Exploring risk dimensions in the Indian software industry

The success of software projects is quite subjective in nature and is fettered by many risks, the perception of which varies from individual to individual and largely depends on the demographic characteristics of the executives and even the characteristics of the project. This study aims to identify and gauge the software risk dimensions and analyze the differences of perception among executives toward software risks. The contributions of this study untangle the issues underlying risks in the software industry and associates these issues with the perception of the “human” factor present in the industry.     

Risk in supply response: an econometric application

The impact of risk aversion on supply response is empirically estimated for selected field crops in California. As indicators of risk aversion the following surrogate variables are used: variance of past prices and yields, adjusted price to reflect the role of government support price over the market price and the dummy variables indicating price expectations. In general, the econometric estimates show a negative impact of risk aversion measured by the surrogate variables and this has implications for welfare gains resulting from price support policies aimed at stabilization.     

Admissible unbiased variance estimation in finite population sampling under randomized response

LetP be the proportion of units in a finite population possessing a sensitive attribute. We prove the admissibility of (i) an unbiased estimator of the variance of a general homogeneous linear unbiased estimator ofP and (ii) an unbiased estimator of the population varianceP(1−P), based on an arbitrary but fixed sampling design, under the randomized response plans due to Warner (1965) and Eriksson (1973). Admissibility of an unbiased strategy for estimating the population variance is also established.     

The impact of employee‐share‐ownership schemes on performance in unionised and non‐unionised workplaces

Conventional wisdom suggests that higher performance is observed when employee‐share‐ownership (ESO) schemes coexist with employee participation arrangements. However, the evidence is inconclusive and it has been suggested that performance benefits occur in ESO workplaces only when employees are actually involved in the decision‐making process. Drawing on the cross‐section data from the 1998 Workplace Employee Relations Survey, the article shows that higher productivity is observed in those workplaces where unions coexist with ESO schemes. This result highlights the relevance of unions to High Performance Work Systems.     

On interpenetrating samples of unequal sizes

Summary Koop [1967] proved that interpenetrating samples of unequal sizes are more efficient than those with equal sizes for estimating a finite population total. After observing that there is a serious lacuna present in his proof, a correct proof has been suggested. The optimum choice of individual sample sizes has also been discussed for a given (i) total sample size, (ii) cost and (iii) precision, with an assumed cost structure. Finally, the resulting estimators have been compared with those based on a single sample.     

Credit Scoring and Loan Default

A metric of credit score performance is developed to study the usage and performance of credit scoring in the loan origination process. We examine the performance of origination FICO scores as measures of ex ante borrower creditworthiness using loan‐level data on ex post performance of subprime mortgages. Parametric and nonparametric estimates of credit score performance reveal different trends, especially on originations with low credit scores. The data suggest a trend of increased emphasis on higher credit scores accompanying a trend of increased riskiness in other origination attributes. Over time, this increased emphasis on credit scoring coincided with deterioration in FICO performance largely because of the fact that higher credit score originations of later cohorts were more likely to have riskier attributes. However, controlling for other attributes on originations and changes in economic conditions, we find that, as measures of borrower ranking, FICO performance on subprime loans over the years remains fairly stable.     

Interest rate pass-through in India

The success of the interest rate channel depends upon the size and speed with which retail interest rates respond to changes in policy or money market interest rates. This study estimates the dynamic elasticities of the pass-through of the official monetary policy rate to the money market and retail interest rates in India and examines whether the speed and magnitudes of the pass-through have changed following introduction of the Liquidity Adjustment Facility in 2000. The results show that the speed of adjustment is highest for call rates and lowest for 364-day Treasury Bill yield. The pass-through elasticities with respect to call rate show marginal improvement in the case of deposit and lending rates and worsening in the case of Treasury Bills.
