In this paper we investigated the hypothesis of export spillovers from foreign multinationals to domestic firms using a data set of UK manufacturing firms from 1992 to 1999. Unlike previous studies we allow not only for the possibility of horizontal (i.e. intra-industry) and regional externalities, but also for vertical ones (i.e. inter-industry: forward and backward). Deploying and Heckman sel...

In the 1970s, taxation of "windfall" profits from primary products and intervention in trade and production tempted governments into expansionary fiscal policies, whilst stifling the private sector and depressing growth. However, the experience of the recent coffee boom has so far been more favourable: those African countries which liberalized and left a large share of the “windfall” with the p...

Using a bilateral trade equation derived from a monopolistic competition model, we investigated market access reciprocity in food trade among the US, Canada, the EU and Japan. We explore country and industry–specific market access asymmetry through the border effect approach, re-challenging the underlying main explanations. Our findings reveal marked asymmetry in reciprocal trade openness; inde...

We analyze how economic shocks and policies affect the intensity of social conflict. We view conflict phenomena such as crime and civil war as involving resource appropriation activities. We show that not all shocks that could make society richer reduce conflict. Positive shocks to labor intensive industries diminish social conflict, while positive shocks to capital intensive industries increas...

We consider optimal trade policy for a large country with private information. We show that the optimal tariff leads to a signaling equilibrium with higher tariffs and lower welfare than under complete information, whereas the optimal import quota replicates the complete information equilibrium and thus is superior to the tariff. We also show that, with the tariff, the country may be better off...

Pseudomonas sp. MX-058 produces aldehyde oxidase catalysing glyoxal to glyoxylic acid. Two aldehyde oxidases (F10 and F13) were purified to homogeneity from Pseudomonas sp. MX-058. F10 and F13 had subunit structures, a heterotetramer and heteropentamer respectively. The N-terminal amino acid sequences of all subunits were highly homologous to amino acid sequences of the putative oxidoreductases...

The purpose of the present investigation was to prepare an intranasal in situ gel with increased nasal residence time in order to improve bioavailability of metoprolol tartrate. The in situ gel systems containing carbopol, hydroxypropyl methylcellulose K4M and K15M in different concentrations were prepared. The samples were characterized for viscosity, rheological behavior, gelation behavior, g...
