Decomposing the Rural-Urban Differential in Student Achievement in Colombia Using PISA Microdata

Raul Ramos, Juan C. Duque and Sandra Nieto (2012)

Despite the large number of studies that draw on Programme for International Student Assessment (PISA) microdata in their analyses of the determinants of educational outcomes, no more than a few consider the relevance of geographical location. In going some way to rectify this, our paper examines the differences in educational outcomes between students attending schools in rural areas and those enrolled in urban schools. We use microdata from the 2006 and 2009 PISA survey waves for Colombia.

The determinants of R&D Investment the role of Cash flow and Capabilities

Francesco Bogliacino and Sebastian Gómez Cardona (2010)

In this paper we have estimated a behavioural equation for R&D investment. We assess the impact of liquidity constraints and capabilities, measured respectively as internal cash flow and distance from the technological frontier.

The job creation effect of r&d expenditures

Francesco Bogliacino and Marco Vivarelli (2010)

In this study we use a unique database covering 25 manufacturing and service sectors for 16 European countries over the period 1996-2005, for a total of 2,295 observations, and apply GMM-SYS panel estimations of a demand-for-labour equation augmented with technology.

Innovation and Development. The Evidence from Innovation Surveys

Francesco Boglicino, Giulio Perani and Mario Pianta (2010)

In this article we investigate the existing evidence on innovation produced by innovation surveys in developing and emerging countries in Europe, Asia, Africa and Latin America. We review the relevant literature, discuss methodological issues, and analyse the results for the countries with the most comparable surveys, considering the well established findings of innovation surveys for Europe as a benchmark.

Profits, R&D and innovation. A model and a test

Francesco Boglicino and Mario Pianta (2010)

In this article we investigate – both conceptually and empirically – the relationship between three interconnected elements of the Schumpeterian “engine of progress”: the ability of industries’ R&D efforts to turn out successful innovations; the ability of innovations to lead to high entrepreneurial profits; the commitment of industries to invest profits in further technological efforts. We build a simultaneous three-equation model – with appropriate lags – and we test it at industry level – for 38 manufacturing and service sectors – on eight European countries over two time periods from 1994 to 2006.

Is the wage curve formal or informal? Evidence for Colombia

Raul Ramos, Juan C. Duque and Jordi Suriñach (2009)

The objective of this paper is to analyse the existence or not of a wage curve in Colombia, paying special attention to the differences between formal and informal workers, an issue that has been systematically ignored in the wage curve literature. The obtained results using microdata from the Colombian Continuous Household Survey (CHS) between 2002 and 2006 show the existence of a wage curve with a negative slope for the Colombian economy.

Quality Risk Aversion, Conjectures, and New Product Difusion

Francesco Bogliacino and Giorgio Rampa (2009)

In this paper we provide a generalization of the standard models of the diffusion of a new product. Consumers are heterogeneous and risk averse, and the firm is uncertain about the demand curve: both learn from past observations.

Monopolistic Competition and New Products: A Conjectural Equilibrium Approach

Francesco Bogliacino and Giorgio Rampa (2009)

In this paper we generalize the heterogeneous risk adverse agents model of diffusion of new products in a multi-firm, heterogeneous and interacting agents environment.

Research networks and scientific production in Economics- The recent Spanish Experience

Juan C. Duque, Raul Ramos and Vicente Royuela (2007)

This paper studies Spanish scientific production in Economics from 1994 to 2004. It focuses on aspects that have received little attention in other bibliometric studies, such as the impact of research and the role of scientific collaborations in the publications produced by Spanish universities.

Supervised regionalization methods- A survey

Juan C. Duque, Raul Ramos and Jordi Suriñach (2006)

This paper reviews almost four decades of contributions on the subject of supervised regionalization methods. These methods aggregate a set of areas into a predefined number of spatially contiguous regions while optimizing certain aggregation criteria.

An algorithmic approach for simulating realistic irregular lattices

In this paper, we propose an algorithm, RI-Maps, that combines fractal theory, stochastic calculus and computational geometry for simulating realistic irregular lattices with a predefined number of polygons.

Learning outcomes and dropout intentions: An analytical model for Spanish universities

The dropout rate among Spanish university students is very high compared to the European mean, creating a pressing need for the introduction of policies and programmes aimed at increasing rates of persistence.
