income distribution in agriculture a unified approach this paper develops a class of partial equilibrium models capable of analyzing in a unified way a number of market transmitted distributional consequences of a variety of exogenous shocks in agriculture the shocks include technical change neutral or biased changes in the supply of agricultural inputs or in the demand for agricultural outputs and government interventions the models accommodate more than two primary factors of production and more than one region with or without constraints on factor mobility

how much damage will climate change do recent estimates two reasons to be concerned about climate change are its unjust distributional impact and its negative aggregate effect on economic growth and welfare although our knowledge of the impact of climate change is incomplete and uncertain economic valuation is difficult and controversial and the effect of other developments on the impacts of climate change is largely speculative the authors find that poorer countries and people are more vulnerable than are richer countries and people a modest global warming is likely to have a net negative effect on poor countries in hot climates but may have a net positive effect on rich countries in temperate climates if one counts dollars the world aggregate may be positive if one counts people the world aggregate is probably negative negative impacts would become more negative and positive impacts would turn negative for more substantial warming the marginal costs of carbon dioxide emissions are uncertain and sensitive to assumptions that partially reflect ethical positions but are unlikely to be larger than 50 per tonne carbon

modern rice technology and regional wage differentials in the philippines abstract fear has been widely expressed that the modern rice varieties have created large disparities in regional income distribution as the productivity gap between favorable and unfavorable rice production environments widened due to differential technology adoption throughout south and southeast asia over the last two decades technology affects the income of farm population directly through its effects on productivity and factor use and indirectly through its effect on factor prices in particular the ultimate distributional impact of modern varieties will critically depend on the interregional labor market adjustments through migration in response to regional wage differentials created by the differential technology adoption since labor is the main resource of the majority of the rural population we studied favorable and unfavorable rice growing villages in the philippines and found that adoption of modern varieties during the 1970s was positively related to population growth rate contrary to popular belief no association was observed between wage rates and adoption of modern varieties as of 1986 these findings support the hypothesis that the differential adoption of modern rice varieties induced interregional labor migration toward equalization of wage income across different production environments

modelling long run scenarios this paper intends to draw overall lessons from a long term study on co2 emission in france a country with a rather low energy gdp ration and in which transition to non fossil based production of electricity has been achieved more generally it points out the importance of possible bifurcation effects and draws methodological and policy implications from these statements it discusses modelling approaches to the linkages between energy and the rest of economy and addresses the issue of difficulties in cost assessment analysis in the presence of several baseline scenarios finally it proposes a more encompassing definition of no regrets policies

uncertainty and endogenous technical change in climate policy models until recently endogenous technical change and uncertainty have been modeled separately in climate policy models in this paper we review the emerging literature that considers both these elements together taken as a whole the literature indicates that explicitly including uncertainty has important quantitative and qualitative impacts on optimal climate change technology policy

rural income dynamics and poverty reduction in thai villages from 1987 to 2004 this article aims to examine the factors contributing to the increase in household income and the corresponding reduction in poverty in rural thai villages from 1987 to 2004 by employing household panel data it is found that there has been a significant structural shift of household income away from farm to nonfarm income sources as well as a reduction in the income gap and the difference in poverty incidence between favorable and unfavorable regions such decreases in poverty and its regional gap have been associated with the declining importance of income accrued to farm land measured by farm size and the availability of irrigation and with the increasing importance of human capital measured by the proportion of working members who have graduated from post lower secondary schools such findings indicate that the success in rural poverty reduction in thailand has resulted from the development of the rural nonfarm sector coupled with the improvement of the schooling levels of the rural population

spatial cost benefit thinking in multi functional forestry towards a framework for spatial targeting of policy interventions abstract many countries now actively encourage land use change for the provision of multiple benefits specifically including non market benefits often such policies have been poorly designed because of a lack of understanding of the spatial distribution of the potential costs and especially non market benefits from land use change as with market goods the potential yield of non market goods and services from land use can be highly spatially variable in recent years more and more studies on the economic aspects of natural resources have started to make use of geographical information systems gis what is yet lacking is the systematic adoption of a framework for the spatial targeting of policy interventions which can be used to improve decision making in terms of effectiveness efficiency equity or public acceptability this paper uses existing studies in forestry to present such a framework and discusses its potential uses and limitations as a new standard tool to inform multi functional land use decisions

green revolution land reform and household income distribution in the philippines income of agricultural households consists of returns to labor capital and land from farming supplemented mainly by labor earnings from nonfarm sources agricultural technology affects farmers income through its effect on factor demands and factor prices which in turn induce changes in the allocation of farmers own resources to different uses income from farming is also affected by village institutions such as land tenure which governs the distribution of income between landlords and tenants as well as resource allocations

income diversification and risk does ownership matter an empirical examination of indian banks abstract we examine the impact of ownership on income diversification and risk for indian banks over the period 2001 2009 we investigate both the determinants of non interest income and the impact of diversification on various profitability and insolvency risk measures for public sector private domestic and foreign banks we document that ownership does matter in the pursuit of non interest income relative to private domestic banks public sector banks earn significantly less fee income while foreign banks report higher fee income public sector banks with higher levels of governmental ownership are significantly less likely to pursue non interest income sources fee based income significantly reduces risk measured by profitability variables for public sector banks default risk is also reduced for these banks from a regulatory perspective it appears that diversification benefits india s public sector banks our research has implications for the changes in the risk profile for banks in emerging banking markets pursuing non interest revenue sources

welfare specifications and optimal control of climate change an application of fund the sensitivity of the optimal control of carbon dioxide emissions to the specification of the social welfare function is systematically explored using the fund model increasing risk aversion emphasises climate change damages relative to emission reduction costs but at the same time increases the discount rate of consumption without international co operation the discount rate effect dominates so that optimal control decreases with increasing risk aversion with international co operation optimal control first increases then decreases with increasing risk aversion since climate change falls heaviest on the poor optimal control increases with increasing inequity aversion full fledged intergenerational welfare functions on the one hand emphasise climate change damages but on the other hand place more weight on current poorer generations in fund the two tendencies almost cancel

carbon capture and storage as a corporate technology strategy challenge latest estimates suggest that widespread deployment of carbon capture and storage ccs could account for up to one fifth of the needed global reduction in co2 emissions by 2050 governments are attempting to stimulate investments in ccs technology both directly through subsidizing demonstration projects and indirectly through developing price incentives in carbon markets yet corporate decision makers are finding ccs investments challenging common explanations for delay in corporate ccs investments include operational concerns such as the high cost of capture technologies technological uncertainties in integrated ccs systems and underdeveloped regulatory and liability regimes in this paper we place corporate ccs adoption decisions within a technology strategy perspective we diagnose four underlying characteristics of the strategic ccs technology adoption decision that present unusual challenges for decision makers such investments are precautionary sustaining cumulative and situated understanding ccs as a corporate technology strategy challenge can help us move beyond the usual list of operational barriers to ccs and make public policy recommendations to help overcome them

intergenerational transfers in philippine rice villages gender differences in traditional inheritance customs abstract this paper examines education land and nonland asset transfers from parents to children in five rice villages in the philippines a model with family fixed effects explains transfers better than either individual heterogeneity or observed parent and child characteristics without family fixed effects families facing different land constraints exhibit significantly different patterns of educational investment in children in a subsample with completed inheritance daughters receive less education land and total inheritance but are compensated with nonland assets parents also exhibit preferential behavior towards children of the same gender daughters of better educated mothers receive more land nonland assets and total inheritance better educated fathers give land preferentially to sons but favor daughters in education

contagion and banking crisis international evidence for 2007 2009 abstract policy makers aim to avoid banking crises and although they can to some extent control domestic conditions internationally transmitted crises are difficult to tackle this paper identifies international contagion in banking during the 2007 2009 crisis for 54 economies we identify three channels of contagion systematic idiosyncratic and volatility and find evidence for these in 45 countries banking crises are overwhelmingly associated with the presence of both systematic and idiosyncratic contagion the results reveal that crisis shocks transmitted from a foreign jurisdiction via idiosyncratic contagion increase the likelihood of a systemic crisis in the domestic banking system by almost 37 percent whereas increased exposure via systematic contagion does not necessarily destabilize the domestic banking system thus while policy makers and regulatory authorities are rightly concerned with the systematic transmission of banking crises reducing the potential for idiosyncratic contagion can importantly reduce the consequences for the domestic economy

directed technical change with capital embodied technologies implications for climate policy abstract we develop a theoretical model of directed technical change in which clean zero emissions and dirty emissions intensive technologies are embodied in long lived capital stocks switching from dirty to clean innovation leads to ongoing reductions in the relative costs of producing clean investment goods making them ever cheaper to purchase and so encouraging clean investment at the same time falling replacement costs imply falling asset values consequently continuing innovation in capital embodied clean technologies also generates obsolescence costs which are borne by users of clean capital the negative effect of obsolescence costs on demand for clean investment and consequently on the speed of transition to clean growth has been neglected in the literature on directed technical change we show theoretically and using numerical simulations that optimal policies differ in our model of embodied technological change relative to an otherwise comparable model of disembodied technological change with embodied technologies i optimal emissions taxes start higher and rise faster ii much higher clean research and development subsidies are required to effect the switch to clean innovation and iii climate damages under optimal policies are greater we suggest that more attention should be paid to the role of obsolescence costs in modelling transitional effects of climate policies

determinants and consequences of land reform implementation in the philippines abstract unlike the experience of other developing countries land reform in the philippines has been successful in converting many of share tenants to land reform beneficiaries this study indicates that the implementation of land reform is positively associated with yield growth made possible by the adoption of modern seed fertilizer technology a major reason underlying such association is considered to be an increased economic interest of tenants in land reform arising from divergence of rental value of land from leasehold rent and amortization fees prescribed by law

foreign bank diversification and efficiency prior to and during the financial crisis does one business model fit all diversified and focused business models may affect foreign bank efficiency differently we investigate whether there is an optimal business model along three business dimensions assets funding and income and which business model is optimal for foreign banks in a financial center we apply recently developed non parametric methods with bootstrap to estimate group efficiency to test for differences across groups and finally to analyze the link between bank efficiency and diversification measures using luxembourg bank data that include the financial crisis we find that there is no unique business model the most efficient business model appears to be a focused asset funding and income strategy banks organizational forms play a role branches may be preferable to subsidiaries prior to the financial crisis whereas bank subsidiaries perform better than branches during the financial crisis however branches diversified in assets funding and income exploit efficiency advantages during the financial crisis

fundamentals panics and bank distress during the depression we assemble bank level and other data for fed member banks to model determinants of bank failure fundamentals explain bank failure risk well the first two friedman schwartz crises are not associated with positive unexplained residual failure risk or increased importance of bank illiquidity for forecasting failure the third friedman schwartz crisis is more ambiguous but increased residual failure risk is small in the aggregate the final crisis early 1933 saw a large unexplained increase in bank failure risk local contagion and illiquidity may have played a role in pre 1933 bank failures even though those effects were not large in their aggregate impact

technological change and uncertainty in environmental economics abstract technological change is widely believed to play a crucial role in mastering the challenges of man made climate change the drivers and impacts of technological change have therefore become an important research issue in the field of climate economics while models to analyze the interactions between economy energy and the environment initially treated technological change as exogenous more recent modeling approaches often represent technological change as endogenously induced typically models of induced technological change in climate economics are based on perfect foresight in a deterministic world however both technological change and climate impacts are subject to large uncertainties that may substantially affect the design of efficient climate policies against this background the special issue presents five articles contributing to the study of uncertainty and technological change in climate change economics

evaluating the integration of contiguous discontinuous markets this paper applies the concepts of structural models of markets market integration and market discontinuity to show that discontinuous markets alter the integration characteristics of continuous markets when analyzing systems of contiguous markets some of which are discontinuous it appears that the continuous markets are less well integrated when the discontinuous markets are operating than when they are not operating

carbon trading in the policy mix the kyoto protocol is stimulating the development of emissions trading schemes at the national and international levels these are being introduced alongside existing policy instruments such as carbon taxes and negotiated agreements leading to complex problems of policy interaction but the topic of policy interaction remains under researched this paper aims to improve understanding of such interactions by examining the conditions under which a cap and trade scheme for carbon dioxide emissions may usefully coexist with carbon energy taxes support mechanisms for renewable electricity and policies to promote energy efficiency the paper argues that each of these instrument combinations may be acceptable provided they contribute to either improving the static or dynamic efficiency of the trading scheme or delivering other valued policy objectives but since the coexisting instruments may raise overall abatement costs while contributing nothing further to emission reductions the objectives and trade offs within the policy mix must be explicit

the effects of business models on bank risk before during and after financial crisis evidence from china using chinese data from 2004 to 2016 we investigate the effects of business models on bank risk before during and after financial crisis three main results emerge first insolvency risk and roa

equitable cost benefit analysis of climate change greenhouse gas emissions and vulnerability to climate change show a strong negative correlation this is the moral issue at the heart of the climate problem however little attention has been paid to this in the literature see banuri et al 1996 for an overview the literature on equity issues in climate change is largely confined to the distribution of emissions reduction targets this literature takes the need to reduce greenhouse gas emissions for granted and takes a parametric approach to the required reductions on the other hand the literature that tries to derive how much emissions abatement is desirable largely ducks the equity issue this paper is an attempt to combine the two problems

estimates of the economic effects of sea level rise regional estimates of direct cost dc are commonly used to measure the economic damages of sea level rise such estimates suffer from three limitations i values of threatened endowments are not well known ii loss of endowments does not affect consumer prices and iii international trade is disregarded results in this paper indicate that these limitations can significantly affect economic assessments of sea level rise current uncertainty regarding endowment values as reflected in two alternative data sets for example leads to a 17 percent difference in coastal protec tion a 36 percent difference in the amount of land protected and a 36 percent difference in dc globally also global losses in equivalent variation ev a welfare measure that accounts for price changes are 13 percent higher than dc estimates regional ev losses may be up to 10 percent lower than regional dc however because international trade tends to redistribute losses from regions with relatively high damages to regions with relatively low damages

equitable cost benefit analysis of climate change policies the literature of welfare maximising greenhouse gas emission reduction strategies pays remarkably little attention to equity this paper introduces three ways to consider efficiency and equity simultaneously the first method inspired by kant and rawls maximises net present welfare without international cooperation as if all regions share the fate of the region affected worst by climate change optimal emission abatement varies greatly depending on the spatial and temporal resolution that is the grid at which maximum impact is defined the second method is inspired by varian s no envy emissions are reduced so as to equalise total costs and benefits of climate change over all countries of the world and over all time periods emission reductions are substantial this method approximately preserves the inequities that would occur in a world without climate change the third method uses non linear aggregations of welfare the utilitarian default is linear in a cooperative setting this method cannot distinguish between sources of inequity the higher the aversion to inequity the higher optimal greenhouse gas emission reduction

green revolution and labour demand in rice farming the case of central luzon 1966 90 while the adoption of modern rice varieties mvs increased labour requirements for crop care and other activities it might have induced the adoption of labour saving technologies thus whether the net impact of mv adoption on labour demand is significantly positive is still debated in the green revolution literature using farm level survey data collected in central luzon from 1966 to 1990 this study estimated simultaneously the labour saving technology adoption and the labour demand functions we found among other things that mvs increased labour demand significantly without inducing the widespread adoption of labour saving technologies

can crop purchase programs reduce poverty and improve welfare in rural communities evidence from the food reserve agency in zambia the last decade has seen a resurgence of parastatal crop marketing institutions in sub saharan africa many of which cite improving food security and incomes as key goals however there is limited empirical evidence on the welfare effects of these programs this article considers one such program the zambian food reserve agency fra which purchases maize from smallholder farmers at a pan territorial price that typically exceeds maize market prices in surplus production areas using both fixed effects and an instrumental variables approach combined with correlated random effects we estimate the effects of the fra s maize marketing activities on smallholder farm household welfare results suggest that fra activities have positive direct welfare effects on the small minority of smallholder households that are able to sell to it however the results also suggest negative indirect fra effects as higher levels of fra activity in a district are associated with higher levels of poverty

bank ownership privatization and performance evidence from a transition country abstract this paper combines the static effect of ownership and the dynamic effect of privatization on bank performance in china over 1995 2010 reporting a significantly higher performance by private intermediaries joint stock commercial banks and city commercial banks relative to state owned commercial banks however publicly traded banks subject to multiple monitoring and vetting in capital markets perform better regardless of ownership status the privatization of banks has improved performance with respect to revenue inflow and efficiency gains in the short or long run initial public offerings the positive long run effect is more relevant and significant for banking institutions with minority foreign ownership moreover this paper innovatively estimates interest income efficiency and non interest income efficiency at the same time the results suggest that chinese banks are much more efficient in generating interest income than raising non interest revenue although the latter aspect has improved significantly during the sample period

financial intermediation and delegated monitoring this paper develops a theory of financial intermediation based on minimizing the cost of monitoring information which is useful for resolving incentive problems between borrowers and lenders it presents a characterization of the costs of providing incentives for delegated monitoring by a financial intermediary diversification within an intermediary serves to reduce these costs even in a risk neutral economy the paper presents some more general analysis of the effect of diversification on resolving incentive problems in the environment assumed in the model debt contracts with costly bankruptcy are shown to be optimal the analysis has implications for the portfolio structure and capital structure of intermediaries

the effects of reform on china s bank structure and performance abstract this paper investigates the relationship between market structure and performance in china s banking system from 1985 to 2002 a period when this sector was subject to gradual but notable reform using panel data estimation techniques both the market power and efficient structure hypotheses are tested in addition the model is extended to consider issues such as the impact of bank size ownership and whether the big four banks enjoy a quiet life on average x efficiency declined significantly and most banks were operating below scale efficient levels estimation of the structure performance models lends some support to the relative market power hypothesis in the early period the reforms had little impact on the structure of china s banking sector though the joint stock banks became relatively more x efficient there was no evidence to support the quiet life hypothesis probably because strict interest rate controls prevented the state banks from earning monopoly profits thus the ongoing liberalisation of interest rates should be accompanied by reduced concentration overall to improve competitive structure new policies should be directed at encouraging market entry and increasing the market share of the most efficient banks

what do we learn from the weather the new climate economy literature a rapidly growing body of research applies panel methods to examine how temperature precipitation and windstorms influence economic outcomes these studies focus on changes in weather realizations over time within a given spatial area and demonstrate impacts on agricultural output industrial output labor productivity energy demand health conflict and economic growth among other outcomes by harnessing exogenous variation over time within a given spatial unit these studies help credibly identify i the breadth of channels linking weather and the economy ii heterogeneous treatment effects across different types of locations and iii nonlinear effects of weather variables this paper reviews the new literature with two purposes first we summarize recent work providing a guide to its methodologies datasets and findings second we consider applications of the new literature including insights for the damage function within models that seek to assess the potential economic effects of future climate change jel c51 d72 o13 q51 q54

technologies energy systems and the timing of co2 emissions abatement an overview of economic issues abstract this paper provides an overview of economic issues involved in timing limitations on co2 emissions from energy systems it highlights issues relating to technology availability development and diffusion and the inertia of energy systems as being particularly important the paper sets this in the context of wider uncertainties surrounding the problem and briefly considers other aspects relevant to timing the paper is stimulated by the debate in the usa about optimal abatement paths in particular recent claims that it would be economically preferable to defer such abatement action in favour of measures that support technology development but do not affect emission trends for many years this paper categorizes the various economic issues involved and concludes that for each economic argument that has been advanced to justify deferring emission constraints there are counter vailing economic arguments that could be used in support of rapid near term emissions abatement rational policy lies between these extremes a policy of deferring all emissions abatement exposes economic systems and industries as well as the environment to significantly greater costs and risks than those arising from a more balanced approach furthermore the modelling studies that have been used to justify deferring emissions abatement do so because they embody the economic factors favourable to delay and largely neglect the countervailing issues to the point where their results have little relevance to the overall problem of timing emissions abatement

climate change and the economy in baja california assessment of macroeconomic impacts of the state s climate action plan abstract despite its developing country status mexico ranks 10th worldwide in total greenhouse gas ghg emissions however mexico s vulnerability to climate change impacts is a major motivating factor behind its announced intended contributions at cop21 to cut its baseline emissions by at least 25 in 2030 we analyze the macroeconomic impacts of the climate action plan cap process undertaken in the mexican border state of baja california bc we adapt a state of the art regional macroeconometric model to analyze the bc economy wide impacts of 22 ghg mitigation policy options recommended in the baja california cap the combined effects include an average annual increase of 1680 new jobs or about 0 11 of the average annual employment in the baseline economic forecast and a gross state product gsp increase of 9 85 billion pesos in npv over the 2015 2030 planning horizon although the main objective of ghg mitigation is to reduce atmospheric concentrations and hence future potential damages of these pollutants the stimulus to the bc economy from the implementation of its cap represents a valuable co benefit moreover it is a tangible one that will take place in the near term in contrast to the more long term and more uncertain benefits associated with reducing climate change damages

employment and other macroeconomic benefits of an innovation led climate strategy for the united states abstract climate protection policy and its analysis are pursued in the context of other societal goals among them the maintenance of economic growth and high employment too often however analysis of energy and climate policy does not realistically reflect technological conditions and the dynamics of technological change this tendency unnecessarily associates the decline in energy consumption or carbon emissions with the decline in national economic output or income but there is ample prima facie evidence to the contrary just as in the 19th century when the perceived need to reduce labor inputs as part of the production process spurred labor saving technological progress now the need to reduce energy and pollution costs could spur innovation and diffusion of efficient and clean energy technologies this in turn can increase overall growth in economic productivity energy technology analysts have identified many such existing and near term commercial technologies as well as innovations that can be foreseen beyond the immediate technological horizon which would become widely used if policies were developed to overcome market and institutional barriers this paper presents a macroeconomic analysis for a set of policies that would induce the adoption of more efficient and low carbon technologies and finds that overall employment and economic output could be increased by small amounts while significantly reducing carbon emissions

the role of demandable debt in structuring optimal banking arrangements demandable debt finance by banks warrants explanation because it entails costs of bank suspension liquidation and idle reserve holdings an explanation is developed in which demandable debt provides incentive compatible intermediation where the banker has comparative advantage in allocating investment funds but may act against the interests of uninformed depositors demandable debt attracts funds by giving depositors an option to force liquidation its usefulness in transacting follows from information sharing between monitors and nonmonitors copyright 1991 by american economic association

the economics of changing course implications of adaptability and inertia for optimal climate policy this paper reviews evidence that energy technologies and systems adapt over time to accommodate external pressures that technical innovation and systemic change in the energy sector is largely induced by need and restrained by potentially large transitional costs a simple integrated model of optimal greenhouse gas abatement over time is presented in which the abatement cost depends on both fixed and transitional elements it is shown that the optimal current response and long run prospects differ radically between the classical economic case in which the cost of a given cutback in emissions is fixed exogenously and the adaptive case in which the response is ultimately adaptive but heavily constrained by inertia ie low fixed but high transitional cost if energy systems are indeed to a large degree adaptive the results demonstrate that as compared with the classical non adaptive case long run stabilization of atmospheric co2 may be optimal even with moderate damages from climate change greater near term abatement efforts are justified and the cost of a given delay in response may be several times higher neglect of the issue of induced technical change and other adaptive responses may invalidate the policy implications drawn from most integrated assessment models developed to date

how could emissions trading benefit developing countries abstract this paper aims to show how an emissions trading system could work if some participating entities are allocated an emissions budget or non binding target this will allow them to sell allowances if their actual emissions are less than their budget but will not obligate them to buy allowances if their emissions exceed their budget different rules aiming at ensuring the environmental integrity of such a system are considered parties to the framework convention on climate change may wish to consider building a regime where developing countries are allocated emissions budgets on some provisions of the kyoto protocol and in full respect with the principles of the convention in any case such system would be complementary to the clean development mechanism the potential benefits would be to provide non annex i developing countries with substantial capital inflows and stimulate their economic growth to allow annex i industrialised countries achieving their kyoto commitments at the lowest possible cost and to achieve global participation towards the objective of the convention while reducing the risk of creating tropical hot air by giving some developing countries more allowances than they need under a business as usual scenario

economic growth and global warming a model of multiple equilibria and thresholds abstract we presume a simple endogenous growth model where global warming affects economic growth and analyze the dynamics of the competitive economy and of the social optimum our regulatory instrument is an emission tax rate we demonstrate that for certain values of the emission tax ratio the competitive economy exhibits multiple equilibria and a threshold may exist that separates the domains of attraction for the growth paths there exist paths to high growth rates and low temperature and low growth rates and high temperature for the planner s problem the long run equilibrium is unique unless the damage of global warming is very small

spatial and temporal efficiency in climate policy applications of fund fund is an integrated assessment model of the interactions between climate and economy nine world regions emit greenhouse gases and suffer damages from climate change a number of greenhouse gas emission reduction policies are compared including optimal and cost effective strategies strategies with early and late abatement and strategies with and without international co operation the analyses confirm that co operation matters resulting in substantially lower costs or higher welfare the real commitments of policy targets based on an absolute level e g 1990 emissions are hard to estimate because of the uncertainties in the baseline postponing action conflicts with minimising costs and maximising welfare but so does sharp emission reduction at the short term as proposed in the kyoto protocol

role of agricultural research in poverty reduction lessons from the asian experience abstract the poor spend much of their income on food depend primarily on labour earnings and tend to reside in marginal agricultural areas to reduce poverty agricultural research should aim to ensure adequate food supplies by developing yield increasing technologies to increase labour demand by developing labour using technologies and to develop technologies suitable for marginal areas this article seeks to identify appropriate technologies that agricultural research should generate for poverty reduction the identification is based on a review of the experience of the green revolution in rice production in asia and an assessment of the changing structure of income sources among rural households in the philippines

the impact of learning by doing on the timing and costs of co2 abatement abstract a particular ceiling on atmospheric co 2 concentrations can be maintained through a variety of emission pathways over the past decade there has been considerable debate over the characteristics of a least cost pathway some have suggested that a gradual departure from the emissions baseline will be the most cost effective because it reduces the pressure for premature retirement of the existing capital stock and it provides valuable time to develop low cost low carbon emitting substitutes others counter that a major flaw in analyses that support this line of reasoning is that they ignore learning by doing lbd in this paper we examine the impact of lbd on the timing and costs of emissions abatement with regard to timing we find that including learning by doing does not significantly alter the conclusions of previous studies that treated technology cost as exogenous the analysis supports the earlier conclusion that for a wide range of stabilization ceilings a gradual transition away from the no policy emissions baseline is preferable to one that requires substantial near term reductions we find that the major impact of including learning by doing is on the costs of emission abatement depending upon the sensitivity of costs to cumulative experience lbd can substantially reduce the overall costs of emissions abatement

technological change in economic models of environmental policy a survey this paper provides an overview of the treatment of technological change in economic models of environmental policy numerous economic modeling studies have confirmed the sensitivity of mid and long run climate change mitigation cost and benefit projections to assumptions about technology costs in general technical progress is considered to be a noneconomic exogenous variable in global climate change modeling however there is overwhelming evidence that technological change is not an exogenous variable but to an important degree endogenous induced by needs and pressures hence some environmenteconomy models treat technological change as endogenous responding to socio economic variables three main elements in models of technological innovation are i corporate investment in research and development ii spillovers from r d and iii technology learning especially learning by doing the incorporation of induced technological change in different types of environmental economic models tends to reduce the costs of environmental policy accelerates abatement and may lead to positive spillover and negative leakage

do national level policies to promote low carbon technology deployment pay off for the investor countries abstract national level policies to promote deployment of low carbon technologies have been suggested and used as a means to reduce greenhouse gas emissions in the context of international climate change mitigation the long term benefits of such policies in the context of international climate change mitigation depend on their effects on near term emissions abatement and resultant long term technological change that will reduce abatement costs of achieving global mitigation goals there is also an argument that these policies might foster early mover advantages in international low carbon technology markets we first review the factors that could influence such benefits and use a global integrated assessment model to present an illustrative example to understand the potential magnitude of these benefits we find that reductions in long term abatement costs might not provide sufficient incentives to justify policies to promote the deployment of low carbon technologies in particular the emerging higher risk and currently expensive alternatives we also find that early mover advantages can potentially provide substantial benefits but only if these advantages are both strong and persistent our results suggest a role for international cooperation in low carbon technology deployment to address the existence of free riding opportunities in the context of global climate change mitigation

building an incentive compatible safety net abstract bank safety nets originally proposed as a means of stabilizing financial systems have become an important destabilizing influence government protection of bank debts encourages banks to undertake excessive risk particularly in response to adverse shocks to asset values reforms that would remove the destabilizing moral hazard consequences of government protection are considered both from the perspective of economic desirability and political feasibility requiring banks to maintain a minimal proportion of subordinated debt finance and restricting the means by which government recapitalization of insolvent banks occurs are the central features of promising reforms to the safety net

induced bias of technical change in agriculture the united states and japan 1880 1980 because of extreme differences in factor endowments and price ratios among factors between the united states and japan both countries have experienced sharply different patterns of factor use and productivity growth in agriculture for the past 100 years of modern economic growth in this study the method of testing the hicksian hypothesis of induced innovation was developed using the two level ces production function the model was applied to the historical data of u s and japanese agricultural development for 1880 1980 the results were consistent with the hypothesis that different patterns of technical change in the two countries were induced by differences in the levels and the movements in relative factor prices

what precludes the development of noninterest activities in chinese commercial banks from the perspective of the price of interest activities noninterest activities of chinese commercial banks remain sluggish this article examines the price of interest activities and noninterest activities of chinese commercial banks over 2000 2010 based on ols and 2sls regression we find that the price of interest activities has a significant negative effect on the noninterest activities it appears that controlled interest rate is the main hindrance of the development of noninterest activities and the result is consistent with political view we also find that among state owned commercial banks and nonstate owned ones the relationships of interest activities and noninterest activities are differential the link between the price of interest activities and noninterest activities in state owned commercial banks is stronger than that in nonstate owned commercial banks that is the result of different government intervention degree

a regional dynamic general equilibrium model of alternative climate change strategies outcomes and noncooperative equilibria this study finds that cooperative policies show much higher levels of emissions reductions than do noncooperative strategies that there are substantial differences in the levels of controls in both the cooperative and the noncooperative policies among different countries and that high income countries may be the major losers from cooperation jel h41 q4 q2 q20

income distribution in rice growing villages during the post green revolution periods the philippine case 1985 and 1998 this paper aims to examine changes in household income sources and its impact on household income distribution in the post green revolution periods in 1985 and 1998 in the rural philippines we found that there has been a structural shift of household income away from farm in favor of nonfarm labor income sources this finding indicates that rural development is being led by nonfarm sectors such a shift has resulted in an increase in household income inequality as the distribution of nonfarm income has become less equal over time and was markedly more unequal than that of farm income in 1998

the damage costs of climate change towards a dynamic representation economic assessments of climate change impacts are commonly presented as the effect of a climate change associated with a doubling of the atmospheric concentration of carbon dioxide on the current economy this paper is an attempt to express impact as a function of both climate change and socio economic change with regard to climate change issues discussed are level versus rate of change speed of adaptation speed of restoration and value adjustment and symmetry with regard to socio economic change agriculture migration and the valuation of intangible losses are addressed uncertainty and higher order impacts are treated briefly it is qualitatively argued and quantitatively illustrated that these issues matter a great deal for the damage profile over the next century a damage model based on my best guesses is presented in the appendix

world financial crisis and efficiency of chinese commercial banks the us credit crunch generated substantial turmoil in the global financial markets and directly caused the collapse of several world banking giants nonetheless chinese commercial banks decoupled from the rest of the world achieved remarkable results because of their risk averse nature and banking reform during the past 10 years to improve corporate governance and efficiency the latest reform was focused on ownership transformation via foreign participation and stock listing employing data of 14 listed chinese banks during the period 1999 2008 this paper tests whether ipo was an effective way to enhance banks efficiency using two frontier approaches data envelopment analysis and sfa the results confirm our hypothesis and suggest that restructuring banks into shareholding companies improves both technical efficiency and scale economies this conclusion is further confirmed by the technical inefficiency effects model which found that efficiency rating of listed banks was about 5 per cent higher than their prior ipo level facing tougher economic condition and increased competition banks not only need to broaden income sources cut expenditures but more importantly to strengthen their risk management to become more resistant to a volatile business environment

short term decisions under long term uncertainty the behaviour of future policy makers substantially influences future greenhouse gas emissions uncertainty about the motives of future policy makers may thus strongly influence the climate policy strategies of current policy makers analytical and numerical analyses in this paper confirm this hypothesis if current policy makers want to constrain emissions accumulated over a prolonged period of time and if future policy makers tend with a certain chance to a less ambitious climate policy then current policy makers should intensify their efforts to reduce emissions and the cost of emission reduction in this setting if current policy makers want to meet a cumulative emission contraint in expectation then the preferred policy trajectory does not qualitatively deviate from one suggested by a standard cost effective trajectory if however the constraint is to be met with a certain probability then the importance of early action is enhanced relative to that of postponed action costs substantially increase if current policy makers want to set long term goals without the full cooperation of future policy makers
