the existence of non elite private schools we provide an explanation to the puzzle of the existence of paid for private schools that offer lower quality education than some tuition free public alternatives we consider a model of a city composed of two communities the urban area and the suburbs the suburban public school provides higher quality education at an implicit price the higher tax burden plus a housing rent premium if that price is high enough and the urban public school has a sufficiently low quality intermediate income households live in the urban area and use a private school intermediate quality private schools then exist to serve these households demand lower and higher income households use different quality public schools therefore perfect income stratification across public and private education does not characterize this equilibrium

joseph schumpeter lecture ideology i develop a model of ideologies as collectively sustained yet individually rational distortions in beliefs concerning the proper scope of governments versus markets in processing and interpreting signals of the efficacy of public and market provision of education health insurance pensions etc individuals optimally trade off the value of remaining hopeful about their future prospects or their children s versus the costs of misinformed decisions because these future outcomes also depend on whether other citizens respond to unpleasant facts with realism or denial endogenous social cognitions emerge thus an equilibrium in which people acknowledge the limitations of interventionism coexists with one in which they remain obstinately blind to them embracing a statist ideology and voting for an excessively large government conversely an equilibrium associated with appropriate public responses to market failures coexists with one dominated by a laissez faire ideology and blind faith in the invisible hand with public sector capital this interplay of beliefs and institutions leads to history dependent dynamics the model also explains why societies find it desirable to set up constitutional protections for dissenting views even when ex post everyone would prefer to ignore unwelcome news jel h11 d72 d83 p16 z1

tradeoffs and complementarities in the adoption of improved seeds fertilizer and natural resource management technologies in kenya there is widespread consensus that agricultural technology has an important role to play for poverty reduction and sustainable development there is no consensus however about the types of technologies that are best suited for smallholder farmers in africa while some consider natural resource management nrm technologies as most appropriate others propagate input intensification with a stronger role of the private sector in the public debate these two strategies are often perceived as incompatible environmental non governmental organizations in particular consider low external input strategies as the only sustainable form of agriculture a view that has considerable influence on policymakers and the international donor community most existing research studies on smallholder innovation focus on the adoption of individual technologies so that comparisons between different types of technologies in the same context are not easily possible we use representative data from maize producing households in kenya and a multivariate probit model to analyze the adoption of different types of technologies simultaneously results indicate that nrm technologies and strategies that build on external inputs are not incompatible interesting complementarities exist which are not yet sufficiently exploited because many organizations promote either one type of technology or the other but rarely a combination of both

valuing english primary schools this paper provides the first empirical evidence for the uk on the effect of primary school performance on property prices we find that on average a one percentage point increase in the neighbourhood proportion of children reaching the government specified target grade pushes up neighbourhood property prices by 0 67 at 2000 property prices we calculate the social valuation of a sustained 1 improvement in primary school performance to be up to 90 per child per year our instrumental variable and semi parametric approach avoids the problems of school quality endogeneity and omitted neighbourhood variables that occur in typical property value models

world poverty and the role of agricultural technology direct and indirect effects agricultural technology can help reduce poverty through direct and indirect effects direct effects are gains for the adopters while indirect effects are gains derived from adoption by others leading to lower food prices employment creation and growth linkage effects conceptualising and measuring these effects is highly complex yet is needed for each region if technology is to be used as an effective instrument for poverty reduction we propose a methodology for doing this in the context of computable general equilibrium modelling and apply it to archetype models for africa asia and latin america results show that the dominant effect of technology on poverty is through direct effects in africa indirect agricultural employment effects in asia and linkage effects through the rest of the economy in latin america in each case increasing the poverty reduction effect through the targeting of technology across crops and through complementary rural development programmes is also explored

tests of a rational theory of the size of government in many countries the political party holding power changes more frequently than the trend growth rates in government spending and taxes shifts of political power are often preceded by rhetoric about meeting needs or cutting taxes which post election performances rarely match yet changes in the size of government up and down occur on average the size of government measured by the share of taxes or spending to output has increased in many countries during the past century but changes in size occur at diffrent rates and at times the relative size of government declines

ideology and the growth of government abstract we analyze the impact of ideology on the size of government in a simple model the government sets redistribution and provision of public services according to the preferences of the median voter ideology is defined in terms of preferences for public services and the impact of ideology on the size of government is shown to increase with mean income this idea is tested using measures of ideology based on party manifestos we show that the interaction of ideology and mean income has a major role in explaining the increase and divergence in government size observed across oecd countries

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

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

does school tracking affect equality of opportunity new international evidence this paper investigates whether the interaction between family background and secondary school tracking affects human capital accumulation a widely shared view is that more tracking reinforces the role of parental privilege and thereby reduces equality of opportunities this may occur for several reasons including peer effects more talented students are gathered together teacher sorting better teachers prefer teaching better students differences in curricula academic oriented schools like the german gymnasium the french lycee the british grammar school or the italian liceo teach abilities that increase the probability of entering college and or differences in resource endowment compared to the current literature which focuses on early outcomes such as test scores at 13 and 15 years old we look at later outcomes including literacy dropout rates college enrolment employability and earnings while we do confirm the common view that school tracking reinforces the impact of family background when looking at educational attainment and labour market outcomes we do not confirm the same results when studying its impact on literacy and on the job training overall school tracking has an ambiguous effect in our sample of countries on the one hand and consistently with the previous literature tracking has a detrimental impact on educational attainment because it prevents some individuals from further progressing to the tertiary level of education the diversion effect on the other hand the curricula offered in vocational schools seem more effective in promoting further training and adult competences the specialization effect thereby reducing the impact of parental background on these two outcomes thus reducing the extent of student tracking either by raising the age of first selection or by reducing the number of tracks available may be appropriate for increasing intergenerational mobility in educational attainment but may increase social exclusion for people from disadvantaged backgrounds giorgio brunello and daniele checchi

the provision of public goods under alternative electoral incentives politicians who care about the spoils of office may underprovide a public good because its benefits cannot be targeted to voters as easily as pork barrel spending we compare a winner take all system where all the spoils go to the winner to a proportional system where the spoils of office are split among candidates proportionally to their share of the vote in a winner take all system the public good is provided less often than in a proportional system when the public good is particularly desirable we then consider the electoral college system and show that it is particularly subject to this inefficiency

the impact of domestic and global trade liberalisation on five southern african countries we compare the impact of alternative domestic and global trade liberalisation scenarios on five economies in southern africa the study applies a computable general equilibrium model that employs standardised 12 sector social accounting matrices for malawi mozambique tanzania zambia and zimbabwe the approach incorporates stylised features such as own household consumption and marketing margins that are of particular importance when a majority of agricultural producers are not sufficiently integrated into formal markets and thus rely on own production to meet their daily diets hence improved infrastructure implies lower marketing costs and better market integration which translates to increased production opportunities the comparison of the results across all five countries reveals that common policy measures have different impacts depending on the underlying economic structures

constitutional rules and fiscal policy outcomes we investigate the effect of electoral rules and forms of government on fiscal policy outcomes in a large sample of democracies we rely on different estimation methods to address prospective problems of statistical inference due to non random selection of these constitutional rules the findings are consistent with our theoretical priors presidential regimes induce smaller governments than parliamentary democracies while majoritarian elections lead to smaller governments and smaller welfare programs than proportional elections

the size and scope of government comparative politics with rational politicians we try to demonstrate how economists may engage in research on comparative politics relating the size and composition of government spending to the political system a downsian model of electoral competition and forward looking voting indicates that majoritarian as opposed to proportional elections increase competition between parties by focusing it into some key marginal districts this leads to less public goods less rents for politicians more redistribution and larger government a model of legislative bargaining and backward looking voting indicates that presidential as opposed to parliamentary regimes increase competition between both politicians and voters this leads to less public goods less rents for politicians less redistribution and smaller government we confront these predictions with cross country data from around 1990 controlling for economic and social determinants of government spending we nd strong and robust support for the prediction that the size of government is smaller under presidential regimes and weaker support for the prediction that majoritarian elections are associated with less public goods

wagner s hypothesis in time series and cross section perspectives evidence from real data for 115 countries internationally comparable data on income and government expenditure for 115 countries covering the period 1950 80 are used to assess the validity of wagner s hypothesis individual country time series data and several intercountry cross sections are studied besides a tremendous diversity in the position for various countries the results indicate that while there is support for the hypothesis in some time series data sets such support is lacking in most cross section estimates much of the support for the hypothesis reported in many earlier studies therefore was probably due to either use of limited samples or inadequate data comparability across the observations studied copyright 1987 by mit press

electoral systems and public spending we study the effects of electoral institutions on the size and composition of public expenditure in oecd and latin american countries we emphasize the distinction between purchases of goods and services which are easier to target geographically and transfers which are easier to target across social groups we present a theoretical model in which voters anticipating government policymaking under different electoral systems have an incentive to elect representatives more prone to transfer public good spending in proportional majoritarian systems the model also predicts higher total primary spending in proportional majoritarian systems when the share of transfer spending is high low after dee ning rigorous measures of proportionality to be used in the empirical investigation we e nd considerable support for our predictions

social mobility and redistributive politics just like economists voters have conflicting views about redistributive taxation because they estimate its incentive costs differently we model rational agents as trying to learn from their dynastic income mobility experience the relative importance of effort and predetermined factors in the generation of income inequality and therefore the magnitude of these incentive costs in the long run left wing dynasties believing less in individual effort and voting for more redistribution coexist with right wing dynasties this allows us to explain why individual mobility experience and not only current income matters for political attiitudes and how persistent differences in perceptions about social mobility can generate persistent differences in redistribution across countries

jockeying for position strategic high school choice under texas top ten percent plan abstract beginning in 1998 all students in the state of texas who graduated in the top 10 of their high school classes were guaranteed admission to any in state public higher education institution including the flagships while the goal of this policy is to improve college access for disadvantaged and minority students the use of a school specific standard to determine eligibility could have unintended consequences students may increase their chances of being in the top 10 by choosing a high school with lower achieving peers our analysis of students school transitions between 8th and 10th grade three years before and after the policy change reveals that this incentive influences enrollment choices in the anticipated direction among the subset of students with both motive and opportunity for strategic high school choice at least 5 enroll in a different high school to improve the chances of being in the top 10 these students tend to choose the neighborhood high school in lieu of transferring to more competitive schools and regardless of own race typically displace minority students from the top 10 pool relatively few students have both the motive and opportunity to behave strategically in the short run so systemic effects are inherently slight our finding of sizable take up in the face of costly strategizing however suggests that endogenous group membership may be important in the longer run and in other settings where individuals can select their peers and are then graded on a curve

the curious attraction of wagner s law wagner s law of increasing state activity has recently been subjected to intensive use of recondite econometric testing procedures an examination of the relevant articles reveals ignorance both of wagner s definition of state activity and of his insistence that he was not engaged in prediction consequently the omission of public enterprises contained in wagner s definition leads to a model misspecification and the object of testing his hypothesiss remains obscure

modeling the impact of agricultural growth and government policy on income distribution in india this article uses a limited general equilibrium model to investigate the growth and equity effects of a variety of economic and technical changes and selected agricultural policies in india it explores how changes in food prices rural wages and farm profits associated with the green revolution period affected income distribution between net buyers and sellers of food the model shows that income gains from the green revolution initially accrued to the wealthier rural groups but that after 1972 73 they were transferred to urban consumers and that by 1980 81 the per capita incomes of poor and wealthier rural groups alike were barely above their respective 1960 61 levels the model is also used in counterfactual analysis of the impact of changes in technological demographic investment taxation and income redistribution variables its findings indicate the importance of trade policies for the nature of the equity outcomes from agricultural growth and suggest that a reduction in population growth and an increase in nonagricultural employment and income are required to convert agricultural growth into reduced rural poverty

the role of agriculture in economic development visible and invisible surplus transfers the financial surplus of agriculture has been central to theories of the role of agriculture in economic development morrisson and thorbecke mt have used a constant price social accounting matrix sam framework to measure rigorously the financial surplus of agriculture and decompose the mechanisms of surplus extraction history and theory have however stressed the role of prices as an invisible transfer mechanism in addition to the visible transfers identified in the sam framework we extend the mt approach by defining and measuring the real surplus of agriculture and decomposing the mechanisms of surplus extraction between visible and invisible financial transfers using an archetype computable general equilibrium model for poor african nations we trace the generation transfer and use of an agricultural surplus created by a productivity gain in agriculture this shows that prices indeed play an overwhelmingly important role in transferring a surplus from agriculture to the benefit of the rest of

agricultural technology adoption and poverty reduction a propensity score matching analysis for rural bangladesh this study aims at shedding some light on the potential impact of agricultural technology adoption on poverty alleviation strategies it does so through an empirical investigation of the relationship between technological change of the green revolution type and wellbeing of smallholder farm households in two rural bangladeshi regions as technology adoption is not randomly assigned but there is self selection into treatment the paper tackles a methodological issue in assessing the causal effect of technology on farm household wellbeing through the non parametric p score matching analysis it pursues a targeted evaluation of whether adopting a modern seed technology causes resource poor farmers to improve their income and decrease the propensity to fall below the poverty line it finds a robust and positive effect of agricultural technology adoption on farm household wellbeing suggesting that there is a large scope for enhancing the role of agricultural technology in directly contributing to poverty alleviation 2006 elsevier ltd all rights reserved

the desegregating effect of school tracking this paper makes the following point detracking schools that is preventing them from allocating students to classes according to their ability may lead to an increase in income residential segregation it does so in a simple model where households care about the school peer group of their children if ability and income are positively correlated tracking implies that some high income households face the choice of either living in the areas where most of the other high income households live and having their child assigned to the low track or instead living in lower income neighbourhoods where their child would be in the high track under mild conditions tracking leads to an equilibrium with partial income desegregation where perfect income segregation would be the only stable outcome without tracking

comparative politics and public finance we propose a model with micropolitical foundations to contrast different political regimes compared to a parliamentary regime the institutions of a presidential congressional regime produce fewer incentives for legislative cohesion but more separation of powers these differences are reflected in the size and composition of government spending a parliamentary regime has redistribution toward a majority less underprovision of public goods and more rents to politicians a presidential congressional regime has redistribution toward powerful minorities more underprovision of public goods but less rents to politicians the size of government is smaller under a presidential regime this last prediction is consistent with cross country data

the concept of the agricultural surplus abstract the concept of the agricultural surplus has occupied a central place in the history of economic thought and has been used in a variety of different senses the major objective of this paper is to offer a rigorous definition of the agricultural surplus based on the social accounting matrix sam framework a sam for indonesia distinguishing between agriculture and non agriculture is used to estimate quantitatively the magnitude of the agricultural surplus and its various components finally the various meanings which have been assigned to this concept in the literature are reviewed and confronted with the definition which we derived

equity and efficiency in human capital investment the local connection a general model of community formation and human capital accumulation with social spillovers and decentralized school funding is used to analyse the causes of economic segregation and its consequences for equity and efficiency significant polarization arises from minor differences in endowments preferences or access to capital markets this makes income inequality more persistent across generations but the same need not be true for wealth equilibrium stratification tends to be excessive resulting in low aggregate surplus whether state equalization of school resources can remedy these problems hinges on how purchased social and family inputs interact in education and in mobility decisions

which school attributes matter the influence of school district performance and demographic composition on property values abstract increasing levels of segregation in american schools raises the question do home buyers pay for test scores or demographic composition this paper uses connecticut panel data spanning eleven years from 1994 to 2004 to ascertain the relationship between property values and school district attributes such as student test scores and the racial and ethnic composition of the student body town and census tract fixed effects are included to control for neighborhood unobservables the effect of changes in school district attributes is also examined over a decade long time frame in order to focus on the effect of long run changes which are more likely to be capitalized into prices the study finds strong evidence that increases in percent hispanic have a negative effect on housing prices in connecticut but mixed evidence concerning the impact of test scores on property values student test scores also appear to have increased in importance for explaining housing prices in recent years while the importance of percent hispanic has declined finally the study finds that estimates of property tax capitalization increase substantially when the analysis focuses on long run changes

the size of government in majoritarian and consensus democracies this article looks at the effect of democratic institutions on the size of government with the help of the ordinary least squares regression analysis of data from the organization for economic cooperation and development oecd countries from 1974 to 1995 the study provides considerable evidence that the variance in the type of democracy measured by the lijphart index of majoritarian consensus political institutions has a systematic effect on the variance in the size of government measured both by total government outlays as well as total government revenue as a percentage of gross domestic product the article further argues that such institutional effects on the size of government are strengthened by partisan politics more specifically the analysis demonstrates the presence of the multiplicative interaction effect of the mutually reinforcing nature between the institutional structure and partisan composition of government in their association with the size of government

constitutions politics and economics a review essay on persson and tabellini s the economic effects of constitutions in this essay i review the new book by torsten persson and guido tabellini the economic effects of constitutions which investigates the policy and economic consequences of different forms of government and electoral rules i also take advantage of this opportunity to discuss the advantages and disadvantages of a number of popular empirical strategies in the newly emerging field of comparative political economy

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

ideology and the size of us state government this paper theorizes that the impact of ideology on the size of us state governments increases with state income this idea is tested using state level ideology data derived from the voting behavior of state congressional representatives empirically the interaction of ideology and mean income is a key determinant of state government size at 1960s levels of income the impact of ideology is negligible at 1997 levels of income a one standard deviation move towards the left of the ideology spectrum increases state government size by about half a standard deviation estimated income elasticities differentiated by state and time are found to be increasing with ideology and diminishing with income as predicted by the theory

partisan politics and public finance changes in public spending in the industrialized democracies 1955 1989 this paper evaluates the role that partisan politics plays in altering public spending levels the analysis covers over three decades of data on the developments of the public sectors in 16 oecd countries the results of the analysis lend firm support to the partisan politics model of special note is the distinction between the electorate and the government ideological preferences and the dominant role that the former plays the results also suggest contrary to conventional wisdom that partisan political influences have not been eliminated with the tightening of linkages to the international economy

does government ideology matter in monetary policy a panel data analysis for oecd countries this paper examines whether government ideology has influenced monetary policy in oecd countries we use quarterly data in the 1980 1 2005 4 period and exclude emu countries our taylor rule specification focuses on the interactions of a new time variant index of central bank independence with government ideology the results show that leftist governments have somewhat lower short term nominal interest rates than rightwing governments when central bank independence is low in contrast short term nominal interest rates are higher under leftist governments when central bank independence is high the effect is more pronounced when exchange rates are flexible our findings are compatible with the view that leftist governments in an attempt to deflect blame of their traditional constituencies have pushed market oriented policies by delegating monetary policy to conservative central bankers

who s in charge of the central city the conflict between efficiency and equity in the design of a metropolitan area abstract a circular metropolitan area consists of a central city surrounded by a suburb households sort over the two jurisdictions based on public service levels and their costs of commuting to the metropolitan center using numerical simulations we show that 1 there typically exist two equilibria one in which the poor form the voting majority in the central city and the other in which the rich form the majority in the central city 2 there is an efficiency vs equity trade off as to which equilibrium is preferred and 3 if the central city contains only poor households equity favors expanding the central city to include rich households the third result arises not because of a fiscal subsidy from rich to poor households induced by a property tax but rather because of a change in house price capitalization

does the diversity of human capital increase gdp a comparison of education systems abstract this paper examines how different education systems affect gdp by influencing the diversity of human capital we construct an overlapping generation model in which agents are heterogeneous in income and innate ability and the final goods are produced with differentiated intermediate goods it is shown that under a realistic condition the diversity of human capital induced by income inequality always lowers the gdp of the next period while the diversity of human capital induced by heterogeneous ability can increase gdp if the produced intermediate goods are sufficiently substitutable and firms have a large span of control hence as public education equalizes education resources across households it mitigates the negative effect of income inequality on gdp while the effects of ability tracking crucially depend on the production structure of the economy

agricultural incentives in developing countries measuring the effect of sectoral and economywide policies the impact of sector specific direct and economywide indirect policies on agricultural incentives for 18 developing countries for the period 1975 84 are estimated the direct effect is measured by the proportional difference between the producer price and the border price adjusting for distribution storage transport and other marketing costs the indirect effect has two components 1 the impact of the unsustainable portion of the current account deficit and of industrial protection policies on the real exchange rate and thus on the price of agricultural commodities relative to nonagricultural nontradables and 2 the impact of industrial protection policies on the relative price of agricultural commodities to that of nonagricultural tradable goods the authors found that a in almost all cases the direct effect is equivalent to a tax on exportable goods and to a subsidy for importables b the indirect effect also taxes agriculture and dominates the direct effect and c the direct policies for both importables and exportables stabilize domestic producer prices

public provision of private goods government may provide a good that can if legally permitted be supplemented by private purchases policy is determined by majority rule under standard assumptions on preferences a majority voting equilibrium exists a regime of positive government provision with no restriction on private supplements is shown to be majority preferred to a regime of either only market provision or only government provision combined public and private expenditure on the good is higher under this dual provision regime than under either of the alternatives under some preference configurations the median income voter is pivotal under others a voter with income below the median is pivotal

school finance spatial income segregation and the nature of communities in a general equilibrium model that links school and housing markets a purely public school system regardless of the degree of centralization results in substantially more spatial income segregation than a purely private system however the combination of a public system with a private school market yields the least residential segregation as housing price distortions from the capitalization of the public system generate incentives for middle and high income private school attendees to live with lower income public school attendees the impact of vouchers and the sensitivity of results to alternative school production models is also investigated

school tracking and intergenerational income mobility evidence from the finnish comprehensive school reform abstract this paper estimates the effect of a major education reform on intergenerational income mobility the finnish comprehensive school reform of 1972 1977 replaced the old two track school system with a uniform nine year comprehensive school and shifted the selection of students to vocational and academic tracks from age 11 to age 16 we estimate the effect of this reform on the intergenerational income elasticity using a representative sample of males born between 1960 and 1966 the identification strategy relies on a differences in differences approach and exploits the fact that the reform was implemented gradually across the country during a six year period the results indicate that the reform reduced the intergenerational income elasticity by 23 from the pre reform elasticity of 0 30 to post reform elasticity of 0 23

peer group effects and educational attainment abstract given the aims of an educational system the relationship between educational inputs and educational outputs the educational production function a frequency distribution of students by ability and a fixed educational budget how should students and educational expenditures be allocated over classrooms the paper focuses on peer group effects which capture the influence of a student s classmates on his educational attainment and the determinants of whether streaming or mixing is preferable it should be noted that peer group effects arise in other contexts notably in the workplace thus the paper casts some light on the optimal composition of teams

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

agricultural technology productivity and poverty in madagascar summary this paper uses a unique spatially explicit dataset to study the link between agricultural performance and rural poverty in madagascar we show that controlling for geographical and physical characteristics communes that have higher rates of adoption of improved agricultural technologies and consequently higher crop yields enjoy lower food prices higher real wages for unskilled workers and better welfare indicators the empirical evidence strongly favors support for improved agricultural production as an important part of any strategy to reduce the high poverty and food insecurity rates currently prevalent in rural madagascar
