Voting over Selective Immigration Policies with Immigration Aversion

Selective immigration policies set lower barriers to entry for skilled workers. However, simple economic intuition suggests that skilled majorities should welcome unskilled immigrants and protect skilled natives. This paper studies the voting over a selective policy in a two-country, three-factor model with skilled and unskilled labor, endogenous migration decisions, costly border enforcement and aversion to immigration. Results show that heterogeneity in capital distribution forces skilled voters to form a coalition with unskilled voters, who become pivotal. The voting outcome is therefore biased towards the preferences of the latter, and consists in a selective protectionism. Finally, immigration aversion helps to explain why skilled majorities do not bring down entry barriers against unskilled workers.selective immigration policies, multidimensional voting, cultural preferences, Condorcet winner

Voting over Selective Immigration Policies with Immigration Aversion

The claim that "skilled immigration is welcome" is often associated to the increasing adoption of selective immigration policies. I study the voting over differentiated immigration policies in a two-country, three-factor one-period model where there exist skilled and unskilled workers, migration decisions are endogenous, enforcing immigration restriction is costly, and natives dislike unskilled immigration. According to my findings, decisions over border closure are made to protect the median voter when her capital endowment is sufficiently small. Therefore I argue that the professed favour for skilled immigration veils the protection for the insiders. This result is confirmed by the observation that entry is rationed for both skilled and unskilled workers. Moreover, immigration aversion helps to explain the existence of entry barriers for unskilled workers in countries where the majority of voters is skilled.Selective immigration policies, multidimensional voting, Condorcet winner.

The claim that "skilled immigration is welcome" is often associated to the increasing adoption of selective immigration policies. I study the voting over differentiated immigration policies in a two-country, three-factor general equilibrium model where there exist skilled and unskilled workers, migration decisions are endogenous, enforcing immigration restriction is costly, and natives dislike unskilled immigration. According to my findings, decisions over border closure are made to protect the median voter when her capital endowment is sufficiently small. Therefore I argue that the professed favour for skilled immigration veils the protection for the insiders.

Who Contributes? A Strategic Approach to a European Immigration Policy

According to the Lisbon Treaty the increasing cost of enforcing the European border against immigration shall be shared among the EU members. Nonetheless, the Treaty is rather vague with respect to the "appropriate measures" to adopt in order to distribute the financial burden. Members who do not share their borders with source countries have an incentive to free ride on the other countries. We study a contribution game where a northern government and a southern government minimize a loss function with respect to their national immigration target. We consider both sequential and simultaneous decisions and we show that the contribution of both governments is positive when their immigration targets are not too different. We show that total contribution is higher when decisions are simultaneous, but the conditions for both contributions to be positive are less restrictive in the sequential framework.Policy making, Government expenditures, Local government expenditures, Federalism

Aggregate Employment Dynamics and (Partial) Labour Market Reforms

European labour markets have undergone several important innovations over the last three decades. Most countries have reformed their labour markets since the mid-1990s, with the liberalization of fixed-term contracts and temporary work agencies being the common elements to such reforms. This paper investigates the existence of a change in the dynamic behaviour of the aggregate employment for major European Union countries - France, Germany, Italy, and Spain. According to our results, partial labour market reforms have made the response of the aggregate employment to output shocks larger and quite comparable to that found for the UK - the most flexible labour market in Europe since the Thatcher reforms.labour market deregulation; dynamic responses

High-energy string-brane scattering: leading eikonal and beyond

We extend previous techniques for calculations of transplanckian-energy string-string collisions to the high-energy scattering of massless closed strings from a stack of N Dp-branes in Minkowski spacetime. We show that an effective non-trivial metric emerges from the string scattering amplitudes by comparing them against the semiclassical dynamics of high-energy strings in the extremal p-brane background. By changing the energy, impact parameter and effective open string coupling, we are able to explore various interesting regimes and to reproduce classical expectations, including tidal-force excitations, even beyond the leading-eikonal approximation.Comment: 40 pages, 5 figures, v2: minor corrections, new appendix with a discussion of the Feynman diagrams contributing to the scattering amplitude in the field theory limi

Aspects of Land Take in the Metropolitan Area of Naples

Land take is a phenomenon of great concern nowadays because of the large number of its negative impacts regarding biological, economic and social balance. In Italy, the development of urban and other artificial land has been irreversibly transforming a nonrenewable resource such as soil, regardless the almost constant population rate, with different speed depending of the region considered. The aim of this paper is to analyze the phenomenon in the metropolitan area of Naples, which is an area highly affected by territorial aggression of human matrix. The data used are both by the Institute for Environmental Protection and Research (ISPRA) Report 2015 on the usage of the land and by ISTAT relating to the resident population up to the 1st of January 2015 and the extension of land for agricultural use (Census 2010). The mathematical combination of this data creates a new indicator that can be referred to as “residual land”; this residual area is of great extension with many different characteristics and it could represent the area where the phenomenon of land take most occurs. The identification, measurement and analysis of “residual land” provide new insights on the evolution of land take and this new indicator can represent a critical element to work on to prevent future land transformation and protect natural and agricultural areas within the Italian context

Production and reuse of waste in rural area with high density of greenhouse

Agricultural activities cause the production of considerable amounts of waste sometimes dangerous that must be properly handled to avoid negative impacts on rural areas and on agroecosystems. The estimation of qualitative and quantitative characteristics of agricultural waste products and the capacity of rural land of transposing organic matter deriving from the processes of composting, is a key point for the planning and management of the waste integrated cycle. The aims of this study are the evaluation of the quantities of various types of agricultural waste on territorial scale, the amount of compost that can be used in rural areas affected by different cultures and the effectiveness of community composter in the treatment of vegetable agricultural waste for the production of green composted soil. These assessments were carried out in an area of study characterized by a high spatial density of greenhouses. The methodological procedure used is based on the use of agricultural waste production coefficients and maximum application rates of compost for cultivation. The results show the role and potential of the agricultural areas in the waste cycle from production to the potential reuse of recovered material

Acrocyanosis, digital ischemia and acronecrosis as first manifestations of endometrial adenocarcinoma: case presentation and literature review

The association between digital ischemia and cancer is rarely reported in literature and the exact mechanism of this occurrence has not been completely understood. We report here a case of a 73 yearold woman who presented digital ischemia as first manifestation of endometrial adenocarcinoma. Reporting this rare clinical case and with a brief literature review, we recommend to consider an intensive search for primary and metastatic cancer in all patients who experience a digital ischemia, with the aim to early detect and treat the disease
