implications of bid design and willingness to pay distribution for starting point bias in double bounded dichotomous choice contingent valuation surveys we examine starting point bias in double bounded dichotomous choice contingent valuation surveys we investigate 1 the seriousness of the biases for the location and scale parameters of the willingness to pay wtp in the presence of starting point bias 2 whether or not these biases depend on the distribution of wtp and on the bid design and 3 how well a commonly used diagnostic for starting point bias a test of the null that bid set dummies entered in the right hand side of the wtp model are jointly equal to zero performs under various circumstances monte carlo simulations suggest that the effect of ignoring starting point bias depends on the bid design and on the true distribution of wtp a well balanced symmetric bid design may result in very modest biases even when the anchoring mechanism is very strong the power of bid set dummies in detecting starting point bias is low they tend to account for misspecifications in the distribution assumed by the researcher for the latent wtp rather than capturing the presence of starting point bias

the influence of collective action on the demand for voluntary climate change mitigation in hypothetical and real situations in this experiment we investigate determinants of the individual demand for voluntary climate change mitigation subjects decide between a cash prize and an allowance from the eu emissions trading scheme for one ton of co2 that will be deleted afterwards we vary the incentives of the decision situation in which we distinguish between real monetary incentives and a hypothetical decision situation with and without a cheap talk script furthermore decisions were implemented either as purely individual or as a collective action using majority voting we observe a significant hypothetical bias in the demand for voluntary climate change mitigation in case of the individual decision situation this bias is caused solely by subjects with low income collective decision making affects demand positively in the hypothetical decision situation only

assessing the impact of crop diversification on farm poverty in india summary crop diversification into high value crops hvcs can be a strategy to improve livelihood outcomes for farmers using data from a nationally representative survey we establish that households diversifying toward hvcs are less likely to be poor the biggest impact being for smallholders furthermore using continuous treatment matching we establish the relationship between degree of diversification share of area dedicated to hvc and poverty growers of hvcs need to allocate at least 50 area to hvcs to escape poverty effect of diversification on poverty is in general positive but it withers after a threshold probably because of constraints i e capital on smaller farms and labor on larger ones

willingness to pay for voluntary climate action and its determinants field experimental evidence the determinants of individual voluntary climate action vca in combating climate change and its potential scale are frequently debated in public but largely underresearched we provide estimates of the willingness to individually reduce eu greenhouse gas emissions by one ton using the european union emissions trading scheme estimates are derived from an online field experiment with a large highly heterogenous and internet representative sample of voting aged germans jointly estimating willingness to pay wtp non indifference to vca and prior knowledge we uncover important determinants of preferences for vca such as education the information structure among the population and exogenous environmental conditions

land tenure price shocks and insurgency evidence from peru and colombia abstract the paper examines how property arrangements a key determinant of rural income influence armed conflict in the presence of commodity price shocks using detailed data on district level land tenure crop produce and conflict intensity in peru and colombia estimates show that exogenous negative price shocks increase the intensity of conflict in districts with a greater presence of individual ownership relative to other types of land tenure the finding is consistent with small landowners in the export sector experiencing a sharper downturn in labor market outcomes thus reducing the opportunity cost of participating in insurgent groups

the illusory effects of saving incentives on saving the authors evaluate research on how tax based saving incentives iras and 401 k s affect saving previous research overstates the impact of the incentives on saving by failing to account for several issues households with saving incentives have stronger tastes for saving than others saving incentives have interacted with debt nonfinancial assets financial markets and pensions and saving incentives represent pretax balances whereas taxable accounts represent posttax balances accounting for these issues essentially eliminates the impact of saving incentives on saving the authors conclude that little if any of the contributions to existing saving incentives have raised saving

formative experiences and portfolio choice evidence from the finnish great depression we trace the impact of formative experiences on portfolio choice plausibly exogenous variation in workers exposure to a depression allows us to identify the effects and a new estimation approach makes addressing wealth and income effects possible we find that adversely affected workers are less likely to invest in risky assets this result is robust to a number of control variables and it holds for individuals whose income employment and wealth were unaffected the effects travel through social networks individuals whose neighbors and family members experienced adverse circumstances also avoid risky investments

collective choice in the commons experimental results on proposed allocation rules and votes we analyse and empirically examine a multi level common pool resource cpr game consisting of a collective choice level game and an operational level game in the collective choice game participants anonymously propose allocation rules to be used in the operational game and vote anonymously on the proposed rules majority and unanimity rules are investigated our major finding is that both types of voting rules substantially increase efficiency relative to a baseline with no opportunity for collective choice but the distributional consequences of the rules differ to understand the process by which efficiency is improved better we examine four predictive theories related to proposals votes and outcomes

the effect of prenatal stress on cooperation evidence from violent conflict in uganda abstract are preferences endogenously determined in the womb we play a public goods game with ugandan children born during a conflict characterised by high civilian victimisation children whose caregivers suffer from post traumatic stress disorder are more likely to free ride in the game genetic and environmental factors alone do not explain the relationship but children s 2d 4d digit ratio a marker of fetal hormone exposure associated with epigenetic effects of maternal distress does our findings extend the fetal origins literature to the domain of preferences by reducing next generation s taste for cooperation conflict may have father reaching economic consequences than previously thought

intra household gender disparity in school choice evidence from private schooling in india abstractthis paper explores gender inequality within households in the decision of private versus government school choice in india using a three period longitudinal dataset on rural households from uttar pradesh a northern state of india this paper estimates a household fixed effects model and finds that there is an intra household gender bias of 6 percentage points in private school enrolment among children aged 6 16 years contrary to the trend in overall enrolment the gender gap in private school choice is rising over time and is more pronounced in villages with a larger cost difference between private and government schooling this finding remains robust even after controlling for average school quality and considering potential endogeneity of the cost variables

fairness spillovers the case of taxation abstract it is standardly assumed that individuals react to perceived unfairness or norm violations in precisely the same area or relationship where the original offense has occurred however grievances over being exposed to injustice may have even broader consequences and also spill over to other contexts causing non compliant behavior there we present evidence that such fairness spillovers can incur large economic costs a belief that there is unfairness in taxation in the sense that the rich do not pay enough taxes is associated with a twenty percent higher level of paid absenteeism from work

pride and prejudice using ethnic sounding names and inter ethnic marriages to identify labour market discrimination labour markets discriminate against workers with particular ethnic sounding names we use non random sorting into interethnic marriage and salient differences between sephardic and ashkenazi surnames to evaluate the causal impact of sephardic affiliation on wages using the 1995 israeli census we estimate the effect of a sephardic sounding surname on wages we first compare the wages of israeli jewish males born to sephardic fathers and ashkenazi mothers sa who are more likely to carry a sephardic surname with the wages of israeli jewish males born to ashkenazi fathers and sephardic mothers as we find that israeli labor markets discriminate based on perceived ethnicity sa workers earn significantly less than their as counterparts we then exploit the custom of women to adopt their husbands surnames to disentangle actual ethnicity from the ethnicity perceived by the market consistent with ethnic discrimination based on surnames we find that it is father in law s ethnicity rather than father s ethnicity that shapes female wage rates finally we find that labor markets discriminate based on surname only when those names provide additional information about ethnicity when ethnicity can be discerned from skin tone surnames do not provide additional explanatory power with respect to wages

sectoral conflict and foreign economic policy 1914 1940 the period from 1914 to 1940 is one of the most crucial and enigmatic in modern world history and in the history of modern u s foreign policy world war i catapulted the united states into international economic and political leadership yet in the aftermath of the war despite grandiose wilsonian plans the united states quickly lapsed into relative disregard for events abroad it did not join the league of nations disavowed responsibility for european reconstruction would not participate openly in many international economic conferences and restored high levels of tariff protection for the domestic market only in the late 1930s and 1940s after twenty years of bitter battles over foreign policy did the united states move to center stage of world politics and economics it built the united nations and a string of regional alliances underwrote the rebuilding of western europe almost single handedly constructed a global monetary and financial system and led the world in commercial liberalization

disproportional control rights and the governance role of debt we examine the governance role of debt in the context of u s based dual class ownership structures we hypothesize that the use of debt alleviates the conflict between shareholder classes by balancing the power of controlling insiders we document that dual class firms have higher leverage and a greater propensity to issue private debt they also more frequently use cash sweeps and performance based covenants dual class firms with greater agency conflicts and a greater need to access the capital market appear to rely more extensively on debt these findings are consistent with controlling insiders bonding against the agency costs associated with dual class ownership the governance role of debt is further corroborated by the valuation effect of debt for dual class companies private debt issuances trigger greater positive market reactions to the inferior dual class stock in relation to both the superior dual class stock and a matched sample of single class firms further leverage attenuates the previou

does competition from private surgical centres improve public hospitals performance evidence from the english national health service abstract this paper examines the impact of a government programme which facilitated the entry of for profit surgical centres to compete against incumbent national health service hospitals in england we examine the impact of competition from these surgical centres on the efficiency measured by pre surgery length of stay for hip and knee replacement patients and case mix of incumbent public hospitals we exploit the fact that the government chose the broad locations where these surgical centres independent sector treatment centres or istcs would be built based on local patient waiting times not length of stay or clinical quality to construct treatment and control groups that are comparable with respect to key outcome variables of interest using a difference in difference estimation strategy we find that the government facilitated entry of surgical centres led to shorter pre surgery length of stay at nearby public hospitals however these new entrants took on healthier patients and left incumbent hospitals treating patients who were sicker this paper highlights a potential trade off that policymakers face when they promote competition from private for profit firms in markets for the provision of public services

investment crowding out firm level evidence from northern germany michalek j ciaian p and kancs d a investment crowding out firm level evidence from northern germany regional studies the main objective of this paper is to estimate the extent to which firm investment is substituted crowded out by investment support policies granted under the european union rural development programme rdp the empirical analyses employed the difference in difference propensity score matching approach which allows several important sources of bias to be addressed such as selection bias simultaneity bias and functional form misspecification from which many previous studies suffer using panel data of 1333 firms from the schleswig holstein region in germany it is found that the crowding out effect of the rdp is close to 100 implying that firms use public support to substitute for private investments furthermore no evidence was found that due to the rdp programme support firms would have brought forward their investments planned originally for a later period rejecting t

agglomeration and clusters tools and insights from coagglomeration patterns geographic clusters have received first order policy attention despite our limited academic knowledge about them i explain how coagglomeration patterns of industries can inform the analysis of clusters by allowing us to better delineate them to explore the causal mechanisms underlying them and to more finely assess their impact on various economic outcomes

the consequences of child soldiering abstract little is known about the impacts of military service on human capital and labor market outcomes due to an absence of data as well as sample selection recruits are self selected screened and selectively survive we examine the case of uganda where rebel recruitment methods provide exogenous variation in conscription economic and educational impacts are widespread and persistent schooling falls by nearly a year skilled employment halves and earnings drop by a third military service seems to be a poor substitute for schooling psychological distress is evident among those exposed to severe war violence and is not limited to ex combatants

chief executive officer equity incentives and accounting irregularities this study examines whether chief executive officer ceo equity based holdings and compensation provide incentives to manipulate accounting reports while several prior studies have examined this important question the empirical evidence is mixed and the existence of a link between ceo equity incentives and accounting irregularities remains an open question because inferences from prior studies may be confounded by assumptions inherent in research design choices we use propensity score matching and assess hidden omitted variable bias within a broader sample in contrast to most prior research we do not find evidence of a positive association between ceo equity incentives and accounting irregularities after matching ceos on the observable characteristics of their contracting environments instead we find some evidence that accounting irregularities occur less frequently at firms where ceos have relatively higher levels of equity incentives

endogeneity bias modeling using observables this paper proposes an alternative solution to the endogeneity problem by explicitly modeling the joint interaction of the endogenous variables and the unobserved causes of the dependent variable as a function of additional observables we derive identification of the parameters develop an estimator and establish its consistency and asymptotic normality

industrial governance structures innovation strategies and the case of japan sectoral or cross national comparative analysis in comparative research on industrial policy strategies attention has shifted from national level variables to sectoral variables in both the description and the explanation of policy the sectoral literature however lacks analytic focus and has provided little systematic insight into the causes of cross sectoral variance in governance structures and policy strategies based on recent contributions to the economics and sociology of formal organizations this article attempts to sharpen the concept of industrial sector and to provide a rationale for why sectoral structures and strategies vary next it develops a synthetic explanatory framework that combines sectoral analysis and national domestic structuralism in order to account for industrial innovation strategies in advanced capitalist countries in the final section the fruitfulness of this approach is illustrated by developing a new account of japan s success and failure in industrial innovation an account that overcomes the contradictions among the main alternatives offered in the past the key objective of the article however is to develop a new set of theoretical hypotheses for cross national research not a rigorous empirical test of its main propositions

growth waves systemic openness and protectionism there is a distinctively repetitive quality about trade policy problems domestic economic growth slows producers seek protection against foreign competitors and national decision makers raise barriers to trade while at the same time criticizing their counterparts in other governments for engaging in similar practices because trade is one of the more important topics in international and comparative political economy and because this scenario has played itself out more than a few times it is not surprising that a number of theorists have sought to model the underlying processes thought to produce movements toward and away from protectionism by now a variety of different types of approaches ranging from the cognitive to the systemic have been tried systemic structure ideas and ideology surplus capacity business cycles and shifts in elite orientation and domestic coalitions in response to external crises have been emphasized as principal theoretical foci our position is that the different levels of analysis and alternative foci all have merit and utility what they lack is an appreciation for the underlying systemic processes that link together these various facets of the political economy we seek to develop a theoretical argument that explicates these underlying processes the argument centers on recurring growth waves characterized in alternating pattern by the ascent of system leaders and the subsequent successful attempt of technological followers to catch up with the leaders the downturns of the growth waves produce conditions favoring protectionism but we contend the form and the intensity of protectionism that are likely to be produced will depend on which of the two types of growth waves is in progress ascent waves are characterized by the emergence of new technological leaders and a consequent increase in the gap between the leaders and the technological followers during the periods of structural transition and intense

mobile phone coverage and producer markets evidence from west africa mobile phone coverage has expanded considerably throughout the developing world particularly within sub saharan africa existing evidence suggests that increased access to information technology has improved agricultural market efficiency for consumer markets and certain commodities but there is less evidence of its impact on producer markets building on the work of aker 2010 this paper estimates the impact of mobile phone coverage on producer price dispersion for three commodities in niger the results suggest that mobile phone coverage reduces spatial producer price dispersion by 6 percent for cowpea a semi perishable commodity these effects are strongest for remote markets and during certain periods of the year the introduction of mobile phone coverage has no effect on producer price dispersion for millet and sorghum two staple grains that are less perishable and are commonly stored by farmers there are no impacts of mobile phone coverage on traders gross margins or producer price levels but mobile phone coverage is associated with a reduction in the intra annual price variation for cowpea these results are potentially explained by the fact that farmers engage in greater storage for storable commodities such as millet and sorghum

computers skills and wages computer technology is most prominently used by skilled high wage workers this suggests that computer use requires skills to take full advantage of the possibilities which are particularly present among relatively skilled workers this article develops a simple technology adoption model showing that the decision to adopt computer technology depends on i the tasks to be performed ii the level of skill or education and iii the level of wages applying this model to british data it is shown that the effect of wages and particular tasks on computer adoption is larger than the effect of skills on adoption the estimates suggest that in britain computer use is likely to be a matter of cost efficiency and not so much of workers skills

the effect of male migration on employment patterns of women in nepal what is the impact of male migration on the labor market behavior of women in nepal the instrumental variable full information maximum likelihood method is applied to data from the 2004 nepal household survey to account for unobserved factors that could simultaneously affect men s decision to migrate and women s decision to participate in the labor market the results indicate that male migration has a negative impact on the level of the labor market participation by women in the migrant sending household there is evidence of substantial heterogeneity based on both observable and unobservable characteristics in the impact of male migration the findings highlight the important gender dimension of the impact of predominantly male migration on the well being of sending households strategies for economic development in nepal should take into account such gender aspects of the migration dynamics

reconciling conflicting evidence on the performance of propensity score matching methods there is a long standing debate in the literature over whether social programs can be reliably evaluated without a randomized experiment this paper summarizes results from a larger paper smith and todd 2001 that uses experimental data combined with nonexperimental data to evaluate the performance of alternative nonexperimental estimators the impact estimates based on experimental data provide a benchmark against which to judge the performance of nonexperimental estimators our experimental data come from the national supported work nsw demonstration and the nonexperimental data from the current population survey cps and the panel study of income dynamics psid these same data were used in influential papers by robert lalonde 1986 james heckman and joseph hotz 1989 and rajeev dehejia and sadek wahba 1998 1999 we focus on a class of estimators called propensity score matching estimators which were introduced in the statistics literature by paul rosenbaum and donald rubin 1983 traditional propensity score matching methods pair each program participant with a single nonparticipant where pairs are chosen based on the degree of similarity in the estimated probabilities of participating in the program the propensity scores more recently developed nonparametric matching estimators described in heckman et al 1997 1998a b use weighted averages over multiple observations to construct matches we apply both kinds of estimators in this paper heckman et al 1997 1998a b evaluate the performance of matching estimators using experimental data from the u s national job training partnership act jtpa study combined with comparison group samples drawn from three sources they show that data quality is a crucial ingredient to any reliable estimation strategy specifically the estimators they examine are only found to perform well in replicating the results of the experiment when they are applied to comparison group data satisfying the following criteria i the same data sources i e the same surveys or the same type of administrative data or both are used for participants and nonparticipants so that earnings and other characteristics are measured in an analogous way ii participants and nonparticipants reside in the same local labor markets and iii the data contain a rich set of variables relevant to modeling the program participation decision if the comparison group data fails to satisfy these criteria the performance of the estimators diminishes greatly more recently dehejia and wahba 1998 1999 have used the nsw data also used by lalonde to evaluate the performance of propensity score matching methods including pairwise matching and caliper matching they find that these simple matching estimators succeed in closely replicating the experimental nsw results even though the comparison group data do not satisfy any of the criteria found to be important in heckman et al 1997 1998a from this evidence they conclude that matching approaches are generally more reliable than traditional econometric estimators in this paper we reanalyze the nsw data in an attempt to reconcile the conflicting findings smith department of economics university of western ontario social science centre london on n6a 5c2 canada and nber todd department of economics university of pennsylvania 3718 locust walk philadelphia pa 19104 and nber versions of the paper that is the source for this paper have been presented at a 2000 meeting of the institute for research on poverty in madison wisconsin at the western research network on employment and training summer workshop august 2000 at the canadian international labour network meetings september 2000 and at the university of north carolina we thank james heckman for comments on this paper and we thank robert lalonde for comments and for providing us with the data from his 1986 study we thank rajeev dehejia for providing us with information helpful in reconstructing the samples used in the dehejia and wahba 1998 1999 studies jingjing hsee and miana plesca provided excellent research assistance

the economic consequences of unwed motherhood using twin births as a natural experiment social scientists have long concluded that premarital childbearing exacerbates problems of both poverty and family instability out of wedlock and adolescent childbearing may reduce a mothers educational attainment lower the probability of her eventual marriage increase her probability of welfare recipiency and decrease family income the authors use an exogenous fertility event the birth of twins to estimate the economic effects of unplanned births the approach compares the economic outcomes of women experiencing premarital twin first births to those experiencing premarital single first births in the attempt to identify the consequences of an unplanned birth upon womens future fertility and marital decisions education labor force participation labor earnings welfare receipt and poverty status 1970 and 1980 us census micro data are used to identify twin births to unmarried women analysis found large short term effects of unplanned births on labor force participation poverty and welfare recipiency among unwed mothers but not among married mothers furthermore most adverse economic effects of unplanned motherhood dissipate over time for whites but larger and more persistent negative effects weigh upon black unwed mothers

the wto trade effect this paper reexamines the gatt wto membership efiect on bilateral trade ows using nonparametric methods including pair matching permutation tests and a rosenbaum 2002 sensitivity analysis together these methods provide an estimation framework that is robust to misspeciflcation biases allows general forms of heterogeneous treatment efiects and addresses potential hidden selection biases this is in contrast to most conventional parametric studies on this issue our results suggest large gatt wto trade promoting efiects robust to various restricted matching criteria alternative indicators for gatt wto involvement different matching methodologies non random incidence of positive trade ows and inclusion of multilateral resistance terms

heterogeneous sports participation and labour market outcomes in england based on a unique composite dataset measuring heterogeneous sports participation labour market outcomes and local facilities provision this article examines for the first time the association between different types of sports participation and employment and earnings in england clear associations between labour market outcomes and sports participation are established through matching estimation while controlling for some important confounding factors the results which are supplemented and supported by a formal sensitivity analysis suggest a link between different types of sports participation to initial access to employment and then higher income opportunities with ageing however these vary between the genders and across sports specifically the results suggest that team sports contribute most to employability but that this varies by age across genders and that outdoor activities contribute most towards higher incomes

using contingent valuation to explore willingness to pay for renewable energy a comparison of collective and voluntary payment vehicles abstract this study uses a split sample dichotomous choice contingent valuation survey of 1574 u s residents to explore willingness to pay wtp for renewable energy under collective and voluntary payment vehicles and under government and private provision of the good we also evaluate the impact of participation expectations on stated wtp we find some evidence that when confronted with a collective payment mechanism respondents state a somewhat higher wtp than when voluntary payment mechanisms are used similarly private provision of the good elicits a somewhat higher wtp than does government provision we also find that contingent valuation responses are strongly correlated with expectations for the wtp of others our results shed light on strategic response behavior and the incentive compatibility of different cv designs and offer practical insight into u s household preferences for how to support renewable energy

selection on observed and unobserved variables assessing the effectiveness of catholic schools in this paper we measure the effect of catholic high school attendance on educational attainment and test scores because we do not have a good instrumental variable for catholic school attendance we develop new estimation methods based on the idea that the amount of selection on the observed explanatory variables in a model provides a guide to the amount of selection on the unobservables we also propose an informal way to assess selectivity bias based on measuring the ratio of selection on unobservables to selection on observables that would be required if one is to attribute the entire effect of catholic school attendance to selection bias we use our methods to estimate the effect of attending a catholic high school on a variety of outcomes our main conclusion is that catholic high schools substantially increase the probability of graduating from high school and more tentatively attending college we find little evidence of an effect on test scores

evaluating the econometric evaluations of training programs with experimental data this paper takes the results of an employment and training program thatwas run as a field experiment in which the participants were randomlyassigned into a treatment or a control group and compares these results to the estimates that might have been produced by an econometrician who evaluated the program using the same econometric procedures that have been used in the program evaluation literature this comparison shows that many of these econometric procedures fail toreplicate the experimentally determined results and suggests that researchers should be aware of the potential for specification errorsin other nonexperimental evaluations copyright 1986 by american economic association

negative publicity and catholic schools i introduction catholic education makes up a large part of the united states k 12 educational system catholic schools educate over one third of all private school students more elementary and secondary students than all other religious schools combined national center for education statistics nces 2007 however catholic education is becoming less prevalent between 1990 and 2007 the number of catholic schools decreased by 14 from 8 719 to 7 498 while enrollment declined by 7 from 2 498 870 to 2 320 651 1 the mainstream media has covered this trend beginning with closings in the early 1990s foderaro 1990 private schools enroll 11 of elementary and secondary school students 39 of private school students enroll in catholic schools 2 catholic schools historically have served a predominantly urban minority population with some success research generally finds modest gains in educational attainment particularly for minority students e g altonji et al 2005 evans and schwab 1995 neal 1997 there is evidence that catholic schools raise student academic achievement and reduce adolescent risky behaviors figlio and ludwig 2000 figlio and stone 2000 3 the current decline in catholic schooling reflects diminished opportunities for students to enroll in alternatives to public schools this decline is particularly troubling for the low income urban minority students who have particularly benefited from catholic schools in the past neal 1997 the decline in private schooling options also lowers the level of competition among schools the decrease in competition may worsen the outcomes of public school students hoxby 1994 we consider potential explanations for the decline in catholic schooling in the united states changing demographics changing income levels and public awareness of sexual abuse and allegations immigration into and within the united states particularly of the traditionally catholic hispanic population likely affected demand for catholic schooling o keefe 1996 suggests that falling income per capita near existing catholic schools led to school closings further the negative publicity from the sexual abuse crisis in the catholic church may have impacted the availability of and demand for catholic schooling using diocese level panel data on catholic schooling we empirically examine the importance of each of these factors we develop two proxy measures of negative publicity based on the press coverage and on plausibly public notifications of abuse allegations we find that negative publicity is associated with a reduction in the availability of catholic schools however its effect is small allegations related to the abuse cases account for about 5 of the decline in catholic schools changing demographics particularly increases in the hispanic population explain a larger proportion of the current decline in catholic schooling ii an overview of catholic school enrollment and catholic schools in the united states the catholic church is organized into dioceses and archdioceses each administered by a bishop or archbishop there are 175 of these in the united states with each state and the district of columbia having at least one dioceses for the most part follow county lines texas with 14 is the state that has the most dioceses the average state has approximately 3 5 dioceses catholic schools tend to be operated with financial backing from the local diocese in combination with revenue from tuition and direct donations diocesan support ranges from a low of around 5 of school funding coming from dioceses in the south and west to a high of about 50 in the midwest gero and meitler 2003 figure 1 presents the percent of school aged children enrolled in catholic schools and the number of catholic schools for 1990 to 2007 4 the number of catholic schools declined in the early 1990s the decline slowed in the mid 1990s and accelerated again around 2004

causes of the eu ets price drop recession cdm renewable policies or a bit of everything new evidence the price of eu allowances euas in the eu emissions trading scheme eu ets fell from almost 30 tco2 in mid 2008 to less than 5 tco2 in mid 2013 the sharp and persistent price decline has sparked intense debates both in academia and among policy makers about the decisive allowance price drivers in this paper we examine whether and to what extent the eua price drop can be justified by three commonly identified explanatory factors the economic recession renewable policies and the use of international credits capitalizing on marginal abatement cost theory and a broadly extended data set we find that only variations in economic activity and the growth of wind and solar electricity production are robustly explaining eua price dynamics contrary to simulation based analyses our results point to moderate interaction effects between the overlapping eu ets and renewable policies the bottom line however is that 90 of the variations of eua price changes remains unexplained by the abatement related fundamentals together our findings do not support the widely held view that negative demand shocks are the main cause of the weak carbon price signal in view of the new evidence we evaluate the eu ets reform options which are currently discussed

supply chains and economic development insights from the indian dairy sector with almost three quarters of the labor force depending on agriculture in india kick starting agricultural growth is considered crucial for pro poor development more specifically dairy production which is labor intensive but does not heavily rely on access to land is generally expected to offer better prospects for income growth to the poorest among rural households however most policies aimed at increasing dairy production are based on ad hoc observations with hardly any micro level evidence using a unique primary dataset on 1000 rural households in andhra pradesh this paper investigates the dairy production system addressing three main research questions first we look at the typical profile of a dairy farmer and we find that both family traditions in dairy and owning even a small piece of land play a role in determining participation in dairy while land size does not matter second we show that dairy production is strongly and positively associated with improvement in rural livelihoods in terms of income per capita but that this positive relation only holds for larger dairy farms in a third step we look at the determinants of farm growth and we find that households having higher shares of graded dairy animals have grown more after 2005

the countervailing effects of competition on public goods provision when bargaining inefficiencies lead to bad outcomes political competition is widely recognized as a mediator of public goods provision through its salutary effect on incumbents electoral incentives we argue that political competition additionally mediates public goods provision by reducing the efficiency of legislative bargaining these countervailing forces may produce a net negative effect in places with weak parties and low transparency typical of many young democracies we provide evidence of a robust negative relationship between political competition and local public goods using panel data from mali tests of mechanisms corroborate our interpretation of this relationship as evidence of legislative bargaining inefficiencies to explore the generalizability of these findings we analyze cross country panel data and show that political competition leads to better worse public goods provision under high low levels of party system institutionalization the paper sheds light on why political competition is only selectively beneficial and underscores the importance of considering both the electoral and legislative arenas

catholic schooling and further education abstract using new estimation methods and data i find that catholic schooling substantially increases years of schooling by 0 42 to 0 47 the estimates are robust to various specifications that account for potential selection bias

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

disaster aid and preferences the long run impact of the tsunami on giving in sri lanka summary do natural disasters produce effects on preferences of victims in the long run we test the impact of the tsunami shock on generosity of a sample of sri lankan affected unaffected microfinance borrowers seven years after the event specifically we test the effect of the shock at the extensive margin by comparing damaged with non damaged individuals in terms of giving and expected giving in a dictator game moreover at the intensive margin we compare the participants based on the amount of damage experienced and recovery aid received the advantage of this last comparison is that differences in observables between the groups are minimized we reduce further identification problems by selecting a random sample of damaged and non damaged borrowers belonging to the same microfinance organization who are therefore likely to share some important common traits that are usually unobservable to researchers we complete our identification strategy with weighted least squares instrumental variable estimates and a sensitivity analysis on the exogeneity assumption the main findings of the paper support the hypothesis that the shock affects participants preferences in the long run first the tsunami negatively affects generosity at the extensive margin as those who suffered at least one damage give and expect less than those who did not second while large recovery assistance does not directly affect giving and expected giving it increases especially the latter indirectly i e when interacted with the number of damages our results reconcile that part of the literature showing evidence of natural shocks having a detrimental effect on social preferences fleming chong alberto bejarano 2011 cassar grosjean whitt 2013 with that supporting instead a positive link solnit 2009 whitt wilson 2007 cassar healy von kessler 2011 furthermore since our study focuses on the long run impact of a natural disaster previous results on short run effects are not necessarily inconsistent with ours

sensitivity to exogeneity assumptions in program evaluation in many empirical studies of the effect of social programs researchers assume that conditional on a set of observed covariates assignment to the treatment is exogenous or unconfounded aka selection on observables often this assumption is not realistic and researchers are concerned about the robustness of their results to departures from it one approach e g charles manski 1990 is to entirely drop the exogeneity assumption and investigate what can be learned about treatment effects without it with unbounded outcomes and in the absence of alternative identifying assumptions there are no restrictions on the set of possible values for average treatment effects this does not mean however that all evaluations are equally sensitive to departures from the exogeneity assumption in this paper i explore an alternative approach developed by paul rosenbaum and donald rubin 1983 where the assumption of exogeneity is explicitly relaxed by allowing for a limited amount of correlation between treatment and unobserved components of the outcomes the starting point of the sensitivity analysis is the assumption that the exogeneity assumption is satisfied only conditional on an additional unobserved covariate making assumptions about the effect of the unobserved covariate on the outcome and its correlation with the treatment i trace out the set of possible values for the treatment effect of interest by considering a sufficiently large set of possible correlations with outcomes and treatment one can recover the bounds on the treatment effect derived by manski 1990 the approach here in the spirit of rosenbaum and rubin 1983 and rosenbaum 1995 is to allow only a limited amount of correlation and to judge the sensitivity of average treatment effect estimates to such correlations there are two novel features of the proposed analysis first rather than formulate the sensitivity in terms of coefficients on the unobserved covariate the sensitivity results are presented in terms of partial r values which may be easier to interpret second the partial r values of the unobserved covariates are compared to those for the observed covariates in order to facilitate judgments regarding the plausibility of values necessary to substantially change results obtained under exogeneity the proposed sensitivity analysis is conceptually related to the practice of assessing sensitivity of estimates by comparisons with results obtained by discarding one or more observed covariates james heckman and v joseph hotz 1989 rajeev dehejia and sadek wahba 1999 jeffrey smith and petra todd 2001 the attraction of the sensitivity analysis is that it is more directly relevant one is not interested in what would have happened in the absence of covariates actually observed but in biases that are the result from not observing all relevant covariates

long waves technological innovation and relative decline the popularity of kondratieff long waves fluctuates according to the economic climate periods of slow growth help make long wave explanations more attractive while their popularity may oscillate the evidence associated with the existence of long waves continues to be disputed a review of the pertinent theoretical literature suggests that one reason for the disagreements about the existence of long waves is that much of the available evidence does not correspond as closely as it might to the theoretical foci a new data series one based on leading sector production growth rates from 1760 to 1985 is developed to remedy this lack of correspondence the appropriate analysis of this series requires that particular attention be paid to the rise and relative decline of the world economy s lead state the empirical outcome provides a close match to the long wave chronology developed by joseph schumpeter simon kuznets and j j van duijn while this approach falls short of bringing closure to many of the theoretical and empirical questions concerning long waves it does establish a solid empirical foundation for further analyses the article concludes with some observations on the long wave implications for the relative economic decline of britain in the nineteenth century and the united states in the twentieth century

willingness to pay for carbon offset certification and co benefits among high flying young adults in the uk voluntary carbon offsets represent a growing share of the carbon market as a whole and have the potential to contribute to meeting greenhouse gas emissions targets and reducing anthropogenic climate change certain offset project types may also deliver co benefits including safeguarding or promoting biodiversity supporting human development and poverty reduction and enabling market and technology development in low carbon sectors these co benefits might encourage consumers to participate in the voluntary offset market depending on their effects both on consumers willingness to pay wtp for offsets and on implementation costs however the offset market is not yet sufficiently developed to give a clear indication of consumer wtp for offsets with varying attributes this exploratory stated preference study therefore uses a choice experiment to estimate wtp for certified and uncertified offsets with or without these specific co benefits in an aviation context it is to the best of our knowledge the first to do so our results suggest that uptake of voluntary offsets may be encouraged by investing in projects with co benefits and by emphasising those co benefits to consumers they also suggest that certification regimes will add value to offsets helping compensate for increased costs provided that consumers are made fully aware of them

gender agricultural production and the theory of the household virtually all models of the household assume that the allocation of resources is pareto efficient within many african households agricultural production occurs on many plots controlled by different members of the household pareto efficiency implies that factors should be allocated efficiently across these plots i find in contrast that plots controlled by women are farmed much less intensively than similar plots within the household controlled by men the estimates imply that about 6 percent of output is lost because of inefficient factor allocation within the household the paper suggests a new approach to modeling intrahousehold allocation consistent with the empirical results

long waves and economic growth a critical appraisal no one who has examined the dynamics of capitalist economies over long historical periods can doubt that they experience significant long term variations in their aggregate performance the question is whether these long term variations are more than the outcome of a summation of random events and further whether they exhibit recurrent temporal regularities that are sufficiently well behaved to call them long waves in recent years there has been a strong resurgence of interest in such long term movements since their existence could provide a coherent explanation for the poor performance of capitalist economies over the past decade we do not attempt herein to examine the historical evidence for long cycles we have in fact examined this evidence and find it unconvincing although historical data might conceivably lend some plausibility to the notion of long cycles in prices we remain at present sceptical of the case that has so far been made for their presence in real phenomena that is in aggregate output or employment what we offer here instead consistent with our present scepticism is an attempt to examine the economic logic of long waves more specifically we ask what conditions would need to be fulfilled in order for technological innovation to generate long cycles of the periodicity postulated by n d kondratiev and his disciples it is our view that such a theory which might account for the presence of long cycles in some real economic variable would have to fulfill a set of logically interdependent requirements we discuss these requirements under the four categories of causality timing economywide repercussions and recurrence 1 causality

an experimental test of warm glow giving abstract this paper reports the results of an experimental test of the warm glow hypothesis a participant is presented with the opportunity to contribute from her own endowment to a charity of choice the experiment is designed so that a pure altruist has no incentive to donate the amount the designated charity will receive is preset any contribution by the participant crowds out dollar for dollar giving by the proctor we find that participants on average donated 20 of their endowments and that approximately 57 of the participants made a donation

financial asset holdings and political attitudes evidence from revolutionary england the english parliament s struggle for supremacy against monarchical dictatorship during the civil war 1642 1648 was crucial for the establishment of representative government yet its lessons continue to be debated i exploit novel data on individual mps drawn from 1 842 biographies to show that the conflict was over overseas interests and other factors over which the executive enjoyed broad constitutional discretion rather than over domestic property rights i further exploit the coincidence of individual mps ability to sign legally binding share contracts with novel share offerings by overseas companies to measure the effect of overseas share investment on their political attitudes i show that overseas shareholding pushed moderates lacking prior mercantile interests to support reform i interpret the effect of financial assetholding as allowing new investors to exploit emerging economic opportunities overseas aligning their interests with traders by consolidating a broad parliamentary majority that favored reform the introduction of financial assets also broadened support for the institutionalization of parliamentary supremacy over dictatorial rule jel codes o10 g11 f10 k00 n23 p10

the effects of child bearing on married women s labor supply and earnings using twin births as a natural experiment we use exogenous variations in fertility due to twin births to measure the impact of an unplanned child on married women s labor supply and earnings although the overall effects of an unplanned birth on labor supply are small we find significant effects in the years immediately following the unplanned birth especially in 1970 we estimate that declining fertility explains between 6 and 13 percent of the increase in married women s labor supply between 1970 and 1980 twin births are also associated with a substantial short run loss in earnings this effect persists longer than the labor supply effects though it does eventually disappear

willingness to pay for curbside recycling with detection and mitigation of hypothetical bias in this article we estimate willingness to pay for curbside recycling using a unique data set we also test for and detect significant hypothetical bias using stated and revealed preference data a short scripted cheap talk statement is used to mitigate the bias and provide more efficient estimates of the welfare impacts of curbside recycling programs copyright 2003 oxford university press

the structure of motivation for contingent values a case study of lake water quality improvement abstract critics of the contingent valuation cv method have argued that individuals apply noneconomic motives in responding to cv questions implying that elicited values are not valid measures of the economic benefit of environmental improvement this study examines the role of such motives by using measures of attitude and motive strength to interpret willingness to pay wtp values for a set of nested environmental goods with potential use and nonuse benefits motivational structure is found to be more complex than suggested by the simple distinction between valid economic theoretic and noneconomic motives social motivations possibly associated with the benefit of contributing to a public good rather than the benefits of the good itself are potentially relevant to the wtp decision but do not give rise to separable values the strength of perceived personal responsibility for provision of the good is significantly associated with wtp but also with the theoretically desirable property of enhanced scope sensitivity wtp is not found to be associated with the extent to which the individual feels under some general moral obligation to contribute to good causes motives arising from ethical concerns for the environment and altruism are also potentially relevant to wtp but are closely related to underlying motives associated with existence and personal use values respectively it is suggested that the cv debate should be informed by further empirical investigation of the extent to which motives for wtp can be treated as separable

can risk averse households make risky investments the role of trust in others in this paper using data from the survey on health ageing and retirement in europe share 2006 and 2013 waves we illustrate the link between individuals attitudes to financial risk combined with their willingness to trust others and their investments in risky assets individuals who display either risk tolerance alone or to a lesser extent risk aversion and trust more frequently decide to buy risky assets the comparison between scandinavian and mediterranean countries indicates that trust plays qualitatively different roles depending on the prevailing combination of risk attitude and trust in the area being studied

are they efficient in the middle using propensity score estimation for modeling middlemen in indian corporate corruption corrupt regulatory environment encourages firms to deploy middlemen for speedy and assured acquisition of different services from regulatory agencies using a world bank dataset of 2210 indian manufacturing firms this article examines how firms with middlemen deal with corrupt governmental agencies for its operational efficiency our results demonstrate that deployment of middlemen by the firms is often accompanied by a substantial increase in operational delay relatively trigger more consumption of senior management s time on regulatory disentanglement enhance the likelihood tendency to pay bribe and likely to face more court cases as a means of restitution of legal rights as firm specific attributes may contaminate our preliminary results we utilized the propensity score framework to examine relationships among variables of interests our study contributes to the inconspicuous part of the corruption literature by attempting to present a comprehensive but indirect assessment of the functions of middlemen that predominantly remained unattended except some scattered descriptive case based anecdotal presentations

further tests of entreaties to avoid hypothetical bias in referendum contingent valuation abstract over estimation of willingness to pay in contingent markets has been attributed largely to hypothetical bias one promising approach for avoiding hypothetical bias is to tell respondents enough about such bias that they self correct for it a script designed for this purpose by cummings and taylor was used in hypothetical referenda that differed in payment amount in comparisons with behavior observed in otherwise identical real payment referenda the script worked remarkably well at higher payment levels dropping the likelihood of a yes vote to the level obtained in separate sample real referenda but less well at a lower payment level the repeated success of the script at higher payment amounts is a clear sign that additional research is warranted research that will bring us a more complete understanding of how the entreaty works this research may need to explore its workings at the individual respondent level

land tenure differences and investment in land improvement measures theoretical and empirical analyses this article develops a theoretical framework to examine the relationship between land tenure arrangements and households investment in soil improving and conservation measures it then analyzes this relationship with a multivariate probit model based on detailed plot level data from villages in the brong ahafo region of ghana a major hypothesis tested is that investment in productivity enhancing and conservation techniques are influenced by land tenure arrangements the theoretical analysis and empirical results generally reveal that land tenure differences significantly influence farmers decisions to invest in land improving and conservation measures the findings also show that tenure security does affect farm productivity

children and their parents labor supply evidence from exogenous variation in family size although theoretical models of labor supply and the family are well developed there are few credible estimates of key empirical relationships in the work family nexus this study uses a new instrumental variable the sex composition of the first two births in families with at least two children to estimate the effect of additional children on parents labor supply in the united states instrumental variables estimates using the sex mix are substantial but smaller than the corresponding ordinary least squares ols estimates moreover unlike the ols estimates the female labor supply effects estimated using sex mix instruments appear to be absent among more educated women and women with high wage husbands we also find that married women who have a third child reduce their labor supply by as much as women in the full sample while there is no relationship between wives child bearing and husbands labor supply excerpt

incentives and the supply of effective charter schools charter school funding is typically set by formulas that provide the same amount for all students regardless of advantage or need in this paper i present evidence that this policy skews the distribution of students served by charters towards low cost populations by influencing where charter schools decide to open and whether they survive i develop and estimate an empirical model of charter school supply and competition to evaluate the effects of funding policies that aim to correct these incentives to do this i recover estimates of cost differentials across student populations by linking charter school effectiveness at raising student achievement with unique records of charter school expenditures gathered from florida i then leverage revealed preference with the exit and location choices of charter schools in an entry game to uncover how charter schools respond to competitive and financial incentives the results indicate that a cost adjusted funding formula would significantly increase the share of charter schools serving disadvantaged students with little reduction in the aggregate effectiveness of the sector

using ex ante approaches to obtain credible signals for value in contingent markets evidence from the field while contingent valuation remains the only option available for measurement of total economic value of nonmarketed goods the method has been criticized due to its hypothetical nature we analyze field experimental data to evaluate two ex ante approaches to attenuating hypothetical bias directly comparing value statements across four distinct referenda hypothetical cheap talk consequential and real our empirical evidence suggests two major findings hypothetical responses are significantly different from real responses and responses in the consequential and cheap talk treatments are statistically indistinguishable from real responses we review the potential for each method to produce reliable results in the field

the demand for climate protection empirical evidence from germany abstract an experiment designed to find the real demand for climate protection was conducted among a sample of the residential population in mannheim germany participants were offered the opportunity to contribute to climate protection by purchasing european union allowances which were then withdrawn from the european emissions trading scheme our experiment showed a median willingness to pay wtp of zero and a mean wtp of approximately 12 t co 2

nonparametric bounds on treatment effects assume that each member of a population is characterized by values for the variables ya yb z x here x is a vector describing a person and z is a binary variable indicating which of two treatments this person receives the treatments are labelled a and b the variables ya and yb are scalar measures of the outcomes of the two treatments for example a cancer patient might be treated by a drug therapy or b surgery the relevant outcome y might be life span following treatment an unemployed worker might be given a vocational training or b job search assistance here the relevant outcome might be labor force status following treatment assume that a random sample is drawn and that one observes the realizations of z x and of the outcome under the treatment received thus ya is observed if treatment a is received but is a latent variable if treatment b is received similarly yb is either observed or latent suppose that one wants to learn the difference in expected outcome if all persons with attributes x were assigned to treatment a or b this treatment effect is

is low priced primary care bad for quality evidence from australian general practice we examine whether patients perceptions of general practitioner gp care varies by the price paid for consultations australian consumer survey data from 2275 individuals were used to analyse the relationship between price and patient experience of gp care using both standard models for count data and a latent class model that distinguishes between patients with high and low quality experiences we find no evidence that lower prices have a negative impact on patients perceptions of gp quality nevertheless some patient characteristics such as age gender and health status play a significant role in quality of care perceptions the results show that australian patients have not had to compromise gp quality as expressed in terms of patient experience when seeking low priced care this supports the view that there are sufficient checks and balances on the gp sector in australia to ensure positive patient experiences even for low cost gp consultations

informal care and long term labor market outcomes in this paper we estimate long run effects of informal care provision on female caregivers labor market outcomes up to eight years after care provision we compare a static version where average effects of care provision in a certain year on later labor market outcomes are estimated to a partly dynamic version where the effects of up to three consecutive years of care provision are analyzed our results suggest that there are significant initial negative effects of informal care provision on the probability to work full time the reduction in the probability to work full time by 4 percentage points or 2 4 5 0 if we move from point to partial identification is persistent over time short run effects on hourly wages are zero but we find considerable long run wage penalties

household inequality entrepreneurial dynamism and corporate financing economic theories provide conflicting hypotheses on how wealth inequality affects entrepreneurial dynamism to empirically investigate its impact we construct local measures of household wealth inequality based on financial rents home equity and 1880 farmland we identify its effects on entrepreneurship by instrumenting it with land distribution under the 1862 homestead act or us states removal of death taxes wealth inequality decreases firm entry and exit and the proportion of high tech businesses across metropolitan statistical areas there is also less redistribution into public goods supportive of entrepreneurship such as schooling and the judiciary income per capita consequently grows more slowly

estimating the distortionary effects of ethnic quotas in singapore using housing transactions abstract desegregation is a key policy issue in many countries i investigate a residential desegregation program in singapore the ethnic housing quotas i show that choice restrictions imposed on apartment blocks above the quota limits constrained could have distortionary effects causing price and quantity differences for constrained versus unconstrained blocks i test these predictions by hand matching more than 500 000 names in the phonebook to ethnicities to calculate ethnic proportions at the apartment block level i can then investigate differences for constrained and unconstrained blocks close to the quota limits and test for sorting around the limits i find that price differences are between 3 and 5 quantity effects are economically significant translating to longer time on market durations selection cannot fully explain these results my results point to challenges in achieving desegregation using quantity restrictions

finishing high school and starting college do catholic schools make a difference in this paper we consider two measures of the relative effectiveness of public and catholic schools finishing high school and starting college these measures are potentially more important indicators of school quality than standardized test scores in light of the economic consequences of obtaining more education single equation estimates suggest that for the typical student attending a catholic high school raises the probability of finishing high school or entering a four year college by thirteen percentage points in bivariate probit models we find almost no evidence that our single equation estimates are subject to selection bias

using experiments to evaluate performance standards what do welfare to work demonstrations reveal to welfare reformers this paper examines how experimental demonstrations can be used to inform planners about the efficacy of social programs in light of a performance standard the problem is illustrated by considering the situation faced by state governments attempting to design programs to meet the new federal welfare to work standards data from experimental evaluations alone allow only limited inferences about the labor market outcomes of welfare recipients combined with prior information on the selection process however these data are informative suggesting either that the long run federal requirements cannot be met or that these standards will only be met under special circumstances

private or public school advantage evidence from 40 countries using pisa 2012 mathematics abstractit is known that in most countries private school students outperform students in public schools in international assessments however the empirical literature recognizes that assessing the true effect of private school attendance requires addressing selection and sorting issues on both observabland unobservables the existing empirical evidence on the private school effect mostly covers oecd and latin american countries with little evidence on other parts of the world there is recent emerging country specific evidence doubting the existence of a private school advantage i use pisa 2012 data for mathematics and two different methodologies to derive baseline and bias corrected estimates of the private dependent and independent school effect for 40 countries a robust private school advantage is found only in a handful of countries public schools generally perform as well as private subsidized schools and outperform independent schools accounting for both peer effects and selection is necessa
