However wide the ideological distance between positive and negative prognosticators of employment growth, the pragmatic center is where the White House preferences are likely to fall. Obama??s pragmatic center may be far from the ideological center between public-private program alternatives. Instead, it is closer to the pressure center of partisan and interest-group forces that normally participate in fiscal policy-making. As a behavioral pragmatist the moderate position for Obama is found at the center of ideologically separated political competitors whatever the content of their beliefs, since content is relatively uncritical in this perspective. Pressure groups?? numbers and organizational strength define the value of their diversity more than the substance of their beliefs. For the strong believers on both political left and right the outcomes will rarely look pragmatic because they will rarely fit the traditional standards for moderation  相似文献

This study examines the impact of family management on digital transformation with specific regard to the firm’s development of Internet of Things (IoT) innovations. Drawing on the distinctive characteristics of firms with family managers, such as the focus on family‐centered noneconomic goals, long tenure, emotional ties to existing assets, and rigid mental models, it hypothesizes that increasing family involvement in the top management team is negatively related to the development of IoT innovations that are distant from a firm’s existing technology base (i.e., exploratory IoT innovations) compared to exploitative IoT innovations. Further, the study proposes that the firm’s degree of technological diversification, especially in unrelated forms, reinforces this relationship. The longitudinal analysis between 2002 and 2013 on a sample of publicly traded German firms allows us to test our hypotheses from the beginning of the emergence of the IoT concept. Our findings show that due to the particular characteristics of their managers, family‐managed firms do not welcome the risks related to exploratory IoT innovations, and the benefit of risk diversification from technological diversification is lower than the cost of abandoning family‐centered goals. As our results imply that the involvement of family managers constrains the development of exploratory IoT innovation, the top management team composition in firms that intend to be at the forefront of the digital transformation should be accurately designed by avoiding a high proportion of family members.  相似文献

External technology acquisition has been proved to be an important strategy to enhance firms’ innovation performance. However, previous studies claim that companies acquiring technologies tend to not carry on with this strategy over time, thus limiting their attitude toward continuous technology acquisition. Moreover, the extant literature also highlights that this attitude is strongly influenced by their organizational structure. Therefore, in the present paper, we investigate the relationship between how firms organize R&D activities and continuous technology acquisition. Specifically, given the increasing globalization of technological development, we focus on the role of R&D geographic dispersion, and how its influence is moderated by firms’ technological diversification. We tested our hypotheses on longitudinal data of 303 biotechnology firms that acquired, at least, one USPTO patented technology over the period 1982–2012. Results reveal that R&D geographic dispersion is curvilinearly (inverted U-shaped) related to continuous technology acquisition, with negative returns occurring earlier in technology-diversified companies.  相似文献

We investigate the cash holdings policy of family firms and examine potential value implications. Family firms hold more cash than other firms, with an average difference of 2.3% of total assets. This result is driven by firms managed by heir CEOs. While the cash holdings policy of first‐generation family firms is more sensitive to firm risk, consistent with founders’ increased risk aversion, that of later‐generation firms is more sensitive to information asymmetry and agency conflicts. Heir CEOs’ cash policies destroy value, as the marginal value of an additional Euro suffers from a 38.3‐cent discount, on average, relative to non‐family firms.  相似文献

This paper contributes to the rising field in international trade and industrial organization. A vast sample of Italian micro data is used to study the behavior of relative export prices in imperfect markets. It is shown that relative export prices, the relation of prices a firm charges on export and domestic markets, are, in general, downward biased. Moreover, relative export prices depend negatively on firm size and market concentration, but positively on the average export share of the industry. This indicates that markets are segmented and firms are able to discriminate prices.  相似文献

In this research we use a data-base that reveals the propensity for contractual ventures and direct investments (1051 operations) of the clothing Italian companies during the period 1987–1991, on a national (342 operations) and international level (709 operations). The latter were analyzed with reference to the internal (412) and external growth strategies (297), cooperative (362) and non-cooperative (347) deals. Our analysis focuses on the different strategies that SMEs, on one hand, and large companies, on the other hand, show in the internationalization process. Main results of the study are:
  • the international growth of the SMEs takes place mainly through contractual agreements (68%), more so than with non-cooperative operation (32%), whereas in large companies the non-cooperative strategies slightly prevail (54%). Consequently, the external growth strategy is very important for the SMEs (72%) and somewhat less important for the large companies (54%);
  • the cooperative growth is usually seen by SMEs as an expansion both of the commercial (48% of the operations involves commercial purposes) and of the production areas (48% of the cases). This could indicate that SMEs try to organize on an international level the same network model used in Italy: SMEs decentralize their production within the country through networks of companies and industrial districts, whose horizontal connections (among SMEs themselves) and vertical connections (with large companies) provide flexibility and low costs;
  • large companies' expectations of the Single European Market have brought a great number of international operations in Europe (24%), notwithstanding the notable importance of Japan (23%) and U.S. (17%); on the contrary, SMEs focus on “niche and rich markets” as Japan (40%); but as far as the contractual agreements are concerned, both types of firm privilege the Japanese market: almost 50% of SMEs' international agreements are directed towards Japan (33% in the large company's case);
  • large companies and SMEs in the middle and high segments of the market carry out more operations than companies operating in the low quality and casual segments;
  • generally speaking, in Italy there is an urgent need for industrial policies promoting SMEs access to cooperative instruments (“learning by cooperating”).

    More than 20 years after their introduction, directly elected mayors are key players in Italian urban governance. This article explains the main effects of this reform on local government systems and provides lessons for other countries considering directly elected mayors.  相似文献

    Drugs available in the market today, selected several years ago under very uncertain future scenario, have experienced a long and expensive process of research and development carried out following both a closed and an open innovation path. To support this critical selection process, we propose a Decision Support System, able to choose among different candidates the most promising drugs along their best development path. The Decision Support System, based on a real options portfolio optimization model, mapping tools, and what‐if rules as well, has been applied to a numerical example available in literature, and the research findings show interesting managerial and academic implications.
