Assessing the impact of patent infringement on new product sales

In order to assess the impact of patent infringement on the growth of a new product, a model is developed through the intervention model development processes of Box-Jenkins and Box-Tiao. Physical interpretations of model parameters and determination of associated damages suggest that the model can provide a sound basis for analyzing patent infringement disputes.

Can oil shocks explain asymmetries in the US Business Cycle?

We consider whether oil prices can account for business cycle asymmetries. We test for asymmetries based on the Markov switching autoregressive model popularized by Hamilton (1989), using the tests devised by Clements and Krolzig (2000). We find evidence against the conventional wisdom that recessions are more violent than expansions: while some part of the downturn in economic activity that characterises recessionary periods can be attributed to dramatic changes in the price of oil, post-War US economic growth is characterized by the steepness of expansions.

Business models for material efficiency services: Conceptualization and application

Despite the abundant research on material flows and the growing recognition of the need to dematerialize the economy, business enterprises are still not making the best possible use of the many opportunities for material efficiency improvements. This article proposes one possible solution: material efficiency services provided by outside suppliers. It also introduces a conceptual framework for the analysis of different business models for eco-efficient services and applies the framework to material efficiency services. Four business models are outlined and their feasibility is studied from an empirical vantage point. In contrast to much of the previous research, special emphasis is laid on the financial aspects. It appears that the most promising business models are ‘material efficiency as additional service’ and ‘material flow management service’. Depending on the business model, prominent material efficiency service providers differ from large companies that offer multiple products and/or services to smaller, specialized providers. Potential clients (users) typically lack the resources (expertise, management's time or initial funds) to conduct material efficiency improvements themselves. Customers are more likely to use material efficiency services that relate to support materials or side-streams rather than those that are at the core of production. Potential client organizations with a strategy of outsourcing support activities and with experience of outsourcing are more keen to use material efficiency services.

A Markov–switching vector equilibrium correction model of the UK labour market

There is a wide literature on the dynamic adjustment of employment and its relationship with the business cycle. In this paper we present a statistical model that offers a congruent representation of part of the UK labour market since the mid 1960s. We use a cointegrated vector autoregressive Markov-switching model in which some parameters change according to the phase of the business cycle. Output, employment, labour supply and real earnings are found to have a common cyclical component. The long run dynamics are characterized by one cointegrating vector relating unemployment to trend-adjusted real wages and output. Despite there having been many changes affecting this sector of the UK economy, the Markov-switching vector-equilibrium-correction model with three regimes (representing recession, normal growth, and high growth) provides a good characterization of the sample data, and performs well relative to alternative linear and non-linear models. The results of an impulse-response analysis highlight the dangers of using VARs when the constancy of the estimated coefficients has not been established, and demonstrate the advantages of generating regime dependent responses.

The new logic of Japan's young generations

Through daily use of computer games and advanced cartoonized learning, the lower teen generation in Japan has developed an unprecedented ability for instantaneous contextual gestalt-based decision making and high-speed multidimensional simultaneous thinking. This is a radical departure from the sequential logic of older generations. This is a conclusion we can reach after examining the voluminous data available from a new research institute in Japan. The data also indicate that the young adult generation has developed unique strategies of life, which are fascinating but difficult to understand in the framework of our traditional logic but make sense as a transition to the logic of the lower teen generation.     

Business cycles in Italy: A statistical investigation

This paper conducts a statistical analysis of post-war economic fluctuations in Italy. It is argued that business cycles in this country qualitatively conform to the general character of the phenomenon, a result which confirms existing evidence. A temporal stability analysis of stylized facts shows that some statistically significant changes in the empirical regularities occurred after 1973, but they did not alter the main qualitative features of the business cycle. The evidence thus supports interpretative models of the Italian business cycle which incorporate a stable propagation mechanism.
