blurring the boundaries the interplay of gender and local communities in the commercialization of social ventures this paper examines the critical role of gender in the commercialization of social ventures we argue that cultural beliefs about what is perceived to be appropriate work for each gender influence how founders of social ventures incorporate commercial activity into their ventures specifically we argue and show that although cultural beliefs that disassociate women from commercial activity may result in female social venture founders being less likely to use commercial activity than their male counterparts these effects are moderated by cultural beliefs about gender and commercial activity within founders local communities the presence of female business owners in the same community mitigates the role of founders gender on the use of commercial activity we examine these issues through a novel sample of 584 social ventures in the united states we constructively replicate and extend these findings with a supplemental analysis of a second sample the full population of new nonprofit organizations foun

time to share the load gender differences in household responsibilities and business profitability this paper uses data from 2408 micro and small businesses in ecuador to study business profit differentials by gender the results point to unpaid work time devoted to household chores child care and care for the elderly as the largest single factor explaining 33 of the difference in profits observed between male and female run businesses when comparing male and female business owners with similar business and personal characteristics the difference in business profits disappears the results point to initial endowments rather than returns on those endowments as the reason why female run businesses are less profitable also they indicate that male and female entrepreneurs are equally effective as managers provided they have access to the same resources including time

s p 500 cash stock price volatilities s p 500 stock return volatilities are compared to the volatilities of a matched set of stocks after controlling for cross sectional differences in firm attributes known to affect volatility no significant difference in volatility is observed between 1975 and 1983before the start of trade in index futures and index options since then s p 500 stocks have been relatively more volatile the difference is statistically but not economically significant the relative increase occurs primarily in daily returns and only to a lesser extent in longer interval returns other factors besides the start of derivative trade could be responsible for the small increase in volatility stock price volatility has received much attention in the popular press over the last few years especially since the october 19 1987 stock market crash the rise in volatility has alarmed investors regulators and the public in general some suggest that the start of trade in stock index futures and index options increased speculative activity that in turn destabilized cash markets causing higher volatility large trading activity in the derivative contracts makes the suggestion plausible volume in index futures and index options increased dramatically since their introductions in 1982 and 1983 by 1987 the average daily dollar volume in the s p 500 futures contracts alone exceeded the dollar volume of cash s p 500 trade by a factor of about two while the dollar value of the daily net change in total open interest is about 8 of s p 500 stock dollar volume speculative trade in futures and options frequently is accused of destabilizing underlying cash markets the charge has been made for more than a century in the agricultural precious metal and currency markets recent evidence by french and roll 1986 showing stock variance to be strongly related to trading session hours heightens these concerns unfortunately theoretical analyses of whether speculative trade destabilizes cash markets lead to conflicting conclusions depending on what assumptions are made 1 school of business administration university of southern california and office of economic analysis u s securities and exchange commission i wish to thank mary denny mcsweeny and steve hornstein for their valuable research assistance and the referee and editor for their many suggestions and insights the opinions expressed in this paper do not necessarily reflect those of the u s securities and exchange commission or those of the author s colleagues on its staff an increase in well informed speculative trade has two opposite effects on measured volatility it decreases volatility due to order flow imbalances caused by uninformed traders because informed traders provide liquidity in such events and it increases volatility due to new fundamental information since the information which is assumed to be generated at discrete time intervals is impounded into

marching to the beat of the drum the impact of the pace of life in us cities on entrepreneurial work effort founders face a variety of challenges while working to establish a viable start up in order to successfully overcome the many pressures that they face founders must make difficult choices about how to allocate their time and how much effort to exert in their ventures these founders are also embedded in a broader social context and their efforts are influenced by external conditions in this study we examine one particular social condition pace of life and its relationship on entrepreneurial work effort we argue that the pace of life in the region where founders launch and run their ventures affects their work effort over and above other individual and firm level characteristics we also argue that this direct relationship can strengthen or weaken depending on founding team size or entrepreneurial experience our longitudinal analyses of nearly 2600 us new ventures from 2004 to 2011 support our arguments our work advances prior research on the determinants of entrepreneurial work effort enhances the literature on social norms and entrepreneurial action and provides additional insights into the multilevel influences of entrepreneurial activity while entrepreneurs are commonly perceived as non conformists who march to the beat of their own drum we find evidence suggesting that regional pace of life actually sets the tempo for business owners and influences the amount of effort that they allocate to their ventures

agricultural price instability a survey of competing explanations and remedies there are two explanations for agricultural price dynamics one follows cobweb logic and models fluctuations driven by expectation errors but emphasises that these expectations create complex dynamics and possibly chaos the other stems from the rational expectations tradition of dynamics driven by real shocks the empirical evidence tends to support the latter but is not conclusive the rational expectations model generates an optimal dynamic path from which no improvement can be expected from public intervention however if we take account of all the potential market failures in agricultural markets and especially in developing countries this conclusion might require some qualifications although an appropriate policy design for stability has still to be achieved this paper surveys the positive and normative literature on agricultural prices highlighting empirical evidence and identifying remaining unresolved issues

the impact of wind power generation on the electricity price in germany abstract this paper investigates the relationship between intermittent wind power generation and electricity price behaviour in germany using a garch model i evaluate the effect of wind electricity generation on the level and the volatility of the electricity price in an integrated approach the results show that variable wind power reduces the price level but increases its volatility this paper s results also indicate that regulatory change has stabilised the wholesale price the electricity price volatility has decreased in germany after a modification of the marketing mechanism of renewable electricity this gives confidence that further adjustments to regulation and policy may foster a better integration of renewables into the power system

financial innovation and information the role of derivatives when a market for information exists we study the effects of financial innovation in a model of endogenous information acquisition we determine the conditions under which the introduction of a derivative written on an existing stock increases or decreases the incentive to purchase information we show that financial innovation produces some effects which hold across informational structures and others which differ the former coincide with the few empirical results that are robust in the literature effects on prices risk premia and volatility while the latter coincide with the ones that differ experiment by experiment effects on volume correlation between volume and volatility and market informational efficiency copyright 2002 oxford university press

price discovery and learning during the preopening period in the paris bourse before the opening of the paris bourse traders place orders and indicative prices are set this offers a laboratory to study empirically the t tonnement process through which markets discover equilibrium prices since preopening orders can be revised or canceled before the opening indicative prices could be noise we test this against the hypothesis that preopening prices reflect learning early in the preopening the noise hypothesis is not rejected as the opening gets closer the informational content and efficiency of prices increase and the learning hypothesis is not rejected we also propose a gmm based estimate of the speed of learning

gender as a determinant of small business performance insights from a british study the performance of small businesses that is the ability of small firms to contribute to job and wealth creation through business start up survival and growth has been an important area of policy and academic debate in the 1980s surprisingly little has been written about gender and small business performance our literature search revealed only a small number of studies of any substance on this subject though over forty made some mention of it most studies shied away from direct examination of quantitative performance measures such as jobs created sales turnover annual growth tending to concentrate on qualitative measures of success or failure the paper examines small business performance and gender using data obtained from a survey of 600 300 women 300 men scottish and english small business ownermanagers part of a three year study on the impact of gender on small business management analyses suggest that the relationship between gender and small business performance is complex but that gender still appears to be a significant determinant even after other key factors are controlled for

magnitude and persistence of extreme risk spillovers in the global energy market a high dimensional left tail interdependence perspective abstract this paper studies the magnitude and persistence of extreme risk spillovers among stock returns of 124 energy companies worldwide between january 2006 and june 2019 as well as the corresponding firm specific determinants of firms extreme risk spillovers the high dimensional nonparametric method the coefficient of tail interdependence cti enables us to make better use of available information and to evaluate risk spillovers more precisely moreover we use spatial panel models that consider spatial heterogeneity among firms to explore the determinants of the risk spillovers the empirical findings from a study of energy firms risk spillover effects verify the necessity of persistence measurement also the most systemically risky energy companies are not necessarily the largest and some small firms can also generate large risk spillovers when they are in distress which indicates that determinants other than firm size could also affect the spillover effect such as business complexity and geographic location our regression results suggest that the extreme risk spillover of the energy companies exhibits significant heterogeneity in terms of business and region which deserves more attention for energy risk management the estimates can be used for making portfolio decisions and designing regulatory policies

gender differences in firm performance evidence from new ventures in the united states abstract prior studies examining the performance of female and male owned firms have generally reported that female owned firms underperform male owned firms however it is conceivable that the performance measures used by previous studies and or their inability to control for key demographic differences may have contributed to this finding for example few studies use size adjusted performance measures and yet we know that female owned firms tend to be smaller than their male counterparts similarly risk is typically not considered even though evidence suggests that women tend to be more risk averse than men we use a longitudinal five year database of more than 4000 new ventures that began operations in the u s in 2004 to determine whether potential differences in the performances of female and male owned firms disappear when appropriate performance measures are used and important demographic differences are controlled for in the models the performance measures we examine include 4 year closure rates return on assets roa and a risk adjusted measure sharpe ratio univariate test results confirm our expectation based on both liberal and social feminist theory that there is no difference in the performance of female and male owned new ventures provided performance is appropriately measured further these results are supported by our multivariate analyses which control for demographic differences such as industry experience and hours worked our findings should be of interest to researchers financiers advisors and policy makers perhaps more importantly our findings should also ensure that women who are contemplating starting a new venture are not discouraged from doing so by a false belief that new ventures initiated by women are less likely to succeed than those initiated by men

price volatility trading volume and market depth evidence from futures markets the relations between volume volatility and market depth in eight physical and financial futures markets are examined evidence suggests that linking volatility to total volume does not extract all information when volume is partitioned into expected and unexpected components the paper finds that unexpected volume shocks have a larger effect on volatility further the relation is asymmetric the impact of positive unexpected volume shocks on volatility is larger than the impact of negative shocks finally consistent with theories of market depth the study shows large open interest mitigates volatility

analyzing the impact of futures trading on spot price volatility evidence from the spot electricity market in france and germany abstract this paper examines the impact of the introduction of electricity futures on the spot price volatility of the french powernext and german eex electricity markets as well as the degree of their price correlation over the period 2002 2011 our working hypotheses were tested based on a bivariate vecm garch model the results indicate that the introduction of futures contracts in the french electricity market as well as the launch of the joint futures market in these countries in 2009 has decreased spot price volatility however this effect was not as explicit for the german market due to data specificities other interesting results are the german market dominates and leads the long run price relationship the impact of cooling needs on demand is greater than the impact of heating needs there is a substantial systematic pattern of electricity prices and their respective volatilities during weekdays and holidays overall results are supportive of policy making at the european commission regarding electricity market integration

forecasting volatility of the u s oil market abstract we examine the information content of the cboe crude oil volatility index ovx when forecasting realized volatility in the wti futures market additionally we study whether other market variables such as volume open interest daily returns bid ask spread and the slope of the futures curve contain predictive power beyond what is embedded in the implied volatility in out of sample forecasting we find that econometric models based on realized volatility can be improved by including implied volatility and other variables our results show that including implied volatility significantly improves daily and weekly volatility forecasts however including other market variables significantly improves daily weekly and monthly volatility forecasts

businesses without glamour an analysis of resources on performance by size and age in small service and retail firms abstract research on factors influencing performance in new and small companies is extensive earlier work found that strategies e g cost quality differentiation etc affected performance contingent on industry conditions the environment and the entrepreneur s background although this work provides a solid basis for understanding differences in entrepreneurial performance some firms are limited in their choices of strategy due to size age or industry often these firms are in industries where entry barriers are low and competitive advantages are easily imitated small service and retail businesses operate in sectors where these conditions are apparent comprising more than 50 of all small firms they require minimal start up investments but face intense competition lacking the glamour of high innovation high growth firms service and retail companies are at the end of the value chain their fortunes rising and falling as a result of the direct influence of the owner founder hence performance variation may be better explained by the capabilities of the firm or individual competencies of the owner founder that is the resource base and resource combinations rather than strategy the strategic importance of an organization s resources and capabilities is the foundation of resource based theory resources are tangible and intangible assets tied to the firm in a relatively permanent fashion their combinations are heterogeneous and form the basis for product market strategies studies of resources strategies and performance are emerging in the entrepreneurial area research shows that various resources in concert with different strategy types can lead to above average performance over the business life cycle and that combinations of resources are related to survival yet the vast majority of work focuses on high growth high tech or manufacturing businesses less is known about the relationships of resources to performance in less glamorous sectors in these small service and retail businesses we speculate that resources in particular human and organizational resources may play a greater role in explaining performance than strategy further as other authors have suggested it is expected that the combinations of these resources will vary across age and size this study examines the influence of human and organizational resources on performance in a sample of 195 service and retail firms operating in central new jersey using a structured questionnaire all companies utilized a focus strategy either focused cost or focused differentiation and employed a minimum of 3 to a maximum of 100 employees all measures had theoretical and or empirical precedent and were tested statistically for reliability we used factor analysis to reduce the independent variables to two human resource variables owner resources and commitment one organizational resource variable comprised of planning systems and staff skills and one strategy variable focused cost and focused differentiation control variables were business age business size environmental benignness and industry growth the dependent variable performance was measured in two ways net cash flow and log of growth in employees over 3 years the study first examined whether strategy or resources had a greater influence on performance results showed that strategy influenced performance less than human and organizational resources both individually and interactively the influence of owner resources background and attitudes on net cash flow was stronger than on growth where the only significant variable was industry market growth to analyze effects of resources on performance by size we divided the sample by size groupings selecting the smallest maximum five employees and largest quartiles minimum 16 employees which were comprised of 55 and 50 companies respectively these analyses showed that owner resources commitment and organizational resources contributed positively to net cash flow in very small firms however interactive effects of these resource combinations were negative for instance owner resources and organizational resources together and organizational resources and commitment together resulted in less positive cash flow than when analyzed separately this implies that different resource combinations can have negative influences in these very small firms we examined age effects in the same manner as size dividing the sample into age group quartiles and conducting an analysis only for very young fewer than 5 years and very old minimum 19 years groups which comprised 54 and 52 companies respectively these analyses showed that although growth was more rapid among the youngest firms there were no distinctive resource based correlates to growth in either age group substantive increases in formalized systems and procedures were not apparent among the oldest of these companies compared with the youngest contrary to previous work showing the evolution of these over business life cycles results of this study are applicable only in the context of service and retail firms and readers should note this sample was nonrandom and geographically concentrated our purpose was not to predict but describe associations between resources and performance this study shows that for firms in competitive industries at the end of the value chain type of strategy is less important than resource combinations for certain types of performance human and organizational resources are associated with more positive cash flow whereas industry and market factors are related to growth these results imply that firms seeking growth are best served by selecting and entering growth markets and industries on the other hand if strong positive cash flows are the primary objective attention to combinations of resources is more important for instance owner founders having a strong business and managerial background and industry experience will need less formalized systems whereas those owner founders with weaker managerial resources might benefit from more formalized procedures and skilled staff

a broadened causality in variance approach to assess the risk dynamics between crude oil prices and the jordanian stock market within the new developed causality in variance approach this paper builds up a broad methodological framework to more accurately capture the risk spillover effects between global oil prices and jordanian stock market returns during the period 1 march 2003 31 january 2014 the sample period is divided on the basis of the 2008 financial crisis into pre crisis and post crisis periods results for the pre crisis period show a lack of risk spillovers between global oil and the jordanian stock market after the crisis however we find evidence for one way risk spillover running from the oil market these findings have implications for the design of appropriate asset allocation and regulatory policies to manage risk spillover effects

who lends to riskier and lower profitability firms evidence from the syndicated loan market this paper exploits a unique data set on bank firm relationships based on syndicated loan deals to examine the effect of banks credit risk and capital on firms risk and performance our data set is a multilevel cross section which essentially allows controlling for all bank and firm characteristics through respective fixed effects thus avoiding concerns regarding omitted variables we find that banks with higher credit risk are associated with more risky firms with lower profitability and market value in turn we find that banks with higher risk weighted capital ratios lend to riskier firms with less market value our results are indicative of a strong adverse selection mechanism and highlight the need to monitor the risky banks more closely especially as we consider large and influential syndicated loan deals

the relationship between firm growth size and age estimates for 100 manufacturing industries this study uses a sample of all firms operating in 100 manufacturing industries to examine some aspects of firm dynamics it finds that firm growth the variability of firm growth and the probability that a firm will fail decrease with firm age it also finds that firm growth decreases at a diminishing rate with firm size even after controlling for the exit of slow growing firms from the sample gibrat s law therefore fails although the severity of the failure decreases with firm size copyright 1987 by blackwell publishing ltd

speculative intensity and spot and futures price variability this paper develops a simultaneous stochastic rational expectations model of futures and spot price determination using the model we find that increases in what we term speculative intensity increase spot price variability arising from storage cost shocks but decrease spot price variability arising from demand shocks in contrast increases in speculative intensity unambiguously decrease futures price variability regardless of the underlying source of disturbances we are able to develop these comparative static results because the model has a unique equilibrium

discontinuance among new firms in retail the influence of initial resources strategy and gender abstract women owned businesses represent one of the fastest growing segments of the u s economy their rate has increased more than six fold since 1970 despite this growth rate the number of firms owned by women still lags behind that of men and the sales and income of women owned firms are significantly lower than those of men owned firms the discrepancy between the number of businesses owned by women and men and their economic success has been a popular theme among researchers some have suggested that performance differentials result from disparate structural positions women and men occupy in work and society whereas others attribute the differences to deep rooted interpersonal orientations this study examines whether the performance differences can be explained by variations in initial resources and founding strategy we test whether women have fewer start up resources and if they do whether they can compensate for these deficiencies through their founding strategy recent work in social psychology argues that strategic choice is shaped by experiences to which individuals have been subjected and that women and men have fundamentally different socialization experiences we test the assumption that if the strategy that women owners adopt exploits the unique capabilities they derive from their socialization they can improve the performance of their firms and ward off discontinuance we examine the discontinuance pattern of 203 new firms in the retail industry this industry was selected because women entrepreneurs often choose to operate in this industry giving us a basis for comparing women owned and men owned firms we classify the firms into six strategy archetypes the arche types range from a broad focus where founders emphasize multiple strategic foci simultaneously to narrowly targeted differentiation strategies we assume that the experiential base of women entrepreneurs limits their successfully executing pricing strategies we hypothesize that women led firms decrease the odds of discontinuing by adopting one of two strategy types 1 narrow differentiation strategies that seek to satisfy a narrow segment of the market and that do not rely on pricing or 2 broad generalists strategies that emphasize service and quality but not pricing and take advantage of women s capability for handling multiple stakeholders simultaneously the results offer support for using an integrative model to explain the performance of women owned firms women owned firms have higher odds of discontinuing than men owned firms and women appear to have fewer resources to start their businesses women owners were less likely to have instrumental experience from working in the retail industry and start their businesses on a smaller scale then men but were no less likely then their male counterparts to have access to credit from formal financial institutions or to be disadvantaged by starting fewer other new businesses despite some apparent situational disadvantage resource deficiencies do not appear to affect the odds of women owned businesses discontinuing as much as they do men owned initiatives the findings indicate support for the supposition that women owners can use founding strategy to decrease the odds of discontinuing business a broad generalists strategy that represents a multi focused approach was found to benefit women owned businesses most overall the results suggest that men use prior business experience and human capital to affect the survival status of their businesses women appear to find strategic choice more beneficial future research is recommended to further elaborate the integrative model special attention should be given to developing alternatives to measures traditionally used in gender research many researchers charge that those typically used reflect male derived measures similarly greater attention should be given to understanding why the scale of women owned businesses at start up is substantially smaller than that of men since scale has been shown to be related to subsequent growth and survival

new firms societal contribution versus survival potential abstract new business firms are now considered a major source of new jobs economic growth technical innovation and economic flexibility they may provide a major strategic advantage for the united states in world competition a more complete precise understanding of the dynamics of new firm development their societal contributions and factors affecting their survival has considerable policy and managerial significance a study of new firm contributions and survival was completed to determine whether the same factors would account for both they do not the research began with a substantial body of descriptive information on 551 new firms initiated in minnesota between 1978 and 1984 the initial data were collected in the summer of 1984 a one year follow up was completed in 1985 to determine new firm survival the sample was representative of all major industry sectors and all regions of the state about 60 were located in the minneapolis st paul urban area attempts to predict current 1984 contributions indicated that age was not a significant factor older new firms did not contribute more than younger new firms the developmental pattern primarily the average annual growth rate was highly related to sales or jobs provided in 1984 next most significant was the industry of the new firm manufacturing distributive services and business producer service new firms provided more significant contributions the one year follow up was able to determine the survival status of 548 of the 551 firms slightly less than 10 48 had not survived major factors related to survival appeared to be age high death rates at 2 3 years and attention to financial matters

testing the female underperformance hypothesis most previous studies have found evidence at the aggregate level that female entrepreneurs underperform relative to their male counterparts this study conducts a comprehensive test of this finding the test is conducted on a large swedish sample of 4200 entrepreneurs 405 females with 1 to 20 employees in all sectors of the economy our study confirms the results of several previous studies that female entrepreneurs tend to underperform relative to men when the data is examined at the most aggregate level at the same time our data reveals sharp structural differences between male and female entrepreneurs in an extensive multi variate regression with a large number of controls it turns out that female underperformance disappears for three out of four performance variables the only exception is sales no gender difference is found for profitability a more detailed analysis reveals that the evidence of female underperformance is much weaker in larger firms and nonexistent in firms with only one employee if it is true that female entrepreneurs on average have weaker preferences for sales growth while we consistently find that they do not underperform in terms of profitability our study provides no support for female underperformance given differences in preferences

on the origins of entrepreneurship evidence from sibling correlations we assess the broad importance of family and community background for entrepreneurship outcomes we go beyond traditional intergenerational associations by estimating sibling correlations in unincorporated and incorporated entrepreneurship using register data from sweden sibling correlations range from 20 to 50 they are consistently higher for more committed and incorporated entrepreneurship than for less committed or unincorporated entrepreneurship they are also higher for brothers than sisters we then assess what factors drive these correlations parental entrepreneurship neighborhoods shared genes and financial resources help explain these high correlations whereas immigration status family structure and sibling peer effects have a limited contribution the higher correlation for incorporated versus unincorporated entrepreneurship is explained mainly by the type of parental entrepreneurial engagement and financial resources while the gap between brother and sister correlations in unincorporated entrepreneurship is largely driven by the geographic concentration of male dominated industries

relationships between oil price shocks and stock market an empirical analysis from china this paper investigates the interactive relationships between oil price shocks and chinese stock market using multivariate vector auto regression oil price shocks do not show statistically significant impact on the real stock returns of most chinese stock market indices except for manufacturing index and some oil companies some important oil price shocks depress oil company stock prices increase in oil volatility may increase the speculations in mining index and petrochemicals index which raise their stock returns both the world oil price shocks and china oil price shocks can explain much more than interest rates for manufacturing index

rationalizable strategic behavior the notion of equilibrium proposed by nash 19 has come to play a dominant role in economic applications of noncooperative games while analyses of nash equilibria have unquestionably contributed to our understanding of economic behavior it would be unreasonably optimistic to maintain that nash solved the problem of noncooperative strategic choice there is a small literature beginning with ellsberg 6 and a much larger oral tradition which argues that nash behavior is neither a necessary consequence of rationality nor a reasonable empirical proposition in this paper i take the view that although there may be various reasons why an agent might select a nash strategy the notion of an equilibrium has little intrinsic appeal within a strategic context when an agent reaches a decision in ignorance of the strategies adopted by other players rationality consists of making a choice which is justifiable by an internally consistent system of beliefs rather than one which is optimal post hoc this point of view is not original indeed most serious justifications of the nash hypothesis embrace such an approach arguing that agents will expect the game to yield a nash outcome and consequently will choose their equilibrium strategies nevertheless when we think in terms of maximizing utility subject to expectations rather than realizations it becomes clear that the nash hypothesis far from being a consequence of rationality arises from certain restrictions on agents expectations which may or may not be plausible depending upon the game being played we are then quite naturally led to ask are there any restrictions of individuals expectations and hence choices which are required by rationality alone rather than by subjective plausibility this paper is concerned with defining justifying characterizing and refining a criterion for rational strategic choice which i label rationalizability

women business owners in traditional and non traditional industries abstract small businesses continue to grow in importance to the national economy according to the small business administration america s 22 million small businesses generate more than half of the nation s gross domestic product and are the principal source of new jobs the national foundation for women business owners reported that between 1987 and 1994 the number of women owned businesses grew by 78 and women owned firms accounted for 36 of all firms although the growth in the number of women owned businesses is encouraging the size of such businesses remains small in terms of both revenues and number of employees especially in comparison to male owned businesses one explanation for this disparity is that female business ownership is concentrated primarily in the retail and service industries where businesses are relatively smaller in terms of employment and revenue as opposed to high technology construction and manufacturing one of the most fruitful streams of research in women s occupational choice has been based on social learning theory specifically self efficacy has been found to relate to both type and number of occupations considered by college men and women and with regard to traditional and non traditional occupations entrepreneurship researchers have also used social learning theory to study entrepreneurial intentions this study builds on that background of women s career development and entrepreneurial intentions to examine differences between traditional and non traditional women business owners we examine 170 women business owners in various traditional and non traditional businesses in utah and illinois questionnaires were the primary method of collecting data in addition to 11 in depth interviews from a sample of the survey respondents using a careers perspective based on social learning theory we hypothesized that women in these two different categories of industries would differ on levels of self efficacy toward entrepreneurship or venture efficacy their career expectations and their perceived social support a second analysis was also done that explored the relationship between the same independent variables and success or performance of the business the results offer support for using this integrative model to understand differences between women in traditional and non traditional industries the first analysis revealed that significant differences exist between the two groups on several of the independent variables traditional business owners had higher venture efficacy for opportunity recognition higher career expectations of life balance and security and they reported that the financial support received from others was more important to them than those in non traditional businesses on the other hand the non traditional owners had higher venture efficacy for planning and higher career expectations for money or wealth than the traditional group the second analysis explored whether success as measured by sales was affected by differences in venture efficacies career expectations or perceived support received by women in traditional businesses as compared to those in non traditional ones this analysis revealed that traditional women business owners might have different factors that contribute to their success than non traditional owners specifically for the traditional owners venture efficacies for opportunity recognition and economic management as well as the career expectation of autonomy and money or wealth were positively related to sales for the same group efficacy toward planning and the need for security were negatively related to sales for the non traditional women venture efficacy toward planning and the career expectation of autonomy were positively related to sales while the expectation of money or wealth was negatively related also for the same group the perceived importance of the emotional and financial support was negatively related to sales in the past most of the entrepreneurial research has used predominantly male samples of entrepreneurs those that include women entrepreneurs generally are comparative between men and women this study s comparison of two groups of women entrepreneurs offers a unique contribution to the field future research is recommended to further understand how venture efficacy and career expectations affect the decision to start a new business in a particular industry it would be particularly beneficial to study venture efficacy and career expectations of prospective women entrepreneurs prior to the start of the business similarly greater attention should be given to understanding how venture efficacy develops in different individuals

crude oil prices and sectoral stock returns in jordan around the arab uprisings of 2010 abstract in this paper we test for mean and variance causality between world oil prices and sectoral equity returns in jordan before and after the arab uprisings that started in 2010 the testing methodology is based on the sample of cross correlation functions that are computed from the standardized residuals of a garch process our results show that the influence is not uniform across the equity sectors the oil return shocks significantly impact the financials and the services sectors while its effect is insignificant on the industrials sector this result is more pronounced in the period that follows the arab uprisings in terms of risk transfer we find that oil is a negligible risk factor however there is still a significant evidence of risk transmission to the industrials sector particularly during the arab uprisings period these results represent a unique information transmission mechanism that is useful for risk management and portfolio diversification

futures trading information and spot price volatility evidence for the ftse 100 stock index futures contract using garch abstract this paper examines the impact of trading in the ftse 100 stock index futures on the volatility of the underlying spot market to examine the relationship between information and volatility as subject neglected in previous studies the garch family of techniques is used the results suggest that futures trading has led to increased volatility but that the nature of volatility has not changed post futures the finding of price changes being integrated pre futures but being stationary post futures implies that the introduction of futures has improved the speed and quality of information flowing to the spot market

derivative securities and cash market stability this study investigates the effect of introducing interest rate futures and options on the price variances in related financial cash markets standard research approaches to this issue relate cash price stability before the introduction of futures and options trading to cash price stability after trading in the derivative security begins however controlling for the additional factors that may also effect cash markets is difficult the approach employed here to deal with this obstacle is motivated by recent theoretical research relating cash and futures markets but hitherto not operationalized to empirically test for a relationship between the markets varying parameter models of 1 the demand for short term treasury securities 2 the demand for large time deposits and 3 the supply of large time deposits are specified such that changes in the parameters imply changes in the volatility of the cash price these parameters are modelled as functions of the trading volume of interest rate futures and o

the death of firms exploring the effects of environment and birth cohort on firm survival in sweden this paper investigates the death of firms and seizes a long term perspective it investigates the life spans of nearly 2 200 firms in seven birth cohorts of swedish joint stock companies founded during seven separate years between 1899 and 1950 research has traditionally emphasized individual and micro oriented factors in explaining post entry performance or has often focused on the influence of firm specific structural factors firm age and size a less attended field recognizes environmental forces this paper focuses on the interaction between the micro and macro levels and combines structural and environmental factors employing a cohort approach it relates firm survival to firm age and size as well as to the effect of cohort affiliation and environmental change over time period effects during macroeconomic expansion the risk of death decreases cohort effects are also evident firms founded during times of economic crisis exhibit lower survival rates consequently cohort affiliation and environmental forces i e period effects can explain differences in death rates in different firm populations

the value of human and social capital investments for the business performance of startups we investigate the manifold posed question to what extent does investment in human and social capital besides the effect of talent enhance entrepreneurial performance we distinguish between three different performance measures survival profits and generated employment on the basis of the empirical analysis of a rich dutch longitudinal data set of firm founders we conclude that specific investments indeed affect the three performance measures substantially and significantly specific attention is paid to the unobserved talent bias moreover the effect of the emergence of so called knowledge industries is explored

rationalizable strategic behavior and the problem of perfection this paper explores the fundamental problem of what can be inferred about the outcome of a noncooperative game from the rationality of the players and from the information they possess the answer is summarized in a solution concept called rationalizability strategy profiles that are rationalizable are not always nash equilibria conversely the information in an extensive form game often allows certain unreasonable nash equilibria to be excluded from the set of rationalizable profiles a stronger form of rationalizability is appropriate if players are known to be not merely rational but also cautious what constitutes rational behavior in a noncooperative strategic situation this paper explores the issue in the context of a wide class of finite noncooperative games in extensive form the traditional answer relies heavily upon the idea of nash equilibrium nash 17 the position developed here however is that as a criterion for judging a profile of strategies to be reasonable choices for players in a game the nash equilibrium property is neither necessary nor sufficient some nash equilibria are intuitively unreasonable and not all reasonable strategy profiles are nash equilibria the fact that a nash equilibrium can be intuitively unattractive is well known the equilibrium may be imperfect introduced into the literature by selten 20 the idea of imperfect equilibria has prompted game theorists to search for a narrower definition of equilibrium while this research some of which will be discussed here has been extremely instructive it remains inconclusive theorists often agree about what should happen in particular games but to capture this intuition in a general solution concept has proved to be very difficult if this paper is successful it should make some progress in that direction the other side of the coin has received less scrutiny can all non nash profiles really be excluded on logical grounds i believe not the standard justifications for considering only nash profiles are circular in nature or make gratuitous assumptions about players decision criteria or beliefs the following discussion of these points is extremely brief due to space constraints more detailed arguments may be found in pearce 18

oil prices exchange rates and emerging stock markets abstract while two different streams of literature exist investigating 1 the relationship between oil prices and emerging market stock prices and 2 the relationship between oil prices and exchange rates relatively little is known about the dynamic relationship between oil prices exchange rates and emerging market stock prices this paper proposes and estimates a structural vector autoregression model to investigate the dynamic relationship between these variables impulse responses are calculated in two ways standard and the recently developed projection based methods the model supports stylized facts in particular positive shocks to oil prices tend to depress emerging market stock prices and us dollar exchange rates in the short run the model also captures stylized facts regarding movements in oil prices a positive oil production shock lowers oil prices while a positive shock to real economic activity increases oil prices there is also evidence that increases in emerging market stock prices increase oil prices

redefining business success distinguishing between closure and failure new firms are believed to have high closure rates and these closures are believed to be failures but two u s census bureau data sources illustrate that these assumptions may not be justified the business information tracking series bits showed that about half of new employer firms survive beyond four years and the characteristics of business owners cbo showed that about a third of closed businesses were successful at closure the cbo also made it possible to compare results of models of business survival and business success but because of non response bias logit models were used similar to previous studies firms having more resources that were larger with better financing and having employees were found to have better chances of survival factors that were characteristic of closure such as having no start up capital and having a relatively young owner were also common in businesses considered successful at closure hence few defining factors can be isolated leading to true failures the significant proportion of businesses that closed while successful calls into question the use of business closure as a meaningful measure of business outcome it appears that many owners may have executed a planned exit strategy closed a business without excess debt sold a viable business or retired from the work force it is also worth noting that such inborn factors as race and gender played negligible roles in determining survivability and success at closure

failure or voluntary exit reassessing the female underperformance hypothesis abstract we reevaluate the female underperformance hypothesis by challenging the assumption that female owned ventures are more likely to fail instead of equating exit with failure we draw on exit literature and feminist theories to argue that female entrepreneurs are actually more likely than males to exit voluntarily we argue for further gender differences by using an even more fine grained conceptualization of entrepreneurial exit failure exit for personal reasons and exit for other professional financial opportunities post hoc analyses also point to within gender heterogeneity depending on family status a sample probe of 219 spanish entrepreneurs who had exited their business supports our overall reasoning

new directions in entrepreneurship research with the kauffman firm survey data is a fundamental impediment to a better understanding of the multifaceted process of new firm creation with better data we can form a better understanding of the causes constraints and outcomes associated with the decision to launch a new business towards this end the kauffman foundation commissioned an eight wave panel of businesses that were formed in 2004 chronicling a single cohort s evolution from birth through important business milestones this issue of small business economics focuses on papers that use the kauffman firm survey to examine new research questions in entrepreneurship articles in this issue analyze new research topics in entrepreneurship as well as shed light on enduring questions in the literature

the persistence and dynamics of new venture growth extensive research has suggested that new ventures growth rates lack persistence however existing studies tend not to differentiate between positive and negative growth rates or examine their respective persistence and dynamics building on performance feedback theory we show that positive and negative growth rates exhibit different dynamics over time especially negative growth rates are less likely to persist and more likely to reverse than positive ones furthermore firm size and team size influence the persistence or the lack of thereof of both positive and negative growth rates specifically new ventures that are smaller as well as those managed by larger teams are more likely to maintain positive growth and reverse negative growth relative to their respective counterparts overall this study suggests that positive and negative growth rates differ in their persistence and that new ventures can shape the dynamics of both positive and negative growth

strategic trading behavior and price distortion in a manipulated market anatomy of a squeeze abstract this paper investigates an attempted delivery squeeze in a bond futures contract traded in london using cash and futures trades of dealers and customers we analyze their strategic trading behavior price distortion and learning in a market manipulation setting we argue that marked differences in settlement failure penalties in the cash and futures markets create conditions that favor squeezes we recommend that regulators require special flagging of forward term repurchase agreements on the key deliverables that span futures contract maturity dates and that exchanges mark to market their contract specifications more frequently or consider a cash settled contract on a basket of bonds

futures trading and the welfare evaluation of commodity price stabilisation it is notorious that commodity prices are volatile and there is a substantial literature on the wisdom of complete or partial elimination of this volatility the modern academic literature starts from waugh i944 who argued that consumers benefit from price volatility since they can take advantage of low prices by increasing consumption and oi i96i who argued the parallel proposition for producers massell i969 noting that waugh had assumed supply side disturbances whilst oi had assumed demand side disturbances provided an integrated model in the same spirit samuelson i972 showed that notwithstanding the contributions of waugh and oi it will not be beneficial within a standard competitive market clearing model to destabilise prices the literature is surveyed in turnovsky i978 this raises the question of whether stabilisation can be justified in the context of a competitive free market in which private agents make optimal stockholding decisions wright and williams i982 a number of authors see for example johnson i967 ch 5 have suggested that the fundamental theorem of welfare economics rules out such intervention standard arguments that would qualify this conclusion are superior governmental access to capital markets or information and the assertion that stabilisation may result in a favourable redistribution of income newbery and stiglitz i98i have stressed the rather more powerful argument that application of the fundamental theorem of welfare economics in an uncertain and explicitly intertemporal context requires the existence of a complete set of forward and contingent contracts markets futures or forward markets do exist for delivery of many important primary commodities at near dates but this is far from sufficient to satisfy the prerequisites of the theorem since agents will use those markets which do exist as substitutes for those that are absent since for example moral hazard considerations prevent widespread trading of crop insurance contracts farmers are obliged to obtain insurance against poor crops through the imperfect substitute of hedging on futures markets the limited range of futures and contingent claims markets invalidates the argument that intervention can never be justified in welfare terms but at the same time this only establishes the possibility of a justification for intervention a specific case must be made for each market futures trading allows market transactors to fix their prices in advance of delivery for example a farmer may completely hedge by selling his entire

why do most firms die young a model is developed to explain why most firms die in the first few years of trading a risk averse entrepreneur with initial capital endowment faces a brownian motion in net worth over time to balance return profits growth and risk variance of profits she adopts a portfolio strategy choosing market positioning to achieve an optimal combination of risk and return at each instant given her financial and human capital endowments and attitude towards risk failure occurs when the firm s value falls below the opportunity cost of staying in business the resulting distribution of failure is inverse gaussian implying for specific parameter values a positively skewed failure curve of the type observed in practice in addition the model presents a novel measure of management human capital mhc which implies that high mhc entrepreneurs will have higher absolute and marginal profits growth than low mhc entrepreneurs at given levels of risk

measuring financial asset return and volatility spillovers with application to global equity markets we provide a simple and intuitive measure of interdependence of asset returns and or volatilities in particular we formulate and examine precise and separate measures of return spillovers and volatility spillovers our framework facilitates study of both non crisis and crisis episodes including trends and bursts in spillovers and both turn out to be empirically important in particular in an analysis of sixteen global equity markets from the early 1990s to the present we find striking evidence of divergent behavior in the dynamics of return spillovers vs volatility spillovers return spillovers display a gently increasing trend but no bursts whereas volatility spillovers display no trend but clear bursts

futures trading and volatility in the gnma market futures markets for agricultural commodities have existed for well over 100 years recently there has been a major expansion of futures trading into nontraditional areas particularly interest bearing securities and foreign currenciesthe so called financial futures the introduction of exchange traded futures contracts for treasury bills gnma pass through certificates and other securities has created new hedging arbitrage and speculative opportunities for the investors issuers and dealers who are active in the cash markets for these securities futures trading has also opened these markets to participation by new classes of traders particularly private and smaller institutional investors through the process of arbitrage a financial futures market will be closely linked to the cash market for the underlying securities an important concern of the regulatory authorities is what effect opening a futures market is likely to have on an existing cash market the purpose of this paper is to analyze the impact of futures trading in government national mortgage association gnma passthrough certificates on price volatility in the cash market for these securities there are several major ways in which opening futures trading can increase efficiency and smooth price variations in a cash market most importantly futures provide a mechanism for those who buy and sell the actual security or commodity to hedge themselves against unfavorable price changes through the futures market risk can be spread across a large number of investors and transferred away from those hedging spot positions to professional speculators who are more willing and able to bear it this risk transfer may substantially improve the functioning of the spot market because it reduces the need to incorporate risk premia in cash market transactions to compensate for the risk of price fluctuations second futures market may increase the informational efficiency of a cash market since futures prices are determined in a unified highly visible market by traders who specialize in gathering and evaluating information the futures market is expected to be an efficient market in the sense that prices will reflect the best estimate of true future values given the information currently available if anything an informationally efficient futures market should lead to more efficient pricing in the cash market the importance of both of these effects will depend upon the structure of the existing cash market the more developed and integrated is the cash market the

dynamic spillovers between oil and stock markets in the gulf cooperation council countries this article exploits a new spillover directional measure proposed by diebold and yilmaz 2009 2012 to investigate the dynamic spillover of return and volatility between oil and equities in the gulf cooperation council countries during the period 2004 to 2012 our results indicate that return and volatility transmissions are bi directional albeit asymmetric in particular the oil market gives other markets more than it receives in terms of both returns and volatilities these trends were more pronounced in the aftermath of the global financial crisis in 2008 as the net contribution of oil has intensified after a burst during the crisis the empirical evidence from the sample is consistent with a system in which oil is playing the dominant role in the information transmission mechanism between oil and equities in the gcc countries

crude oil and stock markets stability instability and bubbles abstract we analyze the long run relationship between the world price of crude oil and international stock markets over 1971 1 2008 3 using a cointegrated vector error correction model with additional regressors allowing for endogenously identified breaks in the cointegrating and error correction matrices we find evidence for breaks after 1980 5 1988 1 and 1999 9 there is a clear long run relationship between these series for six oecd countries for 1971 1 1980 5 and 1988 2 1999 9 suggesting that stock market indices respond negatively to increases in the oil price in the long run during 1980 6 1988 1 we find relationships that are not statistically significantly different from either zero or from the relationships of the previous period the expected negative long run relationship appears to disintegrate after 1999 9 this finding supports a conjecture of change in the relationship between real oil price and real stock prices in the last decade compared to earlier years which may suggest the presence of several stock market bubbles and or oil price bubbles since the turn of the century

market and survey forecasts of the three month treasury bill rate in this article four readily available one quarter ahead forecasts of the three month u s treasury bill rate are compared the forecasts considered are 1 a prediction from the futures market 2 a forecast derived from an implicit forward rate calculation 3 a survey gathered forecast and 4 a no change forecast each forecast is examined for general forecast accuracy and for the extent of bias contained in each forecast over the twelve year period 1977 88 results indicate that the futures rate statistically dominates the other three forecasts while the survey and forward rate projections generally are found to be the least accurate and most biased copyright 1992 by university of chicago press

the decline in idiosyncratic values of us treasury securities abstract unique features and market frictions can lead to idiosyncratic pricing for some us treasury securities this study uses a linear programming lp model to measure aggregate idiosyncratic pricing of t notes and t bonds from 1980 to 2016 we document an average idiosyncratic pricing of 0 11 per 100 par as compared to an average bid ask spread of 0 08 further idiosyncratic pricing declined dramatically from the early 1980s to the 2010s empirical evidence suggests that the 1986 tax reform act increasing issue sizes and improving market liquidity contribute to the decline at the individual security level we identify factors contributing to and mitigating idiosyncratic pricing

futures trading activity and stock price volatility we examine whether greater futures trading activity volume and open interest is associated with greater equity volatility we partition each trading activity series into expected and unexpected components and document that while equity volatility covaries positively with unexpected futures trading volume it is negatively related to forecastable futures trading activity further though futures trading activity is systematically related to the futures contract life cycle we find no evidence of a relation between the futures life cycle and spot equity volatility these findings are consistent with theories predicting that active futures markets enhance the liquidity and depth of the equity markets

the impact of stock index futures trading on daily returns seasonality a multicountry study in this article we investigate the impact of the introduction of stock index futures trading on the daily returns seasonality of the underlying index for seven national markets it has been previously argued that the introduction of futures trading should lead to reduced seasonality of mean returns and generally our results support this conclusion the impact of index futures introduction on return autocorrelations and volatility is also tested and the evidence presented suggests that futures trading has no impact on the former although a change in the seasonal for the latter was detected

meteor showers or heat waves heteroskedastic intra daily volatility in the foreign exchange market this paper seeks to explain the causes of volatility clustering in exchange rates careful examination of intra daily exchange rates provides a test of two hypotheses heat waves and meteor showers the heat wave hypothesis is that the volatility has only country specific autocorrelation alternatively the meteor shower is a phenomenon of intra daily volatility spillovers from one market to the next using the garch model to specify the heteroskedasticity across intra daily market segments we find that the empirical evidence is generally against the null hypothesis of the heat wave using a volatility type of vector autoregression we examine the impact of news in one market on the time path of per hour volatility in other markets

initial human and financial capital as predictors of new venture performance abstract this research seeks to predict the performance of new ventures based on factors that can be observed at the time of start up indicators of initial human and financial capital are considered to determine how they bear upon the probability of three possible performance outcomes 1 failure 2 marginal survival or 3 high growth four categories of initial human and financial capital are examined general human capital represented here by the entrepreneur s education gender and race may reflect the extent to which the entrepreneur has had the opportunity to develop relevant skills and contacts management know how embodied in the entrepreneur or available through advisors or partners reflects management specific skills and knowledge without regard to the kind of business industry specific know how reflects specific experience in similar businesses financial capital is one of the most visible resources it can create a buffer against random shocks and allow the pursuit of more capital intensive strategies which are better protected from imitation the study utilizes a longitudinal study of 1053 new ventures representative of all industry sectors and geographical regions the research departs from most previous studies in considering different measures of performance marginal survival and growth and in considering explicitly whether the factors contributing to marginal survival differ from those contributing to high growth it was found that measures of general human capital influenced both survival and growth except for gender with women owned ventures being less likely to grow but just as likely to survive management know how variables had more limited impact having parents who had owned a business contributed to marginal survival but not to growth number of partners contributed to growth but not to survival management level prior employment in non profit organizations or not having been in the labor force and the use of professional advisors did not have significant effects industry specific know how contributed to both survival and growth amount of initial financial capital also contributed to both the usefulness of the model is enhanced by the fact that the resource variables considered are relatively easy to assess and all can be considered at the time of start up although some of the human capital variables cannot easily be changed the benefits or risks associated with each can be assessed in some cases potential problems can be identified so that plans can be modified to improve prospects overall it appears that using a model based upon the initial human and financial capital of the venture it is possible to predict the performance of new ventures with some degree of confidence

de stabilizing speculation on futures markets an alternative view point abstract this paper offers a new interpretation for possible destabilizing effects of opening futures markets in our model adapted from stein 1987 speculation on futures markets reduces the likelihood of occurrence of a rational expectations equilibrium although the equilibrium price is less volatile after the futures market is opened which is usually viewed as a stabilizing effect traders may find it more difficult or even impossible to coordinate their expectations in order to implement this equilibrium

risky business the survival implications of exploiting commercial opportunities by nonprofits prior research is equivocal as to the performance implications of exploiting market based opportunities by nonprofit organizations we investigate an under addressed measure of performance in this literature organizational survival drawing upon resource dependence theory we argue that performance is largely dependent upon the extent to which nonprofits focus on market based opportunities through analysis of the population of canadian charities we find support for a u shaped relationship indicating that low to moderate levels of market based income decrease the likelihood of firm exit whereas high levels increase this likelihood

the impact of financial futures on the cash market for treasury bills this paper is concerned with the effect of futures trading in treasury bills on the volatility of yields in the cash market it is found that futures trading led to a decrease in volatility initially but the effect disappeared when futures volume became large and possibly resulted in increased volatility in the secondary cash market the results also indicated that the deliverable bill appears to sell at a small premium relative to the adjacent maturities prior to the delivery date

what determines success examining the human financial and social capital of jamaican microentrepreneurs abstract this research examines the performance of 215 informal microenterprises in jamaica studying the influence of human capital social capital and financial capital of the owners on their business profitability understanding the importance of particular relationships that result in successful micro businesses is important for a number of reasons first among many developing countries the growth of microenterprise provides the most visibly vibrant and growing economic activity although considerable effort and resources are being directed toward microenterprise promotion schemes empirical research on the subject is quite limited second economies in developing countries mirror many of the social and institutional problems existent in urban economically disadvantaged areas of the united states and other developed countries for these areas microenterprise may be an essential component of urban renewal and community development this study helps in identifying important characteristics of social and individual attributes that may be relevant to those attempting to strengthen this subsector finally this study seeks to provide insight into a dimension of microbusiness research for which there are limited data specifically the role that social capital plays among practicing entrepreneurs and owners this research found that different structural environments even within a singular and small economy may considerably alter the rates of return to human social and financial capital as a result the analysis of enterprises includes segmentation according to both the usage or not of employees and the sophistication of the technologies used several factors were determined to enhance the profitability of the businesses in all categories vocational training for example demonstrated consistently strong and positive effects mother s high occupational status a proxy for socioeconomic status and years of experience in the business were also consistently positive and strongly associated with increasing profits although additional starting capital played an important role for both the businesses with and without employees increasing amounts failed to differentiate the success of those firms that were already operating in the higher technological tier obtaining a small business loan acted in a similar manner enhancing the profitability of all firms except those segmented into a high technological tier one interpretation of this finding is that the role of technological choice is extremely important and appears to dwarf that of varying amounts of starting capital social capital as operationalized by frequent church attendance and marital status of the owner was found generally to increase the profitability of the business the data demonstrate that social networks play an important role in the success of these businesses and that conditions in the highest tier utilize social capital in a somewhat unique manner

when do futures markets destabilise spot prices futures markets allow agents to shift price risk onto speculators and encourages them to take riskier decisions historically their main impact has been to encourage the storage of commodities thus arbitraging prices over time and reducing price fluctuations this paper presents a simple model in which opening futures markets in a nonstorable commodity encourages producers to choose riskier production techniques which destabilizes supply and hence the spot price copyright 1987 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

volatility volume co movements evidence from china metal markets abstractthis article investigates the interactional relationship between price volatility and futures trading activity for three heavily traded metal products on the shanghai metal exchange and the shanghai futures exchange using models based on vector autoregression and generalized method of moments we show in particular that futures trading activity has a strong impact on both spot and futures price volatility in copper and aluminium markets futures trading activity leads spot market volatility in copper and aluminium markets which suggests that futures markets have a destabilizing effect in order to disentangle the effect of different traders types on asset price movements we decompose futures trading into speculators and hedgers trading and investigate their contributions to volatility as a robustness check we investigate the impact of endogenous structural breaks on the interactional relationship between price volatility and futures trading

real effects of futures speculation asymptotically rational expectations to what extent does the diversity in the forecasting ability of futures speculators simply result in transfers of wealth among themselves and to what extent does it affect the allocation of resources on the basis of bayesian analysis it is assumed that the variance of forecast errors between the subjective and objective expectations of the subsequent price differs among groups two major conclusions are as follows 1 if given our parameter estimates the forecast error variance of the amateur speculators is less than six times that of the professionals then the existence of futures markets will lower the expected price to consumers increase expected output and lower the variance of the price 2 since small speculators lose to the professionals the relative variance of the forecast error of the amateurs to the professionals exceeds their relative weights as measured by the ratio of numbers to average risk aversion

small business failure and external risk factors unlike much of the previous literature which has generally focused on internal risk factors this study seeks to explore the impact of macro economic factors on small business mortality the results suggest that economic factors appear to be associated with between 30 and 50 of small business failures depending on the definition of failure used as expected failure rates were positively associated with interest rates where failure was defined as bankruptcy and the rate of unemployment where failure was defined as discontinuance of ownership however somewhat unexpectedly failure rates were found to be positively associated with lagged employment rates where failure was defined as to prevent further losses and with current and lagged retail sales where failure was defined as either failed to make a go of it discontinuance of ownership or discontinuance of business this indicates that a strengthening economy may provide the trigger for an increase in voluntary business exits as individual proprietors seek to maximize the returns available to them on both their financial and human capital
