foreign exchange shocks and gasoline consumption abstract in an open economy the foreign exchange rate fer influences incentives for the cross border shopping of gasoline as well as the opportunity cost of using vehicles and the relative attractiveness of home versus foreign travel using monthly regional level data of gasoline consumption in iran we estimate the impact of exchange rate shocks both in level and volatility on gasoline demand we find that positive exchange rate shocks have a negative impact on total gasoline consumption as well as on vehicle users demand in both short run and long run furthermore we find that in the periods that fer is less volatile the responsiveness of gasoline demand to a change in fer is more pronounced

wheat from chaff meta analysis as quantitative literature review abstract this paper presents and develops a quantitative method of literature reviewing and evaluating empirical research meta regression analysis or mra economics is theory driven yet we must learn empirically if economics is to advance mra offers a more objective statistical method to summarize our empirical knowledge and to explain the wide study to study variation in economic research mra is used to assess the evidence for ricardian equivalence and its findings are contrasted to those of conventional narrative review furthermore mra establishes a platform from which to distinguish genuine empirical effect from the exploitable specification error that infests applied econometrics

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

control and performance of international joint ventures control is a critical concept for successful management and performance of international joint ventures ijvs this paper reviews and synthesizes prior studies addressing the conceptualization and operationalization of control within ijvs as well as the ijv control performance relationship the paper also presents a new conceptualization of ijv control as well as a conceptual frame work for studying control of ijvs

competition cooperation and innovation organizational arrangements for regimes of rapid technological progress abstract discussions of the link between firm size and innovation are outmoded because the boundaries of the firm have become fuzzy in recent decades strategic alliances constellations of bilateral agreements among firms are increasingly necessary to support innovative activities such alliances can facilitate complex coordination beyond what the price system can accomplish while avoiding the dysfunctional properties sometimes associated with hierarchy antitrust law and competition policy need to recognize that these new organizational forms are often the functional antithesis of cartels though they may have certain structural similarities a more complete understanding of bilateral contracts and agreements ought to reveal when and how cooperation can support rather than impede innovation and competition

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

inter firm technology transfer partnership embedded licensing or standard licensing agreements when companies decide to engage in technology transfer through licensing to other firms they have two basic options to use standard licensing contracts or to set up more elaborate partnership embedded licensing agreements we find that broader partnership embedded licensing agreements are preferred with higher levels of technological sophistication of industries with greater perceived effectiveness of secrecy as a means of appropriability and when licensors are smaller than their licensees innovative differentials between companies innovative supremacy of the licensor and market and technological overlap between partners appear to have no effect on the preference for a particular form of licensing

the us retail demand for fish products an application of the almost ideal demand system the main objective is to address the limitations of past us fish demand research through the development of a variation of the almost ideal demand system model for disaggregate fish products at the retail level price and expenditure elasticities as well as elasticities of substitution between fish products and other protein commodities determined from this work may be used in the context of fisheries management and market development and promotion results indicate that with the exception of shellfish demand for the various fish products is relatively inelastic cross price elasticities are generally moderate while expenditure elasticities are large and positive for fresh fish and shellfish demographic effects especially geographical division season race occupation age sex household composition and price income interaction as a proxy for quality are highly significant variables

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

energy demand in ghana a disaggregated analysis this paper presents a comprehensive analysis of energy demand in ghana by estimating demand functions for key disaggregated energy components including gasoline diesel liquefied petroleum gas lpg kerosene biomass residual fuel oil rfo and electricity our results show that energy prices income urbanization and economic structure are significant demand drivers of the different energy types in ghana with varying estimated elasticities further there is evidence of high degree of inter fuel substitution in energy demand in ghana particularly from gasoline diesel and kerosene towards lpg consumption we recommend among different policy options a customization of energy price subsidization policies especially on lpg to reduce the unintended beneficiary dilemma or spillover effect of current government policy other policies such as intensification of energy conservation programs and market entry of independent power trading companies to enhance energy service delivery through competition are also discussed

demand for prepared meals by u s households using the 1987 88 nfcs a heckman two stage procedure was used to estimate the demand for prepared meals by u s households prepared meals were defined as those ready to eat and those ready to cook households headed by younger more educated and time constrained managers were more likely to purchase prepared meals income elasticities ranged from 0 07 to 0 13 while own price elasticities ranged from 0 23 to 0 66 evidence exists to indicate that prepared meals and food away from home are substitutes the presence of teenagers in a household is positively associated with expenditures of prepared meals

price and income elasticities of oil demand in mauritius an empirical analysis using cointegration method abstract there are no studies that quantify the effects of price and income on the demand of fuel oil gasoline and diesel oil in mauritius in line with increasing retail prices for these commodities there is no estimation of the effect that increasing price income and other variables like electricity and vehicle stock have on demand of petroleum products which affects effective policymaking in this area this study uses an ardl ecm model to determine consumer response on petroleum demand when price and income in mauritius changes the study determines the income and price elasticities of demand which is a needed parameter in transportation and taxation policies it was found that gasoline is price and income inelastic in the short run diesel oil is income inelastic in the long run and fuel oil is inelastic in the short run but becomes elastic in the long run other variables being not significant the effect of rising electricity consumption on fuel oil demand was to a ratio of 1 1 1 on average vehicle stock is estimated to cause unprecedented increase in gasoline demand by nearly 3 1 on average results are essential for transportation and energy taxation policymaking

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

demand analysis for fish in indonesia the purpose of this study was to determine an aggregate demand function and the factors influencing the demand for fish in indonesia during the period 1967 88 using a box cox transformation methodology the double log model was found to be appropriate for explaining the demand for fish factors influencing demand were own price price of eggs and per capita income results of static analysis showed an own price of 0 102 a cross price elasticity for eggs of 0 271 and an income elasticity of 0 506 a dynamic analysis using a houthakker taylor model indicated that fish consumption depended on psychological food buying habits of consumers short run and long run elasticities resulting from a partial adjustment model implied that per capita consumption of fish is growing at a slow rate

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

analysis of household attitudes toward the purchase of livestock products and fish in cameroon the need for additional information on household demand for meat and fish in cameroon is addressed probit analysis involving the heckman selectivity correction procedure is used to estimate the effects of individual and household characteristics on demand for beef chicken pork and fish results indicate that fish is a relative necessity in cameroon and is often substituted for beef and chicken by households whose profiles include being of low income levels having large household sizes are of middle age and are less educated whereas chicken and pork substitute each other they are each complementary to beef the profiles of households likely to purchase beef include being married middle age educated and of the muslim faith profiles for households most likely to increase their purchases of chicken include being of high income levels and are public sector employed some policy implications are provided

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

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

estimating the armington elasticity the importance of study design and publication bias abstract a key parameter in international economics is the elasticity of substitution between domestic and foreign goods also called the armington elasticity yet estimates vary widely we collect 3524 reported estimates of the elasticity construct 32 variables that reflect the context in which researchers obtain their estimates and examine what drives the heterogeneity in the results to account for model uncertainty we employ bayesian and frequentist model averaging to correct for publication bias we use newly developed non linear techniques our main results are threefold first there is publication bias against small and statistically insignificant elasticities second differences in results are best explained by differences in data aggregation frequency size and dimension third the elasticity implied by the literature after accounting for both publication bias and study quality lies in the range 2 5 5 1 with a median of 3 8

picture this a simple graph that reveals much ado about research funnel graphs provide a simple yet highly effective means to identify key features of an empirical literature this paper illustrates the use of funnel graphs to detect publication selection bias identify the existence of genuine empirical effects and discover potential moderator variables that can help to explain the wide variation routinely found among reported research findings applications include union productivity effects water price elasticities common currency trade effects minimum wage employment effects efficiency wages and the price elasticity of prescription drugs

determinants of governance structure in alliances the role of strategic task and partner uncertainties research in transaction cost economics and structural sociology has emphasized the role of opportunism and trust in the choice between equity and non equity governance forms in alliances this paper suggests that the uncertainty surrounding partner cooperation is not straightforwardly predictive of governance structure in alliances instead task uncertainty and strategic uncertainty associated with the activities performed within alliances induce coordination and adaptation requirements that are important determinants of alliance governance independently of partner uncertainty support for this view is provided based on a 12 year panel of alliances formed in the us telecommunications entertainment and computer industries

gasoline demand revisited an international meta analysis of elasticities meta analysis is used to determine if there are factors that systematically affect price and income elasticity estimates in studies of gasoline demand four econometric models are estimated using long run and short run price and income elasticity estimates from previous studies as the dependent variables explanatory variables include functional form lag structure time span national setting estimation technique and other features of the model structure elasticity estimates are found to be sensitive to the inclusion or exclusion of some measure of vehicle ownership static models appear to overestimate short run elasticities underestimate long run price elasticities but pick up the full long run income responsiveness there is variation in the elasticity of demand across countries especially in the short run and gasoline demand appears to be getting more price elastic and less income elastic over time

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

beyond publication bias abstract this review considers several meta regression and graphical methods that can differentiate genuine empirical effect from publication bias publication selection exists when editors reviewers or researchers have a preference for statistically significant results because all areas of empirical research are susceptible to publication selection any average or tally of significant insignificant studies is likely to be biased and potentially misleading meta regression analysis can see through the murk of random sampling error and selected misspecification bias to identify the underlying statistical structures that characterize genuine empirical effect meta significance testing and precision effect testing pet are offered as a means to identify empirical effect beyond publication bias and are applied to four areas of empirical economics research minimum wage effects union productivity effects price elasticities and tests of the natural rate hypothesis

partner contributions as predictors of equity share in international joint ventures the type of expertise that a company contributes to a joint venture may affect the amount of equity that it owns this research observes the ownership patterns associated with four common combinations of partner expertise in international joint ventures the results rank company assets with respect to the contributor s ability to negotiate majority ownership in the original joint venture contract and that company s tendency to buy up equity from the partner later on

impacts of oil price shocks on the united states economy a meta analysis of the oil price elasticity of gdp for net oil importing economies policy makers are interested in estimates of the potential economic impacts of oil price shocks particularly during periods of rapid and large increases that accompany severe supply shocks literature estimates of the economic impacts of oil price shocks summarized by the oil price elasticity of gdp span a very wide range due to both fundamental economic and methodological factors this paper presents a quantitative meta analysis of the oil price elasticity of gdp for net oil importing countries with a focus on the united states us the full range of estimates of the oil price elasticity of gdp for the us in the data is 0 124 to 0 017 accounting for different methodologies data and other factors we employ a meta regression model that controls for key determinant factors to estimate the mean and variance of the gdp elasticity across studies we use a robust estimation technique to deal with heterogeneity of the data and well known econometric issues that confront meta analysis the resulting regression model is used to simulate the oil price elasticity of gdp for the us with a mean of 0 020 and 68 confidence interval of 0 035 to 0 006 four quarters after a shock

demand for food commodities by income groups in indonesia an analysis of the structure of demand was performed on household data classified into income groups for urban indonesia a demographically augmented linearized almost ideal demand system was used to estimate the structural parameters of the demand equations endogenous switching regression techniques yielded unbiased and consistent demand parameter estimates for the low income group which had a large number of zeros for some food groups standard seemingly unrelated equation techniques were used to estimate the demand parameters for the other income groups the results showed demands for the medium to high and high income households to be responsive to prices income and demographic variables demands for the medium to low income households were responsive to income and prices only demands for low income households were responsive to income and prices of rice and fish only

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

meta regression analysis a quantitative method of literature surveys abstract pedagogically literature reviews are instrumental they summarize the large literature written on a particular topic give coherence to the complex often disparate views expressed about an issue and serve as a springboard for new ideas however literature surveys rarely establish anything approximating unanimous consensus ironically this is just as true for the empirical economic literature to harmonize this dissonance we offer a quantitative methodology for reviewing the empirical economic literature meta regression analysis mra is the regression analysis of regression analyses mra tends to objectify the review process it studies the processes that produce empirical economic results as though they were any other social scientific phenomenon mra provides a framework for replication and offers a sensitivity analysis for model specification in this brief essay we propose a new method of reviewing economic literature mra and discuss its potential

are all economic facts greatly exaggerated theory competition and selectivity there is growing concern and mounting evidence of selectivity in empirical economics most empirical economic literatures have a truncated distribution of results the aim of this paper is to explore the link between publication selectivity and theory contests this link is confirmed through the analysis of 87 distinct empirical economics literatures involving more than three and a half thousand separate empirical studies using objective measures of both selectivity and contests our meta meta analysis shows that publication selection is widespread but not universal it distorts scientific inference with potentially adverse effects on policy making but competition and debate between rival theories reduces this selectivity and thereby improves economic inference

long run gasoline demand for passenger cars the role of income distribution it is commonly agreed that the level of income and prices are crucial determinants of the consumption of motor gasoline the respective long run price and income elasticities are regularly calculated using cross sectional models despite the acknowledgement of the role of income distribution it plays no role in intercountry cross sectional models this is due to a lack of appropriate data this paper shows that the omission of distributional characteristics provides misleading elasticities using available distributional measures this paper is referring to an income threshold which is crucial to the acquisition of an automobile it is shown that on the one hand in poor countries an unequal income distribution is needed to enable at least some people to buy automobiles on the other hand in wealthy countries an unequal income distribution would exclude some people from acquiring automobiles hence depending on the income level inequality has a diverging impact on the ability to buy durable goods the second part of this paper develops a pooled 90 country model to examine this approach empirically it could be shown that distribution variables are highly significant to explain the demand for automobiles and motor gasoline moreover the consideration of the distribution of income leads to a considerable decrease in income elasticity values this is mainly due to the positive correlation between income level and income equality within the sample

control and performance in international joint ventures the authors examine the meaning of control in international joint ventures ijvs and the relationships of potential means of control in such organizations to the performance satisfaction of the foreign partner they propose a conceptual model that provides both a traditional ownership focused internalization perspective on those issues and an integrated approach combining a broader transaction cost interpretation of control with a resource input based bargaining power model a set of simultaneous structural equations with endogenous explanatory variables provides multiple possible paths from various resource and power inputs through different means of control to perceived performance satisfaction in such a model intermediate variables act both as dependent and independent variables thus the complex theoretical interactions of the variables are modeled more comprehensively and realistically than in single equation models to test the model and compare the theoretical relationships the authors used dat

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

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

the demand for transport fuels in turkey abstract in this paper we estimate the demand for transport fuels in turkey specifically using four different models namely a partial adjustment model a distributed lag model an autoregressive distributed lag model and an error correction model we estimate gasoline and diesel demand functions with quarterly data covering the period 2003 q1 2014 q3 we find a stable long run relationship only for diesel demand income and price our results imply that gasoline demand does not respond to income and price in the long run reflecting a shift from gasoline towards diesel induced by differential tax policies furthermore we find that transport fuel demand is price inelastic making tax on fuel a perfect tool for raising budget revenues in addition our results suggest that fuel demand responds to negative and positive price changes symmetrically

carbon tax incidence on household demand effects on welfare income inequality and poverty incidence in thailand abstract studying the impact of a carbon tax on household demand can be relevant in terms of securing public acceptance of a carbon tax and clarifying the implications for policy design this paper aims to fill a gap in the academic literature by simulating carbon tax scenarios and estimating distributional effects of the tax on household welfare income inequality and poverty rates based on household consumption in thailand the study employs a microsimulation model incorporating the economy wide effects of the tax on prices and consumers behavioral responses to changes in prices the results indicate that a carbon tax is progressive in thailand under revenue recycling scenarios by expanding social transfer programs when carbon tax revenues are recycled through pensions for elderly people the carbon tax could reduce the poverty rate and improve the welfare of households in the lowest quintile the results imply that the distributional impacts of environmental taxes could result in favorable outcomes for income inequality and poverty reduction in developing countries

technological flows and choice of joint ventures in technology alliances abstract this paper analyses the influence of technological flows in the choice of joint ventures as a governance form of technology alliances using a theoretical framework based on transaction costs economics and the economics of intellectual property rights we argue that the formation of a joint venture is only necessary in situations for which technological flows make the monitoring of alliance activities and the distribution of cooperation rents difficult our hypotheses have been confirmed using a sample of technology alliances created by companies from the european union between 1992 and 1999

the rise and fall of small worlds exploring the dynamics of social structure this paper explores the interplay between social structure and economic action by examining some of the evolutionary dynamics of an emergent network that coalesces into a small world system the study highlights the small world system s evolutionary dynamics at both the macro level of the network and the micro level of an individual actor this dual analytical lens helps establish that in competitive and information intensive settings a small world system could be a highly dynamic structure that follows an inverted u shaped evolutionary pattern wherein an increase in the small worldliness of the system is followed by its later decline as a result of three factors 1 the recursive relationship between the evolving social structure and individual actors formation of bridging ties which eventually homogenizes the information space and decreases actors propensity to form bridging ties creating a globally separated network 2 self containment of the small world network or increasing homogenization of the social system which makes the small world less accepting of and less attractive to new actors thereby limiting formation of bridging ties to outside clusters and 3 fragmentation of the small world network or the small world system s inability to retain current clusters the study uses data on interorganizational tie formation in the global computer industry in the period from 1996 to 2005 to test the hypothesized relationships

calculating marginal effects in models for zero expenditures in household budgets using a heckman type correction using the heckamn approach either in single equation or multi equation settings general expressions are derived for calculating marginal effects and elasticities in the conventional calculation of marginal effects terms related to the change in the inverse of mills ratio are omitted using data from the 19877 88 nationwide food consumption survey we calculate income and household size elasticities for 12 food commodities we compare the magnitudes and signs of the elasticities using the conventional expressions of marginal effects and our derived expressions bottomline sizeable differences especially in single equation applications can occur in calculating marginal effects if one fails to account for changes in the inverse of the mills ratio

survey article publication bias in the literature on foreign direct investment spillovers abstract in this article we conduct a large quantitative survey of the literature on horizontal and vertical spillovers from foreign direct investment fdi we create a unique database of spillover estimates for each country examined in the literature next we estimate the average effect corrected for publication selection bias the preferential selection of positive and significant estimates for publication our results suggest that an average reported estimate of backward spillovers is statistically significant publication selection is evident only among studies published in peer reviewed journals and only among the estimates that authors consider most important authors with small data sets engage in more publication selection the intensity of selection in the literature decreases over time which supports the economics research cycle hypothesis

analysing gasoline demand elasticities a survey this paper is a survey of studies on gasoline demand although there are very many dxerent studies in this eld which sometimes appear to arrive at contradictory results we find that with proper stratification of studies by model and data type much of the contict turns to consensus in this survey we classtfy studies by data type and by ten d erent categories of model and with the exception of estimates on seasonal data which tend to be unstable and of certain inappropriate model formulations we find a fair degree of agreement concerning average short run and even long run income and price elasticities

buyer supplier relations in industrial markets when do buyers risk making idiosyncratic investments it is well established that the existence of investments specific to a relationship influences the choice of governance structure including the use of contractual safeguards what is less well understood are the circumstances leading to the creation of those specific assets to begin with this paper explores the industrial buyer s motives to put itself at risk by making investments tangible and intangible which cannot be readily redeployed from one supplier to another using original data from a sample of 388 supply relationships involving all automakers in the u s and japan we examine features of the supply task the supplier and the supply environment which serve as motives to make supplier specific investments we also examine potential factors which facilitate the posting of specific assets as credible commitments to attenuate supplier opportunism we find that specific investments by buyers serve as a mechanism to 1 increase coordination when the manufacturing task is complex 2 buffer the buyer against technological uncertainty and 3 build close relationships when the requisite production skills are scarce the supply market is thin we find more specific investments in supply arrangements that are embedded in a broader business relationship we find fewer supplier specific investments in the japanese context finally we find that buyers focus their investments on lesser known low share component makers perhaps to capitalize on a unique focused supplier capability

how price inelastic is demand for gasoline in fuel subsidizing economies abstract in recent years governments that have historically subsidized domestic fuel consumption face an ever growing challenge in maintaining fuel subsidies and have embarked on subsidy reform this paper estimates the price and income elasticity of demand for gasoline in countries where fuel prices are government subsidized we make use of biennial panel road sector data for 32 countries over the 1998 2010 period and find demand for gasoline to be price inelastic both in the short run and long run we estimate the short run price and income elasticities at 0 05 and 0 16 and the long run price and income elasticities at 0 25 and 0 81 respectively it is our contention that concerned governments should play an active role in identifying and committing to a road map to progressively abandoning fuel subsidies they should also not be discouraged by relatively small consumption corrections in the short run a reduction in subsidies can eventually release considerable amount of resources for more crucial and potentially growth enhancing public services such as education and health

determinants of horizontal spillovers from fdi evidence from a large meta analysis summary the voluminous empirical research on horizontal productivity spillovers from foreign investors to domestic firms has yielded mixed results in this paper we collect 1 205 estimates of spillovers and examine which factors influence spillover magnitude our results suggest that horizontal spillovers are on average zero but that their sign and magnitude depend systematically on the characteristics of the domestic economy and foreign investors foreign investors who form joint ventures with domestic firms and who come from countries with a modest technology edge create the largest benefits for the domestic economy

remittances and economic growth a meta analysis abstract expatriate workers remittances represent an important source of financing for low and middle income countries no consensus however has yet emerged regarding the effect of remittances on economic growth in a quantitative survey of 538 estimates reported in 95 studies we find that approximately 40 of the studies report a positive effect 40 report no effect and 20 report a negative effect our results indicate publication bias in favor of positive effects correcting for the bias using recently developed techniques we find that the mean effect of remittances on growth is still positive but economically small nevertheless our results uncover noticeable regional differences remittances are growth enhancing in asia but not in africa studies that do not control for alternative sources of external finance such as foreign aid and foreign direct investment mismeasure the effect of remittances finally time series studies and studies ignoring endogeneity issues report systematically larger effects of remittances on growth

the application and economic interpretation of selectivity models substantial differences in economic interpretations may be inferred from the estimated selectivity model results using the demand for frozen concentrated orange juice fcoj as an example the study suggests that the consumption patterns are quite similar between national brand and private label when the marginal effects and elasticities are evaluated based on actual observations rather than unobserved latent variables results show that private label fcoj is considered as a normal inferior good if the income effect is assessed based on actual potential purchases the estimated cents off elasticities for private label fcoj also vary substantially depending on which approach is used

how much does trust really matter some reflections on the significance and implications of madhok s trust based approach madhok s 1995 article defined and developed a trust based perspective on the stability of international joint ventures ijvs proposing a shift in focus from ownership to relationship and from governance form to process the article emphasised the role of trust in holding ijvs together and the importance of considering the dynamics of inter organisational collaboration by distinguishing between structural and social components of trust it contributed to a more nuanced understanding of what makes inter firm partnership durable and able to realise its value potential this paper reviews madhok s original ideas and highlights the influence they have had on the field of international business it concludes with avenues for further research inspired by the article

a meta analysis of the price elasticity of gasoline demand a sur approach abstract automobile gasoline demand can be expressed as a multiplicative function of fuel efficiency mileage per car and car ownership this implies a linear relationship between the price elasticity of total fuel demand and the price elasticities of fuel efficiency mileage per car and car ownership in this meta analytical study we aim to investigate and explain the variation in empirical estimates of the price elasticity of gasoline demand a methodological novelty is that we use the linear relationship between the elasticities to develop a meta analytical estimation approach based on a seemingly unrelated regression sur model with cross equation restrictions this approach enables us to combine observations of different elasticities and thus increase our sample size furthermore it allows for a more detailed interpretation of our meta regression results the empirical results of the study demonstrate that the sur approach leads to more precise results i e lower standard errors than a standard meta analytical approach we find that with mean short run and long run price elasticities of 0 34 and 0 84 respectively the demand for gasoline is not very price sensitive both in the short and the long run the impact of a change in the gasoline price on demand is mainly driven by responses in fuel efficiency and mileage per car and to a slightly lesser degree by changes in car ownership furthermore we find that study characteristics relating to the geographic area studied the year of the study the type of data used the time horizon and the functional specification of the demand equation have a significant impact on the estimated value of the price elasticity of gasoline demand

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

consumer choices for quality and sustainability labelled seafood products in the uk there has been a growing interest in recent years in the potential use of product differentiation in seafood products mainly through eco type labelling as a means of promoting and rewarding the sustainable management and exploitation of fish stocks the potential encapsulated by product differentiation has however yet to be tested in the market place within many countries including the uk this paper draws on a study exploring the nature and extent of the response of uk consumers to the introduction of labelled seafood products and explores the potential of product differentiation to promote sustainable fisheries from the results presented in this paper the scale of the effect has been shown to be greater for sustainability and quality forms of product differentiation than the effect generated by any of the other potential labels the origin and mode of production also generated sizeable and significant effects these results suggest that moves underway to implement certification schemes can be justified in support of sustainable fisheries management the important policy implication is that improvement in the supply side management of fisheries will be needed to facilitate more widespread adaptation of certification schemes nonetheless the opportunities for higher premiums and greater market share due to certification will provide additional incentives for the required management improvements

in country we trust national trust and the governance of international r d alliances drawing on a cognitive perspective of trust we propose that the trust towards an alliance partner s country which we call national trust will affect the governance structure used to organize the alliance between the partners we further argue that this effect of national trust is moderated by improved information on the partner firm using a sample of international alliances among firms based in western european countries we find support for the main effect of national trust on alliance governance decisions as well as partial support for an information based moderation

measuring the income elasticity of water demand the importance of publication and endogeneity biases we present the first study that examines the effects of publication selection in the literature estimating the income elasticity of water demand paradoxically more affected by publication selection are the otherwise preferable estimates that control for endogeneity attempting to correct simultaneously for publication and endogeneity biases we find that the mean underlying elasticity is approximately 0 15 or less the result is robust to controlling for more than 30 characteristics of the estimates and accounting for model uncertainty the differences in the reported estimates are systematically driven by differences in the tariff structure regional coverage data granularity and control for temperature

measuring global gasoline and diesel price and income elasticities abstract price and income elasticities of transport fuel demand have numerous applications they help forecast increases in fuel consumption as countries get richer they help develop appropriate tax policies to curtail consumption help determine how the transport fuel mix might evolve and show the price response to a fuel disruption given their usefulness it is understandable why hundreds of studies have focused on measuring such elasticities for gasoline and diesel fuel consumption in this paper i focus my attention on price and income elasticities in the existing studies to see what can be learned from them i summarize the elasticities from these historical studies i use statistical analysis to investigate whether income and price elasticities seem to be constant across countries with different incomes and prices although income and price elasticities for gasoline and diesel fuel are not found to be the same at high and low incomes and at high and low prices patterns emerge that allow me to develop suggested price and income elasticities for gasoline and diesel demand for over one hundred countries i adjust these elasticities for recent fuel mix policies and suggest an agenda of future research topics

income elasticity of gasoline demand a meta analysis abstract in this paper we quantitatively synthesize empirical estimates of the income elasticity of gasoline demand reported in previous studies the studies cover many countries and report a mean elasticity of 0 28 for the short run and 0 66 for the long run we show however that these mean estimates are biased upwards because of publication bias the tendency to suppress negative and insignificant estimates of the elasticity we employ mixed effects multilevel meta regression to filter out publication bias from the literature our results suggest that the income elasticity of gasoline demand is on average much smaller than reported in previous surveys the mean corrected for publication bias is 0 1 for the short run and 0 23 for the long run

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
