Tourism Demand in Portugal: Market Perspectives

Tourism has experienced different levels of development in the different regions of Portugal. To frame this development, several panel data models were estimated. The main objective is to explain the evolution of overnight stays by nationality in each region. Secondary data from 2000 to 2010 was used. The analysis includes the main tourism markets, such as the United Kingdom, Germany, the Netherlands, Ireland, France and Spain. Tourism literature suggests that, among others, the main determinants of tourism demand are Income (GDP), population, tourist´s income by place of residence, households’ consumption, unemployment rate, inflation rate, compensation of employees, comparative prices and households’ investment rate. It is observed that, although significant, the explanatory power of these variables varies according to the origin and the destination region considered

LONG-TERM HEDGING ANALYSIS FOR SOYBEANS, 1973-95

The study analyzed a two-year hedge for soybeans in three states trying to capture high prices. The differences in prices received over a 23 year period were not significant when compared to annual hedges or cash sales.Demand and Price Analysis, Marketing,

Diffusion-annihilation dynamics in one spatial dimension

We discuss a reaction-diffusion model in one dimension subjected to an external driving force. Each lattice site may be occupied by at most one particle. The particles hop with asymmetric rates (the sum of which is one) to the right or left nearest neighbour site if it is vacant, and annihilate with rate one if it is occupied. We compute the long time behaviour of the space dependent average density in states where the initial density profiles are step functions. We also compute the exact time dependence of the particle density for uncorrelated random initial conditions. The representation of the uncorrelated random initial state and also of the step function profile in terms of free fermions allows the calculation of time-dependent higher order correlation functions. We outline the procedure using a field theoretic approach.Comment: 26 pages, 1 Postscript figure, uses epsf.st

U.S. --MEXICO FOOD SYSTEMS AND THE TOMATO TRADE DISPUTE

Mexican produce exports into the U.S. increased considerably during the latter months of 1995 and the first nine months of 1996. Because of these increased imports, Florida tomato growers requested the executive branch of the U.S. government and Congress to put into effect seven trade protection measures to reduce or stop fresh tomato imports from Mexico. This study was carried out to determine if the United State Department of Commerce (USDOC) and the United States International Trade Commission (USITC) found valid and reliable indications that the tomato industry in the U.S. was materially injured by imports from Mexico.International Relations/Trade,
