Regional Economics

My main area of specialization is general equilibrium models, with focus on input-output analysis, but I am also experienced in partial equilibrium analysis using econometrics. I work on the intersection of economic systems with environmental/physical systems, integrating energy, environmental, health, demographics and GIS extensions to the framework. I pay particular attention to spatio-temporal aspects of these relationships and on their feedbacks.

This passion for regional modeling steams from the fact that economic systems are intrinsically interrelated and this spatial connectivity can result in interesting unintended heterogeneous phenomena in distinct areas at distinct times.

My most recent works have been focused on location choice, structural change, and on how to assess transient phenomena within I-O models such that seasonal heterogeneity can be captured. The latter is essential when analyzing impacts of unexpected events (natural or man-made) and optimizing recovery.

In this work, I propose a technique to disaggregate annual input-output tables into intra-year tables (quarterly), in order to capture production seasonality and changing economic structure within the year. This is specially important in evaluating impacts and recovery efforts following unexpected events such as floods, earthquakes, etc.

This paper analyzes the growth in gray water discharges between 1995-2009 using a structural decomposition analysis to isolate the main drivers of such increase. We show that domestic demand for food is the main driver of gray water changes in all countries, while relocation of industrial activities to developing nations has disproportionally transferred this burden from developed countries’ manufacturing industries.

This paper proposes an integrated Input-Output-GIS model with health, energy and emissions extensions to estimate the impacts of different location choice of new power plants in Brazil.

Research in Progress

The current availability of longer series of national/regional input-output tables has led to a growing body of the literature analyzing changes in the economic structure and their drivers. In this paper, we modify the original Temporal Leontief Inverse (TLI) methodology and devise a linear decomposition of the annual change. In a single region setting, we can isolate the contribution of structural changes in direct input requirements by sectors or group of sectors. In a multiregional setting, we can study the contribution of trade, foreign countries and technology to a particular industry. The methodology is illustrated by uncovering some hidden effects not captured in the application of the original TLI to Chicago by Okuyama et al. (2006). Finally, we combine the traditiona structural decomposition analysis with the extended TLI to introduce dynamics in the decomposition of technical changes.

The goal of this work is to introduce an Input-Output framework integrating intra-year tables and a cost-share model of employment requirements that yields jobs by contract duration and quarters, and inter-temporal production levels. This model follows the T-EURO method proposed by Avelino (2017) and uses data from the World Input-Output Database and the Continuous Sample of Employment Histories for Spain to illustrate its application.

  • An Extended Input-Output Model to Evaluate the Impact of Pension Spending on the Spanish Economy
    Co-author: Fernando Bermejo Patón

In this work we analyze the role of pensioners in Spain in mitigating the negative effects of the 2008 crisis and their future impact in the economy.
