the informational role of stock and bond volume in a kyle 1985 model the sign of the correlation between a firm s debt and equity returns is the same as the sign of the cross market kyle s lambda the sign is positive negative if private information concerns the mean risk of the firm s assets we show empirically that information conveyed by order flows is primarily about asset means the cross market lambdas are quite large consequently the portions of bond and stock returns explained by order flows are highly correlated even though the order flows themselves are virtually uncorrelated

efficient and durable decision rules with incomplete information we compare six concepts of efficiency for economies with incomplete information depending on the stage at which individuals welfare is evaluated and on whether incentive constraints are recognized an example is shown in which an incentive efficient decision rule may be unanimously rejected by the individuals in the economy we define durable decision rules which can resist such unanimous rejection and show that efficient durable decision rules exist

the empirical content of the roy model this paper clarifies and extends the classical roy model of self selection and earnings inequality the original roy model based on the assumption that log skills are normally distributed is shown to imply that pursuit of comparative advantage in a free market reduces earnings inequality compared to the earnings distribution that would result if workers were randomly assigned to sectors aggregate log earnings are right skewed even if one sectoral distribution is left skewed most major implications of the log normal roy model survive if differences in skills are log concave however few implications of the model survive if skills are generated from more general distributions we consider the identifiability of the roy model from data on earnings distributions the normal theory version is identifiable without regressors or exclusion restrictions sectoral distributions can be identified knowing only the aggregate earnings distribution for general skill distributions the model is not identified and has no empirical content with sufficient price variation the model can be identified from multimarket data cross sectional variation in regressors can substitute for price variation in restoring empirical content to the roy model

social class family background and intergenerational mobility abstract this research examines the various approaches taken by economists and sociologists for analyzing intergenerational mobility social mobility models based on social classes arising from an occupational classification scheme are analysed a test for the statistical validity of classification schemes is proposed and tested using danish sample survey data that was first collected in 1976 and augmented in 2000 this is referred to as a homogeneity test and is a likelihood ratio test of a set of linear restrictions which define social classes for denmark it is shown that this test fails for an erikson goldthorpe classification system raising doubts about the statistical validity of occupational classification systems in general we also estimate regression models of occupational earnings household earnings and educational attainment using family background variables as covariates controlling for unobservables measurement error and simultaneous equation bias in these models homogeneity tests are also rejected we conclude from these results that the individual s family background has a small but significant impact on lifetime chances which is not captured by the erikson goldthorpe classification scheme

a liquidity based model of security design we consider the problem of the design and sale of a security backed by specified assets given access to higher return investments the issuer has an incentive to raise capital by securitizing part of these assets at the time the security is issued the issuer s or underwriter s private information regarding the payoff of the security may cause illiquidity in the form of a downward sloping demand curve for the security the severity of this illiquidity depends upon the sensitivity of the value of the issued security to the issuer s private information thus the security design problem involves a tradeoff between the retention cost of holding cash flows not included in the security design and the liquidity cost of including the cash flows and making the security design more sensitive to the issuer s private information we characterize the optimal security design in several cases we also demonstrate circumstances under which standard debt is optimal and show that the riskiness of the debt is increasing in the issuer s retention costs for assets

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

financial contracting under imperfect enforcement we develop a model ofnancial contracting under imperfect enforcement financial contracts are designed to keep entrepreneurs from diverting project returns but enforce ment is probabilistic and penalties are limited the model rationalizes the prevalence of straight debt and common stock and its predictions are consistent with a host of empirical capital structure regularities across countries acrossrms and across time

educational benefits and military service an analysis of enlistment reenlistment and veterans benefit usage 1991 2005 i introduction educational benefits for military veterans have become a prime recruiting tool in the all volunteer military force avf the primary education benefit for most of the avf era has been the montgomery gi bill mgib this version of the gi bill began in july 1985 and bears the name of its sponsor alabama representative sonny montgomery under this program eligible veterans who enroll in an education program approved by the veterans administration are eligible to receive up to 36 mo of benefits if they begin usage within 10 yr of separating from service veterans are only eligible for mgib benefits if they contribute 100 per month during their first year of service 1 from time to time three of the four military branches have supplemented the basic mgib benefit with college fund cf benefits research has indicated that educational benefits do in fact attract enlistments of high quality youth defined by the military services to be youth who possess a high school degree and who score above the youth population average of 50 on the armed forces qualification test afqt 2 although educational benefits attract more highly qualified youth into the military those benefits may be costly for at least two reasons first such youth may be more likely to separate from the military to use their benefits thus requiring higher rates of recruitment of new enlistees to maintain the size and quality of the force second higher benefits may increase the tendency of youth who separate from the military to use those benefits as well as increase the duration of usage of course this would not be surprising a growing body of research finds that college tuition subsidies raise college attendance interest in the potential behavioral effects of military educational benefits was recently heightened by a vigorous debate in congress over veterans benefits this debate culminated in the post 9 11 veterans education assistance act of 2008 which was passed in july 2008 becoming effective on august 1 2009 the act provides future veterans with substantially higher educational benefits than those available through the mgib this paper analyzes how gi bill benefits affect military retention and veterans benefit usage the analysis is useful for two reasons first as our review of the literature below indicates existing studies of the retention and usage effects of military education benefits are now quite dated second prior studies have all ignored issues relating to selection as a result the estimates of retention and usage effects found in them cannot be cleanly interpreted as pure incentive effects arising from benefit changes our analysis accounts for the possibility that higher veterans education benefits may attract youth who are more likely to separate and use those benefits conditional on their observables over the period of our analysis the nominal value of gi bill benefits were set legislatively and changed unpredictably we use the unpredictable evolution of the value of veterans education benefits over our data period to disentangle selection effects and incentive effects of benefit changes on retention and benefit usage our analysis makes use of administrative data that span the period 1988 2005 and contains annual information on every individual who entered active military service from the time of entry to the time of separation or if still in service until the end of fiscal year fy 2004 as shown below this was a period during which the real value of military educational benefits fluctuated considerably for those who separated details of educational benefit usage were available to us as of june 2005 if educational benefits do affect the retention behavior of military personnel or the educational decisions of military veterans their effects should be apparent in data over this period to highlight our key findings we estimate that a 10 000 increase in mgib benefits would increase the fraction of army veterans who use them within 2 yr of separation by 5 8 percentage points

the long term impact of military service on health evidence from world war ii and korean war veterans during the world war ii and korean war era the u s military freely distributed cigarettes to overseas personnel and provided low cost tobacco products on domestic military bases in fact even today the military continues to sell subsidized tobacco products on its bases using a variety of instrumental variables approaches to deal with nonrandom selection into the military and into smoking we provide substantial evidence that cohorts with higher military participation rates subsequently suffered more premature mortality more importantly we show that a large fraction 35 to 79 percent of the excess veteran deaths due to heart disease and lung cancer are attributable to military induced smoking

from the battlefield to the schoolyard the short term impact of the post 9 11 gi bill the post 9 11 gi bill brought about an enormous expansion in veteran education benefits roughly doubling the average maximum benefit level and generating large variation in the magnitude of benefit expansion across states using this context i explore how enrollment of older nontraditional students responds to educational subsidies the transition from a conditional cash transfer to a more in kind benefit affects the relative prices of different types of education pushing veterans to invest in more expensive plausibly higher quality schooling using a difference in differences strategy combined with state level variation in the degree of benefit expansion i find that the higher level of benefits increased college enrollment of separated veterans by between 15 and 20 percent while also shifting the composition of enrollment toward four year schools

assessing policies to equalize opportunity using an equilibrium model of educational and occupational choices abstract the inter generational correlation of education in the u s is tremendous for instance in psid data from 1990 young males with college educated parents had a 70 chance of attending college but those with high school drop out parents had only a 15 chance in this paper we analyze the impact of college attendance bonus schemes designed to increase college attendance rates and pv of lifetime income of youth from disadvantaged backgrounds of course policies that increase the supply of skilled labor may reduce the college wage premium see heckman et al heckman james lochner lance and taber christopher explaining rising wage inequality explorations with a dynamic equilibrium model of labor earnings with heterogeneous agents review of economic dynamics 1 1998a 1 58 heckman james lochner lance and taber christopher general equilibrium treatment effects a study of tuition policy american economic review 88 2 1998b 381 386 this may have the unintended consequence of wiping out most of the gains to the targeted groups the strength of such equilibrium effects on wages depends on the substitutability between different types of labor thus it is important to evaluate education subsidies within an equilibrium framework that allows for flexible patterns of substitution across factor inputs this is exactly what we do here using an overlapping generations equilibrium model of the u s labor market fit to psid data from 1968 to 1996 the model allows for imperfect substitution among types of labor differentiated by education gender age and ten 1 digit level occupations a much finer differentiation than has been considered in prior work we find that very large college attendance bonuses are necessary to equate college attendance rates between youth whose parents had only high school degrees or were high school dropouts and youth whose parents attended at least some college the size of these bonuses far exceeds any reasonable measure of college costs suggesting the costs the bonuses overcome are primarily psychic or effort costs for example youth from disadvantaged backgrounds may be poorly prepared for college this suggests that bonuses targeted at college age youth are probably a very inefficient way to reduce inequality earlier intervention is likely called for

choosing the field of study in postsecondary education do expected earnings matter abstract this paper examines the determinants of the choice of the college major when the length of studies and future earnings are uncertain we estimate a three stage schooling decision model focusing on the effect of expected earnings on major choice we control for dynamic selection through the use of mixture distributions exploiting variations across the french business cycle in the relative returns to the majors our results yield a very low though significant elasticity of major choice to expected earnings this suggests that at least for the french university context nonpecuniary factors are a key determinant of schooling choices

education choices and returns to schooling mothers and youths subjective expectations and their role by gender abstract in this paper we investigate the role of expected returns to schooling and of perceived risks of unemployment and earnings as determinants of schooling decisions moreover our data also allow us to analyze whether youths and or mothers expectations predict schooling decisions and whether this depends on the age and gender of the youth in particular we use mexican data that contain labor market expectations of mothers and youths we find that expected returns and risk perceptions are important determinants of schooling decisions the latter in particular from the perspective of the mother boys expectations predict the decision to enter college but not to enter high school while girls own expectations do not predict either of the two educational decisions mothers expectations are particularly strong predictors of their daughters decisions

skin in the game and moral hazard what determines securitization levels and should they be regulated to address these questions we develop a model where originators can exert unobservable effort to increase expected asset quality subsequently having private information regarding quality when selling abs to rational investors absent regulation originators may signal positive information via junior retentions or commonly adopt low retentions if funding value and price informativeness are high effort incentives are below first best absent regulation optimal regulation promoting originator effort entails a menu of junior retentions or one junior retention with size decreasing in price informativeness zero retentions and opacity are optimal among regulations inducing zero effort

education choices and returns on the labor and marriage markets evidence from data on subjective expectations in this paper we analyze the role of expected labor and marriage market returns as determinants of the college enrollment decisions of mexican high school graduates moreover we investigate whether the relative weights of these factors differ by gender we use data on individuals expectations regarding future labor market outcomes which we directly elicited from the youths and two different measures of marriage market returns first marriage market returns are proxied by the net supply of potential partners in the youths local marriage markets second we use data which elicits youths beliefs about their future spouse s earnings conditional on their own education level we find that labor market as well as marriage market returns are important determinants of the college enrollment decision however boys and girls preferences differ in terms of the relative role of the two determinants in that the relative weight of labor market versus marriage market returns is larger for boys than for girls

stochastic trade policy with asset markets abstract this paper uses a stockman dellas type two country two good stochastic general equilibrium model to consider the effects of commercial policy when asset markets are complete we show that i import and export tariffs do not have symmetric effects because interstate relative prices depend on the entire tariff structure ii when commercial policy is random and exogenously determined the ex post comparison of utility across states depends upon whether import or export tariffs are used and iii when endowments are random implying the optimal tariff varies across states the introduction of asset markets may be welfare reducing when only import tariffs are used

child labor and schooling responses to anticipated income in south africa abstract forward looking unconstrained households make child labor and schooling decisions considering their permanent income and weighing the relative returns to child time in various potential activities the timing of anticipated changes in income should have no effect on child labor and schooling in a setting where households can borrow against permanent income however this study documents large increases in schooling attendance and declines in total hours worked when black south african families become eligible for fully anticipatable social pension income as an explanation the data are most consistent with liquidity constraints for black elder males forcing rural families into less schooling for boys than they would choose absent the constraint perhaps because of schooling costs

optimal security design how should new securities be designed traditional theories have little to say on this the literature on capital structure and general equilibrium theories with incomplete markets take the securities firms issue as exogenous this paper explicitly incorporates the transaction costs of issuing securities and develops a model where the instruments that are traded are chosen optimally and the economy s market structure is endogenous among other things it is shown that the firm s income stream should be split so that in every state all payoffs are allocated to the security held by the group that values them most this abstract was borrowed from another version of this item

debt versus equity under asymmetric information in a world of asymmetric information in which only the insiders know the quality of the firm it is claimed that debt even if it is risky is more advantageous than outside equity because issuance of debt is less attractive to inferior firms the advantage to debt arises from the fact that it can keep unprofitable firms out of the market thus improving the average quality of firms in the market this advantage exists even if the firms cannot be perfectly sorted in the signaling equilibrium

optimal financial instruments debt and equity are developed as optimal financial instruments in a model where cash flows and control rights are allocated to investors endogenously when investment decisions must be made by a single party the debtholder s cash flows are fixed in order to provide the equityholder with efficient incentives for investment ownership of control may be transferred to the debtholder to attenuate the impact of asymmetric information concerning the investment opportunity on the efficiency of the decision making since the classic article by modigliani and miller 1958 a great deal of attention has been focused on the problem of determining the optimal capital structure of the firm spanning taxes and or transaction cost agency cost and signalling arguments have been offered as explanations for why a firm s cash flows might be split between debt and equity claimants in a particular way here we address the more basic question of the optimal design of the securities that firms issue the majority of the existing literature takes the form of the allowable financial instruments as given in defense of this approach it may be noted that to a first approximation firms have used two standard financial instruments debt and equity we argue here however that the characterization of the standard instruments used in much of the literature has been incomplete and that the incentives of decision makers within the firm cannot be completely understood until the problem is addressed from a more basic level than is typically done by concentrating on the cash flow characteristics of these instruments the equally important issue of the way the standard instruments distribute the control rights of the firm has been ignored as a consequence the objectives in corporate decision making have been assumed rather than developed endogenously we consider the allocation of cash flows and the distribution of control rights to optimal financial instruments in a security design problem by considering the design of securities in this way we are able to consider the

education choices in mexico using a structural model and a randomized experiment to evaluate progresa in this paper we evaluate the effect of a large welfare program in rural mexico for such a purpose we use an evaluation sample that includes a number of villages where the program was not implemented for evaluation purposes we estimate a structural model of education choices and argue that without such a framework it is impossible to evaluate the effect of the program and especially possible changes to its structure we also argue that the randomized component of the data allows us to identify a more flexible model that is better suited to evaluate the program we find that the program has a positive effect on the enrollment of children especially after primary school we also find that an approximately revenue neutral change in the program that would increase the grant for secondary school children while eliminating for the primary school children would have a substantially larger effect on enrollment of the latter while having minor effects on the former

adverse selection and security design this paper studies the problem of optimal security design by a privately informed entrepreneur in the context of a simple parametric model it is shown that the entrepreneur does not find it profitable to float an asset that affords her an informational advantage the reason is that with rational uninformed outside investors the entrepreneur faces adverse selection in the security market which prevents her from exploiting her position as an insider this is true whether or not she has market power in trading the asset consider a risk averse entrepreneur who is contemplating what security to issue the entrepreneur anticipates that during subsequent trading in the secondary market she will have private information on the payoff of her investment as well as on other risks in the economy the design of the asset is therefore influenced not only by a desire to share risk but also by informational considerations involving the potential for insider trading profits this paper studies the problem of optimal security design in the context of a simple parametric model with gaussian risks and cara utility trading in the secondary market is modelled via the static reduced form concept of rational expectations equilibrium in which uninformed outside investors use market prices to try to infer the private information of the entrepreneur or insider as she will sometimes be called it is shown that the entrepreneur does not find it profitable to float an asset that affords her an informational advantage an optimal asset entails a fully revealing rational expectations equilibrium and is perfectly correlated with the issuer s endowment risk the reason is that with rational outside investors the entrepreneur faces adverse selection in the security market which prevents her from exploiting her position as an insider she is better off foregoing her informational advantage and concentrating on her hedging motive alone in the particular setting described in the paper equity2 is an optimal asset since the entrepreneur has no privileged information regarding its payoff and it allows efficient risk sharing the issue of security design when prices have an informational role to play is just beginning to be researched closely related to this paper is the work of demange and laroque 1995 who use a competitive rational expectations model with noise traders to analyse the problem posed above except for some special cases however they are able to get only numerical results in comparison the present paper obtains partially revealing equilibria in a model in which all agents are rational furthermore demange and laroque

learning and complementarities in speculative attacks we study a model where the aggregate trading of currency speculators reveals new information to the central bank and affects its policy decision we show that the learning process gives rise to coordination motives among speculators leading to large currency attacks and introducing non fundamental volatility into exchange rates and policy decisions we show that the central bank can improve the ex ante effectiveness of its policy by committing to put a lower weight ex post on the information from the market and that transparency may either increase or decrease the effectiveness of learning from the market depending on how it is implemented

education policy and intergenerational transfers in equilibrium this paper compares partial and general equilibrium effects of alternative financial aid policies intended to promote college participation we build an overlapping generations life cycle heterogeneous agent incomplete markets model with education labor supply and consumption saving decisions altruistic parents make inter vivos transfers to their children labor supply during college government grants and loans as well as private loans complement parental transfers as sources of funding for college education we find that the current financial aid system in the u s improves welfare and removing it would reduce gdp by two percentage points in the long run any further relaxation of government sponsored loan limits would have no salient effects the short run partial equilibrium effects of expanding tuition grants especially their need based component are sizeable however long run general equilibrium effects are 3 4 times smaller every additional dollar of government grants crowds out 20 30 cents of parental transfers

capital structure and signaling game equilibria in this article we model the financing decisions of a firm as a sequential signaling game we prove that when insiders have perfect information regarding the firm s future case flows the application of refinements to the set of admissible equilibria leads to the dominance of debt over equity financing however we show that when insiders observe the firm s cash flows imperfectly there may exist sequential equilibria in which this pecking order breaks down and some firms strictly prefer equity to debt financing we also prove that despite the breakdown of the pecking order the announcement effect of equity financing will be negative relative to debt financing

the effect of school quality on educational attainment and wages the paper examines the effects of school pupil teacher ratios and type of school on educational attainment and wages using the british national child development survey ncds the ncds is a panel survey which has followed a cohort of individuals born in march 1958 and has a rich set of background variables recorded throughout the individual s life the results suggest that once we control for ability and family background the pupil teacher ratio has no impact on educational qualifications or on male wages it has an impact on women s wages at the age of 33 particularly those of low ability we also find evidence that those who attend selective schools have better educational outcomes and in the case of men higher wages at the age of 33 the impact is higher for the type of individuals who are less likely not to attend selective schools but for whom a comparison group does exist among those attending

the pecking order debt capacity and information asymmetry abstract we quantify the empirical relevance of the pecking order hypothesis using a novel empirical model and testing strategy that addresses statistical power concerns with previous tests while the classificatory ability of the pecking order varies significantly depending on whether one interprets the hypothesis in a strict or liberal e g modified pecking order manner the pecking order is never able to accurately classify more than half of the observed financing decisions however when we expand the model to incorporate factors typically attributed to alternative theories the predictive accuracy of the model increases dramatically accurately classifying over 80 of the observed debt and equity issuances finally we show that what little pecking order behavior can be found in the data is driven more by incentive conflicts as opposed to information asymmetry

economic interpretations of intergenerational correlations science itself for example see galton s 1869 study of the eminence of relatives or his 1889 analysis of the heights of parents and children but extensive use of economic theory to interpret these correlations is much more recent using basic economic concepts such as supply demand investment incentives missing markets and so on theorists hope to explain how and why status is correlated across generations economic theory might provide a unified treatment of a variety of socioeconomic indicators such as earnings income occupation or wealth or it might predict how taxes subsidies and economic regulation affect intergenerational mobility and the operation of markets however while the subject matter earnings consumption wealth occupa tion is clearly interesting to economists it could nonetheless be the case that beyond basic questions of measurement economic theory has not improved our understanding of intergenerational mobility goldberger 1989 is quite explicit in this contention by emphasizing the distinction between genes and environment and by using statistical theory as its main analytical tool the paper by samuel bowles and herbert gintis in this issue implicitly concurs with goldberger we take this challenge very seriously what characterizes an economic approach to mobility while biologists and bowles and gintis distinguish endowments and investments by their source genetic versus environmental factors one focus of economic theorists is motiva

a human capital model of the effects of ability and family background on optimal schooling levels this paper develops a theoretical model of optimal schooling levels where ability and family background are the central explanatory variables we derive schooling demand and supply functions based on individual wealth maximization using nlsy79 data we stratify our sample into one year fte work experience cohorts for 1985 1989 mincer s 1974 overtaking cohort the years of work experience at which individuals observed earnings approximately equal what they would have been based on schooling and ability alone corresponds to 13 fte years of work experience yielding on average a rate of return of 9 6 percent and an average optimal 11 4 years of schooling

weighing the military option the effects of wartime conditions on investments in human capital serving in the military is an important vehicle through which young americans invest in their human capital as such changes in the desirability of military service may affect the attainment of enlistment requirements such as a high school degree or equivalent using american community survey data we find that exposure to home state combat fatalities during the iraq and afghanistan wars decreased the probability of high school completion and increased the probability of general equivalency diploma completion using military data we confirm that exposure to home state fatalities selectively deterred some individuals from enlisting the results suggest military service and educational investments are complements jel i20 i26 j24

positive information from equity issue announcements abstract the myers and majluf 1984 model predicts a nonpositive price reaction to an announcement of a new issue of equity this paper shows that the myers and majluf result is a direct outcome of their assumption that all potential projects facing the firm have a nonnegative net present value refining the myers and majluf model by allowing for the realistic possibility of potential projects having negative net present values leads to different predictions the refined model predicts positive as well as negative stock price responses consistent with recent empirical evidence concerning the stock price effects of new stock issues

demand and supply side determinants of conditional cash transfer program effectiveness summary the programa nacional de becas estudiantiles is a conditional cash transfer program designed to promote human capital accumulation and reduce poverty among argentine youth this study follows a 1999 cohort of students for five years and uses matching methods with a comparison group of students excluded due to quotas to estimate average and marginal program impacts multilevel methods are used to explore the role of program management and execution in explaining variation between schools in student outcomes the results suggest that the becas program improved students attendance and performance in part through program conditions requiring good attendance and academic progress for continued scholarship receipt

college education and the midcentury gi bills the midcentury gi bills were the largest direct scholarship program for higher education in american history i use a comparison group created by the sharp cutoff date of the korean war gi bill to evaluate the effects of the korean war gi bill on postsecondary educational attainment and access to college by the disadvantaged i then bound the likely effects of the world war ii gi bill based on elasticities estimated for the korean war gi bill and new estimates using older veterans as a comparison group for younger ones i find that the combination of the korean war and wwii gi bills probably increased total postsecondary attainment among all men born between 1921 and 1933 by about 15 to 20 percent with smaller effects for surrounding cohorts the impacts of both programs on college attainment were apparently concentrated among veterans from families in the upper half of the distribution of socioeconomic status

informed lending and security design we examine the role of security design when lenders make inefficient accept or reject decisions after screening projects lenders may be either too conservative in which case they reject positive npv projects or too aggressive in which case they accept negative npv projects in the first case the uniquely optimal security is debt in the second case it is levered equity in equilibrium profitable projects that are relatively likely to break even are financed with debt while less profitable projects are financed with equity highly profitable projects are financed by uninformed arm slength lenders professional lenders have specialized expertise in screening projects unlike the typical entrepreneur to whom they lend they have been exposed to a wide variety of projects in the past professional lenders have experienced loan officers and analysts who know precisely what information is relevant how to treat soft information such as management quality and how to weigh the various pieces of information in making a forecast of the project s cash flows and default risk this paper examines how securities should be optimally designed when lenders make inefficient accept or reject decisions after screening projects in our model screening generates an informative albeit private signal about the project s profitability high signals indicate a positive net present value npv and low signals indicate a negative npv where the project s npv is increasing

dynamic female labor supply the increase in female employment and participation rates is one of the most dramatic changes to have taken place in the economy during the last century however while the employment rate of married women more than doubled during the last 50 years that of unmarried women remained almost constant to empirically analyze these trends we estimate a female dynamic labor supply model using an extended version of eckstein and wolpin 1989 to compare the various explanations in the literature for the observed trends this dynamic model provides a much better fit to the life cycle employment pattern than a static version of the model and a standard static reduced form model heckman 1979 the main finding using the dynamic model is that the rise in education levels accounts for about 33 percent of the increase in female employment and the rise in wages and narrowing of the gender wage gap account for another 20 percent while about 40 percent remains unexplained by observed household characteristics we show that this unexplained portion can be empirically attributed to cohort specific changes in preferences or the costs of child rearing and household maintenance finally the decline in fertility and the increase in divorce rates account for only a small share of the increase in female employment rates

design and marketing of financial products marketing costs are introduced into the security design environment outlined in allen and gale 1988 it is shown that splitting the firm s cash flow between products enhances their investor appeal and reduces marketing costs we also explain how the extremal product design in allen and gale is thereby avoided and how in simple cases debt equity or warrants can be optimal furthermore we illustrate in general terms how the optimal solution employs portfolios of option type products and we give an example of two optimal products that share profits in seven of eight states article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

trading frenzies and their impact on real investment we study a model in which a capital provider learns from the price of a firm s security in deciding how much capital to provide for new investment this feedback effect from the financial market to the investment decision gives rise to trading frenzies in which speculators all wish to trade like others generating large pressure on prices coordination among speculators is sometimes desirable for price informativeness and investment efficiency but speculators incentives push in the opposite direction so that they coordinate exactly when it is undesirable we analyze the effect of various market parameters on the likelihood of trading frenzies to arise

life cycle schooling and dynamic selection bias models and evidence for five cohorts of american males this paper examines an empirical regularity found in many societies that family influences on the probability of transiting from one grade level to the next diminish at higher levels of education we examine the statistical model used to establish the empirical regularity and the intuitive behavioral interpretation often used to rationalize it we show that the implicit economic model assumes myopia the intuitive interpretive model is identified only by imposing arbitrary distributional assumptions onto the data we produce an alternative choice theoretic model with fewer parameters that rationalizes the same data and is not based on arbitrary distributional assumptions

extreme screening policies abstract we show that a lender often experiences increasing marginal returns to screening in a standard setting where the lender decides how intensively to screen the projects of prospective borrowers the increasing marginal returns imply that even small changes in industry parameters can produce large changes in equilibrium screening intensity in particular a small reduction in the expected return from borrowers projects can produce a pronounced increase in the screening of prospective borrowers with substantial corresponding welfare effects

financing patterns around the world are small firms different using a firm level survey database covering 48 countries we investigate how financial and institutional development affects financing of large and small firms our database is not limited to large firms but includes small and medium size firms and data on a broad spectrum of financing sources including leasing supplier development and informal finance small firms and firms in countries with poor institutions use less external finance especially bank finance protection of property rights increases external financing of small firms significantly more than of large firms mainly due to its effect on bank finance small firms do not use disproportionately more leasing or trade finance compared with larger firms so these financing sources do not compensate for lower access to bank financing of small firms we also find that larger firms more easily expand external financing when they are constrained than small firms finally we find suggestive evidence that the pecking order holds across countries

valuing school quality better transport and lower crime evidence from house prices housing prices within urban areas exhibit highly localized variation that cannot be explained solely by differences in the physical attributes of dwellings we consider the role of local amenities and disamenities in generating price variation within urban areas focusing on three highly policy relevant urban issues transport accessibility school quality and crime our survey of the recent empirical literature highlights what is known and what is not known on these issues and considers the relevance and reliability of this evidence for policy design and evaluation although there are serious empirical challenges we argue that research on housing values based on careful research designs can offer credible estimates of the social value of place specific attributes and amenities

the slowdown in american educational attainment relative to those for high school graduates lifetime earnings for college graduates are higher for more recent cohorts at the same time across successive cohorts born after 1950 there is a stagnation in the fraction of high school graduates that go on to complete a college degree what explains this phenomenon i formulate a life cycle model of human capital accumulation in college and on the job where successive cohorts decide whether or not to acquire a college degree as well as the quality of their college education cohorts differ by the sequence of rental price per unit of human capital they face and by the distribution of initial human capital across individuals my model reproduces the observed pattern in college attainment for the 1920 1970 birth cohorts the stagnation in college attainment is due to the decrease in the growth rate of the rental price per unit of human capital commencing in the 1970s my model also generates about 80 of the increase in lifetime earnings for college graduates relative to those for high school graduates observed across cohorts

a new test of borrowing constraints for education we discuss a simple model in which parents and children make investments in the children s education investments for other purposes and parents can transfer cash to their children we show that for an identifiable set of parent child pairs parents will rationally under invest in their child s education for these parent child pairs additional financial aid will increase educational attainment the model highlights an important feature of higher education finance the expected family contribution efc that is based on income assets and other factors the efc is neither legally guaranteed nor universally offered our model identifies the set of families that are disproportionately likely to not provide their full efc using a common proxy for financial aid we show in data from the health and retirement study that financial aid increases the educational attainment of children whose families are disproportionately likely to under invest in education financial aid has no effect on the educational attainment of children in other families the theory and empirical evidence identifies a set of children who face quantitatively important borrowing constraints for higher education

international migration remittances and schooling evidence from el salvador abstract we examine the effect of remittances from abroad on households schooling decisions using data for el salvador following the massive war related emigration of the 1980s remittances became a significant source of household income throughout the 1990s we use the cox proportional hazard model to examine the determinants of school attendance measuring income from a source that is uncorrelated with parental schooling remittances we find that remittances have a large significant effect on school retention we estimate that while household income net of remittances has a small though significant impact on the hazard of leaving school in rural and urban areas remittances have a much larger impact on the hazard of leaving school in urban areas the effect of remittances is at its smallest 10 times the size of the effect of other income in rural areas the effect of remittances is about 2 6 times that of other income our finding is of interest in that it suggests that subsidizing school attendance particularly in poor areas may have a large impact on school attendance and retention even if parents have low levels of schooling

structural estimates of the intergenerational education correlation using a structural dynamic programming model we investigate the relative importance of family background variables and individual specific abilities in explaining cross sectional differences in schooling attainments and wages each type of ability is the sum of one component correlated with family background variables and a residual orthogonal component which is purely individual specific household background variables especially parents education account for 68 of the explained cross sectional variations in schooling attainments while ability correlated with background variables accounts for 17 and pure individual specific ability accounts for 15 interestingly individual differences in wages are mostly explained by pure individual specific abilities as they account for as much as 73 of the explained variations in wages family background variables account for only 19 while ability endowments correlated with family background account for 8 copyright 2003 john wiley sons ltd

information production dilution costs and optimal security design abstract we investigate the problem of a firm wishing to finance a project by issuing securities under asymmetric information we find that when outside investors can produce noisy information on the firm s quality the degree of information asymmetry resulting in equilibrium is endogenous and depends on the information sensitivity of the security issued thus in contrast to the prediction of the pecking order theory see e g myers and majluf j financial econom 13 1984 187 a security with low sensitivity to private information such as debt does not always dominate one with high information sensitivity such as equity a firm s preference for equity rather than debt depends on the costs of information production the precision of the information production technology and the extent of the information asymmetry we also study the optimal security design problem and find that depending on the cost and precision of the information production technology risky debt or a composite security with a convex payoff emerges as optimal securities

balance of trade announcements and asset prices influence on equity prices exchange rates and interest rates abstract this paper examines the informational impact of traded balance announcements on asset prices including equities currrencies long and short term debt instruments and financial futures this study finds that in the 1980s prior to the 1985 plaza agreement for international economic cooperation information in trade balance announcements seem to have influenced only interest rates however in the 1985 1987 period such announcements also influenced stock prices and currency values these influences intensity further in the 1987 1988 period thus asset prices are sensitive to news in trade balance announcements and this sensitivity seems to have increased significantly in recent years with important implications for asset pricing models and economic policy formulation jel f30

optimal incentives and securitization of defaultable assets abstract we study optimal securitization in the presence of an initial moral hazard a financial intermediary creates and then sells to outside investors defaultable assets whose default risk is determined by the unobservable costly effort exerted by the intermediary we calculate the optimal contract for any given effort level and show the natural emergence of extreme punishment for defaults under which investors stop paying the intermediary after the first default with securitization contracts optimally designed we find securitization improves the intermediary s screening incentives furthermore the equilibrium effort level and the surplus converge to their first best levels with sufficiently many assets

the impacts of teacher working conditions and human capital on student achievement evidence from brazilian longitudinal data abstractwe use a new longitudinal matched student teacher data from brazil to examine the impacts of teacher human capital and working conditions on student learning controlling for student teache

on the roles of international financial markets and their relevance for economic policy a general equilibrium approach to international finance and macroeconomics has been developed recent work associated with this development provides useful tools for interpreting evidence and evaluating alternative policy options important issues to which these advances have been applied include the choice of an exchange rate system the high variability of exchange rates the effects of budget deficits sterilized foreign exchange market intervention and monetary and fiscal policies the causes and consequences of large and variable current account deficits or surpluses and their connections with exchange rates and the development of more open and sophisticated international financial markets copyright 1988 by ohio state university press

adverse selection and convertible bonds informational asymmetries between a firm and investors may lead to adverse selection in capital markets this paper demonstrates that when the market obtains noisy information about a firm over time this adverse selection problem can be costlessly solved by issuing callable convertible bonds with restrictive call provisions such securities can be designed to make the payoff to new claimholders independent of the private information of the manager this eliminates the possibility of any dilution of equity or underinvestment and implements the symmetric information outcome in either a pooling or a separating equilibrium the same first best efficient outcome can also be implemented by issuing floating price and mandatory convertibles

secondary market liquidity and security design theory and evidence from abs markets we develop and empirically test a theory of optimal security design under adverse selection accounting for strategic trading by uninformed investors who will liquidate a security in secondary markets only if their idiosyncratic carrying costs exceed the security s expected trading loss such investors demand primary market discounts equaling expected carrying costs borne plus trading losses incurred issuers minimize the total illiquidity discount by splitting cash flow into tranched debt claims with liquidity predicted to increase with seniority while the optimal number of tranches increases with underlying cash flow risk empirical tests confirm our model predictions

market based corrective actions many economic agents take corrective actions based on information inferred from market prices of firms securities examples include directors and activists intervening in the management of firms and bank supervisors taking actions to improve the health of financial institutions we provide an equilibrium analysis of such situations in light of a key problem if agents use market prices when deciding on corrective actions prices adjust to reflect this use and potentially become less revealing we show that market information and agents information are complementary and discuss measures that can increase agents ability to learn from market prices the author 2009 published by oxford university press on behalf of the society for financial studies all rights reserved for permissions please email journals permissions oxfordjournals org oxford university press

u s war costs two parts temporary one part permanent military spending fatalities and the destruction of capital all of which are immediately felt and are often large are the most overt costs of war they are also relatively short lived but the costs of war borne by combatants and their caretakers which includes families communities and the modern welfare state tend instead to be lifelong in this paper i show that a significant component of the budgetary costs associated with u s wars is long lived one third to one half of the total present value of historical war costs are benefits distributed over the remaining life spans of veterans and their dependents even thirty years after the end of hostilities typically half of all benefits remain to be paid estimates of the costs of injuries and deaths suggest that the private burden of war borne by survivors namely the uncompensated costs of service related injuries are also large and long lived

early and late human capital investments borrowing constraints and the family we develop a dynastic human capital investment framework to study the importance of family borrowing constraints and uninsured labor market risk as well as the process of intergenerational ability

feedback effects and asset prices feedback effects from asset prices to firm cash flows have been empirically documented this finding raises a question for asset pricing how are asset prices determined if price affects fundamental value which in turn affects price in this environment by buying assets that others are buying investors ensure high future cash flows for the firm and subsequent high returns for themselves hence investors have an incentive to coordinate which may generate self fulfilling beliefs and multiple equilibria using insights from global games we pin down investors beliefs analyze equilibrium prices and show that strong feedback leads to higher excess volatility

residential location work location and labor market outcomes of immigrants in israel we develop and estimate a comprehensive dynamic programming dp model for the joint decisions of residential location employment location occupational choices and labor market outcomes we use data on immigrants from the former soviet union fsu we provide an extensive empirical evaluation of policies that have been designed to affect the residential and employment location decisions of the migrant population the results shed new and important light on several issues regarding this group of immigrants we find large regional differences in wages for the white collar workers but only little differences for the blue collar workers a careful examination of a number of policy measures indicate that a direct subsidy in the form of a lump sum transfer is most effective in achieving the government stated goal of inducing people to reside in the northern region of the galilee and southern region of the negev other policies such as rental and wage subsidies can also be quite effective but these are more difficult to administer

public trading and private incentives this article studies the link between public trading and the activity of a firm s large shareholder who can affect firm value public trading results in the formation of a stock price that is informative about the large shareholder s activity this increases the latter s incentives to engage in value increasing activities indeed if he has to liquidate part of his stake before the effect of his activity is publicly observed a more informative price rewards him for his activity implications are derived for the decision to go public capital structure and security design we consider a firm with a large shareholder and otherwise dispersed shares which are publicly traded the block holder is an insider in the sense that he can undertake actions that directly affect the firm s value moreover the insider might not take all value increasing actions as at least some of them involve a private cost for him in other words there is an incentive problem the article s main premise is that public trading as part of the price formation process generates information not only about exogenous factors affecting firm value but also about the insider s activity for instance as a result of public trading a firm s stock price will incorporate the market s evaluation of how a controlling shareholder allocates corporate resources we identify two sources of incentives for the insider to engage in activities that will increase firm value the first one is his stake in the firm since the insider participates in a value increase in proportion to his equity stake a larger stake increases the benefit to him from the firm value being high the view that large shareholders affect firm value is indeed widespread shleifer and vishny 1997 they alleviate the free rider problem pervasive in firms with passive dispersed investors unable or unwilling to affect the firm s operations that is outsiders

heterogeneity in ordered choice models a review with applications to self assessed health discrete variables that have an inherent sense of ordering across outcomes are commonly found in large data sets available to many economists and are often the focus of research however assumptions underlying the standard ordered probit which is usually used to analyse such variables are not always justified by the data this study provides a review of the ways in which the ordered probit might be extended to account for additional heterogeneity differing from other reviews in scope application and relevance in economic settings a series of issues pertaining to choices of variables and the economic assumptions underlying each model are discussed in the context of measuring the underlying health of respondents the models are applied to a wave of the household income and labour dynamics in australia survey in order to check the appropriateness of such assumptions in an applied context

education earnings and the canadian g i bill canadian second world war veterans benefited from an extensive educational pro gram similar to the u s g i bill because of differences in military enlistment rates how ever a much lower fraction of quebec men were eligible for these benefits than men from other provinces building on this fact we analyse inter cohort patterns of education and earnings for english speaking men from ontario using french speaking men from quebec as a control group we find that the instrumental variables estimates of the return to school ing are typically as big or bigger than the corresponding ols estimates jel classification j24 i21

college entry by blacks since 1970 the role of college costs family background and the returns to education college enrollment of black 18 19 year old high school graduates declined from 1980 through 1984 and then rebounded after 1984 this paper presents data from a time series of cross sections of 18 19 year old youths from 1973 through 1988 to test the role of family background direct college costs local economic conditions and returns to college in driving these trends the evidence suggests that on the one hand increases in direct college costs were driving enrollment rates downward throughout the eighties on the other hand dramatic increases in average parental education for black youths exerted upward pressure on college enrollment by blacks particularly in the latter half of the decade the net effect of these two factors contributed to the pattern of decline and recovery observed during the eighties

optimality of debt under flexible information acquisition we study the optimality of debt through the interaction between se curity design and information acquisition an impatient seller designs an asset backed security and a buyer decides whether to buy it to provide liquidity facing dierent securities the buyer has incentives to acquire in formation from dierent aspects of the fundamental which in turn aects security design speci cally the buyer bene ts from information acqui sition at the expense of the seller through adverse selection the seller hence deliberately designs the security to induce the buyer to acquire the information least harmful to the seller s interest since securities can be designed in arbitrary ways the resulting incentive to acquire information is very exible thus we introduce exible information acquisition to capture this interaction we show that debt is uniquely optimal com pared with the security design literature we neither assume monotonicity of the feasible securities nor impose various distributional assumptions on the fundamental or information structures fixed aggregate cash ow and homogeneous information cost are two key factors driving the results jel d86 d82 g32

fostering educational enrolment through subsidies the issue of timing summary the purpose of this paper is to build a dynamic structural model of educational choices in which cognitive skills shape decisions the model is estimated by maximum likelihood using cohort data where individuals are observed from birth to the middle of their working life these data are unique in that they include cognitive skills test scores collected as early as age 7 we then investigate how alternative policies foster educational enrolment in particular we simulate the effect of two subsidies different in the timing of disbursement the first consists of grants assigned directly to individuals aged between 16 and 18 the second is assigned to the parents earlier on when the cohort is still in its childhood the latter subsidy affects cognitive skills accumulation and in turn educational choices our results suggest that a grant fosters enrolment at the lowest cost but the parental income subsidy generates more welfare as measured by a class of social welfare functions nevertheless these differences in costs and welfare are small overall the results reinforce the view that government investments in cognitive skill accumulation during childhood are worthwhile however the results also indicate that such investments should be well structured to ensure a high return copyright 2010 john wiley sons ltd

optimal design of securities under asymmetric information a firm must decide what security to sell to raise external capital to finance a profitable investment opportunity there is ex ante asymmetry of information regarding the probability distribution of cash flow generated by the investment in this setting we derive necessary and sufficient conditions for a security to be optimal uniquely optimal that is for pooling at this security to be an the unique equilibrium outcome using these conditions we show that the debt contract is uniquely optimal if and only if cash flows are ordered by strict conditional stochastic dominance finally we derive an equivalence relationship between optimal security designs and designs that minimize mispricing
