Risk tolerance,gender, and entrepreneurship: The Palestinian case

This paper analyzes the inter‐relationships between entrepreneurial propensity, fear of failure (FoF), and gender in Palestine, using the Global Entrepreneurship Monitor (GEM) adult population survey (APS) data for 2009, 2010, and 2012, and it is the first that addresses Gender, fear of failure, and entrepreneurship for Palestine. The paper extends the analysis of the endogeneity issue of FoF by using the conditional mixed process (CMP), which improves the efficiency of the estimates. The results show that the fear of failure negatively affects entrepreneurial status, while skill perception does the opposite. It is also found that fear of failure is higher among women, although this result is not stable over time. Using the CMP specification, we find that gender and fear of failure both reduce the predicted probability of entrepreneurship consistently over time. The only variable that consistently predicts fear of failure and is significant is skill perception, which has a negative impact. Policy implications of this research point to the importance of reducing the gender gap in entrepreneurship. In particular, there is a need to improve their skill perception in order to encourage more females to be entrepreneurs. Networking, vocational education and media coverage of success stories are among the tools that could potentially achieve this result.     

Testing the effects of self-regulation on industrial accidents

Our study, the first to test the impact of self-regulation on industrial accidents, examines Responsible Care (RC) in the US chemical manufacturing sector. RC requires members to adhere to codes of conduct on production safety and pollution prevention. Using our author-constructed database of 1,867 firms that own 2,963 plants between 1988 and 2001, we instrument for firms’ self-selection into RC using pollution-related regulatory pressure on firms that influences their probability of joining RC, but not plant-level accidents. We find that participation in RC reduces the likelihood of accidents by 2.99 accidents per 100 plants in a given year, or by 69.3%. Participation in RC also reduces the likelihood of process safety accidents and accidents related to violations of RC codes by 5.75 accidents per 100 plants in a given year, or by 85.9%. Alternatively, estimates using Propensity Score Matching (PSM) methods indicate that participation in RC reduces the likelihood of accidents by 0.66 accidents per 100 plants in a given year. The reduction in the likelihood of accidents, due to participation in RC, contributes to economically significant averted losses, with savings, even based on the smaller PSM estimates, totaling $180 million per year.     

The impact of piped water provision on infant mortality in Brazil: A quantile panel data approach

We examine the impact of piped water on the under-1 infant mortality rate (IMR) in Brazil using a recently developed econometric procedure for the estimation of quantile treatment effects with panel data. The provision of piped water in Brazil is highly correlated with other observable and unobservable determinants of IMR — the latter leading to an important source of bias. Instruments for piped water provision are not readily available, and fixed effects to control for time-invariant correlated unobservables are invalid in the simple quantile regression framework. Using the quantile panel data procedure in Chen and Khan [Chen, S., Khan, S., Semiparametric estimation of non-stationary censored panel model data models with time-varying factor. Econometric Theory 2007; forthcoming], our estimates indicate that the provision of piped water reduces infant mortality by significantly more at the higher conditional quantiles of the IMR distribution than at the lower conditional quantiles (except for cases of extreme underdevelopment). These results imply that targeting piped water intervention toward areas in the upper quantiles of the conditional IMR distribution, when accompanied by other basic public health inputs, can achieve significantly greater reductions in infant mortality.     

On selecting the best ofk lognormal distributions

Summary Fork lognormal populations, which differ only in one certain parameter Ϙ, the problem of finding the population with the largest value ofϑ is considered. For two-parameter lognormal families, several natural choices ofϑ are treated, where the problem can be solved, through logarithmic transformation of the observations, within the framework of estimating parameters ink, possibly restricted, normal populations. For three-parameter lognormal families, this standard approach of selecting in terms of natural estimators fails to work ifϑ is the “guaranteed lifetime”. For this case, a selection procedure is derived which is based on anL-statistic which has the smallest asymptotic variance. Of importance here is that it is location equivariant, whereas it does not matter what it actually estimates. Comparisons are made with other suitable selection rules, through the asymptotic relative efficiencies, as well as in an example of intermediate sample sizes. It is shown that only in the latter, the selection rule, which is based on the sample minima, compares favorably.

Are there arbitrage gaps in the UK gilt strips market?

Evidence in financial markets of an opportunity for pure arbitrage, and therefore a violation of the law of one price, is considered an anomaly to be noted. This paper reports an apparent violation of the law of one price between UK government gilts and their separately traded principal and coupon strips over a sample period of nearly 14 years. There are persistent price differences, and hence opportunities for arbitrage, after allowance for the bid-ask spread; the strips package tends to be overpriced in relation to the corresponding gilt. The price differences may, in part, be due to a lack of liquidity and stale prices in the strips market.     

Small and Medium‐Sized Enterprise's Entrepreneurial versus Market Orientation and the Creation of Tacit Knowledge

The ability to create tacit knowledge is important to the competitive advantage of firms in general but is critical to the survival and growth of small and medium‐sized enterprises (SMEs). Consequently, SME strategic orientations that facilitate tacit knowledge creation, especially in hostile environments, are important factors that can enhance SME competitiveness. This paper shows that while an entrepreneurial orientation (EO) and environmental hostility are positively related to an SME's cultivation of tacit knowledge, market orientation (MO) is negatively related to SME's tacit knowledge. Additionally, we find that in benign environments, the relationship between an SME's MO and tacit knowledge becomes more strongly negative than in hostile environments.     

Does industry self-regulation reduce pollution? Responsible Care in the chemical industry

Self-regulation programs, in which industry associations set membership codes beyond government regulations, are prevalent despite scarce evidence on their effectiveness. We examine Responsible Care (RC) in the US chemical manufacturing sub-sector, whose membership codes include pollution prevention, using our author-constructed panel database of 3,278 plants owned by 1,759 firms between 1988 and 2001. We apply two sets of instrumental variables to address a plant’s parent firm’s self-selection into the program, using: (i) the characteristics of other plants belonging to the same firm in our multi-plant sample; and (ii) firm participation in the industry association before the establishment of RC and industry-level RC participation in our full sample. We find that on average, plants owned by RC participating firms raise their toxicity-weighted pollution by 15.9% relative to statistically-equivalent plants owned by non-RC participating firms. This estimated increase is large relative to the yearly 4% reduction in pollution among all plants in our sample between 1988 and 2001. Moreover, RC raises plant-level pollution intensity by 15.1%. These results caution against reliance on self-regulation programs modeled on the pre-2002 RC program that did not require third party certification and in those sectors that lack independent third party certification.
