Concrete U(dys)topia in Bethlehem: a city of two tales

The aim of this article is to deconstruct the utopian character of Israel by analysing the case of Rachel's Tomb in Bethlehem. In this illustration of how cultural heritage became dominated by Israel's utopia, this article proposes to create an inspirational alternative. Therefore, two tales of Bethlehem will be juxtaposed. Participatory observation and interviews were conducted in order to examine the context of Rachel's Tomb as well as the family of Claire Anastas. On this platform, different groups of people were invited to discuss complex political issues within the context of alternative tourism. By using Arendt's concept of the ‘agora’ and Habermas' theoretical framework, the lifeworld situation of the Palestinians has been addressed seriously. This creates the necessary condition in order to create hope in a highly politically unstable situation, such as the occupation and colonisation of the Palestinian territories. A critical value-laden perspective supports a stronger concept of communicative action in controversial areas. This concept functions as a structured approach to find an escape from the utopian supremacy of the Israeli ideology. It is an inclusive attempt to create room for a plural dialogue between all the lifeworlds of this region, Palestinians and Israelis.     

Firm heterogeneity and worker turnover

Previous empirical analyses of job mobility focus on worker rather than firm characteristics. This paper exploits a unique data set on enterprise employment. We describe sectoral differences in turnover rates and in the persistence of turnover. We also present evidence of persistent turnover differences at the level of the individual firms—a result that is expected if firms have managers with differing ability to screen workers. When we consider the consequences to the firm of such turnover, we discover that high turnover firms are less likely to survive.     

Nash as an Organizing Principle in the Voluntary Provision of Public Goods: Experimental Evidence

Experiments are reported that add to the growing literature on the voluntary provision of public goods. Information conditions are manipulated to address whether early findings of above-equilibrium contributions to a public good are a result of complete information regarding the symmetry of the game. No significant information effect was found. Further, by examining designs with an interior Nash equilibrium, this research suggests that the nonzero contributions observed in the previous dominant strategy environments, where the prediction was a zero level of provision of the public good, were not simply transitional errors as the system converged to a boundary equilibrium.

Market share and price rigidity

Survey evidence shows that the main reason why firms keep prices stable is that they are concerned about losing customers or market share. We construct a general equilibrium model in which firms care about the size of their customer base. Firms and customers form long-term relationships because consumers incur costs to switch sellers. In an environment with sectoral productivity shocks, we show that cost pass-through is a non-monotonic function of the size of switching costs. Specifically, prices tend to become more stable as the fraction of repeat customers increases and the elasticity of the customer base falls.     

Index composition changes and the cost of incumbency

This paper provides evidence of information effects and portfolio rebalancing effects that occur when stocks are added to or excluded from the S&P 500 index and finds that incumbents in the index realize negative excess returns when S&P revises the composition of the index. We also find that for incumbents that are in the same industry as the added firm, the price-pressure effects are mitigated by positive industry-level information and momentum effects. For index exclusions, the magnitude of the loss sustained by incumbents from the same industry as the excluded firm is larger than that realized by the non-industry incumbents, as the negative information and momentum effects reinforce the price-pressure effects. Our results suggest that changes in the composition of the index are not information-free events; however, the portfolio rebalancing effects dominate the industry information effects.

Information Gathering and Marketing

Consumers have only partial knowledge before making a purchase decision, but can acquire more‐detailed information. Marketing makes it easier or harder for these consumers to do so. When consumers are ex ante heterogeneous, the firm might choose an intermediate marketing strategy for two quite different reasons. First, as a nonprice means of discrimination—it can make information only partially available, in a way that induces some, but not all, consumers to acquire the information. Second, when the firm cannot commit to a given investment in ensuring quality, the marketing and pricing strategy can act as a commitment device.
