We develop a theoretical framework that considers the role played by moral hazard and the diversity of networks and cultures in the choice of hiring channel. In favoritism contexts social networks, and particularly strong ties, are adopted as hiring channels for unskilled jobs and result in wage...

We provide a first attempt to include o?-balance sheet, implicit insurance to SIFIs into a consistent assessment of fiscal sustainability, for 27 countries of the European Union. We first calculate tax gaps a la Blanchard (1990) and Blanchard et al. (1990). We then introduce two alternative...

This paper aims at explaining two stylized facts of the Lost Decade in Japan: rising wage inequalities and increasing firm-level productivity differentials. We build a model where firms can choose between efficiency wages with endogenous effort and competitive wages, and show that it can...

What influences banks’ borrowing costs in the unsecured money market? The objective of this paper is to test whether measures of centrality, quantifying network effects due to interactions among banks in the market, can help explain heterogeneous patterns in the interest rates paid to borrow...

Governments and central banks need to have an accurate and timely assessment of Gross Domestic Product's (GDP) growth rate for the current quarter, as this is essential for providing a reliable and early analysis of the current economic situation. This paper presents a series of models conceived...

In this paper, we provide determinacy conditions, i.e. conditions ensuring the existence and uniqueness of a bounded solution, in a purely forward-looking linear Markov switching rational expectations model. We thus settle the debate between Davig and Leeper (2007) and Farmer et al. (2010). The...

In this paper, I study how the CEO's election can be biased if some directors in the board belong to the same network. I use a static Bayesian game. Directors want to elect the best candidate but they also want to vote for the winner. In that context, results show that, when no candidate is part...

We assess the role played by fiscal policy in explaining the dynamics of asset markets. Using a panel of ten industrialized countries, we show that a positive fiscal shock has a negative impact in both stock and housing prices. However, while stock prices immediately adjust to the shock and the...

Advertising and innovation are two engines for firms to escape competition through a better attraction power toward consumers or quality advantage. We propose a model that encompasses both the static and dynamic interactions between R&D, advertising and competitive environment. This model...

This paper shows that the impact of changes in budgetary variables on major macroeconomic variables varies in sign and magnitude in times of crisis and non-crisis in France. We find that these nonlinearities are both frequent (as they exist on all behaviors analyzed: real GDP, private...
