Le sourire énigmatique de la vie
2013
On pourrait espérer que, plus que n’importe quelle autre, les philosophies qui se sont vues dénommées ou se sont elles-mêmes intitulées « philosophie de la vie » nous éclairent sur ce qu’il faut entendre par ce terme de « vie ». Sauf que l’unité d’une telle philosophie est problématique au regard de la diversité des figures qui l’incarnent. Sans remonter à l’époque où elle émerge, par exemple dans la pensée de Herder, puis se prolonger dans le romantisme, la vie est comme l’avance Herbert Sch...

Convergence of prices on the pig market in selected European Union countries. Case study
2022
Due to its specificity, animal production depends to a lesser extent than plant production on agrometeorological conditions. Interdependence between the prices of animal products and climatic conditions manifests itself primarily through the fodder markets, which determine the profitability of animal breeding and keeping. The process of economic integration should contribute to a decline in price differentiation between European Union (EU) countries. In the case of the pig market, however, it is necessary to bear in mind the pig cycle, which particularly affects the supply of livestock and their prices. The Common Agricultural Policy (CAP) currently implemented is not adapted to the turbule…
Climate and agriculture: empirical evidence for countries and agroecological zones of the Sahel
2022
International audience; ow heterogenous is the impact of climate change across space and the type of agricultural production? In this paper, we investigate the relationship between climate change and variability, measured by temperature and rainfall, and agricultural production at the country and agroecological zone levels of the Sahel. We consider a crop production index and five cereals (maize, millet, sorghum, wheat and rice). Based on an original climate database and an agricultural production function estimated for the period 1961–2016, we show that average rainfall and temperature during the growing season indeed have highly heterogeneous effects on agricultural production, depending …
A Bayesian Reconstruction of a Historical Population in Finland, 1647–1850
2020
This article provides a novel method for estimating historical population development. We review the previous literature on historical population time-series estimates and propose a general outline to address the well-known methodological problems. We use a Bayesian hierarchical time-series model that allows us to integrate the parish-level data set and prior population information in a coherent manner. The procedure provides us with model-based posterior intervals for the final population estimates. We demonstrate its applicability by estimating the long-term development of Finlands population from 1647 onward and simultaneously place the country among the very few to have an annual popula…
Forecasting Passenger Traffic for a Regional Airport
2019
Abstract The purpose of the present research is estimating the potential traffic for SIA (Sibiu International Airport, SBZ) for the year 2017. Predicting as accurate as possible the passenger traffic for a certain airport is an aspect of major importance for both the airport management and the airline companies. The theoretical quality of the forecasting models for air traffic of passengers is fundamental for obtaining the most accurate predictions. In this regard, a two-step process was used in developing the traffic forecasting model: (1) Identifying the proper regression model for traffic estimation based on the number of aircraft departures, and (2) Forecasting the number of aircraft de…
Air Transportation and Regional Growth: Which Way Does the Causality Run?
2013
The role of airports has become increasingly important with globalization. To have a regional airport is an especially important asset for retaining companies in the region as well as attracting new economic activity to the region. A well-developed transport infrastructure can be seen as a facilitator that allows the economic potential of a region to be realized. The provision of transportation does not, however, automatically lead to economic growth. It may also be the other way round: economic development leads to the better transport infrastructure and accessibility, stressing demand side elements. This paper aims to shed further light on the relationship between regional airports and ec…
Management Practices and Allocation of Employment: Evidence from Finnish Manufacturing
2020
We analyse variation in the management practices across countries and across regions within a country. For cross-country comparisons we use the Finnish Management and Organizational Practices Survey (FMOP) to calculate a management score for Finnish manufacturing that is compared to corresponding measures obtained from similar data in the US and Germany. Scores measured by unweighted averages of the establishments in these countries show that Finland is only slightly behind the US and on par with those of Germany. With the FMOP data, we then perform an Olley-Pakes decomposition of the management score using a moment-based estimation procedure. Our decomposition shows no statistically signif…
The effectiveness of the autoregressive models in forecasting the agricultural prices in Poland
2010
The forecast of agricultural prices is one of the most important factors in making decision on production farms. The appropriate forecast allows for limiting the risk connected with one’s economic activity. In this study autoregressive models have been used, which helped to determine the price forecast for agricultural products in the purchasing centers in the second half of 2010. To determine the quality of forecast the average ex-post errors of the past forecasts have been used. The achieved results show that autoregressive models are an effective tool in forecasting the agricultural prices in Poland.
