This thesis analyzes the political discourse on skilled labour migration in Germany between 2005 and 2009 and investigates how and why skilled labour migration polices are negotiated in the Federal Republic of Germany. In particular the thesis highlights the significance of underlying policy maker motives within the policy formation process of Germany s 2009 Action Programme on Skilled Labour Migration as well as their ultimate imprint on the legislation. The critical discourse analysis of parliamentary debate in Germany between 2005 and 2009 in conjunction with interviews with relevant national policy makers, institutional actors, labour market stakeholder, and independent policy advisors reveals that there is a significant discrepancy between policy maker intent in regards to skilled labour migration legislation and the stated intent of the 2009 Action Programme. While the stated aim of the Action Programme is to facilitate and promote skilled labour migration to Germany, the analysis of relevant political debate and the stakeholder interviews reveals that German policy makers are primarily motivated to protect and promote preferential labour market access for domestic workers while at the same time restricting undesired labour migration to Germany. As a result, the policy measures of the 2009 Action Programme on Skilled Labour Migration have a strong protectionist and restrictionist emphasis. Moreover, the thesis reveals that the complex and multilayered power-negotiations over skilled labour migration legislation between the various policy makers, institutional actors, and labour market stakeholders are largely shaped and framed by domestic political considerations. Notwithstanding the widely acknowledged global competition over skilled workers and the need for German labour market to maintain competitive within the global economy, immigration policy makers in Germany are primarily motivated by factors that are firmly embedded within the national political sphere and that aim to control, limit, and restrict territorial access of foreign workers into the national labour market. This in turn highlights the need for migration scholars to reposition and re-conceptualize the role of the nation-state and as an active agent in shaping international labour migration flows.

We empirically investigate the importance of centrality (holding a central position in a spatial network) for strategic interaction in pricing for the Austrian retail gasoline market. Results from spatial autoregressive models suggest that the gasoline station located most closely to the market center - defined as the 1-median location - exerts the strongest effect on pricing decisions of other stations. We conclude that centrality influences firms' pricing behavior and further find that the importance of centrality increases with market size.

The objective of this thesis is to investigate and describe components of pricing system which influence the dynamic performance of a price leader manufacturing firm in an oligopoly capital intensive industry producing an identical intermediate product (s). The synthetic fibre industry is chosen as an illustrative case upon which the discussion is built. However, this work could generally be applied to a wide variety of organizations and situations. After discussing the suitability of system dynamics to the formulation of long-run pricing strategy, a model of the pricing system is constructed by using this technique. The behaviour of this system is examined in terms of feedback loops. That is to illustrate how the characteristics of these loops and the interaction among them affect the dynamic behaviour of the system, and how this behaviour can be improved via changing the components of these loops and/or their structures. The improved system is simulated under different external disturbances, certain parameter changes, and different pricing control policies. The simulation shows that the design of a set of robust pricing policies makes the system insensitive to external disturbance and error in parameters. It also shows that the ability of the firm to attain its growth and profitability objectives is affected by the chosen control pricing policies. Some potential applications of the model, particularly, as planning and training tools are highlighted. It is concluded that System Dynamics is an appropriate approach to the formulation of the long-run pricing strategies.

Guatemala, the most populous country in Central America, is haunted by the legacy of violence, political instability, poverty, corruption, and persisting, relentless inequality. Narco-trafficking routes through Central America became firmly established after air- and sea-based routes were disrupted by U.S. and Mexican drug enforcement efforts in the 1990s. Guatemala and its Central American neighbors were highly vulnerable to incursion by the drug trade, ideally-located between production sources and major consumers, its people and governments weakened by long-standing armed conflict. Evidence shows the drug trade disproportionately impacts Guatemala in comparison to the rest of the region. Its neighbors share similarly well-located geography and the legacy of armed conflicts, but Guatemala lacks the institutional strength and ability to combat the cartels. This paper posits that U.S. prohibitionist policies are ineffective and harmful to Guatemala’s people, based on a supply-reduction model and a review of previous literature and anecdotal evidence. Narco-trafficking and the United States’ drug enforcement efforts, strategies and policies, intensify existing violence, poverty, inequality and corruption within Guatemala, ensnaring its people in a recurring cycle of violence which reinforces barriers to escaping poverty and crime.

In the first paper, using a dataset of the records of Texas Real Estate Agents, I reexamine the findings of Hsieh and Moretti (2003) regarding the inefficiency of free entry in real estate industry: first, I point out one important source of misidentification in that paper's analysis of the relationship between home prices and the number of real estate agents in a city. This misidentification stems from not including the ratio of houses sold in a city to its labor force size as an explanatory variable. Failure to account for this variable will result in inflated coefficient for the effect of home prices on the percentage of real estate agents in a city's labor force. Second, I analyze the effect of home prices on productivity of real estate agents. Empirical evidence supports theory prediction of inverse relationship between home prices and productivity of its real estate agents (measured as the number of houses sold per agent) and the empirical results in Hsieh and Moretti (2003). Third, I investigate the relationship between the extra wages of real estate agents (defined as average earning net of agents' outside option) and home prices in a city. In support for free entry, I find no evidence of any such relationship. In theory, free entry potentially leads to social inefficiency. This paper finds strong empirical evidence consistent with excess entry into Texas Residential Real Estate Brokerage Industry and studies the effects of heterogeneity and future uncertainty on such inefficiencies. I develop a dynamic model of entry and exit with heterogeneous agents and modify the predictions of the earlier literature. I show that the heterogeneity among (real estate) agents results in a weaker relationship between the real estate commission fees and the number of real estate agents. I also show that the models developed for static cases in the previous papers are special cases of the more general model in this paper. The model allows us to explain the lower business stealing effect compared to static and homogeneous models that is observed in the data. To address the issue of excess entry, I separate the business stealing effect from demand driven entry and find that on average 75 percent of entry is due to business stealing. To evaluate free entry, I control for agents' outside options and find that the extra wages of the real estate agents do not vary with housing prices. The objective of the third paper is to study the determinants of commission rates in the two-sided market of real estate brokerage industry and explain the emergence of the MLS and its impact on commission rates. In addition to their commission rates, real estate agencies decide on their MLS policies as well: they can either list the property with the MLS and share information about it, or not list the property with the MLS. If a property is listed with the MLS, all MLS subscribers can see the listing and send their potential buyers to see that property. Potential buyers can go to any agency to purchase such a property. If the property is \textit{not} listed with the MLS, to buy a house, a buyer must go to the same agency that the seller has signed up with. Since sellers pay the commission fees, and buyers no longer have to go to the same agency, with MLS listing, buyers choose the closest agency regardless of the commission rates charged by the agencies. Therefore, changes in the commission rates only change the affiliation of the sellers and not that of the buyers. This leads to a softer competition under MLS listing as agencies compete only in the seller side of the market. The softer competition and resulting higher commission rates are desirable to the agencies. They prefer the MLS listing outcome and given the optimal strategies after observing each other's listing decisions, agencies weakly prefer listing to no listing. I show that the one period game has two Nash Equilibria in which either both real estate agencies choose to list their houses with the MLS, or both decide not to list their houses with the MLS. The no listing equilibrium forces buyers to work through that agency's agents and effectively ties the both sides of the market. The higher commission rate equilibrium of the game allows buyers to choose either agency and reduces the competition to the sellers side. Softer competition in turn, results in higher equilibrium commission rates and higher profits along the equilibrium path. / text

<p>This thesis deals with how companies utilize their enterprise systems in their business relationships. The study’s starting point is enterprise systems that basically are standardised information systems that the company can acquire from software vendors like SAP, Oracle and Microsoft. Enterprise systems aim to integrate and manage all the company’s data and it can also be linked to its business partners.</p><p>The thesis contains two case studies of how a focal company utilizes its enterprise system in their business relationships. To accomplish this, an analytical framework based upon the combination of an information systems (IS) and a business relationship perspective is developed and applied. The IS perspective follows an ‘ensemble view of technology’ approach which describes the use of information systems as embedded in a both technical and social context. The business relationship perspective is founded in empirical studies of industrial companies. Basically, business relationships are unique and based on the companies’ exchanges. It also involves behavioural elements as trust, commitment, adaptations and interdependencies between the partners.</p><p>The two case studies cover the business relationships between ten companies and the character of the studied business relationships varies. The results show that enterprise systems are mainly focused on the companies’ internal activities. The exchanges in the business relationships are either carried out without the enterprise system or are supported by some complementary information system. Enterprise systems are thus mainly seen as production systems. This can be explained by the heritage from former material and resource planning (MRP) systems. An alternative explanation can be that business relationships are unique and require continuous adaptations and a mutual orientation. Enterprise systems require structural data rendering them difficult to use for the activities of a business relationship. The users then develop other, individual, applications that handle what is needed in their ongoing business. The threat is that information can be lost on a company level. The challenge is therefore to investigate the complementary information systems functions to see if it is possible to extend the enterprise system to include them. To be worth its epithet, the enterprise system must facilitate all the business activities found in the companies business relationships.</p>

<p>This thesis examines the influence of investor protection and legal origin on equity market size. Previous studies have shown a relationship between legal origin and equity markets as well as quality of law. We examine whether there are any relationship between stock market capitalization as a percentage of GDP, private property rights, anti director rights and legal origin.</p><p>We use data from 49 countries in our sample that is collected from the World Bank, Heri-tage foundation and La Porta et al. (1998). Our study is based upon a cross-sectional re-gressions and a variance analyzes.</p><p>Our results show that property rights as well as anti director rights have a positive relation-ship to stock market capitalization as a percentage of GDP. We could not find any signifi-cant results in our regressions that stock market capitalization as a percentage of GDP can be explained by legal origin.</p><p>We consider previous conducted studies regarding legal origin to have exaggerated legal origins’ impact on equity markets. Equity markets are more related to the level of develop-ment in countries, no matter legal origin.</p>

Freight transportation is an integral element of various supply chains and has a complex and dynamical interrelationship with human economic activities. Modern logistical strategies paved way to the current supply chain organisation and logistics network design resulting in a more global economy and huge economies of scale. Recent trends of volatility of oil price have major implications in the movement of commodities across the supply chains. Likewise, climate change issues have presented urgent challenges in reducing carbon emissions for the transport and logistics sector. Pressure on the sector comes from both governments and consumers alike, demanding future sustainability as well as corporate environmental and social responsibility. The original contribution of this research is to investigate the system-wide dynamics of freight transportation and production in the context of supply chains. A theoretical framework called the ‘Geographic Adaptive Potential’ or GAP is built to understand how constraints in energy and emissions affect the production and distribution of commodities. The changes in the supply chain were investigated in four different components, namely a) the potential to shift to less energy and emissions intensive modes for long-haul freight, b) logistical strategies in the last leg of the chain or urban freight and c) local production and distribution, and d) the accessibility of potential customers to the markets. The design of the GAP components is in correspondence with the links of the supply chain. The analyses yielded an evaluation of the adaptive capacity of the freight transport and production system. For long-haul freight, a GIS-based model was created called the ‘New Zealand Intermodal Freight Network’ or NZIFN. It is an optimisation tool integrating the road, rail and shipping network of New Zealand and calculates that minimum time, operating costs, energy and emissions routes between 2 given locations. The case studies of Auckland to Wellington and Auckland to Christchurch distributions of non-perishable products established that even a marginal increase of rail and coastal shipping share produced around 10% reduction in both freight energy and greenhouse gas emissions. In the study of the last leg of the supply chain, the truck trip generation rates of different food stores were investigated. The strongest factors influencing the trip rates to a store are its size and product variation, the latter being a new parameter introduced in the dissertation. It is defined as the total number of brands for 6 chosen commodities commonly found in the stores. The trip rates together with the truck type and distance travelled were used to compute the freight energy usage of the stores. Results revealed that supermarkets consume the most energy for their delivery operations but relative to its physical size, they are more energy efficient than smaller stores. This is due to the utilisation of advanced logistical strategies such as freight consolidation and the effective use of distribution centres. The localised production chapter was explored in the context of Farmers’ markets and their difference with the conventional supermarket distribution system. Using a freight transport energy audit, the energy intensities of both systems were compared. The findings showed that Farmers’ markets were more energy-intensive than supermarkets owing to the low volumes of goods delivered to the market and the lack of freight consolidation effort in the system. The study on the active mode access of potential customers to both Farmers’ markets and supermarkets captured the interplay between freight and personal transport and is the final component of GAP. The results of the ArcGIS based model called ‘Active Mode Access’ or AMA demonstrated that both Farmers’ markets and supermarkets have the same level of accessibility for walking or biking customers. However, the calculations also showed that almost 87% of New Zealanders have no AMA to stores and are at risk for fuel price increase. Finally, the key result of this dissertation is the assessment that there is actually limited adaptive capacity of the freight transport and production system. This is due to network infrastructure and geographical constraints as well as commodity type and mode compatibility and other operational concerns. Due to these limitations, the GAP model assessed that reduction in energy and allowable emissions will ultimately reduce the amount of commodities moved in the system.

Problem statement Previous studies have indicated that poverty can be reduced through selling products to the poor. Moreover, these markets contain a large potential for profit that is currently untapped. Reaching these however requires substantial innovativeness and many companies have tried and failed. Surprisingly then, little theoretical guidelines exist on how to create social innovative products for poor markets. Purpose and research question The purpose of this study is to contribute to a better understanding of social product innovation for poor markets. This is done through investigating key factors to consider for SMEs emanating from developed countries in order to create social innovative products for these markets. Methodology This paper is a qualitative research and takes an exploratory approach, and uses a cross- sectional, multiple case study methodology. This study has investigated four products emanating from Swedish micro-SMEs, sold primarily in Tanzania, Zambia and Kenya. The empirical data was collected through conducting 12 semi-structured interviews. Results and conclusion The result of this paper contributed to a deeper understanding of social product innovation in subsistence markets. Theoretical guidelines in form of a model has been developed which summarizes 19 key factors that SMEs emanating from developed countries need to consider in order to create social innovative products for subsistence markets. Out of these, three are deemed to be of particular importance, namely the need to understand the marketplace, to develop the product in a price-based costing framework, and to scale.
