the relationship between regional natural gas markets and crude oil markets from a multi scale nonlinear granger causality perspective this study first decomposes the daily returns of regional gas and crude oil at different time scales using the ensemble empirical mode decomposition eemd method it then investigates the causality relationship between each pair of components at the different time scales by employing the linear and nonlinear granger causality tests for the original returns series this study finds that unidirectional linear granger causality exists from crude oil markets to north american and european gas markets however for nonlinear characteristics the crude oil and regional gas markets exhibit bidirectional nonlinear granger causality on the medium term time scale a bidirectional nonlinear spillover effect is found between the markets the long term trends for the markets suggest a significant linear relationship however no nonlinear spillover effect is found between the crude oil and regional gas markets

the cross cultural research imperative the need to balance cross national and intra national diversity this paper provides a brief overview of the evolution of comparative management theories paradigms and highlights the contribution of the cross vergence construct despite progress most studies of work values across countries continue to suffer from two primary limitations the first is the fallacious assumption of cultural homogeneity with nations given the growing diversity of the workforce within country intra national variations can often be as significant as cross national differences the second is the fallacious assumption of cultural stability over time since cultures evolve albeit slowly it is important to take these changes over time into consideration and be aware of the paradoxes inherent within any given society hence the paper calls for the need to balance cross national and intra national diversity in order to truly understand cross cultural phenomena and thus further improve the quality of cross cultural research

rockets and feathers the asymmetric speed of adjustment of uk retail gasoline prices to cost changes abstract the paper develops a quadratic quantity adjustment model to test the hypothesis put forward in the recent monopolies and mergers commission report that the speed of adjustment of uk retail gasoline prices to cost changes is more rapid when costs rise than when they fall and that the adjustment path is more concentrated around the mean value on the upswing using data from 1982 to 1989 evidence of faster and more concentrated responses to cost increases were found

the pervasive effects of family on entrepreneurship toward a family embeddedness perspective families and businesses have often been treated as naturally separate institutions whereas we argue that they are inextricably intertwined long term changes in family composition and in the roles and relations of family members have produced families in north america that are growing smaller and losing many of their previous role relationships such transformations in the institution of the family have implications for the emergence of new business opportunities opportunity recognition business start up decisions and the resource mobilization process we suggest that entrepreneurship scholars would benefit from a family embeddedness perspective on new venture creation d 2003 elsevier science inc all rights reserved

intra cultural variation evidence and implications for international business this paper discusses the methodological and theoretical significance of intra cultural variation icv the population distribution of a characteristic within a culture a monte carlo study shows that icv has substantial influence on the statistical power of cross cultural tests therefore studying icv is methodologically important if we are to understand inconsistent findings and design cross cultural studies with enough statistical power moreover an examination of the cultural means and icvs of 42 cultures shows that icv is as large as the variation of cultural means across cultures and its relationship to cultural means is not definite a model based on multiple disciplines is proposed to cast icv in a nomological net and to illuminate several avenues for future research practical implications are also discussed

electricity prices large scale renewable integration and policy implications abstract this paper investigates the effects of intermittent solar and wind power generation on electricity price formation in germany we use daily data from 2010 to 2015 a period with profound modifications in the german electricity market the most notable being the rapid integration of photovoltaic and wind power sources as well as the phasing out of nuclear energy in the context of a garch in mean model we show that both solar and wind power granger cause electricity prices that solar power generation reduces the volatility of electricity prices by scaling down the use of peak load power plants and that wind power generation increases the volatility of electricity prices by challenging electricity market flexibility

religious beliefs gambling attitudes and financial market outcomes this study investigates whether geographic variation in religion induced gambling norms affects aggregate market outcomes we conjecture that gambling propensity would be stronger in regions with higher concentrations of catholics relative to protestants consistent with our conjecture we show that in regions with higher catholic protestant ratios investors exhibit a stronger propensity to hold lottery type stocks broad based employee stock option plans are more popular the initial day return following an initial public offering is higher and the magnitude of the negative lottery stock premium is larger collectively these results indicate that religion induced gambling attitudes impact investors portfolio choices corporate decisions and stock returns

causality in quantiles and dynamic stock return volume relations abstract this paper investigates the causal relations between stock return and volume based on quantile regressions we first define granger non causality in all quantiles and propose testing non causality by a sup wald test such a test is consistent against any deviation from non causality in distribution as opposed to the existing tests that check only non causality in certain moment this test is readily extended to test non causality in different quantile ranges in the empirical studies of three major stock market indices we find that the causal effects of volume on return are usually heterogeneous across quantiles and those of return on volume are more stable in particular the quantile causal effects of volume on return exhibit a spectrum of symmetric v shape relations so that the dispersion of return distribution increases with lagged volume this is an alternative evidence that volume has a positive effect on return volatility moreover the inclusion of the squares of lagged returns in the model may weaken the quantile causal effects of volume on return but does not affect the causality per se

cognitive abilities and portfolio choice we study the relation between cognitive abilities and stockholding using the recent survey of health ageing and retirement in europe share which has detailed data on wealth and portfolio composition of individuals aged 50 in 11 european countries and three indicators of cognitive abilities mathematical verbal fluency and recall skills we find that the propensity to invest in stocks is strongly associated with cognitive abilities for both direct stock market participation and indirect participation through mutual funds and retirement accounts since the decision to invest in less information intensive assets such as bonds is less strongly related to cognitive abilities we conclude that the association between cognitive abilities and stockholding is driven by information constraints rather than by features of preferences or psychological traits

asymmetric and nonlinear pass through of crude oil prices to gasoline and natural gas prices in this article we use the recently developed nonlinear autoregressive distributedlags nardl model to examine the pass through of crude oil prices into gasoline and natural gas prices our approach allowsus to simultaneously test the short and long run nonlinearities through positive and negative partial sum decompositions of the predetermined explanatory variables it also offers the possibility to quantify the respective responses of gasoline and natural gas prices to positive and negative oil price shocks from the asymmetric dynamic multipliers the obtained results indicate that oil prices affect gasoline prices and natural gas prices in an asymmetric and nonlinear manner but the price transmission mechanism is not the same important policy implications can be learned from the empirical findings

social interaction and stock market participation we propose that stock market participation is influenced by social interaction in our model any given social investor finds the market more attractive when more of his peers participate we test this theory using data from the health and retirement study and find that social households those who interact with their neighbors or attend church are substantially more likely to invest in the market than non social households controlling for wealth race education and risk tolerance moreover consistent with a peer effects story the impact of sociability is stronger in states where stock market participation rates are higher

wavelet based test of co movement and causality between oil and renewable energy stock prices abstract we studied co movement and causality between oil and renewable energy stock prices using continuous and discrete wavelets firstly to obtain information on dynamic correlations over time and for different time scales from wavelet coherence and secondly to obtain information on linear and non linear granger causality in the time frequency domain for general and sectoral renewable energy indices for the period 2006 2015 our findings indicate that dependence between oil and renewable energy returns in the short run was weak but gradually strengthened towards the long run mainly for the period 2008 2012 our causality tests provide evidence against linear causality at higher frequencies and in favour of unidirectional and bidirectional linear causality at lower frequencies in contrast we found consistent evidence of non linear causality running from renewable energy indices to oil prices at different time horizons and mixed evidence of causality running from oil to renewable energy prices these results have potential implications for investors in terms of hedging and for policymakers in terms of policy support decisions regarding the development of renewable energy

married with children a collective labor supply model with detailed time use and intrahousehold expenditure information we propose a collective labor supply model with household production that generalizes an original model of blundell chiappori and meghir 2005 in our model adults individual preferences not only depend on own leisure and individual private consumption of market goods they also depend on the consumption of domestic goods which are produced by combining goods bought on the market with individuals time we apply our model to new and unique data on dutch couples with children the data contains detailed information about the spouses time use and the intrahousehold allocation of all expenditures our application uses a novel estimation strategy that builds upon the familiar two stage allocation representation of the collective model we obtain interesting and plausible empirical results spouses preferences depend on the consumption of domestically produced goods including children s welfare in addition pareto weights depend on variables like the individual wages and the share in the household s nonlabor income finally and perhaps surprisingly we do not nd evidence that mothers care more for their children than fathers this paper draws on data of the liss panel of centerdata special thanks go to marika de bruijne and arthur van soest who helped to construct the questionnaire and to guillaume schollier

causality in quantiles and dynamic relations in energy markets de tails matter abstract in this article we investigate the dynamic relations between crude oil price returns and a set of energy price returns namely diesel gasoline heating and the natural gas this is performed by means of granger non causality tests for us closing spot prices over the period from january 1997 to december 2017 in previous studies this has been done by testing for the added predictive value of including lagged returns of one energy price in predicting the conditional expectation of another in this paper we instead focus on different ranges of the full conditional distribution and thus market states within the framework of a dynamic quantile regression model and identify the quantile ranges from which causality arises the results constitute a richer set of findings than what is possible by just considering a single moment of the conditional distribution which can be useful for implementing better substitution investment strategies and effective policy interventions we find several interesting uni directional dynamic relations between the employed energy price returns especially in the tail quantiles but also bi directional causal relations between energy price returns for which the classical granger non causality test suggests otherwise our results are robust to alternative measures of the price of oil and different data frequencies

price relationships in the petroleum market an analysis of crude oil and refined product prices in this paper the relationships between crude oil and refined product prices are investigated in a multivariate framework this allows us to test several partly competing assumptions of earlier studies in particular we find that the crude oil price is weakly exogenous and that the spread is constant in some but not all relationships moreover the multivariate analysis shows that the link between crude oil prices and several refined product prices implies market integration for these refined products this is an example of supply driven market integration and producers will change the output mix in response to price changes

individual values and household finances we create individual cultural values measures for households and show that this is an important determinant of their financial behaviour to date personal cultural values have only been indirectly measured through religion and trust but these are at best an approximation of true cultural values applying a holistic framework from the world values survey wvs we create individual measures of cultural values and show that the self expression values of this framework are positively associated with households financial decisions examining the individual cultural values that make up the wvs model we further show that happiness trust and playing an active role in society are individually important determinants of household financial decision making our study shows that cultural values can be brought from a generalized national level to the individual level in order to improve our understanding of household financial decision making

the employment effects of the social security earnings test we investigate the impact of the social security annual earnings test aet on the employment decisions of older americans the aet reduces social security benefits by one dollar for every two dollars earned above the exempt amount using a differences in differences design we find that the employment rate of those predicted to become subject to the aet decreases substantially relative to those not predicted to become subject to it the point estimates suggest that the aet reduces the employment rate of americans aged 63 64 by at least 1 2 percentage points

nonlinear dependence between stock and real estate markets in china the causality between the real estate and stock markets of china remains a mystery in the literature this paper investigates the non linear causal relationship between real estate property and stock returns in china from the perspective of conditional quantiles the results of the quantile causality test suggest a significant causal relationship between these two markets especially in the tail quantile

egalitarianism and international investment abstract this study identifies how country differences on a key cultural dimension egalitarianism influence international investment flows a society s cultural orientation toward egalitarianism is manifested by intolerance for abuses of market and political power and a desire for protecting less powerful actors we show egalitarianism to be based on exogenous factors including social fractionalization dominant religion circa 1900 and war experience from the 19th century we find a robust influence of egalitarianism distance on cross national flows of bond and equity issuances syndicated loans and mergers and acquisitions an informal cultural institution largely determined a century or more ago egalitarianism exercises its effect on international investment via an associated set of consistent contemporary policy choices but even after controlling for these associated policy choices egalitarianism continues to exercise a direct effect on cross border investment flows likely through its direct influence on managers daily business conduct

the message in north american energy prices how similar is the price behavior of north american natural gas fuel oil and power prices using current state of the art econometric methodology we explore the degree of shared trends across north american energy markets across these markets there appear to be effective arbitraging mechanisms for the price of natural gas and fuel oil but not for the price of electricity

do gasoline prices respond asymmetrically to crude oil price changes the authors test and confirm that retail gasoline prices respond more quickly to increases than to decreases in crude oil prices among the possible sources of this asymmetry are production inventory adjustment lags and market power of some sellers by analyzing price transmission at different points in the distribution chain the authors attempt to shed light on these theories spot prices for generic gasoline show asymmetry in responding to crude oil price changes which may reflect inventory adjustment effects asymmetry also appears in the response of retail prices to wholesale price changes possibly indicating short run market power among retailers

the effects of investing social security funds in the stock market when fixed costs prevent some households from holding stocks with fixed costs of participating in the stock market consumers with high income will participate in the stock market but consumers with lower income will not participate if a fully funded defined contribution social security system tries to exploit the equity premium by selling a dollar of bonds per capita and buying a dollar of equity per capita consumers who save but do not participate in the stock market will increase their consumption thereby reducing saving and capital accumulation calibration of a general equilibrium model indicates that this policy could reduce the aggregate capital stock substantially by about 50 cents per capita
