Work schedules, wages, and employment in a general equilibrium model with team production

An analysis of working hours, wages, and employment when production requires coordinating the work schedules of heterogeneous workers. The author shows that this coordination aspect of production can have important policy implications.Hours of labor ; Employment (Economic theory) ; Wages

Inventories and the business cycle: an overview

A review of research on the relationship between inventory investment and business cycle fluctuations, focusing on the developments of the last 15 years. A central issue in the literature, the relative importance of demand and supply shocks as sources of fluctuations, continues to be debated.Inventories ; Business cycles

An introduction to the search theory of unemployment

The author presents a model of job search that focuses on an unemployed person's decision to accept an offered job or to continue looking for a new one.Unemployment

Money growth and inflation: how long is the long run?

In their efforts to maintain low inflation, policymakers pay little attention to the growth rate of the money supply. Yet many studies have found that money growth and inflation a closely related, at least in the long run. But how long must money growth remain strong before it begins to concern policymakers? That is, what is the shortest period over which money growth seems to be reliably associated with inflation?Inflation (Finance) ; Money supply ; Monetary policy

Drying of post-harvest rough rice with silica gel: A preliminary investigation

Rice drying operations can encounter problems of over drying and losses in head rice yield (HRY) through the formation of fissures. Typical rice drying methods also utilize large volumes of expensive fossil fuels to dry the kernels. Drying of rice with a solid desiccant such as silica gel has several potential advantages that avoid some of these problems. Two cultivars of long-grain rough rice, ‘Cheniere’ and ‘Wells’ with harvest moisture contents of 17.8% and 22.0%, respectively, were dried over a 48-h period with various ratios of rough rice-to-silica gel. It was found that an intimate mixture of 3:1 rough rice to silica gel was sufficient to dry these rice lots to 12.5% and 14.3% within 12 h, respectively. Head rice yields of desiccant-dried rice showed no considerable differences from the control. Rough-rice drying curves for all rough rice-to-silica gel mixtures followed exponential relationships

Polyimide molding powder, coating, adhesive, and matrix resin

The invention is a polyimide prepared from 3,4'-oxydianiline (3,4'-ODA) and 4,4'-oxydiphthalic anhydride (ODPA), in 2-methoxyethyl ether (diglyme). The polymer was prepared in ultra high molecular weight and in a controlled molecular weight form which has a 2.5 percent offset in stoichiometry (excess diamine) with a 5.0 percent level of phthalic anhydride as an endcap. This controlled molecular weight form allows for greatly improved processing of the polymer for moldings, adhesive bonding, and composite fabrication. The higher molecular weight version affords tougher films and coatings. The overall polymer structure groups in the dianhydride, the diamine, and a metal linkage in the diamine affords adequate flow properties for making this polymer useful as a molding powder, adhesive, and matrix resin
