Choice Simplification: A Theory of Mental Budgeting and Naive Diversification
Botond Kőszegi and Filip Matějka
Kőszegi and Matějka develop a new theory of how an agent with costly yet flexible attention makes basic multiproduct consumption decisions. They are the first to explain how a person creates mental budgets from fungible finances, to predict that products are grouped into mental budgets according to their substitutability, and to identify a connection between mental budgeting and naïve diversification.

Migrating Extremists
Christian Ochsner and Felix Roesel
Why should migration of extremists be controlled? How much harm can a few individuals cause? Ochsner and Roesel use Nazi migration in Austria after WWII and observe a higher support for the radical right even today in their destinations, thanks to family ties and the founding of local parties. This suggests that controlling migration is crucial to containing the spread of radicalism.

An Informational Theory of Privacy
Ole Jann and Christoph Schottmüller
Privacy, whether online or offline, is often seen as an inefficient information asymmetry. Jann and Schottmüller develop a theory that challenges this view by showing how individual privacy can enhance the welfare of society, improve information aggregation and prevent inefficient statistical discrimination. The authors apply the theory to online privacy, credit decisions and transparency in government.

Tax Reforms and Inter-temporal Shifting of Corporate Income
Jaroslav Bukovina, Tomáš Lichard, Ján Palguta and Branislav Žúdel
Corporate income tax rates and rules have significant implications for welfare, typically estimated using taxable income elasticity with respect to the marginal tax rate. Analyzing Slovak 2010-2018 corporate tax return data, the authors illustrate that elasticity can be greatly overestimated if inter-temporal shifting of income is ignored. Taking shifting into account, the elasticity drops between 21 to 49%. Read more

The Ramadan Effect in the Workplace
Paola Bertoli, Veronica Grembi and Judit Vall-Castello
Aiming to study the impact of Ramadan on work accidents, the authors analyze daily data from Spain from 2003 to 2016. Interestingly, they observe a decrease in injuries for Muslim workers, with no spillover effects on non-Muslims. A possible explanation is that many companies offer some accommodations of work conditions for Muslim workers, which would support the idea that policies coordinating religious practices with working schedules might be used to decrease health costs related to occupational injuries.

Sorting of Candidates: Evidence from 20,000 Electoral Ballots
Klára Svitáková and Michal Šoltés
Svitáková and Šoltés show that when voters select across ranked lists, political parties sort candidates on the ballots according to their public and intra-party value, measured by donations and party membership. The results provide strong evidence that political parties skew their representation based on a quid pro quo relationship with candidates, i.e. they favor candidates with higher intra-party value despite the fact that they tend to get fewer votes.

Essays on Asset Pricing
December 2019
Mykola Babiak
Babiak’s thesis investigates how investor expectations and macroeconomic uncertainty affect asset prices and the real economy in general equilibrium settings. The models studied deviate from traditional frameworks in various ways, but they all examine different aspects of the same question: How does incomplete agent information affect the decision-making of agents, and what are the resulting implications for financial markets?

Essays on Costly Information Acquisition in Economics
August 2020
Vladimír Novák
Novak investigates endogenous information acquisition problems and their implications. He explores the impact of risk-aversion on the sequential allocation of an 'informational' resource in the two-armed bandit problem. He applies the theory of rational inattention to explore how belief formation depends on the status quo and can lead to belief polarization. In his last essay he estimates the rational inattention DSGE models and compares them with established models. Read more

Experiments in Corruptibility
January 2020
Momotenko, Iryna
Momotenko investigates corruption, which remains one of the most serious obstacles to social and economic development. She explores and identifies a peer effect of corrupt behavior, then experimentally investigates the wage-corruption relationship and finds that higher wages have a negative impact on willingness to accept bribes, and that the effect of wages on the propensity to act on bribes is U-shaped. An explanation of this is offered in the last chapter as linked to self-perceived socio-economic status. Read more

COVID-19 related policy recommendations and research have remained among the priorities for the IDEA Think Tank. One of their latest contributions is an interactive application, ‘Theory of Probability for Life’, which enables anybody, without any need to understand statistics, to interpret the results of the COVID-19 tests. The app can also serve as a tool for high school students, introducing them to Bayesian statistics and the challenges of interpreting test results. Visit the app

The CERGE-EI Foundation Teaching Fellows Program ran its pedagogical training courses, usually held in Prague each August, totally online this year. This was particularly timely since the bulk of teaching in the next academic year will be conducted online and there are already a number of lessons learned since the lockdowns of spring 2020. The new academic year sees nearly 200 Teaching Fellows teaching at 80 universities in 22 countries.
