Konferensbidrag (refereegranskat)abstract
- The three year EU project SMARTER-SI that ends in January 2018 has tested a new concept for small lot manufacturing for SMEs which we call the Cooperative Foundry Model (CFM). During previous research, all RTOs have completed building blocks, i.e. components or parts of systems which are readily available and characterized by their high Technology Readiness Level (TRL). These building blocks are combined and integrated in so-called Application Experiments (AEs), thereby creating innovative Smart Systems that serve the SMEs' needs. Four pre defined AEs have been presented before [1] and in this paper, six additional AEs will be presented: i) a smart sensor for pneumatic combined clutch and brakes, ii) smart well plates for tissue engineering integrating continuous, non-invasive TEER iii) microclimate sensor for moisture applications, iv) LTCC-Si-Pressure Sensor, v) miniaturized capillary electrophoresis system for bio analysis, and vi) a MEMS sensor module for respiratory applications. Finally, a brief description of ongoing standardization efforts is presented.

A balanced millimeter wave doubler based on pseudomorphic HEMTs
- 1992
-
Ingår i: 1992 IEEE MTT-S International Microwave Symposium Digest. - 0149-645X. ; 1, s. 353-356

Konferensbidrag (refereegranskat)abstract
- A balanced HEMT (high electron mobility transistor) doubler for operation at millimeter waves has been analyzed, fabricated, and characterized. Particular attention has been paid to the influence of the output circuit on the performance of the doubler. The doubler was analyzed with a harmonic balance method and an output power of 4 dBm at 42 GHz was obtained experimentally. The conversion gain is approximately -1 dB at 40 GHz at an input power of 5 dBm. Bias and frequency response were very close to the predicted ones.

Family, Neighborhoods, and Health : Conditions for the Development of Human Capabilities

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Essay 1: We use data from a large sample of adoptees born in Sweden to decompose the intergenerational persistence in health inequality across generations into one pre-birth component, measured by the biological parents’ longevity, and one post-birth component, measured by the adopting parents’ longevity. We find that most of the health inequality is transmitted via pre-birth factors. In the second part of the paper, we study the background to why children of parents with better educational attainments have better health by decomposing the association into one component attributed to the education of the biological parents and one to the adopting ones. We find that the association can mostly be attributed to the adopting parents, suggesting that parental resources per se, rather than pre-birth (genetic) differences, make up the parental education gradient in child health.Essay 2: There are large differences in health across neighborhoods in Sweden. To try to answer if there is a causal link between neighborhood conditions in childhood and youth health, I apply two different empirical strategies. First, I use population wide data on families living in different areas in Sweden, and estimate the effects of childhood neighborhood on youth health using data on families that move across the country. Since the choice of moving and where to live is endogenous, I exploit the timing of moves and estimate the effect of siblings’ different exposure time to neighborhoods. The second approach utilizes a governmental policy that assigned refugees to their initial neighborhood in Sweden, potentially offering exogenous variation in neighborhoods and allowing me to study the effect of different neighborhoods on youth health. The findings from the two strategies together imply that there are significant neighborhood effects on youth health, but that the effects are contemporaneous and there is no evidence of exposure time effects.Essay 3: Previous research has shown that birth order affects outcomes such as educational achievements, IQ and earnings. The mechanisms behind these effects are still largely unknown. We examine birth order effects on health, and whether health at young age could be a transmission channel for birth order effects observed later in life. Our results show that firstborn children have worse health at birth. This disadvantage is reversed in early age and later-born siblings are more likely to be hospitalized for injuries and avoidable conditions. In adolescence and as young adults, younger siblings are more likely to be of poor mental health and to be admitted to hospital for alcohol induced health conditions. We also test for reverse causality by estimating fertility responses to the health of existing children. Overall our results suggest that birth order effects are due to differential parental investment because parents’ time and resources are limited.Essay 4: We study the short-, medium- and long-term consequences of health at birth using administrative data from Sweden for individuals born in the years 1973-1979. We contribute to a better understanding of the consequences of early life health by contrasting the effects of birth weight with two other measures of neonatal health: the length and the head circumference of the newborn. Our findings suggest that the use of birth weight alone might lead to an underestimation of the importance of early health. Furthermore, we find that there is a persistent effect of neonatal health on a variety of human capital measures in adolescence and adulthood.

Immigration: Policies, Mobility, and Integration
- 2019

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Essay I: Labor immigration is an important tool that countries can use to address labor shortages. The design of labor immigration policies may affect flows and the composition of immigrant workers, which can, in turn, have an effect on firms and workers in the host country. I quantify such effects by studying a major Swedish reform that made it significantly easier for firms to recruit non-Europeans. Using a difference-in-differences setup, I exploit variation in the strictness of immigration rules which affected industries differentially before and after the reform. Treated industries are predominantly lower-skilled, and concentrated in sectors like hotels and restaurants and retail trade sectors. Using linked employer-employee data, I study the effect of the reform on both firm-level and individual-level outcomes. I find that the mean earnings at firms in treated industries unambiguously increase. Firms also seem to take advantage of skill complementarities between natives and immigrants and intensify their overall hiring of high-skilled workers. Moreover, I follow native incumbents' employment and earnings over time and find heterogeneous effects along the skill and age dimensions.Essay II (with Matz Dahlberg, Mattias Engdahl and Till Nikolka): We evaluate the importance of spillover effects of national migration policies by estimating the effect of stricter rules on family reunification in Denmark in 2002 on migration to neighboring countries. We reach two main conclusions. First, we show that stricter rules for reunification lead to a clear and significant increase in emigration of Danish citizens with immigrant background. Most of the emigrants left Denmark for Sweden, a neighboring country in which reunification was possible. Second, we demonstrate that a significant fraction of the individuals that came to Sweden to reunite with a partner left the country again; within two (eight) years around 20% (50%) had left, with the absolute majority leaving for Denmark. Our results indicate that potential spillover effects from national migration policies should be taken into account when forming migration policy.Essay III (with Valentin Bolotnyy): We use administrative Swedish data to show that, conditional on parent income, immigrant children have similar incomes and higher educational attainment in adulthood than native-born Swedes. This result, however, masks the fact that immigrant children born into poor families are more likely than similar natives to both reach the top of the income distribution and to stay at the bottom. Immigrant children from high-income families are also more likely than natives to regress to the economic bottom. Notably, however, children from predominantly-refugee sending countries like Bosnia, Syria, and Iran have higher intergenerational mobility than the average immigrant child in Sweden.Essay IV (with Valentin Bolotnyy): Home ownership is an important indicator of socio-economic status and a good proxy for wealth. We show that on average, children of immigrants are less likely to own their homes than children of natives at age thirty. The difference remains even after we control for socio-economic characteristics, parental background, and municipality of residence. We find that parental background - both in terms of parents' income and education, but also their own home ownership status - is the most important determinant of home ownership in adulthood. We additionally investigate the role of age at arrival on outcomes in adulthood and find a significant negative effect of age at arrival on income and education, which also translates into a lower probability of owning a home in adulthood. However, growing up in a highly-educated family may partly mitigate this negative effect.
