Empirical data show that firms tend to improve their ranking in the productivity distribution over time. A sticky-price model with firm-level productivity growth fits this data and predicts that the optimal long-run inflation rate is positive and between 1.5% and 2% per year. In contrast, the...

A popular interpretation of the Rational Expectations/Efficient Markets hypothesis states that, if the hypothesis holds, then market valuations must follow a random walk. This postulate has frequently been criticized on the basis of empirical evidence. Yet the assertion itself incurs what we...

The economies of Central and Eastern Europe are undergoing a period of rapid structural change. The general pattern confirms to the J-curve anticipated by several observers at the start of transition. This paper conceptualises the J-curve as the result of a combination of two factors. First,...

We implement capital in an endogenous separations New Keynesian matching model. In contrast to the vintage capital theory, we suggest a more general approach, such that workers have unrestricted access to a proportional share of the capital stock. We find that the introduction of capital...

The provision of credit has been shown to be eminent for macroeconomic activity.Recent research highlighted that optimism may play a role in the provision of credit through leverage cycles. A decomposition of corporate bond spreads allows the modelling of a propensity-to-lend through an excess...

Available evidence supports the view that growth is faster in more open economies. In order to analyze the implications of openness and growth on determinacy and learnability of worldwide rational expectations equilibria we develop a two-country New Keynesian model with growth. We analyze these...

The proposal involves the establishment of ?welfare accounts? for every person in a country. There are to be four accounts: a retirement account (covering pensions), an unemployment account (covering unemployment support), a human capital account (covering education and training), and a health...

Government provision of a financial safety net for financial institutions has been a key element of the policy response to the current crisis, with governments extending existing guarantees and introducing new ones. These measures have been helpful in avoiding a further accelerated loss of...

The Ramsey approach to optimal taxation and Ramsey tax rules have amassed substance in economic theory. However, they are often criticized on grounds of practicality, fairness, feasibility and some other aspects of designing actual tax policy. This paper presents a collection of these views; it...
