The monetary pillar and the great financial crisis

Since its inception, a most distinctive (and controversial) feature of the ECB monetary policy strategy has been its emphasis on money and monetary analysis, which constitute the basis of the so-called monetary pillar. The present paper examines the performance of the monetary pillar around the recent financial crisis episode, and discusses its prospects in light of the renewed emphasis on financial stability and the need for enhanced macro-prudential policies.

What explains the Great Moderation in the US? A structural analysis

This paper investigates what has caused output and inflation volatility to fall in the USusing a small scale structural model using Bayesian techniques and rolling samples. Thereare instabilities in the posterior of the parameters describing the private sector, the policyrule and the standard deviation of the shocks. Results are robust to the specification ofthe policy rule. Changes in the parameters describing the private sector are the largest,but those of the policy rule and the covariance matrix of the shocks explain the changes most.

On the sources of the Great Moderation

The remarkable decline in macroeconomic volatility experienced by the U.S. economy since the mid-80s (the so-called Great Moderation) has been accompanied by large changes in the patterns of comovements among output, hours and labor productivity. Those changes are reflected in both conditional and unconditional second moments as well as in the impulse responses to identified shocks. That evidencepoints to structural change, as opposed to just good luck, as an explanation for the Great Moderation. We use a simple macro model to suggest some of the immediate sources which are likely to be behindthe observed changes.

Do expectations matter? The Great Moderation revisited

We examine the role of expectations in the Great Moderation episode. We derive theoretical restrictions in a New-Keynesian model and test them using measures of expectations obtained from survey data, the Greenbook and bond markets. Expectations explain the dynamics of inflation and of interest rates but their importance is roughly unchanged over time. Systems with and without expectations display similar reduced form characteristics. Including or excluding expectations hardly changes the economic explanation of the Great Moderation. Results are robust to changes in the structure of the empirical model.

The great diversification and its undoing

We investigate the hypothesis that macroeconomic fluctuations are primitively theresults of many microeconomic shocks, and show that it has significant explanatorypower for the evolution of macroeconomic volatility. We define ?fundamental? volatilityas the volatility that would arise from an economy made entirely of idiosyncratic microeconomicshocks, occurring primitively at the level of sectors or firms. In its empiricalconstruction, motivated by a simple model, the sales share of different sectors vary overtime (in a way we directly measure), while the volatility of those sectors remains constant.We find that fundamental volatility accounts for the swings in macroeconomicvolatility in the US and the other major world economies in the past half century. Itaccounts for the ?great moderation? and its undoing. Controlling for our measure offundamental volatility, there is no break in output volatility. The initial great moderationis due to a decreasing share of manufacturing between 1975 and 1985. The recentrise of macroeconomic volatility is due to the increase of the size of the financial sector.We provide a model to think quantitatively about the large comovement generated byidiosyncratic shocks. As the origin of aggregate shocks can be traced to identifiablemicroeconomic shocks, we may better understand the origins of aggregate fluctuations.

Los Grandes olvidados: las personas mayores en el entorno rural = The Great Forgotten Issue: Older People in Rural Context

Ageing is a heterogeneous subject being been able to distinguish profiles in function of sex, age, economic situation, cultural levels, habitat, family structure, health, etc. The objectives of this article are to identify forms of life to age in the rural environment and to concretize intervention proposals to increase active and participatory ways of life. 7 in-depth interviews to experts, 21 to older people, 5 to professionals and two focal groups of professionals and significant social agents were performed to collect data. Results identify 4 styles of aging: an opportunity for the change; a natural phase of the life; a moment to compensate and; a moment of abandonment. Conclusions summarize intervention proposals to increase active and participatory ways of ageing in different contexts to help professionals responsible for the services of older people care
