The Great Lockdown: information, noise and macroeconomic fluctuations
(2021-01)This paper argues that noisy information about lockdown can cause undesired economic fluctuations. We construct a New Keynesian model with imperfect information about how long the lockdown would last. On the one hand, a ... -
Hardware and Software over the Course of Long-Run Growth: Theory and Evidence
(2023-09)Output is generated through purposefully initiated physical action. Production needs energy and information, provided by respective factors: hardware (“brawn”), including physical labor and physical capital, and software ... -
The Hardware-Software Model: A New Conceptual Framework of Production, R&D, and Growth with AI
(2019-02)The article proposes a new conceptual framework for capturing production, R&D, and economic growth in aggregative models which extend their horizon into the digital era. Two key factors of production are considered: hardware, ... -
Have European natural gas prices decoupled from crude oil prices? Evidence from TVP-VAR analysis
(2022-06)Unprecedented increases in European natural gas prices observed in late 2021 and early 2022 raise a question about the sources of these events. In this article we investigate this topic using a time-varying parameters ... -
How do firms respond to demand and supply shocks?
(2022-04-12)The study aims to identify the granular demand and productivity shocks, their properties, and the responses of the important firm-level variables to these shocks. We use comprehensive data from the Polish enterprise sector ... -
How regional business cycles diffuse across space and time : evidence from a Bayesian Markov switching panel of GDP and unemployment in Poland
(2023-01)We investigate the regional business cycles at NUTS-3 granularity in Poland (N=73) using two variables in parallel: GDP dynamics and unemployment. The model allows for both idiosyncratic business cycle fluctuations in a ... -
The impact of firms' expectations & adjustments on the productivity cost of illness
(2016-05)Sickness-related absenteeism hinders firms' productivity and reduces output, an effect referred to as indirect cost (IC) and often included when assessing the burden of an illness or cost-effectiveness of a treatment. The ... -
Inherit Money or Brains? The Role of Inheritance and Its Taxation in OLG Analysis
(2024-12)Motivated by ongoing debates about the effectiveness of inheritance taxation in reducing wealth concentration—especially in contexts marked by strong family ties and rising wealth accumulation—this study employs an overlapping ... -
Innovation and Competition with Imperfect Patent Protection
(2025-05)We employ a duopoly model with horizontal differentiation of a product to analyse impact of imperfect patent rights in the form of a patent thicket on market entry and outcomes in a market when a single unit of a good is ... -
Institutional determinants of export competitiveness among the EU countries: evidence from Bayesian model averaging
(2019-04)Although the impact of institutions has been broadly studied in the literature on economic growth, their impact on international trade is less well-established. We aim to fill this gap by creating an extended database that, ... -
Intergenerational redistributive effects of monetary policy
(2021-03)This paper investigates the distributional consequences of monetary policy across generations. We use a life-cycle model with a rich asset structure as well as nominal and real rigidities calibrated to the euro area using ... -
Interim Correlated Rationalizability in Large Games
(2025-06)We provide general theoretical foundations for modeling strategic uncertainty in large distributional Bayesian games with general type spaces, using a version of interim correlated rationalizability. We then focus on the ... -
International confidence spillovers and business cycles in small open economies
(2020-05)The economic literature has for a long time been looking for explanations of a very strong international correlation of business cycles. This paper shows empirically that common fluctuations can to some degree be the effect ... -
International information flows, sentiments and cross-country business cycle fluctuations
(2020-03)Business cycles are strongly correlated between countries. One possible explanation (beyond traditional economic linkages like trade or finance) is that consumer or business sentiments spread over boarders and a ect cyclical ... -
Is panel Currency Demand equation homogeneous, why not, and what it means for shadow economy measurement
(2025-01)Currency Demand Analysis – one of the most popular macroeconometric techniques of shadow economy (SE) measurement – builds on equation explaining the share of cash in circulation in broader monetary aggregates, estimated ... -
Is Poland at risk of the zero lower bound?
(2016-07)In early 2015, the policy (open market operations) rate of Narodowy Bank Polski was reduced to an all-time low of 1.5%. At the same time, prices of consumer goods and services dropped by 1.5% in year-on-year terms. This ... -
Isoelastic Elasticity of Substitution Production Functions
(2016-01)We generalize the normalized Constant Elasticity of Substitution (CES) production function by allowing the elasticity of substitution to vary isoelastically with (i) relative factor shares, (ii) marginal rates of substitution, ... -
Iterative Monotone Comparative Statics
(2022-02)For an increasing upper order hemi-continuous correspondence F selfmapping sigma-complete lattice A, we first provide tight fixed-point bounds for sufficiently large iterations on F starting from any initial point a in A. ... -
Joint identification of monopoly and monopsony power
(2020-06)The article presents a generalization of an identification scheme of a monopolistic markup proposed by De Loecker and Warzynski (2012). We showed the relation between a price markup and factor wedges arising either due to ... -
Labor market institutions and the business cycle: The role of unemployment fears
(2023-12)We study the effects of labor market institutions (LMIs) in a general equilibrium model with search and matching frictions, endogenous separations, nominal rigidities, and uninsurable unemployment risk. By contrasting the ...
