International medical technology diffusion

Does medical technology generated in frontier countries have a significant impact on health outcomes in the rest of the world? This paper considers a framework where non-frontier countries may benefit from medical innovation that is embodied in medical imports or diffuses in the form of ideas. Using a novel dataset from a cross-section of 63 technology-importing countries, we show that medical technology diffusion is an important contributor to improved health status, as measured by life expectancy and mortality rates.     

Beschäftigungs- und Finanzierungswirkungen von Kombilohnmodellen

Derzeit werden verschiedene Kombilohnmodelle zur Bek?mpfung der Arbeitslosigkeit von Niedrigqualifizierten diskutiert. Wie unterscheiden sich diese Modelle? Welche Wirkungen haben sie auf das Arbeitsangebot? Welche Kosten sind damit verbunden?

Mortality-Indexed Annuities Managing Longevity Risk Via Product Design

Abstract

Longevity risk has become a major challenge for governments, individuals, and annuity providers in most countries. In its aggregate form, the systematic risk of changes to general mortality patterns, it has the potential for causing large cumulative losses for insurers. Since obvious risk management tools, such as (re)insurance or hedging, are less suited for managing an annuity provider’s exposure to this risk, we propose a type of life annuity with benefits contingent on actual mortality experience.

Similar adaptations to conventional product design exist with investment-linked annuities, and a role model for long-term contracts contingent on actual cost experience can be found in German private health insurance. By effectively sharing systematic longevity risk with policyholders, insurers may avoid cumulative losses.

Policyholders also gain in comparison with a comparable conventional annuity product: Using a Monte Carlo simulation, we identify a significant upside potential for policyholders while downside risk is limited.     

Anticipating the futures of nanotechnology: Visionary images as means of communication

Reports of the current success and future potential of nanotechnological innovation in the field of medicine are frequently illustrated with images depicting speculative and futuristic visions. Based on a case study of visionary images of nanorobots and mini-submarines in the human body in popular science magazines, the business press and daily and weekly newspapers, this paper demonstrates that, despite their weak reference to current developments in nanomedicine, these images serve as a means of communication for the 'exchange' of expectations between the discourses of science, economy and the mass media.

Through a systems-theoretical and discourse-analytical examination of the dynamics of discourse-networks surrounding these images, the investigation focuses on a certain mediality of futuristic visual images which has been rather neglected in recent Science and Technology Studies (STS) and Technology Assessment. The 'communicative spaces' suggested by visionary images enable productions of meaning for the current potential of nanotechnological innovations in and between various discourses. The dynamics of expectations within the communication processes can be reconstructed according to the variations of discourse-specific (i.e. scientific) evaluations of the depicted visions, which in turn can be described as the recursive processing of other (i.e. economic and mass medial) evaluations.     

Pigouvian Taxes in General Equilibrium with a Fixed Tax Redistribution Rule

This paper establishes existence of a first-best emission tax in a general equilibrium model with pollution, when the redistribution rule of the tax income is chosen fixed and independently of the Pigouvian tax rate. It is known that under standard convexity assumptions each Pareto efficient allocation can be implemented by simultaneously choosing a Pigouvian tax rate and an appropriate lump sum redistribution of income. In real politics, however, tax redistribution schemes are often restricted to a small feasible set. Nonetheless we show that for any given lump sum redistribution rule, being continuous in overall tax income, an emission tax rate exists that leads to a Pareto efficient equilibrium.     

Ethics in International Value Chain Networks: The Case of Telenor in Bangladesh

The spotlight in the CSR discourse has traditionally been focused on multinational corporations (MNCs). This paper builds on a burgeoning stream of literature that has accorded recent attention to the relevance and importance of integrating small and medium enterprises (SMEs) in the CSR debate. The paper begins by an overview of the CSR literature and a synthesis of relevant evidence pertaining to the peculiarities and special relational attributes of SMEs in the context of CSR. Noting the thin theoretical grounding in the literature on offer, the paper then presents relevant CSR theoretical perspectives that could be useful in conducting further research on SMEs. In light of this framework, the paper outlines the findings of an empirical study highlighting the peculiar CSR orientations of SMEs in a developing country context in comparison to some of their MNC counterparts. The study is qualitative in nature, capitalizing on a comparative research design to highlight differences in CSR orientations between SMEs and MNCs. The findings are presented and implications are drawn regarding the peculiar relational attributes of SMEs in the context of CSR generally, and developing countries more specifically, and how this inclination can be further nurtured and leveraged.     

NONLINEAR FORECASTING OF THE GOLD MINER SPREAD: AN APPLICATION OF CORRELATION FILTERS

This paper models and forecasts the Gold Miner Spread from 23 May 2006 to 30 June 2011. The Gold Miner Spread acts as a suitable performance indicator for the relationship between physical gold and US gold equity. The contribution of this investigation is twofold. First, the accuracy of each model is evaluated from a statistical perspective. Second, various forecasting methodologies are then applied to trade the spread. Trading models include an ARMA (12,12) model, a cointegration model, a multilayer perceptron neural network (NN), a particle swarm optimization radial basis function NN and a genetic programming algorithm (GPA). Results obtained from an out‐of‐sample trading simulation validate the in‐sample back test as the GPA model produced the highest risk‐adjusted returns. Correlation filters are also applied to enhance performance and, as a consequence, volatility is reduced by 5%, on average, while returns are improved between 2.54% and 8.11% across five of the six models.
