capital mobility and foreign debt sustainabilty some evidence from turkey this paper address the extent of capital mobility and foreign debt sustainability in turkey over the 1962 2003 period by examining the relationship between saving and investment and imports and exports respectively the empirical investment is based on cointegration error correction models and threshold and momentum threshold autoregressive models our findings are consistent with the existence of capital mobility and the strong form of foreign debt sustainability

elements for the development of public policies in the residential sector of mexico based in the energy reform and the energy transition law abstract mexico has entered in an important dynamic of structural changes in the energy area proof of this it is the energy reform 2013 and the energy transition law published the last december 24th 2015 thus it is important to carry out studies of the impacts of future politics in the consumption of the population so this study estimate an energy demand system using microdata collected from 97 817 households in a national households income and expenditure survey enigh acronyms in spanish encuesta nacional de ingresos y gastos de los hogares in the 20 years period from 1994 to 2014 the magnitudes of all the fuels are smaller than one indicating that electricity lpg gasoline and public transport are normal goods while lpg is the most inelastic energy source the geographic factor shows that households in the north of mexico tend to consume more gasoline whereas in the south of the country the lowest share of lpg expenditure is reported the rigorous evaluation of energy demanded in households will help policy makers to put forward more efficient reforms

fuel demand elasticities for energy and environmental policies indian sample survey evidence india has been running large scale interventions in the energy sector over the last decades still there is a dearth of reliable and readily available price and income elasticities of demand to base these on especially for domestic use of traditional fuels this study uses the linear approximate almost ideal demand system la aids using micro data of more than 100 000 households sampled across india the la aids model is expanded by specifying the intercept as a linear function of household characteristics marshallian and hicksian price and expenditure elasticities of demand for four main fuels are estimated for both urban and rural areas by different income groups these can be used to evaluate recent and current energy policies the results can also be used for energy projections and carbon dioxide simulations given different growth rates for different segments of the indian population

sustainability of current account deficits in india an intertemporal perspective this study examines the sustainability of current account deficits cads and the validity of intertemporal budget constraint ibc in india the long run model is estimated on annual data for the period 1950 1951 to 2009 2010 the optimal single equation and maximum likelihood ml system estimates of the model provide a consistent support for the long run relationship between imports and exports the olsgh estimates provide no support and that ml system estimates a consistent support for cointegration in both the models estimated with one and two structural breaks in level the new cointegration breakdown tests generally suggest that the cointegration prevails from 1951 to 2010 the evidence supporting the cointegration between imports and exports overwhelms the evidence providing a mixed or no support for cointegration the estimates of slope parameter above zero and the dominant support for cointegration between imports and exports vindicate the validity of ibc and the sustainability of cads the shor

household fuelwood demand and supply in nepal s tarai and mid hills choice between cash outlays and labor opportunity abstract subsistence households are a leading source of deforestation and their consumption of fuelwood in particular is important in many developing countries yet the empirical economic examinations of fuelwood consumption are sparse particularly for rural areas where the deforestation occurs and we would argue that forest policy is often designed without a good understanding of the potential responses of subsistence households to the new policy this paper addresses these issues with household evidence from the two major populated regions of nepal market prices labor opportunities the availability of substitutes and measure of access to the basic resource are the most reliable predictive variables for fuelwood consumption and production there are however regional differences and important distinctions between the elasticities of fuelwood collecting or purchasing households with respect to these predictive variables the difference between collecting and purchasing households is notable it recommends forestry policies that target the labor opportunity and the physical resource in regions where collecting households dominate and policies that affect the fuelwood market itself in regions where purchasing households are important a second interesting finding is that fuelwood is relatively scarcer prices are higher in the mid hills and both collecting and purchasing households in this region are beginning to respond to deforestation by using their own land for fuelwood production

wage bargaining central bank independence and the real effects of money the effects of financial capital mobility on monetary policy autonomy are relatively well understood but the importance of particular monetary regimes in distinct national institutional settings is not this article is a theoretical and empirical exploration of the effects of monetary policy regimes on unemployment in different national wage bargaining settings based on a rational expectations two stage game of the interaction between the wage behavior of labor unions and the monetary policies of governments i argue that monetary policies have real employment effects in all but the most decentralized bargaining systems specifically in intermediately centralized bargaining systems a credible government commitment to a nonaccommodating monetary policy rule will deter militant wage behavior with salutary effects on unemployment in highly centralized systems by contrast restrictive monetary policies will clash with unions pursuit of wage distributive goals and produce inferior employment performance only in highly fragmented bargaining systems is money neutral in the sense that employment performance is unaffected by monetary regimes the model has clear consequences for the optimal design of central banks and collective bargaining arrangements and suggests new ways to study institutional change hereunder the causal effect of increasingly globalized capital markets the argument is supported by pooled time series data for fifteen oecd countries over a twenty one year period

global imbalances and the intertemporal external budget constraint a multicointegration approach abstract this paper analyzes the external solvency of a group of 23 oecd countries for the period 1970 2012 the empirical strategy adopted underlines the increasing importance of the financial channel for the external adjustment as proposed in gourinchas and rey 2007 we unify the traditional approaches to testing for external sustainability considering the stock flow system created by the variables representing the external relationships of an open economy external sustainability is tested using several types of cointegration and multicointegration tests the results obtained point to weak sustainability in the flows analysis whereas some degree of strong sustainability is found for up to six countries in the stock flow approach among these countries we find both non european economies such as japan and new zealand and euro area members especially those with more restricted access to financing in the international markets

the bargaining system and performance a comparison of 18 oecd countries theoretical reasoning disagrees about what type of bargaining system performs best the authors have tested the explanatory power of three competing hypotheses neoliberalism corporatism and the hump shape hypothesis all of these hypotheses lack empirical support due to two main shortcomings first they ignore that wage restraint raises three distinct types of collective action problems second they do not consider qualitative differences among the national bargaining systems particularly the role of the state that do not allow analysis to construct such ordinal rankings of bargaining coordination as adopted by all previous empirical studies proceeding from a revised hypothesis and new measures of national bargaining systems the authors have found a nonlinear relationship between the bargaining system and economic performance in a way that economy wide wage coordination is superior only when the bargaining system is able to make local bargaining comply with coordination activities

equity externalities and energy subsidies the case of kerosine in indonesia abstract this paper examines two arguments used to justify the subsidy provided kerosine the primary commercial fuel of indonesian households one argument holds that the subsidy reduces deforestation externalities resulting from wood gathering econometric analysis of a large cross section of households finds that firewood kerosene substitution is very limited in java where the deforestation problem is most severe so that kerosene subsidy is not an effective means of alleviating the problem the second argument holds that social equity requires the subsidization of basic needs such as kerosene it is found that the kerosene subsidy disproportionately benefits urban and wealthier households

the effect of labor market performance on deforestation in developing countries under open access an example from rural nepal abstract this research examines the deforestation behavior of smallholder agriculturalists as off farm labor market conditions change a model of a representative village is proposed which incorporates dependence on open access forests for fuelwood and animal raising dynamic simulations are then presented which compare time paths of forest stocks deforestation levels and household labor supply under a variety of conditions despite the open access regime assumed in the model with a perfect albeit low wage off farm labor market the agro forestry system in nepal is basically stable an alternative model where there is no off farm labor market eliminates the important features of adjustment to deforestation which generate forest stability suggesting that the availability of off farm opportunities is an important determinant of deforesting behavior and equilibrium forest stock levels

the dynamics of trade unionism and national economic performance i test two theories of the political processes of trade unions the first argues that wage moderation depends on a centralized labor movement the second contends that institutional conditions permitting unions coordination of bargaining strategies is sufficient coordination is most likely to he achieved when there are small number of unions that do not compete for members that is when union monopoly is high important empirical anomalies may be resolved by analyzing the effects of union centralization and monopoly separately rather than combining them into a composite index of corporatism reanalyzing comparative data from organization of economic cooperation and development countries between 1963 and 1985 largely corroborates the hypothesis that monopoly is more important than either centralization or composite indices of corporatism for national economic performance the conceptual rationale underlying indices of corporatism should be reexamined

modelling household energy expenditures using micro data this paper is concerned with the empirical modeling of domestic demand for energy in the united kingdom at the level of the individual household a two stage budgeting model of household demand for energy conditional on durable ownership is developed at the first stage income is allocated between energy and nonenergy consumption while at the second stage energy expenditure is disaggregated the second stage allocation is assumed to be between gas electricity and a composite good other fuels estimation takes place using a sample of some 50 000 households drawn from the annual u k family expenditure survey for the years 1972 83 a source that has not been fully exploited in the analysis of energy demand to date copyright 1989 by royal economic society

from linear fuel switching to multiple cooking strategies a critique and alternative to the energy ladder model abstract promoting sustainable development requires evaluating the technical and policy options that will facilitate the adoption and use of energy efficient and less polluting cooking stoves and practices the transition from traditional to modern fuels and devices has been explained by the energy ladder model that suggests that with increasing affluence a progression is expected from traditional biomass fuels to more advanced and less polluting fuels in this paper we evaluate the energy ladder model utilizing data from a four year 1992 96 case study of a village in mexico and from a large scale survey from four states of mexico we show that an alternate multiple fuel model of stove and fuel management based on the observed pattern of household accumulation of energy options rather than the simple progression depicted in the traditional energy ladder scenario more accurately depicts cooking fuel use patterns in rural households the multiple fuel model integrates four factors demonstrated to be essential in household decision making under conditions of resource scarcity or uncertainty a economics of fuel and stove type and access conditions to fuels b technical characteristics of cookstoves and cooking practices c cultural preferences and d health impacts this model also allows better estimates of the expected fuelwood demand and indoor air pollution in rural households

mixed signals central bank independence coordinated wage bargaining and european monetary union plans for the european monetary union emu are based on the conventional postulate that increasing the independence of the central bank can reduce inflation without any real economic effects however the theoretical and empirical bases for this claim rest on models of the economy that make unrealistic information assumptions and omit institutional variables other than the central bank when signaling problems between the central bank and other actors in the political economy are considered we find that the character of wage bargaining conditions the impact of central bank independence by rendering the signals between the bank and the bargainers more or less effective greater central bank independence can reduce inflation without major employment effects where bargaining is coordinated but it can bring higher levels of unemployment where bargaining is less coordinated thus currency unions like the emu may require higher levels of unemployment to control inflation than their proponents envisage they will have costs as well as benefits and these will be unevenly distributed among and within the member nations depending on the changes they induce in the status of the bank and of wage coordination

saving investment dynamics and capital mobility in the us and japan abstract this paper points out that a high long run correlation between saving and investment is better interpreted as reflecting the operation of a country s intertemporal budget constraint rather than as an indicator of capital mobility inferences about capital mobility can instead be made from the divergent short run dynamic responses of saving and investment to shocks using post war quarterly data for the us and japan the paper assesses the characteristics of saving and investment behavior under different regulatory environments it finds mixed evidence of changes in the short run dynamics of saving and investment that suggest increased capital mobility in the 1980s

consumption of fuelwood and other household cooking fuels in indian cities abstract the purpose of this article is to use two recent household surveys held in hyderabad and raipur india to examine the determinants of household cooking energy consumption and the role of traditional fuels this analysis suggests that the amount of cooking fuel used per household does not vary substantially with household income higher incomes are however associated with a larger share of modern fuels and as these fuels are more efficient than traditional fuels a higher level of energy services fuel prices appear to influence both the level of energy consumption for cooking and the mix of fuels used consumer preference and reliability of supplies also play a role

do remittances facilitate a sustainable current account we examine how workers remittances impact on the current account in doing so we focus on how remittances affect the sustainability rather than the size of current account balances we find that the presence of remittances makes it more likely that exports and imports are cointegrated thereby lending support to current account sustainability furthermore quantile regression analysis suggests that increased remittances are associated with a faster speed of current account adjustment towards long run equilibrium particularly for those countries characterised by already highly persistent current account balances in contrast to a literature that emphasises an adverse dutch disease impact of workers remittances on the real exchange rate in terms of reduced external competitiveness our findings suggest that remittances are actually beneficial to the current account balance

natural resources agriculture and property rights abstract the study explores empirically forest resource and soil quality degradation under different property rights regimes in a subsistence agriculture framework the quantitative analysis is a direct test of the theoretical hypothesis of larson and bromley 1990 larson b bromley d 1990 property rights externalities and resource degradation locating the tragedy journal of development economics 33 2 that common property and private property rights may lead to similar incentives for resource protection a household model is formulated and applied empirically with data from indonesia to test rates of forest biomass and soil quality degradation under private and common property rights results show that the two regimes may equal each other by including bequest value sensitivity analysis is conducted by changing model parameters

union strength neoliberalism and inequality contingent political analyses of u s income differences since 1950 do historically contingent political accounts help explain the growth in family income inequality in the united states we use time series regressions based on 60 years to detect such relationships

preferences for domestic fuel analysis with socio economic factors and rankings in kolkata india abstract the choice of domestic fuel is a matter of great concern for households and policy makers in india this paper investigates the demand for domestic fuels when households face four choices fuelwood coal kerosene and lpg the study is based on a survey of 500 households in kolkata india the demand estimates are conducted using a two stage process where the first stage investigates choice and the second the quantity used determinants of fuel demand are identified and their relative importance shown extending the study the paper also analyses the choice of the main cooking fuel in terms of the households stated rankings of six fuels for five attributes the policy discussion indicates that subsidies have less potential to reduce polluting fuels such as coal and fuelwood due to weak cross price elasticities while increased availability of lpg and potentially also increased awareness of indoor air pollution have greater prospect

mean reversion of the current account evidence from the panel data unit root test abstract theoretically the modern intertemporal model of current account determination implies the stationarity of the current account however the empirical finding in the literature indicates nonstationary current account balances based on conventional unit root tests applying the panel data unit root test of im pesaran and shin we find support for the mean reverting property of the current account this in turn lends support to the intertemporal approach to the current account the policy implication of our findings is that current account deficits in major industrial countries are sustainable

nepali fuelwood production and consumption regional and household distinctions substitution and successful intervention this article uses household data from nepal s two major populated regions and 27 of 59 districts within those regions to examine fuelwood consumption and production in contrast with a purely market assessment household analysis includes production which is consumed in the producing household the household regressions yield coefficients and elasticities that are very different from and more reliable than a comparable assessment of market demand and supply household results generally support the hypotheses that expenditures on fuelwood are a small share of total household activity and that fuelwood is not sufficiently scarce to alter household behaviour fuelwood is sufficiently scarce however to alter behaviour for those households in the hill region that do not participate in market exchange these households may be the best targets for public market interventions designed to alter fuelwood supply and deforestation

a two stage rural household demand analysis microdata evidence from jiangsu province china in this paper we evaluate economic and demographic effects on china s rural household demand for nine food commodities vegetables pork beef and lamb poultry eggs fish sugar fruit and grain and five nonfood commodity groups clothing fuel stimulants housing and durables a two stage budgeting allocation procedure is used to obtain an empirically tractable amalgamative demand system for food commodities which combine an upper level aids model and a lower level gles as a modeling framework the results indicate that the slow growth of food consumption in china during the latter half of the 1980s is a result of income stagnation rather than consumption saturation growth in the demand for better food and shelter by chinese rural households will continue to be a major concern

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

fuelwood consumption and forest degradation a household model for domestic energy substitution in rural india this paper disusses domestic en ergy supply and demand in rural india links be tween forest scarcity and household fuel collec tion are analyzed in a non separable household model focusing on substitution of non commer cial fuels from the commons and the private do main based on data from villages bordering a protected area a novel maximum entropy ap proach is used for estimation it is found that households respond to forest scarcity and in creased fuelwood collection time by substituting fuels from private sources for forest fuelwood however the magnitude of the response appears insufficient to prevent current fuelwood collection practices from causing serious forest degrada tion jel q24

consumer behaviour theory and empirical evidence a survey this survey is designed to emphasize the relationship between empirical a nd theoretical considerations in the analysis of consumer behavior a lthough it focuses primarily on analysis at the individual or micro l evel it tries where possible to draw implications for the estimati on of aggregate relationships the importance of micro level analysis stems from the rapid expansion in available panel and survey data se ts this development has generated its own theoretical and empirical issues many of which are raised in this survey copyright 1988 by royal economic society

household energy demand in kenya an application of the linear approximate almost ideal demand system la aids abstract this paper estimates price and fuel expenditure elasticities of demand by applying the linear approximate almost ideal demand system la aids to 3665 households sampled across kenya in 2009 the results indicate that motor spirit premium msp automotive gas oil ago and lubricants are price elastic while fuel wood kerosene charcoal liquefied petroleum gas lpg and electricity are price inelastic kerosene is income elastic while fuel wood charcoal lpg electricity msp and ago are income inelastic the results also reveal fuel stack behaviour that is multiple fuel use among the households main policy implications of the results include increasing the penetration of alternative fuels as well as provision of more fiscal incentives to increase usage of cleaner fuels this not withstanding however the household income should be increased beyond a certain point for the household to completely shift and use a new fuel

effective tax rates in macroeconomics cross country estimates of tax rates on factor incomes and consumption abstract this paper proposes a method for computing tax rates using national accounts and revenue statistics using this method we construct time series of tax rates for large industrial countries the method identifies the revenue raised by different taxes at the general government level and defines aggregate measures of the corresponding tax bases this method yields estimates of effective tax rates on factor incomes and consumption consistent with the tax distortions faced by a representative agent in a general equilibrium framework these tax rates compare favorably with existing estimates of marginal tax rates and highlight important international differences in tax policy

demand for beef and chicken products separability and structural change several studies have indicated that the recent shift from beef to poultry in consumption is not entirely caused by changes in rela tive prices or income braschler chavas dahlgran hudson and vertin moschini and meilke frank thurman most studies of structural change have focused on red meat consumption only thurman has looked closely at the poultry market and no one has considered poultry products yet the mix of chicken products marketed changed dramat ically during the last twenty years and should have influenced aggregate meat demand the share of broiler slaughter marketed as whole birds declined from 74 in 1965 to 28 in 1985 while cut up parts and processed chick en products increased from 26 to 72 whole birds are inferior goods and cut up parts and processed chicken are normal goods haidacher et al the shift in chicken prod uct mix away from whole birds should have increased the preference for total chicken in this article two related questions are ad dressed first do consumers allocate expendi tures among meats by animal origin or by product type second does disaggregation of meat into products in a meat demand model give insight into the causes of structural

joint production and consumption in traditional households fuelwood and crop residues in two districts in nepal forest conversion by agricultural households is the leading cause of deforestation yet we know little about agricultural household use of forest and tree products this article measures household production of and demand for fuelwood and fuel substitutes in two districts in nepal women play a larger role in collection in the district dependant on production from common forestlands men and agricultural capital are more important inputs in the district dependant on production from private lands the article also measures demand elasticities for fuelwood combustible agricultural residues and improved stoves a technological substitute each by household income group all price and income demand elasticities are less than one the substitution elasticities between residues and fuelwood are less than one residues are more important substitutes for low income households and improved stoves are more important substitutes for high income households

welfare implications of community forest plantations in developing countries the orissa social forestry project community forest plantations are a common intervention in developing countries we use household and remote sensing data from orissa india to estimate welfare effects of community forest plantations in terms of the value of decreased collection times plantations afford users a selection model accounting for possible jointness in site location and productivity is used to estimate collection production functions for different household labor categories in natural and community forests two measures of an opportunity cost of time are used to determine welfare effects of time saved due to community forests we find access to community forests is important to marginal productivity of different labor categories but to different degrees highlighting the need to disaggregate household data when analyzing these interventions we also find substantial welfare improvements from time savings for many households and villages

disease microdams and natural resources in tigray ethiopia impacts on productivity and labour supplies we examine the effects of water microdams and ensuing waterborne diseases on household decisions in tigray ethiopia where the government implemented a water resource development programme two decades ago we find microdams increase productivity of both fuelwood collection and crop production but the costs of these dams to households can be significant in villages close to dams disease prevalence is higher and all household labour categories spend more time sick and more time is spent by male and female adults caring for sick family members these can cost the household anywhere in the region of 150 250 birr per season depending on the type of labour diversion and the productivity of labour males are most significant here removing their time from production results in 40 60 per cent higher productivity and income losses compared to diversion of female labour sick households also spend significantly more money on health care especially when male and female adults are sick

dynamics of fuelwood prices in india policy implications abstract this paper examines the changes in prices of fuelwood in urban centers over the years in india fuelwood prices have risen in india relative to prices of other commodities this has been the combined effect of increase in demand for fuelwood and decrease in supply of fuelwood due to degradation and depletion of forests policy interventions needed to change the situation are i increasing commitment for conserving existing forests ii stimulating the use of fuel efficient cookstoves to contain fuelwood demand and iii stimulating agroforestry systems and wasteland plantations

testing for the sustainability of the current account deficit in two industrial countries abstract the objective of this paper is to test for the sustainability of the current account deficits in the united states and canada over the 1973 1994 period using various unit root and cointegration tests some of which allow for structural changes we conclude that the real current account deficits to gdp ratios are not sustainable

demographic variables in demand analysis in this paper the authors discuss five procedures for incorporating demographic variables into theoretically plausible demand systems translating scaling and the gorman reverse gorman and implicit prais houthakker procedures these five procedures are used to incorporate a single demographic variable the number of children in a household into the generalized ces demand system using household budget data for the united kingdom for the period 1966 1972 excerpt

startup costs and the decision to switch from firewood to gas fuel firewood remains a key source of energy for households in developing countries contributing to forest degradation and deforestation the adoption of alternative fuels may be hindered by high startup costs and this problem may be compounded by restrictions in credit availability we use survey data to examine how credit access affects firewood consumption in guatemala our results suggest that access to credit plays a statistically significant role in determining firewood consumption through its effect on the ability to purchase a gas stove however simulations suggest that these effects are small and that subsidizing stoves would be amore promising policy for reducing firewood consumption

wage setting measures a survey and assessment wage setting has been one of the most heavily studied institutions in the field of comparative political economy over the past two decades and quantitative measures of wage setting arrangements have played a major role in this research yet the proliferation of such measures in recent years presents researchers with a sizable array from which to choose in addition some scholars are rather skeptical about the validity and or reliability of these measures this article offers a survey and assessment of fifteen wage setting measures it attempts to answer questions about 1 how these indicators differ from one another in conceptualization and measurement strategy 2 which are the most valid and reliable 3 the strengths and weaknesses of measures of wage centralization versus those of wage coordination 4 particular countries or time periods for which there are noteworthy discrepancies in scoring 5 how sensitive empirical findings are to the choice of wage setting measure

natural resource collection work and children s schooling in malawi abstract this paper presents results of research that investigates if long hours of work spent by children in fuel wood and water collection activities i e natural resource collection work influence the likelihood that a child aged 6 14 attends school potential endogeneity of resource collection work hours is corrected for using two stage conditional maximum likelihood estimation data from the 1997 1998 malawi integrated household survey ihs conducted by the malawi national statistics office nso in conjunction with the international food policy research institute ifpri are used the study finds that malawian children are significantly involved in resource collection work and their likelihood of attending school decreases with increases in hours allocated to this work the study further shows that girls spend more hours on resource collection work and are more likely to be attending school while burdened by this work consequently girls may find it difficult to progress well in school however girls are not necessarily less likely to be attending school results further show that presence of more women in a household is associated with a lower burden of resource collection work on children and a higher probability of children s school attendance finally the research shows that children from the most environmentally degraded districts of central and southern malawi are less likely to attend school and relatively fewer of them have progressed to secondary school compared to those from districts in the north

richer and healthier but not greener choices concerning household energy use in india india is among the world lowest per capita greenhouse gas ghg emitters but rapid increases are expected at the same time world health organization who estimates show that 424 000 die prematurely in indian households each year from air pollution exposure due to solid fuel use we analyze ghg emissions and health through three policy scenarios for household energy using projections for population income and urbanization in policy scenarios called business as usual bau improved health and green future projected per capita household ghg emissions in 2026 increase by 169 164 and 139 respectively compared to 2001 whereas household mortality rates decrease by 45 67 and 45 respectively due to income growth and urbanization an increase in ghg emissions is likely inevitable but can be slowed for health in contrast improvements are expected and can be expanded

unconditional elasticities in two stage demand systems an approximate solution two stage budgeting postulates that the consumer s utility maximization decision can be decomposed into two steps in the first stage total expenditure is allocated over broad groups of goods in the second stage group expenditures are allocated over elementary commodities in this article we assume that the current weighted true cost of living price indices defined for each broad group of elementary commodities vary only very slightly with sub utility levels hence it is possible to approximate the first stage of a two stage budgeting structure by a maximization problem involving a single price index and a single quantity index for each of the broad groups relationships between conditional and unconditional expenditure and price elasticities are derived within this context

current account deficit sustainability the case of barbados this article investigates the sustainability of the current account deficit in barbados over the period 1960 to 2006 various unit root and cointegration techniques are employed to determine whether the country is satisfying its intertemporal budget constraint ibc the cointegration regressions suggest that the current account of barbados is sustainable and that deviations from long run equilibrium between real exports and imports are corrected in the short run with imports making the adjustment

fuelling calorie intake decline household level evidence from rural india summary in india average calorie intake has declined even as real monthly expenditure has increased since cross sectional evidence suggests a positive relationship between the two variables the trend emerges as a major puzzle using household level data from four recent rounds of national sample survey data on consumption expenditure and a novel instrumental variable estimation strategy we find that rising expenditure on non food items is one of the factors that has led to the calorie intake decline we provide causal evidence for such a food budget squeeze in the case of one type of non food item viz expenditures on cooking fuel

the environmental impact of poverty evidence from firewood collection in rural nepal abstract we investigate determinants of household firewood collection in rural nepal using 1995 96 and 2002 3 world bank living standards measurement survey lsms data we incorporate village fixed effects endogenous censoring measurement error in living standards and heterogeneous effects of different household assets we find no evidence in favor of the poverty environment hypothesis the evidence for the environmental kuznets curve depends on the precise measure of living standards and time period studied firewood collections fall with a transition to modern occupations and rise with increasing population and household division the local interhousehold collection externality is negligible indicating that policy interventions are justified only by ecological considerations or nonlocal spillovers

are current account deficits sustainable evidence from panel cointegration abstract conventional cointegration tests fail to consider information across countries which leads to efficiency loss in estimation in this article we apply panel cointegration tests to examine the cointegration between exports and imports among the g7 our findings support the sustainability of current accounts among major industrial countries which lends support to the intertemporal approach to the current account

causality and comovement between taxes and expenditures historical evidence from argentina brazil and mexico abstract this paper presents empirical tests for stationarity of fiscal deficits for three latin america countries it also examines the causality patterns between government expenditures and government revenues long historical series covering most of the 20th century for argentina brazil and mexico are used the findings suggest that deficits were stationary in argentina and mexico but not in brazil

government budget deficits and trade deficits are present value constraints satisfied in long term data abstract we test whether long term data from the u s and u k are consistent with the intertemporal government budget constraint and external borrowing constraint both individually and simultaneously a very strong test is provided by our focus on whether the present value constraints pvcs continue to hold despite unusual events such as wars that cause a structural break in the short run dynamic behavior of the variables we find that the pvcs hold over the whole sample period the data also indicate that the pvcs continue to hold following events that cause a structural break in the short run dynamics

distributional effects of subsidy removal and implementation of carbon taxes in mexican households abstract this paper presents a microsimulation using data from the national households income and expenditure survey nhies from 1994 to 2010 to determine the distributional effects of the price changes arising from energy and environmental policies and their impact on mexican households we reported simulations of several changes in energy prices as a result of partial or total energy subsidy removal including carbon tax in order to examine whether the subsidy mechanism and carbon tax tend to be progressive or regressive we evaluated the households burden in different income levels these simulations respond to the need for an assessment of economic and environmental impacts of energy subsidies in mexico this is of great importance for mexico because of effort that has been taken in the development of energy policies and the rising interest of the mexican government in mitigating carbon dioxide co2 emissions and their concomitant environmental damage

are forest incomes sustainable firewood and timber extraction and productivity in community managed forests in nepal summary lack of combined forest productivity and income studies means there is scant evidence for the sustainability of rural household level forest incomes in developing countries this study examines levels and patterns of forest increment wood product extraction and household level incomes in three community managed forests in nepal using data from 240 permanent sample plots and a structured household survey conducted in 2006 and 2009 n 507 and 558 respectively we find that analyses of sustainability need to recognize the complexity of forest stand utilization and that there is considerable scope by altering how existing local forest management rules are implemented for increasing rural household forest incomes while keeping harvesting levels sustainable

the nonneutrality of monetary policy with large price or wage setters monetary rules matter for the equilibrium rate of employment when the number of price wage setters is small even when assuming rational expectations complete information central bank precommitment and absence of nominal rigidities if the central bank is nonaccommodating sufficiently large unions bargaining independently have an incentive to moderate sectoral money wages and thereby expected real wages the result is an increase in the real money supply and hence higher demand and employment this does not hold with accommodating monetary policy since unions wage decisions cannot then affect the real money supply a similar argument holds for large monopolistically competitive price setters

analysis of food away from home expenditure patterns for u s households 1982 89 the two step decision process for food away from home fafh consumption is empirically estimated using a generalization of the heien and wessells approach household information gathered by the national panel diary group is used for the analysis marginal effects are corrected by untangling the respective variable impacts on the inverse mills ratio expenditure and participation probability elasticities are similar to previous studies income elasticities are about 0 20 suggesting that the fafh commodity is a necessary good for u s society northeastern households are less likely to consume fafh than other households but their expenditures are higher on average

urban fuelwood challenges and dilemmas abstract this paper explores the use of fuelwood in third world cities the importance of fuelwood and the factors which condition its use in cities are set out and three fuelwood problems are identified the cost to urban consumers fuel supply security and the impact of urban fuelwood markets on rural areas urban fuelwood interventions are evaluated with four categories identified interventions in marketing conservation increased wood production and fuel switching of these fuel switching by improved supply systems and increased production from smallholders and better management of natural woodlands appear to have the greatest potential the need for flexibility community participation in planning is stressed

the incidence of fuel taxation in india abstract fuel taxes have returned to centre stage as a potential policy instrument for greenhouse gas abatement on the basis of some studies in developed countries critics have complained that a fuel tax would be regressive this paper uses data from a representative household survey covering more than 124 thousand indian households to examine this claim it finds that a fuel tax would be progressive as would a carbon tax using an input output approach it is found that the progressivity results holds good even when one considers indirect consumption of fuel through its use as an intermediate input sensitivity checks allowing for differing price elasticities of demand between rich and poor confirm this result for most of fuels a tax on kerosene is the only fuel tax that is regressive in all situations

woodfuels livelihoods and policy interventions changing perspectives in the 1970s it appeared that fuelwood use was growing rapidly and this could have major adverse impacts on the resource and poor users by the mid 1980s revised assessments indicated that there was less of a problem than had been foreseen and much less of a need for forestry interventions to maintain supplies as a result many of the latter were sharply scaled back additional information and analysis that has become available since the 1980s support the view that there is no need for large scale interventions devoted just to provision of fuelwood however declining access to supplies or markets can raise significant problems in some areas and for particular categories of user growing urban demand for charcoal can also cause local problems in particular in africa the potentials for appropriate forms of intervention are discussed

elasticities in aids models in the literature a variety of approaches have been used to calculate demand elasticities in almost ideal demand system aids models of demand it is common to estimate the linear approximate almost ideal demand system la aids instead of the aids when the la aids is estimated all of the previously reported approaches to compute elasticities are theoretically incorrect this paper presents correct formulas for la aids elasticities and illustrates the potential errors from using incorrect computing the almost ideal demand system aids of deaton and muellbauer 1980a b has become popular in recent years anderson and blundell blanciforti and green 1983a b blanciforti green and king chalfant eales and unnevehr fujii khaled and mak fulponi heien and willett murray parsons ray a variety of approaches to computing elasticities has been used and some of the approaches may lead to significant errors this paper clarifies the differences between alternative approaches to estimating demand elasticities in aids models

assessing the mean reversion behaviour of fiscal policy the perspective of asian countries this article investigates fiscal policy sustainability in 10 asian countries by adopting a battery of unit root tests univariate unit root tests reveal that the fiscal stance in these countries follows a nonstationary process while the opposite conclusion was drawn for the same dataset using the commonly employed panel unit root techniques by utilizing the series specific panel unit root test recently developed by breuer et al 2002 suradf seemingly unrelated regression augmented dickey fuller that allows testing for the presence of nonstationarity within individual cross sections of the panel we found that only cross sections four out of 10 countries in the panel are stationary this means that fiscal deficits in most asian countries are in violation of their intertemporal budget constraint and that the deficits are too large

wage bargaining in the presence of social services and transfers oecd economies were able to reconcile the pursuit of welfare state expansion and full employment during the first decades of the postwar period yet the trade off between these two policy objectives widened in recent decades to explore the question of why this change occurred this article extends familiar models of wage determination by adding a number of parameters that capture cross national differences among welfare states the model identifies the conditions under which unions deliver wage moderation in exchange for social policy benefits and transfers and explores how different labor market institutions magnify or decrease the impact of wage choices on the equilibrium level of employment next the author examines the impact of changes in the composition of social policy expenditures and in the level of the tax burden on unions wage choices she shows that mature welfare states characterized by high tax burdens and a high share of transfers devoted to labor market outsiders reduce the effectiveness of wage moderation in lowering unemployment the author tests the main propositions using oecd panel data for the period 1960 95

fuel food or forest dilemmas in a nepali village abstract field data from a village panchayat in the east nepal hill region demonstrate that deforestation is caused not so much by fuelwood demand as by the need to clear forest areas for food supply the method of analysis uses questionnaire survey participant observation and direct measurements in a micro set up to assess the demand as well as the supply systems of food and fuel and to analyse the impact on deforestation policy implications suggest that to control deforestation food production and distribution practices need to be improved existing forests need to be managed better to increase sustainable fuelwood supply and the direct participation of local people is indispensable to implement desired improvements

urban household energy use in india efficiency and policy implications biomass based fuels are being steadily replaced with modern fossil fuels and electricity in cities of developing countries the latter energy sources are more convenient and efficient to use and produce less local pollutants this fuel transition has accompanied economic growth in many cities empirical data to substantiate these generalizations are being gathered by researchers we report on a recent survey of household energy use in the city of hyderabad india the survey reveals that the underlying fuel transition is consistent with that in other developing country cities government policy however has favored the rich because of the inequities in fuel and equipment availability among income groups we report the major findings of the survey in context of other data for india and suggest policy changes to redress these inequities

politics and business cycles in industrial democracies politics alberto alesina influences from political competition on macroeconomic policy are often thought to be a source of economic fluctuations politicians are described as being driven by two not mutually exclusive main motivations they want to be reelected and they harbour political or ideological biases when such theories are confronted with actual cycles in a number of industrial countries the pattern of inflation unemployment output and budget deficits indicates that partisan policy making is a fairly widespread phenomenon with more limited evidence that electoral preoccupations result in major fluctuations the combination of partisanship and electoral cycles may easily result in socially undesirable outcomes in particular the degree of politico institutional stability and the independence of the central bank have a bearing on macroeconomic outcomes these observations raise a number of important questions about the design of political institutions

the emerging u s current account deficit in the 1980s a cointegration analysis this paper seeks to understand the recent history of u s external imbalances by identifying the long run tendency of the u s current account balance and investigating its behavior the procedure that is adopted is to estimate cointegrating regressions between u s exports and imports of goods and services estimates from cointegrating regressions between several measures of u s exports and imports show that up to about the end of 1983 the u s current account tended toward zero since that time there has been an apparent structural shift resulting in a long run tendency for a deficit in excess of 100 billion per year copyright 1992 by mit press

mean reverting behavior of current account in asian countries abstract this paper adopted the series specific panel unit root test of breuer et al oxford bulletin of economics and statistics 64 2002 suradf 527 546 to test for the mean reverting behavior of current account for the panel of twelve asian countries the results illustrate that the current accounts in these countries are a mixture of i 0 and i 1 process and the commonly used panel root tests could lead to misleading inferences

the intertemporal budget constraint and current account sustainability in cyprus evidence and policy implications using the recently developed bounds testing approach this article provides evidence that cyprus is not in violation of its intertemporal budget constraint and its current account balance is strongly sustainable in the long run a policy implication of these findings is that the loss of exchange rate policy following the adoption of the euro in 2008 may not be a serious cost for cyprus on a methodological level the results presented in this article support theoretical models that employ an intertemporal approach to modelling the current account

financial integration of east asian economies evidence from real interest parity in this article we investigate the financial linkages between the east asian economies with japan and the united states we test for long run real interest rate parity rip using an array of panel data techniques including recent techniques developed by breuer et al 2002 and carrion i silvestre et al 2005 this study offers two important results first the failure to account for structural breaks in the industrialized countries and asian emerging economies is likely to provide evidence of nonstationary series that are stationary second we found strong evidence that the parity condition holds in all the asian countries the failure of earlier studies to confirm mean reversion of real interest rate differential rid may reflect the choice of estimation testing procedure rather than any inherent deficiency in the rip

demand analysis of fresh and frozen finfish and shellfish in the united states household expenditures for at home consumption on three species of shellfish and five species of finfish were analyzed factors explaining the variation of expenditures on seafood commodities were own price household income coupon value household size geographic region urbanization race and seasonality own price elasticities ranged from 0 45 flounder sole to 1 13 oysters expenditures on fishery products were more sensitive to changes in household size than to changes in household income cross price effects of red meat and poultry were not statistically significant for comparison purposes estimates of own price income and household size elasticities from the literature were made with this set of elasticities

the sustainability of india s current account this study conducts an investigation into the sustainability of the indian current account using data for 1950 onwards a necessary condition for current account sustainability is that exports and imports are cointegrated after testing for unit roots that allow for a structural break we employ parametric tests for cointegration based on johansen 1995 and saikkonen and lutkepohl 2000a b c as well as the nonparametric procedure proposed by breitung 2002 and breitung and taylor 2003 that does not assume linearity by employing these procedures recursively two distinct regimes are identified characterized by whether or not imports and exports are cointegrated the regime of noncointegration runs until the late 1990s and the second regime of cointegration is present after that this latter regime coincides with the liberalization of the indian economy
