This article deals with the phenomenon of repeated contracts, specifically the effect of trust in public contracts. Our main objective is to identify the factors that influence the concluding of repeated contracts and to verify whether repeated contracts lead to increases in prices. We use a complex dataset of public procurement of municipalities in the Czech Republic for the period of 2014-2017, which covers more than 4,000 public contracts. This range of data allows a larger number of variables to be applied, including specific independent variables concerning municipalities, such as the size of the municipality. The data allow us to study this subject by means of both a general model tested on all public contracts and a partial model applied to public works. The presented results of quantitative econometric models from the data obtained from the awards of public contracts in the municipalities of the Czech Republic show that the fact of whether it was a repeated contract or a contract performed by a new (unknown to a contracting authority) supplier affected the chance of winning a contract.

This paper presents a comparison of time delays in the awarding of public sector contracts in the Czech Republic and the United Kingdom. The problem of these time delays has not been adequately addressed in the academic literature. The authors analysed the factors impacting on time delays in each country. A significant portion of GDP, in all countries, is allocated via public procurement. This paper compares the length of procurement procedures in the Czech Republic and the UK and the reasons for delays. The authors highlight the absence of public policies on procurement in the Czech Republic. A basic prerequisite for improving the results of public procurement is for all actors in the process to be involved and committed: officials and politicians and the public. [ABSTRACT FROM AUTHOR]

The article deals with the econometric analysis on the influence of selected characteristics of public contracts with respect to the decision making of bidders on public contracts regarding submissions to initiate proceedings to review the actions of the contracting authority at the Office for Protection of Competition. Logistic regression was applied to data on public procurement between the years 2007 and 2014, which was combined with the administrative decisions of the Office for the Protection of Competition, in order to identify the factors that affect the likelihood that the competitors will be protected against the conduct of the contracting authority by the Office for the Protection of Competition. The article also takes into account the possible obstructive behaviour of candidates, particularly those submissions which were subsequently withdrawn or submissions whose deposits were not paid.
