This paper derives a micro-founded gravity equation in general equilibrium based on a translog demand system that allows for endogenous markups and rich substitution patterns across goods. In contrast to standard CES-based gravity equations, trade is more sensitive to trade costs if the...

How do trade costs affect international trade? This paper offers a new approach. We rely on a flexible gravity equation that predicts variable trade cost elasticities, both across and within country pairs. We apply this framework to the effect of currency unions on international trade. While we...

We study the effects of two dimensions of teacher quality, subject knowledge and didactic skills, on student learning in francophone Sub-Saharan Africa. We use data from an international large-scale assessment in 14 countries that include individual-level information on student achievement and...

While examining the macroeconomic effects of increased government control of the informal sector, this paper develops a two-sector general equilibrium model featuring matching frictions and worker-firm wage bargaining. Workers search for jobs in both the formal and the informal sector. We...

Fiscal consolidation literature often neglects that there are economies with a sizable underground sector and that most of time it is accounted in GDP statistics. This produces non negligible effects on fiscal multipliers. This paper explores a fiscal consolidation plan calling for a downsizing...

Vast literature is available covering main Informal Economy (IE) causes and consequences for Latin America and Caribbean (LAC), but its size estimation has been mainly limited to worldwide models applied to the region. This paper proposes a MIMIC Base Model using a data set composed by 41...
