A contribution to the empirics of convergence in real GDP growth: the role of financial crises and exchange-rate regimes

This paper investigates the convergence in real gross domestic product growth focusing on the impact of financial crises (i.e. banking crises, currency crises and debt crises) and nominal exchange-rate regimes (i.e. fixed, intermediate and flexible) on convergence. To that end, we compute four convergence indicators (σ-convergence, γ-convergence, absolute β-convergence and conditional β-convergence) for 163 countries classified into four income groups during the period 1970–2011. The results suggest that (i) there is evidence in favour of σ-convergence and γ-convergence only for high-income countries; (ii) absolute and conditional β-convergence are present in each of the four income groups of the countries under study; (iii) exchange-rate regimes seem to play some role in upper-middle and lower-middle-income countries; and (iv) financial crises have a negative and significant impact on GDP growth independently of the income level of the countries.

Market and Welfare Effects of Second-Generation, Consumer-Oriented GM Products

We examine the economic effects of the introduction of consumer-oriented genetically modified (GM) products into the food system by developing a model of heterogeneous consumers and producers that allows for vertical and horizontal differentiation between the products available to consumers. The model facilitates the estimation of consumer and producer surpluses in the product/utility and product/net returns spaces. Results show that the introduction of consumer-oriented GM products can change the relationship between GM and conventional and organic products from one of vertical to one of horizontal product differentiation and can enhance both economic welfare and the market acceptance and growth of agricultural biotechnology.
