We lay a ground for a simple comparison of positive and possible side (adverse) effects of zero interest rate policy (ZLB policy) on welfare. Using a standard New Keynesian dynamic stochastic general equilibrium model, we show that if one assumes that the ZLB policy has no side effects, then...

The aim of our article is to analyze the dynamics of housing prices in the secondary housing market in Warsaw from Q1 2006 to Q3 2013, taking into account the spatial relationship between prices. In the first part of this research we compare the geographically weighted regression with a linear...

The study considers a stochastic R&D process where the invented production technologies consist of a large number n of complementary components. The degree of complementarity is captured by the elasticity of substitution of the CES aggregator function. Drawing from the Central Limit Theorem and...

The development of the card payment system allows for lowering the costs of money emission and circulation and thereby leads to significant economic gains. Yet relatively small amount of research has been dedicated to the analysis of the determinants of these developments. Therefore, the aim of...

Following Nyman (2010), the paper provides an indicator of resource utilisation (RU) for the Polish economy based on survey and labour market data. The indicator is subsequently used to identify output gap. Using real-time dataset, we find that output gap constructed in this way is revised to a...

This paper empirically investigates the evolution and the sources of interest rate pass-through heterogeneity in the Eurozone for a sample of 11 euro area countries over the period 2003M1-2011M12. Considering two harmonized bank retail rates, we first estimate single equation error correction...

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, (iii) capital–labor ratios, or (iv) capital–output ratios....

We study the determinants of capital income inequality in a general equilibrium portfolio choice model with endogenous information acquisition. The key elements of the model are heterogeneity in investor sophistication and in asset riskiness. The model implies capital income inequality that...

In a number of countries a substantial proportion of mortgage loans is denominated in foreign currency. In this paper we demonstrate how their presence affects economic policy and agents’ welfare. To this end we construct a small open economy model with financial frictions where housing loans...

Since the creation of the euro area significant interest rate spreads have arisen between euro area countries, both for public and private debt. We check whether these spreads could be made to work towards the goal of providing more stability to the euro area. In particular we focus on reducing...
