Studies of the relationship between aid and trade and the fiscal implications of emigration and HIV/AIDS interventions
- 2009

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis consists of three studies; two on fiscal effects of demographic change and one on the correlation between international aid and trade flows. Fiscal Implications of Emigration. This study examines the fiscal effects of emigration. A dynamic macroeconomic framework is used. The net present value of the fiscal effects of different types of individuals' emigration decisions is calculated. Individuals are differentiated with relation to age, gender, education, being immigrants or born in Sweden and how long they choose to stay abroad in case of emigration. The study explores how the fiscal effects of emigration are contingent on these different personal characteristics and it is applied to the case of emigration from Sweden in 1998. The estimated aggregate fiscal cost is 0.62% of GDP. This cost is significantly larger than the cost of immigration. Fiscal Implications of AIDS in South Africa. In this paper, I study the fiscal implications of the HIV/AIDS epidemic in South Africa in a standard neoclassical growth model. I find that an antiretroviral program is to a large extent self financing. An improvement in dependency ratios and health care cost savings would pay for Rand 144 billion of a full epidemiological intervention. The indirect effect through the changing demographic structure will be more important than the direct health care cost saving effect. Tied Aid, Trade-Facilitating Aid or Trade-Diverting Aid? Donor aid is often regarded as being informally tied (aid increases donor-recipient exports). However, in this paper, using a gravity model, we show that aid is also positively associated with recipient-donor exports. That is, aid increases bilateral trade flows in both directions. Our interpretation is that an intensified aid relation reduces the effective cost of geographic distance. We find a particularly strong relation between aid in the form of technical assistance and exports in both directions.

SWE-CLARIN partner presentation : Natural Language Processing Resources from the Department of Linguistics, Stockholm University
- 2014
-
Ingår i: The first Swedish national SWE-CLARIN workshop.
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- The aim of the CLARIN Research Infrastructure and SWE-CLARIN is to facilitate for scholars in the humanities and social sciences to access primary data in the form of natural language, and to provide tools for exploring, annotating and analysing these data. This paper gives an overview of the resources and tools developed at the Department of Linguistics at Stockholm University planned to be made available within the SWE-CLARIN project. The paper also outlines our collaborations with neighbouring areas in the humanities and social sciences where these resources and tools will be put to use.

Tidskriftsartikel (refereegranskat)abstract
- We used data from two population-based longitudinal studies to estimate time of onset and rate of accelerated decline across cognitive domains before dementia diagnosis. The H70 includes an age-homogeneous sample (127 cases and 255 non-cases) initially assessed at age 70 with 12 follow-ups over 30 years. The Kungsholmen Project (KP) includes an age-heterogeneous sample (279 cases and 562 non-cases), with an average age of 82 years at initial assessment, and 4 follow-ups spanning 13 years. We fit mixed linear models to the data and determined placement of change points by a profile likelihood method. Results demonstrated onset of accelerated decline for fluid (speed, memory) versus crystallized (verbal, clock reading) abilities occurring approximately 10 and 5 years before diagnosis, respectively. Although decline before change points was greater for fluid abilities, acceleration was more pronounced for crystallized abilities after the change points. This suggests that onset and rate of acceleration vary systematically along the fluid-crystallized ability continuum. There is early onset in fluid abilities, but these changes are difficult to detect due to substantial age-related decline. Onset occurred later and acceleration was greater in crystallized abilities, suggesting that those markers may provide more valid identification of cases in later stages of the prodromal phase.
