Since the early 2000s, biofuel production and trade have grown up at a very fast pace. As a result of ambitious programs in OECD countries, biofuel output has increased fourfold, and trade in ethanol expanded from US$ 1.7 billion in 2004 to US$ 5.5 billion in 2008. This trend is expected to continue: in the United States, the Energy Independence and Security Act passed in 2007 set the objective of 36 billion gallons of biofuel for road transportation by 2022. In the European Union, the Directive on Promotion of the Use of Energy from Renewable Sources, finally adopted in April 2009, confirmed the 10% bioenergy share in the EU road transportation by 2020. These policies have been decided based on several biofuels theoretical virtues: first, they alleviate the dependency on oil imports. Second, their production brings complementary revenues to farmers; and last but not least, biofuels have a lower environmental footprint than fossil fuels, since their use implies less greenhouse gas emissions. But the rent sharing of this consumption mandate is a sensitive issue. The United States and the European Union will unlikely produce all their needs domestically, especially since first generation fuels (ethanol from corn, wheat, sugar crops and biodiesel from rapeseed, soy and palm oil) appear to be by far the main source of supply for the next decade. Domestic production is politically attractive, but alternative production pathways can be more affordable and more environmentally friendly in other parts of the world. For example, the production cost for sugar cane ethanol is one third cheaper in Brazil than in the United States, and palm oil yield is five times the rapeseed one. Brazil has a great potential to meet a large share of developed economies’ needs for ethanol. In spite of some market access restrictions, 8% of the ethanol consumed in the US, and 25% of that consumed in the EU come from Latin America. Biodiesel trade is more liberalised, even though there may be occasional setbacks as in March 2008 when the European Commission imposed an anti-dumping tariff and countervailing duties on biodiesel originating from the US. Recently, net CO2 emission reductions have been questioned regarding some biofuel production processes (corn ethanol produced with coal-fired energy, for example) and differentiated reduction targets have been set in the US and the EU. The debates have become even more complex with collateral effects related to the change in the use of land. The need for an expansion in arable land is expected to highly increase greenhouse gas emissions related to deforestation and conversion of idle land to cropland. Consequently, both the US Environmental Protection Agency and the European Commission have decided that these effects should be considered, measured, and addressed in the legislation in order to assess the eligibility of ethanol to be produced. The CEPII, in a joint study with IFPRI, has made its own assessment of the indirect effects of biofuel production with a Computable General Equilibrium analysis using an extended version of the MIRAGE model. The study confirms that the impact of biofuel mandates on ethanol and biodiesel –besides the high cost of this policy– is harmful in the short run and that several decades of sustained biofuel production would be needed to repair the initial environmental damage of expanded cropping area. Additional studies, however, would be helpful to discern the exact effects of different crops grown in different regions. Research on these topics is still at an infant stage, especially when it comes to indirect effects through land use change, which are still poorly understood. However, taking into account more precisely environmental impacts related to a production pathway (with direct and indirect effects) and enacting a legislation defining eligible goods on the domestic market is certainly an interesting shift. It will require strong input from science but, as long as it can resist protectionist temptations, it could help reshape, in a more sustainable way, the trade structure of numerous agricultural goods.

The real impact of immigration on the host economy is still hotly debated. While there is a strong literature tradition to focus on the immigrants' impact on employment and wages of natives, this study aims at understanding the economy-wide impact of immigration.
We construct a new and unique dataset on migrant characteristics by age and education level in twenty OECD countries, decomposing total shares of migrants over natives by three age and two skill groups, by five-year intervals, in the period from 1960 to 2005, using individual country-year censuses and labor force surveys. Using these data, we study the impact of heterogeneous migration on income and labour productivity, as well as its main components: total factor productivity, physical capital, human capital, and employment. We do this by combining level accounting approach with panel income regressions, and thus analyzing through which channels the migration impact is diffused. The main findings are that, on average, immigrants have a positive impact on income and labour productivity in host countries, which works primarily through the TFP, and mostly in the long run. We show that this aggregate result can be explained by complementarities in age and education dimensions of immigrant relative to native population. There are also a few other channels, notably capital adjustment, through which the effect of immigration works. Currency Misalignments and Growth: a New Look using Nonlinear Panel Data Methods There has recently been a revival of interest in equilibrium exchange rates' assessment due to the current context of global imbalances. Indeed, since the end of the 1990s, the accelerating financial integration process accompanied with the preeminence of capital movements over trade in goods between countries, has engendered a growing disconnection between exchange rate fluctuations and the real economic activity. In order to assess long-run values of real exchange rates that would be consistent with the realization of a long-run stable macroeconomic equilibrium, various equilibrium exchange rate concepts have been developed, among which the Behavioral Equilibrium Exchange Rate (BEER).
Although numerous contributions have explored the links between exchange rate volatility or the choice of exchange rate regime and growth, the influence of long-run exchange rate misalignments on real economic activity remains an open question. Lasting misalignments may induce distortions in relative prices of traded-over-non traded goods that may be misinterpreted by economical agents and, as a consequence, may generate an insufficient resource allocation. In addition, the effects may be differentiated in case of an over- or undervaluation of currencies. Our aim is to investigate the relationship between real exchange rate misalignments and economic growth, while paying special attention to potential asymmetric effects of over-and underevaluation. Our contribution is threefold. First, while most of the previous studies consider developing countries, we rely on a wider sample of countries, including both developed and developing economies. This is of particular importance in the current context of global imbalances, that calls for a consistent set of equilibrium exchange rates. Second, we conduct a detailed analysis to derive robust measures of currency misalignments by relying on the BEER methodology. In this sense, we go further than most of the existing literature investigating the link between currencies and economic growth based on PPP measures of exchange rate misalignments. Third, we specifically account for the sign (and the size) of the misalignment by estimating a panel nonlinear model. More specifically we rely on the estimation of a Panel Smooth Transition Regression (PSTR) model, allowing for a differentiated impact of currencies' overvaluations and under-valuations on economic growth.

On Selective Tariff Cuts for Environmentally Preferable Products The opportunity to concede selective tariff reductions for certain Environmentally Preferable Products is under discussion within current WTO negotiations on Environmental Goods and Services. The underlying arguments in favour of such a "green liberalization" are to combine traditional gains from trade with environmental benefits from cleaner reduction/consumption, and also to improve developing countries' exporting capacities in green products. Using a simple North-South trade, partial equilibrium model with two goods (a conventional variety produced with a polluting technology, and a green substitute produced with an environmentally preferable technology), we analyze the validity of these three arguments, and provide a comparison with a full liberalization scenario (unselective tariff reduction for both varieties).
We show that, if consumers in the importing country value the "green" product, selective tariff cuts result in lower pollution levels in both countries, due to substitution in consumption patterns. Although the comparison of welfare implications under a green- and a full-liberalization scenario is ambiguous, it is possible to show that selective tariff reductions result in an interesting distribution of benefits among agents. However, simulations suggest that at the aggregated (country) level, neither a full nor a green liberalization is optimal, while it is possible to find Pareto-improving tariff reforms.

Market Potentials Database
The distribution of economic activities across countries is a subject of increasing interest in international economics. Empirically, economic geography is often described by indicators labelled “Market Potentials” or “Market Access”. The concept of Market Potentials goes back to Harris (1954). It states that a reliable proxy for the demand addressed to producers in a given location is the sum of expenditures in all locations, weighted by transport costs. Hence, Market Potentials combine in a single index the size of possible destination markets and trade frictions. New economic geography models (Fujita, Krugman and Venables, 1999) provide a solid theoretical background showing the impact of Market Potentials on countries and economic fortune.
Redding and Venable (2004) propose an original methodology to estimate such indicators of countries’ proximity to worldwide demand. They also show that market potentials have a strong influence on countries’ GDP per capita. Mayer (2008) provides evidence on the long-term impact of Market Potential on economic development. Besides, a large body of empirical work provides strong evidence that Market Potentials heavily determines multinational firms’ location choices (see for instance Head and Mayer, 2004). CEPII’s Market Potentials database provides indices synthesizing the evolution of countries’ economic geography. The database contains six distinct measures of Market Potential for a very large set of countries (between 152 and 205, depending of the year) and 44 years. This database is a practical tool to describe and study the evolution of economic geography of the world. Maps 1 and 2 show two examples. They display the evolution of market potential hierarchy for textiles and Professional and Scientific equipment respectively. Values are normalized as deviations from the mean of each industry, and they are grouped in five classes ranging from big progress (intense red) to big decline (soft yellow). Due to data limitations, it is not possible to compute a market potential for a number of countries in 1980 (blank on the maps). Map 1 Note: Rank evolution is the change in gained or lost places in the market potential hierarchy, relative to the United States. Values are normalized as deviations from the mean across regions, and they are grouped in 5 classes. The middle group is comprised between the mean +/- 0.5 standard deviation, and the next groups are delimited by 1 standard deviation. Blanks correspond to countries with no data.
For textile (Map 1), we notice a strong progression for China, Vietnam, Mexico, India and Turkey, and strong downfalls for Argentina, Iran, and Angola. A moderate progress is observed in some peripheral European countries (Spain, Portugal, Poland, Romania, etc), reflecting the proximity advantage, rather than low-wage competitiveness. Other countries avoid decline by virtue of their internal demand, like Brazil or the United States.
Map 2 Note: See Map 1.
Map 2 shows the rank evolution for the industry Professional & Science Equipment. Changes are much less pronounced than in Textiles, with Turkey, Vietnam and Poland gaining relatively important places in the world ranking. Ireland, China, India and other Asian countries exhibit moderate advances, and Latin American decline is noteworthy.

Bad Weather for the Stability and Growth Pact
N° 286, 2 April 2009 Everywhere in the world, the need for fiscal stimulus has caused a severe deterioration of fiscal balances and raised the unavoidable question of debt sustainability. In the Euro area, the recent initiation of Excessive Deficit procedures by the European Commission against the countries with high deficits has heated this debate. Still, the Euro area needs a credible scheme of budgetary discipline that would allow fiscal authorities to reassure sovereign debt markets and to dissipate the reticence of the ECB in adopting a policy of quantitative easing. That would also facilitate the implementation of fiscal stimulus packages, which could open an exit away from the crisis. Such a scheme should be designed to enforce more discipline, but also more counter-cyclical fiscal policies.
Terms of Trade and Exchange Rates: a Relationship Complicated by Anchor Policies
N° 285, 11 March 2009 The terms of trade of commodity-exporting countries are directly affected by the large-scale swings of worldwide prices. These terms of trade represent one of the key determinants of the real exchange rates of these economies. By estimating long-term equilibrium exchange rates we can gauge their impact for oil exporters and for exporters of other commodities. We then evaluate currency ‘misalignments’ as the discrepancies between the observed real exchange rates and their equilibrium values. Can these misalignments themselves be explained? In countries whose currencies are anchored to the dollar or to the euro, the misalignments are shown to depend on the behaviour of the anchor currency. When the anchor currency appreciates, the anchored currencies tend to be overvalued; when it depreciates, their undervaluation is likely. Virginie Coudert, Cécile Couharde & Valérie Mignon
Euro: as Expected, Gains and Costs
N° 284, December 2008 Ten years ago, eleven European countries, since joined by five others, gave up their national currencies to create the euro. This anniversary is the occasion to evaluate whether the promises regarding the euro were kept. Various studies undertaken on French exports indicate that the single currency indeed produced the expected microeconomic benefits of a reduction in the transaction costs and greater price transparency. However, the single currency policy has led to strong divergences of real interest rates between countries, whose effects have not been corrected for lack of suitable macroeconomic co-operation. Ten years after the creation of the euro, the bursting of the real estate bubble in certain countries of the zone and the consequences of the financial crisis point to the necessity of strongly counter cyclical macroeconomic policies in the monetary union.
