Person–project fit and R&D performance: a case study of Industrial Technology Research Institute of Taiwan

This study examined the relation between the research and development (R&D) performance and the fit between a researcher's cognitive type and the task demand of the project that was implied in Wang, Wu & Horng's (1999) study. Three hundred and eighteen research projects completed by 205 project leaders in the 3 years were classified into Unsworth's four creativity types along two dimensions: (1) whether the research addressed an open- or closed-ended problem and (2) whether the project was assigned or actively sought by the researcher. Each researcher's personal traits were assessed using Myers–Briggs Type Indicator (MBTI) and Kirton's Adaptor–Innovator Scale (KAI). Results show that researchers with a conforming, feeling, or judging-type cognition performed better with assigned projects for solving closed problems. Those with an originality and intuitive-type cognition performed better on self-initiated projects for solving open-ended problems. Researchers with sensing-type cognition performed better with assigned projects for solving open-ended questions. Thus, a careful match between a researcher's cognitive type and the task demand of project is important for R&D management.

Beyond the purchasing power parity: testing for cointegration and causality between exchange rates, prices, and interest rates

This paper reexamines the causality between the dollar and the yen in a multivariate framework with the aid of cointegration and error-correcting modeling for the 1951–94 period. The Phillips-Perron tests and Johansen's tests are performed. While causality from interest rates to exchange rates is found in the short run, no causality between prices and exchange rates is found in the short run. However, causality is found running from relative prices to exchange rates along with interest rates between the U.S. and Japan in the long run, which supports the long-run PPP hypothesis.

Radical innovations in new product development and their financial performance implications: An event study of US manufacturing firms

At the dawn of the 21st century, global competition continues to increase at an accelerating rate and radical innovation is recognized as a potent weapon for firms to achieve sustainable competitive advantages. Academics, practitioners and consultants share the view that radical innovation is important to the long-term financial success of firms. Nevertheless, empirical studies on the relationship between radical innovation and firm performance have been dominated by survey research, which provided little concrete evidence on the financial impact of radical innovation. In this study we traced the financial performance of publicly traded manufacturing firms in the United States that introduced radical innovations over the period 1986-2000 and examined whether radical innovation could lead to superior financial performance in these firms. We employed the event-study method, matching each sample firm with a control group of firms in the same industry with similar pre-event performance and firm size. Our results show that while radical innovation helps firms maintain sales growth and return on sales (ROS), firm profitability in terms of return on assets (ROA) is not significantly improved. In fact, manufacturers suffer from a decline in profitability upon the introduction of radical innovations in new product development.

Intrinsic bubbles and Granger causality in the S&P 500: Evidence from long-term data

Results of research on whether changes in earnings can predict future stock returns are inconclusive. We add to this debate by using long-term data from 1871 to 2004 to examine the predictive power of changes in earnings in periods of intrinsic bubbles and in periods absent intrinsic bubbles. Our results show that accounting for bubbles is important in whether changes in earnings can predict future stock returns. In periods of no bubble, we find that changes in earnings Granger-cause future returns, whereas in periods of bubble, this Granger causality from changes in earnings to future returns cannot be found. We conclude that changes in earnings can predict future stock returns, but only in periods absent bubbles.
