High-School Students´ Summer Jobs and their Ensuing Labor Market Achievement : the Long Term Effect

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.

The Optimal trigger speed of vehicle activated signs

The thesis aims to elaborate on the optimum trigger speed for Vehicle Activated Signs (VAS) and to study the effectiveness of VAS trigger speed on drivers’ behaviour. Vehicle activated signs (VAS) are speed warning signs that are activated by individual vehicle when the driver exceeds a speed threshold. The threshold, which triggers the VAS, is commonly based on a driver speed, and accordingly, is called a trigger speed. At present, the trigger speed activating the VAS is usually set to a constant value and does not consider the fact that an optimal trigger speed might exist. The optimal trigger speed significantly impacts driver behaviour. In order to be able to fulfil the aims of this thesis, systematic vehicle speed data were collected from field experiments that utilized Doppler radar. Further calibration methods for the radar used in the experiment have been developed and evaluated to provide accurate data for the experiment. The calibration method was bidirectional; consisting of data cleaning and data reconstruction. The data cleaning calibration had a superior performance than the calibration based on the reconstructed data. To study the effectiveness of trigger speed on driver behaviour, the collected data were analysed by both descriptive and inferential statistics. Both descriptive and inferential statistics showed that the change in trigger speed had an effect on vehicle mean speed and on vehicle standard deviation of the mean speed. When the trigger speed was set near the speed limit, the standard deviation was high. Therefore, the choice of trigger speed cannot be based solely on the speed limit at the proposed VAS location. The optimal trigger speeds for VAS were not considered in previous studies. As well, the relationship between the trigger value and its consequences under different conditions were not clearly stated. The finding from this thesis is that the optimal trigger speed should be primarily based on lowering the standard deviation rather than lowering the mean speed of vehicles. Furthermore, the optimal trigger speed should be set near the 85th percentile speed, with the goal of lowering the standard deviation.

Entry, re-location and growth in the Swedish wholesale trade industry

Wholesale trade has an intermediate position between manufacturing and retail in the distributional channel. In modern economies, consumers buy few, if any, products directly from manufacture or producer. Instead, it is a wholesaler, who is in direct contact with producers, buying goods in larger quantities and selling them in smaller quantities to retailers. Traditionally, the main function of a wholesaler has been to push goods along the distributional channel from producer to retailer, or other nonend user. However, the function of wholesalers usually goes beyond the process of the physical distribution of goods. Wholesalers also arrange storage, perform market analyses, promote trade or provide technical support to consumers (Riemers 1998). The existence of wholesalers (and other intermediaries) in the distributional channel is based on the effective and efficient performance of distribution services, that are needed by producers and other members of the supply chain. Producers usually do not enjoy the economies of scale that they have in production, when it comes to providing distributional services (Rosenbloom 2007) and this creates a space for wholesalers or other intermediaries. Even though recent developments in the distributional channel indicate that traditional wholesaling activities now also compete with other supply chain organizations, wholesaling still remains an important activity in many economies (Quinn and Sparks, 2007). In 2010, the Swedish wholesale trade sector consisted of approximately 46.000 firms and generated an annual turnover of 1 300 billion SEK (Företagsstatistiken, Statistics Sweden). In terms of turnover, wholesaling accounts for 20% of the gross domestic product and is thereby the third largest industry. This is behind manufacturing and a composite group of firms in other sectors of the service industry but ahead of retailing. This indicates that the wholesale trade sector is an important part of the Swedish economy. The position of wholesaling is further reinforced when measuring productivity growth. Measured in terms of value added per employee, wholesaling experienced the largest productivity growth of all industries in the Swedish economy during the years 2000 through 2010. The fact that wholesale trade is one of the important parts of a modern economy, and the positive development of the Swedish wholesale trade sector in recent decades, leads to several questions related to industry dynamics. The three topics that will be examined in this thesis are firm entry, firm relocation and firm growth. The main question to be answered by this thesis is what factors influence new firm formation, firm relocation and firm growth in the Swedish wholesale trade sector?

Samhällets roll i besöksnäringens utveckling

Studien föranleds av den nya konkurrenslagstiftningen som påverkar gränsdragningen mellan privat och offentligt engagemang inom turismen. I studien görs ett försök att förstå den historiska utvecklingen utifrån institutionell teori. Att över tid följa hur turismen från att ha legat utanför samhällets intressesfär till att i allt högre grad inkluderas i och bli föremål för samhällsåtaganden till att i betydande utsträckning åter överflyttas till den privata sfären blir enligt författarnas mening begripligare om förändringsförloppet förstås i den referensram som den institutionella teorin erbjuder. Den pendelrörelse som på detta sätt kan urskiljas beträffande gränsdragningen mellan privat och offentligt är också en del i hur man skall förstå hur synen på konkurrensbetingelser inte är statisk utan i hög grad konstruerad och framförhandlad från tid till annan. Men det som gälller tid tycks också ha en geografisk dimension där vad som anses tillåtet i en del av landet inte uppfattas så på ett annat ställe. Det som uppfattas som ett juridiskt spörsmål i förstone vilar i realiteten i en komplex kontext med ingredienser av historia, ekonomi och geografi.

Coachande ledarskap : En utvärdering av genomförd ledarutveckling inom Borlängekommun

This is a thesis in Personal- och Arbetslivsprogrammet at Dalarna University with thepurpose of evaluating an education initiative in Borlänge kommun. The educationCoaching Leadership is an initiative for the managers in the organization to exercisegood leadership and the education also serves as an incentive for managers. Eightbusiness managers and one from the HR staff have completed the training. Out of thetotal 9 participants in the training, six of them took part in this evaluation. Based on thethesis aim and questions we wanted to explore participants' attitudes to the education,and what skills and abilities they have acquired on the basis of educational goals andcontent. To obtain results, a semi-structured interview methodology was used, this inorder to get answers to predefined questions while the participants would have theopportunity to give an as broad picture as possible.The result of this evaluation demonstrates that the participants are in favor of trainingand they've got the tools, knowledge and ability to apply coaching in their job role,which was included in the educational goals. For the CL-education to promote theorganization's development potential, the participants mentions that it takes time totrain and that employees must have the knowledge of the organization's educationaldirection.

Flexibilitetens frammarsch, en studie om den intermittenta anställningen

Flexible working conditions is used extensively in organizations today as a way to create flexibility for the employer. Recently we’ve been reading in the newspapers that this approach is a growing problem and the EU has warned Sweden twice that abuse of these forms of employment must be stopped. The Government has recently submitted a proposed rule change to reduce the possibility of stacking one temporary contract after another. Borlänge kommun makes themselves more flexible with the intermittent employments. This study aims to examine why infrequent employments, such as the intermittent employment is used and preferred by Borlänge kommun and how it’s perceived by affected employees in the organization. The questions related, besides why the intermittent employment is used by the organization and how its perceived by those involved, also includes the management of intermittent employment and how the organization is handling work contracts. The background information on the employment law implications gives the reader an insight into how the regulatory framework works surrounding the topic. The theory section highlights the main theories about flexibility and its different shapes and perspectives. For the study a qualitative approach is used. A case study with semi-structured interviews was performed. The respondents were employees involved in the staffing of intermittent employees and also members of the staff with an intermittent employment. The results show that the employment and contracts is correctly handled by labour law regulations. This study shows that Borlänge kommun uses intermittent employments extensively, with its 1 320 intermittently employees. If this is abuse, or not, is not clear from the result. The authors discuss, however, if that is the case. The intermittent employment is used mainly because of the great needs. This is because society is changing and the average age is increasing, both by those using the services and the employees. All respondents perceive the intermittent employment as most flexible for the employees. Respondents working in the staffing department say that they are not flexible enough. The intermittent employees’ working today does not cover the great need. Borlänge kommun think that the flexibility should benefit them more and is currently trying to become more flexible. The employees were generally satisfied with their work situation. Some tendencies of insecurity and uncertainty could be inferred from the intermittent employees answers. The author’s conclusions are that flexibility and the intermittent employment contracts mainly benefit the employer and the employees who actively choose this type of work, such as students. This kind of employment affects, however, the society and those who need a secure lifestyle. The necessary permanent contracts are becoming fewer and replaced by precarious and flexible employment conditions.

Det handlar om kärlek : En fallstudie av ett projekt för att synliggöra barns rättigheter för ungdomar i årskurs 7-9

Föreliggande studie har projektet Det handlar om kärlek i fokus. Det är ett projekt i Rädda Barnens regi som tar sin utgångspunkt i Barnkonventionen och mänskliga rättigheter. Projek-tet har genomförts med medel från Länsstyrelsen Dalarna på tre skolor i Dalarna. Denna stu-die rör dock endast Maserskolan i Borlänge kommun. Målgruppen är årskurs 7-9. Syftet är att förebygga hedersrelaterat våld och förtryck, något som emellertid inte uttrycks officiellt, då en del i projektidén är att inte någon ska känna sig utpekad. Man kan diskutera att ha ett un-derliggande syfte som finns med i det material som skolans ledning får ta del av, men som inte delges eleverna. De vuxna som varit involverade i projektet har dock inte sett detta som så problematiskt. De framhåller att den komplexitet som omger elever som lever i hederskulturer i sitt privatliv och som samtidigt i sitt offentliga liv ständigt konfronteras med en helt annorlunda samhällskultur, skapar en situation som måste hanteras på specifika sätt och att detta förfarande föll väl ut för elevernas del. Detta sågs som det väsentliga i den här projekt-idén. Studiens underlag har insamlats via triangulering, vilket innebär att flera olika metoder använts. I detta fall observation vid olika aktiviteter inom projektets ram, informella samtal, elevenkäter och intervjuer. Resultatet visar att projektidén fungerade väl med avseende på dess intentioner och syfte. Eleverna fick ökade kunskaper om barns och ungas rättigheter och majoriteten av eleverna visade intresse och engagemang i de aktiviteter som genomfördes. Skolan som en viktigt arena för att sprida kunskap om mänskliga rättigheter synliggjordes.

Essays on firm dynamics in the Swedish wholesale trade sector

This thesis consists of a summary and five self-contained papers addressing dynamics of firms in the Swedish wholesale trade sector. Paper [1] focuses upon determinants of new firm formation in the Swedish wholesale trade sector, using two definitions of firms’ relevant markets, markets defined as administrative areas, and markets based on a cost minimizing behavior of retailers. The paper shows that new entering firms tend to avoid regions with already high concentration of other firms in the same branch of wholesaling, while right-of-the-center local government and quality of the infrastructure have positive impacts upon entry of new firms. The signs of the estimated coefficients remain the same regardless which definition of relevant market is used, while the size of the coefficients is generally higher once relevant markets delineated on the cost-minimizing assumption of retailers are used. Paper [2] analyses determinant of firm relocation, distinguishing between the role of the factors in in-migration municipalities and out-migration municipalities. The results of the analysis indicate that firm-specific factors, such as profits, age and size of the firm are negatively related to the firm’s decision to relocate. Furthermore, firms seems to be avoiding municipalities with already high concentration of firms operating in the same industrial branch of wholesaling and also to be more reluctant to leave municipalities governed by right-of-the- center parties. Lastly, firms seem to avoid moving to municipalities characterized with high population density. Paper [3] addresses determinants of firm growth, adopting OLS and a quantile regression technique. The results of this paper indicate that very little of the firm growth can be explained by the firm-, industry- and region-specific factors, controlled for in the estimated models. Instead, the firm growth seems to be driven by internal characteristics of firms, factors difficult to capture in conventional statistics. This result supports Penrose’s (1959) suggestion that internal resources such as firm culture, brand loyalty, entrepreneurial skills, and so on, are important determinants of firm growth rates. Paper [4] formulates a forecasting model for firm entry into local markets and tests this model using data from the Swedish wholesale industry. The empirical analysis is based on directly estimating the profit function of wholesale firms and identification of low- and high-return local markets. The results indicate that 19 of 30 estimated models have more net entry in high-return municipalities, but the estimated parameters is only statistically significant at conventional level in one of our estimated models, and then with unexpected negative sign. Paper [5] studies effects of firm relocation on firm profits of relocating firms, employing a difference-in-difference propensity score matching. Using propensity score matching, the pre-relocalization differences between relocating and non-relocating firms are balanced, while the difference-in-difference estimator controls for all time-invariant unobserved heterogeneity among firms. The results suggest that firms that relocate increase their profits significantly, in comparison to what the profits would be had the firms not relocated. This effect is estimated to vary between 3 to 11 percentage points, depending on the length of the analyzed period. 

Extended local labor markets due to high speed trains : Visualization of estimations in the Swedish national travel demand forecasting tool, SAMPERS

Wider economic benefits resulting from extended geographical mobility is one argument for investments in high-speed rail. More specifically, the argument for high-speed trains in Sweden has been that they can help to further spatially extend labor market regions which in turn has a positive effect on growth and development. In this paper the aim is to cartographically visualize the potential size of the labor markets in areas that could be affected by possible future high-speed trains. The visualization is based on the forecasts of labor mobility with public transport made by the Swedish national mobility transport forecasting tool, SAMPERS, for two alternative high-speed rail scenarios. The analysis, not surprisingly, suggests that the largest impact of high-speed trains results in the area where the future high speed rail tracks are planned to be built. This expected effect on local labor market regions of high-speed trains could mean that possible regional economic development effects also are to be expected in this area. However, the results, in general, from the SAMPERS forecasts indicaterelatively small increases in local labor market potentials.

How does employment density influence individuals’ wages? : A micro data approach.

We estimate the effect of employment density on wages in Sweden in a large geocoded data set on individuals and workplaces. Employment density is measured in four circular zones around each individual’s place of living. The data contains a rich set of control variables that we use in an instrumental variables framework. Results show a relatively strong but rather local positive effect of employment density on wages. Beyond 5 kilometers the effect becomes negative. This might indicate that the effect of agglomeration economies falls faster with distance than the effects of congestion.

Road network and GPS tracking with data processing and quality assessment

GPS technology has been embedded into portable, low-cost electronic devices nowadays to track the movements of mobile objects. This implication has greatly impacted the transportation field by creating a novel and rich source of traffic data on the road network. Although the promise offered by GPS devices to overcome problems like underreporting, respondent fatigue, inaccuracies and other human errors in data collection is significant; the technology is still relatively new that it raises many issues for potential users. These issues tend to revolve around the following areas: reliability, data processing and the related application. This thesis aims to study the GPS tracking form the methodological, technical and practical aspects. It first evaluates the reliability of GPS based traffic data based on data from an experiment containing three different traffic modes (car, bike and bus) traveling along the road network. It then outline the general procedure for processing GPS tracking data and discuss related issues that are uncovered by using real-world GPS tracking data of 316 cars. Thirdly, it investigates the influence of road network density in finding optimal location for enhancing travel efficiency and decreasing travel cost. The results show that the geographical positioning is reliable. Velocity is slightly underestimated, whereas altitude measurements are unreliable.Post processing techniques with auxiliary information is found necessary and important when solving the inaccuracy of GPS data. The densities of the road network influence the finding of optimal locations. The influence will stabilize at a certain level and do not deteriorate when the node density is higher.

Heuristic optimization of the p-median problem and population re-distribution

This thesis contributes to the heuristic optimization of the p-median problem and Swedish population redistribution.   The p-median model is the most representative model in the location analysis. When facilities are located to a population geographically distributed in Q demand points, the p-median model systematically considers all the demand points such that each demand point will have an effect on the decision of the location. However, a series of questions arise. How do we measure the distances? Does the number of facilities to be located have a strong impact on the result? What scale of the network is suitable? How good is our solution? We have scrutinized a lot of issues like those. The reason why we are interested in those questions is that there are a lot of uncertainties in the solutions. We cannot guarantee our solution is good enough for making decisions. The technique of heuristic optimization is formulated in the thesis.   Swedish population redistribution is examined by a spatio-temporal covariance model. A descriptive analysis is not always enough to describe the moving effects from the neighbouring population. A correlation or a covariance analysis is more explicit to show the tendencies. Similarly, the optimization technique of the parameter estimation is required and is executed in the frame of statistical modeling.
