addiction compulsion and the technology of consumption the consumption technology model of lancaster and becker is extended to include addictive activities assuming a utility function in which the individual places a premium on maintenance of self esteem the model generates empirically verified patterns of habituation withdrawal and the compulsive restarting of an abandoned habit it is then applied to the analysis of public policies toward drug abuse their frequent ineffectiveness is shown to result from an unwarranted emphasis on deterring the addictive activity rather than on encouraging atceptable behavior

agricultural protection in developing countries countries often have a jekyll hyde relationship with their agricultural sector policymakers both tax and subsidize agriculture in the early stages of a country s development policy makers exploit agriculture through export taxes and overvalued exchange rates in contrast agricultural policy in advanced industrial countries has strongly protected domestic producers by means of trade restrictions direct price or income supports and public investment this paper explores why farmers are taxed in poor countries and subsidized in rich countries using the economic theory of contests to come to an understanding of the incentives for agricultural protectionism we first sketch a framework for an excludable and rivalrous rent we then apply this framework to agricultural protectionism in developing countries

on the transmission of world agricultural prices two questions are asked about the relationship between domestic prices and world prices of agricultural commodities are variations in world prices transmitted to domestic prices domestic prices are regressed on world prices in various forms taking into account the possible effects of exchange rates and inflation the empirical analysis is based on data from the food and agriculture organization of the united nations for 58 countries from 1968 78 and for the countries of the european community from 1961 85 the results show that most of the variations in world prices are transmitted and that they constitute the dominant component in the variations of domestic prices

what price drug use the contribution of economics to an evidence based drugs policy abstract this paper presents a review of the recent economics literature in the area of illicit drug use particular attention is paid to the economics of addiction and the rational addiction model the welfare economics framework for analysing the social costs of drug use and the attempts that have been made by economists to evaluate recent or proposed policy interventions a dominant theme in this review is the problem of poor data availability this is particularly true when it comes to implementing the rational addiction model but it is also apparent in the literature on estimating the costs of illicit drug use to society as a whole one of the main conclusions of this review is that until recently public policy has not been particularly influenced by research carried out by economists it is not clear whether this is because economists have had to grapple with inadequate data and hence their conclusions are couched in uncertainty or whether it is because drugs researchers have assumed a very limited role for economists in their analysis

distorted agricultural incentives and economic development asia s experience earnings from farming in many low income countries have been depressed by a pro urban bias in own country policies as well as by governments of richer countries favouring their farmers with import barriers and subsidies both sets of policies reduce national and global economic welfare the rapid development of many asian emerging economies has been accompanied by a gradual reduction in their anti agricultural policies but many distortions remain and some countries have moved from negative to positive assistance for farmers following the earlier examples of first japan and then korea and taiwan drawing on results from a new multi country research project this paper examines the extent of these changes relative to those of other developing countries over the past five decades it concludes by pointing to prospects for further policy reform in asia

the political economy of regulations and trade wine trade 1860 1970 dramatic changes in the 1860 1970 wine trade provide insights on the political economy of regulations and policy instrument choice and trade an invasion of phylloxera in the 1870s turned france from the world s leading exporter to a massive importer of wine and grapes when french production recovered a combination of tariffs safety regulations and quality standards were introduced to protect its french producers causing dramatic changes in global wine and grape production and trade including in spain italy turkey greece algeria tunisia and morocco changes in wine regulations were caused by relative income and loss aversion factors in political economy tariffs were the preferred policy instruments as they directly restrict imports bring in revenues have low transaction costs and are preferred political instruments when there are information imperfections safety regulations and quality standards including labelling and input prohibitions reduce asymmetric information for consumers or undesirable externalities and simultaneously protected domestic producers regulations were often targeted at imported products wine and raisins when tariffs were ineffective or constrained by institutions such as on colonial wine hence tariffs and quality regulations were jointly used in wine policy both as complements and as substitutes in policy design

political economy of public policies insights from distortions to agricultural and food markets the agricultural and food sector is an ideal case for investigating the political economy of public policies many of the policy developments in this sector since the 1950s have been sudden and transformational while others have been gradual but persistent this paper reviews and synthesizes the literature on trends and fluctuations in market distortions and the political economy explanations that have been advanced based on a rich global data set covering a half century of evidence on commodities countries and policy instruments the paper identifies hypotheses that have been explored in the literature on the extent of market distortions and the conditions under which reform may be feasible

fiscal interactions of central city and suburbs the case of zurich one possible explanation for the migration from the central city to fiscally independent suburbs is a lack of equivalence between taxation and perceived benefits from local public goods spill outs to suburbs add to this process and may lead to fiscal erosion of the central city piecemeal evidence is presented that this problem applies to the city of zurich various possible remedies are discussed one of which has been applied in zurich though not successfully it is shown theoretically and empirically why this failure occurred alternative countermeasures are suggested and an account of how zurich government officials reacted is supplied

economic development institutional change and the political economy of agricultural protection an econometric study of belgium since the 19th century this empirical study uses 100 years of annual data on 11 agricultural commodities from belgium to measure the impact of structural changes coinciding with economic development and changes in political institutions on agricultural protection the analysis shows that changes in agricultural protection are caused by a combination of factors governments have increased protection and support to farmers when world market prices for their commodities fell and vice versa offsetting market effects on producer incomes other economic determinants were the share of the commodities in total consumer expenditures negative effect and in total output of the economy positive effect with belgium a small economy there was no impact of the trade position changes in political institutions have affected agricultural protection democratic reforms which induced a significant shift in the political balance towards agricultural interests such as the introduction of the one man one vote system led to an increase in agricultural protection the integration of belgian agricultural policies in the common agricultural policy in 1968 coincided with an increase in protection ceteris paribus both institutional factors related to changes in access to and information about the decision making at the eu level and structural changes in the agricultural and food economy may explain this effect

rational addiction and the effect of price on consumption legalization of such substances as marijuana heroin and cocaine surely will reduce the prices of these harmful addictive drugs by the law of the downward sloping demand function their consumption will rise but by how much according to conventional wisdom the consumption of these illegal addictive substances is not responsive to price however conventional wisdom is contradicted by becker and murphy s 1988 theoretical model of rational addiction the becker murphy b m analysis implies that addictive substances are likely to be quite responsive to price in this paper we summarize b m s model of rational addiction and the empirical evidence in support of it we use the theory and evidence to draw highly tentative inferences concerning the effects of legalization of currently banned substances on consumption in the aggregate and for selected groups in the population addictive behavior is usually assumed to involve both reinforcement and tolerance reinforcement means that greater past consumption of addictive goods such as drugs or cigarettes increases the desire for present consumption but tolerance cautions that the utility from a given amount of consumption is lower when past consumption is greater these aspects of addictive behavior imply

subjective and objective measures of governmental regulations in oecd nations abstract since government regulations may have an important impact on the macroeconomic performance of market economies it is necessary to devise quantitative indicators of the regulatory regime which raises some difficult methodological issues after reviewing some of these problems we compare the results of several recent quantitative studies of regulation in oecd nations some based on an extensive review and quantification of laws and regulations others based on observational data of those familiar with these regulations despite their very different methodologies and coverage of particular types of governmental regulation the results of the three studies are significantly correlated which suggests that they all capture the same underlying reality

targeting maps an asset based approach to geographic targeting summary proper targeting of policy interventions requires reasonable estimates of the benefits of the alternative options to inform such decisions we develop an integrated approach stemming from the small area estimation literature that estimates the marginal returns to a range of assets across geographically defined subpopulations we create a series of maps that can be overlaid with traditional poverty maps to identify strong candidate areas for intervention though an efficiency equity tradeoff sometimes exists we apply our method using recent ugandan data results are consistent with independent empirical findings and suggest asset specific transfer schemes would improve with a spatially targeted strategy

china s uneven progress against poverty while the incidence of extreme poverty in china fell dramatically over 1980 2001 progress was uneven over time and across provinces rural areas accounted for the bulk of the gains to the poor though migration to urban areas helped the pattern of growth mattered rural economic growth was far more important to national poverty reduction than urban economic growth agriculture played a far more important role than the secondary or tertiary sources of gross domestic product gdp rising inequality within the rural sector greatly slowed poverty reduction provinces starting with relatively high inequality saw slower progress against poverty due both to lower growth and a lower growth elasticity of poverty reduction taxation of farmers and inflation hurt the poor external trade had little short term impact

issues relating to agricultural pricing policies and their analysis in developing countries abstract agricultural pricing policies in developing countries are often the result of complex interactions between producer consumer and merchant groups and their relative effectiveness in influencing government decision making even within governments various ministries often have opposing views in this environment one of the contributions a policy analyst can make is to attempt to quantify the effects of different policy options this permits a more informed discussion which hopefully leads to better decision making and an improved incentive environment many analyses of agricultural pricing policies have used the standard partial equilibrium analysis where no linkages between commodity markets were considered in this paper we have considered cross price effects also we have discussed issues relating to other adjustments refinements of the standard method so that a practitioner not familiar with the various methods can form an opinion of what the options are and what adjustments may be appropriate for a particular case in question the adjustments relate to overvaluation of currencies input price distortions differences in the degree of distortions between producers and consumers and variability of border prices the inclusion of cross price elasticities was important for assessing production consumption and trade effects for argentina but for the other countries it resulted in only somewhat improved accuracy the adjustment for exchange rates had a large impact in egypt and was important for other countries as well this underlines the importance of exchange rates as key variables for agricultural pricing policies in general the numbers show that the traditional taxation policies of agricultural products in the sample of developing countries is somewhat less widespread than in the past these policies however continue to favor consumers over producers with significant losses for some of the latter the large size of welfare losses especially compared to efficiency losses highlights the importance of correcting distorted prices that adversely affect the poorest sections of society also the usual government objective of taxing producers to raise revenues is frequently defeated by the large subsidies provided to consumers for the partitioner for whom time is often of the essence the assessment of welfare effects using the partial equilibrium method may provide reasonably good first cut estimates of the order of magnitude of the impact of distortions but often these base case estimates can and should be adjusted for a number of possible factors the analyst needs to determine how important accurate estimates of key variables are to the policy makers he or she then needs to compare the costs involved in generating or gathering the data and doing the calculations with the benefits of a broader and more accurate analysis of the distortionary effects of the particular case in question

drug policy and federalism supply restricting drug policy is inefficient from an economic point of view but is nevertheless widely used this paper explains this phenomenon as individually rational behavior for local government because supply restriction gives addicts an incentive to migrate it has an external effect this effect makes a policy of supply restrictions individually rational but leads to socially wasteful competition between local governments in a federal system

explaining the relative decline of agriculture a supply side analysis for indonesia the relative decline of agriculture in growing economies is a central feature of economic development and a major influence on agricultural policies the literature on the causes of this decline has focused on the relative price effects arising from demand factors especially engel s law rather than on supply side influences such as changes in relative factor endowments and differential rates of technical change this article develops a simple structural model of the transformation of the indonesian economy applying an error correction mechanism to capture the dynamics resulting from disequilibria and the costs of adjustment the decline in agriculture s share of gross domestic product is found to be caused much less by the relative price effects typically emphasized in the literature than by capital accumulation and rapid technical change in agriculture

unpacking the meaning of market access evidence from rural kenya summary this paper critically examines the dimensions of market access using farm panel survey data from kenya we investigate changes in ten indicators of market access during the 1997 2010 post liberalization period we find major improvements in certain market access conditions and little change in others there is generally low correlation between alternative indicators of market access all purpose indicators may not accurately reflect specific market access conditions of interest distances to physical infrastructure are often not representative of farmers access to markets changes in specific market access conditions may have more to do with the behaviors of marketing agents we consider the implications of these findings for agricultural marketing policies and for research methods

food security policy options for china lessons from other countries the authors gratefully acknowledge financial support from the world bank and australia s rural industries research and development corporation

food security and agricultural protection in south korea south korea has been pursuing food self sufficiency using high tariffs and high administrative prices in key agricultural and food markets using a dual approach to trade and trade restrictiveness indices we analyze the impact of these market distortions on welfare and trade volume then we compute second best distortions which minimize the welfare cost of meeting observed levels of self sufficiency and production we rationalize these second best distortions to what could be claimed as legitimate protection under a food security fs box in world trade organization wto negotiations fs box protection is sensitive to changes in the definition and the extent of the fs objectives we show that fs via production targets and reliance on imports would be more palatable to consumers and trade partners while preserving income transfer to the farm sector the republic of korea has supported its agricultural sector at a relatively high level compared to that of other member countries of the organisation for economic cooperation and development oecd public intervention mainly consists of high production prices supported by government purchases together with high tariffs that protect domestic producers from foreign competition and implicitly tax consumers trade liberalization recently took place in certain sectors and korea is now a major importer of oilseeds and coarse grains however korea only reluctantly exposed its agricultural sector to the provisions of the uruguay round agreement on agriculture uraa iatrc 1997 it has kept very high tariffs in the rice meat and dairy sectors high production subsidies in most other sectors and significant nontariff trade barriers on many commodities including administra

the price elasticity of opium in taiwan 1914 1942 abstract between 1895 and 1945 the japanese colonial government virtually eliminated opium use in taiwan by licensing and treating existing users prohibiting sales to others and raising the price we evaluate these policies using a two part model to describe the fraction of the population using opium and consumption among users and the rational addiction model by becker et al 1991 we confirm that opium is addictive and find no evidence supporting the rational addiction hypothesis demand is price elastic with estimated short and long run demand elasticities of 0 48 and 1 38 these results have implications for control of other addictive substances

on why agriculture declines with economic growth abstract when economic growth is characterised by a slow rise in the demand for food and rapid growth in farm relative to non farm productivity it is understandable that agriculture in a closed economy declines in relative terms as that economy develops but why should agriculture decline in virtually all open growing economies as well including those able to retain a comparative advantage in agricultural products a key part of the answer is that the demand for non tradable goods tends to be income elastic so resources are diverted to their production even in open economies

taxation or regulation looking for a good anti smoking policy abstract this paper investigates the relative ability of two anti smoking policies taxes and regulation in inducing reductions in cigarette consumption and in providing incentives to stop smoking or not to start to our results based on canadian data show that cigarette demand responds to taxes elasticity of 0 28 but not to regulation while the converse is true for the proportion of smokers in the population

information asymmetry and international strategic alliances abstract this paper examines how information asymmetry affects cross border strategic alliance formation by us firms over the period 2000 2008 we construct a measure information costs based on both geographical distance and the proportion of worldwide gdp the partner s home country represents consistent with our expectations we find an inverse association between information costs and cross border strategic alliances when considering the proportion of alliances formed with publicly quoted overseas partners we find this is unaffected by the level of information costs but rather the level of stock market development tax rate and general economic conditions information costs are however significantly negatively related to alliances with overseas private organizations our results offer clear support for the on going importance of information asymmetry in corporate decision making

tax harmonization and tax competition in the european union lessons from switzerland abstract this paper presents empirical evidence on individual income tax competition in switzerland tax competition has some influence on the spread of people with high income over the cantons and it is partly capitalised in dwelling rents however it neither leads to a collapse of public good supply nor makes redistribution by the fiscal authorities impossible thus if tax competition works well in switzerland there is no reason why it should have disastrous effects in a future european union

targeting public investments by agro ecological zone to achieve growth and poverty alleviation goals in rural india abstract this paper shows that improved technology and rural infrastructure have made important contributions to agricultural growth and poverty reduction in india however these effects have varied widely across agro ecological zones in the past the government has devoted more resources to irrigated areas and this has led to significant production growth and poverty reduction in those areas however as investments in irrigated areas continue to increase their marginal returns diminish and it is now in many of the rainfed areas including some of lower agricultural potential where the marginal returns from additional government investments in technology and infrastructure are largest

a theory of rational addiction we develop a theory of rational addiction in which rationality means a consistent plan to maximize utility over time strong addiction to a good requires a big effect of past consumption of the good on current consumption such powerful complementarities cause some steady states to be unstable they are an important part of our analysis because even small deviations from the consumption at an unstable steady state can lead to large cumulative rises over time in addictive consumption or to rapid falls in consumption to abstention our theory also implies that cold turkey is used to end strong addictions that addicts often go on binges that addicts respond more to permanent than to temporary changes in prices of addictive goods and that anxiety and tensions can precipitate an addiction

local governance and the quality of local infrastructure evidence from village road projects in rural china abstract research has shown that allowing local communities to elect their own leaders increases local infrastructure investment however much less is known about the effects of local governance reform on the quality of local infrastructure this paper examines the effects of governance reform implemented in rural chinese villages on the quality of village road projects we conduct surveys in 101 rural villages and collect data related to the implementation of the reform over the last two decades we also measure the quality of over 550 village road projects completed in these villages using fixed effects and instrumental variable estimation methods we find that the implementation of village governance reform increases the quality of village road projects we also find evidence supporting the following effect mechanisms 1 village leaders become younger and more educated 2 high quality road projects increase incumbent leaders re election chances and 3 village residents participate more actively in the management and monitoring of village road projects

agricultural growth poverty reduction and agro ecological zones in india an ecological fallacy abstract in an article in this journal that is part of an oevre that has been widely cited shenggen fan peter hazel and t haque 2000a present evidence that government investments in india now have greater effects on poverty in rainfed than irrigated regions this note suggests that parts of the methodology on which this claim is based are unclear and possibly suffer from an ecological fallacy even after clarification of their method by the authors some doubts remain as to whether the results quoted support the original claim

lobbying incentives and the pattern of protection in rich and poor countries in seeking to explain why poor countries tend to choose policies that tax agriculture relative to manufacturing while rich countries do the opposite archetypical parameters for a poor agrarian economy and a rich industrial one are inserted in a computable general equilibrium model to simulate the medium term effects on income distribution of policies that distort the relative prices of tradables the model includes a non tradables sector and intermediate inputs realistic features that ensure even greater skewness in the distributional effects of protection than simpler models suggest the magnitude of the results helps explain the tendency for countries to change gradually from taxing to subsidizing agriculture relative to manufacturing as their economies develop the paper draws out the implications of the analysis for agricultural and trade policy reform in the 1990s this abstract was borrowed from another version of this item

effectiveness of regulatory interventions on firm behavior a randomized field experiment with e commerce firms economic regulators use various instruments to stimulate smes to change their behavior but limited evidence exists on the effectiveness of such interventions we analyze the effectiveness of three ways of providing e commerce firms guidance about the legal rules on information disclosure the initial non compliance is considerable in two interventions firm specific guidance is given by post mail and by e mail respectively in another intervention guidance on industry level is given by means of dedicated publications and presentations in all cases the guidance was given on behalf of the regulatory authority the effectiveness of the firm specific guidance is measured through a randomized field experiment while for the industry guidance a panel analysis is conducted we find that sending the firms a letter by post mail slightly improved firm compliance but overall the various forms of guidance appear to be ineffective although information related interventions are commonly used in practice such regulatory interventions can fail to influence the behavior of smes

paradoxical effects of drug policy in a model with imperfect competition and switching costs this paper presents a stylized model of the market for hard drugs we assume that there is imperfect competition that the demand side is dominated by addicts and that the presence of switching costs leads to consumer loyalty drug policies affect the values of the parameters of the model including the degree of consumer loyalty and the static price elasticity of demand taking into account these effects it is shown that tough policies may lead to an increase in the marketing activities by suppliers and cause a long run increase in the number of addicts and total consumption

productivity transport costs and subsistence agriculture abstract a defining feature of many poor economies is the large fraction of workers engaged in subsistence agriculture we develop a multi sector multi region model of a poor economy in which it is costly to transport goods across regions in order to study this outcome a key finding is that higher transport costs drive up the size of the agricultural workforce and the fraction in subsistence in a calibrated version of our model we show that the effect of transport productivity is quantitatively important in terms of both allocations and welfare

dynamic instability of a mixed city in the presence of neighborhood externalities it has been often asked whether a city currently accommodating a variety of economic social and racial groups will continue to be a mixed city or will become exclusively occupied by a single group particularly poor blacks with all other groups moving out of the city in the long run in order to answer this question properly it seems essential to develop a long run dynamic model of a city with emphasis on socioeconomic factors like neighborhood externalities within or among various groups of residents as well as spatial factors like the individual choice of residential space and location it might be safely said that in the literature the only theoretical work which employs a long run dynamic approach to this kind of problem is a paper on dynamic models of segregation by thomas schelling 197 1 although his socioeconomic analysis has revealed some of the dynamic properties of a racially mixed area with neighborhood externalities his model itself is quite unsatisfactory from the economic point of view since it lacks individual utility functions and thereby disregards the aspect of the individual choice of space and location within the city 2 as a result he failed to analyze the effect of spatial segregation within the city on the long run nature of the residential composition of the city in this paper i develop a long run dynamic model of an open city which accommodates two groups of households for example blacks and whites rich and poor young and old with their utility functions depending on a consumption good and residential space i also assume two kinds of neighborhood externalities the first is called negative intergroup externalities that is the utility level of a typical household in one group is adversely affected by an increase in the number of households in the other group living in the city the second is called positive intragroup externalities that is the utility level of a typical household in one group is positively affected by an increase in the size of its own group in in the city first i define a mixed city equilibrium as a long run equilibrium which allows the two groups to coexist in the city in the long run and then introduce a dynamic adjustment process of household movement into and out of the city it is proved that the mixed city equilibrium is always unstable in the presence of negative intergroup externalities and or positive intragroup externalities if residential land is perfectly homogeneous and there is no differential transport cost incurred within the city it turns out however that in the case of a monocentric city with positive transport cost the mixed city equilibrium may be stable or unstable depending on the degree of neighborhood externalities because of the stabilizing effect of spatial segregation between the two groups within the city

the demand for illicit drugs i introduction illicit drug use and alcohol abuse imposes significant costs on society and on the individual users these costs include increased crime health problems and employment problems because of these considerable costs government at all levels has made drug control and the control of alcohol abuse important priorities the federal government has undertaken an aggressive program of interdiction of drug shipments and eradication of drug crops in the field the federal government and the state governments have also increased their criminal justice efforts in analyzing the effect of government drug control programs economists have applied the conventional supply and demand model to illicit drug markets the model includes a demand function that is downward sloping with respect to price and a supply function that is upward sloping or horizontal with respect to price drug programs like interdiction and drug sanctions are assumed to reduce supply and raise equilibrium price other policy options such as some form of drug legalization could increase supply and reduce equilibrium price the effect of these policies on equilibrium quantity is dependent on the elasticity of demand and on whether demand shifts since not much is known about drug price elasticities the potential effects of various drug control policies remain a speculative exercise the purpose of this paper is to estimate the effects of alcohol and drug prices on alcohol use and drug participation both own price and cross price effects are estimated there are few prior empirical studies of the effect of drug prices because data have been difficult to acquire this paper makes use of newly available data on drug prices and is the first paper to link these data to a nationally representative drug use data set of 49 802 individuals estimates of drug price elasticities are important empirical evidence that drug sales can be characterized by market forces drug price elasticities are also important in estimating the likely impact of policies that affect drug prices and in estimating the effects of drug prohibition cross price elasticities are important to estimate since they suggest the likely effects of policies such as an increase in alcohol taxes on illicit drug participation and the effects of marijuana decriminalization on alcohol cocaine and heroin use ii prior studies while there are a number of prior studies of the effects of alcohol prices and policies there are few prior studies of drug prices and polices the reason for so few prior drug studies is the limited amount of data on drug prices and the limited options for linking these data to an individual record by residential area this study uses a new data set of cocaine and heroin prices from the drug enforcement agency that was linked to individual records by the office of applied studies at the substance abuse and mental health services administration leung and phelps 1993 provide a review of a number of recent alcohol demand studies the empirical literature provides considerable evidence that shows increasing the price of alcoholic beverages to decrease alcohol use alcohol demand studies generally estimate price elasticities for beer wine and spirits separately most studies employ aggregate data but a few use individual data studies using aggregate data find price elasticities for beer from about 2 to about 1 0 for wine from about 3 to about 1 8 and for spirits from about 3 to about 1 8 studies using individual data estimate price elasticities for beer from about 5 to about 3 0 for wine at about 5 and for spirits from about 5 to about 4 0 the few prior studies of the effect of decriminalization on marijuana use generally find that marijuana decriminalization has no effect on participation pacula 1994 thies and register 1993 dinardo and lemieux 1992 and johnston o malley and bachman 1981 all used samples of young people and found no effect of marijuana decriminalization

economic structure and the politics of sectoral bias east asian and other cases governments of poor countries generally practise urban biased policies that penalise the agricultural sector to the advantage of non agriculture conversely governments of rich countries generally practise rural bias as south korea and taiwan have become relatively wealthy over recent decades they have also shifted from urban biased to rural biased policies adherents of the rational choice approach to political analysis claim to provide an explanation of the causes of this pattern this explanation is based on changing patterns of political interests and coalition forming possibilities induced by the changes in economic structure characteristically associated with economic growth an evaluation of this claim in the light of the south korean and taiwanese cases suggests that a it has considerable validity although its explanatory power is easily exaggerated b a satisfactory rational choice approach would encompass a wider range of political actors than has been incorporated in existing analy

the microeconomics of the developmental paradox on the political economy of food price policy abstract a longstanding puzzle in comparative economics is the developmental paradox the tendency for government support for agriculture to increase with national income and to decrease with the proportion of economic activity and of the population in agriculture this paper offers a microeconomic explanation for that puzzle it establishes analytically the microeconomic basis for coalition alignments with respect to food price policy then numerically simulates the comparative static effects of alternative food policies on coalition structure a parsimonious household model applied to a heterogeneously endowed society demonstrates how variation in individual welfare effects might beget distinct coalitions in the debate over food price policy and how those policies are inextricably linked to land population and technology policies in food agriculture moreover coalition alignments on particular policy debates are path dependent in particular food price policy creates its own political support

the road to specialization in agricultural production evidence from rural china summary many rural poor in developing countries live in areas far away from markets and isolation is a key limiting factor to their livelihood in this paper we use four waves of a primary panel household survey conducted in 17 remote natural villages in china to study how road access shapes farmers production patterns input use and rural poverty we adopt a difference in difference approach by comparing the outcomes of the households in villages with and without road access before and after the introduction of each road our results show that access to roads facilitates specialization in agricultural production in natural villages with better road access farmers plant fewer numbers of crops purchase more fertilizer and hire more labor consequently road connections improve household agricultural income and reduce poverty in addition road access significantly increases local nonfarm income for the relatively poor households but not the rich overall our research provides empirical justification on the importance of rural road on agricultural specialization and poverty reduction especially in isolated and impoverished regions

growth the external terms of trade and endogenous trade liberalization we study the effects of growth and changes in the external terms of trade on protection there are two sectors an urban sector and a rural sector and trade policy is used to redistribute income between them we show that growth precedes trade liberalization in addition we find that trade reform is triggered by falls in the world prices of primary exports or intermediate imports these results are shown to hold for tariffs and quotas

entrepreneurial police and drug enforcement policy the hypothesis that drug enforcement is relatively high in local jurisdictions where state laws dictate that police retain seized assets is tested in the context of a reduced form equation of the supply and demand for drug enforcement the results are robust across model specifications some of which directly control for the level of drug use legislation permitting police to keep seized assets raises drug arrests as a portion of total arrests by about 20 percent and drug arrest rates by about 18 percent police bureaucrats apparently desire discretionary budget increases and they have considerable discretion in determining resource allocation

the effects of excise taxes and regulations on cigarette smoking abstract we estimate a generalized linear model to examine adult and teenage cigarette demand our analysis focuses on the extent to which exice taxes and regulations restricting smoking in public places affect cigarette consumption the adult results indicate that the price elasticity of demand is unstable over time ranging from 0 06 in 1970 to 0 23 in 1985 these estimates are lower than most found in previous studies the teenage price elasticity does not differ statistically from the estimates for adults additionally regulations restricting smoking in public places have a significant effect on both adult and teenage cigarette demand

heroin consumption prices and addiction evidence from self reported panel data estimation models of drug demand should encompass the aspect of addiction here we consider two static panel data regression models and two cross section models with lags or leads in drug consumption as additional regressors heroin injectors attending a needle exchange service in oslo were interviewed twice with a one year interval despite our relatively small sample we obtain statistically significant price and income responses for nearly all of the models and specifications applied the sample is split by dealing status with dealers obtaining price elasticities in the range of 0 15 1 51 and non dealers 0 71 1 69 somewhat surprisingly the estimates of the variance of the latent individual specific variable are rather low in the panel data models although higher for non dealers than for dealers

empowering rural people for their own development abstract this elmhirst lecture first discusses the features of the institutional environment which allow rural people in low income countries to design plan and implement their own rural development these are divided into two broad groups the institutional environment for rural development environment for the private sector communities and civil society local government and sector institutions and the many factors governing profitability of investment in agriculture while in many poor countries the institutional environment has improved over the last 20 years the most poorly performing countries still have by far the poorest environment for local government in the world within an empowering institutional environment the rate of agricultural and rural development is determined by investments of many different types that in turn depend primarily on the profitability of agriculture the paper discusses the large number of factors which determine profitability few of these are under the direct control of farmers or agricultural sector institutions but depend on governance and investments in other sectors such as trade and transport in many of the poorest countries there has been considerable improvement in macro economic management and sector policies over the past 20 years but progress in international and intra regional trade policies in agricultural trade policies in transport infrastructure and in agricultural research and extension have been limited

growth options and poverty reduction in ethiopia an economy wide model analysis abstract this study focuses on which agricultural subsectors are important in ethiopia s economic growth and poverty reduction and what kind of agricultural and nonagricultural growth is needed to achieve the millennium development goal of halving the incidence of poverty by 2015 a spatially disaggregated economy wide model was developed enabling the analysis of growth and poverty reduction linkages at national and regional levels using national household surveys agricultural sample surveys geographic information systems and other national and regional data the study reveals that agriculture can play a central role in decreasing poverty and increasing growth in ethiopia within the agriculture growth in cereals and other staple crops should receive priority agricultural growth also requires concurrent investments in roads and other market conditions at the subnational level similar growth rates within agricultural subsectors have different effects on poverty necessitating regionally based strategies for growth and poverty reduction

rural bias in the east and south east asian rice economy indonesia in comparative perspective this study analyses the rise in protection of rice farmers in east and south east asia since 1960 a statistical model of price formation is tested for japan south korea malaysia the philippines and indonesia on average about 90 per cent of variation in rice prices in these five countries relative to the world price can be an attributed to efforts at price stabilisation rather than farmer protection or discrimination in earlier periods the shift from urban bias to rural bias is more a result of price stabilisation and declining real rice prices in world markets than basic shifts in political economy

is property crime caused by drug use or by drug enforcement policy the relationships among drug offenses prorperty crime and the allocation of police resources are investigated in a structural model using data from florida countries law enforcement resources are scarce and as efforts to combat drug crime increase the amount of these resources allocated to property crime is reduced this reallocation of police resources results in reduced deterrence for property crime and as a result an increase in these crimes the evidence presented suggests that rising property crimes in florida are at least partially the result of drug enforcement policy

monitoring and enforcement of environmental regulations lessons from a natural field experiment in norway abstract relying on a small natural field experiment conducted by the norwegian environmental protection agency i estimate effects of three fundamental elements of most monitoring and enforcement practices self reporting audit frequency and specific deterrence i find evidence of under reporting of violations in firms self audits as more violations are detected in on site audits than in self audits announcing the increased audit frequency has no effect on firms compliance but an audit raises subsequent compliance substantially

structure of public support for national agricultural research systems a political economy perspective abstract this paper initiates development of a set of stylized facts concerning the structure of public support for national agricultural research systems nars within a neoclassical political economy framework the aim is to place public funding of nars in the broader context of the overall level of direct government assistance to agriculture using a newly constructed data set on nars expenditures over the 1970 1985 period we observe a growing disparity in agricultural research intensity ratios which measure the level of public support for nars in relation to agricultural gross domestic production aggdp between low and high income countries this growing disparity appears to be driven by much larger increases in support for agricultural research by high income countries coupled with a significantly slower growth in the size of their agricultural sector despite the propensity of low and middle income countries to increase real support to agricultural research as per capita incomes rise the public agricultural expenditure ratio which measures public expenditures on agriculture relative to the size of the agricultural sector aggdp increases substantially public expenditures on agriculture were indexed on agricultural and non agricultural populations to give a rough indication of the increasing incentives for rural distributional coalitions to seek a redistribution of public expenditures in their favor a relative research expenditure rre ratio is developed which measures the proportion of total public expenditure on agriculture spent on agricultural research it provides an indication of the relative importance given to research on agriculture within the constraints imposed by overall public spending on agriculture in contrast to the agricultural research intensity ratios the rre ratios suggest that agricultural research appears to command as large a share of the public purse devoted to agriculture in low and middle income countries as it does in high income countries expectations derived from the neoclassical political economy literature that research may have fared relatively better in high compared with low income countries were not supported by the data

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

are there efficiency gains from the removal of natural resource export restrictions evidence from british columbia log export bans lebs are a popular development tool utilised by developing nations with sizable endowments of timber however the actual impact of these policies is debatable british columbia has a developed forestry sector and still maintains a leb this trade restriction continually creates conflicts with canada s international trade partners including the united states this paper examines the efficiency implications of a hypothetical removal of roundwood export restrictions in british columbia using roundwood price and quantity data from 1995 to 2008 a time series econometric approach is utilised to determine supply and demand elasticities for british columbia s roundwood empirical results from a vector error correction model suggest that a removal of export restrictions will generate an overall increase of approximately 347 91 million us dollars per year to british columbia s forest economy

the demand for cocaine by young adults a rational addiction approach abstract this paper applies the rational addiction model to the demand for cocaine by young adults in the monitoring the future panel the price of cocaine is added to this survey from the drug enforcement administration s system to retrieve information from drug evidence results suggest that annual participation and frequency of use given participation are negatively related to the price of cocaine in addition current participation frequency is positively related to past and future participation frequency the long run price elasticity of total consumption participation multiplied by frequency given participation of 1 35 is substantial

agricultural export subsidies and domestic support reform under the wto system what does it mean for welfare in west africa this paper analyses the potential welfare impacts west africa tends to encounter from liberalising agricultural export subsidies and domestic support in developed and developing countries according to the reform proposals of the doha development agenda we base our analysis on the july framework scenario which considers a tiered formula that adopts a harbinson approach plus sensitive and special product provisions the results indicate that while the world prices of the major exportable commodities of the region will fall those of their imports will rise subsequently consumers of nearly all of the commodities analysed encounter potential welfare losses while almost all producers of these commodities experience potential welfare gains consumers are expected to encounter an aggregate loss of about 591 93 million while a net producer surplus of about 423 78 million is expected to be generated however because the gains by producers are insufficient to compensate consumers losses the fifteen west african nations considered in the analysis are expected to experience a net welfare loss of about 168 16 million on the contrary large developing countries such as brazil india and china as well as developed nations like the eu and japan are expected to enjoy net welfare gains the net losses accrued to the region imply more poverty and heightened food insecurity as all west african countries faced severe hunger situation in 2010 however even though these findings conform to other research results indicating net food importing countries will become losers from agricultural trade reform while net food exporters experience welfare gains concerns of data quality and reliability that are usually associated with macrolevel analysis render these results more indicative than definitive

agricultural policy adjustments in the korean rice economy abstract a political preference function is used to endogenize government actions in a simultaneous equation model for south korean rice policy the effects of economic changes on rice pricing decisions through estimated political weights are tested to improve our understanding of policy adjustments in that country and open the way for further research in east asia

the price elasticity of hard drugs the case of opium in the dutch east indies 1923 1938 at the beginning of this century the dutch government controlled the opium market in the dutch east indies nowadays indonesia for several decades this state monopoly was called the opiumregie using information gathered during the opiumregie this paper estimates price elasticities of opium consumption it appears that short term price elasticities of opium use are about 0 7 long term price elasticities are about 1 0

a comparison of alternative models for the demand for medical care we have tested alternative models of the demand for medical care using experimental data the estimated response of demand to insurance plan is sensitive to the model used we therefore use a split sample analysis and find that a model that more closely approximates distributional assumptions and uses a nonparametric retransformation factor performs better in terms of mean squared forecast error simpler models are inferior either because they are not robust to outliers e g anova anocova or because they are inconsistent when strong distributional assumptions are violated e g a two parameter box cox transformation

the demand for alcohol the differential response to price although several studies indicate that drinking is responsive to price little work has focused on whether prices have a differential effect on light moderate or heavy drinking this study examines the price responsiveness of the demand for alcohol whether heavy drinkers are less sensitive to price than light or moderate drinkers the study uses data on alcohol consumption on the 1983 national health interview survey the results indicate that both light and heavy drinkers are much less price elastic than moderate drinkers further we cannot reject the hypothesis that the very heaviest drinkers have perfectly price inelastic demands

the effect of cocaine prices on crime the relationship between cocaine prices and crime has critical implications for u s drug policy but is theoretically indeterminate because cocaine price changes affect crime through changes in both cocaine consumption and expenditures this paper investigates this relationship in annual data from 1981 95 on 29 large u s cities accounting for simultaneity by using two stage least squares with measures of wholesale supply factors and retail enforcement intensity as instruments for cocaine prices controlling for prices of other drugs deterrence socioeconomic factors and city and year specific effects a strong negative relationship exists between cocaine prices and six of seven fbi index crimes

the diffusion of e commerce among smes theoretical implications and empirical evidence as a specific institution of distributive trades e commerce displays similarities with retail stores and mail order companies as well as providing theoretical support for the assumption that e commerce is a way to sell certain goods and services at prices potentially lower than those of traditional distributive channels this paper analyses its inter firm diffusion among a sample of firms mostly smes in italy the paper has three main purposes firstly it challenges the view of e commerce as a technological revolution by pointing out its nature as a cost minimizing marketing channel in particular it shows how under certain conditions e commerce is a source of transaction cost advantages analogous to those yielded by mail order business secondly the paper identifies from a theoretical viewpoint the circumstances under which e commerce sales might achieve a significant level of penetration among those smes that would otherwise incur high costs in organizing a proprietary distributive channel thirdly it employs a unique data set of italian manufacturing service and hospitality firms nearly 90 of them with fewer than 100 employees to estimate a diffusion model based on the logistic curve according to the estimates by the fourth quarter of 2003 nearly 50 of the population of firms in the geographical area surveyed will have introduced e commerce among their marketing channels

an empirical analysis of milk addiction we show the estimable rational addiction model tends to yield spurious evidence in favor of the rational addiction hypothesis when aggregate data are used direct application of the canonical model yields results seemingly indicative that non addictive commodities such as milk eggs and oranges are rationally addictive monte carlo simulation demonstrates that such results are likely to obtain whenever the commodity under scrutiny exhibits high serial correlation or when even a small amount of the variation in prices is endogenous or when overidentified instrumental variables estimators are used or when commonly imposed restrictions are employed we conclude that time series data will often be insufficient to differentiate rational addiction from serial correlation in the consumption series
