Geographic distribution of suicide and railway suicide in Belgium, 2008–2013: a principal component analysis

This study investigated the geographic distribution of suicide and railway suicide in Belgium over 2008--2013 on local (i.e., district or arrondissement) level. There were differences in the regional distribution of suicide and railway suicides in Belgium over the study period. Principal component analysis identified three groups of correlations among population variables and socio-economic indicators, such as population density, unemployment, and age group distribution, on two components that helped explaining the variance of railway suicide at a local (arrondissement) level. This information is of particular importance to prevent suicides in high-risk areas on the Belgian railway network.     

Swedish Multinationals and Competition from High- and Low-Wage Locations

This study uses data on Swedish multinationals to estimate cross-elasticities of labor demand in different locations. With a vertical decomposition of the firm's activities, whether there is substitution or complementarity between employment in different parts of the firm will depend on whether wage changes lead to a relocation of activities or simply to changes in marginal costs and/or demand for inputs in other parts of the firms. It is found that there is some evidence of a substitutionary relationship between employment in the Swedish parts of the firms and employment in other high-income locations, but no evidence of substitution stemming from employment in low-income locations.     

Swedish mothers’ and fathers’ worries about climate change: a gendered story

Abstract

The present study considers whether parenthood has an impact on the worries that women and men have about climate change for the next generation and examines whether there are differences between the worries of mothers and fathers. The empirical material is based on a questionnaire-based survey that was administered in 2011 to a random selection of 3500 individuals in Sweden, with a response rate of 31%. The results indicate that parenthood, regardless of the parent’s gender, increases an individual’s worries about the impact of climate change on the next generation. Fathers are significantly more worried about climate change than men who are not parents; however, mothers do not worry significantly more than women who are not parents. In general, regardless of parenthood status, women worry about climate change more than men.     

Rationale of internationalization of China's national oil companies: seeking natural resources,strategic assets or sectoral specialization?

The bulk of the existing literature emphasized that China's companies sought strategic assets (technology, brands and access to markets) through internationalization in order to overcome latecomers' comparative disadvantage, while some studies suggested that these firms went after natural resources to address China's rising oil imports. The third argument (which we coin the ‘sectoral strength’ hypothesis) suggested that the upstream firms in extractive business would seek natural resources, whereas downstream ones would seek strategic assets. In this study, we examine the rationale of main overseas investment deals (‘going out’) of China's two largest national oil companies during 2002–2010 which were also China's top two non-financial firms with the largest outward investment stocks during 2004–2010. We conclude that these deals can be best explained by the ‘sectoral specialisation’ hypothesis supplemented with a consideration for strategic assets.     

Modeling the rebound effect in two manufacturing industries

The rebound effect refers to the phenomenon that energy savings from improvements in energy efficiency are lower than expected due to unintended second-order effects. Grasping specific mechanisms related to the rebound effect requires a good understanding of interactions between heterogonous agents on multiple markets. Otherwise, policies aimed at reducing energy use may render counter-expected and unforeseen consequences. In this paper, we propose a formal model, where technological change results from interactions on two markets: between consumers and producers in the market for final goods, and heterogeneous power plants in the electricity market. The analysis provides insights to the role of technological change, supply–demand coevolution, and status-driven consumption in explaining the rebound effect. The model is employed to compare effectiveness of economic policies aimed at reducing carbon emissions associated with production of consumer goods, namely: a tax on electricity and ‘nuclear obligations’ to produce ten percent of electricity from nuclear energy.     

Location Choice and Employment Decisions: A Comparison of German and Swedish Multinationals

Using data on German and Swedish multinational enterprises (MNEs), this paper analyzes determinants of location choice and the degree of substitutability of labor across locations. Countries with highly skilled labor strongly attract German but not necessarily Swedish MNEs. In MNEs from either country, affiliate employment tends to substitute for employment at the parent firm. At the margin, substitutability is the strongest with respect to affiliate employment in Western Europe. A one percent larger wage gap between Germany and locations in Central and Eastern Europe (CEE) is associated with 760 fewer jobs at German parents and 4,620 more jobs at affiliates in CEE. A one percent larger wage gap between Sweden and CEE is associated with 140 fewer jobs at Swedish parents and 260 more jobs at affiliates in CEE. JEL no. F21, F23, J21, J23     

Trade and Location with Horizontal and Vertical Multi-region Firms

We analyse the effect on agglomeration tendencies of allowing multi-region firms in a standard trade and location model, the core–periphery (CP) model developed by Kurgman (1991). The introduction of horizontal multi-region firms mitigates the agglomeration effects found in the CP model by reducing the range of trade costs for which the core–periphery equilibrium occurs. The introduction of vertical multi-region firms that separate the location of headquarters and plants has two counteracting effects. While headquarters exhibit a strong tendency to concentrate, plants tend to spread out. The equilibrium is always asymmetric in spite of the underlying symmetry of the model.     

The interplay of formal and informal institutions between local and regional authorities when creating well-functioning public transport systems

This paper analyzes how public transport planning is managed in institutional contexts where governance is spread across local and regional scales. The paper sheds light on two facets of the relationship between local and regional government: first, the decision-making process regarding where to provide public transport services and at what level, and second, integration of public transport with land use planning. An analytical matrix is used to cross-reference the roles of formal institutions (governance established in law) and informal institutions (governance not established in law) against local and regional responsibilities for public transport and land use. Analysis of the interplay between these three axes (formal/informal, local/regional, public transport/land use) reveals how informal institutions help regional and local authorities to negotiate the constraints of formal, statutory institutions and help to “oil the wheels” of delivering measures and policies that make public transport work as a well-functioning system. However, informal institutions clearly have their limits, in the paper exemplified by the remaining challenges to integrate regional public transport and local land use planning. An identified challenge is that, by their very nature, informal institutions are difficult to influence or modify, therefore relying on them to fill gaps in formal institutional responsibilities may be a risky strategy when unpopular decisions are made.
