We develop an epidemionomic model that jointly analyzes the health and economic responses to the COVID-19 crisis and to the related containment and public health policy measures implemented in Luxembourg. The model has been used to produce nowcasts and forecasts at various stages of the crisis. We focus here on two key moments in time, namely the deconfinement period following the first lockdown, and the onset of the second wave. In May 2020, we predicted a high risk of a second wave that was mainly explained by the resumption of social life, low participation in large-scale testing, and reduction in teleworking practices. Simulations conducted 5 months later reveal that managing the second wave with moderately coercive measures has been epidemiologically and economically effective. Assuming a massive third (or fourth) wave will not materialize in 2021, the real GDP loss due to the second wave will be smaller than 0.4 percentage points in 2020 and 2021. [less ▲]

How would cities change if working from home (WFH) persisted in the post-pandemic era? This paper investigates the impact of WFH in the internal structure of monocentric cities, where production is characterized by management and employee spillovers. We find that business land rents decrease, while residential land rents fall close to the business center and increase in the suburbs. WFH raises urban productivity and average wages only in large cities. The paper also studies the optimal fraction of WFH from a residents and welfare point of view. Our results suggest that workers-residents have incentives to adopt an inefficiently high WFH scheme. We finally discuss the implementation of remote work in the short run. We show that WFH implies higher benefits for long distance commuters and lower benefits or even losses for firms and short distance commuters. [less ▲]

This paper investigates a trade model with many countries, many goods produced in multiple quality versions and non-homothetic preferences. It studies the impact of productivity, population changes and trade costs on the quality composition of exports. The analysis embeds within the same model a series of empirical results about high-income countries specialization and trade in higher quality goods. Product di¤erentiation matters at explaining the volumes of trade quality. High-quality goods exhibiting a high degree of di¤erentiation are traded only by high-income countries. [less ▲]

This paper studies the e¤ects of income heterogeneity on monopolistically competitive product markets and welfare in the context of non-homothetic preferences. When richer individuals expenditures are less sensitive to price change compared to poorer ones , a mean-preserving contraction of income distribution entices rms to charge higher prices, new rms enter and broaden product diversity. General equilibrium e¤ects have a negative impact on poorer individuals and, in speci c circumstances, on whole population. In open economies, lower income inequality in a country creates a price divergence between countries and decreases trade volumes and values. Those general equilibrium e¤ects are quantitatively non negligible. [less ▲]

This article studies the provision of urban green areas in cities where residents have preferences for the size of and access to those areas. At the optimum, the number of urban green spaces is a nonmonotone function of distance to the city center, while the sizes and distances to other urban green areas increase as one moves to the urban fringe. This article empirically investigates those properties for the 300 largest European cities by using the Global Monitoring Environment Services Urban Atlas database (European Environmental Agency). The empirical analysis confirms the nonmonotone relationship between the number of urban green spaces and the distance to the city center. The distance between two parks also increases as one moves toward the urban fringe. [less ▲]

This paper studies the size and location of small urban green areas across city spaces. Small urban green areas offer amenities that affect residential choices, land consumption and land rent. This paper discusses the land use and locations of those areas and the resulting residential space allocation. It is shown that the land share dedicated to small urban green areas results from the trade-off between land value and population density and is a single peaked function of the distance to the city center. This result is confirmed by the empirical study of urban structures in the 305 largest EU cities using GIS data. This spatial pattern is shown to be robust to many measures of urban land uses.

This paper investigates the impact of local traffic pollution on the formation of residential and business districts. While firms benefit from local production externalities, households commute to their workplaces with private vehicles and exert a local pollution externality on the residents living along the urban transport networks. The spatial location of firms and residents endogenously results from the trade-off between the production and pollution externalities and the commuting costs. The analysis shows that in monocentric cities the benefits associated with a fall in per-vehicle pollution are absorbed by rents paid to absentee landlords. When a city includes business and residential districts as well as a district mixing both agents, a lower per-vehicle pollution enlarges the residential districts and shifts the business districts closer to the geographical center of the city. The paper finally studies the optimal city structure. The first-best policies that fully internalize the externalities still foster business agglomeration. [less ▲]

In this paper we investigate the effect of local interaction in a simple urban economics model. Agents interact with others if and only if their interaction benefit outweighs their travel cost and therefore meet others only within finite geographic windows. We show that two or more cites may co-exist at the equilibrium provided that they are sufficiently distant. For any interaction surplus function, there exists a unique spatial equilibrium on not too large city supports. The population density within a city is determined by a second order advance-delay differential equation, whose solutions are fully characterized for linear interaction surplus functions. Numerical analyses show that more localized interactions yield flatter population density and land rents over larger extents of the city support. They do not give support to the idea that multiple subcenters can be caused by small and finite geographic windows of interaction. [less ▲]

We study a trade model with vertical product differentiation with many goods that are heterogeneous in cost and quality and produced in two quality versions. We discuss the composition of high- and low-quality goods in the workers’ consumption baskets in countries between comparable countries. We show that a larger country population fosters its specialization in high-quality production while a higher country productivity leads to specialization in high quality production for all countries. Smaller trade costs foster specialization in high quality exports. We then discuss the effect of population heterogeneity on the consumption baskets and country specialization. Most of those results agree with existing empirical findings. [less ▲]

New Economic Geography (NEG) provides micro-economic foundations for explaining the spatial concentration of economic activities across regions, cities, and urban areas. The origins of the NEG literature trace back to trade, location, and urban economics theories. In NEG, agglomeration and dispersion forces explain the existence of spatial agglomerations. A NEG model usually incorporates a combination of such forces. In particular, firm proximity to large markets and the importance of linkages along a supply chain are typical agglomeration forces. Equilibria properties derived from NEG models are very specific to NEG as they involve multiple equilibria and have a very high dependence on changes in parameters. This phenomenon has important implications for the emergence of nations, regions and cities. In particular, high transport costs imply the dispersion of economic activities, while low transport costs lead to their spatial concentration. The same forces that shape inequalities and disparities between regions also shape the internal structure of cities. Firms concentrate in urban centres to gain greater access to larger demand. The empirical literature has developed several approaches that shed light on spatial agglomeration and estimate the role and impact of transport costs on market access. A key empirical research question is whether observed patterns could be explained by location amenities or agglomeration forces as put forward by NEG. Quasi-experimental methodology is frequently used for such a purpose. NEG theory is supported by empirical evidence, demonstrating the role of market access. [less ▲]

As cities grow and spatially expand, agricultural land is converted into residential land. In many developing countries, especially in Sub-Saharan Africa, this process is accompanied by a change in land tenure, whereby plots held under traditional customary arrangements are sold to new urban residents, possibly with formal property rights. This paper studies joint land-use and land-tenure conversion in an urban economics model in which intermediaries purchase agricultural land from customary owners and attempt to transform it into residential plots with statutory property rights. The spatial equilibrium includes a mix of land uses and rights where statutory and non-statutory residential plots coexist with customary land that is mainly used for agriculture. Because customary ownership is subject to uncertainty (because of tenure insecurity), the conversion process includes a potential information asymmetry between customary owners and intermediaries. The analysis shows that a market failure may emerge whereby some customary owners prefer to continue farming their land rather than participate in the urban residential land market, which results in a city that is too small. Empirical analysis using Malian data validates the key features of the model captured by land price gradients, as well as the ranking and the variance of land prices, and is suggestive of the presence of information asymmetry.

Urban green areas cover more than 6% of urban land in Europe. This paper quan-tifies the impact of urban green areas on city structures for more than 300 Europeancities. It discusses the economic effects of the local amenity produced by green urbanareas using an urban economics model with various set of preferences. It estimatesthose models using data on detailed residential land uses, green urban areas and popu-lation density. It finally assesses the economic effects of reducing urban green areas incounterfactual exercises where cities are closed and open to migration and green urbanland is converted to residential plots or not. By this strategy, the economic assess-ment accounts for the general equilibrium effects through endogenous land prices andresidential space and location choices. It shows that the gross benefits of urban greenareas are substantial. A uniform removal of half of the urban green areas is equivalentto 6-9% reduction of household annual income. However, the conversion of those areasto residential plots brings a net gain of approximately 4% [less ▲]

In this paper, we develop a model of spatial segregation mediated by competitive land prices. Agents of two groups consume city land and benefit from social interactions. Because of cultural or ethnic differences, intragroup interactions are more frequent than intergroup ones. When group sizes differ, population groups sort into distinct neighborhoods. We characterize two‐ and three‐district urban structures. For high population ratios or strong intergroup interactions, only a three‐district city exists. In other cases, multiplicity of equilibria arises. Both groups generally rank these equilibria differently.

The purpose of this paper is twofold. We first investigate whether product market regulations affect commodity taxation in open-to-trade economies, and second, we study the strategic interaction in regulatory measures between trading partner countries. We present a two-country general equilibrium model in which destination-based commodity taxes finance public goods, and product market regulation affects both the number of firms in the market and product diversity. Based on data for 21 OECD countries over the 1990–2008 period, we provide empirical evidence suggesting that product market regulations are strategic complement policies and that domestic regulations have a negative impact on domestic commodity taxation.

This paper studies the time slot allocation of flight departures when travelers have a preference for departing on peak times and the number of available peak-time slots is constrained by airport capacities. We show that, compared to public airports, private airports may restrain their supply of peak slots strictly below their capacity levels when they serve airlines that compete to the same destinations. Such an inefficiency takes place in airports that have low per-passenger charges and are not too busy. It does not occur in the absence of competition in destination markets. [less ▲]

This paper discusses a trade model with many countries, many goods produced in multiple quality versions, and non-homothetic preferences. It embeds in the same model a series of results that have been empirically confirmed: high-income countries specialize in the production of high-quality goods and trade more of those. Richer countries purchase more high-quality varieties. They import more high-quality products from the most productive exporters. The paper then studies the impact of productivity and population changes on the quality composition of exports. It finally explains why countries import higher quality goods from more distant countries. [less ▲]
