A simple model of brain circulation

This paper analyzes the allocation of two types of individuals differentiated by talent between two countries where they choose to be workers or entrepreneurs. An equilibrium with international migration exists when countries' talent endowments are sufficiently different. It is consistent with one-way or two-way migration whether individuals are entrepreneurs or workers. Although allowing migration increases domestic welfare in one country and decreases it in the other, it is always supported by majority voting in both countries.     

Do trade costs in goods market lead to home bias in equities?

Two of the main puzzles in international economics are the consumption and the portfolio home biases. We solve for international equity portfolios in a two-country/two-good stochastic equilibrium model with trade costs in goods markets. We show that introducing trade costs, as suggested by Obstfeld and Rogoff [Obstfeld, M., Rogoff, K., 2000a. The Six Major Puzzles in International Macroeconomics: Is There a Common Cause? NBER Macroeconomics Annual, 15], is not sufficient to explain these two puzzles simultaneously. On the contrary, we find that trade costs create a foreign bias in portfolios for reasonable parameter values. This result is robust to the addition of non-tradable goods for standard calibrations of the preferences.     

Why parallel trade may raise producers' profits

This paper shows that a manufacturer may benefit from parallel trade. In addition to an intuitive condition about the effect of demand shocks, this occurs when competitive retailers must order inventories before they know the realization of demand and for products whose sale value drops at the end of the demand period. For these types of products, letting retailers trade unsold inventories generally results in larger orders placed with the manufacturer and higher manufacturer profit. The model provides a simple explanation as to why the volume of parallel trade is now very large and accepted by manufacturers for some products such as automobiles, clothes, toys, consumer electronics, musical recordings, cosmetics and perfumes.     

A STRUCTURAL RISK‐NEUTRAL MODEL FOR PRICING AND HEDGING POWER DERIVATIVES

We develop a structural risk‐neutral model for energy market modifying along several directions the approach introduced in Aïd et al. In particular, a scarcity function is introduced to allow important deviations of the spot price from the marginal fuel price, producing price spikes. We focus on pricing and hedging electricity derivatives. The hedging instruments are forward contracts on fuels and electricity. The presence of production capacities and electricity demand makes such a market incomplete. We follow a local risk minimization approach to price and hedge energy derivatives. Despite the richness of information included in the spot model, we obtain closed‐form formulae for futures prices and semiexplicit formulae for spread options and European options on electricity forward contracts. An analysis of the electricity price risk premium is provided showing the contribution of demand and capacity to the futures prices. We show that when far from delivery, electricity futures behave like a basket of futures on fuels.     

Psychological Capital: Impacts on Asset Management

Drawing together the areas of behavioral finance and positive psychology, the present research sought to investigate whether the psychological capital of investment fund managers is associated with fund performance in a context of financial instability. The theoretical propositions were presented and evaluated empirically through primary data on investment fund manager profiles and secondary data on the cumulative stock fund returns. The results indicate that funds managed by managers with greater resilience and optimism obtained a higher return than the mean profitability in a period of market instability.     

Towards a New Trade Policy Between the USA and Middle‐East Countries:Estimating Trade Resistance and Export Potential

At the time of the conclusion of free trade areas (FTAs) between the USA and Middle‐East and North African (MENA) countries, there is a lack of literature concerning the measurement of the current US export position with regards to these countries, and the US export potential in this area. From recent developments of gravity models, this paper derives an estimable equation which includes various trade resistance variables, notably border effects, multilateral resistance as well as specific bilateral effects. The model is tested in order to scrutinise the impact of these variables on US exports to MENA countries, as well as the US export potential in this area. To that end, a selection of panel data specifications is proposed, mainly Hausman and Taylor models as well as Arellano and Bond dynamic models. Results unambiguously indicate that as compared to the other OECD countries, the USA suffers from a substantial trade integration deficit with MENA countries. This is reflected by the strongly negative values of the US‐MENA bilateral fixed effects, as well as the high bilateral border effects. In addition, the estimated actual/potential US export ratio to these countries is only 0.76. Therefore, implementing an FTA between the USA and MENA countries may allow the former to progressively improve its export position in this area. This would also help MENA countries diversify their supplying sources.

Experts,Information, Reviews,and Coordination: Evidence on How Prizes Affect Sales*

Exploiting the award process, we implement a regression discontinuity design to estimate the effect of winning France's main literary prize, the Goncourt. It increases sales, especially for books that sold fewer copies before the announcement, the number of reviews on Amazon, and the probability of them being negative. The effect is partly driven by an increase in word of mouth. Those findings are consistent with a model where the prize provides information on the existence of a book and acts as a quality signal and a coordination device but prompts consumers to read books that are far from their tastes.
