How do very open economies adjust to large immigration flows? Recent evidence from Spanish regions

In recent years, Spain has received unprecedented immigration flows. Between 2001 and 2006 the fraction of the population born abroad more than doubled, increasing from 4.8% to 10.8%. For Spanish provinces with above-median inflows (relative to population), immigration increased by 24% the number of high school dropouts while only increasing college graduates by 11%. We study different channels by which regional labor markets have absorbed the large increase in relative supply of low educated workers. We identify the exogenous supply shock using historical immigrant settlement patterns by country of origin. Using data from the Labor Force Survey and the decennial Census, we find a large expansion of employment in high immigration regions. Disaggregating by industry, the absorption operated through large increases in the share of low-educated workers, compared to the same industry in low-immigration regions. We do not find changes in sectoral specialization. Overall, and perhaps surprisingly, the pattern of absorption is very similar to the one found in the US.Immigration, Open Economies, Rybcszynski, Instrumental Variables

Immigration and housing booms: Evidence from Spain

We estimate empirically the effect of immigration on house prices and residential construction activity in Spain over the period 1998-2008. This decade is characterized by both a spectacular housing market boom and a stunning immigration wave. We exploit the variation in immigration across Spanish provinces and construct an instrument based on the historical location patterns of immigrants by country of origin. The evidence points to a sizeable causal effect of immigration on both prices and quantities in the housing market. Between 1998 and 2008, the average Spanish province received an immigrant inflow equal to 17% of the initial working-age population. We estimate that this inflow increased house prices by about 52% and is responsible for 37% of the total construction of new housing units during the period. These figures imply that immigration can account for roughly one third of the housing boom, both in terms of prices and new construction.Housing market, immigration, house prices, construction, Spain

Immigration, family responsibilities and the labor supply of skilled native women

This paper investigates the effects of Spain's large recentimmigration wave on the labor supply of highly skilled native women. Wehypothesize that female immigration led to an increase in the supply ofaffordable household services, such as housekeeping and child or elderlycare. As a result, i) native females with high earnings potential were ableto increase their labor supply, and ii) the effects were larger on skilledwomen whose labor supply was heavily constrained by familyresponsibilities. Our evidence indicates that over the last decadeimmigration led to an important expansion in the size of the householdservices sector and to an increase in the labor supply of women in highearningoccupations (of about 2 hours per week). We also find thatimmigration allowed skilled native women to return to work sooner afterchildbirth, to stay in the workforce longer when having elderlydependents in the household, and to postpone retirement.Methodologically, we show that the availability of even limited Registrydata makes it feasible to conduct the analysis using quarterly householdsurvey data, as opposed to having to rely on the decennial Census.Immigration, labor supply, fertility, retirement, household services

Rpd3L and Hda1 histone deacetylases facilitate repair of broken forks by promoting sister chromatid cohesion

Genome stability involves accurate replication and DNA repair. Broken replication forks, such as those encountering a nick, lead to double strand breaks (DSBs), which are preferentially repaired by sister-chromatid recombination (SCR). To decipher the role of chromatin in eukaryotic DSB repair, here we analyze a collection of yeast chromatin-modifying mutants using a previously developed system for the molecular analysis of repair of replication-born DSBs by SCR based on a mini-HO site. We confirm the candidates through FLP-based systems based on a mutated version of the FLP flipase that causes nicks on either the leading or lagging DNA strands. We demonstrate that Rpd3L and Hda1 histone deacetylase (HDAC) complexes contribute to the repair of replication-born DSBs by facilitating cohesin loading, with no effect on other types of homology-dependent repair, thus preventing genome instability. We conclude that histone deacetylation favors general sister chromatid cohesion as a necessary step in SCR

Work distributions on quantum fields

We study the work cost of processes in quantum fields without the need of projective measurements, which are always ill-defined in quantum field theory. Inspired by interferometry schemes, we propose a work distribution that generalizes the two-point measurement scheme employed in quantum thermodynamics to the case of quantum fields and avoids the use of projective measurements. The distribution is calculated for local unitary processes performed on KMS (thermal) states of scalar fields. Crooks theorem and the Jarzynski equality are shown to be satisfied, and some features of the resulting distributions are studied as functions of temperature and the degree of spatio-temporal localization of the unitary operation. We show how the work fluctuations become much larger than the average as the process becomes more localized in both time and space.Outgoin

Application of a Natural Language Interface to the Teleoperation of a Mobile Robot

IFAC Intelligent Components for Vehicles, Seville, Spain, 1998This paper describes the application of a natural language interface to the teleoperation of a mobile robot. Natural language communication with robots is a major goal, since it allows for non expert people to communicate with robots in his or her own language. This communication has to be flexible enough to allow the user to control the robot with a minimum knowledge about its details. In order to do this, the user must be able to perform simple operations as well as high level tasks which involve multiple elements of the system. For this ones, an adequate representation of the knowledge about the robot and its environment will allow the creation of a plan of simple actions whose execution will result in the accomplishment of the requested tas
