The old and the new: the evolution of polymer and biomedical clusters in Ohio and Sweden

This paper examines the rapid growth of the polymer-based and biomedical clusters in Ohio and Sweden – two regions of similar size and with similar traditions undergoing similar industrial restructuring. Two issues are addressed: First, why has growth been so strong in these particular clusters, i.e., can we identify the sources of the growth and dynamics in these sectors? Second, why do these two clusters differ in Ohio and Sweden in terms of size, level and type of activity, number and composition of actors, size structure of firms and growth patterns over the last couple of decades? In particular, what is the role of public policies as well as cultural, historical, and geographic factors? Our main conclusions are (1) that there is strong path dependence in both clusters in both countries, and (2) that the key to rapid development is a high absorptive capacity combined with rapid diffusion to new potential users. Our policy discussion addresses these issues.     

An evolutionary model of the size distribution of firms

An analytical study of the evolution of the distribution of firm size in an industry is presented. A drift-diffusion model is proposed to express the time-evolution of density of firm size within the industry. The model blends the conventional, more or less static, determinants with the kinds of dynamic considerations introduced by stochastic processes of evolutionary dynamics. The steady-state distribution as well as the dynamic behavior of the model are derived. Parameters in the resulting analytical expressions are then fit to a population of firms in the non-manufacturing service sector. The empirical portion of the paper validates the proposed evolutionary model.     

Growth and equilibrium indeterminacy: the role of capital mobility

Summary. The paper presents a human capital driven endogenous growth model which, in general, permits a multiplicity of equilibrium balanced growth paths. It is shown that allowing for perfect capital mobility across countries increases the range of parameter values for which the model permits equilibrium indeterminacy. As opposed to the closed capital markets case, simple restrictions on preferences are no longer sufficient to eliminate the indeterminacy. Intuitively, under perfect capital mobility agents are able to smooth consumption completely. This induces an economy with open capital markets to behave like a closed economy with linear preferences thereby increasing the possibility of equilibrium indeterminacy.

Capitalism and democracy in the 21st century: a Kaleckian interpretation of a Schumpeterian problem

The paper reinterprets Schumpeter's views on the dynamic effects of taxation, as originally expressed in Crisis of the Tax State, from a Kaleckian perspective. In light of Schumpeter's rejection of Keynesian and Marshallian approaches to taxation, the paper argues that a recently developed Kaleckian approach provides an appropriate basis from which to analyse the effects on the business cycle of balanced changes in the structure of taxation. It is shown that, under certain shifting assumptions, increases in the taxation of wages or profits will stimulate investment and attenuate the amplitude of the business cycle. Ultimately, the shifting of taxes reduces to a conflict over income shares. The changing distribution of income in the United Kingdom in recent years suggests that investment is likely to remain sluggish unless there is a significant reversal of income shares. This may give rise to increasing economic and political tensions into the 21st century.     

Measuring chronic and transient components of poverty: a Bayesian approach

After the publication of Ravallion’s Econ J 98:1171–1182, 1988 seminal work on chronic and transient poverty, wide attention has been given to the components of poverty. We propose a Bayesian mixture model to measure poverty and divide it into chronic and the transient poverty using the Foster, Greer and Thorbecke (FGT) measure. These two types of poverty are illustrated using the Panel Study of Income Dynamics (PSID) data.
