Recent econometric literature has demonstrated the existence of significant technological spillovers within and around groups of advanced (R&D-intensive) firms. I demonstrate thatcompetence blocks of advanced firms operate as technical universities and research institutes, unintentionally providing free educational and research services, often in areas where such services are not supplied by existing educational institutions or where the nature of competence makes traditional educational institutions incapable of supplying them. I demonstrate that the competence that diffuses from such competence blocks is botheconomic andtechnological, that it only diffuses under particular market circumstances, notably characterized by competition, and that the outcomes are typically experimental.Integrated production is an organizational technique to coordinate complex production in mechanical engineering industry within firms and over specialized consultants and subcontractors in the market. Such organizational competence is typically tacit and difficult to communicate outside its production context. Hence, such a production organization often functions as a competence block that spills knowhow throughout the industry. This organizational form is also very useful in illustrating the nature of the firm, the nature of the organizational competence that forms the backbone of western industrial technology and how that competence generates economic growth through the intermediation of firms. I use Swedish aircraft industry as a case illustration.

An evolutionary two-sector model is used to study the impact of skill-biased technological change on the growth and inequality paths of a middle-income developing economy. We present four scenarios resulting from changes in a country’s structural conditions and the characteristics of the shock. We show that wage inequality is neither a necessary nor a sufficient condition for growth. A Kuznets dynamic may emerge in the long run in the case of successful catching-up to the high-growth steady state. However, this only happens if adjustment costs significantly hamper the process of skill upgrade. The business cycle and the process of structural change may give rise to sizeable rises in wage inequality in the short term, even when the economy does not break out from the low-growth steady state.

In recent decades, several scholars have formalised Minsky’s profound insight that increasing financial fragility accompanies periods of economic stability. It must be noted, however, that incisive assessments of the role of expectations formation with heterogeneous agents has been provided only by those contributions focusing on stock-market prices. Macroeconomic models dealing with debt dynamics, on the other hand, have not yet presented such an account. It is our purpose to fill this gap in the literature by formalising switches between different heuristics in a small-scale evolutionary agent-based model where solvency aspects matter. Our system generates time-series that reproduce important empirical stylised facts such as fat tails and asymmetric skewness. We show how changes in risk perception are amplified in an asymmetric way by the right-skewed solvency constraint, leading to output fluctuations compatible with the possibility of crashes. Moreover, while the destabilising role of extrapolative behaviour is part of conventional wisdom, we discuss the conditions under which fundamentalists, the existence of resource constraints, and the time horizon of the economic unit may also lead to instability.

The main purpose of our paper is to present a model which allows a comparison of different types of technology policies to be made. It appears that there is a kind of model which is appropriate to that purpose but which belongs to the theory of the firm. Indeed, one of the characteristics of technology policies is the degree of centralization of decision; as it is in the design of firm organization. It seems that a model like AOKI's (1986) presents sufficient properties to be used in our context. The aim of this exercise is to compare vertical and horizontal institutional frameworks for technology policies, more precisely diffusion and mission oriented policies. This framework will be applied to the case of some technology policies in the Federal Republic of Germany (before re-unification): programmes in production technologies and the Transrapid programme.

The Allais paradox constitutes a central violation of the expected utility paradigm. The paradox is typically explained by subjective probability weighing, and has motivated and shaped the leading non-expected-utility models. But why do people weigh probabilities? We suggest a new explanation for the Allais paradox based on evolutionary theory. We show that the evolutionary goal of maximizing the probability of having descendants forever (i.e. minimizing the probability of eventual extinction) predicts the Allais paradox and the common-consequence and common-ratio effects, and thus provides a rational-expectations theoretical foundation for the experimentally observed behavior.

In the United States, the ratio of consumption to GDP has risen steadily over the past half century. In trying to understand why this ratio has increased so much, it is argued that standard models of the consumption function, built up from the neoclassical theory of constrained optimization, cannot offer a satisfactory answer. An alternative perspective is offered whereby aggregate consumption expenditure is seen as primarily the outcome of the population adopting widely upheld rules (‘meso-rules’) in a complex economic system. Aggregate consumption is viewed as the outcome of two contrasting historical processes: one mainly involving pre-committed, rule-bound choices and the other involving open-ended choices, made knowingly in the face of uncertainty, to adopt new meso-rules concerning the consumption of novel kinds of goods and services. The former process provides the degree of order that must be present in any complex system and the latter facilitates evolutionary change to occur. Using over half a century of data, the US consumption function is modelled successfully on the presumption that the economy is a complex system. The evidence supports the hypothesis that the ratio of consumption to GDP has risen because of the diffusion of a ‘culture of consumerism’ in the post-war era and that the limit of this process is now being approached, with important macroeconomic and social implications.
