New fast estimation methods stemming from control theory lead to a fresh look at time series, which bears some resemblance to "technical analysis". The results are applied to a typical object of financial engineering, namely the forecast of foreign exchange rates, via a "model-free" setting,...

In the present paper, we consider a two-country, two-good, two-factor general equilibrium model with CIES non-linear preferences, asymmetric technologies across countries and decreasing returns to scale. It is shown that aggregate instability and endogenous fluctuations may occur due to...

This paper studies the impacts and determinants of trade policy. I use data on applied tariff protection of world countries over 2001-2007 to estimate sector-level trade elasticities. I then calibrate a structural gravity model of world trade. I compute the impacts of trade agreements which were...

Import price elasticity tends to be under-estimated due to the omission of quality effects. This dissertation aims to fill this gap by analyzing 1) how quality effects affect the estimation of import price elasticity, 2) the impact of quality innovation in the various goods sectors of an economy...

The empirical U-shaped pattern between product diversification and economic development has been widely examined, but here we analyze the determinants of diversification. We find that a high level of rent-seeking activities has a large impact on the diversification of nations : in countries...
