This paper estimates for 28 product groups a characteristic parameter that reflects the topological structure of its trading network. Using these estimates, it describes how the structure of international trade has evolved during the 1980–2000 period. Thereafter, it demonstrates the importance of networks in international trade by explicitly accounting for their scaling properties when testing the prediction of the “Heckscher–Ohlin” model that factor endowment differentials determine bilateral trade flows. The results suggest that factor endowment differentials increase bilateral trade in goods that are traded in “dispersed” networks. For goods traded in “concentrated” networks, factor endowment differentials are less important.  相似文献

Mit dem Bilanzrechtsmodernisierungsgesetz wollte der Gesetzgeber unter anderem eine im Verh?ltnis zu den IFRS gleichwertige, d. h. ebenso entscheidungsnützliche, aber einfachere und kostengünstigere Alternative bieten. Um dieses Ziel zu erreichen, wurden verschiedene Wahlrechte gestrichen, Bilanzierungsverbote aufgehoben und Bilanzierungsmethoden ver?ndert. Aus Sicht der Abschlusspolitik wurden damit einerseits explizite Wahlrechte verringert und andererseits implizite Wahlrechte geschaffen. Zudem bergen auch die übergangsvorschriften abschlusspolitisches Potenzial. Nach einer Einordnung der Abschlusspolitik und der Herausarbeitung der konkreten Potenziale werden die Konsequenzen in Bezug auf die Entscheidungsnützlichkeit diskutiert und die m?glichen Auswirkungen der ge?nderten Rechnungslegungsnormen am Beispiel der Bilanzierung von Pensionsverpflichtungen deutscher IFRS-Anwender empirisch belegt.  相似文献

We use data from the 2006 round of the Russian Longitudinal Monitoring Survey to describe perceptions of the Russian population about the transition process and the role of the state compared with that of free markets. We find that about one‐half of the Russian population is disappointed with transition and a large majority is in favour of high state regulation and state provision of goods and services. High demand for government regulation and increased state intervention coexists with a low level of trust in government institutions and recognition of high and rising levels of corruption. The findings are consistent with the theory developed by Aghion et al. (2009) . In an environment with poor social capital, private business imposes negative externalities on the society and society chooses to demand more state regulation and tolerate corruption to reduce these externalities. We also find that individual perceptions of social capital and corruption co‐vary with the demand for regulation, as predicted by the theory.  相似文献

This article analyzes the adoption of B2B-e-business technology in German automotive supplier companies during the internet hype period, i.e. in the very early stage of technology diffusion. While from the outset e-business was assumed to be used by companies in order to increase efficiency and reduce costs, some previous IOS research and theoretical considerations suggest that both efficiency and environmental expectations can be important reasons for companies to implement e-business. On this backdrop, the paper analyzes the reasons for e-business technology adoption, focusing on the explanatory value of institutional factors like mimesis, coercion, and normative pressures. Theoretically based hypotheses are developed and tested using regression models with a quantitative data set of more than 1900 companies.The article tries to make an innovative contribution to the field of IOS research, first, by drawing on theories of organizational structuring — new institutionalism, social psychology, and transaction cost economics; second, variation of adoption rationales in different types of companies and different business functions inside a company is taken into account.It appears that the adoption of e-business is explained by external pressures from other customers, bandwagon effects and herding behavior during the e-business hype, and expectations and interests of professionals inside a company. In the ‘core’ areas of a firm, efficiency rationales play an important role, too. The data reveals that the reasons of e-business usage differ significantly by department and company type.  相似文献

A number of western industrialized nations have found themselves in a similar position to the United States today: an aging population leading to increasing, and perhaps unsustainable, expenditures on a traditional social security system. This article examines the risks that individuals face in retirement, describes the role of annuities in addressing those risks and examines why annuitization rates are so low. It then reviews the pension structures in the United Kingdom, Australia and New Zealand--countries with similar governmental and economic structures to those of the United States--and describes how these have impacted those countries' annuitization rates.  相似文献

Manufacturing firms increasingly engage in service trade activities. Microlevel data show that German manufacturers accounted for nearly 30 billion euros of service exports in 2005. I have found that particular construction, engineering and R&D services are exported. The machinery industries, motor vehicles and chemicals producers dominate the overall pattern. The types of services exported vary strongly across industries. Service exports of advertising, data processing, management and R&D services are found to likely support foreign affiliates of firms. However, these headquarter services are only infrequently observable. Much more important are construction and engineering services exported by machinery firms. These might represent installation and maintenance services complementing exported machinery. R&D services exports generally represent the transfer of knowledge and technology, which is found to be particularly relevant for motor vehicle producers. Beyond the support of foreign production of firms, R&D services might be relevant also in R&D cooperations of firms or when firms have partnerships with foreign suppliers or buyers of intermediate products.  相似文献

In line with the wider macro productivity literature existing studies of agricultural production largely neglect technology heterogeneity, variable time‐series properties and the potential for heterogeneous but correlated total factor productivity (TFP) across countries. Our empirical approach accommodates these difficulties and seeks to model the nature of the cross‐section dependence in a sample of 128 countries (1961–2002). Our results suggest that agro‐climatic environment drives similarity in TFP evolution across countries with heterogeneous production technology. This provides a possible explanation for the failure of technology transfer from advanced countries of the temperate ‘North’ to arid and/or equatorial developing countries of the ‘South’.  相似文献
