The risks of reforming doctoral studies
Grosman, Jiří ; Jurajda, Štěpán ; Münich, Daniel
The system of financing doctoral studies in the Czech Republic has long been inefficient. A reform currently underway aims to significantly increase the efficiency of the system. In this short text, we draw attention to potential problems associated with the distribution of public financial support for doctoral studies among universities. It would be problematic to distribute support based predominantly on degree completion rates. Allocation of public support for doctoral studies should take into account the results of evaluations of the quality of science produced by universities and their success in career placement of graduates, in addition to justifiable national disciplinary priorities.

Pupils’ (dis)interest in the teaching profession: an international comparison
Federičová, Miroslava
Many European countries, including the Czech Republic, currently face a shortage of teachers, especially quality teachers. One possible solution to this would be to support aspiring teachers at a younger age, during their studies at primary and secondary school. This study provides an empirical overview of teaching aspirations among 15-year-old school pupils in European countries based on data from the international PISA survey.

Analysis of the 2024 state budget revenue in light of the 2019 pre-crisis year
Janský, Petr ; Kolář, Daniel
This analysis compares planned state budget revenues in 2024 with the state budget outcomes of 2019. It charts a period in which the Czech economy and public budgets have been heavily impacted by the consequences of several major crises (coronavirus, the invasion of Ukraine and the war, an energy crisis, and an inflationary wave) as well as by significant parametric changes in the Czech tax system. 2019 can be considered the last pre-crisis year and 2024 the first post-crisis year, so they correspond to 'normal times' more closely than the years in between. This analysis builds on a previous analysis of the state budget expenditure development between 2019 and 2024 and includes a brief synthesis of findings on revenues and expenditures.

COVID-19 and political preferences through stages of the pandemic: the case of the Czech Republic
Bičáková, Alena ; Jurajda, Štěpán
We track the effects of the COVID-19 pandemic on political preferences through ‘high’ and ‘low’ phases of the pandemic. We ask about the effects of the health and the economic costs of the pandemic measured at both personal and municipality levels. Consistent with the literature, we estimate effects suggestive of political accountability of leaders during ‘high’ pandemic phases. However, we also find that the pandemic political accountability effects are mostly short-lived, and do not extend to the first post-pandemic elections.

Disappearing stepping stones: technological change and career paths
Kashkarov, Daniil ; Artemev, V.
Which career paths lead workers towards high-skilled non-routine cognitive occupations? Using PSID data, we show that, for a significant share of workers, a career path towards non-routine cognitive occupations goes through middle-skilled routine occupations, with the majority going through a subset of routine cognitive occupations. We then argue that the decline in employment in routine cognitive occupations due to routine-biased technological change can negatively affect the chances of younger cohorts joining high-skilled occupations. To test this hypothesis, we develop a structural occupational choice model that endogenously generates realistic career paths and estimate it using PSID data and job ad data from three major US outlets covering the period from 1940 to 2000. Our estimations suggest that, on average, 6% of workers ending up in non-routine cognitive occupations use routine cognitive occupations as stepping stones that allow them to maintain and accumulate human capital and experience relevant for later employment in high-skilled occupations. A fall in employment opportunities in routine cognitive occupations over the period of the most intensive routine-biased technological change led to at least 1.37 million lost high-skilled workers who got stuck in less skilled occupations.

Matching to suppliers in the production network: an empirical framework
Alfaro-Ureña, A. ; Zacchia, Paolo
This paper develops a framework for the empirical analysis of the determinants of input supplier choice on the extensive margin using firm-to-firm transaction data. Building on a theoretical model of production network formation, we characterize the assumptions that enable a transformation of the multinomial logit likelihood function from which the seller fixed effects, which encode the seller marginal costs, vanish. This transformation conditions, for each subnetwork restricted to one supplier industry, on the out-degree of sellers (a sufficient statistic for the seller fixed effect) and the in-degree of buyers (which is pinned down by technology and by “make-or-buy” decisions). This approach delivers a consistent estimator for the effect of dyadic explanatory variables, which in our model are interpreted as matching frictions, on the supplier choice probability. The estimator is easy to implement and in Monte Carlo simulations it outperforms alternatives based on group fixed effects. In an empirical application about the effect of a major Costa Rican infrastructural project on firm-to-firm connections, our approach yields estimates typically much smaller in magnitude than those from naive multinomial logit.

The American origin of the French Revolution
Ottinger, Sebastian ; Rosenberger, L.
We show that the French combatants’ exposure to the United States increased support for the French Revolution a decade later. French regions from which more American combatants originated had more revolts against feudal institutions, revolutionary societies, volunteers for the revolutionary army, and emigrants from the Old Regime’s elite. To establish causality, we exploit two historical coincidences: i) originally, a French army of seven and a half thousand was ready to sail, but one-third did not, ii) among those deployed, only some regiments were stationed in New England. Only combatants exposed to New England affected the French Revolution after their return.

Numerické optimalizační metody
Lukšan, Ladislav
Tato zpráva popisuje teoretické i praktické vlastnosti numerických metod pro nepodmíněnou optimalizaci. Studují se metody pro obecné i speciální optimalizační úlohy, mezi které patří minimalizace součtu čtverců, součtu absolutních hodnot, maximní hodnoty a dalších nehladkých funkcí. Kromě metod pro standardní úlohy středních rozměrů jsou studovány i metody pro rozsáhlé řídké a strukturované úlohy. Velká pozornost je věnována soustavám nelineárních rovnic.\n
