Regime-switching and interest rates in the European monetary system

This paper examines the impact that a currency target zone has on short-term interest rates. For a number of countries in the European Monetary System, we characterize the short rate using a regime-switching model that allows for a differently parameterized mean-reverting square-root process in each regime. We find that the volatility, the level, and the speed-of-adjustment are all higher in the regime that is operative during speculative attacks and currency crises. Moreover, we allow the conditional probability of being in each regime to be state-dependent so the model can be used to examine questions relating to the likelihood of realignments and the stability of the target zone system.     

Creative Destruction, Investment Volatility, and the Average Age of Capital

In this article, a new numerical procedure is used to compute the equilibrium of a vintage capital growth model with nonlinear utility, where the scrapping time is nonconstant. We show that equilibrium investment and output converge nonmonotonically to the balanced growth path due to replacement echoes. We find that the average age of capital is inversely related to output, which is consistent with recent micro evidence reinforcing the importance of the embodied question. We also find that an unanticipated permanent increase in the rate of embodied technological progress causes labor productivity to slowdown in the short run.     

William J. Baumol: An Entrepreneurial Economist on the Economics of Entrepreneurship

William J. Baumol is the 2003 winner of the International Award for Entrepreneurship and Small Business Research. Throughout his career Baumol has urged the profession to pay attention to the instrumental role of entrepreneurship in economic renewal and growth. At the same time he has insisted that economists continue to use their usual tool box when the purview of analysis is extended to entrepreneurship. Hence, Baumol can be characterized as a revolutionary from within. In this article we present and discuss Baumol's research contribution in the areas of entrepreneurship and small business economics, notably from a growth perspective. In addition to placing his work in these areas into the wider context of his full contribution, we emphasize Baumol's findings that growth cannot be explained by the accumulation of various factors of production per se; human creativity and productive entrepreneurship are needed to combine the inputs in profitable ways. As a result, an institutional environment that encourages productive entrepreneurship and human experimentation becomes the ultimate determinant of economic growth.     

Determinants of the Prevalance of Start-ups and High-Growth Firms

The purpose of this study is to identify key institutional determinants of firm emergence and growth. We do this using various types of data from Sweden. A characterization of a number of institutions and policy measures shows that they are likely to have contributed to an environment that discourages entrepreneurial activity and firm growth. Aspects dealt with include: missing arenas for entrepreneurship in the care sectors and for household-related services, taxation of entrepreneurial income, incentives for wealth accumulation, wage-setting institutions and labor market regulations. Using original data, we provide evidence of a low prevalence of nascent entrepreneurs and a small net employment contribution by high-growth firms. We admit that indisputable evidence for the effects of institutional arrangements is almost impossible to establish. However, the consistency of our theoretical arguments and empirical data makes a strong case for the notion that the Swedish case illustrates the costs of giving too little weight to economic renewal in policy making.     

The use and development of indicators for the commercialisation of university research in a national support programme

Governments in most countries have set up specialised programmes to support the commercialisation of academic research. A key challenge is to develop indicators that are able to measure operation and impact. This study shows how different indicators are used to satisfy different stakeholders of a Norwegian support programme. Policy intervention is supposed to lead to additionality related to input, behaviour and output. While the support programme uses input and behavioural measures as strategic tools for its operation, policy makers are mostly preoccupied with output measures. This study illustrates how indicators develop over time, partly co-evolving with the development of the programme and the national commercialisation infrastructure. Indicators serve as incentives for the agents involved, but they may also influence the strategies of the programme that established them. The external signalling effect of indicators remains central, while its use in daily operations becomes less important with time and experience.     

Ethnic discrimination in hiring,labour market tightness and the business cycle - evidence from field experiments

Several studies using observational data suggest that ethnic discrimination increases in downturns of the economy. We investigate whether ethnic discrimination depends on labour market tightness using data from correspondence studies. We utilize three correspondence studies of the Swedish labour market and two different measures of labour market tightness. These two measures produce qualitatively similar results, and, opposite to the observational studies, suggest that ethnic discrimination in hiring decreases in downturns of the economy.     

Extraordinary politics and durable reform: lessons from trade liberalisation in Estonia and Poland

This article analyses the significance of the period of extraordinary politics after the fall of communism for policy reform. It examines under what circumstances policy reforms enacted during such periods are durable by comparing trade liberalisation in Poland and Estonia in the early 1990s. The article relates this question to the historical institutionalist debate surrounding critical junctures, gradual change and the politics of stability and change. It argues that trade policy reform enacted during periods of extraordinary politics is most likely to be durable if it is associated with deeper changes in structural conditions, such as dominant ideas, interests and institutions.     

Epistemic habits: primary school teachers’ development of pedagogical content knowledge (PCK) in a design-based research project

Generalist primary school teachers often have little or no training in school subjects such as science and technology. Not surprisingly, several studies show that they often experience difficulties when teaching these subjects, in fact some primary teachers even avoid teaching them. The over all aim of this study is to contribute to new theoretical and methodological tools for the study of how teachers develop knowledge for teaching, i.e. pedagogical content knowledge (PCK). And based on this, elaborate on implications for the professional development of primary school teachers. The teachers in the study participated in a design-based research project concerning technology education in Grade 1. We were especially interested in whether the teachers displayed any habits that contributed to the development of their personal PCK. We found three significant patterns in how the teachers, together with the researcher, developed knowledge of how to teach a specific topic in technology. We argue that these patterns tell us something about the teachers’ epistemic habits in relation to the teaching of technology. The existence of these habits could help to explain how teachers with little or no experience of teaching a subject can develop relevant PCK.
