CY - Potsdam ER - TY - RPRT A1 - Sanner, Helge T1 - Bargaining structure and regional unemployment insurance N2 - This study examines how the size of trade unions relative to the la- bor force impacts on the desirability of different organizational forms of self-financing unemployment insurance (UI) for workers, firms, and with reference to an efficiency criterion. For this purpose, we respectively nu- merically compare the outcome of a model with a uniform payroll tax to a model where workers pay taxes according to their systematic risk of unemployment. Our results highlight the importance of the bargaining structure for the assessment of a particular UI scheme. Most importantly, it depends on the size of the unions whether efficiency favors a uniform or a differentiated UI scheme.

Dieser Beitrag verwendet ein raumwirtschaftliches Standardmodell, um zu zeigen, dass dies nicht immer so sein muss. Der Grund ist, dass durch den Marktzutritt gerade die Konsumenten, deren Preiselastizität am größten ist, von dem Unternehmen bei der Preisbildung nicht berücksichtigt werden.

CY - Potsdam ER - TY - RPRT A1 - Sanner, Helge T1 - Economy vs. history BT - What does actually determine the distribution of firms' locations in cities? N2 - The aim of this study is to examine in which cases economic forces or historical singularities prevail in the determination of the long-run distribution of firms. We develop a relatively general model of heterogenous firms' location choice in discrete space. The main force towards an agglomerated structure is the reduction of transaction costs for consumers if firms are located closely, whilst competition and transport costs work towards a more disperse structure. We then assess the importance of the initial conditions by simulating and comparing the resulting distribution of firms for identical economic parameters but varying initial settings. If the equilibrium distributions of firms are similar we conclude that economic forces have prevailed, while differences in the resulting distributions indicate that 'history' is more important. The (dis)similarity of distributions of firms is calculated by means of a measure, which exhibits a number of desirable features.

N2 - This study examines in which cases economic forces or historical singularities prevail in the determination of the spatial distribution of retail shops. We develop a model of location choice in discrete space. The main force towards an agglomerated structure is the reduction of transaction costs for consumers if retailers are located closely, whilst competition and transport costs work towards a disperse structure. We assess the importance of the initial conditions by simulating the resulting distribution of shops for identical economic parameters but varying initial settings. If the equilibrium distributions are similar we conclude that economic forces have prevailed, while dissimilarity indicates that 'history' is more important. The (dis)similarity of distributions of shops is calculated by means of a metric measure.

The existence and the extent of UI are endogenously derived by maximising an objective function of the state. Three different types of regionalisation are considered which differ with respect to the area the UI objective function is related to, and with respect to the policy variable used to maximise it. It comes to light that workers are always in favour of central UI, while it depends on the type of regionalisation whether or not firms are better off with regional or with central UI. The same somewhat surprising result applies for efficiency.
