a framework for evaluating the impact of pricing policies for cocoa and coffee in cote d ivoire this article presents an approach to evaluating pricing policies for perennial crops a flexible computational model is developed which incorporates important features of perennial crop production that are not captured by other usually static frameworks this framework produces sensible and plausible scenarios for pricing cocoa and coffee in cote d ivoire as well as descriptions of revenue tradeoffs key issues arise from considering major changes in the rules used to set domestic producer prices an unambiguously best policy is not determined but several policies improve substantially on the present situation most of these alternatives indicate the desirability of lowering the tax on coffee relative to cocoa

tax collection with agency costs private contracting or government bureaucrats historically governments contracted with private agents known as tax farmers to collect taxes this paper develops a theoretical framework for determining when a welfare maximizing government should choose tax farmers over bureaucratic tax collectors while bureaucratic collectors have an incentive to shirk and raise collection costs above least costs profit maximizing private collectors tend to reduce tax evasion below the optimal level generally the choice of collection methods depends on a comparison of the welfare loss associated with monitoring in the bureaucratic setting and the welfare loss associated with overdetection of evasion in the private setting copyright 1992 by the london school of economics and political science

household survey data and pricing policies in developing countries in recent years household survey data from developing countries have increasingly become available and have been increasingly used to cast light on important questions of policy the reform of prices whether agricultural prices consumer taxes subsidies or tariffs has consequences for individual welfare and for government revenues and these can be investigated empirically with household survey data the gainers and losers from price changes can be identified and the magnitudes of their gains and losses measured nonparametric estimation techniques provide a straightforward and convenient way of displaying this information the procedure is illustrated for the effects of rice pricing in thailand using data from more than five thousand rural households estimates of the revenue effects of price reforms are harder to obtain because they require estimates of supply and demand elasticities estimates that are not easily obtained for many developing countries a procedure is presented for estimating price elasticities of demand from spatial price variation as recorded in household survey data the main innovations lie in the appropriate treatment of quality variations and measurement error applications of the procedure in cote d ivoire indonesia and morocco are reviewed

the solaria syndrome social capital in a growing hyper technological economy we develop a dynamic model to analyze the sources and the evolution of social participation and social capital in a growing economy characterized by exogenous technical progress starting from the assumption that the well being of agents basically depends on material and relational goods we show that the best case scenarios hold when technology and social capital both support just one of the two productions at the expenses of the other however trajectories are possible where technology and social interaction balance one another in fostering the growth of both the social and the private sector of the economy along such tracks technology may play a crucial role in supporting a socially sustainable economic growth

marginal commodity tax reforms a survey as noted 30 years ago by martin feldstein optimal taxes may be useless for practical purposes and emphasis should instead be placed on the possibility of enhancing welfare by reforming existing tax rates in this perspective marginal commodity tax reforms are gaining increasing attention due to political and economic constraints on large reforms of direct or indirect taxation in this paper we summarize the main features and results of the literature on marginal commodity tax reforms pioneered by ahmad and stern further developed by yitzhaki and thirsk and recently reinterpreted by makdissi and wodon we establish new links to other fields of research namely the literature on the use of equivalence scales and on poverty measurement we also critically examine some issues associated with the implementation of marginal tax reforms with special reference to the calculation of welfare weights and revenue effects finally we suggest directions for future research on poverty reducing commodity tax reforms

targeting assistance to the poor efficient allocation of transfers when household income is not observed abstract this paper examines the problem of how to transfer money or other forms of assistance to poor households when one observes some characteristics of households but not their incomes this and related issues are often referred to as the targeting problem the paper first sets out the problem formally as one of minimizing a poverty index given a fixed amount of money available for transfers assuming that household survey data are available which include accurate income and or expenditure information the solution for the problem is formulated as a non linear mathematical programming exercise using household survey data from cote d ivoire the technique is applied to both urban and rural areas separately the paper concludes with a general discussion and suggestions for future research

ending food subsidies nutritional welfare and budgetary effects governments faced with growing budget deficits are cutting many social expenditures including costly food subsidy programs that have provided benefits to the rich and poor alike since the poor spend a larger share of their income on food than do the rich these cuts usually have negative distributional welfare and nutritional effects this article discusses the methodological issues in estimating the effects of price and tax reforms in developing countries the author applies a model that deaton developed 1988 to estimate price elasticities from cross section data the only reliable and detailed data available in most developing countries measures of both real income and nutrition are used to evaluate the effects of changes in the moroccan food subsidy program the analysis suggests that subsidies on inferior foods not consumed by the wealthy would reduce the welfare costs to the poor and limit the budgetary expenditures required

tax perceptions and preferences over tax structure in the united kingdom do voters know their tax liabilities accurately or do they systematically misperceive them could such misperceptions influence voters choices over alternative tax structures proposed by politicians this paper assesses the accuracy of individuals tax perceptions in the uk using micro data from the british social attitudes survey 1995 and tests an empirical model of the determinants of tax structure preferences including tax misperceptions a systematic bias towards over estimation of income and expenditure tax vat liabilities is found and individ uals tax preferences appear to be both dominated by self interest and distorted by tax misperceptions whether using a traditional utility maximisation framework or a variety of public choice frameworks economists agree that consumer voters or taxpayer voters dislike taxes taxes lower the consumption possibility set and thereby utility politicians proposing higher taxes expect to lose votes unless they can persuade voters that the utility gain from the use of those taxes will exceed the tax induced utility loss of course the extent of individuals losses will depend on their circumstances and how revenues are raised the tax structure traditional tax incidence and excess burden analyses and models of political costs associated with the tax structure hettich and winer 1984 1988 each provide guidance on the extent to which different individuals may be expected to suffer and vote differently under alternative tax structures much will depend on attitudes towards and perceptions of specific taxes especially personal income taxes and consumption taxes underlying most such analyses are two common presumptions i tax preferences are dictated by self interest and ii individuals accurately assess their tax liabilities and so make informed choices two largely independent areas of literature have challenged these assumptions first models incorporating altruism

the economics of development a survey i the subject our definition of the subject will be the use of economic analysis to understand the economies of poor or developing countries this includes in particular how standards of living in the population are determined and how they change over time and further how policy can or should be used in the influence of these processes the definition contains in principle much or most of analytical methods in economics insofar as they can be put to use in the examination of the issues of interest this is as it should be but it poses a problem for a survey in a journal a comprehensive treatment is infeasible so we shall follow a different route the survey will focus on what i take to be the major themes and approaches which characterise the productive aspects of the subject there is therefore no pretence at being exhaustive the purpose is rather to highlight some of the advances many of these have been of real substance there are a number of possible purposes for a survey and it is important to be clear at the outset for whom it is intended what it is and what it is not this survey is addressed to economists and students of economics who know the tools of their trade but not necessarily how they have been applied to and fashioned for the analysis of the economics of developing countries it is a description of the ways in which problems can be productively formulated and approached in terms of examples chosen for their intrinsic importance and interest the vastness of the subject means that we have to be highly selective it does not seek to provide a summary evaluation of the current view of the appropriate response to immediate policy questions it is not a history of thought nor a research manifesto nor an attempt to adjudicate or settle the major debates where they arise naturally from the major purpose some judgements on these subjects will be offered but they do not themselves constitute the primary intent of this survey there are three lines of enquiry or sets of questions which have i suggest been distinctive of the most fruitful work in development economics they will

measuring globalization of international trade theory and evidence summary measuring globalization requires a standard of perfect international integration as a benchmark that a single world space would reach under conditions of geographic neutrality in international trade we define this standard and present indicators for openness connectedness and integration for each specific economy and for the world economy we apply our indicators to data on trade flows for 59 countries for the 1967 2004 period results show that trade integration is higher than what traditional openness indicators suggest several economies find high levels of integration but the low degree of openness in some large economies jeopardizes the progress of globalization

political regimes and the extractive capacity of governments taxation in democracies and dictatorships recent political and economic transformations in latin america africa asia and eastern europe have brought about a renewed interest in the incentives and capabilities of different types of political regimes to implement policies that are deemed necessary for economic development in particular policies aimed at increasing tax revenue one central question is whether democracies can collect as much in taxes as dictatorships this article addresses this question by examining whether regime type classified as democracy or dictatorship has a causal impact on a government s capacity to mobilize resources through taxation on the basis of data gathered for 108 countries for the period between 1970 and 1990 the article concludes that observed differences across countries regarding the level of taxes collected by the government are not due to the fact that some are under a democracy and others under a dictatorship concerns about the inability of democratic regimes to collect taxes are therefore unfounded

the theory of taxation for developing countries tax policy has far reaching implications for economic development and public administration this book which presents a modern theory of public finance brings together many of the most distinguished economists who have written on the subject they provide coherent principles for tax design and a systematic framework for the analysis of practical questions of tax reform and pricing policy in developing countries the book is especially timely as countries experience increasing shortages of government revenue and the distortions brought about by poorly designed tax systems it pays particular attention to the special problems of developing countries such as the taxation of agriculture the aim throughout is to develop techniques that can be quantitatively applied given the data available and empirical case studies illustrate the methods in action the authors analyze the links between tax theory social cost benefit analysis and the pricing of publicly supplied goods and services they also explore the empirical and econometric problems of identifying the tradeoffs between equity and efficiency other topics treated include the analysis of labor markets the taxation of foreign private investment and of fuel and the pricing of education although the models used concentrate on developing countries most of the methods and discussion apply as well to the problems of more affluent countries

social capital and entrepreneurial activity a pseudo panel approach abstract this paper uses a pseudo panel approach at an age based cohort level to investigate the extent to which social capital accounts for differences in entrepreneurial activities the findings suggest that trust measured by trust either in strangers or in public institutions facilitates entrepreneurship we also find that parents emphasis on individual achievement relative to interpersonal relations in raising their child is positively associated with entrepreneurship evidence suggests that both social norms and networks influence entrepreneurship these results do not change when we use social capital measured at the national level

fiscal faux pas an analysis of the revenue implications of trade liberalization abstract this paper examines the argument that trade liberalization depresses tax revenue gdp ratios in developing countries this occurs because the structural characteristics associated with developing countries limit their ability to make the transition from trade to domestic taxes using a panel of 80 developing and industrialized countries over 1970 98 the econometric analysis carried out employs a fixed effects regression framework to examine the evidence the results indicate that low income and upper middle income countries have experienced declining tax revenues as a result of falling income and trade tax revenues and that structural characteristics have been significant in explaining the decline

the combined incidence of taxes and public expenditures in the philippines incidence studies of fiscal policy in developing countries typically examine either the distribution of tax burdens or the incidence of public expenditures but the central issue for policymakers is the combined or net incidence of fiscal activities one reason that combined incidence studies are so rare is that they require detailed data on both taxation and public spending the authors show that the net incidence of fiscal policy in a country with average data the philippines can be estimated using a variety of data sources and tools using simplifying assumptions for 20 years the philippine economy has experienced a series of balance of payments crises triggered by fiscal crises it has had an unsatisfactory record of poverty alleviation the authors examine net fiscal incidence to find out how poverty will be affected by the rise in taxes and the cut in spending they found that 1 the incidence pattern of taxes is basically neutral contrary to expectations indirect taxes are only slightly regressive and 2 it is the pattern of expenditures that drives the combined incidence which is progressive

a theory of buyer seller networks this paper introduces a new model of exchange networks rather than markets of buyers and sellers it begins with the empirically motivated premise that a buyer and seller must have a relationship a link to exchange goods networks buyers sellers and the pattern of links connecting them are common exchange environments this paper develops a methodology to study network structures and explains why agents may form networks in a model that captures characteristics of a variety of industries the paper shows that buyers and sellers acting strategically in their own self interests can form the network structures that maximize overall welfare

black markets and optimal evadable taxation in a simple model of evadable indirect taxation some surprises emerge because of a market thinning effect of high prices high taxes induce multiple equilibria low price black markets and high price legal markets further evadability introduces a bifurcation to optimal taxation for less effective tax administrations the optimal tax system follows a cash cow pattern with one sector bearing all of the tax but for relatively effective administrations the optimum follows a slightly modified ramsey rule this discontinuity results from the mathematics of evasion incentives and may help explain tax reforms commonly seen over the course of economic development

ethnic ties in trade relationships and the impact on economic performance the case of small scale producers in the handloom sector in ethiopia abstract this article analyses the importance of ethnic ties in trade relationships of small scale producers in the handloom sector in ethiopia using both a non parametric and a parametric statistical method it is shown how various socio economic characteristics of producers lead to ethnic ties with traders it is also shown that ethnic ties affect the performance of producers negatively apparently the positive effect of ethnic ties through the reduction of transaction costs arising from market imperfections does not outweigh the negative effects of closed social networks

from the static to the dynamic some problems in the theory of taxation abstract this paper considers problems and issues that arise when we attempt to extend the static theory of taxation and production planning to a dynamic context and to combine that theory with theories of growth the reasons dynamic theory is less developed include problems with the analytical tractability of even those dynamic models which attempt to retain the basic structure of the static model furthermore difficult and interesting issues arise in a dynamic context which are either not present or are much less severe in the static theory special attention is paid to these new issues and the difficulties they pose

the seesaw principle in international tax policy abstract the standard analysis of the optimal international tax policy of a small country typically assumes that the country either imports or exports capital but does not do both this paper considers the situation in which a small country both exports and imports capital and can alter its tax on one or the other but not both in each case a seesaw relationship is identified in which the optimal tax on the income from capital exports imports is inversely related to the given tax rate on income from capital imports exports the standard results for optimal taxation of capital exports and imports are shown to be special cases of the more general seesaw principle

using survey data to assess the distributional effects of trade policy the author develops and applies a methodology to empirically explore the effects of trade policies on the distribution of income and poverty in developing countries he uses a methodology based on two links one connecting trade policies to prices and another connecting prices to household welfare the author applies the methodology to the study of the distributional effects of mercosur on argentine families the main finding is that mercosur benefits the average argentine household across the entire income distribution there is evidence of a pro poor bias of the regional trade agreement on average poor households gain more from the reform than middle income households whereas the effects on rich families are positive but not statistically significant prior to the reform argentine trade policy protected the rich over the poor and after the reform granted some protection to the poor as relative pre mercosur tariffs are higher on relatively skill intensive goods the tariff removals tend to benefit the poor over the rich these findings indicate that trade reforms may actually help improve the distribution of income and reduce poverty in the country

production risk and the functional distribution of income in a developing economy tradeoffs and policy responses abstract we develop a stochastic endogenous growth model to examine the relationship between the volatility of growth and the factor distribution of income our framework incorporates two important features of developing economies the co existence of a modern and a traditional sector and the fact that the income generated in the traditional sector can escape taxation the relationship between volatility and factor distribution is complex depending upon the source of risk and the elasticity of substitution between capital and labor in the formal sector the policy options available to the government for counteracting changes in volatility are analyzed the second best optimal tax structure is also characterized

maize and the free trade agreement between mexico and the united states setting the price of maize in rural mexico above the world price is inefficient and likely to have negative distributional effects because many subsistence producers and all landless workers are net buyers in fact it screens out the relatively poor rather than the relatively rich the policy objective therefore should be to move toward free trade this would yield large gains in efficiency the free trade agreement provides an ideal opportunity to pursue this objective it will provide freer entrance into the united states for other agricultural products as well as a broad range of manufactured products ensuring secure and sustained access for labor intensive agricultural and manufactured products can help ease the impact on the labor market of a transition away from subsistence maize cultivation

dalton improving tax reform when households differ in ability and needs abstract in a previous paper we suggested a method for identifying tax reforms that adhere to dalton s principle of transfers approving a small enough transfer from rich to poor however even the weak requirement from that method namely prescribing a uni dimensional ordinal ranking of households by how deserving they are of a marginal income transfer is con fining here we extend the approach by formulating a two dimensional criterion for a dalton improving tax reform when there is social approval for transfers when other things are equal from the more able to the less able and from less needy households to more needy ones the possibility of applying this extended criterion in practice and a comparison with other criteria is carried out using the example of u k excise taxes

clustering cooperation and search in social networks the paper discusses the important role of clustering in the evolution of social networks as it affects not only the incentives of players to cooperate but also their ability to search for fresh opportunities depending on the volatility of the environment and the social convention in place we show that network clustering endogenously adapts to achieve and maintain to the extent possible a state of high social connectivity in the long run jel c71 d83 d85

behind the market stage where real societies exist part i the role of public and private order institutions this two part article is an attempt to clarify the social conditions upon which the viability and efficiency of the market system rest it strives to show that the embeddedness thesis that is an explanation based upon the existence of long run personal ties involving the use of reputation mechanisms among transactors cannot fully elucidate the question as to how the problem of trust is solved in market societies as explained in part i there are difficulties of both theoretical and empirical historical kinds and these explain why the market order needs to be sustained by private and public order institutions in part ii the role of generalised morality in backing or supplementing such institutions is discussed in the light of game theory and particular emphasis is put on the ability of moral norms to sustain honest behaviour by generating the right kind of preferences and establishing trust the vexed problem of the dynamics of norm emergence and erosion is then addressed with a view to showing

coordination commitment and enforcement the case of the merchant guild we interpret historical evidence in light of a repeated game model to conclude that merchant guilds emerged during the late medieval period to allow rulers of trade centers to commit to the security of alien merchants the merchant guild developed the theoretically required attributes secured merchants property rights and evolved in response to crises to extend the range of its effectiveness contributing to the expansion of trade during the late medieval period we elaborate on the relations between our theory and the monopoly theory of merchant guilds and contrast it with repeated game theories that provide no role for formal organization

social welfare of alternative controlled price policies recent developments in social welfare analysis provide insights into the selection of price policies in the presen t paper a ces social welfare function and a weighted average of utilitarian and leximin rules are used to identify optimal producer prices in an economy where government is the price setter and agents are risk averse the analysis distinguishes between the interests of commercial producers peasant producers consumers and taxpayers a n application to zimbabwe indicates that a maize producer price in the low medium to medium portion of the historical range would be social ly optimal if egalitarian preferences are moderate this outcome is somewhat insensitive to group weighting schemes and to interpersonal utility correspondences copyright 1993 by mit press

optimum taxation and the allocation of time abstract a theory of optimal taxation is presented building upon becker s 1965 theory of the allocation of time optimal commodity taxation is governed by factor shares in household activities any market good which requires little household time or even saves time should carry a relatively low tax rate this policy rule does not require the estimation of price elasticities and is therefore more applicable than traditional ramsey rule taxation

if agricultural land taxation is so efficient why is it so rarely used the land tax enjoys a distinguished pedigree in the theoretical literature on tax efficiency yet it is rarely used as a serious revenue source in rural areas of developing countries this article considers three drawbacks of the land tax relative to taxes on exports or marketed output 1 capitalization effects of the land tax impose a large burden on the current generation 2 land taxation increases the riskiness of net farmer income and 3 administration of the land tax entails costly informational requirements this article demonstrates that only the second and third drawbacks are valid economic arguments against the land tax simulations based on an economic model of farm behavior suggest that farmers may still prefer a land tax to an export tax despite the increased uncertainty of their after tax income administrative costs are therefore the best explanation of the weak link between the theoretical and practical aspects of land taxation

tax evasion and financial development under asymmetric information in credit markets abstract recent empirical studies have documented that after controlling for variables related to state capacity the incidence of firms tax evasion on their sales is negatively correlated with the level of a country s financial development motivated by this stylized fact our paper takes state capacity as given and provides an alternative theory that is built upon asymmetric information in credit markets particularly within developing economies we analytically show that with a more developed financial sector that exhibits smaller agency costs the government of a rich small open economy country will raise its optimal tax auditing probability which in turn leads to more tax compliance our baseline model also yields an empirically realistic positive correlation between financial development and the ratio of tax revenue over gdp in an extended setting which allows for size dependent probabilities of tax detection we find that consistent with the empirical evidence large firms comply with taxes whereas small firms evade taxes

taxation base in developing countries abstract informal sectors are larger in developing countries than in rich countries this is a result of higher fixed costs of entry into the formal economy in developing countries we show that raising barriers to entry is consistent with a deliberate government policy for raising tax revenue by generating market power and hence rents for the permitted entrants market entry fees foster the emergence of large taxpayers the rents can be readily confiscated by the government through entry fees and taxes on profits at a low administrative cost the relevance of the theory is assessed with a sample of 64 countries empirical analysis supports the results of the paper

second best optimal taxation of capital and labor in a developing economy abstract as commercial integration reduces the reliance on foreign trade taxation raising tax revenue has become a major concern for the governments of developing economies this paper examines how the tax burden in a developing economy should be distributed between capital income and labor income we study a two sector model where the traditional sector is informal and consequently cannot be taxed by the government in this setup we find that the optimal second best tax structure in order to raise a certain amount of revenue requires to tax capital income at least as much as labor income and possibly more

imperfect information and labor market bias against small and medium sized enterprises a korean case we examine the labor market s bias against small and medium sized enterprises focusing on the seoul digital industrial complex case we adopt heckman s approach to control selection bias and use primary data from questionnaire surveys conducted at both firm and employee levels we find that conventional firm specific factors such as wages fringe benefits and weekly work hours primarily explain the labor market bias but imperfect information is also positively associated with the bias for example a firm s inadequate ability to identify a pool of potential employee candidates or to provide them comprehensive firm or job specific information tends to worsen labor shortages and an employee s ex ante incomplete knowledge of on the job training or education opportunities tends to increase ex post turnover intentions our results suggest that reducing the market bias requires improving imperfect information as well as conventional firm specific conditions

optimal taxation and optimal tax systems the theory of optimal taxation has for the pas two decades been the reigning normative approach of taxation this paper argues that in its current state optimal tax theory is incomplete as a guide to action concerning many critical issues in tax policy it is incomplete because it has not yet come to terms with taxation as a system of coercively collecting revenues from individuals who will tend to resist the coercive nature of collection taxes implies that the resource cost of implementing a tax system have been and will continue to be a critical determinant of appropriate tax policy the paper first presents the three cornerstone propositions of optimal tax theory and then it discusses the influence of these propositions on recent tax policy developments it concludes by sketching an alternative to optimal taxation called the theory of optimal tax systems which embraces the insights of optimal taxation but also considers the technology of raising taxes and the constraints placed upon tax policy by that technology the optimal tax systems perspective is shown to shed light on the choice of tax instruments the problem of tax evasion and the appropriate tax treatment of capital income this abstract was borrowed from another version of this item

optimal trade taxes on agriculture in developing countries subsistence foodcrops and incomes are hard to tax in developing countries it is easy and common to tax agricultural imports and exports if domestic transactions cannot be taxed how should agricultural trade taxes be set and how should indirect taxes on nonagricultural consumer goods be set this paper derives and quantifies formulas for the optimal export tax on a nonfood agricultural product ghanaian cocoa in which the country has market power and the level of indirect taxes on taxable consumer goods it asks whether starting from free trade on cereals there should be import tariffs or subsidies copyright 1990 by royal economic society

the design of fiscal reforms in revenue constrained developing countries while generalisation is perilous there are many especially small developing countries for which sales taxes and turnover taxes are fairly negligible as revenue sources and for which import duties and export taxes particularly the former are leading revenue sources for evidence from the early i980s see tanzi i987 and greenaway and milner i990 this observation is unsurprising when account is taken of the administrative constraints to which many developing countries are subject sales taxes can be difficult to collect not to mention a complex tax like vat income tax is largely infeasible and often has to take a simple form such as a payroll tax confined in practice to public and large company employment some taxes which would be assumed to be eminently feasible in industrial economies may not generate as much revenue as might be supposed in a developing country for instance tax disks which the law may require heavy goods vehicles to carry may generate a flow of bribes to police and other officials if these are wise enough to set the bribe at a modest level making it cheaper to pay bribes than to buy a disk a cynic might say that the bribes are an unofficial source of revenue if their existence enables the state to get away with paying its officials absurdly low salaries one would have to hope if that argument is accepted that the officials do something socially useful apart from stopping heavy goods vehicles such considerations make it interesting to consider the design of public finance for a country severely constrained in its choice of what musgrave called tax handles that is types of tax instrument which it may practically employ the existing literature for which newbery and stern i987 provides an excellent review throws some light on this issue but the problem is seldom treated explicitly an exception would be dreze and stern i985 whose highly abstract and general treatment of cost benefit analysis theory can be seen to incorporate principles of public finance which fully cover the restricted policy choices which i have in mind because the approach of these authors is so general however it is not easy to extract conclusions for tax design in specific cases this is no criticism of the paper of course as the argument is addressed to cost benefit analysis generally speaking theory has developed in the direction of sophisticated and complex tax systems the next section discusses why this is so from the point of view of theory yet ideal tax systems would be difficult to implement in many developing countries as i shall treat tariffs as a highly feasible revenue

agricultural policies in the presence of distorting taxes this article analyzes how distortionary factor taxes affect the welfare impacts of production subsidies production quotas acreage controls subsidies for acreage reductions and cash transfers to farmers pre existing taxes substantially raise the costs of all these policies these additional costs reflect the welfare losses from financing certain policies by distortionary taxes they also reflect interactions with factor markets caused by changes in the costs of producing agricultural output previous studies ignore the latter types of effect consequently they significantly overstate the costs of production subsidies and understate the costs of production quotas acreage controls and subsidies for acreage reductions

introduction tax policy issues for the 1990s in recent years in the wake of fiscal crisis developing countries have increasingly begun to restructure their tax systems to seek higher revenues or to improve the revenue elasticity and buoyancy of the tax structure chhibber and khalilzadeh shirazi 1988 these reform movements have also aimed to eliminate the disincentive effects of onerous levels of taxation to reduce the economic inefficiencies induced by the distortionary taxation of assets and sectors to protect the poorest of the poor from the tax net and to provide partial relief from the unwelcome effects of inflation this introduction to the following articles on tax policy first gives an overview of tax reform in developing countries it then distills lessons for tax reform from past developing country experiences and reviews selected issues that are expected to dominate tax policy research and discussions in the 1990s the five other articles in this symposium provide an in depth review of applications of tax policy models in developing countries and analysis of tax policy toward foreign direct investment taxation of agricultural land and financial assets and the redistributive impacts of various taxes

incentives information and organizational form we model an organization as a hierarchy of managers erected on top of a technology here consisting of a collection of plants in our framework the role of a manager is to take steps to reduce the adverse consequences of shocks that affect the plants beneath him we argue that different organizational forms give rise to different information about managers performance and therefore differ according to how effective incentives can be in encouraging a good performance in particular we show that under certain assumptions the m form multi divisional form is likely to provide better incentives than the u form unitary form because it promotes yardstick competition i e relative performance evaluation more effectively we conclude by presenting evidence that the assumptions on which this comparison rests are satisfied for chinese data

industry institutions social capital and firm participation in industrial development industry institutions and trade associations represent the collective interests of an industry s constituent firms and play a prominent role in industrial development yet the strength and efficacy of industry institutions to promote these collective interests depends upon the active support and participation of member firms this is essentially a collective action problem by aligning olson s 1971 logics of collective action framework with nahapiet and ghoshal s 1998 dimensions of social capital this article uses survey data from 381 firms from across five uk manufacturing sectors to explore the factors that affect the propensity for firms to participate in industry institution led initiatives the results suggest the propensity of firms participating in collective activities rises where shared interests emerge although the over riding factor is the extent to which firms perceive their own ability to influence and shape the direction of such activities the logic of influence

the incidence of agricultural policies abstract a general equilibrium model is used to analyze agricultural policy incidence in the presence of distortionary income taxation the incidence of lump sum transfers to farmers supply control through input retirement and production subsidies are considered partial equilibrium incidence calculations are shown to systematically overstate the benefits farmers receive from farm programs kaldor s compensation test is used to judge the relative efficiency inefficiency of alternative farm programs at the margin supply control through input retirement may dominate decoupled lump sum transfers if the tax system is very inefficient and subsidy payments are high

land taxes output taxes and sharecropping was henry george right economists have generally argued that if a land tax is administratively feasible then to increase efficiency it should be used to the exclusion of output taxes this article shows that underlying this policy prescription is the assumption that institutions for pooling and spreading production risks are perfect when account is taken of the imperfections in those institutions some use of output taxes will be pareto superior to a pure land tax regime and may induce higher output as well henry george was wrong these results generally apply even when the land tax is indexed to regional output and when land is farmed under sharecropping even in these cases a move from a pure land tax to a mix of land and low output taxes will reduce pre existing distortions in both consumption and production arising from the imperfection in risk markets

pareto efficient international taxation this paper analyzes pareto efficient international tax regimes because every country faces its own national budget constraint the diamond mirrlees production efficiency theorem which underlies key tenets of policy advice in international taxation the desirability of destination basis for commodity taxation of the residence principle for capital income taxation and of free trade does not apply the paper establishes conditions relating to the availability of explicit or implicit devices for reallocating tax revenues across countries under which production efficiency is nevertheless desirable and characterizes the precise ways in which pareto efficient international taxation may require violation of established tenets

welfare impacts of china s accession to the world trade organization data from china s national rural and urban household surveys are used to measure and explain the welfare impacts of changes in goods and factor prices attributable to accession to the world trade organization wto the price changes are estimated separately using a general equilibrium model to capture both direct and indirect effects of the initial tariff changes the welfare impacts are first order approximations based on a household model incorporating own production activities calibrated to household level data and imposing minimum aggregation the results show negligible impacts on inequality and poverty in the aggregate however diverse impacts emerge across household types and regions associated with heterogeneity in consumption behavior and income sources with possible implications for compensatory policy responses

agricultural taxation in developing countries a survey of issues and policy this study surveys the experience of agricultural taxation in developing countries in the context of the ongoing policy debate about the tax structure and administration affecting agricultural producers using the examples of a number of countries it analyzes the conceptual and practical problems associated with different tax regimes governments in most countries have reduced indirect export taxes on agricultural producers however the revenue from direct taxes on farmers has not increased a major problem in most countries has been the measurement of actual agricultural income different measures for presumed income have been used with varying success they seem to have the most potential for increased revenue in many countries but their effective implementation is constrained by the political and administrative considerations

social capital inclusive networks and economic performance abstract empirical studies show that the relationship between social capital and economic performance is ambiguous the paper points to the potential trade off between the sustainability of self enforcement and the magnitude of gains from trade in social networks as an explanation based on an infinitely repeated multi player prisoners dilemma it is shown how self enforcement of cooperation within a network is influenced by its inclusiveness its communication capacity and the complexity of the exchange setting the paper shows that inclusive social capital can combine both low enforcement costs and high gains from trade even in a complex exchange setting
