Why does the Euro fail? The DCCA approach

The present crisis in the Euro is one of the most serious crises reported in history. The fact that different countries that adopted the Euro have different conditions to support asymmetric shocks in their economies could explain some of the consequences currently affecting the Eurozone. In this paper we apply detrended cross-correlation analysis and its cross correlation coefficient to evaluate the degree of financial integration of the first set of countries to adopt the common currency. Since time series used in these studies are known to be non-stationary, DCCA is suited to study it. It is the first time this methodology has been applied to study financial integration. We conclude that the degree of financial integration is unequal in several countries using the common currency. The fact that countries like Greece, Ireland or Portugal are the ones facing most problems in verification of the parity used in this paper could help to explain the present instability in the Eurozone.

How long is the memory of the US stock market?

The Efficient Market Hypothesis (EMH), one of the most important hypothesis in financial economics, argues that return rates have no memory (correlation) which implies that agents cannot make abnormal profits in financial markets, due to the possibility of arbitrage operations. With return rates for the US stock market, we corroborate the fact that with a linear approach, return rates do not show evidence of correlation. However, linear approaches might not be complete or global, since return rates could suffer from nonlinearities. Using detrended cross-correlation analysis and its correlation coefficient, a methodology which analyzes long-range behavior between series, we show that the long-range correlation of return rates only ends in the 149th lag, which corresponds to about seven months. Does this result undermine the EMH?

Entrepreneurship rates the fuzzy-set approach

A fuzzy-set qualitative comparative analysis is applied to determine the necessary and sufficient conditions for higher entrepreneur rates. Based on Global Entrepreneurship Monitor data, it is shown that the most relevant conditions are Media Attention to Entrepreneurship, as well as Perceived Capabilities and Perceived Opportunities. The non-existence of Fear of Failure is also an important factor in determining higher entrepreneurship rates. When the sample is split, this condition is more important for most developed countries. This can be viewed as relevant information for policymakers to better define their policies to promote entrepreneurship, which is a key to more sustainable growth in countries.

G7 Stock Markets: Who is The First to Defeat The DCCA Correlation?

Following the methodology of Ferreira and Dionísio (2016), the objective of this paper is to analyze the behavior stock markets in the G7 countries and find which of those countries is the first to reach levels of long-range correlations that are not significant. We carry out this analysis using detrended cross-correlation analysis and its correlation coefficient, to check for the existence of long-range dependence in time series. The existence of long-range dependence could be understood as a possibility of EMH violation. This analysis remains interesting because studies are not conclusive about the existence or not of long memory in stock return rates.

What are the conditions for good innovation results? A fuzzy-set approach for European Union

Innovation is one of the main concerns of European Union countries since the beginning of the century. Despite failing to reach their targets, innovation remains a priority because innovation enables countries to achieve better economic performance. This study analyzes the relation between the level of innovation and the economic effects and applies a fuzzy-set qualitative comparative analysis to study the relation between six conditions and two different outcomes. The data comes from the Union Innovation Scoreboard. The study finds that research systems, linkages and entrepreneurship, and intellectual assets are necessary conditions for the outcomes of a high level of innovation and positive economic effects. The main sufficient condition for both outcomes is a good research system.

A CONSTRUÇÃO DO SENTIMENTO TOPOFÍLICO: O ENFOQUE SOBRE O SUB-BAIRRO DE AMOVILA (VISTA-ALEGRE) _ MUNICÍPIO DO RIO DE JANEIRO

Esta pesquisa objetiva compreender os diferentes mecanismos de construção do sentimento topofílico no sub-bairro de Amovila, de acordo com o tempo de moradia de seus moradores.Para isso, se investigou os marcos materiais e as imaterialidades imanentes do sub-bairro de Amovila, o qual faz parte do bairro de Vista-Alegre. O termo topofilia é um neologismo criado por Yi-Fu Tuan e consiste no elo afetivo entre o indivíduo e o seu lugar, que pode ser uma infinidade de possibilidades, como um objeto, um cômodo de uma casa, uma cidade ou um bairro. A metodologia consistiu na análise e na comparação dos discursos dos moradores a partir de entrevistas exploratórias e semi-estruturadas.

EL RELLENO SANITARIO EN CORDEL DE MORA: UN ENFOQUE GEOGRÁFICO

La problemática de la disposición final de los desechos sólidos que se generan en la gran Área Metropolitana, se ha constituido en la década de los 90, en una bomba tanto de tipo ambiental como de tipo política que ha representado para el gobierno una situación de emergencia en cuanto a su solución.  Entre las alternativas para la ubicación de un “sitio ideal” para la operación de un relleno sanitario, el Gobierno propuso una finca localizada en Cordel del cantón de Mora.Se conjugan en este documento, un enfoque social y político que involucra diferentes estratos sociales y escalas espaciales que van desde la local a la regional, y un enfoque físico –ambiental que enfatiza  en el análisis de las condiciones específicas del sitio y de las posibles rutas de acceso.  Se concluye que la solución a la problemática debe involucrar la participación más amplia de posible de la ciudadanía y con total transparencia en todos los niveles de decisión tanto técnicos como políticos.  En cuanto a lo físico-ambiental se concluye que el sitio no ofrece las mejores condiciones para una obra de este tipo; a la vez se hace una propuesta de otro sitio, cercano al anterior, que podría tener mejores condiciones.
