In this paper, we develop a North-South endogenous growth model to examine three phases of development in the South: imitation of Northern products, imitation and innovation and nally, innovation only. In particular, the model has the features of catching up (and potentially overtaking) which are of particular relevance to the Paci c Rim economies. We show that the possible equilibria depend on...

Technology spillovers o¤er great opportunities for economic growth to developing countries that do little, if any, R&D activity. This paper explores the extent to which these countries bene…t from foreign technology, the di¤usion mechanisms involved, the factors that shape their absorption capabilities, and the sources of heterogeneity in the spillover gains. Results based on a non-stationary p...

The applicability of the Bene s approach to the \fractional Brownian storage", i.e. a storage model where the net input process is a fractional Brownian motion (FBM) with drift, is studied. This requires the analysis of the last exit time probability density of a drifted FBM that, in turn, motivates the proof of a general \localization theorem" for FBM. The resulting Bene s formula contains a u...

To assess the impact of tax-bene…t policy changes on income distribution over time, we suggest a methodology based on counterfactual simulations. We start by decomposing changes in inequality/poverty indices into three contributions: reforms of the tax-bene…t structure (rules, rates, etc.), changes in nominal levels of market incomes and tax-bene…t parameters (bene…t amounts, tax bands, etc.), ...

This paper investigates design alternatives for shared network caches in clusterbased multiprocessors. Using simulation, we rst demonstrate that network caches o er several potential performance bene ts, but that the adverse impact of cache inclusion-related evictions must be mitigated for these bene ts to be fully realized. We then evaluate three network cache architectural alternatives design...

Rapid larval growth is essential in the development of most metazoans. In this article, we show that bene, a gene previously identified on the basis of its oogenesis defects, is also required for larval growth and viability. We show that all bene alleles disrupt gatA, which encodes the Drosophila homolog of glutamyl-tRNA(Gln) amidotransferase subunit A (GatA). bene alleles are now referred to a...

The consequences of free trade are investigated in an international duopoly under horizontal di¤erentiation and convex transportation costs. It is shown that the smaller country may bene...t from trade if it is su¢ciently small to allow for a signi...cant volume of exports by the domestic ...rm. On the contrary, the larger country never bene...ts from trade, since liberalization decreases the d...

This paper introduces gain-cost classi…cation matrix for targeting customer groups. A real life application was realized on a customer database of CCF Bank containing more than 400,000 instances. Results shows that scoring is almost insensitive to di¤erent cost-gain hypothesis; on the other hand, the optimal targeted group size and the expected global bene…t rely to cost-gain hypothesis. Keywor...
