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 ... -
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 ... -
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 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 ... -
Learning own preferences through consumption
(2022-04)This paper provides theoretical foundations for preference discovery theory. We propose to relax the assumption that the consumer has perfect knowledge of their own preferences, so that the consumer knows only the subjective ... -
Learning, experimentation and the convergence of the discovered preferences
(2024-03)In this article I study whether the interim preferences of the consumer can be expected to converge to their real preferences in the process of preference discovery. I construct a subjective expected utility model of the ... -
Lindhal meets Condorcet?
(2024-09)Although a Condorcet winner commands a majority in its favor, there is no guarantee of unanimity. In a Lindahl equilibrium, a suitably chosen system of personalized transfers and prices ensures unanimity, but there is no ... -
Local versions of Tarski’s theorem for correspondences
(2023-03)For a strong set order increasing (resp., strongly monotone) upper order hemicontinuous correspondence mapping a complete lattice A into itself (resp., a sigma-complete lattice into itself), we provide conditions for tight ... -
Macroeconomic Effects of Quantitative Easing Using Mid-sized Bayesian Vector Autoregressions
(2021-10)The paper estimates macroeconomic effects and decomposes transmission channels of quantitative easing in the United States using 15-variable Bayesian vector autoregressive model with stochastic search variable selection ...
