We propose a reliability growth model that incorporates data from multiple stages of testing and acknowledges fixes implemented at the end of each stage. Competitive pressure and governmental regulations compress the time that can be devoted to product development. Limitations on budgets for...

Screening experiments are performed to eliminate unimportant factors efficiently so that the remaining important factors can be studied more thoroughly in later experiments. This paper proposes controlled sequential factorial design (CSFD) for discrete-event simulation experiments. It combines a...

Using a sample of listed Chinese firms between 2000 and 2010, the paper analyzes the stock market reaction to CEO succession. We document significantly positive cumulative abnormal returns when CEO succession is accompanied with increased political connections. We also show that the market...

Many outpatient clinics are experimenting with open access scheduling. Under open access, patients see their physicians within a day or two of making their appointment request, and long term patient booking is very limited.

Previous studies document that the stock returns of bond-issuing firms significantly underperform matched peers over the three to five years following issuance. We revisit this phenomenon and show that the underperformance is the result of an omitted return factor (a "bad model problem"). Debt...

Earlier studies have documented that three types of autocorrelations exist in financial time series: sign, volatility, and return autocorrelation. In this paper, we examine how each type of the above autocorrelations affects the statistical properties of financial time series and its role in...
