We consider a manager who allocates some fixed total payment amount between N rational agents in order to maximize the aggregate production. The profit of i-th agent is the difference between the compensation (reward) obtained from the manager and the production cost. We compare (i) the normative compensation scheme where the manager enforces the agents to follow an optimal cooperative strategy; (ii) the linear piece rates compensation scheme where the manager announces an optimal reward per unit good; (iii) the proportional compensation scheme where agent's reward is proportional to his contribution to the total output. Denoting the correspondent total production levels by s*, ? and s? respectively, where the last one is related to the unique Nash equilibrium, we examine the limits of the prices of anarchy AN = s*/s?, A'N = ?/s? as N ? ?. These limits are calculated for the cases of identical convex costs with power asymptotics at the origin, and for power costs, corresponding to the Coob-Douglas and generalized CES production functions with decreasing returns to scale. Our results show that asymptotically no performance is lost in terms of A'N , and in terms of AN the loss does not exceed 31%.

The Difference

In discussions of the economic problems of underdeveloped countries, the thinking of layman and of professional economists often diverges widely. Nowhere is this disagreement more patent than in the case of food production and its effects upon the price level. In government agencies, newspapers, and public discussions, the view that bad crops "cause" inflation is ubiquitous, while economists are usually quick to point out the difference between movements in relative prices and the general price level. The economists' view is sophisticated and requires elaboration. For nearly a century, there has been a division of economic problems into two basic categories:' those concerned with the value and production of particular commodities relative to other commodities; and those concerned with the total production of an economy and the general price level of the output. There is now an extensive theory of the effect of a decline in the output of a commodity (e.g., food) upon its price. Under most conditions, one can safely predict that an autonomous1 reduction in the output of food will induce a rise in the price of food relative to other prices. But there is no reason to expect a rise in the general price level; for that is determined by another theory a theory which does not concern itself with production of particular commodities, but rather with total production in the economy. If food output were a small part of this total production, the economist would say that the overall price level is not affected by a decline in food output; the rise in food prices, even if large, would be offset by slight declines in other prices2 so that the general price level would remain stable. Food production in Pakistan is, however, no small part of total output.

The current study aimed at evaluating technical efficiency and change in output of pulse crops in Karnataka. Totally 180 farmers were selected for eliciting required information on adoption of A3P technology. The results of the study revealed that majority of the farmers were operating above 80 per cent efficiency levels in both pulses across the farmers of A3P and Non-A3P. Further, more than 53 per cent of farmers' under redgram and 56 per cent under bengalgram have achieved 100 per cent efficiency level in A3P farmers category. Decomposition of the difference in total output between A3P and Non-A3P farmers was 13.23 and 14.86 per cent in redgram and bengalgram crops respectively. The A3P technology has alone contributed to the extent of 29 and 22 per cent to the total change in redgram and bengalgram output indicating output can be increased by about 29 and 22 per cent if the farmers could switch over from traditional practices (Non-A3P) to A3P technology. There is need to educate farmers on optimum use of inputs through conducting intensive trainings on A3P technology by KVK’s and other extension agencies to increase the supply of pulses in the country.

Abstract Background Coix seed is a traditional Chinese medicine with pharmacological effects and food efficacy. It is well-know and widely used in China and other Asian countries. Fayiren is a new artillery material processed from Coix Seed. This is the first study of the diuretic activities of Fayiren and coix seed in normal rats. Methods Forty-eight rats were randomly divided into 6 groups (8 rats/group) according to body mass and urine volume stratification, namely model (physiological saline) group, positive control (furosemide 20 mg/kg) group, coix seed (1666 mg/kg) group, low-dose of Fayiren group (166 mg/kg) and high-dose Fayiren group (1666 mg/kg). Rats were fasted for 16 h before the experiment, with normal water supply. Immediately after administration, each group of rat was placed in a metabolic cage, and urine was collected once after every hour for a total of 6 times. The urine volume at each time point for collection was measured, and then totaled. After the 6 h recording procedure, the treatments were administered once a day and the urine was collected at the 24th, 48th, 72th, 96th, 110th, 134th, and 158th hours from the start respectively. The urine pH and Na +, K +, Ca 2+, Cl - concentrations at each time point of each group of rats were measured. The contents of ALD, ANP, ADH, Na+-K+-ATPase, the gene expression and protein levels of AQP1, AQP2 and AQP3 in urine of rats in each group were determined. SPSS22.0 statistical software was used to analyze the experimental data. One way ANOVA and multiple comparisons between LSD groups were performed. The difference is considered significant When p < 0.05 or p < 0.01. Results After the administration of Fayiren and coix seed, compared with normal rats, the total output of urine in the high-dose coix seed & Fayiren group and the positive control group both increased; In addition, the contents of Na+ and Cl-in urine in these groups increased as well. However, the content of K+ did not increase in all groups. Contents of ALD and ADH was decreased and increased contents of ANP observed in urine in both high-dose and low-dose Fayiren groups with significant differences from model group (P < 0.05). Coix seed significantly reduced ADH and increased ANP levels compared with model group (P < 0.05). There was no obvious change in the urine pH content in urine of all rats. All the aquaporin (AQP1, AQP2, and AQP3) contents were decreased comparing to the model group, the coix seed group, as well as the Fayiren group. The effect of coix seed was particularly notable on AQP2, and the difference was significant against the Furosemide group (P < 0.05). By contrast, Fayiren showed greater effects on AQP1 and AQP3, with statistically significant difference comparing to the model group (P༜0.05). Conclusions This study will provide experimental evidence for explaining the different mechanisms of diuretic effects in natural medicine use of coix seed and artillery material processed from Coix Seed. The Fayiren may affect the reabsorption of water in the kidney through mechanisms related to increased ANP secretion,decreased ALD and ADH secretion in urine, and it significantly affect the expression of aquaporin 1 and aquaporin 3. However, coix seed may increase ANP but decreased ADH secretion, further affecting the expression of aquaporin2 and exert diuretic effect.

The Impact

This study estimates the impact of irrigation on household sticky rice productivity in Lao People’s Democratic Republic (Lao PDR) by applying propensity score matching (PSM) and the difference-in-differences (DID) method. This paper utilizes panel data from the Lao Expenditure and Consumption Survey (LECS) from 2003 to 2013. The results show that the average sales value and total production of sticky rice for irrigated households is greater than those for non-irrigated households by around 36 to 38% per season. Moreover, irrigated households experience improved sticky rice productivity of approximately 2.44 tons per hectare, per season, compared to non-irrigated households. In particular, compared to households with access to irrigation in one period of the surveys, households with access to irrigation in two periods of the surveys have nearly double the sticky rice productivity. Therefore, long-term access to irrigation is more effective for sticky rice productivity. However, we cannot find any evidence to support the impact of irrigation on household consumption. Some policy implications that can be derived from this research are that farmers should be intensively promoted to make the most use of irrigation, development of irrigation system is highly needed, and to ensure effectiveness of irrigation utilization local farmer involvement in monitoring procedure of irrigation is necessary.

Early Strain

A very early-flowering strain of subterranean clover was discovered in 1957 at Carnamah, W.A. From extensive studies at several field centres, it was demonstrated that the new strain – now called Carnamah – commenced flowering from 30 to 10 days before Dwalganup (the standard commercial "early" strain) when sown in the autumn-early winter period. With very early planting – late March – the difference in flowering time was even greater (about 45–50 days). The very early-flowering nature of the Carnamah strain is associated with early flower initiation. Rate of flower development (from flower initiation to flower appearance) in relation to temperature was similar for Carnamah and Dwalganup. Under spaced-plant conditions the total production of Carnamah was much less than that of Dwalganup, a finding which conforms to the results of previous single-plant studies. The new strain was not readily distinguished from Dwalganup, but several minor differences in morphology are mentioned. The chromosome number was normal for the species (2n = 16). The relevance of these data to sward conditions is discussed briefly, and it is suggested that the Carnamah strain may be more effective than Dwalganup in extending the "clover belt" inland in southern Australia.

The Difference

The concept of new and regenerated production has been used extensively in marine ecosystems but rarely in freshwaters. We assessed the relative importance of new and regenerated phosphorus (P) in sustaining phytoplankton production in Acton Lake, a eutrophic reservoir located in southwestern Ohio, USA. Sources of nutrients to the euphotic zone, including watershed loading, fluxes from sediments, and excretion by sediment-feeding fish (gizzard shad, Dorosoma cepedianum ), were considered sources of new P input that support new primary production and were quantified over the course of a growing season. Regenerated production was estimated by the difference between new and total primary production. New production represented 32%–53% of total primary production, whereas regenerated production represented 47%–68% of total primary production. P excretion by gizzard shad supplied 45%–74% of new P and 24% of P required for total production. In summary, fluxes of P from the watershed and those from sediment-feeding fish need to be considered in strategies to reduce eutrophication in reservoir ecosystems.

The Difference

Relationships between river discharge and production (catch) of the school prawn M. macleayi were examined as part of an ecological study of this species in the Clarence River region. Schooling behaviour of juvenile M. macleayi exhibited a lunar periodicity and mean daily abundance peaked 5 days after full moon. This was followed 7 days later by a peak in mean daily abundance of emigrating juvenile M. macleayi. Fluctuations in the magnitude of the oceanic component of the total annual catch were found to determine the difference between high and low production seasons. During the period examined there was a direct relationship between Clarence River discharge and the oceanic component of total production of M. macleayi, for various time periods. The absence of a persistent trend in total annual production and annual catch per unit effort of M. macleayi in the Clarence River region suggests that the stock has not been overfished. Common peaks in mean monthly oceanic production of M. macleayi off the Clarence, Evans and Richmond Rivers suggest a common enhancement of the seasonal emigration of M. macleayi from the three estuaries in November due to increased river discharges. Successive troughs and peaks in mean monthly oceanic production suggest a northwards migration of M. macleayi from the Clarence and Evans Rivers and subsequent recruitment to the Evans and Richmond ocean fisheries respectively. Results indicate the importance of river discharge to production of M. macleayi and suggest that modification of discharges by restriction of freshwater flow could adversely effect production.

Even in perfect competition there is a positive profit return if the good is produced with decreasing returns to scale technology. Using a two-periods overlapping generations (OLG) model with production under perfect competition with decreasing returns to scale technology in which the economy grows by technological progress and the older generation consumers receive the profit returns, we consider the problem of budget deficit under economic growth. We will show the following results. 1) We need a budget deficit to achieve full employment under constant price when the economy grows by technological progress. 2) If the budget deficit exceeds the level necessary to maintain full employment in a growing economy under constant price, inflation will be triggered. We need a stable budget deficit to prevent further inflation. 3) If the budget deficit is insufficient to maintain full employment, it will cause a recession with involuntary unemployment. We can overcome a recession and restore full employment caused by insufficient budget deficit by a budget deficit larger than the one necessary and sufficient to maintain full employment without a recession. We should not offset the deficit created to overcome the recession by subsequent surpluses because we can maintain full employment through constant budget deficits. Also, we show that in each case the budget deficit equals the difference between the net savings of the younger generation consumers and that of the older generation consumers.

Lemari Syukur Factory is a home industry that produces wardrobe cabinets. It determines selling price based estimation which is inappropriate. The main issue is that the company does not possess proper cost classification system in determining the cost of goods sold.  This research is aimed to assist determining the cost of production as the basis for making up finished goods price using full costing method. This research includes quallitative analysis research. Data were collected through interviews and documentation and analyzed by qualitative analysis techniques. The study resulted (1) for cost of goods sold calculation, the factory charged direct material costs of Rp. 325.000.000, direct labor cost of Rp. 211.200.000 and factory overhead cost of Rp. 556,800,000. Total production cost to produce 2,196 units of cabinets in one year amounted to Rp. 1.093.000.000. The factory estimated cost of goods sold for each unit is of Rp. 497.723, and the selling price per cabinet unit is Rp. 500.000. (2) Using full costing method, the cost calculation consisted of direct material costs of Rp. 325.000.000, direct labor cost equal to Rp. 211.200.000, factory overhead fixed cost Rp. 12,042,250, and variable factory overhead cost Rp. Rp. 525.550.000. Thus, the cost of production was Rp. 1,073,792,250 for 2,196 units of cabinets. The cost of goods sold per cabinet unit is Rp. 488.976 and the selling price is Rp. 619.559. (3) The difference in cost of goods sold between full costing and the factory calculation is of Rp 8.747. While the difference between finished product price using full costing and the factory estimation is Rp 133.766.

Abstract This study aimed to detect the most important factor that affects dates production. About 108 questionary forms collecttted palm orchard farmers in Karbala to estimate the dates production function in Karbala governorate for the agricultural season 2021 (the district of Al-jadual Al-Gharby). The study distributed those formmmsss for about 10% of the total palm orchards in Al-jadual Al-Gharby district of the holy governorate of Karbala. The study used the method of ordinary Least squares (OLS) to estimate the mathematical model of the function. The results showed that the double Logarithmic function in terms of its estimation of the estimated Coefficients by one unit leads to a corresponding change in the produced quality of dates and the same direction by 0.188 0.808) % respectively, and that the capital variable is more in fluently in production than the work variable. As for the total production elasticity (the sum of the partial elasticities of the resources used), which represents returns to scale, it amounted to about (0.996), which indicates a decrease in the return to scale.
