Gazelles as job creators: a survey and interpretation of the evidence

It is often claimed that small and young firms account for a disproportionately large share of net employment growth. We conduct a meta-analysis of the empirical evidence regarding whether net employment growth rather is generated by a few rapidly growing firms—so-called Gazelles—that are not necessarily small and young. Gazelles are found to be outstanding job creators. They create all or a large share of new net jobs. On average, Gazelles are younger and smaller than other firms, but it is young age more than small size that is associated with rapid growth. Gazelles exist in all industries. They seem not to be overrepresented in high-technology industries, but there is some evidence that they are overrepresented in services.     

A plausible model of yield curve dynamics

We present a simple model of yield curve dynamics which satisfies key criteria of plausibility. Specifically, yields are non-negative and the Sharpe ratio of a mean-variance optimal bond portfolio has a reasonable magnitude. The model matches stylized data features, in particular long-run moments of yields and excess returns.     

Attracting private sector participation in infrastructure investment: the UK case

This article examines the potential for private sector organizations to contribute to public sector innovation. Specifically, the study explores how partnering with the private sector can go beyond delivery and extend to development of new services and new markets. The term ‘commercialization partnership’ is coined for such partnerships and the article describes an exploratory investigation of this emerging form of innovation.     

Evaluating market efficiency without price data: the Swedish market for wood fuel

The overall objective of this paper is to analyse the price development and price formation for wood fuel used by the Swedish district heating sector. According to Lönner et al., there is a significant potential for increasing the use of wood fuel in Sweden, at a fairly moderate cost. The basic question raised in this paper is then why this potential is not realized. Specifically, a methodology is proposed for testing whether the reason is that market imperfections are present. As a first step the shape of the technology in the Swedish district heating sector is estimated for the period 1989 to 1996. In the second step the estimated technology and the assumption of cost-minimizing firms are combined to calculate shadow prices, i.e. marginal valuation of wood fuel in this sector. If the average shadow price significantly deviates from the average observed price one may conclude that this market is functioning inefficiently due to imperfections. According to constructed bootstrap confidence intervals this difference is significant only for three out of eight years, implying that the quantities of wood fuel traded are too small. For the other years the difference is not significant, implying that one cannot, on statistical grounds, reject the efficient market hypothesis for all years.     

WEIGHTED‐AVERAGE LEAST SQUARES (WALS): A SURVEY

Model averaging has become a popular method of estimation, following increasing evidence that model selection and estimation should be treated as one joint procedure. Weighted‐average least squares (WALS) is a recent model‐average approach, which takes an intermediate position between frequentist and Bayesian methods, allows a credible treatment of ignorance, and is extremely fast to compute. We review the theory of WALS and discuss extensions and applications.     

Where Schumpeter was nearly right – the Swedish model and Capitalism, Socialism and Democracy<--RID="*"-->

In Capitalism, Socialism and Democracy Joseph A. Schumpeter concluded that socialism would eventually displace capitalism in Western democracies. This would come about as a result of the superior performance of capitalism. We extract six “stylized” propositions that are essential elements of Schumpeter's prediction about the fate of capitalism. These propositions are confronted with the development of the Swedish economy. The three main results of the analysis are: (1) The evolution of the Swedish economy closely followed Schumpeter's predictions until about 1980: Large firms became increasingly predominant in production and innovative activity, ownership of firms became more and more concentrated, individual entrepreneurship waned in importance, the general public grew increasingly hostile towards capitalism, and by the late 1970s explicit proposals for a gradual transfer of ownership of firms from private hands were launched. (2) Design of tax and industrial policies fueled a development of the economy along the lines predicted by Schumpeter. In general, the policies discouraged private wealth accumulation. In particular, the policies favored concentration of firms and concentration of private ownership. (3) The turning point away from the path to socialism coincides with real world developments that disclosed two major flaws in Schumpeter's analysis. First, the ever more obvious failure of socialism in Eastern Europe went against Schumpeter's assertion that socialism can work. Second, Schumpeter, who thought that modern technology would make the giant corporation increasingly predominant, did not foresee the revival of entrepreneurship that took place in the Western countries around 1980.     

National Culture and Takeover Contest Outcomes

We examine the effects of cultural differences on the outcome of takeover contests. Our main focus is on individuality, which we posit to have an effect on firm behavior in international takeover contests. In a sample of international acquisitions with bidders from multiple countries, we find that individuality positively relates to the probability of placing the winning bid. We further find that takeover contest winners with high individuality scores experience lower announcement returns. Our results are consistent with the literature that links individuality to overconfidence. Our evidence suggests that firms should control culture‐related behavioral biases in their mergers and acquisitions activity.     

Welfare Capitalism in Post-Industrial Times: Trilemma or Power Over Rents?

The structure of ‘post-industrial’ economies is widely held to be problematic for welfare capitalism, because of inherent limits to productivity growth in services compared to manufacturing. The so-called post-industrial trilemma is suggested to allow only two of relative earnings equality, high levels of employment and fiscal balance, and has resulted in the widespread policy belief that greater earnings inequality and welfare state retrenchment are unavoidable. This article challenges the micro foundations of this understanding, that the production of economic value is technologically determined by the physical properties inherent in goods and services. In contrast, we argue theoretically, and demonstrate empirically, that production, allocation and distribution are contingent processes better conceived in terms of ‘power over rents’ with associated externalities between sectors. Our analysis suggests that the post-industrial trilemma thesis may have unduly distracted research from the potential for redistributive politics to achieve sustainable levels of productivity growth, fiscal balance and higher levels of earnings equality.     

On levies to reduce the nitrogen surplus: The case of Dutch pig farms

Pig farms in the Netherlands pay a zero or low price for using the environment. As a consequence, the environment is overused. The Dutch government wants to reduce the emissions of nitrogen and phosphorus. Possible instruments are regulation and levies. In this study a levy on feed and a levy on the nitrogen surplus are investigated, by incorporating a bad output in the production model. The model is estimated using panel data of Dutch pig farms over the period 1975–1989. Levies on nitrogen turn out to be more cost-effective than levies on feed.
