Contradictions of the Climate-Friendly City: New Perspectives on Eco-Gentrification and Housing Justice

As local governments and corporations promote ‘climate friendliness’, and a low-carbon lifestyle becomes increasingly desirable, more middle- and upper-income urban residents are choosing to live near public transit, on bike- and pedestrian-friendly streets, and in higher-density mixed-use areas. This rejection of classical forms of suburbanization has, in part, increased property values in neighborhoods offering these amenities, displacing lower-income, often non-white, residents. Increased prevalence of creative and technology workers appears to accelerate this trend. We argue that a significant and understudied socio-environmental contradiction also occurs where the actual environmental outcomes of neighborhood transformation may not be what we expect. New research on greenhouse gas emissions shows that more affluent residents have much larger carbon footprints because of their consumption, even when reductions in transportation or building energy emissions are included. We describe an area in Seattle, Washington, the location of Amazon's headquarters, experiencing this contradiction and show a distinct convergence of city investments in low-carbon infrastructure, significant rises in housing prices and decreases in lower-income and non-white residents. We conclude with a discussion of a range of issues that require more attention by scholars interested in housing justice and/or urban sustainability.     

Altruism and egoism in investment decisions

We provide survey evidence that personal values have an impact on individual investment decisions, in particular preferences for socially responsible investing. Our findings show that there is a positive link between altruistic values and the relative importance of social responsibility. This effect is stronger when individuals believe that they can make a positive social or environmental impact with their investments, or when they feel morally obliged to invest responsibly. If altruistic individuals associate responsible investments with higher returns, it decreases their motivation to invest responsibly. Egoistic values are negatively associated with the decision to invest responsibly, unless individuals associate responsible investing with higher returns.     

Reviewing the Field of External Knowledge Search for Innovation: Theoretical Underpinnings and Future (Re-)search Directions

The field of external knowledge search for innovation has a long tradition and has inspired several schools of thought resulting in a rich and burgeoning body of research. However, the field suffers from two key limitations. First, the pluralism of research across multiple disciplines impedes our attention to the field as a whole, including its intellectual structure and core ideas. Second, recent developments in the business environment and key new ideas in the field complement taken-for-granted approaches and provide new opportunities for knowledge search. Based on a systematic co-citation analysis, we provide a reflective review of the literature and make several contributions. We integrate existing research across disciplines and offer a synthesis of a fragmented research landscape to present a global view of the field. Moreover, we propose a novel external search concept and introduce the idea of “decoupled search.” Leveraging our synthesis and conceptualization further, we recommend future research directions for the entire field of external knowledge search for innovation.     

Aggregative games and oligopoly theory: short-run and long-run analysis

We compile an IO toolkit for aggregative games with positive and normative comparative statics results for asymmetric oligopoly in the short and long run. We characterize the class of aggregative Bertrand and Cournot oligopoly games, and the subset for which the aggregate is a summary statistic for consumer welfare. We close the model with a monopolistically competitive fringe for long-run analysis. Remarkably, we show strong neutrality properties in the long run across a wide range of market structures. The results elucidate aggregative games as a unifying principle in the literature on merger analysis, privatization, Stackelberg leadership, and cost shocks.     

Community-Based Tradable Permits for Localized Pollution

This paper considers the assignment of tradable permits—representing property rights of an environmental good—to community members who are harmed by pollution generated by firms. These community members can in turn sell permits to polluters according to their personal preferences. For a special case with a sole household, market transactions between the household and polluters achieve an efficient pollution level. However, for a group of households, the decentralized market solution fails to yield social efficiency because of competitive consumption of the environmental goods. We design a revenue-sharing mechanism akin to unitization, under which market transactions also achieve efficient resource allocation. Importantly, in some cases, efficiency can be achieved even when regulators are ignorant of the private valuation of the environmental good.     

The Economic Impact of Brexit: Evidence from Modelling Free Trade Agreements

This paper assesses the economic implications of the United Kingdom (UK) leaving the European Union (EU). The basic data on trade in goods and services and investment between the two parties suggest that the cost of “Brexit” could be substantial. Trade between the UK and the EU-27 is large and of a similar order of magnitude as transatlantic trade (between the EU and the U.S.). The precise nature of the (hopefully free) trade agreement UK-EU-27 is still being negotiated. All available studies concur that a significant disruption of trade links will impose economic costs on both sides. However, the EU-27 would bear only a disproportionally small share of the total cost, not just because it is about five times larger than the UK in economic terms, but also for fundamental reasons such as greater market power of its enterprises. Other studies on different free trade arrangements confirm the general proposition that the smaller party has more to gain from eliminating trade barriers (and more to lose from imposing them). This implies that the EU will have a stronger negotiating position.     

Reanalyzing Zero Returns to Education in Germany

Pischke and von Wachter (Review of Economics and Statistics 2008; 90 (3): 592–598) find zero earnings returns to compulsory schooling in the basic school track in Germany. We reanalyze their study using a different dataset. In an extension, we use additional instruments which allow estimation of heterogeneous effects for different groups of compliers. We can confirm the previous result and also find zero returns for other compliers in higher track schools. Moreover, we do not find a causal effect of schooling on cognitive skills. This is in line with a potential reason Pischke & von Wachter (2008) give for their result, namely that basic skills are learned earlier in Germany and additional years of schooling are no longer effective.
