  1. 1. Skattning av skogsbestånds kapitalförräntning – utifrån Skogliga grunddata

    University essay from SLU/Dept. of Forest Resource Management

    Author : Henrik Wikman; [2019]
    Keywords : avkastning; direktavkastning; ekonomi; investering; kapitalförräntning; lönsamhet; risk; räntabilitet; slutavverkning; skattning; skog; skogliga grunddata; virke; värdetillväxt;

    Abstract : Ett skogsbestånds monetära virkesproduktionsvärde kan beräknas som bruttointäkt minus avverkningskostnad. Såväl bruttointäkt som avverkningskostnad beror på skogstillståndet; främst beståndets volym per arealenhet, medelstammens volym och virkeskvaliteten. READ MORE

  2. 2. Summation By Parts Finite Difference Methods with Simultaneous Approximation Terms for the Heat Equation with Discontinuous Coefficients

    University essay from Linnéuniversitetet/Institutionen för matematik (MA)

    Author : Niklas Kåhlman; [2019]
    Keywords : Finite Difference Method; FDM; Summation By Parts; Simultaneous Approximation Terms; SBP-SAT; Heat Equation; Poisson s Equation; Discontinuous Coefficients; Piecewise Constant Coefficients; Convergence; Dual Consistency; Stability;

    Abstract : In this thesis we will investigate how the SBP-SAT finite difference method behave with and without an interface. As model problem, we consider the heat equation with piecewise constant coefficients. The thesis is split in two main parts. READ MORE

  3. 3. Returns to schooling and potential signalling effects: Estimates based on ISSP data on Sweden

    University essay from Lunds universitet/Nationalekonomiska institutionen

    Author : Emil Bergman; Carl-Gustav Schöön; [2018]
    Keywords : Returns to schooling; Signalling effects of education; Mincer equation; Ability bias; years of schooling; Business and Economics;

    Abstract : This thesis estimates the returns to schooling in Sweden for working individuals by applying the Mincer equation on three datasets from the International Social Survey Programme and compare the results to assess potential trends. It also investigates if there is any difference in returns to schooling for men and women and if there seem to be any signalling effects present. READ MORE

  4. 4. Improved estimation of the ATT from longitudinal data

    University essay from Umeå universitet/Statistik

    Author : Kreske Ecker; [2018]
    Keywords : ;

    Abstract : Our goal is to improve the estimation of the average treatment effect among treated (ATT) from longitudinal data. When the ATT is estimated at one time point (or separately at each), outcome-regression (OR), inverse probability weighting and doubly robust estimators can be used. READ MORE

  5. 5. Coefficients and zeros of mixed characteristicpolynomials

    University essay from KTH/Matematik (Avd.)

    Author : Samuel Zackrisson; [2017]
    Keywords : ;

    Abstract : The mixed characteristic polynomial (MCP) was introduced in the papersof Marcus, Spielman and Srivastava from 2013 on Ramanujan graphs and the Kadison-Singerconjecture. Several known results and open problems can be formulated in termsof MCPs. The proofs of Marcus, Spielman and Srivastava involve bounding theroots of certain MCPs. READ MORE
