[eng] Transportation costs and monopoly location in presence of regional disparities. . This article aims at analysing the impact of the level of transportation costs on the location choice of a monopolist. We consider two asymmetric regions. The heterogeneity of space lies in both regional incomes and population sizes: the first region is endowed with wide income spreads allocated among few consumers whereas the second one is highly populated however not as wealthy. Among the results, we show that a low transportation costs induces the firm to exploit size effects through locating in the most populated region. Moreover, a small transport cost decrease may induce a net welfare loss, thus allowing for regional development policies which do not rely on inter-regional transportation infrastructures. cost decrease may induce a net welfare loss, thus allowing for regional development policies which do not rely on inter-regional transportation infrastructures. [fre] Cet article d�veloppe une statique comparative de l'impact de diff�rents sc�narios d'investissement (projet d'infrastructure conduisant � une baisse mod�r�e ou � une forte baisse du co�t de transport inter-r�gional) sur le choix de localisation d'une entreprise en situation de monopole, au sein d'un espace int�gr� compos� de deux r�gions aux populations et revenus h�t�rog�nes. La premi�re r�gion, faiblement peupl�e, pr�sente de fortes disparit�s de revenus, tandis que la seconde, plus homog�ne en termes de revenu, repr�sente un march� potentiel plus �tendu. On montre que l'h�t�rog�n�it� des revenus constitue la force dominante du mod�le lorsque le sc�nario d'investissement privil�gi� par les politiques publiques conduit � des gains substantiels du point de vue du co�t de transport entre les deux r�gions. L'effet de richesse, lorsqu'il est associ� � une forte disparit� des revenus, n'incite pas l'entreprise � exploiter son pouvoir de march� au d�triment de la r�gion l
    • "Hong Kong's growth rate is again assumed to be negatively affected by Hong Kong's initial GDP level (apart from time effects). The initial GDP level is the heart of so-called Barro regressions to test economic growth theories (Barro and Sala-I-Martin, 1991), albeit actually with growth of and the initial level of per capita GDP. Following the literature of Barro regressions, growth of GDP is in this section represented by the instantaneous growth rate, which equals approximatively the compound annual growth rate. "
    [Show description] [Hide description] DESCRIPTION: In a recent contribution in the journal "Empirical Economics", it has been argued that empirical exercises of the author of that contribution would show the ecological fallacy to be a manifestation of Simpson’s paradox for continuous variables. The present paper argues that those empirical exercises show just the opposite, namely they show that the ecological fallacy is not in general a manifestation of Simpson’s paradox for continuous variables. In the alternative, it is shown that the author is right, but for the wrong reason. In any case, the punchline of the present paper is that the relationship between Simpson’s paradox and the ecological fallacy is more complicated than one might think and that using both terms interchangeably is maybe not a good idea.

    • "There is a growing empirical literature on convergence literature. 1 Conceptually, two kind of convergence can be discerned, namely β-convergence and σ-convergence (Barro & Sala-i-Martin, 1991 ). According to Barro and Sala-i-Martin (1991) and Martin (1996), β-convergence occurs if poor economies tend to grow faster than rich ones, such that poor countries " catch up " to the rich ones through time in terms of the real per capita GDP levels, and σ-convergence occurs if cross-sectional dispersion of real per capita GDP levels of a group of economies tends to decrease over time. "
    [Show abstract] [Hide abstract] ABSTRACT: In this paper we investigate whether EU-15 countries experience convergence in per capita GDP levels with respect to the EU-15 average over the period 1950–2015. Nonlinear and nonlinear-asymmetric unit root tests as well as structural break Lagrange Multiplier (LM) unit root tests are employed. When nonlinear and nonlinear-asymmetric unit root tests are employed, five countries exhibit long-run or deterministic convergence with the EU-15 average. However, when endogenous structural break LM unit root tests are employed, nine countries exhibit stochastic convergence. Test results indicate that real per capita income levels of 11 EU countries converge towards the EU-15 average.

    • "additional covariate (Achen, 2001). Closely following the theoretical suggestions by Barro and Sala-i-Martin (1991) , we include in our next specification the laggeddependent variable to observe how the latter approach would change our inference from previous steps. An addition of the lagged-dependent variable to the empirical specification of regional economic development increases goodness-of-fit of the model but the point estimate for the lagged-dependent variable does not have any direct economic interpretation.

    [Show abstract] [Hide abstract] ABSTRACT: This paper assesses the effect of sub-national institutions on the economic performance of Russia's regions (oblasts, republics, krais and okrugs) from 2001 to 2008, a period of rapid economic advancement and recentralization. Approximating sub-national institutions with the RA Expert index of investment risk, we find that a reduction in investment risk by one standard deviation increases output by 1.4 percent in the short run and 11.9 percent in the long run, suggesting a substantial regional performance gap in government practices, despite intensive political recentralization. Assuming that the main components of effective governance are running satisfactory public health programmes aimed at decreasing overall mortality among the working-age population, creating fair labour market conditions and improving the regional institutional climate to encourage investment in fixed assets, we argue that sub-national institutions remain important for growth in post-Soviet Russia after 2000. This paper contributes to the literature on institutional persistence.
