introducing incentives in the market for live and cadaveric organ donations we evaluate the introduction of monetary incentives in the market for live and cadaveric organ donations we show that monetary incentives would increase the supply of organs for transplant sufficiently to eliminate the very large queues in organ markets and the suffering and deaths of many of those waiting without increasing the total cost of transplant surgery by more than about 12 percent we build on the value of life literature and other parts of economic analysis to estimate the equilibrium cost of live transplants for kidneys and livers we also show that market price for kidneys will be determined by the cost of live donations even though most organs will come from cadavers

agricultural price instability a survey of competing explanations and remedies there are two explanations for agricultural price dynamics one follows cobweb logic and models fluctuations driven by expectation errors but emphasises that these expectations create complex dynamics and possibly chaos the other stems from the rational expectations tradition of dynamics driven by real shocks the empirical evidence tends to support the latter but is not conclusive the rational expectations model generates an optimal dynamic path from which no improvement can be expected from public intervention however if we take account of all the potential market failures in agricultural markets and especially in developing countries this conclusion might require some qualifications although an appropriate policy design for stability has still to be achieved this paper surveys the positive and normative literature on agricultural prices highlighting empirical evidence and identifying remaining unresolved issues

ethnicity neighborhoods and human capital externalities the socioeconomic performance of today s workers depends not only on parental skills but also on the average skills of the ethnic group in the parents generation or ethnic capital this paper investigates the link between the ethnic externality and ethnic neighborhoods the evidence indicates that residential segregation and the external effect of ethnicity are linked partly because ethnic capital summarizes the socioeconomic background of the neighborhood where the children were raised ethnicity has an external effect even among persons who grow up in the same neighborhood when children are exposed frequently to persons who share the same ethnic background copyright 1995 by american economic association

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

how far down the path to free trade the importance of rice price stabilization in developing asia abstract international trade agreements are pushing the world in the direction of free trade but price stabilization which is inconsistent with completely free trade remains important in developing asia because of the large share of rice in economic output a policy of pure price stabilization for rice without consistent protection either subsidization or taxation can help to create the macroeconomic stability that is essential for sustained rapid economic growth by increasing the quantity and efficiency of investment throughout the economy pure price stabilization can also generate significant equity gains by protecting poor consumers and farmers from sharp fluctuations in prices while domestic commodity price stabilization schemes have a checkered history around the world the experience of asian countries in stabilizing rice prices offers more scope for optimism asian governments have been generally successful in stabilizing rice prices and there are several instances where this has been accomplished without sustained protection of either consumers or farmers however there is room for improved stabilization mechanisms that would lower the costs of intervention

markets and morality it is common knowledge that adam smith the acknowledged father of economics as we know it had written the theory of moral sentiments 1759 before he wrote the wealth of nations 1776 more sophisticated students of economics today would also know that adam smith held the chair in moral philosophy from 1752 after a year as professor of logic at glasgow university therefore that economics has evolved from moral philosophy and has affinity by birth with it and therefore is a moral science should not surprise anyone yet the analysis of the interaction between economics and moral philosophy or perhaps simply morality has raised interesting issues over time in the following i concentrate on a few salient ones today

wheat storage and trade in an efficient global market domestic and international linkages in speculative stockholdings and trade of wheat are analyzed using a dynamic rational expectations model of the world wheat market dominated by the u s and the eu the results demonstrate the importance of endogenizing both storage and trade in studying commodity markets and suggest that past government stockholdings have not followed efficient market outcomes results indicate that elimination of the export enhancement program by the u s and of export restitution payments by the eu are unlikely to have a major impact on wheat exports from the two regions but will save millions of tax dollars in both regions

labor migration and earnings differences the case of rural china this article presents empirical evidence supporting the hypothesis that the decision of chinese rural people to migrate is affected by noneconomic forces using the 1820 rural household survey from sichuan province migration behavior and earnings are analyzed logistic probability models show that the decision to migrate is driven largely by the availability of rural non farm employment opportunities however if jobs are available in the province even at lower wages rural people will choose to stay rather than to migrate the major deterrent to migration is the lack of safety during transportation and in destination cities as well as forced separation from families moreover rural migrants are denied the legal right to reside permanently in cities furthermore findings reveal that although labor productivity in migrant activities is higher than it is in local non farm sectors the economic cost of migration in china is so high as to significantly limit reallocation one implication of this study is that without artificial barriers to labor migration the number of migratory workers would be higher since the important objective of the chinese government is to control rural to urban migration it is likely that restrictive migration policies will continue however putting aside the issue of social justice the economic efficiency loss under the chinese system should not be ignored

liberalized trade and domestic price stability the case of rice and wheat in india abstract this paper analyzes the effects of liberalizing foodgrain trade on domestic price stability using a multi market equilibrium model in which the direction of trade is determined endogenously and world prices are sensitive to the amount traded by india simulation results demonstrate that contrary to popular belief freeing of trade by india leads to greater domestic price stability even though world prices are more volatile freeing of trade by india also leads to higher world price stability under liberalized trade variable levies subsidies are more effective in stabilizing domestic prices compared to buffer stocks it is therefore in india s interest to argue for non zero binding on import tariffs and export subsidies at the wto negotiations

subsidy or market reform rethinking china s farm consolidation strategy chinese food security policy is anchored increasingly on the conviction that domestic grain production should be greatly enhanced and the best way to do so is to expand farm production scale to that end an increasing stream of public investment has been directed to the grain sector in the form for example of farm expansion subsidies our purpose is to assess the potential impacts of china s farm scale expansion on both yields and per hectare economic returns analysis of a large sample of farm household production data finds with some exceptions that grain yields likely will decline as farm size grows compromising food self sufficiency targets more importantly in only isolated cases would per hectare economic returns decline with size thus an emphasis on reducing farmland transactions costs may stimulate cropland consolidation and achieve the desired long term structural transformation

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

the subsidization of farming households in china s agriculture concerned about national food self sufficiency and rural household incomes in 2004 china decided to reverse its longstanding policy of taxing farm households and instead began to provide them with subsidies since 2004 annual announcements have trumpeted rises in subsidies despite the historic turnaround of policy and likely implication of this subsidy policy to china s food economy there has been little household level survey based research that has sought to understand the nature of china s subsidy programs from the viewpoint of the farmer using data from two sets of household based surveys covering tens of thousands of households and most major producing provinces and survey data from government in this paper we examine the subsidies that are directly given to farmers one of the newest and relatively high profiles components of china s subsidy programs we focus on china s grain input seed and machinery subsidy programs according to the survey based findings we show that although agricultural subsidies per farm are low on a per hectare basis the rate of subsidies is high almost all producers are receiving them subsidies are mostly being given to the land contractor not the tiller most of grain input and seed subsidies are non distorting but machinery subsidy is based on farmers actual purchase of machineries

impact of food inflation on poverty in the philippines abstract we simulate the impact of food inflation between june 2006 and june 2008 on poverty across different areas and between agricultural and non agricultural households we explicitly treat the spatial heterogeneity in food inflation and the differences in consumption and production patterns across households by merging household expenditure survey and price datasets at the provincial level or lower although some of the poor agricultural households may have escaped poverty the poorest of the poor whether they are in an agricultural household or not are severely and adversely affected by the food inflation

grain price stabilization experiences in asia what have we learned abstract governments in most asian countries used grain price stabilization as a major policy instrument when they embarked on promoting the green revolution the art of public policy making is to know when to introduce government interventions and when to withdraw the common mistake is to forget the withdrawal part leading to unsustainably high costs a dilemma that most asian countries are confronted with today analyzing case studies of six asian countries which have tried to tackle the task in different ways with varying degrees of success eight key lessons can be learned from the more than three decades of food price stabilization in asia times have changed policies and public agencies that may have been appropriate 30 years ago are not optimal today private institutions have strengthened significantly or could be strengthened significantly and should be entrusted for many of the functions that parastatals or other government agencies have traditionally performed holding on to old practices delays reaping the benefits that changing current policies have to offer

emporiophobia fear of markets cooperation or competition there is widespread emporiophobia fear of markets and this has important policy implications as it leads voters to demand anti market policies there are many reasons for this anti market attitude however economists could reduce emporiophobia if we stressed cooperation rather than competition in our writings and policy discussions in a sample of introductory textbooks competition is mentioned on average 8 times as often as cooperation the fundamental economic unit is the transaction and transactions are cooperative the benefit of a market economy increased consumer surplus comes from cooperation through transactions not from competition competition in a market economy is competition for the right to cooperate competition is important because it guarantees that the best cooperators will win and because it establishes the efficient terms for cooperation but cooperation is fundamental for most people competition has negative connotations as it focuses on losers while cooperation implies a winwin situation as an example if we say wal mart outcompeted its rivals we think of losing firms being bankrupted if we say wal mart did a better job of cooperating with its customers we think of the benefits created by wal mart economists in our policy and textbook writing should strive to use the second sort of locution not the first other implications involve the morality of the market giving back and characteristics of market failures

price stabilization using buffer stocks abstract the price stabilization problem is stated and solved for a nonlinear cobweb model with government stocks it is shown that if the storage capacity for the commodity is sufficiently large then there exists a simple stabilization policy called the keep supply at equilibrium kse policy such that the equilibrium price is a global attractor for the corresponding closed loop system in addition it is shown that if the government approximates the equilibrium supply with the average supply stabilization is guaranteed we refer to this policy as keep supply at average ksa

price stabilization and impacts of trade liberalization in the southeast asian rice market abstract a global rice model using a partial equilibrium framework is used to investigate the impact of trade liberalization in major rice trading countries of southeast asia focusing on the price stabilization mechanism that has long been adopted by governments in indonesia malaysia and the philippines the simulation results suggest that the removal of state trading enterprises in these three countries would lower their domestic prices by as much as 34 but increase the world prices by about 20 when free trade liberalization is realized in 2020 domestic prices decline further in indonesia and the philippines leading to an increase in their imports which are estimated to be as much as 4 5 million tons the impact on domestic prices however is absorbed nearly evenly among indonesia the philippines thailand and vietnam

food security and storage in the middle east and north africa in times of highly volatile commodity markets governments often try to protect their populations from rapidly rising food prices which can be particularly harsh for the poor a potential solution for food deficit countries is to hold strategic reserves which can be called on when international prices spike but how large should strategic stockpiles be this paper develops a dynamic storage model for wheat in the middle east and north africa mena region where imported wheat dominates the average diet the paper uses the model to analyze a strategy that sets aside wheat stockpiles which can be used when needed to keep domestic prices below a targeted price this paper shows that if the target is set high and reserves are adequate the strategy can be effective and robust contrary to most interventions strategic storage policies are counter cyclical and when the importing region is sufficiently large a regional policy can smooth global prices this paper shows that this is the case for the mena region nevertheless the policy is more costly than the pro cyclical policy of a targeted intervention that directly offsets high prices with a subsidy similar to food stamps

a political economic analysis of u s rice export programs to japan and south korea a game theoretic approach the uruguay round agreement on agriculture ur has contributed to the increase in u s and world rice trade since 1994 despite this the japanese and korean rice markets continue to be characterized by high levels of trade intervention this paper attempts to analyze both import markets incorporating econometric estimates and public choice theory in a game theoretic framework various scenarios are analyzed the results show that the overall nash equilibrium occurs with a 4 tariff reduction for japan and korea under the u s market development program which includes the market access program and foreign market development program

food price policy the rationale for government intervention abstract policy makers in the most successful developing countries have not accepted either of the two major schools of thought on food price policy the neo classical school favours free trade to maximize efficiency of resource allocation the structuralist school favours interventions to satisfy goals for income distribution especially in the rapidly growing rice based economies of asia policy makers have been more concerned about stability of domestic prices than their level relative to world prices this concern traditionally dismissed by economists as purely political is justified on economic grounds because of improved macroeconomic and dynamic efficiency from stable food prices the paper identifies both the benefits from food price stability and the costs of achieving it

optimal food price stabilization in a small open developing country in poor countries most governments implement policies aiming to stabilize the prices of staple foods which often include storage and trade measures insulating their domestic market from the world market it is of crucial importance to understand the precise motivations and efficiency of those interventions because they can have consequences worldwide this paper addresses those issues by analyzing the case of a small open developing country confronted by shocks to both the crop yield and foreign price in this model government interventions may be justified by the lack of an insurance market for food prices considering this market imperfection the authors design optimal public interventions through trade and storage policies they show that an optimal trade policy largely consists of subsidizing imports and taxing exports which benefits consumers at the expense of producers import subsidies alleviate the non negativity of food storage in other words when stocks are exhausted subsidizing imports prevents domestic price spikes one striking result an optimal storage policy on its own is detrimental to consumers since its stabilizing benefits leak into the world market and it raises the average domestic price by contrast an optimal combination of storage and trade policies results in a powerful stabilizing effect for domestic food prices

domestic and international impacts of the rice trade policy reform in the philippines abstract faced with high domestic rice prices that have fueled inflation above the 2018 target and penalized poor consumers the most the government of the philippines has decided to abandon the quantitative restrictions on imports and replace them with tariffs this paper uses a global rice model based on a partial equilibrium framework to assess the possible impacts of this reform on imports production consumption and prices in contrast with past similar studies we address three key concerns i the heterogeneity in farm price across 16 regions in response to the combined effect of the tarriffication and the average historical trend in productivity increase at 1 5 between 2001 and 2018 ii the differentiation of imports by origin partly due to the different tariffs applied to countries within and beyond the association of south east asian nations and iii the effect on domestic prices in third countries the simulation results suggest that the reform would increase imports by 2 47 million tons 20 7 in 2019 we also find a large decline in farm prices and retail prices respectively by php 6 1 kg 30 1 and php 7 6 kg 17 4 in 2019 that explains an increase in rice consumption we estimate the fall in total inflation at 1 2 in 2019 but less over time further the large fall in farm prices in 2019 is shared quite evenly among regions in the short term but returns to pre reform levels in the near term using a higher price elasticity of supply for one region obtained from panel data surveys we show a more pronounced decline in production than the national average such differentiated results confirm the relevance of using a regionally disaggregated model to design more targeted policies we also show a slight increase in world prices which led to small increases in the domestic prices of south and southeast asian rice markets while this reform is largely pro poor consumers policy makers would need to use the additional tariff revenue to help rice growers either increase their competitiveness and modernize their rice production or shift to other crops

ethnic capital and intergenerational transmission of educational attainment this paper studies the role of ethnicity in the intergenerational transmission of educational attainment within the framework outlined by borjas quarterly journal of economics 1992 107 1 123 150 relying on heteroskedasticity to identify parameters in the presence of endogenous regressors i find evidence that the ordinary least squares estimates of the effect of ethnic capital on intergenerational transmission of education are biased upwards due to the transfer of unobserved ability i also find that while the role of parental capital has declined over time ethnic capital has a relatively constant effect on intergenerational transmission of educational attainment

wto negotiations on agriculture and the distributional impacts for us rice farm households abstract the policies of wealthy countries have proven the most difficult to reform in the wto doha round negotiations considerable emphasis has been placed on developing country impacts but a gap in the literature remains on the stakes for rich country farmers despite the large role these countries play in global agricultural protection the research here considers the particular case of us rice households and their sensitivity to japanese market access reform using an applied general equilibrium model with multiple farm households we highlight the distributional impacts among these producers we argue that concessions to japan on market access make domestic reforms in rice a difficult political sale in the us since the wealthiest producers bear the largest losses improving our understanding of the distributional impacts and political realities of the richest countries is critical to informing the negotiating process because the gains to the world s poor can only be realized with creative policy redress in these rich nations

trade liberalization and domestic price instability in an agricultural commodity market price instability appears to be a feature of many agricultural markets in turn reduction of instability is a key motive for intervention in industrialized countries where trade instruments are used for this purpose they can sever the link between domestic and international prices the consequences of market insulation for price variability are examined a simple partial equilibrium model is developed and its predictions are examined against the experience of liberalization in the british main crop potato market

public investment and regional inequality in rural china this paper develops a method for decomposing the contributions of various types of public investment to regional inequality and applies the method to rural china public investments are found to have contributed to production growth in both the agricultural and rural non agricultural sectors but their contributions to regional inequality have differed by type of investment and the region in which they are made all types of investment in the least developed western region reduce regional inequality whereas additional investments in the coastal and central regions worsen regional inequality investments in rural education and agricultural r d in the western region have the largest and most favorable impacts on reducing regional inequality

does agricultural trade liberalization increase risks of supply side uncertainty effects of productivity shocks and export restrictions on welfare and food supply in japan abstract agriculture is the focus of much contention in free trade negotiations the japanese government is against liberalizing the rice trade on the grounds that it would threaten national food security in the events of such shocks as crop failure and embargoes trade liberalization is expected to make the japanese economy more dependent upon food imports and thus more susceptible to these risks using a computable general equilibrium model with a monte carlo simulation we quantify the welfare impacts of productivity shocks and export quotas by major rice exporters to japan and found little evidence of japan suffering from such shocks

self selection and the earnings of immigrants this paper analyzes the way in which the earnings of the immigrant population may be expected to differ from the earnings of the native population because of the endogeneity of the decision to migrate the empirical study shows that differences in the u s earnings of immigrants with the same measured skills but from different home countries are attributable to variations in political and economic conditions in the countries of origin at the time of migration excerpt

impacts of liberalizing trade in the world rice market a multi product quadratic programming model is used to investigate impacts of trade liberalization on the world rice market recognizing product differentiation and allowing substitution among various rice types and qualities model simulations predict a large increase in both trade volumes and prices for all rice types and a significant welfare gain for most rice exporters and importers japan south korea philippines taiwan and brazil would be the major importers trade liberalization would increase total u s export revenue by 109 movement to free trade by japan has significant effects on world rice trade and on japanese rice production

impact of rice tariffication on japan and the world rice market the uruguay round agreement of the world trade organization wto and other trade agreements such as nafta and mercosur have contributed to the increase in u s and world rice trade since 1994 rice however continues to be one of the most highly protected agricultural commodities with current tariff rates in several developing countries ranging from 50 to 230 protectionist policies for rice include tariffs tariff rate quotas state trading and various domestic government programs amponsah colyer and jolly before implementation of the uruguay round agreement japan and south korea maintained an almost complete ban on rice imports to begin opening these markets the uruguay round provided special minimum market access ma rules with the goal of eventually shifting to tariffication the grace period for tariffication was set at six years for japan 1995 to 2000 and ten years for south korea 1995 to 2004 south korea received additional time for tariffication and a lower

export liberalization and household welfare the case of rice in vietnam vietnam has rapidly become one of the three largest rice exporters in the world in spite of a binding export quota this article uses a multimarket spatial equilibrium model to examine the effect of further liberalization on regional rice prices household data are then used to calculate the welfare impact of these price changes on different household groups the results suggest that although rice export liberalization would raise food prices and exacerbate regional inequality it would also increase average real income and reduce slightly the incidence and severity of poverty we explore several explanations of these apparently paradoxical results

tariff rate quotas structural and stability impacts in growing markets abstract this paper examines several aspects of tariff rate quotas trq as adopted during tariffication of agricultural policies under the uruguay round of gatt quota rents and non tariff barrier effects may remain under trqs contrary to the objectives of the tariffication process further price stability impacts of a trq are more complex than those for either tariffs or quotas and under certain circumstances trqs may be more stabilizing than either case since trqs truncate domestic production distributions much like price bands policies this complexity results from the possibility of regime switching and may reflect behavior under either a tariff a quota or a combination of cases a trq policy may affect the timing of import decisions based on incentives created under quota allocation procedures envisioned for this institution it may also allow increased imports as demand growth occurs because the quota is not necessarily a binding constraint this means the above quota tariff is the critical policy instrument an empirical study of philippines pork imports illustrates these issues

long term crop productivity response and its interaction with cereal markets and energy prices abstract crop yields are endogenous as long as economic agents adjust to permanent changes in expected prices the literature however does not offer a definitive value of how much yield would change in response to sustained price changes to fill the gap we use available scientific findings and data to estimate yield elasticities that enable agricultural commodity and food policy analysis using a world market model with short to long run yield response we show the impacts of sustained energy price shocks on global cereal supply and demand the results highlight substantial differences in quantity and price effects depending on the yield elasticities these results demonstrate the need to recognize yield response when assessing impacts of energy prices or biofuel production on food uses or more generally on food security in the face of income and population growth evolving dietary patterns climate change implications or other long run pressures

export restrictions and price insulation during commodity price booms for individual countries variable trade barriers can be used to reduce the volatility of domestic relative to world prices if this is done by countries accounting for a large share of the market its effect is offset by increases in world price volatility this study shows the nature of the resulting collective action problem with the policy being ineffective on average in stabilizing domestic prices while increasing the volatility of the income transfers from terms of trade changes a simple approach to assessing the contribution of insulation to the price increases is developed and used with new estimates of agricultural distortions to assess its contribution to the price spikes in 1972 74 and 2006 08 for rice and wheat the analysis suggests that 45 percent of the increase in rice prices in 2006 08 and 30 percent of the increase in wheat prices was due to insulating behavior one sign of progress since 1972 74 was a substantial reduction in the extent of price insulating behavior by the industrial countries this provides little stabilizing benefit in the rice market because countries not classifying themselves at the world trade organization as developing account for only 3 percent of world rice consumption but it does offer some benefit for the wheat market where non developing countries account for 27 percent of consumption

the impacts of india s food security policies on south asian wheat and rice markets we quantify the extent to which india s success in stabilizing its wheat and rice markets affects other countries in south asia we deal with the variability of indian trade and price policies by a

is free trade passe abstract if there were an economist s creed it would surely contain the affirmations i understand the principle of comparative advantage and i advocate free trade yet the case for free trade is currently more in doubt than at any time since the 1817 publication of ricardo s principles of political economy and this is due to changes that have recently taken place in the theory of international trade while new developments in international trade theory may not yet be familiar to the profession at large they have been substantial and radical in the last ten years the traditional constant returns perfect competition models of international trade have been supplemented and to some extent supplanted by a new breed of models that emphasizes increasing returns and imperfect competition these new models call into doubt the extent to which actual trade can be explained by comparative advantage they also open the possibility that government intervention in trade via import restrictions export subsidies

trade liberalization and national food security rice trade between bangladesh and india abstract following a poor harvest in late 1997 and a massive flood in 1998 private sector traders in bangladesh imported several million metric tons of rice from india this paper presents evidence that this trade made possible by separate trade liberalizations in india and bangladesh in the early 1990s augmented domestic supplies and stabilized prices in bangladesh at import parity levels letters of credit data indicating the participation of hundreds of importers and a close correlation of price movements across the two countries suggest that the trade was competitive a risk of co incident crop shortfalls in the two countries remains though these have occurred rarely in the past two decades bangladesh imports from alternative sources would also enhance food availability if another production shortfall occurs but these imports face higher transport costs and would involve far fewer importing firms given the economies of scale of shipments by sea the positive contribution of trade liberalization to short run food security in bangladesh in recent years does not minimize the importance of increased agricultural productivity and rural economic growth to provide rural poor households with sufficient incomes to acquire food nonetheless the bangladesh experience shows that trade liberalization offers potential benefits for national food security by enabling a rapid increase of food supplies following domestic production shortfalls

trading off volatility and distortions food policy during price spikes this paper analyses the trade off between price distortions and reduced volatility when governments intervened in agricultural and food markets during the recent food price spikes we develop a model to derive how much distortions a government would introduce when it cares about price stability in a situation with limited policy options we show that there is a trade off and identify the optimal combination of distortions and stability for given international price shocks and interest groups preferences for stability we compare these theoretical findings with empirical indicators on actual government interventions in staple food markets we find that several countries have been able to reduce short run price volatility in the domestic markets while at the same time allowing structural medium and long term price changes to pass through to producers and consumers however this is not the general case for many countries even when explicitly taking into account the trade off and the benefits of reducing volatility government policies appear far removed from the optimal trade off and there appears to be much room for policy improvement

growth growth accelerations and the poor lessons from indonesia we study the impact of growth and growth accelerations on poverty and inequality in indonesia using a new panel dataset covering 26 provinces over the period 1977 132010 this dataset allows us to distinguish between mining and non mining in indonesia growth in non mining significantly reduces poverty and inequality in contrast overall growth and growth in mining appears to have no effect on the same growth acceleration in non mining reduces poverty and inequality whereas the same in mining increases poverty we expect that the degree of forward and backward linkages of mining and non mining sectors explains the asymmetric result

policy coherence and food security the effects of oecd countries agricultural policies there have been important changes to agricultural policies in many oecd countries over the past decade and the international spill over effects of support and protection have diminished now would be a good time to eliminate remaining distortions and put in place more efficient alternatives including social safety nets and tools to help farmers manage risk this would lock in the benefits of reform and simultaneously address charges of policy incoherence in the context of high food prices new issues have emerged with potential implications for food security they include export restrictions the use of biofuel mandates and the opportunities and threats presented by increased foreign investment in agriculture on these issues as well as in terms of conventional support mechanisms policies in emerging economies in particular the briics are increasingly important a pro active agenda for policy coherence would involve not just eliminating policies that distort trade but also enacting positive measures to increase food availability for example by raising agricultural productivity using resources sustainably and eliminating waste and over consumption across countries there are important gains to be realised from knowledge sharing and from multilateral action to provide global public goods not least smoother functioning of the multilateral trading system
