    Issues on cross-cultural pragmatics: Swedish learners' attitudes regarding the learning of Japanese politeness strategies2016In: Abstracts, 2016Conference paper (Refereed)
    Abstract [en]

    Teaching communicative competence is considered extremely important in today’s language instruction. One can avoid embarrassing situations and conflicts caused by misunderstandings if one understands the differences in intercultural pragmatics. This study investigates the differences in politeness strategies between Swedish and Japanese discourse and how Japanese politeness strategies can be taught effectively to the Swedish learners of Japanese. Politeness discourse varies in complexity according to social distance, relative power between the speakers, and situations. It has been indicated in the course evaluations and comments from the students that Swedish learners of Japanese often do not see the necessity of learning the polite/honorific discourse and they often view these negatively as Swedish society is one of the most egalitarian in the world. As a consequence, Swedish students often fail to utilize appropriate politeness strategies when speaking in Japanese. However, it is important to point out to foreign language learners that cultural and social norms are not interchangeable and that one must adapt to the language one is using and the culture one is in. Thus Swedish Learners of Japanese should consider politeness discourse as a part of the rules of the language rather than something that can be modified based on one’s opinion. Student surveys and analysis of students’ errors I have complied during the past six years have revealed clear differences in the use of politeness strategies in Swedish and in Japanese context. While politeness, respect, and formality are closely intertwined in Japanese; the Swedes perceive respect and politeness as separate matters. It is also found that while the Japanese are inclined to use verbal politeness strategies, the Swedes express respect more through non-verbal actions or behaviors. This paper suggests ways in which learners of Japanese may overcome these differences.

    Migration, transformation, and the homecoming of a culture: Tango in Finland and Japan as an example2016In: Migration, transformation, and the homecoming of a culture: Tango in Finland and Japan as an example, 2016Conference paper (Refereed)
    Abstract [en]

    In Finland, a great distance away from Buenos Aires, people crowd dance floors nightly to dance to tango music, while the tango has also captured the hearts of the people on the other side of the world in Japan. The popularity of the tango in both Finland and Japan, however, is not so familiar to the outside world.

     

    In this paper, I will discuss the motives and the paths by which a culture travels, settles and shapes itself into a new form, using the tango as an example. First, the tango’s relationship to society and history in each of these countries are explored using archives and literature. Then such aspects as inner emotion, solitude, illusion, and liminality are analyzed through data collected from surveys, interviews, and forum discussions in the SNS.

     

    Some scholars suggest that the tango reflects the personality, mentality, and identity of the Finnish and Japanese peoples. Though this may be partially true, it is difficult to generalize about the Finnish or Japanese personality. It is argued, rather, that the tango's prosperity in these two countries has significant connections to some shared historical and social factors. I also propose that the 'liminality' of tango dancing plays an important role in both nations that went through difficult struggles to recover from the damage caused by war. “The liminal phase is considered sacred, anomalous, abnormal and dangerous, while the pre- and post-liminal phases are normal and a profane state of being” (Selänniemi 1996). Tango dancing can be considered an escape or a vacation from the hardship of everyday life as well as a fuel which enables the people to keep moving forward.

    The tango’s transformation in Finland and Japan, and its homecoming back to Argentina are also examined. The results reveal some of the unusual paths a culture can travel.

    Politeness as a part of intercultural competence2015In: Japanese Language Education in Europe, ISSN 1745-7165, Vol. 20, p. 395-396Article in journal (Refereed)
    Abstract [en]

    Teaching communicative competence is extremely important in language instruction. While politeness discourse varies in complexity according to social distance, relative power between the speakers, and situations, Swedish learners of Japanese often do not see the necessity of learning the polite/honorific discourse and often view these negatively as Swedish society is one of the most egalitarian in the world. However, it is important to point out to foreign language learners that cultural/social norms are not modifiable based on one’s opinion and that one must adapt to the language one is using and the culture one is in. The current study investigates the differences in politeness strategies between Swedish and Japanese discourse. Student surveys and analysis of students’ errors have revealed clear differences in the use of politeness strategies. While politeness, respect, and formality are closely intertwined in Japanese; the Swedes perceive respect and politeness as separate matters. It is also found that while the Japanese are inclined to use verbal politeness strategies, the Swedes express their respect more through non-verbal actions/behaviors. Various Japanese and Swedish utterances have also been examined to determine the DP default (Usami 2006) in order to systematize the politeness strategies in ways similar to grammatical rules.

    The Development of Identity and Intercultural Communicative Competence in NNS-NNS Online Interaction2019Conference paper (Refereed)
    Abstract [en]

    As demonstrated in recent studies of Computer-assisted language learning (CALL), authentic intercultural contexts can be created by using online exchanges to enhance students’ foreign language learning and identity. While research on telecollaboration and identity has mainly focused on NS-NNS interactions, this study examines NNS-NNS telecollaborative interactions.

    The study examines two sets of NNSs with different L1 backgrounds, namely NNSs of Japanese from universities in the US and Sweden. The project combines telecollaborative activities consisting of both asynchronous written (blogs) and synchronous verbal (online discussions).

    The Intercultural Dialogue (ID) model (Houghton, 2012) was used to evaluate the outcome. The model consists of five stages: 1) Analysis of Self; 2) Analysis of Other; 3) Critical analysis of value similarities (or differences) between Self and Other; 4) Critical evaluation of the values of Self and Other relative to a standard; and 5) Identity development.

    Results indicate that through their written and oral discussions, the students’ choice of words constructed images of the person they are or wished to be perceived as while building an understanding of their own identities. This shows that language use does not necessarily reflect who one is but is used to contribute to the construction of one’s identities. We also observed that there exists a stage prior to the first stage in the ID-model, namely a “no-awareness” stage. Furthermore, our findings indicate that Stage 1 “Awareness of Self” occurs as two sub-stages: 1-a) Awareness of single identity; and 1-b) Awareness of having multiple identities. Our data also suggest that at one point, several students were offering different critical evaluations of Self and Other as a result of their own and the Japanese cultural standard not fitting the standard identity development model, suggesting that the multicultural nature of NNS-NNS interactions involving different L1 backgrounds can accelerate identity development.

    湯気の中へ、非日常の世界へ:

    通過儀礼としてのフィンランドのサウナと日本の風呂

     

    遠く離れた北欧フィンランドと極東日本。気候もそこに暮らす人々も一見全く異なるこのふたつの国に共通する熱い湯気の文化がある。フィンランド人が長い歴史の中で大切にしてきた「サウナ」、そして多くの日本人にとって欠かせない「風呂」。どちらも身体を清潔にする場所というだけではなく、宗教的・文化的意味合いや、癒し、儀礼とも深く関係していると考えられている。1998年にはフィンランドのユヴァスキュラで風呂とサウナに関するエキシビションも催されている。

    本発表では、フィンランドと日本での過去20年間のフィールドワークの結果をもとに、サウナと風呂が、それぞれどのようにそこに暮らす人々の人生や日々の生活の節目に行われる通過儀礼(van Gennep 1909)として機能しているのかを明らかにし、サウナと風呂文化に共通して見られるリミナリティー (Turner 1974)を「マクロモデルとマイクロモデル」(Niendorf 2000)を用いて文化人類学的観点から検証する。

    Investigating the use of the verbs ”naru” in Japanese and ”bli” in Swedish through translation2013In: Nordic Association of Japanese and Korean Studies (NAJAKS): Abstracts for 2013, 2013Conference paper (Refereed)
    Abstract [en]

    This study investigates how use of the Swedish verb “bli” corresponds to the Japanese verb “naru” using translated materials as a corpus.  

     

    Japanese is said to be a situation-oriented language, while English is person-oriented.

              e.g., Mariko wa kekkon surukotoni NARImashita.

                       (It became so that Mariko will be married.)

                       ‘Mariko will get married’ in English.

     

    The Swedish verb ”bli” usually means ’to become’ or ’to be (as an auxiliary verb),’ yet is used more widely than these English meanings.

              e.g., Det blir 100 kronor, tack.

                       (100 kr ni NARI-masu.)

                       ’It makes/will be 100kr.’

     

    Examples like this lead to the observation that ”bli” is used in a context more similar to the Japanese verb ”naru.” than English verb “become.” Comparison of some translated materials also shows that “bli” is often translated into Japanese as “naru” while it is more likely to be replaced by a transitive or intransitive verb in English.

     

    However, erros such as

               *okoru ni NARU (verb ‘to be upset’+naru)

                  [okoru: a verb]

               *annshin ni NARU (noun ‘feeling at ease’ +naru)   

                  [annshin suru: a verb derived from a noun]

    which are made by Swedish learners of Japanese indicate that the translation of “bli” into Japanese is not so straight forward.

     

    In this study, we examined the following questions:

    1. How is ”bli” translated into Japanese/English?
    2. If ”bli” is translated into ”naru” in Japanese, in what grammatical context(s) does it occur?
    3. How are these variations related to the errors students make in translating ”bli” into  Japanese?

     

    In order to examine the above research questions, we conducted two separate studies:

     

    Study I: Examining how Swedish bli is translated into Japanese in literature translation

     

    Using children´s novels “Sommerboken” by Tove Jansson and “Pippi Långstrump” by Astrid Lindgren as the data source, all the sentences that contain bli were extracted along with their translations into English and Japanese. The extracted sentences were, then, categorized according to the various types of usage of the verb bli, and the translation into Japanese for each of those categories was analyzed.

     

    Study II: The translation of various uses of bli into Japanese by Swedish students

     

    Study I above showed usages of the verb bli in various context. In Study II, we tried to see if some of these usages cause more problems than the others for the Swedish students. The students in the Japanese-English translation course at Högskolan Dalarna (Sweden) were given 7 Swedish sentences containing various usages of bli, and were asked to translate them into Japanese. Then the accuracy of the translation and the translation techniques used were analyzed.

     

    The results from Study I showed that there were numerous usages of the verb bli, such as describing conditions, describing the changes of conditions, indicating certain emotional status, and so on, which naturally led to the variety in Japanese translation. Furthermore,  apart from the most literal translation, which is to use the verb naru, various types of compound verbs (main verb – help verb combinations) were used in order to express different nuances.

     

    In some of the usages identified above, translation shifts were obligatory when translated into Japanese; i.e. the literal translation was impossible, and the translator has to make minor changes from the ST (source text) to the TT (target text), such as changes of grammatical categories or of voice (e.g. passive to active).

     

    The results from the Study II show that the sentences which require more complicated translation shifts tend to cause more errors when students translate them into Japanese.

     

    Clarifying how the use of “bli” correlates with the use of “naru” will not only help Swedish students understand the use of the somewhat difficult concept of “naru,” but also help translators deal with this issue. Finding a more systematic way to translate “bli” into Japanese using more tokens from various genres would be necessary in order to achieve this.

    Creating an effective environment for development of intercultural competence through online Japanese Language exchanges: How it is done and what it takes2013Conference paper (Other academic)
    Abstract [en]

    Developing intercultural competence has been an important focal point of university education especially in the area of foreign language instruction. In order to incorporate intercultural competence in our Japanese language instruction, we have brought together students studying Japanese from the U.S., Korea and China to join our students studying Japanese in Sweden for online exchanges. In order to create an ideal virtual classroom environment in an international setting, we have examined how students from different countries interact during the online exchanges in Japanese. In this presentation, we will discuss the process, strength, difficulties and potential of such exchanges.

    言語教育におけるソーシャルネットワーキングアプローチ(以下 SNA)では、「他者の発見、自己の発見、つながりの実現」を理念に、従来の「わかる」「できる」能力に加え、新たに「つながる」能力を 重要視する(當作 2013)。SNAに基づいてことばと文化を学ぶことで、学習者の人間的成長が促され、社会力も獲得される。  本発表では、上記の教育理念を念頭に、異なる文化圏で学ぶ日本語学習者をオンラインでつないだ取り組みについて紹介する。実践には米国とスウェーデンの大学で中上級レベルの日本語を学ぶ学習者10名が参加した。1学期間、アイデンティティをテーマに授業を行い、非同期型ツールであるブログ、同期型ツールであるビデオ会議システムを利用して双方を継続的につないだ。  アンケート、インタビュー、観察データを分析した結果、学習者はこのようなオンラインでの交流により、言語面だけでなく、自己・他者のアイデンティティや文化について肯定的な視点を持つようになるという変化が見られた。これは自己・他者の新たな発見といえる。また、参加者は、日本に興味があるという共通点があるため、様々なトピックについて積極的に探求し、互いに教え学びあう関係を築くことが容易にできた。さらに「つながり」が形成されていくに従い、日本だけでなく米国やスウェーデンについてもより知りたいと考えるようになり、好奇心の幅が広がった。これはつながりの理想的な実現であるといえよう。  通常、海外の日本語学習者は、日本の英語学習者と交流するケースが多いが、この場合、母語話者に教えてもらうという一方向的な形のコミュニケーションをとりやすい。一方、異なる場所で学ぶ日本語学習者同士の交流の場合、対等な形でのコミュニケーションがとれ、場所によって日本の捉え方も違うことに気づくことで、多元的な視点で日本を捉え直すきっかけにもなる。これは学習者の言語・文化面、精神面での成長にとって大きな意義がある。発表では、学習者、教師だけでなく、教室内外の多くの人たちをつなぐことを可能にするオンラインツールについて紹介し、その効果的な使い方や交流を成功させるための具体的な提案も行う。

    Improving intercultural competence through online joint-seminars with university students from the U.S. and Sweden2015Conference paper (Refereed)
    Abstract [en]

    There have been quite a few studies regarding the development of intercultural competence through online exchanges (Helm 2009, Chun 2011, Schenker 2012, Kitade 2012, etc.). Most of these exchanges, however, are between native speakers and learners of that language. The benefit of such exchanges may be maximized if both parties are learning the same foreign language and have the opportunity to utilize the language they are learning during the interaction. As defined by Byram (1997) and Liaw (2006), 'intercultural competence' is not just learning about the target culture, but also about becoming aware of one's own culture, and connecting students from different countries who are studying the same target language and culture would be an ideal setting in order for the students to evaluate both their own and target cultures critically.

    It is often said to be difficult or almost impossible for students in distance courses to develop intercultural competence because of the lack of opportunity to study abroad or the lack of an international atmosphere in the classroom (Tyberg 2009). Thus another goal of this study is to investigate the possibility of providing opportunities for all students, regardless of their circumstances, to develop intercultural competence.

    During the spring semester 2012, a group of fourth level (intermediate to advanced level) Japanese students from Gettysburg College in the United States and from Högskolan Dalarna (Dalarna University) in Sweden took part in a study of how Japanese learners from different countries benefit from communicating with each other in Japanese. Throughout the term, the students exchanged ideas and views regarding the topics surrounding the issues of “identity” via blogs and joint-seminars using an online video conferencing system. The topic “identity” was selected since both parties can discuss the issue from different perspectives such as 'foreigners in Japan', 'foreigners in the U.S./Sweden', 'Japanese people living in the U.S./Sweden', as well as from the students' 'own identities.'

    The student survey showed that the students from both Sweden and the United States found the project to be fun, interesting and a new and positive experience. One student epitomized the comments from the majority of the participants. – “We were actively discussing identity with students raised in another culture in a class setting, which lends an air of understanding and interest to the discussion.”

    The results from this study suggest that through interactions with university students from other countries who study Japanese at the same level, the students can gain not only Japanese skills, but expand their horizons and deepen their understanding of another culture as well as the topics discussed during the meetings. Not everyone has an opportunity to study abroad, but today's technology allows every student to be a part of the internationalization process, develop his/her cultural-literacy and reflect on his/her identity.

    In this session, the process, benefits, and limitations of our online exchanges will be discussed and some suggestions on how one should conduct and what are required for in ordered to have a successful international online exchanges will also be presented based on our experiences.

    The target audience of this session are teachers and educators as well as administrators who recognize the importance of acquisition of intercultural competence, not limited to but especially, in language education, and those who are considering the possibilities of allowing students to participate in the internationalization process without traveling abroad.

    Who is the economic criminal? A comparison between countries and types of crime

    In white collar crime research two particularly competing definitions (Sutherland versus the Revisionists) have dominated the field during the last two decades. Sutherland’s definition states that the sociodemographic profile is homogeneous (entrepreneur with high education and high or regular income), despite type of white collar crime or context. The definition given by the Revisionists states that white collar criminals’ demographic profile is heterogeneous (everyone can be convicted for white collar crime). As a consequence of this divided definitional approach we have a contradictive outcome of who the white collar criminal is. Our purpose is to investigate the qualification of the two definitions by analyzing heterogeneity/ homogeneity based on crime type and national context. The investigation is based on seven countries from the EES 2004 (European Social Survey). We use four types of crime. The results show a rather homogeneous demographic profile but there is also a certain substantial heterogeneity depending on kinds of crime and context. The results altogether indicate that the Revisionists’ definition is more correct in its description of the white collar criminal than Sutherland’s definition. The demographic profile of the white collar criminal seems to be more complex than a profile confined to just one social category would be and the contextual factor has an impact on the variety of the demographic profile. An important task for future research is to hold the door open for further demographic investigations depending on the type of crime and country that the study is based on.

    An efficient algorithm for the pseudo likelihood estimation of the generalized linear mixed models (GLMM) with correlated random effects2009Report (Other academic)
    Abstract [en]

    This paper presents a two-step pseudo likelihood estimation technique for generalized linear mixed models with correlated random effects. The proposed estimation technique does not require reparametarisation of the model. Multivariate Taylor's approximation has been used to approximate the intractable integrals in the likelihood function of the GLMM. Based on the analytical expression for the estimator of the covariance matrix of the random effects, a condition has been presented as to when such a covariance matrix can be estimated through the estimates of the random effects. An application of the model with a binary response variable has been presented using a real data set on credit defaults from two Swedish banks. Due to the use of two-step estimation technique, proposed algorithm outperforms the conventional pseudo likelihood algorithms in terms of computational time.

    Abstract [en]

    This paper presents a two-step pseudo likelihood estimation technique for the generalized linear mixed models (GLMM) with random effects being correlated (possibly between subjects). Due to the use of the two-step estimation technique the proposed algorithm outperforms the conventional pseudo likelihood algorithms, e.g. Wolfinger and O’Connell (1993), in terms of computational time. Moreover, it does not require any reparametarisation of the model such as Lindstrom and Bates (1989). Multivariate Taylor’s approximation has been used to approximate the intractable integrals in the likelihood function of the GLMM. Based on the analytical expression for the estimator of the covariance matrix of the random effects, a condition has been presented as to when such a covariance matrix can be estimated through the estimates of the random effects. An application of the estimation technique with a binary response variable is presented using a real data set on credit defaults.

    Feasible computation of the generalized linear mixed models with application to credit risk modelling2010Doctoral thesis, monograph (Other academic)
    Abstract [en]

    This thesis deals with developing and testing feasible computational procedures to facilitate the estimation of and carry out the prediction with the generalized linear mixed model (GLMM) with a scope of applying them to large data sets. The work of this thesis is motivated from an issue arising in credit risk modelling. We have access to a huge data set, consisting of about one million observations, on credit history obtained from two major Swedish banks. The principal research interest involved with the data analysis is to model the probability of credit defaults by incorporating the systematic dependencies among the default events. In order to model the dependent credit defaults we adopt the framework of GLMM which is a popular approach to model correlated binary data. However, existing computational procedures for GLMM did not offer us the flexibility to incorporate the desired correlation structure of defaults events. For the feasible estimation of the GLMM we propose two estimation techniques being the fixed effects (FE) approach and the two-step pseudo likelihood approach (2PL). The preciseness of the estimation techniques and their computational advantages are studied by Monte-Carlo simulations and by applying them to the credit risk modelling. Regarding the prediction issue, we show how to apply the likelihood principle to carry out prediction with GLMM. We also provide an R add-in package to facilitate the predictive inference for GLMM.

    Feasible estimation of generalized linear mixed models (GLMM) with weak dependency between groups2010Manuscript (preprint) (Other academic)
    Abstract [en]

    This paper presents a two-step pseudo likelihood estimation technique for generalized linear mixed models with the random effects being correlated between groups. The core idea is to deal with the intractable integrals in the likelihood function by multivariate Taylor's approximation. The accuracy of the estimation technique is assessed in a Monte-Carlo study. An application of it with a binary response variable is presented using a real data set on credit defaults from two Swedish banks. Thanks to the use of two-step estimation technique, the proposed algorithm outperforms conventional pseudo likelihood algorithms in terms of computational time.

    Industry shocks and empirical evidences on defaults comovement2009Report (Other academic)
    Abstract [en]

    It is commonly agreed that the credit defaults are correlated. However, the mechanism of such dependence is not yet fully understood. This paper contributes to the current understanding about the defaults comovement in the following way. Assuming that the industries provides the basis of defaults comovement it provides empirical evidence as to how such comovements can be modeled using correlated industry shocks. Generalized linear mixed model (GLMM) with correlated random effects is used to model the defaults comovement. Empirical evidences are drawn through analyzing individual borrower level credit history data obtained from two major Swedish banks between the period 1994-2000. The results show that the defaults are correlated both within and between industries but not over time (quarters). A discussion has also been presented as to how a GLMM for defaults correlation can be explained.

    Likelihood prediction for generalized linear mixed models under covariate uncertainty2014In: Communications in Statistics - Theory and Methods, ISSN 0361-0926, E-ISSN 1532-415X, Vol. 43, no 2, p. 219-234Article in journal (Refereed)
    Abstract [en]

    This paper presents the techniques of likelihood prediction for the generalized linear mixed models. Methods of likelihood prediction is explained through a series of examples; from a classical one to more complicated ones. The examples show, in simple cases, that the likelihood prediction (LP) coincides with already known best frequentist practice such as the best linear unbiased predictor. The paper outlines a way to deal with the covariate uncertainty while producing predictive inference. Using a Poisson error-in-variable generalized linear model, it has been shown that in complicated cases LP produces better results than already know methods.

    Computionally feasible estimation of the covariance structure in generalized linear mixed models2008In: Journal of Statistical Computation and Simulation, ISSN 0094-9655, E-ISSN 1563-5163, Vol. 78, no 12, p. 1229-1239Article in journal (Refereed)
    Abstract [en]

    In this paper, we discuss how a regression model, with a non-continuous response variable, which allows for dependency between observations, should be estimated when observations are clustered and measurements on the subjects are repeated. The cluster sizes are assumed to be large. We find that the conventional estimation technique suggested by the literature on generalized linear mixed models (GLMM) is slow and sometimes fails due to non-convergence and lack of memory on standard PCs. We suggest to estimate the random effects as fixed effects by generalized linear model and to derive the covariance matrix from these estimates. A simulation study shows that our proposal is feasible in terms of mean-square error and computation time. We recommend that our proposal be implemented in the software of GLMM techniques so that the estimation procedure can switch between the conventional technique and our proposal, depending on the size of the clusters.

    Utvärdering av det arbetsmarknadspolitiska projektet "Volvo Cars och dess underleverantörer"2012Report (Other academic)
    Abstract [sv]

    Denna rapport är en utvärdering av det arbetsmarknadspolitiska projektet "Volvo Cars och dess underleverantörer", som har genomförts av Arbetsförmedlingen i samarbete med Skolverket och Svenska ESF-rådet. Den 5 juni 2009 ansökte Sveriges regering om medel hos den Europeiska globaliseringsfonen (EGF)2 för att kunna erbjuda åtgärder för personer som blivit uppsagda från Volvo Cars AB och dess underleverantörer. Syftet med projektet var att kunna erbjuda de som blivit uppsagda kompetensutveckling, nya yrkeskunskaper och möjlighet att etablera egna företag.

    På operativ nivå drevs projektet i samverkan mellan Arbetsförmedlingen och den kom-munala yrkesvuxenutbildningen ("Yrkesvux"). Yrkesvux i Göteborgs kommun fick i upp-drag av Skolverket att samordna den del av verksamheten som berörde kommunal yr-kesvuxenutbildning. Projektet startade 1 januari 2010 och avslutades 31 maj 2011. Enligt kommissionens beslut fick medel även användas retroaktivt för insatser som hade givits till de uppsagda i form av olika arbetsmarknadsutbildningar, det s.k. snabbspåret, under 2009 innan projektet hade startat.

    Av nästan 5 000 individer i målgruppen som registrerade sig vid Arbetsförmedlingen del-tog knappt en fjärdedel i projektets insatser (exkl. vägledning). Av dessa gick 55 procent i aktiviteter enbart genom Arbetsförmedlingen, 37 procent enbart genom Yrkesvux och åtta procent genom både Arbetsförmedlingen och Yrkesvux. De vanligaste förekommande utbildningsinriktningarna var industri och bygg, fordonsindustri, transport och magasine-ring, omvårdnad och handel.

    Har kommunala sommarjobb under gymnasieåren en positiv effekt på arbetskarriären senare i livet?2013Report (Other academic)
    Abstract [sv]

    Att erbjuda sommarjobb till ungdomar ses i många länder som ett sätt att förbättra ungdomars möjligheter att komma in och etablera sig på arbetsmarknaden. I Sverige erbjuder de flesta kommuner, delvis finansierat med statliga medel, sommarjobb till ungdomar. Den forskning som finns kring effekten av sommarjobb för ungdomar pekar dock i olika riktningar och lider ofta av metodproblem. Vi undersöker här med bättre metodologiska förutsättningar om kommunala sommarjobb för gymnasieungdomar i Falu kommun har någon positiv effekt på den postgymnasiala inkomstutvecklingen. Vi följer 2 650 ungdomar som, under första året i gymnasiet, ansökte om kommunalt sommarjobb. Vi följer dem tills de når en ålder av som mest 29 år. De kommunala sommarjobben fördelades genom ett lotteriförfarande där alla som ansökte hade lika stor chans att bli tilldelad ett sommarjobb. Vi finner ingen programeffekt för män. För kvinnor upptäcker vi en positiv effekt och då speciellt för kvinnor med låga betyg från grundskolan.

    High-School Students´ Summer Jobs and their Ensuing Labor Market Achievement: the Long Term Effect2013Report (Other academic)
    Abstract [en]

    In part because of high and persistent youth unemployment, adolescent students’ transition from school to work is an important policy and research topic. Many countries have implemented public programs offering summer jobs or work while in high-school as measures to smooth the transition. While the immediate effect of the programs on school attendance, school grades, and disposable income is well documented, their effect on the transition to the labor market remains an open question. Observational studies have shown strong positive effects of summer jobs, but also that the estimated effect is highly vulnerable to selection bias. In this paper, some 3700 high-school students applying for summer jobs in the period 1995-2003,via a program, are followed to 30 years of age. A quarter of the applicants were randomly offered a summer job each year. Among the remaining students, 50% had a (non-program related) summer job while in high-school. We find the income, post high-school, for the offered and non-offered groups to be similar and conclude that the effect of summer jobs on the transition to the labor market is inconsequential.

    Sommarjobb, arbetslivserfarenhet och framtida arbetsinkomst2015In: Arbetsmarknad & Arbetsliv, ISSN 1400-9692, Vol. 21, no 4, p. 26-40Article in journal (Refereed)
    Abstract [sv]

    De flesta kommuner erbjuder sommarjobb till gymnasieungdomar. Vi har undersökt om denna arbetslivserfarenhet påverkar flickors framtida arbetsinkomster. Vi följde 1 447 flickor i fem till tolv år efter avslutat gymnasium. Flickorna hade under sitt första gymnasieår ansökt och slumpmässigt tilldelats sommarjobb av Falu kommun. Effekten av sommarjobbserfarenheten var positiv och betydande för dem.

    The effect of summer jobs on post-schooling incomes2013Report (Other academic)
    Abstract [en]

    In part because of high youth unemployment, students’ transition from school to work is an important policy and research topic. Public programs offering summer jobs or work while in high school as measures to smooth the transition is commonplace. The immediate effect of the programs on school attendance, school grades, and disposable income is well documented. However, their effect on the transition to the labor market remains unsettled, partly because of a potential selection bias in previous observational studies. In this paper, 2650 first graders of high school in Falun Council, Sweden, randomly allotted summer jobs via a program in the years of 1997-2003, are followed ten years after graduation. The program led to a substantially larger accumulation of work experience while in high school for offered (particularly weak academically performing) females, but not for offered males. Hence, the immediate program effect was heterogeneous. Females were used to estimate the causal effect of work experience while in high school on post-schooling incomes. The (statistically) significant estimate implies an elasticity of 0.4. Work experience while in high school seems to be of future benefit, but the elasticity is potentially inflated due to heterogeneous effects that we were unable to account for.

    The program and treatment effect of summer jobs on girls’ post-schooling incomes2014Report (Other academic)
    Abstract [en]

    Public programs (of disputed effect) offering summer jobs or work while in high school to smooth the transition from school to work is commonplace. In this paper, 1447 girls in their first grade of high school between 1997-2003 and randomly allotted summer jobs via a program in Falun (Sweden) are followed 5-12 years after graduation. The program led to a substantially larger accumulation of income while in high school. The causal effect of the high school income on post-schooling incomes was substantial and statistically significant. The implied elasticity of 0.4 is however potentially inflated dueto heterogeneous effects.
