Agglomeration and growth: the effects of commuting costs
We present a model of industrial location and endogenous growth with congestion costs. According to the interplay between knowledge spillovers and commuting costs, we are able to obtain both a Krugman-type and a bell-shaped agglomeration outcome. In the first case, the economy experiences a permanent income inequality in the steady state and income divergence in the transitional dynamics. In the second case, we observe an enlargement of the industrial core of the economy with a strong catching up by the periphery. Welfare analysis shows that congestion create (in the bell-shaped agglomeration case) a negative welfare effect on peripheral unskilled workers and renders the agglomerated equilibrium Pareto inferior to dispersion.Congestion, Endogenous Growth, Migration
Immigrant earnings in the Italian labour market
The aim of this paper is to assess the relationship between individual skills and labour market performance of immigrants residing in Lombardy during the period 2001-2005. We use a recent dataset collected by the NGO ISMU, which includes information on individual characteristics and the legal status of each immigrant. Our results show that returns on schooling are positive and range from 0.8 per cent to 0.9 per cent, a figure that is much lower than the one estimated for native Italians. This result is robust to a number of specifications and tests. In particular, it is not influenced by the legal status of the alien or by a possible self-selection in the labour supply. Moreover, although more talented immigrants tend to self-select in the Lombardy region compared with the other Italian regions, their return on schooling remains low compared with natives. We also show that a certain heterogeneity exists across educational levels and countries of origin: immigrants from Eastern Europe are better able to exploit their human capital, especially when they hold a university degree, while the school-wage profile of Latin Americans and Asians is basically flat. Finally, there is some evidence of a cohort effect in migration, but this tends to impact on the return on experience rather than on the return on schooling.Immigration, return on schooling, return on experience
Skills or culture? An analysis of the decision to work by immigrant women in Italy
Activity and employment rates for immigrant women in many industrialized countries display a great variability across national groups. The aim of this paper is to assess whether this well-known fact is due to a voluntary decision (i.e. large reservation wages by the immigrants) or to an involuntary process in that the labour market evaluation of their skills is low. This is done by estimating the reservation wages for each individual in the dataset. Our results show that low activity and employment rates for certain national groups are not associated with high reservation wages. This implies that low participation should not be interpreted as a voluntary decision.Reservation wages, female labour supply, cross-national differences
Policies for local development: an evaluation of Italy's "Patti Territoriali"
In Italy, Patti Territoriali (Territorial Pacts) are one of the main government-sponsored programmes to foster growth in disadvantaged areas. A territorial pact is an agreement among the local authorities and representatives of civil society (mainly entrepreneurs and trade unions) of a number of neighbouring municipalities that is subsequently endorsed by the central government. It consists in a fully-fledged development plan, including a series of private and public investments for which public funding is provided. This paper evaluates the effectiveness of territorial pacts by comparing the economic performance, in terms of employment and number of plants, of participating municipalities with a sample of municipalities not involved in the policy. The results suggest that the programme has been largely ineffective in stimulating growth.regional aid, regional growth, ownership
Skill-Biased Share-Altering Technical Change in Spatial General Equilibrium
The paper consider the skill-biased Ă¢ââÂŹĂ
âshare-alteringĂ¢ââÂŹĂ technical change hypothesis in a spatial general equilibrium model where skilled and unskilled individual may exhibit different preferences for local amenities. A main novelty Ă¢ââââŹĹboth for labour and urban economics- is that, under this hypothesis, skill-biased technical change can be readily represented by simple Cobb-Douglas production functions, rather than CES technologies. We then analyse the local labour markets equilibrium, where the adoption of new technologies may require an adequate proportion of skilled workers. Keywords: skill-biased technical change, share-altering technologies, local labour markets. JEL Classification Numbers: O33, R12, R23, J31.
Skill Polarization in Local Labour Markets under Share-Altering Technical Change
This paper considers the âshare-alteringâ technical change hypothesis in a spatial general equilibrium model where individuals have different levels of skills. Building on a simple Cobb-Douglas production function, our model shows that the implementation of skill-biased technologies requires a sufficient proportion of highly educated individuals. Moreover, areas that experiment this kind of technical change will initially exhibit a rise in local skill premia, but such a trend tends to be reverted over time due to labour mobility. Also, when technical progress is such to disproportionately replace middle-skill jobs, the local distribution of skill will exhibit âfat-tailsâ, where the proportion of both highly skilled and low-skilled workers increases. These predictions are consistent with recent existing evidence.share-altering technologies, local skill distribution, local wage premium.
Global Value Chains and the Great Recession: Evidence from Italian and German Firms
During the last two decades, profound changes in the international division of labour among firms have occurred, with impressive growth in outsourcing, off-shoring of some stages of production and the globalization of intermediates goods markets. This new model of the international division of labour has both initiated an increasing variety of relationships among producers and spurred the development of Global Value Chains. According to some recent research, Global Value Chains have been one of the main transmission mechanisms of the Great Trade Collapse that severely and simultaneously hit all OECD countries in 2009. Pervasive as it has been, it also appears that the impact of the crisis on firms involved in Global Value Chains has been highly heterogeneous. Our paper intends to contribute to this very recent and ongoing debate, providing a description of the effects of the crisis from a perspective that is both countrycomparative, Germany and Italy being the countries taken into consideration, and on firm level, as we pay particular attention to the positioning of the firms along Global Value Chains, i.e., whether intermediate or final firms- and to their strategies. Three are the main conclusions: i) intermediate firms were hit by the crisis more than final firms; ii) among intermediate firms, the ones that carried out innovation activities in the previous period (before 2008) were somewhat sheltered by the effect of crisis; iii) firms â positioning in GVCs and their strategies may help to explain the Italy-Germany performance gap
Processes driving freshwater plant production and diversity in upland streams
Upland headwater streams are important sources of freshwater in mountainous temperate to sub-arctic latitude European countries like Scotland. Yet much less is known about the ecology of small, characteristically oligotrophic, mountain streams supporting periphyton and aquatic bryophyte dominated vegetation, and their potential bioindicator capacity of environmental water quality, than lowland rivers impacted by anthropogenic disturbance, in this context. This scarcity of knowledge has significant implications for the success of the recently implemented Water Framework Directive (WFD: 2000/60/EC). The WFD is a major piece of environmental legislation for water policy and sustainable water management in Europe. New contributions are fundamental to environment agencies, such as the Scottish Environment Protection Agency (SEPA), tasked with the responsibility of enforcing WFD statutory requirements and developing effective biomonitoring tools for assessing water quality status in Scotland. A major aim of the WFD is to achieve at least âgoodâ ecological status of inland waterbodies by 2015. Further, in doing so, to ascertain ecological benchmark communities of near-pristine (or minimally-impacted) reference conditions as indicators of high water quality status. The objective is to improve understanding of the environmental processes driving the production and diversity of freshwater plant species-assemblages in upland streams. Such information can be used for assessing perturbations threatening the ecological integrity of rivers impacted by anthropogenic disturbances (human pressure). This enables environment agencies such as SEPA, to respond appropriately by implementing corrective measures and sustainable management strategies. This project monitored a range of near-pristine headwater streams of contrasting underlying geology in the Scottish Highlands. The approach adopted was compatible with current WFD river characterisation and biomonitoring strategies. These were used to investigate the structural and functional response of freshwater plant communities (chiefly diatoms and other algal groups; aquatic bryophyte and vascular submerged macrophyte vegetation) to environmental drivers (e.g. flow, substrate morphology, nutrient inputs, water chemistry, underwater light availability). The work was carried out with the aim of contributing to future development of baseline monitoring tools for assessing upland stream habitat quality in Scotland.EThOS - Electronic Theses Online ServiceGBUnited Kingdo
Legal Status and the Criminal Activity of Immigrants
We exploit exogenous variation in legal status following the January 2007 European Union enlargement to estimate its effect on immigrant crime. We difference out unobserved time-varying factors by (i) comparing recidivism rates of immigrants from the ânewâ and âcandidateâ member countries; and (ii) using arrest data on for eign detainees released upon a mass clemency that occurred in Italy in August 2006. The timing of the two events allows us to setup a difference-in-differences strategy. Legal status leads to a 50 percent reduction in recidivism, and explains one-half to two-thirds of the observed differences in crime rates between legal and illegal immigrants
The role of culture in firm-bank matching
We assemble a unique dataset containing population-level information on loan applications in a region hosting two cultural groups to study the role of culture in firm borrowing decisions. We find that firms are more likely to apply for loans from culturally close banks. This effect is stronger for opaque firms, but not for less performing firms, indicating that firms do not expect preferential treatment from same-culture banks. Loan applications to culturally distant banks increase sharply with firmsâ size and age, suggesting a role of information asymmetry in firm-bank matching. In contrast, we find no effect of cultural proximity on loan supply. Overall, our results show that demand-side factors play a key role in the formation of same-culture lending relationships
