We estimate the macroeconomic and distributional effects that a ban on fuel imports from Russia would have in Poland. We simulate the embargo as a hike in oil, gas and coal prices, and evaluate the macroeconomic effects with a dynamic general equilibrium model. We soft-link ...

The timing of the response of CO2 emissions to a carbon tax depends crucially on the timing of response of energy demand of changes in energy prices. In this paper, we investigate the path of changing energy demand from the moment of a change in ...

We study steady state and business cycle properties of a model with heterogeneous firms and on-the-job search in the spirit of Moscarini and Postel-Vinay (2012). We extend the setup by including capital in the production function and show how this change influences model properties. The ...

We study the steady-state effects of working capital channel on the distribution of wages and reallocation of workers across employers. We first show that in a simple Burdett-Mortensen on-the-job search model, working capital channel matter for wage offers distributions of firms and wage distribution of ...

The most important engines for the growth of aggregate health care expenditures (HCE) in last 50 years in OECD have been growth of income, technological progress in medicine and their interaction with institutional setting. The accelerating ageing is expected to additionally fuel the growth of ...

Environmental taxes are a crucial instrument aimed at reducing resource use through lower production losses, resource-leaner products and more resource-efficient production processes. In this paper we focus on material use and apply a multisector DSGE model to study two types of taxation: tax on material ...

The aim of the article is to quantify the role of time-to-death in shaping health care costs. By combining a detailed break-down of population-wide data on publicly financed health care expenditure with the population and mortality data we are able to estimate a flexible model ...

The aim of the article is to show the role of the drivers of health care costs increases with age. An innovative decomposition strategy has been proposed and applied to the population-wide data on health care expenditure in Poland. We have found that the health ...

In this paper we utilize an open economy DSGE model to analyse factors behind the Great Recession and its transmission into labour markets of selected Southern European countries. We introduce a number of shocks which form potential sources of macroeconomic disturbances, in particular: foreign demand, ...

We assess the macroeconomic impact on Polish economy of the diversified package of about 120 different GHG mitigation levers, which were identified in the bottom-up sectoral analysis. For this purpose, we constructed a large scale, multi-sector dynamic stochastic general equilibrium (DSGE) model of Polish economy. ...

This paper discusses conditions for aggregation of heterogeneous expectations in a new-keynesian economy. I show that aggregation result depends on the way agents form cross-expectations, i.e. expectations on other agents’ decision variables, and I determine a maximal class of cross-expectations operators that support aggregation. Interpretation ...
