Naked exclusion with heterogeneous buyers
Chen, Y.; Zápal, Jan
2022 - English
We investigate the effects of buyer heterogeneity in a market in which an incumbent firm prevents entry when it signs enough exclusionary contracts with buyers. With heterogeneous buyers several well-known results in exclusionary contracting with homogenous buyers are overturned and novel ones emerge. First, inefficient equilibria exist in which exclusionary contracts are signed but entry still occurs, and the loss of consumer surplus falls on small buyers. Second, sequential contracting may be more pro-competitive than simultaneous contracting in the sense that entry occurs under sequential but not simultaneous contracting. When this happens, sequential Pareto dominates simultaneous contracting.

Diffusion Kalman filtering under unknown process and measurement noise covariance matrices
Vlk, T.; Dedecius, Kamil
2022 - English
The state-of-the-art algorithms for Kalman filtering in agent networks with information diffusion impose the requirement of well-defined state-space models. In particular, they assume that both the process and measurement noise covariance matrices are known and properly set. This is a relatively strong assumption in the signal processing domain. By design, the Kalman filters are rather sensitive to its violation, which may potentially lead to their divergence. In this paper, we propose a novel distributed filtering algorithm with increased robustness under unknown process and measurement noise covariance matrices. It is formulated as a Bayesian variational message passing procedure for simultaneous analytically tractable inference of states and measurement noise covariance matrices.

Who divorces whom: unilateral divorce legislation and the educational structure of marriage
Afunts, Geghetsik; Jurajda, Štěpán
2022 - English
There is evidence that the introduction of unilateral divorce legislation (UDL) starting in the late 1960s increased US divorce rates. We ask whether making divorce easier affected the educational structure of marriage. Based on marriage and divorce certificate data covering 1970-1988, we provide new evidence on the evolution of the educational structure of marriage inflows (newlyweds) and outflows (divorces), and estimate UDL difference-in-differences effects on both flows. While UDL did not contribute to rising homogamy (the tendency towards married partners having the same level of education), it did affect the educational structure of marriage: it made generally unstable hypogamous couples (women marrying less educated partners) less likely to divorce, and it made homogamous couples more stable than hypergamous ones (women marrying more educated partners).

Recursive mixture estimation with univariate multimodal Poisson variable
Uglickich, Evženie; Nagy, Ivan
2022 - English
Analysis of count variables described by the Poisson distribution is required in many application fields. Examples of the count variables observed per a time unit can be, e.g., number of customers, passengers, road accidents, Internet traffic packet arrivals, bankruptcies, virus attacks, etc. If the behavior of such a variable exhibits a multimodal character, the problem of clustering and classification of incoming count data arises. This issue can touch, for instance, detecting clusters of the different behavior of drivers in traffic flow analysis as well as cyclists or pedestrians. This work focuses on the model-based clustering of Poisson-distributed count data with the help of the recursive Bayesian estimation of the mixture of Poisson components. The aim of the work is to explain the methodology in details with an illustrative simple example, so that the work is limited to the univariate case and static pointer.

Inattentive price discovery in ETFs
Kosar, Mariia; Mikhalishchev, Sergei
2022 - English
This paper studies the information choice of exchange-traded funds (ETF) investors, and its impact on the price efficiency of underlying stocks. First, we show that the learning of stock-specific information can occur at the ETF level. Our results suggest that ETF investors respond endogenously to changes in the fundamental value of underlying stocks, in line with the rational inattention theory. Second, we provide evidence that ETFs facilitate propagation of idiosyncratic shocks across its constituents.

Optimally biased expertise
Ilinov, Pavel; Matveenko, A.; Senkov, Maxim; Starkov, E.
2022 - English
This paper shows that the principal can strictly benefit from delegating a decision to an agent whose opinion differs from that of the principal. We consider a “delegated expertise” problem in which the agent has an advantage in information acquisition relative to the principal, as opposed to having preexisting private information. When the principal is ex ante predisposed towards some action, it is optimal for her to hire an agent who is predisposed towards the same action, but to a smaller extent, since such an agent would acquire more information, which outweighs the bias stemming from misalignment. We show that belief misalignment between an agent and a principal is a viable instrument in delegation, performing on par with contracting and communication in a class of problems. Keywords: delegation; rational inattention; heterogeneous beliefs Fulltext is available at external website.

Consequences of inconvenient information: evidence from sentencing disparities
Šoltés, Michal
2022 - English
Inconvenient information about the performance of public institutions may undermine public trust. In an experiment, I test how information about sentencing disparities among judges in the Czech Republic affects respondents’ perception of the judicial system. I find no effect on respondents’ declared institutional trust and willingness to rely on the formal judicial system. Instead, the information marginally increased respondents’ policy involvement: They became more likely to: (i) sign a petition that invites politicians to address the underlying issue, and (ii) consider fairness of the judicial system a more important policy issue. The increased interest in the petition was driven by mothers, who are arguably more sensitive to the particular treatment information in the presented case of a failure to pay alimony.

Compliance behavior under surveillance: introduction of the video assistant referee to European football
Trestcov, Ivan
2022 - English
This paper analyzes the effect of introducing the Video Assistant Referee (VAR) to European football. First, the setting allows for decomposition of the deterrence and monitoring effects in Becker’s (1968) model of crime. Second, I estimate the deterrence effect’s spillover outside the surveillance environment. Third, I find evidence of a much under-studied learning-by-punishment effect. This paper applies the difference-in-difference strategy to show that the introduction of VAR causes a significant decrease in the number of fouls in two German football leagues. VAR had an immediate impact on severe fouls, while the effect on penalty fouls is apparent after a 12 week adjustment period. Punishment intensifies the deterrence effect as punished players commit even fewer fouls than unpunished players. Moreover, the deterrence effect persists outside of the surveillance environment, i.e., there is a spillover effect on international competitions. I show that players from countries with VAR commit fewer fouls in international competitions than other players. Keywords: Becker model; video assistant referee; deterrence Fulltext is available at external website.

Macroeconomic Responses of Emerging Market Economies to Oil Price Shocks: Analysis by Region and Resource Profile
Togonidze, S.; Kočenda, Evžen
2022 - English
This study employs a vector autoregressive (VAR) model to analyse how oil price shocks affect macroeconomic fundamentals in emerging economies. Findings from existing literature remain inconclusive how macroeconomic variables fare towards shocks, especially in emerging economies. The objective of our study is to uncover if analysis by region (Latin America and the Caribbean, East Asia and the Pacific, Europe, and Central Asia) and resource intensity of economies (oil exporters, oil importers, minerals exporters, and less resource intensive). Our unique approach forms part of our contribution to the literature. We find that Latin America and the Caribbean are least affected by oil price shocks, while in East Asia and the Pacific the response of inflation and interest rate to oil price shocks is positive, and output growth is negative. Our analysis by resource endowment fails to show oil price shocks’ ability to explain huge variations in macroeconomic variables in oil importing economies. Further sensitivity analysis using US interest rates as an alternative source of external shocks to emerging economies establishes a significant response of interest rate responses to US interest rate in Europe and Central Asia, and in inflation in Latin America and the Caribbean. We also find that regardless of resource endowment, the response of output growth and capital to a positive US interest rate shock is negative and significant in EMs. Our results are persuasive that resource intensity and regional factors impact the responsiveness of emerging economies to oil price shocks, thus laying a basis for policy debate.\n Keywords: Emerging market economies; Oil shocks; GDP; Markov-switching; Exchange rate; Oil exporters; Metal exporters Fulltext is available at external website.

Yield Curve Dynamics and Fiscal Policy Shocks
Kučera, A.; Kočenda, Evžen; Maršál, Aleš
2022 - English
We show that government spending does play a role in shaping the yield curve which has important consequences for the cost of private and government financing. We combine government spending shock identification strategies from the fiscal macro literature with recent advancements in no-arbitrage affine term structure modeling, where we account for time-varying macroeconomic trends in inflation and the equilibrium real interest rate. We stress in our empirical macro-finance framework the importance of timing in the response of yields to government spending. We find that the yield curve responds positively but mildly to a surprise in government spending shocks where the rise in risk-neutral yields is compensated by a drop in nominal term premia. The news shock in expectations about future expenditures decreases yields across all maturities. Complementarily, we also analyze the effect of fiscal policy uncertainty where higher fiscal uncertainty lowers yields. Keywords: Government Expenditures; Fiscal policy; U.S. Treasury Yield Curve; Affine Term Structure Model Fulltext is available at external website.
