The non-stationarity of many macroeconomic time series has lead to an increased demand for economic models that are able to generate fragile equilibria. For instance, in this literature the natural unemployment rate is allowed to shift over time depending on past unemployment. Actually, many...

This paper examines the degree of persistence of regional relative unemployment. A theoretical model is built to explain the role of migration, labour-force participation, and real wage flexibility at the regional level, in determining such persistence. The model is used to account for the...

In this paper we use unit roots/cointegration analysis and time-varying parameters procedures to test for a common growth path in the ex-communist block, both pre- and post-reform. We test whether there has been convergence within the block and between the block as a group and the West....

Per capita incomes across European regions are not equal and do not stay constant; regional income distributions fluctuate over time. Such a process could have many possible limiting outcomes: complete equality (convergence), stratification, and continually increasing inequality are but three...

Cross-section or short-panel econometric techniques typically used to examine Gibrat’s Law of Proportionate Effect suggest that some degree of mean reversion exists, but may exaggerate the apparent randomness of corporate growth. We argue that a more natural way to explore the long-run...

This paper documents some stylized facts on evolving UK Phillips curves, and shows how these differ from their US versions. We interpret UK Phillips curve dynamics in a positive theory of monetary policy - how policy-maker attitudes on the Phillips curve have evolved since the 1950s - rather...

This Paper reviews recent econometric work on factor models in large cross-sections of time series. In this literature, traditional factor analysis is adapted to develop parsimonious estimation methods for high dimension time series models. The review covers problems of consistency and rates –...

Barter in Russia can be explained by firms' liquidity constraint: it is strongly correlated with financial tightness. However, a microeconomic analysis reveals that the rationale behind this liquidity constraint is different according to the firm situation. For firms in a good economic...
