capital market development in china abstract this paper examines why and how capital markets have developed in a low income socialist country it shows that the development is the response of economic agents operating under a more market oriented economic environment with a highly regulated and inefficient banking system this development has presented new policy challenges and opportunities the paper argues that the developmental effects of the emergence of capital markets in china can be as important as its impact on improving allocative efficiency and resource mobilization

population growth and savings in ldcs a survey article both population growth and savings have traditionally taken a certain place of pride among models of growth and development the purpose of this paper is to examine the literature concerning the hypothesis that the savings rate itself is a function of the population growth rate and this effect exacerbates the negative effect of population on economic growth the evidence is examined from three perspectives i macroeconomic effects of variations in the age structure of the population ii choice theoretic models of family decision making particularly the joint determination of fertility decisions and savings decisions and iii market level interactions of variables which determine individual decisions the paper concludes that both population growth and savings rates are inextricably tied up in the process of economic development there are many ways in which the two variables may interact but no generalizations can be safely made across countries

modeling the co movements between crude oil and refined petroleum markets abstract in this paper we investigate two types of asymmetries i e the asymmetry in the lower and upper tail dependences and the asymmetry in the propagation of crisis bubble between crude oil market and refined petroleum markets based on copula models thirteen copula models with different types of dependence structures and time varying dependence parameters are considered we find that in general the malm copula fits our sample data best based on aic criterion we find that lower and upper tail dependences are both positive indicating that crude oil and refined product markets tend to move together using the asymmetric copulas we find asymmetry in tail dependence between crude oil and heating oil returns and that between crude oil and jet fuel returns interestingly upper tail dependence is significantly greater than the lower tail dependence for the pre crisis period while the result is reversed for the post crisis period finally although our data prefers the nonexchangeable malm copula the asymmetry in the propagation of crisis bubble between crude oil and refined product returns is very weak

political instability and savings in less developed countries evidence from sub saharan africa a four equation model is used to investigate the effects of political instability pi on the savings rate in sub saharan africa utilising a comprehensive measure of pi we find that political instability has a deleterious effect on the savings rate both directly and indirectly through a reduction in investment and economic growth the negative effects of pi on savings rate occurs contemporaneously as well as with a lag we also find that economic growth has a stabilising effect on the political system and that not accounting for these effects through a simultaneous equations model results in biased coefficient estimates these relationships are robust with respect to model specification the implication of our results is that economic factors alone cannot explain the development process in less developed countries

how to identify trust and reciprocity this paper uses a three games or triadic design to identify trusting and reciprocating behavior a large literature on single game trust and reciprocity experiments is based on the implicit assumption that subjects do not have altruistic or inequality averse other regarding preferences such experimental designs test compound hypotheses that include the hypothesis that other regarding preferences do not affect behavior in contrast experiments with the triadic design do discriminate between transfers resulting from trust or reciprocity and transfers resulting from other regarding preferences that are not conditional on the behavior of others decomposing trust from altruism and reciprocity from altruism or inequality aversion is critical to obtaining empirical information that can guide the process of constructing models that can increase the empirical validity of game theory

why do people rate theory and evidence on online ratings abstract the rapid growth of online retail in the last decade has led to widespread use of consumer generated ratings this paper theoretically and experimentally identifies influences that drive consumers to rate products and examines how those factors can create distortions in product ratings by manipulating payoffs and effectively deactivating either the buyer or seller side of an artificial laboratory market raters behavior is decomposed into buyer centric and seller centric components the cost of providing a rating also plays a major role in influencing rating behavior with high and low quality sellers being rated more often than those of moderate quality

inflation its variability and consumption in selected latin american countries abstract the aim of this paper is to estimate the impact of inflation on consumer expenditures in argentina brazil and chile attention is also given to the impact of uncertainty about inflation and to the role of liquid assets

the variable rate of growth effect in the life cycle saving model the rate of growth in real gnp g affects the aggregate saving rate positively in life cycle saving models this rate of growth effect is invariably estimated as the coefficient of g in the saving function we show that other determinants of the saving rate influence the rate of growth effect in other words the rate of growth effect is not constant specifically the real rate of return on financial assets and the population dependency ratio determine the timing of saving over the life cycle and hence alter the rate of growth effect the dependency ratio also has an effect on the saving rate which is independent of g because it together with the foreign saving rate determines the level of saving over the life cycle

should investors include commodities in their portfolios after all new evidence abstract this paper investigates whether an investor is made better off by including commodities in a portfolio that consists of traditional asset classes first we revisit the posed question within an in sample setting by employing mean variance and non mean variance spanning tests then we form optimal portfolios by taking into account the higher order moments of the portfolio returns distribution and evaluate their out of sample performance under the in sample setting we find that commodities are beneficial only to non mean variance investors however these benefits are not preserved out of sample our findings challenge the alleged diversification benefits of commodities and are robust across a number of performance evaluation measures utility functions and datasets the results hold even when transaction costs are considered and across various sub periods not surprisingly the only exception appears over the 2005 2008 unprecedented commodity boom period

foreign aid and economic growth an econometric study of bangladesh bangladesh is one of the poorest countries in the world since independence in 1971 bangladesh has received a large inflow of foreign capital from various countries for rapid economic progress bangladesh thus provides a test case for examining the effectiveness of foreign capital in promoting economic growth focussing on the supply side of the economy an econometric model is developed to quantify the effects of foreign aid and its various components on economic growth the model is tested using available time series data on bangladesh from 1972 to 1988 keeping data limitations measurement problems and other econometric problems in mind the empirical results indicate the domestic resources exert a stronger impact on growth than foreign resources foreign resources in its highly aggregative form do not show any significant contribution to growth however its decomposition into various components show that loans are more effective than grants and food aid is more effective than commodity or period

a note on the conditional correlation between energy prices evidence from future markets abstract we model the joint movements of daily returns on one month futures for crude oil heating oil and natural gas through the multivariate garch with dynamic conditional correlations and elliptical distributions introduced by pelagatti and rondena pelagatti m m rondena s 2007 dynamic conditional correlation with elliptical distributions unpublished manuscript universita di milano bicocca august futures prices of crude and heating oil covary strongly the conditional correlation between the futures prices of natural gas and crude oil has been rising over the last 5 years however this correlation has been low on average over two thirds of the sample suggesting that future markets have no established tradition of pricing natural gas as a function of developments on oil markets

the nature of the savings function in developing countries a survey of the theoretical and empirical literature the savings rate marginal or average is regarded as a key performance indicator by development economists and foreign aid practitioners admonish their clients to increase their savings ratio as a primary condition for achieving a satisfactory rate of economic growth however not only have questions been raised regarding the significance of the savings effort as an independent determinant of economic progress but the formulation of policies designed to increase the savings propensity has suffered from a dearth of knowledge regarding the nature of the savings function in developing countries a number of alternative savings hypotheses derived mainly from the literature relating to developed economies have been advanced but the paucity of reliable data has made it difficult to test these hypotheses and obtain results which warrant a reasonable degree of confidence the purpose of this article is a to review the theoretical and empirical literature on the savings function in developing countries b to assess critically the findings with respect to the major hypotheses and c to summarize the state of our knowledge on this important topic we shall begin with a brief review of the nature of the data on savings in developing countries with which economic analysts must work

determinants of private savings behaviour in turkey this study investigates the effects on private saving rates of a number of policy and non policy variables the analysis covers the period 1968 1994 the empirical private saving model for turkey is estimated the findings support the hypothesis that private saving rates have strong inertia the evidence indicates that government saving does not tend to crowd out private savings and the ricardian equivalence does not hold strictly income level has a positive impact on private saving rate and growth rate of income is not statistically significant from a policy point of view financial depth and development measures in turkey suggest that countries with deeper financial systems tend to have higher private saving rates private credit and real interest rates try to capture the severity of the borrowing constraints and the degree of financial repression for turkey moreover the negative impact of life expectancy rate lends support to the life cycle hypothesis the precautionary motive for saving is suppor

financial liberalization in africa abstract recent evidence has shown that african economies are financially repressed and the underlying motives for perpetuating repressive policies still exist increasing real deposit rates mainly through lower inflation promotes financial savings investment and growth financial liberalization in africa has recorded limited success owing to a high and unstable inflation rate the high cost of financial intermediation low bank demand for deposits and persistent government interference in credit markets chronically high fiscal deficits and their adverse impacts on the balance of payments also constitute hurdles for financial deepening in africa

dependency rates and savings rates reply arthur goldberger s comment is a tempest in a teacup this is readily verified from the data presented in table 1 this table reproduces from my original paper the coefficients for paired equations estimated with three different samples in which in s n and ln si y were the dependent variables as the data of table 1 indicate in 7 of the 12 cases the coefficients are identical through the second decimal place furthermore all the discrepancies are quantitatively very small in 9 cases the paired parameter estimates are within 1 percent of each other in the remaining cases the differences are of the magnitude of 0825 0012 and 0011 these are well within the margins of accuracy within which anyone views data generated from the national income accounts of the less developed countries in light of these considerations it is difficult to understand the tone of goldberger s comment the reason for the slight discrepancies is straightforward my observations for s n and s y were computed separately from data supplied by the statistical office of the agency for international development with the rounding introduced by the series for n and y it is not surprising that the series for s n is not identically equal to the series which would be obtained by forming s n from the product of y n and s y similar slight discrepancies have also been reported in other econometric work in which equations for s n and s y have been estimated with separately computed data series in any case nowhere in my paper did i even refer to the precise numerical parameter estimates obtained in my equations the main conclusions of the paper were that the dependency variables were quantitatively an important determinant of international savings rates and further that introduction of these variables greatly reduced the importance of percapita income on which some previous discussions had focused neither of these conclusions is affected by goldberger s comment

dynamics of oil price precious metal prices and exchange rate this study examines the co movements and information transmission among the spot prices of four precious metals gold silver platinum and palladium oil price and the us dollar euro exchange rate we find evidence of a weak long run equilibrium relationship but strong feedbacks in the short run the spot precious metal markets respond significantly but temporarily to a shock in any of the prices of the other metal prices and the exchange rate furthermore we discover some evidence of market overreactions in the palladium and platinum cases as well as in the exchange rate market in conclusion whether there are overreactions and re adjustments or not investors may diversify at least a portion of the risk away by investing in precious metals oil and the euro policy implications are provided

dependence and extreme dependence of crude oil and natural gas prices with applications to risk management abstract in this article we show how the copula garch approach can be appropriately used to investigate the conditional dependence structure between the crude oil and natural gas markets as well as to derive implications for portfolio risk management in extreme economic conditions using daily price data from january 1997 to october 2011 our in sample results show evidence of asymmetric dependence between the two markets the crude oil and gas markets tend to comove closely together during bullish periods but not at all during bearish periods moreover taking the extreme comovement into account leads to an improvement in the accuracy of the out of sample value at risk forecasts

disequilibrium analysis in developing economies an overview a general theory of distortions in product and in factor markets distinguishes between endogenous and policy imposed distortions the literature has tended to focus on policy imposed distortions in product markets and on endogenous distortions in factor markets this paper analyzes policy imposed distortions in product and in factor markets of developing economies section i briefly describes the principal policy imposed distortions observed reviews recent estimates on the extent of discrimination in particular markets and indicates their possible economic effects section ii reports on available estimates of the impact of these distortions on the efficiency of allocating existing resources as well as on savings investment efficiency and economic growth

separating reputation social influence and identification effects in a dictator game abstract this study explores the ways in which information about other individual s action affects one s own behavior in a dictator game the experimental design discriminates behaviorally between three possible effects of recipient s within game reputation on the dictator s decision reputation causing indirect reciprocity social influence and identification the separation of motives is an important step in trying to understand how impulses towards selfish or generous behavior arise the statistical analysis of experimental data reveals that the reputation effects have a stronger impact on dictators actions than the social influence and identification

the short and long run efficiency of energy precious metals and base metals markets evidence from the exponential smooth transition autoregressive models abstract the aim of this paper is to investigate the long and short run relationship between spot and futures prices of the energy precious metals and base metals markets we analyze daily data from january 1985 to february 2019 the empirical findings based on the cointegration test which follows a nonlinear process suggest that the spot prices of energy and metals assets have long run relationships with their futures prices nonparametric granger causality test results also indicate bi directional causality among futures and spot prices these findings indicate that the energy and metals markets are informationally efficient in the sense of fama 1970

impacts of official development assistance on agricultural growth savings and agricultural imports abstract this paper explores the links between development assistance agricultural output growth and imports in 56 developing economies over the period 1974 1990 the empirical model treats agricultural growth and imports savings and aid as endogenous the analysis also accounts for differences in macroeconomic policies the results show that aid had a positive impact on agricultural growth a robust relationship exits between aid and agricultural imports consistent with the argument that aid helps industrialized countries through market expansion and strengthened trade ties

interest rates savings and growth in ldcs an assessment of recent empirical research abstract the mckinnon shaw proposition of a positive interest responsiveness of savings and the beneficial effects of financial liberalization policies on economic growth has been an issue of considerable debate and a foundation of policy practice in less developed countries ldcs this paper aims at assessing critically a number of recent contributions to the empirical literature dealing with this proposition the need to advance more knowledge in this field on empirical grounds is argued despite the data conceptual and methodological shortcomings faced in making these efforts the main conclusion of this paper is that the debate is far from being settled even for those countries on which empirical research has focused

assessing the impact of interest rates in less developed countries abstract empirical results obtained do not unambiguously support what one should expect on the basis of conventional economic theory cross country evidence on the average relationship for 64 ldcs during the period 1971 1980 between some of the macroeconomic variables such as rate of growth of real gdp real financial assets saving income and investment income ratios and rate of return on investment on the one hand and the level of the real interest rate on the other is analyzed by applying a non parametric mann whitney test it is found that there is no difference with any statistical significance between the two groups of ldcs above and below the mean real interest rate this implies that the level of the real interest rate by itself has little or no impact on the selected macroeconomic variables

on the short and long run efficiency of energy and precious metal markets this article contributes to the related literature by empirically investigating the efficiency of nine energy and precious metal markets over the last decades employing several pronounced models we test for both short and the long run efficiency using in addition to linear cointegration models nonlinear cointegration and error correction models ecms which allow the efficiency intensity to change per regime our findings can be summarized as follows i futures prices are found to be cointegrated with spot prices but they do not constitute unbiased predictors of future spot prices ii the hypothesis of risk neutrality is rejected iii the short run efficiency hypothesis is rejected suggesting that using past futures price returns improves the modeling and forecasting of future spot prices and iv the nonlinear modeling suggests the presence of two distinct regimes wherein the first regime the efficiency hypothesis is supported whereas in the second it is rejected the empirical findings have important implications for producers hedgers speculators and policymakers

household saving in developing countries first cross country evidence although most studies have relied on domestic or private sector saving data this article uses household data available from the u n system of national accounts for a sample of 10 countries household saving functions are estimated using combined time series and cross country observations in order to test households responses to income and growth rates of return monetary wealth foreign saving and demographic variables the results show that income and wealth variables affect saving strongly and in ways consistent with standard theories inflation and the interest rate do not show clear effects on saving which is also consistent with their theoretical ambiguity foreign saving and monetary assets have strong negative effects on household saving which suggests the importance of liquidity constraints and monetary wealth in developing countries

the propensities to consume labour and property incomes in the commonwealth caribbean this article outlines theoretically the aggregate savings implications of differences in business and personal savings propensities time series empirical tests for two developing economies generate the conclusion that the marginal business savings rate is much higher than the marginal personal savings rate for double log consumption functions differences in the personal propensity to consume labour and property incomes are substantial and statistically significant

savings and nutrition at low incomes while many development theorists assume saving propensities vary among different groups there has been limited theoretical justification for this view this paper analyzes two complementary theories stressing the effect on saving of physiological consequences of poor nutrition at low incomes one influence is on the probability of survival another is on workers productivity either effect means that the average propensity to save can rise with income issues considered include annuities exogenous changes in survival and efficiency implications for the efficiency wage theory of unemployment and distinctions between wage and nonwage income implications of nutritional effects for econometric specification of saving functions are stressed

a new statistic and practical guidelines for nonparametric granger causality testing abstract in this paper we introduce a new nonparametric test for granger non causality which avoids the over rejection observed in the frequently used test proposed by hiemstra and jones 1994 testing for linear and nonlinear granger causality in the stock price volume relation journal of finance 49 1639 1664 after illustrating the problem by showing that rejection probabilities under the null hypothesis may tend to one as the sample size increases we study the reason behind this phenomenon analytically it turns out that the hiemstra jones test for the null of granger non causality which can be rephrased in terms of conditional independence of two vectors x and z given a third vector y is sensitive to variations in the conditional distributions of x and z that may be present under the null to overcome this problem we replace the global test statistic by an average of local conditional dependence measures by letting the bandwidth tend to zero at appropriate rates the variations in the conditional distributions are accounted for automatically based on asymptotic theory we formulate practical guidelines for choosing the bandwidth depending on the sample size we conclude with an application to historical returns and trading volumes of the standard and poor s index which indicates that the evidence for volume granger causing returns is weaker than suggested by the hiemstra jones test

testing for linear and nonlinear granger causality in the stock price volume relation linear and nonlinear granger causality tests are used to examine the dynamic relation between daily dow jones stock returns and percentage changes in new york stock exchange trading volume we find evidence of significant bidirectional nonlinear causality between returns and volume we also examine whether the nonlinear causality from volume to returns can be explained by volume serving as a proxy for information flow in the stochastic process generating stock return variance as suggested by clark s 1973 latent common factor model after controlling for volatility persistence in returns we continue to find evidence of nonlinear causality from volume to returns

world oil and agricultural commodity prices evidence from nonlinear causality abstract the increasing co movements between the world oil and agricultural commodity prices have renewed interest in determining price transmission from oil prices to those of agricultural commodities this study extends the literature on the oil agricultural commodity prices nexus which particularly concentrates on nonlinear causal relationships between the world oil and three key agricultural commodity prices corn soybeans and wheat to this end the linear causality approach of toda yamamoto and the nonparametric causality method of diks panchenko are applied to the weekly data spanning from 1994 to 2010 the linear causality analysis indicates that the oil prices and the agricultural commodity prices do not influence each other which supports evidence on the neutrality hypothesis in contrast the nonlinear causality analysis shows that i there are nonlinear feedbacks between the oil and the agricultural prices and ii there is a persistent unidirectional nonlinear causality running from the oil prices to the corn and to the soybeans prices the findings from the nonlinear causality analysis therefore provide clues for better understanding the recent dynamics of the agricultural commodity prices and some policy implications for policy makers farmers and global investors this study also suggests the directions for future studies

can contracts signal social norms experimental evidence we investigate whether incentive schemes signal social norms and thus affect behavior beyond their direct economic consequences a one shot principal agent experiment is studied where prior to contract choice principals are informed about the past actions of other agents and thus have more information about norms of behavior compared with a setting in which principals are uninformed agents exert substantially higher effort under a fixed wage contract when they are aware that an informed principal chose this contract the informed principal s choice apparently signals a norm not to exploit trust which leads to more trustworthy behavior this mechanism s robustness is explored in further experiments data as supplemental material are available at http dx doi org 10 1287 mnsc 2015 2336 this paper was accepted by uri gneezy behavioral economics

are gold and silver cointegrated new evidence from quantile cointegrating regressions this paper revisits the study on the long run relationship between gold and silver by escribano and granger 1998 we apply a quantile cointegration model to gold and silver prices and to prices of the corresponding futures contracts whereas cointegration models assuming a constant cointegrating vector fail to detect a cointegration relationship between gold and silver we are able to show that a nonlinear long run relationship exits the cointegrating vector is modelled as state dependent and time varying in our framework and the quantile cointegration estimates reveal substantial asymmetry in the relationship the results suggest that the pronounced role of precious metals as investment opportunities particularly in bubble like episodes and times of financial turmoil leads to comovement of gold and silver in these periods

why foreign economic assistance there is general agreement in the economics literature that resource flows among countries in response to market incentives enhance global economic efficiency and welfare in both rich and poor countries it has also been argued that in the presence of capital market imperfections the transfer of resources from developed country governments to the governments of developing countries on commercial terms either directly or through multilateral agencies can normally be expected to be welfare enhancing in both developed and developing countries 1 these arguments do not apply however to official development assistance that involves a substantial grant element two arguments have typically been used in support of transfers that include a grant component one set is based on the economic and strategic self interest of the donor country the second is based on the ethical or moral responsibility of the residents of wealthy countries toward the residents of poor countries both sets of arguments have been the subject of continuous challenge i argue in this article that neither the donor self interest nor the ethical responsibility argument can be rejected on logical or theoretical grounds i also assert that the empirical evidence in support of both the economic and the strategic self interest arguments is exceedingly weak the ethical responsibility arguments impose less burden on the empirical evidence but they are subject to continuous challenge by political theorists and moral philosophers donor self interest

tax policy regulated interest rates and saving abstract the paper evaluates tax policy options designed to reduce distortions to savings behavior that occur when administered interest rates are set beneath market equilibrium levels while the removal of controls on interest rates might be the best option political legal or institutional circumstances might well preclude this solution it suggests that consumption or sales taxes can be designed so that in the short term the rate of return to saving can be changed to approximate the market determined interest rate the main advantage of the measure is that it can provide a time to develop appropriate legal and institutional structures for financial deregulation and b an additional policy instrument that allows the burden of adjustment in a stabilization policy setting to be distributed over more than one instrument

sociopolitical instability and the behavior of savings in less developed countries the paper argues for the introduction of sociopolitical instability as a factor in explaining saving behavior it also provides empirical evidence in regard to the quantitative and qualitative relationship between these two variables the empirical results point towards an inverse relationship between sociopolitical instability and savings our estimates are based on a sample of 7 observations from 60 countries a new pooling procedure is used to address the problems of autocorrelation and heteroskedasticity

commodity futures and market efficiency we propose a comprehensive treatment of the leverage effect i e the relationship between returns and volatility of a specific asset focusing on energy commodities futures namely brent and wti crude oils natural gas and heating oil after estimating the volatility process without assuming any specific form of its behavior we find the volatility to be long term dependent with the hurst exponent on a verge of stationarity and non stationarity to overcome such complication we utilize the detrended cross correlation and the detrending moving average cross correlation coefficients and we find the standard leverage effect for both crude oils and heating oil for natural gas we find the inverse leverage effect additionally we report that the strength of the leverage effects is scale dependent finally we also show that none of the effects between returns and volatility is detected as the long term cross correlated one these findings can be further utilized to enhance forecasting models and mainly in the risk management and portfolio diversification

government spending and economic growth this study reviewed recent empirical studies providing fresh evidence of the impact of government spending on economic growth it is followed by a new theoretical synthesis and this as well as the other models are in turn subjected to empirical validation the empirical validation is conducted for both developed and less developed economies based on simultaneous equations as well as single equation models with or without adjusting for differences in th total factor productivity growth government size is estimated to have positive impact on economic growth in the short run but not in the intermediate run 25 years in this study

the relationship between crude oil spot and futures prices cointegration linear and nonlinear causality the present study investigates the linear and nonlinear causal linkages between daily spot and futures prices for maturities of one two three and four months of west texas intermediate wti crude oil the data cover two periods october 1991 october 1999 and november 1999 october 2007 with the latter being significantly more turbulent apart from the conventional linear granger test we apply a new nonparametric test for nonlinear causality by diks and panchenko after controlling for cointegration in addition to the traditional pairwise analysis we test for causality while correcting for the effects of the other variables to check if any of the observed causality is strictly nonlinear in nature we also examine the nonlinear causal relationships of vecm filtered residuals finally we investigate the hypothesis of nonlinear non causality after controlling for conditional heteroskedasticity in the data using a garch bekk model whilst the linear causal relationships disappear after vecm cointegration filtering nonlinear causal linkages in some cases persist even after garch filtering in both periods this indicates that spot and futures returns may exhibit asymmetric garch effects and or statistically significant higher order conditional moments moreover the results imply that if nonlinear effects are accounted for neither market leads or lags the other consistently videlicet the pattern of leads and lags changes over time

market efficiency of oil spot and futures a mean variance and stochastic dominance approach this paper examines the market efficiency of oil spot and futures prices by using both mean variance mv and stochastic dominance sd approaches based on the west texas intermediate crude oil data for the sample period 1989 2008 we find no evidence of any mv and sd relationships between oil spot and futures indices this infers that there is no arbitrage opportunity between these two markets spot and futures do not dominate one another investors are indifferent to investing spot or futures and the spot and futures oil markets are efficient and rational the empirical findings are robust to each sub period before and after the crises for different crises and also to portfolio diversification

savings rates and income distribution further evidence from ldcs a cross country test for the existence of kaldor effects in less developed countries is developed earlier attempts have been inconclusive and have led to a perception that the effect is unimportant it is argued that previous tests may have ben misspecified within a standard life cycle framework a savings rate function that also incorporates two distribution variables one involving measures of income inequalities across income classes and the other a broad measure of inequalities among sectors was specified and estimated the results indicate that regardless of the inequality measure employed some sort of kaldor effect may be at work this suggests that the traditional conflect between growth and equity warrants continued investigation

efficiency of crude oil markets evidences from informational entropy analysis abstract the role of crude oil as the main energy source for the global economic activity has motivated the discussion about the dynamics and causes of crude oil price changes an accurate understanding of the issue should provide important guidelines for the design of optimal policies and government budget planning using daily data for wti over the period january 1986 march 2011 we analyze the evolution of the informational complexity and efficiency for the crude oil market through multiscale entropy analysis the results indicated that the crude oil market is informationally efficient over the scrutinized period except for two periods that correspond to the early 1990s and late 2000s us recessions overall the results showed that deregulation has improved the operation of the market in the sense of making returns less predictable on the other hand there is some evidence that the probability of having a severe us economic recession increases as the informational efficiency decreases which indicates that returns from crude oil markets are less uncertain during economic downturns
