aid volatility policy and development summary we build on bulir and hamann s analysis of aid volatility bulir a hamann j 2003 aid volatility an empirical assessment imf staff papers 50 1 64 89 bulir a hamann j 2008 volatility of development aid from the frying pan into the fire washington dc imf paper submitted to this special section showing that the conclusions reached depend on the dataset used their argument that the poorest countries have the highest volatility appears not to be correct the impact of volatility on growth is negative overall but differs between positive and negative volatility the mix between responsive components of aid for example programme aid and proactive components for example technical assistance is important finally we conclude that measures which increase trust between donor and recipient and reductions in the degree of donor oligopoly reduce aid volatility without obviously reducing its effectiveness

measuring program impacts on earnings and employment do unemployment insurance wage reports from employers agree with surveys of individuals this article attempts to determine whether wage records reported by employers to state unemployment insurance ui agencies provide a valid alternative to more costly retrospective sample surveys o

aid and sectoral growth evidence from panel data this article examines empirically the proposition that aid to poor countries is detrimental for external competitiveness giving rise to dutch disease type effects at the aggregate level aid is f

does aid affect governance why is there little robust evidence that foreign aid significantly enhances the economic growth of poor countries the search for an explanation is becoming immensely important as industrial countries are being exhorted to increase their aid budgets in order to help developing countries achieve the millennium development goals perhaps one should not expect an impact on growth from the mere infusion of additional capital into a country but perhaps any beneficial effects are offset by adverse spillover effects and academic focus should shift to determining what these are and how to mitigate them in this regard figure is suggestive we plot the log of the manufacturing to gross domestic product gdp ratio in a country against the log of the ratio of aid received to gdp for that country for two separate time periods the late 990s and the early 980s conditional on a number of variables as the figure suggests the more aid a country has received the smaller its share of manufacturing the coefficient estimate suggests that a percentage point increase in the ratio of aid to gdp is associated with a reduced share of manufacturing in total gdp of about 0 2 to 0 3 percentage points

on the empirics of foreign aid and growth the present paper re examines the effectiveness of foreign aid theoretically and empirically using a standard olg model we show that aid inflows will in general affect long run productivity the size and direction of the impact may depend on policies deep structural characteristics and the size of the inflow the empirical analysis investigates these possibilities overall we find that aid has been effective in spurring growth but the magnitude of the effect depends on climate related circumstances finally we argue that the collier dollar allocation rule should be seriously reconsidered by donor agencies if aid effectiveness is related to climate the usefulness of foreign aid in promoting growth in developing countries has been an area of controversy ever since rosenstein rodan in 1943 advocated for aid to eastern and south eastern europe browsing through successive editions of a leading textbook in development economics provides a telling illustration of how the confidence in aid effectiveness dwindled over the years in the first edition of leading issues in economic development meier 1964 dedicated a full 18 page section to the issue of foreign aid he started out asking how much aid by the time of the sixth edition meier 1995 the treatment of foreign aid had been cut into half and the questions in focus were why official assistance and does aid work in the 2000 edition meier and rauch 2000 foreign aid is not even listed in the index

the benefits and costs of the section 8 existing housing program abstract the demand side section 8 existing housing program begun in 1975 is currently the second largest low income housing program in the united states with over one million units this paper presents estimates of the benefits and costs of the program and examines its allocative and distributive effects the effects of section 8 existing are compared with those under an alternative program of equal subsidy unrestricted cash grants among other things it is found that the average monthly subsidy of 100 is valued by recipients at 83 on average recipients are induced to consume 11 percent more housing and 6 percent less of other goods than they would with the cash grant recipient households near the eligibility income limits do not receive so large a benefit as to become better off than ineligible households the poorest and largest families receive the largest benefit other things equal however most poorer families are excluded while some richer families participate and equally situated families do not receive the same offer of assistance

social and spatial networks in labour markets social connections and referrals are ubiquitous in the labour market both on the job seeker side and on the employer side this article reviews recent developments in the study of referrals highlighting what we have learned regarding the use and impact of referrals on various labour market outcomes and pointing out the increasingly nuanced picture we are gaining on the effects of referrals it then discusses directions for future research emphasizing the importance of using newly available data and combinations of datasets and of making tighter connections with the burgeoning macro labour research that is based on a search and matching framework finally it evaluates the role of referrals from the point of view of policy makers discussing their social welfare implications and ways in which they could be explicitly incorporated into various labour market policies the importance of tighter collaboration between policy makers researchers employers and practitioners is stressed to conduct more rigorous experimentation and evaluation of potential referral based policies and programmes

an empirical model of labor supply in a life cycle setting this paper formulates and estimates a structural intertemporal model of labor supply using theoretical characterizations derived from an economic model of lifetime behavior a two step empirical analysis yields estimates of intertemporal and uncompensated substitution effects which provide the information needed to predict the response of hours of work to life cycle wage growth and shifts in the lifetime wage path

how does energy consumption affect china s urbanization new evidence from dynamic threshold panel models abstract energy consumption may play different roles at different stages of urbanization and economic growth given china s rapid economic development and urbanization process this study tries to explore the possible nonlinear relationship between energy consumption and urbanization in china against the background of promoting new type urbanization the level of china s urbanization is evaluated comprehensively using the entropy method a newly developed dynamic threshold panel model is employed to examine the nexus of energy consumption and comprehensive urbanization with full consideration of heterogeneous characteristics the panel data vector autoregression or pvar model is also used to estimate the direct effects of various energy consumption patterns on the urbanization the empirical results indicate that the nexus of energy consumption and urbanization is indeed nonlinear and that energy consumption is conducive to promote china s urbanization at the current stage of development however the positive effect decreases when there is an increase in energy consumption intensity and energy consumption scale whereas the effect increases with the promotion of energy consumption structure

bounds on elasticities with optimization frictions a synthesis of micro and macro evidence on labor supply how can price elasticities be identified when agents face optimization frictions such as adjustment costs or inattention i derive bounds on structural price elasticities that are a function of the observed effect of a price change on demand the size of the price change and the degree of frictions the degree of frictions is measured by the utility losses agents tolerate to deviate from the frictionless optimum the bounds imply that frictions affect intensive margin elasticities much more than extensive margin elasticities i apply these bounds to the literature on labor supply the utility costs of ignoring the tax changes used to identify intensive margin labor supply elasticities are typically less than 1 of earnings as a result small frictions can explain the differences between micro and macro elasticities extensive and intensive margin elasticities and other disparate findings pooling estimates from existing studies i estimate a hicksian labor supply elasticity of 0 33 on the intensive margin and 0 25 on the extensive margin after accounting for frictions

transfers in cash and in kind theory meets the data we review theoretical explanations for in kind transfers in light of the limited empirical evidence after reviewing the traditional paternalistic arguments we consider explanations based on imperfect information and self targeting we then discuss the large literature on in kind programs as a way of improving the efficiency of the tax system and a range of other possible explanations including the samaritan s dilemma pecuniary effects credit constraints asymmetric information amongst agents and political economy considerations our reading of the evidence suggests that paternalism and interdependent preferences are leading overall explanations for the existence of in kind transfer programs but that some of the other arguments may apply to specific cases political economy considerations must also be part of the story

measuring economic efficiency using inverse optimum weights abstract this paper provides a method to measure the traditional kaldor hicks notion of economic efficiency when taxes affect behavior in contrast to traditional unweighted surplus measuring efficiency requires weighting individual benefits or surplus by the marginal cost to the government of providing a 1 transfer at each income level these weights correspond to the solution to the inverse optimum program in the optimal tax literature they are the social planning weights that would rationalize the status quo tax schedule as optimal i estimate the weights using the universe of us income tax returns from 2012 the results suggest that measuring economic efficiency requires weighting surplus accruing to the poor roughly 1 5 2 times more than surplus accruing to the rich this is because 1 of surplus to the poor can be turned into roughly 1 5 2 of surplus to the rich by reducing the progressivity of the tax schedule following kaldor and hicks original applications i compare income distributions over time in the us and across countries the results suggest us economic growth is 15 20 lower due to increased inequality than is suggested by changes in gdp because of its higher inequality the u s is unable to replicate the income distribution of countries like austria and the netherlands despite having higher national income per capita

family labor supply and the timing of cash transfers evidence from the earned income tax credit abstract this paper exploits the unique disbursement timing and benefit rules of the earned income tax credit eitc to provide new evidence on how families adjust their labor supply in response to receiving anticipated cash transfers i find that income seasonality caused by eitc receipt leads to changes in the intra year labor supply patterns of married women on average receiving a 1 000 payment significantly reduces the proportion of married women who work by 1 3 percentage points in the month when the eitc is received additionally this labor supply response is mainly driven by those who are secondary earners or liquidity constrained

consequences of aid volatility for macroeconomic management and aid effectiveness we conclude that individual aid sector volatility matters as well as total aid volatility easily the most important contributor to total volatility is debt aid the most volatile aid sectors per se include debt industry and humanitarian and the least include education and health in several sectors volatility appears to have peaked around 2006 within individual countries sector volatility is often corrected for in the following period there are also sometimes knock on effects on other sectors finally we examine the impact of sector aid and aid volatility on school completion rates death rates internet usage and mobile phone subscriptions

moving to opportunity in boston early results of a randomized mobility experiment this paper examines the short run impacts of a change in residential neighborhood on the well being of low income families using evidence from a program in which eligibility for a housing voucher was determined by random lottery we examine the experiences of households at the boston site of moving to opportunity mto a demonstration program in five cities families in high poverty public housing projects applied to mto and were assigned by lottery to one of three groups experimental offered mobility counseling and a section 8 subsidy valid only in a census tract with a poverty rate of less than 10 percent section 8 comparison offered a geographically unrestricted section 8 subsidy or control offered no new assistance but continued to be eligible for public housing our quantitative analyses of program impacts uses data on 540 families from a baseline survey at program enrollment a follow up survey administered l to 3 5 years after random assignment and state administrative data on earnings and welfare receipt 48 percent of the experimental group and 62 percent of the section 8 comparison group moved through the mto program one to three years after program entry families in both treatment groups were more likely to be residing in neighborhoods with low poverty rates and high education levels than were families in the control group however while members of the experimental group were much more likely to be residing in suburban communities than were those in the section 8 group the lower program take up rate among the experimental group resulted in more families remaining in the most distressed communities households in both treatment groups experienced improvements in multiple measures of well being relative to the control group including increased safety improved health among household heads and fewer behavior problems among boys experimental group children were also less likely to be a victim of a personal crime to be injured or to experience an asthma attack there are no significant impacts of either mto treatment on the employment earnings or welfare receipt of household heads in the first three years after random assignment

does job corps work impact findings from the national job corps study this paper presents findings from an experimental evaluation of job corps the nation s largest training program for disadvantaged youths the study uses survey data collected over four years and tax data over nine years on a nationwide sample of 15 400 treatments and controls the job corps model has promise program participation increases educational attainment reduces criminal activity and increases earnings for several postprogram years based on tax data however the earnings gains were not sustained except for the oldest participants nonetheless job corps is the only federal training program that has been shown to increase earnings for this population

impacts of urbanization on renewable energy consumption in china abstract in this paper we used the logarithmic mean divisia index method to investigate the impact of urbanization on renewable energy consumption growth recg the growth in renewable energy consumption is attributed to the urbanization effect energy mix effect energy intensity effect economic effect and population effect recg can be roughly divided into the slow growth stage the fluctuant growth stage and the accelerated growth stage the results showed that the energy mix effect economic effect and population effect positively affected recg however a significantly negative relationship was found between energy intensity and recg furthermore the contribution of urbanization differed in recg stages and urbanization contributed more to the total energy consumption growth than to recg this study would thus provide policymakers with insights about the link between urbanization and renewable energy consumption

housing demand and neighborhood choice with housing vouchers abstract this paper presents a new model of household choice of neighborhood and housing consumption and uses it to predict the effects of alternative housing voucher policies on the choices of voucher recipients and their levels of wellbeing the model is estimated using household level data from housing voucher recipients in pittsburgh aggregate data on unsubsidized households and a large dataset of neighborhood characteristics including crime rates school quality racial composition and housing prices using the estimated model this study predicts effects of a variety of interesting reforms of the housing voucher program namely a more generous voucher subsidy subsidy amounts that vary with census tract housing prices instead of metropolitan area prices subsidies that are proportional to the market rent of the specific units and a requirement that voucher recipients live in a census tract where the poverty rate is less than 30

the effects of housing and neighborhood conditions on child mortality in this paper we estimate the causal effects on child mortality from moving into less distressed neighborhood environments we match mortality data covering the period from 1997 to 2009 with information on every child in public housing that applied for a housing voucher in chicago in 1997 n 11 680 families were randomly assigned to the voucher wait list and only some families were offered vouchers the odds ratio for the effects of being offered a housing voucher on overall mortality rates is equal to 1 13 for all children 95 ci 0 73 1 70 1 34 for boys 95 ci 0 85 2 05 and 0 21 for girls 95 ci 0 01 1 04

supply push or demand pull strategic recommendations for the responsible development of biofuel in china this study investigates china s biofuel industry the third largest in the world by combining a strength weakness opportunity and threats swot analysis with a method known as fuzzy analytic hierarchy process fahp more specifically the study employs swot analysis to identify the influential factors affecting the development of the biofuel industry in china it then prioritizes their importance using the fahp method the study finds that high production costs competition with other renewable energy resources inconsistent policy and legislation support and poor technical standards are impeding the growth of the biofuel industry of china the study concludes by proposing strategic recommendations for how the industry can be made both leaner more efficient and effective and greener more socially and environmentally sustainable some of these options focuses on improving technical perform adhering to a supply push mentality others focus on improving affordability and consumer awareness adhering to a demand pull mentality

do low income housing subsidies increase the occupied housing stock abstract a necessary condition for justifying a policy such as subsidized low income housing either via tenant based rental assistance or construction of public or private projects is that it has a real effect on market outcomes in this paper we examine one aspect of the real effect of subsidized housing does it increase the housing stock if subsidized housing raises the quantity of occupied housing per capita either more people are finding housing or they are being housed less densely on the other hand if subsidized housing merely crowds out equivalent quality low income housing that otherwise would have been provided by the private sector the housing policy may have little real effect on housing consumption using both census place and msa level data from the decennial census and from the department of housing and urban development we ask whether housing markets with more subsidized housing also have more total housing after accounting for housing demand we find that government financed units raise the total number of units in a market although on average one government subsidized unit adds only one third to one half of a unit to the total housing stock there is less crowd out in more populous markets and more crowd out in places where there is less excess demand for subsidized housing as measured by the number of government financed units per eligible person tenant based housing programs such as section 8 certificates and vouchers seem to be more effective than project based programs at targeting subsidized housing units to people who otherwise would not have their own

estimating neighborhood choice models lessons from a housing assistance experiment we use data from a housing assistance experiment to estimate a model of neighborhood choice the experimental variation effectively randomizes the rents which households face and helps identify a key structural parameter access to two randomly selected treatment groups and a control group allows for out of sample validation of the model we simulate the effects of changing the subsidy use constraints implemented in the actual experiment we find that restricting subsidies to even lower poverty neighborhoods would substantially reduce take up and actually increase average exposure to poverty furthermore adding restrictions based on neighborhood racial composition would not change average exposure to either race or poverty jel i32 i38 r23 r38

a comparison of the labor supply findings from the four negative income tax experiments between 1968 and 1982 the united states federal government sponsored four negative income tax experiments this paper provides a set of consensus estimates of the labor supply responses to these experiments it is found that despite the wide range of treatments and evaluation methodologies the results are remarkably consistent on average husbands reduced labor supply by about the equivalent of two weeks of full time employment wives and single female heads reduced labor supply by about the equivalent of three weeks of full time employment youth reduced labor supply by about the equivalent of four weeks of full time employment estimated income and substitution effects are quite similar to those obtained from nonexperimental studies

fiscal composition and aid effectiveness a political economy model summary in the long run tax effort we argue determines the effectiveness of aid and this relationship operates simultaneously with the negative link in the opposite direction observed by brautigam and knack 2004 and others tax effort and the ability of the state to diversify its taxation structure we find are significantly linked to growth and poverty indicators the key message for policy is that a broadening of the tax structure in low income countries is crucial in order to enable those countries to escape from the weak state low tax trap and to make aid effective

safety net the use of vouchers when a place based rental subsidy ends the us government moved to a private ownership model for providing affordable housing in the 1960s which resulted in millions of housing units being developed and governed by affordability restric

long term earnings and employment effects of housing voucher receipt abstract using a propensity score matching approach coupled with difference in differences regression analysis we estimate the effect of housing voucher receipt on the employment and earnings of a large longitudinal sample of low income families for 6 years following voucher receipt our results indicate that voucher receipt has little effect on employment but a negative effect on earnings the negative earnings effect is largest in the years immediately following initial receipt and fades out over time in addition we find that the pattern of recipient earnings responses to voucher receipt differs substantially across demographic subgroups several robustness tests are run to support the reliability of our findings we discuss the implications of our findings for research and policy

the effects of housing assistance on labor supply evidence from a voucher lottery this study estimates the effects of means tested housing programs on labor supply using data from a randomized housing voucher wait list lottery in chicago economic theory is ambiguous about the expected sign of any labor supply response we find that among working age able bodied adults housing voucher use reduces labor force participation by around 4 percentage points 6 percent and quarterly earnings by 329 10 percent and increases temporary assistance for needy families program participation by around 2 percentage points 15 percent we find no evidence that the housing specific mechanisms hypothesized to promote work such as neighborhood quality or residential stability are important empirically jel i38 j22 r23 r38

housing wealth and labor supply evidence from a regression discontinuity design abstract this paper uses the discontinuity in house size generated by chinese housing policies to identify the effect of housing wealth on labor supply the analysis finds a substantial deterrent effect of housing wealth on labor supply much of the housing wealth effect comes from the labor participation decision with the effect on employed workers being ambiguous females young generation and households with high repayment capacity are more responsive to gains in housing wealth

u turns and full circles two decades of agricultural reform in malawi 1981 2000 abstract this paper traces the evolution of malawi s agricultural policy over the past two decades during this period the world bank has played a key role in shaping policy reform through its adjustment loans three distinct reform phases can be identified 1981 87 when policy was dominated by the dogmatism of the world bank s pricist and state minimalist policies 1988 94 when a more flexible position was taken by both the bank and the malawi government both of whom acknowledged the structuralist critique of earlier policies and 1994 to the present when the reform process in agriculture became more politicized and a schism developed between the bank and the government this latter period is used to illustrate some of the unresolved policy issues pertaining to similar low income agrarian economies

the plight of the biomass power generation industry in china a supply chain risk perspective abstract for the past several years the biomass power generation industry in china has witnessed notably rapid development however many biomass power generation manufacturers in china are currently making small profits or suffering losses and the entire biomass supply chain does not function well which not only poses a challenge for the stable operation of enterprises but also may impact the smooth development of the biomass power industry from the perspective of supply chain risk this paper explores the reasons for the current plight and the future obstacles that the chinese biomass power generation industry may face identifying such risks as market risk production risk technology risk economic risk and management risk in the upstream midstream and downstream of the biomass supply chain and ordering the degrees of risk controllability by the government and enterprises it is determined that joint effort by both the chinese government and the biomass power generation enterprises is an ideal choice for risk control coming out of the plight however at present more problems should go to the government for solutions than to the enterprises to guide the healthy development of the industry the chinese government should play a more prominent role in promulgating supporting policies in each stage of the supply chain and strengthening the supervision and control of biomass projects last specific measures taken by the chinese government and the enterprises are proposed

aid volatility and donor recipient characteristics in difficult partnership countries one factor limiting aid effectiveness is its volatility we examine aid volatility in 66 countries over 1975 2004 paying particular attention to the characteristics of difficult partnership countries and making a distinction between sector aid and total aid we explore whether weak recipient institutions and policies are associated with greater volatility allowing for differences in donor characteristics institutional quality and macroeconomic stability affect the stability of all kinds of aid as does reliance on a small number of donors however the relative importance of these effects varies across different aid types

can the world cut poverty in half how policy reform and effective aid can meet international development goals abstract poverty in the developing world will decline by about one half by 2015 if the trends of the 1990s persist most of this poverty reduction will occur in asia however while poverty will decline only slightly in africa effective aid could make a contribution to greater poverty reduction in lagging regions even more potent would be significant policy reform in these countries we develop a model of efficient aid in which flows respond to policy improvements that create a better environment for poverty reduction and effective aid we investigate scenarios of policy reform and efficient aid that point the way to how the world can cut poverty in half in every major region

the macroeconomic impact of aid volatility we analyse the impact of aid volatility on gdp gnp shares of expenditure given the level of aid positive and negative volatility reduce investment and government expenditure shares but the former reduces import share and the latter increases consumers expenditure share

aid poverty reduction and the new conditionality the paper examines the effect of aid on poverty rather than on economic growth we devise a pro poor public expenditure index and present evidence that together with inequality and corruption this is a key determinant of the aid s poverty leverage after presenting empirical evidence which suggests a positive leverage of aid donors on pro poor expenditure we argue for the development of conditionality in a new form which gives greater flexibility to donors in punishing slippage on previous commitments and keys aid disbursements to performance in respect of policy variables which governments can influence in a pro poor direction

aid policies and growth the authors of this paper use a new database on foreign aid to examine the relationships among foreign aid economic policies and growth of per capita gdp in panel growth regressions for 56 developing countries and 6 four year periods 1970 93 they find that the policies that have a great effect on growth are those related to fiscal surplus inflation and trade openness they construct an index for those three policies and have that index interact with foreign aid they have instruments for both aid and aid interacting with policies they find that aid has a positive impact on growth in developing countries with good fiscal monetary and trade policies in the presence of poor policies aid has no positive effect on growth this result is robust in a variety of specifications which include or exclude middle income countries include or exclude outliers and treat policies as exogenous or endogenous they examine the determinants of policy and find no evidence that aid has systematically affected policies either for good or for ill they estimate an aid allocation equation and show that any tendency for aid to reward good policies has been overwhelmed by donors pursuit of their own strategic interests in a counterfactual they reallocate aid reduce the role of donor interests and increasing the importance of policy such a reallocation would have a large positive effect on developing countries growth rates

in kind transfers cash grants and labor supply abstract in kind and cash transfer programs are compared in their impacts on labor supply it is demonstrated that labor supply is higher under an in kind transfer program if in kind transfers and leisure are hicks substitutes leisure is normal and in kind transfers are over provided it is further shown that under these conditions a one dollar increase in in kind coupled with a one dollar cut in cash transfers increases tax revenues finally the paper proves that weak separability of preferences between leisure and other goods in addition to normality of leisure and normality and over provision of in kind transfers is also sufficient to ensure a higher level of labor supply under in kind transfers

moved to opportunity the long run effects of public housing demolition on children this paper provides new evidence on the effects of moving out of disadvantaged neighborhoods on the long run outcomes of children i study public housing demolitions in chicago which forced low income households to relocate to less disadvantaged neighborhoods using housing vouchers specifically i compare young adult outcomes of displaced children to their peers who lived in nearby public housing that was not demolished displaced children are more likely to be employed and earn more in young adulthood i also find that displaced children have fewer violent crime arrests children displaced at young ages have lower high school dropout rates

aid nontraded goods and the transfer paradox in small countries this paper constructs a model of the transfer paradox for a small open economy with nontraded goods it demonstrates that increased production of nontraded goods can change their domestic price so as to offset the otherwise beneficial effect of aid and under certain conditions to create a transfer paradox even in a small country the model is estimated with time series data for 44 aid dependent countries for the period 1970 90 the results support the model and show that the nontraded goods expansion effect is more likely to cause immiserization than harry g johnson s 1967 tariff distorting export displacement effect

there is no free house abstract this paper estimates the effect of a housing relocation program on the labor supply and living conditions of low income households across major cities in south africa using panel microdata collected between 2008 and 2014 it exploits the arbitrary eligibility rules of the policy with a fuzzy regression discontinuity design to obtain reduced form estimates there are three main findings first in the short term of 2 to 4 years following relocation the labor supply of recipient households decreases driven mostly by a reduction of female hours second the large increase in distance km to economic opportunities seems to be an important factor behind the decline directly or indirectly through family shifts in earning strategies finally evidence is limited regarding improvements in housing and neighborhood quality overall there is no clear indication that the net welfare effect of relocation is positive

in kind transfers and work incentives recent developments in rationing theory are used to examine the differences between the effects of in kind and cash transfers on labor supply it is not possible to tell a priori which type of transfer will cause the greater reduction in hours of work the answer depends on the extent to which in kind transfers distort consumption choices and on the relationship between the transferred commodities and leisure hicks allen complements can cause greater reductions in labor supply than equally generous cash transfers while strong hicks allen substitutes can induce increases in market work

targeting aid to the needy and deserving nothing but promises by reallocating aid to where it is needed most and where a productive use is most likely donors could help alleviate poverty in developing countries the rhetoric of donors suggests that this insight has increasingly shaped the allocation of aid we assess the poverty and policy orientation of bilateral and multilateral aid in different ways in addition to presenting stylised facts based on bivariate correlations we apply a tobit model that captures both altruistic and selfish donor motives we find little evidence supporting the view that the targeting of aid has improved significantly most donors provide higher aid to relatively poor countries but so far the fight against poverty has not resulted in a stronger focus on needy recipients with favourable local conditions the estimation results reveal that the policy orientation of aid critically depends on how local conditions are measured in general however donors appear to be less policy oriented than poverty oriented the response of donors to changing institutional and policy conditions in recipient countries turns out to be fairly weak we reject the proposition that multilateral aid is clearly superior to bilateral aid in terms of rewarding poor countries with better policies and institutions

redesigning the aid contract donors use of performance indicators in uganda abstract the perceived failure of traditional ex ante conditionality has led to proposals for using performance indicators as a basis for aid allocations ex post conditionality in this article we assess the role of performance indicators and their impact on the aid contract between donors and the government of uganda in uganda the use of performance indicators has radically changed donor recipient relations by improving both program monitoring and donor coordination it has however not yet fundamentally changed the incentive structure in the aid contract to improve the incentive structure we propose a distinction between indicators used for monitoring and those designed to guide aid allocations

a unified welfare analysis of government policies we conduct a comparative welfare analysis of 133 historical policy changes over the past half century in the united states focusing on policies in social insurance education and job training taxes and cash transfers and in kind transfers for each policy we use existing causal estimates to calculate both the benefit that each policy provides its recipients measured as their willingness to pay and the policy s net cost inclusive of long term impacts on the government s budget we divide the willingness to pay by the net cost to the government to form each policy s marginal value of public funds or its mvpf comparing mvpfs across policies provides a unified method of assessing their impact on social welfare our results suggest that direct investments in low income children s health and education have historically had the highest mvpfs on average exceeding 5 many such policies have paid for themselves as governments recouped the cost of their initial expenditures through additional taxes collected and reduced transfers we find large mvpfs for education and health policies amongst children of all ages rather than observing diminishing marginal returns throughout childhood we find smaller mvpfs for policies targeting adults generally between 0 5 and 2 expenditures on adults have exceeded this mvpf range in particular if they induced large spillovers on children we relate our estimates to existing theories of optimal government policy and we discuss how the mvpf provides lessons for the design of future research

how should structural adjustment programs be designed abstract more than seven years have elapsed since the onset of the generalized debt crisis of 1982 yet the affected countries have still not managed to stabilize their economies these countries must now attempt structural adjustment in the midst of pervasive macroeconomic and political instability structural adjustment packages should be designed with this reality in mind this paper argues that structural adjustment programs should strive for sustainability rather than the economic liberalization that they presently stress illiberal policies which do not damage overall macro stability are preferable to liberal policies which are inherently unsustainable or engender macro instability liberalization programs that are not sustainable are likely to bring few benefits but have high costs in terms of private investment the paper discusses some of the chief implications of this opinion for the design of adjustment programs

evaluating public programs with close substitutes the case of head start this paper empirically evaluates the cost effectiveness of head start the largest early childhood education program in the united states using data from the randomized head start impact study hsis we show that head start draws a substantial share of its participants from competing preschool programs that receive public funds this both attenuates measured experimental impacts on test scores and reduces the program s net social costs a cost benefit analysis demonstrates that accounting for the public savings associated with reduced enrollment in other subsidized preschools can reverse negative assessments of the program s social rate of return estimates from a semi parametric selection model indicate that head start is about as effective at raising test scores as competing preschools and that its impacts are greater on children from families unlikely to participate in the program efforts to expand head start to new populations are therefore likely to boost the program s social rate of return provided that the proposed technology for increasing enrollment is not too costly

landlords avoid tenants who pay with vouchers this paper uses a correspondence experiment with fictional housing applicants to test how landlords respond to tenants paying with a subsidized voucher landlords respond positively to those wishing to pay by voucher only half as often as to those indicating no such desire within the set of apartments eligible for voucher rent limits the voucher penalty increases with monthly rent landlord behavior places quantitatively important restrictions on the quantity and type of apartments available to voucher recipients

the impact of housing assistance on child outcomes evidence from a randomized housing lottery one long standing motivation for low income housing programs is the possibility that housing affordability and housing conditions generate externalities including on children s behavior and long term life outcomes we take advantage of a randomized housing voucher lottery in chicago in 1997 to examine the longterm impact of housing assistance on a wide variety of child outcomes including schooling health and criminal involvement in contrast to most prior work focusing on families in public housing we focus on families living in unsubsidized private housing at baseline for whom voucher receipt generates large changes in both housing and nonhousing consumption we find that the receipt of housing assistance has little if any impact on neighborhood or school quality or on a wide

possibilities and challenges of china s forestry biomass resource utilization abstract forestry biomass resource has many advantages which makes it a significant new energy to substitute fossil energy as an important role of biomass resources for the utilization of china s forestry biomass resources this paper analyzed the possibilities of its development from the aspect of policy resource endowment market and technology and discussed its development challenges from the aspect of policy economy society technology and resource endowment forestry biomass resources are very abundant in china it has made a significant breakthrough in forest biomass resource utilization with great prospects although there are still some difficulties and challenges in the policy resource endowment and other aspects these challenges are not insurmountable therefore forestry biomass resources should develop in a way with chinese characteristics considering the national condition

mechanism experiments and policy evaluations randomized controlled trials are increasingly used to evaluate policies how can we make these experiments as useful as possible for policy purposes we argue greater use should be made of experiments that identify the behavioral mechanisms that are central to clearly specified policy questions what we call mechanism experiments these types of experiments can be of great policy value even if the intervention that is tested or its setting does not correspond exactly to any realistic policy option

darlings and orphans interactions across donors in international aid we examine how bilateral aid flows of an individual donor to a recipient depend on aid flows from all other bilateral and multilateral donors to that recipient we thereby assess to what extent issues including donor coordination free riding selectivity specialization and common donor interests drive bilateral aid allocations we find that others bilateral flows lead to a significant increase in aid flows from a particular donor but primarily within a given year the effects are particularly pronounced for large donors and so called darling recipients overall the results suggest that herding is a dominant feature of aid inter relationships this article is protected by copyright all rights reserved

on aid growth and good policies this study provides a critical analysis of the growth regressions in burnside and dollar 2000 first we analyse the relationship between aid and government expenditure in a modified neo classical growth model one of the main results of the analysis is that while good policies spur growths they may at the same time reduce the effectiveness of foreign aid second we show that the econometric results in burnside and dollar emphasising the crucial role of interaction between aid and good policies in the growth process are fragile as they are extremely data dependent finally we demonstrate that the burnside and dollar data lend support to the idea that the association between aid and growth can be approximated by decreasing returns to aid this finding conforms well to regression results in other recent studies

aid effectiveness opening the black box this paper examines the causality chain linking aid flows to development outcomes it argues that many of the questions policymakers and economists would like data to answer simply cannot be answered due to the complexity and noise along links in the chain and the problem of attribution it then examines what is known about aid effectiveness along different links in the causality chain finally it turns to recent trends in the way aid is delivered and the new model that appears to be emerging

the anarchy of numbers aid development and cross country empirics the recent literature contains many stories of how foreign aid affects economic growth aid raises growth in countries with good policies or with difficult economic environments or outside the tropics or on average but with diminishing returns the diversity of the results suggests that many are fragile seven important aid growth papers are tested for robustness using 14 minimally arbitrary tests deriving mainly from differences among the studies themselves this approach investigates the importance of potentially arbitrary specification choices while minimizing the arbitrariness in testing choices all of the results appear fragile especially to sample expansion

housing vouchers income shocks and crime evidence from a lottery abstract employing exogenous variation in randomized wait list positions assigned using a lottery we identify the causal effects of section 8 housing vouchers on arrests of adult household heads based on administrative records from houston we find that voucher receipt has no effect on the likelihood of arrest even among the groups with the highest propensities for crime the vouchers have no impact income effects for these adults are particularly large relative to neighborhood effects leading us to believe that this large income shock does little to alleviate financial pressures that could lead to crime

labour supply effects of winning a lottery our article investigates how winning a substantial lottery prize affects labour supply analysing data from dutch state lottery winners we find that winning a lottery prize reduces labour earnings in the year of the winning as well as in the years after the winning this suggests that winning a lottery prize makes one work fewer hours the effects are small but statistically significant we do not find a significant effect of lottery prizes on the probability of being employed

aid instability as a measure of uncertainty and the positive impact of aid on growth this article contributes to the literature on aid and economic growth we posit that uncertainty measured as the instability of aid receipts will influence the relationship between aid and investment how recipient governments respond to aid and will capture the fact that some countries are especially vulnerable to shocks when we account for uncertainty which is negative and significant we find that aid has a significant positive effect on growth largely due to its effect on the volume of investment the finding that uncertainty of aid receipts reduces the effectiveness of aid is robust when the regression is estimated for the sub sample of african countries these findings hold although the effectiveness of aid appears weaker than for the full sample

does emergency financial assistance reduce crime abstract does emergency financial assistance reduce criminal behavior among those experiencing negative shocks to address this question we exploit quasi random variation in the allocation of temporary financial assistance to eligible individuals and families that have experienced an economic shock chicago s homelessness prevention call center hpcc connects such families and individuals with assistance but the availability of funding varies unpredictably consequently we can determine the impact of temporary assistance on crime by comparing outcomes for those who call when funds are available to those who call when no funds are available linking this call center information to arrest records from the chicago police department we find some evidence that total arrests fall between 1 and 2 years after the call for violent crime police arrest those for whom funds were available 51 less often than those who were eligible but for whom no funds were available single individuals drive this decrease the decline in crime appears to be related in part to greater housing stability being referred to assistance significantly decreases arrests for homelessness related outdoor crimes such as trespassing however we also find that financial assistance leads to an increase in property crime arrests this increase is evident for family heads but not single individuals the increase is mostly due to shoplifting and the timing of this increase suggests that financial assistance enables some families to take on financial obligations that they are subsequently unable to meet overall the change in the mix of crime induced by financial assistance generates considerable social benefits due to the greater social cost of violence

cross country evidence on the link between volatility and growth this paper presents empirical evidence against the standard dichotomy in macroeconomics that separates growth from the volatility of economic fluctuations in a sample of ninety two countries as well as a sample of oecd countries the authors find that countries with higher volatility have lower growth the addition of standard control variables strengthens the negative relationship the authors also find that government spending induced volatility is negatively associated with growth even after controlling for both time and country fixed effects copyright 1995 by american economic association

aid and growth what does the cross country evidence really show abstract we examine the effects of aid on growth in cross sectional and panel data after correcting for the possible bias that poorer or stronger growth may draw aid contributions to recipient co

aid and growth regressions this paper examines the relationship between foreign aid and growth in real gdp per capita as it emerges from simple augmentations of popular cross country growth specifications it is shown that aid in all likelihood increases the growth rate and this result is not conditional on good policy there are however decreasing returns to aid and the estimated effectiveness of aid is highly sensitive to the choice of estimator and the set of control variables when investment and human capital are controlled for no positive effect of aid is found yet aid continues to impact on growth via investment we conclude by stressing the need for more theoretical work before this kind of cross country regressions are used for policy purposes

do means tested transfers reduce labor supply abstract it is frequently argued that recipients of means tested government transfers work less than they would in the absence of the transfer this note shows that this conclusion may not be accurate for many participants in a major housing program

aid volatility and poverty traps abstract this paper studies the impact of aid volatility in a two period model where production may occur with either a traditional or a modern technology public spending is productive and time to build requires expenditure in both periods for the modern technology to be used the possibility of a poverty trap induced by high aid volatility is first examined in a benchmark case where taxation is absent the analysis is then extended to account for self insurance taking the form of a first period contingency fund financed through taxation an increase in aid volatility is shown to raise the optimal contingency fund but if future aid also depends on the size of the contingency fund as a result of a moral hazard effect on donors behavior the optimal policy may entail no self insurance

aid and the supply side public investment export performance and dutch disease in low income countries contemporary policy debates on the macroeconomics of aid often concentrate on short run dutch disease effects ignoring the possible supply side impact of aid financed public expenditure in the simple model of aid and public expenditure presented here public infrastructure generates an inter temporal productivity spillover which may exhibit a sector specific bias the model also provides for a learning by doing externality through which total factor productivity in the tradable sector is an increasing function of past export volumes an extended computable version of this model is used to simulate the effect of a step increase in net aid flows the simulations show that beyond the short run when conventional demand side dutch disease effects are present the relationship between enhanced aid flows and real exchange rates output growth and welfare is less straightforward than simple models of aid suggest public infrastructure investment that generates a productivity bias in favor of non tradable production delivers the largest aggregate return to aid but at the cost of deterioration in the income distribution income gains accrue predominantly to skilled and unskilled urban households leaving the rural poor relatively worse off under plausible parameterizations of the model the rural poor may also be worse off in absolute terms
