We analyze the behaviour of prices in Uruguay using a unique database of 30 millions daily prices. We find that prices change about 5 times a year with no seasonal patter. Prices changes are highly synchronised and concentrated on the first day of the month. Our paper is the first to present...

This paper resolves the sectoral comovement problem between nondurable and durable outputs that arises in response to a monetary shock in a two-sector sticky price model with flexibly priced durable goods. We analytically demonstrate that the non-separability between aggregate consumption and...

In this paper, by utilizing the Poincaré–Bendixson theory and the Hopf bifurcation theory, we analyze both rigid-price and flexible-price nonlinear disequilibrium Keynesian macroeconomic systems, prove the existence of a persistent business cycle and derive the conditions for global...

Jim Tobin, who died on March 11, 2002 at the age of 84, was one of giants of economics of the second half of the twentieth century and the greatest macroeconomist of his generation. Tobin’s influence on macroeconomic theory is so pervasive - so much part of our professional ‘acquis’ - that...

La crise mondiale et celle, plus récente, dans la zone euro ont eu tendance à raccourcir l’horizon prévisionnel et décisionnel de nombreux agents économiques. Dans le même temps, les incertitudes (sur l’emploi, les retraites…) poussent plutôt à la remontée du taux d’épargne des...

We develop a Heterogeneous Agent New Keynesian model with a three-state frictional labour market that is consistent with the empirical evidence that (i) low-skilled workers are more exposed to the business cycle, (ii) displacement leads to long-lasting earnings losses, and (iii) unemployment is...

The main purpose of this article is to briefly present the Keynesian explanation of business cycle, economic fluctuation and crises, and also the solutions proposed from Keynesian perspective to the economic problems that characterize the bust phases of the business cycles (unemployment,...

Using panel data for the Euro Area countries in the period since 1972 this paper explores, in the context of a small model of the E.U. economy, the degree to which macroeconomic policy has been asymmetric. It shows in particular that monetary policy has been much more responsive to threats that...

This paper shows that there are striking implications that stem from including durable goods in otherwise conventional sticky price models. The behavior of these models depends heavily on whether durable goods are present and whether these goods have sticky prices. If long-lived durables have...
