Productivity analysis of Latvian companies using ORBIS database

2021

International audience; This research study uses ORBIS microdata at the company level to analyse productivity of 167 thousand economically active Latvian companies over 2011-2018. The aim of the study is twofold-to find factors consistently associated with productivity at the company level; and to recommend possible criteria for companies to receive a state support (from the view of enhancing aggregate productivity in the long term). Our research results show that productivity of Latvian companies is positively related to their size, age, as well as location closer to Riga and other big cities. However, there is a substantial within-group variation in productivity between companies. Multiva…

NEIGHBORHOOD EFFECTS IN SPATIAL HOUSING VALUE MODELS. THE CASE OF THE METROPOLITAN AREA OF PARIS (1999)

2009

In hedonic housing models, the spatial dimension of housing values are traditionally processed by the impact of neighborhood variables and accessibility variables. In this paper we show that spatial effects might remain once neighborhood effects and accessibility have been controlled for. We notably stress on three sides of neighborhood effects: social capital, social status and social externalities and consider the accessibility to the primary economic center as describing the urban spatial trend. Using spatial econometrics specifications of the hedonic equation, we estimate whether spatial effects impact the housing values. Our empirical case concerns the Metropolitan Area (MA) of Paris i…

The role of informal learning in adults' literacy proficiency

2021

This study used the Programme for International Assessment of Adult Competencies (PIAAC) dataset to examine informal literacy learning’s effects on adults’ literacy proficiency. Also, the factors associated with informal literacy learning at and outside of work were studied. The study participants were Nordic adults aged 35–65 years. The statistical method was regression analysis, and the results indicate that informal literacy activities at work are associated primarily with occupation, and informal literacy activities outside of work with education, parents’ education and gender. Initial education, occupation, language background and age exerted the strongest estimated associations with r…

Forecasting correlated time series with exponential smoothing models

2011

Abstract This paper presents the Bayesian analysis of a general multivariate exponential smoothing model that allows us to forecast time series jointly, subject to correlated random disturbances. The general multivariate model, which can be formulated as a seemingly unrelated regression model, includes the previously studied homogeneous multivariate Holt-Winters’ model as a special case when all of the univariate series share a common structure. MCMC simulation techniques are required in order to approach the non-analytically tractable posterior distribution of the model parameters. The predictive distribution is then estimated using Monte Carlo integration. A Bayesian model selection crite…

Taking care of everyone’s business: interpreting Sicilian Mafia embedment through spatial network analysis

2022

Mafia-type organisations often have a strong geographical and cultural entrenchment in the territory they belong. However, their analysis as a spatially networked social structure is still missing. A combined socio-spatial network analysis is presented here, through the demise of a large police operation called Operazione Perseo in 2008. This approach is developed in two ways. At first, a visual representation of the social network of this large group of mafiosi embedded in a geographical space is presented. Three main salient territorial features of the network are thus highlighted. A high density of links in some neighbourhoods, as well as connections across different Mandamenti, the terr…

Global Divergence in Growth Regressions

2013

This paper extends the standard growth regression model by adding an assumption that a country follows the global technology frontier either fully or partially. This additional assumption changes significantly the growth regression model and its results in three main ways. First, it shows that although a country converges to its long-run growth path, this path can diverge from the countries at the global frontier. We measure the degree of divergence for each country and find that most indeed diverge from the frontier. Second, we estimate growth dynamics without controlling for additional variables. Third, our new method enables us to disentangle the effects of the explanatory variables on t…

Processing Information During Regressions: An Application of the Reverse Boundary-Change Paradigm.

2018

Although 10-15% of eye-movements during reading are regressions, we still know little about the information that is processed during regressive episodes. Here, we report an eye-movement study that uses what we call the "reverse boundary change technique" to examine the processing of lexical-semantic information during regressions, and to establish the role of this information during recovery from processing difficulty. In the critical condition of the experiment, an initially implausible sentence (e.g. "There was an old house that John had ridden when he was a boy.") was rendered plausible by changing a context word ("house") to a lexical neighbour ("horse") using a gaze-contingent display …

Interactions, spillovers de connaissance et croissance des économies modernes. Faut-il préférer la globalisation ou la proximité géographique ?

2009

Globalisation and metropolisation in modern economies induce some locational strategies of knowledge based activities towards cities and deeply increase trade and move of ideas across cities. In that context, we study the way knowledge spillovers have influenced the economic growth of 82 European Metropolises over the 1990-2005 period. We model knowledge spillovers across cities according to three specific interaction patterns depending either on geography or on global advanced services or thought a combination of these patterns. We show that the mixed pattern matters the best for economic growth of cities in Europe.

Materiālo un nemateriālo motivācijas rīku novērtējums Baltijas valstīs

2021

Šajā darbā tiek apskatītas klasiskās un mūsdienīgās motivācijas teorijas, kā arī tiek pētīti materiālie un nemateriālie motivācijas jēdzieni un to nozīme darbiniekiem. Mērķis tiek sasniegts, analizējot nepieciešamo literatūru, veicot pētījumus par šo tēmu un veicot pašu autoru pētījumus Baltijas valstīs. Lai analizētu aptaujas rezultātus, autors veic vairākas regresijas, izmantojot OLS metodi. Pirmajā nodaļā ir aplūkots motivācijas jēdziens, kā arī materiālie un nemateriālie motivācijas faktori. Otrajā nodaļā analizēti citu autoru secinājumi līdzīgā jomā, kā arī sniegti darba raksturojumi Baltijas valstīs. Trešajā nodaļā analizēti iegūtie rezultāti un salīdzināti ar iepriekš iegūtajām atziņ…
