Market size,occupational self‐selection,sorting, and income inequality

We develop a monopolistic competition model with heterogeneous agents who self‐select into occupations (entrepreneurs and workers) depending on innate ability. The effect of market size on the equilibrium occupational structure crucially hinges on properties of the lower tier utility function—its scale elasticity and relative love‐for‐variety. When combined with the underlying ability distribution, the share of entrepreneurs and income inequality can increase or decrease with market size. When extended to allow for the endogenous sorting of mobile agents between cities, numerical examples suggest that sorting may increase inequality within and between cities.     

Eratosthenes’ Contribution to Ptolemy’s Map of the World

This article attempts to shed some light on the origins of Ptolemy’s map of the world, which remains a mystery. The premise is that Ptolemy and other ancient geographers largely drew on the same or a similar pool of sources and common beliefs. Similarities between them can, therefore, give us a key to understanding the prehistory of Ptolemy’s map. Comparison of distances on his map with those given by other sources leads to the conclusion that a large area of the map, approximately from the Bosporus to the Indus, reproduced Eratosthenes’ geographical system, with linear distances converted to angular degrees according to Eratosthenes’ own scale. It is argued that this area represents a remnant of an earlier version of Ptolemy’s map. Analysis of latitude and longitude reveals notable differences between Ptolemy’s map and Eratosthenes’ ideas concerning the latitude of Babylon and the Alexandrian prime meridian, and the impact this seems to have had on the shape of neighbouring regions is noted.     

The causes and consequences of Beslan: A commentary on Gerard Toal's placing blame: Making sense of Beslan

Gerard Toal has written a very important work placing the terrorist attack in Beslan into a geopolitical context. Toal's analysis emphasizes two themes, the need to place Beslan in a political context and the parallels between the Russian government's reaction to the attack and the Bush administration's reaction to the September 11 attacks. In this response, I seek to make these two themes more explicit and also to focus on one area that is somewhat neglected in Toal's analysis: namely, the factors that made the terrorist attack in Beslan possible. In doing so, I turn away from focusing exclusively on geopolitics by bringing in some of the socio-economic and ideological factors that made the North Caucasus ripe for the explosion of terrorist attacks that occurred in the first half of this decade. I also show how changes in government policies eventually brought about the decline of large-scale terrorist attacks in the region. In doing so, I hope to make the point that any analysis of a spectacular terrorist attack such as Beslan has to take into account not just geopolitics, but also the socio-economic conditions that made it possible and the government policies that allowed it to happen.     

Love and Hate of Foreign Lands: The Nineteenth-Century Russian Intelligentsia

Love and hate follow the same patterns among émigrés as among people in general. Among the several models of the love émigrés feel for a foreign land is pragmatic love, based not so much on real attachment as on interests. For an Orwellian Big Brother this love does not necessarily imply direct material benefits but could be an attempt to justify something that has already occurred—emigration, for example. Pragmatic love for a foreign land and people and a corresponding hatred for one's land of origin raises fewer problems than love for its own sake, which often leads to disappointment and a violent emotional response. Everything is reversed in one's mind: the distant motherland becomes desirable, almost an ideal, whereas the foreign land, the place of residence, is hated and despised. Such was often the case for Russian émigrés to the West from the seventeenth through the nineteenth century. Two nineteenth-century Russian intellectuals—Vladimir Pecherin (1807–55) and Alexander Herzen (1812–70)—though different in many ways, came to a similar conclusion: that the West was not the embodiment of goodness but the dead end of history, and that Russia, which they never visited once they had left it, was the shining star of humanity.     

Slavic,European, or Asiatic? F. H. Duchinski on the Origins of the Russian People

The emergence of Russia as a dominant force in Europe from the early nineteenth century onward was characterized by growing tensions between Russians and Poles as seen in the recurring Russian suppression of Polish uprisings. F. H. Duchinski (1817–93) who, like other Polish intellectuals, tried to uncover the root causes of these political tensions, concluded that Russians were neither Slavic nor European, but Asians, and it was this fact alone, he believed, that accounted for the continuing Russian hostility toward the Poles.     

Geochronology of vegetation stages of south-east Baltic coast (Kaliningrad region) during the middle and Late Holocene

The raised bog sediments that have been continuously accumulated over time represent the most suitable natural object which enables us to reconstruct Late Glacial and Holocene vegetation and palaeoclimates. Bog peat consists of organic carbon formed in situ. It contains moss, plant fragments and microfossils that are necessary for the study of palaeovegetation and palaeoclimate. However, a successful study of palaeoenvironment can be carried out on the basis of investigation of a great quantity of samples along the whole peatbog thickness. In the present paper, the authors present the results of palynological, botanical investigations and radiocarbon dating of 31 peat samples taken from the raised bog Velikoye, located in the eastern part of Kaliningrad Region. The data obtained have enabled us to reconstruct the palaeovegetation, reveal the evolution of the bog and determine rate of peat formation at different evolutional stages over the last 7500 cal BP.
