The effect of polytechnic reform on migration
2011
This paper examines the effect of the polytechnic reform on geographical mobility. A polytechnic, higher education reform took place in Finland in the 1990s. It gradually transformed former vocational colleges into polytechnics and also brought higher education to regions that did not have a university before. This expansion of higher education provides exogenous variation in the regional supply of higher education. The reform raised the mobility of high school graduates across local labour markets in the years after they had completed their secondary studies, which indicated increased mobility between high school and post-secondary education. We estimate that the reform enhanced the annual…
Inverse problems for elliptic equations with fractional power type nonlinearities
2020
We study inverse problems for semilinear elliptic equations with fractional power type nonlinearities. Our arguments are based on the higher order linearization method, which helps us to solve inverse problems for certain nonlinear equations in cases where the solution for a corresponding linear equation is not known. By using a fractional order adaptation of this method, we show that the results of [LLLS20a, LLLS20b] remain valid for general power type nonlinearities.
The effect of education on migration: evidence from school reform
2010
A polytechnic, higher education reform took place in Finland in the 1990s. It gradually transformed former vocational colleges into polytechnics and expanded higher education to all Finnish regions. We implement instrumental variables estimators that exploit the exogenous variation in the regional availability of polytechnic education together with matriculation exam scores. Our IV results show that polytechnic graduates have a higher migration probability than those of vocational college graduates. However, a master’s degree did not increase migration propensity in comparison with a polytechnic degree. We also find that an increase in the availability of polytechnic education did not reduc…
Solutions of elliptic equations with a level surface parallel to the boundary: stability of the radial configuration
2016
A positive solution of a homogeneous Dirichlet boundary value problem or initial-value problems for certain elliptic or parabolic equations must be radially symmetric and monotone in the radial direction if just one of its level surfaces is parallel to the boundary of the domain. Here, for the elliptic case, we prove the stability counterpart of that result. We show that if the solution is almost constant on a surface at a fixed distance from the boundary, then the domain is almost radially symmetric, in the sense that is contained in and contains two concentric balls $${B_{{r_e}}}$$ and $${B_{{r_i}}}$$ , with the difference r e -r i (linearly) controlled by a suitable norm of the deviation…
Does Commuting Reduce Wage Disparities?
2004
ABSTRACT This paper shows that in the Baltic countries, commuting reduces urban-rural wage and employment disparities and increases national output. To quantify the effect of commuting on wage differentials, two sets of earnings functions are estimated (based on Estonian, Latvian, and Lithuanian Labor Force Surveys) with location variables (capital city, rural, etc.) measured at the workplace and at the place of residence. We find that the ceteris paribus wage gap between capital city and rural areas, as well as between capital and other cities is significantly narrowed by commuting in some cases but remains almost unchanged in others. Different outcomes are explained by country-specific s…
Job Displacement, Inter-Regional Mobility and Long-Term Earnings
2018
We examine the effect of job displacement on regional mobility using linked employer-employee panel data for the 1995-2014 period. We also study whether displaced movers obtain earnings and employment gains compared to displaced stayers. The results show that job displacement increases the migration probability by ~70%. However, social capital in a region and housing characteristics decrease the propensity to move, indicating that people do not make the migration decisions solely based on short-term economic incentives. Migration has an immediate negative relationship with earnings, but the link diminishes as time passes and eventually turns positive for men. The link between migration and …
Determinants of inter-regional migration in the Baltic countries
2003
We show that Estonia, Latvia and Lithuania despite small geographical size feature considerable and persistent regional disparities. Registered migration rates have declined dramatically since the last years of Soviet era, yet they are high by international standards. Evidence from regional inflows and outflows in Latvia and from Estonian labour force survey is used to show that regional unemployment and especially wage differentials, as well as demographic factors, have a significant impact both on gross and net migration flows. Age and education effects are consistent with predictions of the human capital model of migration. Unemployed persons, as well as commuters between regions, are si…
An inverse problem for the minimal surface equation
2022
We use the method of higher order linearization to study an inverse boundary value problem for the minimal surface equation on a Riemannian manifold $(\mathbb{R}^n,g)$, where the metric $g$ is conformally Euclidean. In particular we show that with the knowledge of Dirichlet-to-Neumann map associated to the minimal surface equation, one can determine the Taylor series of the conformal factor $c(x)$ at $x_n=0$ up to a multiplicative constant. We show this both in the full data case and in some partial data cases.
Determining an unbounded potential for an elliptic equation with a power type nonlinearity
2022
In this article we focus on inverse problems for a semilinear elliptic equation. We show that a potential $q$ in $L^{n/2+\varepsilon}$, $\varepsilon>0$, can be determined from the full and partial Dirichlet-to-Neumann map. This extends the results from [M. Lassas, T. Liimatainen, Y.-H. Lin, and M. Salo, Partial data inverse problems and simultaneous recovery of boundary and coefficients for semilinear elliptic equations, Rev. Mat. Iberoam. (2021)] where this is shown for H\"older continuous potentials. Also we show that when the Dirichlet-to-Neumann map is restricted to one point on the boundary, it is possible to determine a potential $q$ in $L^{n+\varepsilon}$. The authors of arXiv:2202.0…
Losing a Job and (Dis)incentives to Move
2020
Tässä tutkimuksessa tarkastellaan työpaikan menettämisen ja muiden taloudellisten ja ei-taloudellisten kannustimien vaikutuksia alueelliseen muuttoliikkeeseen. Käytämme yhdistettyä työnantaja-työntekijäaineistoa sekä tietoja alueellisista asuntomarkkinoista. Työpaikan menettäneillä tarkoitamme heitä, jotka menettävät työpaikkansa toimipaikan sulkemisen tai joukkoirtisanomisen takia. Työpaikan menetys lisää henkilön muuttoalttiutta noin 80 prosentilla. Työpaikan menettäneet näyttäisivätkin reagoivan taloudellisiin kannustimiin, sillä alhainen oletettu palkkataso ja korkeat asuntojen hinnat alueella ovat yhteydessä lisääntyneeseen muuttoalttiuteen alueelta, josta henkilö on jäänyt työttömäksi…
