This study develops and operationalizes a behavioral forward-looking search model by incorporating prospect theory, organizational risk literature, and the logic of the behavioral theory of the firm. With recognition of the bounded rationality of decision makers and the goal-directed, rule-based nature of organizations, this model suggests that a comparison between firms' performance expectation and performance target translates the cognitive representation of the firms' future into their subsequent actions. By examining the research and development (R&D) expenditures of U.S. manufacturing firms from 1980 to 2001, this study explores how performance, aspirations, expectations, and slack affect decision making about firms' R&D search investments. The findings show that both performance feedback and performance prospect are important determinants of firms' search behavior after controlling for firm, industry, and time effects. In addition, backward- and forward-looking determinants have interactive effects on search behavior. Firms' problem-driven search activity further increases when firms feel unlikely to achieve the performance target for another year. In contrast, search intensity is reduced when firms expect to improve their performance from an underperforming situation to an outperforming situation. The findings suggest that future research on performance feedback and experiential learning should also consider the effect of forward-looking prospects on firm behavior.

This paper investigates the effects of organizational form on problemistic search. We contrast how Indian firms affiliated with business groups and unaffiliated firms evaluate performance and react by adjusting their internal technology search and external market search. We propose that, compared with unaffiliated firms, business group–affiliated (BG-affiliated) firms are more externally oriented in setting aspiration levels and more likely to respond to low performance in the market domain. We find support for an external orientation of BG-affiliated firms and find that group affiliation determines the responsiveness to performance feedback in different search domains. The findings suggest a need to add considerations of organizational form and governance to the theory of organizational search.

We investigate the effect of changes in a firm's knowledge couplings on its innovation performance. We develop arguments to explain how changes in couplings among existing knowledge domains and those between new and existing knowledge domains affect the generation of valuable inventions. We also examine how observed domain complexity, an indicator of the inherent interdependencies among knowledge domains, moderates the effects of changes in a firm's knowledge couplings on innovation performance. Our results suggest that a change in couplings among existing knowledge domains hurts innovation outcomes, but not when the degree of domain complexity is high, whereas coupling new and existing knowledge domains leads to improved outcomes, but not when the degree of domain complexity is high.

Cu(In,Ga,Al)Se 2 (CIGAS) thin films were investigated as an alternative absorber layer to Cu(In,Ga)Se 2 (CIGS). CIGAS thin films were prepared by pulsed laser deposition on SiO 2 /Si(100) and glass substrates at 150°C with different Al contents. The compositions of all films were measured by electron probe micro-analyzer. X-ray diffraction studies indicate that all the films are oriented along the [112] direction and that the (112) peak shifts to higher 2h value with increasing Al content. Scanning electron microscopy images show that dense and well-defined grains are formed as Al is incorporated into CIGS. Atomic force microscopy images indicate that the grain sizes and the roughness of the thin films decrease with increasing Al content. The bandgap of CIGAS thin films was determined from the optical spectra and was found to increase with increasing Al content.
