There is ahvays a temporary tradeoff befween inflation and unemploy from inflation per se, but from unanticipated inflation, which generally means, from a rising rate of inflation Milton friedman Most economists analyze short-run fluctuations in aggregate income and the price level using the model of aggregate demand and aggregate supply. In the IS-LM modek hapters, we examined aggregate demand in some detail. The IS-LM model-together with its open-economy cousin the Mundell-Fleming model-shows how changes in monetary and fiscal policy and shocks to the money and goods markets shift the aggregate demand curve. In this chapter

When conducting monetary and fiscal policy, policymakers often look be- yond their own country's borders Even if domestic prosperity is their sole ob jective, it is necessary for them to consider the rest of the world. The international flow of goods and services and the international flow of capital can affect an economy in profound ways. Policymakers ignore these effects at In this chapter we extend our analysis of aggregate demand to include inter- national trade and finance. The model developed in this chapter, called the Mundell-Fleming model, is an open-economy version of the IS-LM model. Both models stress the interaction between the goods market and the money market. Both models assume that the price level is fixed and then show what

Aggregate Demand ll Science is a parasite: the greater the patient population the better the ad ance in physiology and pathology; and out of pathology arises therapy The year 1932 was the trough of the great depression, and from its rotten soil was belatedly begot a new subject that today we call macroeconomics In Chapter 10 we assembled the pieces of the IS-LM model. We saw that the IS curve represents the equilibrium in the market for goods and services, that the LM curve represents the equilibrium in the market for real money balances, and that the IS and LM curves together

Preservative packagings for fresh meats should maintain acceptable appearance odour and flavour for product, while allowing the development of desirable characteristics associated with ageing and retarding the onset of microbial spoilage(Taylor, 1985). Such effects can be achieved by packaging meats under various atmospheres of oxygen, carbon dioxide, carbon monoxide and/or nitrogen. The atmosphere within a pack may alter during storage, because of reactions between components of the atmosphere and the product, and/or because of transmission of gases into or out of the pack through the packaging

Modified atmosphere packaged (MAP )prepared fresh produce provides substrates and environmental conditions conducive to the survival and growth of microorganisms. Minimal processing treatments such as peeling and slicing disrupt surface tissues, expose cytoplasm and provide a potentially richer source of nutrients than intact produce(Brackett 1994; Barry-Ryan and O'Beirne, 1998, 2000). This, combined with high Aw and either close to neutral (vegetables) or low acid (many fruits) tissue pH, facilitate microbial growth (Beuchat, 1996)

The packaging sector is an important global industry, representing about 2% of the Gross National Product (GNP) of the developed countries. The value of the packaging industry is about 345 million euros worldwide, of which Europe represents a third. Fifty per cent of this market is packaging for food. Forecasts suggest that the sector will continue to grow in size and importance Many cooking and preservation processes still largely depend on effective packaging, for example canning, aseptic, sous vide and baking processes. Processes such as drying and freezing would be lost without protective packaging after processing to control product exposure to the effects of oxygen light, water vapour, bacterial and other contaminants. However, modern food packaging no longer has just a passive role in protecting and marketing the product. It increasingly has an active role in processing, preservation
