51 p, 666.0 KB Fiscal consolidation with tax evasion and corruption / Pappa, Evi (European University Institute (Itàlia)) ; Sajedi, Rana (European University Institute (Itàlia)) ; Vella, Eugenia (European University Institute (Itàlia))
Using cross country data we show that tax evasion and corruption are highly important for determining the size of the . scal multiplier. We introduce these two features in a New Keynesian model with search and matching frictions, in order to revisit the e¤ects of tax and expenditure based consolidations. [...]

35 p, 428.9 KB Matching Markets under (In)complete Information / Ehlers, Lars (Université de Montréal) ; Massó, Jordi (Universitat Autònoma de Barcelona)
We introduce incomplete information to centralized many-to-one matching markets. This is important because in real life markets (i) any agent is uncertain about the other agents' true preferences and (ii) most entry-level matching is many-to-one (and not one-to-one). [...]

55 p, 354.5 KB La moderna teoria de l'elecció social : de la impossibilitat a la possibilitat / Massó, Jordi (Universitat Autònoma de Barcelona. Departament d'Economia i d'Història Econòmica)
Es presenten els dos teoremes d'impossibilitat més importants de la moderna teoria de l'elecció social: el teorema d'Arrow per a funcions de benestar social no dictatorials que satisfan el principi de Pareto i la propietat de la independència d'alternatives irrellevants, i el teorema de Gibbard-Satterthwaite per a funcions d'elecció social no trivials i no manipulables. [...]
We present the two most important impossibility theorems of the modern social choice theory: Arrow’s theorem for social welfare functions satisfying the Pareto principle and the independence of irrelevant alternatives property, and Gibbard-Satterthwaite’s theorem for non-trivial and strategy-proof social choice functions.

28 p, 694.1 KB The outcome of competitive equilibrium rules in buyer-seller markets when the agents play strategically / Pérez-Castrillo, David (Universitat Autònoma de Barcelona. Departament d'Economia i d'Història Econòmica) ; Sotomayor, Marilda A. Oliveira (Universidade de São Paulo)
We analyze the two-stage games induced by competitive equilibrium rules for the buyer–seller market of Shapley and Shubik (Int J Game Theory 1:111–130, 1972). In these procedures, first sellers and then buyers report their valuation and the outcome is determined by a competitive equilibrium outcome for the market reported by the agents. [...]

30 p, 322.3 KB On the manipulability of competitive equilibrium rules in many-to-many buyer-seller markets / Pérez-Castrillo, David (Universitat Autònoma de Barcelona. Departament d'Economia i d'Història Econòmica) ; Sotomayor, Marilda A. Oliveira (Universidade de São Paulo)
We analyze the manipulability of competitive equilibrium allocation rules for the simplest many-to-many extension of Shapley and Shubik’s (Int J Game Theory 1:111–130, 1972) assignment game. First, we show that if an agent has a quota of one, then she does not have an incentive to manipulate any competitive equilibrium rule that gives her her most preferred competitive equilibrium payoff when she reports truthfully.

50 p, 1.3 MB Should I stay or should I go? Austerity, unemployment and migration / Bandeira, Guilherme ; Caballé, Jordi ; Vella, Eugenia
High unemployment and fiscal austerity during the recent crisis have led to significant migration outflows from the periphery of the euro area. This paper introduces endogenous migration both for the unemployed and employed members of the household in a small open economy DSGE model with search and matching frictions. [...]

41 p, 664.8 KB The government wage bill and private activity / Bermperoglou, Dimitrios ; Pappa, Evi ; Vella, Eugenia
We estimate the effects of public wage expenditures on output and the labor market in U. S. data by identifying shocks to public employment and public wages using sign restrictions. Public wage shocks do not induce significant effects on output, but disaggregating by government level reveals that their effects can be contractionary at the federal level and expansionary at the state and local level.

New Keynesian models with unemployment and incomplete markets are rapidly becoming a new workhorse model in macroeconomics. Such models typically require heavy computational methods which may obscure intuition and overlook equilibria. [...]

(Universitat Autònoma de Barcelona. Departament de Filologia Anglesa i de Germanística) ; Universitat Autònoma de Barcelona. Facultat de Filosofia i Lletres
The purpose of this study is to examine the differences that arise across matching and mixed proficiency dyads in terms of meta-linguistic discourse (LREs). Most specifically, the present study bases its analysis on native speakers of Catalan in their process of learning English as a foreign language (FLA). [...]
Aquest estudi pretén analitzar les diferències que sorgeixen entre parelles del mateix nivell i parelles en què s’hi combinen dos nivells diferents. En concret, la recerca es focalitza en les diferències que s’originen entre aquests dos grups en termes de discurs metalingüístic. [...]

Para facilitar a los bomberos la extinción de incendios se quiere hacer uso de técnicas de visión por computador con el objetivo de detectar elementos sobre un terreno y geolocalizarlos. Este TFG se basa en una manera de llevar a cabo la geolocalización: Poner en correspondencia las imágenes tomadas por un vehículo aéreo no tripulado (UAV) con un ortomapa del cual ya se conocen las coordenadas de cada pixel.

Departament d'Economia i d'Història Econòmica) ; Centre de Referència en Economia Analítica
We study Bayesian Nash equilibria of stable mechanisms in centralized matching markets under incomplete information. We show that truth-telling is a Bayesian Nash equilibrium of the revelation game induced by a common belief and a stable mechanism if and only if all the profiles in the support of the common belief have singleton cores.
