the supply of charity services by nonprofit hospitals motives and market structure this article studies provision of charity care by private nonprofit hospitals we demonstrate that in the absence of large positive income effects on charity care supply convex preferences for the nonprofit hospital imply crowding out by other private or government hospitals extending our model to include impure altruism rivalry provides a possible explanation for the previously reported empirical result that both crowding out and income effects on indigent care supply are often weak or insignificant empirical analysis of data for hospitals in maryland provides evidence of rivalry on the supply of charity care

china s energy consumption and sustainable development comparative evidence from gdp and genuine savings this paper employs the structural vector autoregressions framework and the generalized impulse response function to study the long term dynamic relation between china s energy consumption and sustainable economic growth in addition to the conventional economic indicators gdp growth rates genuine savings rates are particularly examined to indicate sustainable economic development results show that the high elasticity of energy consumption dramatically undermines the capacity of china s sustainability in terms of reducing genuine savings rates we also use variance decomposition to calculate relative variance contribution rates in order to identify the most important factor affecting gdp growth as well as genuine savings rates the analysis finds that clean and renewable energy increase the country s genuine savings significantly that is renewable energy consumption promotes sustainable development for both natural and economic societies however increase in traditional solid energy consumption is more likely to benefit only the growth of gdp

energy consumption and economic growth new insights into the cointegration relationship abstract this paper examines the long run relationship between energy consumption and real gdp including energy prices for 25 oecd countries from 1981 to 2007 the distinction between common factors and idiosyncratic components using principal component analysis allows to distinguish between developments on an international and a national level as drivers of the long run relationship indeed cointegration between the common components of the underlying variables indicates that international developments dominate the long run relationship between energy consumption and real gdp furthermore the results suggest that energy consumption is price inelastic causality tests indicate the presence of a bi directional causal relationship between energy consumption and economic growth

the causality relationship between energy consumption and gdp in g 11 countries revisited abstract this paper explores whether energy conservation policies can be implemented in countries with the same level of development that is is restraining energy consumption without compromising economic growth feasible in all industrialized countries a new granger non causality testing procedure developed by toda and yamamoto 1995 journal of econometrics 66 225 250 is applied to re investigate the relationship if any between energy consumption and income in 11 major industrialized countries the results clearly do not support the view that energy consumption and income are neutral with respect to each other except in the case of the united kingdom germany and sweden where a neutral relationship is found bi directional causality in the united states and uni directional running from energy consumption to gdp in canada belgium the netherlands and switzerland are found this indicates that energy conservation may hinder economic growth in the latter five countries further the causality relationship appears to be uni directional but reversed for france italy and japan which implies that in these three countries energy conservation may be viable without being detrimental to economic growth

electricity consumption real gdp causality nexus evidence from a bootstrapped causality test for 30 oecd countries the goal of this paper is to examine any causal effects between electricity consumption and real gdp for 30 oecd countries we use a bootstrapped causality testing approach and unravel evidence in favour of electricity consumption causing real gdp in australia iceland italy the slovak republic the czech republic korea portugal and the uk the implication is that electricity conservation policies will negatively impact real gdp in these countries however for the rest of the 22 countries our findings suggest that electricity conversation policies will not affect real gdp

energy consumption real income and temporal causality results from a multi country study based on cointegration and error correction modelling techniques abstract unlike previous studies on the causal relationship between energy consumption and economic growth this paper illustrates how the finding of cointegration i e long term equilibrium relationship between these variables may be used in testing granger causality based on the most recent johansen s multivariate cointegration tests preceded by various unit root or non stationarity tests we test for cointegration between total energy consumption and real income of six asian economies india pakistan malaysia singapore indonesia and the philippines non rejection of cointegration between variables rules out granger non causality and imples at least one way of granger causality either unidirectional or bidirectionial secondly by using a dynamic vector error correction model we then analyse the direction of granger causation and hence the within sample granger exogeneity or endogeneity of each of the variables thirdly the relative strength of the causality is gauged through the dynamic variance decomposition technique by decomposing the total impact of an unanticipated shock to each of the variables beyond the sample period into proportions attributable to shocks in the other variables including its own in the bivariate system results based on these tools of methodology indicate that while all pair wise relationships shared common univariate integrational properties only relationships for three countries india pakistan and indonesia were cointegrated for these countries temporal causality results were mixed with unidirectional causality from energy to income for india exactly the reverse for indonesia and mutual causality for pakistan the vdcs were not inconsistent with these results and provided us with an additional insight as to the relatively more dominant direction of causation in pakistan simple bivariate vector autoregressive models for the three non cointegrated systems did not indicate any direction of causality significantly in either direction

insurer hospital bargaining negotiated discounts in post deregulation connecticut this paper uses unique data from the state of connecticut to examine discounting patterns in the state s hospital industry for the years following deregulation 1995 1998 the data provide a rare opportunity to study payer level differences in negotiated discounts for hospital services in addition to presenting descriptive evidence on how discounts vary across payers payer types and hospital types this study uses matched revenue data to analyze the economic determinants of discount magnitudes payer size appears to affect bargaining power but the economic significance of the effect is small the data exhibit patterns consistent with a bargaining explanation in which discount magnitudes depend critically on payers abilities to channel patients to hospitals with which favorable discounts have been negotiated

energy consumption and gdp causality relationship in g 7 countries and emerging markets abstract the causality relationship between energy consumption and income is a well studied topic in energy economics this paper studies the time series properties of energy consumption and gdp and reexamines the causality relationship between the two series in the top 10 emerging markets excluding china due to lack of data and g 7 countries we discover bi directional causality in argentina causality running from gdp to energy consumption in italy and korea and from energy consumption to gdp in turkey france germany and japan hence energy conservation may harm economic growth in the last four countries

energy consumption and economic growth evidence from 11 sub sahara african countries abstract the paper examines the causal relationship between energy consumption and economic growth for eleven countries in sub saharan africa using the autoregressive distributed lag ardl bounds test the study finds that energy consumption is cointegrated with economic growth in cameroon cote d ivoire gambia ghana senegal sudan and zimbabwe moreover this test suggests that energy consumption has a significant positive long run impact on economic growth in ghana kenya senegal and sudan granger causality test based on vector error correction model vecm shows bi directional relationship between energy consumption and economic growth for gambia ghana and senegal however granger causality test shows that economic growth granger causes energy consumption in sudan and zimbabwe the neutrality hypothesis is confirmed in respect of cameroon and cote d ivoire the same result of no causality was found for nigeria kenya and togo the result shows that each country should formulate appropriate energy conservation policies taking into cognizance of her peculiar condition

a search theoretic approach to monetary economics the essential function of money is its role as a medium of exchange the authors formalize this idea using a search theoretic equilibrium model of the exchange process that captures the double coincidence of wants problem with pure barter one advantage of the framework described here is that it is very tractable the authors also show that the model can be used to addre ss some substantive issues in monetary economics including the potenti al welfare enhancing role of money the interaction between specializat ion and monetary exchange and the possibility of equilibria with multip le fiat currencies copyright 1993 by american economic association

market structure and prices the responses of hospitals in the uk national health service to competition abstract the internal market reforms to the uk national health service nhs are a model adopted in many health care systems they introduce competition in supply little is known about the impact of these reforms this paper examines the pricing responses of nhs suppliers to competition the incentives of the reformed system are analysed these indicate that prices should differ between buyers and markets these hypotheses are tested using data on spot market transactions between hospitals and health care buyers the results indicate considerable price variability but offer broad support for the hypotheses

does financial development increase energy consumption the role of industrialization and urbanization in tunisia this paper assesses the relationship among energy consumption financial development economic growth industrialization and urbanization in tunisia from 1971 to 2008 the autoregressive distributed lag bounds testing approach to cointegration and granger causality tests is employed for the analysis the result confirms the existence of long run relationship among energy consumption economic growth financial development industrialization and urbanization in tunisia long run bidirectional causalities are found between financial development and energy consumption financial development and industrialization and industrialization and energy consumption hence sound and developed financial system that can attract investors boost the stock market and improve the efficiency of economic activities should be encouraged in the country nevertheless promoting industrialization and urbanization can never be left out from the process of development we add light to policy makers with the role of financial development industrialization and urbanization in the process of economic development

electricity consumption employment and real income in australia evidence from multivariate granger causality tests this paper examines the relationship between electricity consumption employment and real income in australia within a cointegration and causality framework we find that electricity consumption employment and real income are cointegrated and that in the long run employment and real income granger cause electricity consumption while in the short run there is weak unidirectional granger causality running from income to electricity consumption and from income to employment

natural gas consumption and economic growth in pakistan abstract natural gas is a dominant fuel in pakistan it offers the cheapest and a cleaner alternative source of energy this paper examines the relationship of natural gas consumption and economic growth in pakistan we include capital labor and exports in the model with multivariate framework the ardl bounds testing approach to cointegration and innovative accounting approach are employed to investigate the dynamic causality relationships among the variables we find the existence of long run relationship among the variables natural gas consumption capital labor and exports are positively affecting economic growth in pakistan furthermore we support the natural gas consumption led growth hypothesis and suggest that natural gas conservation policies may retard economic growth

a divisible search model of fiat money this paper extends the kiyotaki wright search model of fiat money to allow for divisible money and goods the extension allows me to examine the standard issues in monetary economics such as the neutrality and superneutrality of money by severing the artificial link in the kiyotaki wright model between the money supply and the number of money holders it is shown that money is neutral but not superneutral money growth generates a trading opportunity effect it changes the fraction of different agents in the economy and hence changes the probability with which agents have a successful match in addition money growth has a negative effect on the real money balance that is familiar in walrasian monetary models the balance of the two effects can imply a positive optimal money growth rate

energy consumption and economic growth in china a multivariate causality test this study takes a fresh look at the direction of causality between energy consumption and economic growth in china during the period from 1972 to 2006 using a multivariate cointegration approach given the weakness associated with the bivariate causality framework the current study performs a multivariate causality framework by incorporating capital and labor variables into the model between energy consumption and economic growth based on neo classical aggregate production theory using the recently developed autoregressive distributed lag ardl bounds testing approach a long run equilibrium cointegration relationship has been found to exist between economic growth and the explanatory variables energy consumption capital and employment empirical results reveal that the long run parameter of energy consumption on economic growth in china is approximately 0 15 through a long run static solution of the estimated ardl model and that for the short run is approximately 0 12 by the error correction model the study also indicates the existence of short run and long run causality running from energy consumption capital and employment to economic growth the estimation results imply that energy serves as an important source of economic growth thus more vigorous energy use and economic development strategies should be adopted for china

money and the gains from trade this article studies the role of money in environments where in each meeting there is a double coincidence of real wants traders who meet at random finance their purchases through current production the sale of divisible money or both it is shown that in the absence of valued money if traders have asymmetric tastes for each other s good they produce and exchange socially inefficient quantities with valued money however traders exchange efficient quantities if the asymmetry of tastes is not too large it is shown that the gains from trade in the monetary economy are strictly greater than those in the corresponding barter economy that the friedman rule holds and that the allocation of resources in the monetary economy converges to the allocation in the barter economy as the growth rate of the money supply is increased

financial development and energy consumption in central and eastern european frontier economies this study examines the impact of financial development on energy consumption in a sample of 9 central and eastern european frontier economies several different measures of financial development are examined including bank related variables and stock market variables the empirical results obtained from dynamic panel demand models show a positive and statistically significant relationship between financial development and energy consumption when financial development is measured using banking variables like deposit money bank assets to gdp financial system deposits to gdp or liquid liabilities to gdp of the three stock market variables investigated only one stock market turnover has a positive and statistically significant impact on energy consumption both short run and long run elasticities are presented the implications of these results for energy policy are discussed

financial development investment and economic growth zhenhui xu in this article i use a multivari ate vector autoregressive var approach to examine the effects of permanent financial development on domestic investment and output in 41 countries between 1960 and 1993 the var approach permits the identification of the long term cumulative effects of financial development on the domestic variables by allowing for dynamic interactions among these variables the results reject the hypothesis that financial development simply follows economic growth and has very little effect on it instead there is strong evidence that financial development is important to growth and that investment is an important channel through which financial development affects growth jel e22 e44 e47 016 057 keywords economic growth financial development investment vector auto regression impulse response i introduction interest in the relationship between financial development and economic growth dates back to early this century and has been growing since the 1980s 1 in the literature three views have emerged concerning the potential importance of finance in economic growth the first sees finance as a critical element of growth schumpeter 19113 goldsmith 19691 mckinnon 19733 shaw 1973 fry 1978 1988 bencivenga and smith 1991 king and levine 1993a 1993b in this view services provided by the financial system are essential for growth and a repressed financial system characterized by price distortion undersaving negative or unstable returns on savings and investment and inefficient allocation of savings among competing users impedes growth 2 as the financial system develops households substitute out of unproductive tangible assets raising the total real supply of credit the quantity and quality of investment and thus the rate of economic growth in addition financial development can pro mote technological innovations and productivity growth king and levine 1993a the second view regards finance as a relatively unimportant factor in growth essentially as the handmaiden to industry and commerce robinson 19521 lucas 1988 stern 1989 in this perspective the lack of financial development is simply a manifestation of the lack of demand for financial services as the real sectors of the economy grow the demand for various financial services rises and will thus be met by the financial sector based on this view financial development simply follows economic growth and has very little effect on it like the first one the third view ascribes effects to finance but focuses on its potential negative impacts on growth van wijnbergen 1983 buffie 1984 economists holding this view contend that financial development can hinder growth by reducing available credit to domestic firms this situation arises from the presence of informal curb markets as the formal financial system develops households are seen to substitute out of curb market loans thus reducing the total real supply of domestic credit the reduction in the supply of credit can lead to a credit crunch thereby lowering investment and slowing production and growth further such a credit crunch can retard economic growth beyond the short term by lowering the steady state capital stock wijnbergen 1983 from these divergent views three testable hypotheses emerge with sharply different policy implications the first view suggests that government policies should be directed toward improving the financial system since financial development has important causal effects on growth the second view implies that government policies toward improving the financial system will have little effect on growth since financial development results from growth and has little impact on it based on the third view there is a potential danger of financial development under certain institutional arrangements government efforts toward financial development can cost an economy its long term growth by reducing total real supply of domestic credit

multivariate granger causality between electricity consumption exports and gdp evidence from a panel of middle eastern countries this paper examines the causal relationship between electricity consumption exports and gross domestic product gdp for a panel of middle eastern countries we find that for the panel as a whole there are statistically significant feedback effects between these variables a 1 per cent increase in electricity consumption increases gdp by 0 04 per cent a 1 per cent increase in exports increases gdp by 0 17 per cent and a 1 per cent increase in gdp generates a 0 95 per cent increase in electricity consumption the policy implications are that for the panel as a whole these countries should invest in electricity infrastructure and step up electricity conservation policies to avoid a reduction in electricity consumption adversely affecting economic growth further policy implications are that for the panel as a whole promoting exports particularly non oil exports is a means to promote economic growth and that expansion of exports can be realized without having adverse effects on energy conservation policies

energy consumption and economic growth in china a reconciliation abstract in conventional causality testing based on asymptotic distribution theory there is a high risk of wrongly rejecting the true null of no causality especially when the sample size is as small as typically seen in the literature in this study we offer a formal diagnosis of the existing contradictory results on the causal relationship between energy consumption and real gdp we also employ a time series oriented advanced data generation process to perform simulation based inference for the people s republic of china our study covers the 1971 2007 period and considers five different aggregated and disaggregated energy consumption measures as well as three different lag orders in both a bivariate as well as a multivariate frameworks our maximum entropy bootstrap based analysis which avoids pretest biases and is also robust to type i errors supports the neutrality hypothesis in 53 out of the total of 60 model estimations the strong results show that coarse aggregate data has a limited potential to observe the complex causal linkages between energy consumption and economic growth future policy oriented research on this nexus requires more focused analyses based on sectoral and provincial data

the dynamic links between energy consumption economic growth financial development and trade in china fresh evidence from multivariate framework analysis abstract this study investigates the relationship between energy use and economic growth by incorporating financial development international trade and capital as important factors of production function in case of china over the period of 1971 2011 the ardl bounds testing approach to cointegration was applied to examine long run relationship among the series while stationarity properties of the variables was tested by applying structural break test our empirical evidence confirmed long run relationship among the variables the results showed that energy use financial development capital exports imports and international trade have positive impact on economic growth the granger causality analysis revealed that unidirectional causal relationship running from energy use to economic growth financial development and energy use granger cause each other there is bidirectional causality between international trade and energy use the feedback relation exists between financial development and international trade there is also bidirectional causality exists between capital and energy demand financial development and economic growth and international trade and economic growth this paper makes significant contribution in energy economics and opens up new direction for policy makers to explore new and alternative sources of energy which would be helpful in meeting the rising demand of energy due to sustained rate of economic growth

energy and economic growth in the usa a multivariate approach abstract this paper examines the causal relationship between gdp and energy use for the period 1947 90 in the usa the relationship between energy use and economic growth has been examined by both biophysical and neoclassical economists in particular several studies have tested for the presence of a causal relationship in the granger sense between energy use and economic growth however these tests do not allow a direct test of the relative explanatory powers of the neoclassical and biophysical models a multivariate adaptation of the test vector autoregression var does allow such a test a var of gdp energy use capital stock and employment is estimated and granger tests for causal relationships between the variables are carried out although there is no evidence that gross energy use granger causes gdp a measure of final energy use adjusted for changing fuel composition does granger cause gdp

dynamic modelling of energy consumption capital stock and real income in g 7 countries abstract this paper applies an aggregate production function to examine the dynamic linkages among energy consumption capital stock and real income real gdp per capita in g 7 counties we employ the toda and yamamoto 1995 granger causality test the generalized impulse response approach and variance decompositions in a multivariate setting to uncover the extent and the magnitude of the relationship among variables our empirical results find evidence of a unidirectional relationship running from energy consumption to real income in canada italy and the uk indicating that energy conservation may hinder economic growth in the three countries furthermore the causality relationship appears to be unidirectional but reversed for france and japan implying that energy conservation in both countries may still be viable but without being detrimental to economic growth as to germany and the u s there is no causality between the variables which demonstrates the neutrality hypothesis and in such a case economic growth will not affect energy use we further see that the impact of capital stock is relatively higher compared with that of energy consumption transitory initial impacts of innovations in energy consumption on capital stock and real income are observed

the relationship between energy and gnp further results this paper reexamines the casuality between gnp and energy consumption by using updated us data for the period 1947 1979 as a secondary contribution we investigate the causal relationship between energy consumption and employment applying sims technique we find no causal relationship between gnp and energy consumption we find further that there is a slight unidirectional flow running from employment to energy consumption economic interpretations of the empirical results are also presented

competition and efficiency in the end stage renal disease program abstract estimated coefficients for medical service production or cost functions are subject to a competitive amenity bias which may result in the failure to identify factors that affect economic efficiency our investigation of productivity of dialysis facilities did indeed indicate both the likelihood of bias and some qualitative results these results suggest that it will be difficult to estimate cost and that variation in the level of reimbursement will in competitive markets affect the level of amenity delivered to patients incurred cost amenity and patient well being will all vary positively with the reimbursement level determining the right level of reimbursement requires a policy decision on how much total amenity society wishes to deliver to beneficiaries of public programs

on the efficiency of monetary exchange how divisibility of money matters abstract we use alternative assumptions about the divisibility of goods and money and the ability of agents to use lotteries on money to investigate to what extent the indivisibility of money is the cause for the typically inefficient production and consumption decisions in search theoretic models of money our framework potentially generates three types of inefficiencies the no trade inefficiency where no trade takes place even though it would be socially efficient to trade and the too much trade and too little trade inefficiencies where the quantities produced and exchanged are either larger or smaller than what the solution to a social planner s problem would mandate it is shown that while the no trade and the too much trade inefficiencies are caused by the indivisibility of money the too little trade inefficiency remains even when money is divisible unless it is sufficiently valued

managed care s price bargaining with hospitals research has shown that managed care mc slowed the rate of growth in health care spending in the 1990s primarily via lower unit prices paid however the mechanism of mc s price bargaining has not been well studied this article uses a unique panel dataset with actual hospital prices in massachusetts between 1994 and 2000 to examine the sources of mc s bargaining power i find two significant determinants of price discounts first plans with large memberships are able to extract volume discounts across hospitals second health plans that are more successful at channeling patients can extract greater discounts patient channeling can add to the volume discount that plans negotiate

foreign direct investment and decoupling between energy and gross domestic product in developing countries on a sample of 20 developing countries we noticed a clear decline in the energy intensity as foreign direct investment increases the reason for that probably is the use of modern technologies that came with foreign direct investment i e a leapfrogging over the old fashioned traditional technologies in use in these countries

a multivariate cointegration analysis of the role of energy in the us macroeconomy abstract this paper extends my previous analysis of the causal relationship of gdp and energy use in the usa in the post war period a majority of the relevant variables are integrated justifying a cointegration analysis the results show that cointegration does occur and that energy input cannot be excluded from the cointegration space the results are plausible in terms of macroeconomic dynamics the results are similar to my previous granger causality results and contradict claims in the literature based on bivariate models that there is no cointegration between energy and output

what goes up recent trends in china s energy consumption since 1996 china s energy output has dropped by 17 while primary energy use has fallen by 4 driven almost entirely by shrinking output from coal mines and declining direct use since china is the world s second largest emitter of greenhouse gases it is important to understand the sources of this apparent transformation and whether it portends a permanent change in patterns of energy use this remarkable reversal of the long term expansion of energy use has occurred even as the economy has continued to grow albeit more slowly than in the early 1990s generation of electric power has risen implying a steep fall in end uses particularly in industry available information points to a variety of forces contributing to this phenomenon including rapid improvements in coal quality structural changes in industry shutdowns of factories in both the state owned and non state segments of the economy improvements in end use efficiency and greater use of gas and electricity in households a combination of slowing economic growth industrial restructuring broader economic system reforms and environmental and energy efficiency policies has apparently led to at least a temporary decline in and perhaps a long term reduction in the growth of energy use and therefore greenhouse gas emissions

monopoly monopsony and contestability in health insurance a study of blue cross plans i introduction blue cross and blue shield plans the plans have historically occupied a unique niche in health care pauly 1987 notes that the plans serve both as sellers of health insurance and as buyers of health services marmor 1991 described the plans development of health insurance concepts in the 1930s their role as innovators permitted them to occupy a dominant market share position in most geographic areas as a result blair ginsburg and vogel 1975 believe they have traditionally received favorable regulatory treatment including non profit organization status and exemption from taxation potentially the plans have dual market power 1 monopoly power in the market for health insurance and monopsony power in the market for health services this may result in operating inefficiencies and may produce adverse welfare consequences monopsony theory posits that the plans will reduce payments to providers and may stifle innovation in the market for health services this occurs as the result of the plans dominant market shares generated from the fact that they were often the first in the market for insurance and from their ability to enforce a credible threat to reduce providers business should providers refuse to provide reduced cost services the plans dominant market share and their advantage in the market for health services permit them to maintain a competitive advantage in the market for health insurance 2 monopoly theory suggests that the plans advantage in the market for medical services due to regulatory and tax advantages will cause them to i raise premium prices ii sell only a limited range of health insurance policies iii offer policies with more complete coverage than consumers demand 3 iv reduce innovation in the health insurance market and v demonstrate unduly high administrative costs in the 1970s empirical work supported these predictions however the 1980s has been an era of growth of competition and the potential for even more competition in the market for health insurance baumol panzar and willig 1982a noted that a credible threat of entry can produce competitive market conditions in a concentrated market resulting in reduced prices increased quantity and more efficient administrative cost structures if pauly is correct that there are no inherent scale economies in the health insurance market and if the market for health insurance is contestable the plans will pass advantages along to subscribers as reduced premiums and will tolerate fewer administrative cost inefficiencies accordingly the plans present an opportunity to study market structure and its impact in both the market for health care and the market for health care insurance to date no study has evaluated this interplay greater understanding of these interactions is important not only to deal with the phenomena of the plans for instance more appropriate regulatory policies but also to refine the single payer debate and to consider operating standards for health alliances and health plans included in the administration s health care reform package outlined by the white house domestic policy council 1993 section ii of this paper evaluates prior studies of the plans section iii motivates the model for plan behavior section iv describes the results of our empirical study of the plans premium pricing provider payment and administrative costs section v contains our conclusions ii prior studies of plan behavior a number of prior studies have evaluated the plans unique position in the market for health insurance and in the market for health care most focus on the plans monopsony power and payments to providers most important they evaluate markets that have gone through substantial change as health maintenance organizations and preferred provider organizations hmos and ppos have replaced fee for service plans several assess market power and administrative costs

how many times again will we examine the energy income nexus using a limited range of traditional econometric tools during the last three decades following closely the developments in econometric theory energy and environmental economists have empirically examined the energy income nexus for different countries and time periods however today in spite of the growing interest in this area the state of knowledge is still controversial and unsettled this viewpoint paper attempts to highlight some of the issues related to the existing literature on the long run relationship and causality between energy consumption and economic growth in particular it discusses how it is difficult to make policy recommendations on the basis of inconsistent and conflicting results in the published literature on the subject in order to do so the paper first illustrates the increasing trend in the number of studies published in this area providing also a brief comparison of the conventional methods used to estimate the energy income nexus it then deals with new directions and different viewpoints on the same issue

post independence india a case of finance led industrialization abstract this paper examines whether financial intermediaries have played a leading role in influencing india s economic performance after describing the evolution and functions of the financial sector we construct a set of vector autoregressive var and vector error correction models vecm to evaluate the strength and direction of the links between measures of formal intermediation and various economic aggregates the results suggest that i the financial sector was instrumental in promoting aggregate investment and output but also in the steady shift toward industry that has characterized india s development ii the operative channel was one of debt accumulation rather than improvements in total factor productivity and iii its contributions went beyond the passive support of fiscal policy

a unified framework for monetary theory and policy analysis search theoretic models of monetary exchange are based on explicit descriptions of the frictions that make money essential however tractable versions of these models typically make strong assumptions that render them ill suited for monetary policy analysis we propose a new framework based on explicit micro foundations within which macro policy can be studied the framework is analytically tractable and easily quantifiable we calibrate the model to standard observations and use it to measure the cost of inflation we find that going from 10 percent to 0 percent inflation is worth between 3 and 5 percent of consumption much higher than previous estimates

the impact of financial development on energy consumption in emerging economies abstract financial development is often cited as a very important driver of economic growth in emerging economies and it is thus likely that financial development affects energy demand this study uses generalized method of moments estimation techniques to examine the impact of financial development on energy consumption in a sample of emerging countries several different measures of financial development are examined using a panel data set on 22 emerging countries covering the period 1990 2006 the empirical results show a positive and statistically significant relationship between financial development and energy consumption when financial development is measured using stock market variables like stock market capitalization to gdp stock market value traded to gdp and stock market turnover the implications of these results for energy policy are discussed

does higher economic and financial development lead to environmental degradation evidence from bric countries abstract a vast number of studies addressed the environmental degradation and economic development but not financial development moreover as argued by stern 2004 the rise and fall of the environmental kuznets curve world development 32 1419 1439 they present important econometric weaknesses using standard reduced form modeling approach and controlling for country specific unobserved heterogeneity we investigate the linkage between not only economic development and environmental quality but also the financial development panel data over period 1992 2004 is used we find that both economic and financial development are determinants of the environmental quality in bric economies we show that higher degree of economic and financial development decreases the environmental degradation our analysis suggests that financial liberalization and openness are essential factors for the co 2 reduction the adoption of policies directed to financial openness and liberalization to attract higher levels of r d related foreign direct investment might reduce the environmental degradation in countries under consideration in addition the robustness check trough the inclusion of us and japan does not alter our main findings

a contribution to the pure theory of money abstract this article analyzes a general equilibrium model with search frictions and differentiated commodities because of the many differentiated commodities barter is difficult in that it requires a double coincidence of wants and this provides a medium of exchange role for fiat currency we prove the existence of equilibrium with valued fiat money and show it is robust to certain changes in the environment rate of return dominance liquidity and the welfare implications of fiat money are discussed

energy consumption and economic growth the experience of african countries revisited abstract the aim of this paper is to re examine the causal relationship between energy consumption and economic growth for seventeen african countries in a multivariate framework by including labor and capital as additional variables we apply the variance decomposition analysis due to pesaran and shin pesaran m h and shin y generalised impulse response analysis in linear multivariate models economics letters 1998 58 17 29 to evaluate how important is the causal impact of energy consumption on economic growth relative to labor and capital the results of our multivariate modified granger causality analysis due to toda and yamamoto toda h y and yamamoto t statistical inference in vector autoregressions with possibly integrated process journal of econometrics 1995 66 225 250 tend to reject the neutrality hypothesis for the energy income relationship in fifteen out of the seventeen countries in contrast results of our variance decomposition analyses show that in eleven out of the seventeen countries energy is no more than a contributing factor to output growth and not an important one when compared to capital and labor labor and capital are the most important factors in output growth in fifteen out of the seventeen countries however these results should be interpreted with care as they may not be sufficiently robust enough to support the inference that energy consumption plays a minor role in the economic growth of african countries

the effects of market structure and bargaining position on hospital prices ppos and hmos have gained widespread acceptance due in part to the belief that excess capacity and competitive market conditions can be leveraged to negotiate lower prices with health care providers we investigated prices obtained in different types of markets by the largest ppo in california our findings indicate that greater hospital competition leads to lower prices furthermore as the importance of a hospital to the ppo in an area increases the price rises substantially our testing of alternative methods for defining hospital geographic markets reveals that the common practice of using counties to define the market leads to an underestimate of the price increasing effects of a merger

friedman meets hosios efficiency in search models of money this article studies optimal monetary policy in an economy with endogenous search decisions we show that the same frictions that give fiat money a positive value generate an inefficient quantity of goods in each trade and an inefficient number of trades the friedman rule eliminates the first inefficiency and the hosios rule the second a monetary equilibrium attains the social optimum if and only if both rules are satisfied when they cannot be satisfied simultaneously optimal monetary policy achieves only the second best we analyse the conditions under which the second best monetary policy exceeds the friedman rule

liquidity a new monetarist perspective this essay surveys the new monetarist approach to liquidity work in this literature strives for empirical and policy relevance plus rigorous foundations questions include what is liquidity is money essential in achieving desirable outcomes which objects can or should serve in this capacity when can asset prices differ from fundamentals what are the functions of commitment and collateral in credit markets how does money interact with credit and intermediation what can and should monetary policy do the research summarized emphasizes the micro structure of frictional transactions and studies how institutions like monetary exchange credit arrangements or intermediation facilitate the exchange process

retesting the causality between energy consumption and gdp in china evidence from sectoral and regional analyses using dynamic panel data abstract the increasing attention on energy policy needs has provided a renewed stimulus to research the linkages between energy consumption and economic performance in china this paper examined the causal relationship between energy consumption and economic growth in the regional and sectoral aspects by adopting provincial panel data in china from 1995 to 2008 the results indicate that economic growth causes more energy consumption in china not only at the national level but also at the regional and sectoral levels then the eastern region and the industrial sector show results quite similar to that of the whole country in which a bidirectional causality relationship exists between energy consumption and economic growth the implication for energy policies in china is that the eastern region and the industrial sector should play a leading role in the adjustment of energy consumption patterns and the transformation of the economy structure energy prices have limited effects on energy consumption but do have effects on economic growth because the energy price mechanism is more government oriented than market oriented in china

energy consumption and economic growth evidence from china at both aggregated and disaggregated levels using a neo classical aggregate production model where capital labor and energy are treated as separate inputs this paper tests for the existence and direction of causality between output growth and energy use in china at both aggregated total energy and disaggregated levels as coal oil and electricity consumption using the johansen cointegration technique the empirical findings indicate that there exists long run cointegration among output labor capital and energy use in china at both aggregated and all three disaggregated levels then using a vec specification the short run dynamics of the interested variables are tested indicating that there exists granger causality running from electricity and oil consumption to gdp but does not exist granger causality running from coal and total energy consumption to gdp on the other hand short run granger causality exists from gdp to total energy coal and oil consumption but does not exist from gdp to electricity consumption we thus propose policy suggestions to solve the energy and sustainable development dilemma in china as enhancing energy supply security and guaranteeing energy supply especially in the short run to provide adequate electric power supply and set up national strategic oil reserve enhancing energy efficiency to save energy diversifying energy sources energetically exploiting renewable energy and drawing out corresponding policies and measures and finally in the long run transforming development pattern and cut reliance on resource and energy dependent industries

energy use and output growth in canada a multivariate cointegration analysis using a neo classical one sector aggregate production technology where capital labor and energy are treated as separate inputs this paper develops a vector error correction vec model to test for the existence and direction of causality between output growth and energy use in canada using the johansen cointegration technique the empirical findings indicate that the long run movements of output labor capital and energy use in canada are related by two cointegrating vectors then using a vec specification the short run dynamics of the variables indicate that granger causality is running in both directions between output growth and energy use hence an important policy implication of the analysis is that energy can be considered as a limiting factor to output growth in canada

a literature survey on energy growth nexus abstract this paper provides a survey of the recent progress in the literature of energy consumption economic growth and electricity consumption economic growth causality nexus the survey highlights that most empirical studies focus on either testing the role of energy electricity in stimulating economic growth or examining the direction of causality between these two variables although the positive role of energy on growth has become a stylized fact there are some methodological reservations about the results from these empirical studies a general observation from these studies is that the literature produced conflicting results and there is no consensus neither on the existence nor on the direction of causality between energy consumption electricity consumption and economic growth as a policy implication to avoid from conflicting and unreliable results the authors may use the autoregressive distributed lags bounds test two regime threshold co integration models panel data approach and multivariate models including new variables such as real gross fixed capital formation labor force carbon dioxide emissions population exchange rates interest rates etc thus the authors should focus more on the new approaches and perspectives rather than by employing usual methods based on a set of common variables for different countries and different intervals of time

the saving and investment nexus for china evidence from cointegration tests the saving and investment nexus as postulated by feldstein and horioka fh 1980 is revisited the saving investment correlation for china is estimated over the periods 1952 1998 and 1952 1994 the latter culminating in a period of fixed exchange rate regime amongst the key results it is found that saving and investment are correlated for china for both the period of the fixed exchange rate and the entire sample period with high saving investment correlation the results suggest that the chinese economy is in conformity with the fh hypothesis this is a valid outcome for in china capital mobility was fairly restricted over the 1952 1994 period as indicated by the relatively low foreign direct investment
