provision of electricity to african households the importance of democracy and institutional quality how can differences in per capita household electricity consumption across african countries be understood based on theories that highlight the importance of democracy and institutional quality for provision of public goods the aim of the paper is to analyse the degree to which the level of per capita household electricity consumption in african countries can be attributed to the countries democratic status and their institutional quality we rely on regression analysis employing a pooled data set for 44 african countries over the time period 1996 2009 the analysis shows that democracy and institutional quality both have significant positive effects on per capita household consumption of electricity our results have implications for how energy sector reforms are promoted in developing countries at a more general level they illustrate that institution building policy efforts are relevant also in areas where contemporary debates have tended to primarily centre on economic development financial prerequisites and ownership issues

renewable energy in pacific small island developing states the role of international aid and the enabling environment from donor s perspectives abstract dependency on fossil fuels is an issue for numerous countries and in particular it is an acutely challenging problem for pacific small island developing states for the utilization of renewable energy in pacific small island developing states donor agencies and international organizations play major roles in funding this study introduces the nature of the past renewable energy projects in pacific small island developing states and in the process clarifies the contribution of international aid to renewable energy deployment thereafter the paper identifies the most important factors related to enhancing an enabling environment for the introduction of renewable energy in pacific small island developing states and the relative importance of these factors with a special focus on donors perspectives the paper clarifies that approximately 1 5 billion usd 2011 was received by pacific small island developing states over the 44 years from 1970 to 2014 as funding for renewable energy projects that included funding for hardware and the amount of aid allocated for renewable energy in the region greatly varies between countries the paper also identifies the important factors that can enhance an enabling environment for the introduction of renewable energy and the relative importance of these factors some of the highlighted implications that can be made from the findings of the research are 1 high renewable energy targets need to be supported by well structured action plans 2 there is a need for an effective regulatory body responsible for renewable energy and 3 the financial aspects of utilities are of higher importance than technological aspects of utilities

the effects of devaluation on the trade balance a critical view and re examination of mile s new results abstract in a often cited article miles 1979 claims to have shown empirically the validity of the global monetarist proposition that devaluations do not affect the balance of trade this paper first uses mile s own framework of analysis to reveal serious deficiencies in his methodology and tests that cast doubt on the validity of his results in a respecified trade balance equation we show that devaluations do affect the trade balance in the traditionally predicted direction the pivotal difference between the two specifications arises from our inclusion of relative price effects and longer lag structure for the exchange rate variable

monetary shocks the exchange rate and the trade balance abstract this paper investigates the response of the exchange rate and the trade balance to monetary policy innovations for the us economy during the period 1973 01 1993 12 the empirical findings indicate that contractionary monetary policy shocks lead to transitory appreciations of the real and the nominal exchange rate exchange rate appreciations that are caused by a temporary contractionary shock to monetary policy are correlated with a short lived improvement in the trade balance which is then followed by a deterioration giving support to the j curve hypothesis

devaluation and the j curve some evidence from ldcs within the international trade literature it is not uncommon to find arguments about whether devaluation will improve the trade balance it is argued that the flows of goods respond only with time lags to changes in the exchange rate the j curve terrn is used to describe the movement over time of the trade balance it may deteriorate at first and improvement may come later this paper presents a method by which one could detect the existence of the j curve the method is applied to four developing countries the empirical evidence supports the pattern of movemnent described by the j curve a major policy option for a country facing a persistent balance of payments deficit is said to be devaluation of its currency within the international trade literature it is not uncommon to find arguments about whether devaluation will improve the trade balance or the balance of payments for example proponents of the elasticities approach describe the necessary and sufficient conditions for an improvement in the trade balance in terms of elasticities of demand and supply referred to as the marshall lerner condition while there is abundant empirical evidence to suggest that these conditions are indeed met at least for industrial countries there have been circumstances under which 2 devaluation has not been successful for example one might wonder why the u s trade balance deteriorated so much in 1972 despite the devaluation of the dollar in 1971 this unfavorable effect of devaluation on the trade balance is termed the j curve phenomenon received for publication august 23 1984 revision accepted for publication november 26 1984 the university of wisconsin milwaukee i would like to thank two anonymous referees for their valuable comments on the initial draft of this paper 1 proponents of the absorption approach e g alexander 1952 describe how devaluation may change the terms of trade increase production and switch expenditures from foreign to domestic goods thus improving the trade balance international monetarists argue that devaluation reduces the real value of cash balances and or changes the relative price of traded and nontraded goods thus improving both the trade balance and the balance of payments 2 for an cstimate of the elasticities see houthakker and magee 1969 and warner and kreinin 1983 the former study provides the elasticities estimates under fixed exchange rates and the latter under floating rates this content downloaded from 157 55 39 17 on wed 31 aug 2016 04 39 37 utc all use subject to http about jstor org terms

energy policy aid and the development of renewable energy resources in small island developing states abstract small island developing states sids have established ambitious renewable energy targets the promotion of renewable energy has been motivated by several factors a desire to lessen dependence on fossil fuels to attract development assistance in the energy sector and to strengthen the position of sids in climate change negotiations here we explore the interplay between the role of aid and energy policy in the development of renewable energy resources in sids we find that the importance of development assistance has implications for the sustainability of renewable energy development given that funding is not always accompanied by necessary energy policy reforms we also identify energy efficiency and access to modern energy services as having received insufficient attention in the establishment and structure of renewable energy targets in sids and argue that this is problematic due to the strong economic case for such investments

the effect of uncertainty on the demand for medical care health capital and wealth we analyze the effect of the uncertainty of the incidence of illness on the demand for medical care and on the accumulation of health capital and wealth over the retirement years we use a simplified version of a dynamic grossman household production model to characterize patterns of an individual s precautionary behavior elderly individuals respond to uncertainty by smoothing their expected utility over time by making specific patterns of purchases of medical care and consumption we examine these patterns for individuals with different degrees of risk aversion

the j curve in the emerging economies of eastern europe devaluation or depreciation of a currency worsens the trade balance before improving it resulting in a j curve pattern a new definition of the hypothesis implies a short run deterioration combined with the long run improvement by using monthly data over the january 1990 june 2005 period from 11 east european emerging economies most of which are the new european union eu members or the eu candidate countries this article uses the bounds testing approach to cointegration and error correction modelling and finds empirical support for the j curve hypothesis in three countries of bulgaria croatia and russia the results have important implications for policymakers involved in economics in terms of using exchange rate policy as a policy device to achieve real convergence toward eu standards

opening up and transition success and problems financing and reforms of the electric power sector in latin america and the caribbean abstract financing problems triggered the wave of electric power sector reforms in latin america and the caribbean the reforms in turn have changed the functioning of financing in the power sector financial institutions have continually adapted their instruments existing sources of capital have stepped up investing in the sector and new financial sources have emerged this paper reviews the evolution of financing and its interplay with legal and structural reforms and property rights changes in the electric power sector of latin america and the caribbean it classifies sector development in the region by reform strategies and their consequences for financing finally it conducts an assessment using criteria such as sector financing sector efficiency general economic efficiency economic development objectives and the environment it finds that the different reform and financing strategies have distinctive impacts on the sustainable development of the sector through their impacts on the choice of generating technology and fuel on the contribution of cogeneration and renewable energy sources on participation of national capital and national human capital formation and on rational use of energy

determinants of international trade flows this paper models and estimates import demand and demand for export functions for 19 industrial countries although primary emphasis is placed on the period of generalized floating exchange rates 1972 through 1980 estimates are also provided for the fixed exchange rate years 1957 1970 thus making possible a comparison between the two eras aside from the conventional income and price variables the paper assesses the effect of variations in the exchange rate and in the expected exchange rate on real trade flows additionally it estimates an unrestricted lag structure of the effect of price and exchange rate variations on imports

an asymmetric analysis of the j curve effect in the commodity trade between china and the us this paper follows a non linear ardl error correction approach to examine the presence of the j curve in the commodity level trade between the united states and china the analysis disaggregates the us china trade flows by commodities and separately examines the trade balance responses of 97 commodities to the changes in the real yuan us exchange rates the analysis at the commodity level alleviates potential aggregation bias that is present in earlier studies offering little evidence for long run asymmetric effects of exchange rate on the china us trade balance we find strong support for short run asymmetric effects in the case of two third of the commodities whereas significant long run asymmetric effects are present in the case of one third of the commodities including those commodities which command large shares in the china us trade

correction note on the demand for health with uncertainty and insurance abstract this paper proves the non existence of an optimal solution under the liljas liljas b 1998 the demand for health with uncertainty and insurance j health econ 17 153 170 type of insurance the reason for the non existence is that the insurance induces the individual to increase his time input relative to medical expenditure in the household production of health investment hence it distorts the balance of inputs in the production of health investment moreover it also distorts the household production for consumption goods through time constraints therefore this paper proposes an alternative insurance that covers the time loss due to illness and has an optimal solution

uncertainty and health care spending by the poor the health capital model revisited this short theoretical paper examines health care utilization by the poor in the context of grossman s 1972 health capital model earlier work has shown that uncertainty can reduce the attractiveness to the poor of health capital investments this paper demonstrates that uncertainty can also have precisely the opposite effect that is while there may be cases in which it is excessively risky for the poor to invest in their health there may also be cases in which the poor can ill afford the risks that arise from not making timely investments in their health

renewable energy investment by the world bank world bank group lending for renewable energy accelerated in the 1990s and resulted in 17 approved projects with 700 million in bank loans and 230 million in grants by the global environment facility the bank s 1999 energy sector strategy fuel for thought charted new directions for renewable energy investment the present paper considers the implementation challenges of fuel for thought strategies and the opportunities for carrying them out the paper distinguishes between agendas in the energy and rural development sectors and reviews limitations to implementing these agendas lessons from projects are just emerging but suggest ve areas of support for renewable energy by the bank in the future renewable energy nancing electric power policy frameworks rural energy enterprises regulated rural energy concessions and domestic technology manufacturing interviews with the private sector suggest additional forms of support assist with business plans nance pre feasibility studies reduce commercial risks support joint ventures build market volume and stability and pilot and test innovative business models the e ectiveness of the bank in following through on its ambitious agenda fundamentally rests on the willingness and commitment of developing countries to pursue these strategies and the degree to which renewable energy applications are seen to serve countries development priorities 2001 elsevier science ltd all rights reserved

renewable energy support mechanisms in the gulf cooperation council states analyzing the feasibility of feed in tariffs and auction mechanisms renewable energy will be a crucial ingredient in the transition to a more sustainable future the renewable energy sector requires a variety of financial support mechanisms in order to further consolidate and expand currently the most prominent renewable energy support mechanisms are feed in tariffs and renewable energy auctions although these mechanisms have been used and analyzed extensively in western countries and more recently economies in transition they have rarely been examined in the arab gulf region yet particularly the gulf cooperation council gcc states have undertaken important steps towards renewable energy adoption which could be greatly facilitated with the use of financial support mechanisms this paper analyzes the feasibility of feed in tariffs and renewable energy auctions adoption in gcc based on an extensive meta analysis of the literature on these two mechanisms in both developed and developing countries the paper identifies a set of conditions necessary for success and evaluates the presence of favorable these conditions in the gcc context our findings reveal that while conditions that would ensure political feasibility are largely absent for both types of mechanisms auctions could be a more successful strategy at the moment

human development at risk economic growth with pollution induced health shocks risks to human health stemming from polluted air water and soil are substantial especially in the rapidly growing economies the present paper develops a theoretical framework to study an endogenously growing economy which is subject to pollution induced health shocks with the health status being an argument of the welfare function pollution arising as a negative externality from production adversely and randomly affects the regeneration ability of a human body leading to a decline in the overall health status of the population we include two types of uncertainty surrounding the health status continuous small scale fluctuations driven by the wiener process and large scale shocks or epidemics driven by the poisson process we derive closed form analytical solutions for the optimal abatement policy and the growth rate of consumption devoting a constant fraction of output to emissions abatement delivers the first best allocation this fraction is an increasing function of total factor productivity polluting intensity of production and damage intensity of both continuous and jump type shocks a higher frequency of jumps also calls for more vigorous abatement policies by contrast the optimal growth rate of the economy is decreasing in the frequency and intensity of shocks and in the polluting intensity of output the efficiency of abatement technology has in general an ambiguous bearing on both the growth rate and on the abatement share due to the opposing forces of the direct and indirect effects

staggered price setting translog preferences and endogenous persistence abstract this paper generates persistent real effects of a monetary disturbance in the context of staggered price setters the model combines two related and reinforcing features a translog demand structure and a particular input output production structure these features offer a rationale why a firm when computing its own optimal contract price is influenced by the prices set in other overlapping contracts practically the two features interact in a positive manner and provide a way to generate significant endogenous persistence

anticipated versus unanticipated terms of trade shocks and the j curve phenomenon abstract using a dynamic stochastic general equilibrium dsge model we examine the impact of anticipated and unanticipated terms of trade tot shocks on aggregate output inflation and the trade balance tb this allows us to offer an alternative explanation of the j curve phenomenon we find that an unanticipated tot shock increases real output as well as inflation but the j curve phenomenon may not exist under a certain condition however under the same condition an anticipated tot shock leads to the j curve effect we find that our main result concerning the j curve phenomenon continues to hold even if the assumption of rational expectations about the tot is relaxed further analysis reveals that the presence of a cost channel of monetary policy increases the intensity of the j curve effect assuming plausible parameter values while using a more general model calibration results support our theoretical predictions

determinants of international trade flows the case of developing countries abstract the question of magnitude and the time path of the trade flows to changes in the exchange rates and to changes in the price level is of emitent practical importance to assess the above proposition a distributed lag structure is imposed on the relative prices and on the effective exchange rate as the determinants of trade flows then import and export demand functions are estimated for a sample of developing countries using the almon procedure the empirical findings appeared to sustain orcutt s early conjecture that trade flows adjust differently to different price stimuli more precisely it was found that imports and exports reactions were quicker and the total response time was shorter when an exchange rate rather than relative prices caused a change in international prices

renewable energy sector development in the caribbean current trends and lessons from history island regions and isolated communities represent an understudied area of not only clean energy development but also of innovation caribbean states have for some time shown interest in developing a regional sustainable energy policy and in implementing measures which could help to protect its member states from volatile oil markets while promoting reliance on local resources here we examine four case studies of renewable energy advancements being made by public utility companies and independent energy companies in the caribbean we attempt to locate renewable energy advances in a broader historical framework of energy sector development indicating a few policy lessons we find that different degrees of regulatory and legislative sophistication have evolved in different islands islands should have specialized policy focus contrasting the ad hoc nature of current regional energy policy discussion we also conduct a cost benefit analysis which shows that these early innovative alternative energy projects show themselves to be both profitable and significant sources of emissions reduction and job creation this lends support to the potential benefits of regional energy policy

the j curve a literature review due to lag structure currency devaluation is said to worsen the trade balance first and improve it later resulting in a pattern that resemble the letter j hence the j curve phenomenon since its introduction by magee in 1973 brooking papers on economic activity 1 pp 303 25 a large number of studies have attempted to test the phenomenon using different techniques and different model specifications the results are at best ambiguous and deserve to be collected together for the future generation of researchers and graduate students this paper fills such a vacuum in the literature by reviewing the j curve related empirical papers

paths of renewable energy development in small island developing states of the south pacific abstract pacific small island developing states psids are small and remote island economies highly reliant on fossil fuels although they are mainly self governing nations they are highly vulnerable to exogenous events such as global fuel price volatility and tropical cyclones the work presented here targets 12 psids located in the south pacific the analysis takes a functional approach to assess the state of the energy governance system and to determine its relationship to renewable energy re penetration using a suite of governance market and financial progress indicators a range of re preparedness levels was identified in psids analysis demonstrated that strengthening of re enabling indicators led to only a limited increase of re penetration consequently the region has fallen behind global rates of re uptake inward investment by development partners for re demonstration projects failed to be upscaled by government facilitated private sector the focus on mitigating global climate change has failed to put re into a local context this contrasts to the strong sense of place and spiritual nature of traditional pacific communities thus in energy terms psids are yet to attain a self defined energy identity

power sector reform in small island developing states what role for renewable energy technologies abstract due to various pressures and desires more and more developing countries embark on power sector reform programmes yet there are a wide range of reform options and at present insufficient evidence is available as to which path will deliver best the desired objectives presently most small island developing states sids are dependent on high cost fossil fuel imports for power generation in spite of evidence that harnessing abundant domestic renewable sources of energy can deliver environmental social and economic benefits however depending on the type of power sector reform the transition towards renewable energy technologies rets can be either undermined or facilitated the specific focus on sids is justified because they have inherent characteristics that limit the degree to which the power sector can be transformed in comparison to larger continental developing countries with specific reference to sids this manuscript reviews the drivers and desires for power sector reform as well as presenting the available reform options and their implications on the up take of rets in addition to elaborating aspects of market governance other barriers to the consideration of rets such as financial bias in investment human capacity and environmental policy are discussed in view of this discussion which is based on evidence from recent reform programmes and theoretical academic literature recommendations are formulated that discourage full privatisation of the power sector as well as proposing less dogmatic lending conditions by international assistance bodies

monetary policy elasticity dynamics and real exchange rate reversal models of hysteresis in trade invoke permanent shifts in competitiveness to explain the real exchange rate reversal of the 1980s these models predict an immediate and permanent response of competitiveness to exchange rate overshooting in contrast an extensive empirically based j curve literature suggests a lagged response of competitiveness to real exchange rate movements this paper shows that such trade balance elasticity dynamics offer an attractive alternative explanation of real exchange rate reversal copyright 1995 by ohio state university press

power sector reform in developing countries mismatched agendas power sector reform is rapidly spreading across all corners of the developing world at an alarmingly rapid pace while the rationales for reform seem to have gained acceptance among the stakeholders the reform model and process are contested this paper examines the impacts of reform using the promised outcomes as a basis for analysis the ability of reform to meet the developmental challenges facing the reformers is explored it concludes that reform has had some achievements if conventional performance indicators are used but also questions the validity of some of these indicators reform has however not fulfilled many of its goals and the prevailing recipes are likely to leave developing countries socially and economically worse off than in the pre reform period progressive government intervention is needed to shift reform process towards a more responsible development path

preventive care underused even when free is there something else at work explaining the rationale of preventive care underuse is a difficult task considering its great benefits for health underuse is even more difficult to explain in countries like italy where preventive care can be obtained for free in this article we investigate the determinants of prevention underuse with an empirical model based on human capital theory which also includes three factors to which little attention has been paid so far role played by the general practitioner gp nonmonetary barriers to access and health beliefs we apply a recursive probit model explaining both recourse to prevention and to the gp which allows us to adequately measure the effect of the latter on the former and to quantitatively compare the determinants of curative and preventive care we find that the gp plays a minor role in prevention use but that nonmonetary barriers to access and health beliefs are strong determinants of preventive care demand finally we also find support for both grossman s capital depreciation the

the j curve effect and us agricultural and industrial trade this paper examines the j curve hypothesis for us agricultural and manufactured goods using the shiller lag model the results support the j curve effect for agricultural goods but not for manufactured goods these findings explain why many studies in the literature fail to support the j curve phenomenon there are two explanations for these findings 1 the aggregation bias of data that combine both agricultural and manufactured goods and 2 the country under study is often an industrial nation like the us or japan with a high proportion of manufactured goods in both exports and imports

financing investments in renewable energy the impacts of policy design abstract the costs of electric power projects utilizing renewable energy technologies rets are highly sensitive to financing terms consequently as the electricity industry is restructured and new renewables policies are created it is important for policymakers to consider the impacts of renewables policy design on ret financing this paper reviews the power plant financing process for renewable energy projects estimates the impact of financing terms on levelized energy costs and provides insights to policymakers on the important nexus between renewables policy design and financing we review five case studies of renewable energy policies and find that one of the key reasons that ret policies are not more effective is that project development and financing processes are frequently ignored or misunderstood when designing and implementing renewable energy policies the case studies specifically show that policies that do not provide long term stability or that have negative secondary impacts on investment decisions will increase financing costs sometimes dramatically reducing the effectiveness of the program within u s electricity restructuring proceedings new renewable energy policies are being created and restructuring itself is changing the way rets are financed as these new policies are created and implemented it is essential that policymakers acknowledge the financing difficulties faced by renewables developers and pay special attention to the impacts of renewables policy design on financing as shown in this paper a renewables policy that is carefully designed can reduce renewable energy costs dramatically by providing revenue certainty that will in turn reduce financing risk premiums

fuelling the pacific aid for renewable energy across pacific island countries abstract pacific island countries have strong economic political and environmental incentives to switch from imported fossil fuels to indigenous renewable energy technologies and are well positioned to achieve such a switch given their ample renewable energy potential as well as their ambitious renewable energy goals for the pacific island countries to reach these goals however they depend on donor funding this paper therefore analyses energy related aid to the south pacific from 1990 through 2012 and specifically evaluates its development in three areas energy technology grid vs off grid solutions and project components using data from the organisation of economic cooperation and development i find a recent shift in donor thinking donors have over the past years put greater emphasis on renewable energy especially hydro and increasingly solar power donors have also invested more in off grid solutions often solar powered finally donors have begun to focus more on software that is capacity building training and policy making if pacific island countries together with the donors continue on this path they are well positioned to reach their ambitious renewable energy goals and to serve as an example for other countries both developing and developed islands and non islands

consumer preferences and willingness to pay for compact fluorescent lighting policy implications for energy efficiency promotion in saint lucia this article examines consumer willingness to pay for energy saving compact fluorescent light bulbs using the results of a stated preferences study conducted in the caribbean island nation of saint lucia geographic location low income status and age are found to affect willingness to pay for compact fluorescent lighting while higher income status and other demographic variables appear to have minimal or no significant impacts energy efficiency knowledge is associated with increased willingness to pay for energy efficient bulbs and with increased use of compact fluorescent lighting contrary to theoretical expectations past purchase of compact fluorescent bulbs is found to have no impact on self reported willingness to pay we hypothesize that this null result is due to the recent emergence of low cost low quality compact fluorescent bulbs in the saint lucian lighting market which may be negatively influencing consumers preferences and expectations regarding energy efficient lighting findings support the argument that government sponsored education and subsidy programs will likely result in increased use of energy saving technologies in saint lucia but such behavioral changes may not be sustained in the long run unless low quality bulbs the lemons of the compact fluorescent lighting market can be clearly identified by consumers

power sector renewable energy integration for expanding access to electricity in sub saharan africa abstract a looming energy supply crisis in sub saharan africa ssa raises concerns about a long lasting energy shortage this energy crisis is expected to persist for an indefinite period in the region unless immediate actions are taken to reverse the trend although global aspiration to reduce greenhouse gas ghg emissions into the atmosphere is high such desire is low in ssa regional stakeholders are more worried about increasing power generation capacity to enhance better access to different sorts of development to progress in line with advanced patterns of energy development globally to increase the availability of electrical energy and to sustain emissions reductions exploitation of local renewable energy re resources is inevitable consequently this paper presents a comprehensive review of re integration for expanding access to electricity in ssa the review covers the sustainability of re resources in ssa the regional status of re applications and the necessity of re power generation integration planning from a management aspect finally the benefits of re integration into the power sector of ssa and some conceptual challenges affecting its integration in the region are highlighted

do exchange rate changes have symmetric or asymmetric effects on the trade balances of asian countries abstractrecently the linear ardl approach was modified and a non linear version of the same approach that is used mostly to assess asymmetric effects of some exogenous variables on the dependent variable was introduced the non linear model was recently used by one study to show that indeed exchange rate changes have asymmetric effects on the trade balance of a few advanced countries the same was demonstrated for transition economies by another study in this article we provide additional asymmetric effects from seven asian economies by showing that in most cases we find evidence of short run and long run asymmetric effects of exchange rate changes on the trade balance like other studies our findings are country specific

the j curve revisited an empirical examination for the united states abstract this paper examines empirical evidence for trade prices and quantities for the united states to determine whether j curve effects have occurred in recent history empirical estimates of exchnage rate pass through and trade volume responses to exchange rate changes for the 1967 to 1987 period indicate that the often told tale of trade balance deterioration and then improvement the j shaped adjustment path has not typically been experienced by the united states expenditures on imports have typically increased following dollar depreciations primarily as a result of relatively inelastic import volume responses export earnings have been seen to rise only marginally during these same dollar depreciations due to increases in export prices and the subsequent reductions induced in export volume the long run merchandise trade balance adjustment path is seen to resemble a sine wave rather the a j

exchange rate of the us dollar and the j curve the case of oil exporting countries abstract this study examines the effects of changes in the exchange rate of the us dollar on the trade balances of three oil exporting countries namely iran venezuela and saudi arabia an exchange rate pass through model is applied to allow changes in the exchange rate of the dollar to affect prices of traded goods then the impact of changes in prices on the quantities of imports and exports of these economies is estimated the results suggest a partial exchange rate pass through to these countries import and export prices in terms of the us dollar while the three countries raise the price of their primary export namely crude oil in response to a depreciation of the dollar saudi arabia s long run pricing strategy in securing a larger market share stands in contrast to that of the two other opec members the sum of the estimated long run price elasticities of demand for imports and exports is found to exceed unity for iran and venezuela but less than unity for saudi arabia

green electricity in the market place the policy challenge the paper explores the implications of the liberalization of electricity markets in europe and north america for policy means and mechanisms to enhance the market penetration of renewables applying a co evolutionary approach the argument highlights the need for policy intervention to help producers and consumers move out of technological trajectories favoring non renewable electricity on the production side energy generation is locked into the central power station system deriving from more than a hundred years of technological development along a specific system trajectory on the consumption side the locked in effect results from a similarly long experience with electricity provision by monopoly suppliers and the associated lack of consumer choice and responsibility for product differentiation as the analysis shows policy strategies targeting both the production and consumption sides of the electricity market are needed for effective intervention furthermore policy strategies should draw on a clear analysis of the inertia and dynamism underlying the production and consumption of electricity in the light of such evolutionary dynamics the analysis demonstrates the insufficiency of the policy approaches currently employed to foster the market share of renewables based electricity instead the authors suggest a reflexive policy approach to initiate and support a reorientation towards green electricity emphasizing the need for learning and communication between and among societal actors

non monotonic health behaviours implications for individual health related behaviour in a demand for health framework a number of behaviours influence health in a non monotonic way physical activity and alcohol consumption for instance may be beneficial to one s health in moderate but detrimental in large quantities we develop a demand for health framework that incorporates the feature of a physiologically optimal level an individual may still choose a physiologically non optimal level because of the trade off in his or her preferences for health versus other utility affecting commodities however any deviation above or below the physiologically optimal level will be punished with respect to health distinguishing between two individual types we study a the qualitative properties of optimal time paths of health capital and health related behaviour b the perturbations of the optimal time paths that result from changes in exogenous parameters and c steady state properties predictions of the model and the implications for empirical analysis are discussed at length some comments on potential future extensions conclude the paper

an economic analysis for the design of ipp contracts for grid connected renewable energy projects abstract in this paper we undertake an integrated financial economic stakeholder analysis of a grid connected onshore wind project that is owned and operated by an independent power producer ipp in santiago island cape verde this ipp project has received considerable positive publicity and has won many awards cape verde has a very good wind resource but it suffers from high transportation costs for petroleum fuels due to its location hence it would appear to be an ideal site for an ipp investment in a wind farm this analysis is conducted from the perspectives of the electric utility the country s economy the government and the private sector investor the key question is whether the design of the power purchase agreement ppa can simultaneously yield a high enough cash flow for the project to be bankable while at the same time yielding a positive net financial and economic present value to the electric utility and the country respectively the analysis shows that a negotiated ppa results in a negative outcome for the economy of cape verde in almost all circumstances in contrast the owners of the ipp are guaranteed under all circumstances a very substantial return on their investment

exchange rates and traded goods prices abstract this paper presents a partial equilibrium model of the determination of domestic and export prices by a monopolistic competitive firm the model stresses the role of exchange rate uncertainty and expectations the most important result of the analysis is that the stochastic properties of deviations from the law of one price are crucially affected by the currency of denomination of export prices using data on domestic and dollar export prices of japanese goods i find that deviations from the law of one price are due to exchange rate surprises but also to price staggering and ex ante price discrimination

employer investments in employee health implications for the family as health producer the model presented in this paper further extends the demand for health model in which the family is the producer of health investments to consider the case in which an employer has incentives for investing in the health of a family member the household and the employer are assumed to interact strategically in the production of health the general insight provided is that the conditions which determine the nature of the relationship between the employer and the employee for instance market conditions production technologies taxes and government regulation will also affect the allocation of health investments and health capital within the family

policy measures to promote the widespread utilization of renewable energy technologies for electricity generation in the maldives abstract this study adopts a stakeholder based approach to understand the size and nature of the market and financial barriers to the widespread utilization of renewable energy technologies rets in the maldives in light of these barriers and the interests of relevant stakeholders this study evaluates different policy options in terms of their suitability to develop a domestic market for rets in the maldives evaluating the different policy instruments it was found that pricing laws that regulate market access are more suitable than quota systems provided that the current subsidies for conventional energy are removed or shifted towards rets as for the other financial incentives rebates on investments and low interest loans should be provided to ret project developers to overcome the high initial project costs in addition to these measures the limited institutional capacity suggests that policy support should also focus on enabling the steady development of regional institutions rather than on supporting individual ret projects these institutions should enable islands in each atoll to take advantage of efficient management and access to financial capital this will allow the development of sustained renewable energy projects that in turn will result in increased renewable capacity and decreased costs

importance of islands in renewable energy production and storage the situation of the french islands abstract the islands are often not or only partially connected to continental electrical networks and have to manage their energy supplies in reaching themselves the production demand balance while ensuring the quality of the delivered electricity the low consumption and the lack of interconnections induce higher energy costs than in other regions for increasing their security the islands prefer to use indigenous sources as renewable ones unfortunately the intermittence and stochastic character of these fatal energy sources make them more difficult to manage and it is aggravated in the case of small island networks the islands are good locations for using and testing new technologies of energy production and storage most islands have a good renewable energy re potential often underused the difficulties of electricity management in island grids are first shown particularly with the impact on the energy production cost then the problem of the integration of renewable energy sources res in island electrical grids is highlighted the energy situation of french islands is presented with a particular focus on the part of renewable sources a higher share of renewable energy in the energy mix can be reached only with the development of the energy production efficient prediction with the development of energy storage means and with an optimal management of the energy flux via the utilization of smart grids

uncertainty inequalities in health and the demand for health abstract as it has become increasingly recognized that inequalities in health stem more from inequalities in wealth rather than from inequalities in access to medical care economists have begun to suggest that michael grossman s model of the demand for health may be a useful analytical framework for investigating the issue ironically the more popular of grossman s two sub models the pure investment model provides little by way of insights into the relationship between inequalities in wealth and inequalities in health in common with other pure investment models of human capital formation grossman s model predicts that an individual s health investment decisions at each stage in the lifecycle will be independent of his initial wealth this paper shows that if uncertainty is introduced into the model this result no longer holds it also shows that if individuals display decreasing absolute risk aversion wealthier individuals will invest more in health capital than individuals who start life with relatively small stocks of financial capital

reform despite politics the political economy of power sector reform in fiji 1996 2013 abstract attempts to reform the electricity sector in developing countries have achieved mixed results despite the implementation of similar reforms in many developed countries and concerted effort by donors to transfer reform models in many cases political obstacles have prevented full and effective implementation of donor promoted reforms this paper examines the political economy of power sector reform in fiji from 1996 to 2013 reform has been pursued with political motives in a context of clientelism policy inconsistency and reversal is explained by the political instability of ethnic based politics in fiji modest success has been achieved in recent years despite these challenges with fiji now considered a model of power sector reform for other small islands developing states sids in the pacific the experience demonstrates that reform is possible within difficult political environments but it is challenging takes time and is not guaranteed the way in which political motives have driven and shaped reform efforts also highlights the need for studies of power sector reform to direct greater attention toward political drivers behind reform

electricity generation cost in isolated system the complementarities of natural gas and renewables in the canary islands abstract the canary islands offer an example of an isolated electric grid of relative important size within the eu due to its peculiarities the role of renewable energies and their complementarity with fossil fuels offers a solid path to achieving the main energy policy goals of the islands the purpose of this paper is to assess the current situation and the energy objectives proposed in the energy plan of the canaries pecan 2006 for the electricity industry taking into account the average cost and the risk associated with the different alternatives for generating electricity by means of the mean variance portfolio theory our analysis highlights the inefficiency of the current electricity generating mix in terms of cost risk and lack of diversification shifting toward an efficient system would involve optimizing the use of endogenous energy sources and introducing natural gas to generate electricity this scenario would mean reducing both cost and risk by almost 30 each as well as atmospheric co 2 emissions our results agree with the pecan philosophy

the family as producer of health an extended grossman model deriving a model where each family member is the producer of his own and other family members health shows that the family will not try to equalise marginal benefits and marginal costs of health capital for each family member they will rather invest in health until the rate of marginal consumption benefits equals the rate of marginal net effective costs of health capital the level of compensation in the social insurance system the effective price of care health related information and transfer payments will all affect the production possibility set and therefore the optimal level and distribution of family health

consumption and investment demand when health evolves stochastically abstract the health capital model of grossman 1972 is extended to account for uncertainty in the rate at which a stock of health depreciates two general versions of the model are contemplated one with a fully functioning financial market and the other in its absence the comparative dynamics of the feedback form of the consumption and health investment demand functions are studied in these general settings where it is shown that the key to deriving refutable results is to determine how a parameter or state variable affects the expected lifetime marginal utilities of health and wealth to add further reach to the results a simplified stochastic control problem is explicitly solved yielding estimable structural feedback demand functions

estimation of j curves united states and canada delayed reactions to exchange rate changes in trade on current account balances are known to exist in both the united states and canada a model has been constructed to estimate relative price effects for trade with major partners in order to determine the quantitative magnitudes and relevant time delays for both countries adjustments in trade accounts there is a distinct tendency for balances to worsen when exchange depreciation first occurs and then to improve after several quarters have passed there is also a tendency for the balances to worsen again the u s and canadian time profiles of adjustment are found to be similar

demand for health a generalised grossman model the demand for health and medical care is analysed within a generalised grossman type health investment model its underlying assumptions are shown to differ from those employed earlier in a manner which avoids some of the criticisms levelled at grossman s model the comparative static predictions of the generalised model are examined and it is demonstrated that most previous health investment models are derivable from it also the present model is applicable to a new wider range of problems thus increasing the scope of economic explanations of health behaviour

assessing the determinants of sids pattern toward sustainability a statistical analysis abstract the aim of this paper is twofold first we assess the sids pattern towards energy sustainability second we try to understand the macro factors that drive policy makers in setting the optimal framework for investments in renewable energy sources the empirical analysis is performed on a large dataset of 136 countries and 41 variables observed in the time span 2000 2011 countries analyzed include a sample of 12 sids bahrain cuba dominican republic fiji islands guyana haiti jamaica maldives mauritius papua new guinea singapore trinidad and tobago distributed worldwide due to the large number of variables collected and their high degree of collinearity the first step of the analysis concerns the implementation of a principal component analysis in order to extract factors explaining the majority of variation of the original variables in the second step three different scenarios of modeling are designed to examine the key factors promoting res investments in a first scenario we employ a pooled regression model in the second a fixed effect model and in the third a random effect model is estimated the main results of empirical analysis could be unexpected at first sight they show in fact that sids are not on a energy sustainability path as in the case of other developing countries policy makers prefer to use resources to improve economic aspects of development leaving behind issues related to the environmental protection the use of res and sustainability in order to improve economic and environmental resilience of sids a synergy between local governments and international organizations to promote the investments in res is needed moreover an energy plan that clearly supports the generation of energy from res is recommended finally policy makers should strength their commitment in raising population s awareness toward a green energy generation such synergic interventions will allow sids to achieve a more sustainable development
