effects are biased by endogenous district formation i derive instruments from the natural boundaries in a metropolitan area my results suggest that metropolitan areas with greater tiebout choice have more productive public schools and less private schooling little of the effect of tiebout choice works through its effect on household sorting this finding may be explained by another finding students are equally segregated by school in metropolitan areas with greater and lesser degrees of tiebout choice among districts

educational vouchers when there are peer group effects size matters in this article i study the effects various educational voucher policies have on the sorting of children across schools and the per student expenditure levels at these schools when a child s peer group matters and students differ over income and ability i find that depending on the magnitude of the voucher switching from a public system to a voucher system could entail either welfare gains or losses all voucher policies under consideration lead to greater inequality than the public system however these increases are not monotone in the voucher size several states are considering enacting or have enacted educational voucher plans which entail giving parents money to send their children to private schools both the cities of milwaukee and cleveland have started educational voucher programs during the 1996 1997 school year around 1650 students in milwaukee received vouchers worth 4400 at a total cost of over 7 million in the same year cleveland spent 6 4 million distributing an average voucher of around 2000 to 1996 students other smaller scale voucher plans have sprouted up in school districts around the country proponents claim vouchers give poor parents educational choice for their children and give poor children a chance to succeed where the public schools fail them opponents argue that by funding vouchers resources will be funneled out of the public schools to a small number of students and that the majority of students who are left behind in the public schools will suffer in order to evaluate these proposals a framework is needed that incorporates the factors important to educational outcomes along with family background and educational expenditure many empirical studies have shown that the peer group plays a significant role in educational achievement consider a change in educational policy for example adopting a voucher system such a switch will affect not only

crime and social interactions the high variance of crime rates across time and space is one of the oldest puzzles in the social sciences this variance appears too high to be explained by changes in the exogenous costs and benefits of crime we present a model where social interactions create enough covariance across individuals to explain the high cross city variance of crime rates this model provides an index of social interactions which suggests that the amount of social interactions is highest in petty crimes moderate in more serious crimes and almost negligible in murder and rape

a dynamic analysis of educational attainment occupational choices and job search this article examines career choices using a dynamic structural model that nests a job search model within a human capital model of occupational and educational choices wage growth occurs in the model because workers move between firms and occupations as they search for suitable job matches and because workers endogenously accumulate firm and occupation specific human capital simulations performed using the estimated model reveal that both self selection in occupational choices and mobility between firms account for a much larger share of total earnings and utility than the combined effects of firm and occupation specific human capital

antitrust and higher education was there a conspiracy to restrict financial aid in 1991 the u s justice department s antitrust division accused mit and the ivy league schools of fixing prices the schools claimed that their cooperative behavior enabled them to concentrate financial aid on needy students and did not affect price we analyze the empirical determinants of tuition and find no evidence that the schools agreement raised price we also analyze the appropriate application of the antitrust laws to nonprofit institutions and conclude that in the absence of adverse price or output effects the justification for the collective action should be considered under the rule of reason

measuring market power in the ready to eat cereal industry the ready to eat cereal industry is characterized by high concentration high price cost margins large advertising to sales ratios and numerous introductions of new products previous researchers have concluded that the ready to eat cereal industry is a classic example of an industry with nearly collusive pricing behavior and intense nonprice competition this paper empirically examines this conclusion in particular i estimate price cost margins but more importantly i am able empirically to separate these margins into three sources i that which is due to product differentiation ii that which is due to multi product firm pricing and iii that due to potential price collusion the results suggest that given the demand for different brands of cereal the first two effects explain most of the observed price cost margins i conclude that prices in the industry are consistent with noncollusive pricing behavior despite the high price cost margins leading firms are able to maintain a portfolio of differentiated products and influence the perceived product quality it is these two factors that lead to high price cost margins

discrete choice with social interactions this paper provides an analysis of aggregate behavioural outcomes when individual utility exhibits social interaction effects we study generalized logistic models of individual choice which incorporate terms reflecting the desire of individuals to conform to the behaviour of others in an environment of noncooperative decisionmaking laws of large numbers are generated in such environments multiplicity of equilibria in these models which are equivalent to the existence of multiple self consistent means for average choice behaviour will exist when the social interactions exceed a particular threshold local stability of these multiple equilibria is also studied the properties of the noncooperative economy are contrasted with the properties of an economy in which a social planner determines the set of individual choices finally a likelihood function based on the theoretical model is given and conditions for the econometric identifiability of the model are established

do peers influence occupational preferences evidence from randomly assigned peer groups at west point abstract there is substantial variation across occupations in outcomes such as earnings job satisfaction and health yet little is known about how occupational preferences are shaped and evolve this paper assesses a channel that may influence occupational preferences peer effects by exploiting unique institutional features and a natural experiment at west point to document the way students i e cadets occupational preferences evolve and to test for peer effects after graduation cadets must enter the u s army as an officer in one of 16 occupational branches and are required to rank order their preferences for the branches repeatedly over four years west point randomly assigns cadets to social groups both at broad company and narrow roommate levels we leverage the timing of the randomization and preference elicitations to test for peer effects at the company roommate and older peer levels with the possible exception of the first few weeks of exposure we find little evidence of peer effects we also use a survey of cadets to explore mechanisms and find evidence that peer information may not be credible in this case but rather cadets rely on mentors and job characteristics when making this decision

equilibrium and inefficiency in a community model with peer group effects public service output depends on input expenditures on own personal characteristics and on the characteristics of the other residents in the community the peer group effect in a community model with public expenditures set by voting with migration between communities and with land price differentials capitalization it is shown that communities may become heterogeneous in composition and second best inefficient this equilibrium occurs when the peer group effect is neither too strong nor too weak the inefficiency arises because an externality is created by migration the land price differential does not play the part of the price of the better peer group but of a transfer payment

optimal financial aid policies for a selective university our paper provides a model of optimal financial aid policies for a selective university the model implies that the financial aid package to be offered to each category of admitted applicants depends on the elasticity of the fraction who accept offers of admission with respect to the financial aid package offered them the propensity of the category to enroll the elasticity of the category s average quality with respect to the number admitted and the relative weight the university assigns them in the utility function while the latter must be determined subjectively the former parameters are subject to empirical estimation we conclude with a study of one institution s data and illustrate how they may be estimated these estimates are then applied to illustrate what the optimal financial aid policy would be for the university

market power and price discrimination in the u s market for higher education the main purpose of this paper is to estimate an equilibrium model of private and public school competition that can generate realistic pricing patterns for private universities in the u s we show that the parameters of the model are identified and can be estimated using a semi parametric estimator given data from the npsas we find substantial price discrimination within colleges we estimate that a 10 000 increase in family income increases tuition at private schools by on average 210 to 510 a one standard deviation increase in ability decreases tuition by approximately 920 to 1 960 depending on the selectivity of the college discounts for minority students range between 110 and 5 750

multi dimensional skills specialization and oligopolistic competition in higher education abstract this paper develops a differentiated products model of school competition that distinguishes among different dimensions that matter in the skill acquisition process the model predicts that when identical schools compete for students specialization may arise as a competition strategy this serves rich students education goals well poorer students however may attend schools with specializations that do not cater to their relative strengths by doing so these poorer students complement the weaknesses of the richer students through peer effects and receive financial aid in return the empirical analysis provides strong support for the model s predictions about within school implications of specialization

better peers better scores a study of twin junior high school graduates in taiwan using data of twin students graduating from junior high schools between 2002 and 2004 in taiwan we estimate the effects of peers on high school joint entrance examination performance to alleviate the potential endogeneity of peer educational achievement linear models with twin fixed effect and instrumental variables are estimated quantile quantile with twin fixed effect and quantile with instrument variables regressions are also implemented to determine whether estimated peer effects differ at various locations of the testing scores conditional distributions positive and statistically significant peer effects are found to exist at the mean and at different quantile levels

university differences in the graduation of minorities in stem fields evidence from california the low number of college graduates with science degrees particularly among underrepresented minorities is of growing concern we examine differences across universities in graduating students in different fields using student level data on the university of california system during a period in which racial preferences were in place we show significant sorting into majors based on academic preparation with science majors at each campus having on average stronger credentials than their non science counterparts students with relatively weaker academic preparation are significantly more likely to leave the sciences and take longer to graduate at each campus we show the vast majority of minority students would be more likely to graduate with a science degree and graduate in less time had they attended a lower ranked university similar results do not apply for non minority students

choice of specialization do peers matter social influence is an important factor in learning and decision making we estimate peer influence on student choice of specialization using data on undergraduate students of a russian university information about individual social ties has been gathered from a questionnaire survey we show that specialization choice is significantly influenced by friends as well as by study partners the strongest effect is produced by friends who are study partners and those who have similar academic achievements reciprocal friendship ties have a stronger influence on the choice than nonreciprocal ones also the decision is affected by classmates with similar academic achievement the results allow us to better understand the mechanisms of peer effects in the specialization choice

peer group effects on the academic performance of italian students we analyse peer effects among students of a middle sized italian public university we explain students average grade in exams passed during their second level degree course on the basis of their pre determined measures of abilities personal characteristics and peer group abilities thanks to a rich administrative data set we are able to build a variety of definitions of peer groups describing different kinds of students interaction based on classes attended together or exams taken in the same session self selection problems are handled through two stage least squares estimations using as an instrument the exogenous assignment of students to different teaching classes in the compulsory courses attended during their first level degree course we find statistically significant positive peer group effects which are robust to the different definitions of peer group and to different measures of abilities

heterogeneity stratification and growth macroeconomic implications of community structure and school finance this paper examines how socioeconomic stratification and alternative systems of education finance affect inequality and growth agents interact through local public goods or externalities school funding neighborhood effects and economywide linkages complementary skills knowledge spillovers sorting families into homogeneous communities often minimizes the costs of existing heterogeneity but mixing reduces heterogeneity faster integration therefore tends to slow down growth in the short run yet raise it in the long run a move to state funding of education presents society with a similar intertemporal trade off local and global complementarities play major roles in determining the efficient social and educational structures copyright 1996 by american economic association

volatility estimation for bitcoin a comparison of garch models we explore the optimal conditional heteroskedasticity model with regards to goodness of fit to bitcoin price data it is found that the best model is the ar cgarch model highlighting the significance of including both a short run and a long run component of the conditional variance

competition between private and public schools vouchers and peer group effects a theoretical and computational model with tax financed tuition free public schools and competitive tuition financed private schools is developed students differ by ability and income achievement depends on own ability and on peers abilities equilibrium has a strict hierarchy of school qualities and two dimensional student sorting with stratification by ability and income in private schools high ability low income students receive tuition discounts while low ability high income students pay tuition premia tuition vouchers increase the relative size of the private sector and the extent of student sorting and benefit high ability students relative to low ability students

determinants of college major choice identification using an information experiment this article studies the determinants of college major choice using an experimentally generated panel of beliefs obtained by providing students with information on the true population distribution of various major specific characteristics students logically revise their beliefs in response to the information and their subjective beliefs about future major choice are associated with beliefs about their own earnings and ability we estimate a rich model of college major choice using the panel of beliefs data while expected earnings and perceived ability are a significant determinant of major choice heterogeneous tastes are the dominant factor in the choice of major analyses that ignore the correlation in tastes with earnings expectations inflate the role of earnings in college major choices we conclude by computing the welfare gains from the information experiment and find positive average welfare gains

industry specific capital and the wage profile evidence from the national longitudinal survey of youth and the panel study of income dynamics using data from the national longitudinal survey of youth 1979 96 and the panel study of income dynamics 1981 91 i seek to determine whether there is any net positive return to tenure with the current employer once we control for industry specific capital including total experience in the industry as an additional explanatory variable i show that the return to seniority is markedly reduced using gls while it virtually disappears using iv gls at both the one digit and three digit levels therefore it seems that what matters most for the wage profile in terms of human capital is industry specificity not firm specificity

interjurisdictional sorting and majority rule an empirical analysis the goal of this paper is to provide a comprehensive empirical analysis of majority rule and tiebout sorting within a system of local jurisdictions the idea behind the estimation procedure is to investigate whether observed levels of public expenditures satisfy necessary conditions implied by majority rule in a general equilibrium model of residential choice the estimator controls for observed and unobserved heterogeneity among households observed and unobserved characteristics of communities and the potential endogeneity of prices and expenditures as well as the self selection of households into communities of their choice we estimate the structural parameters of the model using data from the boston metropolitan area the empirical findings reject myopic voting models more sophisticated voting models based on utility taking provide a potential explanation of the main empirical regularities

volatility and return jumps in bitcoin abstract in this article we are interested in understanding the dynamics of bitcoin daily returns and volatility cryptocurrencies have very high unconditional volatility and are subject to sudden massive price swings we start with a standard log normal stochastic volatility model then explore two formulations which incorporate discontinuous jumps to volatility and returns jumps to volatility are permanent while jumps to mean returns have contemporaneous effects only results point to two high volatility periods the first from late 2013 to early 2014 likely associated to the mt gox incident the second covers the year of 2017 peaking on december likely driven by increased popular attention jumps to mean returns are specially relevant to capture large price variations mostly negative associated with formative events in cryptocurrency markets such as hacks and unsuccessful fork attempts

social ties within school classes the roles of gender ethnicity and having older siblings in this paper we identify the lines along which social ties between high school teenagers are primarily formed to this end we introduce interaction weights between pupils in the same school class that are a function of exogenous individual background characteristics such as gender ethnicity and having older siblings the resulting model with endogenous interactions and school specific fixed effects is estimated using data from the dutch national school youth survey nsys a survey in which in principle all pupils in a sampled class are interviewed by combining the 1992 1996 1999 and 2001 nsys data we are able to identify trends in social relationships of teenagers we find that the roles that gender and ethnicity play in how teenagers interact varies strongly across different types of behaviour for example going out shows strong within ethnicity interactions while expenditures on cell phones and on clothing exhibit mainly between girls interactions having older siblings has a minor effect on within school class social interactions there is weak evidence of decreased ethnic segregation within school classes during the decade considered

test scores educational opportunities and individual choice abstract a model combining student preferences for college with university admissions decisions is estimated to provide information on the role of test scores in the determination of post secondary educational opportunities in the u s in contrast to implications of much of the recent criticism of tests and their use we find that scholastic aptitude test scores are more strongly related to student application and choice of college quality than to college admissions decisions in addition although there is a substantial correlation between test scores and high school performance we find that both post secondary school preferences and ultimate opportunities are related as much to performance in high school as to test scores themselves although sat scores certainly exclude some persons from schools our findings indicate that they do not represent an overriding constraint on the college opportunities of high school graduates

does affirmative action work caste gender college quality and academic success in india public policy in modern india features affirmative action programs intended to reduce inequality that stems from a centuries old caste structure and history of disparate treatment by gender we study the effects of one such affirmative action program an admissions policy that fixes percentage quotas common across more than 200 engineering colleges for disadvantaged castes and for women we show that the program increases college attendance of targeted students particularly at relatively higher quality institutions an important concern is that affirmative action might harm intended beneficiaries by placing them in academic programs for which they are ill prepared we find no evidence of such adverse impacts

price discovery of cryptocurrencies bitcoin and beyond abstract academic research on cryptocurrencies is almost exclusively directed towards bitcoin we extend existing literature by performing various tests on efficiency of several cryptocurrencies and additionally link efficiency to measures of liquidity cryptocurrencies become less predictable inefficient as liquidity increases

what is a peer the role of network definitions in estimation of endogenous peer effects we employ a standard identification strategy from the peer effects literature to investigate the importance of network definitions in estimation of endogenous peer effects we use detailed information on friends in the national longitudinal study of adolescent health survey add health to construct two network definitions that are less ad hoc than the school grade cohorts commonly used in the educational peer effects literature we demonstrate that accurate definitions of the network seriously impact estimation of peer effects in particular we show that peer effects estimates on educational achievement smoking and drinking are substantially larger with our more detailed measures than with the school grade cohorts these results highlight the need to further understand how friendships form in order to fully understand implications for policy that alters the peer group mix at the classroom or cohort level

human capital specificity evidence from the dictionary of occupational titles and displaced worker surveys 1984 2000 measures of four basic skills constructed from the dictionary of occupational titles are used to examine the source of human capital specificity the measures are used to characterize the skill portfolio of each job and to construct distance measures between jobs wage losses in the displaced worker surveys are shown to be more closely associated with switching skill portfolios than switching industry or occupation code per se these switches represent large decreases in the skill portfolio in the postdisplacement job the recent evidence for industry specific capital is reexamined the results suggest a difference between fluid and crystallized skills

spatial price discrimination with heterogeneous products product heterogeneity is introduced into the context of spatial price discrimination many of the strong properties of the standard homogeneous goods case which are attained as a limit case here are shown to be no longer valid in particular the social optimum is no longer sustainable as a market equilibrium unless products are either identical or else very different

it s not your peers and it s not your friends some progress toward understanding the educational peer effect mechanism abstract using a new administrative panel data set from the university of maryland this paper explores conventional peer effects and the effects of socially proximate peers at a large public university where some students are randomly assigned to housing results show that there is little evidence of robust residential peer effects on undergraduate performance the impact of socially proximate peers characteristics on student achievement is then examined using an instrumental variables technique results indicate that social friends do not impact performance more than randomized peers the paper casts doubt on the notion that social tie formation is the route to peer effects and urges caution in the continued pursuit of peer effects in education without substantial empirical or theoretical innovation

estimating a dynamic model of household choices in the presence of income taxation the purpose of the article is to study the incentive and distributional consequences of income taxation the article analyzes tax changes in a dynamic setting the framework is estimated under a set of different identifying assumptions using parametric nonparametric and semiparametric techniques the empirical results focus on tax reforms in germany in the 1980s the article shows that these reforms did not significantly lower effective tax rates the findings also suggest that estimated elasticities for male labor supply are small ranging between 0 02 and 0 2

commitment and satisfaction in the classroom and on the field evidence from a division i liberal arts college within higher education there has been a persistent concern that student athlete commitments to their athletic activities are detrimental to their academic studies we collect data on student athl

admission tuition and financial aid policies in the market for higher education we present an equilibrium model of the market for higher education our model simultaneously predicts student selection into institutions of higher education financial aid educational expenditures and educational outcomes we show that the model gives rise to a strict hierarchy of colleges that differ by the educational quality provided to the students we also develop a new estimation procedure that exploits the observed variation in prices within colleges identification is based on variation in endowments and technology it does not rely on observed variation in potentially endogenous characteristics of colleges such as peer quality measures and expenditures we estimate the structural parameters using data collected by the national center for education statistics and aggregate data from peterson s and the national science foundation
