Background: Few studies have systematically examined the efficiency of routine infant immunization services. Using a representative sample of infant immunization sites in Benin, Ghana, Honduras, Moldova, Uganda and Zambia (316 total), we estimated average efficiency levels and variation in...

This paper examines the opportunity of exchange rate regime flexibilization in Morocco under the policy of capital account liberalization. Basing on our findings in Ezzahid and Maouhoub (2014), we develop a new theoretical game model with four economic agents, namely: monetary authorities,...

Two important aspects of global environmental problems are that (1) the actions of past generations affect the opportunities of the present, and (2) both in the past and the present generations, collaboration across different countries is needed to provide global public goods. In this paper, we...

How does salient public information affect voters' behavior? In a majoritarian voting game with common preferences, rational voters could use public information as an information device (depending on accuracy) or as a coordination device (regardless of accuracy). A simple lab experiment...

In experiments of decision-making under risk, structural mixture models allow us to take a menu of theories about decision-making to the data, estimating the fraction of people who behave according to each model. While studies using mixture models typically focus only on how prevalent each of...

This paper focuses on an architecture-based theory of agglomeration. An agglomeration is composed of a number of segments such as physical infrastructure facilitation including airports and stations. "Economies of sequence" can be defined as the sequencing of the segments toward the efficient...

This paper studies the role of the exchange rate regime for trade of new products. It first provides VAR evidence that a rise in external productivity shifts trade away from new products and more so in fixed regimes. Then, it presents a model with firm dynamics in line with this evidence. We...

Operational risk management remains a major concern for financial institutions. Indeed, institutions are bound to manage their own funds to hedge this risk. In this paper, we propose an approach to allocate one's own funds based on a combination of historical data and expert opinion using the...

This work investigates optimization techniques for a multi-period vehicle allocation problem with uncertain transportation requests revealed sequentially over a rolling horizon. Policies derived from deterministic scenarios are compared: they are generated either by simple heuristics, or by more...

Financial volatility obeys two fascinating empirical regularities that apply to various assets, on various markets, and on various time scales: it is fat-tailed (more precisely power-law distributed) and it tends to be clustered in time. Many interesting models have been proposed to account for...
