Prospects for international maritime shipping

The world’s energy supplies are dependent not only on the producer countries’ production capacities and policies but also on adequate transport facilities. In fact, a shortage of vessels able to carry coal is widely expected to be a major bottleneck for the substitution of oil by coal on a large scale. Shipowner Peter M. Nomikos holds a different view.     

Age heaping and numeracy: looking behind the curtain

Age‐heaping‐based numeracy indicators have served as valuable tools to derive basic human capital estimates, especially for periods where other indicators are unavailable. However, the accuracy of individual age statements usually remains unknown, and due to the lack of precise information it can only be assumed that excessive occurrence of multiples of five in age distributions reflects inferior numerical skills. This article addresses this lacuna by identifying 162 individuals in two independent data sources: self‐reported age statements and independently kept records which are based on family heritage books and church registers. This method makes it possible to identify individual misreporting and the degree of accuracy of each individual. Findings show that not everyone who reported a multiple of five was reporting an incorrect age, nor was it the case that everyone who reported an age that was not a multiple of five was reporting an accurate age. The empirical analysis shows that the commonly used binary numeracy indicator is correlated with the observed degree of accuracy in age statements, and that a more sophisticated occupational background reduces this inaccuracy. These results tentatively suggest that the commonly used binary indicator measuring age heaping is a valuable proxy for numerical skills and occupational background in a population.     

Unemployment duration and unemployment insurance: a comparative analysis based on Scandinavian micro data

Based on pooled register data from Norway and Sweden, we findthat differences in unemployment duration patterns reflect dissimilaritiesin unemployment insurance (UI) systems in a way that convincinglyestablishes the link between economic incentives and job searchbehaviour. Specifically, UI benefits are relatively more generousfor low-income workers in Sweden than in Norway, leading torelatively longer unemployment spells for low-income workersin Sweden. Based on the between-countries variation in replacementratios, we find that the elasticity of the outflow rate frominsured unemployment with respect to the replacement ratio isapproximately one in Norway and 0.5 in Sweden.     

International Saving, Investment and Trade

Feldstein and Horioka (Econ J 90:314–329, 1980) observed that saving and investment move closely together in the major OECD countries. This finding is a puzzle if national economies are characterized by one sector neoclassical production functions—with diminishing returns to capital, a high level of savings in a country should create an incentive to export capital. In this paper, we show that this incentive disappears in the presence of multiple sectors with differing capital intensities. In a high saving country, national capital can be absorbed domestically without a decline in its marginal product through a shift in the sectoral composition of national production towards capital intensive sectors. This is nothing but the well-known Rybczynski effect. We present a modified version of the standard Heckscher–Ohlin (HO) Model to show that very small barriers to capital mobility are enough to force national savings to stay within the country of origin. We also argue that, while the assumptions of this model may appear special, they are not unrealistic for the developed countries in the Feldstein Horioka study. Some historical economic trends are also consistent with the picture presented in this paper. Finally, the paper shows that the conventional insights from the one sector neoclassical model can be completely overturned in a multi-sector setting when technological differences are introduced.
