Value creation in the international public procurement market: In search of springbok firms
2019
Abstract Public procurement accounts for more than 10% of global GDP. Digital transformation of public procurement creates new opportunities for value creation in international markets. Identifying and analyzing the companies, especially the SMEs, that can capitalize on these opportunities is therefore an important issue for policymaking, management, and scientific research. This study linked microdata on selected bidders from the Tenders Electronic Daily (TED) e-procurement portal and the Orbis database. Based on a sample of 933 Spanish companies, the analysis provides empirical support for the cross-border size bias conjecture. The reason for this bias is the predominance of large compani…
The Impact of the Direct Participation of Workers on the Rates of Absenteeism in the Spanish Labor Environment.
2020
The aim of this research was to study the relationship between the different levels of direct participation of workers (passive, consultative or active-delegated) in risk prevention management with the levels of absenteeism in Spain. To this end, a transversal study was carried out using microdata from the Second European Survey of Companies on New and Emerging Risks (ESENER-2-Spain, 2014) with a master population of 3162 work centres. A multinomial logistic regression model was carried out, with the dependent variable being the levels of absenteeism and the independent variables, the participation indicators and preventive management, calculating the adjusted odds ratio (aOR) between all t…
Aggregate Behavior and Microdata
2004
Abstract It is shown how one can effectively use microdata in modelling the change over time in an aggregate (e.g. mean consumption expenditure) of a large and heterogeneous population. The starting point of our aggregation analysis is a specification of explanatory variables on the micro-level. Typically, some of these explanatory variables are observable and others are unobservable. Based on certain hypotheses on the evolution over time of the joint distributions across the population of these explanatory variables we derive a decomposition of the change in the aggregate which allows a partial analysis: to isolate and to quantify the effect of a change in the observable explanatory variab…
