does household composition matter the impact of the grain for green program on rural livelihoods in china article i nfo this research introduces family composition into the sustainable livelihoods framework for policy analysis we apply this approach to a case study on the grain for green program in western china using recent survey data from zhouzhi county we show that the impact of the policy on rural livelihoods varies across household compositions the environmental program neither targets asset poor households nor does it necessarily shift the on farm labor to non farm sectors which would improve household incomes after controlling for the effect of assets households with children but without the elderly tend to have lower migration rates and lower incomes after participation in the program policy strategies should consider household heterogeneity particularly household composition in rural china

tenure land rights and farmer investment incentives in china the goal of this paper is to understand the nature of the property rights associated with china s land tenure systems and to study the impact of these property rights on agricultural production efficiency the results show that land tenure and associated property rights in rural china affect the production behavior of farmers the most robust finding is that the right to use land for long periods of time encourages the use of land saving investments while the results show that land tenure affects agricultural production decisions the difference between collective and private plots however is small compared to the private plotcommunal productivity gap that existed in the pre reform period 1998 elsevier science b v all rights reserved

investment and financing activity following calls of convertible bonds abstract the staged financing hypothesis of mayers mayers d 1998 why firms issue convertible bonds the matching of financial and real investment options journal of financial economics 47 83 102 predicts that investment and financing activity will increase following in the money convertible bond calls the prediction for out of the money convertible calls is different no increase is expected we study the rate of both corporate investment and external financing around forced conversions using benchmarks that are analogous to those recommended by barber and lyon barber b lyon j 1996 detecting abnormal operating performance the empirical power and specification of test statistics journal of financial economics 41 359 400 we also examine the cross section of changes in investment and financing activity conversion forcing firms exhibit an increase in both capital expenditures and debt financing around the year of the convertible bond call however the same result holds for the sample firms that conducted out of the money convertible calls further there is no relation between changes in investment activity and changes in debt issuance at the firm level the evidence is inconsistent with the notion that forced conversions serve as a catalyst for staged financing and investment

tracking distortions in agriculture china and its accession to the world trade organization this article examines the impacts of china s accession to the world trade organization wto on prices in its agricultural sector the analysis uses a new methodology to estimate nominal protection rates in china s agricultural sector before its accession to the wto these new measures account for differences in commodity quality within china and between china and world markets the analysis shows that some of china s agricultural commodities are well above world market prices and others are well below the article also assesses market integration and efficiency in china it finds high degrees of integration between coastal and inland markets and between regional and village markets the remarkable improvements in market performance in recent years mean that if increased imports or exports affect china s domestic price near the border producers throughout most of china will feel the price shifts

the effect of the sloping land conversion programme on farm household productivity in rural china abstractthe objective of this paper is to examine the treatment effect on farm household productivity induced by the sloping land conversion program using large balanced household level data from five provinces during 1996 2010 this study shows that the slcp significantly improved the productivity of participants during the first round of funding of the programme until 2008 while the effects decreased gradually in the second round with most years not showing significant differences moreover it is found that there are heterogeneous effects on farm household productivity between the south and north as well as between poor and rich regions

land tenure arrangements and rural urban migration in china summary obstacles to internal migration in china contribute to inefficiency inequality and land degradation academic and policy debate has primarily focused on discrimination against rural migrants on arrival in urban areas meanwhile barriers to migration out of rural areas have received less attention this paper examines the role of incomplete rural property rights in the migration decisions of rural households we examine the relationship between tenure insecurity and restrictions on land rentals and participation in outside labor markets the results indicate that tenure insecurity reduces migration this relationship is particularly pronounced on forest land which has implications for the conservation of recently replanted forest areas

property rights regimes and natural resources a conceptual analysis revisited summary more than two decades ago schlager and ostrom 1992 developed a conceptual schema for arraying property rights regimes that distinguishes among diverse bundles of rights the conceptual framework has profoundly influenced research on natural resource governance common property and community resource management however currently natural resource governance has changed dramatically challenging the applicability of the conceptual schema there are now many more social actors involved in resource management than the local communities at the focus of original analysis additionally resource management increasingly provides access to various kinds of benefits from outside the immediate context including indirect benefits such as payments for environmental services and results based payments for redd these changes demand addition of new property rights to the original framework this paper updates the conceptual schema in reaction to changes in natural resource governance proposing three specific modifications on the focus of use rights control rights and authoritative rights to come up with a framework that distinguishes eight types of property rights we apply the framework to three purposefully selected governance interventions in china and laos that include the provision of indirect benefits in addition to the direct benefits derived by local people from natural resources the empirical application shows how contemporary governance changes may not lead to local people s outright dispossession since they continue to possess direct use rights to natural resources however local people may be excluded from control and authoritative rights which are exercised exclusively by state agencies and international actors the latter make available indirect benefits to local people which may or may not translate into use rights in the sense of policy based entitlements the empirical insights suggest the possibility of a wider trend of compensated exclusions in natural resource governance

forest loss monetary compensation and delayed re planting the effects of unpredictable land tenure in china abstract over the past 65 years forest tenure in china has oscillated unpredictably between private and village property regimes this policy induced uncertainty has distorted the harvesting decisions of individuals granted rights to grow trees and has lowered the value of china s forest output we provide an analytical framework for assessing these effects quantitatively understanding the consequences of this policy induced uncertainty is particularly important since china is currently engaged in an ambitious plan to increase its domestic supply of timber to conduct this analysis we extend the literature on forestry economics when there is a risk of loss due to forest fire or pests we 1 take account of the possibility that replanting can only resume after an interval of uncertain length with immediate replanting as a special case 2 investigate the effects of compensation for such losses based only on the net value of the stand of trees at the time of the loss and 3 compare it to compensation that would leave the wealth and rotation decisions of the farmer unaffected by the presence of uncertainty

china s sloping land conversion program does expansion equal success this paper uses a 2003 household survey to examine implementation and impacts of china s sloping land conversion program we find that land targeting has been strongly influenced by program goals but that mistargeting also occurred using a treatment effects approach to evaluate program impact we find evidence of positive impact on cropping husbandry and total income though the results are not robust enough to support government claims of huge gains we also find evidence that lack of participant choice could be dampening program impacts and that allowing households autonomy could lead to improvement in program cost effectiveness and outcomes

impacts of climate change on self sufficiency of rice in china a cge model based evidence with alternative regional feedback mechanisms abstract climate change would pose a direct and severe challenge to china s rice production and self sufficiency here we use global trade analysis project gtap model to evaluate the impacts of climate change on the self sufficiency of rice in china due to 2 c rise in temperature and further analyze the impact and transmission mechanisms of climate change through market and trade our simulation method switches different regional mechanisms in the gtap model by employing alternative closures and scenarios our results suggest that the fluctuation in rice price is much larger than that of rice production the active regional feedback mechanism has much larger effects than the passive one in assessing climate change impacts with the passive regional feedback mechanism single regional general equilibrium srge and multi regional general equilibrium with china s shock mrge c china s rice export would decrease by more than 8 and import would increase by over 5 which leads to a decrease in rice self sufficiency by more than 0 06 percentage points with the active regional feedback mechanism multi regional general equilibrium with global shock mrge w climate change will increase china s rice export by 2 7 as rising rice exports to south korea overweight the export decrease to other countries concurrently china s rice import would decrease by 0 04 which leads to a slight increase in rice self sufficiency as a whole climate change will not severely threaten china s rice self sufficiency by the decomposition analysis climate change impacts on china s rice self sufficiency mainly depend on the changes in china s domestic rice production interestingly the source of china s rice import will switch from vietnam to pakistan under mrge w which derives from the input structure of paddy rice and rice sectors in different countries

grain versus food a hidden issue in china s food policy debate abstract the paper examines the likely pattern of china s food trade in the future should china s food trade policy be adjusted to accommodate its comparative advantage differing from the common perception that china s overall food sector will follow the path of grain trade and face an ever growing trend of net imports this study has found an evolving pattern of exchanging food for food in china over the last 15 years the pattern is in part characterized by strong export expansion of selected food products such as vegetables and fruits aquatic products etc the economic rationale behind the pattern is examined through a comparison of relative costs among alternative food products in china the policy implications of the study are discussed

households decisions to participate in china s sloping land conversion program and reallocate their labour times is there endogeneity bias abstract past impact evaluations of china s largest ecological restoration program have assumed the absence of self selection endogeneity in the likelihood and extent of participation using appropriate testing procedures and a panel dataset of 1000 households over 11 years in two primary provinces we found evidence of self selection in household behavior of generating off farm income but the hypothesis was rejected that there was a significant self selection component in households decision to participate in the program and generate farming income evaluations ignoring the self section for off farm labor were found to be biased and overly positive on program income impact self selection should thus be explicitly included unless there is counter evidence in any study of this kind

local versus global separability in agricultural household models the factor price equalization effect of land transfer rights commonly employed global tests for separability between production and consumption decisions are theoretically inappropriate when the market failures creating non separabilities differentially constrain some but not all households simulated maximum likelihood estimates using chinese panel data reject the restrictions implied by a global separability test in favor of regime specific or local separability tests the estimates also show that a global approach to separability obscures the significant effect that less encumbered land transfer rights would have on shadow factor price equalization across households and allocative efficiency the findings on transfer rights suggest a resolution to the debate in china on further property rights reform copyright 2002 oxford university press

designing payments for environmental services in theory and practice an overview of the issues abstract payments for environmental services pes have attracted increasing interest as a mechanism to translate external non market values of the environment into real financial incentives for local actors to provide environmental services es in this introductory paper we set the stage for the rest of this special issue of ecological economics by reviewing the main issues arising in pes design and implementation and discussing these in the light of environmental economics we start with a discussion of pes definition and scope we proceed to review some of the principal dimensions and design characteristics of pes programs and then analyze how pes compares to alternative policy instruments finally we examine in detail two important aspects of pes programs their effectiveness and their distributional implications pes is not a silver bullet that can be used to address any environmental problem but a tool tailored to address a specific set of problems those in which ecosystems are mismanaged because many of their benefits are externalities from the perspective of ecosystem managers pes is based on the beneficiary pays rather than the polluter pays principle and as such is attractive in settings where es providers are poor marginalized landholders or powerful groups of actors an important distinction within pes is between user financed pes in which the buyers are the users of the es and government financed pes in which the buyers are others typically the government acting on behalf of es users in practice pes programs differ in the type and scale of es demand the payment source the type of activity paid for the performance measure used as well as the payment mode and amount the effectiveness and efficiency of pes depends crucially on program design

some neglected social costs of government spending in farm programs economic welfare analyses of farm programs typically assume that the direct social opportunity cost of subsidy payments is one dollar per dollar of government spending recent literature suggests that the marginal opportunity cost of a dollar of u s federal government spending is more likely to be in the range of 1 20 to 1 50 this implies that the net social costs of farm programs that involve government spending are significantly greater than the typical estimates in addition the normative efficiency ranking of alternative policies is sensitive to the marginal opportunity cost of government spending

changes in trade and domestic distortions affecting china s agriculture this paper assesses the implications of china s trade and domestic policies for incentives to producers in china it uses a price comparison methodology nominal rates of assistance at the border and the farmgate with adjustments for exchange rate distortions in the first part of the sample period 1981 1994 on average distortions to agricultural incentives have been reduced in the early 1980s on average china s domestic prices were far below international prices there were substantial variations however between imported which were being protected and exported goods during the 1980s and 1990s the gap between domestic and international prices for both imports and exports narrowed initially mainly due to the elimination of domestic policy distortions between the mid 1990s and 2004 trade liberalization policy furthered narrowed the gap between world and china farmgate prices by the mid 2000s china s agriculture was operating with only small price distortions

dimensions and diversity of property rights in rural china dilemmas on the road to further reform abstract this paper contributes to the debate over land tenure in rural china by conceptualizing and measuring multiple dimensions of property rights in a way that elucidates the competing interests that are affected by the property rights regime utilizing a unique village level data set this paper argues that the regional and temporal variation in rural property rights signals a pattern in which decentralized institutional innovation occurs in response to the competing interests of the national state of local authorities and of present and possible future individual land users unlike the earlier debate concerning the household responsibility system the current property rights dilemma is intrinsically more complex because the potential conflicts of interest between individuals local collectives and the state are greater resolution of that debate will ultimately require careful exploration of the reality and substance of the tradeoffs and competing interests that make further reform of rural property rights so difficult

a theory of monetary exchange the transactions cost for alternative exchange mechanisms for the household exchange problem can be characterized by the computational complexity of the exchange process the computational complexity for any exchange mechanism is at least nh where n is the number of goods and h is the number of households imposing the conditions of conservation nonnegativity and quid pro quo results in a command exchange mechanism whose computational complexity is nh multiparty barter exchange formalized using graph theory has computational complexity

how big is the crowding out effect of user fees in the rural areas of ethiopia implications for equity and resources mobilization summary using a nested multinomial logit model this study investigates the demand reduction and diversion effects of user fees in rural areas of ethiopia the results reveal that an increase in user fees of public clinics which are the most widely used alternative can have a significant demand reduction effect on the poorest of the poor this implies that despite cost recovery has been advocated as an alternative means of health care financing in most of the developing world increasing user fees may drive the poorest segment of the population out of the health care market unless some protective measures are taken

economic factors in farmer adoption of agroforestry patterns observed in western kenya abstract a study of agroforestry adoption by 3 000 project participants in siaya and south nyanza districts in kenya supports three hypotheses 1 1 historical increases in tree domestication and management intensity are responses to declining supply of uncultivated tree resources increased subsistence and commercial demand for tree products and perceived risks of ecological degradation adoption of agroforestry is most likely where consistent with economic incentives for land use change 2 2 high variability in individual farmers tree growing strategies reflects differences in resources and livelihood strategies and household level returns to agroforestry relative to alternative options for meeting specific objectives 3 3 farmers reduce risks associated with new agroforestry practices through incremental adoption and adaptation and cost and risk reducing modifications in technology design

china s sloping land conversion program institutional innovation or business as usual abstract china s sloping land conversion program slcp is the largest land retirement reforestation program in the developing world having the goal of converting 14 67 million hectares of cropland to forests by 2010 4 4 million of which is on land with slopes greater than 25 and an additional soft goal of afforesting a roughly equal area of wasteland by 2010 pending successful completion it could represent a 10 20 increase in china s national forest area and a 10 decrease in current cultivated area in contrast to china s other forest sector policies slcp uses a public payment scheme that directly engages millions of rural households as core agents of project implementation and has the stated principals of volunteerism thus insofar as current or future de facto program implementation involves decentralized voluntary grassroots participation slcp represents an important departure from business as usual in how china manages its forest resources this work draws upon current available research of the program and uses a 2003 household and village level survey conducted by the center for chinese agricultural policy cas to examine program design implementation and outcomes to date results indicate that significant problems in design and implementation exist with these including shortfalls in subsidies delivered lack of respect of the principals of volunteerism and insufficient technical support and budgeting for local implementation costs more fundamentally some program goals appear to be based on common misperceptions regarding the linkages between forests and watershed services overall slcp contains both innovative elements volunteerism and the direct engagement of farmers as well as components that hark back to policies and mindsets of decades past the program s top down simplified contract structure lack of sufficient consultation with local communities and rural households and campaign style mobilization the paper concludes by providing four main suggestions to improve the program 1 increase local community input in design and implementation and ensure that households have full autonomy in participation choice 2 improve technical support and budgeting for local administrative costs and capacity building 3 clarify the environmental services targeted and verify the measures needed to acquire these services and 4 integrate slcp into an overall package of complementary policies aimed at the rural sector

effect of eco compensation schemes on household income structures and herder satisfaction lessons from the grassland ecosystem subsidy and award scheme in inner mongolia the grassland ecosystem subsidy and award scheme gesas is a key set of policy instruments designed to improve grassland condition and herder livelihoods in china this paper uses a structural equation modelling sem approach to investigate the impacts of gesas on livestock practices herder incomes and employment and overall herder satisfaction in inner mongolia the findings reveal that more intensive use of on farm inputs mediated the effects of lower stocking rate under the scheme on on farm income conversely gesas had a direct and negative impact on off farm income overall the findings do highlight the incentive role of gesas on herder decisions but also indicate a level of dissatisfaction among herders as the level of compensation is insufficient to cover the extra effort expended by herders and does not meet the livelihood expectations of most herders

convertible bond design and capital investment the role of call provisions if firms issue convertible securities to facilitate sequential investment the securities should be engineered to give sufficient flexibility to accommodate timing of follow on investment we examine call provisions in convertible bonds and argue that firms with investment options expected to expire sooner later will offer weaker stronger call protection we find that issues with weak or no call protection are offered by firms that invest greater amounts soon after issuance than those issuing convertibles with strong protection moreover capital expenditure levels during the 5 year period following issuance are inversely related to the length of call protection periods most convertible bonds and notes have call provisions and most provisions have important qualifications or protection broadly speaking convertibles may have absolute protection not callable hard call protection noncallable for a specified period provisional or soft call protection callable if certain conditions on stock price are met or no protection callable anytime in this study we investigate the relations between the strength and length of call protection and firms subsequent investment behavior our hypothesis is a natural implication of the sequential financing motive for convertible debt financing for example in mayers 1998 firms finance their planned multistage investment programs with convertibles besides mayers sequential financing motive other explanations for convertible financing include theories based on post issuance risk shifting jensen and meckling 1976 green 1984 heterogeneous risk assessment brennan and schwartz 1988 and asymmetric information stein 1992 in a recent study lewis rogalski and seward 2001 offer an explanation based on equity market rationing stein s 1992 model has at least an implicit role for callability but we believe mayers explanation has direct implications for the nature of call provisions that we examine here he argues that convertible financing is well suited to

why is there controversy regarding china s staple grain food market integration evidence and implication from price convergent club analysis there remains ongoing controversy regarding the degree to which chinese food markets are integrated some economists conclude that china s grain economy is well integrated while others argue that china s gradual reforms have led to fragmented domestic markets while others conclude that previous studies have produced mixed results to reconcile the debate this article models and analyses the behaviour of china s food grain retail markets by testing for the existence of the convergent price clustering clubs using appropriate econometric methods and price data over 1997 2010 the article finds evidence as to why the controversy remains by identifying a number of small divergent price clustering clubs where it is hard to conclude that china s food grain markets are fully integrated however given that large convergent clustering clubs were also identified it can be concluded that the degree to which chinese grain food retail markets are integrated is high this finding is important for those who plan to

assessing cost effectiveness of the conservation reserve program crp and interactions between the crp and crop insurance we examine the u s conservation reserve program crp enrollment design while accounting for the crp s interactions with the federal crop insurance program we find that the current crp is not cost effective despite its intent to balance benefits and costs based on crp contract level data we show that adopting a cost effective enrollment design and incorporating crop insurance subsidies into the crp s environmental benefits index would significantly increase the crp acreage environmental benefits and savings on crop insurance subsidies while leaving government outlay unchanged large geographical redistributions of crp acreage would also occur we further investigate the cost effective design s robustness to crp benefit misspecifications

environmental and distributional impacts of conservation targeting strategies abstract resource purchasing funds have become a major tool for environmental protection and resource conservation these funds use various strategies to target resources for conservation the choice of which may lead to striking differences in environmental performance this paper develops an analytical framework to analyze the impact of alternative targeting strategies on different interest groups including consumers producers labor and environmentalists we show that ignoring the output price effect of purchasing funds reduces environmental gain and in some cases may make a purchasing fund counterproductive and we argue that the optimal design of targeting criteria must consider the price feedback effect

credit based payments for ecosystem services evidence from a choice experiment in ecuador the original conceptualization of payments for ecosystem services pes promoted direct payments to motivate the provision of environmental public goods but market imperfections and behavioral considerations can mean that pes that reduce market constraints are preferred the main issue with the latter is how to include conditionality we propose credit based pes cb pes as an incentive that links an environmental condition with the reduction of a key market constraint through a choice experiment in ecuador cb pes was found to be a promising form of pes with multiple desirable qualities of an incentive as cited in the behavioral economics and pes literatures

differences and similarities between ecological and economic models for biodiversity conservation abstract in this paper we investigate an important obstacle which substantially complicates co operation between ecologists and economists but which has received little attention so far differences between the modelling approaches in economics and ecology to understand these differences 60 models addressing issues relevant to biodiversity conservation have been selected randomly from eight international economic and ecological journals the models have been compared according to a number of criteria including the models level of generality the mathematical techniques employed for formulation and solution of the models the level of complexity and the way time space and uncertainty are taken into account the economic models sampled are formulated and analysed analytically tend to be relatively simple and are mostly used to investigate general questions furthermore they often ignore space dynamics and uncertainty although some ecological models have similar properties there is also a substantial number of another type of ecological models that are relatively complex and analysed by simulation these models tend to be rather specific and often explicitly consider dynamics space and uncertainty the integrated ecological economic models are observed to lie in the middle between ecological and economic models an unexpected result is that they are not more complex than ecological and economic models as one could have expected from a simple merger of models from both disciplines but have an intermediate complexity

grain for green versus grain conflict between food security and conservation set aside in china summary this paper examines the conflict that may exist between conservation and food security in china policymakers and scholars are debating whether or not conservation set aside programs threaten food security to address the debate we describe china s conservation set aside program known as grain for green and compare it with similar programs outside of china we then use data that we collected to measure the production and price impacts of the program on china s grain economy since 1999 our simulations find that grain for green has only a small effect on china s grain production and almost no effect on prices or food imports

volunteer and satisfied rural households participation in a payments for environmental services programme in inner mongolia using survey data from inner mongolia this paper explores the role of stakeholder engagement in the implementation of the sloping land conversion programme a payments for environmental services pes programme designed to restore forest in degraded land based on the idea that volunteerism and satisfaction with the programme s outcome are two important components of the programme s viability we successively analyse the intensity of households participation in the programme and their reported satisfaction with its economic achievement which we relate to their stated volunteerism we show that households participation intensity in the slcp is primarily driven by land and location characteristics and that these findings hold true whether or not the households voluntarily enrolled in the programme moreover as far as participants satisfaction can be interpreted as an indicator of potential long term support for the programme our findings also support plausible sustainability for the programme

conservation payments liquidity constraints and off farm labor impact of the grain for green program on rural households in china this study evaluates the labor response of rural households participating in the grain for green program in china the largest payments for ecosystem services program in the developing world using a panel data set that we designed and implemented we find that the participating households are increasingly shifting their labor endowment from on farm work to the off farm labor market however the effects vary depending on the initial level of human and physical capital the results support the view that one reason why the participants are more likely to find off farm employment is because the program is relaxing households liquidity constraints

migration and the sending economy a disaggregated rural economy wide analysis abstract most economic research on migration impacts focuses on the households that send the migrants and get the remittances ignoring linkages with others in the sending economies this paper offers an alternative disaggregated economy wide perspective on migration and its impacts data from the 2003 mexico national rural household survey are used to calibrate a series of interacting rural household models nested within a general equilibrium model of the whole rural economy simulations reveal that the impacts of international migration and remittances on sending areas depend critically on the ways in which local markets transmit influences among households

feeding and fueling china in the 21st century abstract this paper addresses the questions to what extent will china become a significant net importer of food and fuel in the foreseeable future and what will be the impact of that import demand growth on international markets it first summarizes what standard trade and development economics and the experiences of other asian economies suggest we should expect of china and then examines china s experience to date before turning to some forecasts for the next decade or so our review suggests that before long china will become a significant net importer of both food and fuels especially petroleum contrary to chinese fears however becoming more interdependent with the rest of the world need not be threatening and it may even offer more supply security for china in the long run

irrigation agricultural performance and poverty reduction in china the overall goal of our paper is to understand the impact that irrigation in china has had on grain production and incomes in general and income and poverty alleviation in poor areas in particular the paper seeks to meet three objectives first we describe the relationship among irrigation status yields and household crop revenue second we seek to understand the magnitude and nature of the effect that irrigation has on yields and crop revenue finally we seek to understand the impact that irrigation has on incomes in poor areas our analysis shows that irrigation contributes to increases in yields for almost all crops and in income for farmers in all areas the importance of crop income in poor areas and the strong relationship between crop revenue and irrigation provides evidence of the importance of irrigation in past and future poverty alleviation in china we also show that in the majority of the villages that invested in new irrigation returns are positive even after accounting for increases in capital and production costs 2005 elsevier ltd all rights reserved

is a convertible bond call really bad news we test and reject the hypothesis that managers call in the money convertibles when they view a decline in the value of the firm as likely inconsistent with this view we find that insiders generally buy equity before conversion forcing calls also analysts tend to raise their earnings forecasts following a call thus our evidence supports the alternative hypothesis that the price decline immediately following conversion forcing calls is a purely transitory decline caused by the anticipated increase in the supply of equity indeed our evidence confirms that the initial price decline is reversed in the weeks following the announcement

prioritizing payment for environmental services using nonmarket benefits and costs for optimal selection abstract this article provides a practical applied analysis of optimal targeting in agricultural land preservation comparing the performance of four alternative targeting strategies nonmarket benefit data and hedonic cost estimates are used for parcels in sussex county delaware the results show that branch and bound optimization opt does not significantly outperform the much simpler benefit cost ratio targeting bcrt however significant losses of potential net benefits occur when applied methods overlook either benefits or costs in this application benefit targeting bt and cost targeting ct significantly underperform both opt and bcrt with bt underperforming all other methods

debt investment and product market competition a note on the limited liability effect abstract this paper extends a model by brander and lewis brander j lewis t 1986 oligopoly and financial structure the limited liability effect american economic review 76 956 970 on the relationship between capital structure investment and product market competition based on the limited liability effect of debt empirical papers see for example campello campello m 2003 capital structure and product markets interactions evidence from business cycles journal of financial economics 68 353 378 and chevalier chevalier j 1995a capital structure and product market competition empirical evidence from the supermarket industry american economic review 85 415 435 chevalier j 1995b do lbo supermarkets charge more an empirical analysis of the effect of lbos on supermarket pricing journal of finance 50 1095 1112 generally reject the limited liability theories in favor of the predatory theories because leverage leads to less investment and weaker product market competition this paper shows that when firms also have an investment choice leverage can lead to weaker product market competition in a limited liability model in addition non zero leverage is still optimal within this model based solely on the limited liability effect in predatory models debt is motivated by issues outside of product market concerns for example to solve an agency problem finally this model is also consistent with the investment decisions documented empirically

conditional cash transfers and payments for environmental services a conceptual framework for explaining and judging differences in outcomes we develop a conceptual framework elucidating the main determinants of the impact of conditional cash transfer cct and payments for environmental services pes programs using a simple multi agent model and evaluations of existing programs we show that 1 the share of the population who would meet the program s conditions in the absence of payments is a powerful predictor of program efficiency and that 2 program efficiency is eroded by selection bias people who already meet conditions self select into the programs at higher rates than others we then discuss possibilities for increasing efficiency and criteria for evaluating and choosing between ccts pes or other policy instruments

new evidence on the valuation effects of convertible bond calls this study examines the wealth effects of convertible bond call announcements on stock holders straight bondholders and called and non called convertible debtholders we docu ment that forced conversions are associated with a significant loss in firm value the results suggest that convertible call announcements can trigger both negative signal and wealth transfer effects we show that at least part ofthe negative effect on stock prices results from wealth transfer to straight bondholders our analysis also lends empirical validity to the common contention that called convertible bondholders suffer wealth expropriation due to the elimination ofthe premium the wealth effect on non called convertible debtholders is insignificant cross sectional analysis reveals that the negative signal effect is important in explaining bond stock and firm excess returns finally we present evidence that refutes the notion that bonds are called to relieve the firm from restrictive debt covenants

incremental reform and distortions in china s product and factor markets the purpose of economic reform is to reduce distortions and enhance efficiency however when reforms are partial and incremental individuals and local governments are often able to capture the rent inherent in the gradual transition process young 2000 warned that such rent seeking behavior might lead to increasing market fragmentation empirical studies have shown the opposite in the product market this article argues that as the rent from china s product market has been squeezed out due to deepening reforms rent seeking behavior may have shifted to the capital market further reforms are needed in the capital market to squeeze out these rent seeking opportunities just as those from the product and labor markets were squeezed out earlier

the role of forest related income in household economies and rural livelihoods in the border region of southern china quarterly socioeconomic data from 240 households are used to study the links between forest related income and rural livelihoods in southern china results show average forest related income shares of 31 5 which was predominantly derived from cultivated non timber sources forest related income was important to households at all income levels although lower income households were more dependent due to a lack of other sources higher income households monopolized off farm income and had more land than low income households forest related income could be increased by making forest land more accessible to the poor improving productivity and removing constraints to smallholder engagement in timber marketing

regional poverty targeting in china we evaluate the effectiveness of regional targeting in china s large scale poverty alleviation program begun in 1986 by analyzing a panel data set of all counties in china for the period 1981 1995 estimates of models of poor county designation and poverty fund allocation and newly defined targeting gap and targeting error measures show that political factors have affected targeting and that leakage has increased while coverage has improved only one of the three main programs is progressive growth model estimates find that poor county designation increased incomes per capita by 2 28 per year during 1985 1992 and 0 91 during 1992 1995 these results are relatively robust to redefining control groups using propensity score matching methods

targeting incentives to reduce habitat fragmentation the fragmentation of wildlife habitat has long been recognized as a principal threat to terrestrial biodiversity in this paper we develop a theoretical model to analyze the spatial targeting of incentives for the restoration of forested landscapes when land quality is spatially heterogeneous and wildlife habitat can be enhanced by reducing fragmentation we consider a regulator who uses subsidies to encourage the conversion of private agricultural land to forest on a pre defined set of landscapes the regulator can observe land use choices but not the opportunity costs on individual land parcels the important insight to emerge from the theoretical analysis is that solutions at or near corners are a strong possibility on each landscape either none or all of the agricultural land should be converted to forest corner solutions are directly linked to the spatial process determining habitat benefits to verify the theoretical insight we present a simulation of the effects of incentive based policies on the spatial distribution of forests in south carolina the empirical methodology integrates an econometric model of land use change with gis based landscape simulations the empirical findings strongly support our conjecture regarding corner solutions and the optimal targeting policy is shown to produce substantial welfare gains over a spatially uniform incentive

transactions costs and agricultural household supply response we develop and estimate a model of supply response when transactions costs create a situation where some producers buy others sell and others do not participate in markets we present two rationales for why producing households may have different relationships to the market proportional and fixed transactions costs using data on mexican corn producers we estimate an empirical model that allows for separate tests of the significance of both types of transactions costs revealing that both fixed and proportional transactions costs matter for the estimation the results provide consistent estimates of supply elasticity and measures of the relative importance of factors determining both proportional and fixed transactions costs

paying for the hydrological services of mexico s forests analysis negotiations and results abstract mexico faces both high deforestation and severe water scarcity the payment for hydrological environmental services psah program was designed to complement other policy responses to the crisis at the interface of these problems through the psah the mexican federal government pays participating forest owners for the benefits of watershed protection and aquifer recharge in areas where commercial forestry is not currently competitive funding comes from fees charged to water users from which nearly us 18 million are earmarked for payments of environmental services applicants are selected according to several criteria that include indicators of the value of water scarcity in the region this paper describes the process of policy design of the psah the main actors involved in the program its operating rules and provides a preliminary evaluation one of the main findings is that many of the program s payments have been in areas with low deforestation risk selection criteria need to be modified to better target the areas where benefits to water users are highest and behavior modification has the least cost otherwise the program main gains will be distributive but without bringing a pareto improvement in overall welfare

a laissez faire approach to monetary stability this paper develops some diverse hints for a new monetary system offered separately by fischer black eugene fama and robert e hall for reasons that will become evident though we should perhaps say payments system instead of monetary system none of the economists mentioned has actually proposed the particular system set forth here nor examined all its properties and we call it the bfh system not to implicate them but only to give credit for some component ideas and to have a convenient label l regardless of who if anyone may actually advocate the system contemplating it is instructive it illuminates by contrast some characteristics of our existing and recent systems

redefining payments for environmental services abstract the environmental economics and the ecological economics perspectives on payments for environmental services pes propose rather different views on how to define pes its key elements and on the role of pes in ecosystem conservation and rural development this paper compares these two perspectives and addresses the following questions what is an appropriate definition of pes grounded in the theory and practice underlying it what are the key design elements of pes what should the scope of pes be given the possible trade offs between efficiency and equity it is found that pes schemes should focus on cost effectiveness and best practice for positive livelihood impacts pes schemes should be transparent and provide additional services with conditional payments to voluntary providers

impact of a regional payment for ecosystem service program on the livelihoods of different rural households abstract payments for ecosystem services pes is popular despite little empirical evidence of their effectiveness in poverty alleviation using survey data on rural households livelihoods in changting county southeast china we evaluate the comprehensive and dynamic livelihood impacts of pes on participants and nonparticipants results show that pes programs have been beneficial for participants however negative impacts have been found for nonparticipants in detail the participants livelihood assets are greatly consolidated through a series of policies and institutions these institutions have empowered participants to access to natural resources and excluded the others participants livelihood strategies and sustainable livelihoods are further shaped and mediated by these institutions instead nonparticipants are excluded from the project and prohibited to access to natural resources their livelihood assets and strategies are negatively influenced by resources relocation given the minimal trickle down benefits and remarkable negative impacts the nonparticipants livelihoods are overall adversely affected by the project our study highlights the importance of disaggregated household analysis and dynamic perspective in evaluating livelihood impacts of pes policy strategies should consider household heterogeneity livelihood framework and dynamic impacts in related environmental and development programs

the sloping land conversion program in china effect on the livelihood diversification of rural households summary through addressing the motivations behind rural households livelihood diversification this paper examines the effect of the sloping land conversion program slcp on livelihood diversification using a longitudinal household survey data set spanning the overall implementation of the slcp our results show that the slcp works as a valid external policy intervention to increase rural livelihood diversification in addition the findings demonstrate that the implementation of the slcp has had heterogeneous effects on livelihood diversification across different rural income groups the lower income group was more affected by the program in terms of income diversification

the spillover effects of biofuel policy on participation in the conservation reserve program abstract this paper studies the spillover effects of rising biofuel production on participation in the conservation reserve program landowner participation decisions are modeled using a real options framework we develop a land use decision model that captures biofuel driven structural changes in market demand and derive threshold conditions that trigger participation in the program we then quantify the impacts of biofuel production on participation at both the national and state levels using monte carlo simulations the model is also used to analyze how changes in the persistence of the biofuel production boom and in the volatility of farming returns affect conservation participation decisions policy implications of the results are discussed

efficiency equity tradeoffs in targeting payments for ecosystem services this article develops an analytic framework to analyze the tradeoff between economic efficiency and distributional equity in targeting payments for ecosystem services pes it also proposes an empirical procedure to trace out the efficiency equity frontier where the program is pareto optimal in the sense that it cannot be improved upon to achieve either higher efficiency or distributional equity without compromising the other we apply the procedure to the conservation reserve program crp the largest pes program in u s history to analyze a whether it is possible to improve both the efficiency and the distributional equity of the program and b what the choice made by crp administrators implies about the political economic balance results reveal that a crp administrators forfeited about 9 of efficiency for an 18 23 improvement in distributional equity depending on the equity indicator used in the eighteenth signup of the crp b reducing the maximum allowable rental rate for all contracts would improve efficiency at the cost of distributional equity c reducing the maximum county enrollment cap would reduce efficiency without generating much improvement in distributional equity and d the crp targeting criterion could be redesigned to achieve both higher efficiency and higher distributional equity

habitat and open space at risk of land use conversion targeting strategies for land conservation funds available to purchase land and easements for conservation purposes are limited this article provides a targeting strategy for protecting multiple environmental benefits that includes heterogeneity in land costs and probability of land use conversion by incorporating spatially explicit land use change and hedonic price models this strategy is compared to two alternative strategies that omit either land cost or conversion threat based on dynamic programming and monte carlo simulations with alternating periods of conservation and development we demonstrate that the positive correlation between land costs and probability of land use conversion affects targeting efficiency using parcel data from sonoma county california

the complexity of exchange the computational complexity of two classes of market mechanisms is compared first the walrasian interpretation in which prices are centrally computed by an auctioneer recent results on the computational complexity are reviewed the non polynomial complexity of these algorithms makes walrasian general equilibrium an implausible conception second a decentralised picture of market processes is described involving concurrent exchange within transient coalitions of agents these processes feature price dispersion yield allocations that are not in the core modify the distribution of wealth are always stable but path dependent replacing the walrasian framing of markets requires substantial revision of conventional wisdom concerning markets

poverty risks and national parks policy issues in conservation and resettlement summary is the conflict between biodiversity conservation and poverty reduction which frequently arises in park creation programs insoluble the authors report empirical evidence from 12 case studies from six countries which are analyzed through the conceptual lens of the impoverishment risks and reconstruction model for involuntary resettlement the research concludes conservatively that parks in the congo basin have already displaced and impoverished about 120 150 000 people and that more will be displaced if this approach continues despite its deleterious outcomes the authors argue that the park establishment strategy predicated upon compulsory population displacement has exhausted its credibility and compromised the cause of biodiversity conservation by inflicting aggravated impoverishment on very large numbers of people they recommend that the concerned governments should desist using the eviction approach the alternative course proposed by the authors is to replace forced displacements with a pro poor strategy that pursues double sustainability to protect both the biodiversity and people s livelihoods at the same time 2006 elsevier ltd all rights reserved

towards a unified scheme for environmental and social protection learning from pes and cct experiences in developing countries environmental protection and poverty alleviation in the developing world are usually heralded as joint objectives however these two goals are often associated with different sectoral policy instruments while so called payments for environmental services pes are increasingly being promoted for environmental protection poverty alleviation is increasingly addressed by conditional cash transfers cct program these instruments although aimed to achieve distinct objectives have a number of similarities and challenges in their design and implementation phases this paper elaborates on these similarities and develops a unifying generic framework that is used to discuss the extent to which both approaches could be unified

two tier land tenure system and sustained economic growth in post 1978 rural china abstract the two tier land tenure system has been widely blamed for the problems in land allocation and in land specific investment observed in the postreform rural china greater privatization of property rights in land has been proposed to enable productive farmers to acquire more land to promote land circulation to improve farmers access to credit and to encourage farm investment it is argued here that in the presence of multiple market distortions land privatization is unlikely to provide a solution to the agricultural problems rather an approach which refines the existing framework of the two tier ownership system offers more promise

success and failure of reform insights from the transition of agriculture this paper analyzes the linkages between the reform strategies in transition countries and economic performance the authors focus on agriculture because of the sharpness of the policy changes fundamental differences among countries and relative simplicity of agricultural relationships the authors document post reform performance in the transition countries of asia and europe the authors show how a pricing reform and subsidy reductions b land rights reform and policies that affect farm restructuring and c the presence institutions that facilitate exchange either markets or market substitutes affect output and productivity the paper ends with general lessons on reforms and transition

will the biosafety protocol hinder or protect the developing world learning from china s experience abstract uncertainties about the effect of biosafety protocol bsp on global agricultural trade have caused concern among those with a stake in agrifood imports and exports the primary goal of this paper is to analyze the potential economic impacts of the bsp on both importing countries with a specific emphasis on china and exporting countries of soybean and maize the results show that in absolute terms the bsp will require large investments internationally and will induce compliance costs the bsp will increase the international price and domestic production in importing countries and lower international trade and domestic production in the exporting countries in absolute terms the impacts are large amounting for each commodity into the tens of millions of dollars and varying largely among different scenarios but in the percentage the impacts are small much smaller impacts are found in china because china has already invested in a system that provides almost all of the services that could be required by the bsp other developing nations may need more help and that it will be more costly

moving toward markets labor allocation in rural china abstract china s economic reforms have brought rapid growth in rural off farm employment raising questions about the assumption that rural china is labor surplus and has poorly functioning factor markets we investigate this by testing for separability between household labor demand and supply using panel data we find that separability is rejected overall indicating that factor markets remain underdeveloped nonseparability however is associated with labor surplus in some areas and labor shortage in others moreover separability holds where substantial employment opportunities exist in the wider township suggesting that such employment promotes competitive allocation within villages as well as the inter village movement of resources

how sustainable are sustainable development programs the case of the sloping land conversion program in china summary this paper undertakes a comprehensive assessment of the long run sustainability of one of the world s largest sustainable development programs the slopping land conversion program slcp in china under different plausible post slcp scenarios the analysis is based on farmer contingent behavior post program land and labor decisions as well as choice experiment data our econometric results highlight the main obstacles to the program s sustainability which include specific shortfalls in program implementation and certain institutional constraints namely tenure insecurity and poor land renting rights the use of a choice experiment also reveals unique evidence on rural households preferences over tenure reform in china

evaluating water policy scenarios against the priorities of the rural poor summary a stated choice method evaluates how well water policy responds to the preferences of the rural poor in south africa household priorities to experimental scenarios of water resource and water services attributes are investigated in two communities with poor water access in a semi arid zone results identify improved water accessibility as the most important intervention for social welfare gains particularly benefiting female water collectors a latent class specification reveals two sub groups with different weighted preferences this specification reinforces the primacy of domestic water access and also identifies a smaller but significant group with preferences for water availability for kitchen garden irrigation

a joint framework for analysis of agri environmental payment programs this article presents an approach for simultaneously estimating farmers decisions to accept incentive payments in return for adopting a bundle of environmentally benign best management practices using the results of a multinomial probit analysis of surveys of over 1 000 farmers facing five adoption decisions in a voluntary program we show how the farmers perceptions of the desirability of various bundles change with the offer amounts and with which practices are offered in the bundle we also demonstrate an estimator for the mean minimum willingness to accept for the adoption of a practice conditional on the cost share offers for other practices agri environmental payment programs play an important part in improving the environmental performance of agriculture claassen and horan batie lynch and smith smith feather and cooper claassen et al federallevel interest in developing these programs is currently strong for example the 2002 farm act calls for a five fold increase in funding for the usda s environmental quality incentives program eqip this article focuses on voluntary programs designed along the lines of the eqip which provides incentive payments to encourage producers to adopt environmentally benign land management practices such as nutrient management manure management and integrated pest management for policy making purposes it would be useful to know the sensitivity of the producer s decision to enroll in response to a schedule of potential incentive payments and to which practices are bundled together such information can be used to assess the costs of encouraging farmers to try various environmentally benign management practices commonly known as best management practices or bmps eqip offers the farmer a suite of bmps to choose from existing published research cooper and keim modeled the probability of farmer adoption of bmps as a function of the incentive payment with each practice be

choice for goods under threat of destruction abstract the choices related to preservation often involve consideration of the fate of the non selected land yet theory traditionally assumes that the fate of non selected goods does not influence consumers preferences results from a framed field experiment involving the private choice of wine show that consumer preferences can dramatically shift for items under the threat of imminent destruction this shift upwards of 58 increase may explain why conservation professionals despite decades of scientific evidence have failed to adopt cost effective techniques that would yield large conservation benefits at no additional cost interestingly economists exhibit similar preference shifts

the economics of a public fund for environmental amenities a study of crp contracts the problem of targeting crp purchases to buy environmental amenities under productivity and environmental heterogeneity is considered gini coefficients and lorenz curves are used to measure the effectiveness of spending under alternative targeting criteria the environmental benefits considered are water erosion wind erosion surface water quality and wildlife habitat the three alternative targeting criteria examined include purchasing land according to i the benefit to cost ratio ii the level of benefits and iii the level of cost results indicate that the degree of variability and correlation determine the extent to which suboptimal targeting achieves a significant portion of available environmental benefits

the effectiveness of payments for environmental services we adopt a theory based approach to synthesize research on the effectiveness of payments for environmental services in achieving environmental objectives and socio economic co benefits in varying contexts our theory of change builds on established conceptual models of impact pathways and highlights the role of 1 contextual dimensions e g political institutional and socio economic conditions spatial heterogeneity in environmental service values and provision costs and interactions with pre existing policies and 2 scheme design e g payment type and level contract length targeting and differentiation of payments in determining environmental and socio economic outcomes to shed light on the overall effectiveness of payment schemes and its determinants we review counterfactual based empirical evaluations comparative analyses of case studies and meta analyses our review suggests that program effectiveness often lags behind the expectations of early theorists however we also find that theory has advanced sufficiently to identify common reasons for why payment schemes fail or succeed moreover payment schemes are often rolled out along with other policy instruments in so called policy mixes advances in theory and evaluation research are needed to improve our understanding of how such policy mixes interact with the targeted social ecological systems 2017

china s regional agricultural productivity growth in 1985 2007 a multilateral comparison1 in this study we estimate total factor productivity tfp growth as well as multilateral tfp index for 25 contiguous china provinces over the 1985 2007 period agricultural output growth for each province was decomposed into tfp growth and input growth where input growth was further disaggregated into contributions from growth of labor capital land and intermediate goods over the study period tfp growth contributed 2 7 percentage points to output growth annually which was slightly higher than the input growth contribution of 2 4 percentage points per annum on average the annual rate of productivity growth peaked during 1996 2000 at 5 1 it slowed in 2000 2005 to a rate of 3 2 per annum and declined in the most recent years 2005 2007 to 3 7 differences in productivity among regions persisted over the entire period the tendency toward faster tfp growth in relatively well off coastal regions may imply a widening of regional inequality

investment incentives debt and warrants abstract this paper models and characterizes investment incentive problems associated with debt financing the decision problem of residual claimants is explicity formulated and their investment policies are characterized the paper also analyzes the use of conversion features and warrants to control distortionary incentives these claims reverse the convex shape of levered equity over the upper range of the firm s earnings and this mitigates the incentive to take risk it is shown that under certain conditions such claims can be constructed to restore net present value maximizing incentives and simultaneously meet the financing requirements of the firm

participation in the world s first clean development mechanism forest project the role of property rights social capital and contractual rules abstract clean development mechanism cdm forest projects are perceived as an attractive way to both help mitigate climate change and transfer income to rural poor however to engender participation of small scale producers a cdm forest project must offer sufficient incentives while minimizing their costs of participation all the while respecting the need for additionality property rights social capital and contractual rules are critical in the success of cdm forest projects in this paper we ask what factors affect participation in the world s first cdm project established in guangxi province china using village level surveys we find that although the project facilitates participation through carbon pooling and a share holding system much of the project land remains unforested we find that the primary reasons for the unforested regions are constrained contractual rules property rights allocation disputes and low levels of social capital in some villages

reconciling theory and practice an alternative conceptual framework for understanding payments for environmental services article i nfo this article provides an alternative and novel theoretical approach to the conceptualization and analysis of payments for environmental services pes we devote special emphasis to institutional and political economy issues which have been somewhat neglected in the literature on pes we argue that the coasean and pure market approach dominating the conceptualization of pes in the literature cannot be easily generalized and implemented in practice by contrast taking into account complexities related to uncertainty distributional issues social embeddedness and power relations permits acknowledging the variety of contexts and institutional settings in which pes operate the alternative approach presented in this introductory article to the special section may be more appealing to pes practitioners since while avoiding restrictive and prescriptive standpoints it allows some key sources of complexities they usually deal with on the ground to be more easily understood

on market mediated emissions and regulations on life cycle emissions abstract we analyze the use of life cycle assessment lca as a regulatory tool using biofuel regulations as an illustrative example a regulatory context calls for a consequential lca clca of a policy as opposed to an attributional lca alca of a product in performing clca issues of scale price effects technology and policy in the counterfactual state of the world strategic behavior policy horizon etc need consideration this appears to increase both uncertainty in estimates and the cost of performing lca we suggest heuristics for determining vulnerability to harmful indirect effects at an early stage in the policy process and discuss alternative policies to limit harmful indirect effects without engaging in the full effort of computation and selection of a central estimate for uncertain outcomes

hotelling s theory enhancement and the taking of the redwood national park we estimate a reduced form model of the redwood timber industry that is consistent with hotelling s exhaustible resource theory the consequences for this theory of various assumptions about the elasticity of expectations are derived the estimated equations are used to test the hypotheses about expectations we also use these equations to find the amount that owners of redwood not taken for the redwood national park benefited from the park s establishment

opening of china s trade labour market reform and impact on rural wages government policy in china supports urban wages at the expense of returns to farm labour a model is developed to estimate how wto accession and complementary labour market reform will influence factor returns in china with wto membership a larger cut in manufacturing tariffs compared to agriculture will improve agriculture s terms of trade and will raise the agricultural wage complementary labour market reforms will further boost farm wages as labour exits agriculture in large numbers we estimate that wto membership and complementary labour market reforms will result in a decline in the agricultural labour force by about 25 per cent

hidden impact household saving in response to a poor area development project abstract the possibility that poor households may prefer to save the income gains from a development project raises concerns about how well standard evaluation methods using data collected over relatively short periods can capture the true welfare impacts by the widely used difference in difference method the southwest china poverty reduction project had little current impact on the proportion of people in beneficiary villages consuming less than us 1 day despite a public outlay of us 400 million however the program had much larger impacts on incomes than consumptions uncertainty about the project s future impact probably made it hard for participants to infer the gain in permanent income so they saved a high proportion of the current income gains

investor protection and convertible debt design abstract an important issue that firms consider when designing convertible debt is to specify security features such as conversion ratio maturity date and call period following lewis et al lewis m rogalski r seward j 2003 industry conditions growth opportunities and market reactions to convertible debt financing decisions journal of banking and finance 27 153 181 we employ a single measure that simultaneously considers all of these features the expected probability measured at issue date that the convertible will be converted to equity at maturity we find that firms in countries with stronger shareholder rights issue convertible debt with a higher expected probability of converting to equity the positive association between the expected probability of conversion and shareholder rights is less pronounced in firms for which ownership structures create potentially high managerial agency costs specifically in countries with stronger shareholder rights firms with higher separation of control rights and cash flow rights tend to issue convertibles with lower probability of conversion furthermore we find that large non management block ownership strengthens the likelihood of issuing convertible debt with higher probability of conversion in countries with stronger shareholder rights in contrast firms in countries with stronger creditor rights issue convertibles with lower probability of conversion we also document that the negative association between creditor rights and probability of conversion is more pronounced in firms with higher separation of control rights and cash flow rights

interactions between agricultural and environmental policies a conceptual framework agricultural policy has a well documented impact on farmers production decisions and those decisions land water and agricultural chemical use may in turn affect the environment there is a public perception that existing agricultural policies are linked to agricultural pollution as exemplified by the conclusions of the recent national research council report alternative agriculture 1989 there is only limited theoretical or empirical research addressing these linkages however this paper develops a conceptual framework that can be used to analyze the interactions between agricultural and environmental policies and pollution this framework integrates physical and economic models at a disaggregate level necessary to capture the heterogeneity of the physical environment and the economic behavior of farmers following e hochman and d zilberman 1978 the disaggregate units can be statistically aggregated to a level useful for policy analysis agricultural and environmental policies can be categorized according to their effects on the intensive and extensive margins combining the different policy instruments with the microeconomic heterogeneity we find that existing agricultural and environmental policies can have either positive or negative effects of nonpoint source pollution to infer an aggregate effect requires data that do not currently exist our framework provides a basis for empirical investigations of these effects given adequate data moreover we find that agricultural policy instruments can be used to mitigate pollution if used appropriately
