financial development and energy consumption evidence from a heterogeneous panel of asian countries abstract this paper examined relationships between financial development and energy consumption in asia for the period of 1980 2012 for the purpose of the empirical analysis it performed the heterogeneous panel causality test suggested by dumitrescu and hurlin 1 the findings of the panel cointegration test indicated that there was a long run equilibrium relationship between finance and energy consumption in the region moreover the heterogeneous panel causality test detected a unidirectional causality from energy consumption to financial development but not vice versa these results indicate that an expansion of energy usage could be a driving force behind financial development in asia

the nexus between financial development and energy consumption in the eu a dynamic panel data analysis abstract the relationship between financial development and energy consumption has newly started to be discussed in energy economics literature this paper investigates this issue in the eu over the period 1990 2011 by using system gmm model no significant relationship is found in the eu27 the empirical results however provide strong evidence of the impact of the financial development on energy consumption in the old members greater financial development leads to an increase in energy consumption regardless of whether financial development stems from banking sector or stock market by contrast we find for the new members that the impact of financial development on energy consumption depends on how financial development is measured using bankindex the impact of financial development displays an inverted u shaped pattern while no significant relationship is detected once it is measured using stockindex

capacity allocation ordering and pricing decisions in a supply chain with demand and supply uncertainties abstract this paper studies coordinated decisions in a decentralized supply chain that consists of one original equipment manufacturer oem one manufacturer and one distributor and possesses uncertainties at both demand and supply sides these uncertainties emerge respectively from random demand the distributor faces and randomness of capacity with which the oem processes the manufacturer s outsourced quantity sharing supply and demand uncertainty information along the supply chain enables us to develop three models with different coordination efforts the oem and manufacturer coordination the manufacturer and distributor coordination and the oem manufacturer and distributor coordination and quantify the coordinated decisions in these three models our analysis of these coordination models suggests that coordinating with the oem improves the manufacturer s probability of meeting downstream demand and his expected profit yet coordinating with the manufacturer is not necessarily beneficial to the oem when downstream coordination is lacking

electricity consumption and economic growth nexus in bangladesh revisited evidences abstract in this paper an attempt is being made to examine the causal relationship between per capita electricity consumption and per capita gdp of bangladesh using the vector error correction specified granger causality test to search their short run long run and joint causal relationships for the period of 1971 2008 empirical findings reveal that there is a short run unidirectional causal flow running from per capita electricity consumption to per capita gdp without feedback the presence of a positive short run causality explains that an increase in electricity consumption directly affects economic activity in bangladesh likewise results from joint causality exhibit the same as in short run by contrast long run results show a bi directional causality running from electricity consumption to economic growth with feedback these findings can provide essential policy insights to design immediate and long term growth prospect for bangladesh keeping in mind its present planned growth strategy and dismal power and energy sector

future demand scenarios of bangladesh power sector abstract data on the future electricity demand is an essential requirement for planning the expansion of a power system the purpose of this study is to provide a general overview of electricity consumption in bangladesh forecast sector wise electricity demand up to 2035 considering the base year 2005 and compare the results with official projections the long range energy alternative planning leap model with three scenarios namely low gross domestic product gdp growth average gdp growth and high gdp growth is applied in this study in the low to high gdp growth scenarios the extent of industrial restructuring and technical advancement is gradually increased the findings have significant implications with respect to energy conservation and economic development the study also compares the projected per capita electricity consumption in bangladesh with the historical growth in several other developing countries such an evaluation can create awareness among the planners of power system expansion in bangladesh to meet the high future demand

regime switching effect of financial development on energy intensity evidence from markov switching vector error correction model abstract studies that deal with financial development and energy intensity usually show the single effect of one variable on another or the causality running between them during the whole sample period but this study is an attempt to explore the regime switching effect of financial development on energy intensity in different periods within the sample using yearly data from 1972 to 2017 in case of bangladesh a markov switching vector error correction model is applied to carry out the study and the results reveal a two regime switching nature of the effect of financial development on energy intensity financial development plays a stimulating role in regime 1 where it plays an inhibiting role in regime 2 to influence energy intensity the duration of regime 1 is longer than that of regime 2 specifying that the promoting effect of financial development on energy intensity is more enduring than the inhibiting effect in bangladesh the results have important policy implications to formulate energy policy and to maintain a balance between financial development and energy intensity in bangladesh and other emerging nations

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

exploring the depth of energy penetration in economic advancement perspective of bangladesh abstract developing countries consume a tiny share of world commercial energy this tempts policymakers in developing countries to sort out ways to increase commercial energy demand so that their invaluable resources are best utilized country like bangladesh may fall in trap if quickly declining and immensely valuable energy is wasted in unsustainable growth this urges for better use of its scarce resources for sustainable growth in this paper we aim to identify how energy consumption in bangladesh is related to various growth indicators like national income financial development industrialization and urbanization in the long run in search of a right path for sustainable development in this study we try to assess the relationship among energy consumption financial development economic growth industrialization and urbanization from 1980 to 2010 a number of cointegration techniques are employed to examine whether there is a long run relationship besides these we also employed augmented granger causality test to examine the causality if presents this study finds that financial development economic growth industrialization and urbanization have positive impact on energy consumption in short run but industrialization has no impact in the long run our causality test ensures that the above mentioned variables granger cause energy consumption for sustainable growth industrialization should be given priority as future consumption of energy in industrial sector will be greater than any other sector this future demand can only be fulfilled by injecting more and more renewable energy through solar wind and other technology as nonrenewable energy are declining quickly

managing channel profits a channel of distribution consists of different channel members each having his own decision variables however each channel member s decisions do affect the other channel members profits and as a consequence actions a lack of coordination of these decisions can lead to undesirable consequences for example in the simple manufacturer retailer consumer channel uncoordinated and independent channel members decisions over margins result in a higher price paid by the consumer than if those decisions were coordinated in addition the ensuing suboptimal volume leads to lower profits for both the manufacturer and the retailer this paper explores the problems inherent in channel coordination we address the following questions what is the effect of channel coordination what causes a lack of coordination in the channel how difficult is it to achieve channel coordination what mechanisms exist which can achieve channel coordination what are the strengths and weaknesses of these mechanism what is the role of nonprice variables e g manufacturer advertising retailer shelf space in coordination does the lack of coordination affect normative implications from in store experimentation can quantity discounts be a coordination mechanism are some marketing practices actually disguised quantity discounts we review the literature and present a simple formulation illustrating the roots of the coordination problem we then derive the form of the quantity discount schedule that results in optimum channel profits this article was originally published in marketing science volume 2 issue 3 pages 239 272 in 1983

the dynamics of natural gas consumption and gdp in bangladesh abstract reserves of natural gas in bangladesh are very large and total demand has increased secularly in recent years this paper examines the causal relationship between the consumption of natural gas and gdp in bangladesh over the period 1980 to 2010 we find that there is a positive unidirectional causality running from gdp to natural gas consumption movements in gdp affect the consumption of natural gas but not vice versa while our results rest on several statistical assumptions they support the pursuit of policies that are in line with energy conservation implementing these policies will be of particular significance in light of the fact that bangladesh s current reserves of natural gas will not meet its current level of consumption demand beyond the next two decades

causality relationship between electricity consumption and gdp in bangladesh in this paper we examine the causal relationship between the per capita electricity consumption and the per capita gdp for bangladesh using cointegration and vector error correction model our results show that there is unidirectional causality from per capita gdp to per capita electricity consumption however the per capita electricity consumption does not cause per capita gdp in case of bangladesh the finding has significant implications from the point of view of energy conservation emission reduction and economic development

supply chain coordination with downstream operating costs coordination and investment to improve downstream operating efficiency abstract we endow the downstream firm in a supply chain with operating costs in addition to the traditional overage and underage costs we reanalyze lariviere and porteus s selling to a newsvendor model 2001 allowing for non linear production costs and provide comparative statics we then explore investment in reducing downstream operating costs to overcome the fact that investment is lower in a decentralized chain than in an integrated one we propose several coordination mechanisms buybacks revenue sharing and operating subsidy with a license fee

competition and outsourcing with scale economies scale economies are commonplace in operations yet because of analytical challenges relatively little is known about how firms should compete in their presence this paper presents a model of competition between two firms that face scale economies i e each firm s cost per unit of demand is decreasing in demand a general framework is used which incorporates competition between two service providers with price and time sensitive demand a queuing game and competition between two retailers with fixed ordering costs and pricesensitive consumers an economic order quantity game reasonably general conditions are provided under which there exists at most one equilibrium with both firms participating in the market we demonstrate in the context of the queuing game that the lower cost firm in equilibrium may have a higher market share and a higher price an enviable situation we also allow each firm to outsource their production process to a supplier even if the supplier s technology is no better than the firms technology and the supplier is required to establish dedicated capacity so the supplier s scale can be no greater than either firm s scale we show that the firms strictly prefer to outsource we conclude that scale economies provide a strong motivation for outsourcing that has not previously been identified in the literature

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

discount pricing decisions in distribution channels with price sensitive demand abstract in this paper we evaluate the effectiveness of quantity discounts and volume discounts as coordination mechanisms in distribution channels with demand that is price sensitive we consider a single vendor single retailer distribution channel demand for the product arises only at the retailer the demand faced by the retailer is assumed to be deterministic but price elastic the retailer in turn buys the product from the vendor the vendor and the retailer act independently and rationally each maximizing their own respective profit the equilibrium point that specifies the vendor s and buyer s inventory and pricing policy is determined by the solution to a stackelberg game we consider the cases when quantity discount and volume discount respectively are offered we develop methods to determine the optimal discount policy for these cases we then consider the case where both volume and quantity discounts are offered simultaneously and develop a method to determine the optimal simultaneous discount offer the relative performance of the alternative discount schemes is then evaluated through a numerical study the results of the study demonstrate that the effectiveness of volume discount as a coordination mechanism is higher when the sensitivity of demand to price changes is higher the effectiveness of quantity discount on the other hand is higher with lower price sensitivity of demand finally the results also demonstrate that perfect coordination is achieved when volume and quantity discounts are offered simultaneously

the impact of growth energy and financial development on the environment in china a cointegration analysis this article aims to investigate the impact of financial development economic growth and energy consumption on environmental pollution in china from 1953 to 2006 using the autoregressive distributed lag ardl bounds testing procedure the main objective is to examine the long run equilibrium relationship between financial development and environmental pollution the results of the analysis reveal a negative sign for the coefficient of financial development suggesting that financial development in china has not taken place at the expense of environmental pollution on the contrary it is found that financial development has led to a decrease in environmental pollution it is concluded that carbon emissions are mainly determined by income energy consumption and trade openness in the long run moreover the findings confirm the existence of an environmental kuznets curve in the case of china

financial development and international trade is there a link the author explores a possible link between financial development and trade in manufactures his theoretical model focuses on the role of financial intermediaries in facilitating large scale high return projects results show that economies with better developed financial sectors have a comparative advantage in manufacturing industries he provides evidence for this hypothesis first proposed by kletzer and bardhan 1987 using a 30 year panel of data for 65 countries controlling for country specific effects and possible reverse causality he shows that financial development exerts a large causal impact on the level of both exports and the trade balance of manufactured goods

double marginalization and coordination in the supply chain with uncertain supply abstract this paper explores a generalized supply chain model subject to supply uncertainty after the supplier chooses the production input level decentralized systems under wholesale price contracts are investigated with double marginalization effects shown to lead to supply insufficiencies in the cases of both deterministic and random demands we then design coordination contracts for each case and find that an accept all type of contract is required to coordinate the supply chain with random demand which is a much more complicated situation than that with deterministic demand examples are provided to illustrate the application of our findings to specific industrial domains moreover our coordination mechanisms are shown to be applicable to the multi supplier situation which fills the research gap on assembly system coordination with random yield and random demand under a voluntary compliance regime

analysis of an inventory system under supply uncertainty in this paper we analyze a periodic review single item inventory model under supply uncertainty the objective is to minimize expected holding and backorder costs over a finite planning horizon under the supply constraints the uncertainty in supply is modeled using a three point probability mass function the supply is either completely available partially available or the supply is unavailable machine breakdowns shortages in the capacity of the supplier strikes etc are possible causes of uncertainty in supply we demonstrate various properties of the expected cost function and show the optimality of order up to type policies using a stochastic dynamic programming formulation under the assumption of a bernoulli type supply process in which the supply is either completely available or unavailable and when the demand is deterministic and dynamic we provide a newsboy like formula which explicitly characterizes the optimal order up to levels an algorithm is given that computes the optimal inventory levels over the planning horizon extensions and computational analysis are presented for the case where the partial supply availability has positive probability of occurrence

price delivery time guarantees and capacity selection this paper studies the impact of using delivery time guarantees as a competitive strategy in service industries where demands are sensitive to both price and delivery time we assume that delivery reliability is crucial and investment in capacity expansion is plausible in order to maintain a high probability of delivering the time guarantee a mathematical framework is proposed to understand the interrelations among pricing delivery time guarantee and capacity expansion decisions specifically an optimization model is developed to determine the joint optimal selection of these three important decision variables with an objective of maximizing the average net profit we characterize the optimal decisions and study their qualitative behaviors as various parameters change we further present a numerical example to illustrate how the results of our model can be used to provide useful managerial insights for selecting the best competing strategies for firms with different operating characteristics our model and results are also applicable to a make to order manufacturing environment

modeling quantity discounts under general price sensitive demand functions optimal policies and relationships this paper presents models for determining optimal all unit and incremental quantity discount policies and investigates the effect of quantity discounts on increasing demand and ensuring pareto efficient transactions under general price sensitive demand functions the paper develops optimal quantity discount policies investigates their interrelationships and their benefits to both the supplier and the buyer and gains managerial insights for the scenarios of maximizing the supplier s profit and the joint profit we develop simple and efficient solution approaches for determining the all unit and the incremental optimal decision policies for general price sensitive demand functions we have three main findings first with price sensitive demand there are two incentives in offering quantity discounts increasing demand and ensuring pareto efficient transactions in most cases increasing demand dominates in justifying the offering of quantity discounts second using a single lot size associated with all efficient transactions as with the constant demand case does not hold with the price sensitive demand case third the optimal all unit quantity discount policy is equivalent to the optimal incremental quantity discount policy in benefiting both the supplier and the buyer

energy consumption carbon emissions and economic growth nexus in bangladesh cointegration and dynamic causality analysis abstract the paper investigates the possible existence of dynamic causality between energy consumption electricity consumption carbon emissions and economic growth in bangladesh first we have tested cointegration relationships using the johansen bi variate cointegration model this is complemented with an analysis of an auto regressive distributed lag model to examine the results robustness then the granger short run the long run and strong causality are tested with a vector error correction modelling framework the results indicate that uni directional causality exists from energy consumption to economic growth both in the short and the long run while a bi directional long run causality exists between electricity consumption and economic growth but no causal relationship exists in short run the strong causality results indicate bi directional causality for both the cases a uni directional causality runs from energy consumption to co 2 emission for the short run but feedback causality exists in the long run co 2 granger causes economic growth both in the short and in the long run an important policy implication is that energy electricity as well can be considered as an important factor for the economic growth in bangladesh moreover as higher energy consumption also means higher pollution in the long run policy makers should stimulate alternative energy sources for meeting up the increasing energy demand

sub supply chain coordination in a three layer chain under demand uncertainty and random yield in production abstract one of the major objectives of modern supply chain management is to deal with the growing decentralization among the involved entities and hence minimizing the double marginalization effect inside the chain especially when the end customers demand is not deterministic to address this a three layer supply chain with one raw material supplier one manufacturer and one retailer is developed and studied in this paper effects of both supply chain coordination as well as sub supply chain coordination are examined optimal order and production quantities are obtained for the centralized system which depicts the scenario under coordination optimal order quantities and expected profits of the individual channel actors are maximized locally in the decentralized system under commonly used price only contract semi integrated models are also studied under price only contract the optimal strategies under different power structures are compared and the effects of the channel parameters on the optimal strategies are also examined numerical example is given to illustrate the developed model

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

monetary policy in a markov switching vector error correction model monetary policy vector autoregressions vars typically presume stability of the long run outcomes we introduce the possibility of switches in the long run equilibrium in a cointegrated var by allowing both the covariance matrix and weighting matrix in the error correction term to switch we find that monetary policy alternates between sustaining long run growth and disinflationary regimes allowing state changes can also help explain the price puzzle and justify the use of commodity prices as a corrective measure finally we show that regime switching has implications for disinflationary monetary policy and can explain the variety of sacrifice ratio estimates that exist in the literature

joint pricing and inventory policies for make to stock products with deterministic price sensitive demand abstract in this paper we focus on a firm selling a single make to stock product to price sensitive end customers we develop an integrated operations marketing model that can help determine the relevant profit maximizing decision variable values for two pricing policies that the firm might follow price as a decision variable which is advocated by academicians and mark up pricing used by most practitioners we first consider an eoq based model with price and order quantity as independent decision variables we then develop an analogous model where price is a mark up over operating costs per unit and order quantity becomes the sole decision variable we are able to ascertain the optimal decision variable values for each model for log linear and linear demand functions we prove that for such profit maximizing models the optimal batch size is not necessarily monotone increasing in set up cost interestingly our numerical analytical evidence suggests that from a profit perspective it is better for managers to be aggressive on price rather than reducing price too much especially for highly price sensitive and non linear demand moreover we establish that in general the profit penalty for not including inventory costs in determining the optimal batch size or ignoring the batch size optimization issue in a mark up price model is not significant only when the set up cost is quite high and or the firm faces non linear demand from highly price sensitive end consumers does it become crucial for managers to determine the exact optimal batch size and base the mark up price on the entire unit operating cost not only the unit variable production cost

the long run and causal analysis of energy growth openness and financial development on carbon emissions in turkey abstract the aim of this paper is to examine the causal relationship between financial development trade economic growth energy consumption and carbon emissions in turkey for the 1960 2007 period the bounds f test for cointegration test yields evidence of a long run relationship between per capita carbon emissions per capita energy consumption per capita real income the square of per capita real income openness and financial development the results show that an increase in foreign trade to gdp ratio results an increase in per capita carbon emissions and financial development variable has no significant effect on per capita carbon emissions in the long run these results also support the validity of ekc hypothesis in the turkish economy it means that the level of co 2 emissions initially increases with income until it reaches its stabilization point then it declines in turkey in addition the paper explores causal relationship between the variables by using error correction based granger causality models

coordinated decisions for substitutable products in a common retailer supply chain abstract this paper studies coordination mechanisms in a supply chain which consists of two suppliers with capacity uncertainties selling differential yet substitutable products through a common retailer who faces price sensitive random demand of these two products we develop in a noncompetitive setting three coordination models revenue sharing return policy and combination of revenue sharing and return policy and contrast them with a basic and uncoordinated model we are able to establish the ordinal relationship among the retailer s ordering and pricing decisions and analytically compare the performances between certain models when two suppliers are identical we find that the retailer s ordering and pricing decisions in the model with return policy in the case of identical suppliers are independent of demand or supply uncertainty our numerical results reveal that the performances of coordination models in the case of nonidentical suppliers resemble those in the case of identical suppliers we find that the retailer will place a larger order quantity in models where her average cost per unit sold is smaller we also find that product substitutability and uncertainties have different effects on chain performances

the effects of disease on optimal forest rotation a generalisable analytical framework the arrival of novel pathogens and pests can have a devastating effect on the market values of forests calibrating management strategies decisions to consider the effect of disease may help to reduce disease impacts on forests here we use a novel generalisable bioeconomic model framework which combines an epidemiological compartmental model with a faustmann optimal rotation length model to explore the management decision of when to harvest a single rotation even aged plantation forest under varying disease conditions sensitivity analysis of the rate of spread of infection and the effect of disease on the timber value reveals a key trade off between waiting for the timber to grow and the infection spreading further we show that the optimal rotation length which maximises the net present value of the forest is reduced when timber from infected trees has no value but when the infection spreads quickly and the value of timber from infected trees is non zero it can be optimal to wait until the disease free optimal rotation length to harvest our original approach provides an exemplar framework showing how a bioeconomic model can be used to examine the effect of tree diseases on management strategies decisions

decomposition of us manufacturing energy intensity and elasticities of components with respect to energy prices this paper proposes an analysis of changes in the us manufacturing energy intensity between 1974 and 1998 the starting point is a three term decomposition of an intensity index which evaluates annually the respective contributions of changes in industrial structure efficiency gains at the sectoral level and substitution between energy resources to aggregate productivity improvements then we study the time paths followed by each of these three components using spectral analysis techniques we show that they behave very differently as the structural influence plays a part mainly in the short run substitution between energy resources acts principally in the long run and the changes in sectoral intensity cause both trend variations and cyclical ones finally we focus on the effect of energy price evolution on each of the three components allowing energy price rises and decreases to have asymmetric effects we estimate both the long run impacts and the short run adjustments

energy and output dynamics in bangladesh the relationship between energy consumption and output is still ambiguous in the existing literature the economy of bangladesh having spectacular output growth and rising energy demand as well as energy efficiency in recent decades can be an ideal case for examining energy output dynamics we find that while fluctuations in energy consumption do not affect output fluctuations movements in output inversely affect movements in energy use the results of granger causality tests in this respect are consistent with those of innovative accounting that includes variance decompositions and impulse responses autoregressive distributed lag models also suggest a role of output in bangladesh s energy use hence the findings of this study have policy implications for other developing nations where measures for energy conservation and efficiency can be relevant in policymaking

channel coordination and quantity discounts this paper presents a model for analyzing the impact of joint decision policies on channel coordination in a system consisting of a supplier and a group of homogeneous buyers the joint decision policy characterized by the unit selling price and the order quantity is coordinated through quantity discounts and franchise fees both the annual demand rate and the operating cost including the purchase ordering and inventory holding costs depend on the joint decision policy employed this paper contributes by integrating work addressing quantity discounts on inventory and ordering policies and work focusing on the control mechanism provided by quantity discounts in channel coordination it is shown that the optimal all unit quantity discount policy is equivalent to the optimal incremental quantity discount policy in achieving channel coordination furthermore it is shown that quantity discounts alone are not sufficient to guarantee joint profit maximization the analyses of the general models are illustrated by specific analytical results obtained for a given demand function
