Hamburg's Spaces of Danger: Race,Violence and Memory in a Contemporary Global City

Germany today is experiencing the strongest upsurge of right‐wing populism since the second world war, most notably with the rise of Pegida and Alternative für Deutschland. Yet wealthy global cities like Hamburg continue to present themselves as the gatekeepers of liberal progress and cosmopolitan openness. This article argues that Hamburg's urban boosterism relies on, while simultaneously obscuring, the same structures of racial violence that embolden reactionary movements. Drawing on the work of Walter Benjamin and Allan Pred, we present an archaeology of Hamburg's landscape, uncovering some of its ‘spaces of danger’—sites layered with histories of violence, many of which lie buried and forgotten. We find that these spaces, when they become visible, threaten to undermine Hamburg's cosmopolitan narrative. They must, as a result, be continually erased or downplayed in order to secure the city as an attractive site for capital investment. To illustrate this argument, we give three historical examples: Hamburg's role in the Hanseatic League during the medieval and early modern period; the city under the Nazi regime; and the recent treatment of Black African refugees. The article's main contribution is to better situate issues of historical landscape, collective memory and racialized violence within the political economy of today's global city.

Becoming a historical thinker might be the first step for developing a consciousness of reasoned conciliation

The goal of this presentation is to examine the hypothesis that the ethno-political conflict in Israel can be utilized in history education to foster learning of historical thinking and to construct a tolerant space within the education system that will enable the structuring of in-principle criteria for coexistence prior to the ending of the conflict. I assumed that inculcation of historical knowledge in the education system in Israel by means of an attentive and reflexive cultural dialogue, which sensitively and skillfully confronts contradictory historical narratives as an everyday learning reality in class, will help structure a conciliatory consciousness of the kind we seek.

Memory recall errors in retrospective surveys: A reverse record check study

This paper reports on a study to compare self-reports during an interview with staff who attended a University health centre in Turkey, with the records of visits to the same health centre over the previous 12 months. Design of the study reflects the effects of importance of the event, duration since the event, frequency of the occurrence of the event, measurement scale of the event, and bounded and unbounded recalling. In order to assess the extent of recall error, responses to retrospective questions on health centre visits are compared with administrative records. Statistical models are proposed for short and long term human memory recall error effects on responses.

The price normalization problem in imperfect competition and the objective of the firm

Summary. General equilibrium models of oligopolistic competition give rise to relative prices only without determining the price level. It is well known that the choice of a numéraire or, more generally, of a normalization rule converting relative prices into absolute prices entails drastic consequences for the resulting set of Nash equilibria when firms are assumed to maximize profits. This is due to the fact that changing the price normalization amounts to altering the objective functions of the firms. Clearly, the objective of a firm must not be based on price normalization rules void of any economic content. In this paper we propose a definition of the objective of a firm, called maximization of shareholders' real wealth, which takes shareholders' demand explicitly into account. This objective depends on relative prices only. Real wealth maxima are shown to exist under certain conditions. Moreover, we consider an oligopolistic market and prove the existence of a Nash equilibrium in which each firm maximizes the real wealth of its shareholders.

Regulatory tune-ups

Regulators cannot continuously and perfectly monitor firms. The alternative considered here supposes the regulator sets prices at discrete, unforeseen, times. I show that when marginal cost follows a stochastic diffusion process, but the regulator only irregularly adjusts the regulated price, the optimal price may be less than or greater than the expected level of marginal costs. The regulated price should be higher the steeper the demand curve, the lower the discount rate, and the greater the variance of costs. The social benefit of changing the price following a change in marginal cost is usually greater if at the time price was set marginal cost was low.     

Market Structure and Fiscal Policy Effectiveness

In a monopolistic competition macromodel with endogenous market structure, the fiscal multiplier is shown to consist of two components. The first depicts the response of output to a fiscal expansion through the conventional channels that disregard the role of market imperfections. The second component captures the effects of firms' market power as well as the policy-induced change in market structure. The latter effect—which has not been taken into account in existing studies—is shown to be quite significant in raising the fiscal multiplier (even above unity) and in improving consumers' welfare when the labour market is competitive.
