Cities without land markets : location and land use in the socialist city

The authors describe the structure of Russian cities after 70 years of Soviet development. This is the longest socialist experience on record and its results are of paramount interest to urban economists. In the absence of price signals and of economic incentives to recycle land over time, the administrative-command process has led to a startling pattern of land use. It's central feature is a perverse population density gradient, which rises as one moves away from the center of the city. (Driving from the center of Moscow, one passes through rings of Stalin-era, Krushchev-era, and then Brezhnev-era flats.) The Soviet city is also characterized by rusting factories in prime locations and high density residential areas in distant suburbs. Such a structure tends to maximize the economic and social inefficiency of the socialist city as well as its environmental ill effects. With market-oriented urban reform, real estate prices are now emerging. Their negative gradient signals again the massive scale of past land misallocation in the Soviet city. The experience of socialist cities is also a powerful warning about the ill effects of public ownership and the allocation of land to achieve the"socialization"of land rents.Environmental Economics&Policies,Municipal Financial Management,Banks&Banking Reform,National Urban Development Policies&Strategies,Urban Housing and Land Settlements,Environmental Economics&Policies,Banks&Banking Reform,Municipal Financial Management,Urban Housing and Land Settlements,National Urban Development Policies&Strategies

Multi-Regime Common Cyclical Features

In this paper we consider the hypothesis that particular short-run co-movements indicationg that shocks have similar responses might only exist for a particular regime and not for the whole sample. A two-step procedure is set up to test and estimate the multi-regime common cyclical feature. This approach is illustrated by analyzing the stability of the McCallum''s (1994) monetary policy reaction function for Danish data.Economics ;

Detection of Change--Points in the Spectral Density. With Applications to ECG Data

We propose a new method for estimating the change-points of heart rate in the orthosympathetic and parasympathetic bands, based on the wavelet transform in the complex domain and the study of the change-points in the moments of the modulus of these wavelet transforms. We observe change-points in the distribution for both bands.Comment: proceeding of the workshop 'Fouille de donn\'ees temporelles et analyse de flux de donn\'ees' EGC'2009, january 27, Strasbourg, Franc

Simulation de pluies sur le bas fond de Keur Samba Diama du 06/03/1990 au 16/03/1990

La nouvelle campagne de simulation de pluie dans le bas fond de Keur Samba Diama (Sine Saloum-Sénégal) fait suite aux mesures réalisées sur les bassins versants de Ndiba en 1988 et Keur Dianko en 1989 dans le cadre du programme bas-fond au Sénégal. Ces mesures ont été effectuées sur trois parcelles avec le nouveau simulateur construit au laboratoire d'hydrologie du Centre ORSTOM de Dakar Hann. Ce rapport présente le déroulement de la campagne de mesures et consigne l'ensemble des résultats obtenus sur le bas-fond de Keur Samba Diam
