The current study reports changes in glucosinolate content in rapeseed mustard at different floral developmental stages. Variation in glucosinolate content seems to be primarily under control of reproductive developmental stages, which contribute to 47.18- 69.98% of total variance. Significant differences were found in glucosinolate content among 10 different genotypes of rapeseed mustard. Glucosinolate content was higher in protected than unprotected environment. Although significant stage x environment and stage x genotype effect was observed, these effects were small as compared influence due developmental stage and genotypes. Total glucosinolate content increases from flower initiation stage (FIS) to full bloom stage (FBS) while at pod maturity stage (PMS), it tends to decrease.

This paper uses a novel identification strategy proposed by Lewbel (2012, J. Bus. Econ. Stat.) to illustrate how causation between job satisfaction and life satisfaction can be established with cross-sectional data. In addition to examining the relationship between composite job satisfaction and life satisfaction, we consider the relationship between life satisfaction and different facets of job satisfaction. We find evidence of bidirectional causality between job satisfaction and life satisfaction and mixed evidence of causation between life satisfaction and different facets of job satisfaction.

Purpose – The purpose of the study is to examine the extent to which workplace policies and practices are related to participation in, and frequency and duration of, workplace training, controlling for worker and workplace characteristics. Design/methodology/approach - We regress variables depicting participation, frequency and duration of workplace training on workplace policies and control variables. In the case of participation in training, the dependent variable is binary; hence, we use a logit model. To examine the number of times which employees participate in training and the number of days they spend training we use a Tobit model. The Lewbel (2012) method is used to examine whether there is a causal relationship between workplace policies and the frequency, and duration, of training. Findings – The findings suggest that about half of the workplace policies considered are positively correlated with the incidence and breadth of workplace training. There is also some support fo...

We apply a recently developed unit root test that simultaneously accounts for heteroskedasticity and structural breaks to United States monthly natural gas consumption. We find that United States monthly natural gas consumption is stationary. Our results illustrate the importance of accounting for heteroskedasticity when testing for a unit root in energy consumption with higher frequency data.

This paper analyses how influence activities in the form of signal jamming affect the capital budgeting process of corporate organisations in Australia. Empirical results suggest that investment sensitivity (the relationship between investment in the smallest segment and its past performances) is positive for Australian firms. However, when influence problems within a firm become more severe, mixed evidence is obtained for different measures of influence activity. With an increase in the number of segments, influence activity becomes more severe and headquarters relies more on a public signal. In contrast, with the increase in relatedness across segments, the influence problem increases and headquarters relies more on private information from the manager of the large segment. Evidence suggests that Australian firms provide high short‐term incentive payments to managers of large segments to mitigate the influence activity problems, and thus rely more on managerial recommendations for...

We examine the relationship between gender of the barrister and appeal outcomes on the High Court of Australia. We find that an appellant represented in oral argument by a female barrister, opposed to a respondent represented in oral argument by a male barrister, is less likely to receive a High Court justice's vote. However, we also find that the appellant disadvantage of having a female barrister present oral argument is (partially) offset in the case of liberal justices and on panels having a higher proportion of female justices. The extent to which the disadvantage is offset, and potentially turns from being a disadvantage to an advantage, depends on the degree to which the justice is liberal and the proportion of female justices on the panel.

There is a large literature using unit root tests to test for weak form market efficiency in financial markets. Much of this literature takes account of the low power to reject the unit root null in the presence of structural breaks. However, the literature largely ignores the low power to reject the unit root null in the presence of heteroskedasticity. Heteroskedasticity is particularly problematic in high frequency financial data. We extend the literature by applying a unit root test which accommodates both heteroskedasticity and structural breaks to hourly data for five ASEAN stock indices. Our results point to the importance of allowing for heteroskedasticity when testing for a random walk in high frequency financial data.

A common problem when estimating the returns to schooling is the lack of conventional instrumental variables (IV) for education altogether or, if conventional IVs exist, there is often doubt as to whether they satisfy the exclusion restriction. We illustrate how a novel identification strategy, proposed by Lewbel (2012), which utilizes a heteroscedastic covariance restriction to construct an internal IV, can be used to obtain IV estimates for returns to education when alternatively there are no conventional IVs available or the conventional IVs that are available are potentially weak. To do so, we estimate the returns to schooling in urban China using two datasets. One dataset, which is for Shanghai, does not have any conventional IVs for education. The other dataset, which is for urban residents from across China, contains information on conventional IVs (parents’ education). We find that, in the case of returns to schooling, the Lewbel method provides plausible estimates in datase...

This study compares the research productivity and impact of inbred and non-inbred faculty employed at Australian law schools. The sample consists of 429 academics, employed at 21 law schools. To measure research productivity and impact we use articles published in top law journals, defined in six different ways, as well as total citations and two different citation indices. We report results including, and excluding, publications in the academic’s home law review. We find evidence that silver-corded faculty outperform other faculty on one of the measures of publications in top journals, once the endogeneity of academic seniority, grant history and the status of the law school at which the individual is employed is addressed, but this finding is not robust across alternative measures of articles published in the top journals. We find that there is no statistically significant difference between the research productivity and impact of inbred and non-inbred faculty. This finding is rob...

Purpose ‐ The purpose of this paper is to use cross-sectional data collected from six cities in China to examine the relationship between subjective wellbeing and male and female earnings and also to consider the contribution of differences in subjective wellbeing to explaining the gender wage gap. Design/methodology/approach ‐ The paper uses survey data for 3,390 respondents working in a variety of blue collar and white collar jobs across a range of sectors including government, heavy and light manufacturing, mining and services in six Chinese cities: Chengdu, Dalian, Fushun, Fuxin, Fuzhou and Wuhan. The authors employ the ordinary least squares, Lewbel instrumental variable and Blinder-Oaxaca decomposition to econometrically analyze the relationship between subjective wellbeing and gender wage gap. Findings ‐ The paper finds that the relationship between subjective wellbeing and wages is stronger for males than females. The authors note that 0.2 percent of the observed gender wage...

We test for convergence in energy consumption per capita among ASEAN countries over the period 1971 to 2011 using the panel KPSS stationarity test and panel Lagrange multiplier (LM) unit root test. The results for the panel stationarity and unit root tests with structural breaks find support for energy convergence in ASEAN.

Cognitively appraised life satisfaction is relatively stable over time and can be considered as reflecting subjective wellbeing in the long run. Affect is transitory and can be considered as reflecting subjective wellbeing in the short run. Using the Personal Wellbeing Index to measure cognitively appraised life satisfaction and the Positive and Negative Affect Schedule to measure positive and negative affect we examine how income relative to one’s comparator group and variations in short run wellbeing impact upon wellbeing in the long run. We do so for China’s Korean ethnic minority. We find that affective state has an effect on wellbeing in the long run and that a negative shock to affectivity is more persistent than a positive shock. We also find that relative income, rather than absolute income, matters for wellbeing in the long run and that the results are consistent with a status effect.

This paper is an empirical study of the intraday liquidity patterns on the National Stock Exchange (NSE) of India. Using trade and quotes data on stocks contained in the NIFTY index, we find that most of the volume and spread related to liquidity measures are U-shaped, similar to those found in a quote driven market. Such patterns also indicate a contradictory feature of concurrent high trading volume and wide spreads, a feature that is new to an order driven market such as the NSE. Additionally, this paper also measures marketwise liquidity by checking for commonality among liquidity measures. Empirical results show that there is only weak evidence of commonality, suggesting sensitivity to commonality need not be a priced risk.

This study examines the relationship between academic seniority and research productivity through a study of a sample of academics at Australian law schools. To measure research productivity, we use both publications in top law journals, variously defined, and citation metrics. A feature of the study is that we pay particular attention to addressing the endogeneity of academic rank. To do so, we use a novel identification strategy, proposed by Lewbel (Journal of Business and Economic Statistics 30:67–80, 2012), which utilises a heteroscedastic covariance restriction to construct an internal instrumental variable. Our main finding is that once endogeneity of academic rank is addressed, more senior academics at Australian law schools do not publish more articles in top law journals (irrespective of how top law journals are defined) than their less senior colleagues. However, Professors continue to have greater impact than Lecturers when research productivity is measured in terms of to...
