Freedom of Choice in Technology Strategy? An Analysis of Technology Strategy in the Large Commercial Aircraft Industry

Many companies experience difficult situations as a result of their selected strategy. Strategic management theories implicitly assume that companies have a free choice in setting their strategy. Hence, when companies experience difficult situations this is because of management inadequacy. It is questionable whether companies always have a free choice. This research examines this issue by examining the new product strategies of the two main competitors in the commercial aircraft industry. The development of the A380 aircraft was selected to determine to what extent the companies had a choice in setting their product development strategies. The conclusion is that neither has the alleged freedom for setting its strategy. Implications of this finding are that the strategy theory needs to be adjusted for this choice issue, and that management should not always be held fully responsible for the developing events.     

Business incomes in rural Nicaragua: the role of household resources,location, experience and trust

This paper analyses the determinants of business income for rural households in Nicaragua. A sample of 1030 households was studied in order to assess the importance of material and behavioural factors that influence income from business activity. The households are involved in manufacturing, trade, services or have a mixture of businesses. They generally have a low income and asset value. Households supplement their income from wages and agricultural activities. To estimate non-farm business income per employed person we analyse the impact of resources, location, entrepreneurial experience and trust. Our results show that household resources and entrepreneurial experience are significant determinants for business income in all sectors. Trust is also important, particularly generalized trust. The contribution of other forms of trust, such as institutional trust, depends on the sector in which households participate.

Median‐voter Equilibria in the Neoclassical Growth Model under Aggregation*

We study a dynamic version of Meltzer and Richard's median‐voter model where agents differ in wealth. Taxes are proportional to income and are redistributed as equal lump‐sum transfers. Voting occurs every period and each consumer votes for the tax that maximizes his welfare. We characterize time‐consistent Markov‐perfect equilibria twofold. First, restricting utility classes, we show that the economy's aggregate state is mean and median wealth. Second, we derive the median‐voter's first‐order condition interpreting it as a tradeoff between distortions and net wealth transfers. Our method for solving the steady state relies on a polynomial expansion around the steady state.

The influence of debt management on the term-structure of interest rates

Summary This article focuses onthe influence of debt management on the term-structure of interest rates. Four theories are discussed which try to explain the factors influencing the term-structure. It proved that the four theories could be distinguished according to three aspects which have been investigated by means of analysis of variance and of the estiamtion of two reduced form equations with Dutch data during the period 1950 through 1973. It could be concluded that the liquidity preference theory and to a smaller extent the preferred habitat theory fitted the data relatively well. From this it followed that the influence of debt management on the term-structure of interest rates is rather small. This article is an elaboration of a paper written at the end of the author’s study at Groningen State University. He thanks Dr. S. K. Kuipers, Mr. P. W. Otter and Mr. B. S. Wilpstra, all connected with the Groningen State University, for their advice during the writing of the paper.
