Firms engaged in high-technology government and commercial contracts allocate discretionary funds to R&D projects to enhance the quality of prototype design. We propose a method for targeting enhancements which appeal to clients while also providing technological advantage vis-a-vis other firms competing for the same contracts. R&D projects can be scored on their contribution to contract selection criteria and compared in the context of a technology portfolio, a matrix that reveals the relative merits of the engineering proposals and potential technology niches.

Knowledge on clients, competitors and priorities regarding selection criteria is often judgmental and fragmented within the firm. Meaningful translation of various experts' comparisons into a hierarchical, internally consistent scoring scheme is achieved with Saaty's analytic hierarchy process. Carefully specified technical benchmarks, used to scale quality and cost data, are also instrumental for soliciting judgmental knowledge. Implementation of the technology portfolio assessment is illustrated with a practical example drawn from defense contracting.  相似文献

Not much is known about the returns to aging (maturing) in the market for small business finance. Using a large panel of closely held micro firms, we document that the cost of debt capital is higher for young firms. The main finding of this paper is that this negative qualitative relation is also obtained when cross‐sectional variation in unobservable creditworthiness of small businesses and within‐firm (i.e., inter‐temporal) variation in their observable creditworthiness are held constant. We control for the former by firm‐specific fixed effects and for the latter by a commercial credit score. We also provide an estimate of the quantitative magnitude of the aging effect, on which both economic theory and earlier empirical research are silent. We find that when a small business ages one year, its cost of debt capital decreases by 1–2 basis points. The effect is neither negligible nor alarmingly large.  相似文献

Existing firms are argued to be an important source of new entrepreneurs. Yet, relatively little is known about the characteristics of firms that breed new entrepreneurs. We use a large linked employee–employer dataset to trace and characterize the types of firms which generate new entrepreneurs in Finland. We find that such transitions are rare and that smaller firms spawn new entrepreneurs more frequently than larger firms. We also find that firms' R&D intensity and, to a lesser extent, their productivity are negatively related to the probability that employees transit into entrepreneurship. These results are robust to controlling for a number of employee and employer attributes.  相似文献

Trade regimes and spillover effects of FDI: Evidence from Uruguay   总被引:9,自引:0,他引:9  
Trade Regimes and Spillover Effects of FDI: Evidence from Uruguay. — This paper examines differences in the character and impact of FDI entering Uruguay during import substitution, pursued until 1973, and the subsequent more outwardoriented trade regime. Regression analysis shows that the labor productivity of local firms is positively related to the presence of older import-substituting MNCs in their industry. The presence of foreign affiliates established after 1973 has no apparent impact on local productivity, but seems to raise the likelihood that local firms engage in exporting. This may be a sign of export spillovers, indicating that local firms may pick up some exportrelated skills from the operations of outward-oriented foreign MNCs.  相似文献

There is a need of further research to understand how social capital in the organization can be fostered. Existing literature focuses on the design of reciprocity norms, procedures and stability employment practices as the main levers of social capital in the workplace. Complementary to these mechanisms, this paper explores the impact of ethical managerial behaviour on the development of social capital. We argue that a managerial behaviour based on the true concern for the well-being of employees, as well as their motivational and ethical development, can be particularly important for the generation of social capital in the organization. It is suggested that manager’s behaviour should be based on three principles: following exemplary behaviour, helping the employees to value the consequences of their actions in other persons, and not betraying employee’s trust. When the manager conforms to those principles, he can ease the process through which employees develop associability and identification-based trust with the firm, the two main components of ?Organizational Social Capital’. Bringing ethics into the debate of social capital creation seems to us fundamental, as social capital in the firm is likely to be influenced by the ethical and motivational development of its members.  相似文献

The empirical relationship between a firm’s social performance and its financial performance is still not well established in the literature. Despite more than 30 years of research and more than 100 empirical studies on the issue, the results are still mixed. We argue that the heterogeneous results found in previous studies are not due exclusively to problems related with the measurement instruments or the samples used. Instead, we posit that a more fundamental problem related with the endogeneity of social strategic decisions could be driving most of the empirical findings. We show that, using a panel data of 658 firms from 1991 to 2005, how some of the results found in previous research change, and some are even reversed when endogeneity is properly taken into account.  相似文献

In investigating the concept of diversification and its link to performance, strategy researchers have tended to emphasize economic, technological, or market characteristics that distinguish or relate one business to another. However, by ignoring the mental maps corporate-level managers use to understand and manage strategic variety among their firm's businesses, strategy research has failed to produce an overall theory that links diversification to performance. Although the literature has begun to reaffirm the importance of developing a cognitive concept of diversification, researchers have been frustrated by the paucity of methods that are suitable for operationalizing the subjective characteristics of managerial mental maps into quantitative and reproducible measures. In addressing this deficit, this article proposes the use of the Repertory Grid, a set of procedures that facilitates elicitation and quantification of top managers' mindsets towards the firm's mix of businesses. After outlining the theoretical and methodological foundations of the Repertory Grid, the paper defines indices of grid structure and content and demonstrates the utility of grid data for assessing diversification.  相似文献

While most economists agree that seigniorage is one way governments finance deficits, there is less agreement about the political, institutional and economic reasons for relying on it. This paper investigates the main political and institutional determinants of seigniorage using panel data on about 100 countries, for the period 1960–1999. Estimates show that greater political instability leads to higher seigniorage, especially in developing, less democratic and socially-polarized countries, with high inflation, low access to domestic and external debt financing and with higher turnover of central bank presidents. One important policy implication of this study is the need to develop institutions conducive to greater political stability as a means to reduce the reliance on seigniorage financing of public deficits.  相似文献

Commercialization of innovations frequently stumbles. A prominent recent example are the early (i.e., pre‐3G) mobile phone‐enabled Internet services, whose European take‐up was slower than expected. To determine why, we build a structural model of demand for such services and estimate it using consumer‐level panel data from a pricing experiment. The experiment allows a decomposition of the number of wireless connections into the number of needs—instances where a consumer would establish a connection if the price were zero—and the conditional probability of establishing a connection. We find that needs were plenty and potential consumer surplus several magnitudes higher than that attained. We find that pricing reduced usage substantially and explore potential reasons for the high prices.  相似文献

Why is invention strongly positively correlated with parental income not only in the United States but also in Finland, which displays low income inequality and high social mobility? Using data on 1.45 M Finnish individuals and their parents, we find the following: (i) the positive association between parental income and off-spring probability of inventing is greatly reduced when controlling for parental education; (ii) instrumenting for the parents having an MSc degree using distance to nearest university reveals a large causal effect of parental education on offspring probability of inventing; and (iii) the causal effect of parental education has been markedly weakened by the introduction in the early 1970s of a comprehensive schooling reform.  相似文献
