Firms increasingly look to collaboration with alliance partners in their quest for breakthrough innovation. But how does the position of a firm in its alliance network weighted by the centrality of its partners—a concept which we term “partner‐weighted alliance centrality”—and the heterogeneities in the types of partners that it cooperates with—in terms of its private‐public collaboration—influence this quest? Using longitudinal data from the U.S. pharmaceutical industry, we build alliance networks in the period 1985–2001 to investigate these questions. We show that, for breakthrough innovation, collaborating with more partners that are more central in alliance networks the better, but only to a point. Beyond that point, we find that the likelihood of achieving breakthrough innovation drops. Furthermore, and looking at the kinds of knowledge provided by the partners in each firm's alliances, we report that firms with a greater share of private partners, relative to public partners, suffer less from the diminishing benefits of collaboration with central partners when developing breakthrough innovation. Taken together, we make novel contributions about how to organize for breakthrough innovation, and provide actionable managerial advice in terms of selecting collaborative partners in alliance networks.  相似文献

Convergence refers to the process of narrowing the differences between International Accounting Standards/International Financial Reporting Standards (IAS/IFRS) and country‐specific accounting standards. The purpose of this study is to measure the formal convergence between Vietnamese Accounting Standards (VAS) and IAS/IFRS using a fuzzy‐based approach. We assess the extent of convergence between VAS and IAS/IFRS from the perspective of a single standard, clusters of standards and the standards as a whole. The levels of standards convergence are clustered into four categories: full convergence, substantial convergence, substantial difference and complete difference. Our results indicate that the level of convergence between the two sets of standards only achieves mid‐level convergence. The findings of this study should help policy makers improve VAS to meet international standards.  相似文献

一年来,关于房地产问题的讨论逐渐升级,不仅参与的人越来越多,而且参与者的身分也越来越复杂:一些市民之间在街头、在报刊、在网上对骂,市民与开发商之间在“打架”,学者们之间在争吵,地方政府与中央政府之间、各部委之间在增加摩擦,开发商与学者之间也在拼命对抗……  相似文献

This paper studies the effectiveness of the implementation of trade facilitation measures in member countries of the Association of Southeast Asian Nations (ASEAN). We evaluate trade facilitation performance and indicate trade facilitation needs and priorities that vary between ASEAN members. In particular, we examine logistics‐related costs in ASEAN and whether the current level of logistics‐related costs could be a burden or an advantage for ASEAN countries. We also identify critical barriers that have impacts on logistics services related to foreign investment and customs across ASEAN. Finally, we propose recommendations for the harmonisation of logistics policies in ASEAN countries aimed at the development of the ASEAN Economic Community.  相似文献

The paper examines whether banking regulations and monetary policy contributed to controlling the fragility of household debt in Korea. The results show that housing loan regulations such as debt to income regulation contributed to a lower household debt delinquency ratio. Lowering the target interest rate provided additional stabilisation of the delinquency ratio. It is recommended that the government adopt an appropriate mix of regulation and monetary policy to control household financial fragility. The financial supervisory services need to be involved in managing debt to income regulation and minimising financial instability and financial market distortions. Further, the monetary authority has to adopt a more effective position in controlling the real lending interest rate and the delinquency ratio of household loans. Such a policy mix will improve effectiveness in controlling financial fragility, especially at a time of financial crisis.  相似文献

This article assesses the consistency between Indonesia’s National Labour Force Survey (Sakernas) and the Indonesia Family Life Survey (IFLS) for analyses of the country’s labour market. I show that Sakernas and the IFLS depict different levels of and changes in labour-market indicators. My estimates of the labour-force participation model, the sector-choice model, and the Mincer model are all statistically different between the two surveys, although the magnitudes are similar for labour-force participation and sector choice. The IFLS shows a much higher return to education than Sakernas, according to the Mincer model. In addition, I find that the cross-sectional sample of the IFLS and the panel sample of the IFLS corrected for attrition yield similar coefficient estimates from all equations. The findings in this article provide an important reference for researchers interested in using Sakernas and the IFLS—either individually or combined—to analyse labour-market issues in Indonesia.  相似文献

Wholly foreign multinational enterprises (WFs), joint-venture multinationals (JVs), state-owned enterprises (SOEs) pay higher wages than domestic private firms in Vietnamese manufacturing. In large samples of medium–large (20+ employees) firms, conditional differentials accounting for worker education and occupation, as well as capital intensity, size, and shares of female workers, were substantially smaller, but positive and significant. Wage levels and differentials varied substantially among industries. Conditional differentials remained positive and significant for WFs and JVs in most of the 11 industries examined, but estimates of SOE-private differentials were insignificant in most industries. Robustness checks using 2007 data yielded similar results.  相似文献
