    This paper presents an overview of current models of consumption and investment behavior. First, the stochastic implications of the permanent income model and empirical tests of these implications are discussed. Then the simple theoretical model is extended to include expenditure on consumer durables. In addition, the implications of liquidity constraints and the unpredictability of the rate of return on wealth are discussed. The overview of consumption behavior closes with a critical discussion of the Ricardia Equivalence Theorem. Investment behavior is analyzed using a dynamic optimization model of a firm facing costs of adjustment. This framework integrates the accelerator model, the neoclassical model and the q theory. The model is then used to analyze the interaction of corporate taxes, inflation and investment and also to analyze the effects of uncertainty on investment. The overview of investment concludes with a discussion of inventory investment.

    Macroeconomic Consequences of Ageing and Directed Technological Change Demographic projections foresee a pronounced population ageing process in the coming decades. The associated changes in quantity and quality of labour will have an impact on the long-term economic outlook. This study discusses economic implications of current demographic projections for a set of large industrialized economies, which include the largest member states of the EU, the USA and Japan, as well as Austria as an example of a small open economy. The focus of the study is the interplay between demographic and technological trends. The study extends the methodology of the European Commission’s Ageing Report by considering the effects of size and composition of the working-age population on the productivity growth and productivity effect of the ICT-intensity as a measure of directed technological change

    Information technology mediated customer service is a reality of the 21st century. More and more companies have moved their customer services from in store and in person to online through computer or mobile devices. Using 208 respondents collected from two Chinese universities, this paper investigates customer preference over two service delivery model (either in store or online) on five type of purchasing (retail, eating-out, banking, travel and entertainment) and their perception difference in customer service quality between those two delivery model. Results show that a majority of Chinese students prefer in store and in person for eating out. For ordering tickets for travel and entertainment, they prefer computer/mobile device. For retail purchasing and banking, less than half of the students prefer in person services. In general, the results show that ordering through computer/mobile devices has become more popular in China and has received higher rating for most of customer service quality except security compared to ordering in store. In addition, it is found that there exist a gender difference in purchasing preference and perception in service delivery quality in China
