Der deutsche Telekommunikationsmarkt im europäischen und internationalen Vergleich

According to current discussions, the German and European market for telecommunications is not as competitive as in the US or Asia. This paper shows — based on official data — that Germany has a high availability of broadband internet connections. It is not the availability but the usage that lags behind. Fixed telephone calls as well as broadband internet connections are rather cheap in Germany, but to be prepared for the digitalisation of the economy and society, more investments in infrastructure are needed. Surprisingly the US does have a higher number of network providers than Europe. What is missing in Europe is a provider that covers all countries of the European Union; current EBITDA does not show that the European market is too fragmented to make a profit.     

Terminierungsentgelte im Mobilfunkmarkt

This article analyses and compares two methods applied by national regulation authorities (NRAs) to determine mobile termination rates: “pure LRIC (long-run incremental costs)” and “LRIC+ (KeL)”. It can be shown that “pure LRIC”, favoured by the European Commission, is not coherent with standard microeconomic theory and hampers competition since “pure LRIC” does not cover all the costs borne by the mobile network operator. NRAs should apply “LRIC+” which is suited to set competition prices (since all costs are covered) and therefore guarantees the highest level of social welfare.     

Trade and the Environment: The Role of Firm Heterogeneity

In this paper, we derive a new effect of trade liberalization on the quality of the environment. We show that in the presence of heterogeneous firms, the aggregate volume of emissions is influenced by a reallocation effect resulting from an increase in the relative size of more productive firms. The relative importance of this reallocation effect and the scale effect well‐known from the literature is affected by the emission intensity at the firm level. Domestic emissions decrease as a result of a unilateral tariff reduction if and only if firm‐specific emission intensity decreases strongly with increasing firm productivity. As a result of the induced change in foreign emissions, domestic pollution can increase even if domestic emissions decrease.     

Do the poor benefit from globalization regardless of institutional quality?

Despite significant progress towards the Millennium goals, more than one billion people live on less than 1.25 US dollars per day. Previous research suggests that globalization stimulates poverty reduction, but does not investigate what role institutions play in this relationship. Theoretically, globalization could act as either a complement or a substitute to institutional quality in reducing poverty. We find that the poverty-reducing effect of globalization is stronger when institutions are weak. In particular, increasing social globalization reduces poverty more when corruption is high and democratic accountability is low. Thus, globalization has the power to reduce poverty even in countries with low institutional quality.     

Integration of Finance with Marketing and R&D in New Product Development: The Role of Project Stage

While the interfaces of marketing, research and development (R&D), and manufacturing in product development have been extensively studied, no large‐scale empirical study has focused on finance's role in the product development team. The present research investigates the role of finance in cross‐functional product development teams, thereby extending existing research on cross‐functional integration in product development. A set of hypotheses is tested with a survey of 389 project team leaders and top management team members from companies in the United States, Australia, New Zealand, Germany, and Austria. The findings suggest that the integration of finance in cross‐functional teams positively impacts project performance and that the importance of the finance interface depends on the project development stage and the innovativeness of the product developed. The results indicate that the R&D–finance interface is most critical at the early stage of a project, while the marketing–finance interface is most important at the late stage, and that the integration between R&D and finance is especially useful in the development of less innovative products.     

Zero‐interest Rate Policy and Unintended Consequences in Emerging Markets

Since 2009, central banks in the major advanced economies have held interest rates at very low levels to stabilise financial markets and support the recovery of their economies. This paper outlines the unintended consequences of the prolonged period of very low world funding interest rates in emerging markets. The paper is informed by a Mises–Hayek‐BIS view on credit booms and Mises' law of unintended consequences. Consistent with the presented credit boom view, I provide evidence that the very low world funding interest rates are associated with a rise in volatile capital flows and asset market bubbles in fast‐growing emerging markets. In line with Mises' law, I further show that these unintended consequences give rise to a new wave of interventionism as policymakers in emerging markets increasingly reintroduce financially repressive measures to isolate the economies from foreign capital inflows.     

EQUALITY OF OPPORTUNITY: EAST VS. WEST GERMANY

The case of German reunification has been subject to extensive research on earnings inequality and labour market integration. However, little is known about the development of equality of opportunity (EOp) in East and West Germany after 1990. Using German micro data, we empirically analyse how circumstances beyond the sphere of individual control relate to inequality in East and West Germany. Our results show that EOp is larger in East than in West Germany. However, despite increasing income inequality, EOp remained surprisingly constant.
