Automated Certification for Compliant Cloud-based Business Processes

A key problem in the deployment of large-scale, reliable cloud computing concerns the difficulty to certify the compliance of business processes operating in the cloud. Standard audit procedures such as SAS-70 and SAS-117 are hard to conduct for cloud-based processes. The paper proposes a novel approach to certify the compliance of business processes with regulatory requirements. The approach translates process models into their corresponding Petri net representations and checks them against requirements also expressed in this formalism. Being based on Petri nets, the approach provides well-founded evidence on adherence and, in case of noncompliance, indicates the possible vulnerabilities.     

The business plan as a project: an evaluation of its predictive capability for business success

Although there is extensive research aimed at identifying the main success factors for new ventures, efforts directed at evaluating the real effect of the existence and quality of a business plan on a firm's survival chances have been limited. This study attempts to fill this gap by analyzing to what extent the quality of a business plan, measured according to its economic, financial and organizational viability, constitutes a good predictor of business survival; and how other variables related to the characteristics of the entrepreneur and the business can affect the predictive capability of the model under consideration. Hypotheses are tested using data collected from 2142 service firms. The results show that none of the three variables that evaluate business plan quality (economic, financial and organizational viability) seems to have a determining influence on survival chances. Adding essential characteristics related to the entrepreneur and the business (education and training, experience, kind of motivation, number of employees and start-up capital) does little to increase the model's predictive capabilities.     

The consequences of labor market flexibility: Panel evidence based on survey data

We introduce a new data set on hiring and firing restrictions for 21 OECD countries for the period 1984-1990. The data are based on surveys of business people in the countries covered, so the indices we use are subjective in nature. Controlling for country and time fixed effects, and using dynamic panel data techniques, we find evidence that increasing the flexibility of the labor market increases both the employment rate and the rate of participation in the labor force. A conservative estimate suggests that if France were to make its labor markets as flexible as those in the US, its employment rate would increase 1.6 percentage points, or 14% of the employment gap between the two countries. The estimated effects are larger in the female than in the male labor market, although both groups seem to have similar long-run coefficients. There is also some evidence that more flexibility leads to lower unemployment rates and to lower rates of long-term unemployment. We also find evidence consistent with the hypothesis that inflexible labor markets produce “jobless recoveries” and introduce more unemployment persistence.     

The law and economics of self-dealing

We present a new measure of legal protection of minority shareholders against expropriation by corporate insiders: the anti-self-dealing index. Assembled with the help of Lex Mundi law firms, the index is calculated for 72 countries based on legal rules prevailing in 2003, and focuses on private enforcement mechanisms, such as disclosure, approval, and litigation, that govern a specific self-dealing transaction. This theoretically grounded index predicts a variety of stock market outcomes, and generally works better than the previously introduced index of anti-director rights.
