exploring policy options for a transition to sustainable heating system diffusion using an agent based simulation change in home heating to more efficient and renewable systems is important for a sound climate policy the present paper aims to identify potential interventions for the uptake of wood pellet heating in norway using an agent based model abm the theoretically based empirically founded agent based simulation demonstrates that financial support i e a stable wood pellet price and technical development i e functional reliability improvement have to be established all at the same time for a successful wood pellet market to start furthermore a soft intervention through persuading households to use environmentally beneficial heating system is not a promising driver for wood pellet diffusion limitations and suggestions for future work are also discussed

co firing coal with wood pellets for u s electricity generation a real options analysis abstract in contrast to eu u s electric utilities are not employing the bioenergy technology of co firing wood pellets with coal this difference in employment patterns is explored within a real options analysis roa for possible u s utilization of wood pellets considering fuel price series from 2009 to 2014 for analysis these series are divided into two sub periods based on different market conditions infancy 2009 2011 and substitution 2012 2014 roa indicates co firing wood pellets with coal is feasible considering adoption during wood pellets infancy under low discount rates and long power plant lifespans a portfolio effect of employing multiple fuels underlies this result however co firing is not currently economically feasible the different adoption decisions are likely a consequence of recent cheap and abundant u s natural gas for co fired wood pellets to be feasible government incentives and or a market increase in natural gas prices appear necessary

higher us crop prices trigger little area expansion so marginal land for biofuel crops is limited abstract by expanding energy biomass production on marginal lands that are not currently used for crops food prices increase and indirect climate change effects can be mitigated studies of the availability of marginal lands for dedicated bioenergy crops have focused on biophysical land traits ignoring the human role in decisions to convert marginal land to bioenergy crops recent history offers insights about farmer willingness to put non crop land into crop production the 2006 09 leap in field crop prices and the attendant 64 gain in typical profitability led to only a 2 increase in crop planted area mostly in the prairie states at this rate a doubling of expected profitability from biomass crops would expand cropland supply by only 3 2 yet targets for cellulosic ethanol production in the us energy independence and security act imply boosting us planted area by 10 or more with perennial biomass crops given landowner reluctance to expand crop area with familiar crops in the short run large scale expansion of the area in dedicated bioenergy crops will likely be difficult and costly to achieve

burning wood pellets for us electricity generation a regime switching analysis abstract applying a regime switching model under the theoretic framework of real options we inspect the optimal timing boundaries for coal and coal mixed wood pellets as two alternative fuels for a power plant in georgia united states results indicate that cofiring wood pellets with coal is generally not a commercially viable option however lower level with wood pellets

intergenerational economic mobility in the united states 1940 to 2000 we estimate trends in intergenerational economic mobility by matching men in the census to synthetic parents in the prior generation we find that mobility increased from 1950 to 1980 but has declined sharply since 1980 while our estimator places greater weight on location effects than the standard intergenerational coefficient the size of the bias appears to be small our preferred results suggest that earnings are regressing to the mean more slowly now than at any time since world war ii causing economic differences between families to become more persistent however current rates of positional mobility appear historically normal

co firing of imported wood pellets an option to efficiently save co2 emissions in europe abstract in this paper the energy and carbon footprints of pellet imports from australia west canada and russia for co firing in europe are investigated their ecologic and economic performances are proven by applying the belgian and uk co firing subsidy systems which require dedicated sustainability evaluations based on the modelling of different subsidy schemes and price scenarios the present paper identifies favourable conditions for the use of biomass co firing in germany and austria which currently do not have dedicated co firing incentives the present paper shows that under present conditions co firing has a narrow financial gap to coal with 3 to 4 cent kwh el and has low co 2 mitigation costs compared to other renewables moreover it is shown that co firing is one of the most cost attractive options to reach the eu 2020 targets for policy makers the support of co firing is found to be very efficient in terms of cost benefit ratio it is proven that the co firing subsidy schemes might direct supply chain decisions towards options with low energy and carbon impacts

learning to carry the cat by the tail firm experience disasters and multinational subsidiary entry and expansion we investigate whether firm experience with discontinuous risks particularly high impact disasters that are episodic and difficult to anticipate moderates the relationship between disasters foreign entry and expansion decisions using a panel data set with 57 500 observations from 106 large european multinational corporations and their subsidiaries operating across 109 countries from 2001 to 2007 we find that although discontinuous risk was negatively related to firm entry and expansion firms that had experience with high impact disasters were more likely to expand in countries experiencing disasters

earthquake fatalities the interaction of nature and political economy to say that the level of fatalities resulting from an earthquake is inversely related to a country s per capita level of income is hardly novel what makes our approach novel is that we relate fatalities to both per capita income and the level of inequality that exists within a country through their joint impact on the likelihood of collective action being taken to mitigate the destructive potential of quakes we first develop a theoretical model which offers an explanation as to why in some environments different segments of society prove incapable of arriving at what all parties perceive to be an agreeable distribution of the burden of the necessary collective action causing the relatively wealthy simply to self insure against the disaster while leaving the relatively poor to its mercy following this we test our theoretical model by evaluating 269 large earthquakes occurring worldwide between 1960 and 2002 taking into account other factors that influence a quake s destructiveness such as its magnitude depth and proximity to population centers using a negative binomial estimation strategy with both random and fixed estimators we find strong evidence of the theoretical model s predictions that is while earthquakes themselves are natural phenomena beyond the reach of humankind our collective inaction with respect to items like the creation and enforcement of building codes failure to retrofit structures and to enact quake sensitive zoning clearly plays a part in determining the actual toll that a given quake takes and it is through these and other examples of collective inaction that limited per capita income and inequality couple together with a given quake s natural destructive power in determining the actual fatalities resulting from a quake

a spatial econometric approach to the economics of site specific nitrogen management in corn production the objective of this study is to determine the potential for using spatial econometric analysis of combine yield monitor data to estimate the site specific crop response functions the specific case study is for site specific nitrogen n application to corn production in argentina spatial structure of the yield data is modeled with landscape variables spatially autoregressive error and groupwise heteroskedasticity results suggest that n response differs by landscape position and that site specific application may be modestly profitable profitability depends on the model specification used with all spatial models consistently indicating profitability whereas the nonspatial models do not

renewable energy policy evaluation using real option model the case of taiwan abstract this study presents a policy benefit evaluation model that integrates cost efficiency curve information on renewable power generation technologies into real options analysis roa methods the proposed model evaluates quantitatively the policy value provided by developing renewable energy re in the face of uncertain fossil fuel prices and re policy related factors the economic intuition underlying the policy making process is elucidated while empirical analysis illustrates the option value embedded in the current development policy in taiwan for wind power in addition to revealing the benefits that re development provides when considering real options analytical results indicate that roa is a highly effective means of quantifying how policy planning uncertainty including managerial flexibility influences re development in addition to assessing the policy value of current re development policy this study also compares policy values in terms of internalized external costs and varying feed in tariff fit simulation results demonstrate that the re development policy with internalized co2 emission costs is appropriate policy planning from sustainability point of view furthermore relationship between varying fit and policy values can be shown quantitatively and appropriate fit level could be determined accordingly

option values to conservation and agricultural price policy application to terrace construction in kenya policy reforms to liberalize agricultural markets in developing countries are likely to influence both the level and the variability of prices while considerable attention has been given to the impact of changes in price level on soil and water conservation there has been relatively little analysis of the role of price variability in conservation decisions we present a model of investment under uncertainty to analyze the effect of both level and variability of prices on the decision to invest in conservation the model is applied to adoption of fanya juu terraces in eastern kenya

valuation of projects for power generation with renewable energy a comparative study based on real regulatory options abstract this comparative study evaluates an investment project on renewable energy based on wind power we have conducted the study in three european union countries denmark finland and portugal we have modelled the main uncertainties that affect this kind of project such as the cost and production of electric power investment costs and consumer price index for each of these countries we have analysed the mechanisms of public support for wind energy we have identified the real options included in the regulatory frameworks of these three countries and assessed how they affect the expanded net present value of the project to this end we have used two different methods of option valuation the monte carlo method and the binomial method we have proved that the obtained results using both methods are quite similar finally we have evaluated the public incentives for wind energy offered in each of these three countries and concluded that in economic terms finland is the country with the strongest support for this kind of energy followed by denmark and in the last place portugal

real options approach to renewable energy investments in mongolia developing nations are seeking alternative energy for electricity and one attractive alternative is renewable energy this research analyzes changing investment environment for renewable energy with real options approach and explores its potential in developing economies through studying the case of mongolia under coal price uncertainty to evaluate comparative attractiveness of either continuing to use coal based infrastructures or switching to renewable energy we formulate social revenue functions for the two environments assuming that renewable energy has lower external costs and coal prices follow geometric brownian motion gbm or geometric mean reverting gmr processes we find the optimal trigger coal prices for switching technologies with some scenarios in electricity price and externality characterize when renewable energy investments become attractive in contrast to conventional wisdom we identify some situations where the value of having more decision opportunities does not exceed that of a now or never decision for switching technologies and welfare losses are incurred the optimal trigger prices are higher in gbm than in gmr and our result raises the possible risks for waiting to switch energy to avoid welfare losses in mongolia the government should increase electricity prices or switch to renewable energy earlier especially when people pay more for the removal of externalities

technology choice under changing peanut policies the effect of marketing quotas and price supports on technology adoption are examined for peanut production in the southeastern united states using a real options model of investment with output price and yield uncertainty the optimal choice of peanut production technology dryland versus irrigated in the southeast is shown to depend on price supports and how they change the manner in which price supports change will have an effect on the choice and rates of abandonment or adoption of production technologies

the role of marriage in the causal pathway from economic conditions early in life to mortality this paper analyzes the interplay between early life conditions and marital status as determinants of adult mortality we use individual data from dutch registers years 1815 2000 combined with business cycle conditions in childhood as indicators of early life conditions the empirical analysis estimates bivariate duration models of marriage and mortality allowing for unobserved heterogeneity results show that conditions around birth and school going ages are important for marriage and mortality men typically enjoy a protective effect of marriage whereas women suffer during childbearing ages however having been born under favorable economic conditions reduces female mortality during childbearing ages

the 1918 influenza pandemic and subsequent health outcomes an analysis of sipp data the fetal origins hypothesis has recently achieved textbook status in medicine see colin d rudolph and abraham m rudolph 2003 david a warrell et al 2003 and is drawing increasing attention from social scientists e g anne case et al 2005 janet currie and enrico moretti 2005 the hypothesis holds that disruptions to fetal nutrition can exert persistent effects on subsequent health from the perspective of a health production function determinants of health may be divided into i post birth health investments e g medicare and ii the initial health endowment the fetalorigins hypothesis emphasizes the importance of the initial health endowment often proxied with birth weight in determining adult health despite growing acceptance of the fetal origins hypothesis by physicians and epidemiologists the physiologic mechanisms by which fetal damage exerts long term effects are relatively poorly understood experimental evidence from animal studies has established that maternal nutrition has a causal effect on subsequent health still researchers have questioned the causality of statistical associations drawn from human populationbased studies of size at birth and subsequent health e g kathleen m rasmussen 2001 a particular concern is whether omitted factors might bias or even account for the positive correlations between measures of early life and adult health recent research has used the 1918 influenza pandemic as a natural experiment for studying the effects of fetal health almond 2003 in contrast to typical influenza strains the 1918 virus disproportionately affected young adults approximately one third of pregnant women contracted the debilitating virus the pandemic arrived without warning and was highly concentrated between october 1918 and january 1919 as a result the long term damage predicted by the fetal origins hypothesis is similarly concentrated approximately two thirds of those in utero during the height of the pandemic would have been born in the first six months of 1919 in order to bias estimates of long term fetal effects post birth health investments would have to behave in the same abrupt manner as the pandemic using decennial census data for 1960 1980 almond 2003 found that cohorts in utero during the height of the pandemic displayed reduced educational attainment increased rates of disability lower income and lower socioeconomic status however the absence of specific health outcomes in the census precludes identification of physiologic pathways and therefore limits the relevance of the findings for physicians and epidemiologists using data from the survey of income and program participation sipp this study finds that cohorts in utero during the pandemic exhibit impaired health outcomes relative to cohorts born a few months earlier or later that these patterns are manifest 65 80 years after the pandemic suggests that changes to fetal health can have life long effects

economic status and health in childhood the origins of the gradient the well known positive association between health and income in adulthood has antecedents in childhood not only is children s health positively related to household income but the relationship between household income and children s health becomes more pronounced as children age part of the relationship can be explained by the arrival and impact of chronic conditions children from lower income households with chronic conditions have worse health than do those from higher income households the adverse health effects of lower income accumulate over children s lives part of the intergenerational transmission of socioeconomic status may work through the impact of parents income on children s health

biodiesel investment in a disruptive tax credit policy environment abstract an investigation of poisson type policy jumps on biodiesel investment considers the theory of investment under uncertainty the analysis studies the probability of implementing a policy if it is not in effect and the probability of withdrawal if it is in effect an application models the policy switching regime of the discontinuous u s federal tax credit of 1 00 per gallon on biodiesel results support that time inconsistent government policies do lead to market uncertainty the analysis reveals a pronounced negative impact on decisions to invest in a biodiesel refinery results do indicate a consistent policy switching regime may not be that disruptive to the emerging biodiesel industry it is policy uncertainty that drives the option pricing thresholds and a consistent policy switching does not increase the uncertainty

firm specific assets and the link between exchange rates and foreign direct investment foreign direct investment fdi theory and empirical studies have generated mixed support for a link between exchange rates and fdi this paper argues that exchange rate movements may affect acquisition fdi because acquisitions involve firm specific assets which can generate returns in currencies other than that used for purchase using data on japanese acquisitions in the united states across three digit sic industries from 1975 to 1992 maximum likelihood estimates from discrete dependent variable models support the hypothesis that real dollar depreciations make japanese acquisitions more likely in u s industries particularly those which more likely have firm specific assets copyright 1997 by american economic association

the open society assesses its enemies shocks disasters and terrorist attacks abstract this paper conducts a systematic investigation of the incidence and economic costs of terrorist attacks at the country level we use newly assembled datasets on terrorist attacks natural disasters and currency crises to answer three different questions what are the determinants of terrorism is there an output cost following a terrorist attack and is that cost larger or smaller in the case of democracies we find that rich countries are the most prone to suffer attacks while democracies are if anything less vulnerable than other countries the cost to output of a terrorist attack is quantitatively small and closely associated with the occurrence of an event rather than the number of casualties finally we find robust evidence that a terrorist attack imposes a lower output cost the more democratic a country is

policy incentives for switchgrass production using valuation of non market ecosystem services abstract this study presents a linear profit model with combined economic and environmental factors for a switchgrass for biofuels agricultural system in the southeastern u s the objectives are to establish conversion to switchgrass thresholds for various market prices and identify policy incentives that would ensure economic profit while also maximizing environmental benefits carbon sequestration displacement of fossil fuels and minimizing negative impacts global warming potential nitrate loss weighting factors are chosen to represent incentives and penalties by assigning value to the impacts with no other incentives switchgrass market prices of at least 51 and 58 dton would be needed in order to make a profitable switch from corn conservation reserve program crp lands and cotton respectively at a mid range offering of 50 dton feasible carbon credit prices of 3 8 23 per metric tonne co 2 e would incentivize conversion from corn crp or cotton respectively similarly a water quality penalty of 0 20 3 2 per kilogram no 3 n leached would incentivize the same conversions with resultant watershed improvement at a lower price of 30 dton switchgrass incentives based on valuation of ecosystem services begin to exceed feasible ranges of these valuations

application of the modified tobin s q to an uncertain energy saving project with the real options concept abstract this paper is to develop a modified tobin s q evaluation method which successfully combines the evaluation criteria of the traditional tobin s q and the real options this study provides flexible thinking for decision making criteria that is it clearly provides decision makers with a reference in choosing enter or exit strategies such as quantitative indicators references the proposed model introduces two variables stochastic process in continuous time and explores the impact of the occurrence of unexpected events on the project value so that it can more authentically response to the project value the studied issue deals with the firms that have not established energy saving equipment yet it attempts to figure out the optimal timing to adopt an energy saving investment project when it is beneficial and the optimal timing to terminate it when the continuous operation of that business is unprofitable the future discounted benefit cost ratio q follows the geometric brownian motion with the poisson jump process and the replacement of investment equipment except for the evaluation of energy saving equipment investment project the proposed model can be applied to other related project evaluation issues such as energy saving co 2 emission reduction or general investment projects

capital investment strategies under uncertain regulation this article presents a positive model of investment choices by regulated firms that offers rational explanations for electric utilities recent behavior of delaying investment and choosing smaller shorter lead time technologies the model assumes thatfirms capital investments require long lead times during which the value of the completed project is uncertain firms anticipate regulatory profit and loss restrictions but expectations about the value of a completed project change over time firms decisions are modelled using an option pricing approach that incorporates the value of flexibility to delay or abandon projects the article shows why rational firms invest in smaller shorter lead time plants or delay investment when faced with uncertain and asymmetric profit and loss restrictions it also looks at decisions to abandon partially completed plants and shows that the static result that a higher cost allowance on abandoned projects increases the incentive for investment is not generally true in a dynamic model

an entry and exit model on the energy saving investment strategy with real options this paper presents an improved decision model based on the real options approach presented by ansar and sparks 2009 for the firms that have not yet established energy saving equipment under the entry and exit strategies furthermore the proposed model takes account of the inevitable equipment renewal and the occurrence of unexpected events under the poisson jump process the timing for terminating an investment when continuous operations of that business are unprofitable is also explored to realize the optimal timing of implementing the energy saving strategy the future discounted benefit b follows the geometric brownian motion with the poisson jump process and the replacement of investment equipment a numerical analysis is followed by a sensitivity study of various parameters to better realize their impacts on the entry and exit thresholds the results show that for the jump case the higher probability of occurrence of unfavorable events will result in a higher entry threshold and lower exit threshold investors are forced to request higher benefit thresholds to cover the higher probability of losses brought by unfavorable events

applying real options analysis to assess cleaner energy development strategies abstract the energy industry accounts for the largest portion of co 2 emissions is facing the issue of compliance with the national clean energy policy the methodology for evaluating the energy mix policy is crucial because of the characteristics of lead time embedded with the power generation facilities investment and the uncertainty of future electricity demand in this paper a modified binomial model based on sequential compound options which may account for the lead time and uncertainty as a whole is established and a numerical example on evaluating the optional strategies and the strategic value of the cleaner energy policy is also presented it is found that the optimal decision at some nodes in the binomial tree is path dependent which is different from the standard sequential compound option model with lead time or time lag concept the proposed modified binomial sequential compound real options model can be generalized and extensively applied to solve the general decision problems that deal with the long lead time of many government policies as well as capital intensive investments

natural disasters and foreign direct investment the world s population has witnessed the concurrence of two powerful global trends an unprecedented growth in foreign direct investment fdi and an increase in natural disasters since investment decisions are based on an evaluation of expected risks and returns we consider whether fdi decisions are influenced by natural disasters we do so by considering the relation between fdi in 94 countries between 1984 and 2004 and the number of disasters striking those countries across a variety of empirical tests that control for two way fixed effects we find natural disasters to be negatively and statistically significantly associated with a country s fdi

estimating maximum land use change potential from a regional biofuel industry abstract the maximum amount of land for growing switchgrass for ethanol is estimated for a region in the southeastern u s breakeven capacities are calculated for land in row crops hay pasture and marginal land characteristics of land categories inform potential land use change impacts as well as switchgrass profitability variable yields within and across land categories are translated into distributions of switchgrass net revenue breakeven curves are generated for a range of switchgrass prices these curves provide upper bounds for further analysis of actual switchgrass adoption in context of broader economic forces and possible policy mechanisms to minimize environmental impacts a farm gate price of 55 mg 1 is estimated for half of marginal and pasturelands to break even with switchgrass at this price only 20 of land in hay and a small fraction of row crop hectares break even half of hay and row crops hectares break even at approximately 90 mg 1 and 100 mg 1 respectively at 60 mg 1 sufficient land area can profitably produce switchgrass for ethanol to displace approximately 10 of gasoline consumed in georgia north carolina and south carolina however this price only indicates breakeven capacity implying that higher prices may be necessary to realize 10 displacement

the macroeconomic consequences of disasters abstract natural disasters have a statistically observable adverse impact on the macro economy in the short run and costlier events lead to more pronounced slowdowns in production yet interestingly developing countries and smaller economies face much larger output declines following a disaster of similar relative magnitude than do developed countries or bigger economies a close study of the determinants of these adverse macroeconomic output costs reveals several interesting patterns countries with a higher literacy rate better institutions higher per capita income higher degree of openness to trade and higher levels of government spending are better able to withstand the initial disaster shock and prevent further spillovers into the macro economy these all suggest an increased ability to mobilize resources for reconstruction financial conditions also seem to be of importance countries with more foreign exchange reserves and higher levels of domestic credit but with less open capital accounts appear more robust and better able to endure natural disasters with less adverse spillover into domestic production

technology adoption decisions under irreversibility and uncertainty an ex ante appproach empirical results demonstrate that uncertainty about costs and requirements for environmental compliance is an important determinant of dairy producers investment behavior ex ante forecasting of how uncertainty and irreversibility are likely to affect producers responsiveness to agricultural technologies has implications for the design of environmental policies simulation modeling methods are described the empirical analysis focuses on texas producers propensity to adopt free stall dairy housing free stall investments offer advantages for both productivity augmentation and pollution abatement yet uncertainty and irreversibility are obstacles to adoption implications of this ex ante paradigm for policy design and implementation are discussed

technical change and irreversible investment under risk abstract a stochastic dynamic model was constructed to analyze investment decisions of an individual farmer under risk in the presence of irreversibilities embedded technical change and indivisible capital an analytical solution was obtained and its local behavior studied by numerical methods optimal investment is obtained by regulating the difference between the desired and actual capital stocks between two barriers that define an inaction interval while the desired capital drifts between the barriers no action is taken if the desired capital touches the upper barrier the farmer invests pushing the average efficiency of the actual capital stock up this in turn raises the desired capital even higher and contracts the inaction interval if these effects are strong enough the farmer will invest again until the potential gains of the technological package are exhausted if the desired capital falls enough the farmer disinvests pushing down the average productivity and expanding the inaction interval disinvestment continues until it stops either because the inaction interval becomes so wide that it is no longer optimal to disinvest or because the actual capital stock is so small that it is no longer profitable to produce

bt cotton in india field trial results and economic projections abstract the performance of bt cotton in india is analyzed on the basis of field trial data from 2001 the amounts of pesticides applied during the trials were reduced to one third of what was used in conventional cotton while under severe pest pressure yield gains were 80 productivity effects are modeled econometrically with a damage control specification the first approval for the commercial cultivation of bt hybrids was given in 2002 by 2005 the technology is expected to cover one quarter of total indian cotton area medium term projections show sizeable welfare gains for the overall economy with farmers being the main beneficiaries

the macroeconomic impacts of natural disasters the case of floods we use panel vector autoregression models to trace the dynamic response of output growth to flood shocks using new data on large flood events in 135 countries between 1985 and 2008 flood shocks tend to have a positive and significant average impact on per capita gdp growth however this effect is limited to developing countries and to moderate floods the positive impact of floods is larger and more significant in the agricultural sector while floods seem to have a direct effect on agricultural growth rates in developing countries their effect on nonagricultural growth rates is mainly indirect jel o11 q54

switching to perennial energy crops under uncertainty and costly reversibility we study a farmer s decision to convert traditional cropland into land for growing dedicated energy crops taking into account sunk conversion costs and uncertainties in crop returns the optimal decision rules differ significantly from the expected net present value rule which ignores uncertainties and from real options models that allow only one way conversion into energy crops these models also predict drastically different patterns of land conversions into and out of energy crops over time using corn soybean rotation and switchgrass as examples we show that the model predictions are sensitive to assumptions about stochastic processes of the returns government policies might have unintended consequences subsidizing conversion costs into switchgrass may not much affect proportions of land in switchgrass in the long run

when the carrot goes bad the effect of solar rebate uncertainty abstract although meant to encourage investment in solar photovoltaic pv systems some incentive policies may themselves become a barrier in instances where policy related uncertainty is present as potential solar adopters delay their investment until uncertainty is resolved this study utilizes a quasi experimental setting to quantify the effect of solar policy uncertainty focusing on the california solar initiative s residential rebate program i exploit the temporary exhaustion of funds within one of the utility territories as an exogenous source of increased uncertainty and estimate that it leads to a 67 drop in rebate applications in an average zip code week there is considerable heterogeneity in this effect depending on household income and pv system size among households that are least likely to invest in pv without a rebate incentive program participation drops by up to 69 this suggests potentially significant loss in program effectiveness due to lower pv adoption and underscores the importance of accounting for uncertainty in policy evaluations

heat or power how to increase the use of energy wood at the lowest cost abstract we compute the optimal subsidy level for fuelwood consumption that makes it possible to achieve the french biomass energy consumption target for this purpose we model the competition and trade offs between the consumption of fuelwood for heat fw h and the consumption of fuelwood for electricity fw e to do so we couple a forest sector model with an electricity simulation model and we test different scenarios combining fw h and fw e that account for contrasting potential increases in the carbon price and the potential reduction in the number of nuclear plants we assess the implications of these scenarios on 1 the budgetary costs for the government 2 industrial wood producers profits 3 cost savings in the power sector for the different scenarios tested and 4 the carbon balance we show that the scenario with the highest carbon price and the lowest number of nuclear plants is the least expensive from a budgetary perspective indeed when associated with a high carbon price co firing may increase fw e demand with a lower subsidy level which makes it possible to reduce the cost of reaching the target however in this case fw e crowds out part of fw h which may cause political and economic issues from a carbon balance perspective an fw h only scenario performs better than any other scenario that combines fw h and fw e due to the relatively low emissions factors of alternative technologies for electricity generation and in particular nuclear energy

biofuel economics in a setting of multiple objectives unintended consequences this paper examines biofuels from an economic perspective and evaluates the merits of promoting biofuel production in the context of the policies multiple objectives life cycle implications pecuniary externalities and other unintended consequences the policy goals most often cited are to reduce fossil fuel use and to lower greenhouse gas emissions but the presence of multiple objectives and various indirect effects complicates normative evaluation to address some of these complicating factors we look at a several combinations of policy alternatives that achieve the same set of incremental gains along the two primary targeted policy dimensions making it possible to compare the costs and cost effectiveness of each combination of policies for example when this approach is applied to u s produced biofuels they are found to be 14 31 times as costly as alternatives like raising the gas tax or promoting energy efficiency improvements the analysis also finds the scale of the potential contributions of biofuels to be extremely small in both the u s and eu mandated u s corn ethanol production for 2025 reduces u s petroleum input use by 1 75 and would have negligible net effects on co2 emissions and although eu imports of brazilian ethanol may look better given the high costs of other alternatives this option is equivalent at most to a 1 20 reduction in eu gasoline consumption

the twin instrument fertility and human capital investment twin births are often used as an instrument to address selection of women into fertility however recent work shows selection of women into twin birth such that while ols estimates tend to be downward biased twin iv estimates will tend to be upward biased this is pertinent given the emerging consensus that fertility has limited impacts on women s labour supply or on investments in children using data for developing countries and the united states to estimate the trade off between fertility and children s human capital we demonstrate the nature and size of the bias in the twin iv estimator and estimate bounds on the true parameter

economic development and the impacts of natural disasters abstract we use disaster impact data over time to examine the degree to which the human and economic losses from natural disasters are reduced as economies develop we find that countries with higher income higher educational attainment greater openness more complete financial systems and smaller government experience fewer losses

how corruption influences foreign direct investment a panel data study abstract this article analyzes the sign and development of the effect of corruption on foreign direct investment fdi economic theory distinguishes grabbing hand corruption from helping hand corruption the former suggests a negative impact of corruption on fdi the latter one a positive effect empirically we apply a data set of 21 home and 59 developed and less developed host countries covering between 1983 and 1999 to investigate the corruption impact we employ a panel data model that particularly refers to the knowledge capital model of multinational activity we find a negative relationship between corruption and fdi this in turn suggests that the helping hand effects of corruption are outweighed by the grabbing hand effects further we observe that corruption is an important impediment of fdi in developed economies but not in less developed ones finally we demonstrate that the importance of corruption has decreased over the years

real option valuation in renewable energy literature research focus trends and design abstract in light of intensive development of the renewable energy re sector a growing number of academic papers address the complexity of re investment planning and valuation to take account of the high risk profile and irreversibility of re investments researchers have resorted to sophisticated real options ro approaches that enable flexibility to be incorporated into project design in the face of an uncertain environment the variety of different frameworks and models adopted as well as a lack of aggregated analysis of the field suggest a need for a critical review of ro methodology and design in re assessment this study describes the research focus trends and design found in contemporary academic literature devoted to re valuation with a ro approach particular attention is given to ro in project and policy design the results give a comprehensive picture of existing research on the topic thus providing researchers with a solid foundation for further study and indications of directions for future development furthermore the findings provide policymakers and project planners with valuable insights into key aspects of re project and policy design

international investment location decisions abstract in international location tournaments governments compete for foreign investment with tax and other short run incentives such tournaments can be won if agglomeration economies are sufficiently powerful to overcome investors desire to spread investments as a hedge against risk we focus on manufacturing investments by u s multinationals in the 1980s our econometric results suggest that agglomeration economies are indeed the dominant influence on investor calculations paradoxically short run incentives have limited apparent impact on location choice we conclude that high cost tournament play is unnecessary for countries with good infrastructure development specialized input suppliers and an expanding domestic market

portuguese pellets market analysis of the production and utilization constrains abstract as opposite in portugal the wood pellets market is booming in europe in this work possible reasons for this market behavior are foreseen according to the key indicators of biomass availability costs and legal framework two major constrains are found in the portuguese pellets market the first one is the lack of an internal consumption being the market based on exportations the second one is the shortage of raw material mainly due to the competition with the biomass power plants therefore the combination of the biomass power plants with pellet production plants seems to be the best option for the pellets production in the actual portuguese scenario the main constrains for pellets market has been to convince small scale customers that pellets are a good alternative fuel mainly due to the investment needed and the strong competition with natural gas besides some benefits in the acquisition of new equipment for renewable energy they are insufficient to cover the huge discrepancy of the investment in pellets heating however pellets are already economic interesting for large utilizations in order cover a large amount of households additional public support is needed to cover the supplementary costs of the pellets heating systems

global foreign direct investment flows the role of governance infrastructure abstract it is widely argued that a country s economic performance over time is determined to a great extent by its political institutional and legal environment we refer to these institutions and policies as the governance infrastructure of a country we utilize newly developed indices to examine the effects of governance infrastructure on both foreign direct investment fdi inflows and outflows for a broad sample of developed and developing countries over 1995 97 in addition we examine the role of other forms of infrastructure including human capital and the environment the results clearly indicate that governance infrastructure is an important determinant of both fdi inflows and outflows investments in governance infrastructure not only attract capital but also create the conditions under which domestic multinational corporations emerge and invest abroad it would appear that investments in governance infrastructure are subject to diminishing returns so that the benefits in terms of inflows are most pronounced for smaller and developing economies

opportunities and barriers for international bioenergy trade recently the international trade of various bioenergy commodities has grown rapidly yet this growth is also hampered by some barriers the aim of this paper is to obtain an overview of what market actors currently perceive as major opportunities and barriers for the development of international bioenergy trade the work focuses on three bioenergy commodities bioethanol biodiesel and wood pellets data were collected through an internet based questionnaire the majority of the 141 respondents had an industrial background geographically two thirds were from mainly western europe with other minor contributions from all other continents results show that import tariffs and the implementation of sustainability certification systems are perceived as potentially major barriers for the trade of bioethanol and biodiesel while logistics are seen mainly as an obstacle for wood pellets development of technical standards was deemed more as an opportunity than a barrier for all commodities most important drivers were high fossil fuel prices and climate change mitigation policies concluding to overcome some of the barriers specific actions will be required by market parties and policy makers import tariffs for biofuels could be reduced or abolished linked to multinational trade agreements and harmonization including provisions on technical standards and sustainability requirements
