This study introduces a new measure of urban centrality. It identifies distinct urban structures from different spatial patterns of jobs and resident population. The proposed urban centrality index constitutes an extension of the spatial separation index (MIDELFART-KNARVIK et al., 2000). It is...

This article investigates the use of the configurational variable, which deals with the city form-space relations regarding transportation issues, to study spatial segregation and urban accessibility in four Brazilian cities (Belém, Manaus, Recife and São Paulo), with a focus in precarious...

The aim of the present article is to analyze the convergence of regional inflation rates in Turkey from 2004 to 2015 by adopting a distribution dynamics approach, namely discrete time Markovian chains. Convergence across regional inflation rates is politically a crucial matter for two reasons....

Historical city directories are rich sources of micro-geographic data. They provide information on the location of households and firms and their occupations and industries, respectively. We develop a generic algorithmic work flow that converts scans of them into geo- and status-referenced...

This paper develops an oligopolistic model of international trade with heterogeneous firms and endogenous R&D to examine how trade liberalization affects firm and industry productivity, as well as social welfare. We identify four effects of trade liberalization on productivity: (i) a direct...

We study the impact of learning-by-doing with spillovers in competitive markets with free market entry. Within a two period model, we consider first the case where fixed costs are incurred only once, and entry is once and for all. In the second case fixed costs are incurred in each period, and...

This paper builds models of nonlinear dynamics in the aggregate investment and borrower net worth and uses them to study the causes and nature of endogenous credit cycles. The basic model has two types of projects: the Good and the Bad. The Bad is highly productive, but, unlike the Good, it...

The paper investigates spatial changes in cultivation and land use of wheat, maize and oilseed in Hungarian agriculture using different methods to measure these changes. The results suggest that spatial structure of crop productions has remained fairly stable during analysed period. The spatial...

The paper provides historical and analytical perspectives for the assessment of the challenges and opportunities of cattle raising activities in the transition towards a lowcarbon agriculture in Brazil. It is organized as follows. The next section presents long run historical perspectives on the...
