Technological evolution and interdependence in China's emerging biofuel industry

This study uses the European Patent Office worldwide patent database and applies two-stage interactive data collection methods to reveal the evolving technological interdependence for China's emerging biofuel industry. Three findings are excerpted from our empirical results. First, due to dominant patterns of business ownership, China's biofuel technology is seen as largely based on the evolutionary strength of the foodstuff and chemical fields. Second, China's biofuel technology development has evolved in the mode of ‘forward engineering’, led by Chinese universities rather than initiated by the public research institutes as in the experience of other East Asian latecomers. Third, our patent map and technology trajectory analyses illustrate that China's biofuel technology tends to be application-oriented and highly intertwined with the pharmaceutical industry since the 2000s, which evidences the development of biofuel industry as reciprocally reinforcing China's innovation capability deriving from its prominent chemical sector. By examining endogenous technology capability embedded in the national innovation capacity, this study uncovers public implications for other technology latecomers attempting to build an emerging industry while facing technology uncertainty in a transitional society.     

Gemeinsame Entscheidungen sind bessere Entscheidungen

Verantwortung als Team übernehmen — Ein konstruktives Miteinander von ?rzten und Pflegenden ist keine Utopie. Voraussetzung ist jedoch, dass bei Entscheidungskonflikten jeder bereit ist, seine Position zu überdenken und Kritik – ohne verletzend zu sein – zu üben und anzunehmen.     

Analysis of non-stationary dynamics in the financial system

Novel data-driven analyses, appropriate for detecting economic instability in non-stationary time series, are developed using functional principal component analysis (fPCA) and Synchrosqueezing. fPCA is applied in a new way, aggregating multiple financial time series to identify periods of macroeconomic instability. Synchrosqueezing, a technique which generates a time-series’ time-dependent spectral decomposition, is modified to develop a new quantitative measure of local dynamical changes and structural breaks. The merit of this integrated technique is demonstrated by analyzing financial data from 1986 to 2012 that includes equity indices, securities and commodities, and foreign exchange. Both procedures successfully detect key historic periods of instability. Moreover, the results reveal distinctions between periods of long-term gradual change in addition to structural breaks. These tools offer new insights into the analysis of financial instability.     

Exploring supermarket loyalty card analysis to identify who buys fairtrade

The aim of this paper is to show how supermarket loyalty card data from a panel of over 1.7 million shoppers can be analysed to provide insights to profile the fairtrade shopper in order to enhance making targeted marketing decisions. The paper demonstrates the huge marketing potential that loyalty-card-based shopper segmentation can bring to objectively describe who buys fairtrade products, compared to profiling shoppers through a claimed/reported behaviour data-set. A paired-samples t-test is used to test the degree of appeal of fairtrade tea, coffee, chocolate, drinking chocolates, banana and sugar categories in Tesco to life-stage and lifestyle shopper segments in terms of their retail sales values over 104 weeks. The results show that analysing loyalty cards based on actual behaviour provides a more detailed picture of how specific fairtrade food product categories appeal to the various life-stage and lifestyle shopper segments.     

ANSWERING THE QUESTIONS ON LVT

This article rebuts the arguments against land value taxation expressed by Oliver Marc Hartwich in the December 2006 'Economic Viewpoints'. This rebuttal argues that taxing land as a surplus is both feasible and consistent with modern economic concepts such as marginal productivity. Entrepreneurship is enhanced rather than hampered by eliminating taxes on wages and enterprise and shifting public revenue to the economic rent of land.

Distinguishing characteristics of the Martiniquan economy and constraints on modelling

The decentralization law confers on local elected representatives powers in the fields of economic, social and cultural development. For this purpose we have constructed a large-scale macroeconometric model for Martinique. The purpose of this article is to present the model and discuss its capacity. To begin with we shall set out its general structure. We shall then describe the relationships that have been selected for solving the model. Finally we shall examine the power of the model, first of all in retrospective simulations and then from the point of view of economic policy. The variants selected are: a demand policy, a supply policy and a policy aimed at bringing the Martiniquan minimum wage up to the level of the metropolitan wage.     

Can a Mixed Health Care System be Desirable on Equity Grounds?*

Should health care provision be public, private, or both? We consider this question in a setting where people differ in their earnings capacity and face some illness risk. We assume that illness reduces an individual's time endowment when waiting for treatment. Treatment can be obtained in a competitive private sector (through private insurance) or in the National Health Service (NHS) where it is provided free of charge but after some (endogenous) waiting time. The equilibrium in the health care sector consists of a waiting time in the NHS such that no patient wants to switch health care provider. This equilibrium is governed by two public policies: the income tax system and the size of the NHS. We find that: (i) a mixed system with a small NHS is never desirable; (ii) actuarially fair sickness insurance is never desirable either; (iii) a mixed system with a sufficiently large NHS may improve on a pure public system if the dispersion of earnings capacities is large enough; and (iv) the welfare gains from such a mixed system are not likely to be significant.     

Ideational item The politics of the press

The public press has often been criticized for anti-business bias. A recent study surveyed journalists' political views in an attempt to find sources for such a bias.
