Article
We study the causal impact of the negative shock on short-term rentals caused by covid-19 in the tourist-intensive city centre of Lisbon. Our difference-in-differences strategy uses a parish-level treatment relying on the pre-pandemic intensity of short-term rentals, using data between Q3 2018 and Q3 2020. The results suggest that landlords relocat...
Article
We use novel and comprehensive monthly data on electronic payments, by municipality and sector, together with cash withdrawals, to study the impact of Covid-19 in Portugal. Our difference-in-differences event study identifies a causal decrease of 17 and 40 percentage points on the year-on-year growth rate of overall purchases in March and April 202...

This paper analyzes the consequences of local fiscal autonomy with respect to political selection. We propose a model of political careers wherein the decisions to become candidates and to seek reelection are both endogenous. Private-sector aptitude and political ability are private information; the latter is revealed to the incumbent during her fi...

This paper uses novel and comprehensive data on electronic payments from SIBS, the main provider of point of sale terminals and on-line payments in Portugal, to study the impact of the Great Lockdown on purchases. The data aggregates all individual transactions into monthly observations, by municipality and sector, between 2018 and 2020. We employ...

Young voters’ political behaviour differs from the rest of the electorate in that they exhibit lower turnout and express different preferences. This article examines the impact of information provision about central government on young voters’ perception of government performance and their voting behaviour. We randomly exposed a sample of universit...
Article
L’abstention est un sujet de débat omniprésent dans la plupart des démocraties et ce pour deux raisons. Une de ces raisons est son importance croissante. Dans de nombreux pays démocratiques, un pourcentage croissant de la population décide de ne pas voter, suscitant de nombreux débats scientifiques, politiques et médiatiques. Même en Belgique, où l...

Article
We study the impact of transfer pricing rules on sales prices, firms’ organizational structure, and consumers’ utility within a two-country monopolistic competition model featuring source-based profit taxes that differ across countries. Firms can either become multinationals, i.e., they serve the foreign market through a fully controlled affiliate;...

Apesar de muitos sistemas de saúde terem optado recentemente pela descentralização, fica por esclarecer se os governos locais têm um melhor desempenho do que os centrais. Este artigo sumariza os principais resultados da teoria económica sobre o impacto da descentralização e a sua validade empírica. A decisão de descentralizar resulta duma arbitrage...

The explosion of globalization has increased firms incentives to exploit international tax differentials to their benefit. In this paper we consider a simple world with two countries with different market sizes and two multinationals with a division in each country. Both countries use a source-based profit tax on multinationals, who compete a la Co...
Article
Over the recent years, decentralization has been adopted in many health systems. The question however remains of whether local actors do better than the central government. We summarize the main insights from economic theory on the impact of decentralization and its empirical validation. Theory suggests that the decision to decentralize results fro...
Article
We study a firm which serves two unequally-sized jurisdictions and must choose where to locate its first production plant, and whether to open a second plant to serve the other market through local sales rather than exports. An exporter pays taxes only to the region where it locates its single production plant. A double-plant multi-regional firm pa...
Article
In this paper, we revisit the classical trade-off between centralized and decentralized provision of local public goods, in a setting where interregional spillovers depend on the level of a national public good. We compare the standard benevolent planner approach with a political economy in which decisions, in a centralized system, are undertaken b...
Article
We present a spatial model of a city with two unequally productive jurisdictions. City residents bear a commuting cost to work in either of the two jurisdictions. Each jurisdiction must finance a public budget with a wage and a head tax. We compare the first best optimum to tax decentralization. From the total welfare viewpoint, tax competition is...

Article
The paper considers a model of federation with two heterogeneous regions that try to attract the capital by competing in capital income taxes and public investment that enhance the productivity of capital. Regions' choices determine allocation of capital across the regions and their revenues under a tax sharing scheme. This framework allows for the...
Article
International markets for tradable emission permits (TEP) co-exist with national energy taxation. A firm trading emission permits in the international market also pays energy taxes in its host country, thus creating an interaction between the international TEP-market and national energy taxes. In this paper we model that interaction in a framework...

Given the background of changing institutional competencies in the European Union, we analyze the choice of asylum law standards of national and European parliaments, the Council of the European Union and codecision between the Council and the European Parliament. In a two country model we nd that the European arrangements maximize neither the welf...

The autonomy of local governments in deciding their revenue level varies a lot worldwide. We analyze the consequences of this autonomy from the viewpoint of political accountability. We study a two-period game in which elections take place at the end of the first period, in a model where local officials may be public or self interested. We show tha...
Article
We present a fiscal competition model with two policy instruments: the level of corporate taxation and the tightness of control of profit shifting by multinational firms (MNF). We show that a country may optimally decide not to monitor the MNF for two reasons. Firstly, this country becomes an attractive location for MNF activity despite a high corp...
Article
Revenue sharing can be used to discourage low tax regions from competing for capital and firms with high tax regions. However, with heterogeneous regions, revenue sharing involves net transfers across regions and creates a Òmoral-hazardÓ problem - that is, regions may want to invest less in market fostering public good when the benefits are shared...

Article
This paper addresses capital tax competition among an arbitrary number of countries. Countries are asymmetric not only in their population endowment but also in their capital endowment per inhabitant. National governments tax capital and labor in order to finance a fixed public budget. Asymmetric capital taxation arises at equilibrium leading to a...

Le 18 mai, les Belges sont appelés à voter. Ils en ont l’obligation, contrairement à la plupart de leurs homologues européens, qui sont nombreux à s’abstenir. L’abstention est-elle un danger pour la démocratie ? Le vote obligatoire apporte-t-il une solution ? Quelle est la contribution des théories économiques dans ce débat ?

We model two heterogeneous districts of unequal size that may enjoy each other's local public good if a costly national infrastructure (the bridge) is provided. We compare a decentralized regime where local public goods are decided locally and the bridge centrally, with a centralized regime where all decisions are taken centrally, under both benevo...

In 1997, the OECD published guidelines to assess transfer prices, prescribing the application of the "arm's length principle" whereby transfer prices should equal the transaction prices with non-affiliated firms. While the two mostly used rules are the "Comparable Uncontrolled Price" and the "cost-plus" rules, arm's length transfer pricing has been...

Project
In this joint project with Susana Peralta and João Santos we use a novel data set of electronic purchases to study the impact of the Covid-19 pandemic on the Portuguese economy. Our first paper focuses on the very short run impact, on the two first months of the confinement (March and April) the second uses data until August to evaluate regional and sectorial heterogeneity. We are currently working on a paper where we zoom into the Tourism and Hospitality sectors.
Project
Heterogeneity shapes both tax policies and tax incidence. We study the impact of heterogeneity on tax competition, tax enforcement and tax incidence both in a theoretical and empirical perspective.
Project
It is often stated that local electoral outcomes reflect voters’ perception about central governments’ performance and quality. Using the Portuguese local elections in 2017 as setting, we randomly exposed participants to positive, neutral and negative information about the central government in office at that time. We use a sample of undergraduate and masters students of two business schools in Lisbon. Our goal is to assess how information affects turnout and voting decision of voters in local elections. Beyond the randomized implementation, we look at 17-years old respondents (who are not allowed to vote) as an instrument variable where the ex-ante propensity to have acquired information is lower. We aim to contribute to the methodological literature by combining instrument variables with randomization.
