- Abstract
- This paper examines the process of adjustment of prices in Italy to determine whether nominal flexibility, measured by the frequency of price changes, has increased in the recent years of protracted stagnation and double-dip recession. The analysis is based on a large micro-level dataset of individual prices collected monthly by Istat from 2006 to 2013 for the Consumer Price Index. We find that both the percentage of prices adjusted monthly and the average size of the adjustment have risen significantly since the 1996-2001 period, in particular for downward changes. This greater flexibility is related in part to the spread of modern distribution structures. Our estimates further indicate that the recession has affected the price adjustment mechanism: for manufactures, price cuts have become larger and more frequent, while increases are more moderate; for services, both the frequency and the size of price increases have diminished.

- Abstract
- This paper presents new evidence on the patterns of price and wage adjustment in European firms and on the extent of nominal rigidities. It uses a unique dataset collected through a firm-level survey conducted in a broad range of countries and covering various sectors. Several conclusions are drawn from this evidence. Firms adjust wages less frequently than prices: the former tend to remain unchanged for about 15 months on average, the latter for around 10 months. The degree of price rigidity varies substantially across sectors and depends strongly on economic features, such as the intensity of competition, the exposure to foreign markets and the share of labour costs in total cost. Instead, country specificities, mostly related to the labour market institutional setting, are more relevant in characterising the pattern of wage adjustment. The latter exhibits also a substantial degree of time-dependence, as firms tend to concentrate wage changes in a specific month, mostly January in the majority of countries. Wage and price changes feed into each other at the micro level and there is a relationship between wage and price rigidity.

- Abstract
- This study investigates the pricing behaviour of firms in the euro area on the basis of surveys conducted by nine Eurosystem national central banks, covering more than 11,000 firms. The results, robust across countries, show that firms operate in monopolistically competitive markets, where prices are mostly set following markup rules and where price discrimination is common. Around one-third of firms follow mainly time-dependent pricing rules while two thirds allow for elements of state-dependence. The majority of firms take into account past and expected economic developments in their pricing decisions. Price stickiness is mainly driven by customer relationships

- Abstract
- This paper investigates the behaviour of consumer prices in Italy by looking at micro data in the attempt to obtain a quantitative measure of the unconditional degree of price rigidity in the Italian economy. The analysis focuses on the monthly frequency of price changes and on the duration of price spells, also with reference to different types of products and outlets. Prices tend to remain unchanged on average for around 10 months; duration is longer for nonenergy industrial goods and services and much shorter for energy products. Price changes are more frequent upward than downward, in larger stores than in traditional ones. When the geographical location of outlets is accounted for, price changes display considerable synchronisation, in particular in the service sector.

- Abstract
- This study examines price setting behaviour of Italian firms on the basis of the results of a survey conducted by Banca d'Italia in early 2003 on a sample of around 350 firms belonging to all economic sectors. Prices are mostly fixed following standard mark-up rules, although customer-specific characteristics have a role, in particular in manufacturing and services where price discrimination across customers matters. Rival prices mostly affect pricesetting strategies in industrial firms. In reviewing their prices, firms follow either state-dependent rules or a combination of time and state-dependent ones. Concerning the frequency of price adjustments, a considerable degree of stickiness emerges both at the stage in which firms evaluate their pricing strategies and the stage in which they actually implement the price change. In 2002 most firms changed their price only once. Three alternative explanations of nominal rigidity are ranked highest by the firms interviewed: explicit contracts, tacit collusive behaviour and the perception of the temporary nature of the shock. Prices respond asymmetrically to shocks, depending on the direction of the adjustment (positive vs negative) and the source of the shock (demand vs supply). Real rigidities - captured by the degree of market competition, customers' search costs, the sensitivity of profits to changes in demand - play an important role in determining this asymmetry. Moreover, whereas cost shocks impact more when prices have to be raised than when they have to be reduced, demand decreases are more likely to induce a price change than demand increases.

- This paper examines the issue of the impact of aggregation in the empirical analysis of euro area labour markets. A Phillips Curve describing the adjustment of unit labour costs is estimated at the national and aggregate level for the 5 largest euro area countries. Potential sources of aggregation bias are investigated

- Abstract
- This paper addresses the issue of measuring the NAIRU for the euro area and assessing the robustness and precision of the obtained estimates. The empirical framework adopted is based on systems combining an Okun-type relationship between cyclical unemployment and the output gap with a Phillips curve and stochastic laws of motion for the NAIRU and potential output. Such systems have been estimated using Kalman-filter techniques. The aim of this approach is double: on the one hand, recent advances in the mentioned techniques are exploited, also with the aim of assessing the degree of uncertainty around the derived measures; on the other hand, the robustness of the approach is tested by looking at alternative versions of the systems themselves. The results obtained point to an estimate of the area-wide NAIRU that is robust to changes in the underlying models. This robustness is shown to hold both in terms of the mean - i.e., the shape of the resulting NAIRU - and the variance of the process. The latter is derived through bootstrap exercises using the models alone or pooled together. The evidence found suggests that the increase in the aggregate NAIRU that took place in the early part of the sample period has come to a halt and may be about to be reversed. The estimated final level for the NAIRU is around 10 per cent. Furthermore, the bootstrap exercises point to confidence bands close to 1 per cent around the estimated value.

- Abstract
- We derive indicators of labour market flexibility that are comparable across countries and time intervals. Our indicators build on a structural VAR model of real wages, output and unemployment dynamics. We compute our indicators for thirteen OECD countries and for two time periods, and we compare them with existing indicators of labour market flexibility in the literature . The main result of the paper is that we did not find evidence of a closing gap in terms of labour market flexibility between the United States and continental European countries, although our findings suggest that medium-sized and small countries have experienced greater improvements in this regard than the large countries since the mid-eighties.

- Abstract
- The paper attempts at disentangling the main sources of the rise in the Italian unemployment rate over the last four decades on the basis of a small model a la Layard-Nickell, identified and estimated using a structural VAR approach. Unemployment movements are assumed to be driven by fully permanent and long-lived but temporary shocks. The component of unemployment related to current and lagged demand shocks deriving from the sVAR estimation is found to be relevant and quite persistent, its swings accounting for approximately a 4 percentage points change in the unemployment rate. In particular, while temporary by construction, this component shows an almost continuous increase since the beginning of the 1980s. Nonetheless, the results confirm that the bulk of the rise in Italian unemployment is to be attributed to non-demand factors: temporary (namely productivity and labour supply shocks) and fully permanent (namely shocks to the wage bargaining schedule). The latter explain a gradual rise of about 2.5 percentage points between the end of the 1960s and the beginning of the 1980s; over the last 15-20 years, however, they do not seem to have further contributed to the worsening of unemployment situation.

- Abstract
- The paper focuses on the measurement of the NAIRU (Non-Accelerating-Inflation-Rate-of-Unemployment) for the euro area and assesses the usefulness of different methodologies developed in the literature to estimate this unobservable variable at the aggregate level. After reviewing the theoretical framework underlying the most common estimation approaches, it presents several estimates of the area-wide NAIRU based on a number of direct (or statistical) techniques. The latter range from simple univariate filtering approaches to more complex multivariate methods based on Phillips curve relationships. The different estimates of the aggregate NAIRU appear to be consistent and robust with respect to alternative specifications, methodologies and choice of the inflation indicator. They also show significant inflation forecasting ability and are able to produce sensible measures of the output gap, therefore providing some ground to argue that unemployment and the unemployment gap may be a useful variable to analyse short-term economic developments at the euro area level.
