Abstract
Using a macro–micro econometric framework that allows studying the labour market dynamics, this paper offers an in-depth investigation of the structures of both national and macro regional labour markets in Italy. The simulation results reveal structural differences between regions in the short as well as the long run. Regional gaps represent one of the main components of the natural unemployment rate in Italy. The results may help regional and national policy makers in the European Union to formulate strategies tailored to the specific needs of regional labour markets.

Notes
According to the standard classification and on the basis of the NUTS 1 codes, Italy can be divided into three main macro-areas: North (Northwest Italy—ITC code—and Northeast Italy—ITD), Centre (Central Italy—ITE) and South (South Italy—ITF—and Insular Italy—ITG).
As explained in the Sect. 2, the Italian labour market is characterised by geographic discrepancies in labour market (and economic) indicators. For additional details on the statistics presented in the second section, see the online data warehouse of the ISTAT, http://dati.istat.it/. For details on the relevance of estimating a steady-state unemployment rate by geographic area in Italy, see Salituro and Scorcu (2001).

The measure of employees used, i.e., full-time equivalent labour units, is more appropriate than the measure used in earlier models in which labour demand was specified in terms of hours worked, and the number of employees was derived through an estimate of hours per worker. This latter approach, as emphasised by the literature—e.g., Baussola (2007) for Italy, and Fauser (2011) for Germany, could not completely account for the labour-hoarding effect determined by, for instance, hours spent within the Cassa Integrazione Guadagni, which allowed workers to remain employed (instead of being laid off) when firms were restructuring their plants, particularly during recessions. These factors must be taken into account when analysing the Italian economy because in the 40-year period examined in this paper, there were two recessions (at the beginning of the 1990s and since 2008).
It is worth highlighting that the decrease in the regional gaps and in general in the differences observed for gender and other characteristics may have been affected by a change in the Labour Force Survey methodology that occurred in 2004. This change significantly reduced the overall unemployment rate by excluding that part of the population that was discouraged and although available to work, did not consistently search for employment. For more detail, see Commission Regulation (EC) No. 1897/2000 of 7 September 2000 implementing Council Regulation (EC) No. 577/98 on the organisation of a labour force sample survey in the European Community concerning the operational definition of unemployment.
Given the small number of observations (the time series dimension T of the sample is equal to 40), which is insufficient to obtain robust results in an application of time series tests, economic theory is used to directly derive relationships and to impose an error correction mechanism as an auxiliary adjustment rather than interpreting the results of the time series relationships modelled in the data (see Kennedy 2008, p. 307).
The discouraged workers effect hypothesis is originally attributed to Tella (1964), who estimated a significant discouraged worker effect for both males and females in the US using employment-to-population rates as the explanatory variable. The hypothesis has been extensively used in the literature. For instance, Benati (2001) reviews numerous studies that attempted to estimate the discouraged worker effect, both at the aggregate level and for disaggregated sex-age groups.
For a detailed description of the labour market transition probability matrix, see Baussola and Mussida (2014a).
The features of the data employed in the present work (see the Sect. 2) allow the use of Markov chains models. Because individuals are observed at discrete time points, the exact transition times are not observed, and all that is known is the state occupied at the time of each scheduled survey. The Markov chain approach, as also explained by Aeschimann et al. (1999), allows one to describe the evolutions of the labour market transition probabilities for individuals who are not continuously observed over time.
For example, for the state of (E)mployment, there are the permanence rate (ee) in the condition and two outflows, the transition from employment to unemployment (eu) and the transition from employment to inactivity (en). The same criteria apply for the states of (U)nemployment and (N)on-labour force or inactivity.
It would have been interesting to detail the investigation at a regional level, but there are problems of relative sample sizes (the sample sizes of smaller regions, e.g. Aosta Valley or Abruzzo, are too small to obtain statistically significant estimates).
Obtained by multiplying the MNL coefficient estimates of the variable for each individual characteristic used in the model and their means.
The MNL coefficient estimates of the regional unemployment rates multiplied by \(UR_t\), which is the unemployment rate (regional) computed by using identity (7.8) of the macro-level identities module of the model.
In fact the behavioural equation residuals turn out to be significantly correlated. In this sense, a SUR estimation allows the estimation efficiency to be significantly improved (see also Fauser 2011).
Education is divided into four levels: absence of or low education, lower secondary education, diploma or secondary education, and degree or tertiary education (baseline category).
As in the macro model, the use of full-time equivalent labour units appears to be more appropriate than a simple head count of employees.
Wald tests for the null hypothesis of the equality of coefficients across geographic areas and years were calculated.

Disadvantaged workers are defined by the European Commission (2012) (Commission Regulation (EC) No. 2204/2012 of 12 December 2002 on the application of Articles 87 and 88 of the EC Treaty to State aid for employment [article 2]) as “any person who belongs to a category which has difficulty entering the labour market without assistance”.
