natural gas price elasticities variations by region and by sector in the usa abstract this article s primary objective is to estimate the own price and cross price elasticities of demand for natural gas in the residential commercial and industrial sectors by doe region in the usa a simultaneous equations model was developed and its reduced form was employed for natural gas consumption demand elasticity estimation in conjuction with the instrumental price variables data from 1967 to 1978 were used in the estimation but the 1973 oil embargo effect was separated with the use of a dummy variable the demand for natural gas was much more price elastic in the long run than in the short run and the industrial sector was more less price sensitive than others however there were significant interregional and intersectoral variations among the elasticities estimated

on the demand for natural gas in urban china abstract using a set of unbalanced panel data for chinese s cities during the period of 2006 2009 this study aims to estimate the price and income elasticities of residential demand for natural gas natural gas consumption is specified as a function of its own price substitute prices urban wages and other supply climate and housing characteristics using a feasible generalised least squares fgls technique which controls for panel heteroskedasticity and panel correlation we find that natural gas consumption is price elastic and income inelastic when other covariates e g the supply of natural gas pipeline and heating degree days are controlled in addition there are large variations in demand behaviours across china s regions there is a substantial income effect on demand for natural gas in southern china whereas the northern regions are found to have a higher price effect in addition the substitution effect between coal and natural gas is significant in north china but is not significant in south china these findings have several important policy implications for natural gas pricing and supply cost analysis in the context of china

residential consumption of gas and electricity in the u s the role of prices and income abstract we study the residential demand for electricity and gas working with nationwide household level data that cover recent years namely 1997 2007 our dataset is a mixed panel multi year cross sections of dwellings households in the 50 largest metropolitan areas in the united states as of 2008 we estimate static and dynamic models of electricity and gas demand we find strong household response to energy prices both in the short and long term from the static models we get estimates of the own price elasticity of electricity demand in the 0 860 to 0 667 range while the own price elasticity of gas demand is 0 693 to 0 566 these results are robust to a variety of checks contrary to earlier literature metcalf and hassett 1999 reiss and white 2005 we find no evidence of significantly different elasticities across households with electric and gas heat the price elasticity of electricity demand declines with income but the magnitude of this effect is small these results are in sharp contrast to much of the literature on residential energy consumption in the united states and with the figures used in current government agency practice our results suggest that there might be greater potential for policies which affect energy price than may have been previously appreciated

capital markets and firm organization how financial development shapes european corporate groups we investigate the effect of financial development on the formation of european corporate groups because cross country regressions are hard to interpret in a causal sense we exploit exogenous industry measures to investigate a specific channel through which financial development may affect group affiliation internal capital markets using a comprehensive firm level data set on european corporate groups in 15 countries we find that countries with less developed financial markets have a higher percentage of group affiliates in more capital intensive industries this relationship is more pronounced for young and small firms and for affiliates of large and diversified groups our findings are consistent with the view that internal capital markets may under some conditions be more efficient than prevailing external markets and that this may drive group affiliation even in developed economies this paper was accepted by bruno cassiman business strategy

the demand for coal among china s rural households estimates of price and income elasticities abstract china s residential sector has experienced rapid electrification and gasification among rural households however coal still accounts for a large share of energy use especially in the north use of coal for cooking and heating brings large health and pollution risks from a theoretical viewpoint economic tools such as taxes and subsidies have the potential to play a crucial role in addressing this issue in this paper a provincial level dataset is used to estimate the price and income elasticities of aggregate coal demand by rural households we find that coal is a non giffen inferior good for the rural household sector this means that future income growth may help to induce switching from coal demand is becoming more price elastic as rural incomes grow we also find that rural residential coal demand is more price and income responsive in the south than the north perhaps because of fewer substitution options in the north our results provide benchmarks and parameters for policy simulation research

estimation of short run and long run elasticities of energy demand from panel data using shrinkage estimators this article discusses the problem of obtaining short run and long run elasticities of energy demand for each of 49 states in the united states using data for 21 years estimation using the time series data by each state gave several wrong signs for the coefficients estimation using pooled data was not valid because the hypothesis of homogeneity of the coefficients was rejected shrinkage estimators gave more reasonable results the article presents in a unified framework the classical empirical bayes and bayes approaches for deriving these estimators

how do urban households in china respond to increasing block pricing in electricity evidence from a fuzzy regression discontinuity approach abstract china is the largest electricity consumption country after it has passed the united states in 2011 residential electricity consumption in china grew by 381 35 12 85 per annum between 2000 and 2013 in order to deal with rapid growth in residential electricity consumption an increasing block pricing policy was introduced for residential electricity consumers in china on july 1st 2012 using difference in differences models with a fuzzy regression discontinuity design we estimate a causal effect of price on electricity consumption for urban households during the introduction of increasing block pricing policy in guangdong province of china we find that consumers do not respond to a smaller approximately 8 increase in marginal price however consumers do respond to a larger increase in marginal price an approximately 40 increase in marginal price induces an approximately 35 decrease in electricity use 284 kw h per month our results suggest that although the increasing block pricing could affect the behavior of households with higher electricity use there is only a limit potential to overall energy conservation

the assessment japan s stagnation can policy revive the economy for a decade now japan has virtually stagnated some blame this on a succession of unfavourable shocks that began with the bursting of the bubble economy more appropriate macroeconomic policies targeting inflation and or the exchange rate could in this view lead to a revival others argue that the country s problems are deeper seated and require major structural reforms many aspects of japan s distinctive economic system should in this view be either jettisoned or profoundly changed it is unlikely that demand management policies can add much to what they have done so far deregulation is needed in many areas and would no doubt help but a wholesale rejection of erstwhile institutions and practices does not seem on the cards and might well be disruptive copyright 2000 by oxford university press

are family firms good employers family firms employ about 60 percent of the global workforce while it is widely assumed that they are good employers data about their conduct is mixed in this study we extend stewardship and agency theories to test competing propositions about the impact of family on employment practices using data from 14 961 private belgian firms over a 19 year period higher investments lower dividend payout and higher risk tolerance indicate that family firms are better financial stewards of their companies than nonfamily firms however family firms are worse organizational stewards than nonfamily firms they offer lower compensation invest less in employee training and exhibit higher voluntary turnover and lower labor productivity further and contrary to earlier research we find that financial practices in private family firms do not change over time and that the deleterious influence of family on employment practices rises with both firm age and with heightened family involvement together our findings suggest that a more nuanced understanding of stewardship and agency theory is needed to understand the impact of family on the governance of private firms

come aboard exploring the effects of directorships in the executive labor market in this study we examine the following question what do executives gain from serving on boards we propose that board service benefits non ceo level executives in the executive labor market by acting as a certification mechanism and by providing access to unique knowledge skills and connections we argue that non ceo executives who gain directorships will be more likely to be promoted to ceo both inside and outside their home firm will be more likely to be promoted internally and will receive higher pay from their home firms to test our ideas we employ propensity score matching to construct a longitudinal sample of 2 104 top executives of large publicly traded companies in the united states over the period 1996 to 2012 the results provide consistent support for our theory

the ex post impact of an energy tax on household energy demand this paper presents an econometric study dealing with household demand for energy in the netherlands the main objective of the paper is to present an estimation of the actual impact of an already implemented energy tax introduced in the netherlands in 1996 the approach differs from the existing literature in that 1 it uses panel data for the same period in which the tax was introduced and 2 it estimates a demand function that controls for a large set of variables such as outside temperature type of house and of house insulation household cooking behavior and an extensive number of durable goods and electrical appliances the study concludes that in the short term the energy tax had a small but significant impact on energy consumption in the netherlands concretely the yearly average demand reduction was of 8 for electricity and 4 4 for gas additionally the influence of variables other than price and income on household energy demand is discussed using this information the impact that the energy tax had on household energy use can be compared with the energy reduction that could have been achieved when using other policy instruments

review of key international demand elasticities for major industrializing economies abstract this paper conducts a selective review of various estimates for energy demand responses focused specially upon lower income industrializing economies rather than richer mature nations it emphasizes recent trends from empirical studies that have been published after 2000 emphasis is placed on the five major emerging or transitional economies in brazil china india mexico and russia although other important nations like chile and south korea are also discussed when studies are available the review focuses attention on the long run responses to changes in prices and income after capital stock turnover has been completed the terminology often refers to elasticities or the percentage change in energy use divided by the percentage change in price or income holding constant all other factors that could influence energy use decisions estimates cover petroleum products natural gas and electricity although the available studies often ignore coal they also include the economy wide impacts real gdp to price changes most studies have focused upon household and transportation use of liquid fuels many fewer studies have investigated fuels used by industry or commerce or for electric generation based upon the available estimates price and income elasticities for liquid fuels are generally less than one unity for many countries and sectors except for the long run income effect for transportation purposes which can range widely by country between 0 24 and 1 75 while averaging 0 94 for all countries

dominant institutional owners and firm value abstract this research analyzes the impact of control by dominant institutional owners banking institutions and investment funds on firm value the analysis considers the level of voting rights in the hands of the dominant institutional owner and other large shareholders the results reveal a different effect on value depending on whether the dominant institutional investor is a banking institution or an investment fund moreover the results show that the presence of other large shareholders affects firm value when a dominant institutional owner controls the firm

you paid for the skills now keep them tuition reimbursement and voluntary turnover does investing in employees marketable skills reduce turnover this study uses insights from human capital theory to explain how general skill development and promotion relate to voluntary turnover data from 9 439 salaried employees of a large manufacturer show that participation in tuition reimbursement reduces turnover while employees are in school voluntary turnover increases when individuals earn graduate degrees but is significantly reduced if they are subsequently promoted

the ecological fallacy revisited aggregate versus individual level findings on economics and elections and sociotropic voting several aggregate level studies have found a relationship between macroeconomic conditions and election outcomes operating in intuitively plausible directions more recent survey based studies however have been unable to detect any comparable relationship operating at the individual voter level this persistent discrepancy is puzzling one recently proposed explanation for it is that voters actually behave in an altruistic or sociotropic fashion responding to economic events only as they affect the general welfare rather than in terms of self interested pocketbook considerations it is argued here that the discrepancies between the macro and micro level studies are a statistical artifact arising from the fact that observable changes in individual welfare actually consist of two unobservable components a government induced and politically relevant component and an exogenous component caused by life cycle and other politically irrelevant factors it is shown that because of this individual level cross sectional estimates of the effects of welfare changes on voting are badly biased and are essentially unrelated to the true values of the behavioral parameters of interest they will generally be considerable underestimates and may even be of the wrong sign an aggregate level time series analysis on the other hand will often yield reasonably good if somewhat attenuated estimates of the underlying individual level effects of interest thus in this case individual behavior is best investigated with aggregate rather than individual level data it is also shown that the evidence for sociotropic voting is artifactual in the sense that the various findings and evidence which ostensibly show sociotropic behavior are all perfectly compatible with the null hypothesis of self interested pocketbook voting

growth diversification and business group formation in entrepreneurial firms recent empirical research has demonstrated that the growth process of entrepreneurial firms is frequently achieved through the formation of business groups i e a set of companies run by the same entrepreneur or entrepreneurial team this has been hypothesised as result of a growth process by diversification of the original activity this entrepreneurial growth process offers an alternative explanation for the formation of business groups than that arising from managerial efficiency and expediency the main aim of the article is to explore group formation through entrepreneurial diversification using a sample of high growth entrepreneurial firms the analysis demonstrates that the running of a group of companies by the same entrepreneur is not only induced by the geographical extension of their operation and by diversification but also by the differentiation policy aimed at serving different market segments within the same sector this seems to contrast with the diversification policy and organisational setting of large managerial firms

who should control a corporation toward a contingency stakeholder model for allocating ownership rights a number of companies allocate ownership rights to stakeholders different from shareholders despite the fact that the law attributes these rights to the equity holders this article contributes to an understanding of this evidence by developing a contingency model for the allocation of ownership rights the model sheds light on why companies despite pressures from the law vary in their allocation of ownership rights the model is based on the assumption that corporations increase their chance to survive and prosper if the stakeholders supplying critical contributions receive the ownership rights according to the model critical contributions involve 1 contractual problems due to specific investments long term relationships and low measurability 2 the assumption of the uncertainty resting on the company and 3 the supply of scarce and valuable resources the model is dynamic because it also provides a basis for understanding why the allocation of ownership rights changes with time finally the article presents the strategies companies can use to realize an efficient distribution of ownership rights among their stakeholders

output consumption and the stock market implications for european convergence this paper investigates the nature of the relationship between output and stock prices and consumption and stock prices with respect to the different financial structures that exist primarily in the european union eu evidence is found of a long run relationship for both relationships with the exception of germany and to an extent france which is argued is due to their bank dominated financial systems kalman filter estimates reveal that both relationships have increased in strength although little evidence is found of any convergence in the strength of the relationship across the eu

the demand for electricity and natural gas in the northeastern united states the demand for natural gas and electricity for the residential commercial and industrial sectors was estimated using a combination of the error components model and seemingly unrelated regressions the estimated demand models showed both natural gas and electricity to be price elastic in the long run and price inelastic in the short run in all sectors except the commercial sector in which electricity demand is unresponsive to its own price natural gas had negligible income elasticities in the residential and commercial sectors and a long run income elasticity of 2 86 in the industrial sector electricity had an insignificant income effect in all sectors but the industrial where its long run elasticity was unitary only in the residential demand for natural gas is the cross price elasticity substantial with the price of electricity having a long run cross elasticity of 1 70 fuel oil prices generally had a negative impact probably indicating a large income effect the elasticities of adjustment were higher for natural gas than electricity indicating a faster adjustment to change either in response to greater instability in energy availability or reflecting more alternative fuels or both 16 references 4 tables
