Social and solidarity economy and the need for its entrepreneuring ecosystem: Current challenges in Brazil
2020
Made available in DSpace on 2020-12-12T02:05:08Z (GMT). No. of bitstreams: 0 Previous issue date: 2020-01-01 This articles purpose is to discuss the state of the art of the constitution of the entrepreneurial ecosystem for SSE and its application in Brazil. One of the major challenges for the creation, continuity and strengthening of Solidarity Economy Enterprises (SEE) is the effective establishment of an entrepreneurial ecosystem for Social and Solidarity Economy (SSE). The construction of the solidary entrepreneurial ecosystem is a complex task, full of challenges, especially when this construction is associated to structural weaknesses inherent to its modus operandi. Case studies of sev…
Finance, globalisation, technology and inequality: Do nonlinearities matter?
2021
Abstract Relying on data for 90 economies over 1970-2015 and panel estimation techniques, we investigate how financial development, globalisation and technology affect income inequality. Our findings reveal significant nonlinearities, consistent with either Ushaped or inverted-U shaped relationships. As such, depending on whether a certain threshold value is achieved, the same determinants of income distribution exert opposite effects in different countries. Globalisation is associated with increasing inequality in most advanced economies, but with falling disparities for the large majority of emerging economies. Technology and financial development lead to increasing inequality for most em…
Oil prices and Spanish competitiveness
2002
Abstract This paper tries to find, using panel cointegration techniques, the factors explaining the real exchange rate of the Spanish peseta following the monetary approach to exchange rate determination developed in Meese and Rogoff (1988). In addition to the real interest rate differential, the real oil price (adjusted accounting for the relative oil dependence of the countries considered) is included as one of the main long-run determinants. The results are favorable to this simple model, stressing the role played by both, demand and supply factors, to explain the behavior of the peseta real exchange rate. However, the results are not homogeneous in the case of the real oil prices: this …
Technological and organizational capital : Where complementarities exist
2018
This study analyzes the complementarities between technological and organizational capital within enterprises. Different components of technological and organizational capital exert distinct—and often opposed—forces on each other. Our empirical results show that greater employee voice promotes firm productivity when combined with information technology, but harms firm productivity when combined with communication technology. On the other hand, flexible work design is positively associated with communication technology and negatively associated with information technology. peerReviewed
The dark side of the sun: How solar power production affects the market value of solar and gas sources
2015
Abstract Using daily data for the Italian wholesale day-ahead power market over the period 2008–2013, we assess the impact of solar production on the market value of solar and gas sources, defined using the concepts of value factor and unit revenues. We find that, on average, solar generation negatively affects the solar source market value, causing a departure from the grid parity condition and mining their competitiveness once public incentives are removed. This negative relation is not constant over time and becomes stronger for increasing solar penetration in the energy mix. Interestingly, the opposite is found when looking at gas. While the relation between solar production and the gas…
Ranking farms with a composite indicator of sustainability
2011
The assessment of sustainability at farm level has been growing in popularity over the last few years. This article contributes to this line of research by building up composite indicators for different facets—social, economic, environmental, and global—of farm sustainability using a methodological approach that combines data envelopment analysis (DEA) and multicriteria decision making (MCDM) methods, and assigns common weights to each individual sustainability indicator. This approach is applied to a database of 163 farms located in the Campos County, a region belonging to the dry lands of the Spanish Northern Plateau, using 12 individual indicators of sustainability. Our findings show tha…
Innovation Complementarity and Scale of Production
2006
We present an econometrically feasible model that uses the information contained in the innovation profile of each firm to test for the existence of complementarity among production and innovation strategies. Our approach is able to distinguish between complementarity and correlation induced by unobserved heterogeneity. We apply the model to analyze the Spanish ceramic tile industry where the adoption of the single firing furnace in the 1980's facilitated the introduction of new product designs as well as opening new ways of organizing production. Our econometric results show that there is significant complementarity between product and process innovation. Small firms tend to be more innova…
No linealidad y asimetría en el proceso generador del Índice Ibex35
2013
This paper analyzes the behavior of Ibex35 from January 1999 to December 2001, in order to check if it follows a different process from random walk so its return is not a white noise and it can be predictable, against the efficient market hypothesis. For that, a nonlinear generating process of return will be considered and a STAR-APARCH model will be specified. This model allows a nonlinear behavior in the conditional mean and in the conditional variance. The empirical results show that the Ibex35 follows a nonlinear and asymmetric process, both in the conditional mean as in the conditional variance, so the weak-version of efficient market hypothesis is rejected. El trabajo analiza el compo…
TESTING FOR REAL INTEREST RATE PARITY USING PANEL STATIONARITY TESTS WITH DEPENDENCE: A NOTE*
2009
In this paper we test for real interest parity (RIRP) among the 19 major OECD countries over the period 1978:Q1–2006:Q1 using both short- and long-run definitions of interest rates. Once the independence hypothesis is rejected among these series, we test for RIRP using panel data unit root and stationarity tests based on common factor models that allow for pervasive forms of dependence. Our results indicate that there is no evidence in favor of the weak version of the RIRP since one of the common factors that have been estimated is non-stationary.
Linear and nonlinear interest rate sensitivity of Spanish banks
2011
Abstract Interest rate risk is one of the major financial risks faced by banks due to the very nature of the banking business. The most common approach in the literature has been to estimate the impact of interest rate risk on banks using a simple linear regression model. However, the relationship between interest rate changes and bank stock returns does not need to be exclusively linear. This article provides a comprehensive analysis of the interest rate exposure of the Spanish banking industry employing both parametric and non-parametric estimation methods. Its main contribution is to use, for the first time in the context of banks’ interest rate risk, a nonparametric regression technique…
