In this thesis we try to understand the impact of some macroeconomic features of developing economies, in particular the existence of a large informal sector, on the reaction of these economies to different shocks. In order to achieve this objective, we derive a simple New Keynesian Small Open...

Since 1991, inflation in Colombia was reduced from 25% on average to about 6% more recently. Although this performance is in line with a long run inflation target of 3%, some analysts ask whether the Central Bank should continue disinflating. In this paper we present a dynamic stochastic general...

In this article, we studied the relationship between macroeconomic factors and the observed corporate births for the Romanian economy through the Autoregressive Distributed Lags Model (ADL). We performed a time series analysis that uses monthly data for the period January 2008 – December 2013...

The current consensus in macroeconomics, or New Neoclassical Synthesis (NNS), is based on dynamically stochastic general equilibrium (DSGE) modelling with a RBC core to which nominal rigidities are added by way of imperfect competition. The strategy is to minimize the frictions that are required...

Euro area countries as a whole have experienced a marked downward trend over the 1980s. Over this period, the unemployment rate has increased and economic activity has been sluggish. Changes in the implicit inflation target, viewed as low frequency movements of inflation, might possibly explain...

In this paper, we investigate the effects of an anticipated future change in monetary policy regime in small open economies targeting either inflation or the exchange rate. The announcement of a future change in the monetary policy regime triggers an immediate change in the behavior of...

The great contraction of 2008 pushed the U.S. economy into a protracted liquidity trap (i.e., a long period with zero nominal interest rates and inflationary expectations below target). In addition, the recovery was jobless (i.e., output growth recovered but unemployment lingered). This paper...
