energy consumption and economic growth nexus in tanzania an ardl bounds testing approach abstract in this paper we examine the intertemporal causal relationship between energy consumption and economic growth in tanzania during the period of 1971 2006 unlike the majority of the previous studies we employ the newly developed autoregressive distributed lag ardl bounds testing approach by pesaran et al 2001 bounds testing approaches to the analysis of level relationships journal of applied econometrics 16 289 326 to examine this linkage we also use two proxies of energy consumption namely total energy consumption per capita and electricity consumption per capita the results of the bounds test show that there is a stable long run relationship between each of the proxies of energy consumption and economic growth the results of the causality test on the other hand show that there is a unidirectional causal flow from total energy consumption to economic growth and a prima facie causal flow from electricity consumption to economic growth overall the study finds that energy consumption spurs economic growth in tanzania

financial sector reform and sustainable development the case of costa rica abstract how can financial sector reform be designed specifically so that it enhances the prospects for sustainable development this paper begins an analysis of this little discussed intersection with a focus on the problems and possibilities facing costa rica policy changes that encourage financial markets to incorporate long term environmental sustainability concerns will require moving beyond a standard model of financial liberalization flighty financial flows systemic pressures against innovation and unpriced environmental externalities all mean that real sector environmental performance will be adversely affected by financial sector dynamics lacking appropriate policy markers financial market policies must encourage market forces to channel capital flows that build productive capabilities based on complementarities between development and environmental quality costa rica s reform process and unusual depth of experience in pursuing sustainable development make it an ideal place for such financial market innovations to be attempted getting its incentive system right in financial restructuring could aid immensely in the emergence and application of sustainability based competitive capabilities a set of market based green financial reforms is proposed including tax advantaged banking and bond programs rural group lending and a single certification entity for potential borrowers in these programs

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

fines leniency and rewards in antitrust this article reports results from an experiment studying how fines leniency and rewards for whistleblowers affect cartel formation and prices antitrust without leniency reduces cartel formation but increases cartel prices subjects use costly fines as punishments leniency improves antitrust by strengthening deterrence but stabilizes surviving cartels subjects appear to anticipate the lower postconviction prices after reports leniency with rewards prices fall at the competitive level overall our results suggest a strong cartel deterrence potential for well run leniency and reward schemes these findings may also be relevant for similar white collar organized crimes such as corruption and fraud

energy consumption prices and economic growth in three ssa countries a comparative study in this paper we examine the causal relationship between energy consumption and economic growth in three sub saharan african countries namely south africa kenya and congo drc we incorporate prices as an intermittent variable in a bivariate setting between energy consumption and economic growth thereby creating a simple trivariate framework using the ardl bounds testing procedure we find that the causality between energy consumption and economic growth varies significantly across the countries under study the results show that for south africa and kenya there is a unidirectional causal flow from energy consumption to economic growth however for congo drc it is economic growth that drives energy consumption these findings have important policy implications insofar as energy conservation policies are concerned in the case of congo drc for example the implementation of energy conservation policies may not significantly affect economic growth because the country s economy is not entirely energy dependent however for south africa and kenya there is a need for more energy supply augmentations in order to cope with the long run energy demand in the short run however the two countries should explore more efficient and cost effective sources of energy in order to address the energy dependency problem

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

do meetings in smoke filled rooms facilitate collusion the sherman act prohibits firms from discussing prices in meetings traditional thought suggests that this prohibition makes it harder for firms to collude and economists have concluded that the sherman act operates in the public interest i provide an alternative explanation for the act that also accounts for the small sanctions chosen by the legislature when firms interact in a dynamic environment in which the law helps them to prevent renegotiation the firms may benefit from the law that makes it costly but not very costly to meet to discuss prices the sherman act may help firms to collude

the spillover effect of antitrust enforcement we address the question of how the threat of antitrust enforcement spills over from one industrial submarket to another we build a formal model describing the technology through which an initial antitrust indictment can reveal evidence of additional infractions in the same industry our approach is organized around the belief that the flow of information on antitrust violations is closely linked to commodity flows as it turns out our method proves able to explain the differential response of highway construction cartels in various states to recent changes in the severity of antitrust sanctions

electricity consumption and economic growth a time series experience for 17 african countries abstract while the availability of electricity by itself is not a panacea for the economic and social problems facing africa the supply of electricity is nevertheless believed to be a necessary requirement for africa s economic and social development this paper tests the long run and causal relationship between electricity consumption per capita and real gross domestic product gdp per capita for 17 african countries for the period 1971 2001 using a newly developed cointegration test proposed by pesaran et al 2001 and using a modified version of the granger causality test due to toda and yamamoto 1995 the advantage of using these two approaches is that they both avoid the pre testing bias associated with conventional unit root and cointegration tests the empirical evidence shows that there was a long run relationship between electricity consumption per capita and real gdp per capita for only 9 countries and granger causality for only 12 countries for 6 countries there was a positive uni directional causality running from real gdp per capita to electricity consumption per capita an opposite causality for 3 countries and bi directional causality for the remaining 3 countries the result should however be interpreted with care as electricity consumption accounts for less than 4 of total energy consumption in africa and only grid supplied electricity is taken into account

what determines cartel success following george stigler 1964 many economists assume that incentive problems undermine attempts by firms to collude to raise prices and restrict output but the potential profits from collusion can create a powerful incentive as well theory cannot tell us a priori which effect will dominate whether or when cartels succeed is thus an empirical question we examine a wide variety of empirical studies of cartels to answer the following questions 1 can cartels succeed 2 if so for how long 3 what impact do cartels have 4 what causes cartels to break up we conclude that many cartels do survive and that the distribution of duration is bimodal while the average duration of cartels across a range of studies is about five years many cartels break up very quickly i e in less than a year but there are many others that last between five and ten years and some that last decades limited evidence suggests that cartels are able to increase prices and profits to varying degrees cartels can also affect other non price variables including advertising innovation investment barriers to entry and concentration cartels break up occasionally because of cheating or lack of effective monitoring but the biggest challenges cartels face are entry and adjustment of the collusive agreement in response to changing economic conditions cartels that develop organizational structures that allow them the flexibility to respond to these changing conditions are more likely to survive price wars that erupt are often the result of bargaining issues that arise in such circumstances sophisticated cartel organizations are also able to develop multipronged strategies to monitor one another to deter cheating and a variety of interventions to increase barriers to entry

antitrust and prices this study examines the effects of antitrust prosecution on prices charged by firms indicted for price fixing in a survey of 25 cases filed between 1973 and 1984 prices are found to gradually rise by about 7 percent over the 4 years following an indictment however the severity of penalties is negatively correlated with prices these two findings suggest either that penalties are too lenient or that prosecution is too broad penalizing economically efficient conspiracies along with those that are inefficient

empirical evidence on a special interest group perspective to antitrust while the antitrust laws claim to serve the public interest they are as susceptible to the influence of special interest groups as are any public policies this paper extends the empirical literature regarding the special interest theory of antitrust our additional empirical evidence addresses some of the shortcomings in previous approaches in particular we conduct a more rigorous statistical examination this paper separates two crucial issues first what happened to prices and output from 1880 to 1900 prior to and following passage of the sherman act in 1890 second what do these empirical results mean for the origin history and development of antitrust

the causal relationship between electricity consumption and economic growth in the asean countries abstract this paper investigates the causal relationship between electricity consumption and economic growth among the association of south east asian nations asean 4 members namely indonesia malaysia singapore and thailand using modern time series techniques for the period 1971 2002 the results indicate that there is a bi directional causality between electricity consumption and economic growth in malaysia and singapore this means that an increase in electricity consumption directly affects economic growth and that economic growth also stimulates further electricity consumption in the two countries however uni directional causality runs from economic growth to electricity consumption in indonesia and thailand without any feedback effect thus electricity conservation policies can be initiated without deteriorating economic side effects in the two countries

causality between energy consumption and economic growth in india a note on conflicting results abstract this note examines the different direction of causal relation between energy consumption and economic growth in india applying engle granger cointegration approach combined with the standard granger causality test on indian data for the period 1950 1996 we find that bi directional causality exists between energy consumption and economic growth further we apply johansen multivariate cointegration technique on the different set of variables the same direction of causality exists between energy consumption and economic growth this is different from the results obtained in earlier studies

why nasdaq market makers avoid odd eighth quotes recent studies argue that implicit collusion explains the tendency of nasdaq market makers to avoid odd eighth price quotes this paper focuses on the role that preference trading plays in determining quoted spreads under the postulated effects of preference trading an analysis of the relation between spreads and price fractions explains the paucity of odd eighth quotes on nasdaq empirical results from a comprehensive data set show that exogenous economic characteristics explain the distribution of price fractions across securities and illustrate the stability of that distribution over time these results contradict empirical results offered as support for the collusion hypothesis

interpreting the dynamic nexus between energy consumption and economic growth empirical evidence from russia research on the nexus between energy consumption and economic growth is a fundamental topic for energy policy making and low carbon economic development russia proves the third largest energy consumption country in the world in recent years while little research has shed light upon its energy consumption issue till now especially its energy growth nexus therefore this paper empirically investigates the dynamic nexus of the two variables in russia based on the state space model the results indicate that first of all russia s energy consumption is cointegrated with its economic growth in a time varying way though they do not have static or average cointegration relationship hence it is unsuitable to merely portrait the nexus in an average manner second ever since the year of 2000 russia s energy efficiency has achieved much more promotion compared with that in previous decades mainly due to the industrial structure adjustment and technology progress third among bric countries the consistency of russia s energy consumption and economic growth appears the worst which suggests the complexity of energy growth nexus in russia finally there exists bi directional causality between russia s energy consumption and economic growth though their quantitative proportional relation does not have solid foundation according to the cointegration theory

the impact of collusion on price behavior empirical results from two recent cases abstract we use extended arch and garch models to examine the differences in the behavior of the first two moments of the price distribution during collusive and competitive phases of two recently discovered conspiracies citric acid and lysine according to our results the conspirators managed to raise prices by 9 and 25 cents per pound in the short run relative to non collusive periods also the variance of prices during the lysine conspiracy was lower and the variance of prices during the citric acid conspiracy was higher than during more competitive periods the proposed methodology may be used for antitrust screening and prosecution purposes

electricity consumption growth nexus the case of malaysia abstract the goal of this paper is to model the relationship between electricity consumption and real gross domestic product gdp for malaysia in a bivariate and multivariate framework we use time series data for the period 1971 2003 and apply the bounds testing approach to search for a long run relationship our results reveal that electricity consumption real gdp and price share a long run relationship the results of the autoregressive distributed lag ardl estimates of long run elasticity of electricity consumption on gdp are found to be around 0 7 and statistically significant finally in the short run the results of the causality test show that there is a unidirectional causal flow from electricity consumption to economic growth in malaysia from these findings we conclude that malaysia is an energy dependent country leading us to draw some policy implications this paper adds support and validity thus reducing the policy makers concern on the ambiguity of the electricity and growth nexus in malaysia

energy consumption pollutant emissions and economic growth in south africa article i nfo article history this paper examines the long run and the causal relationship between economic growth pollutant emissions and energy consumption for south africa for the period 1965 2006 in a multivariate framework which includes labour and capital as additional variables using the bound test approach to cointegration we found a short run as well as a long run relationship among the variables with a positive and a statistically significant relationship between pollutant emissions and economic growth further applying a modified version of the granger causality test we also found a unidirectional causality running from pollutant emissions to economic growth from energy consumption to economic growth and from energy consumption to co2 emissions all without a feedback the econometric evidence suggests that south africa has to sacrifice economic growth or reduce its energy consumption per unit of output or both in order to reduce pollutant emissions in the long run however it is possible to meet the energy needs of the country and at the same time reduce co2 emissions by developing energy alternatives to coal the main source of co2 emissions however the econometric results upon which the policy suggestions are made should be interpreted with care as they may not be sufficiently robust enough to categorically warrant the choice of an unpalatable policy option by south africa

the electricity consumption and gdp nexus for the fiji islands fiji is a small open island economy dependent on energy for its growth and development hence the relationship between energy consumption and economic growth is crucial for fiji s development in this paper we investigate the nexus between electricity consumption and economic growth for fiji within a multivariate framework through including the labour force variable we use the bounds testing approach to cointegration and find that electricity consumption gdp and labour force are only cointegrated when gdp is the endogenous variable we use the granger causality f test and find that in the long run causality runs from electricity consumption and labour force to gdp implying that fiji is an energy dependent country and thus energy conservation policies will have an adverse effect on fiji s economic growth

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

cartel overcharges survey and meta analysis abstract the article presents a novel meta regression analysis of the size of cartel overcharges from a sample of more than 800 observations collected from a wide variety of published sources the analysis of a subsample of 395 cartel episodes finds that duration legal environment and organizational characteristics of cartels explain variation in overcharge rates to a greater extent than the type of publication or the method of calculation overcharges tend to be significantly higher for durable international cartels secular decline is observed as antitrust enforcement regimes have stiffened
