Material flows, efficiency and decoupling: Latvia's case study
2019
Latvia with its growing economy and intensive use of biomass is one of the biggest per capita natural resource consumers in Europe. If current patterns of resource use are maintained, environmental degradation and depletion of natural resources will continue. This paper looks at the resource flows in Latvia (1995 to 2016) - the country that does not have fossil energy resource deposits and timber industry is an important economic sector contributing most to the direct material input. It analyses the main resource flows, its intensities and looks at the main drivers behind these changes. Results demonstrate that resource extraction and consumption is steadily increasing and are not decoupled…
A Research Project about Communism in Romanian Countryside: Ploughmen’s Front Propaganda (1944-1953)
2013
The Ploughmen Front represented the strongest and the oldest “comrade” of the Communist Party from Romania, with a major role in the countryside communization. In general, the studies dedicated to Romania communization focused on institutionalization of the regime, liquidation of democratic order, repression, anticommunist resistance and less on the transformations undergone by the Romanian countryside. The only important issue was the agriculture collectivization. Our project takes into consideration a new approach, which is the research of the way communism became popular in the rural areas, which meant 80% of the Romanian population, how the popularity of the historical parties was dislo…
A Side-by-Side Single Sex Age-Structured Human Population Dynamic Model: Exact Solution and Model Validation
2008
A side-by-side single sex age-structured population dynamic model is presented in this paper. The model consists of two coupled von Foerster-McKendrick-type quasi-linear partial differential equations, two initial conditions, and two boundary conditions. The state variables of the model are male and female population densities. The solutions of these partial differential equations provide explicit time and age dependence of the variables. The initial conditions define the male and female population densities at the initial time, while the boundary conditions compute the male and female births at zero-age by using fertility rates. The assumptions of the nontime-dependence of the death and fe…
A New Multinomial Accuracy Measure for Polling Bias
2014
In this article, we propose a polling accuracy measure for multi-party elections based on a generalization of Martin, Traugott, and Kennedy's two-party predictive accuracy index. Treating polls as random samples of a voting population, we first estimate an intercept only multinomial logit model to provide proportionate odds measures of each party's share of the vote, and thereby both unweighted and weighted averages of these values as a summary index for poll accuracy. We then propose measures for significance testing, and run a series of simulations to assess possible bias from the resulting folded normal distribution across different sample sizes, finding that bias is small even for polls…
Disparités géographiques et convergence des régions européennes : une approche par l'économétrie spatiale
2002
The aim of this dissertation is to analyze the convergence process between European regions by taking into account spatial patterns of economic activities. First, with the help of literature reviews on theoretical and empirical analyses of growth and convergence and on economic geography models, we show in chapter 1 why geographic disparities should be introduced in the study of convergence between economies. Next, the spatial statistic and econometric tools allowing to reach this goal are detailed in chapter 2. Finally, three empirical studies of the convergence process in presence of geographic disparities are carried out. They are based on a sample for per capita GDP of 138 regions, belo…

Future wood demands and ecosystem services trade-offs: A policy analysis in Norway
2023
To mitigate climate change, several European countries have launched policies to promote the development of a renewable resource-based bioeconomy. These bioeconomy strategies plan to use renewable biological resources, which will increase timber and biomass demands and will potentially conflict with multiple other ecosystem services provided by forests. In addition, these forest ecosystem services (FES) are also influenced by other, different, policy strategies, causing a potential mismatch in proposed management solutions for achieving the different policy goals. We evaluated how Norwegian forests can meet the projected wood and biomass demands from the international market for achieving m…
On the Substitutability between Paid-employment and Self-employment: Evidence from the Period 1969–2014 in the United States
2019
This paper provides estimates of the elasticity of substitution between operational and managerial jobs in the US economy during the years 1969–2014, derived from an aggregate CES production function. Estimating the long-term relationship between (the log of) the aggregate employment/self-employment ratio and (the log of) the returns from paid-employment relative to self-employment and testing for structural breaks, we report different estimates of the elasticity of substitution in each of the two regimes identified. To this end we apply the methodology on instability tests proposed in Kejriwal and Perron (2008, 2010) as well as the cointegration tests developed in Arai and Kurozumi (2007) …
Does better education mitigate risky health behavior? A mendelian randomization study.
2022
Education and risky health behaviors are strongly negatively correlated. Education may affect health behaviors by enabling healthier choices through higher disposable income, increasing information about the harmful effects of risky health behaviors, or altering time preferences. Alternatively, the observed negative correlation may stem from reverse causality or unobserved confounders. Based on the data from the Cardiovascular Risk in Young Finns Study linked to register-based information on educational attainment and family background, this paper identifies the causal effect of education on risky health behaviors. To examine causal effects, we used a genetic score as an instrument for year…
La inserción de las personas con discapacidad en el empleo público. Análisis jurídicoeconómico de la situación en la Comunidad de Madrid
2018
Las personas con discapacidad sufren dificultades de acceso al mercado de trabajo que exigen políticas públicas de protección y mecanismos específicos que favorezcan la inserción laboral. Este trabajo se centra en los instrumentos de acceso al empleo en el sector público, sus principios, características (distintas de las del sector privado), así como los problemas que plantea para las personas con discapacidad.
 En España, la normativa -básica estatal y desarrollo normativo autonómico- es poco ambiciosa y prácticamente limita las medidas positivas al cupo de reserva, consistente en que un porcentaje de las plazas convocadas se reservan a personas con discapacidad. Los conflictos judici…
