Profitability of dairy farming in relation to the type of feeding systemWe investigated the profitability of dairy farms in relation to the type of feeding system (seasonal pasture vs. permanent housing). An economic analysis was carried out of data on the structure and financial health of 50 farms in 2007 using questionnaires filled in by the farmers. The Principal Component Analysis (PCA) was applied to reveal causal relationships between a number of characteristics of the farms. The two axis of PCA explained 40.48% and 16.13% of the variability among the selected farm characteristics. Profitability related more to the number of subsidies, the area of arable land, the number of livestock and to the milk and plant production than to the area of meadows and pastures. Although a better cow performance was achieved on farms with confined herds, the profit per agricultural area and profit rate did not differ significantly between the two feeding strategies (P>0.05). The profit was 3,259 and 3,655 CZK/ha on average and the profit rate 7.9% and 5.6% on average on farms with pastured herds and on farms with confined herds, respectively. A lowering of input costs and a more effective utilisation of grasslands may further enhance profitability.

AbstractInteraction effect across complementary products plays an important role in characterizing the optimal inventory policy. The inventory levels of complementary products are interrelated due to interaction between demand streams. In this paper, we consider a periodic review base-stock policy in the presence of two complementary products with interrelated demands and joint replenishment. Demands are modeled by a Poisson process and any unmet demand is lost. Demands can be in sets of one unit of each or jointly. If an arrival demand requests two products jointly and one of the products is not in stock, then the whole demand is lost. We aim to investigate how this interrelated demand phenomenon influences the optimal base-stock levels and the period length of a periodic review policy. We utilize the renewal reward theorem to derive the explicit expression of the expected profit rate in the system. The goal is to determine the optimal period length and the base-stock levels such that the expected profit rate is maximized. Enumeration and approximation algorithms are employed to find the optimal and near-optimal solutions, respectively. The approximation algorithm is based on a scenario with independent demand processes which results in an explicit expression for the long-run profit per time unit and leads to analytical solutions for optimal policies. Our numerical results reveal that the solutions obtained by the approximation algorithm are close to optimal solutions. Numerical experiences show that the maximum profit in the system is achieved if the proportion of customers with jointly demand increases. Moreover, the interaction effect between demand processes has a significant impact on the control policy performance when the units lost sales and unit holding costs are high, and the demand rare is low.

The study is based on a total number of seven full-fledged listed Islamic Banks operating in Bangladesh. Secondary sources of data are used in this research. Data were collected from the Website of Bangladesh Bank and studying relevant literatures. This paper examines whether there is any differences of profit rate on deposits among different Islamic Banks. It also aims at finding whether there is any relationship between inflation and profit rate on deposits. Analyses have been done for two types of deposits accounts called Mudaraba Term Deposits Account and Mudaraba Savings Account. The results of the study reveal that, in case of Term Deposits the highest mean return is 11.06458% as offered by the First Security Islamic Bank Ltd. and the lowest mean return of 8.687500% is offered by Export Import Bank of Bangladesh Ltd. while in case of Mudaraba Savings Deposits the highest mean return of 6.583333% is offered by the First Security Islamic Bank Ltd. and the lowest mean return of 4.330417% is offered by Al Arafah Islami Bank Ltd. during the studied period. One sample t-test has been applied to find whether there is any significant difference in profit rate in different months and the study unfolds that the profit rate differs significantly in all the banks from month to month. The findings of Paired Sample t-test suggests that there is a significant difference in mean return between the Islamic banks in both of the Mudaraba Term Deposits and Mudaraba Savings Accounts in all the cases except for two pairs as the return on savings deposit does not significantly differ between Al Arafah Islami Bank Ltd. and Social Islami Bank Limited while it does not differ significantly between Social Islami Bank Limited and Islami Bank Bangladesh Ltd. in case of Mudaraba Term Deposits. Finally, the relationship between inflation and rate of profit is found insignificant in case of Mudaraba Saving Deposits while significant relationship has been discovered between Mudaraba Term Deposits and rate of inflation.IIUC Studies Vol.10 & 11 December 2014: 81-98

Along this line of reasoning, the following hypothesis is put forth and tested: The ECB has used both the real unit labour costs (RULC) and the general profit rate as fundamental instruments to achieve economic growth and price stability in the Eurozone during the period 1999-2018. A Panel ARDL model and Granger causality test were applied to empirically contrast the above hypothesis.<strong></strong></p>

AbstractThe purpose of this paper is to investigate the variables that influence Islamic banking markets in Indonesia. The research data were obtained directly from the website of the Central Statistics Agency (BPS) and the financial services authority(OJK) from 2011-2018 which were taken on a quarterly basis. This study uses multiple regression analysis to analyze the factors that have an impact on the market share of Islamic banks in Indonesia. The variable that can affect Islamic banking marketshare in Indonesia is the liquidity ratio (FDR). While other variables such as the default rate (NPF), profit rate (ROA), economic growth (GDP) and conventional bank interest rates (INT) do not affect Islamic banking. The results suggest that Islamic banking regulates liquidity ratios (FDR) so that Islamic banking can effectively increase its market. This study complements previous research so that Islamic banking maintains a liquidity ratio in order to remain balanced.Keywords: marketshare, Islamic banking, FDR, GDP, ROA
