Quantitative Spatial Economics
The observed uneven distribution of economic activity across space is influenced by variation in exogenous geographical characteristics and endogenous interactions between agents in goods and factor markets. Until the past decade, the theoretical literature on economic geography had focused on stylized settings that could not easily be taken to the data. This article reviews more recent research that has developed quantitative models of economic geography. These models are rich enough to speak to first-order features of the data, such as many heterogeneous locations and gravity equation relationships for trade and commuting. At the same time, these models are sufficiently tractable to undertake realistic counterfactual exercises to study the effect of changes in amenities, productivity, and public policy interventions such as transport infrastructure investments. We provide an extensive taxonomy of the different building blocks of these quantitative spatial models and discuss their main properties and quantification.

Pandemics Depress the Economy, Public Health Interventions Do Not: Evidence from the 1918 Flu
We study the impact of non-pharmaceutical interventions (NPIs) on mortality and economic activity across U.S. cities during the 1918 Flu Pandemic. The combination of fast and stringent NPIs reduced peak mortality by 50 percent and cumulative excess mortality by 24 to 34 percent. However, while the pandemic itself was associated with short-run economic disruptions, we find that these disruptions were similar across cities with strict and lenient NPIs. NPIs also did not worsen medium-run economic outcomes. Our findings indicate that NPIs can reduce disease transmission without further depressing economic activity, a finding also reflected in discussions in contemporary newspapers.

African women : a political economy
\"This anthology gives a historically aware overview of the political and economic issues facing African women since Independence. It incorporates gender and transnational theory in its theoretical discussion of African women from the perspective of political economy. The three main themes are African feminism, women and work, and women and politics. The issue of women's control over labor is central, as is a comparative perspective of women's political movements. Written by Africans and Africanists, this significant and much-needed work is an examination of these themes and a critical evaluation of materialist thought on the political and economic aspects of African women's studies\"--Provided by publisher.

On the notion of regional economic resilience
Over the past few years a new buzzword has entered academic, political and public discourse: the notion of resilience, a term invoked to describe how an entity or system responds to shocks and disturbances. Although the concept has been used for some time in ecology and psychology, it is now invoked in diverse contexts, both as a perceived (and typically positive) attribute of an object, entity or system and, more normatively, as a desired feature that should somehow be promoted or fostered. As part of this development, the notion of resilience is rapidly becoming part of the conceptual and analytical lexicon of regional and local economic studies: there is increasing interest in the resilience of regional, local and urban economies. Further, resilience is rapidly emerging as an idea ‘whose time has come’ in policy debates: a new imperative of ‘constructing’ or ‘building’ regional and urban economic resilience is gaining currency. However, this rush to use the idea of regional and local economic resilience in policy circles has arguably run somewhat ahead of our understanding of the concept. There is still considerable ambiguity about what, precisely, is meant by the notion of regional economic resilience, about how it should be conceptualized and measured, what its determinants are, and how it links to patterns of long-run regional growth. The aim of this article is to address these and related questions on the meaning and explanation of regional economic resilience and thereby to outline the directions of a research agenda.

THE ECONOMICS OF DENSITY: EVIDENCE FROM THE BERLIN WALL
This paper develops a quantitative model of internal city structure that features agglomeration and dispersion forces and an arbitrary number of heterogeneous city blocks. The model remains tractable and amenable to empirical analysis because of stochastic shocks to commuting decisions, which yield a gravity equation for commuting flows. To structurally estimate agglomeration and dispersion forces, we use data on thousands of city blocks in Berlin for 1936, 1986, and 2006 and exogenous variation from the city's division and reunification. We estimate substantial and highly localized production and residential externalities. We show that the model with the estimated agglomeration parameters can account both qualitatively and quantitatively for the observed changes in city structure. We show how our quantitative framework can be used to undertake counterfactuals for changes in the organization of economic activity within cities in response, for example, to changes in the transport network.

ECONOMIC ACTIVITY AND THE SPREAD OF VIRAL DISEASES
Viruses are a major threat to human health, and—given that they spread through social interactions—represent a costly externality. This article addresses three main questions: (i) what are the unintended consequences of economic activity on the spread of infections; (ii) how efficient are measures that limit interpersonal contacts; (iii) how do we allocate our scarce resources to limit the spread of infections? To answer these questions, we use novel high frequency data from France on the incidence of a number of viral diseases across space, for different age groups, over a quarter of a century. We use quasi-experimental variation to evaluate the importance of policies reducing interpersonal contacts such as school closures or the closure of public transportation networks. While these policies significantly reduce disease prevalence, we find that they are not cost-effective. We find that expansions of transportation networks have significant health costs in increasing the spread of viruses, and that propagation rates are pro-cyclically sensitive to economic conditions and increase with inter-regional trade.
